Preliminary Proxy Statement

PROXY STATEMENT PURSUANT TO SECTION 14(a) OF THE SECURITIES EXCHANGE ACT OF 1934 (AMENDMENT NO. )

20,538,737 shares of DDi common stock and 2,586,452 shares of DDi common stock underlying outstanding stock options with exercise prices less than $13.00 per share, each outstanding as of March 30, 2012.

The filing fee was determined based on the sum of (a) 20,538,737 shares of DDi common stock multiplied by $13.00 per share and (b) 2,586,452 shares of DDi common stock underlying outstanding stock options with exercise prices less than $13.00 per share multiplied by $5.78 (which is the difference between $13.00 per share and the weighted average exercise price per share). The filing fee was determined by multiplying 0.00011460 by the sum of the preceding sentence.

You are cordially invited to attend a special meeting of stockholders of DDi Corp. (“DDi”) to be held on [ ], at 8:00 a.m., local time, at DDi’s corporate headquarters, located at 1220 N. Simon Circle, Anaheim, California 92806.

At the special meeting, you will be asked to consider and vote upon a proposal to adopt the Agreement and Plan of Merger, dated as of April 3, 2012, by and among Viasystems Group, Inc. (“Viasystems”), Victor Merger Sub Corp., a wholly-owned subsidiary of Viasystems, and DDi, as such agreement may be amended from time to time. Pursuant to the merger agreement, Victor Merger Sub Corp. will merge with and into DDi and as a result, under Delaware law, DDi will become a wholly-owned subsidiary of Viasystems. We are also asking that you grant the authority to vote your shares in favor of adopting the merger, to adjourn the special meeting to a later date, if necessary or appropriate, to solicit additional proxies in the event there are not sufficient votes in favor of adoption of the merger agreement at the time of the special meeting and to approve, on an advisory (non-binding) basis, certain compensation that may be paid or become payable to DDi’s named executive officers in connection with the merger.

If the merger is completed, DDi stockholders will be entitled to receive $13.00 in cash, without interest and less any applicable withholding taxes, for each share of DDi common stock owned by them as of the date of the merger (unless they have not voted for or consented to the merger and have demanded properly in writing their statutory rights of appraisal).

Our board of directors unanimously determined that the terms and conditions of the merger and the merger agreement are fair to and advisable and in the best interests of DDi and our stockholders. Accordingly, our board of directors has unanimously approved the merger agreement, the merger and the other transactions contemplated thereby, and unanimously recommends that you vote “FOR” the adoption of the merger agreement, “FOR” approval of the proposal to adjourn the special meeting, if necessary or appropriate, to solicit additional proxies and “FOR” the approval, on an advisory (non-binding) basis, of certain compensation that may be paid or become payable to DDi’s named executive officers in connection with the merger.

Our board of directors considered a number of factors in evaluating the transaction and consulted with our legal and financial advisors. The enclosed proxy statement provides detailed information about the merger agreement and the merger. We encourage you to read this proxy statement carefully in its entirety.

Your vote is very important, regardless of the number of shares you own. The proposal to adopt the merger agreement must be approved by the holders of a majority of the outstanding shares of our common stock entitled to vote at the special meeting. Therefore, if you do not return your proxy card in the mail, submit a proxy via the Internet or telephone or attend the special meeting and vote in person, then your decision not to respond will have the same effect as if you voted “AGAINST” the adoption of the merger agreement. A failure to submit a proxy or vote in person will have no effect on the adjournment proposal or the proposal regarding the merger-related executive compensation, if a quorum is present. An abstention will have (i) the same effect as if you voted “AGAINST” the adjournment proposal, whether or not a quorum is present and (ii) no effect on the proposal regarding the merger-related executive compensation, provided a quorum is present. Only stockholders who owned shares of DDi common stock at the close of business on [ ], the record date for the special meeting, will be entitled to vote at the special meeting. To vote your shares, you may return your proxy card, submit a proxy via the Internet or telephone or attend the special meeting and vote in person. Even if you plan to attend the meeting, we urge you to promptly submit a proxy for your shares via the Internet or telephone or by completing, signing, dating and returning the enclosed proxy card.

This proxy statement is dated [ ] and is first being mailed to stockholders of DDi on or about [ ].

DDi Corp., a Delaware corporation (“DDi”), will hold a special meeting of stockholders at DDi’s corporate headquarters, located at 1220 N. Simon Circle, Anaheim, California 92806, at 8:00 a.m., local time, on [ ], for the following purposes:

Only record holders of DDi common stock at the close of business on [ ] are entitled to receive notice of, and will be entitled to vote at, the special meeting, including any adjournments or postponements of the special meeting. Your vote is important, regardless of the number of shares of DDi’s common stock you own. The affirmative vote of the holders of a majority of the outstanding shares of DDi common stock entitled to vote at the special meeting is required to adopt the merger agreement. The affirmative vote of a majority of the shares of DDi common stock present in person or represented by proxy and entitled to vote at the special meeting is required to approve the proposal to adjourn the special meeting, whether or not a quorum is present, and the affirmative vote of a majority of the shares of DDi common stock present in person or represented by proxy and entitled to vote at the special meeting and casting a vote for or against such matter is required to approve certain merger-related executive compensation, provided that a quorum is present.

Under Delaware law, if the merger is completed, holders of DDi common stock who do not vote in favor of adoption of the merger agreement will have the right to seek appraisal of the fair value of their shares as determined by the Delaware Court of Chancery. In order to exercise your appraisal rights, you must (i) submit a written demand for an appraisal of your shares prior to the stockholder vote on the merger agreement, (ii) not vote in favor of adoption of the merger agreement and (iii) comply with other Delaware law procedures explained in the accompanying proxy statement.

A return envelope (for which postage has been prepaid if mailed in the United States) is enclosed for your convenience. Even if you have voted by proxy, you may still vote in person if you attend the special meeting. Please note, however, that if your shares are held of record by a broker, bank or other nominee and you wish to vote at the special meeting, you must obtain a proxy issued in your name from that record holder.

If you sign, date and return your proxy card or submit a proxy via the Internet or telephone without indicating how you wish to vote, your proxy will be voted “FOR” the adoption of the merger agreement, “FOR” the adjournment of the special meeting to a later date, if necessary or appropriate, to solicit additional proxies in the event there are not sufficient votes in favor of adoption of the merger agreement at the time of the special meeting and “FOR” the approval, on an advisory (non-binding) basis, of certain compensation that may be paid or become payable to DDi’s named executive officers in connection with the merger. If you do not return your proxy card in the mail, submit a proxy via the Internet or by telephone or attend the special meeting and vote in person, then your decision not to respond will have the same effect as if you voted “AGAINST” the adoption of the merger agreement. A failure to submit a proxy or vote in person will have no effect on either (i) the proposal to adjourn the special meeting to a later date, if necessary or appropriate, to solicit additional proxies or (ii) the proposal to approve, on an advisory (non-binding) basis, certain compensation that may be paid or become payable to DDi’s named executive officers in connection with the merger, provided that a quorum is present. An abstention will have (i) the same effect as if you voted “AGAINST” the adjournment proposal, whether or not a quorum is present and (ii) no effect on the proposal regarding the merger-related executive compensation, provided a quorum is present. If you do attend the special meeting and wish to vote in person, you may revoke your proxy and vote in person.

You may obtain the information incorporated by reference into this proxy statement without charge by following the instructions under “Where You Can Find More Information” beginning on page 82.

In addition, throughout this proxy statement, we refer to DDi Corp., as “DDi,” to Victor Merger Sub Corp. as “merger sub” and to Viasystems Group, Inc. as “Viasystems.”

In addition, you are being asked to grant to the proxies identified in the enclosed proxy card discretionary authority to adjourn the special meeting to a later date, if necessary or appropriate, to solicit additional proxies in the event there are not sufficient votes in favor of adoption of the merger agreement. If we do not receive proxies from stockholders holding a sufficient number of shares to adopt the merger agreement, we could use the additional time to solicit additional proxies in favor of adoption of the merger agreement.

Additionally, you are being asked to approve, on an advisory (non-binding) basis, certain compensation that may be paid or become payable to DDi’s named executive officers in connection with the merger.

Although we are authorized to issue restricted stock units, which we refer to as RSUs, and restricted stock, we currently do not have any RSUs or restricted stock outstanding, and we have agreed under the terms of the merger agreement not to issue any RSUs or restricted stock prior to the effective time of the merger.

As of [ ], the record date for determining who is entitled to vote at the special meeting, there were [ ] shares of our common stock issued and outstanding.

Our bylaws provide that a quorum is present at the special meeting if the holders of a majority in voting power of the shares of our common stock issued and outstanding and entitled to vote at the meeting are present in person or represented by proxy.

If your shares are held in “street name” through a broker or other nominee, you may provide voting instructions by completing and returning the voting form provided by your broker or nominee, or via the Internet or telephone through your broker or nominee, if such a service is provided.

Merger Consideration and Treatment of Stock Options (page 52)

If the merger is completed, you will be entitled to receive $13.00 per share in cash, without interest and less any applicable withholding taxes, in exchange for each share of DDi common stock that you own immediately prior to the effective time of the merger (other than shares which you have not voted in favor of the merger and for which you have properly demanded appraisal rights).

Each option to acquire shares of our common stock that is outstanding and unexercised immediately prior to the effective time of the merger, and that is not then vested and exercisable, shall become fully vested on an accelerated basis immediately prior to the effective time of the merger. As of the effective time of the merger, each option to acquire shares of our common stock that is outstanding and unexercised immediately prior thereto shall be canceled in exchange for the right to receive from Viasystems or the surviving corporation as soon as practicable after the effective time of the merger an amount in cash (without interest, and less all applicable deductions and withholding required by law) equal to the product of (i) the excess, if any, of the merger consideration of $13.00 per share over the exercise price per share of common stock payable under such option multiplied by (ii) the number of shares of our common stock that are subject to such option.

Although we are authorized to issue RSUs and restricted stock, we currently do not have any RSUs or restricted stock outstanding, and we have agreed under the terms of the merger agreement not to issue any RSUs or restricted stock prior to the effective time of the merger.

Opinion of DDi’s Financial Advisor (page 29)

We retained Jefferies & Company, Inc., or Jefferies, to provide us with financial advisory services in connection with the merger and an opinion as to the fairness to holders of shares of our common stock of the consideration to be received by such holders in connection with a possible merger, sale or other strategic business combination.

Jefferies’ opinion sets forth, among other things, the assumptions made, procedures followed, matters considered and limitations on the scope of the review undertaken by Jefferies in rendering its opinion. Jefferies’

The full text of the written opinion of Jefferies is attached hereto as Annex B. We encourage you to read Jefferies’ opinion carefully and in its entirety. For a further discussion of Jefferies’ opinion, see “The Merger—Opinion of DDi’s Financial Advisor” beginning on page 29.

Interests of DDi’s Executive Officers and Directors in the Merger (page 38)

When considering the recommendation of our board of directors, you should be aware that members of our board of directors and our executive officers have interests in the merger in addition to their interests as DDi stockholders generally, pursuant to certain agreements between such directors and executive officers and DDi and, in the case of Mikel H. Williams, our Chief Executive Officer, pursuant to a noncompetition agreement with Viasystems. These interests are described below and may be different from, or in conflict with, your interests as a DDi stockholder. The members of our board of directors were aware of the material facts as to these additional interests, and considered them, when they approved the merger agreement. For purposes of all agreements and arrangements described below, the completion of the merger will constitute a change in control.

Our directors and executive officers are entitled to certain equity acceleration benefits in connection with the merger, as described below in “The Merger—Interests of DDi’s Executive Officers and Directors in the Merger—Treatment of Equity Awards Held by Our Directors and Executive Officers” on page 39.

The employment arrangements of Messrs. Slomsky, Mathews and Barnes with DDi will remain in effect following the merger. In accordance with the terms of their existing employment agreements with DDi, certain executive officers of DDi may be entitled to severance payments in connection with the merger if their employment is terminated as a result of the merger.

Mr. Williams will receive severance payments in accordance with the terms of his existing employment agreement with DDi. Mr. Williams has entered into a letter agreement with DDi requiring that, upon completion of the merger, his severance payments will be deposited in trust to be distributed to him following a six-month delay that is required by law to avoid additional taxes. In addition, Mr. Williams has entered into a non-competition and non-solicitation agreement with Viasystems that will become effective upon the closing of the merger.

Viasystems has agreed to cause the surviving corporation, to the fullest extent permitted by applicable law or contract, to honor all of our obligations to indemnify and hold harmless each person who is now, or has been at any time prior to the date of the merger agreement or who becomes prior to the effective time of the merger an officer or director of us or any of our subsidiaries as provided in our certificate of incorporation or bylaws, or the applicable charter documents of our subsidiary, in each case, as in effect on the date of the merger agreement, or pursuant to any other agreements in effect on the date of the merger agreement, including provisions relating to the advancement of expenses incurred in the defense of any action or as permitted under applicable law.

Viasystems’ obligation to indemnify and hold harmless such persons will survive the merger and will remain in full force and effect for a period of not less than six years after the effective time of the merger. During such period, Viasystems will guarantee the obligations of the surviving corporation with respect to any and all amounts payable in connection with its indemnification and other obligations with respect to such persons.

Viasystems has agreed to obtain, or cause the surviving corporation to obtain, prior to the effective time of the merger a “tail” officers’ and directors’ liability insurance policy, which by its terms shall survive the merger and shall provide such directors and officers with coverage for not less than six years following the effective time of the merger on terms and conditions no less favorable than the terms of our current directors’ and officers’ liability insurance policy in respect of actions or omissions of such officers and directors prior to the effective time of the merger in their capacities as such, subject to certain limitations.

Financing Arrangements (page 61)

by the merger agreement and has agreed to use its reasonable best efforts to obtain and effectuate the debt financing contemplated by its commitment letter on the terms set forth therein. However, Viasystems (or one of its affiliates) may instead, or in addition, complete a debt securities financing, bank loan financing or other debt financing with net cash proceeds that will replace amounts that were to be provided under the bridge loan pursuant to the commitment letter and that were required for the transactions contemplated by the merger agreement. Viasystems and merger sub are not required to consummate the merger before the earlier of (i) the consummation of such debt financing and (ii) August 15, 2012 (or September 15, 2012 under certain conditions in which matters related to antitrust laws prevent the closing at August 15, 2012).

Except to the extent Viasystems (or one of its affiliates) has completed such a debt offering, Viasystems agrees to notify us as soon as reasonably practicable if, at any time prior to the closing date, (i) its commitment letter shall expire or be terminated for any reason, (ii) any financing source that is a party to its commitment letter notifies Viasystems that such source no longer intends to provide financing to Viasystems or (iii) for any reason Viasystems no longer believes in good faith that it will be able to obtain the bridge loan financing substantially on the terms described in its commitment letter.

No Solicitation of Acquisition Proposals (page 61)

We have agreed that we will not, and will cause our subsidiaries and our directors, officers, employees, financial advisors, attorneys, accountants or other advisors, agents or representatives not to, directly or indirectly:

•

solicit, initiate, cause, knowingly facilitate or encourage (including by way of furnishing information) the submission of any inquiries, proposals or offers or any other efforts or attempts that constitute or may reasonably be expected to lead to any acquisition proposal (as defined in the merger agreement and described below under the heading “The Merger Agreement—Board Recommendation” beginning on page 63); or

•

engage in any discussions or negotiations with respect to any acquisition proposal or otherwise cooperate with or assist or participate in, or knowingly facilitate or encourage, any such inquiries, proposals, discussions or negotiations, or resolve to or publicly propose to take any of the foregoing actions.

Despite these general prohibitions, at any time prior to the effective time of the merger and subject to the conditions described below, in response to a written bona fide acquisition proposal, we may:

•

furnish confidential information with respect to us and our subsidiaries to the person making a bona fide written acquisition proposal, provided that we may only furnish such information pursuant to a confidentiality agreement which (i) contains terms that are no less restrictive than those contained in the confidentiality agreement between us and Viasystems, (ii) expressly permits us to comply with the no-solicitation provisions of the merger agreement and (iii) does not include any provision calling for an exclusive right to negotiate with us prior to the termination of the merger agreement; and

•

participate in discussions or negotiations with the person making such acquisition proposal regarding such acquisition proposal.

We may only take these actions if:

•

a breach by us of the no-solicitation provisions of the merger agreement did not contribute to the making of such acquisition proposal;

•

our board of directors determines in good faith, after consultation with our financial advisors and outside counsel, that such acquisition proposal constitutes or is reasonably likely to lead to a superior proposal (as defined in the merger agreement and described below under the heading “The Merger Agreement—Board Recommendation” beginning on page 63);

•

after consultation with our outside counsel, our board of directors determines in good faith that failure to take such action would constitute a breach by our board of directors of its fiduciary duties to our stockholders under applicable law;

•

we promptly (and in any event within 24 hours) provide to Viasystems notice of our intention to enter into an acceptable confidentiality agreement (as described above) with such person;

•

we promptly (and in any event within 24 hours) provide to Viasystems any and all non-public information delivered to such person which was not previously provided to Viasystems;

•

we promptly (and in any event within 24 hours) notify Viasystems, orally and in writing, in the event that we or any of our subsidiaries or directors, officers, employees, financial advisors, attorneys, accountants or other advisors, agents or representatives receives:

•

any acquisition proposal or indication by any person that it is considering making an acquisition proposal;

•

any request for non-public information in contemplation of an acquisition proposal relating to us or any of our subsidiaries; or

•

any inquiry or request for discussions or negotiations regarding any acquisition proposal;

•

we provide Viasystems promptly (and in any event within 24 hours) with the identity of such person and a copy of such acquisition proposal, indication, inquiry or request (or, where such acquisition proposal is not in writing, a written description of our understanding of the material terms and conditions of such acquisition proposal, indication, inquiry or request), including any modifications thereto;

•

we keep Viasystems informed (orally and in writing) on a current basis (and in any event no later than 24 hours after the occurrence of any material changes, developments, discussions or negotiations) of the status of any acquisition proposal, indication, inquiry or request (including the material terms and conditions thereof and of any material modification thereto), and any developments, discussions and negotiations, including furnishing copies of any written inquiries, correspondence and draft documentation, and written summaries of any material oral inquiries or discussions;

•

we promptly (and in any event within 24 hours) notify Viasystems orally and in writing if we determine to begin providing information or to engage in discussions or negotiations concerning an acquisition proposal and do not begin providing such information or engaging in such discussions or negotiations prior to providing such notice;

•

we do not, and cause our subsidiaries and directors, officers, employees, financial advisors, attorneys, accountants or other advisors, agents or representatives not to, enter into any contract with any person subsequent to the date of the merger agreement that would restrict our ability to provide such information relating to us or any of our subsidiaries to Viasystems; and

•

we (i) do not, and cause our subsidiaries not to, terminate, waive, amend or modify any provision of, or grant permission or request under, any standstill or confidentiality agreement to which we or any of our subsidiaries is or becomes a party and (ii) use, and shall cause our subsidiaries to use, reasonable best efforts to enforce the provisions of any such agreement.

The Voting Agreements (page 77)

In connection with the execution of the merger agreement, certain of our directors, executive officers and stockholders, each in such person’s capacity as a stockholder, entered into a voting agreement with Viasystems (collectively referred to as the voting agreements) pursuant to which each agreed, among other things, to vote such person’s shares of our common stock in favor of the adoption of the merger agreement and against any alternative acquisition proposal, or our reorganization, recapitalization, liquidation or winding up, and against any action that would frustrate the purposes of, or prevent or delay the consummation of the transactions contemplated by the merger agreement. The voting agreements (other than the voting agreement signed by Bryant R. Riley) provide that the stockholders signing the voting agreements will not sell their shares of our common stock prior to the consummation of the merger (or earlier termination of the merger agreement). If the merger agreement terminates in accordance with its terms, these voting agreements will also terminate. Not including the shares held by Mr. Riley, approximately 22.6% of the outstanding shares of our common stock on March 30, 2012 were subject to the voting agreements. Mr. Riley held approximately 3.2% of the outstanding shares of our common stock on March 30, 2012.

Termination of the Merger Agreement (page 70)

The merger agreement may be terminated, and the transactions contemplated under the merger agreement may be abandoned, whether before or after obtaining our stockholders’ approval, under the following circumstances:

•

by our, Viasystems’ and merger sub’s mutual written consent;

•

by either Viasystems or us if:

•

the merger is not consummated by August 15, 2012 (or September 15, 2012 under certain conditions in which matters related to antitrust laws prevent the closing at August 15, 2012), but

this right to terminate the merger agreement will not be available to any party whose failure to act to fulfill any obligation under the merger agreement caused the failure of the effective time to occur on or before such date; provided, that if on such date, the conditions to closing relating to antitrust consents or the absence of injunctions or restraints (but only if such restraint or injunction is attributable to an antitrust law) shall not have been fulfilled, but all other conditions to closing shall be or shall be capable of being fulfilled, then either we or Viasystems may extend such date to September 15, 2012 upon written notice to the other parties hereto;

•

if any governmental authority shall have (i) enacted, issued, promulgated or enforced any law that makes consummation of the merger illegal or otherwise prohibited or (ii) enacted, issued, promulgated, enforced or entered any order which has the effect of making the consummation of the merger illegal or otherwise preventing or prohibiting consummation of the merger;

•

if the stockholders’ meeting (including any adjournment or postponement thereof) has concluded, our stockholders have voted and the stockholders’ approval was not obtained; provided, however, that the right to terminate the merger agreement shall not be available to us if we have not materially complied with certain of our covenants relating the conduct of our business and our proxy statement and stockholders’ meeting;

•

by us if:

•

there shall have been a breach or inaccuracy of any representation, warranty, covenant or agreement on the part of Viasystems or merger sub contained in the merger agreement, which breach or inaccuracy (i) would reasonably be expected to prevent Viasystems or merger sub from consummating the merger in accordance with the terms of the merger agreement and (ii) is incapable of being cured or has not been cured prior to August 15, 2012 (or September 15, 2012 under certain conditions in which matters related to antitrust laws prevent the closing at August 15, 2012); provided, however, that we are not then in material breach of any representation, warranty or covenant under the agreement; or

•

we enter into a definitive agreement with respect to a superior proposal subject to the requirements of the no solicitation provisions of the merger agreement described under “The Merger Agreement—No Solicitation of Acquisition Proposals” beginning on page 61; provided, however, we must concurrently enter into the alternative acquisition agreement;

•

by Viasystems if:

•

any effects, events, occurrences, developments, state of facts or changes has occurred that, individually or in the aggregate, have had or would reasonably be expected to have a material adverse effect on us; provided, however, that neither Viasystems nor merger sub is then in material breach of any representation, warranty or covenant under the merger agreement;

•

there has been a breach or inaccuracy of any representation, warranty, covenant or agreement on our part contained in the merger agreement, which breach or inaccuracy would (i) give rise to the failure of the conditions to closing relating to our stockholders’ adoption of the merger agreement or antitrust consents and (ii) is incapable of being cured or has not been cured prior to August 15, 2012 (or September 15, 2012 under certain conditions in which matters related to antitrust laws prevent the closing at August 15, 2012); provided, however, that neither Viasystems nor merger sub is then in material breach of any representation, warranty or covenant under the merger agreement;

•

our board of directors has made an adverse recommendation change;

•

our board of directors or any committee thereof has not rejected any acquisition proposal within seven days of the making thereof (including, for these purposes, by taking no position with respect to the acceptance by our stockholders of a tender offer or exchange offer, which shall constitute a failure to reject such acquisition proposal);

•

our board of directors or any committee thereof has failed, pursuant to Rule 14e-2 promulgated under the Securities Exchange Act or otherwise, to publicly reconfirm our board of directors’ recommendation of the merger within four days after receipt of a written request from Viasystems that it do so if such request is made following the making by any person of an acquisition proposal; or

•

we have violated or breached in any material respect any of our obligations in the no solicitation provisions of the merger agreement described under “The Merger—No Solicitation of Acquisition Proposals” beginning on page 61.

Termination Fee, Reverse Breakup Fee and Expenses (page 71)

We have agreed to pay Viasystems $9.8 million upon or following the termination of the merger agreement under certain circumstances. We have also agreed that if we receive a written bona fide acquisition proposal and, following the receipt of such a proposal, our stockholders do not approve the merger, then we will reimburse Viasystems’ expenses (not to exceed $8 million) related to the transactions contemplated by the merger agreement. Any such expense reimbursement payment will be credited against the $9.8 million termination fee.

Additionally, Viasystems has agreed to pay us a reverse breakup fee of $15.4 million upon the termination of the merger agreement under certain circumstances.

Except as expressly set forth in the merger agreement, all expenses incurred in connection with the merger agreement will be paid by the party incurring such expenses, whether or not the merger is consummated.

Regulatory Matters (page 50)

The HSR Act prohibits us from completing the merger until we have furnished certain information and materials to the Antitrust Division of the Department of Justice and the Federal Trade Commission and the required waiting period has expired or been terminated. The parties expect to file their respective notification and report forms pursuant to the HSR Act with the Antitrust Division of the U.S. Department of Justice and the Federal Trade Commission on the week of April 16, 2012, but there is no assurance as to the outcome of the reviews.

Litigation Related to the Merger (page 50)

A total of three complaints challenging the merger have been filed by plaintiffs seeking to represent a class of DDi shareholders. Two complaints have been filed in the Superior Court, Orange County, State of California, and one has been case filed in the Court of Chancery of the State of Delaware. The complaints allege, among other things, that (i) that the members of our board of directors violated the fiduciary duties owed to stockholders by approving the merger agreement, (ii) that the members of our board of directors engaged in an unfair process and agreed to a price that allegedly fails to maximize value for stockholders and (iii) that DDi, Viasystems and merger sub aided and abetted the board members’ alleged breach of fiduciary duties. The complaints seek, among other things, to enjoin the transaction until corrective actions are taken, as well as to award to plaintiffs the costs and disbursements of the action, including attorneys’ fees and experts’ fees. We, the members of our board of directors and each of the other named defendants intend to defend ourselves vigorously in these actions.

Appraisal Rights (page 43)

Record holders of our common stock as of the record date who do not vote in favor of the merger may elect to pursue their appraisal rights to receive the judicially determined “fair value” of their shares, which could be more or less than, or the same as, the per share merger consideration for the common stock, but only if they comply with the procedures required under Delaware law. For a summary of these Delaware law procedures, see “The Merger—Appraisal Rights” beginning on page 43. An executed proxy that is not marked “AGAINST” or “ABSTAIN” will be voted “FOR” the adoption of the merger agreement and will disqualify the stockholder submitting that proxy from demanding appraisal rights.

A copy of Section 262 of the General Corporation Law of the State of Delaware, or DGCL, is included as Annex E to this proxy statement. Failure to follow the procedures set forth in Section 262 of the DGCL will result in the loss of appraisal rights. We encourage you to read these provisions carefully and in their entirety.

ANY DDI STOCKHOLDER WHO WISHES TO EXERCISE APPRAISAL RIGHTS OR WHO WISHES TO PRESERVE HIS, HER OR ITS RIGHT TO DO SO SHOULD REVIEW ANNEX E CAREFULLY AND SHOULD CONSULT HIS, HER OR ITS LEGAL ADVISOR, SINCE FAILURE TO TIMELY AND FULLY COMPLY WITH THE PROCEDURES SET FORTH THEREIN WILL RESULT IN THE LOSS OF SUCH RIGHTS.

Our common stock is listed on the NASDAQ Global Select Market under the symbol “DDIC.” This table shows, for the periods indicated, the range of intraday high and low per share sales prices for our common stock, and the amount of cash dividends declared per share, as reported on the NASDAQ Global Select Market.

The following table sets forth the closing price per share of our common stock, as reported on the NASDAQ Global Select Market on April 3, 2011, the last full trading day before the public announcement of the merger, and on [ ], the latest practicable trading day before the printing of this proxy statement:

You are encouraged to obtain current market quotations for our common stock in connection with voting your shares of common stock. If the merger is consummated, there will be no further market for our common stock and our common stock will be delisted from the NASDAQ Global Select Market and deregistered under the Securities Exchange Act.

In 2010, our board of directors adopted a cash dividend policy. Cash dividends are discussed quarterly by our board of directors and management. The actual declaration of future cash dividends, and the establishment of record and payment dates, is subject to final determination by our board of directors after its review of our financial performance, expected future operations and earnings, capital requirements and surplus, contractual restrictions, alternative uses of cash, and other factors as our board of directors may deem relevant. In addition, the terms of our revolving credit facility contain certain restrictions on our ability to pay dividends.

Pursuant to the merger agreement, our board is permitted to declare a second quarter dividend of $0.12 per share of our common stock, provided the record date for such dividend is no earlier than June 30, 2012. Should the merger be consummated prior to the record date, this dividend would not be paid. We agreed not to declare, set aside, make or pay any additional dividends without the consent of Viasystems until the earlier of the consummation of the merger or the termination of the merger agreement.

The enclosed proxy is solicited on behalf of the board of directors of DDi for use at the special meeting of stockholders or at any adjournment or postponement thereof.

We will hold the special meeting at DDi’s corporate headquarters, located at 1220 N. Simon Circle, Anaheim, California 92806, at 8:00 a.m., local time, on [ ].

At the special meeting, we will ask the holders of our common stock to (i) adopt the merger agreement, as it may be amended from time to time, (ii) if there are not sufficient votes in favor of adoption of the merger agreement, to adjourn the special meeting to a later date, if necessary or appropriate, to solicit additional proxies and (iii) vote on a proposal with respect to the approval, on an advisory (non-binding) basis, of certain compensation that may be paid or become payable to DDi’s named executive officers in connection with the merger.

Only holders of record of our common stock at the close of business on [ ], the record date, are entitled to notice of, and to vote at, the special meeting. On [ ], the record date, [ ] shares of our common stock were issued and outstanding and held by approximately [ ] holders of record. Holders of record of our common stock on the record date are entitled to one vote per share at the special meeting for each of the proposals to be voted upon.

A quorum of stockholders is necessary to hold a valid special meeting. Under our bylaws, a quorum is present at a meeting if the holders of a majority in voting power of the shares of our common stock issued and outstanding and entitled to vote at the meeting are present in person or represented by proxy. In the event that a quorum is not present at the special meeting, it is expected that the special meeting will be adjourned so that we may solicit additional proxies. For purposes of determining the presence of a quorum, abstentions will be counted as shares present and broker non-votes (where a broker or nominee does not exercise discretionary authority to vote on a matter), if any, will also be counted as shares present.

The adoption of the merger agreement requires the affirmative vote of the holders of a majority of the outstanding shares of our common stock entitled to vote at the special meeting. Adoption of the merger agreement is a condition to the closing of the merger.

The affirmative vote of a majority of the shares of our common stock present in person or represented by proxy and entitled to vote at the special meeting is required to approve the proposal to adjourn the special meeting, if necessary or appropriate, to solicit additional proxies in the event there are not sufficient votes in favor of adoption of the merger agreement at the time of the special meeting, whether or not a quorum is present. The affirmative vote of a majority of the shares of our common stock present in person or represented by proxy and entitled to vote at the special meeting and casting a vote for or against such matter is required to approve, on an advisory (non-binding) basis, certain compensation that may be paid or become payable to DDi’s named executive officers in connection with the merger, provided that a quorum is present.

At the close of business on the record date, our directors and executive officers and their affiliates owned and were entitled to vote shares of our common stock, which represented approximately [ ]% of the shares

of our outstanding common stock on that date. We expect that these directors and executive officers will vote all of their shares of our common stock “FOR” adoption of the merger agreement, “FOR” the proposal to adjourn the special meeting to a later date, if necessary or appropriate, to solicit additional proxies and “FOR” the proposal with respect to an approval, on an advisory (non-binding) basis, of certain compensation that may be paid or become payable to DDi’s named executive officers in connection with the merger.

In connection with the execution of the merger agreement, certain of our directors, executive officers and stockholders entered into voting agreements agreeing to vote in favor of the adoption of the merger agreement. As of March 30, 2012, the record date for the special meeting, these directors, executive officers and stockholders collectively beneficially owned 25.62% of our common stock entitled to vote at the special meeting.

Whether you are a stockholder of record or hold your shares in “street name” through a broker, bank, trustee or other nominee, you may vote your shares in one of the following ways:

At the Special Meeting—If you are a stockholder of record, you may vote in person by attending the special meeting and submitting a ballot. If your shares are held in “street name” through a broker, bank, trustee or other nominee, you may vote in person at the special meeting only if you first obtain a legal proxy from the broker, bank, trustee or other nominee that holds your shares giving you the right to vote the shares. Under a legal proxy, the broker, bank, trustee or other nominee confers all of its legal rights as a record holder to grant proxies or to vote at the special meeting.

You will need proof of ownership of our common stock, as well as a form of personal photo identification, to enter the special meeting. In addition, if your shares are held in street name, you must also present your legal proxy from your broker, bank, trustee or other nominee to be admitted to the special meeting. Even if you plan to attend the special meeting, we recommend that you also vote by mail, telephone or the Internet as described below so that your vote will be counted if you later decide not to attend the special meeting.

By Internet—Stockholders may submit proxies over the Internet. Instructions for doing so are provided along with your proxy card or voting instruction form. If you vote on the Internet, please do not mail in your proxy card. Subject to rules relating to broker non-votes, your Internet vote will authorize the named proxies to vote your shares in the same manner as if you marked, signed and returned your proxy card.

By Telephone—Stockholders may vote by telephone. Instructions for doing so are provided along with your proxy card or voting instruction form. If you vote by telephone, please do not mail in your proxy card. Subject to rules relating to broker non-votes, your telephone vote will authorize the named proxies to vote your shares in the same manner as if you marked, signed and returned your proxy card.

By Mail—Stockholders may sign and date the proxy card or voting instruction form received with this proxy statement and mail it in the enclosed prepaid and addressed envelope. If you mark your choices on the card or voting instruction form, your shares will be voted as you instruct.

All shares represented by properly executed proxies received in time for the special meeting will be voted at the special meeting in accordance with the instructions of the stockholder. Properly executed proxies that do not contain voting instructions will be voted “FOR” the adoption of the merger agreement, “FOR” the proposal to adjourn the special meeting to a later date, if necessary or appropriate, to solicit additional proxies and “FOR” the proposal with respect to an approval, on an advisory (non-binding) basis, of certain compensation that may be paid or become payable to DDi’s named executive officers in connection with the merger, provided that no proxy that is specifically marked “AGAINST” the proposal to adopt the merger agreement will be voted “FOR” the adjournment proposal or the proposal regarding merger-related executive compensation unless it is specifically marked “FOR” the adjournment proposal and/or “FOR” the proposal regarding merger-related executive compensation.

If you do not return your broker’s, bank’s, trustee’s or other nominee’s voting form, provide voting instructions via the Internet or telephone through your broker, bank, trustee or other nominee, if possible, or attend the special meeting and vote in person with a proxy from your broker or nominee, it will have the same effect as if you voted “AGAINST” the adoption of the merger agreement.

If you have sent a proxy directly to DDi, you may revoke your proxy and change your vote irrespective of the method (i.e., Internet, telephone or mail) by which you originally voted by delivering a later-dated proxy or by voting at the special meeting. The later-dated proxy may be delivered by Internet, telephone or mail and need not be delivered by the same means used in delivering the to-be-revoked proxy. You may do this at a later date or time by:

If you are a registered stockholder, you may obtain a new proxy card by contacting the Corporate Secretary, DDi Corp., 1220 N. Simon Circle, Anaheim, California 92806, telephone (714) 688-7200.

Our board of directors has unanimously approved the merger agreement and determined that the merger agreement and the merger are fair to and advisable and in the best interests of DDi and its stockholders. Our board of directors unanimously recommends that DDi stockholders (i) vote “FOR” the proposal to adopt the merger agreement, (ii) vote “FOR” the proposal to adjourn the special meeting to a later date, if necessary or appropriate, to permit the solicitation of additional proxies in the event there are not sufficient votes in favor of adoption of the merger agreement at the time of the special meeting and (iii) vote “FOR” the proposal with respect to an approval, on an advisory (non-binding) basis, of certain compensation that may be paid or become payable to DDi’s named executive officers in connection with the merger.

Stockholders that abstain from voting on a particular matter and shares held in “street name” by brokers or nominees who indicate on their proxies that they do not have discretionary authority to vote such shares as to a particular matter will not be counted as votes in favor of such matter. For purposes of determining the presence of a quorum, abstentions will be counted as shares present and broker non-votes (where a broker or nominee does

not exercise discretionary authority to vote on a matter), if any, will also be counted as shares present. Abstentions and broker non-votes will have (i) the same effect as votes “AGAINST” the adoption of the merger agreement, (ii) the same effect as votes “AGAINST” the approval of the proposal to adjourn the special meeting to a later date, if necessary or appropriate, to solicit additional proxies, whether or not a quorum is present and (iii) no effect on the approval of the proposal to approve, on an advisory (non-binding) basis, certain compensation that may be paid or become payable to DDi’s named executive officers in connection with the merger, provided that a quorum is present.

Adjournments or postponements may be made for the purpose of, among other things, soliciting additional proxies. Any adjournment may be made from time to time with the approval of the affirmative vote of a majority of the shares of our common stock present in person or represented by proxy and entitled to vote at the special meeting, whether or not a quorum is present. We are not required to notify stockholders of any adjournment of less than 30 days if the time and place of the adjourned meeting are announced at the meeting at which the adjournment is taken, unless after the adjournment a new record date is fixed for the adjourned meeting.

In addition, at any time prior to convening the special meeting, the special meeting may be postponed without the approval of our stockholders. If postponed, we will publicly announce the new meeting date.

At any adjourned or postponed meeting, DDi may transact any business that it might have transacted at the original meeting, provided that a quorum is present at such adjourned or postponed meeting. Proxies submitted by our stockholders for use at the special meeting will be used at any adjournment or postponement of the meeting. References to the special meeting in this proxy statement are to such special meeting as adjourned or postponed.

The expenses of soliciting proxies for the special meeting are to be paid by DDi. Solicitation of proxies may be made by means of personal calls upon, or telephonic, telegraphic or electronic communications with, stockholders or their personal representatives by directors, officers, employees and consultants of DDi who will not be specially compensated for such services. Although there is no formal agreement to do so, we may reimburse banks, brokerage houses and other custodians, nominees and fiduciaries for their reasonable expenses in forwarding this proxy statement to stockholders whose common stock is held of record by such entities.

We have also engaged MacKenzie Partners, Inc. to assist in the solicitation of proxies for the special meeting, and we estimate that we will pay them a fee of approximately $10,000, and will reimburse them for reasonable administrative and out-of-pocket expenses incurred in connection with this solicitation. In addition, our arrangement with MacKenzie Partners, Inc. obligates us to indemnify it for certain liabilities that could arise in connection with its solicitation of proxies on our behalf.

A list of stockholders of record entitled to vote at the special meeting will be available at the special meeting. It also will be available for ten business days prior to the special meeting, between the hours of 9 a.m. and 4 p.m., Pacific Time, at the office of the Corporate Secretary, DDi Corp., 1220 N. Simon Circle, Anaheim, California 92806. A stockholder of record may examine the list for any legally valid purpose related to the special meeting.

Victor Merger Sub Corp., a Delaware corporation and wholly-owned subsidiary of Viasystems, was organized solely for the purpose of entering into the merger agreement and completing the merger and the other transactions contemplated by the merger agreement. Merger sub’s principal executive offices are located at 101 South Hanley Road, St. Louis, Missouri 63105 and its telephone number is (314) 727-2087. Merger sub has not conducted any business operations other than in connection with the transactions contemplated by the merger agreement.

Upon consummation of the merger, merger sub will cease to exist, and DDi will continue as the surviving corporation under the name Viasystems North America, Inc.

The following discussion summarizes the material terms of the merger. We urge you to read carefully the merger agreement, which is attached as Annex A to this proxy statement.

Since 2006, our management has pursued a growth strategy which included, among other initiatives, extending our service offerings by seeking to establish low-cost manufacturing capability into China and Southeast Asia. We have pursued this strategy by way of a China-based acquisition or a business combination with a strategic partner with manufacturing assets in China. This growth strategy was aimed at addressing our management’s concern that in order to stay competitive in the increasingly global PCB market, we would need to be able to address the needs of our customers with global requirements, particularly with respect to lower mix, higher volume production. As we pursued this strategy, it became apparent to our management and board of directors that successfully completing a meaningful acquisition in China would require DDi to finance a transaction, which would result in substantial additional debt or dilution to our existing stockholders.

In mid-2010, our board of directors decided that it would be beneficial to perform a market check of our strategic alternatives to help inform the board as it evaluated potential business combinations, including with companies with manufacturing assets in China and Southeast Asia. On July 30, 2010, we engaged Jefferies & Company, Inc., which we refer to as Jefferies, and Mooreland Partners, LLC, which we refer to as Mooreland, as our financial advisors.

Between August and September 2010, at the request of our board of directors Jefferies and Mooreland began a market check and approached 56 potential counterparties including 15 strategic counterparties and 41 financial sponsors to solicit their potential interest in acquiring or merging with DDi. Confidential information was provided to 27 parties that showed initial interest, including Viasystems.

Between August and October 2010, with the assistance of Jefferies and Mooreland, we held 11 management meetings or calls with qualified counterparties. As a result, we received six written indications of interest in October 2010 with offers ranging from $9.00 to $11.75 per share. The offers included proposals consisting of all cash, all stock and combinations of cash and stock. A strategic counterparty submitted the high bid valued between $11.25 and $11.75 per share, in stock and cash, and Viasystems submitted the low bid consisting of all stock estimated to be valued between $9.00 and $9.50 per share.

In October 2010, after thoughtful consideration and further discussions, our board of directors decided that none of the indications of interest was sufficiently compelling. In addition, two strong potential counterparties, including Viasystems, expressed to us that the timing of a transaction was not ideal and that they might be more interested in exploring a transaction at some point in the future. Because of this limited interest from key counterparties, we instructed Jefferies and Mooreland in October 2010 to discontinue any active dialogue or marketing efforts.

Between October 2010 and January 2012, DDi’s board and management continued to constantly evaluate and pursue our strategic alternatives, including pursuing potential acquisitions or business combinations with strategic partners that have manufacturing assets in China and Southeast Asia. As part of that effort, between 2006 and 2012, Mikel Williams, our Chief Executive Officer, met, on separate occasions, with representatives of three institutional investors which held significant positions in Viasystems common stock. At the meetings, the parties discussed the potential of a business combination of Viasystems and DDi and the potential synergies that could be attained therefrom. After January 2012, there was no further contact between the Viasystems institutional shareholders and Mr. Williams.

In early February 2012, David Sindelar, the Chief Executive Officer of Viasystems, contacted Mr. Williams to request a meeting to discuss the possibility of a merger of DDi and Viasystems. Mr. Williams requested more specific information about Viasystems’ proposed agenda, form of consideration and valuation prior to agreeing to schedule a meeting.

On February 17, 2012, Mooreland received a telephone call from Stifel Nicolaus Weisel, which we refer to as Stifel, financial advisor to Viasystems, expressing Viasystems’ serious interest in acquiring us in a friendly transaction. Mooreland agreed to speak to us and convey Viasystems’ intentions. Stifel indicated that a more formal letter would be forthcoming.

Later that day, Mooreland contacted Mr. Williams to relay the message from Stifel and to discuss any response.

On February 21, 2012, as indicated by Stifel, Viasystems sent us a letter formally expressing their “strong interest to engage in discussions regarding a potential merger.” A copy of the letter was provided to all members of DDi’s board of directors.

On February 22, 2012, the finance committee of our board of directors held a call to discuss the letter. Pursuant to its charter, the finance committee of our board of directors has authority to review and make recommendations to the board regarding any merger and acquisitions activities of DDi. The finance committee decided that DDi should respond to the letter by asking Viasystems to provide specifics with respect to the proposed transaction, including details with respect to purchase price, deal structure, financing, process and timing. Jefferies and Mooreland were asked to communicate this response to Viasystems through Viasystems’ financial advisor, which they did.

On February 27, 2012, Viasystems sent Mr. Williams a preliminary non-binding proposal letter proposing an all cash purchase price of $12.50 per share.

On February 28, 2012, the finance committee of our board of directors held a call to discuss the offer letter and formulate a response to Viasystems. The finance committee of our board of directors agreed on three major action items: (i) to convey to Viasystems that its offer was interesting but inadequate and to express further interest in discussing Viasystems’ offer; (ii) to schedule a meeting on March 2, 2012 with Mr. Williams and Mr. Sindelar and the parties’ respective financial advisors in order to review potential synergies that could result from a transaction and support our request for a higher offer price; and (iii) to have Jefferies and Mooreland contact four potential strategic buyers, which we refer to as Company A, Company B, Company C and Company D, who had previously shown interest during the market check in 2010 (or in subsequent dialogues), which were determined to be the most likely to have continued interest in, and the ability to complete, a strategic transaction, and which could be approached without unnecessary risk of disclosure. In the context of evaluating the Viasystems letter, the finance committee discussed the other alternatives available to us to maximize stockholder value by growing the business both by taking market share and by pursuing potential acquisitions.

Also on February 28, 2012 the chairman of the finance committee of our board of directors requested that Jefferies, or one of Jefferies’ affiliates, propose to make available acquisition financing to Viasystems in connection with the potential acquisition of DDi. The request by the chairman of the finance committee was subsequently ratified by the entire finance committee on March 16, 2012. The finance committee of our board of directors believed that Jefferies’ involvement may facilitate favorable financing terms for Viasystems, which, in turn, would enable Viasystems to offer a higher purchase price, On or about March 19, 2012, representatives of Jefferies’ leveraged finance group met with Viasystems to discuss providing such acquisition financing. Subsequently, however, Viasystems decided not to use Jefferies in connection with such acquisition financing and no further contact between Viasystems and Jefferies was made concerning Jefferies’ provision of acquisition financing.

During the first two days of March 2012, Jefferies and Mooreland began contacting the four other strategic parties in order to assess their interest in a potential business combination with us. One of the additional

companies, Company A, expressed immediate interest and a meeting with our management was scheduled for March 5, 2012.

On March 2, 2012, Mr. Williams and representatives of Jefferies and Mooreland met in St. Louis with Viasystems’ senior executives, including Mr. Sindelar, and Visasystems’ financial advisors. The purpose of the meeting was to attempt to persuade Viasystems to increase its offer based upon the current and projected value of our business.

On March 2, 2012, one of the additional strategic counterparties, Company B, indicated that they had decided to pass on the opportunity after discussing it internally.

On March 3, 2012, the finance committee of our board of directors and our financial advisors held a conference call to consider a response to Viasystems’ offer. The finance committee of our board of directors agreed and directed our financial advisors to propose to Viasystems a $14.00 per share counteroffer along with an offer of an exclusivity period through March 30, 2012 to negotiate a definitive agreement and a 4% breakup fee in an effort to induce Viasystems to agree to our higher counteroffer.

On March 5, 2012, another of the strategic counterparties approached by Jefferies and Mooreland, Company C, indicated that after review, they were going to pass on the opportunity to pursue a transaction with us.

On March 5, 2012, our management held a meeting with Company A, which expressed continued interest and stated they had consulted with their board of directors, financial advisors and potential sources of capital regarding a potential business combination and were still assessing the attractiveness from its perspective of such a transaction.

On March 5, 2012, in response to our $14.00 per share counteroffer communicated on March 3, 2012, Viasystems verbally responded with an increased non-binding bid of $12.75 per share. Viasystems also requested an exclusivity period until March 31, 2012 to perform their due diligence investigation and negotiate a definitive agreement.

On March 6, 2012, our board of directors and financial advisors met to consider a response to the latest Viasystems offer. At that meeting, our board and finance committee determined to engage Paul Hastings LLP, which we refer to as Paul Hastings, as external counsel to advise our board and finance committee through the process of evaluating any potential interest by Viasystems and related matters.

Our board and finance committee then discussed the request by Viasystems for an exclusivity period for negotiations during which we would, among other things, not be able to discuss an acquisition with any other party. Jefferies and Mooreland briefed the board on the efforts to contact other potential strategic buyers. At the end of a detailed discussion and after consulting with its financial and legal advisors, including a discussion with Jefferies and Mooreland who reviewed with the board their preliminary financial analysis of Viasystems’ indication of interest, our board believed that the analysis indicated that Viasystems’ current proposal was within the range of values that would be fair to our stockholders. For reference, DDi’s closing stock price on March 6, 2012 was $10.88. The board decided that we should continue negotiations with Viasystems and seek to improve upon the current proposal. The board directed Jefferies and Mooreland to communicate to the financial advisors to Viasystems that our board was prepared to move forward with four weeks of exclusive due diligence and negotiations if Viasystems raised its indication of interest price to $13.50 per share, but that we would only agree to such an exclusivity period if Viasystems agreed that the definitive agreement contained either a fiduciary out or a go shop provision and there were no unusual closing conditions that Viasystems anticipated requesting in connection with a definitive agreement. Our board then delegated authority to the finance committee of the board to continue negotiations with Viasystems and act on such matters. Our board also discussed additional steps required if it were to receive an indication of interest from other interested parties.

On March 6, 2012, Company A contacted Mooreland to communicate that, after further consideration, they had concluded that they would not proceed with their investigation of an acquisition.

On March 7, 2012, Company D contacted Mooreland to communicate that, after further consideration, they had concluded that they would not proceed with their investigation of an acquisition.

On March 7, 2012, Viasystems verbally responded to our $13.50 per share offer communicated on March 6, 2012 with a revised non-binding bid of $13.00 per share. Stifel indicated on behalf of Viasystems that $13.00 per share was their “best and final” bid, and that Viasystems was prepared to walk away from the deal if this offer was not satisfactory. The finance committee of our board of directors met on March 7, 2012 to evaluate Viasystems response. Still believing that the transaction would be significantly financially beneficial to both parties, the finance committee requested that Mr. Williams call Mr. Sindelar to relay the finance committee’s proposal of a $13.25 per share counteroffer based upon the mutual benefits that could be attained through the transaction. Mr. Williams reported later that afternoon to a reconvened finance committee that Viasystems indicated that it would not revise its $13.00 cash offer per share.

On March 8, 2012, after multiple additional rounds of negotiations with Viasystems and having received word that all four potential alternative buyers had declined to pursue the opportunity, the finance committee of our board of directors determined that Viasystems’ revised offer of $13.00 per share was adequate to justify exploring a potential transaction with Viasystems on an exclusive basis. It was noted that the offer price represented a meaningful premium to the current stock price as well as a premium to the 52 week and 5 year high prices. The finance committee also considered the implied multiples resulting from the offer of $13.00 per share. Based on these factors, the finance committee of our board of directors authorized the company to enter an exclusivity agreement with Viasystems with the goal of reaching a definitive agreement. After negotiating the terms of the exclusivity agreement, the parties signed a 30-day agreement on March 12, 2012 and the parties began their confirmatory due diligence. In connection with the finance committee’s and the board’s discussions as to whether to enter into exclusive negotiations with Viasystems, the committee discussed whether to consider a sale at the present time in light of DDi’s business prospects and operating environment and, after consulting with its financial and legal advisors, determined that it was prepared to consider a sale now at an attractive price. For reference, DDi’s closing stock price on March 8, 2012 was $11.44. On March 8, 2012, after multiple additional rounds of negotiations with Viasystems, and after having received word that all four potential alternative buyers had declined to pursue a transaction with us, our board of directors determined that Viasystems’ revised offer of $13.00 per share was adequate to justify exploring a potential transaction on an exclusive basis with Viasystems. It was noted that the offer price represented a meaningful premium to the current stock price as well as a premium to our stock’s 52-week and 5-year high prices. Based on these factors, our board of directors authorized the company to enter into an exclusivity agreement with Viasystems with the goal of reaching a definitive agreement within that exclusivity period. After negotiating the terms of the exclusivity agreement, the parties signed an exclusivity agreement with a 30-day exclusivity period on March 12, 2012. Immediately thereafter, Viasystems began its confirmatory due diligence review.

On March 12 and 13, 2012, the management teams and key employees from both companies, together with their respective legal and financial advisors met in Los Angeles, California for diligence meetings. Representatives from Viasystems’ potential financing sources also attended.

On March 15, 2012, Jones Day, legal counsel to Viasystems, sent Paul Hastings an initial draft of the merger agreement relating to the proposed acquisition of our company by Viasystems, which we refer to as the merger agreement. From March 15, 2012 until April 3, 2012, we and Viasystems, and our respective legal counsel, engaged in negotiations regarding the terms of the merger agreement.

On March 16, 2012, the finance committee of our board of directors held a meeting to discuss the status of the negotiations. Mr. Williams reported on Viasystems’ due diligence progress. Paul Hastings provided an update

on open issues regarding the draft merger agreement, including the termination provisions, the company material adverse effect clause and compensation matters.

On March 26, 2012, our finance committee of the board held a meeting to discuss the status of negotiations. Mr. Williams reported on Viasystems’ due diligence progress, namely the completion of Phase I environmental assessments of DDi’s manufacturing locations and tours of two of seven sites. Paul Hastings provided an update of open legal issues, including unresolved outstanding issues relating to termination and expense reimbursement.

On March 27, 2012, our board held a meeting to provide an update relating to Viasystems’ due diligence progress. Mr. Williams reported that Viasystems had completed Phase I environmental assessments of our manufacturing locations and that four of the seven scheduled site tours were complete. Mr. Williams also stated that the DDi management team continued to respond to due diligence requests and provide information to Viasystems and its advisors through the virtual data room. He stated that he was not aware of any significant due diligence issues that would be problematic for the transaction. At the same meeting, Mr. Williams provided the board with an update with respect to the financial performance of our business. Representatives of Jefferies and Mooreland then discussed the recent increase in the market price of our common stock on the NASDAQ Global Select Market.

At that meeting, the board also discussed strategies with representatives of Jefferies and Mooreland for seeking an increased price from Viasystems and whether the transaction was still in the best interests of the corporation and its stockholders. Jefferies stated that the recent increase in the market price for DDi’s common stock and resulting reduction in the transaction premium did not alter the intrinsic value of DDi. Paul Hastings provided a summary of its comments to the merger agreement which were discussed with the board.

The parties and their financial and legal advisors continued to negotiate the proposed terms of a definitive merger agreement. Among the issues that remained unresolved was DDi’s desire to continue to declare dividends post-signing.

On April 1, 2012, our finance committee of the board met. Mr. Williams provided the finance committee with an update with respect to the financial performance of our business. He noted that the business continued to perform in line with DDi’s internal expectations. The finance committee also discussed the current draft of the merger agreement, including the proposed prohibition on DDi’s ability to declare and pay dividends. The finance committee insisted upon retaining the right to continue to pay regularly scheduled quarterly cash dividends until the closing date of the merger. The finance committee instructed Jefferies and Mooreland to convey to Viasystems’ advisors that DDi felt strongly regarding the right to continue to pay cash dividends. The finance committee also was briefed by Paul Hastings relating to issues raised by their review of Viasystems commitment letters as they applied to Viasystems’ proposed financing for the merger transaction.

Following that meeting, Jefferies and Mooreland discussed the dividend issue, as well as all other unresolved issues with Stifel. Later that day, DDi forwarded an amended draft of the merger agreement to Viasystems that included a reverse breakup fee equal to $19.6 million (approximately 7% of the transaction value), a provision allowing DDi to declare a quarterly cash dividend and revisions to Viasystems’ financing covenants which were designed to provide greater assurance related to funding the merger transaction. Paul Hastings also provided comments to Viasystems regarding its bridge financing commitment letter.

Late on April 2, 2012, DDi received an amended draft of the merger agreement which (i) included the right to pay a single cash dividend of $0.12 per share as long as the record date was on or after June 30, 2012 and (ii) provided for a reverse breakup fee in favor of DDi equal to $15.4 million (approximately 5.5% of the transaction value) as liquidated damages in lieu of our right to sue for damages after termination.

On April 3, 2012, Paul Hastings sent proposed revisions to the draft of the merger agreement to Jones Day. Viasystems did not accept these changes and indicated that the current draft of the merger agreement was its final proposal.

Later that day on April 3, 2012, our board of directors held a meeting to review the then current draft of the merger agreement. Representatives of Paul Hastings reviewed, among other things, our representations, warranties and covenants contained in the merger agreement, the circumstances under which Viasystems would not be required to complete the acquisition after entering into the merger agreement, perceived issues related to Viasystems’ financing, and the scope of the situations under which Viasystems would be required to pay the reverse breakup fee. Paul Hastings also reviewed with the board the comments to the merger agreement that Viasystems did not accept.

In the course of reaching its decision to approve the merger agreement without further negotiation, our board of directors considered the following factors: (i) the adequacy of the merger consideration; (ii) Viasystems’ concession that DDi declare and pay a second quarter cash dividend with a record date on or after June 30, 2012; (iii) Viasystems’ success in strengthening the terms of its bank commitment letters, thereby providing further assurances of its ability to finance the transaction; (iv) Viasystems’ concession to pay, under certain circumstances, a reverse breakup fee equal to approximately 5.5% of the transaction value; and (v) future uncertainties in the global printed circuit board business.

On April 3, 2012, our finance committee met to consider, and, if appropriate, recommend to the board for approval, and the board of directors met to consider and, if appropriate, vote to approve the merger with Viasystems. Representatives of Paul Hastings reviewed the proposed terms and conditions of the merger agreement, including our representations, warranties and covenants in the merger agreement, the circumstances under which Viasystems would not be required to complete the acquisition after entering into the merger agreement, the ability of our board to respond to and ultimately accept a superior acquisition proposal, the termination fee payable by us if our board withdrew or gave notice of its intent to withdraw its recommendation of the merger and the circumstances upon which a reverse breakup fee would be payable to us. Also at this meeting, representatives of Jefferies delivered to our board its opinion to the effect that, as of April 3, 2012, and based upon and subject to the various assumptions made, procedures followed, matters considered and limitations on the scope of the review undertaken as set forth in its opinion, the consideration of $13.00 per share of our common stock in cash to be received by holders of shares of our common stock pursuant to the merger agreement was fair, from a financial point of view, to such holders. The full text of the opinion of Jefferies, dated April 3, 2012, is attached to this proxy statement as Annex B and is incorporated by reference in this proxy statement in its entirety. See also, “—Opinion of DDi’s Financial Advisor” beginning on page 29. Representatives of Paul Hastings then reviewed the proposed resolutions to be considered for approval by our board. Following such presentations and upon further review and discussion, our finance committee unanimously recommended and our board unanimously resolved to approve the merger agreement and related matters and resolved to recommend that our stockholders adopt the merger agreement, which is attached hereto as Annex A.

The merger agreement was finalized after the cessation of trading of our common stock on the NASDAQ Global Select Market on April 3, 2012, at which point the merger agreement was signed by the parties. The signing of the merger agreement was publicly announced on April 4, 2012, prior to the opening of trading of our common stock on the NASDAQ Global Select Market.

At a meeting of our board of directors on April 3, 2012, our board of directors unanimously determined that the merger agreement and the merger are fair to and advisable and in the best interests of DDi and its stockholders. Accordingly, our board of directors unanimously approved the merger agreement. Our board of directors unanimously recommends that you vote (i) “FOR” the adoption of the merger agreement, (ii) “FOR” the proposal to adjourn the special meeting to a later date, if necessary or appropriate, to solicit additional proxies in the event there are not sufficient votes in favor of adoption of the merger

agreement at the time of the special meeting and (iii) “FOR” the proposal with respect to an approval, on an advisory (non-binding) basis, of certain compensation that may be paid or become payable to DDi’s named executive officers in connection with the merger.

In the course of reaching its decision to approve the merger agreement, to declare that the merger agreement and the merger are fair to and advisable and in the best interests of DDi and its stockholders and to recommend that DDi’s stockholders vote to adopt the merger agreement and approve the merger and the transactions contemplated by the merger agreement, our board of directors consulted with our senior management and our financial advisors Jefferies and Mooreland. Our board of directors also consulted with outside legal counsel regarding its fiduciary duties and the terms of the merger agreement and related matters. The following discussion includes the material reasons and factors considered by our board of directors in making its recommendation, but is not, and is not intended to be, exhaustive.

Factors considered by our board of directors weighing in favor of the merger included:

Merger Consideration. Our board of directors considered the following with respect to the merger consideration to be received by DDi’s stockholders:

Prospects in Remaining Independent. Our board of directors considered the possibility of continuing to operate DDi as an independent public company, including the perceived risks and uncertainties of remaining an independent public company. In considering the alternative of pursuing growth as an independent company, our board of directors considered the following factors:

Solicitation of Interest. Following receipt of proposed terms for the merger from Viasystems, our board of directors, with the assistance of Jefferies and Mooreland, considered other potential acquirers and solicited interest from other parties with the resources and potential strategic interest to pursue a business combination with DDi. Our board of directors also considered its earlier market check in August and September 2010 of 56 potential counterparties to solicit their interest in engaging in a merger or acquisition.

Opinion of Jefferies. Our board of directors considered the opinion of Jefferies, dated April 3, 2012, to the effect that, as of that date and based upon and subject to the various assumptions made, procedures followed, matters considered and limitations on the scope of the review undertaken as set forth therein, the consideration of $13.00 per share of our common stock in cash to be received by holders of shares of our common stock pursuant to the merger agreement was fair, from a financial point of view, to such holders, as more fully described in “—Opinion of DDi’s Financial Advisor” beginning on page 29.

Financial Forecasts. Our board of directors considered the financial forecasts prepared by DDi’s management and summarized below under “—Financial Forecasts” beginning on page 36. These financial forecasts were also provided to Jefferies for purposes of the opinion described in the preceding paragraph.

Terms of the Merger Agreement. Our board of directors considered the terms and conditions of the merger agreement and the course of negotiations thereof, including:

In the course of its deliberations, our board of directors also considered a variety of risks and factors weighing against the merger, including:

Limitations on DDi’s Business. Our board of directors considered the potential limitations on DDi’s pursuit of business opportunities due to pre-closing covenants in the merger agreement whereby DDi agreed that it will carry on its business in the ordinary course of business consistent with past practice and, subject to specified exceptions, will not take certain actions related to the conduct of its business without the prior written consent of Viasystems.

Cash Transaction. Our board of directors considered that the merger consideration is cash and, as a result, our stockholders will forego any potential future increase in our value that might result from our possible growth, and that income realized as a result of the merger generally will be taxable to our stockholders.

Stockholder Vote. Our board of directors considered the requirement that the merger agreement obligates DDi to submit the merger agreement for adoption by DDi’s stockholders even if our board of directors withdraws its recommendation to our stockholders to adopt the merger agreement.

Termination Fee and Other Alternative Acquirers. Our board of directors considered the possibility that the $9.8 million termination fee payable to Viasystems under the circumstances set forth in the merger agreement might discourage a competing proposal to acquire DDi or reduce the price of any such proposal.

Interests of Directors and Officers. Our board of directors considered the interests that certain of our directors and executive officers may have with respect to the merger in addition to their interests as DDi stockholders generally, as described below and in “—Interests of DDi’s Executive Officers and Directors in the Merger” on page 38.

On April 3, 2012, the executive officers and directors who owned, in the aggregate approximately 22.6% of the outstanding shares of our stock, entered into voting agreements with Viasystems which provided that such officers and directors will vote their shares in favor of the adoption of the merger agreement and will not sell their shares before the closing, or earlier termination, of the merger. Mr. Riley, the remaining director who owns for his own account approximately 3.2% of the outstanding shares of our stock on April 3, 2012, also entered into a similar voting agreement; however, Mr. Riley’s voting agreement does not restrict him from selling his shares at any time.

On April 3, 2012, DDi entered into a letter agreement with Mr. Williams, DDi’s Chief Executive Officer, which we refer to as the letter agreement. The letter agreement provides that if the merger becomes effective, DDi will, immediately prior to the effective time of the merger, irrevocably contribute to a grantor trust, which we refer to as the Trust, the cash severance described in subsections (i), (ii) and (iii) of Section 5(e) of Mr. Williams’ employment agreement with DDi dated April 7, 2008, including interest thereon, that is payable in a lump sum six months after his separation from service if Mr. Williams is DDi (or the surviving corporation) terminates Mr. Williams’ employment without “cause” (as defined in Mr. Williams’ employment agreement with DDi), or Mr. Williams terminates his employment for “good reason” (as defined in Mr. Williams’ employment agreement with DDi).

In addition, on April 3, 2012, Viasystems entered into a noncompetition agreement with Mr. Williams, which we refer to as the noncompetition agreement. The noncompetition agreement provides that, effective upon the consummation of the merger (i) Viasystems will pay Mr. Williams $1.3 million and (ii) for a period of twenty-four months, Mr. Williams will not perform any executive management, technical, design or supervisory services in the United States for certain of DDi’s competitors.

The foregoing discussion is not intended to be exhaustive, but we believe it addresses the material information and principal factors considered by our board of directors in its consideration of the merger.

In light of the variety of factors considered in connection with its evaluation of the merger and the complexity of these matters, our board of directors did not find it practicable to, and did not, quantify or otherwise attempt to assign relative weights to the various factors considered in reaching its determination, and individual directors may have given different weight to different factors. In addition, our board of directors did not reach any specific conclusion with respect to any of the factors or reasons considered. Instead, our board of directors conducted an overall analysis of the factors and reasons described above and determined that, in the aggregate, the potential benefits considered outweighed the potential risks or possible negative consequences of approving the merger agreement and accordingly recommends that our stockholders vote “FOR” the adoption of the merger agreement.

We retained Jefferies to provide us with financial advisory services in connection with the merger and an opinion as to the fairness to holders of shares of our common stock of the consideration to be received by such holders in connection with a possible merger, sale or other strategic business combination. At the meeting of our board of directors on April 3, 2012, Jefferies rendered its opinion to our board of directors to the effect that, as of April 3, 2012 and based upon and subject to the various assumptions made, procedures followed, matters considered and limitations on the scope of the review undertaken as set forth therein, the consideration of $13.00

per share of our common stock in cash to be received by holders of shares of our common stock pursuant to the merger agreement was fair, from a financial point of view, to such holders.

The full text of the written opinion of Jefferies, dated as of April 3, 2012, is attached hereto as Annex B. The opinion sets forth, among other things, the assumptions made, procedures followed, matters considered and limitations on the scope of the review undertaken by Jefferies in rendering its opinion. We encourage you to read the opinion carefully and in its entirety. Jefferies’ opinion was directed to our board of directors and addresses only the fairness, from a financial point of view, of the consideration to be received by holders of shares of our common stock pursuant to the merger agreement as of the date of the opinion. It does not address any other aspects of the merger and does not constitute a recommendation as to how any holder of shares of our common stock should vote on the merger or any matter related thereto. The summary of the opinion of Jefferies set forth below is qualified in its entirety by reference to the full text of the opinion.

In Jefferies’ review and analysis and in rendering its opinion, Jefferies assumed and relied upon, but did not assume any responsibility to independently investigate or verify, the accuracy and completeness of all financial and other information that was supplied or otherwise made available by us to Jefferies or that was publicly available (including, without limitation, the information described above), or that was otherwise reviewed by Jefferies. In its review, Jefferies relied on assurances of our management that our management was not aware of any facts or circumstances that would make such information inaccurate or misleading. In its review, Jefferies did not obtain any independent evaluation or appraisal of any of our assets or liabilities of, nor did Jefferies conduct a physical inspection of any of our properties or facilities. Jefferies was not furnished with any such evaluations or appraisals and did not assume any responsibility to obtain any such evaluations or appraisals.

With respect to the financial forecasts provided to and examined by Jefferies, Jefferies’ opinion noted that projecting future results of any company is inherently subject to uncertainty. We informed Jefferies, however, and Jefferies assumed, that such financial forecasts were reasonably prepared on bases reflecting the best currently available estimates and good faith judgments of our management as to the future financial performance of our company. Jefferies expressed no opinion as to our financial forecasts or the assumptions on which they were made.

Jefferies’ opinion was based on economic, monetary, regulatory, market and other conditions existing and which could be evaluated as of the date of its opinion. Jefferies expressly disclaimed any undertaking or obligation to advise any person of any change in any fact or matter affecting Jefferies’ opinion of which Jefferies became aware after the date of its opinion.

Jefferies made no independent investigation of any legal or accounting matters affecting our company, and Jefferies assumed the correctness in all respects material to Jefferies’ analysis of all legal and accounting advice

given to us and our board of directors, including, without limitation, advice as to the legal, accounting and tax consequences of the terms of, and transactions contemplated by, the merger agreement to our company and our stockholders. In addition, in preparing its opinion, Jefferies did not take into account any tax consequences of the transaction to any holder of our common stock. In rendering its opinion, Jefferies assumed that the final form of the merger agreement would be substantially similar to the last draft reviewed by it. Jefferies also assumed that in the course of obtaining the necessary regulatory or third party approvals, consents and releases for the merger, no delay, limitation, restriction or condition would be imposed that would have an adverse effect on us, Viasystems or the contemplated benefits of the merger.

Jefferies’ opinion was for the use and benefit of our board of directors in its consideration of the merger, and Jefferies’ opinion did not address the relative merits of the transactions contemplated by the merger agreement as compared to any alternative transaction or opportunity that might be available to us, nor did it address the underlying business decision by us to engage in the merger or the terms of the merger agreement or the documents referred to therein. Jefferies’ opinion does not constitute a recommendation as to how any holder of shares of our common stock should vote on the merger or any matter relating thereto. In addition, Jefferies was not asked to address, and its opinion did not address, the fairness to, or any other consideration of, the holders of any class of securities, creditors or other constituencies of our company, other than holders of shares of our common stock. Jefferies expressed no opinion as to the price at which shares of our common stock will trade at any time. Jefferies did not express any view or opinion as to the fairness, financial or otherwise, of the amount or nature of any compensation payable or to be received by any of our officers, directors or employees, or any class of such persons, in connection with the merger relative to the consideration to be received by holders of shares of our common stock. Jefferies’ opinion was authorized by the Fairness Committee of Jefferies & Company, Inc.

In preparing its opinion, Jefferies performed a variety of financial and comparative analyses. The preparation of a fairness opinion is a complex process involving various determinations as to the most appropriate and relevant quantitative and qualitative methods of financial analysis and the applications of those methods to the particular circumstances and, therefore, is not necessarily susceptible to partial analysis or summary description. Jefferies believes that its analyses must be considered as a whole. Considering any portion of Jefferies’ analyses or the factors considered by Jefferies, without considering all analyses and factors, could create a misleading or incomplete view of the process underlying the conclusion expressed in Jefferies’ opinion. In addition, Jefferies may have given various analyses more or less weight than other analyses, and may have deemed various assumptions more or less probable than other assumptions, so that the range of valuations resulting from any particular analysis described below should not be taken to be Jefferies’ view of our company’s actual value. Accordingly, the conclusions reached by Jefferies are based on all analyses and factors taken as a whole and also on the application of Jefferies’ own experience and judgment.

In performing its analyses, Jefferies made numerous assumptions with respect to industry performance, general business, economic, monetary, regulatory, market and other conditions and other matters, many of which are beyond our and Jefferies’ control. The analyses performed by Jefferies are not necessarily indicative of actual values or actual future results, which may be significantly more or less favorable than suggested by such analyses. In addition, analyses relating to the per share value of shares of our common stock do not purport to be appraisals or to reflect the prices at which shares of our common stock may actually be sold. The analyses performed were prepared solely as part of Jefferies’ analysis of the fairness, from a financial point of view, of the consideration of $13.00 per share of our common stock in cash to be received by holders of shares of our common stock pursuant to the merger agreement, and were provided to our board of directors in connection with the delivery of Jefferies’ opinion.

The following is a summary of the material financial and comparative analyses performed by Jefferies in connection with Jefferies’ delivery of its opinion and that were presented to our board of directors on April 3, 2012. The financial analyses summarized below include information presented in tabular format. In order to fully understand Jefferies’ financial analyses, the tables must be read together with the text of each summary. The tables alone do not constitute a complete description of the financial analyses. Considering the data described below

without considering the full narrative description of the financial analyses, including the methodologies and assumptions underlying the analyses, could create a misleading or incomplete view of Jefferies’ financial analyses.

Based upon the approximately 21.7 million shares of our common stock that were outstanding as of April 2, 2012 on a fully diluted basis (calculated using the treasury stock method), Jefferies noted that the consideration of $13.00 per share of our common stock implied an equity value of approximately $282.0 million. After adding indebtedness and subtracting cash and cash equivalents (as of March 31, 2012), resulting in a net cash amount of approximately $13.5 million, Jefferies noted that the consideration of $13.00 per share of our common stock implied an enterprise value of approximately $268.5 million. Jefferies also noted that the consideration of $13.00 per share of our common stock represented a premium of:

In its analysis, Jefferies reviewed the price trading history of shares of our common stock for the three-year period ending April 2, 2012. In addition, Jefferies reviewed the price trading history of shares of our common stock for (i) the one-year period ending April 2, 2012 and (ii) the period commencing on January 2, 2012 and ending April 2, 2012 (representing the 2012 year to date price trading history of shares of our common stock), in each case, separately and in relation to the Standard & Poor’s 500 Index and a composite index consisting of the following companies in the printed circuit board market, which we refer to as the “DDi Selected Comparable Companies”:

This analysis showed that during the one-year period ending April 2, 2012, the trading price of shares of our common stock rose 17.4%, the Standard & Poor’s 500 Index rose 5.6%, and the composite index consisting of the DDi Selected Comparable Companies declined 12.6%, and during the period commencing January 2, 2012 and ending April 2, 2012, the trading price of shares of our common stock rose 29.2%, the Standard & Poor’s 500 Index rose 9.9%, and the composite index consisting of the DDi Selected Comparable Companies rose 19.7%.

Using publicly available information and information provided by our management, Jefferies analyzed the trading multiples of our company and the corresponding trading multiples of the DDi Selected Comparable Companies. In its analysis, Jefferies derived and compared multiples for our company and the DDi Selected Comparable Companies, calculated as follows:

Using the reference ranges for the benchmarks set forth below and our LTM Adjusted EBITDA as of April 2, 2012, 2012E Adjusted EBITDA and 2013E Adjusted EBITDA, Jefferies determined implied enterprise

values for our company, then subtracted indebtedness and added cash and cash equivalents to determine an implied equity value. After accounting for the vesting of in-the-money stock options (using the treasury stock method), this analysis indicated the ranges of implied values per share of our common stock, on a fully diluted basis, set forth opposite the relevant benchmarks below, compared, in each case, to the consideration of $13.00 per share of our common stock:

No company utilized in the comparable company analysis is identical to us. In evaluating the selected companies, Jefferies made judgments and assumptions with regard to industry performance, general business, economic, market and financial conditions and other matters, many of which are beyond our and Jefferies’ control. Mathematical analysis, such as determining the mean or median, is not in itself a meaningful method of using comparable company data.

Using publicly available information and other information, Jefferies examined the following eight transactions involving companies providing services and products to the printed circuit board market with enterprise values between $16.1 million and $948 million and announced since August 2006. The transactions considered and the month and year each transaction was announced were as follows:

Using publicly available estimates and other information for each of these transactions, Jefferies reviewed the enterprise value as a multiple of the target company’s LTM Adjusted EBITDA as of the announcement date of such transaction, which we refer to below as “Enterprise Value/LTM Adjusted EBITDA.”

Using a reference range of multiples of 5.5x to 6.5x our LTM Adjusted EBITDA as of April 2, 2012, Jefferies determined an implied enterprise value for our company, then subtracted indebtedness and added cash and cash equivalents to determine an implied equity value. After accounting for the vesting of in-the-money stock options (using the treasury stock method), this analysis indicated a range of implied values per share of our common stock of approximately $9.77 to $11.30, compared to the consideration of $13.00 per share of our common stock.

No transaction utilized as a comparison in the comparable transaction analysis is identical to the merger. In evaluating the merger, Jefferies made numerous judgments and assumptions with regard to industry performance, general business, economic, market, and financial conditions and other matters, many of which are beyond our and Jefferies’ control. Mathematical analysis, such as determining the mean or the median, is not in itself a meaningful method of using comparable transaction data.

Jefferies performed a discounted cash flow analysis to estimate the present value of the free cash flows of our company through the fiscal year ending December 31, 2016 using our management’s financial projections through 2016, discount rates ranging from 12.0% to 13.0%, and perpetual growth rates of free cash flow after fiscal year 2016 ranging from 2.0% to 3.0%. To determine the implied total equity value for our company, Jefferies subtracted indebtedness from and added cash and cash equivalents to our implied enterprise value. After accounting for the vesting of in-the-money stock options, this analysis indicated a range of implied values per share of our common stock of approximately $10.36 to $11.97, compared to the consideration of $13.00 per share of our common stock.

Jefferies also performed a discounted cash flow analysis to estimate the present value of the free cash flows of our company through the fiscal year ending December 31, 2016 using our management’s financial projections, discount rates ranging from 12.0% to 13.0%, and Adjusted EBITDA exit multiples ranging from 5.0x to 6.0x. To determine the implied total equity value for our company, Jefferies subtracted indebtedness from and added cash and cash equivalents to our implied enterprise value. After accounting for the vesting of in-the-money stock options, this analysis indicated a range of implied values per share of our common stock of approximately $11.63 to $13.38, compared to the consideration of $13.00 per share of our common stock.

Using publicly available information, Jefferies analyzed the premiums offered in all merger and acquisition transactions in the U.S. or Canada with a public company target announced over the past three years with a transaction value between $50 million and $500 million.

For each of these transactions, Jefferies calculated the premium represented by the offer price over the target company’s closing share price one day, one week and four weeks prior to the transaction’s announcement. This analysis indicated the following premiums for those time periods prior to announcement:

Using a reference range of the 25^th percentile, median and 75^th percentile premiums for each time period listed above, Jefferies performed a premiums paid analysis using the closing prices per share of our common stock for the periods 1-day, 1-week and 4-weeks prior to April 2, 2012. This analysis indicated a range of implied value per share of our common stock of approximately $11.69 to $18.44, compared to the consideration of $13.00 per share of our common stock.

Jefferies’ opinion was one of many factors taken into consideration by our board of directors in making its determination to approve the merger and should not be considered determinative of the views of our board of directors or management with respect to the merger or the consideration.

Jefferies was selected by our board of directors based on Jefferies’ qualifications, expertise and reputation. Jefferies is an internationally recognized investment banking and advisory firm. Jefferies, as part of its investment banking business, is regularly engaged in the valuation of businesses and securities in connection with mergers and acquisitions, negotiated underwritings, competitive biddings, secondary distributions of listed and unlisted securities, private placements, financial restructurings and other financial services.

Pursuant to an engagement agreement between us and Jefferies, dated August 9, 2010, we have agreed to pay Jefferies a fee in an amount not to exceed $3.9 million for its services, $500,000 of which was payable upon delivery of its opinion and the remainder of which is payable contingent upon the closing of the merger. We have agreed to reimburse Jefferies for expenses incurred. We also have agreed to indemnify Jefferies against liabilities arising out of or in connection with the services rendered and to be rendered by it under its engagement. Jefferies maintains a market in our securities, and in the ordinary course of business, Jefferies and its affiliates may trade or hold securities of our company or Viasystems and/or our or Viasystems’ affiliates for its own account and for the accounts of its customers and, accordingly, may at any time hold long or short positions in those securities. In addition, Jefferies may seek to, in the future, provide financial advisory and financing services to us, Viasystems or entities that are affiliated with us or Viasystems, for which it would expect to receive compensation. Except as otherwise expressly provided in its engagement letter with us, Jefferies’ opinion may not be used or referred to by us, or quoted or disclosed to any person in any matter, without Jefferies’ prior written consent.

We do not make public forecasts as to future performance or earnings due to the inherent unpredictability of the underlying assumptions and estimates. For internal planning purposes, but not for public disclosure, our management team periodically prepares a long-term financial plan, which our management team presents to our board. Our current internal financial plan, which we refer to as the company projections, was reviewed by our board of directors, used by Jefferies in connection with its financial analysis of the merger consideration (see “Opinion of DDi’s Financial Advisor” beginning on page 29) and provided to Viasystems. The company projections consisted of financial forecasts for the fiscal years ending December 31, 2012, 2013, 2014, 2015 and 2016. The company projections did not give effect to the merger. The company projections were based on numerous assumptions made by our management, including general increases in the market demand environment for our products and services, with stable to improving pricing and reasonably stable input pricing for materials and labor. These projections did not reflect a market slowdown over the forecast period. The PCB industry is frequently marked by business cycles with periods of increasing demand, accompanied with periods of slower demand or even significant demand declines. Further, we did not specifically forecast a reduction in the military/aerospace market despite the possibility of a general reduction in U.S. national defense spending as we intend to gain market share and grow our business in this market despite the macro environment pressures. We also did not forecast overall lower general market demand cycles due to the difficulty of predicting the timing and magnitude of such reductions in the demand for our products. As a result, over the planning period through 2016, the projections may be at risk for lower market demand.

The financial forecasts for 2012 through 2016 fiscal years included in the company projections were as follows:

Adjusted EBITDA in the forecasts excludes all stock-based compensation expense, amortization and restructuring charges. Free cash flow was calculated by adding back to net income depreciation and amortization, adding or subtracting changes in working capital and subtracting capital expenditures and other income. Adjusted EBITDA and free cash flow are non-GAAP measures that are used by our management as supplemental financial measurements to evaluate our operational trends and should not be considered as alternatives to net income or cash flow as indicators of our operating performance. Adjusted EBITDA and free cash flow are not defined under generally accepted accounting principles in the United States, which we refer to as GAAP. Accordingly, they have limitations in that they do not reflect all of the amounts associated with our company’s results of operations, as determined in accordance with GAAP, and may not be comparable measurements to those used by other companies.

The company projections above are included in this proxy statement to provide our stockholders access to certain nonpublic information considered by our board of directors in connection with its evaluation of the merger, provided to Viasystems for the purpose of allowing it to evaluate the merger and provided to Jefferies in connection with its opinion to our board of directors, as more fully described in the section entitled “Opinion of DDi’s Financial Advisor” beginning on page 29.

The financial forecasts stated above were prepared for internal use in connection with the merger and not with a view toward public disclosure or toward complying with GAAP, the published guidelines of the Securities and Exchange Commission regarding forecasts or the guidelines established by the American Institute of Certified Public Accountants for preparation and presentation of prospective financial information. The company projections included in this proxy statement were prepared by, and are the responsibility of, our management. We do not assume any responsibility to update these forecasts. Neither our independent registered public accounting firm, nor any other independent accountants, have compiled, examined or performed any procedures with respect to the financial forecasts contained herein, nor have they expressed any opinion or any other form of assurance on such forecasts or their achievability, and assume no responsibility for, and disclaim any association with, the financial forecasts. Furthermore, the financial forecasts do not take into account any circumstances or events occurring after the date the forecasts were prepared that were unforeseen by our management at the time of preparation. We have made publicly available our actual results of operations for the year ended December 31, 2011. Our stockholders should review our Annual Report on Form 10-K for the year ended December 31, 2011 to obtain this information. See “Where You Can Find More Information” beginning on page 82.

The inclusion of this information should not be regarded as an indication to any stockholder that our board of directors or any other recipient of this information considered, or now considers, it to be predictive of actual future results, and they should not be relied on as such. The company projections reflect numerous estimates and assumptions with respect to industry performance, general business, economic, regulatory, market and financial conditions, as well as matters specific to our business, all of which are difficult to predict and many of which are beyond our control. As a result, there can be no assurance that the forecasted results will be realized or that actual results will not be significantly higher or lower than such forecasts. As the forecasts cover multiple years, such

information by its nature becomes less predictive with each successive year. Also, the economic and business environments can and do change quickly, which adds a significant level of unpredictability, unreliability and execution risk. These factors create significant doubt as to whether the forecasts for fiscal years ended December 31, 2012 and beyond are likely to be achieved. As a result, the forecasts are not necessarily indicative of future results. In addition, our management prepared the forecasts prior to the execution of the merger agreement and, accordingly, the forecasts do not reflect the effects of the merger, which may cause results to differ materially. Accordingly, readers of this proxy statement are cautioned not to place undue reliance on the financial forecasts.

None of our company or our affiliates, advisors, officers, directors or representatives has made or makes any representation to any stockholder or other person regarding the ultimate performance of our company compared to the information contained in the forecasts or that forecasted results will be achieved.

BY INCLUDING IN THIS PROXY STATEMENT A SUMMARY OF OUR INTERNAL FINANCIAL FORECASTS, WE UNDERTAKE NO OBLIGATIONS TO UPDATE, OR PUBLICLY DISCLOSE ANY UPDATE TO, THESE FINANCIAL FORECASTS TO REFLECT CIRCUMSTANCES OR EVENTS, INCLUDING UNANTICIPATED EVENTS, THAT MAY HAVE OCCURRED OR THAT MAY OCCUR AFTER THE PREPARATION OF THESE FORECASTS, EVEN IN THE EVENT THAT ANY OR ALL OF THE ASSUMPTIONS UNDERLYING THE FINANCIAL FORECASTS ARE SHOWN TO BE IN ERROR OR CHANGE.

When considering the recommendation of our board of directors, you should be aware that members of our board of directors and our executive officers have interests in the merger in addition to their interests as DDi stockholders generally, pursuant to certain agreements between such directors and executive officers and DDi and, in the case of Mr. Williams, pursuant to a noncompetition agreement with Viasystems. These interests are described below and may be different from, or in conflict with, your interests as a DDi stockholder. The members of our board of directors were aware of the material facts as to these additional interests, and considered them, when they approved the merger agreement.

Our directors and executive officers are entitled to certain equity acceleration benefits in connection with the merger, as described below.

The employment arrangements of Messrs. Slomsky, Mathews, Barnes, and other members of DDi management with DDi will remain in effect following the merger in accordance with their terms. Their employment arrangements and unvested equity awards provide certain severance and equity acceleration benefits.

Mr. Williams will receive severance payments in accordance with the terms of his existing employment agreement with DDi, and pursuant to a letter agreement executed April 3, 2012 (described further below), these payments will be deposited into a grantor trust for distribution to Mr. Williams following a six-month delay that is required by law to avoid additional taxes. In addition, Mr. Williams has entered into a non-competition and non-solicitation agreement with Viasystems that will become effective upon the closing of the merger.

Certain executive officers of DDi may be entitled to accelerated payment of incentive bonus payments in connection with the merger.

Pursuant to the terms of the merger agreement, our stock incentive plans and the agreements evidencing equity awards, all then-unvested stock options will become fully vested at the effective time of the merger. The general treatment of options in the merger, including such awards held by our non-employee directors, is described below under “—Merger Consideration and Treatment of Stock Options” beginning on page 52.

The table below sets forth, as of March 30, 2012, for each of our directors and executive officers, the total number of all vested and unvested, in-the-money stock options held and the dollar value of such stock options calculated by subtracting the per share exercise price of the options from $13.00 per share and multiplying the amount of this difference by the number of shares subject to the options. All unvested options held by our executive officers and directors will accelerate at the closing of the merger. Our non-employee directors will become fully vested in their options on May 17, 2012 and therefore will receive no benefit from the acceleration if the closing of the merger occurs after this date.

Pursuant to the terms of his employment agreement with DDi, dated April 7, 2008, if the employment of Mr. Williams is terminated without “cause” (as defined in his employment agreement with DDi) at any time or due to his resignation for “good reason” (as defined in his employment agreement with DDi) within 12 months after a change in control of DDi, Mr. Williams is entitled to receive severance payments consisting of 24 months of base salary, payment of a pro rata portion of the then-current target incentive bonuses for the year in which the termination occurs (assuming 100% achievement of target objectives), plus a bonus payment equal to 200% of the target incentive bonuses (i.e., a 100% payout of target bonuses for the 24-month severance period). In such event, Mr. Williams’ basic employee benefits such as health insurance would be continued for the duration of the 24-month severance period. Such severance benefits are contingent on Mr. Williams executing a release of claims in favor of DDi. Further, any outstanding unvested equity awards held by Mr. Williams would

immediately vest upon termination of employment. Under Mr. Williams’ employment agreement, good reason includes, among other situations, Mr. Williams not holding the position of President and Chief Executive Officer of the successor company, reporting only to the Board of Directors of the successor to DDi following a change in control or DDi’s common stock not being listed on a U.S. national securities exchange following a change in control. The merger would constitute a change in control for purposes of these arrangements.

The employment agreement with Mr. Williams provides that DDi will indemnify Mr. Williams, on a fully grossed-up basis, for any tax imposed by Section 4999 of the Code on “excess parachute payments” (as defined in Section 280G of the Code) in connection with certain changes in control or by Section 409A of the Code. The agreement also provides that if any payment due to Mr. Williams is subject to a six-month delay pursuant to Section 409A of the Code, DDi will pay Mr. Williams interest on such delayed payments.

On April 3, 2012, DDi entered into a letter agreement with Mr. Williams, DDi’s Chief Executive Officer, which we refer to as the letter agreement. The letter agreement provides that if the merger becomes effective, DDi will, immediately prior to the effective time of the merger, irrevocably contribute to a grantor trust, which we refer to as the trust, the cash severance described in subsections (i), (ii) and (iii) of Section 5(e) of Mr. Williams’ employment agreement with DDi dated April 7, 2008, including interest thereon, that is payable in a lump sum six months after his separation from service if DDi (or the surviving corporation) terminates Mr. Williams’ employment without “cause” (as defined in Mr. Williams’ employment agreement with DDi), or Mr. Williams terminates his employment for “good reason” (as defined in Mr. Williams’ employment agreement with DDi).

Pursuant to each of their employment agreements with DDi, if the employment of Messrs. Mathews or Barnes is terminated without “cause” (as defined in their employment arrangements with DDi) at any time or due to the officer’s resignation for “good reason” (as defined in their employment arrangements with DDi) within 12 months after a change in control of DDi, the applicable individual is entitled to receive severance payments equal to twelve months of his base salary plus a bonus payment equal to a 100% payout of the target bonus for the year in which the termination occurred. In such event, Messrs. Mathews and Barnes are also entitled to reimbursement of their premiums for medical insurance under COBRA for twelve months after the date of termination. Such severance benefits are contingent on the executive executing a release of claims in favor of DDi. Under the employment agreements, good reason includes, among other situations, the successor to DDi following a change in control failing to offer the executive a position having duties, responsibilities, compensation and benefits substantially similar to those enjoyed by the executive officer immediately preceding the change in control or there is a change in the reporting structure so that executive officer reports to someone other than the CEO of DDi. The merger would constitute a change in control for purposes of these arrangements.

Pursuant to his offer letter with DDi, if the employment of Mr. Slomsky is terminated or the successor to DDi following a change of control fails to offer Mr. Slomsky a position having responsibilities, compensation and benefits substantially similar to those enjoyed by him immediately preceding the change of control, Mr. Slomsky is entitled to receive severance equal to six months of his base salary. Such severance benefits are contingent on Mr. Slomsky executing a release of claims in favor of DDi. The merger would constitute a change in control for purposes of these arrangements.

The DDi employment arrangements with Messrs. Mathews, Slomsky and Barnes will remain in effect following the merger in accordance with their terms.

On April 3 2012, Viasystems entered into a noncompetition agreement with Mikel H. Williams, DDi’s Chief Executive Officer (the “Noncompetition Agreement”). The Noncompetition Agreement provides that, effective upon the consummation of the Merger (i) Viasystems shall pay Mr. Williams $1.3 million and (ii) for a period of twenty-four months Mr. Williams shall not perform any executive management, technical, design or

supervisory services in the United States for certain of DDi’s key competitors. During the twenty-four month period, such agreement also prohibits Mr. Williams from soliciting any customers, employees or consultants of DDi or the Viasystems business unit into which DDi will be integrated.

Each of DDi’s executive officers is a participant in the DDi Corp. 2012 Senior Management Bonus Program (the “2012 DDi Bonus Program”). Each participant in the 2012 DDi Bonus Program has been assigned a target annual cash bonus. Participants may earn their bonuses based on (a) the achievement by DDi relative to its Net Adjusted EBITDA target for 2012; and (b) each participating employee meeting pre-established personal objectives. Selected employees, including all of the Company’s executive officers, are eligible to participate in the 2012 DDi Bonus Program. The 2012 DDi Bonus Program, as amended pursuant to the terms of the merger agreement, provides that, upon a change in control: (i) the bonus measurement period for purposes of calculating performance will terminate as of the effective time of the merger, (ii) the amount of any bonus under the 2012 DDi Bonus Program will be calculated based upon performance results through the effective time, and (iii) the amount of any bonus actually paid will be equal to the pro rata portion of the bonus so calculated attributable to the period from January 1, 2012 to the effective time (but guaranteed in no event to be less than 50% of the annual target bonus).

The following table sets forth the following cash compensation for each of our executive officers:

The following table is intended to comply with Item 402(t) of Regulation S-K and sets forth the amount of payments and benefits that may be paid or become payable to each named executive officer of DDi in connection with the merger pursuant to the DDi employment arrangements described above, assuming (i) the consummation of the merger occurred on June 30, 2012 and (ii) for purposes of estimating severance and equity acceleration benefits, that the service of the named executive officer also terminated on such date under the circumstances described below. The amounts shown in the table below do not include payments and benefits to the extent they are provided on a non-discriminatory basis to salaried employees generally upon termination of employment.

These include accrued salary and vacation pay and distributions of plan balances under the DDi Corp. 401(k) plan.

Viasystems has agreed to cause the surviving corporation, to the fullest extent permitted by applicable law, to honor all of our obligations to indemnify and hold harmless each person who is now, or has been at any time prior to the date of the merger agreement or who becomes prior to the effective time of the merger an officer or director of us or any of our subsidiaries as provided in our certificate of incorporation or bylaws, or the applicable charter documents of our subsidiary, in each case, as in effect on the date of the merger agreement, or pursuant to any other agreements in effect on the date of the merger agreement, including provisions relating to the advancement of expenses incurred in the defense of any action or as permitted under applicable law.

Viasystems has agreed to obtain or cause the surviving corporation to obtain prior to the effective time of the merger a “tail” officers’ and directors’ liability insurance policy, which by its terms shall survive the merger and shall provide such directors and officers with coverage for not less than six years following the effective time of the merger on terms and conditions no less favorable than the terms of our current directors’ and officers’ liability insurance policy in respect of actions or omissions of such officers and directors prior to the effective time of the merger in their capacities as such. In no event will Viasystems or the surviving corporation be required to pay more than 200% of the current annual premium paid by us for such policy to purchase the “tail” policy, but if such maximum payment amount is not sufficient to purchase the required coverage, then Viasystems will purchase such lesser coverage as may be obtained with such maximum payment amount.

If you do not vote for the adoption of the merger agreement at the special meeting and otherwise comply with the applicable statutory procedures of Section 262 of the DGCL, summarized herein, you may be entitled to appraisal rights under Section 262 of the DGCL. In order to exercise and perfect appraisal rights, a record holder

of our common stock must follow the steps prescribed in Section 262 of the DGCL and summarized below properly and in a timely manner.

Section 262 of the DGCL is reprinted in its entirety as Annex E to this proxy statement. Set forth below is a summary description of Section 262 of the DGCL. The following summary describes the material aspects of Section 262 of the DGCL, and the law relating to appraisal rights and is qualified in its entirety by reference to Annex E. All references in Section 262 and this summary to “stockholder” are to the record holder of the shares of our common stock immediately prior to the effective time of the merger as to which appraisal rights are asserted. Failure to comply strictly with the procedures set forth in Section 262 of the DGCL will result in the loss of appraisal rights.

ANY DDI STOCKHOLDER WHO WISHES TO EXERCISE APPRAISAL RIGHTS OR WHO WISHES TO PRESERVE HIS, HER OR ITS RIGHT TO DO SO SHOULD REVIEW ANNEX E CAREFULLY AND SHOULD CONSULT HIS, HER OR ITS LEGAL ADVISOR, SINCE FAILURE TO TIMELY COMPLY WITH THE PROCEDURES SET FORTH THEREIN WILL RESULT IN THE LOSS OF SUCH RIGHTS.

Under the DGCL, holders of our common stock who follow the procedures set forth in Section 262 of the DGCL will be entitled to have their shares appraised by the Delaware Court of Chancery, or the Delaware Court, and to receive payment in cash of the “fair value” of those shares, exclusive of any element of value arising from the accomplishment or expectation of the merger, together with interest, if any, on the amount determined to be the fair value.

Under Section 262 of the DGCL, where a merger agreement relating to a proposed merger is to be submitted for adoption at a meeting of stockholders, as in the case of the special meeting, the corporation, not less than 20 days prior to such meeting, must notify each of its stockholders who was a stockholder on the record date with respect to shares for which appraisal rights are available, that appraisal rights are so available, and must include in each such notice a copy of Section 262 of the DGCL. This proxy statement constitutes such notice to the holders of our common stock and Section 262 of the DGCL is attached to this proxy statement as Annex E. Any stockholder who wishes to exercise such appraisal rights or who wishes to preserve his right to do so should review the following discussion and Annex E carefully and should consult his, her or its legal advisor, because failure to timely and properly comply with the procedures specified will result in the loss of appraisal rights under the DGCL.

If you wish to exercise appraisal rights you must not vote for the adoption of the merger agreement and must deliver to DDi, before the vote on the proposal to adopt the merger agreement, a written demand for appraisal of such stockholder’s shares of our common stock. If you sign and return a proxy card or vote by submitting a proxy by telephone, through the Internet or by fax, without expressly directing that your shares of our common stock be voted against the adoption of the merger agreement, you will effectively waive your appraisal rights because such shares represented by the proxy will be voted for the adoption of the merger agreement. Accordingly, if you desire to exercise and perfect appraisal rights with respect to any of your shares of common stock, you must either refrain from executing and returning the enclosed proxy card and from voting in person or by submitting a proxy by telephone, through the Internet or by fax, in favor of the proposal to adopt the merger agreement or check either the “against” or the “abstain” box next to the proposal on such card or vote in person or by submitting a proxy by telephone, through the Internet or by fax, against the proposal or register in person an abstention with respect thereto. A vote or proxy against the adoption of the merger agreement will not, in and of itself, constitute a demand for appraisal.

A demand for appraisal will be sufficient if it reasonably informs DDi of the identity of the stockholder and that such stockholder intends thereby to demand appraisal of such stockholder’s shares of common stock. This written demand for appraisal must be separate from any proxy or vote abstaining from or voting against the adoption of the merger agreement. If you wish to exercise your appraisal rights you must be the record holder of

such shares of our common stock on the date the written demand for appraisal is made and you must continue to hold such shares through the effective time of the merger. Accordingly, a stockholder who is the record holder of shares of common stock on the date the written demand for appraisal is made, but who thereafter transfers such shares prior to the effective time of the merger, will lose any right to appraisal in respect of such shares.

Only a holder of record of shares of our common stock on [ ], the record date for the special meeting, is entitled to assert appraisal rights for such shares of our common stock registered in that holder’s name. A demand for appraisal should be executed by or on behalf of the holder of record, fully and correctly, as the holder’s name appears on the stock certificates and must state that such person intends thereby to demand appraisal of his, her or its shares. If the shares are owned of record in a fiduciary capacity, such as by a trustee, guardian or custodian, execution of the demand for appraisal should be made in that capacity, and if the shares are owned of record by more than one person, as in a joint tenancy or tenancy in common, the demand should be executed by or on behalf of all joint owners. An authorized agent, including one for two or more joint owners, may execute the demand for appraisal on behalf of a holder of record; however, the agent must identify the record owner or owners and expressly disclose the fact that, in executing the demand, he or she is acting as agent for such owner or owners.

A record holder such as a broker who holds shares as nominee for several beneficial owners may exercise appraisal rights with respect to the shares of our common stock held for one or more beneficial owners while not exercising such rights with respect to the shares held for other beneficial owners; in such case, the written demand should set forth the number of shares as to which appraisal is sought. Where the number of shares of our common stock is not expressly stated, the demand will be presumed to cover all shares held in the name of the record owner. If you hold your shares in brokerage accounts or other nominee forms and wish to exercise your appraisal rights, you are urged to consult with your broker to determine the appropriate procedures for the making of a demand for appraisal.

All written demands for appraisal of shares must be mailed or delivered to: DDi Corp., 1220 N. Simon Circle, Anaheim, California 92806, Attention: Corporate Secretary.

Within ten days after the effective time of the merger, we will notify each stockholder of the effective time of the merger who properly asserted appraisal rights under Section 262 and has not voted for the adoption of the merger agreement. Within 120 days after the effective time of the merger, but not thereafter, we or any stockholder who has complied with the statutory requirements summarized above may commence an appraisal proceeding by filing a petition in the Delaware Court demanding a determination of the fair value of the shares held by such stockholder. If no such petition is filed, appraisal rights will be lost for all stockholders who had previously demanded appraisal of their shares. We are not under any obligation, and we have no present intention, to file a petition with respect to appraisal of the value of the shares. Accordingly, if you wish to exercise your appraisal rights, you should regard it as your obligation to take all steps necessary to perfect your appraisal rights in the manner prescribed in Section 262 of the DGCL.

Within 120 days after the effective time of the merger, any stockholder who has complied with the provisions of Section 262 of the DGCL will be entitled, upon written request, to receive from us a statement setting forth the aggregate number of shares of our common stock not voted in favor of adoption of the merger agreement and with respect to which demands for appraisal were received by us, and the number of holders of such shares. Such statement must be mailed within ten days after the written request therefor has been received by us or within ten days after expiration of the period for delivery of appraisal demands, whichever is later. A person who is the beneficial owner of shares of such stock held either in a voting trust or by a nominee on behalf of such person may, in such person’s own name, file an appraisal petition or request from us the statement described in this paragraph.

If a petition for an appraisal is timely filed and a copy thereof served upon us, we will then be obligated, within 20 days after such service, to file with the Delaware Register in Chancery a duly verified list containing

the names and addresses of the stockholders who have demanded appraisal of their shares and with whom agreements as to the value of their shares have not been reached. After notice to the stockholders as required by the Delaware Court, the Delaware Court is empowered to conduct a hearing on such petition to determine those stockholders who have complied with Section 262 and who have become entitled to appraisal rights thereunder. The Delaware Court may require the stockholders who demanded appraisal rights of our shares of common stock to submit their stock certificates to the Register in Chancery for notation thereon of the pendency of the appraisal proceeding; and if any stockholder fails to comply with such direction, the Delaware Court may dismiss the proceedings as to such stockholder.

After the Delaware Court determines which stockholders are entitled to appraisal, the appraisal proceeding shall be conducted in accordance with the rules of the Delaware Court, including any rules specifically governing appraisal proceedings. Through such proceeding the Delaware Court shall determine the fair value of the shares exclusive of any element of value arising from the accomplishment or expectation of the merger, together with interest, if any, to be paid upon the amount determined to be the fair value. In determining such fair value, the Delaware Court shall take into account all relevant factors. Unless the Delaware Court in its discretion determines otherwise for good cause shown, interest from the effective date of the merger through the date of payment of the judgment shall be compounded quarterly and shall accrue at 5% over the Federal Reserve discount rate (including any surcharge) as established from time to time during the period between the effective date of the merger and the date of payment of the judgment. If you are considering seeking appraisal, you should be aware that the fair value of your shares as determined under Section 262 of the DGCL could be more than, the same as or less than the consideration you are entitled to receive pursuant to the merger agreement if you did not seek appraisal of your shares and that investment banking opinions as to the fairness from a financial point of view of the consideration payable in a merger are not necessarily opinions as to fair value under Section 262 of the DGCL.

The Delaware Court will direct the payment of the fair value of the shares of our common stock to those stockholders who have perfected appraisal rights, together with interest, if any. The Delaware Court will determine the amount of interest, if any, to be paid on the amounts to be received by persons whose shares of our common stock have been appraised. The costs of the action (which do not include attorneys’ or expert fees or expenses) may be determined by the Delaware Court and taxed upon the parties as the Delaware Court deems equitable. The Delaware Court may also order that all or a portion of the expenses incurred by any stockholder in connection with an appraisal, including without limitation reasonable attorneys’ fees and the fees and expenses of experts utilized in the appraisal proceeding, be charged pro rata against the value of all of the shares entitled to appraisal. In the absence of such determination or assessment, each party bears its own expenses.

Any stockholder who has duly demanded and perfected an appraisal in compliance with Section 262 of the DGCL will not, after the effective time of the merger, be entitled to vote his or her shares for any purpose or be entitled to the payment of dividends or other distributions thereon, except dividends or other distributions payable to holders of record of shares of our common stock as of a date prior to the effective time of the merger.

At any time within 60 days after the effective time of the merger, any stockholder who has not commenced an appraisal proceeding or joined that proceeding as a named party will have the right to withdraw his or her demand for appraisal and to accept the cash payment for his or her shares pursuant to the merger agreement. After this period, a stockholder may withdraw his or her demand for appraisal only with our written consent. If no petition for appraisal is filed with the Delaware Court within 120 days after the effective time of the merger, a stockholder’s right to appraisal will cease and he or she will be entitled to receive the cash payment for his or her shares pursuant to the merger agreement, as if he or she had not demanded appraisal of his or her shares. No petition timely filed in the Delaware Court demanding appraisal will be dismissed as to any stockholder without the approval of the Delaware Court, and such approval may be conditioned on such terms as the Delaware Court deems just; provided, however, that any stockholder who has not commenced an appraisal proceeding or joined that proceeding as a named party may withdraw his, her or its demand for appraisal and accept the merger consideration offered pursuant to the merger agreement within 60 days after the effective date of the merger.

You will fail to perfect, or effectively lose or withdraw, your right to appraisal if, among other things, no petition for appraisal is filed within 120 days after the effective time of the merger, or if you deliver to us a written withdrawal of your demand for appraisal. Any such attempt to withdraw an appraisal demand more than 60 days after the effective time of the merger will require our written approval.

If you desire to exercise your appraisal rights, you must not vote for the adoption of the merger agreement and must strictly comply with the procedures set forth in Section 262 of the DGCL.

Failure to take any required step in connection with the exercise of appraisal rights will result in the termination or waiver of such rights.

THE PROCESS OF DEMANDING AND EXERCISING APPRAISAL RIGHTS REQUIRES STRICT COMPLIANCE WITH TECHNICAL PREREQUISITES. THOSE INDIVIDUALS OR ENTITIES WISHING TO EXERCISE THEIR APPRAISAL RIGHTS SHOULD CONSULT WITH THEIR OWN LEGAL COUNSEL IN CONNECTION WITH COMPLIANCE UNDER SECTION 262 OF THE DGCL. TO THE EXTENT THERE ARE ANY INCONSISTENCIES BETWEEN THE FOREGOING SUMMARY AND SECTION 262 OF THE DGCL, THE DGCL SHALL GOVERN.

Although we are authorized to issue RSUs and restricted stock, we currently do not have any RSUs or restricted stock outstanding.

The merger will become effective upon the filing of a certificate of merger with the Secretary of State of the State of Delaware or at such later time as is agreed upon by Viasystems and us and specified in such certificate of merger. The closing of the merger will occur as soon as practicable (but in no event later than the third business day) after the satisfaction or waiver of the conditions to the closing of the merger set forth in the merger agreement and described in this proxy statement (other than conditions which by their terms are required to be satisfied or waived at the closing, but subject to the satisfaction or waiver of such conditions), or on such later date as specified by Viasystems in order to accommodate Viasystems’ contemplated financing of the transaction (but in no event later than August 15, 2012, or September 15, 2012 under certain conditions in which matters related to antitrust laws prevent the closing at August 15, 2012), unless Viasystems and we agree to hold the closing at a different time. We currently anticipate the merger to be completed in the second quarter of calendar year 2012.

If the merger is completed, our common stock will be delisted from and will no longer be traded on the NASDAQ Global Select Market and will be deregistered under the Securities Exchange Act. Following the closing of the merger, we will no longer be an independent public company.

The following discussion summarizes the material U.S. federal income tax consequences of the merger to holders of DDi common stock. This discussion is based upon the provisions of the Internal Revenue Code of 1986, as amended, which we refer to as the Code, the U.S. Treasury Regulations promulgated thereunder and judicial and administrative rulings, all as in effect as of the date of this proxy statement and all of which are subject to change or varying interpretation, possibly with retroactive effect. Any such changes could affect the accuracy of the statements and conclusions set forth herein.

This discussion assumes that holders of DDi common stock hold their shares as capital assets within the meaning of Section 1221 of the Code (generally, property held for investment). This discussion does not address all aspects of U.S. federal income taxation that may be relevant to a holder of DDi common stock in light of such holder’s particular circumstances, nor does it discuss the special considerations applicable to holders of our common stock subject to special treatment under the U.S. federal income tax laws, such as, for example, financial institutions or broker-dealers, mutual funds, partnerships or other pass-through entities and their partners or members, tax-exempt organizations, insurance companies, dealers in securities or foreign currencies, traders in securities who elect the mark-to-market method of accounting, controlled foreign corporations, passive foreign investment companies, U.S. expatriates, holders who acquired their DDi common stock through the exercise of options or otherwise as compensation, holders who hold their DDi common stock as part of a hedge, straddle, constructive sale or conversion transaction, U.S. holders (as defined below) whose functional currency is not the U.S. dollar, and holders who exercise appraisal rights. This discussion does not address any aspect of foreign, state, local, alternative minimum, estate, gift or other tax law that may be applicable to a holder.

We intend this discussion to provide only a general summary of the material U.S. federal income tax consequences of the merger to holders of DDi common stock. We do not intend it to be a complete analysis or description of all potential U.S. federal income tax consequences of the merger. The U.S. federal income tax laws are complex and subject to varying interpretation. Accordingly, the Internal Revenue Service may not agree with the tax consequences described in this proxy statement.

If an entity or arrangement treated as a partnership for U.S. federal income tax purposes holds DDi common stock, the tax treatment of a partner in such partnership generally will depend on the status of the partner and activities of the partnership. If you are a partner of a partnership holding DDi common stock, you should consult your own tax advisor.

All holders should consult their own tax advisors to determine the particular tax consequences to them (including the application and effect of any state, local or foreign income and other tax laws) of the receipt of cash in exchange for shares of DDi common stock pursuant to the merger.

For purposes of this discussion, the term “U.S. holder” means a beneficial owner of DDi common stock that is, for U.S. federal income tax purposes:

A “non-U.S. holder” is a beneficial owner (other than a partnership) of DDi common stock that is not a U.S. holder.

The conversion of shares of DDi common stock into cash pursuant to the merger will be a taxable transaction for U.S. federal income tax purposes. A U.S. holder generally will recognize gain or loss for U.S. federal income tax purposes equal to the difference, if any, between the amount of cash received pursuant to the merger and such U.S. holder’s adjusted tax basis in the shares converted into cash pursuant to the merger. Such gain or loss generally will be capital gain or loss, and will be long-term capital gain or loss if the holder’s holding period for such shares exceeds one year as of the date of the merger. Long-term capital gains for certain non-corporate U.S. holders, including individuals, are generally eligible for a reduced rate of federal income taxation. The deductibility of capital losses is subject to limitations. If a U.S. holder acquired different blocks of DDi common stock at different times or different prices, such U.S. holder must determine its tax basis, holding period, and gain or loss separately with respect to each block of DDi common stock.

A U.S. holder may, under certain circumstances, be subject to information reporting and backup withholding at the applicable rate (currently, 28%) with respect to the cash received pursuant to the merger, unless such holder properly establishes an exemption or provides its correct tax identification number and otherwise complies with the applicable requirements of the backup withholding rules. Backup withholding is not an additional tax. Any amounts withheld under the backup withholding rules can be refunded or credited against a payee’s U.S. federal income tax liability, if any, provided that such U.S. holder furnishes the required information to the Internal Revenue Service in a timely manner.

Any gain recognized on the receipt of cash pursuant to the merger by a non-U.S. holder generally will not be subject to U.S. federal income tax unless:

A non-U.S. holder will be subject to information reporting and, in certain circumstances, backup withholding (currently, at a rate of 28%) will apply with respect to the cash received by such holder pursuant to the merger, unless such non-U.S. holder certifies under penalties of perjury that it is a non-U.S. holder (and the payor does not have actual knowledge or reason to know that the holder is a United States person as defined under the Code) or such holder otherwise establishes an exemption from backup withholding. Backup

withholding is not an additional tax and any amounts withheld under the backup withholding rules may be refunded or credited against a non-U.S. holder’s U.S. federal income tax liability, if any.

Under specified circumstances a holder may be entitled to appraisal rights in connection with the merger. If a holder of DDi common stock receives cash pursuant to the exercise of appraisal rights, such holder generally will recognize gain or loss, measured by the difference between the cash received and such holder’s tax basis in such stock. Interest, if any, awarded in an appraisal proceeding by a court would be included in such holder’s income as ordinary income for U.S. federal income tax purposes. Holders of DDi common stock who exercise appraisal rights are urged to consult their own tax advisors.

THE UNITED STATES FEDERAL INCOME TAX DISCUSSION SET FORTH ABOVE IS INCLUDED FOR GENERAL INFORMATION PURPOSES ONLY AND IS NOT A COMPLETE ANALYSIS OR DISCUSSION OF ALL POTENTIAL TAX CONSEQUENCES RELEVANT TO DDI STOCKHOLDERS. THE TAX CONSEQUENCES OF THE MERGER MAY VARY DEPENDING UPON THE PARTICULAR CIRCUMSTANCES OF EACH STOCKHOLDER. YOU SHOULD CONSULT YOUR TAX ADVISOR CONCERNING THE FEDERAL, STATE, LOCAL, FOREIGN OR OTHER TAX CONSEQUENCES OF THE MERGER TO YOU.

The closing of the merger is subject to expiration or termination of the applicable waiting periods under the HSR Act and the rules thereunder. Under the HSR Act and the rules thereunder, the merger may not be completed unless certain information has been furnished to the Antitrust Division of the U.S. Department of Justice and to the Federal Trade Commission and applicable waiting periods expire or are terminated. The HSR Act requires the parties to observe a 30-day waiting period (the “initial 30-day waiting period”), during which time the merger may not be consummated, unless that initial 30-day waiting period is terminated early. If, before the expiration of the initial 30-day waiting period, the Antitrust Division of the U.S. Department of Justice or the Federal Trade Commission issues a request for additional information, the parties may not consummate the transaction until 30 days after DDi and Viasystems have each substantially complied with such request for additional information (unless this period is shortened pursuant to a grant of earlier termination). DDi and Viasystems expects to file their respective notification and report forms pursuant to the HSR Act with the Antitrust Division of the U.S. Department of Justice and the Federal Trade Commission during the week of April 16, 2012.

At any time before the effective time of the merger, the Federal Trade Commission, the Antitrust Division of the U.S. Department of Justice, state attorneys general, or private parties can file suit under the antitrust laws to enjoin consummation of the merger or to impose conditions on the merger. There can be no assurance that the merger will not be challenged on antitrust grounds or, if such a challenge is made, that the challenge will not be successful.

On April 5, 2012, a purported class action lawsuit on behalf of our stockholders was filed in Superior Court, Orange County, State of California, captioned Irving S. Braun, et. al. v. DDi Corp., et. al., Case No. 30-2012-00559763-CU-BT-CXC. On April 5, 2012, another purported class action lawsuit was filed in Superior Court, Orange County, State of California, on behalf of our stockholders captioned Lousiana Municipal Police Employees’ Retirement System v. DDi Corp., et. al., Case No. 30-2012-00559772-CU-BT-CXC. On April 9,

2012, a purported class action lawsuit was filed in the Court of Chancery of the State of Delaware captioned Joseph P. Daly v. DDi Corp., et. al., Civil Action No. 7407-VCG.

These complaints name as the primary defendants, DDi, Viasystems, merger sub and the members of our board of directors and generally allege, among other things, that (i) that the members of our board of directors violated the fiduciary duties owed to stockholders by approving the merger agreement, (ii) that the members of our board of directors engaged in an unfair process and agreed to a price that allegedly fails to maximize value for stockholders and (iii) that DDi, Viasystems and merger sub aided and abetted the board members’ alleged breach of fiduciary duties. These complaints seek, among other things, to enjoin the transaction until corrective actions are taken, as well as to award to plaintiffs the costs and disbursements of the action, including attorneys’ fees and experts’ fees. We, the members of our board of directors and each of the other named defendants intend to defend ourselves vigorously in these actions.

The following summary describes certain material provisions of the merger agreement. This summary is not complete and is qualified in its entirety by reference to the complete text of the merger agreement, which is attached to this proxy statement as Annex A and incorporated into this proxy statement by reference. We urge you to read carefully the merger agreement in its entirety because this summary may not contain all the information about the merger agreement that is important to you.

The merger agreement and the following description have been included to provide you with information regarding the terms of the merger agreement. It is not intended to provide any other factual information about DDi or Viasystems. Such information can be found elsewhere in this proxy statement and in the other public filings we and Viasystems make with the SEC, which are available, without charge, at http://www.sec.gov.

The representations and warranties described below and included in the merger agreement were made for the purposes of the merger agreement by DDi and Viasystems to each other as of specific dates. The assertions embodied in those representations and warranties were made solely for purposes of the merger agreement and may be subject to important qualifications and limitations agreed to by DDi and Viasystems in connection with negotiating the terms of that agreement. Moreover, the representations and warranties may be subject to a contractual standard of materiality that may be different from what may be viewed as material to stockholders, or may have been made for the purpose of allocating risk between DDi and Viasystems rather than establishing the matters addressed by such representations and warranties as facts. The merger agreement is described in this proxy statement and included as Annex A only to provide you with information regarding its terms and conditions, and not to provide any other factual information regarding DDi and Viasystems or their respective businesses.

Subject to the terms and conditions of the merger agreement and in accordance with Delaware law, at the effective time of the merger, merger sub, a wholly-owned subsidiary of Viasystems and a party to the merger agreement, will merge with and into us. We will survive the merger as a wholly-owned subsidiary of Viasystems under the name of Viasystems North America, Inc. and the separate corporate existence of merger sub will cease.

The merger will become effective upon the filing of a certificate of merger with the Secretary of State of the State of Delaware or at such later time as is agreed upon by Viasystems and us and specified in such certificate of merger. The closing of the merger will occur as soon as practicable (but in no event later than the third business day) after the satisfaction or waiver of the conditions to the closing of the merger set forth in the merger agreement and described in this proxy statement (other than conditions which by their terms are required to be satisfied or waived at the closing, but subject to the satisfaction or waiver of such conditions), or on such later date as specified by Viasystems in order to accommodate Viasystems’ contemplated financing of the transaction (but in no event later than August 15, 2012, or September 15, 2012 under certain conditions in which matters related to antitrust laws prevent the closing at August 15, 2012), unless Viasystems and we agree to hold the closing at a different time. Although we expect to complete the merger as soon as possible following the special meeting of our stockholders (if our stockholders adopt the merger agreement), we cannot specify when or assure that we and Viasystems will satisfy or waive all of the conditions to the closing of the merger. See “—Conditions to the Closing of the Merger” beginning on page 68.

The merger agreement provides that each share of our common stock outstanding immediately prior to the effective time of the merger (other than shares held by us, Viasystems or by holders properly exercising appraisal rights under Delaware law) shall be converted and exchanged automatically at the effective time of the merger into the right to receive $13.00 in cash, without interest.

If any of our stockholders properly demand appraisal rights with respect to any of our shares of common stock, then we will treat those shares as described under “The Merger—Appraisal Rights” beginning on page 43.

Each option to acquire shares of our common stock that is outstanding and unexercised immediately prior to the effective time of the merger, and that is not then vested and exercisable, will become fully vested on an accelerated basis immediately prior to the effective time of the merger. As of the effective time of the merger, each option to acquire shares of our common stock that is outstanding and unexercised immediately prior thereto shall be canceled in exchange for the right to receive from Viasystems or the surviving corporation as soon as practicable after the effective time of the merger an amount in cash (without interest, and less all applicable deductions and withholding taxes) equal to the product of:

Prior to the effective time of the merger, Viasystems or merger sub will appoint a paying agent reasonably satisfactory to us to facilitate the receipt by our stockholders of the merger consideration in connection with the merger. Prior to the effective time, Viasystems will deposit or cause the surviving corporation to deposit with the paying agent cash in an amount sufficient to pay the aggregate merger consideration required to be paid in accordance with the merger agreement.

As promptly as reasonably practicable after the effective time of the merger, Viasystems and the surviving corporation will cause the paying agent to mail to each person who immediately prior to the effective time of the merger was a holder of record of shares of our common stock entitled to receive the merger consideration:

If any portion of the merger consideration is to be paid to a person other than the person in whose name the surrendered certificates or the transferred uncertificated shares are registered, such payment will be subject to the conditions that:

Until surrendered or transferred, as the case may be, each such certificate or uncertificated share shall be deemed at all times after the effective time to represent only the right to receive the merger consideration upon such surrender.

After the effective time of the merger, each holder of shares of our common stock entitled to receive the merger consideration will, upon surrender to the paying agent of a certificate or compliance with the reasonable procedures established by the paying agent for the delivery of uncertificated shares, together with a properly completed letter of transmittal, be entitled to receive the merger consideration of $13.00 in cash, for each such share of our common stock. No interest will be paid or will accrue on the cash payable to the holders of such shares.

If any certificate representing the shares to be converted into the merger consideration has been lost, stolen or destroyed, the paying agent will pay the merger consideration with respect to each such share formerly represented by a certificate upon the making of an affidavit of that fact by the person claiming such certificate to be lost, stolen or destroyed and, if required by the surviving corporation, the posting by such person of a bond in such reasonable amount as the surviving corporation may direct as indemnity against any claim that may be made against the surviving corporation with respect to such certificate.

At the effective time, our stock transfer books will be closed and there will be no further registration of transfers of such shares thereafter on our records. From and after the effective time, the holders of such shares shall cease to have any rights with respect to such shares, except as otherwise provided in the merger agreement, the certificate of incorporation of the surviving corporation or by applicable law.

At any time following the six-month anniversary of the closing date of the merger, the surviving corporation may require the paying agent to deliver to it any funds previously made available to the paying agent that have not been disbursed to holders of shares converted into the right to receive the merger consideration. After such remaining funds have been delivered to the surviving corporation, the holders of such shares will only be able to look to the surviving corporation for, and the surviving corporation will remain liable for, payment of their claim for the merger consideration. Viasystems has agreed to take all actions necessary to ensure that the surviving corporation has or has access to sufficient funds to make such payments. Any portion of the merger consideration remaining unclaimed by holders of such shares as of a date which is immediately prior to the time the amounts would otherwise escheat to or become the property of any governmental entity will, to the extent permitted by applicable law, become the property of the surviving corporation, free and clear of any claims or interest of any person previously entitled thereto. None of Viasystems, the surviving corporation or the paying agent will be liable to any holder of such shares for such shares (or dividends or distributions with respect to such shares) or any amount required to be delivered to a public official pursuant to any applicable abandoned property, escheat or similar law.

The merger agreement provides that merger sub’s directors and officers immediately prior to the effective time of the merger will be the directors and officers, respectively, of the surviving corporation until their respective successors are duly elected or appointed and qualified or until the earlier of their death, resignation or removal.

We have made a number of representations and warranties to Viasystems and merger sub in the merger agreement regarding aspects of our business and other matters pertinent to the merger. The topics covered by these representations and warranties include the following:

Some of our representations and warranties are qualified by a material adverse effect standard. The merger agreement provides that a material adverse effect, with respect to us, is any effect, event, occurrence, development, state of facts or change (whether or not foreseeable as of the date of the merger agreement) that, individually or in the aggregate with all other effects, events, occurrences, developments, state of facts or changes, (a) is, or would reasonably be expected to be, materially adverse to the business, assets, results of operations or financial condition of us and our subsidiaries, taken as a whole, or (b) would prevent or materially impair our ability to perform our obligations under the merger agreement or consummate the transactions contemplated by the merger agreement. However, with respect to clause (a) above, the determination of a material adverse effect shall exclude any effect, event, occurrence, development, state of facts or change arising out of or resulting from:

provided, however, any matters described in the second, third and fourth bullets above may be taken into account in the determination of a material adverse effect to the extent that we or such subsidiary is materially disproportionately adversely affected by such matters relative to other participants in the industries in which we or such subsidiary participates.

Viasystems and merger sub have made a number of representations and warranties to us regarding various matters pertinent to the merger. The topics covered by these representations and warranties include the following:

The representations and warranties of each of the parties to the merger agreement will expire upon effective time of the merger.

In the merger agreement, we have agreed that until the effective time of the merger or the termination of the merger agreement, subject to certain exceptions in the merger agreement and the matters contained in the disclosure schedule we delivered in connection with the merger agreement, we will, and we will cause each of our subsidiaries to, conduct our and their business in the ordinary course consistent with past practice and to use our and their commercially reasonable efforts to:

In addition, we have agreed, subject to specified exceptions in the merger agreement and the matters contained in the disclosure schedule we delivered in connection with the merger agreement, that until the effective time of the merger or the termination of the merger agreement without Viasystems’ written consent (which cannot be unreasonably withheld, conditioned or delayed) we will not, and will cause our subsidiaries not to:

Viasystems has provided us with a commitment letter with respect to a bridge loan which Viasystems has represented provides sufficient funds for Viasystems and merger sub to consummate the transactions contemplated by the merger agreement and has agreed to use its reasonable best efforts to obtain and effectuate the debt financing contemplated by its commitment letter on the terms set forth therein. However, Viasystems (or one of its affiliates) may instead, or in addition, complete a debt securities financing, bank loan financing or other debt financing whose net cash proceeds replace amounts that were to be provided under the bridge loan pursuant to the commitment letter and that were required for the transactions contemplated by the merger agreement. Viasystems and merger sub are not required to consummate the merger before the earlier of (i) the consummation of such debt financing and (ii) August 15, 2012 (or September 15, 2012 under certain conditions in which matters related to antitrust laws prevent the closing at August 15, 2012).

Other than in connection with such a debt offering, Viasystems shall not, nor shall it permit any of its subsidiaries or affiliates to, without our prior written consent, take any action or enter into any transaction, including, without limitation, any merger, acquisition, joint venture, disposition, lease, contract or debt or equity financing that would reasonably be expected to materially impair, delay or prevent the debt contemplated by Viasystems’ commitment letter. Other than in connection with such a debt offering, neither Viasystems nor merger sub shall amend or alter, or agree to amend or alter, the commitment letter in any manner that would materially impair, delay or prevent the closing without our prior written consent. If Viasystems’ commitment letter expires or terminates for any reason, except to the extent Viasystems has completed such a debt offering, Viasystems has agreed to use its reasonable best efforts to obtain, and will provide us with a copy of, a new financing commitment that provides for a sufficient amount of financing for Viasystems to consummate the transactions contemplated by the merger agreement on funding conditions not materially less favorable than those included in its commitment letter as originally issued and other terms and conditions the aggregate effect of which is not materially adverse to Viasystems in comparison with those contained in the commitment letter as originally issued, which extension or new commitment shall include a termination date not earlier than August 15, 2012. Viasystems has agreed to accept any such commitment letter if the funding conditions and other terms and conditions contained therein are not materially adverse to Viasystems in comparison with those contained in its commitment letter as originally issued.

The merger agreement provides that our board of directors will not, and will not agree or resolve to:

Notwithstanding the foregoing, subject to the conditions described below, our board of directors may, at any time prior to the effective time of the merger effect an adverse recommendation change in response to a written bona fide acquisition proposal, which our board of directors determines in good faith, after consultation with our financial advisors and outside counsel, and after giving effect to all of the adjustments to the terms of the merger agreement which may be offered by Viasystems, including those described in the third bullet below, to be a superior proposal. Our board of directors may only effect an adverse recommendation change if:

The covenant in the merger agreement generally prohibiting us from soliciting acquisition proposals does not prevent us from complying with Rule 14d-9, 14e-2(a) or Item 1012(a) of Regulation M-A promulgated under the Securities Exchange Act; provided, however, that any disclosure other than (i) a “stop, look and listen” or similar communication of the type contemplated by Rule 14d-9(f) under the Securities Exchange Act, (ii) an express rejection of any applicable acquisition proposal or (iii) an express reaffirmation of our board of directors recommendation of the merger and the merger agreement together with a factual description of events or actions leading up to such disclosure that have been taken by us and that are described above and permitted under the no-solicitation provisions of the merger agreement or actions taken or notices delivered to Viasystems by us that are described above and required by the no-solicitation provisions of the merger agreement, will, in each case, be deemed to be an adverse recommendation change.

An “acquisition proposal” means any inquiry, proposal, offer or indication of interest (whether or not in writing) for or relating to (in one transaction or a series of related transactions) any of the following:

A “superior proposal” means any bona fide acquisition proposal made by any person that:

We have agreed to give notice of, convene and hold a stockholders’ meeting, for the purpose of the adoption of the merger agreement by our stockholders, as promptly as practicable, and in any event (to the extent permissible under applicable law and orders) as soon as practicable following the mailing of the definitive proxy statement to our stockholders (but in no event later than 30 calendar days following the date of such mailing). We have agreed to consult with Viasystems regarding the date of the stockholders’ meeting and not to postpone or adjourn the meeting without Viasystems’ consent. Notwithstanding the foregoing, we may postpone or adjourn the stockholders’ meeting, provided that it is not to a date on or after five business days prior to August 15, 2012 (or September 15, 2012 under certain conditions in which matters related to antitrust laws prevent the closing at August 15, 2012), to the extent that:

provided that no postponement or adjournment will be allowed for any such information or disclosure related to an acquisition proposal (including any superior proposal).

We are required to hold the stockholders’ meeting regardless of whether our board of directors withdraws, amends or modifies its recommendation of the merger. Further, we have agreed that our obligation to hold the stockholders’ meeting will not be affected by the commencement, public proposal, public disclosure or communication to us of any acquisition proposal (whether or not a superior proposal). Unless the merger agreement is terminated as provided for therein (as described below), we will not submit any acquisition proposal (whether or not it constitutes a superior proposal) to the vote of our stockholders prior to the vote of our stockholders on the merger.

We have agreed to use reasonable best efforts to obtain any consents, approvals or waivers of third parties with respect to any contracts to which we or any of our subsidiaries is a party as may be necessary or appropriate for the consummation of the transactions contemplated by the merger agreement or required by the terms of any contract as a result of the execution, performance or consummation of transactions contemplated by the merger agreement.

We, Viasystems and merger sub have each agreed, as promptly as practicable and subject to the terms and conditions of the merger agreement, to use our reasonable best efforts to take, or cause to be taken, all other actions and do, or cause to be done, all other things necessary, proper or advisable under applicable law prior to the effective time to consummate the transactions contemplated by the merger agreement, including:

In addition, in connection with the efforts referenced above, each of us, on the one hand, and Viasystems and merger sub, on the other hand, will:

If any objections are asserted with respect to the transactions contemplated by the merger agreement under any antitrust law or if any suit is instituted (or threatened to be instituted) by the Federal Trade Commission, the Department of Justice or any other applicable governmental authority or any private party challenging any of the transactions contemplated by the merger agreement as violative of any antitrust law or which would otherwise prevent, materially impede or materially delay the consummation of the transactions contemplated by the merger agreement, each of Viasystems, merger sub and us will use our reasonable best efforts to resolve any such objections or suits so as to permit consummation of the transactions contemplated by the merger agreement, including in order to resolve such objections or suits which, in any case if not resolved, could reasonably be expected to prevent, materially impede or materially delay the consummation of the transactions contemplated by the merger agreement.

Further, if any objections are asserted with respect to the transactions contemplated by the merger agreement under any antitrust law or if any suit is instituted (or threatened to be instituted) by the Federal Trade

Commission, the Department of Justice or any other applicable governmental authority or any private party challenging any of the transactions contemplated by the merger agreement as violative of any antitrust law, we have agreed that we and our subsidiaries will not, without the prior written consent of Viasystems:

In the event that any administrative or judicial action or proceeding is instituted (or threatened to be instituted) by a governmental authority or private party challenging the merger or any other transaction contemplated by the merger agreement, each of Viasystems, merger sub and us have agreed to cooperate in all respects with each other and use our respective commercially reasonable efforts to contest and resist any such action or proceeding and to have vacated, lifted, reversed or overturned any decree, judgment, injunction or other order, whether temporary, preliminary or permanent, that is in effect and that prohibits, prevents or restricts consummation of the transactions contemplated by the merger agreement. Viasystems will be entitled to direct the antitrust defense of the merger or any other transactions contemplated by the merger agreement, or negotiations with, any governmental authority or other person relating to the merger or regulatory filings under applicable antitrust law, subject to the provisions of the merger agreement.

We have agreed that Viasystems, merger sub and their respective affiliates are not be obligated by the merger agreement to:

From the effective time until the 12 month anniversary of the effective time, Viasystems has agreed to cause the compensation and benefits package provided to our and our subsidiaries’ employees as of the effective time under the plans specified in the disclosure schedule to the merger agreement to be substantially comparable to the compensation and benefits package, in the aggregate, provided to (i) such employees immediately prior to the effective time and (ii) similarly situated employees of Viasystems, in each case excluding for purposes of this comparison any equity-based compensation. However, during such 12-month period, Viasystems or the surviving corporation, as the case may be, may reduce the compensation or benefits of such employees if such reductions in compensation or benefits are made equitably and as part of an across-the-board reduction applicable to all employees within the United States.

From and after the effective time, Viasystems has agreed to cause the surviving corporation to comply in all material respects with its obligations under all employment and severance agreements specified in the disclosure

schedule to the merger agreement that are in effect as of the effective time, in each case, subject to the terms and conditions of each such agreement. Notwithstanding anything herein to the contrary, prior to the closing date, we have agreed to take such actions as are necessary, including making any determinations or adopting resolutions of our board of directors or the compensation committee of our board of directors, as applicable, to amend our 2012 Senior Management Bonus Program in accordance with the provisions set forth in the disclosure schedule to the merger agreement and described above in “DDi 2012 Bonus Program” on page 41.

For purposes of eligibility, vesting and, solely with respect to severance and vacation, level of benefit entitlement (but in no event for purposes of benefit accrual or eligibility for retiree medical or other retiree welfare benefits) under the Viasystems’ employee benefit plans, Viasystems has agreed that each such employee will, subject to applicable law and applicable tax qualification requirements, be credited with his or her years of service with us and our subsidiaries and their respective predecessors before the effective time, to the same extent as such employee was entitled, before the effective time, to credit for such service under any similar plans in which such employee participated or was eligible to participate immediately prior to the effective time; provided, however, that the foregoing shall not apply to the extent that its application would result in a duplication of benefits.

For purposes of each such Viasystems employee benefit plan providing medical, dental, pharmaceutical or vision benefits to any such employee, Viasystems has agreed to use commercially reasonable efforts to cause all pre-existing condition exclusions and actively-at-work requirements of such Viasystems employee benefit plan to be waived, for such employee and his or her covered dependents, unless such conditions would not have been waived under a similar plan in which such employee participated immediately prior to the effective time and Viasystems has agreed to use commercially reasonable efforts to cause any eligible expenses incurred by such employee and his or her covered dependents under the plans during the portion of the plan year of the Viasystems employee benefit plan ending on the date such employee’s participation in the corresponding Viasystems employee benefit plan begins to be taken into account under such Viasystems employee benefit plan, for purposes of satisfying all deductible and maximum out-of-pocket requirements applicable to such employee and his or her covered dependents for the applicable plan year as if such amounts had been paid in accordance with such Viasystems employee benefit plan.

Upon Viasystems’ election, we have agreed that we will terminate, effective as of the day immediately preceding the effective time, any and all 401(k) plans we sponsor or maintain. In such event, we have agreed to provide Viasystems evidence that such plan(s) and/or program(s) have been terminated pursuant to resolutions of our board of directors or a committee thereof (the form and substance of which shall be subject to review and approval of Viasystems), effective as of the day immediately preceding the effective time.

Viasystems’ and merger sub’s obligations to effect the merger are further subject to the satisfaction by us or waiver by them at or prior to the effective time of the following conditions:

Our obligations to effect the merger are subject to the further satisfaction by Viasystems or waiver by us at or prior to the effective time of the following conditions:

The merger agreement may be terminated, the transactions contemplated under the merger agreement may be abandoned, whether before or after obtaining our stockholders’ approval, under the following circumstances:

If the merger agreement is terminated in accordance with the requirements described above, it will become void, and there shall be no liability thereunder on the part of any party hereto, subject to certain exceptions including any obligation to pay the termination fees described below. No such termination, however, will relieve any party hereto from liability for any intentional breach of any of its representations, warranties, covenants or agreements set forth in the merger agreement or fraud prior to such termination.

Each party will generally pay its own fees and expenses in connection with the merger, whether or not the merger is consummated.

Viasystems will be required to pay us a reverse breakup fee of $15.4 million if:

However, in the event the closing does not occur, our right to receive the reverse breakup fee, together with applicable costs of collection, if any, and our right to seek specific performance prior to termination of the merger agreement shall be our exclusive remedies against Viasystems and merger sub for any loss, cost, liability or expenses relating to or arising under the merger agreement or the transactions contemplated hereby, including the failure of Viasystems and merger sub to consummate the transactions contemplated hereby.

In the event we or Viasystems terminate the merger agreement pursuant to the termination provision described above relating to the failure to obtain the stockholder approval after the stockholder meeting (including any adjournment or postponements) has concluded, and after a written bona fide acquisition proposal has been made which our board of directors considered to determine whether it constituted a superior proposal, we will promptly pay to Viasystems all documented out-of-pocket costs and expenses incurred by Viasystems and merger sub in connection with the merger agreement and the transactions contemplated thereunder up to a maximum amount equal to $8 million; provided that in the event such expense reimbursement is paid and a termination fee is thereafter payable pursuant to the sixth bullet above, the termination fee otherwise payable shall be reduced by the amount of such expense reimbursement.

We have agreed to pay the termination fee or expense reimbursement, as applicable, as directed by Viasystems in writing in immediately available funds promptly following (and in any event within two business days after) the date of the event giving rise to the obligation to make such payment. However, if we terminate the merger agreement because we enter into a definitive agreement with respect to a superior proposal, then we must pay the termination fee to Viasystems in immediately available funds in advance or concurrently with such termination. Viasystems has agreed to pay the reverse breakup as we direct in writing in immediately available funds promptly following (and in any event within two business days after) the date of the event giving rise to the obligation to make such payment.

In the event that we fail to pay the termination fee or expense reimbursement required when due, or Viasystems fails to pay the reverse breakup fee when due, such termination fee, expense reimbursement or reverse breakup fee, as the case may be, shall accrue interest for the period commencing on the date when it became past due, at the rate of interest per annum equal to the “Prime Rate” as set forth on such date in The Wall Street Journal “Money Rates” column plus 350 basis points.

In addition, if we fail to pay such termination fee or expense reimbursement, as the case may be, when due, we have agreed pay to Viasystems all of its costs and expenses (including attorneys’ fees) in connection with efforts to collect such termination fee or expense reimbursement. If Viasystems fails to pay the reverse breakup fee when due, Viasystems has agreed to pay all of our costs and expenses (including attorneys’ fees) in connection with efforts to collect such termination reverse breakup fee.

We have also agreed that we, our subsidiaries and the representatives of us and our subsidiaries will not have any rights or claims against any of Viasystems’ financing sources in connection with the transactions contemplated by the merger agreement.

Viasystems has agreed to cause the surviving corporation, to the fullest extent permitted by applicable law, to honor all of our obligations to indemnify and hold harmless each person who is now, or has been at any time prior to the date hereof or who becomes prior to the effective time of the merger an officer or director of us or any of our subsidiaries as provided in our certificate of incorporation or bylaws, or the applicable charter documents of our subsidiary, in each case, as in effect on the date of the merger agreement, or pursuant to any other agreements in effect on the date of the merger agreement, including provisions relating to the advancement of expenses incurred in the defense of any action or as permitted under applicable law.

Viasystems has agreed to purchase or cause the surviving corporation to obtain prior to the effective time of the merger a “tail” officers’ and directors’ liability insurance policy, which by its terms shall survive the merger

and shall provide such directors and officers with coverage for not less than six years following the effective time of the merger on terms and conditions no less favorable than the terms of our current directors’ and officers’ liability insurance policy we currently maintain in respect of actions or omissions of such officers and directors prior to the effective time of the merger in their capacities as such. In no event will Viasystems or the surviving corporation be required to pay more than 200% of the current annual premium paid by us for such policy to purchase the “tail” policy, but if such maximum payment amount is not sufficient to purchase the required coverage, then Viasystems will purchase such lesser coverage as may be obtained with such maximum payment amount.

The obligations of Viasystems and merger sub relating to indemnification and “tail” insurance set forth above will survive the consummation of the merger and will not be terminated or modified in any way that would adversely affect the directors and officers entitled to the protection of these provisions without the consent of such persons. Such person will have the right to enforce these provisions and are express third-party beneficiaries of these provisions for this purpose.

In the event Viasystems or the surviving corporation or any of their respective successors or assigns (i) consolidates with or merges into any other person and is not the continuing or surviving entity of such consolidation or merger or (ii) transfers all or substantially all of its properties and assets to another entity, or if Viasystems dissolves the surviving corporation, then, and in each such case, proper provision shall be made so that the successors and assigns of Viasystems or the surviving corporation, as the case may be, shall assume the obligations set forth above.

Access to Information; Assistance. From the date of the merger agreement hereof until the earlier to occur of the effective time of the merger and the termination of the merger agreement in accordance with its terms, subject to certain exceptions, we have agreed to, and to cause our subsidiaries, our representatives and our subsidiaries’ representatives to:

All such information obtained by Viasystems or merger sub shall be held confidential in accordance with the confidentiality agreement between us and Viasystems, as amended.

Public Announcements. We, Viasystems and merger sub have agreed that no public release or announcement concerning the transactions contemplated by the merger agreement shall be issued by a party without the prior consent of the other parties (which consent shall not be unreasonably withheld, delayed or conditioned), except as would violate applicable law or securities exchange rules, in which case the party required to make the release or announcement shall use its commercially reasonable efforts to allow the other parties reasonable time to comment on such release or announcement in advance of such issuance.

Anti-Takeover Laws. If any anti-takeover law is or may become applicable to any transaction contemplated by the merger agreement, (a) the parties shall use reasonable best efforts to take such actions as are reasonably necessary so that such transactions may be consummated as promptly as practicable on the terms contemplated hereby and (b) our board of directors shall take all actions necessary to render such statutes inapplicable to any such transaction.

Securityholder Litigation. We have agreed to give Viasystems the opportunity to participate in the defense or settlement of any securityholder litigation against us and/or our directors relating to the transactions contemplated by the merger agreement, and no such settlement shall be agreed to without Viasystems’ prior written consent (which consent shall not be unreasonably withheld or delayed).

Notification of Certain Matters. We have agreed to give prompt notice to Viasystems and merger sub and Viasystems and merger sub have agreed to give us prompt notice of:

provided, however, that the delivery of any such notice will not (i) cure any breach of, or non-compliance with, any other provision of the merger agreement or (ii) limit the remedies available to the party receiving such notice.

Specific Performance. We, Viasystems and merger sub are entitled to specific performance of the terms of the merger agreement, without any requirement to post bond, in addition to any other remedy at law or equity. We, Viasystems and merger sub have also agreed not to assert that a remedy of specific enforcement is unenforceable, invalid, contrary to law or inequitable for any reason, or to assert that a remedy of monetary damages would provide an adequate remedy.

SEC Reports. We have agreed to timely file with the SEC all forms, reports, schedules, registration statements, definitive proxy statements and other documents (including all exhibits) required to be filed by us under the Exchange Act or the Securities Act until the effective time of the merger. We have also made other agreements regarding the compliance of such filings with the applicable requirements of the Exchange Act and the Securities Act and the accuracy and completeness of such filings.

We, Viasystems and merger sub may amend the merger agreement at any time prior to the closing of the merger. However, after the adoption of the merger agreement by our stockholders, no amendment can be made without further stockholder approval which, by law or in accordance with applicable securities exchange rules, requires further approval by such stockholders. In addition, certain provisions relating to Viasystems’ financing sources, to the extent affecting such financing sources, may not be amended, modified or waived (including any defined term used therein) without the prior written consent of each of Viasystems’ financing sources participating in a debt offering or, to the extent Viasystems or one of its affiliates has not consummated a debt offering, the bridge financing, as applicable.

We, on the one hand, and Viasystems or merger sub, on the other hand, may (i) extend the time for performance of any of obligation or other act of the other parties under the merger agreement, (ii) waive any inaccuracy in the representations and warranties of the other party contained in the merger agreement or in any document delivered pursuant to the merger agreement and (iii) waive compliance with any agreement of the other party or any condition to its own obligations contained in the merger agreement.

The waiver by any party hereto of a breach of any provision of the merger agreement shall not operate or be construed as a waiver of any prior or subsequent breach of the same or any other provision hereunder. The failure of any party to assert any of its rights under the merger agreement or otherwise shall not constitute a waiver of those rights.

In connection with the execution of the merger agreement, Viasystems entered into voting agreements with the following of our directors and our executive officers in their capacity as DDi stockholders: Robert J. Amman, Gerald P. Barnes, Jay B. Hunt, Andrew E. Lietz, Michael R. Mathews, Lloyd I. Miller, III and certain of his affiliates, Bryant R. Riley, Steven C. Schlepp, Wayne T. Slomsky, Carl R. Vertuca, Jr. and Mikel H. Williams. The following is a summary description of the voting agreements. This summary is not complete and is qualified in its entirety by reference to the complete text of the forms of voting agreement, which are attached to this proxy statement and incorporated into this proxy statement by reference. The form of voting agreement entered into by each of the aforementioned stockholders, other than Mr. Riley, is attached to this proxy statement as Annex C. The voting agreement entered into by Mr. Riley is attached to this proxy statement as Annex D.

Each stockholder who entered into a voting agreement with Viasystems agreed to vote our common stock held by such stockholder at the special meeting:

These stockholders also granted to Viasystems a proxy to vote their shares of our common stock on any of the foregoing matters at the special meeting.

The stockholders signing voting agreements have agreed that they will be bound by non-solicitation restrictions that are similar to the non-solicitation provisions of the merger agreement described above under “The Merger Agreement—Non-Solicitation; Competing acquisition proposals.” These stockholders further agreed:

Not including the shares held by Mr. Riley, approximately 22.6% of the outstanding shares of our common stock on March 30, 2012 were subject to the voting agreements. Mr. Riley held approximately 3.2% of the outstanding shares of our common stock on March 30, 2012.

The following table sets forth information with respect to the beneficial ownership of our common stock as of March 30, 2012 (or such other date as indicated) for:

Beneficial ownership is determined in accordance with the rules of the Securities and Exchange Commission (the “SEC”). Under the rules of the SEC, beneficial ownership includes shares over which the named stockholder exercises voting and/or investment power. Shares and percentages beneficially owned are based upon the number of shares of our common stock outstanding on the record date, together with options that are exercisable for such respective securities within 60 days of the record date for each stockholder. Shares of our common stock subject to options that are currently exercisable or will become exercisable within 60 days of the record date are deemed outstanding for computing the respective percentage ownership of the person holding the option, but are not deemed outstanding for purposes of computing the respective percentage ownership of any other person. The inclusion of shares in the table does not constitute an admission that the named stockholder is a direct or indirect beneficial owner of the shares.

The information as to beneficial ownership presented in the table below does not take into account any accelerated vesting that may occur in connection with the closing of the merger.

In the event that the number of shares of DDi’s common stock present in person and represented by proxy at the special meeting and voting “FOR” the merger is insufficient to adopt the merger agreement, then DDi may move to adjourn the special meeting in order to enable its board of directors to solicit additional proxies in favor of the adoption of the merger agreement provided that such adjournment is not to a date on or after five business days prior to August 15, 2012 (or September 15, 2012 under certain conditions in which matters related to antitrust laws prevent the closing at August 15, 2012). In that event, DDi will ask its stockholders to vote only upon the adjournment proposal and not on the other proposals discussed in this proxy statement.

Whether or not a quorum is present, approval of the proposal to adjourn the special meeting, if necessary or appropriate, for the purpose of soliciting additional proxies requires the affirmative vote of a majority of the shares of DDi common stock present in person or represented by proxy and entitled to vote at the special meeting.

A failure to submit a proxy or to vote in person will have no effect on the adjournment proposal whether or not a quorum is present, although it will have the practical effect of reducing the number of affirmative votes required to achieve the required majority by reducing the total number of shares from which the majority is calculated. An abstention or a broker non-vote will have the effect as if you voted “AGAINST” the adjournment proposal.

DDi’s board of directors unanimously recommends that you vote “FOR” approval of the proposal to adjourn the special meeting, if necessary or appropriate, to solicit additional proxies.

In accordance with Section 14A of the Securities Exchange Act, DDi is providing its stockholders with the opportunity to cast an advisory (non-binding) vote on the compensation that may be paid or become payable to its named executive officers in connection with the proposed merger pursuant to agreements and understandings with DDi, and the agreements and understandings with DDi pursuant to which such compensation may be paid or become payable. As required by those rules, DDi is asking its stockholders to adopt the following resolution:

RESOLVED, that the compensation that may be paid or become payable to DDi’s named executive officers in connection with the merger, as disclosed under the heading “The Merger—Interests of DDi’s Executive Officers and Directors in the Merger” beginning on page 38, is hereby APPROVED.

Compensation that may be paid or become payable to our named executive officers in connection with the merger pursuant to agreements or understandings between our named executive officers and Viasystems is not subject to the advisory vote on merger-related executive compensation but is described under the heading “The Merger—Interests of DDi’s Executive Officers and Directors in the Merger”, beginning on page 38.

The vote on this proposal is a vote separate and apart from the votes on (i) the proposal to adopt the merger agreement or (ii) the proposal to approve adjournments of the special meeting. Accordingly, you may vote to approve either of the other proposals and vote not to approve this proposal on merger-related executive compensation, and vice versa. Approval of this proposal is not a condition to completion of the proposed merger.

Because the vote on merger-related executive compensation is only advisory in nature, it will not be binding on either DDi or Viasystems regardless of whether the proposed merger is completed. Accordingly, as the compensation to be paid in connection with the proposed merger is contractual with respect to the executives, regardless of the outcome of this advisory vote, such compensation will be payable, subject only to the conditions applicable thereto, if the proposed merger is completed.

The vote required to approve this proposal on executive compensation is the affirmative vote of a majority of the shares of DDi common stock present in person or represented by proxy and entitle to vote at the special meeting and casting a vote for or against the matter at the special meeting at which a quorum is present. However, if you are a stockholder of record, and you fail to vote by proxy or by ballot at the special meeting, your shares will not be counted for purposes of determining a quorum.

An abstention, failure to submit a proxy or vote in person or a broker non-vote will have no effect on the proposal regarding the merger-related executive compensation, provided a quorum is present, although they will have the practical effect of reducing the number of affirmative votes required to achieve the required majority by reducing the total number of shares from which the majority is calculated.

DDi’s board of directors unanimously recommends that our stockholders vote “FOR” this proposal.

At this time, we know of no other matters to be submitted at the special meeting. If any other matters properly come before the special meeting, it is the intention of the persons described in the enclosed proxy card to vote the shares they represent as our board of directors may recommend.

It is important that your shares be represented at the special meeting, regardless of the number of shares which you hold. Therefore, we urge you to complete, sign, date and return the accompanying proxy card as promptly as possible in the postage-prepaid envelope enclosed for that purpose or to submit a proxy via the Internet or telephone.

As permitted by the Securities Exchange Act, only one copy of this proxy statement is being delivered to stockholders residing at the same address, unless our stockholders have notified us of their desire to receive multiple copies of the proxy statement. This is known as householding. We will promptly deliver, upon oral or written request, a separate copy of this proxy statement to any stockholder residing at a shared address to which only one copy was mailed. Requests for additional copies of this proxy statement, or requests to receive multiple or single copies of proxy statements at a shared address in the future, should be directed to our proxy solicitor: Mackenzie Partners, Inc. at 1-212-929-5500 (call collect), 1-800-322-2885 (toll free) or proxy@mackenziepartners.com (email).

If the merger is completed, there will be no public participation in any future meetings of stockholders of DDi. However, if the merger is not completed, DDi’s public stockholders will continue to be entitled to attend and participate in our stockholders’ meetings. Proposals of stockholders of DDi intended for inclusion in our proxy statement and proxy card for our 2012 annual meeting of stockholders must have been received by us not later than December 17, 2011. We did not receive any stockholder proposals prior to that date. If a stockholder wished to present a proposal before the 2012 annual meeting but did not wish to have the proposal considered for

inclusion in our proxy statement and proxy in accordance with Rule 14a-8, the stockholder must have delivered written notice us not earlier than February 17, 2012 and not later than March 18, 2012. We did not receive any proposals during that period.

Notwithstanding anything in this Agreement to the contrary, all actions under this Section 3.02 shall be completed in a manner that complies with Section 409A of the Code, and, if applicable, Section 424(a) of the Code.

Section 3.03 Payment of Merger Consideration; Surrender of Company Shares; Stock Transfer Books.

(a) Prior to the Effective Time, Parent or Merger Sub shall appoint as paying agent a bank or trust company reasonably satisfactory to the Company (the “Paying Agent”) to facilitate the receipt by the Company Stockholders of the Merger Consideration in connection with the Merger. Prior to the Effective Time, Parent shall deposit or cause the Surviving Corporation to deposit with the Paying Agent, for the benefit of the holders of Merger Shares, cash in an amount sufficient to pay the aggregate Merger Consideration required to be paid in accordance with this Agreement (such cash being hereinafter referred to as the “Surviving Corporation Fund”). The Surviving Corporation Fund shall not be used for any other purpose.

(b) The Surviving Corporation Fund shall be invested by the Paying Agent as directed by Parent. No gain or loss thereon shall affect the amounts payable to the holders of Merger Shares following completion of the Merger pursuant to this ARTICLE III and Parent shall take all actions necessary to ensure that the Surviving Corporation Fund includes at all times cash sufficient to satisfy Parent’s obligation under this ARTICLE III. Any and all interest and other income earned on the Surviving Corporation Fund shall promptly be paid to Parent or an Affiliate of Parent as directed by Parent.

(c) As promptly as practicable after the Effective Time, Parent and the Surviving Corporation shall cause the Paying Agent to mail to each Person who was, as of immediately prior to the Effective Time, a holder of record of the Merger Shares (i) a letter of transmittal (which shall be in customary form approved by the Company and shall specify that delivery shall be effected, and risk of loss and title to the certificates representing the Merger Shares (the “Company Share Certificates”) or uncertificated Merger Shares represented by book entry (“Uncertificated Shares”) shall pass, only upon proper delivery of the Company Share Certificates or transfer of the Uncertificated Shares to the Paying Agent) and (ii) instructions for effecting the surrender of the Company Share Certificates or transfer of the Uncertificated Shares in exchange for the Merger Consideration.

(d) Upon (i) surrender to the Paying Agent of Company Share Certificates for cancellation, together with such letter of transmittal, duly completed and validly executed in accordance with the instructions thereto, and such other documents as may be required pursuant to such instructions or (ii) compliance with the reasonable procedures established by the Paying Agent for delivery of Uncertificated Shares, the holder of such Company Share Certificates or Uncertificated Shares shall be entitled to receive in exchange therefor, in cash, the aggregate Merger Consideration in respect thereof, and the Company Share Certificates or Uncertificated Shares so surrendered shall forthwith be cancelled. No interest shall be paid or will accrue on any cash payable to holders of Company Share Certificates or Uncertificated Shares pursuant to the provisions of this ARTICLE III.

(e) In the event of a transfer of ownership of Merger Shares that is not registered in the transfer records of the Company, payment of the Merger Consideration in respect of the applicable Merger Shares may be made to a Person other than the Person in whose name the Company Share Certificates so surrendered or the Uncertificated Shares so transferred is registered if such Company Share Certificates shall be properly endorsed or otherwise be in proper form for transfer or such Uncertificated Shares shall be properly transferred and the Person requesting such payment shall pay any transfer Tax or other Taxes required by reason of the payment of the Merger Consideration in respect thereof or establish to the reasonable satisfaction of the Surviving Corporation that such Tax has been paid or is not applicable. Until surrendered or transferred, as the case may be, as contemplated by this Section 3.03, each Company Share Certificate or Uncertificated Share shall be deemed at all times after the Effective Time to represent only the right to receive upon such surrender the Merger Consideration.

(f) If any Company Share Certificate shall have been lost, stolen or destroyed, upon the making of an affidavit of that fact by the Person claiming such Company Share Certificate to be lost, stolen or destroyed and, if required by the Surviving Corporation, the posting by such Person of a bond, in such reasonable amount as the Surviving Corporation may direct, as indemnity against any claim that may be made against it with respect to such Company Share Certificate, the Paying Agent shall pay in respect of Merger Shares to which such lost, stolen or destroyed Company Share Certificate relates the Merger Consideration to which the holder thereof is entitled.

(g) At the Effective Time, the stock transfer books of the Company shall be closed and there shall be no further registration of transfers of Merger Shares thereafter on the records of the Company. From and after the Effective Time, the holders of Company Share Certificates or Uncertificated Shares shall cease to have any rights with respect to such shares, except as otherwise provided in this Agreement, the certificate of incorporation of the Surviving Corporation or by applicable Law.

(h) Any portion of the Surviving Corporation Fund that remains undistributed to the holders of Merger Shares for six months after the Effective Time shall be delivered to the Surviving Corporation, upon demand, and any holders of Merger Shares who have not theretofore complied with this ARTICLE III shall thereafter look only to the Surviving Corporation for, and the Surviving Corporation shall remain liable for, payment of their claim for the Merger Consideration (and Parent shall take all actions necessary to ensure that the Surviving Corporation has or has access to sufficient funds to make such payments). Any portion of the Surviving Corporation Fund remaining unclaimed by holders of Merger Shares as of a date which is immediately prior to such time as such amounts would otherwise escheat to or become property of any Governmental Authority shall, to the extent permitted by applicable Law, become the property of the Surviving Corporation free and clear of any claims or interest of any Person previously entitled thereto. None of Parent, the Paying Agent or the Surviving Corporation shall be liable to any holder of Merger Shares for any such shares (or dividends or distributions with respect thereto) or cash delivered to a public official pursuant to any abandoned property, escheat or similar Law.

(a) Notwithstanding anything in this Agreement to the contrary, Company Shares that are outstanding immediately prior to the Effective Time and that are held by any Company Stockholder who shall have neither voted in favor of the Merger nor consented thereto in writing and who shall have demanded properly in writing appraisal for such Company Shares in accordance with Section 262 of the DGCL (collectively, the “Dissenting Shares”) shall not be converted into the right to receive the Merger Consideration as provided in Section 3.01(b), but rather, the holders of Dissenting Shares shall be entitled only to payment of the appraised value of such Dissenting Shares in accordance with the provisions of Section 262 of the DGCL (and, at the Effective Time, such Dissenting Shares shall no longer be outstanding and shall automatically be cancelled and shall cease to exist, and such holders shall cease to have any right with respect thereto, except the right to receive the appraised value of such Dissenting Shares in accordance with the provisions of Section 262 of the DGCL); provided, however, that if any such holder shall fail to perfect or otherwise shall waive, withdraw or lose the right to appraisal under the provisions of Section 262 of the DGCL, then the right of such holder to be paid the appraised value of such holder’s Dissenting Shares shall cease and such Dissenting Shares shall be deemed to have been converted as of the Effective Time into, and to have become exchangeable solely for, the right to receive the Merger Consideration, without interest, as provided in Section 3.01(b).

(b) The Company shall notify Parent as promptly as reasonably practicable of any demands received by the Company for appraisal of any Company Shares, withdrawals thereof and any other instruments delivered to the Company pursuant to Section 262 of the DGCL, and Parent shall have the right to participate in all negotiations and proceedings with respect to such demands. Prior to the Effective Time, the Company shall not, without the prior written consent of Parent, voluntarily make any payment with respect to, or settle or offer to settle, any such demands, or agree to do any of the foregoing. Any portion of the Merger Consideration made available to the Paying Agent pursuant to Section 3.03(a) to pay for Dissenting Shares shall be returned to Parent upon demand.

Section 3.05 Withholding Rights. Notwithstanding anything in this Agreement to the contrary, the Company, the Surviving Corporation, Parent, Merger Sub and the Paying Agent, as applicable, shall be entitled to deduct and withhold from the Merger Consideration and any other payment otherwise payable pursuant to this Agreement to any holder of Company Shares or Company Stock Options, as applicable, such amounts as it is required to deduct and withhold with respect to the making of such payment under the Code or any provision of state, local or foreign Tax Law. To the extent that amounts are so withheld or paid over to or deposited with the relevant Governmental Authority, including any Tax authority, such amounts shall be treated for all purposes of this Agreement as having been paid to the holder of the Company Shares in respect of which such deduction and withholding was made by the Company, the Surviving Corporation, Parent, Merger Sub or the Paying Agent, as applicable.

Section 3.06 Adjustments to Prevent Dilution. In the event that the Company changes (or establishes a record date for changing) the number of Company Shares issued and outstanding prior to the Effective Time as a result of a stock split, stock dividend, recapitalization, subdivision, reclassification, combination, exchange of shares or similar transaction with respect to the outstanding Company Shares, at any time during the period from the date hereof to the Effective Time, the Merger Consideration shall be equitably adjusted to reflect such transaction; provided, however, that nothing in this Section 3.06 shall be construed as permitting the Company to take any action or enter into any transaction otherwise prohibited by this Agreement.

The Proxy Statement will not contain or incorporate by reference any statement which, at the time the Proxy Statement is filed with the SEC, at the time the Proxy Statement is first sent to the Company Stockholders or at the time of the Company Stockholders’ Meeting, and in the light of the circumstances under which it is made, is false or misleading with respect to any material fact, or which omits to state any material fact necessary in order to make the statements therein not false or misleading or necessary to correct any statement in any earlier communication with respect to the solicitation of a proxy for the Company Stockholders’ Meeting or the subject matter thereof which shall have become false or misleading; provided, however, that no representation or warranty is made by the Company with respect to information supplied by or on behalf of Parent or Merger Sub for inclusion in the Proxy Statement.

No other “fair price,” “moratorium,” “control share acquisition” or other anti-takeover statute or regulation of any Governmental Authority (each, an “Anti-Takeover Law”) is applicable to the Company or the Transactions.

Parent and Merger Sub hereby jointly and severally represent and warrant to the Company as follows:

Section 5.01 Organization. Each of Parent and Merger Sub is a corporation duly organized, validly existing and in good standing under the Laws of the jurisdiction of its incorporation. Each of Parent and Merger Sub (a) is duly qualified or licensed to do business as a foreign corporation and is, to the extent applicable, in good standing under the Laws of any other jurisdiction in which the character of the properties owned, leased or operated by it therein or in which the transaction of its business makes such qualification or licensing necessary and (b) has the requisite corporate power and authority to own, operate and lease its properties and assets and carry on its business as now conducted, except where the failure to be so qualified, licensed or in good standing or have such corporate power and authority would not reasonably be expected to have a Parent Material Adverse Effect.

Section 5.02 Ownership of Merger Sub; No Prior Activities. Merger Sub was formed solely for the purpose of engaging in the Transactions, has not engaged in any business activities or conducted any operations other than in connection with the Transactions and will have no assets, liabilities or obligations other than those contemplated by this Agreement. All the issued and outstanding shares of capital stock of Merger Sub are, and as of the Effective Time will be, owned of record and beneficially by Parent either directly or indirectly through one or more of its Subsidiaries.

Section 5.03 Authority; Validity and Effect of Agreements. Each of Parent and Merger Sub has all requisite corporate power and authority to execute and deliver this Agreement and all other agreements and documents contemplated hereby to which it is a party, and to perform its obligations hereunder and thereunder and to consummate the Transactions. Other than the adoption of the Merger by Parent (or one or more Subsidiaries of Parent) as the stockholder or stockholders of Merger Sub (which will be effected immediately following execution of this Agreement), the execution, delivery and performance by each of Parent and Merger Sub of this Agreement and the consummation of the Transactions have been duly and validly authorized by all requisite corporate action on behalf of each of Parent and Merger Sub and no other corporate proceedings on the part of either of Parent and Merger Sub are necessary to authorize this Agreement or to consummate the Transactions. This Agreement has been duly and validly executed and delivered by Parent and Merger Sub and, assuming due authorization, execution and delivery by the Company, constitutes a legal, valid and binding obligation of each of Parent and Merger Sub enforceable against each of Parent and Merger Sub in accordance with its terms, subject to the Bankruptcy and Equity Exception.

(a) The execution and delivery by each of Parent and Merger Sub of this Agreement and all other agreements and documents contemplated hereby to which it is a party and the consummation by each of Parent

and Merger Sub of the Transactions do not and will not, directly or indirectly (with or without notice or lapse of time or both), and the compliance by each of Parent and Merger Sub with its obligations hereunder and thereunder will not, directly or indirectly (with or without notice or lapse of time or both), (i) result in a violation or breach of or conflict with the certificate of incorporation, bylaws or other organizational documents of either of Parent or Merger Sub, (ii) subject to obtaining or making the consents, approvals, Orders, authorizations, registrations, declarations, filings and other actions described in Section 5.04(b) below, conflict with or violate any Law applicable to Parent or Merger Sub or by which any property or asset of Parent or Merger Sub is bound, (iii) result in a violation or breach or conflict with any provision of, or constitute (with or without notice or lapse of time, or both) a default under, any of the terms, conditions or provisions of any Contract to which Parent, Merger Sub or any of their respective Subsidiaries is a party or by which any of their respective properties or assets may be bound or (iv) result in the creation of a Lien on any property or asset of Parent or Merger Sub or any of their respective Subsidiaries, except, with respect to clauses (ii), (iii) and (iv), as would not reasonably be expected to have a Parent Material Adverse Effect.

(b) No consent, approval, Order or authorization of, or registration, qualification, designation or filing with or notification to, any Governmental Authority is required on the part of any of Parent and Merger Sub in connection with the execution, delivery and performance of this Agreement or the consummation by Parent and Merger Sub of the Transactions, other than (i)(A) the applicable requirements of the Exchange Act and state securities, takeover and “blue sky” Laws, (B) the applicable requirements of NASDAQ, (C) the HSR Act and the applicable requirements of other Antitrust Laws and (D) the filing with the Secretary of State of the State of Delaware of the Certificate of Merger pursuant to the DGCL and (ii) such other consents, approvals, Orders, authorizations, registrations, qualifications, designations, filings or notifications that, if not obtained, made or given, would not reasonably be expected to have a Parent Material Adverse Effect.

Section 5.05 Proxy Statement. The information supplied by Parent for inclusion in the Proxy Statement, if any, will comply as to form and substance in all material respects with the applicable requirements of the Exchange Act and the rules and regulations thereunder. The information supplied by Parent and Merger Sub for inclusion in the Proxy Statement, if any, will not contain any statement which, at the time the Proxy Statement is first sent to the Company Stockholders, at the time of any amendment or supplement thereof, or at the time of the Company Stockholders’ Meeting, and in the light of the circumstances under which it is made, is false or misleading with respect to any material fact, or which omits to state any material fact necessary in order to make the statements therein not false or misleading or necessary to correct any statement in any earlier communication with respect to the solicitation of a proxy for the Company Stockholders’ Meeting or the subject matter thereof which shall have become false or misleading. Notwithstanding the foregoing, Parent and Merger Sub make no representation or warranty with respect to any information supplied by or on behalf of the Company for inclusion in the Proxy Statement.

Section 5.06 Absence of Litigation. There is no Action pending or threatened in writing against Parent or any of its Subsidiaries or any of their respective properties or assets, except as would not reasonably be expected to have a Parent Material Adverse Effect. Neither Parent nor any of its Subsidiaries is subject to any Order of any Governmental Authority, except as would not reasonably be expected to have a Parent Material Adverse Effect.

Section 5.07 State Takeover Statutes. None of Parent, Merger Sub or any other affiliate of Parent has been an “interested stockholder” (as such term is used in Section 203 of DGCL) with respect to the Company at any time within three years of the date of this Agreement.

Parent has provided to the Company a true and correct copy of a commitment letter, dated April 3, 2012, executed and delivered by Goldman Sachs Bank, USA, WF Investment Holdings, LLC, Wells Fargo Securities, LLC and Stifel Financial Corporation (such commitment letter, together with any amendments or supplements thereto or replacements thereof obtained by Parent from time to time, the “Commitment Letter”) with respect to all debt financing required for consummation of the Transactions (the “Bridge Financing”). The amount of the Bridge Financing provides sufficient funds for Parent and Merger Sub to

The Company shall respond promptly in good faith to any comments by the SEC and if, at any time prior to the Effective Time, any event or information relating to the Company, Parent, Merger Sub, or any of their Affiliates should be discovered by Parent or the Company which should be set forth in an amendment or supplement to the Proxy Statement, so that such document would not include any misstatement of a material fact or omit to state any material fact necessary to make the statements therein not false or misleading, the party that discovers such information shall promptly notify the other parties and the Company shall cause an appropriate amendment or supplement describing such information to be filed with the SEC as promptly as practicable thereafter and, to the extent required by applicable Law or Order, disseminated to the Company Stockholders.

(c) The Company shall take all actions necessary in accordance with applicable Law, Orders and the Company Certificate and the Company Bylaws (i) to duly call, give notice of, convene and hold a special meeting of its stockholders as promptly as practicable, and in any event (to the extent permissible under applicable Law and Orders) as soon as practicable following the mailing of the definitive Proxy Statement to the stockholders of the Company (but in no event later than 30 calendar days following the date of such mailing), for the purpose of considering the adoption of this Agreement (the “Company Stockholders’ Meeting”) and (ii) unless the Company Board shall have effected an Adverse Recommendation Change in accordance with Section 6.05(d), (A) include in the Proxy Statement the Company Board’s recommendation that the holders of the Company Shares vote in favor of the adoption of this Agreement (which recommendation shall be deemed a part of the Company Board Recommendation) and (B) use its reasonable best efforts to solicit from the Company Stockholders proxies in favor of the adoption of this Agreement and secure the vote or consent of the Company Stockholders as required by the rules of NASDAQ, the DGCL or other applicable Law to effect the Merger. The Company shall give Parent no less than 10 Business Days’ advance notice (or such shorter period of time as notice is provided to NASDAQ) of the date which shall be set as the “record date” for the Company Stockholders eligible to vote on this Agreement and the Transactions. The Company shall consult with Parent regarding the date of the Company Stockholders’ Meeting and shall not postpone or adjourn the Company Stockholders’ Meeting without the prior written consent of Parent; provided, however, that nothing herein shall prevent the Company from postponing or adjourning the Company Stockholders’ Meeting if and to the extent that: (i) there are holders of an insufficient number of Company Shares present or represented by a proxy at the Company Stockholders’ Meeting to constitute a quorum at the Company Stockholders’ Meeting and the Company uses its reasonable best efforts during any such postponement or adjournment to obtain such a quorum as soon as practicable, (ii) the Company is required to postpone or adjourn the Company Stockholders’ Meeting by applicable Law or Order or a request from the SEC or its staff and the Company uses its reasonable best efforts to hold or resume the Company Stockholders’ Meeting as soon as practicable, or (iii) the Company Board shall have determined in good faith (after consultation with outside legal counsel and Parent) that it is required by Law to postpone or adjourn the Company Stockholders’ Meeting, including in order to give Company Stockholders sufficient time to evaluate any information or disclosure that the Company has sent to the Company Stockholders or otherwise made available to the Company Stockholders by issuing a press release or filing materials with the SEC; provided that (A) the preceding clause (iii) shall not apply to allow a postponement or adjournment for any information or disclosure related to an Acquisition Proposal (including any Superior Proposal) and (B) no postponement or adjournment may be to a date on or after five Business Days prior to the Outside Date.

(d) The Company shall ensure that the Company Stockholders’ Meeting is called, noticed, convened, held and conducted, and that all Persons solicited in connection with the Company Stockholders’ Meeting are solicited, in compliance with all applicable Law and Orders. The adoption of this Agreement and adjournment of the Company Stockholders’ Meeting, as necessary, to solicit additional proxies if there are insufficient votes in favor of adoption of this Agreement shall be the only matters which the Company shall propose to be acted on by the Company Stockholders at the Company Stockholders’ Meeting unless otherwise approved in writing by Parent.

(e) Without limiting the generality of the foregoing, the Company agrees that (i) its obligation to duly call, give notice of, convene and hold the Company Stockholders’ Meeting shall not be affected by the

withdrawal, amendment or modification of the Company Board Recommendation and (ii) its obligations pursuant to this Section 6.03 shall not be affected by the commencement, public proposal, public disclosure or communication to the Company of any Acquisition Proposal (whether or not a Superior Proposal). Unless this Agreement is terminated in accordance with Section 8.01, the Company agrees that it shall not submit to the vote of the stockholders of the Company any Acquisition Proposal (whether or not a Superior Proposal) prior to the vote of the Company Stockholders with respect to the Merger at the Company Stockholders’ Meeting.

(a) Subject to applicable Laws relating to the exchange of information, from the date hereof until the earlier to occur of the Effective Time and the termination of this Agreement in accordance with its terms, the Company shall, and shall cause its Subsidiaries and the Representatives of the Company and its Subsidiaries to, afford Parent, Merger Sub and Parent’s financing sources and their respective Representatives reasonable access during normal working hours upon reasonable advance notice to the officers, employees, agents, assets, properties, offices, plants and other facilities, books and records of the Company and each of its Subsidiaries and shall timely furnish Parent, Merger Sub and Parent’s financing sources with such financial, operating, business, financial condition, projections and other data and information as Parent, Merger Sub or Parent’s financing sources, through their Representatives, may reasonably request, including furnishing all historical financial statements and historical financial and other data of the type and form customarily included in offering documents used in private placements under Rule 144A of the Securities Act. The Company shall, and shall cause its Subsidiaries and the Representatives of the Company and its Subsidiaries to, provide to Parent and its financing sources information which is complete and correct in all material respects and does not and will not, when taken as a whole, contain any untrue statement of a material fact or omit to state a material fact necessary to make the statements contained therein, in the light of the circumstances under which such statements are made, not misleading. The Company hereby consents to the use of all of its and its Subsidiaries’ logos in connection with the Debt Offering and the Bridge Financing. Without limiting the generality of the foregoing, from the date hereof until the earlier to occur of the Effective Time and the termination of this Agreement in accordance with its terms, the Company shall, and shall cause its Subsidiaries and the Representatives of the Company and its Subsidiaries to, provide to Parent all cooperation reasonably necessary, proper or advisable in connection with Parent’s financing of the Transactions, including using commercially reasonable efforts with respect to (i) executing and delivering at Closing any pledge and security documents, other definitive financing documents or other certificates or documents as may be reasonably requested by Parent (including a certificate of an appropriate officer of the Company or any of its Subsidiaries with respect to solvency matters and consents of accountants for use of their reports in any materials relating to Parent’s financing of the Transactions), (ii) obtaining accountants’ comfort letters (including comfort letters customary in similar types of Transactions for pro forma financial information and related adjustments), legal opinions, and, at Parent’s expense, surveys and title insurance as reasonably requested by Parent, (iii) taking all actions reasonably necessary to (A) permit Parent’s financing sources to evaluate the Company’s and its Subsidiaries’ current assets, cash management and accounting systems, policies and procedures relating thereto and (B) establish bank and other accounts and blocked account agreements and lock box arrangements, (iv) if requested by any of Parent’s financial sources, providing authorization letters to Parent’s financing sources containing a representation, without any knowledge or like qualifier, that information contained in any confidential information memorandum and/or lender presentation does not include material non public information about the Company, its Subsidiaries, or their respective Affiliates or their respective securities, (v) if requested by any of Parent’s financing sources, designating whether any information provided to Parent’s financing sources is suitable to be made available to lenders who wish not to receive material non-public information and (vi) taking all corporate actions necessary to permit the consummation of Parent’s financing of the Transactions and to permit the proceeds thereof to be made available as of the Closing Date. Notwithstanding the foregoing, under no circumstance shall the Company or its Subsidiaries be required to authorize the pre-filing of any UCC-1’s or other documents which create Liens.

(b) Any investigation conducted pursuant to the access contemplated by this Section 6.04 shall be conducted in a manner that does not unreasonably interfere with the conduct of the business of the Company and

its Subsidiaries or damage or destroy any property or assets of the Company or any of its Subsidiaries. All information obtained by Parent or Merger Sub pursuant to this Section 6.04 shall be held confidential in accordance with the Confidentiality Agreement, dated September 9, 2010, as amended by the letter agreement dated as of March 12, 2012 (the “Confidentiality Agreement”), between Parent and the Company; provided, that nothing herein or in the Confidentiality Agreement shall prevent Parent or its financing sources from using all information obtained pursuant to this Section 6.04 as necessary and appropriate to consummate a Debt Offering and Bridge Financing.

(c) After the date hereof, Parent and the Company shall cooperate to establish a mechanism acceptable to both parties by which Parent will be permitted, prior to the Effective Time or the Termination Date, as the case may be, and subject to applicable Law, to communicate directly with the Company employees regarding employee related matters.

(a) The Company shall, and shall cause its Subsidiaries and Representatives to, immediately cease and terminate, or cause to be terminated, any and all discussions, solicitations, encouragements or negotiations with any Person conducted heretofore with respect to an Acquisition Proposal and shall promptly request (or, to the extent the Company is contractually permitted to do so, require) the return or destruction of all copies of confidential information previously provided to such parties by or on behalf of the Company, its Subsidiaries or Representatives. From the date of this Agreement until the earlier of the Effective Time or the termination of this Agreement in accordance with Section 8.01, subject to Section 6.05(b), the Company shall not, and shall cause its Subsidiaries and Representatives not to, directly or indirectly, (i) solicit, initiate, cause, knowingly facilitate or encourage (including by way of furnishing information) the submission of any inquiries, proposals or offers or any other efforts or attempts that constitute or may reasonably be expected to lead to any Acquisition Proposal, or engage in any discussions or negotiations with respect thereto or otherwise cooperate with or assist or participate in, or knowingly facilitate or encourage, any such inquiries, proposals, discussions or negotiations, or resolve to or publicly propose to take any of the foregoing actions, (ii) approve or recommend, or resolve to or publicly propose to approve or recommend, any Acquisition Proposal or enter into any merger agreement, agreement-in-principle, letter of intent, share purchase agreement, asset purchase agreement, share exchange agreement, option agreement or other similar agreement relating to an Acquisition Proposal or enter into any letter of intent, agreement or agreement-in-principle requiring the Company (whether or not subject to conditions) to abandon, terminate or fail to consummate the Merger or (iii) (A) withdraw, modify or qualify in a manner adverse to Parent or Merger Sub the Company Board Recommendation or the approval or declaration of advisability by the Company Board of this Agreement and the Transactions (including the Merger) or (B) approve or recommend, or resolve to or publicly propose to approve or recommend, any Acquisition Proposal (any action described in clause (A) or (B) being referred to as an “Adverse Recommendation Change”).

(b) Notwithstanding anything to the contrary contained in Section 6.05(a), if at any time following the date of this Agreement and prior to the Effective Time, (i) the Company has received from a third party a written, bona fide Acquisition Proposal, (ii) a breach by the Company of this Section 6.05 has not contributed to the making of such Acquisition Proposal, (iii) the Company Board determines in good faith, after consultation with its financial advisors and outside counsel, that such Acquisition Proposal constitutes or is reasonably likely to lead to a Superior Proposal and (iv) after consultation with its outside counsel, the Company Board determines in good faith that failure to take such action would constitute a breach by the Company Board of its fiduciary duties to the Company Stockholders under applicable Law, then the Company may, subject to clauses (x), (y) and (z) below, (A) furnish confidential information with respect to the Company and its Subsidiaries to the Person making such Acquisition Proposal and (B) participate in discussions or negotiations with the Person making such Acquisition Proposal regarding such Acquisition Proposal; provided, however, that the Company (x) will not, and will not allow its Representatives to, disclose any non-public information to such Person unless the Company first enters into an Acceptable Confidentiality Agreement with such Person, (y) will promptly (and in any event within 24 hours) provide to Parent notice of its intention to enter into such Acceptable Confidentiality Agreement and (z) will promptly (and in any event within 24 hours) provide to Parent any and all non-public information delivered to such Person which was not previously provided to Parent.

(c) From and after the date of this Agreement and prior to the Effective Time, the Company shall promptly (and in any event within 24 hours) notify Parent, orally and in writing, in the event that the Company or any of its Subsidiaries or Representatives receives (i) any Acquisition Proposal or indication by any Person that it is considering making an Acquisition Proposal, (ii) any request for non-public information in contemplation of an Acquisition Proposal relating to the Company or any of its Subsidiaries or (iii) any inquiry or request for discussions or negotiations regarding any Acquisition Proposal. The Company shall provide Parent promptly (and in any event within 24 hours) with the identity of such Person and a copy of such Acquisition Proposal, indication, inquiry or request (or, where such Acquisition Proposal is not in writing, a written description of the Company’s understanding of the material terms and conditions of such Acquisition Proposal, indication, inquiry or request), including any modifications thereto. The Company shall keep Parent informed (orally and in writing) on a current basis (and in any event no later than 24 hours after the occurrence of any material changes, developments, discussions or negotiations) of the status of any Acquisition Proposal, indication, inquiry or request (including the material terms and conditions thereof and of any material modification thereto), and any developments, discussions and negotiations, including furnishing copies of any written inquiries, correspondence and draft documentation, and written summaries of any material oral inquiries or discussions. Without limiting the foregoing, the Company shall promptly (and in any event within 24 hours) notify Parent orally and in writing if it determines to begin providing information or to engage in discussions or negotiations concerning an Acquisition Proposal in accordance with Section 6.05(b) and shall in no event begin providing such information or engaging in such discussions or negotiations prior to providing such notice. The Company shall not, and shall cause its Subsidiaries and Representatives not to, enter into any Contract with any Person subsequent to the date of this Agreement that would restrict the Company’s ability to provide such information relating to the Company or any of its Subsidiaries to Parent, and neither the Company nor any of its Subsidiaries is currently party to any Contract that prohibits the Company from providing the information relating to the Company or any of its Subsidiaries described in this Section 6.05(c) to Parent. The Company (i) shall not, and shall cause its Subsidiaries not to, terminate, waive, amend or modify any provision of, or grant permission or request under, any standstill or confidentiality agreement to which it or any of its Subsidiaries is or becomes a party and (ii) shall, and shall cause its Subsidiaries to, use reasonable best efforts to enforce the provisions of any such agreement.

(d) Notwithstanding anything in Section 6.05(a) to the contrary, if (i) the Company receives from a third party a written, bona fide Acquisition Proposal, (ii) a breach by the Company of this Section 6.05 has not contributed to the making of such Acquisition Proposal and (iii) the Company Board determines in good faith, after consultation with its financial advisors and outside counsel, that such Acquisition Proposal constitutes a Superior Proposal after giving effect to all of the adjustments to the terms of this Agreement which may be offered by Parent, including pursuant to clause (III) below, the Company Board may at any time prior to the Effective Time, if it determines in good faith, after consultation with its outside counsel, that failure to take such action would constitute a breach by the Company Board of its fiduciary duties to the Company Stockholders under applicable Law, (x) effect an Adverse Recommendation Change and/or (y) terminate this Agreement to enter into a definitive agreement with respect to such Superior Proposal; provided, however, that the Company shall not terminate this Agreement pursuant to the foregoing clause (y), and any purported termination pursuant to the foregoing clause (y) shall be void and of no force or effect, unless in advance of or concurrently with such termination the Company (A) pays the Termination Fee to Parent in immediately available funds and (B) concurrently with such termination enters into the Alternative Acquisition Agreement; provided, further, however, that the Company Board may not effect an Adverse Recommendation Change pursuant to the foregoing clause (x) or terminate this Agreement pursuant to the foregoing clause (y) unless (I) the Company shall not have breached this Section 6.05, (II) the Company shall have provided prior written notice to Parent, at least five Business Days in advance (the “Notice Period”), of its intention to take such action with respect to such Superior Proposal, which notice shall specify the material terms and conditions of any such Superior Proposal (including the identity of the party making such Superior Proposal), and shall have contemporaneously provided to Parent a copy of any proposed definitive agreement(s) with respect to such Superior Proposal (the “Alternative Acquisition Agreement”), (III) prior to effecting such Adverse Recommendation Change or terminating this Agreement to enter into an Alternative Acquisition Agreement with respect to such Superior Proposal, the

Company shall, and shall cause its financial advisors and outside counsel to, during the Notice Period, negotiate with Parent in good faith (to the extent Parent desires to negotiate) to make such adjustments in the terms and conditions of this Agreement so that such Acquisition Proposal ceases to constitute a Superior Proposal and (IV) following any negotiation described in the immediately preceding clause (III), such Acquisition Proposal (provided that the Company shall have complied with the provisions of the immediately following sentence) continues to constitute a Superior Proposal. In the event of any material revisions to the terms of an Acquisition Proposal after the start of the Notice Period, the Company shall be required to deliver a new written notice to Parent and to comply with the requirements of this Section 6.05(d) with respect to such new written notice, and the Notice Period shall be deemed to have re-commenced on the date of such new notice.

(e) The Company agrees that any violations of the restrictions set forth in this Section 6.05 by any of its Representatives shall be deemed to be a material breach of this Agreement (including this Section 6.05) by the Company.

(f) Nothing contained in this Section 6.05 shall prohibit the Company Board from taking and disclosing to the Company Stockholders a position contemplated by Rule 14e-2(a), Rule 14d-9 or Item 1012(a) of Regulation M-A promulgated under the Exchange Act; provided, however, that any disclosure other than (i) a “stop, look and listen” or similar communication of the type contemplated by Rule 14d-9(f) under the Exchange Act, (ii) an express rejection of any applicable Acquisition Proposal or (iii) an express reaffirmation of the Company Board Recommendation together with a factual description of events or actions leading up to such disclosure that have been taken by the Company and that are permitted under Section 6.05 or actions taken or notices delivered to Parent by the Company that are required by Section 6.05, shall, in each case, be deemed to be an Adverse Recommendation Change (including for purposes of Section 8.01(f)).

(g) The Company shall not take any action to exempt any Person (other than Parent, Merger Sub and their respective Affiliates) from the provisions of “control share acquisitions” contained in any Anti-Takeover Law or otherwise cause such restrictions not to apply, in each case unless such actions are taken simultaneously with a termination of this Agreement pursuant to Section 8.01(h).

(a) From the Effective Time until the 12 month anniversary of the Effective Time, Parent shall cause the compensation and benefits package provided to the employees of the Company and its Subsidiaries as of the Effective Time under the Plans listed on Section 4.12(a) of the Disclosure Schedule (the “Company Employees”) to be substantially comparable to the compensation and benefits package, in the aggregate, provided to (i) the Company Employees immediately prior to the Effective Time and (ii) similarly situated Parent employees, in each case excluding for purposes of this comparison any equity-based compensation; provided, however, that during such 12-month period, Parent or the Surviving Corporation, as the case may be, may reduce the compensation or benefits of such Company Employees if such reductions in compensation or benefits are made equitably and as part of an across-the-board reduction applicable to all employees within the United States.

(b) From and after the Effective Time, Parent shall cause the Surviving Corporation to comply in all material respects with its obligations under all employment and severance agreements listed on Section 4.12(a) of the Disclosure Schedule that are in effect as of the Effective Time, in each case, subject to the terms and conditions of each such agreement. Notwithstanding anything herein to the contrary, prior to the Closing Date, the Company shall take such actions as are necessary, including making any determinations or adopting resolutions of the Company Board or the compensation committee of the Company Board, as applicable, to amend the 2012 Senior Management Bonus Program in accordance with the provisions set forth in Section 6.06(b) of the Disclosure Schedule.

(c) For purposes of eligibility, vesting and, solely with respect to severance and vacation, level of benefit entitlement (but in no event for purposes of benefit accrual or eligibility for retiree medical or other

retiree welfare benefits) under the Parent Plans, each Company Employee shall, subject to applicable Law and applicable Tax qualification requirements, be credited with his or her years of service with the Company and its Subsidiaries and their respective predecessors before the Effective Time, to the same extent as such Company Employee was entitled, before the Effective Time, to credit for such service under any similar Plans in which such Company Employee participated or was eligible to participate immediately prior to the Effective Time; provided, however, that the foregoing shall not apply to the extent that its application would result in a duplication of benefits.

(d) For purposes of each Parent Plan providing medical, dental, pharmaceutical or vision benefits to any Company Employee, Parent shall use commercially reasonable efforts to cause all pre-existing condition exclusions and actively-at-work requirements of such Parent Plan to be waived for such Company Employee and his or her covered dependents, unless such conditions would not have been waived under a similar Plan in which such Company Employee participated immediately prior to the Effective Time and Parent shall use commercially reasonable efforts to cause any eligible expenses incurred by such employee and his or her covered dependents under the Plans during the portion of the plan year of the Parent Plan ending on the date such employee’s participation in the corresponding Parent Plan begins to be taken into account under such Parent Plan for purposes of satisfying all deductible and maximum out-of-pocket requirements applicable to such employee and his or her covered dependents for the applicable plan year as if such amounts had been paid in accordance with such Parent Plan.

(e) At Parent’s election, the Company shall terminate, effective as of the day immediately preceding the Effective Time, any and all 401(k) Plans sponsored or maintained by the Company. In such event, Parent shall receive from the Company evidence that the Company’s Plan(s) and/or program(s) have been terminated pursuant to resolutions of the Company Board or a committee thereof (the form and substance of which shall be subject to review and approval of Parent), effective as of the day immediately preceding the Effective Time.

(f) Notwithstanding the foregoing, nothing contained in this Section 6.06 shall (i) be treated as an amendment of any particular Plan, (ii) give any third party any right to enforce the provisions of this Section 6.06 or (iii) require Parent or any of its Affiliates to (A) maintain any particular Plan or (B) retain the employment of any particular employee.

(g) The Company will take all actions necessary to effectuate the provisions of Section 6.06(g) of the Disclosure Schedule.

Section 6.07 Directors’ and Officers’ Indemnification and Insurance of the Surviving Corporation.

(a) To the fullest extent permitted by applicable Law, Parent shall cause the Surviving Corporation to honor all of the Company’s obligations to indemnify and hold harmless each person who is now, or has been at any time prior to the date hereof or who becomes prior to the Effective Time an officer or director of the Company or any of its Subsidiaries (each an “Indemnified Party”) as provided in the Company Certificate or Company Bylaws, in each case, as in effect on the date of this Agreement, or pursuant to any other agreements in effect on the date hereof, accurate and complete copies of which have been provided to Parent and are listed in Section 6.07(a) of the Disclosure Schedule, including provisions relating to the advancement of expenses incurred in the defense of any Action or as permitted under applicable Law. Parent’s obligation under this Section 6.07(a) shall survive the Merger and shall remain in full force and effect for a period of not less than six years after the Effective Time. During such period, Parent shall guarantee the obligations of the Surviving Corporation with respect to any and all amounts payable under this Section 6.07.

(b) In addition to Parent’s indemnification obligations pursuant to Section 6.07(a) above, prior to the Effective Time, Parent shall, or shall cause the Surviving Corporation to, purchase a “tail” officers’ and directors’ liability insurance policy, which by its terms shall survive the Merger and shall provide each Indemnified Party with coverage for not less than six years following the Effective Time on terms and conditions

no less favorable than the terms of the directors’ and officers’ liability insurance policy currently maintained by the Company (a correct and complete copy of which has been delivered to Parent) (the “D&O Insurance”) in respect of actions or omissions of such officers and directors prior to the Effective Time in their capacities as such; provided, however, that in no event shall Parent or the Surviving Corporation be required to expend more than 200% of the current annual premium paid by the Company for such policy to purchase the “tail” policy (the “Maximum Amount”); provided, further, however, that if the amount of the annual premiums necessary to procure such insurance coverage exceeds the Maximum Amount, Parent shall spend up to the Maximum Amount to purchase such lesser coverage as may be obtained with such Maximum Amount. The Indemnified Parties may be required to make reasonable application and provide reasonable and customary representations and warranties to applicable insurance carriers for the purpose of obtaining such insurance.

(c) The obligations of Parent and the Surviving Corporation under this Section 6.07 shall survive the consummation of the Merger and shall not be terminated or modified in such a manner as to adversely affect any Indemnified Party to whom this Section 6.07 applies without the consent of such affected Indemnified Party (it being expressly agreed that the Indemnified Parties to whom this Section 6.07 applies shall be third party beneficiaries of this Section 6.07, each of whom may enforce the provisions of this Section 6.07).

(d) If Parent or the Surviving Corporation or any of their respective successors or assigns (i) consolidates with or merges into any other Person and shall not be the continuing or Surviving Corporation or entity of such consolidation or merger or (ii) transfers all or substantially all of its properties and assets to any Person, then, and in each such case, proper provision shall be made so that the successors and assigns of Parent or the Surviving Corporation, as the case may be, shall assume the obligations set forth in this Section 6.07.

(a) Except to the extent Parent (or an Affiliate of Parent) has completed a debt securities financing, bank loan financing or other debt financing in lieu of, or whose net cash proceeds fully replace amounts that were to be provided under the Bridge Financing as contemplated by and pursuant to the Commitment Letter and the other letters related thereto (such an offering, a “Debt Offering”), subject to the terms and conditions of this Agreement, Parent shall use its reasonable best efforts to obtain and effectuate the Bridge Financing contemplated by the Commitment Letter on the terms set forth therein (including, without limitation, any impact on such terms of provisions existing in the Fee Letter (as defined in the Commitment Letter)). Except to the extent Parent (or an Affiliate of Parent) has completed a Debt Offering, Parent agrees to notify the Company as soon as reasonably practicable if, at any time prior to the Closing Date, (i) the Commitment Letter shall expire or be terminated for any reason, (ii) any financing source that is a party to the Commitment Letter notifies Parent that such source no longer intends to provide financing to Parent or (iii) for any reason Parent no longer believes in good faith that it will be able to obtain any of the Bridge Financing substantially on the terms described in the Commitment Letter. Other than in connection with a Debt Offering, Parent shall not, nor shall it permit any of its subsidiaries or Affiliates to, without the prior written consent of the Company, take any action or enter into any transaction, including, without limitation, any merger, acquisition, joint venture, disposition, lease, contract or debt or equity financing that would reasonably be expected to materially impair, delay or prevent the Bridge Financing contemplated by the Commitment Letter. Other than in connection with a Debt Offering, neither Parent nor Merger Sub shall amend or alter, or agree to amend or alter, the Commitment Letter in any manner that would materially impair, delay or prevent the Closing without the prior written consent of the Company. Notwithstanding any provision of this Agreement to the contrary, in no event shall Parent or Merger Sub be required to consummate the Closing prior to the earlier of (i) the third Business Day immediately following consummation of a Debt Offering and (ii) the Outside Date.

(b) Except to the extent Parent has completed a Debt Offering, if the Commitment Letter shall expire or terminate for any reason, Parent shall use its reasonable best efforts to obtain, and will provide the Company with a copy of, a new financing commitment that provides for a sufficient amount of financing for Parent to consummate the Transactions on funding conditions not materially less favorable than those included in the

Commitment Letter as originally issued and other terms and conditions the aggregate effect of which is not materially adverse to Parent in comparison with those contained in the Commitment Letter as originally issued, which extension or new commitment shall include a termination date not earlier than the Outside Date. Parent shall accept any such commitment letter if the funding conditions and other terms and conditions contained therein are not materially adverse to Parent in comparison with those contained in the Commitment Letter as originally issued.

(a) Prior to the Effective Time, the Company shall use its reasonable best efforts to obtain any consents, approvals or waivers of third parties with respect to any Contracts to which the Company or any of its Subsidiaries is a party as may be necessary or appropriate for the consummation of the Transactions or required by the terms of any Contract as a result of the execution, performance or consummation of the Transactions. Subject to the terms and conditions of this Agreement, prior to the Effective Time, each of the Company, Parent and Merger Sub shall, as promptly as practicable, use its reasonable best efforts to take, or cause to be taken, all other actions and do, or cause to be done, all other things necessary, proper or advisable under applicable Law to consummate the Transactions. In furtherance and not in limitation of the foregoing, each of the Company, Parent and Merger Sub shall (i) make all appropriate filings and submissions (and filings and submissions considered by Parent to be advisable) under the HSR Act and with any other Governmental Authority pursuant to any other applicable Antitrust Laws or otherwise, as promptly as practicable, but in no event later than 10 Business Days after the date hereof with respect to filing under the HSR Act, and shall make as promptly as practicable any other appropriate submissions under other applicable Antitrust Laws, (ii) use commercially reasonable efforts to obtain as promptly as practicable the termination of any waiting period under the HSR Act and any applicable foreign Antitrust Laws, (iii) cooperate and consult with each other in (A) determining which filings are required to be made prior to the Effective Time with, and which material consents, approvals, permits, notices or authorizations are required to be obtained prior to the Effective Time from, Governmental Authorities in connection with the execution and delivery of this Agreement and related agreements and consummation of the transactions contemplated hereby and thereby and (B) timely making all such filings and timely seeking all such consents, approvals, permits, notices or authorizations.

(b) In connection with the efforts referenced in Section 6.09(a), each of the Company, on the one hand, and Parent and Merger Sub, on the other hand, will (i) cooperate in all respects with each other in connection with any filing or submission and in connection with any investigation or other inquiry, including any proceeding initiated by a private party, (ii) keep the other party reasonably informed of any communication received by such party from, or given by such party to, the Federal Trade Commission (the “FTC”), the Antitrust Division of the Department of Justice (the “DOJ”) or any other U.S. or foreign Governmental Authority and of any communication received or given in connection with any proceeding by a private party, in each case regarding the Transactions and (iii) permit the other party to review any communication given by it to, and consult with each other in advance of any meeting or conference with, the FTC, the DOJ or any other Governmental Authority or, in connection with any proceeding by a private party, with any other Person, and to the extent permitted by the FTC, the DOJ or such other applicable Governmental Authority or other Person, give the other party the opportunity to attend and participate in such meetings and conferences.

(c) In furtherance and not in limitation of the covenants of the parties contained in Section 6.09(a) and Section 6.09(b), if any objections are asserted with respect to the Transactions under any Antitrust Law or if any suit is instituted (or threatened to be instituted) by the FTC, the DOJ or any other applicable Governmental Authority or any private party challenging any of the Transactions as violative of any Antitrust Law or which would otherwise prevent, materially impede or materially delay the consummation of the Transactions, each of Parent, Merger Sub and the Company shall use its reasonable best efforts to resolve any such objections or suits so as to permit consummation of the Transactions, including in order to resolve such objections or suits which, in any case if not resolved, could reasonably be expected to prevent, materially impede or materially delay the consummation of the Transactions.

Actions or claims commenced or, to such party’s knowledge, threatened against, relating to or involving or otherwise affecting such party or any of its Subsidiaries that relate to the Transactions, (d) the discovery of any fact or circumstance, or the occurrence or non-occurrence of any event, that would cause any representation or warranty made by such party contained in this Agreement to be, with respect to the Company, untrue or inaccurate such that the condition set forth in Section 7.02 would not be satisfied, and with respect to Parent and Merger Sub, untrue or inaccurate in any material respect, and (e) any material failure of such party to comply with or satisfy any covenant or agreement to be complied with or satisfied by it hereunder; provided, however, that the delivery of any notice pursuant to this Section 6.13 shall not (i) cure any breach of, or non-compliance with, any other provision of this Agreement or (ii) limit the remedies available to the party receiving such notice.

Section 8.02 Effect of Termination. In the event of the termination of this Agreement pursuant to Section 8.01, this Agreement shall forthwith become void, and there shall be no liability under this Agreement on the part of any party hereto except that the provisions of the last sentence of Section 6.04(a), this Section 8.02, Section 8.03 and ARTICLE IX shall survive any such termination; provided, however, that, except as set forth in Section 8.03(b)(iii), nothing herein shall relieve any party hereto from liability for any intentional breach of any of its representations, warranties, covenants or agreements set forth in this Agreement or fraud prior to such termination.

(a) Except as otherwise set forth in this Section 8.03, all expenses incurred in connection with this Agreement shall be paid by the party incurring such expenses, whether or not the Merger is consummated.

(iii) (A) by the Company pursuant to Section 8.01(b) and (B) at the time of termination all of the conditions to Closing set forth in ARTICLE VII (other than those other conditions that, by their nature, cannot be satisfied until the Closing Date, but which conditions would be satisfied if the Closing Date were the date of such termination) have been satisfied or waived on or prior to the Outside Date, then Parent shall pay to the Company the Reverse Breakup Fee. Notwithstanding anything to the contrary contained in this Agreement, in the event the Closing does not occur, the Company’s right to receive the Reverse Breakup Fee pursuant to this Section 8.03(b)(iii), together with applicable costs of collection, if any, payable pursuant to Section 8.03(d)(ii), and the Company’s right to seek specific performance prior to termination of the Agreement pursuant to Section 9.05 shall be the exclusive remedies of the Company against Parent and Merger Sub for any loss, cost, liability or expenses relating to or arising under this Agreement or the transactions contemplated hereby, including the failure of Parent and Merger Sub to consummate the transactions contemplated hereby.

(c) In the event this Agreement shall be terminated by Parent or the Company pursuant to Section 8.01(e) after a Bona Fide Proposal shall have been made, the Company shall promptly pay to Parent all documented out-of-pocket costs and expenses incurred by Parent and Merger Sub in connection with this Agreement and the Transactions up to a maximum amount equal to $8,000,000.00 (the “Expense

Reimbursement”); provided that in the event the Expense Reimbursement is paid and a Termination Fee is thereafter payable pursuant to Section 8.03(b)(ii), the Termination Fee otherwise payable shall be reduced by the amount of the Expense Reimbursement.

(d) The Company, Parent and Merger Sub each acknowledge that the agreements contained in this Section 8.03 are an integral part of the Agreement and the Transactions and that, without these agreements, the other parties hereto would not enter into this Agreement.

(i) Except with respect to Section 8.01(h), in which case the Termination Fee shall be paid by the Company in accordance with Section 6.05(d), the Termination Fee or Expense Reimbursement, as applicable, shall be paid by the Company as directed by Parent in writing in immediately available funds promptly following (and in any event within two Business Days after) the date of the event giving rise to the obligation to make such payment. In the event that the Company shall fail to pay the Termination Fee or Expense Reimbursement required pursuant to this Section 8.03 when due, such Termination Fee or Expense Reimbursement, as the case may be, shall accrue interest for the period commencing on the date such Termination Fee and/or Expense Reimbursement, as the case may be, became past due, at the rate of interest per annum equal to the “Prime Rate” as set forth on the date such payment became past due in The Wall Street Journal “Money Rates” column plus 350 basis points. In addition, if the Company shall fail to pay such Termination Fee or Expense Reimbursement, as the case may be, when due, the Company shall also pay to Parent all of Parent’s costs and expenses (including attorneys’ fees) in connection with efforts to collect such Termination Fee or Expense Reimbursement, as the case may be.

(ii) The Reverse Breakup Fee shall be paid by Parent as directed by the Company in writing in immediately available funds promptly following (and in any event within two Business Days after) the date of the event giving rise to the obligation to make such payment.

In addition, if Parent shall fail to pay such Reverse Breakup Fee when due, Parent shall also pay to the Company all of the Company’s costs and expenses (including attorneys’ fees) in connection with efforts to collect such Reverse Breakup Fee.

(e) The Company, its Subsidiaries and the Representatives of the Company and its Subsidiaries shall not have any rights or claims against any Parent financing source in connection with the Transactions, including the Bridge Financing or any Debt Offering, whether at law or equity, in contract, in tort or otherwise.

Section 8.04 Amendment. This Agreement may be amended by the parties hereto by action taken by their respective boards of directors (or similar governing bodies or entities) at any time prior to the Effective Time; provided, however, that, after Company Stockholder Approval has been obtained, no amendment may be made without further stockholder approval which, by Law or in accordance with the rules of NASDAQ, requires further approval by such stockholders. This Agreement may not be amended except by an instrument in writing signed by the parties hereto. Notwithstanding the foregoing, the provisions of Section 6.04(a), Section 8.03(d), Section 8.04, Section 9.06, Section 9.07 and Section 9.08, to the extent affecting any of the Parent’s financing sources, may not be amended, modified or waived (including any defined term used therein) without the prior written consent of each of Parent’s financing sources participating in a Debt Offering or, to the extent Parent or an Affiliate of Parent has not consummated a Debt Offering, the Bridge Financing, as applicable.

Section 8.05 Waiver. At any time prior to the Effective Time, the Company, on the one hand, and Parent and Merger Sub, on the other hand, may (a) extend the time for the performance of any obligation or other act of the other party, (b) waive any inaccuracy in the representations and warranties of the other party contained herein or in any document delivered pursuant hereto and (c) waive compliance with any agreement of the other party or any condition to its own obligations contained herein. Any such extension or waiver shall be valid if set forth in an instrument in writing signed by the Company or Parent (on behalf of Parent and Merger Sub). The waiver by

any party hereto of a breach of any provision hereunder shall not operate or be construed as a waiver of any prior or subsequent breach of the same or any other provision hereunder. The failure of any party to assert any of its rights under this Agreement or otherwise shall not constitute a waiver of those rights.

Section 9.01 Non-Survival of Representations and Warranties. The representations and warranties in this Agreement and in any certificate delivered pursuant hereto shall terminate at the Effective Time.

Section 9.02 Notices. All notices, requests, claims, demands and other communications hereunder shall be in writing and shall be given (and shall be deemed to have been duly given upon receipt) by delivery in person, by prepaid overnight courier (providing proof of delivery), by facsimile, by email or by registered or certified mail (postage prepaid, return receipt requested) to the respective parties at the following addresses, facsimile numbers or email addresses (or at such other address for a party as shall be specified in a notice given in accordance with this Section 9.02):

Section 9.03 Severability. If any term or other provision of this Agreement is invalid, illegal or incapable of being enforced by any rule of Law or public policy or the application of this Agreement to any Person or circumstance is invalid or incapable of being enforced by any rule of Law or public policy, all other conditions and provisions of this Agreement shall nevertheless remain in full force and effect so long as the economic or legal substance of the Transactions is not affected in any manner materially adverse to any party. To such end, the provisions of this Agreement are agreed to be severable. Upon such determination that any term or other provision is invalid, illegal or incapable of being enforced, the parties hereto shall negotiate in good faith to modify this Agreement so as to effect the original intent of the parties hereto as closely as possible in a mutually acceptable manner in order that the Transactions be consummated as originally contemplated to the fullest extent possible.

Section 9.04 Entire Agreement; Assignment. This Agreement, together with the Confidentiality Agreement and the Disclosure Schedule, constitute the entire agreement among the parties with respect to the subject matter hereof, and supersede all prior agreements and undertakings, both written and oral, among the parties, or any of them, with respect to the subject matter hereof. Notwithstanding the forgoing, the Company acknowledges and agrees that, upon execution of this Agreement, each of Parent’s potential financing sources shall be considered a Representative (as defined in the Confidentiality Agreement) of Parent for all purposes under the Confidentiality Agreement. This Agreement shall not be assigned, whether pursuant to a merger, by operation of law or otherwise; provided that Merger Sub may assign, in its sole discretion, any or all of its rights, interests and obligations under this Agreement to any wholly-owned subsidiary of Parent without the consent of the Company.

Section 9.05 Specific Performance. The parties hereto agree that irreparable damage would occur in the event any provision of this Agreement were not performed in accordance with the terms hereof and that money damages would not be a sufficient remedy for any breach of this Agreement, and accordingly, the parties hereto shall be entitled to specific performance of the terms hereof, without any requirement to post bond, in addition to any other remedy at law or equity. The parties hereto further agree not to assert that a remedy of specific enforcement is unenforceable, invalid, contrary to law or inequitable for any reason, nor to assert that a remedy of monetary damages would provide an adequate remedy.

Section 9.06 Parties in Interest. This Agreement shall be binding upon and inure solely to the benefit of each party hereto, and nothing in this Agreement, express or implied, is intended to or shall confer upon any other Person any right, benefit or remedy of any nature whatsoever under or by reason of this Agreement, other than the provisions of Section 6.07 (which are intended to be for the benefit of the Persons covered thereby or the Persons entitled to payment thereunder and may be enforced by such Persons). Notwithstanding the foregoing, Parent’s financing sources are intended third party beneficiaries under Section 6.04(a), Section 6.04(b), Section 8.03(d), Section 8.04, Section 9.07 and Section 9.08.

(a) All disputes, claims or controversies arising out of or relating to this Agreement, or the negotiation, validity or performance of this Agreement, or the Transactions shall be governed by and construed in accordance with the laws of the State of Delaware without regard to its rules of conflict of laws.

(b) All Actions arising out of or relating to this Agreement shall be heard and determined in the Court of Chancery of the State of Delaware (or, only if the Court of Chancery of the State of Delaware declines to accept jurisdiction over a particular matter, any federal court within the State of Delaware). The parties hereby (i) submit to the exclusive jurisdiction of the Court of Chancery of the State of Delaware (or, only if the Court of Chancery of the State of Delaware declines to accept jurisdiction over a particular matter, any federal court within the State of Delaware) for the purpose of any Action arising out of or relating to this Agreement brought by any party and (ii) irrevocably waive, and agree not to assert by way of motion, defense, or otherwise, in any such Action, any claim that it is not subject personally to the jurisdiction of the above-named courts, that its property is exempt or immune from attachment or execution, that any such Action is brought in an inconvenient

forum, that the venue of such Action is improper, or that this Agreement or the Transactions may not be enforced in or by any of the above-named courts. Each of the parties hereto agrees that mailing of process or other papers in connection with any action or proceeding in the manner provided in Section 9.02 or such other manner as may be permitted by Law shall be valid and sufficient service of process.

(c) Notwithstanding anything herein to the contrary, the Company and its Subsidiaries agree (i) that any Action involving a Parent financing source in connection with the Transactions, including Actions involving the Bridge Financing or any Debt Offering, shall be brought exclusively in any Federal court of the United States of America sitting in the Borough of Manhattan or, if that court does not have subject matter jurisdiction, in any state court located in the City and County of New York and each of the Company, its Subsidiaries and the Representatives of the Company and its Subsidiaries submits for itself and its property with respect to any such action to the exclusive jurisdiction of such courts, (ii) not to bring or permit any of its Affiliates to bring or support anyone else in bringing any such Action in any other court, (iii) that service of process, summons, notice or document by registered mail addressed to it at its address provided in Section 9.02 shall be effective service of process against it for any such action brought in any such court, (iv) to waive and hereby irrevocably waives, to the fullest extent permitted by law, any objection which it may now or hereafter have to the laying of venue of, and the defense of an inconvenient forum to the maintenance of, any such Action in any such court, (v) that a final judgment in any such Action shall be conclusive and may be enforced in other jurisdictions by suit on the judgment or in any other manner provided by law, (vi) that any such Action shall be governed by, and construed in accordance with, the laws of the State of New York and (vii) to irrevocably waive and hereby waives any right to a trial by jury in any such action to the same extent such rights are waived pursuant to this Section 9.08.

Section 9.08 Waiver of Jury Trial. EACH OF THE PARTIES HERETO HEREBY WAIVES TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW ANY RIGHT IT MAY HAVE TO A TRIAL BY JURY WITH RESPECT TO ANY LITIGATION DIRECTLY OR INDIRECTLY ARISING OUT OF, UNDER OR IN CONNECTION WITH THIS AGREEMENT OR THE TRANSACTIONS. Each of the parties (a) certifies that no representative, agent or attorney of any other party has represented, expressly or otherwise, that such other party would not, in the event of litigation, seek to enforce that foregoing waiver and (b) acknowledges that it and the other hereto have been induced to enter into this Agreement and the Transactions, as applicable, by, among other things, the mutual waivers and certifications in this Section 9.08.

Section 9.09 Counterparts. This Agreement may be executed and delivered (including by facsimile or other form of electronic transmission) in two or more counterparts, and by the different parties hereto in separate counterparts, each of which when executed shall be deemed to be an original but all of which taken together shall constitute one and the same agreement.

IN WITNESS WHEREOF, Parent, Merger Sub and the Company have caused this Agreement to be executed as of the date first written above by their respective officers thereunto duly authorized.

We understand that DDi Corp. (the “Company”), Viasystems Group, Inc. (“Parent”), and Victor Merger Sub Corp., a wholly-owned subsidiary of Parent (“Merger Sub”), propose to enter into an Agreement and Plan of Merger (the “Merger Agreement”), pursuant to which Merger Sub will merge with and into the Company (the “Merger”) in a transaction in which each outstanding share of common stock, par value $0.001 per share, of the Company (the “Common Stock”), other than shares of Common Stock held in the treasury of the Company or owned, directly or indirectly, by a wholly-owned subsidiary of the Company, Parent or Merger Sub, all of which shares will be canceled, or as to which dissenters rights have been properly exercised, will be converted into the right to receive $13.00 in cash (the “Consideration”). The terms and conditions of the Merger are more fully set forth in the Merger Agreement.

You have asked for our opinion as to whether the Consideration to be received by the holders of shares of Common Stock pursuant to the Merger Agreement is fair, from a financial point of view, to such holders.

In our review and analysis and in rendering this opinion, we have assumed and relied upon, but have not assumed any responsibility to independently investigate or verify, the accuracy and completeness of all financial and other information that was supplied or otherwise made available by the Company or that was publicly available (including, without limitation, the information described above), or that was otherwise reviewed by us. We have relied on assurances of the management of the Company that it is not aware of any facts or circumstances that would make such information inaccurate or misleading. In our review, we did not obtain any independent evaluation or appraisal of any of the assets or liabilities of, nor did we conduct a physical inspection of any of the properties or facilities of, the Company, nor have we been furnished with any such evaluations or appraisals, nor do we assume any responsibility to obtain any such evaluations or appraisals.

With respect to the financial forecasts provided to and examined by us, we note that projecting future results of any company is inherently subject to uncertainty. The Company has informed us, however, and we have assumed, that such financial forecasts were reasonably prepared on bases reflecting the best currently available estimates and good faith judgments of the management of the Company as to the future financial performance of the Company. We express no opinion as to the Company’s financial forecasts or the assumptions on which they are made.

Our opinion is based on economic, monetary, regulatory, market and other conditions existing and which can be evaluated as of the date hereof. We expressly disclaim any undertaking or obligation to advise any person of any change in any fact or matter affecting our opinion of which we become aware after the date hereof.

We have made no independent investigation of any legal or accounting matters affecting the Company, and we have assumed the correctness in all respects material to our analysis of all legal and accounting advice given to the Company and its Board of Directors, including, without limitation, advice as to the legal, accounting and tax consequences of the terms of, and transactions contemplated by, the Merger Agreement to the Company and its stockholders. In addition, in preparing this opinion, we have not taken into account any tax consequences of the transaction to any holder of Common Stock. We have assumed that the final form of the Merger Agreement will be substantially similar to the last draft reviewed by us. We have also assumed that in the course of obtaining the necessary regulatory or third party approvals, consents and releases for the Merger, no delay, limitation, restriction or condition will be imposed that would have an adverse effect on the Company, Parent or the contemplated benefits of the Merger.

It is understood that our opinion is for the use and benefit of the Board of Directors of the Company in its consideration of the Merger, and our opinion does not address the relative merits of the transactions contemplated by the Merger Agreement as compared to any alternative transaction or opportunity that might be available to the Company, nor does it address the underlying business decision by the Company to engage in the Merger or the terms of the Merger Agreement or the documents referred to therein. Our opinion does not constitute a recommendation as to how any holder of shares of Common Stock should vote on the Merger or any matter related thereto. In addition, you have not asked us to address, and this opinion does not address, the fairness to, or any other consideration of, the holders of any class of securities, creditors or other constituencies of the Company, other than the holders of shares of Common Stock. We express no opinion as to the price at which shares of Common Stock will trade at any time. Furthermore, we do not express any view or opinion as to the fairness, financial or otherwise, of the amount or nature of any compensation payable or to be received by any of the Company’s officers, directors or employees, or any class of such persons, in connection with the Merger relative to the Consideration to be received by holders of shares of Common Stock. Our opinion has been authorized by the Fairness Committee of Jefferies & Company, Inc.

We have been engaged by the Company to act as financial advisor to the Company in connection with the Merger and will receive a fee for our services, a portion of which is payable upon delivery of this opinion and a significant portion of which is payable contingent upon consummation of the Merger. We also will be reimbursed for expenses incurred. The Company has agreed to indemnify us against liabilities arising out of or in connection with the services rendered and to be rendered by us under such engagement. We maintain a market in the securities of the Company, and in the ordinary course of our business, we and our affiliates may trade or hold securities of the Company or Parent and/or their respective affiliates for our own account and for the accounts of our customers and, accordingly, may at any time hold long or short positions in those securities. In addition, we may seek to, in the future, provide financial advisory and financing services to the Company, Parent or entities that are affiliated with the Company or Parent, for which we would expect to receive compensation. Except as otherwise expressly provided in our engagement letter with the Company, our opinion may not be used or referred to by the Company, or quoted or disclosed to any person in any manner, without our prior written consent.

Based upon and subject to the foregoing, we are of the opinion that, as of the date hereof, the Consideration to be received by the holders of shares of Common Stock pursuant to the Merger Agreement is fair, from a financial point of view, to such holders.

Subject to the preceding sentence, this Agreement shall be binding upon and inure to the benefit of the parties hereto and their respective permitted successors and permitted assigns.

If any term or other provision of this Agreement is invalid, illegal or incapable of being enforced by any rule of Law or public policy or the application of this Agreement to any Person or circumstance is invalid or incapable of being enforced by any rule of Law or public policy, all other conditions and provisions of this Agreement shall nevertheless remain in full force and effect so long as the economic or legal substance of the transactions contemplated hereby is not affected in any manner materially adverse to any party. To such end, the provisions of this Agreement are agreed to be severable. Upon such determination that any term or other provision is invalid, illegal or incapable of being enforced, the parties hereto shall negotiate in good faith to modify this Agreement so as to effect the original intent of the parties hereto as closely as possible in a mutually acceptable manner in order that the transactions contemplated hereby be consummated as originally contemplated to the fullest extent possible.

(i) All disputes, claims or controversies arising out of or relating to this Agreement, or the negotiation, validity or performance of this Agreement, or the Transactions contemplated hereby shall be governed by and construed in accordance with the laws of the State of Delaware without regard to its rules of conflict of laws.

(ii) All Actions arising out of or relating to this Agreement shall be heard and determined in the Court of Chancery of the State of Delaware (or, only if the Court of Chancery of the State of Delaware declines to accept jurisdiction over a particular matter, any federal court within the State of Delaware). The parties hereby (A) submit to the exclusive jurisdiction of the Court of Chancery of the State of Delaware (or, only if the Court of Chancery of the State of Delaware declines to accept jurisdiction over a particular matter, any federal court within the State of Delaware) for the purpose of any Action arising out of or relating to this Agreement brought by any party and (B) irrevocably waive, and agree not to assert by way of motion, defense, or otherwise, in any such Action, any claim that it is not subject personally to the jurisdiction of the above-named courts, that its property is exempt or immune from attachment or execution, that the Action is brought in an inconvenient forum, that the venue of the Action is improper, or that this Agreement or the Transactions may not be enforced in or by any of the above-named courts. Each of the parties hereto agrees that mailing of process or other papers in connection with any action or proceeding in the manner provided in Section 12(a) or such other manner as may be permitted by Law shall be valid and sufficient service of process.

(iii) Waiver of Jury Trial. EACH OF THE PARTIES HERETO HEREBY WAIVES TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW ANY RIGHT IT MAY HAVE TO A TRIAL BY JURY WITH RESPECT TO ANY LITIGATION DIRECTLY OR INDIRECTLY ARISING OUT OF, UNDER OR IN CONNECTION WITH THIS AGREEMENT OR THE TRANSACTIONS. Each of the parties (A) certifies that no representative, agent or attorney of any other party has represented, expressly or otherwise, that such other party would not, in the event of litigation, seek to enforce that foregoing waiver and (B) acknowledges that it and the other hereto have been induced to enter into this Agreement and the transactions contemplated hereby, as applicable, by, among other things, the mutual waivers and certifications in this Section 12(f).

(g) Counterparts.

(h) Expenses. All costs and expenses incurred in connection with this Agreement shall be paid by or on behalf of the party incurring such cost or expense.

(i) Headings. The Section headings contained in this Agreement are inserted for convenience only and shall not affect in any way the meaning or interpretation of this Agreement.

Any reference to any national, state, local or foreign Law shall be deemed also to refer to all rules and regulations promulgated thereunder, unless the context otherwise requires. When a reference is made in this Agreement to Sections or Schedules, such reference shall be to a Section of or Schedule to this Agreement unless otherwise indicated. Whenever the words “include,” “includes” or “including” are used in this Agreement, they shall be deemed to be followed by the words “without limitation.” In this Agreement, the Voting Stockholder of any Company Shares held in trust shall be deemed to be the relevant trust and/or the trustees thereof acting in their capacities as such trustees, in each case as the context may require to be most protective of Parent, including for purposes of such trustees’ representations and warranties as to the proper organization of the trust, their power and authority as trustees and the non-contravention of the trust’s governing instruments.

(k) No Presumption. This Agreement shall be construed without regard to any presumption or rule requiring construction or interpretation against the party drafting or causing any instrument to be drafted.

(l) Specific Performance. The Voting Stockholder agrees that irreparable damage would occur in the event any provision of this Agreement were not performed by him or it in accordance with the terms hereof and that money damages would not be a sufficient remedy for any breach of this Agreement, and accordingly, Parent shall be entitled to specific performance of the terms hereof, without any requirement to post bond, in addition to any other remedy at law or equity.

(m) No Limitation on Actions as Director. Notwithstanding any other provision of this Agreement, nothing in this Agreement is intended to, or shall be construed to, prohibit the Voting Stockholder, or any officer or Affiliate of the Voting Stockholder who is a director of the Company, from taking any action in his capacity as a member of the Company Board or from exercising his fiduciary duties as a member of the Company Board.

IN WITNESS WHEREOF, the parties hereto have caused this Agreement to be executed by their duly authorized respective officers as of the date first written above.

Section 2. Certain Agreements of the Voting Stockholder. The Voting Stockholder shall not, and shall not permit its Affiliates or any of his or its or their respective Representatives to, take any other action that would make any representation or warranty of the Voting Stockholder contained herein untrue or incorrect in any material respect or in any way restrict, limit or interfere in any material respect with the performance of the Voting Stockholder’s obligations hereunder or the Transactions.

For the avoidance of doubt, nothing in this Agreement shall prevent or impair, or be deemed to prevent or impair, the ability of the Voting Stockholder to Transfer any Company Shares beneficially owned by him or it as of the date of this Agreement or acquired thereafter. For purposes of this Agreement, “Transfer” shall mean the sale, transfer, pledge, hypothecation, encumbrance, assignment or disposition of Company Shares, rights relating thereto or the beneficial ownership of Company Shares or rights relating thereto, the offer to make such a sale, transfer, pledge, hypothecation, encumbrance, assignment or disposition, and each option, agreement, arrangement or understanding, whether or not in writing, to effect any of the foregoing; provided that during the Agreement Period the Voting Stockholder shall not Transfer any Company Shares to any Person that, to the actual knowledge of the Voting Stockholder, has made or intends to make an Acquisition Proposal. As a verb, “Transfer” shall have a correlative meaning. Notwithstanding anything in this Agreement to the contrary, no provision of this Agreement shall cover or apply to or be deemed to cover or apply to any Company Shares beneficially owned by RIP Select 20, LLC.

Section 3. Voting of Subject Shares. During the Agreement Period, the Voting Stockholder undertakes that (a) at such time as the Company conducts a meeting of, or otherwise seeks a vote or consent of, the Company Stockholders, the Voting Stockholder shall, or shall cause any Affiliate that is the holder of record on any applicable record date to, vote the Subject Shares beneficially owned by the Voting Stockholder as of the applicable record or consent date in favor of, or provide a consent with respect to, (i) adoption of the Merger Agreement and each of the other Transactions, (ii) approval of any proposal to adjourn or postpone any meeting of Company Stockholders to a later date if there are not sufficient votes for the adoption of the Merger Agreement on the date on which such meeting is held and (iii) any other matter necessary for consummation of the Transactions that is considered at any such meeting or is the subject of any such consent solicitation and (b) at each meeting of Company Stockholders and in connection with each consent solicitation, the Voting Stockholder shall, or shall cause any Affiliate that is the holder of record on any applicable record date to, vote the Subject Shares beneficially owned by the Voting Stockholder as of the applicable record or consent date against, and not provide consents with respect to, (i) any agreement or arrangement related to or in furtherance of any Acquisition Proposal, (ii) any liquidation, dissolution, recapitalization, extraordinary dividend or other significant corporate reorganization of the Company or any of its Subsidiaries, (iii) any action, proposal,

transaction or agreement that would delay, prevent, frustrate, impede or interfere with the Merger or the other Transactions or result in the failure of any condition set forth in ARTICLE VII of the Merger Agreement to be satisfied, and (iv) any action, proposal, transaction or agreement that would result in a breach of any covenant, representation or warranty or other obligation or agreement of the Company under the Merger Agreement or of the Voting Stockholder under this Agreement.

Section 5. Irrevocable Proxy. In furtherance of the agreements contained in Section 3 of this Agreement and subject to the last sentence of this Section 5, the Voting Stockholder hereby irrevocably grants to and appoints Parent and each of the executive officers of Parent, in their respective capacities as officers of Parent, as the case may be, and any individual who shall hereafter succeed to any such office of Parent, and each of them individually, the Voting Stockholder’s proxy and attorney-in-fact (with full power of substitution), for and in the name, place and stead of the Voting Stockholder, to vote all Subject Shares that are outstanding and beneficially owned by the Voting Stockholder from time to time, to grant or withhold a consent or approval in respect of the Subject Shares and to execute and deliver a proxy to vote the Subject Shares. The foregoing proxy shall be deemed to be a proxy coupled with an interest, is (subject to the last sentence of this Section 5) irrevocable (and as such shall survive and not be affected by the death, incapacity, mental illness or insanity of the Voting Stockholder) and shall not be terminated by operation of Law or upon the occurrence of any other event other than the termination of this Agreement pursuant to Section 12(d) hereof. The Voting Stockholder represents and warrants to Parent that all proxies heretofore given in respect of the Subject Shares are not irrevocable and that all such proxies have been properly revoked or are no longer in effect as of the date hereof. The Voting Stockholder hereby affirms that the irrevocable proxy set forth in this Section 5 is given by the Voting Stockholder in connection with, and in consideration of and as an inducement to, Parent entering into the Merger Agreement and that such irrevocable proxy is given to secure the obligations of the Voting Stockholder under Section 3 of this Agreement. Parent covenants and agrees with the Voting Stockholder that Parent will exercise the foregoing proxy consistent with the provisions of Section 3 of this Agreement. Notwithstanding the foregoing, this irrevocable proxy shall terminate automatically with respect to any Company Shares that the Voting Stockholder Transfers or with respect to which the Voting Stockholder enters into an agreement to Transfer, and upon any such event such Company Shares shall no longer be Subject Shares hereunder.

Section 8. Representations and Warranties of the Voting Stockholder. The Voting Stockholder represents and warrants to Parent as to himself or itself that:

the transactions contemplated hereby have been duly authorized by all necessary action on the part of the Voting Stockholder and no further proceedings or actions on the part of the Voting Stockholder are necessary to authorize the execution, delivery or performance of this Agreement or the consummation of the transactions contemplated hereby.

(d) Ownership of Shares. As of the date hereof, the Voting Stockholder is a beneficial owner of the number of Subject Shares set forth on Schedule A. As of the date hereof, such Subject Shares together constitute all of the Company Shares beneficially owned by the Voting Stockholder. The Voting Stockholder has, with respect to such Subject Shares, either (i) the sole power, directly or indirectly, to vote or dispose of the Subject Shares or (ii) the shared power, directly or indirectly, to vote or dispose of the Subject Shares together with (but only with) one or more other Company Stockholders subject to a voting agreement with Parent on terms substantially similar to the terms of this Agreement (such Stockholder, an “Other Voting Stockholder”), and as such, has the complete and exclusive power, individually or together with one or more Other Voting Stockholders, to, directly or indirectly, (x) issue (or cause the issuance of) instructions with respect to the matters set forth in Section 3 of this Agreement, (y) agree to all matters set forth in this Agreement and (z) demand and waive appraisal or dissent rights. As of the date hereof, except as set forth opposite the Voting Stockholder’s name on Schedule A, such Subject Shares are issued and outstanding and the Voting Stockholder does not beneficially own any warrants, Company Stock Options, Company RSUs or other rights to acquire any Company Shares. As of the date hereof, the Subject Shares are free and clear of Liens, proxies, powers of attorney, voting trusts, options, rights of first offer or refusal or agreements (other than any Liens or proxy created by this Agreement or Liens that would not prevent or impair the ability of the Voting Stockholder to perform its obligations hereunder). Except as provided in this Agreement, as of the date hereof, there are no agreements or arrangements of any kind, contingent or otherwise, to which the Voting Stockholder is a party obligating the Voting Stockholder to Transfer, or cause to be Transferred, any of the Subject Shares. Except pursuant to the Merger Agreement, as of the date hereof, no Person has any contractual or other right or obligation to purchase or otherwise acquire any of the Subject Shares.

properties or assets (including the Subject Shares) that could reasonably be expected to impair the ability of the Voting Stockholder to perform his or its obligations hereunder or to consummate the transactions contemplated hereby on a timely basis.

If to the Voting Stockholder, to his or its address set forth under the Voting Stockholder’s name on Schedule A, with copies to:

(c) Assignment; Binding Effect. Neither the Voting Stockholder, on the one hand, nor Parent, on the other hand, may assign this Agreement or any of his or its rights, interests or obligations hereunder (whether by operation of Law or otherwise) without the prior written approval of Parent or the Voting Stockholder, as applicable, and any attempted assignment without such prior written approval shall be void and without legal effect; provided, however, that Parent may assign its rights hereunder to a direct or indirect wholly-owned Subsidiary of Parent, it being understood and agreed that any such assignment shall not relieve Parent of its obligations hereunder. Subject to the preceding sentence, this Agreement shall be binding upon and inure to the benefit of the parties hereto and their respective permitted successors and permitted assigns.

to accept jurisdiction over a particular matter, any federal court within the State of Delaware). The parties hereby (A) submit to the exclusive jurisdiction of the Court of Chancery of the State of Delaware (or, only if the Court of Chancery of the State of Delaware declines to accept jurisdiction over a particular matter, any federal court within the State of Delaware) for the purpose of any Action arising out of or relating to this Agreement brought by any party and (B) irrevocably waive, and agree not to assert by way of motion, defense, or otherwise, in any such Action, any claim that it is not subject personally to the jurisdiction of the above-named courts, that its property is exempt or immune from attachment or execution, that the Action is brought in an inconvenient forum, that the venue of the Action is improper, or that this Agreement or the Transactions may not be enforced in or by any of the above-named courts. Each of the parties hereto agrees that mailing of process or other papers in connection with any action or proceeding in the manner provided in Section 12(a) or such other manner as may be permitted by Law shall be valid and sufficient service of process.

(h) Expenses. All costs and expenses incurred in connection with this Agreement shall be paid by or on behalf of the party incurring such cost or expense.

(i) Headings. The Section headings contained in this Agreement are inserted for convenience only and shall not affect in any way the meaning or interpretation of this Agreement.

(j) Interpretation. Any reference to any national, state, local or foreign Law shall be deemed also to refer to all rules and regulations promulgated thereunder, unless the context otherwise requires. When a reference is made in this Agreement to Sections or Schedules, such reference shall be to a Section of or Schedule to this Agreement unless otherwise indicated. Whenever the words “include,” “includes” or “including” are used in this Agreement, they shall be deemed to be followed by the words “without limitation.” In this Agreement, the Voting Stockholder of any Company Shares held in trust shall be deemed to be the relevant trust and/or the trustees thereof acting in their capacities as such trustees, in each case as the context may require to be most protective of Parent, including for purposes of such trustees’ representations and warranties as to the proper organization of the trust, their power and authority as trustees and the non-contravention of the trust’s governing instruments.

(l) Specific Performance. The Voting Stockholder agrees that irreparable damage may occur in the event any provision of this Agreement were not performed by him or it in accordance with the terms hereof and that money damages would not be a sufficient remedy for any breach of this Agreement, and accordingly, Parent shall be entitled to seek specific performance of the terms hereof, without any requirement to post bond, in addition to any other remedy at law or equity.

IN WITNESS WHEREOF, the parties hereto have caused this Agreement to be executed by their duly authorized respective officers as of the date first written above.

(a) Any stockholder of a corporation of this State who holds shares of stock on the date of the making of a demand pursuant to subsection (d) of this section with respect to such shares, who continuously holds such shares through the effective date of the merger or consolidation, who has otherwise complied with subsection (d) of this section and who has neither voted in favor of the merger or consolidation nor consented thereto in writing pursuant to § 228 of this title shall be entitled to an appraisal by the Court of Chancery of the fair value of the stockholder’s shares of stock under the circumstances described in subsections (b) and (c) of this section. As used in this section, the word “stockholder” means a holder of record of stock in a corporation; the words “stock” and “share” mean and include what is ordinarily meant by those words; and the words “depository receipt” mean a receipt or other instrument issued by a depository representing an interest in 1 or more shares, or fractions thereof, solely of stock of a corporation, which stock is deposited with the depository.

(b) Appraisal rights shall be available for the shares of any class or series of stock of a constituent corporation in a merger or consolidation to be effected pursuant to § 251 (other than a merger effected pursuant to § 251(g) of this title), § 252, § 254, § 255, § 256, § 257, § 258, § 263 or § 264 of this title:

(1) Provided, however, that no appraisal rights under this section shall be available for the shares of any class or series of stock, which stock, or depository receipts in respect thereof, at the record date fixed to determine the stockholders entitled to receive notice of the meeting of stockholders to act upon the agreement of merger or consolidation, were either (i) listed on a national securities exchange or (ii) held of record by more than 2,000 holders; and further provided that no appraisal rights shall be available for any shares of stock of the constituent corporation surviving a merger if the merger did not require for its approval the vote of the stockholders of the surviving corporation as provided in § 251(f) of this title.

(2) Notwithstanding paragraph (1) of this subsection, appraisal rights under this section shall be available for the shares of any class or series of stock of a constituent corporation if the holders thereof are required by the terms of an agreement of merger or consolidation pursuant to §§ 251, 252, 254, 255, 256, 257, 258, 263 and 264 of this title to accept for such stock anything except:

a. Shares of stock of the corporation surviving or resulting from such merger or consolidation, or depository receipts in respect thereof;

b. Shares of stock of any other corporation, or depository receipts in respect thereof, which shares of stock (or depository receipts in respect thereof) or depository receipts at the effective date of the merger or consolidation will be either listed on a national securities exchange or held of record by more than 2,000 holders;

c. Cash in lieu of fractional shares or fractional depository receipts described in the foregoing subparagraphs a. and b. of this paragraph; or

d. Any combination of the shares of stock, depository receipts and cash in lieu of fractional shares or fractional depository receipts described in the foregoing subparagraphs a., b. and c. of this paragraph.

(3) In the event all of the stock of a subsidiary Delaware corporation party to a merger effected under § 253 or § 267 of this title is not owned by the parent immediately prior to the merger, appraisal rights shall be available for the shares of the subsidiary Delaware corporation.

(c) Any corporation may provide in its certificate of incorporation that appraisal rights under this section shall be available for the shares of any class or series of its stock as a result of an amendment to its certificate of incorporation, any merger or consolidation in which the corporation is a constituent corporation or the sale of all or substantially all of the assets of the corporation. If the certificate of incorporation contains such a provision, the procedures of this section, including those set forth in subsections (d) and (e) of this section, shall apply as nearly as is practicable.

(1) If a proposed merger or consolidation for which appraisal rights are provided under this section is to be submitted for approval at a meeting of stockholders, the corporation, not less than 20 days prior to the meeting, shall notify each of its stockholders who was such on the record date for notice of such meeting (or such members who received notice in accordance with § 255(c) of this title) with respect to shares for which appraisal rights are available pursuant to subsection (b) or (c) of this section that appraisal rights are available for any or all of the shares of the constituent corporations, and shall include in such notice a copy of this section and, if 1 of the constituent corporations is a nonstock corporation, a copy of § 114 of this title. Each stockholder electing to demand the appraisal of such stockholder’s shares shall deliver to the corporation, before the taking of the vote on the merger or consolidation, a written demand for appraisal of such stockholder’s shares. Such demand will be sufficient if it reasonably informs the corporation of the identity of the stockholder and that the stockholder intends thereby to demand the appraisal of such stockholder’s shares. A proxy or vote against the merger or consolidation shall not constitute such a demand. A stockholder electing to take such action must do so by a separate written demand as herein provided. Within 10 days after the effective date of such merger or consolidation, the surviving or resulting corporation shall notify each stockholder of each constituent corporation who has complied with this subsection and has not voted in favor of or consented to the merger or consolidation of the date that the merger or consolidation has become effective; or

(2) If the merger or consolidation was approved pursuant to § 228, § 253, or § 267 of this title, then either a constituent corporation before the effective date of the merger or consolidation or the surviving or resulting corporation within 10 days thereafter shall notify each of the holders of any class or series of stock of such constituent corporation who are entitled to appraisal rights of the approval of the merger or consolidation and that appraisal rights are available for any or all shares of such class or series of stock of such constituent corporation, and shall include in such notice a copy of this section and, if 1 of the constituent corporations is a nonstock corporation, a copy of § 114 of this title. Such notice may, and, if given on or after the effective date of the merger or consolidation, shall, also notify such stockholders of the effective date of the merger or consolidation. Any stockholder entitled to appraisal rights may, within 20 days after the date of mailing of such notice, demand in writing from the surviving or resulting corporation the appraisal of such holder’s shares. Such demand will be sufficient if it reasonably informs the corporation of the identity of the stockholder and that the stockholder intends thereby to demand the appraisal of such holder’s shares. If such notice did not notify stockholders of the effective date of the merger or consolidation, either (i) each such constituent corporation shall send a second notice before the effective date of the merger or consolidation notifying each of the holders of any class or series of stock of such constituent corporation that are entitled to appraisal rights of the effective date of the merger or consolidation or (ii) the surviving or resulting corporation shall send such a second notice to all such holders on or within 10 days after such effective date; provided, however, that if such second notice is sent more than 20 days following the sending of the first notice, such second notice need only be sent to each stockholder who is entitled to appraisal rights and who has demanded appraisal of such holder’s shares in accordance with this subsection. An affidavit of the secretary or assistant secretary or of the transfer agent of the corporation that is required to give either notice that such notice has been given shall, in the absence of fraud, be prima facie evidence of the facts stated therein. For purposes of determining the stockholders entitled to receive either notice, each constituent corporation may fix, in advance, a record date that shall be not more than 10 days prior to the date the notice is given, provided, that if the notice is given on or after the effective date of the merger or consolidation, the record date shall be such effective date. If no record date is fixed and the notice is given prior to the effective date, the record date shall be the close of business on the day next proceeding the day on which the notice is given.

(e) Within 120 days after the effective date of the merger or consolidation, the surviving or resulting corporation or any stockholder who has complied with subsections (a) and (d) of this section hereof and who is otherwise entitled to appraisal rights, may commence an appraisal proceeding by filing a petition in the Court of Chancery demanding a determination of the value of the stock of all such stockholders.

Notwithstanding the foregoing, at any time within 60 days after the effective date of the merger or consolidation, any stockholder who has not commenced an appraisal proceeding or joined that proceeding as a named party shall have the right to withdraw such stockholder’s demand for appraisal and to accept the terms offered upon the merger or consolidation. Within 120 days after the effective date of the merger or consolidation, any stockholder who has complied with the requirements of subsections (a) and (d) of this section hereof, upon written request, shall be entitled to receive from the corporation surviving the merger or resulting from the consolidation a statement setting forth the aggregate number of shares not voted in favor of the merger or consolidation and with respect to which demands for appraisal have been received and the aggregate number of holders of such shares. Such written statement shall be mailed to the stockholder within 10 days after such stockholder’s written request for such a statement is received by the surviving or resulting corporation or within 10 days after expiration of the period for delivery of demands for appraisal under subsection (d) of this section hereof, whichever is later. Notwithstanding subsection (a) of this section, a person who is the beneficial owner of shares of such stock held either in a voting trust or by a nominee on behalf of such person may, in such person’s own name, file a petition or request from the corporation the statement described in this subsection.

(f) Upon the filing of any such petition by a stockholder, service of a copy thereof shall be made upon the surviving or resulting corporation, which shall within 20 days after such service file in the office of the Register in Chancery in which the petition was filed a duly verified list containing the names and addresses of all stockholders who have demanded payment for their shares and with whom agreements as to the value of their shares have not been reached by the surviving or resulting corporation. If the petition shall be filed by the surviving or resulting corporation, the petition shall be accompanied by such a duly verified list. The Register in Chancery, if so ordered by the Court, shall give notice of the time and place fixed for the hearing of such petition by registered or certified mail to the surviving or resulting corporation and to the stockholders shown on the list at the addresses therein stated. Such notice shall also be given by 1 or more publications at least 1 week before the day of the hearing, in a newspaper of general circulation published in the City of Wilmington, Delaware or such publication as the Court deems advisable. The forms of the notices by mail and by publication shall be approved by the Court, and the costs thereof shall be borne by the surviving or resulting corporation.

(g) At the hearing on such petition, the Court shall determine the stockholders who have complied with this section and who have become entitled to appraisal rights. The Court may require the stockholders who have demanded an appraisal for their shares and who hold stock represented by certificates to submit their certificates of stock to the Register in Chancery for notation thereon of the pendency of the appraisal proceedings; and if any stockholder fails to comply with such direction, the Court may dismiss the proceedings as to such stockholder.

(h) After the Court determines the stockholders entitled to an appraisal, the appraisal proceeding shall be conducted in accordance with the rules of the Court of Chancery, including any rules specifically governing appraisal proceedings. Through such proceeding the Court shall determine the fair value of the shares exclusive of any element of value arising from the accomplishment or expectation of the merger or consolidation, together with interest, if any, to be paid upon the amount determined to be the fair value. In determining such fair value, the Court shall take into account all relevant factors. Unless the Court in its discretion determines otherwise for good cause shown, interest from the effective date of the merger through the date of payment of the judgment shall be compounded quarterly and shall accrue at 5% over the Federal Reserve discount rate (including any surcharge) as established from time to time during the period between the effective date of the merger and the date of payment of the judgment. Upon application by the surviving or resulting corporation or by any stockholder entitled to participate in the appraisal proceeding, the Court may, in its discretion, proceed to trial upon the appraisal prior to the final determination of the stockholders entitled to an appraisal. Any stockholder whose name appears on the list filed by the surviving or resulting corporation pursuant to subsection (f) of this section and who has submitted such stockholder’s certificates of stock to the Register in Chancery, if such is required, may participate fully in all proceedings until it is finally determined that such stockholder is not entitled to appraisal rights under this section.

(i) The Court shall direct the payment of the fair value of the shares, together with interest, if any, by the surviving or resulting corporation to the stockholders entitled thereto. Payment shall be so made to each such stockholder, in the case of holders of uncertificated stock forthwith, and the case of holders of shares represented by certificates upon the surrender to the corporation of the certificates representing such stock. The Court’s decree may be enforced as other decrees in the Court of Chancery may be enforced, whether such surviving or resulting corporation be a corporation of this State or of any state.

(j) The costs of the proceeding may be determined by the Court and taxed upon the parties as the Court deems equitable in the circumstances. Upon application of a stockholder, the Court may order all or a portion of the expenses incurred by any stockholder in connection with the appraisal proceeding, including, without limitation, reasonable attorney’s fees and the fees and expenses of experts, to be charged pro-rata against the value of all the shares entitled to an appraisal.

(k) From and after the effective date of the merger or consolidation, no stockholder who has demanded appraisal rights as provided in subsection (d) of this section shall be entitled to vote such stock for any purpose or to receive payment of dividends or other distributions on the stock (except dividends or other distributions payable to stockholders of record at a date which is prior to the effective date of the merger or consolidation); provided, however, that if no petition for an appraisal shall be filed within the time provided in subsection (e) of this section, or if such stockholder shall deliver to the surviving or resulting corporation a written withdrawal of such stockholder’s demand for an appraisal and an acceptance of the merger or consolidation, either within 60 days after the effective date of the merger or consolidation as provided in subsection (e) of this section or thereafter with the written approval of the corporation, then the right of such stockholder to an appraisal shall cease. Notwithstanding the foregoing, no appraisal proceeding in the Court of Chancery shall be dismissed as to any stockholder without the approval of the Court, and such approval may be conditioned upon such terms as the Court deems just; provided, however that this provision shall not affect the right of any stockholder who has not commenced an appraisal proceeding or joined that proceeding as a named party to withdraw such stockholder’s demand for appraisal and to accept the terms offered upon the merger or consolidation within 60 days after the effective date of the merger or consolidation, as set forth in subsection (e) of this section.

(l) The shares of the surviving or resulting corporation to which the shares of such objecting stockholders would have been converted had they assented to the merger or consolidation shall have the status of authorized and unissued shares of the surviving or resulting corporation.
