You are cordially invited to attend a special meeting of shareholders of Kenexa Corporation (“Kenexa”) to be held on , , 2012, at , Eastern Time at .

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 August 25, 2012, by and among International Business Machines Corporation (“IBM”), Jasmine Acquisition Corp. (“Sub”), a wholly-owned subsidiary of IBM, and Kenexa, as such agreement may be amended from time to time. Pursuant to the merger agreement, Sub will merge with and into Kenexa and as a result, under Pennsylvania law, Kenexa will become a wholly-owned subsidiary of IBM. 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 “golden parachute” compensation that may be paid or become payable to Kenexa’s named executive officers in connection with the merger, including the agreements and understandings with Kenexa pursuant to which such compensation may be paid or become payable.

If the merger is completed, Kenexa shareholders will be entitled to receive $46.00 in cash, without interest and less any applicable withholding taxes, for each share of Kenexa common stock owned by them as of the date of the merger.

Our board of directors unanimously determined that the terms and conditions of the merger and the merger agreement are fair to our shareholders and advisable and in the best interests of Kenexa. 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 “golden parachute” compensation that may be paid or become payable to Kenexa’s named executive officers in connection with the merger, including the agreements and understandings with Kenexa pursuant to which such compensation may be paid or become payable.

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 votes cast by all Kenexa shareholders entitled to vote on the merger. Failure to vote and abstentions will have no effect on any of the proposals presented at the special meeting. Only shareholders who owned shares of Kenexa common stock at the close of business on , 2012, 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.

If you fail to submit a proxy, your shares will not be counted for purposes of determining whether a quorum is present at the special meeting. If you attend the special meeting and wish to vote in person, you may revoke your proxy and vote in person.

This proxy statement is dated , 2012 and is first being mailed to shareholders of Kenexa on or about , 2012.

Kenexa Corporation, a Pennsylvania corporation (“Kenexa”), will hold a special meeting of shareholders at , at , Eastern Time, on , , 2012, for the following purposes:

Only record holders of Kenexa common stock at the close of business on , 2012 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 Kenexa’s common stock you own. The affirmative vote of the holders of a majority of votes cast by all Kenexa shareholders entitled to vote at the special meeting is required to adopt the merger agreement and to approve the proposal to adjourn the special meeting and certain “golden parachute” compensation, provided that a quorum is present. In the event that a quorum is not present in person or represented by proxy at the special meeting, it is expected that the special meeting will be adjourned by the chairman of the meeting to solicit additional proxies.

Under the Pennsylvania Business Corporation Law of 1988, the holders of any class or series of shares of a corporation are not entitled to exercise dissenters’ rights if the shares of the corporation are listed on a national securities exchange. Since Kenexa common stock is currently listed on The New York Stock Exchange, which is a national securities exchange, the holders of our common stock will not have the right to exercise dissenters’ rights in connection with the merger. If the merger agreement is adopted and the merger is completed, holders of Kenexa common stock who voted against the adoption of the merger agreement will be treated the same as holders who voted for the adoption of the merger agreement and their shares will automatically be converted into the right to receive the merger consideration.

You are cordially invited to attend the special meeting in person. Whether or not you expect to attend the special meeting, please complete, date, sign and return the enclosed proxy, or vote over the telephone or the Internet as instructed in these materials, as promptly as possible in order to ensure your representation at the special meeting. A return envelope (which is postage 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 “golden parachute” compensation that may be paid or become payable to Kenexa’s named executive officers in connection with the merger, including the agreements and understandings with Kenexa pursuant to which such compensation may be paid or become payable. If you fail to return your proxy card and do not submit your proxy via the Internet or by telephone, your shares will not be counted for purposes of determining whether a quorum is present at the special meeting and will have no effect on (i) the merger proposal, (ii) the proposal to adjourn the special meeting to a later date, if necessary or appropriate, to permit solicitations of additional proxies or (iii) approval, on an advisory (non-binding) basis, of certain “golden parachute” compensation that may be paid or become payable to Kenexa’s named executive officers in connection with the merger, including the agreements and understandings with Kenexa pursuant to which such compensation may be paid or become payable, if 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 revoke your proxy in the manner described in the enclosed proxy statement at any time before it has been voted at the special meeting.

Our board of directors unanimously recommends that you vote “FOR” adoption of the merger agreement, “FOR” 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 “golden parachute” compensation that may be paid or become payable to Kenexa’s named executive officers in connection with the merger, including the agreements and understandings with Kenexa pursuant to which such compensation may be paid or become payable.

The merger is described in the accompanying proxy statement, which we urge you to read carefully. A copy of the merger agreement is attached as Annex A to the proxy statement.

Whether or not you expect to attend the special meeting, please complete, date, sign and return the enclosed proxy card, or vote over the telephone or the Internet as instructed in these materials, as promptly as possible in order to ensure your representation at the special meeting. A return envelope (which is postage 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.

The following Q&A is intended to address some commonly asked questions regarding the special meeting of shareholders and the merger. These questions and answers may not address all questions that may be important to you as a Kenexa shareholder. We urge you to read carefully the more detailed information contained elsewhere in this proxy statement, the annexes to this proxy statement and the documents we refer to in this proxy statement.

Except as otherwise specifically noted in this proxy statement, “we,” “our,” “us” and similar words in this proxy statement refer to Kenexa Corporation. In addition, throughout this proxy statement, we refer to Kenexa Corporation as “Kenexa,” to Jasmine Acquisition Corp. as “Sub” and to International Business Machines Corporation as “IBM.”

A: Our board of directors is furnishing this proxy statement in connection with the solicitation of proxies to be voted at a special meeting of our shareholders, or at any adjournments or postponements of the special meeting, at which our shareholders will be asked to vote to adopt the merger agreement and approve certain proposals that we describe herein.

A: The special meeting of our shareholders will be held on , , 2012 at , Eastern Time, at .

A: You are being asked to grant to the proxies identified in the enclosed proxy card authority to vote to adopt a merger agreement that provides for the acquisition of Kenexa by IBM. The proposed acquisition would be accomplished through a merger of Sub, a wholly-owned subsidiary of IBM, with and into Kenexa. As a result of the merger, we will become a wholly-owned subsidiary of IBM and will no longer be a publicly-traded company. Our common stock will cease to be listed on The New York Stock Exchange, which we refer to in this proxy statement as the NYSE, and will be deregistered under the Securities Exchange Act of 1934, as amended, which we refer to in this proxy statement as the Securities Exchange Act.

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 shareholders 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 “golden parachute” compensation that may be paid or become payable to Kenexa’s named executive officers in connection with the merger, including the agreements and understandings with Kenexa pursuant to which such compensation may be paid or become payable.

A: At a meeting held on August 25, 2012, our board of directors unanimously approved the merger, the merger agreement and the other transactions contemplated thereby, and determined that the terms and conditions of the merger and the merger agreement are fair to our shareholders and advisable and in the best interests of Kenexa. Our board of directors unanimously recommends that you vote “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 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 “golden parachute” compensation that may be paid or become payable to Kenexa’s named executive officers in connection with the merger, including the agreements and understandings with Kenexa pursuant to which such compensation may be paid or become payable.

A: As a result of the merger, our shareholders will be entitled to receive $46.00 in cash, without interest and less any applicable withholding taxes, for each share of our common stock they own as of the date of the completion of the merger. For example, if you own 100 shares of our common stock, you will be entitled to receive $4,600.00 in cash, without interest, less any applicable withholding taxes, in exchange for your 100 shares upon the completion of the merger. You will not own shares in the surviving corporation.

A: The merger is subject to compliance with the applicable requirements of the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended, or the HSR Act, and clearance under the antitrust laws of various foreign jurisdictions. See “The Merger—Regulatory Matters” beginning on page 45.

A: We are working toward completing the merger as quickly as possible and currently expect to consummate the merger in the fourth quarter of calendar year 2012. In addition to obtaining shareholder approval, we must satisfy all other closing conditions, including the receipt of regulatory approvals.

A: Under Section 1571 of the Pennsylvania Business Corporation Law of 1988, the holders of any class or series of shares of a corporation are not entitled to exercise dissenters’ rights in connection with a merger if the shares of the corporation are listed on a national securities exchange. Consequently, because our common stock is currently listed on the NYSE, which is a national securities exchange, the holders of our common stock will not have the right to exercise dissenters’ rights in connection with the merger.

If the merger agreement is adopted and the merger is completed, holders of Kenexa common stock who voted against the adoption of the merger agreement will be treated the same as holders who voted for the adoption of the merger agreement and their shares will automatically be converted into the right to receive the merger consideration.

Q: What will happen to outstanding Kenexa equity compensation awards in the merger?

A: Subject to any provisions to the contrary in an offer letter between an individual employee of Kenexa and IBM (which we refer to as an Offer Letter), at the effective time of the merger:

A: The receipt of cash in exchange for Kenexa common stock converted pursuant to the merger will be a taxable transaction for U.S. federal income tax purposes and may also be a taxable transaction under applicable state, local or foreign income or other tax laws. Generally, for U.S. federal income tax purposes, a U.S. shareholder will recognize gain or loss equal to the difference between the amount of cash received by the shareholder in exchange for Kenexa common stock converted pursuant to the merger and the shareholder’s adjusted tax basis in the shares converted. If you are a non-U.S. holder, the merger will generally not be a taxable transaction to you under U.S. federal income tax laws unless you have certain connections to the United States, but may be a taxable transaction to you under non-U.S. federal income tax laws, and you are encouraged to seek tax advice regarding such matters. Because individual circumstances may differ, we recommend that you consult your own tax advisor to determine the particular tax effects to you. See “The Merger—Material United States Federal Income Tax Consequences of the Merger” beginning on page 43.

A: Only shareholders of record as of the close of business on , 2012 are entitled to receive notice of the special meeting and to vote the shares of our common stock that they held at that time at the special meeting or at any adjournments or postponements of the special meeting.

A: Adoption of the merger agreement requires the affirmative vote of the holders of a majority of votes cast by all Kenexa shareholders entitled to vote at the special meeting, provided that a quorum is present. In the event that a quorum is not present in person or represented by proxy at the special meeting, it is expected that the special meeting will be adjourned by the chairman of the meeting to solicit additional proxies.

As of , 2012, the record date for determining who is entitled to vote at the special meeting, there were shares of our common stock issued and outstanding. At the close of business on the record date, our directors and executive officers beneficially owned and were entitled to vote shares of our common stock, which represented approximately 7.7% of the shares of our outstanding common stock on that date. Each of our directors and executive officers have executed and delivered to IBM a shareholder agreement pursuant to which, among other things, each director and executive officer has agreed to vote their shares of common stock in favor of adoption of the merger agreement.

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.

Q: What vote is required to adjourn the special meeting to a later date, if necessary or appropriate, in order to solicit additional proxies from our shareholders in the event there are not sufficient votes in favor of adoption of the merger agreement at the time of the special meeting?

A: Approval of the proposal to adjourn the special meeting to a later date, if necessary or appropriate, in order to solicit additional proxies from our shareholders in the event there are not sufficient votes in favor of adoption of the merger agreement at the time of the special meeting requires the affirmative vote of the holders of a majority of votes cast by all Kenexa shareholders entitled to vote at the special meeting, provided that a quorum is present. In the event that a quorum is not present in person or represented by proxy at the special meeting, it is expected that the special meeting will be adjourned by the chairman of the meeting to solicit additional proxies.

Q: What vote is required to approve the non-binding proposal regarding the “golden parachute” compensation that the named executive officers of Kenexa will or may receive in connection with the merger?

A: Approval of the non-binding proposal regarding the “golden parachute” compensation that the named executive officers of Kenexa will or may receive in connection with the merger requires the affirmative vote of the holders of a majority of votes cast by all Kenexa shareholders entitled to vote at the special meeting, provided that a quorum is present. In the event that a quorum is not present in person or represented by proxy at the special meeting, it is expected that the special meeting will be adjourned by the chairman of the meeting to solicit additional proxies.

Q: Why am I being asked to cast a non-binding, advisory vote to approve the “golden parachute” compensation that the named executive officers of Kenexa will or may receive in connection with the merger?

A: Section 14A of the Securities Exchange Act requires us to conduct an advisory (non-binding) vote with respect to certain “golden parachute” compensation that may be paid or become payable to Kenexa’s named executive officers in connection with the merger, including the agreements and understandings with Kenexa pursuant to which such compensation may be paid or become payable.

Q: What will happen if our shareholders do not approve the “golden parachute” compensation at the special meeting?

A: Approval of the “golden parachute” compensation that may be paid or become payable to Kenexa’s named executive officers in connection with the merger, including the agreements and understandings with Kenexa pursuant to which such compensation may be paid or become payable, is a vote separate and apart from the vote to adopt the merger agreement and is not a condition to completion of the merger. The vote with respect to the “golden parachute” compensation is an advisory vote and will not be binding on Kenexa or IBM. Therefore, if the merger is approved by our shareholders and completed, the “golden parachute” compensation will be paid to the named executive officers if and when due, regardless of the outcome of the advisory vote on “golden parachute” compensation.

Q: If my broker holds my shares in “street name,” will my broker vote my shares for me?

A: No. Your broker will not be able to vote your shares without instructions from you. You should instruct your broker to vote your shares following the procedure provided by your broker. Without instructions, your shares will not be voted, which will have no effect on (i) the merger proposal, (ii) the proposal to adjourn the special meeting to a later date, if necessary or appropriate, to permit solicitations of additional proxies or (iii) the proposal to approve, on an advisory (non-binding) basis, of certain “golden parachute” compensation that may be paid or become payable to Kenexa’s named executive officers in connection with the merger, including the agreements and understandings with Kenexa pursuant to which such compensation may be paid or become payable.

A: We urge you to read this proxy statement carefully and consider how the merger affects you. Then mail your completed, dated and signed proxy card in the enclosed return envelope as soon as possible, or submit a proxy via the Internet or telephone, so that your shares can be voted at the special meeting of our shareholders. If you hold your shares of our common stock in “street name,” follow the instructions you receive from your broker or bank. Please do not send your stock certificates with your proxy card.

A: Yes. If your shares are registered in your name, you may attend the special meeting and vote your shares in person, rather than signing and returning your proxy card or submitting a proxy via the Internet or telephone. If your shares are held in “street name,” you must obtain a proxy from your broker or other nominee in order to attend the special meeting and vote in person. Even if you plan to attend the special meeting in person, we urge you to complete, sign, date and return the enclosed proxy card or submit a proxy via the Internet or telephone to ensure that your shares will be represented at the special meeting.

Q: How do I vote my shares of common stock? May I submit a proxy via the Internet or telephone?

A: If your shares are registered in your name, you may cause your shares to be voted by returning a signed proxy card or voting in person at the special meeting. Additionally, you may submit a proxy authorizing the voting of

your shares via the Internet at or telephonically by calling . You must have the enclosed proxy card available and follow the instructions on the proxy card in order to submit a proxy via the Internet or telephone.

Q: What happens if I do not return my proxy card, submit a proxy via the Internet or telephone or attend the special meeting and vote in person?

A: In the event that a quorum is not present in person or represented by proxy at the special meeting, it is expected that the special meeting will be adjourned by the chairman of the meeting to solicit additional proxies. If a quorum is present in person or represented by proxy at the special meeting, approval of (i) adoption of the merger agreement, (ii) 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) the proposal regarding “golden parachute” compensation, require the affirmative vote of the holders of a majority of votes cast by all Kenexa shareholders entitled to vote at the special meeting and, therefore, if you do not vote in person or by proxy, it will have no effect on the outcome of such proposals.

Q: May I change my vote after I have mailed my signed proxy card or delivered a proxy via the Internet or telephone?

A: Yes. You may change your vote at any time before your proxy card is voted at the special meeting. If you have sent a proxy directly to Kenexa, you may revoke your proxy by:

If you have instructed a broker or other nominee to vote your shares, you may revoke your proxy only by following the directions received from your broker or nominee to change those instructions.

Revocation of a proxy will not affect any vote taken prior to revocation. Attendance at the special meeting will not in itself constitute the revocation of a proxy; you must vote in person at the special meeting to revoke a previously delivered proxy.

A: You may receive more than one set of voting materials, including multiple copies of this proxy statement and multiple proxy cards or voting instruction cards. For example, if you hold your shares in more than one brokerage account, you will receive a separate voting instruction card for each brokerage account in which you hold shares. If you are a shareholder of record and your shares are registered in more than one name, you will

receive more than one proxy card. Please complete, sign, date and return (or submit via the Internet or telephone with respect to) each proxy card and voting instruction card that you receive.

Q: What happens if I sell or otherwise transfer my shares of Kenexa common stock before the special meeting?

A: The record date for the special meeting is earlier than the date of the special meeting and the date that the merger is expected to be completed. If you sell or otherwise transfer your shares of our common stock after the record date but before the special meeting, you will retain your right to vote at the special meeting but will transfer the right to receive the merger consideration. Even if you sell or otherwise transfer your shares of our common stock after the record date, we urge you to complete, sign, date and return the enclosed proxy or submit your proxy via the Internet or telephone.

A: No. After the merger is completed, you will receive written instructions for exchanging your shares of our common stock for the merger consideration of $46.00 in cash, without interest and less any applicable withholding taxes, for each share of our common stock you hold.

A: If you would like additional copies, without charge, of this proxy statement or if you have questions about the merger, including the procedures for voting your shares, you should contact:

Neither the Securities and Exchange Commission, which we may refer to in this Proxy Statement as the SEC, nor any state securities regulatory agency has approved or disapproved the merger, passed upon the merits or fairness of the merger or passed upon the adequacy or accuracy of the disclosures in this proxy statement. Any representation to the contrary is a criminal offense.

The forward-looking statements are subject to various risks and uncertainties that could cause actual results to differ materially from those described in the forward-looking statements. Generally, these forward-looking statements can be identified by the use of forward-looking terminology such as “anticipate,” “believe,” “estimate,” “expect,” “forecast,” “intend,” “plan,” “project,” “should,” “could” and similar expressions. Factors that may affect those forward-looking statements include, among other things:

We caution you that reliance on any forward-looking statement involves risks and uncertainties and that, although we believe that the assumptions on which our forward-looking statements are based are reasonable, any of those assumptions could prove to be inaccurate, and as a result, the forward-looking statements based on those assumptions could be incorrect. In light of these and other uncertainties, you should not conclude that we will necessarily achieve any plans and objectives or projected financial results referred to in any of the forward-looking statements. We do not undertake to release the results of any revisions of these forward-looking statements to reflect future events or circumstances.

Sub, a Pennsylvania corporation and a wholly-owned subsidiary of IBM, 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. Sub has not conducted any business operations other than in connection with the transactions contemplated by the merger agreement. Upon consummation of the merger, Sub will cease to exist, and Kenexa will continue as the surviving corporation.

Treatment of Stock Options, Restricted Stock Units, Restricted Stock and Purchase Rights (page 48)

Cash-Out Options. Subject to any provisions to the contrary in an Offer Letter, each outstanding and unexercised option to acquire shares of our common stock to the extent that such option either (i) is vested (or will vest in connection with the merger), (ii) is held by any of our or our subsidiaries’ non-employee directors, consultants or independent contractors or (iii) has an exercise price per share greater than or equal to the merger consideration of $46.00 per share will be cancelled at the effective time of the merger and will be converted into the right of the holder thereof to receive, in consideration for such cancellation, an amount in cash, without interest and less any applicable withholding taxes, payable at or as soon as practicable following the effective time of the merger, equal to the product of the number of shares of our common stock that are subject to such option, and the excess, if any, of the merger consideration of $46.00 per share over the exercise price per share of the common stock subject to such option.

Rollover Options. Subject to any provisions to the contrary in an Offer Letter, each outstanding and unexercised option to acquire shares of our common stock that will not be cancelled in the manner described in the preceding paragraph will be converted into an option to acquire, on substantially the same terms and conditions as were applicable to such option prior to the effective time of the merger, the number of shares of IBM’s common stock equal to the product of the number of shares of our common stock that are subject to such option and the exchange ratio (which will be determined in accordance with the merger agreement) rounded down to the nearest whole share of IBM’s common stock. The exercise price of such converted option per share of IBM’s common stock as of immediately following such conversion will be equal to the per share exercise price for the shares of our common stock purchasable pursuant to such option prior to the effective time of the merger divided by the exchange ratio, rounded up to the nearest whole cent.

Cash-Out Restricted Stock Units. Subject to any provisions such restricted stock unit to the contrary in an Offer Letter, each outstanding and unsettled restricted stock unit to the extent that such restricted stock unit either (i) is vested (or will vest in connection with the merger) or (ii) is held by any of our or our subsidiaries’ non-employee directors, consultants or independent contractors will be cancelled at the effective time of the merger and will be converted into the right of the holder thereof to receive in consideration for such cancellation an amount in cash, without interest and less any applicable withholding taxes, payable at or as soon as practicable following the effective time of the merger, equal to the product of the number of shares of our common stock that are subject to such restricted stock unit and the merger consideration of $46.00 per share.

a number of shares of IBM’s common stock equal to the product of the number of shares of our common stock underlying the restricted stock unit prior to the effective time of the merger and the exchange ratio (which will be determined in accordance with the merger agreement) rounded down to the nearest whole share of IBM’s common stock.

Each outstanding share of restricted stock will be converted into the right to receive the merger consideration of $46.00 per share.

Under the merger agreement, the 2006 Employee Stock Purchase Plan, which we refer to in this proxy statement as the ESPP, will be terminated no later than the last trading day prior to the effective time of the merger, and, if the ESPP remains in effect on the last trading day prior to the effective time of the merger, the amounts credited to the accounts of participants in the ESPP will be distributed to such participants as soon as practicable after the closing of the merger.

Our common stock is listed on the NYSE under the symbol “KNXA.” On August 24, 2012, the last trading day before the public announcement of the merger, the closing price for our common stock was $32.39 per share, and on , 2012, the latest practicable trading day before the printing of this proxy statement, the closing price for our common stock was $ per share.

We did not declare or pay any cash dividends on our common stock during the three most recent fiscal years.

Material United States Federal Income Tax Consequences of the Merger (page 43)

The conversion of shares of our common stock into the right to receive $46.00 per share of cash merger consideration generally will be a taxable transaction to our shareholders for U.S. federal income tax purposes. See “The Merger—Material United States Federal Income Tax Consequences of the Merger” beginning on page 43.

Tax matters can be complicated, and the tax consequences of the merger to you will depend on the facts of your own situation. We strongly recommend that you consult your own tax advisor to fully understand the tax consequences of the merger to you.

Recommendation of Kenexa’s Board of Directors and Reasons for the Merger (page 22)

Our board of directors unanimously recommends that you vote “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 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 “golden parachute” compensation that may be paid or become payable to Kenexa’s named executive officers in connection with the merger, including the agreements and understandings with Kenexa pursuant to which such compensation may be paid or become payable. At a meeting of our board of directors on August 25, 2012, after consultation with our financial and legal advisors, our board of directors unanimously determined that the terms and conditions of the merger and the merger agreement are fair to our shareholders and advisable and in the best interests of Kenexa and unanimously approved the merger, the merger agreement and the other transactions contemplated thereby.

In the course of reaching its decision, our board of directors consulted with our senior management, financial advisor and legal counsel, reviewed a significant amount of information and considered a number of factors. For a discussion of the factors considered by our board of directors in reaching its decision to approve the merger agreement and recommend that our shareholders adopt the merger agreement, see “The Merger—Recommendation of Kenexa’s Board of Directors and Reasons for the Merger” beginning on page 22.

In connection with the merger, on August 25, 2012, our financial advisor, Lazard Frères & Co. LLC, which we refer to as Lazard, rendered its oral opinion to our board of directors, subsequently confirmed in writing, that, as of such date, and based upon and subject to the assumptions, procedures, factors, qualifications and limitations, set forth therein, the per share merger consideration to be paid to holders of our common stock other than shares of our common stock held by IBM or Sub (such holders, collectively referred to this proxy statement as excluded holders), in the merger was fair, from a financial point of view, to such holders.

The full text of Lazard’s written opinion, dated August 25, 2012, which sets forth the assumptions made, procedures followed, factors considered, and qualifications and limitations on the review undertaken by Lazard in connection with its opinion is attached to this proxy statement as Annex B and is incorporated into this proxy statement by reference. We encourage you to read Lazard’s opinion, and the section entitled “The Merger—Opinion of Lazard Frères & Co. LLC” beginning on page 25 of this proxy statement, carefully and in their entirety. Lazard’s opinion was directed to our board of directors for the information and assistance of our board of directors in connection with its evaluation of the merger and only addressed the fairness, from a financial point of view, to the holders of our common stock (other than the excluded holders) of the per share merger consideration to be paid to such holders in the merger as of the date of Lazard’s opinion. Lazard’s opinion did not address any other aspect of the merger and was not intended to and does not constitute a recommendation to any holder of our common stock as to how such holder should vote or act with respect to the merger or any matter relating thereto.

Date, Time and Place. A special meeting of our shareholders will be held on , , 2012, at , at , Eastern Time, to consider and vote upon:

Record Date and Voting Power. You are entitled to vote at the special meeting if you owned shares of our common stock at the close of business on , 2012, the record date for the special meeting. You will have one vote at the special meeting for each share of our common stock you owned at the close of business on the record date. There are shares of our common stock outstanding and entitled to be voted at the special meeting.

Quorum. A quorum of shareholders is necessary to hold a valid special meeting. Under our bylaws, 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.

Required Vote. The adoption of the merger agreement and the approval of (i) 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 and (ii) the proposal to approve, on an advisory (non-binding) basis, of certain “golden parachute” compensation that may be paid or become payable to our named executive officers in connection with the merger, including the agreements and understandings with us pursuant to which such compensation may be paid or become payable, require the affirmative vote of the holders of a majority of votes cast by all Kenexa shareholders entitled to vote at the special meeting, provided that a quorum is present. In the event that a quorum is not present in person or represented by proxy at the special meeting, it is expected that the special meeting will be adjourned by the chairman of the meeting to solicit additional proxies.

Interests of Kenexa’s Executive Officers and Directors in the Merger (page 33)

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 our shareholders generally, as described below. These interests may be different from, or in conflict with, your interests as one of our shareholders. The members of our board of directors were aware of these additional interests, and considered them, when they approved the merger agreement.

Pursuant to the terms of the merger agreement and agreements evidencing equity awards awarded to our non-employee directors, all of the then-unvested options and restricted stock held by each of our non-employee directors will become fully vested at the effective time of the merger. The general treatment of options and restricted stock in the merger, including such awards held by our non-employee directors, is described below under “The Merger—Treatment of Outstanding Stock Options” and “The Merger—Treatment of Outstanding Restricted Stock” beginning on pages 42 and 43, respectively.

Under the Kenexa Change in Control Severance Plan, which we may refer to in this Proxy Statement as the Change in Control Plan, all unvested equity and equity based awards held by our named executive officers will accelerate and become fully vested immediately prior to (and contingent on) the occurrence of a “change in control” (as such term is defined in the Change in Control Plan). The closing of the merger will meet the definition of a “change in control” under the Change in Control Plan.

Options and restricted stock units held by each of Messrs. Nooruddin (Rudy) S. Karsan and Troy A. Kanter will be afforded the treatment described in “The Merger—Treatment of Outstanding Stock Options” beginning on page 42 and “The Merger—Treatment of Outstanding Restricted Stock Units” beginning on page 42.

Each of Messrs. Donald F. Volk, James P. Restivo and Archie L. Jones, Jr. has received and accepted an Offer Letter. Messrs. Volk and Jones will continue to be entitled to the equity acceleration each is entitled to under the Change in Control Plan; however, their Offer Letters will supersede and replace their existing severance entitlements under the Change in Control Plan. Mr. Restivo’s Offer Letter will supersede and replace his existing Kenexa employment arrangement, and he will not be entitled to any of the benefits under such existing arrangements, including any severance or acceleration of vesting of equity based awards under the Change in Control Plan, except as provided under his Offer Letter. All of the Offer Letters are conditioned upon the closing of the merger and the executive officer’s continued employment with Kenexa through the closing of the merger and will provide certain retention/severance payments and equity compensation benefits to such individuals, as described below. In addition, each of Messrs. Karsan, Kanter, Volk, Restivo and Jones has entered into a non-competition and non-solicitation agreement with IBM.

Messrs. Karsan’s and Kanter’s employment arrangements with Kenexa will remain in effect following the merger. Pursuant to the Change in Control Plan, Messrs. Karsan and Kanter are each eligible to receive (A) a lump-sum payment equal to 1.75 times the sum of (i) his base salary and (ii) his target bonus opportunity for the fiscal year in which the termination occurs and (B) a payment of a pro-rata bonus for the year in which the termination occurs, determined and paid at the same time as other employee bonuses are paid with respect to such year, in the event that his employment is terminated without “cause” or he resigns for “good reason” (as such terms are defined in the Change in Control Plan) within two years after a change in control of Kenexa, subject to his execution of a release of claims.

The surviving corporation in the merger will assume, and IBM will cause the surviving corporation and its successors and assigns to comply with and honor, all rights to indemnification, advancement of expenses and exculpation from liabilities for acts or omissions occurring at or prior to the effective time of the merger existing in favor of our and our subsidiaries’ current or former directors or officers as provided in our and their respective certificates of incorporation or bylaws (or comparable organizational documents) and any indemnification or other agreements as in effect on the date of the merger agreement.

In the event the surviving corporation consolidates with or merges into another entity and is not the continuing or surviving entity of such consolidation or merger or transfers all or substantially all of its properties and assets to another entity, or if IBM dissolves the surviving corporation, IBM will cause the successors and assigns of the surviving corporation to comply with and honor the indemnification and other obligations set forth above.

At the close of business on the record date, our directors and executive officers beneficially owned and were entitled to vote shares of our common stock, which represented approximately 7.7% of the shares of our outstanding common stock on that date. Each of our directors and executive officers have executed and delivered to IBM a shareholder agreement pursuant to which, among other things, each director and executive officer has agreed to vote their shares of common stock in favor of adoption of the merger agreement and grant IBM an irrevocable proxy in respect thereof. Each of the shareholder agreements is substantially similar to the form of shareholder agreement attached as Exhibit A to the merger agreement.

Our, IBM’s and Sub’s obligations to effect the merger are subject to the satisfaction or waiver of the following conditions:

IBM’s and Sub’s obligations to effect the merger are further subject to the satisfaction by us or waiver by them of the following conditions:

Our obligations to effect the merger are subject to the further satisfaction by IBM and/or Sub or waiver by us of the following conditions:

We have agreed that we will not, and will not authorize or permit any of our subsidiaries to, nor will we authorize or permit any of our or our subsidiaries’ directors, officers or employees or any of our or their investment bankers, attorneys, accountants or other advisors or representatives to, directly or indirectly:

Despite these general prohibitions, at any time prior to the adoption of the merger agreement by our shareholders and subject to the conditions described below under the heading “The Merger Agreement—Covenants—No Solicitation of Acquisition Proposals” beginning on page 56, in response to a bona fide written unsolicited takeover proposal that our board determines in good faith is, 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—Covenants—Board Recommendation” beginning on page 57) and which did not result from our breach of the merger agreement, we may and may permit and authorize our subsidiaries and our and our subsidiaries’ representatives to:

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

We will be required to pay a termination fee of $52 million and reimburse IBM for its expenses up to $5 million if:

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 filed 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 September 10 and September 11, 2012 and on September 18, 2012, we were informed that early termination of the waiting period was granted. The merger is also subject to review

by the governmental authorities of various other jurisdictions under the antitrust or competition laws of those jurisdictions. We will file the appropriate notifications in each such jurisdiction and are pursuing the approval of the transaction.

Under Section 1571 of the Pennsylvania Business Corporation Law of 1988, the holders of any class or series of shares of a corporation are not entitled to exercise dissenters’ rights if the shares of the corporation are listed on a national securities exchange. Consequently, because our common stock is currently listed on the NYSE, which is a national securities exchange, the holders of our common stock will not have the right to exercise dissenters’ rights in connection with the merger.

Our common stock is listed on the NYSE under the symbol “KNXA.” This table shows, for the periods indicated, the range of intraday high and low per share sales prices for our common stock as reported on the NYSE.

The following table sets forth the closing price per share of our common stock, as reported on the NYSE on August 24, 2012, the last 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 NYSE and deregistered under the Securities Exchange Act.

We did not declare or pay any cash dividends on our common stock during the three most recent fiscal years.

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

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 “golden parachute” compensation that may be paid or become payable to our named executive officers in connection with the merger, including the agreements and understandings with us pursuant to which such compensation may be paid or become payable.

Only holders of record of our common stock at the close of business on , 2012, 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 on the proposal to adopt the merger agreement, the proposal to adjourn the special meeting to a later date, if necessary or appropriate, to solicit additional proxies and the proposal to approve, on an advisory (non-binding) basis, of certain “golden parachute” compensation that may be paid or become payable to Kenexa’s named executive officers in connection with the merger, including the agreements and understandings with Kenexa pursuant to which such compensation may be paid or become payable.

A quorum of shareholders 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 by the chairman of the meeting to 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 and approval of (i) the proposal to adjourn the special meeting to a later date, if necessary or appropriate, in order to solicit additional proxies from our shareholders and (ii) the proposal to approve, on an advisory (non-binding) basis, of certain “golden parachute” compensation that may be paid or become payable to our named executive officers in connection with the merger, including the agreements and understandings with us pursuant to which such compensation may be paid or become payable, require the affirmative vote of the holders of a majority of votes cast by all Kenexa shareholders entitled to vote at the special meeting, provided that a quorum is present. Adoption of the merger agreement is a condition to the closing of the merger.

to IBM a shareholder agreement pursuant to which, among other things, each director and executive officer has agreed to vote their shares of common stock “FOR” adoption of the merger agreement. 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 “golden parachute” compensation that may be paid or become payable to Kenexa’s named executive officers in connection with the merger, including the agreements and understandings with Kenexa pursuant to which such compensation may be paid or become payable.

If your shares are registered in your name, you may cause your shares to be voted at the special meeting by returning a signed proxy card or voting in person at the meeting. Additionally, you may submit a proxy authorizing the voting of your shares via the Internet at or by telephone by calling . You must have the enclosed proxy card available, and follow the instructions on the proxy card, in order to submit a proxy via the Internet or telephone.

If your shares are registered in your name and you plan to attend the special meeting and wish to vote in person, you will be given a ballot at the meeting. If your shares are registered in your name, you are encouraged to submit a proxy card even if you plan to attend the special meeting in person.

Voting instructions are included on your proxy card. 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 shareholder. 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 “golden parachute” compensation that may be paid or become payable to our named executive officers in connection with the merger, including the agreements and understandings with us pursuant to which such compensation may be paid or become payable, 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 “golden parachute” payments unless it is specifically marked “FOR” the adjournment proposal and/or “FOR” the proposal regarding “golden parachute” payments.

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 by telephone through your broker or nominee, if such a service is provided. To provide voting instructions via the Internet or telephone, you should follow the instructions on the voting form provided by your broker or nominee. If you plan to attend the special meeting, you will need a proxy from your broker or nominee in order to be given a ballot to vote the shares. If you do not return your broker’s or nominee’s voting form, provide voting instructions via the Internet or telephone through your broker or nominee, if possible, or attend the special meeting and vote in person with a proxy from your broker or nominee, it will have no effect on the (i) the merger proposal, (ii) the proposal to adjourn the special meeting to a later date, if necessary or appropriate, to permit solicitations of additional proxies or (iii) the proposal to approve, on an advisory (non-binding) basis, of certain “golden parachute” compensation that may be paid or become payable to our named executive officers in connection with the merger, including the agreements and understandings with us pursuant to which such compensation may be paid or become payable.

Any proxy you give pursuant to this solicitation may be revoked by you at any time before it is voted. Proxies may be revoked as follows:

If you have instructed a broker or nominee to vote your shares, you may revoke your proxy only by following the directions received from your broker or nominee to change those instructions.

Our board of directors has unanimously approved the merger, the merger agreement and the other transactions contemplated thereby, and determined that the terms and conditions of the merger agreement and the merger are fair to our shareholders and advisable and in the best interests of Kenexa. Our board of directors unanimously recommends that our shareholders (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 “golden parachute” compensation that may be paid or become payable to our named executive officers in connection with the merger, including the agreements and understandings with us pursuant to which such compensation may be paid or become payable.

Shareholders 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 no effect on the approval of (i) the merger proposal, (ii) 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) the proposal to approve, on an advisory (non-binding) basis, of certain “golden parachute” compensation that may be paid or become payable to our named executive officers in connection with the merger, including the agreements and understandings with us pursuant to which such compensation may be paid or become payable, provided that a quorum is present.

The expense of soliciting proxies in the enclosed form will be borne by us. We have retained Georgeson Inc., a proxy solicitation firm, to solicit proxies in connection with the special meeting at a cost of approximately $8,500 plus expenses. We may reimburse brokers, banks and other custodians, nominees and fiduciaries representing beneficial owners of shares for their expenses in forwarding soliciting materials to such beneficial owners. Proxies may be solicited by certain of our directors, officers and employees, personally or by telephone, facsimile or other means of communication. No additional compensation will be paid for such services.

A list of our shareholders entitled to vote at the special meeting will be available for examination by any of our shareholders at the special meeting. For 10 days prior to the special meeting, this shareholder list will be available for inspection by any shareholder for any purpose germane to the special meeting during ordinary business hours at our corporate offices located at Kenexa Corporation, 650 East Swedesford Road, Second Floor, Wayne, Pennsylvania 19087.

Our principal executive offices are located at 650 East Swedesford Road, Second Floor, Wayne, Pennsylvania 19087. Kenexa’s website is located at http://www.kenexa.com. Additional information regarding Kenexa is contained in our filings with the SEC. See “Where You Can Find More Information” beginning on page 73.

IBM’s principal executive offices are located at New Orchard Road, Armonk, New York 10504 and its telephone number is (914) 499-1900. Additional information regarding IBM is contained in IBM’s filings with the SEC. See “Where You Can Find More Information” beginning on page 73.

Sub, a Pennsylvania corporation and wholly-owned subsidiary of IBM, 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. Sub’s principal executive offices are located at New Orchard Road, Armonk, New York 10504 and its telephone number is (914) 499-1900. Sub has not conducted any business operations other than in connection with the transactions contemplated by the merger agreement.

Upon consummation of the merger, Sub will cease to exist, and Kenexa will continue as the surviving corporation.

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.

Our board of directors and management periodically review our long-term strategy and objectives in light of developments in the human capital management industry, which we refer to in this proxy statement as the HCM industry, in which we operate. Over the past several years, we have considered a range of strategic alternatives with a view to increasing shareholder value, including potential commercial and strategic business partnerships, potential acquisitions, and other business combination transactions, as well as the possible sale of the company.

In light of the acquisition of some of our competitors by well-capitalized companies, our board of directors asked Lazard Frères & Co. LLC, which we refer to in this proxy statement as Lazard, to present preliminary valuation and financial information and the implications of these acquisitions involving our competitors in the HCM industry, including the entrance, through acquisitions, of large, well-capitalized competitors (such as SAP, Oracle and Salesforce), as well as an overview and analysis of potential acquirers of us. On February 29, 2012, Lazard, which in the past provided certain investment banking services to us, gave this presentation at a meeting of our board of directors. At that meeting, the board did not determine to take any action respecting strategic alternatives and did not engage Lazard to provide additional investment banking services to us.

In November 2011, representatives of IBM contacted us to discuss a potential commercial relationship. From December 2011 through March 2012, we and IBM held periodic discussions regarding a potential commercial relationship. On March 12, 2012, we and IBM executed a non-disclosure agreement. On June 18, 2012, a representative of IBM contacted Nooruddin (Rudy) S. Karsan, our chairman and chief executive officer, to request a meeting to discuss the terms of a potential relationship in more detail.

On June 20, 2012, Mr. Karsan met with representatives of IBM to discuss the business and strategic plans of both companies respecting the HCM industry. At that meeting, representatives of IBM expressed interest in a potential acquisition of us and the parties discussed potential business opportunities and synergies as a combined company. Also at that meeting, representatives of IBM informed Mr. Karsan that IBM would be interested in retaining certain members of our management following an acquisition of us.

On June 22, 2012, Mr. Karsan, Troy Kanter, a director and our president and chief operating officer, and Donald Volk, our chief financial officer, attended a meeting with representatives of IBM to discuss our business, product and strategic plans. At that meeting, further discussions were held regarding potential business opportunities and synergies as a combined company and IBM indicated that it would be submitting a non-binding letter of interest to acquire us.

Also on June 22, 2012, Mr. Karsan contacted a representative of Lazard to discuss retaining Lazard as our financial advisor in connection with a potential acquisition by IBM.

On June 25, 2012, a representative of IBM provided a non-binding letter of interest to Mr. Karsan to acquire us for $41.50 per share, subject to an exclusivity agreement requiring a 75-day exclusivity period. Later that day, our board of directors held a telephonic meeting. Our board of directors reviewed its fiduciary duties under Pennsylvania law in the context of its consideration of IBM’s non-binding letter of interest. Representatives of Lazard discussed preliminary valuation considerations respecting IBM’s offer, as well as the benefits and risks of soliciting acquisition interest from third parties regarding a potential transaction with us. In this context, our board of directors discussed recent transactions in the human capital management industry, the fact that no other parties had expressed an interest in acquiring us, and the potential benefits and risks to us of continuing as an independent company. Following discussion of these matters, our board of directors determined that pursuing and considering the proposed transaction by IBM was in the best interests of the company and our shareholders.

Our board of directors authorized the engagement of Lazard as our financial advisor following disclosure by Lazard of its relationships with IBM, and authorized Lazard to convey to IBM that its proposed acquisition price of $41.50 per share was too low and the length of the required exclusivity period was too long.

On June 26, 2012, representatives of Lazard contacted a representative of IBM to confirm that neither the proposed purchase price of $41.50 per share nor the length of the required exclusivity period was supported by our board of directors. Representatives of Lazard discussed the rationales for a higher purchase price and a reduced exclusivity period. The representative of IBM discussed the merits of the proposed purchase price, including the fact that it represented a significant premium to both our current and all-time high stock prices and the comparability of us to our competitors acquired in recent transactions in the HCM industry.

Also on June 26, 2012, the representative of IBM provided Mr. Karsan a revised exclusivity agreement, which included an increase in the offer price to $46.00 per share, along with a shorter required exclusivity period through August 27, 2012. The representative of IBM subsequently indicated to the representative of Lazard that the offer represented IBM’s “best and final” offer.

On June 27, 2012, our board of directors held a telephonic meeting to discuss IBM’s revised non-binding letter of interest. Mr. Volk and representatives of Lazard also participated in the meeting. Barry Abelson, a director and partner with Pepper Hamilton LLP, which we refer to in this proxy statement as Pepper, our outside legal advisor, discussed the terms of IBM’s revised non-binding letter of interest and the proposed exclusivity period. Our board of directors discussed whether soliciting indications of interest from third parties regarding a potential transaction would be advisable, and determined that in light of the fact that no other parties had expressed an interest in acquiring us, such solicitation would be unlikely to yield positive results. It was also noted that IBM’s proposal required exclusivity, and that soliciting other potential acquirers could jeopardize the proposed IBM transaction and could significantly distract and disrupt our management team and business operations. After its discussions, our board of directors confirmed its determination that pursuing and considering the proposed transaction with IBM was in the best interests of the company and our shareholders and authorized us to agree to the terms of the revised exclusivity agreement. Our board of directors also confirmed its decision to engage Lazard as our financial advisor. Shortly after the conclusion of the meeting, we and IBM executed the exclusivity agreement. The exclusivity agreement generally provided that we and our representatives, through at least August 27, 2012 (after which date the exclusivity agreement could be terminated by either us or IBM), were prohibited from soliciting, encouraging, entering into or continuing discussions regarding a takeover proposal or furnishing information to a third party with respect to a takeover proposal.

On June 28, 2012, representatives of Pepper, Lazard and IBM discussed due diligence requirements and terms of a non-disclosure agreement and on June 29, 2012, we and IBM executed an amended and restated non-disclosure agreement.

On July 3, 2012, we and IBM, our respective outside legal advisors, Pepper and Cravath, Swaine & Moore LLP, which we refer to in this proxy statement as Cravath, began negotiations regarding the terms of the definitive merger agreement. Also on July 3, 2012, we established an electronic data room with requested due diligence documents and IBM began its business, financial and legal due diligence.

On July 10 and July 11, 2012, a representative of IBM and Mr. Karsan held further discussions regarding IBM retaining certain members of our management following an acquisition of us.

From July 10 through July 12, 2012, members of our management met with representatives of IBM at an offsite location to provide a product demonstration and allow representatives of IBM to conduct in-person due diligence. During July and August 2012, IBM conducted its business, financial and legal due diligence.

On July 19, 2012, a representative of IBM and Mr. Karsan held further discussions regarding IBM retaining certain members of our management following an acquisition of us.

Also on July 19, 2012, our board of directors met telephonically. Mr. Volk also participated in the meeting. Mr. Karsan reviewed developments regarding the proposed transaction with IBM. Mr. Abelson reviewed the final terms of the exclusivity agreement with IBM, indicating that exclusivity had been granted until at least August 27, 2012 (after which date the exclusivity agreement could be terminated by either us or IBM), as well as the final terms of our engagement of Lazard as our financial advisor. Mr. Abelson also reported on initial conversations with Cravath regarding certain merger agreement issues.

On July 27, 2012, a representative of IBM sent proposed offer letters to be entered into between IBM and certain of our key executives. The offer letters included proposed retention arrangements and were conditioned upon IBM completing the acquisition of our company.

Also on July 27, 2012, our board of directors met telephonically. Mr. Volk also participated in the meeting. Mr. Karsan updated our board of directors on our results of operations for the quarter ended June 30, 2012. Mr. Karsan also reviewed developments regarding the proposed transaction with IBM and indicated that conversations regarding the potential combined business were progressing satisfactorily.

On August 6, 2012, our board of directors met telephonically. Mr. Volk also participated in the meeting. Mr. Karsan reviewed developments regarding the proposed transaction with IBM indicating that the proposed transaction continued to proceed positively. Mr. Abelson updated our board of directors regarding IBM’s due diligence efforts. Mr. Abelson also indicated that, at the advice of Pepper, our senior management was engaging its own counsel in connection with their negotiations with IBM regarding employment with us following the completion of the proposed transaction.

On August 7, 2012, representatives of IBM discussed with Mr. Karsan the terms of the proposed offer letters to be entered into between IBM and certain of our key executives. Between August 7, 2012 and August 21, 2012, the terms of the offer letters were negotiated.

On August 9, 2012, Cravath sent Pepper an initial draft of the merger agreement. From August 9, 2012 until August 25, 2012, we and IBM, and our respective legal counsel, engaged in negotiations regarding the terms of the merger agreement.

On August 18, 2012, our board of directors met in person to consider the proposed transaction with IBM. Mr. Volk and representatives of Pepper and Lazard attended the meeting. In connection with the meeting, our board of directors received summaries of the proposed transaction and of the terms of the proposed offer letters to be entered into between IBM and certain of our key executives and drafts of the merger agreement and related documents. At the meeting, Mr. Karsan updated our board of directors on our business generally and on the status of negotiations with IBM. Representatives of Lazard reviewed its preliminary financial analysis of the proposed transaction. Our board of directors discussed whether the proposed transaction would be in the best interests of Kenexa. The representatives of Lazard confirmed that Lazard was prepared to render a customary fairness opinion on the proposed transaction if and when requested by our board of directors. Mr. Karsan discussed the positive impact of the proposed transaction on our shareholders and our other constituencies, including our employees, the communities in which we operate and our customers. Representatives of Pepper reviewed our directors’ fiduciary duties under Pennsylvania law as well as the terms of the proposed merger and related agreements, including agreements IBM was requiring from our directors and executive officers that would obligate them to vote any shares of our common stock they hold in favor of the proposed IBM transaction. After discussion, the unanimous sense of our board of directors was to seek to finalize the proposed transaction.

By August 24, 2012, IBM and certain members of our senior management entered into offer letters the effectiveness of which was conditioned upon IBM acquiring us.

On August 25, 2012, our board of directors met telephonically to consider the proposed transaction with IBM. Mr. Volk as well as representatives of Pepper and Lazard participated in the meeting. Mr. Karsan advised

that the negotiations with IBM were substantially complete and that the merger agreement for the transaction was ready for consideration and action by our board of directors. Mr. Abelson confirmed that due diligence matters have been concluded to IBM’s satisfaction and provided an update on the final terms of the merger and related agreements. Mr. Abelson reviewed the final terms of the offer letters (conditioned on IBM acquiring us) which had been entered into by IBM and certain members of our senior management. Representatives of Lazard reviewed Lazard’s final financial analysis of the proposed transaction and rendered its oral opinion, subsequently confirmed in writing, that, as of such date, and based upon and subject to the assumptions, procedures, factors, qualifications and limitations set forth in the opinion, the per share merger consideration to be paid to holders of our common stock (other than shares of our common stock held by IBM or Sub), in the merger was fair, from a financial point of view, to such holders. After our board of directors reviewed and discussed again the positive and potentially negative aspects of the merger, our board of directors unanimously approved the merger agreement and the merger, determining that it was in our best interests to do so.

The merger agreement was finalized and executed on August 25, 2012 and, on August 27, 2012, we and IBM issued press releases announcing the execution of the merger agreement.

At a meeting held on August 25, 2012, our board of directors unanimously determined that the terms and conditions of the merger and the merger agreement are fair to our shareholders and advisable and in the best interests of Kenexa. 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 “golden parachute” compensation that may be paid or become payable to our named executive officers in connection with the merger, including the agreements and understandings with us pursuant to which such compensation may be paid or become payable.

During the course of its deliberations on the merger, our board of directors held numerous meetings and consulted with our senior management, financial advisor and outside legal counsel, and reviewed, evaluated and considered numerous factors and a significant amount of information and data, including the following:

In reaching its decision to approve the merger agreement and the merger, and to recommend that our shareholders adopt the merger agreement, our board of directors determined that the following were positive reasons to support the merger agreement and the merger:

In reaching its decision to approve the merger agreement and the merger, and to recommend that our shareholders adopt the merger agreement, our board of directors considered the following potentially negative aspects of the merger, but nevertheless determined that the merger agreement and the merger are advisable to and in the best interests of Kenexa:

The foregoing discussion of the information and factors considered by our board of directors in reaching its conclusion and recommendation is not intended to be exhaustive, but includes the material factors considered by our board of directors. In view of the wide variety of factors considered in connection with its evaluation of the merger and complexity of these matters, our board of directors did not find it practicable to, and did not attempt to, quantify, rank or assign any relative or specific weights to the various factors considered in reaching its determination and making its recommendation. In addition, individual directors may have given weight to different factors. Our board of directors considered all of the foregoing factors, as well as any others that are not listed, as a whole 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 shareholders vote “FOR” the adoption of the merger agreement.

We retained Lazard to act as our financial advisor and to render an opinion to our board of directors as to the fairness, from a financial point of view, to holders of our common stock of the consideration to be paid to such holders in the merger. On August 25, 2012, Lazard rendered its oral opinion to our board of directors, subsequently confirmed in writing, that, as of such date, and based upon and subject to the assumptions, procedures, factors, qualifications and limitations set forth therein, the per share merger consideration to be paid

to holders of our common stock other than shares of our common stock held by excluded holders in the merger was fair, from a financial point of view, to such holders.

Lazard’s opinion was directed to our board of directors for the information and assistance of our board of directors in connection with its evaluation of the merger and only addressed the fairness, from a financial point of view, to holders of our common stock (other than the excluded holders) of the per share merger consideration to be paid to such holders in the merger as of the date of Lazard’s opinion. We did not request Lazard to consider, and Lazard’s opinion did not address, the relative merits of the merger as compared to any other transaction or business strategy in which we might engage or the merits of the underlying decision by us or our board of directors to engage in the merger. Lazard’s opinion was not intended to and does not constitute a recommendation to any holder of our common stock as to how such holder should vote or act with respect to the merger or any matter relating thereto. Lazard’s opinion was necessarily based on economic, monetary, market and other conditions as in effect on, and the information made available to Lazard as of, the date of Lazard’s opinion. Lazard assumed no responsibility for updating or revising its opinion based on circumstances or events occurring after the date of Lazard’s opinion. Lazard’s opinion did not express any opinion as to the price at which shares of our common stock may trade at any time subsequent to the announcement of the merger.

The following is a summary of Lazard’s opinion. We encourage you to read Lazard’s written opinion carefully in its entirety.

Lazard assumed and relied upon the accuracy and completeness of the foregoing information, without independent verification of such information. Lazard did not conduct any independent valuation or appraisal of any of our assets or liabilities (contingent or otherwise) or IBM’s or concerning our solvency or fair value or IBM’s, and Lazard was not furnished with any such valuation or appraisal. With respect to the financial forecasts utilized in Lazard’s analyses, Lazard assumed, with our consent, that they were reasonably prepared on bases reflecting the best currently available estimates and judgments as to our future financial performance. Lazard assumed no responsibility for and expressed no view as to such forecasts or the assumptions on which they were based.

In connection with its engagement, Lazard was not authorized to, and Lazard did not, solicit indications of interest from third parties regarding a potential transaction with us, nor was Lazard requested to consider, and its opinion does not address, the relative merits of the merger as compared to any other transaction or business strategy in which we might engage or the merits of the underlying decision by us to engage in the merger.

In rendering its opinion, Lazard assumed, with our consent, that the merger would be consummated on the terms described in the merger agreement, without any waiver or modification of any material terms or conditions. Our representatives advised Lazard, and Lazard assumed, that the merger agreement, when executed, would conform to the draft reviewed by Lazard in all material respects. Lazard also assumed, with our consent, that obtaining the necessary governmental, regulatory or third party approvals and consents for the merger would not have an adverse effect on us, IBM or the merger. Lazard’s opinion did not address any legal, tax, regulatory or accounting matters, as to which Lazard understood that we obtained such advice as we deemed necessary from qualified professionals. Lazard expressed no view or opinion as to any terms or other aspects (other than the per share merger consideration to the extent expressly specified in Lazard’s opinion) of the merger, including, without limitation, the form or structure of the merger or any shareholder, voting, non-competition, non-solicitation or other agreements or arrangements entered into in connection with, or contemplated by, the merger. In addition, Lazard expressed no view or opinion as to the fairness of the amount or nature of, or any other aspects relating to, the compensation to, or any agreements entered into with IBM by, any officers, directors or employees of any parties to the merger, or class of such persons, relative to the per share merger consideration or otherwise.

The following is a summary of the material financial analyses and reviews that Lazard deemed appropriate in connection with rendering its opinion. The summary of Lazard’s analyses and reviews provided below is not a complete description of the analyses and reviews underlying Lazard’s opinion. The preparation of a fairness opinion is a complex process involving various determinations as to the most appropriate and relevant methods of analysis and review and the application of those methods to particular circumstances, and, therefore, is not readily susceptible to summary description. Considering selected portions of the analyses and reviews or the summary set forth below, without considering the analyses and reviews as a whole, could create an incomplete or misleading view of the analyses and reviews underlying Lazard’s opinion.

In arriving at its opinion, Lazard considered the results of all of its analyses and reviews and did not attribute any particular weight to any factor, analysis or review considered by it; rather, Lazard made its determination as to fairness on the basis of its experience and professional judgment after considering the results of all of its analyses and reviews.

For purposes of its analyses and reviews, Lazard considered industry performance, general business, economic, market and financial conditions and other matters, many of which are beyond our control. No company, business or transaction used in Lazard’s analyses and reviews as a comparison is identical to us or the merger, and an evaluation of the results of those analyses and reviews is not entirely mathematical. Rather, the analyses and reviews involve complex considerations and judgments concerning financial and operating characteristics and other factors that could affect the acquisition, public trading or other values of the companies, businesses or transactions used in Lazard’s analyses and reviews. The estimates contained in Lazard’s analyses and reviews and the ranges of valuations resulting from any particular analysis or review are not necessarily indicative of actual values or predictive of future results or values, which may be significantly more or less favorable than those suggested by Lazard’s analyses and reviews. In addition, analyses and reviews relating to the value of companies, businesses or securities do not purport to be appraisals or to reflect the prices at which companies, businesses or securities actually may be sold. Accordingly, the estimates used in, and the results derived from, Lazard’s analyses and reviews are inherently subject to substantial uncertainty.

The summary of the analyses and reviews provided below includes information presented in tabular format. In order to fully understand Lazard’s analyses and reviews, the tables must be read together with the full text of each summary. The tables alone do not constitute a complete description of Lazard’s

analyses and reviews. Considering the data in the tables below without considering the full description of the analyses and reviews, including the methodologies and assumptions underlying the analyses and reviews, could create a misleading or incomplete view of Lazard’s analyses and reviews.

Except as otherwise noted, the following quantitative information, to the extent that it is based on market data, is based on market data as it existed on or before August 24, 2012 and is not necessarily indicative of current market conditions.

Lazard reviewed and analyzed selected public companies that it viewed as reasonably comparable to us. Consistent with its standard practices, in the course of its comparable public companies analysis, Lazard reviewed and analyzed certain financial information, valuation multiples and market trading data relating to selected comparable public companies in the SaaS industry. Lazard then compared such information to the corresponding information for us. In its analysis, Lazard considered industry performance, general business, economic, market and financial conditions and other matters.

The analysis indicated the following global multiples for all of the companies listed above:

Based on the foregoing and Lazard’s professional judgment, Lazard derived an enterprise value to estimated CY 2012 revenue multiple reference range of 2.0x to 3.0x. Lazard applied such range to our estimated CY 2012 revenue which was provided in our management projections. Lazard then calculated an implied transaction value reference range for us which resulted in a range of implied prices per share of our common stock from $26.92 to $38.99.

Using the same analysis and Lazard’s professional judgment, Lazard also calculated an enterprise value to estimated CY 2013 revenue multiple reference range of 2.0x to 2.5x. Lazard applied such range to our estimated CY 2013 revenue which was provided in our management projections. Lazard then calculated an implied transaction value reference range for us which resulted in a range of implied prices per share of our common stock from $30.69 to $37.65.

Using the same analysis and Lazard’s professional judgment, Lazard also calculated an enterprise value to estimated CY 2013 unlevered free cash flow multiple reference range of 16.0x to 22.0x. Lazard applied such

range to our estimated CY 2013 unlevered free cash flow which was provided in our management projections. Lazard then calculated an implied transaction value reference range for us which resulted in a range of implied prices per share of our common stock from $35.67 to $47.98.

Lazard reviewed and analyzed certain publicly available financial information for selected recent precedent merger transactions in the human capital management software, which we may refer to in this proxy statement as HCM software, and SaaS industries and compared such information to the corresponding information for the merger. The precedent transactions reviewed were:

Using publicly available information and market data, Lazard calculated and analyzed the enterprise value in each of the selected precedent transactions as a multiple of each target company’s revenues for the last twelve months, or LTM, with respect to the date of announcement of the transaction based on publicly available information as of that date. The analysis indicated the following multiples for each of the two categories of precedent transactions:

Based on the median multiples for each of the two categories of precedent transactions, Lazard calculated an enterprise value to LTM revenue multiple reference range of 3.7x to 4.4x and applied such range to our LTM revenue as of June 30, 2012. Lazard then calculated an implied transaction value reference range for us which resulted in a range of implied prices per share of our common stock from $42.61 to $50.53.

Lazard conducted a discounted cash flow analysis based on financial projections for our business produced by our management. The analysis estimated the present value of expected future cash flows from CY 2012 to CY 2017 and a terminal value. In its analysis, Lazard utilized discount rates to reflect the risk of the estimated cash flows and company size as compared to broader market risk. The terminal values were based on perpetual growth rates. For its calculations, Lazard used discount rates ranging from 12.125% to 12.375%, and a perpetual growth rate range of 3.5% to 4.5%, which resulted in a range of implied enterprise values for us. Lazard then calculated an implied transaction value reference range for us which resulted in a range of implied prices per share of our common stock of $42.97 to $48.44.

Lazard performed a premiums paid analysis based on the premiums paid, where applicable, in selected HCM software transactions and selected SaaS transactions. These transactions have been listed in the “Precedent Transactions Analysis” section.

The analysis was based on the one-day implied premiums paid in the selected precedent transactions. Lazard calculated the implied premium paid in each transaction by comparing the per share offer price at the time of the announcement of each transaction to the target company’s stock price one day prior to the announcement of the transaction.

Based on the foregoing, Lazard applied the median premium of 21% for selected HCM software precedent transactions and the median premium of 40% for selected SaaS precedent transactions to the closing price of our common stock as of August 24, 2012, the last full trading day before the execution of the merger agreement. Based on the foregoing, Lazard calculated an implied price per share of our common stock of $39.22 and $45.20, respectively.

In connection with Lazard’s services as our financial advisor, we agreed to pay Lazard an aggregate fee of $15 million, $2 million of which was payable upon the delivery of Lazard’s opinion and $13 million of which is contingent upon the consummation of the merger. We also agreed to reimburse Lazard for certain expenses incurred in connection with Lazard’s engagement and to indemnify Lazard and certain related persons under certain circumstances against certain liabilities that may arise from or relate to Lazard’s engagement, including certain liabilities under U.S. federal securities laws.

Lazard, as part of its investment banking business, is continually engaged in the valuation of businesses and their securities in connection with mergers and acquisitions, negotiated underwritings, secondary distributions of listed and unlisted securities, private placements, leveraged buyouts, and valuations for estate, corporate and other purposes. Lazard and Lazard Capital Markets LLC (an entity indirectly owned in large part by current and former managing directors of Lazard) have in the past provided certain investment banking services to us and Lazard in the past provided and currently is providing certain investment banking services to IBM, for which Lazard and Lazard Capital Markets LLC have received and may receive compensation, including, during the past two years, Lazard acting as our financial advisor in connection with our acquisition of Salary.com, Inc. in October 2010, Lazard Capital Markets LLC serving as our joint book-runner on our follow-on equity offering in May 2011 and Lazard acting as financial advisor to IBM in connection with its sale of its Retail Store Solutions business in August 2012. In addition, in the ordinary course of their respective businesses, Lazard, Lazard Capital Markets LLC and their respective affiliates may actively trade securities of us and IBM for their own accounts and for the accounts of their customers and, accordingly, may at any time hold a long or short position in such securities, and may also trade and hold securities on behalf of us and IBM. The issuance of Lazard’s opinion was approved by the opinion committee of Lazard.

Lazard is an internationally recognized investment banking firm providing a full range of financial advisory and other services. Lazard was selected to act as our financial advisor because of its qualifications, expertise and reputation in investment banking and mergers and acquisitions, as well as its familiarity with our business.

Lazard conducted the analyses and reviews summarized above for the purpose of providing an opinion to our board of directors as to the fairness, from a financial point of view, to the holders of our common stock (other than the excluded holders) of the per share merger consideration to be paid to such holders in the merger. Lazard did not recommend any specific consideration to our board of directors or any other person or indicate that any given consideration constituted the only appropriate consideration for the merger.

Lazard’s opinion was one of many factors considered by our board of directors. Consequently, the summary of the analyses and reviews provided above should not be viewed as determinative of the opinion of our board of directors with respect to the per share merger consideration or of whether our board of directors would have been willing to recommend a different transaction or determine that a different per share merger consideration was fair. Additionally, Lazard’s opinion is not intended to confer any rights or remedies upon any of our shareholders, employees or creditors.

We do not make public forecasts as to future performance or earnings beyond the current quarter and current fiscal year 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 Lazard in connection with its financial analysis of the merger consideration (see “—Opinion of Lazard Frères & Co. LLC” beginning on page 25) and provided to IBM, (except unlevered free cash flow). The company projections consisted of financial forecasts for the fiscal years ending December 31, 2012, 2013, 2014, 2015, 2016 and 2017. The company projections, while

presented with numerical specificity necessarily, were based on numerous estimates, variables and assumptions that are inherently uncertain and many of which are beyond our control. Because the projections cover multiple years, by their nature, they become subject to greater uncertainty with each successive year. The assumptions upon which the projections were based necessarily involve judgments with respect to, among other things, future economic, competitive and regulatory conditions and financial market conditions, all of which are difficult or impossible to predict accurately and many of which are beyond our control.

The financial forecasts for 2012 through 2017 fiscal years included in the company projections were as follows:

Non-GAAP revenue consists of GAAP revenue and the effect of the write down of the deferred revenue associated with purchase accounting for certain acquisitions. This effect is added back to GAAP revenue because we believe its inclusion provides a more accurate depiction of total revenue. Non-GAAP EBIT consists of GAAP earnings before interest and taxes plus non-cash stock-based compensation, amortization of acquired intangibles and restructuring charges. Non-GAAP EBITDA consists of GAAP earnings before interest, taxes, depreciation and amortization plus non-cash stock-based compensation and restructuring charges. Non-GAAP unlevered free cash flow refers to free cash flow without the effect of interest income and interest expense, which we record in other income / expense. Non-GAAP unlevered free cash flow consists of cash flow from operations less capital expenditures and tax-effected net interest income. Non-GAAP net income refers to non-GAAP net income available to common shareholders. Non-GAAP net income consists of GAAP net income plus tax-effected non-cash stock-based compensation, amortization of acquired intangibles and restructuring charges. Non-GAAP revenue, gross profit, EBIT, EBITDA, net income and earnings per share (but not unlevered free cash flow) are measures that are used by our management as supplemental financial measurements to evaluate our operational trends and should not be considered as alternatives to revenue, gross profit, net income or earnings per share as indicators of our operating performance. Non-GAAP revenue, gross profit, EBIT, EBITDA, net income, earnings per share and unlevered 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 financial forecasts above are included in this proxy statement to provide our shareholders access to certain nonpublic information considered by our board of directors in connection with its evaluation of the merger, provided to Lazard in connection with its opinion to our board of directors, as more fully described in the section entitled “—Opinion of Lazard Frères & Co. LLC” beginning on page 25, and provided to IBM (except unlevered free cash flow) for the purpose of allowing it to evaluate the merger.

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 SEC 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 quarter ended June 30, 2012. Our shareholders should review our Quarterly Report on Form 10-Q for the quarter ended June 30, 2012 to obtain this information. See “Where You Can Find More Information” beginning on page 73.

The inclusion of this information should not be regarded as an indication to any shareholder 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 shareholder 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 COMPANY PROJECTIONS, WE UNDERTAKE NO OBLIGATIONS TO UPDATE, OR PUBLICLY DISCLOSE ANY UPDATE TO, THESE COMPANY PROJECTIONS 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 shareholders of ours generally, pursuant to certain agreements between such directors and executive officers and us and, in the case of certain of the executive officers, pursuant to the Offer Letters. These interests are described below and may be different from, or in conflict with, your interests as one of our shareholders. 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 non-employee directors are entitled to certain equity acceleration benefits in connection with the merger, as described below in “—Treatment of Equity Awards Held by Our Non-Employee Directors” on page 34.

Because neither Mr. Karsan nor Mr. Kanter has received an Offer Letter, their employment arrangements will remain in effect following the merger. The Change in Control Plan provides for certain severance and equity acceleration benefits, as described below in “—Kenexa Change in Control Severance Plan” on page 34.

Messrs. Volk and Jones will be entitled to the equity acceleration each is entitled to under the Change in Control Plan; however, because they have each received and accepted an Offer Letter, these Offer Letters will supersede and replace their existing severance entitlements under the Change in Control Plan. The Offer Letters will be effective upon the closing of the merger and will provide certain transition and severance benefits to these individuals, as described below in “—IBM Offer Letters” on page 34.

Mr. Restivo has received and accepted an Offer Letter from IBM. This Offer Letter will supersede and replace his existing employment arrangement with us, including Mr. Restivo’s benefits under the Change in Control Plan. The Offer Letter will be effective upon the closing of the merger and will provide certain retention, severance and equity compensation benefits to Mr. Restivo, as described below in “—IBM Offer Letters” on page 34.

Each of Messrs. Karsan, Kanter, Volk, Restivo and Jones has entered into a non-competition and non-solicitation agreement with IBM that will become effective upon the closing of the merger, as described below in “—Non-Competition Agreements” on page 36.

Pursuant to the terms of the merger agreement and agreements evidencing equity awards awarded to our non-employee directors, all of the then-unvested options and restricted stock held by each of Messrs. Abelson, Konen, Nies and Pinola, Ms. Booth and Ms. Maddox will become fully vested at the effective time of the merger. The general treatment of options and restricted stock in the merger, including such awards held by our non-employee directors, is described below under “—Treatment of Outstanding Stock Options” and “—Treatment of Outstanding Restricted Stock” beginning on pages 42 and 43, respectively.

Pursuant to the Change in Control Plan, Messrs. Karsan and Kanter are entitled to cash severance and pro-rata bonus payments (for the year in which the applicable termination occurs), payable if the executive is terminated without “cause” or resigns for “good reason” (as such terms are defined in the Change in Control Plan) within two years following the merger. Upon such a termination of employment and contingent upon the executive’s execution of a standard release in favor of Kenexa, the executive would receive (A) a lump-sum payment equal to 1.75 times the sum of (i) the executive’s base salary and (ii) the executive’s target bonus opportunity for the fiscal year in which the termination occurs and (B) a payment of a pro-rata annual bonus for the year in which the termination occurs, determined and paid at the same time as other employee bonuses are paid with respect to such year. Although Messrs. Restivo, Volk and Jones were eligible to receive the severance benefits under the Change in Control Plan as described above in “—Overview” on page 33, such benefits were waived in connection with their acceptance of the Offer Letters.

Under the Change in Control Plan, all unvested equity and equity-based awards will accelerate and become fully vested immediately prior to (and contingent on) the occurrence of a “change in control” (as such term is defined in the Change in Control Plan). The closing of the merger will constitute a “change in control” within the meaning of the Change in Control Plan. Each of Messrs. Karsan, Kanter, Volk and Jones will be entitled to such accelerated vesting of their respective unvested equity and equity-based awards pursuant to the Change in Control Plan. Mr. Restivo waived this benefit in connection with his acceptance of his Offer Letter.

Each of Messrs. Volk, Restivo and Jones has received and accepted an Offer Letter that is conditioned upon the closing of the merger and the executive officer’s continued employment with us through the closing of the

merger. Upon the closing of the merger and the effectiveness of such Offer Letters, each of Messrs. Volk, Restivo and Jones will no longer be entitled to any payments or benefits upon termination of employment under their existing arrangements with us, including the Change in Control Plan, other than as described in their respective Offer Letters. Each executive officer’s employment by IBM is “at will” and may be terminated at any time for any reason, subject to the obligations described below and applicable law. Pursuant to Messrs. Volk’s and Jones’ Offer Letters, it is anticipated that their employment will end on the 12-month anniversary of the closing of the merger, unless they are offered and accept continuing employment with IBM.

Salary and Incentive Compensation. Mr. Volk’s Offer Letter provides for a gross monthly salary of $44,792 upon his transition to IBM’s payroll, and Mr. Jones’s Offer Letter provides for a gross monthly salary of $31,959. Messrs. Volk and Jones will not be entitled to participate in any IBM cash incentive programs. Mr. Restivo’s Offer Letter provides that the base salary and target cash incentive opportunity to which he will be entitled upon his transition to IBM’s payroll will be determined by IBM following the closing of the merger; however, during the 24-month period following such closing, neither his base salary nor his target total cash opportunity will be reduced from the amounts in effect as of immediately prior to the closing.

Treatment of Kenexa Equity Awards. The general treatment of options and restricted stock units in the merger, including such awards held by our executive officers, is described below under “—Treatment of Outstanding Stock Options” beginning on page 42 and “—Treatment of Outstanding Restricted Stock Units” beginning on page 42. Pursuant to Mr. Restivo’s Offer Letter, Mr. Restivo waived accelerated vesting of his Kenexa equity awards in connection with the closing of the merger. In addition, pursuant to his Offer Letter and subject to execution of IBM’s standard release of claims, if Mr. Restivo’s employment is terminated by IBM without “cause” (as described below) or due to Mr. Restivo’s death or disability (the latter as described in his Offer Letter) prior to the final vesting date with respect to converted Kenexa equity awards, all of the converted Kenexa equity awards held by Mr. Restivo that are unvested as of such date will vest in full.

Transition Program. Under the terms of each of Messrs. Volk’s and Jones’s Offer Letters, Messrs. Volk and Jones will be entitled to participate in a transition program pursuant to which they will be entitled to receive a cash payment equal to, with respect to Mr. Volk, $1,275,000 and, with respect to Mr. Jones, $792,000, payable as soon as practicable following the 12-month anniversary of the closing of the merger, subject to continued employment through such date and the achievement of certain milestones set forth in their respective Offer Letters. If Messrs. Volk’s or Jones’s employment is terminated by IBM without “cause” (as described below), or due to death or disability (the latter as described in the Offer Letters), prior to the one-year anniversary of the closing of the merger, the executive will be entitled to the full amount of his cash payment under the transition program, subject to the execution of IBM’s standard release of claims.

Retention Program. Under the terms of Mr. Restivo’s Offer Letter, Mr. Restivo will be entitled to participate in a retention program pursuant to which he will be eligible to receive an aggregate of $1,000,000 payable following each of three milestone periods, subject to continued employment through the applicable milestone period and the achievement of certain milestones set forth in his Offer Letter. The first milestone period begins on the closing date of the merger and ends on the six-month anniversary of the closing date; the second milestone period begins on the six-month anniversary of the closing date and ends on the one-year anniversary of the closing date; and the third milestone period begins on the one-year anniversary of the closing date and ends on the two-year anniversary of the closing date. Up to ten percent of the aggregate bonus may be paid at the end of the first milestone period; up to 20% may be paid at the end of the second milestone period; and up to 70% may be paid at the end of the third milestone period. If Mr. Restivo’s employment is terminated by IBM without “cause” (as described below) after the one-year anniversary, but prior to the two-year anniversary, of the closing of the merger or due to his death or disability (the latter as described in his Offer Letter) prior to the two-year anniversary of the closing of the merger, he will be entitled to receive the retention payment for the then-applicable milestone period, subject to his execution of IBM’s standard release of claims.

Severance Payment. Mr. Restivo’s Offer Letter provides that if Mr. Restivo’s employment is terminated by IBM without “cause” (as described above) on or prior to the one-year anniversary of the closing of the merger, he

will be entitled to (i) a lump-sum cash payment equal to $400,000 and (ii) a pro-rata annual bonus for the year in which his employment is terminated, in each case contingent on his executing IBM’s standard release of claims.

Definition of “Cause.” “Cause” is described in each Offer Letter as cause, as determined by IBM in accordance with its standard policies and procedures, which includes, among other things, any violation of IBM policy and/or failure to perform satisfactorily, and without regard to how “cause” is defined in any plan, policy or program, any offer letter, any agreement between the executive and Kenexa or any amendment thereto.

Each of Messrs. Karsan, Kanter, Volk, Restivo and Jones has executed a non-competition agreement with IBM, which provides that for certain periods following termination of employment and following the closing of the merger, each will be subject to restrictive covenants that generally prohibit them, in any capacity, directly or indirectly, from having any relationship with a business that involves engaging or assisting in the design, development, distribution, support, marketing, consulting on, licensing or selling software, solutions or services that include or relate to (i) SaaS, hosted and on-premise based Human Capital Management and Integrated Human Capital Management software, solutions, content, data and services, or (ii) any affiliated, attendant or associated products or services, including without limitation outsourcing or consulting services, as they relate to human resource sourcing, talent pools, recruiting, recruitment process, outsourcing, applicant tracking, interviewing, hiring and other human resources related functions. During the restricted period, such agreement also prohibits each executive from soliciting customers, employees and consultants of Kenexa or the IBM business unit into which Kenexa will be integrated, and provides for certain no-hire and non-disruption restrictions.

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

The table below sets forth, as of December 1, 2012, for each of our directors and executive officers, the total number of all unvested, in-the-money stock options held, the dollar value of such stock options, the total number of all vested and unvested, in-the-money stock options held and the dollar value of such stock options. The first two columns of the table below only include the number and value of the options for which vesting will be accelerated automatically in connection with the closing of the merger and does not take into account any additional acceleration of stock option vesting that could occur upon termination of service under specified circumstances pursuant to the Offer Letters; however, see “—Potential Payments in Connection with a Change in Control” beginning on page 39 below.

The table below sets forth, as of December 1, 2012, for each of our directors and executive officers, the number of shares of restricted stock and restricted stock units the vesting of which will accelerate at the closing of the merger, the dollar value of such restricted stock and restricted stock units, the total number of all shares of restricted stock and restricted stock units held and the dollar value of such restricted stock and restricted stock units. The first two columns of the table below only include the number and value of the restricted stock and restricted stock units that will be accelerated automatically in connection with the closing of the merger and does not take into account any additional acceleration of vesting that could occur upon termination of service under specified circumstances pursuant to the officers’ Offer Letters or Change in Control Plan; however, see “—Potential Payments in Connection with a Change in Control” beginning on page 39 below.

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 of our named executive officers in connection with the merger pursuant to employment arrangements with us (including the Change in Control Plan) and the Offer Letters described above, assuming (i) the consummation of the merger occurred on December 1, 2012, (ii) the price per share of our common stock is $46.00 and (iii) for purposes of estimating severance and equity acceleration benefits, the service of the named executive officer also terminated on such date under the circumstances described below.

The proposal to our shareholders with respect to the approval, on an advisory (non-binding) basis, of the “golden parachute” compensation that may be paid or become payable to our named executive officers in connection with the merger, including the agreements and understandings with us pursuant to which such compensation may be paid or become payable, requires the affirmative vote of the holders of a majority of votes cast by all Kenexa shareholders entitled to vote at the special meeting, provided that a quorum is present.

The surviving corporation will assume, and IBM will cause the surviving corporation and its successors and assigns to comply with and honor, all rights to indemnification, advancement of expenses and exculpation from liabilities for acts or omissions occurring at or prior to the effective time of the merger existing in favor of our and our subsidiaries’ current or former directors or officers as provided in our and their respective certificates of incorporation or bylaws (or comparable organizational documents) and any indemnification or other agreements as in effect on the date of the merger agreement.

IBM will obtain or will cause to be obtained as of the effective time of the merger a “tail” insurance policy with a claims period of six years from the effective time of the merger with respect to directors’ and officers’ liability insurance covering those persons who were, as of the date of the merger agreement, covered by our directors’ and officers’ liability insurance policy, for acts or omissions occurring prior to the effective time of the merger, on terms that are no less favorable than our policies in effect on the date of the merger agreement. Prior to the closing of the merger, IBM will prepay such insurance for the six-year period, but in no event will IBM or the surviving corporation be required to pay, with respect to the entire six-year period following the effective time of the merger, premiums for insurance which in the aggregate exceed 300% of the aggregate premiums paid by us for the period from June 23, 2012 to, and including, June 23, 2013 (or $975,891 in the aggregate).

listed on a national securities exchange. Consequently, since our common stock is currently listed on the NYSE, which is a national securities exchange, the holders of our common stock will not have the right to exercise dissenters’ rights in connection with the merger.

If the merger agreement is adopted and the merger is completed, holders of our common stock who voted against the adoption of the merger agreement will be treated the same as holders who voted for the adoption of the merger agreement and their shares will automatically be converted into the right to receive the $46.00 per share merger consideration.

Rollover Options. Subject to any provisions to the contrary in an Offer Letter, each outstanding and unexercised option to acquire shares of our common stock that will not be cancelled in the manner described in the preceding paragraph will be converted into an option to acquire, on substantially the same terms and conditions as were applicable to such option prior to the effective time of the merger, the number of shares of IBM’s common stock equal to the product of the number of shares of our common stock that are subject to such option and the exchange ratio, rounded down to the nearest whole share of IBM’s common stock. The exchange ratio is a fraction, the numerator of which is the merger consideration of $46.00 per share and the denominator of which is the average closing price per share of IBM’s common stock on the NYSE on the 20 trading days immediately preceding the closing date of the merger. The exercise price of such converted option per share of IBM’s common stock as of immediately following such conversion will be equal to the per share exercise price for the shares of our common stock purchasable pursuant to such option prior to the effective time of the merger divided by the exchange ratio, rounded up to the nearest whole cent.

Cash-Out Restricted Stock Units. Subject to any provisions to the contrary in an Offer Letter, each outstanding and unsettled restricted stock unit to the extent that such restricted stock unit either (i) is vested (or will vest in connection with the merger) or (ii) is held by any of our or our subsidiaries’ non-employee directors, consultants or independent contractors will be cancelled at the effective time of the merger and will be converted into the right of the holder thereof to receive in consideration for such cancellation an amount in cash, without interest and less any applicable withholding taxes, payable at or as soon as practicable following the effective time of the merger, equal to the product of the number of shares of our common stock that are subject to such restricted stock unit and the merger consideration of $46.00 per share.

Rollover Restricted Stock Units. Subject to any provisions to the contrary in an Offer Letter, each outstanding and unsettled restricted stock unit that will not be cancelled in the manner described in the preceding paragraph will be converted at the effective time of the merger into a restricted stock unit, subject to substantially the same terms and conditions as were applicable to the restricted stock unit prior to the effective time of the merger, with respect to a number of shares of IBM’s common stock equal to the product of the number of shares of our common stock underlying the restricted stock unit prior to the effective time of the merger and the exchange ratio (as described above) rounded down to the nearest whole share of IBM’s common stock.

Each outstanding share of restricted stock will be converted into the right to receive the merger consideration of $46.00 per share.

Under the merger agreement, the ESPP will be terminated no later than the last trading day prior to the effective time of the merger before the closing of the merger, and, if the ESPP remains in effect on the last trading day prior to the effective time of the merger, the amounts credited to the accounts of participants in the ESPP will be distributed to such participants as soon as practicable after the closing of the merger.

If the merger is completed, our common stock will be delisted from and will no longer be traded on the NYSE 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 our 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 our 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 our 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 mark-to-market method of accounting, controlled foreign corporations, passive foreign investment companies, U.S. expatriates, holders who acquired their Kenexa common stock through the exercise of options or otherwise as compensation, holders who hold their Kenexa common stock as part of a hedge, straddle, constructive sale or conversion transaction, and U.S. holders (as defined below) whose functional currency is not the U.S. dollar. 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 our 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 our 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 our common stock, you should consult your own tax advisor.

All holders should consult their own tax advisor 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 our common stock pursuant to the merger.

For purposes of this discussion, the term “U.S. holder” means a beneficial owner of our 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 our common stock that is not a U.S. holder.

The conversion of shares of our 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 in respect of the shares converted pursuant to the merger and such U.S. holder’s adjusted tax basis in the converted shares. 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 our 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 our 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 in respect of our common stock converted 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.

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 KENEXA SHAREHOLDERS. THE TAX CONSEQUENCES OF THE MERGER MAY VARY DEPENDING UPON THE PARTICULAR CIRCUMSTANCES OF EACH SHAREHOLDER. 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 Kenexa and IBM have each substantially complied with such request for additional information (unless this period is shortened pursuant to a grant of earlier termination). Kenexa and IBM filed 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 September 10 and September 11, 2012, respectively, and on September 18, 2012, we were informed that early termination of the waiting period was granted.

At any time before the effective time of the merger, notwithstanding the termination of the waiting period under the HSR Act, 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.

The completion of the merger is also subject to comparable notifications and review under the antitrust laws of various foreign jurisdictions. We and IBM intend to file notifications with the appropriate governmental entities in each of those jurisdictions. Some of these jurisdictions do not require regulatory approval, consent or agreement prior to completing the merger. With respect to jurisdictions that do require regulatory approval, consent or agreement prior to completing the merger, we and IBM expect to observe the applicable waiting periods prior to completing the merger. It is possible that any of the governmental entities with which notifications are filed may seek, as conditions for granting approval of the merger, various regulatory concessions. There can be no assurance that we and IBM will be able or willing to satisfy or comply with these conditions.

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 us or IBM. Such information can be found elsewhere in this proxy statement and in the other public filings we and IBM 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 us and IBM 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 us and IBM 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 shareholders, or may have been made for the purpose of allocating risk between us and IBM 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 us and IBM or their respective businesses.

Subject to the terms and conditions of the merger agreement and in accordance with Pennsylvania law, at the effective time of the merger, Sub, a wholly-owned subsidiary of IBM and a party to the merger agreement, will merge with and into us. We will survive the merger as a wholly-owned subsidiary of IBM and the separate corporate existence of Sub will cease. Our articles of incorporation as in effect immediately prior to the effective time of the merger will be amended by virtue of the merger to be identical to the articles of incorporation of Sub as in effect immediately prior to the effective time of the merger, except that Article I of such articles of incorporation shall be amended to read as follows: “The name of the corporation (hereinafter called the “Corporation”) is Kenexa Corporation.” The bylaws of Sub as in effect immediately prior to the effective time of the merger shall be the bylaws of the surviving corporation after the merger, until thereafter changed or amended as provided therein or by applicable law.

The merger will become effective upon the filing of articles of merger with the Department of State of the Commonwealth of Pennsylvania or at such later time as is agreed upon by IBM and us and specified in the articles of merger. The filing of the articles of merger will occur as soon as practicable on or after the date of closing, which will take place on a date to be specified by IBM, Sub and us which will be no later than the fifth business day after satisfaction or waiver of the conditions to the closing of the merger set forth in the merger agreement and described in this proxy statement, or at such other times as is agreed upon by IBM and us. Although we expect to complete the merger as soon as possible following the special meeting of our shareholders (if our shareholders adopt the merger agreement), we cannot specify when or assure that we and IBM 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 61.

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 or IBM) will be converted at the effective time of the merger into the right to receive $46.00 in cash, without interest and less any applicable withholding taxes.

Treatment of Stock Options, Restricted Stock Units, Restricted Stock and Purchase Rights

The exchange ratio is a fraction, the numerator of which is the merger consideration of $46.00 per share and the denominator of which is the average closing price per share of IBM’s common stock on the NYSE on the 20 trading days immediately preceding the closing date of the merger. The exercise price of such converted option per share of IBM’s common stock as of immediately following such conversion will be equal to the per share exercise price for the shares of our common stock purchasable pursuant to such option prior to the effective time of the merger divided by the exchange ratio, rounded up to the nearest whole cent.

Each outstanding share of restricted stock will be converted into the right to receive the merger consideration of $46.00 per share.

Surrender of Stock Certificates; Payment of Merger Consideration; Lost Certificates

Prior to the effective time of the merger, IBM will designate a paying agent and, from time to time after the effective time of the merger, IBM will make available to the paying agent funds in amounts as necessary for the payment of the merger consideration.

As soon as reasonably practicable after the effective time of the merger, the paying agent will mail to each person who was a holder of record of our common stock immediately prior to the effective time of the merger a letter of transmittal containing instructions for exchanging certificates representing such shares of our common stock. Such letter of transmittal will be accompanied by a substitute IRS Form W-9 or the applicable IRS Form W-8. After the effective time of the merger, each holder of a certificate previously representing such shares of our common stock will, upon surrender to the paying agent of a certificate, together with a properly completed letter of transmittal, be entitled to receive the merger consideration of $46.00 in cash, less any applicable withholding taxes, for each share of our common stock represented by such certificate.

No interest will be paid or shall accrue on the cash payable upon surrender of any such certificate. The cash paid upon surrender of any such certificate will be deemed to have been paid in full satisfaction of all rights pertaining to the shares of our common stock formerly represented by such certificate.

If any such certificate has been lost, stolen, defaced or destroyed, the paying agent or the surviving corporation, as the case may be, will pay the merger consideration with respect to each share of our common stock formerly represented by such certificate upon the making of an affidavit of that fact by the person claiming such certificate to be lost, stolen, defaced or destroyed and, if required by the surviving corporation, the posting by such person of a bond in an 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 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 certificates that formerly represented shares of our common stock. After that

point, shareholders will no longer be able to receive the merger consideration from the paying agent. Instead, they will be required to seek to obtain the merger consideration only from IBM and the surviving corporation and in so doing will be treated as general creditors with respect to the payment of any such merger consideration, without any interest thereon.

The merger agreement provides that 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 the earlier of their resignation or removal or until their respective successors are duly elected and qualified, as the case may be. At the closing, if requested by IBM, we shall deliver to IBM evidence reasonably satisfactory to IBM of the resignation of any or all of our directors and the directors of our subsidiaries, effective at the effective time of the merger.

We have made a number of representations and warranties to IBM and 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 is any state of facts, change, development, event, effect, condition, occurrence, action or omission that, individually or in the aggregate, is reasonably likely to:

provided that in no event will any of the following events, effects or circumstances be deemed either alone or in combination to constitute or be taken into account in determining whether there has been or would be, a material adverse effect:

IBM and 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 before the effective time of the merger, subject to certain exceptions, we will carry on our, and we will cause each of our subsidiaries to carry on their, business in the ordinary course consistent with past practice and use commercially reasonable efforts to comply with all applicable laws and, to the extent consistent therewith, use commercially reasonable efforts to keep available the services of present officers, software developers and other employees, to preserve assets and technology and relationships with customers, suppliers, licensors, licensees, distributors and others having material business dealings with us and our subsidiaries and to maintain franchises, rights and permits.

In addition, we have agreed, with specified exceptions, to various restrictions, including restrictions on our and our subsidiaries’ ability to:

Despite these general prohibitions, at any time prior to the adoption of the merger agreement by our shareholders and subject to the conditions described below, we may, and may permit and authorize our subsidiaries and our and our subsidiaries’ representatives to:

The merger agreement provides that neither our board of directors nor any committee of our board will, or will agree or resolve to take any of the following actions:

Notwithstanding the foregoing, subject to the conditions described below, our board of directors may, at any time prior to the adoption of the merger agreement by our shareholders, in response to a superior proposal (as defined in the merger agreement and as described below under this heading), effect an adverse recommendation change. Our board of directors may only effect an adverse recommendation change if:

The covenant in the merger agreement generally prohibiting us from soliciting takeover proposals does not prevent us from complying with Rule 14d-9 and 14e-2(a) promulgated under the Securities Exchange Act or from making any disclosure to our shareholders if our board of directors determines in good faith that failure so to disclose would be inconsistent with applicable law; provided, however, that in no event will we or our board of directors or any committee thereof take, agree or resolve to take any action with respect to an adverse recommendation change that is prohibited by the merger agreement.

A “takeover proposal” means any inquiry, proposal or offer from any person or group (other than IBM or Sub or their affiliates) relating to, or that could reasonably be expected to lead to, in one or a series of transactions, any merger, consolidation, business combination, recapitalization, liquidation or dissolution involving us or any direct or indirect acquisition, including by way of merger, consolidation, tender offer, exchange offer, stock acquisition, asset acquisition, binding share exchange, business combination, recapitalization, liquidation, dissolution, joint venture, license agreement or similar transaction, of:

A “superior proposal” means any binding bona fide unsolicited written offer of any person (other than IBM or Sub or their affiliates) which did not result from a breach of the nonsolicitation covenants contained in the merger agreement and that, if consummated, would result in such person or its shareholders acquiring, directly or indirectly:

which offer, in the reasonable good faith judgment of our board of directors, after consulting with a financial advisor of nationally recognized reputation and outside legal counsel, (i) provides a higher value to our shareholders than the consideration payable in the merger (taking into account all of the terms and conditions of such proposal and the merger agreement (including any changes to the terms of the merger agreement proposed by IBM in response to such superior proposal or otherwise)), (ii) is not subject to any financing condition or contingency and (iii) is reasonably capable of being completed, taking into account all financial, legal, regulatory and other aspects of such proposal.

We have agreed, subject to any applicable legal restraints, to convene and hold a shareholders meeting, for the purpose of the adoption of the merger agreement by our shareholders on the date that is 35 calendar days immediately following the date of mailing of the definitive proxy statement to our shareholders.

We are required to hold the special meeting of shareholders regardless of whether our board of directors determines prior to the date of such meeting that the merger agreement is no longer advisable, recommends that our shareholders reject the merger agreement or makes any other adverse recommendation change. Further, our obligation to hold the special meeting of shareholders will not be affected by the commencement, public proposal, public disclosure or communication to us or any other person of any takeover proposal.

We, IBM and Sub have each agreed to use commercially reasonable efforts to take, or cause to be taken, all actions that are necessary, proper or advisable to consummate and make effective the merger, including using commercially reasonable efforts to accomplish the following:

In connection with and without limiting the generality of the foregoing, we and our board of directors will, if any state takeover statute or similar statute or regulation, including the Pennsylvania Takeover Disclosure Law or Subchapters E, G, H, I or J of Chapter 25 of the Pennsylvania Business Corporation Law, is or becomes applicable to the merger agreement, the shareholder agreements or any of the merger and the other transactions contemplated by the merger agreement, including transactions under the shareholder agreements, take all actions necessary to ensure that the merger and the other transactions contemplated by the merger agreement and under the shareholder agreements may be consummated as promptly as practicable on the terms contemplated by the merger agreement and otherwise to minimize the effect of such statute or regulation on the merger agreement, the shareholder agreements, the merger and the other transactions contemplated by the merger agreement or under the shareholder agreements.

However, IBM and Sub are not obligated to agree to, and we and our subsidiaries will not without the prior written consent of IBM agree to, or proffer to, divest or hold separate, or enter into any licensing, business restriction or similar arrangement with respect to, any assets (whether tangible or intangible) or any portion of its, our or either of our or their subsidiaries’ businesses

Furthermore, IBM and its subsidiaries are not obligated to litigate or participate in the litigation of any suit, claim, action, investigation or proceeding brought by any governmental entity which:

We and IBM shall provide such assistance, information and cooperation to each other as is reasonably required to obtain any such actions, nonactions, waivers, consents, approvals, orders and authorizations and, in connection therewith, shall notify the other promptly following the receipt of any comments from any governmental entity and of any request by any governmental entity for amendments, supplements or additional information in respect of any registration, declaration or filing with, or notice to, such governmental entity.

Our, IBM’s and Sub’s obligations to effect the merger are subject to the satisfaction or waiver of the following conditions:

IBM’s and Sub’s obligations to effect the merger are further subject to the satisfaction by us or waiver by them of the following conditions:

Our obligations to effect the merger are subject to the further satisfaction by IBM and/or Sub or waiver by us of the following conditions:

The merger agreement may be terminated and the merger abandoned, whether before or after our shareholders approve the merger, under the following circumstances:

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

We will be required to pay a termination fee of $52 million to IBM and reimburse IBM for its expenses up to $5 million if:

The surviving corporation will assume, and IBM will cause the surviving corporation and its successors and assigns to comply with and honor, all rights to indemnification, advancement of expenses and exculpation from liabilities for acts or omissions occurring at or prior to the effective time of the merger existing in favor of our and our subsidiaries’ current or former directors or officers as provided in our and their respective organizational documents and any indemnification or other agreements as in effect on the date of the merger agreement.

In the event the surviving corporation or any of its successors or assigns consolidates with or merges into another entity and is not the continuing or surviving entity of such consolidation or merger or transfers all or substantially all of its properties and assets to another entity, or if IBM dissolves the surviving corporation, IBM will cause proper provision to be made so that the successors and assigns of the surviving corporation assume the obligations set forth above.

IBM will obtain or cause to be obtained as of the effective time of the merger a “tail” insurance policy with a claims period of six years from the effective time of the merger with respect to directors’ and officers’ liability insurance covering those persons who were, as of the date of the merger agreement, covered by our directors’ and officers’ liability insurance policy, for acts or omissions occurring prior to the effective time of the merger, on terms that are no less favorable than our policies in effect on the date of the merger agreement. Prior to the closing of the merger, IBM will prepay such insurance for the six-year period, but in no event will IBM or the surviving corporation be required to pay, with respect to the entire six-year period following the effective time of the merger, premiums for insurance which in the aggregate exceed 300% of the aggregate premiums paid by us for the period from June 23, 2012 to, and including, June 23, 2013 (or $975,891 in the aggregate).

Except as would violate applicable law, court process or securities exchange rules, we have agreed to consult with IBM prior to making any press release or other public statements with respect to the merger.

Except as would violate applicable law, we have agreed to give notice to IBM, promptly upon having knowledge, in writing of:

We have also agreed to provide IBM with the opportunity to participate in the defense of any litigation against us or our board of directors related to the merger or the other transactions contemplated by the merger agreement. Although we have not agreed to give IBM the right to direct the defense of any such litigation, we have agreed to obtain the prior written consent of IBM prior to settling or satisfying any such claim.

We, IBM and 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 shareholders, no amendment can be made that by law requires approval by our shareholders without the further approval of such shareholders.

We, IBM or Sub may extend the time for performance of any of the obligations or other acts of the other parties under the merger agreement, waive any inaccuracies in another party’s representations and warranties and waive compliance with any of the agreements or conditions contained in the merger agreement. However, after the adoption of the merger agreement by our shareholders, no waiver can be provided that by law requires approval by our shareholders without the further approval of such shareholders.

As a condition to IBM entering into the merger agreement, each of our directors and executive officers have executed and delivered to IBM a Shareholder Agreement, which we also refer to as a shareholder agreement, dated as of August 25, 2012, pursuant to which each such officer and director agreed, among other things, to vote the shares of our common stock of which such person is the record or beneficial owner in favor of the adoption of the merger agreement. At the close of business on the record date, these shareholders collectively beneficially own approximately 7.7% of the issued and outstanding shares of our common stock. In connection with the execution and delivery of the shareholder agreements, IBM did not pay these shareholders any consideration in addition to the consideration they may receive pursuant to the merger agreement in respect of their shares. Each of the shareholder agreements is substantially similar to the form of shareholder agreement attached as Exhibit A to the merger agreement.

Each such shareholder granted IBM and any designee of IBM an irrevocable proxy to vote the shareholder’s shares in favor of adoption of the merger agreement and otherwise in accordance with the shareholder agreement.

The following table sets forth information with respect to the beneficial ownership of our common stock as of September 13, 2012 for:

Beneficial ownership is determined in accordance with the rules of the SEC, and the information is not necessarily indicative of beneficial ownership for any other purpose. Except as indicated by footnote, to our knowledge, the persons and entities named in the table have sole voting and investment power with respect to all shares of common stock shown as beneficially owned by them, subject to applicable community property laws. Securities that may be beneficially acquired within 60 days of September 13, 2012, including shares subject to options exercisable within 60 days of September 13, 2012, and restricted stock units vesting within 60 days of September 13, 2012, are deemed to be beneficially owned by the person or entity holding such securities for the purpose of computing ownership of such person or entity, but are not treated as outstanding for the purpose of computing the ownership of any other person or entity. 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. The applicable percentages of beneficial ownership are based on 27,601,210 shares of common stock outstanding as of September 13, 2012 plus shares of common stock otherwise deemed outstanding under applicable SEC rules.

Unless otherwise indicated, the principal address of each of the shareholders named below is: c/o Kenexa Corporation, 650 East Swedesford Road, Second Floor, Wayne, Pennsylvania, 19087.

In the event that the number of shares of our 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, we may move to adjourn the special meeting in order to enable our board of directors to solicit additional proxies in favor of the adoption of the merger agreement. In that event, we will ask our shareholders to vote only upon the adjournment proposal and not on the other proposals discussed in this proxy statement.

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 the holders of a majority of votes cast by all Kenexa shareholders entitled to vote at the special meeting, provided that a quorum is present. However, if you are a shareholder 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 card or vote in person or a broker non-vote will not affect whether this matter has been approved, 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.

Kenexa’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, we are providing our shareholders with the opportunity to cast an advisory (non-binding) vote on the compensation that may be paid or become payable to our named executive officers in connection with the proposed merger pursuant to agreements and understandings with us, and the agreements and understandings with us pursuant to which such compensation may be paid or become payable. As required by those rules, we are asking our shareholders to adopt the following resolution:

RESOLVED, that the compensation that may be paid or become payable to Kenexa’s named executive officers in connection with the merger pursuant to agreements and understandings with Kenexa, and the agreements and understandings with Kenexa pursuant to which such compensation may be paid or become payable, as disclosed in the table in this proposal and as further described under the heading “The Merger—Interests of Kenexa’s Executive Officers and Directors in the Merger” beginning on page 33, are 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 IBM, however, is not subject to the advisory vote on golden parachute compensation but is described, inclusive of the potential payments and benefits under the Offer Letters, under the heading “The Merger—Interests of Kenexa’s Executive Officers and Directors in the Merger”, beginning on page 33 and in the table titled “Golden Parachute Compensation” beginning on page 39.

The following table sets forth the amount of payments and benefits that may be paid or become payable to each of Messrs. Karsan, Kanter, Volk, Restivo and Jones in connection with the merger pursuant to their employment arrangements with us, after giving effect to such executive’s waiver pursuant to an Offer Letter of any payments or benefits under an employment arrangement with us, assuming (i) the consummation of the merger occurred on December 1, 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 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 golden parachute compensation, and vice versa. Approval of this proposal is not a condition to completion of the proposed merger.

Because the vote on “golden parachute” compensation is only advisory in nature, it will not be binding on either us or IBM 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 the holders of a majority of votes cast by all Kenexa shareholders entitled to vote at the special meeting, provided that a quorum is present. However, if you are a shareholder 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.

Our board of directors unanimously recommends that our shareholders 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 shareholders residing at the same address, unless our shareholders 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 shareholder 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: Kenexa Corporation, 650 East Swedesford Road, Second Floor, Wayne, Pennsylvania 19087, Attention: Corporate Secretary, or call (866) 888-8121.

If the merger is completed there will be no public participation in any future meetings of our shareholders. However, if the merger is not completed, our shareholders will continue to be entitled to attend and participate in our shareholders meetings. Shareholder proposals submitted to us pursuant to Rule 14a-8 promulgated under the Securities Exchange Act for inclusion in our proxy statement and form of proxy for our 2013 Annual Meeting of Shareholders must be received by us no later than December 7, 2012 and must comply with the requirements of the proxy rules promulgated by the SEC.

The date on which the Closing occurs is referred to in this Agreement as the “Closing Date”.

SECTION 1.03. Effective Time of the Merger. Upon the terms and subject to the conditions set forth in this Agreement, as soon as practicable on or after the Closing Date, the parties shall properly file with the Department of State of the Commonwealth of Pennsylvania articles of merger (the “Articles of Merger”) in such form as is required by, and executed and acknowledged in accordance with, the relevant provisions of the PBCL. The Merger shall become effective at such date and time as the Articles of Merger are duly filed with the Department of State of the Commonwealth of Pennsylvania or, to the extent permitted by applicable Law, at such subsequent date and time as Parent and the Company shall agree and specify in the Articles of Merger. The date and time at which the Merger becomes effective is referred to in this Agreement as the “Effective Time”.

SECTION 1.05. Articles of Incorporation and Bylaws. (a)The articles of incorporation of the Company as in effect immediately prior to the Effective Time shall be amended by virtue of the Merger at the Effective Time to be identical to the articles of incorporation of Sub as in effect immediately prior to the Effective Time, except that Article I of such articles of incorporation shall be amended to read as follows: “The name of the corporation (hereinafter called the “Corporation”) is Kenexa Corporation.”

(b) The bylaws of Sub as in effect immediately prior to the Effective Time shall be the bylaws of the Surviving Corporation until thereafter changed or amended as provided therein or by applicable Law.

SECTION 1.06. Directors. The directors of Sub immediately prior to the Effective Time shall be the directors of the Surviving Corporation until the earlier of their resignation or removal or until their respective successors are duly elected and qualified, as the case may be.

SECTION 1.07. Officers. The officers of Sub immediately prior to the Effective Time shall be the officers of the Surviving Corporation until the earlier of their resignation or removal or until their respective successors are duly elected and qualified, as the case may be.

SECTION 2.01. Conversion of Capital Stock. At the Effective Time, by virtue of the Merger and without any action on the part of the holder of any shares of Common Stock, par value $0.01 per share, of the Company (the “Company Common Stock”), or the holder of any shares of capital stock of Sub:

(a) Capital Stock of Sub. Each issued and outstanding share of common stock of Sub shall be converted into and become one fully paid and nonassessable share of common stock, par value $0.01 per share, of the Surviving Corporation.

(b) Cancelation of Treasury Stock and Parent-Owned Stock. All shares of Company Common Stock that are owned as treasury stock by the Company or owned by Parent or Sub immediately prior to the Effective Time shall automatically be canceled and shall cease to exist, and no consideration shall be delivered or deliverable in exchange therefor.

(c) Conversion of Company Common Stock. Each share of Company Common Stock issued and outstanding immediately prior to the Effective Time (other than shares to be canceled in accordance with Section 2.01(b)) shall be converted into the right to receive $46.00 in cash, without interest (the “Merger Consideration”). At the Effective Time such shares shall no longer be outstanding and shall automatically be canceled and shall cease to exist, and each holder of a certificate or evidence of shares in book-entry form that immediately prior to the Effective Time represented any such shares (a “Certificate”) shall cease to have any rights with respect thereto, except the right to receive the Merger Consideration in accordance with

the terms of this Agreement. The right of any holder of any share of Company Common Stock to receive the Merger Consideration shall be subject to and reduced by the amount of any withholding that is required under applicable tax Law, such withholding to be pursuant to the terms of Section 2.02(f) and any applicable tax Law.

SECTION 2.02. Exchange of Certificates. (a)Paying Agent. Prior to the Effective Time, Parent shall designate a bank or trust company reasonably acceptable to the Company to act as agent for the payment of the Merger Consideration upon surrender of Certificates (the “Paying Agent”), and, from time to time after the Effective Time, Parent shall make available, or cause the Surviving Corporation to make available, to the Paying Agent funds in amounts and at the times necessary for the payment of the Merger Consideration pursuant to Section 2.01(c) upon surrender of Certificates, it being understood that all such funds shall be invested as directed by Parent and that any and all interest or other amounts earned with respect to funds made available to the Paying Agent pursuant to this Agreement shall be turned over to Parent.

(b) Exchange Procedure. As soon as reasonably practicable after the Effective Time, the Surviving Corporation or Parent shall cause the Paying Agent to mail to each holder of record of a Certificate (i) a form of letter of transmittal (which shall include an accompanying substitute IRS Form W-9 or the applicable IRS Form W-8, shall specify that delivery shall be effected, and risk of loss and title to the Certificates held by such person shall pass, only upon proper delivery of the Certificates to the Paying Agent and shall be in a form and have such other provisions (including customary provisions regarding delivery of an “agent’s message” with respect to shares held in book-entry form) as Parent may reasonably specify) and (ii) instructions for use in effecting the surrender of the Certificates in exchange for the Merger Consideration. Upon surrender of a Certificate for cancelation to the Paying Agent or to such other agent or agents as may be appointed by Parent, together with such letter of transmittal, duly completed and validly executed, and such other documents as may reasonably be required by the Paying Agent, the holder of such Certificate shall be entitled to receive in exchange therefor the amount of cash equal to the Merger Consideration that such holder has the right to receive pursuant to Section 2.01(c), and the Certificate so surrendered shall forthwith be canceled. In the event of a transfer of ownership of Company Common Stock that is not registered in the stock transfer books of the Company, payment of the Merger Consideration in exchange therefor may be made to a person other than the person in whose name the Certificate so surrendered is registered if such Certificate shall be properly endorsed or otherwise be in proper form for transfer and the person requesting such payment shall pay any transfer or other taxes required by reason of the payment to a person other than the registered holder of such Certificate or establish to the satisfaction of the Surviving Corporation that such tax has been paid or is not applicable. No interest shall be paid or shall accrue on the cash payable upon surrender of any Certificate.

(c) No Further Ownership Rights in Company Common Stock. All Merger Consideration paid upon the surrender of a Certificate in accordance with the terms of this Article II shall be deemed to have been paid in full satisfaction of all rights pertaining to the shares of Company Common Stock formerly represented by such Certificate. At the close of business on the day on which the Effective Time occurs, the stock transfer books of the Company shall be closed, and there shall be no further registration of transfers on the stock transfer books of the Surviving Corporation of the shares that were outstanding immediately prior to the Effective Time. If, after the close of business on the day on which the Effective Time occurs, Certificates are presented to the Surviving Corporation or the Paying Agent for transfer or any other reason, they shall be canceled and exchanged as provided in this Article II.

(d) No Liability. None of Parent, Sub, the Company, the Surviving Corporation or the Paying Agent shall be liable to any person in respect of any Merger Consideration that would otherwise have been payable in respect of any Certificate which is delivered to a public official in accordance with any applicable abandoned property, escheat or similar Law. If any Certificates shall not have been surrendered prior to two years after the Effective Time (or immediately prior to such earlier date on which any Merger Consideration would otherwise escheat to or become the property of any Governmental Entity), any Merger Consideration payable in accordance with this Article II in respect thereof shall, to the extent permitted by applicable Law, become the property of the Surviving Corporation, free and clear of all claims or interest of any person previously entitled thereto.

(e) Lost Certificates. If any Certificate shall have been lost, stolen, defaced or destroyed, upon the making of an affidavit of that fact by the person claiming such Certificate to be lost, stolen, defaced or destroyed and, if required by the Surviving Corporation, the posting by such person of a bond in such amount as the Surviving Corporation may direct as indemnity against any claim that may be made against it with respect to such Certificate, the Paying Agent or the Surviving Corporation, as the case may be, shall pay the Merger Consideration in respect of such lost, stolen, defaced or destroyed Certificate.

(f) Withholding Rights. Parent, the Surviving Corporation or the Paying Agent shall be entitled to deduct and withhold from the Merger Consideration and any other amounts otherwise payable pursuant to this Agreement to any holder of shares of Company Common Stock, Stock Options, Restricted Shares or RSUs such amounts as Parent, the Surviving Corporation or the Paying Agent is required to deduct and withhold with respect to the making of such payment under the Internal Revenue Code of 1986, as amended (the “Code”), or any provision of state, local or foreign tax Law. To the extent that amounts are so withheld and paid over to the appropriate taxing authority by Parent, the Surviving Corporation or the Paying Agent, such withheld amounts shall be treated for all purposes of this Agreement as having been paid to the holder of the shares of Company Common Stock, Stock Options, Restricted Shares or RSUs in respect of which such deduction and withholding was made by Parent, the Surviving Corporation or the Paying Agent.

(g) Termination of Fund. At any time following the six-month anniversary of the Closing Date, the Surviving Corporation shall be entitled to require the Paying Agent to deliver to it any funds (including any interest received with respect thereto) that had been made available to the Paying Agent pursuant to Section 2.02(a) and that have not been disbursed to holders of Certificates, and thereafter, subject to time limitations in Section 2.02(d), such holders shall be entitled to look only to Parent and the Surviving Corporation (subject to abandoned property, escheat or other similar Laws) as general creditors thereof with respect to the payment of any Merger Consideration that may be payable upon surrender of any Certificates held by such holders, as determined pursuant to this Agreement, without any interest thereon.

SECTION 3.01. Representations and Warranties of the Company. Except as set forth in the letter (with specific reference to the Section of this Agreement to which the information stated in such disclosure relates; provided, that disclosure contained in any section of the Company Letter shall be deemed to be disclosed with respect to any other Section of this Agreement to the extent that it is readily apparent from the face of such disclosure that such disclosure is applicable to such other Section of this Agreement) delivered by the Company to Parent prior to the execution of this Agreement (the “Company Letter”), the Company represents and warrants to Parent and Sub as follows:

(a) Organization, Standing and Corporate Power. Each of the Company and its Subsidiaries (i) is a corporation or other legal entity duly organized, validly existing and in good standing under the Laws of the jurisdiction of its organization (except, in the case of good standing, for entities organized under the Laws of any jurisdiction that does not recognize such concept), (ii) has all requisite corporate, company, partnership or other organizational power and authority to carry on its business as currently conducted and (iii) is duly qualified or licensed to do business and is in good standing in each jurisdiction (except, in the case of good standing, any jurisdiction that does not recognize such concept) in which the nature of its business or the ownership, leasing or operation of its properties makes such qualification or licensing necessary, other than where the failure to be so organized, existing, qualified or licensed or in good standing (except, in the case of clause (i) above, with respect to the Company), individually or in the aggregate, is not reasonably likely to have a Material Adverse Effect. The Company has made available to Parent complete and correct copies of the articles of incorporation of the Company, as amended to the date of this Agreement (the “Company Articles”), and the bylaws of the Company, as amended to the date of this Agreement (the “Company

Bylaws”), and the articles of incorporation and bylaws (or similar organizational documents) of each of its Subsidiaries, in each case as amended to the date of this Agreement. The Company has made available to Parent complete and correct copies of the minutes (or, in the case of draft minutes, the most recent drafts thereof) of all meetings of the shareholders, the Board of Directors and each committee of the Board of Directors of the Company and each of its Subsidiaries held since January 1, 2009 (other than portions of any minutes (or drafts thereof) related to the transactions contemplated by this Agreement or any Takeover Proposal). The Company has made available to Parent complete and correct copies of all resolutions of the Board of Directors of the Company, and each committee thereof, in respect of this Agreement and the transactions contemplated hereby.

(b) Subsidiaries. Section 3.01(b) of the Company Letter sets forth a complete and correct list of each Subsidiary of the Company, its place and form of organization, its address and each jurisdiction in which it is authorized to conduct or actually conducts business. All the outstanding shares of capital stock of, or other equity or voting interests in, each such Subsidiary are owned by the Company, by one or more wholly owned Subsidiaries of the Company or by the Company and one or more wholly owned Subsidiaries of the Company, free and clear of all pledges, claims, liens, charges, options, security interests or other encumbrances of any kind or nature whatsoever (collectively, “Liens”), except for transfer restrictions imposed by applicable securities Laws, and are duly authorized, validly issued, fully paid and nonassessable. Except for the capital stock of, or other equity or voting interests in, its Subsidiaries, the Company does not own, directly or indirectly, any capital stock of, or other equity or voting interests in, any person.

(c) Capital Structure. (i) The authorized capital stock of the Company consists of 100,000,000 shares of Company Common Stock and 10,000,000 shares of Preferred Stock, par value $0.01 per share, of the Company (the “Company Preferred Stock”). At the close of business on August 23, 2012, (A) 27,549,970 shares of Company Common Stock (excluding treasury shares) were issued and outstanding, 6,036 of which were subject to vesting or transfer restrictions and/or subject to forfeiture back to the Company or repurchase by the Company, whether granted pursuant to the Amended and Restated 2005 Equity Incentive Plan (the “Amended 2005 Plan”) or otherwise (such shares, together with any shares granted after August 23, 2012 that are so subject, the “Restricted Shares”), (B) 0 shares of Company Common Stock were held by the Company as treasury shares, (C) 4,978,897 shares of Company Common Stock were reserved and available for issuance in the aggregate pursuant to the Amended 2005 Plan, the 2000 Stock Option Plan (the “2000 Plan”) and the 2006 Employee Stock Purchase Plan (the “ESPP”, and together with the Amended 2005 Plan and the 2000 Plan, the “Company Stock Plans”), of which (x) 2,556,236 shares of Company Common Stock were subject to outstanding options (other than rights under the ESPP) to acquire shares of Company Common Stock from the Company (such options, together with any other stock options granted after August 23, 2012, in each case whether granted pursuant to the Company Stock Plans or otherwise, the “Stock Options”), (y) 6,036 were Restricted Shares and (z) a maximum of 267,044 shares of Company Common Stock were subject to outstanding restricted stock units (such restricted stock units, together with any other restricted stock units granted after August 23, 2012, in each case whether granted pursuant to the Company Stock Plans or otherwise, the “RSUs”), of which 267,044 shares of Company Common Stock were subject to RSUs with service-based, but not performance-based, vesting or delivery requirements and (D) 351,311 shares of Company Common Stock were reserved and available for issuance pursuant to the ESPP. As of the date of this Agreement, other than the Restricted Shares, none of the issued and outstanding Company Common Stock is subject to vesting or forfeiture conditions or a right of repurchase by the Company. All outstanding Stock Options, Restricted Shares and RSUs have been granted under the Company Stock Plans. Other than the Company Stock Plans, there is no plan, Contract or arrangement providing for the grant of Stock Options, Restricted Shares or RSUs. No shares of Company Preferred Stock are issued or outstanding. No shares of Company Common Stock are owned by any Subsidiary of the Company.

As of the close of business on August 23, 2012, there were outstanding rights to purchase 3,845 shares of Company Common Stock on the last day of the current offering period in effect under the ESPP (assuming the fair market value per share of Company Common Stock on the last day of the current offering period in effect under the ESPP will be equal to the Merger Consideration). As of the last day of the most recent payroll period ending prior to the date of this Agreement, the aggregate amount credited to the accounts of participants in the ESPP was $176,914.14 and the aggregate amount credited to such accounts for such payroll period was $37,822.76.

(ii) Except for outstanding shares of Company Common Stock, Stock Options, Restricted Shares and RSUs set forth in Section 3.01(c)(i), as of the close of business on August 23, 2012, no shares of capital stock of, or other equity or voting interests in, the Company, or securities convertible into, or exchangeable or exercisable for, or options, warrants, shares of deferred stock, restricted stock awards, stock appreciation rights, phantom stock awards or other rights to acquire any such capital stock of, or other equity or voting interests in, the Company, or other rights that are linked to the value of Company Common Stock or the value of the Company or any part thereof, were issued, reserved for issuance or outstanding. From the close of business on August 23, 2012 to the date of this Agreement, (A) there have been no issuances by the Company of shares of capital stock of, or other equity or voting interests in, the Company, other than issuances of shares of Company Common Stock pursuant to the exercise of Stock Options or rights under the ESPP or the settlement of RSUs, in each case outstanding as of August 23, 2012, and only if and to the extent required by their respective terms as in effect on such date and (B) there have been no issuances by the Company of securities convertible into, or exchangeable or exercisable for, or options, warrants, shares of deferred stock, restricted stock awards, stock appreciation rights, phantom stock awards, other rights to acquire shares of capital stock of, or other equity or voting interests in, the Company, or other rights that are linked to the value of Company Common Stock or the value of the Company or any part thereof, other than rights under the ESPP.

(iii) All outstanding shares of capital stock of the Company are, and all shares that may be issued pursuant to the Company Stock Plans will be, when issued in accordance with the terms thereof, duly authorized, validly issued, fully paid and nonassessable and not subject to preemptive rights. Except as set forth in this Section 3.01(c), there are no (A) bonds, debentures, notes or other indebtedness of the Company or any of its Subsidiaries and (B) securities or other instruments or rights (including stock appreciation rights, phantom stock awards or other similar rights) issued by, or other obligations of, the Company or any of its Subsidiaries, in each case, that are linked to, or the value of which is in any way based upon or derived from, the value of any class of capital stock of, or other equity or voting interests in, the Company or any of

its Subsidiaries, the value of the Company, any of its Subsidiaries or any part thereof, or any dividends or other distributions declared or paid on any shares of capital stock of, or other equity or voting interests in, the Company or any of its Subsidiaries, or which have or which by their terms may have at any time (whether actual or contingent) the right to vote (or which are convertible into, or exchangeable for, securities having the right to vote) on any matters on which shareholders of the Company or any of its Subsidiaries may vote (the items referred to in clauses (A) and (B) collectively, “Equity Equivalents”). Except as set forth in this Section 3.01(c), there are no securities, options, warrants, calls, rights or Contracts of any kind to which the Company or any of its Subsidiaries is a party, or by which the Company or any of its Subsidiaries is bound, obligating the Company or any of its Subsidiaries to issue, deliver or sell, or cause to be issued, delivered or sold, additional shares of capital stock of, or other equity or voting interests in, or securities convertible into, or exchangeable or exercisable for, shares of capital stock of, or other equity or voting interests in, the Company or any of its Subsidiaries or obligating the Company or any of its Subsidiaries to issue, grant, extend or enter into any such security, option, warrant, call, right or Contract. With respect to the Stock Options, (1) each Stock Option intended to qualify as an “incentive stock option” under Section 422 of the Code so qualifies, (2) each grant of a Stock Option was duly authorized no later than the date on which the grant of such Stock Option was by its terms to be effective (the “Grant Date”) by all necessary corporate action, including, as applicable, approval by the Board of Directors of the Company (or a duly constituted and authorized committee thereof) and any required shareholder approval by the necessary number of votes or written consents, and the award agreement governing such grant (if any) was duly executed and delivered by each party thereto, (3) each such grant was made in accordance with the terms of the applicable Company Stock Plan, the Exchange Act and all other applicable Laws and regulatory rules or requirements, including the rules of The NASDAQ Stock Market LLC and The New York Stock Exchange, as applicable, and any other exchange on which Company securities are traded, (4) the per share exercise price of each Stock Option was not less than the fair market value (within the meaning of Section 422 of the Code, in the case of each Stock Option intended to qualify as an “incentive stock option” and within the meaning of Section 409A of the Code, in the case of each other Stock Option) of a share of Company Common Stock on the applicable Grant Date and (5) each such grant was properly accounted for in accordance with GAAP in the financial statements (including the related notes) of the Company and disclosed in the Company’s SEC Documents in accordance with the Exchange Act and all other applicable Laws. The ESPP qualifies as an “employee stock purchase plan” within the meaning of Section 423(b) of the Code and Treasury Regulation Section 1.423-2. Each election pursuant to Section 83(b) of the Code that has been made with respect to a Restricted Share has been validly made in accordance with Section 83(b) of the Code and the Treasury Regulations thereunder, including with respect to correctly reporting the fair market value of such Restricted Share on the applicable Section 83(b) election form. Except pursuant to the forfeiture conditions of the Stock Options, Restricted Shares and RSUs outstanding as of the date of this Agreement and except pursuant to the cashless exercise or tax withholding provisions of such Stock Options, Restricted Shares and RSUs, in each case as in effect on the date of this Agreement, there are no outstanding contractual or other obligations of the Company or any of its Subsidiaries to (I) repurchase, redeem or otherwise acquire any shares of capital stock of, or other equity or voting interests in, the Company or any of its Subsidiaries or (II) vote or dispose of any shares of capital stock of, or other equity or voting interests in, the Company or any of its Subsidiaries.

(v) All Stock Options, Restricted Shares and RSUs may, by their terms, be treated in accordance with Section 5.04(a), and all rights to purchase shares of Company Common Stock under the ESPP may, by their terms, be treated in accordance with Section 5.04(b). No holder of any Stock Option, Restricted Share, RSU or right under the ESPP is entitled to any treatment of such Stock Option, Restricted Share, RSU or right under the ESPP other than as provided with respect to such Stock Option, Restricted Share, RSU or right under the ESPP in Section 5.04(a) or Section 5.04(b), as applicable, and after the Closing no holder of a Stock Option, Restricted Share, RSU or right under the ESPP (or former holder of a Stock Option, Restricted Share, RSU or right under the ESPP) or any current or former participant in the Company Stock Plans or any other Benefit Plan or Benefit Agreement shall have the right thereunder to acquire any capital stock of the Company or any other equity interest therein (including phantom stock or stock appreciation rights).

The execution and delivery of this Agreement, the consummation of the Merger and the other transactions contemplated by this Agreement (alone or in combination with any other event, including any termination of employment on or following the Closing) and compliance by the Company with the provisions of this Agreement do not and will not (1) trigger any funding (through a grantor trust or otherwise) of, or increase the cost of, or give rise to any other obligation under, any Benefit Plan, Benefit Agreement or any other employment arrangement, (2) trigger the forgiveness of indebtedness owed by any Company Personnel to the Company or any of its affiliates or (3) result in any violation or breach of, or a default (with or

without notice or lapse of time or both) under, or limit to the Company’s or any of its Subsidiaries’ ability to amend, modify or terminate, any Benefit Plan or Benefit Agreement.

Neither the Company nor any of its Subsidiaries has received notice of any, and, to the knowledge of the Company, there are no, pending investigations by any Governmental Entity with respect to, or pending termination proceedings or other material claims (except claims for benefits payable in the normal operation of the Benefit Plans and Benefit Agreements), suits or proceedings against or involving or asserting any rights or claims to benefits under, any Benefit Plan or Benefit Agreement.

(viii) All contributions, premiums and benefit payments under or in connection with each Benefit Plan and Benefit Agreement that are required to have been made by the Company or any of its Subsidiaries in accordance with the terms of such Benefit Plan and Benefit Agreement and applicable Laws have been timely made.

Neither the Company nor any of its Subsidiaries has incurred, or could reasonably be expected to incur, any unfunded liabilities in relation to any Benefit Plan or Benefit Agreement.

(ix) With respect to each Benefit Plan, (A) there has not occurred any prohibited transaction in which the Company, any of its Subsidiaries or any of their respective directors, officers or employees or, to the knowledge of the Company, any trustee, administrator or other fiduciary of such Benefit Plan or trust created thereunder, in each case, who is not a director, officer or employee of the Company or any of its Subsidiaries (a “Non-Affiliate Plan Fiduciary”), has engaged that could subject the Company, any of its Subsidiaries or any of their respective directors, officers or employees or any Non-Affiliate Plan Fiduciary to the tax or penalty on prohibited transactions imposed by Section 4975 of the Code or the sanctions imposed under Title I of ERISA or any other applicable Law and (B) none of the Company, any of its Subsidiaries or any of their respective directors, officers or employees or, to the knowledge of the Company, any Non-Affiliate Plan Fiduciary, or any agent of any of the foregoing, has engaged in any transaction or acted in a manner, or failed to act in a manner, that could subject the Company, any of its Subsidiaries or any of their respective directors, officers or employees or any Non-Affiliate Plan Fiduciary to any liability for breach of fiduciary duty under ERISA or any other applicable Law. No Benefit Plan or related trust has been terminated, nor has there been any “reportable event” (as such term is defined in Section 4043 of ERISA) for which the 30-day reporting requirement has not been waived with respect to any Benefit Plan during the last five years, and no notice of a reportable event will be required to be filed in connection with the Merger or the other transactions contemplated by this Agreement.

For purposes of this Agreement, the term “Superior Proposal” means any binding bona fide unsolicited written offer which did not result from a breach of Section 4.02(a) made by any person (other than Parent or Sub or any of their affiliates) that, if consummated, would result in such person (or, in the case of a direct merger between such person and the Company, the shareholders of such person) acquiring, directly or indirectly, more than 50% of the voting power of the Company Common Stock or all or substantially all the assets of the Company and its Subsidiaries, taken as a whole, and which offer, in the reasonable good faith judgment of the Board of Directors of the Company (after consultation with a financial advisor of nationally recognized reputation and outside legal counsel), (x) provides a higher value to the shareholders of the Company than the consideration payable in the Merger (taking into account all of the terms and conditions of such proposal and this Agreement (including any changes to the terms of this Agreement proposed by Parent in response to such Superior Proposal or otherwise)), (y) is not subject to any financing condition or contingency and (z) is reasonably capable of being completed, taking into account all financial, legal, regulatory and other aspects of such proposal.

(b) Neither the Board of Directors of the Company nor any committee thereof shall (or shall agree or resolve to) (i) withdraw or modify in a manner adverse to Parent or Sub, or propose publicly to withdraw or modify in a manner adverse to Parent or Sub, the recommendation or declaration of advisability by such Board of Directors or any such committee of this Agreement or the Merger (any such action, resolution or agreement to take such action being referred to herein as an “Adverse Recommendation Change”), (ii) recommend, declare advisable or propose to recommend or declare advisable, the approval or adoption of any Takeover Proposal or resolve or agree to take any such action, or adopt or approve any Takeover Proposal, or (iii) cause or permit the Company to enter into any letter of intent, memorandum of understanding, agreement in principle, acquisition agreement, merger agreement, option agreement, joint venture agreement, partnership agreement or other agreement (each, an “Acquisition Agreement”) constituting or related to, or which is intended to or is reasonably likely to lead to, any Takeover Proposal (other than a confidentiality agreement referred to in Section 4.02(a)), or resolve or agree to take any such action. Notwithstanding the foregoing, at any time prior to the Shareholder Approval, the Board of Directors of the Company may, in response to a Superior Proposal, effect an Adverse Recommendation Change; provided that the Board of Directors of the Company determines in good faith, after consultation with its outside legal counsel and a financial advisor of nationally recognized reputation, that the failure to do so would be inconsistent with its fiduciary duties under applicable Law; and provided further, that the Board of Directors of the Company may not effect such an Adverse Recommendation Change unless (A) the Board of Directors of the Company shall have first provided prior written notice to Parent (an “Adverse Recommendation Change Notice”) that it is prepared to effect an Adverse Recommendation Change in response to a Superior Proposal, which notice shall attach the most current version of any written agreement relating to the transaction that constitutes such Superior Proposal, and (B) Parent does not make, within five business days after the receipt of such notice, a proposal that would, in the reasonable good faith judgment of the Board of Directors of the Company (after consultation with a financial advisor of national reputation and outside legal counsel), cause the offer previously constituting a Superior Proposal to no longer constitute a Superior Proposal (it being understood and agreed that any amendment or modification of such Superior Proposal shall require a new Adverse Recommendation Change Notice and a new five business day period). The Company agrees that, during the five business day period prior to its effecting an Adverse Recommendation Change, the Company and its officers, directors and representatives shall negotiate in good faith with Parent and its officers, directors and representatives regarding any revisions to the terms of the Merger and the other transactions contemplated by this Agreement proposed by Parent.

(c) In addition to the obligations of the Company set forth in paragraphs (a) and (b) of this Section 4.02, the Company shall, as promptly as possible and in any event within 24 hours after the receipt thereof, advise Parent orally and in writing of (i) any Takeover Proposal or any request for information or inquiry that the Company reasonably believes could lead to or contemplates a Takeover Proposal and (ii) the terms and conditions of such Takeover Proposal, request or inquiry (including any subsequent amendment or other modification to such terms and conditions) and the identity of the person making any such Takeover Proposal, request or inquiry. Commencing upon the provision of any notice referred to above, the Company (or its outside counsel) shall (A) on a daily basis at mutually agreeable times, advise and confer with Parent (or its outside counsel) regarding the progress of negotiations concerning any Takeover Proposal, the material resolved and unresolved issues related thereto and any other matters identified with reasonable specificity by Parent (or its outside counsel) and the material details (including material amendments or proposed amendments as to price and other material terms) of any such Takeover Proposal, request or inquiry and (B) promptly upon receipt or delivery thereof, provide Parent (or its outside counsel) with copies of all documents and written or electronic communications relating to any such Takeover Proposal (including the financing thereof), request or inquiry exchanged between the Company, its Subsidiaries or any of their respective officers, directors, employees, investment bankers, attorneys, accountants or other advisors or representatives, on the one hand, and the person making a Takeover Proposal or any of its affiliates, or their respective officers, directors, employees, investment bankers, attorneys, accountants or other advisors or representatives, on the other hand; provided that in the case of subclause (A) above only, in connection with any Superior Proposal with respect to which (1) the Board of Directors of the Company has effected an Adverse Recommendation Change in accordance with this Section 4.02 and (2) Parent did not make, within five business days after the receipt of the related Adverse Recommendation Change Notice, a proposal that would, in the

reasonable good faith judgment of the Board of Directors of the Company (after consultation with a financial advisor of national reputation and outside legal counsel), cause the offer previously constituting such Superior Proposal to no longer constitute a Superior Proposal, the Company (and its outside counsel) shall only be required to so advise and confer at times reasonably requested by Parent (rather than on a daily basis).

(d) Nothing contained in this Section 4.02 or elsewhere in this Agreement shall prohibit the Company from (i) taking and disclosing to its shareholders a position contemplated by Rule 14d-9 and Rule 14e-2(a) promulgated under the Exchange Act or (ii) making any disclosure to its shareholders if, in the good faith judgment of the Board of Directors of the Company, failure so to disclose would be inconsistent with applicable Law; provided, however, that in no event shall the Company or its Board of Directors or any committee thereof take, agree or resolve to take any action prohibited by Section 4.02(b).

SECTION 4.03. Conduct by Parent. During the period from the date of this Agreement to the Effective Time, except as consented to in writing by the Company prior to such action or as specifically contemplated by this Agreement, Parent shall not, and shall not permit any of its Subsidiaries to, take any action that could reasonably be expected to result in (a) any representation and warranty of Parent or Sub set forth in this Agreement that is qualified as to materiality becoming untrue (as so qualified) or (b) any such representation and warranty that is not so qualified becoming untrue in any material respect.

SECTION 5.01. Preparation of the Proxy Statement; Shareholders Meeting. (a)As promptly as practicable following the date of this Agreement, the Company shall prepare and file with the SEC the preliminary Proxy Statement. Each of the Company and Parent shall furnish all information concerning such person to the other as may be reasonably requested in connection with the preparation, filing and distribution of the Proxy Statement. The Company shall promptly notify Parent upon the receipt of any comments from the SEC or its staff or any request from the SEC or its staff for amendments or supplements to the Proxy Statement and shall provide Parent with copies of all correspondence between it and its representatives, on the one hand, and the SEC, on the other hand. Each of the Company and Parent shall use commercially reasonable efforts to respond as promptly as practicable to any comments of the SEC with respect to the Proxy Statement. Notwithstanding the foregoing, prior to filing or mailing the Proxy Statement (or any amendment or supplement thereto) or responding to any comments of the SEC with respect thereto, the Company (i) shall provide Parent an opportunity to review and comment on such document or response, (ii) shall include in such document or response all comments reasonably proposed by Parent and (iii) shall not file or mail such document, or respond to the SEC, prior to receiving the approval of Parent, which approval shall not be unreasonably withheld or delayed. If, at any time prior to the Shareholders Meeting, any information relating to the Company, Parent or any of their respective affiliates, officers or directors should be discovered by the Company or Parent which should be set forth in an amendment or supplement to the Proxy Statement, so that the Proxy Statement shall not contain any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary in order to make the statements therein, in light of the circumstances under which they are made, not misleading, the party that discovers such information shall promptly notify the other parties hereto, and an appropriate amendment or supplement describing such information shall be filed with the SEC and, to the extent required by applicable Law, disseminated to the shareholders of the Company.

(b) The Company agrees that the Proxy Statement will comply as to form in all material respects with the requirements of the Exchange Act and that none of the information included or incorporated by reference in the Proxy Statement will, at the date the Proxy Statement is filed with the SEC or mailed to the shareholders of the Company or at the time of the Shareholders Meeting, or at the time of any amendment or supplement thereof, contain any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary in order to make the statements therein, in light of the circumstances under which they are made, not

misleading, except that no covenant is made by the Company with respect to statements made in the Proxy Statement based on information supplied in writing by or on behalf of Parent specifically for inclusion or incorporation for reference therein. Parent agrees that none of such information will, at the date the Proxy Statement is filed with the SEC or mailed to the shareholders of the Company or at the time of the Shareholders Meeting, or at the time of any amendment or supplement thereof, contain any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary in order to make the statements therein, in light of the circumstances under which they are made, not misleading.

(c) Each of the Company and Parent shall use reasonable best efforts to cause the mailing of the Proxy Statement to the shareholders of the Company to occur during the week beginning October 22, 2012. The Company shall, as promptly as practicable after the filing of the preliminary Proxy Statement with the SEC, establish a record date (which will be as promptly as reasonably practicable following the date of this Agreement) for, duly call, give notice of, convene and hold a meeting of its shareholders (the “Shareholders Meeting”), which meeting the Company shall, absent any Legal Restraint that has the effect of preventing such action, cause to occur on the date that is 35 calendar days immediately following the date of mailing of the Proxy Statement, for the purpose of obtaining the Shareholder Approval, regardless of whether the Board of Directors of the Company determines at any time that this Agreement is no longer advisable or recommends that the shareholders of the Company reject it or any other Adverse Recommendation Change has occurred at any time; provided, however, that (i) if the Company is unable to obtain a quorum of its shareholders at such time, the Company may extend the date of the Shareholders Meeting to the extent (and only to the extent) necessary in order to obtain a quorum of its shareholders and the Company shall use its commercially reasonable efforts to obtain such a quorum as promptly as practicable, (ii) the Company may delay the Shareholders Meeting to the extent (and only to the extent) the Company reasonably determines that such delay is required by applicable Law to comply with comments made by the SEC with respect to the Proxy Statement and (iii) the Company may delay the Shareholders Meeting to the extent (and only to the extent) required by a court of competent jurisdiction in connection with any proceedings in connection with this Agreement, the Merger or the other transactions contemplated by this Agreement. The notice of such Shareholders Meeting shall state that a resolution to adopt this Agreement will be considered at the Shareholders Meeting. Subject to Section 4.02(b), (A) the Board of Directors of the Company shall recommend to holders of Company Common Stock that they adopt this Agreement and shall include such recommendation in the Proxy Statement and (B) the Company shall use its commercially reasonable efforts to solicit the Shareholders Approval. Without limiting the generality of the foregoing, the Company agrees that its obligations pursuant to this Section 5.01(c) shall not be affected by the commencement, public proposal, public disclosure or communication to the Company or any other person of any Takeover Proposal. The Company shall provide updates to Parent with respect to the proxy solicitation for the Shareholders Meeting (including interim results) as reasonably requested by Parent.

SECTION 5.02. Access to Information; Confidentiality. (a) The Company shall, and shall cause each of its Subsidiaries to, afford to Parent and to Parent’s officers, employees, investment bankers, attorneys, accountants, consultants and other representatives and advisors full access upon reasonable advance notice and during normal business hours during the period prior to the Effective Time or the termination of this Agreement to all their respective properties, assets, books, records, Contracts, Permits, documents, information, directors, officers and employees, and during such period the Company shall, and shall cause each of its Subsidiaries to, furnish to Parent any information concerning its business as Parent may reasonably request (including, to the extent the Company is able, the work papers of Grant Thornton LLP). Following the date of this Agreement and prior to the Effective Time, Parent may (but shall not be required to), following reasonable notice to the Company, contact and interview any Company Personnel and review the personnel records and such other information concerning the Company Personnel as Parent may reasonably request. No investigation by Parent or any of its officers, directors, employees, investment bankers, attorneys, accountants or other advisors or representatives and no other receipt of information by Parent or any of its officers, directors, employees, investment bankers, attorneys, accountants or other advisors or representatives shall operate as a waiver or otherwise affect any representation, warranty, covenant, agreement or other provision of this Agreement, or the obligations of the parties (or remedies with respect thereto) or the conditions to the obligations of the parties under the Agreement. Except as required by any applicable Law or

Judgment, Parent will hold, and will direct its officers, employees, investment bankers, attorneys, accountants and other advisors and representatives to hold, any and all information received from the Company confidential in accordance with the Confidentiality Agreement.

(b) Without limiting the generality of the foregoing, during the period from the date of this Agreement to the Effective Time, the Company shall, and shall cause each of its Subsidiaries to, as and to the extent requested by Parent, provide Parent with (i) a complete and correct list of all licenses issued by the Federal Communications Commission (the “FCC”) and held by the Company or any of its Subsidiaries (the “FCC Licenses”), (ii) complete and correct copies of each FCC License, (iii) the address and physical location of the device(s) covered by each FCC License, (iv) a written description of the purpose of the device(s) covered by each FCC License, (v) complete and correct copies of any Notices of Apparent Liability for Forfeiture issued by the FCC against the Company or any of its Subsidiaries and (vi) all information reasonably necessary for Parent to make an independent determination that the Company and its Subsidiaries have complied with FCC rules regarding changes of ownership control of the FCC Licenses (including descriptions of any transactions that effected a change of ownership or control of the FCC Licenses (including any intracompany reorganizations) and corporate organizational charts depicting the ownership structure of the holder of the FCC Licenses before and after any such change of ownership or control).

(c) Subject to applicable law, the Company and Parent shall, and shall cause each of their respective Subsidiaries to, cooperate to ensure an orderly transition and integration process in connection with the Merger and the other transactions contemplated by this Agreement in order to minimize the disruption to, and preserve the value of, the business of the Surviving Corporation and its Subsidiaries.

SECTION 5.03. Commercially Reasonable Efforts; Consultation and Notice. (a) Upon the terms and subject to the conditions set forth in this Agreement, each of the parties hereto agrees to use its commercially reasonable efforts to take, or cause to be taken, all actions that are necessary, proper or advisable to consummate and make effective the Merger and the other transactions contemplated by this Agreement (including transactions under the Shareholder Agreements), including using its commercially reasonable efforts to accomplish the following: (i) the satisfaction of the conditions precedent set forth in Article VI, (ii) the obtaining of all necessary actions or nonactions, waivers, consents, approvals, orders and authorizations from, and the giving of any necessary notices to, Governmental Entities and other persons and the making of all necessary registrations, declarations and filings (including filings under the HSR Act and other registrations, declarations and filings with, or notices to, Governmental Entities, if any), (iii) the taking of all reasonable steps to provide any supplemental information requested by a Governmental Entity, including participating in meetings with officials of such entity in the course of its review of this Agreement, the Merger or the other transactions contemplated by this Agreement, (iv) the taking of all reasonable steps as may be necessary to avoid any suit, claim, action, investigation or proceeding by any Governmental Entity or third party and (v) the obtaining of all necessary consents, approvals or waivers from any third party. In connection with and without limiting the generality of the foregoing, each of the Company and its Board of Directors shall, if any state takeover statute or similar statute or regulation, including the Pennsylvania Takeover Disclosure Law or Subchapters E, G, H, I or J of Chapter 25 of the PBCL, is or becomes applicable to this Agreement, the Shareholder Agreements or any of the Merger and the other transactions contemplated by this Agreement, including transactions under the Shareholder Agreements, take all actions necessary to ensure that the Merger and the other transactions contemplated by this Agreement, including transactions under the Shareholder Agreements, may be consummated as promptly as practicable on the terms contemplated by this Agreement and otherwise to minimize the effect of such statute or regulation on this Agreement, the Shareholder Agreements, the Merger and the other transactions contemplated by this Agreement, including transactions under the Shareholder Agreements. Notwithstanding the foregoing or any other provision of this Agreement to the contrary, in no event shall Parent or Sub be obligated to, and the Company and its Subsidiaries shall not without the prior written consent of Parent, agree or proffer to divest or hold separate, or enter into any licensing, business restriction or similar arrangement with respect to, any assets (whether tangible or intangible) or any portion of any business of Parent, the Company or any of their respective Subsidiaries. Notwithstanding the foregoing or any other provision of this Agreement to the contrary, in no event shall Parent or any of its Subsidiaries be obligated to litigate or participate in the litigation of any suit, claim, action,

investigation or proceeding, whether judicial or administrative, brought by any Governmental Entity (A) challenging or seeking to restrain or prohibit the consummation of the Merger or the other transactions contemplated by this Agreement, including transactions under the Shareholder Agreements, or seeking to obtain from Parent or any of its Subsidiaries any damages in relation therewith; (B) seeking to prohibit or limit in any respect, or place any conditions on, the ownership or operation by the Company, Parent or any of their respective affiliates of all or any portion of the business or assets or any product of the Company or its Subsidiaries or Parent or its Subsidiaries or to require any such person to dispose of, license (whether pursuant to an exclusive or nonexclusive license) or hold separate all or any portion of the business or assets or any product of the Company or its Subsidiaries or Parent or its Subsidiaries, in each case as a result of or in connection with the Merger or any of the other transactions contemplated by this Agreement; (C) seeking to directly or indirectly impose limitations on the ability of Parent or any of its affiliates to acquire or hold, or exercise full rights of ownership of, any shares of Company Common Stock or any shares of common stock of the Surviving Corporation or any of Parent’s Subsidiaries, including the right to vote Company Common Stock or the shares of common stock of the Surviving Corporation or any of Parent’s Subsidiaries on all matters properly presented to the shareholders of the Company, the Surviving Corporation or any of Parent’s Subsidiaries, respectively; or (D) seeking to (1) directly or indirectly prohibit Parent or any of its affiliates from effectively controlling in any respect any of the business or operations of the Company or its or Parent’s Subsidiaries or (2) directly or indirectly prevent the Company or its or Parent’s Subsidiaries from operating any of their respective businesses in substantially the same manner as operated by the Company and its or Parent’s Subsidiaries immediately prior to the date of this Agreement. The Company and Parent shall provide such assistance, information and cooperation to each other as is reasonably required to obtain any such actions, nonactions, waivers, consents, approvals, orders and authorizations and, in connection therewith, shall notify the other person promptly following the receipt of any comments from any Governmental Entity and of any request by any Governmental Entity for amendments, supplements or additional information in respect of any registration, declaration or filing with, or notice to, such Governmental Entity.

(b) (i) In connection with the continuing operation of the business of the Company and its Subsidiaries between the date of this Agreement and the Effective Time, subject to applicable Law, the Company shall consult in good faith on a reasonably regular basis with Parent to report material, individually or in the aggregate, operational developments, the general status of relationships with customers and resellers, the general status of ongoing operations and other matters reasonably requested by Parent pursuant to procedures reasonably requested by Parent; provided, however, that no such consultation shall operate as a waiver or otherwise affect any representation, warranty, covenant, agreement or other provision in this Agreement, or the obligations of the parties (or remedies with respect thereto) or the conditions to the obligations of the parties under this Agreement.

(ii) Except as prohibited by applicable Law, the Company shall, promptly upon having knowledge, notify Parent in writing of:

(A) the occurrence of any matter or event that (1) is, or that could reasonably be expected to be, material (individually or in the aggregate) to the business, assets, properties, condition (financial or otherwise) or results of operations of the Company and its Subsidiaries, taken as a whole, or (2) has resulted, or could reasonably be expected to result, in (I) any representation and warranty of the Company set forth in this Agreement that is qualified as to materiality becoming untrue, (II) any such representation and warranty that is not so qualified becoming untrue in any material respect or (III) any condition to the transactions contemplated hereby and set forth in Section 6.02 not being satisfied;

(B) the failure of the Company to perform in any material respect any obligation to be performed by it under this Agreement;

(C) any notice or other communication from any person (other than a Governmental Entity) alleging that notice to or consent of such person is required in connection with the Merger or the other transactions contemplated by this Agreement;

(D) any notice or other communication from any customer, distributor or reseller to the effect that such customer, distributor or reseller is terminating or otherwise materially adversely modifying its

relationship with the Company or any of its Subsidiaries as a result of the Merger or the other transactions contemplated by this Agreement;

(E) any material notice or other material communication from any Governmental Entity in connection with the Merger or the other transactions contemplated by this Agreement, and a copy of any such notice or communication shall be furnished to Parent, together with the Company’s written notice;

(F) any filing or notice made by the Company with any Governmental Entity in connection with the Merger or the other transactions contemplated by this Agreement, and a copy of any such filing or notice shall be furnished to Parent together with the Company’s written notice; and

provided, however, that no such notification shall operate as a waiver or otherwise affect any representation, warranty, covenant, agreement or other provision in this Agreement, or the obligations of the parties (or remedies with respect thereto) or the conditions to the obligations of the parties under this Agreement.

(iii) Parent, upon having knowledge, shall give prompt notice to the Company of (A) any representation or warranty made by Parent or Sub contained in this Agreement becoming untrue or inaccurate such that the condition set forth in Section 6.03(a) could not be satisfied or (B) the failure of Parent or Sub to perform in any material respect any obligation to be performed by such party under this Agreement such that the condition set forth in Section 6.03(b) could not be satisfied; provided, however, that no such notification shall affect the representations, warranties, covenants, agreements or obligations of the parties (or remedies with respect thereto) or the conditions to the obligations of the parties under this Agreement.

(c) Without limiting the generality of the foregoing, the Company shall give Parent the opportunity to participate in the defense of any litigation against the Company and/or its directors relating to the Merger or the other transactions contemplated by this Agreement, including transactions under the Shareholder Agreements, and will obtain the prior written consent of Parent prior to settling or satisfying any such claim, it being understood and agreed that this Section 5.03(c) shall not give Parent the right to direct such defense.

(d) Immediately following the execution and delivery of this Agreement by each of the parties hereto, Parent, as the sole shareholder of Sub, will adopt this Agreement.

No consent, approval, order or authorization of, or registration, declaration or filing with, any Governmental Entity or other person (including any spouse) (“Consent”) is required by or with respect to Shareholder in connection with the execution and delivery of this Agreement by Shareholder, the consummation by Shareholder of the transactions contemplated by this Agreement or the

(c) Interpretation. When a reference is made in this Agreement to a Section or a Schedule, such reference shall be to a Section of, or a Schedule to, this Agreement unless otherwise indicated. The headings contained in this Agreement are for reference purposes only and shall not affect in any way the meaning or interpretation of this Agreement. Whenever the words “include”, “includes” or “including” are used in this Agreement, they shall be deemed to be followed by the words “without limitation”. The words “hereof”, “hereto”, “hereby”, “herein” and “hereunder” and words of similar import when used in this Agreement shall refer to this Agreement as a whole and not to any particular provision of this Agreement. The words “date hereof” shall refer to the date of this Agreement. The term “or” is not exclusive.

(g) 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, all other conditions and terms of this Agreement shall nevertheless remain in full force and effect. 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 as closely as possible to the fullest extent permitted by applicable Law in an acceptable manner and to the end that the transactions contemplated hereby are fulfilled to the extent possible.

(h) Consent to Jurisdiction; Service of Process; Venue. Each of the parties hereto irrevocably and unconditionally submits to the exclusive jurisdiction of (a) any New York State court sitting in the County of New York and (b) the United States District Court for the Southern District of New York for the purposes of any suit, action or other proceeding arising out of this Agreement or the Merger or any other transaction contemplated by this Agreement (and agrees that no such action, suit or proceeding relating to this Agreement shall be brought by it or any of its Subsidiaries except in such courts). In the event of an action filed in any New York State court sitting in the County of New York, each party commits to designate such action as appropriate for assignment to the Commercial Division. Each of the parties further agrees that, to the fullest extent permitted by applicable Law, service of any process, summons, notice or document by U.S. registered mail to such person’s respective address set forth above shall be effective service of process for any action, suit or proceeding in the State of New York with respect to any matter to which it has submitted to jurisdiction as set forth above in the immediately preceding sentence. The Shareholder hereby appoints the Company as its agent for service of process for any claim, action, suit or other proceeding in New York with respect to any matters to which it has submitted to jurisdiction as set forth above.

(i) Enforcement. The parties agree that irreparable damage would occur in the event that any of the provisions of this Agreement were not performed in accordance with their specific terms or were otherwise breached. It is accordingly agreed that the parties hereto shall be entitled to an injunction or injunctions to prevent breaches of this Agreement and to enforce specifically the terms and provisions of this Agreement in any New York State court sitting in the County of New York or in the United States District Court for the Southern District of New York, this being in addition to any other remedy to which they are entitled at Law or in equity.

(j) Waiver of Jury Trial. Each party hereto hereby waives, to the fullest extent permitted by applicable Law, any right it may have to a trial by jury in respect of any suit, action or other proceeding directly or indirectly arising out of, under or in connection with this Agreement.

(k) Expenses. All fees, costs and expenses (including all legal, accounting, broker, finder or investment banker fees) incurred in connection with this Agreement and the transactions contemplated hereby are to be paid by the party incurring such fees, costs and expenses.

IN WITNESS WHEREOF, Parent has caused this Agreement to be signed by its officer thereunto duly authorized and Shareholder has signed this Agreement, all as of the date first written above.

We understand that Kenexa Corporation, a Pennsylvania corporation (“Kenexa”), International Business Machines Corporation, a New York corporation (“Buyer”), and Jasmine Acquisition Corp., a Pennsylvania corporation and wholly owned subsidiary of Buyer (“Merger Sub”), propose to enter into an Agreement and Plan of Merger (the “Agreement”), pursuant to which Buyer will acquire Kenexa (the “Transaction”). Pursuant to the Agreement, Merger Sub will be merged with and into Kenexa and each outstanding share of the common stock, par value $0.01 per share, of Kenexa (“Kenexa Common Stock”), other than shares of Kenexa Common Stock held by Buyer or Merger Sub (such holders, collectively, “Excluded Holders”), will be converted into the right to receive $46.00 in cash (the “Consideration”). The terms and conditions of the Transaction are more fully set forth in the Agreement.

You have requested our opinion as of the date hereof as to the fairness, from a financial point of view, to the holders of Kenexa Common Stock (other than Excluded Holders) of the Consideration to be paid to such holders in the Transaction.

We have assumed and relied upon the accuracy and completeness of the foregoing information, without independent verification of such information. We have not conducted any independent valuation or appraisal of any of the assets or liabilities (contingent or otherwise) of Kenexa or Buyer or concerning the solvency or fair value of Kenexa or Buyer, and we have not been furnished with any such valuation or appraisal. With respect to the financial forecasts utilized in our analyses, we have assumed, with the consent of Kenexa, that they have been reasonably prepared on bases reflecting the best currently available estimates and judgments as to the future financial performance of Kenexa. We assume no responsibility for and express no view as to any such forecasts or the assumptions on which they are based.

Further, our opinion is necessarily based on economic, monetary, market and other conditions as in effect on, and the information made available to us as of, the date hereof. We assume no responsibility for updating or revising our opinion based on circumstances or events occurring after the date hereof. We do not express any opinion as to the price at which shares of Kenexa Common Stock may trade at any time subsequent to the announcement of the Transaction. In connection with our engagement, we were not authorized to, and we did not, solicit indications of interest from third parties regarding a potential transaction with Kenexa, nor were we requested to consider, and our opinion does not address the relative merits of the Transaction as compared to any other transaction or business strategy in which Kenexa might engage or the merits of the underlying decision by Kenexa to engage in the Transaction.

In rendering our opinion, we have assumed, with the consent of Kenexa, that the Transaction will be consummated on the terms described in the Agreement, without any waiver or modification of any material terms or conditions. Representatives of Kenexa have advised us, and we have assumed, that the Agreement, when executed, will conform to the draft reviewed by us in all material respects. We also have assumed, with the consent of Kenexa, that obtaining the necessary governmental, regulatory or third party approvals and consents for the Transaction will not have an adverse effect on Kenexa, Buyer or the Transaction. We do not express any opinion as to any tax or other consequences that might result from the Transaction, nor does our opinion address any legal, tax, regulatory or accounting matters, as to which we understand that Kenexa obtained such advice as it deemed necessary from qualified professionals. We express no view or opinion as to any terms or other aspects (other than the Consideration to the extent expressly specified herein) of the Transaction, including, without limitation, the form or structure of the Transaction or any shareholder, voting, non-competition, non-solicitation or other agreements or arrangements entered into in connection with, or contemplated by, the Transaction. In addition, we express no view or opinion as to the fairness of the amount or nature of, or any other aspects relating to, the compensation to, or any agreements entered into with Buyer by, any officers, directors or employees of any parties to the Transaction, or class of such persons, relative to the Consideration or otherwise.

Lazard Frères & Co. LLC (“Lazard”) is acting as financial advisor to Kenexa in connection with the Transaction and will receive a fee for such services, a portion of which is payable upon the rendering of this opinion and a substantial portion of which is contingent upon the closing of the Transaction. We and Lazard Capital Markets LLC (an entity indirectly owned in large part by current and former managing directors of Lazard) in the past have provided certain investment banking services to Kenexa and in the past provided and currently are providing certain investment banking services to Buyer, for which we have received and may receive compensation, including, during the past two years, Lazard acting as financial advisor to Kenexa in connection with its acquisition of Salary.com, Inc. in October 2010, Lazard Capital Markets LLC serving as joint book-runner on a follow-on equity offering by Kenexa in May 2011 and Lazard acting as financial advisor to Buyer in connection with its sale of its Retail Store Solutions business in August 2012. In addition, in the ordinary course of their respective businesses, Lazard, Lazard Capital Markets LLC and their respective affiliates may actively trade securities of Kenexa and Buyer for their own accounts and for the accounts of their customers and, accordingly, may at any time hold a long or short position in such securities, and may also trade and hold securities on behalf of Kenexa and Buyer. The issuance of this opinion was approved by the Opinion Committee of Lazard.

Our engagement and the opinion expressed herein are for the benefit of the Board of Directors of Kenexa (in its capacity as such), and our opinion is rendered to the Board of Directors of Kenexa in connection with its evaluation of the Transaction. Our opinion is not intended to and does not constitute a recommendation to any stockholder as to how such stockholder should vote or act with respect to the Transaction or any matter relating thereto.

Based on and subject to the foregoing, we are of the opinion that, as of the date hereof, the Consideration to be paid to holders of Kenexa Common Stock (other than Excluded Holders) in the Transaction is fair, from a financial point of view, to such holders of Kenexa Common Stock (other than Excluded holders).


Very truly yours,
