The date on which the Closing actually takes place is referred to as the "Closing Date." Subject to the provisions of this Agreement, a certificate of merger satisfying the applicable requirements of the DGCL shall be duly executed by the Company in connection with the Closing and, concurrently with or as soon as practicable following the Closing, shall be filed with the Secretary of State of the State of Delaware. The Merger shall become effective at the time of the filing of such certificate of merger with the Secretary of State of the State of Delaware (the "Effective Time").

1.4 Certificate of Incorporation and Bylaws; Certificate of Organization.

(a) The certificate of incorporation of the Surviving Corporation shall be amended and restated as of the Effective Time in a form acceptable to Parent.

(b) The Bylaws of the Surviving Corporation shall be amended and restated as of the Effective Time to conform to the Bylaws of Merger Sub as in effect immediately prior to the Effective Time.

(c) The directors and officers of the Surviving Corporation immediately after the Effective Time shall be those individuals designated by Parent in its sole discretion.

1.5 Conversion of Shares.

(a) Subject to Sections 1.10 and 1.11, and subject to the provision for adjustment set forth below in Section 1.5(e), at the Effective Time, by virtue of the Merger and without any further action on the part of Parent, Merger Sub, the Company or any Company Stockholder:

(i) each share of Company Series B Preferred Stock issued and outstanding immediately prior to the Effective Time shall be converted into 0.084 shares of Parent Series E Stock;

(ii) each share of Company Series A Preferred Stock and Company Series A Preferred Stock issued and outstanding immediately prior to the Effective Time shall be converted into 0.08985 shares of Parent Series E Stock; and

(iii) each share of Company Series B Common Stock issued and outstanding immediately prior to the Effective Time shall be converted into 0.03385 shares of Parent Series E Stock.

(b) At the Effective Time, by virtue of the Merger and without any further action on the part of Parent, Merger Sub, the Company or any Company Stockholder, (i) any shares of Company Common Stock held by the Company (or held in the Company's treasury) immediately prior to the Effective Time shall be canceled and retired and shall cease to exist, and no consideration shall be delivered in exchange therefor; (ii) each share of Company Capital Stock owned by Parent or Merger Sub immediately prior to the Effective Time shall be canceled without payment of any consideration with respect thereto; and (ii) each share of the common stock, par value $0.01 per share, of Merger Sub outstanding immediately prior to the Effective Time shall be converted into one share of common stock of the Surviving Corporation (and each stock certificate of Merger Sub evidencing ownership of any such shares shall, as of the Effective Time, evidence ownership of such shares of common stock of the Surviving Corporation).

(c) If any shares of Company Series B Common Stock outstanding immediately prior to the Effective Time are unvested or are subject to a repurchase option, risk of forfeiture or other condition under any applicable restricted stock purchase agreement or other Contract or under which the Company has any rights, then the shares of Parent Series E Stock issued in exchange for such shares of Company Series B Common Stock will also be unvested and subject to the same repurchase option, risk of forfeiture or other condition, and the certificates representing such shares of Parent Series E Stock may accordingly be marked with appropriate legends. The Company shall take all action that may be necessary to ensure that, from and after the Effective Time: (i) any Merger Consideration payable to such holder shall remain so unvested and subject to such repurchase option, risk of forfeiture or other condition; (ii) such Merger Consideration need not be delivered until such time as such repurchase option, risk of forfeiture or other condition lapses or otherwise terminates; and (iii) Parent is entitled to exercise any such repurchase option or other right set forth in any such restricted stock purchase agreement or other Contract in accordance with the terms and conditions of such agreement or other Contract.

(d) No fractional shares of Parent Series E Stock shall be issued in connection with the Merger, and no certificates or scrip for any such fractional shares shall be issued. Any holder of Company Capital Stock who would otherwise be entitled to receive a fraction of a share of Parent Series E Stock (after aggregating all fractional shares of Parent Series E Stock issuable to such holder) shall, in lieu of each such fraction of a share and upon surrender of such holder's Company Stock Certificate(s) (as defined in Section 1.7), be paid in cash the dollar amount (rounded to the nearest whole cent), without interest, determined by multiplying each such fraction by $31.25.

(e) To the extent that the amount of the outstanding principal balance and accrued interest under the Parent Note is decreased prior to the Note Conversion (as defined below), a corresponding adjustment will be made to the conversion ratios set forth above in Section 1.5(a) using the same methodology that was used by the parties to generate those conversion ratios but substituting the decreased amounts owed under the Parent Note for the amounts set forth in Part 2.5(a) of the Disclosure Schedule. If, for example, the amount of the outstanding principal balance plus accrued interest is decreased from the amount set forth in Part 2.5(a) of the Disclosure Schedule to $2,550,000, then the ratios reflected in subsections (i), (ii) and (iii) of this Section 1.5(a) would become (i) 0.084 shares of Parent Series E Stock for each share of Company Series B Preferred Stock, (ii) 0.09065 shares of Parent Series E Stock for each share of Company Series A Preferred, and (iii) 0.03465 shares of Parent Series E Stock for each share of Company Series B Common, respectively.

1.6 Holdback Amount. The Holdback Amount shall be withheld from the Merger Consideration otherwise payable to the Company Stockholders at the Effective Time. The Holdback Amount shall constitute security for the indemnification obligations of the Company Stockholders pursuant to Section 7. Promptly following the Expiration Date, the shares of Parent Series E Stock that constitute the Holdback Amount, if any, shall be issued by Parent to the Company Stockholders in accordance with their respective Holdback Contribution Amount as set forth on the Spreadsheet. Notwithstanding the foregoing, Parent shall have the right to withhold and retain from the Holdback Amount any sum that may be owed (or that may be claimed to be owed) to any Indemnitee under Section 7 and Exhibit D. Any such Holdback Amount shall be retained by Parent and/or paid to the former Company Stockholders in accordance with Exhibit D.

1.7 Company Options.

(a) At the Effective Time, each outstanding Company Option that is unexpired, unexercised and outstanding immediately before the Effective Time shall be assumed and converted into a right to receive that number of Parent Options equal to (rounded down to the nearest whole share) the product of (A) the number of shares of Company Common Stock subject to such Company Option immediately prior to the Effective Time, multiplied by (B) the Option Exchange Ratio, each with an exercise price applicable to the Parent Option (rounded up to the nearest whole cent) equal to the per share exercise price applicable to the Company Option as of immediately before the Effective Time divided by the Option Exchange Ratio. The adjustments provided in this Section 1.7 to any Company Options, whether or not they are "incentive stock options" as defined in Section 422 of the Code, are intended to be effected in a manner which is consistent with Sections 424(a) and 409A of the Code. Each such assumed and converted Company Option shall be subject to the same vesting schedule (including vesting commencement date) and have the same expiration date as applied to such Company Option as of immediately prior to the Effective Time. As of the Effective Time, Company Options shall terminate and cease to be outstanding. As soon as reasonably practicable after the Effective Time and delivery to Parent of the Parent Common Stock Appraisal, Parent shall deliver to the former holders of Company Options converted pursuant to this Section 1.7 appropriate notices setting forth such

holders' rights pursuant to the applicable Parent Equity Plan and stock option agreements evidencing the Parent Options into which such Company Options are converted.

(b) Notwithstanding anything in this Agreement to the contrary, to the extent that the amount of the outstanding principal balance and accrued interest under the Parent Note is decreased prior to the Note Conversion (as defined below), a corresponding adjustment will be made to the numerator of the Option Exchange Ratio using the same methodology that was used by the parties to generate the numerator as of the date of this Agreement but substituting the decreased amounts owed under the Parent Note for the amounts set forth in Part 2.5(a) of the Disclosure Schedule. If, for example, the amount of the outstanding principal balance plus accrued interest is decreased from the amount set forth in Part 2.5(a) of the Disclosure Schedule to $2,550,000, then the numerator of the Option Exchange Ratio will be $1.083.

1.8 Closing of the Company's Transfer Books. At the Effective Time: (a) all shares of Company Capital Stock outstanding immediately prior to the Effective Time shall automatically be canceled and retired and shall cease to exist, and all holders of certificates representing shares of Company Capital Stock that were outstanding immediately prior to the Effective Time shall cease to have any rights as Company Stockholders; and (b) the stock transfer books of the Company shall be closed with respect to all shares of Company Capital Stock outstanding immediately prior to the Effective Time. No further transfer of any such shares of Company Capital Stock shall be made on such stock transfer books after the Effective Time. If, after the Effective Time, a valid certificate previously representing any shares of Company Capital Stock outstanding immediately prior to the Effective Time (each, a "Company Stock Certificate") is presented to the Surviving Corporation or Parent, such Company Stock Certificate shall be canceled and shall be exchanged as provided in Section 1.9.

1.9 Exchange of Certificates.

(a) As soon as reasonably practicable following the Effective Time, Parent will deliver to the holders of Company Stock Certificates (i) a letter of transmittal in customary form and containing such provisions as Parent may reasonably specify (which letter of transmittal shall contain provisions allowing for each Company Stockholder to become a party to the Parent Financing Agreements and specifically providing that each Company Stockholder shall agree to enter into a customary lock-up agreement in the event of an initial public offering of Parent Common Stock identical in all material respects to the lock-up agreement that other holders of Parent Common Stock will be required to execute) (a "Letter of Transmittal"), and (ii) instructions for use in effecting the surrender of Company Stock Certificates. Upon surrender of a Company Stock Certificate to Parent for exchange, together with a duly executed Letter of Transmittal and such other documents as may be reasonably required by Parent, the holder of such Company Stock Certificate shall be entitled to receive in exchange therefor the Merger Consideration that such holder has the right to receive pursuant to the provisions of Section 1.5, and the Company Stock Certificate so surrendered shall be canceled. Until surrendered as contemplated by this Section 1.9, each Company Stock Certificate shall be deemed, from and after the Effective Time, to represent only the right to receive Merger Consideration upon such surrender as contemplated by this Section 1.9. If any Company Stock Certificate shall have been lost, stolen or destroyed, Parent may, in its discretion and as a condition precedent to the delivery of any Merger Consideration therefor, require the owner of such lost, stolen or destroyed Company Stock Certificate to provide an appropriate affidavit of lost certificate.

(b) To the fullest extent permitted by applicable law, Parent and the Surviving Corporation shall be relieved of any and all liability to any holder or former holder of Company Capital Stock or Company Options for any Merger Consideration delivered to any public official in good faith pursuant to any applicable abandoned property law, escheat law or similar Legal Requirement.

1.10 Dissenting Shares.

(a) Notwithstanding anything to the contrary contained in this Agreement, shares of Company Capital Stock held by a holder who has made a demand for appraisal of such shares of Company Capital Stock in accordance with Section 262 of the DGCL ("Dissenting Shares") shall not be converted into or represent the right to receive Merger Consideration in accordance with Section 1.5, but shall be entitled only to such rights as are granted by the DGCL to a holder of Dissenting Shares.

(b) If any Dissenting Shares shall lose their status as such (through failure to perfect or otherwise), then, as of the later of the Effective Time or the date of loss of such status, such shares shall automatically be converted into and shall represent only the right to receive Merger Consideration in accordance with Section 1.5, without interest thereon, upon surrender of the Company Stock Certificate representing such shares.

(c) The Company shall give Parent (i) prompt notice of any written demand for appraisal received by the Company prior to the Effective Time pursuant to the DGCL, any withdrawal of any such demand and any other demand, notice or instrument delivered to the Company prior to the Effective Time pursuant to the DGCL, and (ii) the opportunity to participate in all negotiations and proceedings with respect to any such demand, notice or instrument. The Company shall not make any payment or settlement offer prior to the Effective Time with respect to any such demand, notice or instrument unless Parent shall have given its written consent to such payment or settlement offer (which consent shall not be unreasonably withheld or delayed).

1.11 Withholding Rights. Parent and the Surviving Corporation shall be entitled to deduct and withhold from the consideration otherwise deliverable under this Agreement, and from any other payments otherwise required pursuant to this Agreement, to holders of Company Capital Stock and Company Options, such amounts as Parent or the Surviving Corporation is required to deduct and withhold with respect to any such deliveries and payments under the Code or any provision of state, local, provincial or foreign Tax law. To the extent that amounts are so withheld, such withheld amounts shall be treated for all purposes of this Agreement as having been delivered and paid to such holders in respect of which such deduction and withholding was made

1.12 Further Action. If, at any time after the Effective Time, any further action is determined by Parent or the Surviving Corporation to be necessary or desirable to carry out the purposes of this Agreement or to vest the Surviving Corporation with full right, title and possession of and to all rights and property of Merger Sub and the Company, then the officers and directors of Parent and Merger Sub shall be fully authorized to take such action.

(iii) Legal Requirements and Deadlines. Each item of Company IP that is Registered IP is and at all times has been in compliance with all legal requirements and all filings, payments, and other actions required to be made or taken to maintain such item of Company IP in full force and effect have been made by the applicable deadline.

(b) each Indemnitor shall make available to Parent any documents and materials in his possession or control that may be necessary to the defense of such claim or Legal Proceeding; and

(c) Parent shall have the right to settle, adjust or compromise such claim or Legal Proceeding.

Parent shall give the Representative prompt notice of the commencement of any such Legal Proceeding against Parent, the Surviving Corporation or the Company; provided, however, that any failure on the part of Parent to so notify the Representative shall not limit any of the obligations of the Indemnitors under Section 7 (except to the extent such failure materially prejudices the defense of such Legal Proceeding). If Parent does not elect to proceed with the defense of any such claim or Legal Proceeding, the Representative may proceed with the defense of such claim or Legal Proceeding with counsel reasonably satisfactory to Parent; provided, however, that the Representative may not settle, adjust or compromise any such claim or Legal Proceeding without the prior written consent of Parent, which consent shall not be unreasonably withheld.

Each party to this Agreement: (i) expressly and irrevocably consents and submits to the jurisdiction of each state and federal court located in the State of Iowa (and each appellate court located in the State of Iowa) in connection with any such Legal Proceeding; (ii) agrees that each state and federal court located in the State of Iowa shall be deemed to be a convenient forum; and (iii) agrees not to assert (by way of motion, as a defense or otherwise), in any such Legal Proceeding commenced in any state or federal court located in the State of Iowa, any claim that such party is not subject personally to the jurisdiction of such court, that such Legal Proceeding has been brought in an inconvenient forum, that the venue of such proceeding is improper or that this Agreement or the subject matter of this Agreement may not be enforced in or by such court.

(c) Indemnification Claims. Any claim for indemnification, compensation or reimbursement pursuant to Section 7 (and, at the option of any Indemnitee, any other claim for a monetary remedy, such as in the case of a claim based upon intentional misconduct, intentional misrepresentation or fraud, relating to this Agreement or the Transaction after the Closing) shall be brought and resolved exclusively in accordance with Exhibit D (it being understood that, for the avoidance of doubt and without limiting any portion of Section 8.7(b): (i) at the option of any Indemnitee, any claim based upon Fraud may be brought and resolved in accordance with Section 8.7(b) rather than in accordance with Exhibit D; and (ii) nothing in this Section 8.7(c) shall prevent Parent from seeking preliminary injunctive relief from a court of competent jurisdiction).

Parent may freely assign any or all of its rights under this Agreement (including its indemnification rights under Section 5), in whole or in part, to any other Person without obtaining the consent or approval of any other party hereto or of any other Person.

8.10 Waiver. No failure on the part of any Person to exercise any power, right, privilege or remedy under this Agreement, and no delay on the part of any Person in exercising any power, right, privilege or remedy under this Agreement, shall operate as a waiver of such power, right, privilege or remedy; and no single or partial exercise of any such power, right, privilege or remedy shall preclude any other or further exercise thereof or of any other power, right, privilege or remedy. No Person shall be deemed to have waived any claim arising out of this Agreement, or any power, right, privilege or remedy under this Agreement, unless the waiver of such claim, power, right, privilege or remedy is expressly set forth in a written instrument duly executed and delivered on behalf of such Person; and any such waiver shall not be applicable or have any effect except in the specific instance in which it is given.

8.11 Waiver of Jury Trial. To the maximum extent permitted by law, each of the parties hereto hereby irrevocably waives any and all right to trial by jury in any Legal Proceeding arising out of or related to this Agreement or the transactions contemplated hereby.

8.15 Entire Agreement. This Agreement and the other agreements referred to herein set forth the entire understanding of the parties hereto relating to the subject matter hereof and thereof and supersede all prior agreements and understandings among or between any of the parties relating to the subject matter hereof and thereof.

This Agreement has been duly executed and delivered by the Stockholder, and this Agreement is, and each of the other related documents when executed and

Section 2.2 No Conflicts. The execution and delivery of this Agreement by Stockholder and the consummation of the transactions contemplated hereby: (i) will not conflict or violate any court order, judgment or decree applicable to the Stockholder or by which the property of Stockholder is bound or affected, (ii) will not conflict with or result in any breach of or constitute a default under any contract or agreement to which Stockholder is a party or by which Stockholder or Stockholder's property is bound or affected, which conflict, violation, breach or default would adversely affect Stockholder's ability to perform Stockholder's obligations hereunder, and (iii) do not and will not require any consent or other action by any third party under any provision of any agreement, contract or other instrument binding on Stockholder.

Section 2.3 Title. Stockholder has good and valid title to the Shares, and upon payment of the Purchase Price for the Shares, in accordance with the terms hereof, the Company will acquire good and valid title to the Shares, free and clear of any liens, encumbrances, equities and claims.

Stockholder has been provided with an adequate opportunity to consult with Stockholder's own counsel with respect to this Agreement.

ARTICLE III

DISPUTE RESOLUTIONS PROCEDURES

Subject to the provisions of Section 8.7(c) of the Agreement, any claim for indemnification, compensation or reimbursement pursuant to Section 7 of the Agreement (and, at the option of any Indemnitee, any other claim for a monetary remedy, such as in the case of a claim based upon Fraud, relating to the Agreement or the Merger after the Closing) shall be brought and resolved exclusively as follows:

(a) If any Indemnitee has or claims in good faith to have incurred or suffered Damages for which it is or may be entitled to indemnification, compensation or reimbursement under Section 7 of the Agreement or for which it is or may otherwise be entitled to a monetary remedy relating to the Agreement or the Merger, such Indemnitee may deliver a claim notice (a "Claim Notice") to the Representative. Each Claim Notice shall: (i) state that the Indemnitee believes in good faith that the Indemnitee is entitled to indemnification, compensation or reimbursement under Section 7 of the Agreement or is or may otherwise be entitled to a monetary remedy relating to the Agreement or the Transaction; (ii) contain a brief description of the facts and circumstances supporting the Indemnitee's claim; and (iii) contain a non-binding, preliminary, good faith estimate of the amount to which the Indemnitee claims to be entitled (the aggregate amount of such estimate, as it may be modified by the Indemnitee in good faith from time to time, being referred to as the "Claimed Amount").

(b) During the 20 day period commencing upon receipt by the Representative of a Claim Notice from an Indemnitee (the "Dispute Period"), the Representative may deliver to the Indemnitee a written response (the "Response Notice") in which the Representative: (i) agrees that the full Claimed Amount is owed to the Indemnitee; (ii) agrees that part, but not all, of the Claimed Amount is owed to the Indemnitee; or (iii) indicates that no part of the Claimed Amount is owed to the Indemnitee. If the Response Notice is delivered in accordance with clause "(ii)" or "(iii)" of the preceding sentence, the Response Notice shall also contain a brief description of the facts and circumstances supporting the Representative's claim that only a portion or no part of the Claimed Amount is owed to the Indemnitee, as the case may be (any part of the Claimed Amount that is not agreed to be owed to the Indemnitee pursuant to the Indemnitee's Claim Notice being referred to as the "Contested Amount"). If a Response Notice is not received by the Indemnitee from the Representative prior to the expiration of the Dispute Period, then the Representative shall be conclusively deemed to have agreed that an amount equal to the full Claimed Amount is owed to the Indemnitee.

(c) If the Representative in its Response Notice agrees that the full Claimed Amount is owed to the Indemnitee, the Representative shall include in such Response Notice the Representative's irrevocable written agreement that the full Claimed Amount (up to the amount of the Holdback Amount) may be retained by Parent from the Holdback Amount. If no Response Notice is received by the Indemnitee from the Representative prior to the expiration of the Dispute Period, it shall be conclusively agreed that Parent shall be entitled to retain the full Claimed Amount from the Holdback Amount.

(d) If the Representative in the Response Notice agrees that part, but not all, of the Claimed Amount is owed to the Indemnitee (the "Agreed Amount"), the Representative shall include in such Response Notice the Representative's irrevocable written agreement that the Agreed Amount may be retained by Parent from the Holdback Amount.

(e) If any Response Notice expressly indicates that there is a Contested Amount, the Representative and the Indemnitee shall attempt in good faith to resolve the dispute related to the Contested Amount. If the Representative and the Indemnitee resolve such dispute, such resolution

shall be binding on the Representative, the Indemnitors and such Indemnitee and a settlement agreement stipulating the amount owed to such Indemnitee (the "Stipulated Amount") shall be signed by such Indemnitee and the Representative. The Representative shall cause to be included in such settlement agreement its irrevocable written agreement that the Stipulated Amount may be retained by Parent from the Holdback Amount.

(f) In the event that there is a dispute relating to any Claim Notice or Contested Amount (whether it is a matter between the Indemnitee, on the one hand, and the Representative, on the other hand, or it is a matter that is subject to a claim or Legal Proceeding asserted or commenced by a third party brought against the Indemnitee or the Company in a litigation or arbitration), such dispute (an "Arbitrable Dispute") shall be settled by binding arbitration. Notwithstanding the preceding sentence, nothing in this Exhibit D shall prevent the Indemnitee from seeking preliminary injunctive relief from a court of competent jurisdiction pending settlement of any Arbitrable Dispute.

(i) Except as herein specifically stated, any Arbitrable Dispute shall be resolved by arbitration in Ames, Iowa in accordance with JAMS' Comprehensive Arbitration Rules and Procedures (the "JAMS Rules") then in effect. However, in all events, the provisions contained herein shall govern over any conflicting rules which may now or hereafter be contained in the JAMS Rules. Any judgment upon the award rendered by the arbitrator shall be entered in any court having jurisdiction over the subject matter thereof. The arbitrator shall have the authority to grant any equitable and legal remedies that would be available if any judicial proceeding was instituted to resolve an Arbitrable Dispute. The final decision of the arbitrator, as entered by a court of competent jurisdiction, will be furnished by the arbitrator to the Representative and the Indemnitee in writing and will constitute a final, conclusive and non-appealable determination of the issue in question, binding upon the Representative, the Indemnitors and the Indemnitee, and an order with respect thereto may be entered in any court of competent jurisdiction.

(ii) Any such arbitration will be conducted before a single arbitrator who will be compensated for his or her services at a rate to be determined by the Indemnitee and the Representative or by JAMS, but based upon reasonable hourly or daily consulting rates for the arbitrator in the event the parties are not able to agree upon his or her rate of compensation.

(iii) The arbitrator shall be mutually agreed upon by the Indemnitee and the Representative. In the event the Indemnitee and the Representative are unable to agree within 20 days following submission of the dispute to JAMS by one of the parties, JAMS will have the authority to select an arbitrator from a list of arbitrators who satisfy the criteria set forth in clause "(iv)" hereof.

(iv) No arbitrator shall have any past or present family, business or other relationship with the Indemnitee, Parent, the Surviving Corporation, the Company, the Representative, any of the Indemnitors or any "affiliate" (as such term is defined in Rule 12b-2 of the Securities Act), director or officer thereof, unless following full disclosure of all such relationships, the Indemnitee and the Representative agree in writing to waive such requirement with respect to an individual in connection with any dispute.

(v) The arbitrator shall be instructed to hold an up to eight hour, one day hearing regarding the disputed matter within 60 days of his designation and to render an award (without written opinion) no later than 10 days after the conclusion of such hearing, in each case unless otherwise mutually agreed in writing by the Indemnitee and the Representative.

(vi) No discovery other than an exchange of relevant documents may occur in any arbitration commenced under the provisions of this Exhibit D. The Indemnitee and the Representative agree to act in good faith to promptly exchange relevant documents.

(vii) The Indemnitee and the Representative (on behalf of the Indemnitors) will each pay 50% of the initial compensation to be paid to the arbitrator in any such arbitration and 50% of the costs of transcripts and other normal and regular expenses of the arbitration proceedings; provided, however, that: (A) the prevailing party in any arbitration will be entitled to an award of attorneys' fees and costs; and (B) all costs of arbitration, other than those provided for above, will be paid by the losing party and the arbitrator will be authorized to determine the identity of the prevailing party and the losing party.

(viii) The arbitrator chosen in accordance with these provisions will not have the power to alter, amend or otherwise affect the terms of these arbitration provisions or any other provisions contained in this Exhibit D or the Agreement.

(ix) Except as specifically otherwise provided in this Exhibit D or the Agreement, arbitration will be the sole and exclusive remedy of the parties for any Arbitrable Dispute or any other dispute arising out of or relating to this Exhibit D or the Agreement.

(g) Upon resolution of the arbitration described in clause "(f)" of this Exhibit D, the Representative shall, within two business days following the entry of the arbitrator's decision by a court of competent jurisdiction, or such other period of time as may be set forth in the arbitrator's decision, provide Parent with its irrevocable written agreement that the amount of the award specified in the arbitrator's decision, if any, may be retained by Parent from the Holdback Amount.

(h) If: (i) Parent has retained any Holdback Amount; and (ii) it is subsequently agreed to by Parent and the Representative (or determined by binding arbitration as described above) that the Indemnitees are not entitled to retain any portion of the Holdback Amount, then, within five business days after such agreement or determination is made, Parent shall pay to the former Company Stockholders entitled thereto (in accordance with their Holdback Contribution Amount as set forth in the Spreadsheet) their portion of the Holdback Amount.
