All shares of Parent Common Stock and Parent Preferred Stock, as applicable, issued upon surrender of a Certificate in accordance with the terms of this Article II shall be deemed to have been issued in full satisfaction of all rights pertaining to the Greyhound Shares or Iris Shares formerly represented by such Certificate.

(e) Termination of Exchange Fund. Any portion of the Exchange Fund that remains undistributed to the holders of Greyhound Capital Stock and Iris Capital Stock at the end of six months after the Effective Time shall be delivered to Parent, upon demand, and any holders of the Greyhound Capital Stock and Iris Capital Stock who have not theretofore complied with this Article II shall thereafter look only to Parent for merger consideration and any dividends or other distributions with respect to the Parent Common Stock and Parent Preferred Stock to which they are entitled pursuant to this Article II. Any portion of the Exchange Fund remaining unclaimed by holders of Greyhound Shares and Iris Shares as of a date which is immediately prior to such time as such portion would otherwise escheat to or become property of any government entity shall, to the extent permitted by applicable law, become the property of Parent free and clear of any claims or interest of any person previously entitled thereto.

(f) No Liability. None of the Exchange Agent, Parent or the Surviving Corporations shall be liable to any holder of Greyhound Shares or Iris Shares for any such Greyhound Shares and Iris Shares, merger consideration (or dividends or distributions with respect thereto), or cash delivered to a public official pursuant to any abandoned property, escheat or similar Law.

(g) Withholding Rights. Each of the Surviving Corporations and Parent shall be entitled to deduct and withhold from the consideration otherwise payable pursuant to this Agreement to any holder of Greyhound Shares and Iris Shares or holder of a Greyhound Stock Option, Iris Stock Option or Greyhound SAR such amounts as it is required to deduct and

withhold with respect to such consideration under the Code, or any provision of state, local or foreign tax law. To the extent that amounts are so withheld by the Surviving Corporations or Parent, as the case may be, and paid to the applicable tax authority, such withheld amounts shall be treated for all purposes of this Agreement as having been paid to the holder of such Greyhound Shares or Iris Shares in respect of which such deduction and withholding was made by the Surviving Corporations or Parent, as the case may be.

(h) Lost Certificates. If any Certificate shall have been lost, stolen or destroyed, upon the making of an affidavit of that fact by the person claiming such Certificate to be lost, stolen or destroyed and, if required by Parent, the posting by such person of a bond, in such reasonable amount as Parent may direct and in form and substance satisfactory to Parent and Exchange Agent, as indemnity against any claim that may be made against it with respect to such Certificate, the Exchange Agent will issue in exchange for such lost, stolen or destroyed Certificate merger consideration to which such person is entitled and any dividends or other distributions to which such person is entitled pursuant to this Article II.

SECTION 2.04. Stock Transfer Books. (a) At the Effective Time, the stock transfer books of Greyhound shall be closed and there shall be no further registration of transfers of Greyhound Shares thereafter on the records of Greyhound. From and after the Effective Time, the holders of Certificates representing Greyhound Shares outstanding immediately prior to the Effective Time shall cease to have any rights with respect to such Greyhound Shares except as otherwise provided in this Agreement or by Law. On or after the Effective Time, any Certificates representing shares of Greyhound Capital Stock presented to the Exchange Agent or Parent for any reason shall be converted into Greyhound Merger Consideration and any dividends or other distributions to which the holder thereof is entitled pursuant to this Article II.

(b) At the Initial Effective Time, the stock transfer books of Iris shall be closed and there shall be no further registration of transfers of Iris Shares thereafter on the records of Iris. From and after the Initial Effective Time, the holders of Certificates representing Iris Shares outstanding immediately prior to the Initial Effective Time shall cease to have any rights with respect to such Iris Shares except as otherwise provided in this Agreement or by Law. On or after the Initial Effective Time, any Certificates representing shares of Iris Capital Stock presented to the Exchange Agent or Parent for any reason shall be converted into the Iris Merger Consideration and any dividends or other distributions to which the holder thereof is entitled pursuant to this Article II.

SECTION 2.05. Stock Options.

(a) Greyhound Stock Options. At the Effective Time, all options (the “Greyhound Stock Options”) outstanding, whether or not exercisable and whether or not vested, under the Greyhound Stock Incentive Plan (the “Greyhound Stock Option Plan”), shall, by virtue of the Greyhound Merger and this Agreement, and without any further action on the part of Greyhound, Parent or the holder thereof, be assumed by Parent by virtue of this Agreement and without any further action on the part of Parent, and all references to Greyhound in the Greyhound Stock Option Plan and the applicable stock option agreements issued thereunder shall be deemed to refer to Parent. Each Greyhound Stock Option assumed by Parent (each, a “Greyhound Substitute Option”) shall be exercisable upon the same terms and conditions as

under the applicable Greyhound Stock Option Plan and the applicable option agreement issued thereunder, except that (A) each such Greyhound Substitute Option shall be exercisable for, and represent the right to acquire, that whole number of shares of Parent Common Stock (rounded down to the nearest whole share) equal to the number of shares of Greyhound Common Stock subject to such Greyhound Stock Option multiplied by the Greyhound Option Exchange Ratio; and (B) the option price per share of Parent Common Stock shall be an amount equal to the option price per share of Greyhound Common Stock subject to such Greyhound Stock Option in effect immediately prior to the Effective Time divided by the Greyhound Option Exchange Ratio (the option price per share, as so determined, being rounded upward to the nearest full cent).

(b) Iris Stock Options. All options (the “Iris Stock Options”) outstanding, whether or not exercisable and whether or not vested, at the Initial Effective Time under the 2003 Stock Purchase and Option Plan and the 2004 Stock Purchase and Option Plan of Iris (collectively, the “Iris Stock Option Plans”), shall, if not exercised immediately prior to the Initial Effective Time, expire and be cancelled in their entirety as of the Initial Effective Time in accordance with the terms of the Iris Stock Option Plans. Iris may offer the holders of exercisable and vested Iris Stock Options the opportunity to receive a cash payment in exchange therefor (such amount in the aggregate, the “Iris Option Payment Amount”). In addition, certain recipients of the Iris Option Payment Amount (the “Reinvestment Holders”) may be afforded the opportunity to acquire for cash shares of Parent Capital Stock in amounts to be determined prior to the Initial Effective Time. The amount paid to Parent in respect thereof is referred to herein as the “Reinvestment Proceeds” and the shares of Parent Capital Stock issued in respect thereof are referred to herein as the “Reinvestment Shares.”

(c) Greyhound Stock Appreciation Right. At the Effective Time, that certain stock appreciation right set forth on Section 4.03(a) of the Greyhound Disclosure Schedule (the “Greyhound SAR”), to the extent then outstanding, shall be assumed by Parent by virtue of the Greyhound Merger and this Agreement and without any further action on the part of Parent, Greyhound or the holder thereof; and all references to Greyhound in the agreement evidencing the Greyhound SAR (the “Greyhound SAR Agreement”) shall be deemed to refer to Parent. The Greyhound SAR so assumed by Parent (the “Greyhound Substitute SAR”) shall be exercisable upon the same terms and conditions as under the Greyhound SAR Agreement, except that (A) each such Greyhound Substitute SAR shall be exercisable for, and represent the right to receive the appreciation in that whole number of shares of Parent Common Stock and Parent Preferred Stock (in each case, rounded down to the nearest whole share) equal to the number of shares of Greyhound Common Stock and Greyhound Class B Preferred Stock multiplied by the Greyhound SAR Common Exchange Ratio and the Greyhound SAR Preferred Exchange Ratio, as applicable; and (B) the base price of the Greyhound Substitute SAR shall be an amount equal to the base price per share of Greyhound Common Stock and Greyhound Class B Preferred Stock subject to such Greyhound SAR in effect immediately prior to the Effective Time divided by the Greyhound SAR Common Exchange Ratio and the Greyhound SAR Preferred Exchange Ratio, as applicable (the base price per share, as so determined, being rounded upward to the nearest full cent).

(d) As soon as practicable after the Effective Time, Parent shall deliver, or cause to be delivered, to each holder of a Greyhound Substitute Option and the Greyhound Substitute SAR an appropriate notice setting forth such holder’s rights pursuant thereto and such

Greyhound Substitute Option and the Greyhound Substitute SAR shall continue in effect on the same terms and conditions (including any antidilution provisions, and subject to the adjustments required by this Section 2.05 after giving effect to the Mergers). Parent shall comply with the terms of all such Greyhound Substitute Options and the Greyhound Substitute SAR and ensure, to the extent required by, and subject to the provisions of the Greyhound Stock Option Plan that the assumption of the Greyhound Substitute Options and the Greyhound Substitute SAR pursuant to this Section 2.05 is effected in a manner consistent with the requirements of Section 409A, 424 and, to the extent applicable, 422 of the Code. Parent shall take all corporate action necessary to reserve for issuance a sufficient number of shares of Parent Common Stock for delivery upon exercise of Greyhound Substitute Options and Greyhound Substitute SAR pursuant to the terms set forth in this Section 2.05.

SECTION 2.06. Merger Consideration Adjustments. (a) Estimated Statements. The Parties contemplate that Iris will have Working Capital on the Closing Date (the “Iris Closing Working Capital”), as calculated in accordance with this Agreement and in accordance with and as set forth on the Form Working Capital Statement attached hereto as Schedule 2.06(a) (the “Iris Form Working Capital Statement”), of negative Fourteen Million Seven Hundred Fifty Thousand Dollars (($14,750,000)) (the “Iris Working Capital Target”). The Parties contemplate that Iris will have Net Debt on the Closing Date (the “Closing Net Debt Balance”) of $144,800,000 (the “Net Debt Target”). At least two (2) Business Days prior to the Closing, Iris shall deliver to Greyhound a written statement (the “Estimated Statement”) setting forth (a) Iris’s good faith estimate of the amount of the Closing Working Capital (the “Estimated Working Capital”) and (b) Iris’s good faith estimate of the amount of the Closing Net Debt Balance (the “Estimated Net Debt Balance”), together with such schedules and data with respect to the determination thereof as may be reasonably necessary to support such Estimated Statement. The Estimated Statement shall be signed by the Chief Financial Officer of Iris. Following delivery of the Estimated Statement, Iris shall provide Greyhound and its Representatives with reasonable access to the employees, agreements and books and records of Iris to verify the accuracy of such amounts, all to the extent deemed reasonably necessary by Greyhound and in a manner not unreasonably disruptive to Iris’s business. In the event that Greyhound does not agree with Iris’s calculations of Estimated Working Capital or Estimated Net Debt Balance, Iris and Greyhound shall negotiate in good faith to mutually agree on acceptable estimates, and Iris shall consider in good faith any proposed comments or changes that Greyhound may reasonably suggest; provided, however, that Iris’s failure to include any changes proposed by Greyhound, or the acceptance by Greyhound of the Estimated Statement, shall not limit or otherwise affect Greyhound’s remedies under this Agreement, including Greyhound’s right to include such changes or other changes in the Closing Statement, or constitute an acknowledgment by Greyhound of the accuracy of the Estimated Statement. The Aggregate ▇▇▇▇ ▇▇▇▇ Merger Consideration shall be (i) decreased on a dollar for dollar basis by the amount, if any, by which the Estimated Working Capital is less than the Iris Working Capital Target (but only if the amount of such shortfall is greater than One Million Dollars ($1,000,000), (ii) increased on a dollar for dollar basis by the amount, if any, by which the Estimated Working Capital is greater than Iris Working Capital Target (but only if the amount of such excess is greater than One Million Dollars ($1,000,000), (iii) decreased on a dollar for dollar basis by the amount, if any, by which the Estimated Net Debt Balance is greater than the Net Debt Target, and/or (iv) increased on a dollar for dollar basis by the amount, if any, by which the Estimated Net Debt Balance is

less than the Net Debt Target. Schedule 2.06(a) to this Agreement contains hypothetical examples of the calculations of the Closing Working Capital and Closing Net Debt Balance.

(b) Closing Statement. Parent shall cause to be prepared and, as soon as practical, but in no event later than forty five (45) days after the Closing Date, shall cause to be delivered to the Stockholder Representative, a calculation of the Iris Closing Working Capital and the Closing Net Debt Balance (the “Closing Statement”) together with such schedules and data with respect to the determination thereof as may be appropriate to support such Closing Statement. Following delivery of the Closing Statement, Parent shall provide the Stockholder Representative and its representatives with reasonable access to the records and personnel of Iris, solely for the purpose of reviewing the Closing Statement in accordance with this Agreement, all to the extent deemed reasonably necessary by the Stockholder Representative and in a manner not unreasonably disruptive to Parent’s business. For purposes of this Agreement, Working Capital shall be calculated in accordance with this Agreement (including Schedule 2.06(a) to this Agreement and Section 2.06(e)) and with GAAP applied using the same accounting methods, policies, practices and procedures, with consistent classifications, judgments and estimation methodology, as were used in the preparation of the 2008 audited financial statements constituting part of the Iris Financial Statements.

(i) If the Stockholder Representative disagrees in whole or in part with the Closing Statement, then within thirty (30) days after its receipt of the Closing Statement, it shall notify Parent of such disagreement in writing (the “Notice of Disagreement”), setting forth in reasonable detail the particulars of any such disagreement. Parent shall provide access to the Stockholder Representative and its representatives to all of its working papers, schedules, personnel and calculations used in the preparation of the Closing Statement and the determination of the Closing Working Capital and the Closing Net Debt Balance. To be effective, any such Notice of Disagreement shall include a copy of the Closing Statement marked to indicate those specific line items that are in dispute (the “Disputed Line Items”) and shall be accompanied by the Stockholder Representative’s calculation of each of the Disputed Line Items and the Stockholder Representative’s revised Closing Statement setting forth its determination of the Closing Working Capital and the Closing Net Debt Balance. To the extent the Stockholder Representative provides a Notice of Disagreement within such thirty (30) day period, all items that are not Disputed Line Items shall be final, binding and conclusive for all purposes hereunder. In the event that the Stockholder Representative does not provide a Notice of Disagreement within such thirty (30) day period, the Stockholder Representative shall be deemed to have accepted in full the Closing Statement as prepared by Parent, which shall be final, binding and conclusive for all purposes hereunder.

(ii) In the event any Notice of Disagreement is timely provided and contains the proper information as aforesaid, Parent and the Stockholder Representative shall use commercially reasonable efforts for a period of twenty (20) days (or such longer period as they may mutually agree) to resolve any Disputed Line Items. During such twenty (20) day period, Parent and the Stockholder Representative and their

representatives shall have access to the working papers, schedules, calculations and personnel of the other used in the preparation of the Closing Statement and the Notice of Disagreement and the determination of the Closing Working Capital, the Closing Net Debt Balance and Disputed Line Items. If, at the end of such period, Parent and the Stockholder Representative are unable to resolve such Disputed Line Items, then such Disputed Line Items shall be referred to Deloitte & Touche LLP or, if Deloitte & Touche LLP declines to serve, such other firm selected by the mutual agreement of Parent and Stockholder Representative (the “Settlement Accountants”). Parent and the Stockholder Representative will enter into reasonable and customary arrangements for the services to be rendered by the Settlement Accountants under this Section 2.06(c). The Settlement Accountants shall be directed to determine as promptly as practicable (and in any event within thirty (30) days from the date that the dispute is submitted to it), whether the Closing Statement was prepared in accordance with the standards set forth in this Section 2.06 and whether and to what extent (if any) the Closing Working Capital and/or the Closing Net Debt Balance require adjustment, limiting its review, however, only to the Disputed Line Items not previously resolved. The Settlement Accountants shall resolve each Disputed Line Item by calculating such Disputed Line Item in accordance with this Agreement (for each such Disputed Line Item, the amount so calculated is referred to as the “SA Determined Amount”) and establishing as the final amount of such Disputed Line Item the applicable SA Determined Amount, and the Settlement Accountants shall prepare the definitive Closing Statement reflecting the SA Determined Amount for each Disputed Line Item. Parent and the Stockholder Representative shall each furnish to the Settlement Accountants such work papers and other documents and information relating to the disputed issues, and shall provide interviews and answer questions, as such Settlement Accountants may reasonably request. The determination of the Settlement Accountants shall be final, conclusive and binding on the Parties. The amounts determined to be the Closing Working Capital and the Closing Net Debt Balance pursuant to this Section 2.06(c) shall constitute the “Final Working Capital,” and the “Final Net Debt Balance,” respectively.

(iii) The fees and expenses of the Settlement Accountants shall be allocated between Parent and the Iris Indemnifying Parties in such manner that the Iris Indemnifying Parties shall be responsible for that portion of the fees and expenses equal to such fees and expenses multiplied by a fraction the numerator of which is the aggregate dollar value of Disputed Line Items submitted to the Settlement Accountants that are resolved in a manner further from the position submitted to the Settlement Accountants by the Stockholder Representative and closer to the position submitted to the Settlement Accountants by Parent (as finally determined by the Settlement Accountants), and the denominator of which is the total aggregate dollar value of the Disputed Line Items so submitted, and Parent shall be responsible for the remainder of such fees and expenses.

(d) Post Closing Adjustment Amounts.

(i) Within three (3) Business Days after determination of the Final Working Capital and the Final Net Debt Balance, the Aggregate ▇▇▇▇ ▇▇▇▇ Merger Consideration shall be, if necessary, further adjusted so that, after taking into account any adjustments

under Section 2.06(a), the former holders of Iris Capital Stock and options (in accordance with their Pro Rata Portions) shall have received or made payments in an amount exactly equal to the amount that would have been made under Section 2.06(a) if the Estimated Working Capital had equaled the Final Working Capital and the Estimated Net Debt Balance had equaled the Final Net Debt Balance. All payments to be made under this Section 2.06(d)(i) shall be made on a net basis taking into account any adjustments under Section 2.06(a).

(ii) If a net payment is required to be made by Parent pursuant to Section 2.06(d)(i), then Parent, Greyhound and/or Iris shall pay (and shall be jointly and severally obligated to pay), or cause to be paid, an amount equal to such net payment to the former holders of Iris Capital Stock and Iris Stock Options in accordance with their Pro Rata Portions. Each such amount shall be delivered by wire transfer of immediately available funds pursuant to instructions delivered to Parent by the Stockholder Representative prior to the Closing Date.

(iii) If a net payment is required to be made to Parent pursuant to Section 2.06(d)(i), then each former holder of Iris Capital Stock and options shall pay an amount equal to such net payment to Parent in accordance with each such holder’s Pro Rata Portion. Each such amount shall be delivered by wire transfer of immediately available funds to an account designated in writing by Parent at least two (2) days prior to such payment. At Parent’s election, such payment obligation of the Iris Minority Holders may also be satisfied by Parent instructing the Escrow Agent to release a corresponding amount from the Escrow Account.

(iv) If Parent is ever required to issue any shares of Parent Capital Stock pursuant to the Greyhound Substitute SAR or to pay any cash pursuant to the Greyhound Substitute SAR or the Greyhound Management Incentive Award Program, then Parent shall take one of the actions specified in Schedule 2.06(d)(IV).

(e) Calculations. Except as otherwise expressly provided in this Agreement, including Schedule 2.06(a), the Parties agree that no amount shall be (or is intended to be) included, in whole or in part (either as an increase or a reduction), more than once in the calculation of (including any component of) the Final Working Capital or the Final Net Debt Balance or any other calculated amount pursuant to this Agreement if the effect of such additional inclusion (either as an increase or a reduction) would be to cause such amount to be over- or under-counted for purposes of such calculation. The Parties further agree that if any provision of this Agreement requires an amount or calculation to be “determined in accordance with this Agreement and GAAP” (or words of similar import), then to the extent that the terms of this Agreement (including Schedule 2.06(a)) expressly conflict with, or are expressly inconsistent with, GAAP in connection with such determination, the terms of this Agreement (including Schedule 2.06(a)) shall control.

SECTION 2.07. Certain Adjustments; Aggregate Limits.

(a) If, between the date of this Agreement and the Effective Time, there is a reclassification, recapitalization, stock split, split-up, stock dividend, combination or exchange of

shares with respect to, or rights issued in respect of, Greyhound Stock or Iris Stock, the Greyhound Merger Consideration and Iris Merger Consideration shall be adjusted accordingly to provide to the holders of Greyhound Stock and Iris Stock the same economic effect as contemplated by this Agreement prior to such event.

(b) Notwithstanding anything to the contrary set forth in this Agreement, in no event shall: (i) the percentage obtained by dividing (A) the sum of (i) the shares of Parent Preferred Stock issued to the Iris Stockholders pursuant to this Article II and (ii) the Reinvestment Shares that are shares of Parent Preferred Stock, by (B) the sum of (i) the total number of shares of Parent Preferred Stock outstanding immediately following the Effective Time and (ii) the Parent Preferred Stock issuable upon outstanding options, warrants and other rights exercisable therefor (including the Greyhound Substitute Options and excluding the Greyhound Substitute SAR), assuming conversion or exercise thereof, outstanding immediately following the Effective Time exceed the Iris Preferred Percentage; (ii) the percentage obtained by dividing (A) the sum of (i) the shares of Parent Common Stock issued to the Iris Stockholders pursuant to this Article II and (ii) the Reinvestment Shares that are shares of Parent Common Stock, by (B) the sum of (i) the total number of shares of Parent Common Stock outstanding immediately following the Effective Time and (ii) the Parent Common Stock issuable upon outstanding options, warrants and other rights exercisable therefor (including the Greyhound Substitute Options and excluding the Greyhound Substitute SAR), assuming conversion or exercise thereof, outstanding immediately following the Effective Time exceed the Iris Common Percentage; or (iii) the sum of the Iris Class A Cash Merger Consideration, Iris Class B Cash Merger Consideration, Iris Class C Cash Merger Consideration and Iris Class L Cash Merger Consideration payable with respect to Iris Capital Stock pursuant to this Article II exceed the Aggregate ▇▇▇▇ ▇▇▇▇ Merger Consideration.

SECTION 2.08. Dissenting Shares. (c) Notwithstanding any provision of this Agreement to the contrary and to the extent available under the DGCL, the Greyhound Shares and Iris Shares that are outstanding immediately prior to the Effective Time or Initial Effective Time, as applicable, and that are held by stockholders who shall have neither voted in favor of the Greyhound Merger or Iris Merger, as applicable, nor consented thereto in writing and who shall have demanded properly in writing appraisal for such Greyhound Shares or Iris Shares, as applicable, in accordance with Section 262 of the DGCL (collectively, the “Dissenting Shares”) shall not be converted into, or represent the right to receive, the applicable merger consideration set forth in Section 2.01 or Section 2.02. Such stockholders shall be entitled to receive payment of the appraised value of such Greyhound Shares or Iris Shares, as applicable, held by them in accordance with the provisions of such Section 262, except that all Dissenting Shares held by stockholders who shall have failed to perfect or who effectively shall have withdrawn or lost their rights to appraisal of such Greyhound Shares or Iris Shares, as applicable, under such Section 262 shall thereupon be deemed to have been converted into, and to have become exchangeable for, as of the Effective Time or Initial Effective Time, as applicable, the right to receive the applicable merger consideration set forth in Section 2.01 or Section 2.02, without any interest thereon, upon surrender, in the manner provided in Section 2.03, of the certificate or certificates that formerly evidenced such Greyhound Shares or Iris Shares, as applicable.

(b) Each Party shall give the other Parties prompt notice of any demands for appraisal received by such Party, withdrawals of such demands, and any other instruments

served pursuant to the DGCL and received by such Party. Iris shall give Greyhound the opportunity to direct all negotiations and proceedings with respect to demands for appraisal under the DGCL. Iris shall not, except with the prior written consent of Greyhound, make any payment with respect to any demands for appraisal or offer to settle or settle any such demands.

SECTION 2.09. Escrow. Notwithstanding Section 2.02, an amount of cash equal to the Escrow Amount shall be withheld from the Aggregate ▇▇▇▇ ▇▇▇▇ Merger Consideration payable to the Iris Minority Holders in respect of their Iris Capital Stock pursuant to Section 2.02 and the Iris Option Payment Amount payable to the holders of Iris Stock Options pursuant to Section 2.05(b). Pursuant to an escrow agreement to be entered into on the Closing Date by and among Parent, the Iris Stockholder Representative and U.S. Bank National Association or another financial institution that is reasonably acceptable to Parent and the Iris Stockholder Representative, as escrow agent (including any successor in such capacity, the “Escrow Agent”), in the form attached hereto as Exhibit C, subject to any administrative changes as may be required by the Escrow Agent (the “Escrow Agreement”), Parent and the Iris Stockholder Representative shall appoint the Escrow Agent to hold and disburse the Escrow Funds as provided below. As promptly as practicable after the Effective Time, Parent shall deposit, or shall cause to be deposited, with the Escrow Agent the Escrow Amount (together with any interest or other earnings thereon, the “Escrow Funds”) by wire transfer of immediately available funds. The Escrow Funds shall be held by the Escrow Agent in segregated accounts to serve as a source of payment of (x) any obligation of the Iris Minority Holders under Section 2.06(d) and (y) any indemnification obligation of the Iris Minority Holders set forth in Section 9.02. Parent and the Iris Stockholder Representative shall instruct the Escrow Agent to disburse the Escrow Funds as follows:

(i) Promptly following the determination of the Final Working Capital and the satisfaction of any payment obligations under 2.06(d) (the "Working Capital Release Date"), Parent and the Iris Stockholder Representative shall direct the Escrow Agent to release to the Exchange Agent (for further distribution to the Iris Minority Holders) a portion of the Escrow Fund equal to the excess, if any, of the Working Capital Escrow Amount over the amount, if any, distributed or disbursed by the Escrow Agent in satisfaction of the obligations of the Iris Minority Holders under Section 2.06(d).

(ii) On the twelve month anniversary of the Closing Date (the "Final Release Date"), Parent and the Iris Stockholder Representative shall direct the Escrow Agent to release to the Exchange Agent (for further distribution to the Iris Minority Holders) a portion of the Escrow Fund equal to the excess, if any, of the remaining amount of the Escrow Fund over the sum of (a) all amounts theretofore distributed or disbursed by the Escrow Agent (including any amounts distributed or disbursed by the Escrow Agent in satisfaction of the obligations of the Iris Minority Holders under Section 2.06(d)), and (b) the aggregate amount of Losses specified in any then unresolved good faith Claims made by Parent pursuant to Section 9.02. To the extent that, on the Final Release Date, any amount has been reserved and withheld from distribution from the Escrow Fund on such date on account of an unresolved claim for indemnification and, subsequent to such Final Release Date, such Claim is resolved, the parties shall immediately direct the Escrow Agent to release (A) to Parent the amount of Losses, if any, due in respect of such Claim as finally determined, and (B) to the Exchange Agent (for further distribution to the Iris

Minority Holders) an amount equal to the excess, if any, of the amount theretofore reserved and withheld from distribution in respect of such Claim over the payment, if any, made pursuant to the foregoing clause (A).

ARTICLE III

REPRESENTATIONS AND WARRANTIES OF IRIS

Except as set forth in the Iris Disclosure Schedule that has been prepared by Iris and delivered by Iris to Greyhound in connection with the execution and delivery of this Agreement (the “Iris Disclosure Schedule”) (which Iris Disclosure Schedule shall be arranged in sections corresponding to the numbered and lettered sections of this Article III, and any information disclosed in any section of the Iris Disclosure Schedule shall be deemed to be disclosed only for purposes of the corresponding section of this Article III, unless it is readily apparent that the disclosure contained in such section of the Iris Disclosure Schedule contains enough information regarding the subject matter of other representations and warranties contained in this Article III as to reasonably qualify or otherwise reasonably apply to such other representations and warranties), Iris and Parent hereby represent and warrant to Greyhound that:

SECTION 3.01. Corporate Organization. (a) Each of Iris and each subsidiary of Iris (each an “Iris Subsidiary”) is duly organized, validly existing and in good standing under the laws of the jurisdiction of its incorporation and has the requisite power and authority and all necessary governmental approvals to own, lease and operate its properties and to carry on its business as it is now being conducted, except where the failure to be so organized, existing or in good standing or to have such power, authority and governmental approvals could not reasonably be expected, individually or in the aggregate, to prevent or materially delay consummation of the Mergers and the Transactions, and could not reasonably be expected, individually or in the aggregate, to have an Iris Material Adverse Effect (as hereinafter defined). Each of Iris and each Iris Subsidiary is duly qualified or licensed as a foreign corporation to do business, and is in good standing, in each jurisdiction where the character of the properties owned, leased or operated by it or the nature of its business makes such qualification or licensing necessary, except for such failures to be so qualified or licensed and in good standing that could not reasonably be expected, individually or in the aggregate, to prevent or materially delay consummation of any of the Transactions or otherwise prevent or materially ▇▇▇▇▇ ▇▇▇▇ from performing its obligations under this Agreement and could not reasonably be expected, individually or in the aggregate, to have an Iris Material Adverse Effect.

(b) A true and complete list of all the Iris Subsidiaries, together with the jurisdiction of incorporation of each Iris Subsidiary and the percentage of the outstanding capital stock of each Iris Subsidiary owned by Iris and each other Iris Subsidiary, is set forth in Section 3.01(b) of the Iris Disclosure Schedule.

Except as contemplated hereby and except for any agreements to be terminated on or prior to the Effective Time, there are no voting trusts, proxies, or other agreements or understandings with respect to the Iris Capital Stock. All outstanding shares of

▇▇

None of the Iris Plans provides for or promises retiree medical, disability or life insurance benefits to any current or former employee, officer or director of Iris or any Iris Subsidiary (other than coverage mandated by applicable law).

(c) Each Iris Plan is now and always has been operated in all material respects in accordance with its terms and the requirements of all applicable Laws, including, without limitation, ERISA and the Code.

Neither the IRS nor any other United States or non-United States taxing authority or agency is now asserting or, to the knowledge of Iris, threatening to assert, against Iris or any Iris Subsidiary any material deficiency or claim for any Taxes or interest thereon or penalties in connection therewith. Neither Iris nor any Iris Subsidiary has granted any waiver of any statute of limitations with respect to, or any extension of a period for the assessment of, any Tax deemed material.

(g) To the knowledge of Greyhound, no person is engaging in any activity that infringes, misappropriates or otherwise violates any Greyhound Owned Intellectual Property in any material respect.

(h) Neither Greyhound or any Greyhound Subsidiary is bound by or subject to any contract or agreement under which the execution of this Agreement or the consummation of the Transactions will result in (i) the grant of any license under, or the creation of any Lien on, any Intellectual Property that is owned by or licensed to Greyhound or any Greyhound Subsidiary, which such party was not bound by or subject to prior to the Closing, (ii) Greyhound or any Greyhound Subsidiary being bound by or subject to any non-compete or licensing obligation, covenant not to ▇▇▇, or other material restriction on the operation or scope of its business, which such party was not bound by or subject to prior to the Closing, or (iii) Greyhound or any Greyhound Subsidiary being obligated to (A) pay any royalties, honoraria, fees or other payments to any person in material excess of those payable by such party prior to the Closing, or (B) provide or offer any discounts or other reduced payment obligations to any person in material excess of those provided to such person prior to the Closing.

SECTION 4.14. Taxes. Greyhound and the Greyhound Subsidiaries have filed all United States federal, state, local and non-United States Tax returns and reports required to be filed by them and have paid and discharged all Taxes required to be paid or discharged, other than such payments as are being contested in good faith by appropriate proceedings. All such Tax returns are true, accurate and complete in all material respects. Neither the IRS nor any other United States or non-United States taxing authority or agency is now asserting or, to the knowledge of Greyhound, threatening to assert, against Greyhound or any Greyhound Subsidiary any material deficiency or claim for any Taxes or interest thereon or penalties in connection therewith. Neither Greyhound nor any Greyhound Subsidiary has granted any waiver of any statute of limitations with respect to, or any extension of a period for the assessment of, any Tax deemed material. The accruals and reserves for Taxes reflected in the Most Recent Greyhound Balance Sheet are adequate to cover all Taxes accruable through such date (including interest and penalties, if any, thereon) in accordance with GAAP. There are no Tax liens upon any property or assets of Greyhound or any of the Greyhound Subsidiaries except liens for current Taxes not yet due. Neither Greyhound nor any of the Greyhound Subsidiaries is currently required to include in income any adjustment pursuant to Section 481 of the Code by reason of a voluntary change in accounting method initiated by Greyhound or any of the Greyhound Subsidiaries, and the IRS has not initiated or proposed any such adjustment or change in accounting method, in either case which adjustment or change could reasonably be expected to be material. Neither Greyhound nor any Greyhound Subsidiary has been a “distributing corporation” or a “controlled corporation” in a distribution intended to qualify under Section 355 of the Code within the past five years. To the knowledge of Greyhound, neither Greyhound nor any of its Affiliates has taken or agreed to take any action that would prevent the Mergers from qualifying as exchanges under the provisions of Section 351 of the Code. Greyhound is not aware of any agreement, plan or other circumstance that would prevent the Mergers from qualifying as exchanges under the provisions of Section 351 of the Code.

Prior to the Initial Effective Time, Iris shall take all actions necessary or desirable to terminate its 401(k) Plan (the “Iris 401(k) Plan”), effective not later than the day immediately preceding the Initial Effective Time, and to amend the Iris 401(k) Plan to allow for participants thereunder to rollover loans under the Iris 401(k) Plan to an eligible retirement plan that permits such rollovers.

The Parties agree that, notwithstanding any provision of this Agreement to the contrary, the payments provided for in this Section 8.03 shall be the sole and exclusive remedies, at law or in equity, or otherwise, of the Parties against the other Parties or any of their respective former, current or future general or limited partners, shareholders, managers, members, directors, officers, employees or Affiliates or their Representatives (collectively, with respect to any Party, such Party’s “Related Parties”) for any loss suffered as a result of the failure of the Mergers to be consummated or for a breach or failure to perform hereunder or otherwise (with respect to any Party, such Party’s “Damages”) and such remedies shall be limited to the sums stipulated in this Section 8.03 regardless of the circumstances giving rise to such termination.

(g) Notwithstanding anything herein to the contrary: (i) the maximum aggregate liability of a Party for the Damages of any other Party (inclusive of the Termination Fee, if any, payable by such first Party to such second Party), shall be limited to an amount equal to the Termination Fee, if any, payable by such first Party to such second Party plus any amounts that become payable by such first Party to such second Party under Section 8.03(f) (such first Party’s, “Liability Limitation” with respect to such second Party); (ii) in no event shall any Party or any of its respective Affiliates seek from another Party (x) any Damages in excess of the Liability Limitation of the second party vis-a-vis the first party or (y) any other recovery, judgment, or damages of any kind, including equitable relief or consequential, indirect, or punitive damages, against Related Parties of such second Party in connection with this Agreement or the Merger; and (iii) each Party hereby acknowledges and agrees that it has no right of recovery against, and no personal liability shall attach to, in each case with respect to such Party’s Damages, any other Party’s Related Parties, whether by or through attempted piercing of the corporate veil, by or through a claim by or on behalf of such second Party against

any Related Party of such second Party, by the enforcement of any assessment or by any legal or equitable proceeding, by virtue of any statute, regulation or applicable law, or otherwise, except for such first Party’s right, if any, to recover a Termination Fee or Damages from such second Party or, if applicable, subject to the Liability Limitation of such second Party vis-a-vis such first Party, from such second Party.

SECTION 8.04. Amendment. Subject to applicable Law, this Agreement may be amended by the Parties by action taken by or on behalf of their respective Boards of Directors at any time prior to the Effective Time; provided, however, that, after the approval and adoption of this Agreement and the Transactions by the stockholders of Greyhound or Iris, no amendment may be made that would reduce the amount or change the type of consideration into which each Greyhound Share or Iris Share, respectively, shall be converted upon consummation of the Merger, without the further approval or adoption of such amendment by the stockholders of Greyhound or Iris, as applicable. This Agreement may not be amended except by an instrument in writing signed by each of the Parties.

SECTION 8.05. Waiver. At any time prior to the Effective Time, any Party may (a) extend the time for the performance of any obligation or other act of any other Party, (b) waive any inaccuracy in the representations and warranties of any other Party contained herein or in any document delivered pursuant hereto and (c) waive compliance with any agreement of any other Party or any condition to its own obligations contained herein.

ARTICLE IX

INDEMNIFICATION

SECTION 9.01. Survival of Representations and Warranties. The representations and warranties of the Parties contained in this Agreement shall survive the Closing for a period of twelve (12) months after the Closing; provided, however, that the representations and warranties in Section 3.03(a) (Capitalization), 3.04 (Authority Relative to this Agreement), Section 3.21 (Brokers), Section 4.03(a) (Capitalization), 4.04 (Authority Relative to this Agreement), and Section 4.21 (Brokers) (all of such representations and warranties the “Special Representations”) shall survive until fifteen (15) days after the last day of the applicable statute of limitations period relating thereto; provided further that any claim made with reasonable specificity by the Party seeking to be indemnified within the time periods set forth in this Section 9.01 shall survive until such claim is finally and fully resolved.

SECTION 9.02. Indemnification by Iris Stockholders. From and after the Initial Effective Time, each Iris Stockholder and, solely with respect to any indemnification obligation that is subject to the Cap Amount, each recipient of a portion of the Iris Option Payment Amount as of the Initial Effective Time (the “Iris Indemnifying Parties”), on a several and not joint basis (in proportion to their respective Pro Rata Portion with respect to indemnification obligations that are subject to the Cap Amount and in proportion to their respective Shareholder Pro Rata Portion with respect to any other indemnification obligation), hereby agrees to indemnify and hold Parent and its Subsidiaries and their respective officers, directors, employees, agents,

successors and assigns (each, a “Parent Indemnified Party”) harmless for and against all losses, damages, claims, costs and expenses, interest, awards, judgments and penalties (including reasonable attorneys’ and consultants’ fees and expenses) (hereinafter, a “Loss”) suffered or incurred by any such Parent Indemnified Party arising out of or resulting from (i) the breach of (A) any representation or warranty made by Iris contained in this Agreement or (B) any covenant made by Iris contained in this Agreement other than any such breach of a covenant that is material, intentional and knowing (i.e. the fact that such action constitutes a breach of a covenant is within the knowledge of Iris at the time of such breach), and (ii) any Iris Excluded Liability Matters.

SECTION 9.03. Indemnification by Parent. From and after the Effective Time, Parent (the “Parent Indemnifying Party”) hereby agrees to indemnify and hold the Iris Stockholders and their officers, directors, employees, agents, successors and assigns (each, an “Iris Indemnified Party”) harmless for and against any and all Losses suffered or incurred by any such Iris Indemnified Party arising out of or resulting from: (i) (i) the breach of (A) any representation or warranty made by Greyhound contained in this Agreement or (B) any covenant made by Greyhound contained in this Agreement other than any such breach of a covenant that is material, intentional and knowing (i.e. the fact that such action constitutes a breach of a covenant is within the knowledge of Greyhound at the time of such breach), and (ii) Parent Excluded Liability Matters.

SECTION 9.04. Indemnification Procedures. (a) No claim may be asserted nor may any Action be commenced against any Indemnifying Party, unless written notice of such claim or action is received by Parent, in the case of a claim or action in which indemnification may be sought from the Parent, and the Iris Stockholder Representative, in the case of a claim or action in which indemnification may be sought from the Iris Indemnifying Parties, describing in reasonable detail the facts and circumstances with respect to the subject matter of such claim or Action on or prior to the date on which the representation, warranty, covenant or agreement on which such claim or Action is based ceases to survive as set forth in Section 9.01, irrespective of whether the subject matter of such claim or action shall have occurred before or after such date.

(b) Pursuant to the terms of the Escrow Agreement, the Escrow Fund shall be available to compensate the Parent Indemnified Parties for any claims by such parties against the Iris Minority Holders for any Losses suffered or incurred by them and for which they are entitled to recovery under this Article VIII.

(c) Notwithstanding anything to the contrary contained in this Agreement: (i) the Iris Indemnifying Parties shall not be liable for any claim for indemnification pursuant to Section 9.02(i) and the Parent Indemnifying Party shall not be liable for any claim for indemnification pursuant to Section 9.03(i), unless and until the aggregate amount of indemnifiable Losses which may be recovered pursuant to Section 9.02(i) or Section 9.03(i), as applicable, equals or exceeds $1,750,000, after which such Indemnifying Party shall be liable only for those Losses in excess of $1,750,000; (ii) the maximum amount of indemnifiable Losses which may be recovered from the Iris Indemnifying Parties arising out of or resulting from the causes set forth in Section 9.02(i), and the maximum amount of indemnifiable Losses which may be recovered from the Parent Indemnifying Party arising out of or resulting from the causes set forth in or Section 9.03(i), shall each be an amount equal to the Cap Amount; (iii) no Party shall have

any liability under any provision of this Agreement for any punitive, incidental, consequential, special or indirect damages, including loss of future revenue or income, or loss of business reputation or opportunity relating to the breach or alleged breach of this Agreement; and (iv) no Iris Indemnifying Party shall have any liability under any provision of this Agreement or as a result of the Transactions in excess of such Iris Indemnifying Party’s pro rata portion of the Aggregate Iris Merger Consideration (and in the form thereof, whether cash or Parent equity) plus, in the case of GGC, the amount of any Transaction Fees paid to GGC Administration, LLC or its Affiliates and in the case of Cerberus, the amount of any Transaction Fees paid to Cerberus Partners, L.P. or its Affiliates.

(d) Any indemnification of the Parent Indemnified Parties pursuant to Section 9.02(i) with respect to the first $5,000,000 of payments pursuant thereto shall be effected by cancellation (based on identical proportions of Parent Preferred Stock and Parent Common Stock to the proportions in which such shares were issued to the applicable Iris Indemnifying Party as part of the merger consideration, and at the Parent Common Stock Value or Parent Preferred Stock Value, as applicable) of a portion of the shares of Parent Capital Stock issued to the Iris Indemnifying Parties. Any indemnification of the Iris Indemnified Parties pursuant to Section 9.03(i) with respect to the first $5,000,000 of payments pursuant thereto shall be effected by delivery (based on identical proportions of Parent Common Stock and Parent Preferred Stock in which such shares were issued to the applicable Iris Indemnified Party as part of the merger consideration, and at the Parent Common Base Amount or Parent Preferred Base Amount, as applicable) of additional Parent Capital Stock. Any other indemnification of the Iris Indemnified Parties, and any other indemnification of the Parent Indemnified Parties, shall be effected in cash; provided, however, that any such indemnification of the Parent Indemnified Parties shall be effected in the manner set forth in the first sentence of this Section 9.04(d) (disregarding the $5,000,000 cap therein) with respect to (i) any Iris Indemnifying Party that has no further obligation to make cash payments pursuant to the parenthetical set forth in Section 9.04(c)(iv) (but which still has remaining capacity pursuant to such parenthetical to effect payments by means of the cancellation of stock) and (ii) GGC and/or Cerberus, as applicable, to the extent that GGC or Cerberus, as applicable, has remaining capacity pursuant to such parenthetical to effect payments by means of the cancellation of stock but has no capacity to effect payment in the form of cash (ignoring, solely for the purpose of this clause (ii), the GGC or Cerberus-related Transaction Fees, as the case may be) (it being understood, for avoidance of doubt, that neither GGC nor Cerberus shall have any cash indemnification obligation arising out of the inclusion of Transaction Fees in the limitation set forth in Section 9.04(c)(iv) unless and until all of the Parent Capital Stock issued to GGC or Cerberus, as applicable, shall have been cancelled in respect of its indemnification obligations hereunder).

(e) For all purposes of this Article IX, “Losses” shall be adjusted for, and net of (i) any insurance or other recoveries actually paid to the Indemnified Party or its Affiliates in connection with the facts giving rise to the right of indemnification (net of the amount of any premium increases and recovery costs from any amounts recovered by the Indemnified Party or its Affiliates for purposes of adjustment to the amount of any Losses) and (ii) any Tax benefit realized by the Indemnified Party or its Affiliates arising in connection with the accrual, incurrence or payment of any such Losses.

SECTION 9.05. Notice of Loss; Third Party Claims. (a) An Iris Indemnified Party shall give Parent and a Parent Indemnified Party shall give the Iris Stockholder Representative notice of any matter which such Indemnified Party has determined has given or could give rise to a right of indemnification under this Agreement, promptly following such determination, stating the amount of the Loss, if known, and method of computation thereof, and containing a reference to the provisions of this Agreement in respect of which such right of indemnification is claimed or arises; provided, however, that the failure to provide such notice shall not release the applicable Indemnifying Party from any of their obligations under this Article IX except to the extent that such failure results in a detriment to the applicable Indemnifying Party.

(b) If an Indemnified Party shall receive notice of any Action, audit, claim, demand or assessment (each, a “Third Party Claim”) against it which may give rise to a claim for Loss under this Article IX, within 30 days of the receipt of such notice, the Indemnified Party, if an Iris Indemnified Party, shall give Parent, and if a Parent Indemnified Party, shall give Stockholder Representative, notice of such Third Party Claim; provided, however, that the failure to provide such notice shall not release the applicable Indemnifying Party from any of their obligations under this Article IX except to the extent that such failure results in a detriment to applicable Indemnifying Party. Parent shall control the defense of any Third Party Claim against it, and shall be entitled to assume and control the defense of any Third Party Claim against another Indemnified Party at Parent’s expense and through counsel of its choice if it gives notice of its intention to do so to the Iris Stockholder Representative within 15 days of the receipt of notice of such Third Party Claim. If Parent elects to undertake any such defense against a Third Party Claim, the Indemnified Party may participate in such defense at its own expense. The Indemnified Party shall cooperate with Parent in such defense and make available to Parent, at such Indemnifying Party’s expense, all witnesses, pertinent records, materials and information in the Indemnified Party’s possession or under the Indemnified Party’s control relating thereto as is reasonably required by the Indemnifying Party. If Parent elects to direct the defense of any such claim or proceeding, the Indemnified Party shall not pay, or permit to be paid, any part of such Third Party Claim unless Parent consents in writing to such payment or unless Parent withdraws from the defense of such Third Party Claim liability or unless a final judgment from which no appeal may be taken by or on behalf of the applicable Indemnifying Party is entered against the Indemnified Party for such Third Party Claim. Parent shall have the right in its sole discretion to settle, any such Third Party Claim so long as such settlement includes an unconditional release of the Indemnified Parties; provided, however, that except with the prior written consent of the Iris Stockholder Representative, no settlement of any such Third Party Claim shall be solely determinative of the amount of Losses relating to such matter.

SECTION 9.06. Remedies. The Parties acknowledge and agree that following the Closing, the indemnification provisions of Section 9.02 and Section 9.03 shall be the sole and exclusive remedies of the Greyhound Stockholders and Iris Stockholders for any breach of the representations and warranties in this Agreement and for any failure to perform and comply with any covenants and agreements in this Agreement or in any way relating to the Transactions (whether based on breach of contract, tort or any other legal theory); provided, however, that nothing in this Agreement shall be deemed to prevent or restrict the bringing or maintenance of any claim or Action to the extent that the same shall have been the result of intentional or knowing fraud or intentional misrepresentation by any such person.

SECTION 9.07. Iris Stockholder Representative. (a) Each of the Iris Stockholders (by virtue of their adoption of this Agreement and/or acceptance of its portion of the Aggregate Iris Merger Consideration) hereby appoints CCG Investment Fund, L.P. and Cerberus Institutional Partners, L.P. as its agent and attorney-in-fact, as the Iris Stockholder Representative for and on behalf of the Iris Stockholders to give and receive notices and communications, to authorize payment to Parent Indemnified Parties from the Escrow Account in satisfaction of claims by any Parent Indemnified Party, to agree to, negotiate, enter into settlements and compromises of, and demand arbitration and comply with orders of courts and awards of arbitrators with respect to claims, and to take all other actions that are either (i) necessary or appropriate in the judgment of the Iris Stockholder Representative for the accomplishment of the foregoing or (ii) specifically mandated by the terms of this Agreement or the Escrow Agreement. Such agency may be changed by the Iris Stockholders from time to time upon not less than thirty (30) days prior written notice to Parent; provided, however, that the Iris Stockholder Representative may not be removed unless each of the Iris Indemnifying Parties consent. The Iris Stockholder Representative may resign upon thirty (30) days prior written notice to Parent and the Iris Stockholders. A vacancy in the position of the Iris Stockholder Representative may be filled by the holders of a majority in interest of the shares of Parent Capital Stock held by the Iris Indemnifying Parties. No bond shall be required of the Iris Stockholder Representative, and the Iris Stockholder Representative shall not receive any compensation for its services. Notices or communications to or from the Iris Stockholder Representative shall constitute notice to or from the Iris Stockholders. Any action taken by the Stockholder Representative hereunder shall require the joint written consent of each of CCG Investment Fund, L.P. and Cerberus Institutional Partners, L.P., and references to the Stockholder Representative herein shall be construed accordingly.

(b) In connection with this Agreement, the Escrow Agreement, and any instrument, agreement or document relating hereto, and in exercising or failing to exercise all or any of the powers conferred upon the Iris Stockholder Representative hereunder (i) the Iris Stockholder Representative shall incur no responsibility whatsoever to any Iris Stockholders by reason of any error in judgment or other act or omission performed or omitted hereunder, or in connection with the Escrow Agreement or any such other agreement, instrument or document, excepting only responsibility for any act or failure to act which represents willful misconduct, and (ii) the Iris Stockholder Representative shall be entitled to rely on the advice of counsel, public accountants or other independent experts experienced in the matter at issue, and any error in judgment or other act or omission of the Iris Stockholder Representative pursuant to such advice shall in no event subject the Iris Stockholder Representative to liability of any Iris Stockholder. Each Iris Indemnifying Party shall indemnify and reimburse, pro rata based upon such Iris Indemnifying Party’s Pro Rata Portion, the Iris Stockholder Representative against all losses, damages, liabilities, claims, obligations, costs and expenses, including reasonable attorneys’, accountants’ and other experts’ fees and the amount of any judgment against them, of any nature whatsoever (including, but not limited to, any and all expense whatsoever reasonably incurred in investigating, preparing or defending against any litigation, commenced or threatened or any claims whatsoever), arising out of or in connection with any act or omission of the Iris Stockholder Representative hereunder or under the Escrow Agreement. The foregoing indemnification shall not apply only in the event of any action or proceeding which finally adjudicates the liability of the Iris Stockholder Representative hereunder for its willful misconduct. In the event of any indemnification hereunder, upon written notice from the Iris

Stockholder Representative to the Iris Indemnifying Parties, each Iris Indemnifying Party shall promptly deliver to the Iris Stockholder Representative full payment of its ratable share of the amount of such deficiency based upon such Iris Indemnifying Party’s Pro Rata Portion. All of the indemnities, immunities and powers granted to the Iris Stockholder Representative under this Agreement shall survive the Effective Time and /or any termination of this Agreement.

(c) A decision, act, consent or instruction of the Iris Stockholder Representative, shall constitute a decision of the Iris Stockholders and shall be final, binding and conclusive upon the Iris Stockholders; and the Escrow Agent and the Parties may rely upon any such decision, act, consent or instruction of the Iris Stockholder Representative as being the decision, act, consent or instruction of the Iris Stockholders. The Parties are hereby relieved from any liability to any person for any acts done by them in accordance with such decision, act, consent or instruction of the Iris Stockholder Representative.
