In making its calculation of the Final Adjusted Net Asset Value, the Arbitrator may consider only those items or amounts in the Proposed Final Adjusted Net Asset Value as to which Purchaser has disagreed as set forth in the Dispute Notice. The Arbitrator’s determination of any disputed items or amounts and its calculation of the Final Adjusted Net Asset Value must be within the range of the amount shown on the Proposed Final Adjusted Net Asset Value and the amount shown on the Dispute Notice. The Arbitrator shall deliver to Purchaser and Sellers, as promptly as practicable (but not more than 45 days from the date of engagement of the Arbitrator), a report setting forth its Final Adjusted Net Asset Value calculation. The Arbitrator’s report will be final and binding upon Purchaser and Sellers. The fees, costs and expenses of the Arbitrator shall be evenly split between Purchaser and Sellers. The Adjusted Net Asset Value agreed upon by Sellers and Purchaser (or deemed accepted by Purchaser) under this subsection, as adjusted, if necessary based on a decision by the Arbitrator hereunder, is referred to herein as the “ Final Adjusted Net Asset Value .”

T ERMINATION , A MENDMENT AND W AIVER

9.1 Termination .

At any time prior to the Closing, this Agreement may be terminated and the Purchase abandoned by authorized action taken by the terminating party:

(a) by mutual written consent of Sellers and Purchaser;

(b) by either Purchaser or Sellers, if the Closing shall not have occurred on or before January 27, 2012 or such other date that Purchaser and Sellers may agree upon in writing (the “ Termination Date ”); provided , however , that the right to terminate this Agreement under this clause (b) of Section 9.1 shall not be available to any party whose breach of this Agreement has resulted in the failure of the Closing to occur on or before the Termination Date;

(c) by either Purchaser or Sellers, if any permanent injunction or other order of a Governmental Entity of competent authority preventing the completion of the Purchase shall have become final and nonappealable;

(d) by Purchaser, if Sellers shall have materially breached any representation, warranty, covenant or agreement contained herein and such breach shall not have been cured within 30 days after receipt by Sellers from Purchaser of written notice of such breach ( provided , however , that no such cure period shall be available or applicable to any such breach which by its nature cannot be cured) and if not cured within the timeframe above and at or prior to the Closing, such breach would result in the failure of any of the conditions set forth in Section 8.1 or Section 8.3 to be satisfied; or

(e) by Sellers, if Purchaser shall have materially breached any representation, warranty, covenant or agreement contained herein and such breach shall not have been cured within 30 days after receipt by Purchaser from Sellers of written notice of such breach ( provided , however , that no such cure period shall be available or applicable to any such breach which by its nature cannot be cured) and if not cured within the timeframe above and at or prior to the Closing, such breach would result in the failure of any of the conditions set forth in Section 8.1 or Section 8.2 to be satisfied.

9.2 Effect of Termination .

In the event of termination of this Agreement as provided in Section 9.1 , this Agreement shall forthwith become void and there shall be no liability or obligation on the part of Purchaser, Sellers or the Company; provided , however , that (a) the provisions of this Section 9.2 (Effect of Termination) and Article XI (General Provisions) shall remain in full force and effect and survive any termination of this Agreement, and (b) nothing herein shall relieve any party hereto from liability in connection with any willful breach of such party’s representations, warranties, covenants or agreements contained herein.

51

9.3 Amendment .

Subject to the provisions of applicable Legal Requirements, the parties hereto may amend this Agreement at any time pursuant to an instrument in writing signed on behalf of each of the parties hereto.

9.4 Waiver . A waiver of any default, breach or non-compliance under this Agreement shall not be effective unless in writing and signed by the Party to be bound by the waiver.

The waiver by a Party of any default, breach or non-compliance under this Agreement will not operate as a waiver of that Party’s rights under this Agreement in respect of any continuing or subsequent default, breach or non-observance (whether of the same or any other nature).

ARTICLE X

The parties acknowledge that the time periods set forth in this Article X and elsewhere in this Agreement for the assertion of claims and notices under this Agreement are the

52

result of arms’-length negotiation between the parties and that they intend for the time periods to be enforced as agreed by the parties. The parties further acknowledge that the time periods set forth in this Article X and elsewhere in the Agreement may be shorter than otherwise provided by applicable Legal Requirements and that the representations and warranties set forth in this Agreement shall in no event be affected by any investigation, inquiry or examination made for or on behalf of any party or the acceptance by any party of any certificate hereunder.

10.2 Indemnification by Sellers . Each Seller, severally and not jointly (subject to Section 10.4(f)), shall hold harmless and indemnify Purchaser and its controlled affiliates, and each of their respective officers, directors, employees, successors and assigns (each of the foregoing being referred to individually as a “ Purchaser Indemnified Person ” and collectively as “ Purchaser Indemnified Persons ”) from and against any and all losses, liabilities, damages, fees, obligations, judgments, settlements, interest, penalties, fees, Proceedings, costs and expenses, including costs of investigation and defense and reasonable fees and expenses of lawyers, experts and other professionals (collectively, “ Indemnifiable Damages ”), whether or not due to a third-party claim, arising out of, or resulting from (and without duplication):

(a) any breach of any representation or warranty made by the Company or Sellers in (i) this Agreement, (ii) any certificate delivered to Purchaser by Sellers in connection with this Agreement, or (iii) any document or agreement between the Company or the Sellers and the Purchaser delivered to Purchaser in connection with this Agreement;

(b) any breach of the covenants or agreements made by the Company or Sellers in (i) this Agreement, (ii) any certificate delivered to Purchaser by Sellers in connection with this Agreement, or (iii) any document or agreement between the Company or the Sellers and the Purchaser delivered to Purchaser in connection with this Agreement;

(c) Pre-Closing Taxes ; and

(d) any Indemnifiable Transaction Expenses.

10.3 Indemnification by Purchaser . The Purchaser shall hold harmless and indemnify the Sellers, and each of their respective officers, directors, employees, successors and assigns (each of the foregoing being referred to individually as a “ Seller Indemnified Person ” and collectively as “Sellers Indemnified Persons”, and together with the Purchasers Indemnified Persons, the “ Indemnified Persons ”) from and against any and all Indemnifiable Damages, whether or not due to a third-party claim, arising out of, or resulting from (and without duplication):

(a) any breach of any representation or warranty made by the Purchaser in this Agreement or any certificate or other document or agreement delivered to the Company or Sellers by the Purchaser in connection with this Agreement; or

(b) any breach of the covenants or agreements made by the Purchaser in this Agreement or any certificate or other document or agreement delivered to the Company or Sellers by the Purchaser in connection with this Agreement.

53

10.4 Limitations; Exclusive Remedy . The entitlement of any Indemnified Persons to be indemnified pursuant to this Article X shall be subject to each of the following principles or qualifications:

(a) No claim for the recovery of Indemnifiable Damages pursuant to Section 10.2 or 10.3 may be asserted by any Indemnified Person after the expiration of the applicable Survival Period; provided , however , that claims first asserted in writing prior to such expiration in a Claim Notice shall survive expiration of the applicable survival period.

(b) No claim for Indemnifiable Damages shall be made pursuant to Section 10.2(a) or 10.3(a) unless the aggregate of all Indemnifiable Damages for which claims under such Section 10.2(a) or 10.3(a) , as applicable, are made hereunder by the Purchaser Indemnified Persons or the Sellers Indemnified Persons, as applicable, exceeds $540,000 (the “ Threshold Amount ”). If the total amount of Indemnifiable Damages under such Section 10.2(a) or 10.3(a) , as applicable, exceeds the Threshold Amount, then the applicable Indemnified Persons shall be entitled to be indemnified against and compensated and reimbursed for all Indemnifiable Damages including the Threshold Amount. The Threshold Amount shall not apply to claims made pursuant to Section 10.2(a) or 10.3(a) based on fraud, breaches of the Fundamental Representations, or breach of the representations and warranties set forth in Section 4.23 with respect to collectibility of the Accounts Receivable. The foregoing notwithstanding, no Party shall have an obligation to indemnify Indemnified Persons with respect to any individual claim for which the Indemnifiable Damages are less than $5,000; provided, however , that for any individual claim for which such $5,000 amount is exceeded, Indemnified Persons shall be entitled to the full amount of any such claim, disregarding such $5,000 threshold.

(c) The amount of any Indemnifiable Damages that are subject to indemnification under this Article X shall be calculated net of the amount of any insurance proceeds actually received by the Indemnified Persons in connection with such Indemnifiable Damages or any of the events or circumstances giving rise or otherwise related to such Indemnifiable Damages (net of all deductibles, co-payments, and all costs of collection of any such insurance proceeds). If any such insurance proceeds are received by any Indemnified Person after receiving payment or reimbursement for any Indemnifiable Damages hereunder, such Indemnified Person shall promptly cause to be paid to the indemnifying Party an amount equal to the lesser of such insurance proceeds or the amount of such Indemnifiable Damages previously paid or reimbursed.

(d) For purposes of determining the amount of any Indemnifiable Damages only, each representation and warranty shall be read without regard and without giving effect to any Materiality Qualifier contained therein (as if each such standard or qualification were deleted from such representation or warranty).

(e) With the exception of claims based upon fraud or any breach of any Fundamental Representation, recourse of Purchaser and any other Purchaser Indemnified Person for claims under Section 10.2(a) shall be limited to the right to receive from the Sellers, at the Sellers option, either (i) shares of Class A Common Stock (which do not need to be then subject to the terms of the Lock-up Agreements (“ Locked-up Shares ”)), including any Escrow Consideration, valued on a Per Share Value basis, or (ii) cash if one or more of the Sellers elect

54

to pay such Indemnifiable Damages in immediately available funds, in an aggregate amount equal to $7.5 million. For claims based on the Fundamental Representations and claims made under Sections 10.2(b), (c) or (d) , recourse of Purchaser and any other Purchaser Indemnified Person shall be limited to the right to receive from Sellers, at the Sellers option, either (i) shares of Class A Common Stock (which do not need to be Locked-up Shares), including any Escrow Consideration, valued on a Per Share Value basis, or (ii) cash if one or more of the Sellers elect to pay such Indemnifiable Damages in immediately available funds, in an aggregate amount equal to the lesser of (A) the Base Purchase Price and (B) the value (as of the date the applicable Claim Notice is first delivered by a Purchaser Indemnified Person with respect to the claim) of the then remaining Locked-up Shares, in each case calculated on a Per Share Value basis. For any claims for which one or more Sellers elect to pay in immediately available funds, the amount to be paid shall be equal to the amount of the Indemnifiable Damages. For claims based on fraud, recourse of Purchaser and any other Purchaser Indemnified Person shall be limited to the right to receive from Sellers Class A Common Stock in an amount up to the full Purchase Price paid or payable in Class A Common Stock, calculated on a Per Share Value basis.

(f) Other than for claims based upon fraud, any breach of any Fundamental Representation or, with respect to Section 4.15 (Environmental Matters), for claims made after 12 months after the Closing Date (the “ Escrow Exceptions ”), from and after the Closing, if either or both of the Sellers does not choose to satisfy their respective portion of such claims in cash then the Escrow Consideration pursuant to this Agreement and the Escrow Agreement shall be the sole and exclusive remedy of Purchaser and any other Purchaser Indemnified Persons for monetary Indemnifiable Damages for claims made pursuant to Section 10.2(a) . Notwithstanding the foregoing, any claims following the Closing based upon the Escrow Exceptions or Sections 10.2(b), (c) or (d)  for which one or more of the Sellers do not choose to satisfy their respective portion in cash must be made, first, against the Escrow Fund, and only once all amounts in the Escrow Fund have been paid out to the applicable parties or the Escrow Fund has terminated may claims be made directly against any of the Sellers. To the extent there are claims related to the Escrow Exceptions and claims not related to the Escrow Exceptions, Indemnifiable Damages not related to the Escrow Exceptions will be charged against the Escrow Fund prior to the Indemnifiable Damages related to the Escrow Exceptions. The right of Purchaser or any other Purchaser Indemnified Person to recover directly from a Seller in connection with a claim related to the Escrow Exceptions or Sections 10.2(b), (c) or (d) shall be limited to the Seller’s Pro Rata Portion of the Purchase Price and the aggregate amount of the Purchase Price actually received by such Seller, unless that particular Seller committed (or was actively involved in the commission of) any relevant fraud. The amount of any indemnification payments under this Article X that are paid out of the Escrow Consideration shall be deemed to reduce the Escrow Fund, by each Seller’s Pro Rata Portion, of any such indemnification payments.

(g) All indemnification payments made pursuant to this Article X shall be treated by the parties as adjustments to the Purchase Price (other than in relation to payment obligations of the Sellers under Section 3.5) , including for Tax purposes, unless otherwise required by applicable law.

(h) No Seller Indemnified Person shall make any claim for an indemnity or contribution or otherwise against any Company Entity in connection with any liability which any Seller or Seller Indemnified Person has or may have with respect to any representation and warranty made by any Company Entity in this Agreement or in connection with the transactions contemplated hereby.

55

10.5 Escrow Fund .

The Escrow Consideration shall be deposited by Purchaser with Canadian Stock Transfer Company Inc., as escrow agent (the “ Escrow Agent ”), such deposit to be governed by the provisions set forth herein and in the Escrow Agreement. The Escrow Consideration shall be available to compensate Purchaser or any other Purchaser Indemnified Person for Indemnifiable Damages pursuant to the indemnification obligations set forth in this Article X .

10.6 Claims .

Any Indemnified Person seeking indemnification hereunder shall promptly notify in writing (the “ Claim Notice ”) the other party or parties from whom such Indemnified Person is seeking indemnification hereunder (the “ Indemnifying Person ,” which term shall include all Indemnifying Persons if there be more than one) of any claim for Indemnifiable Damages (a “ Claim ”) with respect to which the Indemnified Person claims indemnification hereunder. Any Claim Notice delivered under this Section 10.6 shall:

(a) state that a Indemnified Person has determined in good faith that it has a claim for indemnification pursuant to this Article X ;

(b) state the amount of such Indemnifiable Damages, if reasonably known (which, in the case of Indemnifiable Damages not yet incurred, paid, reserved or accrued, may be the maximum amount reasonably anticipated by the Indemnified Person in good faith to be incurred, paid, reserved or accrued); and

(c) specifying in reasonable detail the material facts known to the Indemnified Person giving rise to such claim (based upon the information then possessed by the Indemnified Person).

No delay in providing such Claim Notice within the applicable Survival Period shall affect a Purchaser Indemnified Person’s rights hereunder, unless (and then only to the extent that) the applicable Indemnifying Persons are materially prejudiced thereby.

10.7 Third Party Claims .

(a) If any Claim against the Indemnified Person is made by or in respect of a third party (a “ Third Party Claim ”), the Indemnified Person shall promptly deliver to the Indemnifying Person a Claim Notice, accompanied by copies of all documents and information reasonably relevant to the Third Party Claim and in the Indemnified Person’s possession. Notwithstanding the foregoing, no delay in providing such Claim Notice within the applicable survival period shall affect a Indemnified Person’s rights hereunder, unless (and then only to the extent that) the applicable Indemnifying Persons are prejudiced thereby.

(b) Upon written notice to the Indemnified Person, within thirty (30) days after receipt of the Claim Notice, the Indemnifying Person shall have the right to direct, through

56

counsel of its own choosing but reasonably acceptable to the Indemnified Person, the defense or settlement of any Third Party Claim at its own expense; provided, however, that the Indemnifying Person shall not control the defense of such Third Party Claim (unless otherwise agreed to in writing by the Indemnified Person) and shall pay the fees and expenses of counsel retained by the Indemnified Person if (1) the claim for indemnification relates to or arises in connection with any criminal or quasi criminal proceeding, action, indictment, allegation or investigation; (2) the Indemnified Person reasonably believes an adverse determination with respect to the action, lawsuit, investigation, proceeding or other claim giving rise to such claim for indemnification would be materially detrimental to or materially injurious to the Indemnified Person’s reputation or future business prospects; (3) the claim seeks an injunction or equitable relief against the Indemnified Person; (4) the Indemnified Person has been advised by counsel that a reasonable likelihood exists of a conflict of interest between the Indemnifying Person and the Indemnified Person; (5) the Indemnifying Person failed or is failing to vigorously prosecute or defend such claim; or (6) the Indemnified Person reasonably believes that the loss relating to the Third Party Claim will exceed the maximum amount that such Indemnified Person could then be entitled to recover under the applicable provisions of Article X . If the Indemnifying Person is entitled to and elects to direct the defense of any Third Party Claim, the Indemnified Person shall not pay, or permit to be paid, any part of any claim or demand arising from such asserted liability unless the Indemnifying Person consents in writing to such payment (which consent shall not be unreasonably withheld or delayed) or unless the Indemnifying Person, subject to Section 10.7(c) , withdraws from the defense of such asserted liability, or unless a final judgment from which no appeal may be taken by or on behalf of the Indemnifying Person is entered against the Indemnified Person for such liability. The Indemnifying Person shall keep the Indemnified Person timely apprised of the status of such Third Party Claim. The Indemnified Person shall retain the right to employ its own counsel and to participate, at its own expense, in the defense or handling of any Third Party Claim, the defense of which has been assumed by the Indemnifying Person pursuant hereto. If the Indemnifying Party is entitled to and has assumed the defense of any Third Party Claim, the Indemnifying Person shall not settle such Third Party Claim without the prior written consent of the Indemnified Person (which shall not be unreasonably delayed or withheld) if, pursuant to or as a result of such settlement or cessation, (1) there is an admission of wrongdoing by the Indemnified Person or its affiliates, (2) injunctive or other equitable or non-monetary relief will be imposed upon the Indemnified Person or its affiliates, (3) there is not, as a term thereof an express and unconditional release of the Indemnified Person and its affiliates from the Third Party Claim and a complete and final resolution of all such Third Party Claims against the Indemnified Party and its affiliates, and (4) the monetary relief is not fully and actually covered by the Escrow Fund or the Indemnifying Person’s indemnification obligations under this Article X .

(c) If the Indemnifying Person does not give written notice to the Indemnified Person within twenty (20) days after receipt of the Claim Notice of a Third Party Claim that the Indemnifying Person has elected to assume the defense of such Third Party Claim or if the Indemnifying Person shall fail to defend or, if after commencing or undertaking any such defense, shall fail to prosecute or shall withdraw from such defense, the Indemnified Person shall have the right to undertake the defense or settlement thereof, at the Indemnifying Person’s expense. The Indemnifying Person shall pay the cost and expenses of the handling of the defense on a current basis, and any amounts not reimbursed within 30 days after invoice based on reasonable documentation shall accrue interest at 8% per annum and be included in

57

Indemnifiable Damages. If the Indemnified Person assumes the defense of a Third Party Claim pursuant to the terms of this Section 10.7 , the Indemnified Person shall keep the Indemnifying Person timely apprised of the status of such Third Party Claim and shall, subject to this Section 10.7 , not settle such Third Party Claim without the prior written consent of the Indemnifying Person (which shall not be unreasonably delayed, withheld or conditioned and which will be deemed given if not objected to in writing within ten (10) days of written notice of the material terms of the settlement).

(d) In connection with any defense of a Third Party Claim, each of the parties to this Agreement shall, and shall cause their respective controlled affiliates to, cooperate in the defense or prosecution thereof and to in good faith retain and furnish such records, information and testimony, and attend such conferences, discovery proceedings, hearings, trials and appeals, as may be reasonably requested by any other party in connection therewith.

10.8 Limitation . The Purchaser acknowledges and agrees that it has had the opportunity to conduct due diligence and investigation with respect to the Company Entities. The Sellers shall have no liability to the Purchaser with respect to a breach of any representation or warranty under this Agreement (other than the Fundamental Representations and Section 4.23 (Accounts Receivable)) to the extent that the members of the Conflicts Committee of the Purchaser’s Board of Directors or the Representatives of the Conflicts Committee had actual knowledge of such breach as of the Closing Date based on disclosure of such breach in the Disclosure Schedule in such a manner and in such detail as to enable such members or Representatives to make an informed assessment of the nature and scope of the disclosed breach and its financial, operational or other consequences to the Company Entities.

11.4 Entire Agreement; Parties in Interest .

This Agreement and the documents and instruments and other agreements specifically referred to herein or delivered pursuant hereto, including all the exhibits attached hereto, and the Schedules, including the Disclosure Schedule, (a) constitute the entire agreement among the parties hereto with respect to the subject matter hereof and supersede all prior agreements and understandings, both written and oral, among the parties hereto with respect to the subject matter hereof, including the Memorandum of Understanding between Purchaser and Sellers dated December 12, 2011, and (b) are not intended to confer, and shall not be construed as conferring, upon any Person other than the parties hereto any rights or remedies hereunder (except that Article X is intended to benefit Indemnified Persons).

11.5 Assignment and Succession .

Neither this Agreement nor any of the rights, interests or obligations under this Agreement may be assigned or delegated, in whole or in part, by operation of law or otherwise by any of the parties hereto without the prior written consent of the other parties hereto, and any such assignment without such prior written consent shall be null and void, except that Purchaser may assign this Agreement to one or more of its affiliates without the prior consent of Sellers; provided , however , that Purchaser shall remain liable for all of its obligations under this Agreement. Subject to the preceding sentence, this Agreement shall be binding upon, inure to the benefit of, and be enforceable by, the parties hereto and their respective successors and assigns.

11.6 Severability .

In the event that any provision of this Agreement, or the application thereof, becomes or is declared by a court of competent jurisdiction to be illegal, void or unenforceable, the remainder of this Agreement shall continue in full force and effect and shall be interpreted so as reasonably to effect the intent of the parties hereto. The parties hereto shall use all reasonable efforts to replace such void or unenforceable provision of this Agreement with a valid and enforceable provision that shall achieve, to the extent possible, the economic, business and other purposes of such void or unenforceable provision.

11.7 Remedies Cumulative .

Except as otherwise provided herein, any and all remedies herein expressly conferred upon a party hereto shall be deemed cumulative with and not exclusive of any other remedy conferred hereby, or by law or equity upon such party, and the exercise by a party hereto of any one remedy shall not preclude the exercise of any other remedy and nothing in this Agreement shall be deemed a waiver by any party of any right to specific performance or injunctive relief.

2.4 Value of Securities

The Securities to be deposited and distributed pursuant to this Agreement shall be rounded to the nearest whole number and shall be valued at the Per Share Value price per share.

2.5 Release of Securities.

The Company and the Security Holders hereby direct the Escrow Agent to retain the Securities (including any replacement securities) and not to do or cause anything to be done to release the same from escrow or to allow any transfer, hypothecation or alienation thereof, except in accordance with the terms of this Agreement.

The Securities shall be released from escrow as follows:

(a) Release for Indemnification .

(i) The Company may deliver to the Escrow Agent a claim in writing (a copy of which shall be sent contemporaneously to the Security Holders by the Company) (a “ Claim ” ) setting forth that the Company reasonably believes in good faith that there is or has been a breach of a representation, warranty or covenant contained in the Purchase Agreement or that the Company is otherwise entitled to indemnification pursuant to Article X of the Purchase Agreement and describing in reasonable detail the facts and circumstances of the claim, the basis upon which indemnification is sought pursuant to the Purchase Agreement, the amount of Indemnifiable Damages that exist with respect to such claim if then ascertainable and, if not ascertainable, the estimated amount thereof (the “ Demand Amount ”). The Company shall instruct the Escrow Agent to release, subject to the other provisions of this Section 2.5 , a number of shares from the Securities which, when multiplied by the Per Share Value, equals the Demand Amount. The Escrow Agent shall have no responsibility for determining or calculating the amounts and number of shares set forth in this Section 2.5(a)(i) and the Company and or the Security Holders shall promptly provide detailed written instructions with respect to this Section 2.5(a)(i) . Notwithstanding anything to the contrary contained in this Agreement, any Claim not received by the Escrow Agent and the Security Holders prior to 5:00 p.m. Pacific Time on the Escrow Termination Date shall be of no effect.

(ii) Unless the Escrow Agent receives from the Security Holders a written notice (a) of objection to a Claim (the “ Objection Notice ”) and/or (b) that any Security Holder has satisfied its pro rata portion of the Claim in cash (“ Cash Payment Notice ”), which notices may be combined, and in each case, a copy of which shall be sent contemporaneously to the Company by the Security Holders) prior to 5:00 p.m. Pacific Time on the 20th calendar day after receipt of the related Claim by the Escrow Agent, the Escrow Agent shall release to the Company, as soon as possible after the 20th calendar day, in satisfaction of the Demand Amount set forth in such Claim, the number of Securities which, when multiplied by the Per Share Value, equals the Demand Amount, allocated among the Security Holders as follows: 25% to the KLW Trust, 25% to the KRW Trust and 50% to Thetis, to the address or account of the Company set forth in Schedule A . In any Objection Notice, the Security Holders may state an objection to all or a portion of the Demand Amount sought in such Claim. If the Security Holders object to only a portion of such Demand Amount, such Objection Notice shall instruct the Escrow Agent to release, and the Escrow Agent shall release, to the Company in accordance with this Section 2.5(a)(ii) the number of shares from the Securities which, when multiplied by the Per Share Value, equals that portion of the Demand Amount that is not contested by the Security Holders.

(iii) In the event that the Security Holders deliver to each of the Escrow Agent and the Company an Objection Notice within the time period specified in Section 2.5(a)(ii) , the Escrow Agent shall not release the number of shares from the Securities relating to the contested portion of the Demand Amount or the unspecified Indemnifiable Damages, as the case may be, until the Escrow Agent receives a Determination (hereinafter defined). If the Security Holders deliver an Objection Notice to any Claim within the time period specified in Section 2.5(a)(ii) , the Security Holders and the Company shall attempt in good faith to resolve the dispute related to the Claim. If the Company and the Security Holders resolve such dispute, such written resolution shall be binding on the Company and the Security Holders, and a settlement agreement signed by the Company and the Security Holders or other Joint Written Direction shall be sent to the Escrow Agent, which shall, upon receipt thereof, release the applicable shares from the Securities in accordance with this Agreement. Unless and until the Escrow Agent shall receive written notice that any such dispute has been resolved by the Company and the Security Holders, the Escrow Agent may assume without inquiry that such dispute has not been resolved. If the Company and the Security Holders fail to reach agreement with respect to the contested Claim within 45 days of the delivery of the Objection Notice, either the Company or the Security Holders may

commence Proceedings with respect to such disputed items in accordance with Section 11.8 of the Purchase Agreement. For purposes of this Escrow Agreement, a “ Determination ” shall mean: (x) a written settlement signed by both the Company and the Security Holders or other Joint Written Direction, or (y) a court order or a decision of an arbitrator delivered by the presenting party. In all cases, the Determination shall indicate that all or a specified portion of the Demand Amount is to be released to the Company from the Securities, or that no amount from the Securities is to be released to the Company. Any such Demand Amount specified to be released to the Company in a Determination shall promptly be delivered by Escrow Agent to the Company to the address or account specified in Schedule A . The parties acknowledge and agree that the Escrow Agent shall be entitled absolutely to rely and act upon any such order received, even if such order is found not to be final and subject to further appeal and potential reversal.

(iv) In the event that any Security Holder delivers to each of the Escrow Agent and the Company a Cash Payment Notice within the time period specified in Section 2.5(a)(ii) , the Company and the Security Holder shall deliver to the Escrow Agent, within ten Business Days of receipt of the Cash Payment Notice by the Company a Joint Written Direction, confirming that such Security Holder has paid in cash all or a portion of its pro rata portion of the Claim not contested by the Security Holders, and such notice shall instruct the Escrow Agent to release, and the Escrow Agent shall release to the Security Holder, the number of shares from the Securities which, when multiplied by the Per Share Value, equals the portion of the Security Holder’s pro rata portion of the Demand Amount paid by the Security Holder in cash. If the Security Holder pays only a portion of such Demand Amount in cash, such Joint Written Direction shall instruct the Escrow Agent to release, and the Escrow Agent shall release, to the Company in accordance with this Section 2.5(a)(ii) the number of shares from the Securities which, when multiplied by the Per Share Value, equals that portion of the Demand Amount that has not been paid in cash by the Security Holder. The Company and the Security Holders hereby agree that the purpose of the Joint Written Direction contemplated in this Section 2.5(a)(iv) is to allow the Company the opportunity to confirm calculation of the cash payment and receipt thereof.

(v) Upon the release of any Securities from escrow in connection with a Claim, the Escrow Agent shall provide notice to each Security Holder, at the address set forth in Schedule A , of the amount of Securities of the Security Holder remaining is escrow.

(b) Release of Securities .

Within three (3) Business Days following the Escrow Termination Date, the Escrow Agent shall release any remaining Securities to the Security Holders, at each Security

Holder’s address or brokerage account as specified in Schedule A , less any amount of Securities which, when multiplied by the Per Share Value, is necessary to satisfy any Demand Amounts pending at such time upon the Escrow Termination Date. Any amounts retained by the Escrow Agent with respect to pending Demand Amounts shall be released in accordance with Section 2.5(a) . If any such pending claim is resolved through a Determination after the Escrow Termination Date for an amount less than the amount retained by the Escrow Agent in respect thereof under this Section 2.5(b) , the Escrow Agent shall within three (3) Business Days of releasing Escrow Shares to the Company in satisfaction of such claim, release to the Security Holders an aggregate number of Securities which, when multiplied by the Per Share Value, equals the difference between the amount necessary to satisfy any remaining pending claims and the amount paid to the Company in satisfaction of the settled claim. The Escrow Agent shall have no responsibility for determining or calculating the amounts and number of shares set forth in this Section 2.5(b) and the Company and/or the Security Holders shall provide detailed written instructions with respects to this Section 2.5(b) .

2.6 Dividends

If during the period in which any of the Securities are retained in escrow pursuant hereto, any dividend is received by the Escrow Agent in respect of the Securities, other than in connection with a stock split, whether effected directly or through a stock dividend, shall be forthwith paid or transferred to the respective Security Holders entitled thereto to each Security Holder’s address or brokerage account as specified on Schedule A for stock dividends, and to each Security Holder’s bank account, as specified on Schedule A , for cash dividends, and shall not be subject to the terms of this Agreement.

2.7 Voting Rights

All voting rights attached to the Securities shall at all times be exercised by the respective registered owners thereof.

The Indemnified Parties shall have the right to select and employ one counsel to represent all of the Indemnified Parties with respect to any action or claim brought or asserted against them, unless the Indemnified Parties have been advised by counsel that a reasonable likelihood exists of a conflict of interest between the Indemnified Parties, and the reasonable fees of such counsel (and such counsel’s reasonable costs and expenses) shall be paid, upon demand, by the Company and the Security Holders in the amounts set forth in Section 3.6 .

The Escrow Agent shall have the right not to act and shall not be liable for refusing to act unless it has received clear and reasonable documentation that complies with the terms of this Agreement. Such documentation must not require the exercise of any discretion or independent judgment by the Escrow Agent.

3.8 Anti-Money Laundering.

3.10 Replacement of the Escrow Agent.
