From and after the Closing, each Seller shall, and shall cause its Affiliates to, hold, and shall use its reasonable best efforts to cause its or their respective Representatives to hold, in confidence any and all information, whether written or oral, concerning the Company, except to the extent that any Seller can show that such information (a) is generally available to and known by the public through no fault of such Seller, any of its Affiliates or their respective Representatives; or (b) is lawfully acquired by such Seller, any of its Affiliates or their respective Representatives from and after the Closing from sources which are not prohibited from disclosing such information by a legal, contractual or fiduciary obligation. If any Seller or any of its Affiliates or Representatives are compelled to disclose any information by judicial or administrative process or by other requirements of Law, such Seller shall promptly notify Buyer in writing and shall disclose only that portion of such information which such Seller is advised by its counsel in writing is legally required to be disclosed, provided that such Seller shall use reasonable best efforts to obtain an appropriate protective order or other reasonable assurance that confidential treatment will be accorded such information.

Section 5.02Non-competition; Non-solicitation

(a)For a period of two (2) years commencing on the Closing Date, each Founder shall not, and shall not permit any of its Affiliates to, directly or indirectly, (i) engage in or assist others in engaging in the Restricted Business in the Territory; (ii) have an interest in any Person that engages directly or indirectly in the Restricted Business in the Territory in any capacity, including as a partner, shareholder, member, employee, principal, agent, trustee or consultant; or (iii) intentionally interfere in any material respect with the business relationships (whether formed prior to or after the date of this Agreement) between the Company and customers or suppliers of the Company. Notwithstanding the foregoing, any Founder may own, directly or indirectly, solely as an investment, securities of any Person traded on any national securities exchange if such Founder is not a controlling Person of, or a member of a group which controls, such Person and does not, directly or indirectly, own 5% or more of any class of securities of such Person.

(b)During the Restricted Period, each Founder shall not, and shall not permit any of its Affiliates to, directly or indirectly, hire or solicit any employee of the Company or encourage any such employee to leave such employment or hire any such employee who has left such employment, except pursuant to a general solicitation which is not directed specifically to any such employees; provided, that nothing in this Section 5.02(b) shall prevent any Founder or any of their respective Affiliates from hiring (i) any employee whose employment has been terminated by the Company or Buyer or (ii) after 180 days from the date of termination of employment, any employee whose employment has been terminated by the employee.

(c)During the Restricted Period, each Founder shall not, and shall not permit any of its Affiliates to, directly or indirectly, solicit or entice, or attempt to solicit or entice, any clients or customers of the Company or potential clients or customers of the Company for purposes of diverting their business or services from the Company in the Restricted Business.

29

(d)Each Founder acknowledges that a breach or threatened breach of its restrictions under this Section 5.02 would give rise to irreparable harm to Buyer, for which monetary damages would not be an adequate remedy, and hereby agrees that in the event of a breach or a threatened breach by any Founder of any such obligations, Buyer shall, in addition to any and all other rights and remedies that may be available to it in respect of such breach, be entitled to equitable relief, including a temporary restraining order, an injunction, specific performance and any other relief that may be available from a court of competent jurisdiction (without any requirement to post bond).

(e)Each Founder acknowledges that the restrictions contained in this Section 5.02 are reasonable and necessary to protect the legitimate interests of Buyer and constitute a material inducement to Buyer to enter into this Agreement and consummate the transactions contemplated by this Agreement. In the event that any covenant contained in this Section 5.02 should ever be adjudicated to exceed the time, geographic, product or service, or other limitations permitted by applicable Law in any jurisdiction, then any court is expressly empowered to reform such covenant, and such covenant shall be deemed reformed, in such jurisdiction to the maximum time, geographic, product or service, or other limitations permitted by applicable Law. The covenants contained in this Section 5.02 and each provision hereof are severable and distinct covenants and provisions. The invalidity or unenforceability of any such covenant or provision as written shall not invalidate or render unenforceable the remaining covenants or provisions hereof, and any such invalidity or unenforceability in any jurisdiction shall not invalidate or render unenforceable such covenant or provision in any other jurisdiction.

Section 5.03Public Announcements. Unless otherwise required by applicable Law (based upon the reasonable advice of counsel), no Seller shall make any public announcement in respect of this Agreement or the transactions contemplated hereby or otherwise communicate with any news media without the prior written consent of Buyer.

30

Section 5.06Buyer Shares.

(a)Each Seller is aware of the Buyer’s business affairs and financial condition and has acquired sufficient information about Buyer to reach an informed and knowledgeable decision to acquire the Buyer Shares issuable to it pursuant to this Agreement. Such Seller is acquiring the Buyer Shares for such Seller’s own account for investment purposes only and not with a view to, or for the resale in connection with, any “distribution” thereof for purposes of the Securities Act of 1933, as amended (the “Securities Act”).

(b)Each Seller represents that: (x) it can afford to bear the economic risk of holding Buyer Shares for an indefinite period and can afford to suffer the complete loss of such Seller’s investment in Buyer Shares; and (y) its knowledge and experience in financial and business matters is such that such Seller is capable of evaluating the risks of the investment in Buyer Shares.

(c)Each Seller fully understands that Buyer Shares are a speculative investment which involves a high degree of risk of loss of the entire investment. Each Seller is familiar with the general risks of investment in such securities. Each Seller understands that Buyer is subject to all of such risks, and the nature of the risks involved in receiving Buyer Shares.

(d)Each Seller has had the opportunity to ask questions of and receive answers from representatives of Buyer or persons acting on behalf of the Company concerning the transactions contemplated herein, and each Seller has also had the opportunity to obtain additional information necessary to verify the adequacy and the accuracy of information furnished about Buyer. All questions asked by each Seller have been answered to the satisfaction of such Seller. Each Seller has independently evaluated the risks of receiving Buyer Shares.

(e)Each Seller understands that the issuance of the Buyer Shares has not been registered under the Securities Act and the Buyer Shares are being issued in reliance upon a specific exemption therefrom, which exemption depends upon, among other things, the bona fide nature of the Seller’s investment intent as expressed herein.

(f)At the time such Seller was offered the Buyer Shares, it was, and as of the date hereof it is, and on each date on which it receives Buyer Shares, it will be an “accredited investor” as defined in Rule 501(a) under the Securities Act.

(g)Each Seller understands that the Buyer Shares will be “restricted securities” under the United States federal securities laws and may be resold without registration under the Securities Act only in very limited circumstances. In this regard, each Seller is aware of (i) the provisions of Rule 144, promulgated under the Securities Act, which in substance, permit limited public resale of “restricted securities” acquired, directly or indirectly from the issuer thereof (or from an affiliate of such issuer), in a non-public offering subject to the satisfaction of certain conditions, including a minimum “holding period” and (ii) the stop transfer restrictions to be imposed on the Buyer Shares, in substantially the form set forth below:

“THESE SHARES HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE “SECURITIES ACT”). NO SALE OR DISPOSITION MAY BE EFFECTED EXCEPT IN COMPLIANCE WITH RULE 144 UNDER SAID ACT OR AN EFFECTIVE REGISTRATION STATEMENT RELATED THERETO OR AN OPINION OF COUNSEL FOR THE HOLDER SATISFACTORY TO THE COMPANY THAT SUCH REGISTRATION IS NOT REQUIRED UNDER THE ACT OR RECEIPT OF A NO ACTION LETTER FROM THE SECURITIES AND EXCHANGE COMMISSION.”

31

(h)Buyer hereby covenants and agrees to reserve, from its authorized and unissued shares of Buyer Common Stock and Buyer Preferred Stock, not less than the aggregate number of shares of Buyer Common Stock and Buyer Preferred Stock as shall be issuable pursuant to this Agreement, including shares of Buyer Common Stock issuable upon conversion of Buyer Preferred Stock. Buyer agrees and covenants that it shall not enter into any agreement that would, directly or indirectly, limit its ability to issue the Holdback Shares or Milestone Shares hereunder.

(i)Buyer hereby covenants and agrees to include, in the definitive proxy statement for its 2021 annual meeting of stockholders, a proposal to approve the conversion of all shares of Buyer Preferred Stock issued hereunder into shares of Buyer Common Stock in accordance with the applicable rules of The Nasdaq Stock Market. Buyer shall recommend approval of such proposal to its stockholders in connection with such proxy statement, and shall use its reasonable best efforts to obtain stockholder approval at such meeting.

Article VI
Tax matters

Section 6.01Tax Covenants.

(a)Without the prior written consent of Buyer, each Seller shall not, to the extent it may affect, or relate to, the Company, and shall not permit the Company to, make, change or rescind any Tax election, amend any Tax Return or take any position on any Tax Return, take any action, omit to take any action or enter into any other transaction that would have the effect of increasing the Tax liability or reducing any Tax asset of Buyer or the Company in respect of any Post-Closing Tax Period. Each Seller agrees that Buyer is to have no liability for any Tax resulting from any action of such Seller, the Company, its Affiliates or any of their respective Representatives, and agrees to indemnify and hold harmless Buyer (and, after the Closing Date, the Company) against any such Tax or reduction of any Tax asset.

(b)All transfer, documentary, sales, use, stamp, registration, value added and other such Taxes and fees (including any penalties and interest) incurred in connection with this Agreement and the Transaction Documents (including any real property transfer Tax and any other similar Tax) shall be borne and paid by the respective party incurring such Taxes. Each party shall, at its own expense, timely file any Tax Return or other document with respect to such Taxes or fees (and any other party shall cooperate with respect thereto as necessary).

32

(c)Buyer shall prepare, or cause to be prepared, all Tax Returns required to be filed by the Company after the Closing Date with respect to a Pre-Closing Tax Period. Any such Tax Return shall be prepared in a manner consistent with past practice (unless otherwise mandatorily required by Law) and without a change of any election or any accounting method and shall be submitted by Buyer to Sellers (together with schedules, statements and, to the extent requested by Sellers, supporting documentation) at least 30 days prior to the due date (including extensions) of such Tax Return. If any Seller reasonably objects to any item on any such Tax Return, it shall, within seven days after delivery of such Tax Return, notify Buyer in writing that it so objects, specifying with particularity any such item and stating the specific factual or legal basis for any such objection. If a notice of objection shall be duly delivered, Buyer and such Seller(s) shall negotiate in good faith and use their reasonable best efforts to resolve such items, with all objections received by Sellers being considered together. If Buyer and the objecting Sellers are unable to reach such agreement within ten days after receipt by Buyer of such notice, the disputed items shall be resolved by the Independent Accountant and any determination by the Independent Accountant shall be final with respect to all parties hereto, whether or not such parties submitted objections within the applicable time period. The Independent Accountant shall resolve any disputed items within ten days of having the item referred to it pursuant to such procedures as it may require. If the Independent Accountant is unable to resolve any disputed items before the due date for such Tax Return, the Tax Return shall be filed as prepared by Buyer and then amended, if necessary, to reflect the Independent Accountant's resolution. The costs, fees and expenses of the Independent Accountant shall be borne equally by Buyer on the one hand and the objecting Sellers on the other hand. For the avoidance of doubt, a Seller that did not submit an objection shall not be responsible for any fees and expenses of the Independent Accountant. The preparation and filing of any Tax Return of the Company that does not relate to a Pre-Closing Tax Period shall be exclusively within the control of Buyer.

Section 6.02Tax Indemnification. Except to the extent treated as a liability in the calculation of Closing Working Capital, Sellers shall indemnify the Company, Buyer, and each Buyer Indemnitee, severally but not jointly (based on the proportion of the total Purchase Price actually received by each Seller), and hold them harmless from and against (a) any Loss attributable to any breach of or inaccuracy in any representation or warranty made in Section 3.20; (b) any Loss attributable to any breach or violation of, or failure to fully perform, any covenant, agreement, undertaking or obligation in Article VI; (c) all Taxes of the Company or relating to the business of the Company for all Pre-Closing Tax Periods; (d) all Taxes of any member of an affiliated, consolidated, combined or unitary group of which the Company (or any predecessor of the Company) is or was a member on or prior to the Closing Date by reason of provisions of foreign, state or local Law; and (e) any and all Taxes of any person imposed on the Company arising under the principles of transferee or successor liability or by contract, relating to an event or transaction occurring before the Closing Date. In each of the above cases, together with any out-of-pocket fees and expenses (including attorneys' and accountants' fees) incurred in connection therewith. Any amounts payable to Buyer pursuant to this Section 6.02 shall be satisfied in the manner set forth in Section 7.06 within ten Business Days after payment of such Taxes by Buyer or the Company.

33

Section 6.03Straddle Period. In the case of Taxes that are payable with respect to a taxable period that begins before and ends after the Closing Date (each such period, a "Straddle Period"), the portion of any such Taxes that are treated as Pre-Closing Taxes for purposes of this Agreement shall be:

(a)in the case of Taxes (i) based upon, or related to, income, receipts, profits, wages, capital or net worth, (ii) imposed in connection with the sale, transfer or assignment of property, or (iii) required to be withheld, deemed equal to the amount which would be payable if the taxable year ended with the Closing Date; and

(b)in the case of other Taxes, deemed to be the amount of such Taxes for the entire period multiplied by a fraction the numerator of which is the number of days in the period ending on the Closing Date and the denominator of which is the number of days in the entire period.

Section 6.04Contests. Buyer agrees to give written notice to Sellers of the receipt of any written notice by the Company, Buyer or any of Buyer's Affiliates which involves the assertion of any claim, or the commencement of any Action, in respect of which an indemnity may be sought by Buyer pursuant to this Article VI (a "Tax Claim"); provided, that failure to comply with this provision shall not affect Buyer's right to indemnification hereunder. Buyer shall control the contest or resolution of any Tax Claim; provided, however, that Buyer shall obtain the prior written consent of Sellers (which consent shall not be unreasonably withheld or delayed) before entering into any settlement of a claim or ceasing to defend such claim.

34

Section 6.05Cooperation and Exchange of Information. Sellers and Buyer shall provide each other with such cooperation and information as either of them reasonably may request of the other in filing any Tax Return pursuant to this Article VI or in connection with any audit or other proceeding in respect of Taxes of the Company. Such cooperation and information shall include providing copies of relevant Tax Returns or portions thereof, together with accompanying schedules, related work papers and documents relating to rulings or other determinations by tax authorities. Each Seller and Buyer shall retain all Tax Returns, schedules and work papers, records and other documents in its possession relating to Tax matters of the Company for any taxable period beginning before the Closing Date until the expiration of the statute of limitations of the taxable periods to which such Tax Returns and other documents relate, without regard to extensions except to the extent notified by the other party in writing of such extensions for the respective Tax periods. Prior to transferring, destroying or discarding any Tax Returns, schedules and work papers, records and other documents in its possession relating to Tax matters of the Company for any taxable period beginning before the Closing Date, each Seller or Buyer (as the case may be) shall provide the other party with reasonable written notice and offer the other party the opportunity to take custody of such materials.

Section 6.06Tax Treatment of Indemnification Payments. Any indemnification payments pursuant to this Article VI shall be treated as an adjustment to the Purchase Price by the parties for Tax purposes, unless otherwise required by Law or if deductible by Buyer or by the Company for the Post-Closing Tax Period.

Section 6.07Survival. Notwithstanding anything in this Agreement to the contrary, the provisions of Section 3.20 and this Article VI shall survive for 6 years following the Closing Date.

Section 6.08Overlap. To the extent that any obligation or responsibility pursuant to Article VII may overlap with an obligation or responsibility pursuant to this Article VI, the provisions of this Article VI shall govern.

35

All covenants and agreements of the parties contained herein (other than any covenants or agreements contained in Article VI which are subject to Article VI) shall survive the Closing for the period explicitly specified therein but in any case not longer than six (6) years following the Closing Date. Notwithstanding the foregoing, any claims asserted in good faith with reasonable specificity (to the extent known at such time) and in writing by notice from the non-breaching party to the breaching party prior to the expiration date of the applicable survival period shall not thereafter be barred by the expiration of the relevant representation or warranty and such claims shall survive until finally resolved, provided that with respect to any Direct Claim that is asserted but not finally resolved during the applicable survival period, the Indemnified Party must commence an Action against the Indemnifying Party within ninety (90) days after the Indemnifying Party was deemed to have rejected such claim pursuant to Section 7.05(c).

Section 7.02Indemnification By Sellers. Subject to the other terms and conditions of this Article VII, each Seller shall indemnify and defend, severally but not jointly (based on the proportion of the total Purchase Price actually received by each Seller), each of Buyer and its Affiliates (including the Company) and their respective Representatives (collectively, the "Buyer Indemnitees") against, and shall hold each of them harmless from and against, and shall pay and reimburse each of them for, any and all Losses incurred or sustained by, or imposed upon, the Buyer Indemnitees based upon, arising out of, with respect to or by reason of:

(a)any inaccuracy in or breach of any of the representations or warranties of Sellers contained in this Agreement (other than in respect of Section 3.20, it being understood that the sole remedy for any such inaccuracy in or breach thereof shall be pursuant to Article VI), as of the date such representation or warranty was made or as if such representation or warranty was made on and as of the Closing Date (except for representations and warranties that expressly relate to a specified date, the inaccuracy in or breach of which will be determined with reference to such specified date);

(b)any breach or non-fulfillment of any covenant, agreement or obligation to be performed by Sellers pursuant to this Agreement (other than any breach or violation of, or failure to fully perform, any covenant, agreement, undertaking or obligation in Article VI, it being understood that the sole remedy for any such breach, violation or failure shall be pursuant to Article VI); or

(c)any Transaction Expenses or Indebtedness of the Company outstanding as of the Closing to the extent not deducted from the Closing Date Buyer Shares pursuant to Section 2.05(a).

36

Section 7.03Indemnification By Buyer. Subject to the other terms and conditions of this Article VII, Buyer shall indemnify and defend Sellers and their respective Affiliates and Representatives (collectively, the "Seller Indemnitees") against, and shall hold each of them harmless from and against, and shall pay and reimburse each of them for, any and all Losses incurred or sustained by, or imposed upon, the Seller Indemnitees based upon, arising out of, with respect to or by reason of:

(a)Sellers shall not be liable to the Buyer Indemnitees for indemnification under Section 7.02(a) until the aggregate amount of all Losses in respect of indemnification under Section 7.02(a) exceeds $50,000 (the "Deductible"), in which event Sellers shall be required to pay or be liable for all such Losses exceeding the Deductible. The aggregate amount of all Losses for Sellers shall be liable pursuant to Section 7.02(a) shall not exceed $1,500,000 (the "Cap").

(b)Buyer shall not be liable to the Seller Indemnitees for indemnification under Section 7.03(a) until the aggregate amount of all Losses in respect of indemnification under Section 7.03(a) exceeds the Deductible, in which event Buyer shall be required to pay or be liable for all such Losses exceeding the Deductible. The aggregate amount of all Losses for which Buyer shall be liable pursuant to Section 7.03(a) shall not exceed the Cap.

(c)Notwithstanding the foregoing, the limitations set forth in Section 7.04(a) and Section 7.04(b) shall not apply to Losses based upon, arising out of, with respect to or by reason of any inaccuracy in or breach of any representation or warranty in Section 3.01, Section 3.02, Section 3.03, Section 3.04, Section 3.06, Section 3.13, Section 3.18, Section 3.22, and Section 4.01.

Notwithstanding the foregoing, the limitation contained in the previous sentence shall not apply to any Losses arising from fraud, criminal activity or willful misconduct on the part of a party hereto in connection with the transactions contemplated by this Agreement.

37

(d)For purposes of determining the amount of Losses pursuant to this Article VII (but not for purposes of determining whether any breach occurred), any inaccuracy in or breach of any representation or warranty shall be determined without regard to any materiality or other similar qualification contained in or otherwise applicable to such representation or warranty.

(e)Each Indemnifying Party shall use its commercially reasonable efforts to mitigate any Loss arising from or related to Article VI or this Article VIII upon becoming aware of any event or circumstance that gives rise thereto.

Section 7.05Indemnification Procedures. The party making a claim under this Article VII is referred to as the "Indemnified Party", and the party against whom such claims are asserted under this Article VII is referred to as the "Indemnifying Party".

(a)Third Party Claims. If any Indemnified Party receives notice of the assertion or commencement of any Action made or brought by any Person who is not a party to this Agreement or an Affiliate of a party to this Agreement or a Representative of the foregoing (a "Third Party Claim") against such Indemnified Party with respect to which the Indemnifying Party is obligated to provide indemnification under this Agreement, the Indemnified Party shall give the Indemnifying Party reasonably prompt written notice thereof, but in any event not later than 30 calendar days after receipt of such notice of such Third Party Claim. The failure to give such prompt written notice shall not, however, relieve the Indemnifying Party of its indemnification obligations, except and only to the extent that the Indemnifying Party forfeits rights or defenses by reason of such failure. Such notice by the Indemnified Party shall describe the Third Party Claim in detail, shall include copies of all material written evidence thereof and shall indicate the estimated amount, if reasonably practicable, of the Loss that has been or may be sustained by the Indemnified Party. The Indemnifying Party shall have the right to participate in, or by giving written notice to the Indemnified Party, to assume the defense of any Third Party Claim at the Indemnifying Party's expense and by the Indemnifying Party's own counsel, and the Indemnified Party shall cooperate in good faith in such defense; provided, that if the Indemnifying Party is a Seller, such Indemnifying Party shall not have the right to defend or direct the defense of any such Third Party Claim that (x) is asserted directly by or on behalf of a Person that is a supplier or customer of the Company, or (y) seeks an injunction or other equitable relief against the Indemnified Party. In the event that the Indemnifying Party assumes the defense of any Third Party Claim, subject to Section 7.05(b), it shall have the right to take such action as it deems necessary to avoid, dispute, defend, appeal or make counterclaims pertaining to any such Third Party Claim in the name and on behalf of the Indemnified Party. The Indemnified Party shall have the right to participate in the defense of any Third Party Claim with counsel selected by it subject to the Indemnifying Party's right to control the defense thereof. The fees and disbursements of such counsel shall be at the expense of the Indemnified Party, provided, that if in the reasonable opinion of counsel to the Indemnified Party, (A) there are legal defenses available to an Indemnified Party that are different from or additional to those available to the Indemnifying Party; or (B) there exists a conflict of interest between the Indemnifying Party and the Indemnified Party that cannot be waived, the Indemnifying Party shall be liable for the reasonable fees and expenses of counsel to the Indemnified Party in each jurisdiction for which the Indemnified Party determines counsel is required. If the Indemnifying Party elects not to compromise or defend such Third Party Claim, fails to promptly notify the Indemnified Party in writing of its election to defend as provided in this Agreement, or fails to diligently prosecute the defense of such Third Party Claim, the Indemnified Party may, subject to Section 7.05(b), pay, compromise, defend such Third Party Claim and seek indemnification for any and all Losses based upon, arising from or relating to such Third Party Claim. Sellers and Buyer shall cooperate with each other in all reasonable respects in connection with the defense of any Third Party Claim, including making available (subject to the provisions of Section 5.01) records relating to such Third Party Claim and furnishing, without expense (other than reimbursement of actual out-of-pocket expenses) to the defending party, management employees of the non-defending party as may be reasonably necessary for the preparation of the defense of such Third Party Claim.

38

(b)Settlement of Third Party Claims. Notwithstanding any other provision of this Agreement, the Indemnifying Party shall not enter into settlement of any Third Party Claim without the prior written consent of the Indemnified Party, except as provided in this Section 7.05(b). If a firm offer is made to settle a Third Party Claim without leading to liability or the creation of a financial or other obligation on the part of the Indemnified Party and provides, in customary form, for the unconditional release of each Indemnified Party from all liabilities and obligations in connection with such Third Party Claim and the Indemnifying Party desires to accept and agree to such offer, the Indemnifying Party shall give written notice to that effect to the Indemnified Party. If the Indemnified Party fails to consent to such firm offer within ten (10) days after its receipt of such notice, the Indemnified Party may continue to contest or defend such Third Party Claim and in such event, the maximum liability of the Indemnifying Party as to such Third Party Claim shall not exceed the amount of such settlement offer. If the Indemnified Party fails to consent to such firm offer and also fails to assume defense of such Third Party Claim, the Indemnifying Party may settle the Third Party Claim upon the terms set forth in such firm offer to settle such Third Party Claim. If the Indemnified Party has assumed the defense pursuant to Section 7.05(a), it shall not agree to any settlement without the written consent of the Indemnifying Party (which consent shall not be unreasonably withheld or delayed).

(c)Direct Claims. Any Action by an Indemnified Party on account of a Loss which does not result from a Third Party Claim (a "Direct Claim") shall be asserted by the Indemnified Party giving the Indemnifying Party reasonably prompt written notice thereof, but in any event not later than 30 days after the Indemnified Party becomes aware of such Direct Claim. The failure to give such prompt written notice shall not, however, relieve the Indemnifying Party of its indemnification obligations, except and only to the extent that the Indemnifying Party forfeits rights or defenses by reason of such failure. Such notice by the Indemnified Party shall describe the Direct Claim in reasonable detail, shall include copies of all material written evidence thereof and shall indicate the estimated amount, if reasonably practicable, of the Loss that has been or may be sustained by the Indemnified Party. The Indemnifying Party shall have 30 days after its receipt of such notice to respond in writing to such Direct Claim. The Indemnified Party shall allow the Indemnifying Party and its professional advisors to investigate the matter or circumstance alleged to give rise to the Direct Claim, and whether and to what extent any amount is payable in respect of the Direct Claim and the Indemnified Party shall assist the Indemnifying Party's investigation by giving such information and assistance (including access to the Company's premises and personnel and the right to examine and copy any accounts, documents or records) as the Indemnifying Party or any of its professional advisors may reasonably request. If the Indemnifying Party does not so respond within such 30 day period, the Indemnifying Party shall be deemed to have rejected such claim, in which case the Indemnified Party shall be free to pursue such remedies as may be available to the Indemnified Party on the terms and subject to the provisions of this Agreement.

39

(d)Tax Claims. Notwithstanding any other provision of this Agreement, the control of any claim, assertion, event or proceeding in respect of Taxes of the Company (including, but not limited to, any such claim in respect of a breach of the representations and warranties in Section 3.20 hereof or any breach or violation of or failure to fully perform any covenant, agreement, undertaking or obligation in Article VI) shall be governed exclusively by Article VI hereof.

Section 7.06Payments. Once a Loss is agreed to by the Indemnifying Party or finally adjudicated to be payable pursuant to this Article VII, the Loss (always subject to the applicable limitations set forth in Section 7.04) shall be satisfied (i) first, with respect to any Losses payable by Sellers, by deducting an amount of Holdback Shares in an amount equal to the Loss pursuant to Section 2.06, (ii) second, with respect to any Losses payable by Sellers, if the Loss exceeds the value of the remaining Holdback Shares, by setting off and deducting the dollar value of the excess Loss from any Milestone Payments payable to Sellers pursuant to Section 2.03 that are payable at the time such Loss is agreed to or finally adjudicated, and (iii) if any Loss remains after giving effect to clauses (i) and (ii) above, and for all Losses payable by Buyer, by wire transfer of immediately available funds within fifteen (15) Business Days of such final, non-appealable adjudication. The parties hereto agree that should an Indemnifying Party not satisfy any such obligations pursuant to clause (iii) within such fifteen (15) Business Day period, any amount payable shall accrue interest from and including the date of agreement of the Indemnifying Party or final, non-appealable adjudication to and including the date such payment has been made at a rate per annum equal to 2.5%. Such interest shall be calculated daily on the basis of a 365 day year and the actual number of days elapsed, without compounding. Notwithstanding the foregoing, Sellers shall not be required to satisfy a Loss pursuant to clause (iii) above until the Registration Date.

Section 7.07Tax Treatment of Indemnification Payments. All indemnification payments made under this Agreement shall be treated by the parties as an adjustment to the Purchase Price for Tax purposes, unless otherwise required by Law or if deductible by Buyer or the Company for the Post-Closing Tax Period.

Section 7.08Effect of Investigation. The representations, warranties and covenants of the Indemnifying Party, and the Indemnified Party's right to indemnification with respect thereto, shall not be affected or deemed waived by reason of any investigation made by or on behalf of the Indemnified Party before the Closing (including by any of its Representatives) or by reason of the fact that the Indemnified Party or any of its Representatives knew or should have known that any such representation or warranty is, was or might be inaccurate, as the case may be.

Section 7.09Exclusive Remedies. Subject to Section 5.02 and Section 8.11, the parties acknowledge and agree that their sole and exclusive remedy with respect to any and all claims (other than claims arising from fraud, criminal activity or willful misconduct on the part of a party hereto in connection with the transactions contemplated by this Agreement) for any breach of any representation, warranty, covenant, agreement or obligation set forth herein or otherwise relating to the subject matter of this Agreement, shall be pursuant to the indemnification provisions set forth in Article VI and this Article VII. In furtherance of the foregoing, each party hereby waives, to the fullest extent permitted under Law, any and all rights, claims and causes of action for any breach of any representation, warranty, covenant, agreement or obligation set forth herein or otherwise relating to the subject matter of this Agreement it may have against the other parties hereto and their Affiliates and each of their respective Representatives arising under or based upon any Law, except pursuant to the indemnification provisions set forth in Article VI and this Article VII. Nothing in this Section 7.09 shall limit any Person's right to seek and obtain any equitable relief to which any Person shall be entitled or to seek any remedy on account of any party's fraudulent, criminal or intentional misconduct.

Section 8.04Headings. The headings in this Agreement are for reference only and shall not affect the interpretation of this Agreement.

Section 8.05Severability. If any term or provision of this Agreement is invalid, illegal or unenforceable in any jurisdiction, such invalidity, illegality or unenforceability shall not affect any other term or provision of this Agreement or invalidate or render unenforceable such term or provision in any other jurisdiction. Except as provided in Section 5.02(e), upon such determination that any term or other provision is invalid, illegal or unenforceable, the parties hereto shall negotiate in good faith to modify this Agreement so as to effect the original intent of the parties as closely as possible in a mutually acceptable manner in order that the transactions contemplated hereby be consummated as originally contemplated to the greatest extent possible.

Section 8.07Successors and Assigns. This Agreement shall be binding upon and shall inure to the benefit of the parties hereto and their respective successors and permitted assigns.

No assignment shall relieve the assigning party of any of its obligations hereunder.

Section 8.08No Third-party Beneficiaries.

Section 8.09Amendment and Modification; Waiver. This Agreement may only be amended, modified or supplemented by an agreement in writing signed by Buyer and a Majority of Sellers. No amendment signed by a Majority of Sellers shall have the effect of expanding the scope of any warranty or representation given by any Seller nor of increasing the duties or liabilities of any Seller. No waiver by any party of any of the provisions hereof shall be effective unless explicitly set forth in writing and signed by the party so waiving. No waiver by any party shall operate or be construed as a waiver in respect of any failure, breach or default not expressly identified by such written waiver, whether of a similar or different character, and whether occurring before or after that waiver. No failure to exercise, or delay in exercising, any right, remedy, power or privilege arising from this Agreement shall operate or be construed as a waiver thereof; nor shall any single or partial exercise of any right, remedy, power or privilege hereunder preclude any other or further exercise thereof or the exercise of any other right, remedy, power or privilege.

SERVICE OF PROCESS, SUMMONS, NOTICE OR OTHER DOCUMENT BY MAIL TO SUCH PARTY'S ADDRESS SET FORTH HEREIN SHALL BE EFFECTIVE SERVICE OF PROCESS FOR ANY SUIT, ACTION OR OTHER PROCEEDING BROUGHT IN ANY SUCH COURT. THE PARTIES IRREVOCABLY AND UNCONDITIONALLY WAIVE ANY OBJECTION TO THE LAYING OF VENUE OF ANY SUIT, ACTION OR ANY PROCEEDING IN SUCH COURTS AND IRREVOCABLY WAIVE AND AGREE NOT TO PLEAD OR CLAIM IN ANY SUCH COURT THAT ANY SUCH SUIT, ACTION OR PROCEEDING BROUGHT IN ANY SUCH COURT HAS BEEN BROUGHT IN AN INCONVENIENT FORUM.

43

(c)EACH PARTY ACKNOWLEDGES AND AGREES THAT ANY CONTROVERSY WHICH MAY ARISE UNDER THIS AGREEMENT OR THE TRANSACTION DOCUMENTS IS LIKELY TO INVOLVE COMPLICATED AND DIFFICULT ISSUES AND, THEREFORE, EACH SUCH PARTY IRREVOCABLY AND UNCONDITIONALLY WAIVES ANY RIGHT IT MAY HAVE TO A TRIAL BY JURY IN RESPECT OF ANY LEGAL ACTION ARISING OUT OF OR RELATING TO THIS AGREEMENT, THE TRANSACTION DOCUMENTS OR THE TRANSACTIONS CONTEMPLATED HEREBY OR THEREBY. EACH PARTY TO THIS AGREEMENT CERTIFIES AND ACKNOWLEDGES THAT (A) NO REPRESENTATIVE OF ANY OTHER PARTY HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT SUCH OTHER PARTY WOULD NOT SEEK TO ENFORCE THE FOREGOING WAIVER IN THE EVENT OF A LEGAL ACTION, (B) SUCH PARTY HAS CONSIDERED THE IMPLICATIONS OF THIS WAIVER, (C) SUCH PARTY MAKES THIS WAIVER VOLUNTARILY, AND (D) SUCH PARTY HAS BEEN INDUCED TO ENTER INTO THIS AGREEMENT BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS IN THIS Section 8.10(c).
