{N4469832.17} 6 (g) Any certificates issued in respect of or exchange for the shares of Buyer Common Stock issuable as Buyer Stock Consideration shall include an endorsement typed or otherwise denoted conspicuously thereon of the following legend (along with any other legends that may be required under applicable Laws): “THE SHARES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (“THE ACT”), AND HAVE BEEN ACQUIRED FOR INVESTMENT AND NOT WITH A VIEW TO, OR IN CONNECTION WITH, THE SALE OR DISTRIBUTION THEREOF. NO TRANSFER MAY BE EFFECTED EXCEPT PURSUANT TO AN EFFECTIVE REGISTRATION STATEMENT UNDER THE ACT RELATED THERETO OR UNLESS THE COMPANY HAS RECEIVED AN OPINION OF COUNSEL IN A FORM SATISFACTORY TO THE COMPANY THAT SUCH SHARES MAY BE TRANSFERRED PURSUANT TO RULE 144 OR ANOTHER AVAILABLE EXEMPTION UNDER THE ACT AND THE RULES AND REGULATIONS THEREUNDER.” In the event the Buyer Common Stock issuable as Buyer Stock Consideration is represented by book-entry account on the books and records of the Buyer’s transfer agent, such book- entry shall include such a restrictive legend. (h) In no event shall the aggregate number of shares of Buyer Common Stock issued hereunder (the “Issued Shares”) exceed a number of shares equal to 19.9% of the number of shares of Buyer Common Stock outstanding immediately prior to the Closing (the “19.9% Threshold”). In the event that the number of shares of Buyer Common Stock otherwise comprising the Issued Shares would exceed the 19.9% Threshold, the number of shares of Buyer Common Stock issued as Buyer Stock Consideration will be cut back to the 19.9% Threshold and the cash component of the Purchase Price will be increased by an amount equal to the Buyer Common Stock Price with respect to each cut back share of Buyer Common Stock. Section 1.4 Closing. Subject to the terms and conditions of this Agreement, the closing of the purchase and sale of the Equity contemplated hereby (the “Closing”) shall take place by electronic exchange of duly executed documents on the next Business Day following the date on which all of the conditions to Closing set forth in Article 6 have been satisfied or waived (other than conditions which, by their nature, are to be satisfied on the Closing Date, but subject to the satisfaction or waiver thereof at the Closing), or at such other time, on such other date or by such other means as Sellers Representative and Buyer may mutually agree upon in writing (the day on which the Closing actually takes place being the “Closing Date”). The Parties agree that, should the Closing occur, the effective time and date of the consummation of the transactions contemplated herein shall be 12:01 a.m., Eastern Time, on the Closing Date. Section 1.5 Calculations. In no event later than 90 days following the Closing Date, Buyer shall, at its expense, (a) cause to be prepared, in accordance with GAAP on a basis consistent with the Seller Accounting Principles, a balance sheet of the Acquired Companies as of 11:59 p.m. on December 31, 2021, but which shall not reflect the transactions occurring at the Closing (the “Closing Balance Sheet”), together with a statement (the “Closing Date Schedule”) setting forth in reasonable detail Buyer’s calculation of the Closing Cash, Closing Company Indebtedness,

{N4469832.17} 7 Company Transaction Expenses and Closing Net Working Capital Amount, and (b) deliver to Sellers Representative the Closing Balance Sheet and the Closing Date Schedule. The Parties agree and acknowledge that the Closing Date Schedule is not intended to permit the introduction of different working capital line items, or different accounting methods, policies, practices, procedures, classifications, conventions, categorizations, definitions, principles, judgments, assumptions, techniques or estimation methods with respect to financial statements (including any of the foregoing as they relate to the nature of accounts, calculation of levels of reserves or levels of accruals), from the Seller Accounting Principles or the Sample Net Working Capital Calculation. Notwithstanding any other provision herein or elsewhere to the contrary, to the extent that the Closing Date Schedule corrects an error or noncompliance with the Seller Accounting Principles or the Sample Net Working Capital Calculation, and Sellers agree with such correction, then the Target Net Working Capital Amount shall be reduced or increased as a result of such error or noncompliance, as appropriate, to reflect such error or noncompliance. Section 1.6 Review; Disputes. (a) From and after the Effective Date, Buyer shall provide Sellers Representative and its representatives with reasonable access to the books, records, work papers and other relevant materials of the Acquired Companies, and the relevant personnel, accountants, advisors and other representatives, for the purposes of enabling Sellers Representative and its representatives to review and discuss Buyer’s calculation of the Closing Cash, Closing Company Indebtedness, Company Transaction Expenses and Closing Net Working Capital Amount. (b) If Sellers Representative disputes the calculation of any item set forth in the Closing Date Schedule, then Sellers Representative shall deliver a written notice (a “Dispute Notice”) to Buyer at any time during the 30-day period commencing upon receipt by Sellers Representative of the Closing Balance Sheet and the Closing Date Schedule, all as prepared by Buyer in accordance with the requirements of Section 1.5 (the “Review Period”). The Dispute Notice shall set forth the basis for the dispute of any such calculation in reasonable detail. (c) If Sellers Representative does not deliver a Dispute Notice to Buyer prior to the expiration of the Review Period, Buyer’s calculation of the Closing Cash, Closing Company Indebtedness, Company Transaction Expenses and Closing Net Working Capital Amount set forth in the Closing Date Schedule shall be deemed final and binding on Buyer and Sellers for all purposes of this Agreement. (d) If Sellers Representative delivers a Dispute Notice to Buyer prior to the expiration of the Review Period, then Sellers Representative and Buyer shall use commercially reasonable efforts to reach agreement on the disputed calculations set forth in such Dispute Notice. If Sellers Representative and Buyer are unable to reach agreement on the Closing Date Schedule within 30 days after the end of the Review Period, either Party shall have the right to refer such dispute after such 30th day to Ernst & Young, or if Ernst & Young is unable or unwilling to serve, to another nationally-recognized accounting or financial firm mutually agreed upon between Buyer and Sellers Representative (such firm, or any successor thereto, being referred to herein as the “Firm”). In connection with the resolution of any such dispute by the Firm: (i) each of Buyer and Sellers Representative shall have a reasonable opportunity to submit to the Firm a written statement of their views as to any disputed issues with respect to the calculation of any of the Closing Cash,

{N4469832.17} 8 Closing Company Indebtedness, Company Transaction Expenses and Closing Net Working Capital Amount, a copy of which shall also be delivered to the other Parties; (ii) the Firm shall determine the Closing Cash, Closing Company Indebtedness, Company Transaction Expenses and Closing Net Working Capital Amount in accordance with the terms of this Agreement based solely on the written submissions delivered to the Firm pursuant to sub-clause (i) of this Section 1.6(d) within 30 days of such referral and, upon reaching such determination, shall deliver a copy of its calculations to Sellers Representative and Buyer; and (iii) the determination made by the Firm of the Closing Cash, Closing Company Indebtedness, Company Transaction Expenses and Closing Net Working Capital Amount shall be final and binding on Buyer and Sellers for all purposes of this Agreement, absent manifest error or intentional misconduct. Notwithstanding anything else contained herein, in calculating the Closing Cash, Closing Company Indebtedness, Company Transaction Expenses and Closing Net Working Capital Amount, (x) the Firm shall act as an expert and not as an arbitrator, (y) the Firm shall be limited to addressing any particular disputes referred to in the Dispute Notice and (z) such calculation shall, with respect to any disputed item, be no greater than the highest amount calculated by Sellers Representative or Buyer, and no less than the lowest amount calculated by Sellers Representative or Buyer, as the case may be. All fees and expenses of the Firm shall be borne by Buyer, on the one hand, and Sellers, on the other hand, proportionately to the amount of the difference between the disputed items submitted to the Firm and the final determination of the disputed items by the Firm. For illustrative purposes only, if Buyer’s calculation of a disputed item is $80, Sellers Representative’s calculation of such disputed item is $100, and the amount as finally resolved by the Firm is $95, then Buyer shall pay 75% ((95-80) / (100-80)) of such fees and expenses and Sellers shall pay 25% ((100-95) / (100-80)) of such fees and expenses. Each Party will be responsible for 100% of its own fees and expenses relating to the dispute resolution procedures described in this Section 1.6. Section 1.7 Payment Upon Final Determination of Adjustments. (a) The “Adjustment Amount” shall initially be zero and shall be increased or decreased as follows: (i) if the Closing Cash, as finally determined in accordance with Section 1.6, is less than the Estimated Closing Cash, then the Adjustment Amount shall be decreased, dollar for dollar, by the absolute value of such shortfall; (ii) if the Closing Cash, as finally determined in accordance with Section 1.6, is greater than the Estimated Closing Cash, then the Adjustment Amount shall be increased, dollar for dollar, by the amount of such excess; (iii) if the Closing Company Indebtedness, as finally determined in accordance with Section 1.6, is less than the Estimated Closing Company Indebtedness, then the Adjustment Amount shall be increased, dollar for dollar, by the absolute value of such shortfall; (iv) if the Closing Company Indebtedness, as finally determined in accordance with Section 1.6, is greater than the Estimated Closing Company Indebtedness, then the Adjustment Amount shall be decreased, dollar for dollar, by the amount of such excess; (v) if the Company Transaction Expenses, as finally determined in accordance with Section 1.6, are less than the Estimated Company Transaction Expenses, then the Adjustment Amount shall be increased, dollar for dollar, by the absolute value of such shortfall; (vi) if the Company Transaction Expenses, as finally determined in accordance with Section 1.6, are greater than the Estimated Company Transaction Expenses, then the Adjustment Amount shall be decreased, dollar for dollar, by the amount of such excess; (vii) if the Closing Net Working Capital Amount, as finally determined in accordance with Section 1.6, is less than the Estimated Net Working Capital Amount, then the Adjustment Amount shall be decreased, dollar for dollar, by the absolute value of such shortfall; and (viii) if the Closing Net Working Capital Amount, as

{N4469832.17} 9 finally determined in accordance with Section 1.6, is greater than the Estimated Net Working Capital Amount, then the Adjustment Amount shall be increased, dollar for dollar, by the amount of such excess.

Each of Buyer, on the one hand, and Sellers, on the other hand, shall bear 50% of the fees and expenses of the Firm incurred in connection with this Section 1.9.

(b) Within 15 days after determination of the Asset Allocation pursuant to Section 1.9(a), Sellers Representative shall deliver to Buyer a statement setting forth in reasonable detail its calculation of the Gross-Up Amount including any work papers (the “Proposed Gross- Up Amount”). No later than 30 days following the delivery of the Proposed Gross-Up Amount, Buyer may deliver to Sellers Representative a statement setting forth in reasonable detail any objections thereto, the basis for such objections, and Buyer’s proposed Gross-Up Amount (“Buyer’s Gross-Up Notice”).

Xxxxxxx shall have the opportunity to earn an aggregate cash retention bonus amount of $15,000,000 in accordance with the terms and conditions of the Xxxxxxx Employment Agreement (the “Cash Retention Bonus”). Section 1.11 Earn-Out Payments. (a) Following the Closing, Buyer shall pay to Sellers, in addition to the Base Purchase Price (as it may be adjusted), in each case in accordance with their respective Consideration Percentages, additional consideration for the acquisition of the Equity based on the performance of the Acquired Companies and the occurrence of certain other events described herein during each calendar year between January 1, 2022 and December 31, 2026 (such five-year period, the “Aggregate Earn-Out Period” and each calendar year during such period, an “Annual Earn-Out Period”). With respect to each Annual Earn-Out Period, if the Aggregate IFO during such Annual Earn-Out Period exceeds the Aggregate IFO threshold for such Annual Earn-Out Period as set forth below (the “IFO Threshold”), the Sellers shall be paid an amount equal to thirty percent (30%) of the amount by which the Aggregate IFO during such Annual Earn-Out Period exceeds such IFO Threshold (the “Earn-Out Payment”); provided that in no event shall the Earn- Out Payments exceed $20,000,000 (the “Earn-Out Cap”) for the Aggregate Earn-Out Period. The IFO Thresholds are $32.7 million, $36.0 million, $39.6 million, $43.5 million and $47.9 million for the Annual Earn-Out Periods ending on December 31, 2022, December 31, 2023, December 31, 2024, December 31, 2025 and December 31, 2026, respectively. Notwithstanding anything herein to the contrary, no Seller shall be entitled to receive any Earn-Out Payment (other than Earn-Out Payments already received) if during the Aggregate Earn-Out Period (i) Xx. Xxxxxxx’x employment with Xxxxxxx LLC following the Closing is terminated for Cause (as defined in the Xxxxxxx Employment Agreement) or (ii) Xx. Xxxxxxx voluntarily resigns from his employment with Xxxxxxx LLC following the Closing in accordance with Section 8.1 of the Xxxxxxx Employment Agreement. (b) Within five (5) Business Days following the filing of Buyer’s Form 10-K, Buyer shall deliver to Sellers Representative a statement (the “Earn-Out Payment Statement”) that sets forth Buyer’s calculation of Aggregate IFO for the prior calendar year’s Annual Earn-Out Period; provided that in the event the Buyer’s Form 10-K is delayed past March 30 of the

{N4469832.17} 12 applicable year other than as a result of matters relating to the Acquired Companies, Buyer shall deliver the Earn-Out Payment Statement no later than April 15 of the applicable year. The Earn- Out Payment Statement shall be accompanied by supporting work papers and other materials prepared by Buyer in connection with the preparation thereof and, Buyer shall provide or cause to be provided to the Sellers Representative and its attorneys, accountants and other agents and representatives reasonable access (including electronic access, to the extent available), during normal business hours, to the applicable books, records, properties, personnel, advisors, accountants and other representatives of Buyer and the Acquired Companies for purposes of (i) evaluating the information in the Earn-Out Payment Statement and (ii) preparing any Earn-Out Objection. If Buyer does not deliver an Earn-Out Payment Statement by the expiration of the applicable five (5) Business Day period following the filing of Buyer’s Form 10-K, the Sellers Representative shall be entitled to prepare and deliver to Buyer such Earn-Out Payment Statement, setting forth the Sellers Representative’s calculation of Aggregate IFO for such Annual Earn-Out Period. In such event, the Sellers Representative and his attorneys, accountants and other agents and representatives shall be entitled to access all supporting work papers, books, records, properties, personnel, advisors, accountants and other representatives of Buyer and the Acquired Companies that Sellers Representative in good faith believes are relevant for purposes of preparing the Earn-Out Payment Statement. (c) During the forty five (45)-day period immediately following receipt of the Earn-Out Payment Statement, Sellers Representative or Buyer, as the case may be, may dispute the calculation of Aggregate IFO set forth on such Earn-Out Payment Statement by delivering notice of its objection (the “Earn-Out Objection”) to Buyer or Sellers Representative, as the case may be. If Sellers Representative or Buyer does not deliver the Earn-Out Objection to the other Party within such forty five (45)-day period, the calculation of Aggregate IFO for such Annual Earn-Out Period set forth in the respective Earn-Out Payment Statement shall be deemed to be final. An Earn-Out Objection delivered pursuant to this Section 1.11(c) shall specify in reasonable detail the nature and, to the extent known, dollar amount of any disagreement so asserted. During the thirty (30) days following delivery of an Earn-Out Objection, the Parties shall seek in good faith to resolve in writing any differences which they may have with respect to the matters specified in the Earn-Out Objection. At the end of such thirty (30)-day period, Sellers Representative and the Buyer shall submit any and all matters (but only such matters) which remain in dispute and which were properly included in the Earn-Out Objection to the Firm for review and resolution. Buyer and Sellers Representative shall instruct the Firm to make a final and binding determination with respect to the computation of the Aggregate IFO for such Annual Earn-Out Period in accordance with this Section 1.11(c). Buyer and Sellers Representative shall cooperate with the Firm during the term of its engagement and will use commercially reasonable efforts to cause the Firm to resolve all remaining disagreements with respect to the computation of Aggregate IFO for such Annual Earn-Out Period as soon as practicable. The Firm shall consider only those items and amounts in Buyer’s and Sellers Representative’s calculations of Aggregate IFO for such Annual Earn-Out Period that are identified as being items and amounts to which Buyer and Sellers Representative have been unable to agree. In resolving any disputed item, the Firm shall act as an expert and not as an arbitrator, and may not assign a value to any item greater than the greatest value for such item claimed by either Party or less than the smallest value for such item claimed by either Party. The Firm’s determination of Aggregate IFO for the Annual Earn-Out Period will be based solely on written materials submitted by Buyer and Sellers Representative (i.e., not on independent review) and on the definitions included herein. The Firm’s determination of

{N4469832.17} 13 Aggregate IFO for the Annual Earn-Out Period shall, absent manifest error or intentional wrongdoing by the Firm, be final and binding on the Parties (which final determination shall be requested by the Parties to be delivered not more than thirty (30) days following submission of such disputed matters), and such resolution by the Firm shall not be subject to court review or otherwise appealable. The fees and expenses of the Firm pursuant to this Section 1.11(c) shall be paid in the manner set forth in Section 1.6(d)), mutatis mutandi. (d) Within five (5) Business Days after the Annual Earn-Out Payment has been deemed final or is finally determined pursuant to Section 1.11(c) and so long as payment is due to Sellers pursuant to this Section 1.11, Sellers Representative shall deliver to the Buyer a funds flow statement, which such statement shall include the payment instructions for each of the Sellers, who shall be entitled to receive payment from Buyer in accordance with their respective Consideration Percentages. The Earn-Out Payment shall be paid in cash, by wire transfer of immediately available funds, to Sellers within five (5) Business Days following Buyer’s receipt of such funds flow statement. (e) Buyer shall have the right to set-off against any Earn-Out Payment owing to Sellers any amounts to which Buyer is entitled pursuant to (i) the purchase price adjustment provisions set forth in Section 1.7, and/or (ii) the indemnification provisions contained in Article 5 (including as specifically described in Section 5.6(c)). In furtherance of the foregoing, to the extent that Buyer is entitled, following a final, non-appealable decision of a court of competent jurisdiction, or pursuant to a settlement agreement entered into in accordance with Section 5.4, to an indemnification payment from Sellers pursuant to Article 5 (subject to terms, conditions and limitations set forth therein), the amount of such indemnification payment, as finally determined in accordance with this Agreement, may be set-off against the Earn-Out Payments due to Sellers. Any Earn-Out Payment amounts that are set-off pursuant to this Agreement shall be deemed to have been paid to Sellers for all purposes of this Agreement. (f) The right of each Seller to receive such Sellers’ Consideration Percentage of the Earn-Out Payment, if any, (i) is solely a contractual right and is not a security for purposes of any federal or state securities laws (and shall confer upon such Seller only the rights of a general unsecured creditor under applicable state law); (ii) will not be represented by any form of certificate or instrument; (iii) is not redeemable; and (iv) may not be sold, assigned, pledged, gifted, conveyed, transferred or otherwise disposed. (g) From Closing until the end of the Aggregate Earn-Out Period, Buyer shall: (i) act in good faith with respect to the operation of the Acquired Business; (ii) operate the Acquired Business in a manner consistent with the manner in which the Acquired Business was operated during the 12 month period ended on the Closing Date, (iii) not shift revenue or clients from any Acquired Company to Buyer or any Affiliate of Buyer with the intent to reduce the Acquired Companies’ Aggregate IFO;

{N4469832.17} 14 (iv) maintain the corporate, business and accounting independence of the Acquired Companies including maintenance of such accounting books and records as are necessary to facilitate the determination of the Acquired Companies’ operating income during an Annual Earn-Out Period and the corresponding Earn-Out Payment; (v) permit Xx. Xxxxxxx (for so long as he remains employed by the Buyer or any of the Buyer’s Affiliates) to manage the operations of the Acquired Companies in the same manner as he had done so in the 12 months prior to the Closing Date, including with respect to hiring, engaging or terminating employees or independent contractors, conducting marketing and sales activities, determining pricing for products and services, entering into contracts and transactions with employees and labor unions, clients, suppliers and other business partners, and purchasing equipment and other resources; (vi) not enter into any transaction in connection with the operation of the Acquired Business, except on arm’s length, market terms; (vii) not unduly or materially impose costs and expenses upon the Acquired Business; and (viii) use commercially reasonable efforts to pass on to the Acquired Business efficiency savings related to being part of a larger company (e.g., insurance cost savings). Notwithstanding anything to the contrary, the Parties acknowledge and agree that following the Closing, the Acquired Companies will be subject to certain costs associated with being acquired by a public company, e.g., corporate governance, internal controls and Xxxxxxxx-Xxxxx compliance, and the Acquired Companies’ incurrence of such costs shall not be considered a breach of this Section 1.11(g). (h) Notwithstanding anything to the contrary, an amount equal to the Earnout Cap minus the aggregate amount of Earn-Out Payments made to the Sellers as of the applicable date shall accelerate and become due and payable in accordance with Section 1.11(d) if a Change of Control of any of the Acquired Companies occurs prior to the end of the Aggregate Earn-Out Period; provided, however, that this Section 1.11(h) shall not apply if the Change of Control is effectuated by any Buyer Financing Source.

Covenantors shall return such original books and records to Buyer or its Affiliate as soon as such books and records are no longer needed in connection with the circumstances described in the immediately preceding sentence. (c) After such three year or longer period, before Buyer or any of its Affiliates shall dispose of any of such books and records relating to periods prior to the Closing, Buyer shall give at least 90 days’ prior written notice of such intention to dispose to Covenantors, and Covenantors shall be given an opportunity, at their cost and expense, to remove and retain all or any part of such books and records as it may elect.

Section 4.6 Tax Matters. (a) Seller Parties will prepare and timely file, or cause to be prepared and timely filed, all income Tax Returns of the Acquired Companies for any taxable period ending on or prior to the Closing Date (each such Tax Return of the Acquired Companies, a “Pre-Closing Tax Return”). Each Pre-Closing Tax Return required to be filed by Seller Parties shall be prepared in a manner consistent with past practice, except as required by applicable Law; provided, however that with respect to any Pre-Closing Tax Return of Xxxxxxx MD or MD Seller (as the successor to Xxxxxxx MD for income Tax purposes) that is an income Tax Return, Seller Parties shall (i) make, or cause to be made, an election described in Section 168(k)(7) of the Code (and any corresponding provision of applicable state Law) with respect to all property placed in service by Xxxxxxx MD during such taxable year, and (ii) not make, or permit to be made, any election under Section 179 of the Code (or any corresponding provision of applicable state Law) with respect to any property placed in service by Xxxxxxx MD during such taxable year. Seller Parties will deliver to Buyer at least 15 days prior to the due date for the filing of any Pre-Closing Tax Return (taking into account any applicable extensions) a copy of such Tax Return and all work papers for Buyer’s review and

{N4469832.17} 46 comment and shall consider in good faith prior to filing such Tax Return any reasonable comments submitted by Buyer in writing at least five Business Days prior the due date of such Tax Return. To the extent permitted by applicable Law, Covenantors shall include any income, gain, loss, deduction or other tax items on their Tax Returns in a manner consistent with the Schedule K-1s furnished by the Sellers to them for such periods. (b) Buyer will prepare and timely file all Tax Returns of the Acquired Companies for a Straddle Period, other than any such Tax Return for which Buyer is responsible pursuant to Section 4.6(a) of this Agreement, in accordance with applicable Law on a basis consistent with past practice, except as required by applicable Law. Buyer will deliver to Sellers Representative at least 30 days prior to the date for the filing of any such Tax Return (taking into account any applicable extensions), a statement setting forth the amount of Tax for which Sellers are responsible applying the principles of Section 4.6(c) and a copy of such Tax Return for Sellers Representative’s review and comment and consider in good faith prior to filing such Tax Return any reasonable comments submitted by Sellers Representative in writing at least five Business Days prior to the due date of such Tax Return. (c) In any case of a Tax Return for a Straddle Period, the Taxes of the Acquired Companies and Buyer shall be allocated between the Pre-Closing Tax Period and the Post-Closing Tax Period as follows: (i) in the case of any property Taxes and similar ad valorem obligations that are imposed on a periodic basis, Taxes attributable to the Pre-Closing Tax Period shall equal the Taxes for such Straddle Period multiplied by a fraction, the numerator of which is the number of days during the Straddle Period that are in the Pre-Closing Tax Period and the denominator of which is the number of days in the Straddle Period; and (ii) Taxes that (x) are based upon or related to income or receipts or (y) imposed in connection with any sale or other transfer or assignment of property (other than Transfer Taxes described in Section 4.7) attributable to the Pre-Closing Tax Period and the Post-Closing Tax Period shall be computed as if the taxable year ended as of the close of business on the Closing Date. For purposes of computing the Taxes attributable to the two portions of a taxable period pursuant to this Section 4.6(c), the amount of any item that is taken into account only once for each taxable period (e.g., the benefit of graduated tax rates, exemption amounts, etc.) shall be allocated between the two portions of the period in proportion to the number of days in each portion. (d) Buyer and Seller Parties agree to furnish or cause their Affiliates to furnish, to each other, upon request, as promptly as practicable, such information and assistance relating to the Acquired Companies and Acquired Business as is reasonably necessary for the filing of all Tax Returns and other Tax filings contemplated by this Agreement, the preparation for any audit by any taxing authority and the defense of any claim relating to Taxes of the Acquired Companies and Acquired Business. (e) The Sellers shall be entitled to any refunds (including any interest paid thereon) of Taxes of the Acquired Companies attributable to taxable periods (or portions thereof) ending on or before the Closing Date to the extent such refunds were not taken into account in the Closing Net Working Capital. The Buyer and each Buyer Affiliate shall cooperate with the Sellers Representative, at Sellers’ expense, in obtaining any refund to which the Stockholders are entitled under this Section 4.6. The Buyer shall promptly forward to or reimburse the Sellers for the amount of any such refunds (including any interest paid thereon) after receipt thereof (or claiming of such

{N4469832.17} 47 amount as a credit against other Taxes), net of any expenses reasonably incurred by Buyer in obtaining such refunds. (f) Unless required by applicable Law, Buyer shall not (and shall not cause or permit any Acquired Company to) file, amend, re-file or otherwise modify any Tax Return or Tax election, initiate any voluntary disclosure, or agree to the waiver or any extension of the statute of limitations, in each case, for the Acquired Companies with respect to any taxable period (or portion thereof) ending on or before the Closing Date, without the prior written consent of the Sellers Representative (which consent shall not be unreasonably withheld, conditioned or delayed). Section 4.7 Transfer Taxes. 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 (including any real property transfer Tax and any other similar Tax) shall be borne and paid by Buyer when due. Buyer shall, at its expense, timely file any Tax Return or other document with respect to such Taxes or fees (and Sellers Representative shall use commercially reasonable efforts, at Buyer’s expense, to cooperate in good faith with respect thereto as necessary). Section 4.8 R&W Insurance Policy. At the Closing, Buyer shall obtain and bind the buyer-side representation and warranty insurance policy to be issued by QBE Specialty Insurance Company to Buyer in connection with this Agreement (the “R&W Insurance Policy”).

Buyer shall ensure that the R&W Insurance Policy contains an irrevocable waiver by the insurer(s) of any right of subrogation against Sellers or their Affiliates (subject to a customary Fraud carveout). From and after the Closing, Buyer shall not, and shall cause its Affiliates not to, amend, modify or otherwise change, terminate or waive any provision of the R&W Policy (a) with respect to the waiver of subrogation set forth therein, or (b) in any manner that would be reasonably likely to increase or expand the ability or rights of any insurer under the R&W Insurance Policy to bring a claim, action, suit or proceeding against, or otherwise seek recourse from, any Covenantors or any of their Affiliates, in each case without the prior written consent of Sellers Representative. Section 4.9 Financial Information. Covenantors shall reasonably cooperate with Buyer and its Affiliates and their respective accountants and auditors by providing access, at Buyer’s expense, to any additional financial information as Buyer or its Affiliates may reasonably request in connection with the preparation by Buyer and its Affiliates of historical and pro forma financial statements related to the Acquired Business, as required to be included in any filing made by Buyer or any of its Affiliates with the SEC under the Securities Act of 1933, as amended, or the Securities Exchange Act of 1934, as amended, and the regulations promulgated thereunder, including Regulation S-X. Covenantors hereby consent to the inclusion or incorporation by reference of all financial statements and financial information provided to Buyer and its Affiliates pursuant to this Section 4.9 in any filing by Buyer and its Affiliates with the SEC and, upon request therefor by Buyer, agree to request that any auditor of Covenantors and the Acquired Companies that has compiled any financial statements provided to Buyer and its Affiliates pursuant to this

{N4469832.17} 48 Agreement consent to the inclusion or incorporation by reference of its compiled financial statements with respect to such financial statements in any filing by Buyer and its Affiliates with the SEC. Section 4.10 Buyer Stock Consideration. In order to induce Covenantors to enter into this Agreement, Buyer hereby agrees that it shall (i) after the Closing, use its reasonable best efforts to satisfy the current public information requirements set forth in Rule 144(c)(1) under the Securities Act and (ii) after the twelve month anniversary of the Closing, taking all actions reasonably requested by Sellers Representative to facilitate sales by Covenantors in brokers’ transactions pursuant to Rule 144(f)(1)(i) under the Securities Act, including the removal of any “restrictive” legend on certificates evidencing the Buyer Common Stock and providing an opinion of counsel at Buyer’s cost if requested by the transfer agent in connection with such removal. Covenantors shall provide Buyer, its counsel or the transfer agent with the evidence reasonably requested by them to cause the removal of any such “restrictive” legend, including any information Buyer reasonably deems necessary to determine that the legend is no longer required under the Securities Act or applicable state laws, including a certification that Covenantors are not Affiliates of Buyer (and a covenant to inform Buyer if any Covenantor should thereafter become an Affiliate and to consent to exchange any certificates or instruments representing the Buyer Common Stock comprising the Buyer Stock Consideration for ones bearing an appropriate restrictive legend) and regarding the length of time such Buyer Common Stock has been held. On the next Business Day following the Closing Date, Buyer shall deliver to the Seller Representative book entry confirmation from the registrar and transfer agent of the issuance of the Buyer Stock Consideration. Section 4.11 Indemnification of Directors and Officers. (a) From the Closing Date through the sixth anniversary thereof, Buyer shall, and shall cause the Acquired Companies to, fulfill and honor in all respects, any indemnification provisions under the Organizational Documents of the Acquired Companies or any predecessor as in effect on the date hereof, in each case with respect to their acts and omissions as directors and officers of the Acquired Companies or predecessor thereof occurring prior to the Closing Date, and in each case, subject to applicable Law. (b) If the Buyer or any of the Acquired Companies (i) shall consolidate with or merge into any other Person and shall not be the continuing or surviving corporation or entity of such consolidation or merger or (ii) shall transfer all or substantially all of its properties and assets to any Person, then, and in each such case, proper provisions shall be made so that the successor and assigns of the Buyer or such Acquired Company, as the case may be, shall assume all of the obligations of this Section 4.11. Section 4.12 Conduct of the Acquired Business Prior to Closing. From the Effective Date until the Closing (the “Interim Period”), the Acquired Companies shall, and Covenantors shall cause the Acquired Companies, as the case may be, to, use commercially reasonable efforts to operate in the Ordinary Course of Business and, subject to the requirements of this Agreement and the agreements and transactions contemplated hereby, to preserve, maintain and protect their material assets and the goodwill of the Acquired Business. Without limiting the generality of the foregoing, during the Interim Period, except as otherwise expressly contemplated by this

{N4469832.17} 49 Agreement, as set forth on Section 4.12 of the Seller Disclosure Schedule, or as consented to by Purchaser, which consent shall not be unreasonably withheld, conditioned or delayed, the Acquired Companies shall not, and Covenantors shall cause the Acquired Companies, as the case may be, not to, taken any of the actions contemplated by Section 2.8. Section 4.13 Access to Information. During the Interim Period, Covenantors will, consistent with applicable Laws, provide Buyer and its Representatives access during normal business hours and upon reasonable advance notice, to all the properties, documents, contracts, personnel files and other records of the Acquired Companies and the Acquired Business and shall furnish Buyer with copies of such documents and with such information with respect to the affairs of the Acquired Companies and the Acquired Business as Purchaser may from time to time reasonably request; provided, that such access does not (a) unreasonably interfere with the normal operations of the Acquired Companies, (b) jeopardize in any material respect the privacy, security and confidentiality of any Personal Information in accordance with applicable Laws, (c) adversely impact the attorney-client privilege between the Acquires Companies and their legal counsel.

Such notice by the Indemnified Party will describe the Third Party Claim in reasonable detail, will include the basis for the demand for indemnification under this Agreement

{N4469832.17} 53 with specificity, and will include a copy of any complaint, petition, or any other pleading received by the Indemnified Party in connection with the Third Party Claim. The Indemnifying Party will have the right to participate in the defense of such Third Party Claim at the Indemnifying Party’s expense, or at its option (subject to the limitations set forth in this Section 5.4(a)) to assume the defense thereof by appointing a recognized and reputable counsel to be the lead counsel in connection with such defense; provided, however, that the Indemnifying Party must give the Indemnified Party written notice of its election to assume control of the defense of the Third Party Claim within 15 Business Days of the Indemnifying Party’s receipt of the required notice of the Third Party Claim pursuant to this Section 5.4(a). (b) In the event the Indemnifying Party assumes the defense of the Third Party Claim, the Indemnified Party shall be entitled to participate in the defense of the Third Party Claim and to employ a recognized and reputable counsel of its choice for such purpose; provided, however, that the fees and expenses of such separate counsel shall be borne by the Indemnified Party and shall not be subject to indemnification under this Article 5. In no event shall the Indemnified Party or the Indemnifying Party settle a Third Party Claim without the prior express written consent of the other Party, such consent not to be unreasonably withheld, conditioned, or delayed (it being understood that consent shall not be deemed unreasonably withheld, conditioned or delayed if any such proposed settlement (i) would impose injunctive or other equitable relief upon the Indemnified Party, (ii) does not unconditionally release the Indemnified Party from all liabilities and obligations with respect to such claim without prejudice, (iii) would require the Indemnified Party to pay any amount, or (iv) includes any finding of, or admission or statement with respect to, a violation of Law or violation of the rights of any Indemnified Party or its Affiliates; provided, however, that such consent shall not be required if such settlement requires from the Sellers and/or the Buyer Indemnified Parties only a monetary payment for which the Indemnifying Party agrees to be solely responsible. If the Indemnifying Party is a Seller, the Indemnifying Party shall not take any action that, if taken by the Indemnified Party, would prevent or impair the Indemnified Party’s ability to recover against the R&W Insurance Policy any portion of such Third Party Claim. (c) Any claim by an Indemnified Party on account of Losses that does not result from a Third Party Claim (a “Direct Claim”) will be asserted by giving the Indemnifying Party reasonably prompt written notice thereof, but in any event not later than 30 days after the Indemnified Party becomes actually aware of such Direct Claim; provided that failure to give such notice on a timely basis shall not affect the indemnification provided hereunder except to the extent that such failure results in the forfeiture by the Indemnifying Party of rights and defenses otherwise available to the Indemnifying Party. Such notice by the Indemnified Party will describe the Direct Claim in reasonable detail, will include the basis for the demand under this Agreement with specificity, will include copies of all available material written evidence thereof, and will indicate the estimated amount, if reasonably practicable, of Losses that has been or may be sustained by the Indemnified Party. The Indemnifying Party shall have 30 days after receipt of such written notice to respond in writing to such Direct Claim. If after the expiration of such 30-day period the Indemnifying Person has not given the Indemnified Party written notice agreeing to indemnify the Indemnified Party in connection with the Direct Claim, then it is to be presumed that the Indemnifying Person has accepted the Direct Claim. Section 5.5 Miscellaneous Indemnification Provisions.

Except in the event of Fraud, the indemnification provisions of this Article 5 shall be the sole and exclusive remedy of the Indemnified Parties with respect to claims arising out of, concerning, or related to the transactions that are the subject of, this Agreement, whether sounding in contract, tort, statute, or otherwise, and whether asserted against Buyer, an Acquired Company, their respective officers, directors or employees, any of Covenantors, or any other Person.

If an Indemnified Party receives any all or any portion of such proceeds from an insurance provider or other source after receiving an indemnification payment hereunder from an Indemnifying Party (the amount of such proceeds the “Double Recovery Amount’), the Indemnified Party shall promptly return an amount equal to the Double Recovery Amount to the applicable Indemnifying Party.

Section 8.14 Waiver of Conflicts Regarding Representation; Non-Assertion of Attorney-Client Privilege. (a) Effective as of the Closing, Buyer hereby waives and agrees not to assert, and Buyer agrees to cause the Acquired Companies and each of its other subsidiaries to waive and not to assert, any conflict of interest arising out of or relating to any representation after the Closing of any Covenantor or any Affiliate, officer, employee or director of any Covenantor (any such Person, a “Designated Person”) in any matter involving this Agreement or any agreement, certificate, instrument or other document executed or delivered pursuant to this Agreement or any transaction contemplated hereby or thereby (including any litigation, arbitration, mediation or other proceeding and including any matter regarding the negotiation, execution, performance or enforceability hereof or thereof) by Xxxxxx Xxxxxx Xxxxxxxxx Xxxx and Xxxx LLP (“Counsel”) in connection with this Agreement or any agreement, certificate, instrument or other document executed or delivered pursuant to this Agreement or any transaction contemplated hereby or thereby (including the negotiation, execution or performance hereof or thereof). (b) Any privilege attaching as a result of Counsel’s representation of the Company or any Designated Person prior to the Closing (the “Pre-Closing Representation”) shall survive the Closing and shall remain in effect, and such privilege from and after the Closing shall be assigned to, belong to and be controlled by, Covenantors (on their own behalf and on behalf of the Designated Persons).

As to any privileged attorney-client communications between Counsel, on the one hand, and the Company or any Designated Person, on the other hand, prior to Closing (collectively, the “Privileged Communications”), Buyer agrees, on its own behalf and on behalf of its Affiliates (including, after the Closing, the Acquired Companies)) and their respective successors and/or assigns, that none of Buyer, any of its Affiliates (including, after the Closing, the Acquired Companies) or any of their respective successors or assigns, may use or rely on any of the Privileged Communications in any action or claim against or involving Sellers or any Designated Person. Further, the Parties understand and agree that any failure to segregate and/or restrict Buyer’s access to any Privileged Communications shall not be considered a waiver of the privilege. From and after the Closing, none of Buyer or any of its Affiliates (including, after the Closing, the Acquired Companies) shall knowingly access any Privileged Communications or the files of any Acquired Company relating to the Pre-Closing Representation with the intent to nullify the effects of the attorney-client privilege on such Privileged Communications or the files of any Acquired Company relating to the Pre-Closing Representation. Without limiting the generality of the foregoing, from and after the Closing (a) Covenantors (on their own behalf and on behalf of the Designated Persons) shall be the sole holders of the attorney-client privilege with respect to the Pre-Closing Representation, (b) to the extent that files of Counsel in respect of the Pre-Closing Representation constitute property of a client of counsel, only Covenantors (on their own behalf and on behalf of the

{N4469832.17} 64 Designated Persons) shall hold such property rights, and (c) Counsel shall have no duty whatsoever to reveal or disclose any Privileged Communications or files to Buyer, any Acquired Company or any of their respective Affiliates by reason of any attorney-client relationship between Counsel, any Acquired Company prior to the Closing, or any Designated Person (or otherwise). Section 8.15 The Sellers Representative.
