(b) On or prior to the Closing, the Seller shall have delivered to the Buyer a written statement (the “Purchase Price Closing Settlement Statement”), provided for in Schedule C, setting forth (i) the Seller’s good faith estimate, based upon its most recently available April 2024 financial statements prior to the Closing, of the amount of the Closing Working Capital (the 3 “Preliminary Working Capital”) and the amount by which the Preliminary Working Capital exceeds or is less than the Target Working Capital (such difference, the “Preliminary Working Capital Adjustment”), (ii) the aggregate amount of Seller’s Indebtedness as of the Closing Date (which shall be the same as the amount thereof specified in the payoff letters described in Section 1.11(d)), together with a listing of the individual accounts, their payees and amounts due to each in respect thereof, (iii) the aggregate amount of Seller Transaction Expenses unpaid as of the Closing Date, together with a listing of the individual accounts, their payees and amounts due to each in respect thereof, and (iv) based on the foregoing, the amount to be paid to Seller by Xxxxx at the Closing. (c) At the Closing, the Buyer shall pay, or cause to be paid, by wire transfer of immediately available funds, an amount equal to (A) the Escrow Fund to such account provided for in the Escrow Agreement; (B) Seller’s Indebtedness, if any, in such amounts and to such accounts as set forth on the Purchase Price Closing Settlement Statement; (C) the unpaid Seller Transaction Expenses, if any, in such amounts and to such accounts as set forth on the Purchase Price Closing Settlement Statement; and (D) after payment of (A), (B) and (C) above, the balance of the Cash Payment will be paid to the Seller in the amount and to such account set forth on the Purchase Price Closing Settlement Statement. Section 1.7. Working Capital Adjustment. The Initial Purchase Price shall be adjusted after the Closing in accordance with the following procedures: (a) Within ninety (90) days following the Closing Date, Buyer shall prepare and deliver to Seller a statement (the “Initial Statement”) calculating and setting forth the actual Working Capital as of the Closing Date (the amount calculated and set forth on such Initial Statement, the “Initial Working Capital”), which statement shall be in substantially the same format as set forth in Section 1.7(a) of the Seller Disclosure Schedule and include a worksheet setting forth in reasonable detail how such amount was calculated. The Initial Statement, the Target Working Capital and the Initial Working Capital shall be prepared in accordance with GAAP, consistent with, but subject to, the methodologies and non-GAAP treatment as set forth on Section 1.7(a) of the Seller Disclosure Schedule. (b) During the thirty (30) days immediately following Seller’s receipt of the Initial Statement (the “Purchase Price Adjustment Review Period”), Seller shall be permitted to review Buyer’s working papers and any working papers of Buyer’s independent accountants relating to the preparation of the Initial Statement and the calculation of the Initial Working Capital, as well as all of the books, records and other relevant information relating to the Initial Working Capital with respect to the period up to and including the Business Day immediately prior to the Closing Date, and Buyer shall make reasonably available to Seller the individuals responsible for and knowledgeable about the information used in, and the preparation or calculation of, the Initial Statement and the Initial Working Capital; provided, however, that the independent accountants of Buyer shall not be obligated to make any working papers available to Seller unless and until Seller has signed a customary confidentiality and hold harmless agreement relating to such access to working papers in form and substance reasonably acceptable to such independent accountants. 4 (c) Seller shall notify Buyer in writing (the “Adjustment Notice”) prior to the expiration of the Purchase Price Adjustment Review Period if Seller disagrees with the Initial Statement or the Initial Working Capital. The Adjustment Notice shall set forth in reasonable detail the basis for such disagreement, the amounts involved and Seller’s determination of the amount of the Initial Working Capital. Any items not disputed in the Adjustment Notice shall be deemed to have been accepted by Seller. If no Adjustment Notice is received by Buyer on or prior to the expiration date of the Purchase Price Adjustment Review Period, then the Initial Statement and the Initial Working Capital set forth in the Initial Statement shall be deemed to have been accepted by Seller and shall become final and binding upon Seller and Buyer in accordance with the last sentence of Section 1.7(e). (d) During the thirty (30) days immediately following the delivery of an Adjustment Notice (the “Purchase Price Adjustment Consultation Period”), Seller and Buyer shall seek in good faith to resolve any disagreement that they may have with respect to the matters specified in the Adjustment Notice. (e) If, at the end of the Purchase Price Adjustment Consultation Period, Seller and Buyer have been unable to resolve all disagreements that they may have with respect to the matters specified in the Adjustment Notice, then Seller and Buyer shall submit all matters that remain in dispute with respect to the Adjustment Notice (along with a copy of the Initial Statement marked to indicate those line items that are in dispute) to a regional or national firm of independent accountants mutually acceptable to Seller and Buyer (the “Independent Accountant”). Within thirty (30) days after the submission of such matters to the Independent Accountant, or as soon as practicable thereafter, the Independent Accountant, acting as an expert and not as an arbitrator, will make a final determination, binding on Seller and Buyer, in accordance with this Section 1.7(e), of the appropriate amount of each of the line items in the Initial Statement as to which Seller and Buyer disagree as specified in the Adjustment Notice. With respect to each disputed line item, such determination, if not in accordance with the position of either Seller or Buyer, shall not be in excess of the higher, nor less than the lower, of the amounts advocated by Seller in the Adjustment Notice or Buyer in the Initial Statement with respect to such disputed line item. For the avoidance of doubt, the Independent Accountant shall not review any line items or make any determination with respect to any matter other than those matters in the Adjustment Notice that remain in dispute. The statement of the Working Capital as of the Closing and the determination of the Working Capital set forth therein that are final and binding on Seller and Buyer, as determined either through agreement of Seller and Buyer (deemed or otherwise) pursuant to Section 1.7(a) or (c) or through the determination of the Independent Accountant pursuant to this Section 1.7(e), are referred to herein as the “Final Statement” and the “Final Working Capital”, respectively. The date on which the Final Working Capital is finally determined in accordance with this Section 1.7(e) is hereinafter referred to as the “Determination Date.” (f) The cost of the Independent Accountant’s review and determination shall be shared equally by Seller and Buyer. Seller and Xxxxx shall each bear the fees of their respective counsel, auditors and other representatives incurred in connection with the determination and review of the Initial Statement. During the review by the Independent Accountant, Buyer and Seller shall each make available to the Independent Accountant such individuals and such information, books, records and work papers, as may be reasonably required by the Independent

(a) Subject to and in accordance with the provisions of this Section 5.5, Buyer may, in its sole discretion, effective upon the Closing, offer full-time employment to the Employees who are employed by Seller as of the Closing Date on compensation and benefit terms substantially similar to those afforded by Seller to such Employees immediately prior to Closing. Effective as of the Closing, Seller shall terminate, and Buyer shall hire all of the Employees who accept such offer and legally permitted to work. Each of the Employees who becomes a full-time employee of Buyer upon the Closing is hereinafter referred to as a “Transferred Employee.” (b) The employment of each Transferred Employee by Seller shall end effective as of the close of business on the Closing Date and the employment of the Transferred Employees by Buyer shall commence at or after 12:01 a.m. the next Business Day, local time.

Buyer shall cooperate and use its commercially reasonable efforts to assist Seller in giving such notices and obtaining such consents; provided, however, that Buyer shall have no obligation to give any guarantee or other consideration of any nature in connection with any such consent or to consent to any change in the terms of any agreement or arrangement which Buyer in its sole discretion may deem adverse to the interests of Buyer. (b) Buyer and Seller agree that, in the event that any consent, approval or authorization necessary or desirable to preserve for Seller any right or benefit under any lease, license, contract, commitment or other agreement or arrangement to which Seller is a party is not obtained prior to the Closing, Seller will, subsequent to the Closing, cooperate with Buyer in attempting to obtain such consent, approval or authorization as promptly thereafter as practicable.

Subject to the provisions of this Article VI, a Person that may be entitled to be indemnified under this Agreement (the “Indemnified Party”), other than in respect of a Third Party Claim, shall provide written notice to the Party or Parties liable for such indemnification (the “Indemnifying Party”) and the Buyer, specifying in reasonable detail the individual items of Losses for which indemnification is being sought, the date each such item was paid, or properly accrued or arose, and the nature of the misrepresentation, breach of warranty or claim to which such item or category is related (the “Indemnity Notice”). The Indemnity Notice shall be delivered by the Indemnified Party to the Indemnifying Party and the Buyer on or before the last day of the Escrow Period. If the Indemnifying Party, within a period of ten (10) days after the giving of the Indemnity Notice, shall not give written notice to the Indemnified Party announcing its intention to contest such assertion of the Indemnified Party, such assertion of the Indemnified Party shall be deemed accepted and the amount of the Losses shall be deemed established. If, however, the Indemnifying Party contests the assertion of the Losses, within the 10-day period, the Indemnified Party shall have the right to bring suit to resolve the contested assertion. The Indemnified Party and the Indemnifying Party may agree in writing, at any time, as to the existence and the amount of the Losses, and upon the execution of such agreement, such Losses shall be deemed established. Section 6.7. Notification of Claims. (a) An Indemnified Party shall promptly notify the Indemnifying Party in writing to Buyer or to Seller and the Members, as applicable, of any third party claim in respect of which indemnity may reasonably be sought under this Article VI, including any pending claim or demand by a third party that the Indemnified Party has determined has given or could reasonably give rise to a right of indemnification under this Agreement (including a pending claim or demand asserted by a third party against the Indemnified Party) (each, a “Third-Party Claim”), describing in reasonable detail the facts and circumstances with respect to the subject matter of such claim or demand; provided, however, that the failure to provide such notice shall not release the Indemnifying Party from any of its obligations under this Article VI except to the extent that the Indemnifying Party is materially prejudiced by such failure. 42 (b) Upon receipt of a notice of a claim for indemnity from an Indemnified Party pursuant to Section 6.7(a) in respect of a Third Party Claim, the Indemnifying Party may, by notice to the Indemnified Party delivered within ten (10) Business Days of the receipt of notice of such Third Party Claim, assume the defense and control of any Third Party Claim, with its own counsel and at its own expense, provided the Indemnifying Party shall (i) acknowledge in writing its indemnity obligations under this Article VI in full for such Third Party Claim and pay such Third Party Claim in full, agree to defend such Third Party Claim and prosecute such defense diligently and (ii) allow the Indemnified Party a reasonable opportunity to participate in the defense of such Third Party Claim with its own counsel and at its own expense. The Indemnified Party may take any actions reasonably necessary to defend such Third Party Claim prior to the time that it receives a notice from the Indemnifying Party as contemplated by the immediately preceding sentence. Each of Seller, the Members or Buyer (as the case may be), shall, and shall cause each of their Affiliates and Representatives to, cooperate fully with the Indemnifying Party in the defense of any Third Party Claim. The Indemnifying Party shall not, without the prior written consent of the Indemnified Party (which shall not be unreasonably withheld or delayed), consent to a settlement, compromise or discharge of, or the entry of any judgment arising from, any Third Party Claim, and the Indemnifying Party shall (i) pay or cause to be paid all amounts arising out of such settlement or judgment concurrently with the effectiveness of such settlement or judgment (unless otherwise provided in such judgment), (ii) not encumber any of the assets of any Indemnified Party or agree to any restriction or condition that would apply to or affect any Indemnified Party or the conduct of any Indemnified Party’s business and (iii) obtain, as a condition of any settlement, compromise, discharge, entry of judgment (if applicable), or other resolution, a complete and unconditional release of each Indemnified Party from any and all liabilities in respect of such Third Party Claim. Provided that the Indemnifying Party has assumed the defense and control of a claim or demand in accordance with this Section 6.7(b), the Indemnified Party shall not settle, compromise or consent to the entry of any judgment with respect to such claim or demand or admit to any liability with respect to such claim or demand without the prior written consent of the Indemnifying Party (which shall not be unreasonably withheld or delayed). In the event that the Indemnifying Party does not assume the defense and control of any Third Party Claim in accordance with this Section 6.7(b), the Indemnified Party shall be entitled to defend and control such claim as it deems appropriate, without prejudice to any other rights of the Indemnified Party under this Article VI. Section 6.8. Additional Indemnification Provisions. (a) Each of Seller and Buyer agree that with respect to each indemnification obligation set forth in this Article VI: (i) all Losses shall be net of any Eligible Insurance Proceeds, and (ii) in no event shall an Indemnifying Party have any liability to an Indemnified Party for any punitive, unforeseeable consequential, or special damages other than punitive or special damages payable to third parties in connection with a Third Party Claim. (b) Any amount payable by an Indemnifying Party pursuant to this Article VI shall be paid promptly and payment shall not be delayed pending any determination of Eligible Insurance Proceeds. In any case where an Indemnified Party recovers any Eligible Insurance Proceeds in respect of any Loss for which an Indemnifying Party has actually reimbursed it pursuant to this Article VI, such Indemnified Party shall promptly pay over to the Indemnifying Party the amount of such Eligible Insurance Proceeds, but not in excess of the sum of (i) any 43 amount previously paid by the Indemnifying Party to or on behalf of the Indemnified Party in respect of such claim and (ii) any amount expended by the Indemnifying Party in pursuing or defending any claim arising out of such matter. (c) If any portion of Losses to be reimbursed by the Indemnifying Party shall be covered, in whole or in part, by third party insurance coverage (including the insurance policies maintained for the benefit of Seller prior to the Closing), then any such insurance proceeds actually received by the Indemnified Party, net of costs reasonably incurred by the Indemnified Party in seeking such collection, shall be considered “Eligible Insurance Proceeds”, it being understood that such Indemnified Party shall use its reasonable efforts to make any such insurance claim. Section 6.9. Tax Treatment of Indemnity Payments. Seller, the Members and Buyer agree to treat any indemnity payment made pursuant to this Article VI as an adjustment to the Purchase Price for all income tax purposes. If, notwithstanding the treatment required by the preceding sentence, any indemnification payment under this Article VI (including this Section 6.6) is determined to be taxable to the Party receiving such payment by any Governmental Entity, the paying Party shall also indemnify the Party receiving such payment for any Taxes incurred by reason of the receipt of such payment and any Losses incurred by the party receiving such payment in connection with such Taxes (or any asserted deficiency, claim, demand, action, suit, proceeding, judgment or assessment, including the defense or settlement thereof, relating to such Taxes), which amount shall be determined by the Independent Accountant. ARTICLE VII GENERAL PROVISIONS Section 7.1. Fees and Expenses. Except as expressly provided otherwise in this Agreement, all fees, costs, and expenses, including fees and disbursements of counsel, financial advisers and accountants, incurred in connection with this Agreement, the sale of the Purchased Assets and the Ancillary Agreements shall be paid by the Party incurring such fees, costs or expenses. Section 7.2. Amendments. This Agreement may be amended, supplemented or modified only by a written instrument duly executed by or on behalf of Xxxxx and Seller. Section 7.3. Waiver. Any agreement on the part of a Party to any waiver shall be valid only if set forth in an instrument in writing signed on behalf of such Party. The failure of any Party to this Agreement to assert any of its rights under this Agreement or otherwise shall not constitute a waiver of such rights nor shall any single or partial exercise by any Party to this Agreement of any of its rights under this Agreement preclude any other or further exercise of such rights or any other rights under this Agreement. 44 Section 7.4.
