The Tax Returns relating to such Transfer Taxes shall be timely prepared by the party legally obligated to make such filing. The parties agree to cooperate with each other in connection with the preparation and filing of such Tax Returns, in obtaining all available exemptions from such Transfer Taxes and in timely providing each other with resale certificates and any other documents necessary to satisfy any such exemptions.

(e) If any provision contained in this Section 6.4 is for any reason held invalid, illegal or unenforceable in any respect, such invalidity, illegality or unenforceability will not affect any other provisions of this Section 6.4, but this Section 6.4 will be construed as if such invalid, illegal or unenforceable provision had never been contained herein. It is the intention of the parties that if any of the restrictions or covenants contained in this Section 6.4 is held to cover a geographic area or to be of a length of time that is not permitted by applicable

Law, or in any way construed to be too broad or to any extent invalid, such provision will not be construed to be null, void and of no effect, but, rather, the parties agree that a court of competent jurisdiction will construe, interpret, reform or judicially modify this Section 6.4 to provide for a covenant having the maximum enforceable geographic area, time period and other provisions (not greater than those contained herein) as will be valid and enforceable under such applicable law.

6.6 Bulk Sale Filings. The Purchaser and Seller hereby waive, in connection with the transactions contemplated by this Agreement, compliance with the “bulk sales” provision of Article 6 of the Uniform Commercial Code as it is in effect in the states where Seller owns Purchased Assets and other similar bulk transfer notice provisions (it being understood that such waiver is of technical procedure only and does not result in Purchaser being liable for any Retained Obligation of Seller or any Tax relating to the pre-Closing operation of the Business).

(a) Purchaser has offered employment in writing, effective as of the Closing Date, to all but one of the Employees with salary and benefits which Purchaser believes are, on an aggregate basis, at least as favorable to the Employees as those in effect with Seller under the Seller Benefit Plans.

policies and the Seller Benefit Plans. Purchaser shall credit the Transferred Employees with the number of hours of unused paid time off as the Transferred Employees had available to use with Seller on the Closing Date, as reflected on Schedule 4.10(g).

7.2 Seller Benefit Plans and Transferred Employees. Seller retains all assets and liabilities related to the Seller Benefit Plans.

(a) Each Transferred Employee shall be eligible to commence participation in Purchaser’s benefit plans if such Transferred Employee satisfies the eligibility requirements of the applicable plan but without regard to evidence of insurability requirements or pre-existing condition limitations. Purchaser will recognize all service of the Transferred Employees with Seller for purposes of vesting, eligibility to participate and receive benefits, benefit forms, premium subsidies or credits, and benefit calculations and accruals) under Purchaser’s benefit plans in which the Transferred Employees are eligible to participate or are enrolled by Purchaser at any time on or after the Closing Date. Notwithstanding any contrary provision contained herein, nothing shall preclude Purchaser from modifying its healthcare coverage for the Transferred Employees if necessary to address or satisfy the requirements of the Patient Protection and Affordable Care Act.

(b) Nothing contained in this Agreement shall confer upon any Transferred Employee any right to continued employment with Purchaser, nor shall anything herein interfere with the right of Purchaser to relocate or terminate the employment of any of the Transferred Employees at any time after the Closing Date.

8.1 Closing. Once the Closing occurs, all transactions shall be deemed to have taken place and to have been effective for tax and accounting purposes as of 12:01 a.m. (Eastern time) on the Closing Date.

9.1 Survival. The representations and warranties of the parties hereto contained herein shall survive the Closing for a period of [***] months after the Closing Date, except that [***] the warranties set forth in 4.12 (Taxes) shall survive the Closing for the applicable statutes of limitations, and [***] the warranties set forth in Sections 4.1 (Organization and Authorization) and 4.4(a) (Title to Assets) (collectively, the “Excluded Warranties”) shall survive the Closing indefinitely. Neither Purchaser nor Seller shall have any liability with respect to claims first asserted in connection with any representation or warranty after the applicable survival period specified therefor in this Section 9.1, it being understood that in the event notice of any claim for indemnification shall have been given within the applicable survival period, then the representations and warranties that are the subject of such indemnification claim shall survive until such time as such claim is fully resolved. The covenants and agreements of the parties contained in this Agreement shall remain in full force and effect in accordance with their terms (or, if no survival period is specified, indefinitely). The right to indemnification, reimbursement or other remedy based upon the representations, warranties, covenants and obligations set forth in this Agreement shall not be affected by any investigation conducted with respect to, or any knowledge acquired (or capable of being acquired) at any time, whether before or after the execution and delivery of this Agreement and the Closing Date, with respect to the accuracy or inaccuracy of or compliance with any such representation, warranty, covenant or obligation. Purchaser may rely upon Seller’s representations and warranties as bargained for assurances regardless of any investigation conducted by it.

9.2 Indemnification by Seller. From and after the Closing, Seller shall indemnify Purchaser, its Affiliates and their respective directors, managers, members, officers and employees (each, a “Purchaser Indemnified Party”) against, be liable to the Purchaser Indemnified Parties for, and hold each Purchaser Indemnified Party harmless from, any and all Losses incurred or suffered by each Purchaser Indemnified Party to the extent arising out of any of the following:

(a) any breach of or any inaccuracy in any representation or warranty made by Seller in this Agreement or the Related Documents (other than the Transition Services Agreement, the Retention Bonus Agreements, the Sublease and the Subcontract Agreements);

(b) any breach of or any failure by Seller to perform any covenant or obligation of Seller contained in this Agreement or the Related Documents (other than the Transition Services Agreement, the Retention Bonus Agreements, the Sublease and the Subcontract Agreements);

(d) claims of third parties based upon or arising out of the ownership or operation of the Business prior to the Closing Date (including claims by Governmental Authorities based upon audits of pre-Closing performance by Seller of any Purchased Contract);

(e) any brokers’ or finders’ fees or other commissions arising with respect to brokers, finders, financial advisors or other Persons retained or engaged by Seller or any of its Affiliates in respect of the transactions contemplated by this Agreement; and

(f) any Proceedings arising from or relating to the subject of the matters set forth in clauses (a) through (e) above.

9.3 Indemnification by Purchaser. From and after the Closing, Purchaser shall indemnify Seller, its Affiliates and their respective directors, managers, members, officers and employees (each, a “Seller Indemnified Party”) against, be liable to the Seller Indemnified Parties for, and hold each Seller Indemnified Party harmless from, any and all Losses incurred or suffered by each Seller Indemnified Party to the extent arising out of any of the following:

(a) any breach of or any inaccuracy in any representation or warranty made by Purchaser in this Agreement;

(b) any breach of or any failure by Purchaser to perform any covenant or obligation of Purchaser contained in this Agreement;

(d) claims of third parties based upon or arising out of Purchaser’s ownership or operation of the Business following the Closing Date and not covered by Section 9.2 (including claims by Governmental Authorities based upon audits of post-Closing performance by Purchaser of any Purchased Contract);

(e) any brokers’ or finders’ fees or other commissions arising with respect to brokers, finders, financial advisors or other Persons retained or engaged by Purchaser or any of its Affiliates in respect of the transactions contemplated by this Agreement; and

(f) any Proceedings arising from or relating to the subject of the matters set forth in clauses (a) through (e) above.

(a) The Purchaser Indemnified Parties shall have the right to payment by Seller under Section 9.2(a) if and only if, and only to the extent that, the Purchaser Indemnified Parties shall have incurred (i) as to all claims under Section 9.2(a), Indemnifiable Losses in excess of $[***] (the “Claims Threshold”), in which case the Purchaser Indemnified Parties shall have a right to payment only to the extent of such excess, and (ii) Indemnifiable Losses in excess of $[***] for any individual claim that is not part of a group of factually related claims. The Seller Indemnified Parties shall have the right to payment by Purchaser under Section 9.3(a) if and only if, and only to the extent that, the Seller Indemnified Parties shall have incurred, as to all claims under Section 9.3(a), Indemnifiable Losses in excess of the Claims Threshold, in which case the Seller Indemnified Parties shall have a right to payment only to the extent of such excess.

(b) Absent [***], Seller shall not be required to pay indemnifable damages under this Article IX for breaches of representations or warranties in excess of: [***]. Absent [***], Purchaser shall have no liability under or otherwise in connection with this Agreement for breaches or representations or warranties if Purchaser shall have been held liable for and satisfied claims hereunder in excess of $[***].

(c) Notwithstanding anything to the contrary in this Agreement, absent [***], and except in the case of specific performance and injunctive relief, the right of the Indemnified Parties to be indemnified pursuant to this Section 9 will be the sole and exclusive remedy with respect to any and all Losses of any kind or nature whatsoever, whether in law, equity or otherwise, known or unknown, which such parties have now or may have in the future, including without limitation, any damages or losses attributable to any inaccuracy or breach of any representation or warranty, or any failure to perform the covenants, agreements or undertakings contained in this Agreement, any disclosure schedule or certificate delivered pursuant to this Agreement.

(a) As promptly as is reasonably practicable after becoming aware of a claim for indemnification under this Agreement not involving a Third Party Claim, but in any event no later than ten (10) Business Days after first becoming aware of such claim, the Indemnified Person shall give written notice to the Indemnifying Person of such claim in accordance herewith (a “Claim Notice”); provided, however, that the failure of the Indemnified Person to give such notice shall not relieve the Indemnifying Person of its obligations under this Article IX except to the extent (if any) that the Indemnifying Person shall have been prejudiced thereby. The Claim Notice shall set forth in reasonable detail the facts and circumstances giving rise to such claim for indemnification, including the amount, if known, and any relevant supporting documentation. If the Indemnified Person is the Purchaser and is seeking to enforce such claim pursuant to the Escrow Agreement, the Indemnified Person shall also deliver a copy of the Claim Notice to the Escrow Agent.

(b) Within thirty (30) days after receipt by the Indemnifying Person of a Claim Notice, the Indemnifying Person may deliver to the Indemnified Person a written response (the “Response Notice”) in which the Indemnifying Person: (A) agrees that the full amount set forth in the Claim Notice (the “Full Amount”) is owed to the Indemnified Person (in which case the Response Notice shall be accompanied by a payment by the Indemnifying Person to the Indemnified Person of the Full Amount, by check or by wire transfer; provided, that if the Indemnified Person is the Purchaser and is seeking to enforce such claim pursuant to the Escrow Agreement, the Indemnifying Person shall also deliver a copy of the Response Notice to the Escrow Agent and instruct the Escrow Agent to disburse the Full Amount to the Indemnified Person); (B) agrees that part, but not all, of the amount set forth in the Claim Notice (the “Agreed Amount”) is owed to the Indemnified Person (in which case a copy of the Response Notice shall be delivered to the Escrow Agent along with instructions to the Escrow Agent to disburse the Agreed Amount to the Indemnified Person); or (C) indicates that no part of the amount set forth in the Claim Notice is owed to the Indemnified Person. Any part of the amount set forth in the Claim Notice that is not agreed to be released to the Indemnified Person pursuant to the Response Notice shall be the “Contested Amount”. If the Response Notice is not received by the Indemnified Person within such 30-day period, then the Indemnifying Person shall be conclusively deemed to have agreed that the Full Amount is owed to the Indemnified Person.

9.6 Notice of Third Party Claims; Assumption of Defense. The Indemnified Person shall give a Claim Notice (in the form contemplated by Section 9.5(a)) as promptly as is reasonably practicable, but in any event no later than ten (10) Business Days after receiving notice thereof, to the Indemnifying Person of the assertion of any claims, or the commencement of any Proceeding, by any Person not a party hereto in respect of which indemnity may be sought under this Agreement (a “Third Party Claim”); provided, however, that the failure of the Indemnified Person to give such notice shall not relieve the Indemnifying Person of its obligations under this Article IX except to the extent (if any) that the Indemnifying Person shall

have been prejudiced thereby. The Indemnifying Person may, at its own expense, (a) participate in the defense of any such Third Party Claim and (b) upon written notice to the Indemnified Person, at any time during the course of any such Third Party Claim, assume the defense thereof with counsel of its own choice and in the event of such assumption, shall have the exclusive right, subject to clause (a) in the proviso in Section 9.7, to settle or compromise such Third Party Claim. If the Indemnifying Person assumes such defense, the Indemnified Person shall have the right (but not the duty) to participate in the defense thereof and to employ counsel, at its own expense, separate from the counsel employed by the Indemnifying Person. Whether or not the Indemnifying Person chooses to defend or prosecute any such Third Party Claim, all of the parties hereto shall cooperate in the defense or prosecution thereof.

9.7 Settlement or Compromise. Any settlement or compromise made or caused to be made by the Indemnified Person (unless the Indemnifying Person has the exclusive right to settle or compromise under Section 9.6) or the Indemnifying Person, as the case may be, of any such Third Party Claim shall also be binding upon the Indemnifying Person or the Indemnified Person, as the case may be, in the same manner as if a final judgment or decree had been entered by a court of competent jurisdiction in the amount of such settlement or compromise; provided, however, that (a) no admission of wrongdoing, exclusion, obligation, restriction or Loss shall be imposed on the Indemnified Person as a result of such settlement or compromise without its prior written consent, which consent shall not be unreasonably withheld, conditioned or delayed, and (b) the Indemnified Person shall not compromise or settle any Third Party Claim without the prior written consent of the Indemnifying Person, which consent shall not be unreasonably withheld, conditioned or delayed.

9.8 Purchase Price Adjustments. To the extent permitted by Law, any amounts payable under Section 9.2 or Section 9.3 shall be treated by Purchaser and Seller as an adjustment to the Purchase Price.

9.9 Funding of Escrow. At the Closing, the Purchaser shall deposit the Escrow Amount with the Escrow Agent in accordance with the Escrow Agreement. The Escrow Amount will be governed by the terms set forth in the Escrow Agreement and shall be held for the purpose of indemnifying the Indemnified Persons pursuant to the indemnification provisions set forth in this Section 9.

9.10 Insurance. The amount of any Losses otherwise recoverable under this Section 9 shall be reduced to the extent necessary so that the payment by the Indemnifying Person, when added to the amount that the Indemnified Persons or their Affiliates have already actually received under insurance policies, net of (i) premium payments and costs incurred in securing the recovery, and (ii) any current or reasonable anticipated increase in insurance premiums resulting from the recovery, would not exceed the amount of the Losses incurred by the Indemnifying Person.

10.1 Expenses. Except for Transfer Taxes shared as specified in Section 6.3(c), each party hereto shall bear its own fees and expenses with respect to the transactions contemplated hereby.

10.2 Amendment. This Agreement may be amended, modified or supplemented only by an instrument in writing signed by Purchaser and Seller.

10.3 Notices. Any notice, request, instruction or other document to be given hereunder by a party hereto shall be in writing and shall be deemed to have been given, (a) when received if given in person or by courier or a courier service or (b) on the date of transmission if sent by facsimile transmission (receipt confirmed) to the facsimile number set forth below on a Business Day during or before the normal business hours of the intended recipient, and if not so sent on such a day and at such a time, on the following Business Day:

or to such other individual or address as a party hereto may designate for itself by notice given as herein provided.

10.4 Waivers. Except as otherwise provided in Article IX, the failure of a party hereto at any time or times to require performance of any provision hereof or claim damages with respect thereto shall in no manner affect its right at a later time to enforce the same. No waiver by a party of any condition or of any breach of any term, covenant, representation or warranty contained in this Agreement shall be effective unless it is in a writing signed by such party, and no waiver in any one or more instances shall be deemed to be a further or continuing waiver of any such condition or breach in other instances or a waiver of any other condition or breach of any other term, covenant, representation or warranty.

10.5 No Third Party Beneficiaries. This Agreement is solely for the benefit of the parties hereto and their respective successors and permitted assigns and, to the extent provided herein, their respective Affiliates, and nothing herein, express or implied, is intended to or shall confer upon any other Person any legal or equitable right, benefit or remedy of any nature whatsoever under or by reason of this Agreement. Without limiting the preceding sentence, no provision of Article VII shall create any third party beneficiary or other rights in any Employee or former employee (including any beneficiary or dependent thereof) of Seller or any of its Affiliates in respect of continued employment (or resumed employment) with Purchaser or any of its Affiliates, and no provision of Article VII shall create any such rights in any such Person in respect of any benefits.

10.6 Publicity. Except as otherwise required by applicable Law (including without limitation applicable SEC and NASDAQ regulations), no public announcement or other publicity

regarding the existence of this Agreement or the Related Documents or its or their contents or the transactions contemplated hereby or thereby shall be made by Purchaser, Seller or any of their respective Affiliates, officers, directors, employees, representatives or agents without the prior written consent of Purchaser and Seller, in any case, as to form, content, timing and manner of distribution or publication (which consent shall not be unreasonably withheld, conditioned or delayed). If either party determines that it is required to make such an announcement or disclosure, then it will so notify the other party and, at the reasonable request of the other party: (a) consult with the other party on the form and content of the announcement or disclosure; (b) if applicable, seek (or allow the other party to seek) confidential treatment for part or all of the announcement or disclosure; and (c) announce or disclose only those matters that are legally required to be announced or disclosed.

10.7 Further Assurances. On and after the Closing Date, each party hereto shall execute and deliver to any other party such assignments and other instruments as may be reasonably requested by such other party and are required to effectuate the transactions contemplated by this Agreement.

10.8 Severability. If any provision of this Agreement shall be held invalid, illegal or unenforceable, the validity, legality or enforceability of the other provisions hereof shall not be affected thereby, and there shall be deemed substituted for the provision at issue a valid, legal and enforceable provision as similar as possible to the provision at issue.

10.9 Entire Understanding. This Agreement and the Related Documents set forth the entire agreement and understanding of the parties hereto with respect to the transactions contemplated hereby and thereby and supersede and replace any and all prior agreements, arrangements and understandings, written or oral, between the parties relating to the subject matter hereof.

10.10 Construction of Negotiated Language. Seller and Purchaser agree that the language used in this Agreement is the language chosen by the parties to express their mutual intent, and that no rule of strict construction is to be applied against Seller or Purchaser. Each of Seller and Purchaser and their respective counsel have reviewed and negotiated the terms of this Agreement.

10.11 Applicable Law. This Agreement, and all disputes, controversies or issues arising between the parties with respect to the subject of this Agreement, shall, in each case, be governed exclusively by, and construed and enforced exclusively in accordance with, the internal laws of the State of Delaware without giving effect to the principles of conflicts of law thereof.

10.12 Jurisdiction of Disputes; Waiver of Jury Trial. Each party to this Agreement hereby: (a) agrees that any Proceeding in connection with or relating to this Agreement or any matters contemplated hereby, shall be brought exclusively in a court of competent jurisdiction

located in Wilmington, Delaware, whether a state or federal court; (b) consents and submits to personal jurisdiction in connection with any such Proceeding in any such court described in clause (a) of this Section 10.12 and to service of process upon it in accordance with the rules and statutes governing service of process; (c) waives to the full extent permitted by Law any objection that it may now or hereafter have to the venue of any such Proceeding in any such court or that any such Proceeding was brought in an inconvenient forum; (d) agrees as an alternative method of service to service of process in any such Proceeding by mailing of copies thereof to such party at its address set forth in Section 10.3; (e) agrees that any service made as provided herein shall be effective and binding service in every respect; and (f) agrees that nothing herein shall affect the rights of either party to effect service of process in any other manner permitted by Law. EACH PARTY HERETO IRREVOCABLY AND ABSOLUTELY WAIVES THE RIGHT TO A TRIAL BY JURY IN ANY DISPUTE IN CONNECTION WITH, ARISING UNDER OR RELATING TO THIS AGREEMENT, ANY RELATED AGREEMENT OR ANY MATTERS CONTEMPLATED HEREBY OR THEREBY AND AGREES TO TAKE ANY AND ALL ACTION NECESSARY OR APPROPRIATE TO EFFECT SUCH WAIVER.

10.13 Equitable Relief. Each of the parties hereto acknowledges that, in the event of any breach of this Agreement, the non-breaching party would be immediately and irreparably harmed by such breach and could not be made whole by monetary damages. It is accordingly agreed that, with respect to any such breach, each party hereto (a) shall waive, in any action for equitable relief (including specific performance, injunctive relief and any other equitable remedy), the defense of adequate remedy at law, and (b) shall be entitled to equitable relief (including the compelling of specific performance of this Agreement, injunctive relief and any other equitable remedy) with no obligation to prove actual damages or post any bond in connection therewith, in any action instituted in accordance with Section 10.12

10.14 Counterparts. This Agreement may be executed in any number of counterparts, each of which shall be deemed an original, but all of which together shall constitute one and the same instrument. Any signature page delivered by facsimile, email, PDF or other electronic means of transmission will be binding to the same extent as an original signature page.

IN WITNESS WHEREOF, the parties hereto have caused this Agreement to be executed and delivered as of the date first above written.
