other causes of action with respect to the Obligations or the Loan Documents exist and (y) no portion of the Obligations is subject to avoidance, disallowance, reduction or subordination pursuant to any requirement of Law, (d) acknowledges and agrees that as of February 25, 2016, (i) the Outstanding Amount of the Revolving Credit Loans was $229,000,000.00, (ii) the Outstanding Amount of the Swing Line Loans was $0, (iii) the Outstanding Amount of the L/C Obligations was $150,000.00 and (iv) the Outstanding Amount of the Term Loans was $223,750,000.00, (e) agrees that such ratification and reaffirmation is not a condition to the continued effectiveness of the Loan Documents, and (f) agrees that neither such ratification and reaffirmation, nor the Administrative Agent’s, the L/C Issuer’s nor any Lender’s solicitation of such ratification and reaffirmation, constitutes a course of dealing giving rise to any obligation or condition requiring a similar or any other ratification or reaffirmation from each party to the Credit Agreement with respect to any subsequent modifications, consent or waiver with respect to the Credit Agreement or other Loan Documents. This Amendment shall constitute a “Loan Document” for purposes of the Credit Agreement.

6.2 Release; Covenant Not to Xxx; Acknowledgement. (a) Each Loan Party hereby absolutely and unconditionally releases and forever discharges the Administrative Agent, the L/C Issuer, the Swing Line Lender, each Lender and each of their respective Related Parties (each a “Released Party”) from any and all claims, demands or causes of action of any kind, nature or description, whether arising in law or equity or upon contract or tort or under any state or federal law or otherwise, which any Loan Party has had, now has or has made claim to have against any such Person for or by reason of any act, omission, matter, cause or thing whatsoever arising from the beginning of time to and including the Effective Date arising out of or in connection with the Obligations, the Credit Agreement, this Amendment or any other Loan Document and/or the transactions contemplated hereby or thereby, whether such claims, demands and causes of action are matured or unmatured or known or unknown. It is the intention of each Loan Party in providing this release that the same shall be effective as a bar to each and every claim, demand and cause of action specified. Each Loan Party acknowledges that it may hereafter discover facts different from or in addition to those now known or believed to be true with respect to such claims, demands, or causes of action and agrees that this instrument shall be and remain effective in all respects notwithstanding any such differences or additional facts. Each Loan Party understands, acknowledges and agrees that the release set forth above may be pleaded as a full and complete defense and may be used as a basis for an injunction against any action, suit or other proceeding which may be instituted, prosecuted or attempted in breach of the provisions of such release.

(b)Each Loan Party, on behalf of itself and its successors, assigns, and other legal representatives, hereby absolutely, unconditionally and irrevocably, covenants and agrees with and in favor of each Released Party above that it will not xxx (at law, in equity, in any regulatory proceeding or otherwise) any Released Party on the basis of any claim released, remised and discharged by any Loan Party pursuant to the above release. If any Loan Party or any of their successors, assigns or other legal representatives violates the foregoing covenant, each Loan Party, for itself and its successors, assigns and legal representatives, agrees to pay, in addition to such other damages as any Released Party may sustain as a result of such violation, all reasonable attorneys’ fees and costs incurred by such Released Party as a result of such violation.

(c)Each Loan Party represents and warrants that, to its knowledge, there are no liabilities, claims, suits, debts, liens, losses, causes of action, demands, rights, damages or costs,

or expenses of any kind, character or nature whatsoever, known or unknown, fixed or contingent, which any Loan Party may have or claim to have against any Released Party arising with respect to the Obligations, the Credit Agreement, this Amendment or any other Loan Document and/or the transactions contemplated hereby or thereby.

(d)Notwithstanding anything to the contrary in this Section 6.2 and otherwise in this Amendment, the parties acknowledge and expressly agree that the release, covenant not to xxx, and other related promises set forth in this Section 6.2 do not extend to and are specifically excluded from the lawsuit filed by the Borrower, entitled Tutor Perini Corporation v. Banc of America Securities LLC, now known as Xxxxxxx Lynch, Pierce, Xxxxxx & Xxxxx Inc., successor by merger, and Bank of America, N.A., filed in the United States District Court, in the State of Massachusetts, Civil Action No. 11-10895-NMG (the “ARS Litigation”). For avoidance of doubt, the provisions in this Section 6.2 and otherwise in this Amendment do not affect the rights of the Borrower to continue to pursue the ARS Litigation in its sole discretion and to receive and retain the proceeds from any settlement or judgment that may result from the ARS Litigation.

(e)Each of the Loan Parties has been advised by counsel with respect to the release contained in this Section 6.2. Upon advice of such counsel, each of the Loan Parties hereby waives and relinquishes all of the rights and benefits each Loan Party has, or may have, with respect to the claims released under Section 1542 of the California Civil Code or any other similar statute. Section 1542 states as follows:

A GENERAL RELEASE DOES NOT EXTEND TO CLAIMS WHICH THE CREDITOR DOES NOT KNOW OR SUSPECT TO EXIST IN HIS FAVOR AT THE TIME OF EXECUTING THE RELEASE, WHICH IF KNOWN BY HIM MUST HAVE MATERIALLY AFFECTED HIS SETTLEMENT WITH THE DEBTOR.
