As to each and every Claim released hereunder, each Loan Party hereby represents that it has received the advice of legal counsel with regard to the releases contained herein, and having been so advised, specifically waives the benefit of the provisions of Section 1542 of the Civil Code of California which provides as follows:

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

As to each and every Claim released hereunder, each Loan Party also waives the benefit of each other similar provision of applicable federal or state law (including without limitation the laws of the state of California), if any, pertaining to general releases after having been advised by its legal counsel with respect thereto.

Each Loan Party each 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 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.

(c)    Each Loan Party, for itself and on behalf of its successors, assigns, and officers, directors, employees, agents and attorneys, and any Person acting for or on behalf of, or claiming through it, hereby absolutely, unconditionally and irrevocably, covenants and agrees with and in favor of each Releasee above that it will not sue (at law, in equity, in any regulatory proceeding or otherwise) any Releasee on the basis of any Claim released, remised and discharged by such Person pursuant to the above release. If any Loan Party or any of its respective successors, assigns, or officers, directors, employees, agents or attorneys, or any Person acting for or on behalf of, or claiming through it violate the foregoing covenant, such Person, for itself and its successors, assigns and legal representatives, agrees to pay, in addition to such other damages as any Releasee may sustain as a result of such violation, all attorneys’ fees and costs incurred by such Releasee as a result of such violation.
