7.          Release. As a material part of the consideration for the Lender entering into this Modification, Borrower agrees as follows (the “Release Provision”):

7.1          Borrower hereby releases and forever discharges the Lender and the Lender’s predecessors, successors, assigns, officers, managers, directors, shareholders, employees, agents, attorneys, representatives, parent corporations, subsidiaries, and affiliates (hereinafter all of the above collectively referred to as “Lender Group”) jointly and severally from any and all claims, counterclaims, demands, damages, debts, agreements, covenants, suits, contracts, obligations, liabilities, accounts, offsets, rights, actions, and causes of action of any nature whatsoever, including, without limitation, all claims, demands, and causes of action for contribution and indemnity, whether arising at law or in equity, whether presently possessed or possessed in the future, whether known or unknown, whether liability be direct or indirect, liquidated or unliquidated, whether presently accrued or to accrue hereafter, whether absolute or contingent, foreseen or unforeseen, and whether or not heretofore asserted, which Borrower may have or claim to have against any of Lender Group.

7.2          Borrower acknowledges, warrants, and represents to Lender Group that:

7.2.1 Borrower has read and understands the effect of the Release Provision. Borrower has had the assistance of independent counsel of its own choice, or has had the opportunity to retain such independent counsel, in reviewing, discussing, and considering all the terms of the Release Provision; and if counsel was retained, counsel for Borrower has read and considered the Release Provision and advised Borrower to execute the same. Before execution of this Modification, Borrower has had adequate opportunity to make whatever investigation or inquiry it may deem necessary or desirable in connection with the subject matter of the Release Provision.

8.          Counterparts. This Modification may be executed in any number of counterparts and by the undersigned on separate counterparts. Each such counterpart shall be deemed to be an original, but all such counterparts shall together constitute one and the same agreement. This Modification shall be deemed to have been executed and delivered on the Effective Date. This Modification may be transmitted and signed by facsimile or by portable document format (PDF). The effectiveness of any such documents and signatures shall, subject to applicable law, have the same force and effect as manually-signed originals and shall be binding on all parties. The Lender may also require that any such documents and signatures be confirmed by a manually-signed original; provided that the failure to request or deliver the same shall not limit the effectiveness of any facsimile or PDF document or signature.

9.          Severability; Waivers. If any part of this Modification is not enforceable, the rest of the Modification may be enforced. The Lender retains all rights, even if it makes a loan after default. If the Lender waives a default, it may enforce a later default.
