(a)     Effective as of October 15, 2018, Section 1.6 of the Credit Agreement is replaced in its entirety by the following provision:

Subject to Lender’s receipt of an update to existing title insurance, any endorsements Lender may determine are necessary in its sole discretion, and no new exceptions to title without Lender’s written approval, the two Deeds of Trust shall be modified, at Borrower’s option, to remove all references to the Special Project Note and Special Project Loan Agreement and to reduce the maximum amount of each Deed of Trust back to $17,000,000, and any UCC Financing Statement filed in connection with the Special Project Note shall be amended to release any additional collateral granted by Borrower to secure the Special Project Note.
