FOR VALUE RECEIVED, AMBASE CORPORATION ("AmBase" or the "Company") promises to pay, without setoff, deduction or counterclaim of any kind or nature to RICHARD A.

Interest and Maturity Date.  Interest shall accrue on the outstanding principal balance due hereunder commencing on the date hereof and continuing on all outstanding amounts until this Promissory Note (the "Note") has been paid in full.  Interest shall be calculated on the basis of a year of 360 days and paid for the actual number of days elapsed (including the first day but excluding the last day).  The entire outstanding principal balance due hereunder, all accrued interest, and any other charges or fees provided for by this Note shall be and become due and payable from AmBase to Richard A. Bianco upon the first to occur (the "Maturity Date") of the following: (a) within one (1) week after the date the Company receives funds from any source sufficient to pay all amounts due under this this Note, including  all accrued interest thereon, including without limitation, from any sale or refinancing of the Company's building at 100 Putnam Green, Greenwich, CT  06830, or (b) December 31, 2019.  As used herein the term "business day" shall mean a day of the week that is not a Saturday, Sunday or Federal banking holiday.







Prepayment.  AmBase may, at any time and from time to time without premium, penalty or advance notice (written or otherwise) from AmBase to Richard A. Bianco, prepay to Richard A. Bianco all or any portion of the outstanding balance under this Note.  Any partial prepayment shall not affect the obligation to continue to pay in full the amount outstanding hereunder until the entire unpaid principal balance hereof, along with all accrued interest, if any, and any other charges and fees, have been paid in full.







Method and Application of Payment.  AmBase shall pay all amounts payable under this Note in cash of immediately available funds: (a) by wire transfer to an account designated by Richard A.

Bianco set forth herein or at such other place as may be designated in writing by Richard A. Bianco.  All such payments shall be made without setoff, deduction or counterclaim.  All payments received by Richard A. Bianco under in connection with this Note shall be applied: first, to any charges or fees due under the Note; second, to accrued and unpaid interest; and third, to outstanding and unpaid principal due in connection with the Note.


























Collateral.  As security for repayment of all amounts due under this Note, AmBase hereby grants to Richard A. Bianco a first priority security interest in and pledge of all shares of stock of its wholly-owned subsidiary, Maiden Lane Associates, Ltd. ("MLA"). AmBase and MLA acknowledge and agree that MLA is benefiting directly from the extension of credit to AmBase provided under this Note. AmBase hereby further agrees to cause MLA to grant to Richard A. Bianco a first priority security interest in and mortgage on the Company's building at 100 Putnam Green, Greenwich, CT  06830 (the "Building"), which is wholly owned by MLA, as security for all indebtedness under this Note.
