                                    AGREEMENT
             (Junior Subordinated Convertible Increasing Rate Notes)


         This Agreement dated as of April 30, 2000 (the "Agreement"), among
Lexington Precision Corporation, a Delaware corporation (the "Company"), Michael
A. Lubin ("Lubin"), and Warren Delano ("Delano"; Lubin and Delano are sometimes
referred to herein individually as "Holder" and collectively as the "Holders").

         WHEREAS, Lubin and Delano were the holders of certain Junior
Subordinated Convertible Increasing Rate Notes due May 1, 2000, of the Company
in the aggregate original principal amounts of U.S. $505,000 and $495,000,
respectively (individually, a "Note" and collectively, the "Notes");

         WHEREAS, on January 31, 2000, the Holders agreed to defer the payment
of certain Defaulted Interest to May 1, 2000;

         WHEREAS, on February 1, 2000, Lubin & Delano converted the Notes into
shares of common stock, par value $.25 per share, of the Company;

         WHEREAS, the Company and Holders desire to, among other things, further
defer the payment of such Defaulted Interest and provide for the waiver of
certain events of default, all on and subject to the terms hereof;

         NOW, THEREFORE, in consideration of the mutual covenants contained
herein and for other good and valuable consideration, the receipt and adequacy
of which are hereby acknowledged, the parties hereto intending to be legally
bound, hereby agree as follows:

         1. WAIVER. Subject to paragraph 2 hereof, each Holder hereby waives any
Event of Default under the Notes resulting solely from the failure of the
Company to pay any principal or interest due on February 1, 2000, in respect of
the Company's 12 3/4% Senior Subordinated Notes due February 1, 2000 (the "Other
Indebtedness").

         2. RESCISSION OF WAIVERS. The waivers in paragraph 1(b) hereof shall be
automatically rescinded, without notice to the Company, in the event that the
holders of the Other Indebtedness, or the trustee in respect thereof, seeks to
accelerate the maturity of any such Other Indebtedness or to enforce or exercise
any remedies in respect thereof.

         3. MODIFICATION OF ORIGINAL NOTES.

         Notwithstanding anything to the contrary in the Notes, the Company and
each Holder hereby agree that the interest on the Notes which is due and payable
on May 1, 2000 (the "May 2000 Interest Payment"), will be deemed to be Defaulted
Interest but will be payable on the earlier of (i) August 1, 2000, or (ii) a
date that is substantially contemporaneous with the amendment of the Other
Indebtedness, as contemplated by the Company's Consent Solicitation Statement
dated December 28, 1999.
