         FOR VALUE RECEIVED, LEXINGTON PRECISION CORPORATION, a corporation
organized under the laws of the State of Delaware ("LPC") and LEXINGTON RUBBER
GROUP, INC. (FKA LEXINGTON COMPONENTS, INC.), a corporation organized and
existing under the laws of the State of Delaware ("LRG") (hereinafter LPC and
LRG are referred to each as Borrower singularly and referred to jointly and
severally as the "Borrowers," which term shall mean each of the companies
individually and both of them collectively), jointly and severally promise to
pay to the order of BANK ONE, NA (fka Bank One, Akron, NA) (hereinafter referred
to as the "Bank"), the principal amount of ONE MILLION TWO HUNDRED FORTY-FOUR
THOUSAND FOUR HUNDRED FORTY-FOUR AND 52/100 DOLLARS ($1,244,444.52) pursuant to
the repayment terms and dates set forth in Section 2(B)(2)(b) of the Agreement
(as defined below), with interest on the unpaid balance of said principal amount
from the date hereof at a rate per annum equal to the Base Rate (as defined in
the Agreement) plus three-fourths of one percent (3/4%). If any installment of
principal, interest or other amounts due and payable hereunder are not paid when
due, or within any applicable grace periods set forth in the Agreement, the
Borrowers shall pay interest thereon at the rate of three percent (3.0%) per
annum in excess of the Base Rate, as defined in the Agreement hereinafter
referred to, as the same may from time to time be established but not to exceed
the maximum rate allowed by law. Bank shall have the right to assess a late
payment processing fee in the amount of the greater of FIFTY AND NO/100 DOLLARS
($50.00) or five percent (5%) of the scheduled payment in the event of a default
in payment that remains uncured for a period of at least ten (10) days.

         The Borrowers agree to pay the principal amount of this Note pursuant
to the repayment terms and dates set forth in Section 2(B)(2)(b) of the
Agreement. Monthly payments hereunder shall be applied first to interest due and
the balance to reduction of the principal amount outstanding.

         Payments of both principal of and interest on this Note shall be made
in lawful money of the United States of America, at 50 South Main Street, Akron,
Ohio 44308-1888, or at such other place as the Bank or any subsequent holder
hereof shall have designated to the Borrowers in writing. Interest payable on
this Note shall be computed on a three hundred sixty (360) day per year basis
counting the actual number of days elapsed. If any payment under this Note
becomes due and payable on a day which is not a Business Day (as defined in this
Agreement), payment thereof shall be made on the immediately succeeding Business
Day.

                                       7

         This Note is issued pursuant to and is entitled to the benefits of a
Credit Facility and Security Agreement dated as of January 31, 1997, by and
among the Borrowers and the Bank (as amended, the "Agreement"), to which
Agreement reference is hereby made for a statement of the rights and obligations
of the Bank and the duties and obligations of the Borrowers in relation thereto;
but neither this reference to said Agreement nor any provisions thereof shall
affect or impair the absolute and unconditional obligation of the Borrowers to
pay the principal of or interest on this Note when due.

         The Borrowers may prepay all or any portion of this Note at any time
and in any amount without penalty or premium, provided that all prepayments
shall be applied to installments of principal in the inverse order of their
maturities.

         If an Event of Default, as defined in said Agreement, shall occur and
shall be continuing, the principal of this Note may be declared immediately due
and payable at the option, of the Bank.

         In the event that the Borrowers fail to pay any regularly scheduled
principal or interest payment on this Note when due (other than as a result of
acceleration thereof based on a default or event of default other than the
failure to make any such regularly scheduled payments of principal or interest
on the Note when due) which failure is not cured within the ten (10) day cure
period provided in Section 6A of the Agreement (a "Payment Default"), or if an
Event of Default occurs and is continuing, which arises from fraudulent act(s)
or practice(s) of either Borrower which Event of Default is not cured within
three (3) Business Days after the Borrowers' receipt of written notice thereof
from the Bank (a "Fraud Default"), the Borrowers hereby authorize any
attorney-at-law to appear in any court of record in the State of Ohio, or in any
other state or territory of the United States, at any time or times after the
above sum becomes due, and waive the issuance and service of process and confess
judgment against it, in favor of any holder of this Note, for the amount then
appearing due, together with the costs of suit, and thereupon to release all
errors and waive all rights of appeal and stay of execution. The foregoing
warrant of attorney shall survive any judgment, it being understood that should
any judgment be vacated for any reason, the foregoing warrant of attorney
nevertheless may thereafter be used for obtaining an additional judgment or
judgments. To the extent that the provisions of the cognovit warning set forth
above the Borrowers signature specifically contradict the provisions of this
paragraph regarding the requirement of a Payment Default or a Fraud Default to
take a cognovit judgment, the provisions of this paragraph control.

         No delay on the part of any holder hereof in exercising any power or
rights hereunder shall operate as a waiver of any power or rights. Any demand or
notice hereunder to the Borrowers shall be deemed duly given or made when sent,
if given by telecopier, when delivered, if given by personal delivery or
overnight commercial carrier, or the fifth calendar day after deposit in the
United States mail, certified mail, return receipt requested, addressed to the
address (or telecopier number) set forth in Rider A of the Agreement or such
other address or telecopier number as may be hereafter designated in writing by
the Borrowers to the Bank.

organized under the laws of the State of Delaware ("LPC") and LEXINGTON RUBBER
GROUP, INC. (FKA LEXINGTON COMPONENTS, INC.), a corporation organized and
existing under the laws of the State of Delaware ("LRG") (hereinafter LPC and
LRG are referred to each as Borrower singularly and referred to jointly and
severally as the "Borrowers," which term shall mean each of the companies
individually and both of them collectively), jointly and severally promise to
pay to the order of BANK ONE, NA (fka Bank One, Akron, NA) (hereinafter referred
to as the "Bank"), the principal amount of EIGHT HUNDRED NINETY-EIGHT THOUSAND
TWO HUNDRED AND 24/100 DOLLARS ($898,200.24), pursuant to the repayment terms
and dates set forth in Section 2(C)(2)(b) of the Agreement (as defined below),
or sooner as hereinafter provided, with interest on the unpaid balance of said
principal amount from the date hereof at a rate per annum equal to the Base Rate
(as defined in the Agreement) plus three-fourths of one percent (3/4%). If any
installment of principal, interest or other amounts due and payable hereunder
are not paid when due, or within any applicable grace periods set forth in the
Agreement, the Borrowers shall pay interest thereon at the rate of three percent
(3.0%) per annum in excess of the Base Rate (as defined in the Agreement) as the
same may from time to time be established but not to exceed the maximum rate
allowed by law. Bank shall have the right to assess a late payment processing
fee in the amount of the greater of FIFTY AND NO/100 DOLLARS ($50.00) or five
percent (5%) of the scheduled payment in the event of a default in payment that
remains uncured for a period of at least ten (10) days.

         The Borrowers agree to pay the principal amount of this Note pursuant
to the repayment terms and dates set forth in Section 2(B)(2)(b) of the
Agreement. Monthly payments hereunder shall be applied first to interest due and
the balance to reduction of the principal amount outstanding.

         Payments of both principal of and interest on this Note shall be made
in lawful money of the United States of America, at 50 South Main Street, Akron,
Ohio 44308-1888, or at such other place as the Bank or any subsequent holder
hereof shall have designated to the Borrowers in writing. Interest payable on
this Note shall be computed on a three hundred sixty (360) day per year basis
counting the actual number of days elapsed. If any payment under this Note
becomes due and payable on a day which is not a Business Day (as defined in this
Agreement), payment thereof shall be made on the immediately succeeding Business
Day.

         This Note is issued pursuant to and is entitled to the benefits of a
Credit Facility and Security Agreement dated January 31, 1997, by and among the
Borrowers and the Bank (as amended, the "Agreement"), to which Agreement
reference is hereby made for a statement of the rights and obligations of the
Bank and the duties and obligations of the Borrowers in relation thereto; but
neither this reference to said Agreement nor any provisions thereof shall affect
or impair the absolute and unconditional obligation of the Borrowers to pay the
principal of or interest on this Note when due.

         The Borrowers may prepay all or any portion of this Note at any time
and in any amount without penalty or premium, provided that all prepayments
shall be applied to installments of principal in the inverse order of their
maturities.

         If an Event of Default (as defined in the Agreement), shall occur and
shall be continuing, the principal of this Note may be declared immediately due
and payable at the option of the Bank.

         In the event that the Borrowers fail to pay any regularly scheduled
principal or interest payment on this Note when due (other than as a result of
acceleration thereof based on a default or event of default other than the
failure to make any such regularly scheduled payments of principal or interest
on the Note when due) which failure is not cured within the ten (10) day cure
period provided in Section 6A of the Agreement (a "Payment Default"), or if an
Event of Default occurs and is continuing, which arises from fraudulent act(s)
or practice(s) of either Borrower which Event of Default is not cured within
three (3) Business Days after the Borrowers' receipt of written notice thereof
from the Bank (a "Fraud Default"), the Borrowers hereby authorize any
attorney-at-law to appear in any court of record in the State of Ohio, or in any
other state or territory of the United States, at any time or times after the
above sum becomes due, and waive the issuance and service of process and confess
judgment against it, in favor of any holder of this Note, for the amount then
appearing due, together with the costs of suit, and thereupon to release all
errors and waive all rights of appeal and stay of execution. The foregoing
warrant of attorney shall survive any judgment, it being understood that should
any judgment be vacated for any reason, the foregoing warrant of attorney
nevertheless may thereafter be used for obtaining an additional judgment or
judgments. To the extent that the provisions of the cognovit warning set forth
above the Borrowers' signature specifically contradict the provisions of this
paragraph regarding the requirement of a Payment Default or a Fraud Default to
take a cognovit judgment, the provisions of this paragraph control.

         No delay on the part of any holder hereof in exercising any power or
rights hereunder shall operate as a waiver of any power or rights. Any demand or
notice hereunder to the Company shall be deemed duly given or made when sent, if
given by telecopier, when delivered, if given by personal delivery or overnight
commercial carrier, or the fifth calendar day after deposit in the United States
mail, certified mail, return receipt requested, addressed to the address (or
telecopier number) set forth in Rider A of the Agreement or such other address
or telecopier number as may be hereafter designated in writing by the Borrowers
to the Bank.

                                    AGREEMENT

         This Agreement dated as of April 30, 2002 (the "Agreement"), between
Lexington Precision Corporation, a Delaware corporation (the "LPC"), and The CIT
Group/Equipment Financing, Inc. ("Lender").

         WHEREAS, Lender and LPC have entered into a certain Loan and Security
Agreement dated as of March 19, 1997, including Rider A thereto, as amended, and
certain supplements, documents, instruments, and agreements in connection
therewith and LPC has executed certain promissory notes in connection therewith
(all of the foregoing, as amended, modified, and supplemented, being referred to
collectively as the "Loan Documents").

         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, the Lender hereby waives,
until July 31, 2002, any Default or Event of Default under any of the Loan
Documents, resulting solely from the failure of LPC to pay any principal or
interest due on February 1, 2000, May 1, 2000, August 1, 2000, November 1, 2000,
February 1, 2001, May 1, 2001, August 1, 2001, November 1, 2001, February 1,
2002, or May 1, 2002, in respect of (a) LPC's 14% Junior Subordinated Notes due
February 1, 2002, (b) LPC's Junior Subordinated Convertible Increasing Rate
Notes due May 1, 2000, and/or (c) LPC's 12 3/4% Senior Subordinated Notes due
February 1, 2000 (the indebtedness referred to in clauses (a), (b) and (c) is
referred to herein as the "Other Indebtedness").

         2. RESCISSION OF WAIVERS. The foregoing waivers shall be automatically
rescinded, without notice to LPC, in the event that the holder of any Other
Indebtedness or trustee in respect thereof seeks to accelerate the maturity of
any such Other Indebtedness or to enforce or exercise any remedies in respect
thereto.

         3. EFFECTIVE DATE.

                  This Agreement shall be deemed effective as of April 30, 2002.

have been duly authorized by all requisite action on its part; and (b) this

enforceability of creditors' rights generally or by general equitable
principles.

         5. NO OTHER AMENDMENTS.

                  Except as set forth herein, all terms and provisions of the
Loan Documents among Lender and LPC shall remain in full force and effect.
Except as expressly set forth herein, no other or further amendment, waiver or
