Borrower's failure to deliver the compliance certificate described in Section
7.1.1(b) of the Credit Agreement with respect to Fiscal Year 1995, in each case
within the time frames therein specified; provided, however, that the Lenders
hereby waive (a) such noncompliance with Section 7.1.1(b) until the earlier of
two (2) days after filing such annual report and such compliance certificate
with the Securities and Exchange Commission or May 2, 1996 and (b) such
noncompliance with Section 7.1.7 of the Credit Agreement until August 15, 1996.
The foregoing notwithstanding, however, failure to deliver such annual audit
report and such compliance certificate within two (2) days of filing the same
with the Securities and Exchange Commission, but in no event later than May 2,
1996, and/or failure to deliver to the Agent a duly executed environmental
questionnaire as described above on or before August 15, 1996 shall constitute
an Event of Default under the Credit Agreement, as amended by the Second
Amendment. Except as noted in the immediately preceding sentence of this
Section 26, nothing contained in this Amendment shall be deemed to be a waiver
or abandonment of any rights or remedies available to the Lenders or the Agent
under the Credit Agreement, applicable law or otherwise nor a waiver of any
Default or Event of Default known or unknown, which may be currently existing
or which may occur in the future. The Agent and Lenders specifically reserve
all their rights and remedies including, without limitation, the right to
declare all Loans and other Obligations immediately due and payable with
respect to any Events of Default which have not been specifically waived
herein.

         SECTION 27.      Conditions Precedent; Effectiveness. The
effectiveness of this Amendment is conditioned upon receipt by the Agent on or
prior to April 30, 1996 of

                 (i)      counterparts hereof duly executed and delivered by
         the Borrower and each of the Lenders;

                 (ii)     the Term Notes for the account of Lenders duly
         executed and delivered by the Borrower;

         Security Agreement, each in form and substance satisfactory to the
         Agent and each duly executed by the Borrower, together with duly
         executed UCC-1 financing statements (the "Financing Statements")
         evidencing Liens on substantially all personal property of the

         create a first priority perfected Lien (subject to the Permitted
         Liens, as defined in the Security Agreement) in favor of the Secured
         Parties on substantially all the Assets of the Borrower (provided that
         such Liens may be pari passu with the liens securing the John Hancock
         Notes,) in each case in form and substance satisfactory to the Agent
         in its sole discretion, together with evidence of the completion (or
         satisfactory arrangements for the completion) of all recordings and
         filings of the Mortgages, the Security Agreement and the Financing
         Statements as may be necessary or, in the reasonable opinion of the
         Agent and Collateral Agent, desirable effectively to create a valid,
         perfected first priority Lien (subject to the Permitted Liens, as
         defined in the Security Agreement) against the properties purported to
         be covered thereby (provided that such Liens may be pari passu with
         the liens securing the John Hancock Notes); provided further that it
         is understood that the property and Assets covered by the Liens in
         this clause (iii) have a fair market value in the aggregate of such
         property and Assets not in excess of $1,000,000;

                 (iv)     an opinion of McAfee & Taft as counsel to the
         Borrower in form and substance satisfactory to the Agent;

                 (v)      an opinion from local counsel in each state where a

         the Financing Statements in favor of the Collateral Agent for the
         benefit of the Secured Parties and to all future such Liens as may be
         required pursuant to the terms of the Credit Agreement as amended
         hereby, and to all other transactions set forth herein, together with
         copies of all Liens granted to secure the John Hancock Notes which





                                       18
   19
         Liens shall be in form and substance satisfactory to the Agent, and an
         intercreditor agreement in form and substance satisfactory to the
         Agent duly executed and delivered by the owner and holder of the John
         Hancock Notes;

                 (vii)    a waiver in form and substance satisfactory to the
         Agent duly executed by John Hancock Life Insurance Company of all
         defaults and events of default under the John Hancock Notes or the
         John Hancock Note Agreement;

                 (viii)   a certificate of a Secretary or Assistant Secretary
         of the Borrower in form and substance satisfactory to the Agent (A) as

         Security Agreement and the Financing Statements describe all the
         Assets of the Borrower other than Assets having a fair market value in
         the aggregate of all such Assets not in excess of $1,000,000;

                 (ix)     payment of the fee described in Section 10 of the
         Second Amendment and of all reimbursable costs and expenses of the
         Lenders and the Agents including legal fees and charges billed prior

         Agent shall reasonably require; and

                 (xii)    all conditions to a Borrowing shall have been
         satisfied as of the date of the effectiveness of this Amendment.

         SECTION 28.      Effect of Amendment. This Amendment shall be deemed
to be an amendment to the Credit Agreement, and the Credit Agreement, as
amended hereby, is hereby ratified, approved and confirmed in each and every
respect. All references to the Credit Agreement in any other document,
instrument, agreement or writing shall hereafter be deemed to refer to the

be interpreted in such manner as to be effective and valid under applicable

prohibition or invalidity, without invalidating the remainder of such provision
or the remaining provisions of this Amendment.

         SECTION 32.      Entire Agreement. This Amendment, together with the
Credit Agreement and the other Loan Documents, constitutes the entire
understanding among the parties hereto with respect to the subject matter
hereof and supersedes any prior agreements, written or oral, with respect
thereto.

         THIS WRITTEN AMENDMENT TOGETHER WITH THE CREDIT AGREEMENT AND THE
OTHER LOAN DOCUMENTS REPRESENTS THE FINAL AGREEMENT AMONG THE PARTIES AND MAY
NOT BE CONTRADICTED BY EVIDENCE OF PRIOR, CONTEMPORANEOUS, OR SUBSEQUENT
AGREEMENTS OF THE PARTIES.
