<PAGE>

         "Section 4.3 Covenants. The covenants set forth in the Credit Agreement
         which are applicable to the Guarantor as indicated therein are hereby
         incorporated into this Section 4.3 by reference and the Guarantor
         hereby agrees to comply with each such covenant which is applicable to
         the Guarantor. In addition to the foregoing, the Guarantor hereby
         covenants to comply with each of the covenants set forth in Sections
         7.9 (Mergers, Consolidations or Sales), 7.13 (Debt), 7.14 (Prepayment),
         7.17 (Business Conducted), 7.18 (Liens), 7.19 (Sale and Leaseback
         Transactions) and 7.20 (New Subsidiaries) of the Credit Agreement as if
         references to a "Borrower" thereunder were references to the Guarantor,
         and such covenants are hereby incorporated herein mutatis mutandis.
         Notwithstanding any of the foregoing, the Guarantor shall be permitted
         to (a) make loans to any Excess Collateral Provider; provided that such
         loans (i) are subordinated to the Guarantor's obligations hereunder
         pursuant to the terms of the Intercompany Subordination Agreement and
         (ii) are pledged to the Agent as additional security for the
         Guarantor's obligations hereunder; (b) incur Debt not to exceed
         $14,233,926, evidenced by three separate Master Promissory Notes,
         substantially in the form previously provided to the Agent, made by
         Parent in favor of A.I. Credit Corp. and each in the original principal
         amount of $4,744,642 (such notes, as amended or modified from time to
         time as permitted below are hereinafter referred to, individually and
         collectively, as the "Master Note"), the proceeds of which shall be
         used solely to pay premiums due and owing under each "Insurance Policy"
         (as defined in the Master Note); provided, that, (i) Guarantor may only
         make regularly scheduled payments of principal and interest in respect
         of such Debt in accordance with the terms of the Master Note
         (including, without limitation, payments upon receipt of proceeds of
         each "Insurance Policy" (as defined in the Master Note)), (ii)
         Guarantor shall not directly or indirectly (unless it has received the
         consent of the Required Lenders), (A) amend, modify, alter or change
         the terms of the Master Note or any other agreement, document or
         instrument related thereto as in effect on the date hereof except,
         that, Guarantor may, after prior written notice to Agent, amend,
         modify, alter or change the terms thereof so as to extend the maturity
         thereof, or defer the timing of any payments in respect thereof, or to
         forgive or cancel any portion of such Debt (other than pursuant to
         payments thereof), or to reduce the interest rate or any fees in
         connection therewith, or (B) redeem, retire, defease, purchase or
         otherwise acquire such Debt, or set aside or otherwise deposit or
         invest any sums for such purpose; provided, that such Debt may be
         retired with the proceeds of each "Insurance Policy" (as defined in the
         Master Note), and (iii) Guarantor shall furnish to Agent all notices of
         default or demands for payment in connection with such Debt received by
         Guarantor or on its behalf, promptly after the receipt thereof; (c)
         enter into each "Insurance Policy" (as defined in the Master Note)
         despite any prohibitions set forth in Section 7.10 of the Credit
         Agreement; and (d) create liens on (i) each "Insurance Policy" (as
         defined in the Master Note existing on the date hereof), (ii) the
         proceeds of such "Insurance Policy"; and (iii) a certificate of deposit
         in an amount not to exceed $90,000, plus interest thereon, issued by
         AIG Federal Savings Bank in the name of Guarantor, in each case to
         secure the Debt described in clause (b) above.

         2. AMENDMENTS TO SECURITY AGREEMENT. Subject to the terms and
conditions contained herein, the Security Agreement is hereby amended as
follows:

                  (a) Section 1 of the Security Agreement is hereby amended by
adding the following definitions in alphabetical order:

                           "Key Man Life Insurance Policies" means each
                  "Insurance Policy" as defined in each of the Master Promissory
                  Notes."

                           "Master Promissory Notes" means each of the Master
                  Promissory Notes, substantially in the form previously
                  provided to the Agent, made by Parent in favor of A.I. Credit
                  Corp. and each in the original principal amount of $4,744,642.

                  (b) Section 2(a) of the Security Agreement is hereby amended
by adding the following proviso at the end thereof:

                           "; provided, that notwithstanding the foregoing, in
                  no event shall (x) any of the Key Man Life Insurance Policies,
                  (y) any proceeds of any of the Key Man Life Insurance Policies
                  (and any investment earnings thereon), or (z) any segregated
                  Deposit Account holding solely the proceeds of such Key Man
                  Life Insurance Policies (and any investment earnings thereon),
                  be subject to any security interest or lien of the Agent or
                  any Lender pursuant to this Security Agreement or the other
                  Loan Documents."

                  (c) Section 3(m) of the Security Agreement is hereby amended
by adding a new sentence at the end thereof as follows:

                           "The foregoing shall not restrict the Parent Grantor
                  from entering into the Master Promissory Notes."

         3. CONDITIONS PRECEDENT. The effectiveness of the amendments contained
in Sections 1 and 2 above is subject to, and contingent upon, the satisfaction
of each of the following conditions precedent, each in form and substance
satisfactory to the Agent and the Required Lenders, unless the same shall
otherwise be waived in writing by the Agent and the Required Lenders in their
sole and absolute discretion:

thereunder after giving effect to this Amendment.

                  (b) Except as expressly provided herein, the execution,

warrants to the Agent and each Lender that: (a) this Amendment and the actions
on such Grantor's part contemplated hereby have been duly approved by all
requisite action on the part of such Grantor; (b) this Amendment and each of the
other documents executed and delivered by such Grantor in connection herewith

affecting creditors' rights generally, by general equitable principles or by
principles of good faith and fair dealing; and (c) that the execution, delivery
and performance of this Amendment and each of the other documents executed and

hereof, or any contracts or agreements to which such Grantor is a party or by
which any of its assets are bound. Each Grantor further hereby represents and

Loan Document.

         6. MISCELLANEOUS.

obligations hereunder without the prior written consent of the Agent and the
Required Lenders party hereto.

                  (b) This Amendment (together with the Guaranty and the
Security Agreement) constitutes the entire agreement between the parties with
respect to the subject matter hereof, and supersedes all prior negotiations,
representations, warranties, commitments, offers, letters of interest or intent,
