                            REIMBURSEMENT PROVISIONS


         Section 2.01. Reimbursement Obligations. The Companies jointly and
severally agree to pay the Blechmans all Reimbursement Obligations. Unless
otherwise specified herein, Reimbursement Obligations shall be due and payable
on demand. Amounts payable hereunder
<PAGE>   3
by the Companies shall be payable without offset or counterclaim of any kind.
Interest shall be payable on any and all Reimbursement Obligations from the date
such Reimbursement Obligations become payable until payment in full at a rate
per annum equal to the prime rate charged from time to time by Citibank N.A.

         Section 2.02. General Provisions as to Payments. The Companies shall
make each payment of Reimbursement Obligations in immediately available funds
not later than 1:00 p.m. (New York City time) on the date when due to the
Blechmans at the address for notice specified in Section 6.03. Any payment
received after 1:00 p.m. (New York City time) shall be deemed to have been made
on the next succeeding Business Day for all purposes. If any Reimbursement
Obligation shall be due on a day which is not a Business Day, it shall be made
on the next succeeding day which is a Business Day and such extension time shall
in such case be included in computing any interest if payable along with such
payment. All fees payable hereunder shall be computed on the basis of a 360-day
year and assessed for the actual number of days elapsed and interest shall be
computed on the basis of a 365/66-day year and assessed for the actual number of
days elapsed.

         Section 2.03. Obligations Absolute. The Companies' obligations under
this Agreement shall be absolute, unconditional and irrevocable, and shall be
discharged strictly in accordance with the terms hereof, under all circumstances
whatsoever, including, without limitation, the following circumstances:

                  (a) any lack of validity or enforceability of the Guaranty or
         any other agreement, instrument or document relating thereto;

                  (b) any amendment or waiver of or any consent to departure
         from the Guaranty;

                  (c) any other defense whatsoever that might constitute a
         defense available to, or discharge of, the Companies or the Blechmans;
         and

                  (d) the existence of any claim, setoff, defense or other
         rights which the Companies may have against the Blechmans or the
         Blechmans may have against CIT, whether in connection with this
         Agreement or any unrelated transaction;

                  (e) any other circumstance or happening whatsoever, whether or

payment in full of all Reimbursement Obligations, each of the Companies hereby
grants to the Blechmans a security interest in and to all of its right, title
and interest in and to the Collateral. The security interest granted to the

<PAGE>   4
security interest granted to CIT under the Financing Agreement in the manner
provided in the Intercreditor Agreement.

         Section 3.02. Covenants.

                  The Companies covenant to the Blechmans as follows:

                  (a) The Companies will, promptly upon request by the
         Blechmans, execute and deliver or use reasonable best efforts to give
         any notices, execute and file or procure any financing statements or
         other documents, all in form and substance reasonably satisfactory to
         the Blechmans, mark any chattel paper constituting Collateral, deliver
         any chattel paper or instruments constituting Collateral to the
         Blechmans and take any other actions that are necessary or, in the
         reasonable opinion of the Blechmans, desirable to perfect or continue
         the perfection and the priority of the Blechmans' security interest in
         the Collateral, to protect the Collateral against the rights, claims,
         or interests of third parties other than holders of Permitted Liens or
         to effect the purposes of this Agreement. The Companies hereby
         authorize the Blechmans to file any financing or continuation
         statements with respect to the Collateral without the signature of the
         Companies to the extent permitted by applicable law. The Companies will
         pay all reasonable costs incurred in connection with any of the
         foregoing.

                  (b) Except for the Permitted Liens, the Companies shall not
         directly or indirectly create, incur, assume or suffer to exist any
         Liens on or with respect to the Collateral.

         Section 3.03. Duty of Blechmans. The sole duty of the Blechmans with
respect to the custody, safekeeping and physical preservation of the Collateral
in their possession, under Section 9-207 of the UCC or otherwise, shall be to
comply with the specific duties and responsibilities set forth herein and to
exercise reasonable care to assure the safe custody of the Collateral. The
powers conferred on the Blechmans in this Agreement are solely for the
protection of their interests in the Collateral and shall not impose any duty
upon the Blechmans to exercise any such powers. None of the Blechmans shall be
liable for any action lawfully taken or omitted to be taken by any of them under
or in connection with the Collateral or this Agreement, except for their gross
negligence or willful misconduct.

                                  ARTICLE IV.

                              DEFAULTS AND REMEDIES

         material allegations of a petition filed against such Company in any
         bankruptcy, reorganization or insolvency proceeding or corporate action
         shall be taken by such Company for the purpose of effecting any of the
         foregoing or an order for relief under the federal Bankruptcy Code
         shall have been entered in respect of such Company or similar action
         shall have been taken or similar relief shall have been granted under
         the laws of any other country or jurisdiction;

                  (c) without the application, approval or consent of the
         Blechmans, a proceeding shall be instituted, in any court of competent
         jurisdiction, seeking in respect of any Company: adjudication in
         bankruptcy, reorganization, dissolution, winding up, liquidation, a
         composition or arrangement with creditors, a receiver, custodian,
         liquidator or the like of such Company or of all or any substantial
         part of its assets, or other like relief in respect of such Company
         unless such proceeding is being contested by it in good faith, and the
         same shall continue unstayed and in effect for any period of 60
         consecutive days; or

                  (d) any Default or Event of Default under the Financing
         Agreement (as such terms are defined in the Financing Agreement).

         Section 4.02. Remedies Upon Event of Default. If an Event of Default
occurs and is continuing, the Blechmans may, without notice to or demand upon

                  (a) declare all unpaid Reimbursement Obligations, together
         with the accrued interest thereon, to be, and the same shall thereupon
         become, immediately due and payable, without presentment, protest or

         waived by the Companies; or

                  (b) exercise their rights and remedies as a secured party
         under the UCC, including, without limitation, the right to take

                  (c) take any other action permitted to be taken by them under
         this Agreement or under applicable law.

                                   ARTICLE V.
