be evidenced within the provisions of the Loan Agreement, and, if required by
the holders of the Senior Debt, in a separate written subordination agreement
between the Secured Party and the holders of the Senior Debt.

      4. WARRANTIES AND COVENANTS. Borrower represents, warrants and covenants
to Secured Party as follows:

            (a) Except for the security interests granted hereby and any other
      security interests authorized by this Agreement or any other agreement
      between Borrower and Secured Party, Borrower is, or, as to Collateral to
      be acquired by Borrower after the date hereof, will be, the owner of the
      Collateral free from any adverse lien, security interest or encumbrance
      other than those identified on the attached EXHIBIT A; and Borrower agrees
      to defend the Collateral and proceeds thereof against any claims and
      demands of all persons at any time claiming the same or any interest
      therein.

            (b) The security interests hereby created are valid and Borrower has
      the authority and right to subject the Collateral to the security
      interests hereby created.

            (c) All financial statements, certificates and other information
      concerning the financial condition of Borrower, and proceeds hereafter
      furnished by Borrower to Secured Party shall be in all respects true and
      correct at the time the same are provided and shall be deemed, for all
      purposes, to have been furnished by Borrower to Secured Party for the
      purpose of obtaining credit or an extension of credit.

            (d) This Agreement has been duly executed and delivered by a duly
      authorized officer of Borrower and constitutes the legal, valid and
      binding obligation of Borrower, enforceable in accordance with its terms.


                                       3

            (e) Borrower does not conduct Borrower's business under any other
      name than that given above, and agrees not to change or reorganize the
      business entity under which it does business except upon the Secured
      Party's prior written approval.

            (f) There are no actions or proceedings either threatened or pending
      against Borrower which might result in any material adverse change in
      Borrower's financial condition or materially affect any of Borrower's
      assets.

All of Borrower's warranties contained in this Section 4 shall be continuing
warranties until Borrower has no remaining Obligations to Secured Party.

      5. LOSS OR DEPRECIATION OF COLLATERAL. Borrower shall immediately notify
Secured Party of any event causing a material loss or depreciation in value of
Collateral and the amount of such loss or depreciation.

      6. RECORDS, INSPECTION, AUDIT AND COVENANT FOR FURTHER ASSURANCES.

            (a) At the request of Secured Party, Borrower will advise Secured
      Party of the places where its books of Accounts and records, including all
      records of the Collateral and the dispositions made thereof by Borrower
      and of its Accounts and all collections thereon, are kept and maintained.

            (b) Borrower will keep and maintain such books and records with
      respect to the Collateral as Secured Party may from time to time
      reasonably prescribe for the purpose of enabling Secured Party to audit
      the same.

            (c) Borrower shall at all reasonable times and from time to time
      allow Secured Party, by or through any of its agents, attorneys or
      accountants, to examine or inspect the Collateral wherever located and to
      examine, inspect and make extracts from Borrower's books and records.
      Borrower shall do, make, execute and deliver all such additional and
      further acts, things, deeds, assurances and instruments as Secured Party
      may reasonably require, to assure to Secured Party its rights hereunder.

      7. PRESERVATION AND DISPOSITION OF THE COLLATERAL AND PROCEEDS.

            (a) Borrower will keep the Collateral in good condition and will not
      waste or destroy any of the same. Borrower will not use the Collateral in
      violation of any statute or ordinance.

            (b) Borrower will pay promptly when due all taxes, assessments and
      governmental charges upon or against the Collateral before the same become
      delinquent and before penalties accrue thereon.

            (c) At its option, Secured Party may discharge taxes, liens, other
      encumbrances or security interests not otherwise authorized by this
      Agreement or any other agreement between Borrower and Secured Party at any
      time levied or placed on the Collateral and may pay for the maintenance
      and preservation of the Collateral. Borrower agrees to reimburse


                                       4

      Secured Party, on demand, for any payment made or any expense incurred by
      Secured Party pursuant to the foregoing authorization.

            (d) Borrower, at its own expense, shall keep all of the Collateral
      fully insured against loss or damage by fire, theft, explosion, business
      interruption, and all other risks, in such amounts, with such companies,
      under such policies, and in such form as shall be satisfactory to Secured
      Party.

            (e) Borrower, unless in default, may use, consume and sell Inventory
      in carrying on its business in the ordinary course; but a sale in the
      ordinary course of business shall not include any transfer or sale in
      satisfaction, partial or complete, of a debt owed by Borrower. Borrower
      shall not, without the prior written consent of Secured Party, otherwise
      sell or dispose of the Collateral or any portion thereof.

      8. COLLECTIONS. In the absence of contrary instructions from Secured
Party, Borrower at its own expense shall take all necessary action promptly to
collect its Accounts and Loans. Upon an Event of Default, as such term is
defined in the Loan Agreement, and when and to the extent required by Secured
Party, Borrower shall (a) pay or deliver all cash proceeds of Accounts and Loans
to Secured Party immediately upon receipt in the exact form received without
commingling with other property, or (b) immediately upon receipt, deposit all
such proceeds in a collateral collection account established and controlled by
Secured Party at a financial institution of its choosing, and/or (c) notify
account borrowers that their accounts, Loans and/or contract rights (to the
extent included in Accounts) have been assigned to Secured Party and shall be
paid directly to Secured Party. At its option, at any time after an Event of
Default and at Borrower's expense, Secured Party may, in addition to its other
rights hereunder, sue, compromise on terms it considers proper, endorse, sell or
otherwise deal with the Accounts and Loans and proceeds of any Collateral either
in its own name or that of Borrower. After deduction of any expenses, including,
without limitation, attorneys fees and expenses, to the extent permitted under
applicable law, all proceeds received by Secured Party may be applied by Secured
Party to payment of any Obligations, if due, whether at maturity, by
acceleration or otherwise, in such order as Secured Party may choose. At any
time and from time to time, Secured Party may make like application of the
balance of the collateral collection account or it may release all or a part of
the balance to Borrower.

      9. ASSIGNMENTS, INVOICES AND INFORMATION. At Secured Party's request,
Borrower shall:

            (a) give Secured Party assignments in the form specified by Secured
      Party of specific Accounts and Loans as the Accounts and Loans arise;

            (b) furnish Secured Party with the original or a copy of invoices,
      and contracts applicable to each Account and Loan noting thereon, if
      Secured Party so requires, Secured Party's assignment and any additional
      statement required; and/or

            (c) notify Secured Party immediately if any Account or Loan arises
      out of a contract with the United States or any of its agencies and take
      any action required by Secured Party with reference to the Federal
      Assignment of Claims Act.


                                       5

      10. NOTATION OF ASSIGNMENT, INFORMATION AND PAYMENT OF ACCOUNTS. When and
to the extent required by Secured Party, Borrower shall:

            (a) mark records of Accounts, Loans and contract rights (to the
      extent included in Accounts) in a manner satisfactory to Secured Party to
      show Secured Party's interest therein;

            (b) furnish to Secured Party satisfactory evidence of performance of
      contracts and Loans; and

            (c) give Secured Party lists of account borrowers (showing names,
      addresses and amounts owing) and such other data concerning its Accounts
      and Loans as Secured Party may from time to time specify.

      11. FINANCING STATEMENTS; PERFECTION.

            (a) Borrower irrevocably authorizes Secured Party to prepare and
      file any financing statement, amendments, continuations, and all other
      documents, as Secured Party deems necessary to perfect and maintain the
      security interest and lien granted herein. This authorization shall remain
      in full force and effect and may be relied on by Secured Party as long as
      any Obligations remain outstanding.

            (b) Borrower agrees to promptly execute and deliver to Secured
      Party, concurrently with this Agreement and at any time thereafter, at
      Secured Party's request, all financing statements, assignments, promissory
      notes, certificates of title, affidavits, reports, notices, schedules of
      Accounts, designations of Inventory, letters of authority, stock
      certificates and any and all other documents and agreements, in form
      satisfactory to Secured Party, to perfect and maintain its security
      interest in the Collateral.

            (c) Except as otherwise provided in this Agreement or any other
      agreement between Borrower and Secured Party, without the prior written
      consent of Secured Party, Borrower will not allow or suffer any adverse
      financing statement covering the Collateral, or any portion thereof, to be
      on file in any public office.

      12. RIGHTS AND REMEDIES ON DEFAULT. Upon the occurrence of any Event of
Default, and at any time thereafter, Secured Party shall have the rights and
remedies of a secured party under the Code in addition to the rights and
remedies provided herein or in any other instrument or agreement executed by
Borrower.

      Without limiting the generality of the foregoing, Borrower expressly
agrees that in any such event Secured Party, without demand of performance or
other demand, advertisement or notice of any kind (except the notice specified
below of time and place of public or private sale) to or upon Borrower or any
other person (all and each of which demands, advertisements and/or notices are
hereby expressly waived), may forthwith collect, receive, appropriate and
realize upon the Collateral, or any part thereof, and/or may forthwith sell,
lease, assign, give an option or options to purchase or sell or otherwise
dispose of and deliver the Collateral (or contract to do so), or any part


                                       6

thereof, in one or more parcels at public or private sale or sales, at any
exchange broker's board or at any of Secured Party's offices or elsewhere at
such prices as Secured Party may deem best, for cash or on credit or for future
delivery without assumption of any credit risk. Secured Party shall have the
right upon any such public sale or sales and, to the extent permitted by law,
upon any such private sale or sales, to purchase the whole or any part of the
Collateral so sold, free of any right of equity of redemption, which equity of
redemption Borrower hereby releases. Secured Party may require Borrower to
assemble the Collateral and proceeds and make them available to Secured Party at
a place to be designated by Secured Party which is reasonably convenient to all
parties.

      Secured Party shall apply the net proceeds of any such collection,
recovery, receipt, appropriation, realization or sale after deducting all
reasonable costs and expenses of every kind incurred therein or incidental to
the care, safe-keeping or otherwise of any or all of the Collateral or in any
way relating to the rights of Secured Party hereunder, including, without
limitation, reasonable attorneys fees and expenses, to the payment in whole or
in part of the Obligations, in such order as Secured Party may elect, Borrower
remaining liable for any deficiency remaining unpaid after such application, and
only after so paying over such net proceeds and after the payment by Secured
Party of any other amount required by any provision of law, need Secured Party
account for the surplus, if any, to Borrower. To the extent permitted by
applicable law, Borrower waives all claims, damages and demands against Secured
Party arising out of the repossession, retention or sale of the Collateral.
Unless the Collateral is perishable or threatens to decline speedily in value or
is of a type customarily sold on a recognized market, Secured Party will give
Borrower reasonable notice of the time and place of any public sale thereof or
of the time after which any private sale or other intended disposition thereof
is to be made. The requirement of reasonable notice shall be met if such notice
is mailed, postage prepaid, to the address of Borrower, at least ten (10) days
before the time of the sale or disposition. Borrower shall pay to Secured Party
on demand any and all expenses, including, without limitation, reasonable
attorneys fees and expenses, to the extent permitted under applicable law,
incurred or paid by Secured Party in protecting or enforcing the Obligations and
other rights of Secured Party hereunder including its rights to take possession
of Collateral and proceeds thereof.

      13. SECURED PARTY'S APPOINTMENT AS ATTORNEY-IN-FACT. Borrower hereby
irrevocably constitutes and appoints Secured Party, with full power of
substitution, as its true and lawful attorney-in-fact with full power and
authority in the place and stead of Borrower and in the name of Borrower or in
its own name, from time to time in the sole and absolute discretion of Secured
Party, for the purpose of carrying out the terms of this Agreement, to take any
and all appropriate action and to execute any and all documents and instruments,
including without limitation, any financing statements necessary or helpful to
perfect or continue Secured Party's security interest in the Collateral, which
may be necessary or desirable to accomplish the purposes of this Agreement. This
power of attorney being coupled by an interest shall be irrevocable so long as
any Obligations remain unpaid. All acts of any such attorney are ratified and
approved, and except for willful misconduct, he or she will not be liable for
any act or omission or for any error of judgment or mistake of law.

      14. SECURITY NOT CONTINGENT. Secured Party's rights under this Agreement
shall not be contingent upon the exercise or enforcement by Secured Party of any
other rights or remedies he may have against Borrower or others. No election by
Secured Party to proceed in one form of


                                       7

action or proceeding, or against any party, or on any obligation, shall
constitute a waiver of Secured Party's right to enforce its rights under this
Agreement.

      15. GENERAL. Secured Party shall not be deemed to have waived any of its
rights hereunder or under any other agreement or instrument signed by Borrower
unless such waiver be in writing and signed by Secured Party. No delay or
omission on the part of Secured Party in exercising any right shall operate as a
waiver of such right or any other right. A waiver on any one occasion shall not
be construed as a bar to or waiver of any right or remedy on any future
occasion. All of Secured Party's rights and remedies, whether evidenced hereby
or by any other agreement or instrument, shall be cumulative and may be
exercised singularly or concurrently. Any demand upon or notice to Borrower that
Secured Party may elect to give shall be effective when deposited in the mails
addressed to Borrower at its principal place of business. Demands or notices
addressed to Borrower's address at which Secured Party customarily communicates
with Borrower shall also be effective. This Agreement shall be terminated only
by the filing of a termination statement in accordance with the applicable
provisions of the Code and/or when there are no outstanding Obligations and no
commitments on the part of Borrower to Secured Party under any agreement which
might give rise to any Obligations. Prior to such termination this shall be a
continuing agreement in every respect. This Agreement and all rights and
obligations hereunder including matters of construction, validity and
performance, shall be governed by the laws of the State of Michigan. This
Agreement is intended to take effect when signed by Borrower and delivered to
Secured Party. This Agreement may be executed in counterparts, each of which
shall be deemed to be an original and all of which together shall constitute one
instrument. Facsimile copies of signatures to this Agreement shall be deemed to
be originals, and the parties may rely upon such facsimile copies to the same
extent as the originals.
