fail to pay any of such amounts when and as the same shall be due and payable,
or shall fail to perform and discharge any covenant, representation or warranty
in accordance with the terms of the Notes, the Credit Agreement, or any of the
other Loan Documents (subject, in each case, to any applicable periods of grace
or cure), it will forthwith pay to the Agent, on behalf of the Banks, an amount
equal to any such amount and will pay any and all damages that may be incurred
or suffered in consequence thereof by Agent or any of the Banks and all
reasonable expenses, including reasonable attorneys' fees, that may be incurred
by Agent in enforcing such covenant, representation or warranty of Borrower, or
such Account Party and in enforcing the covenants and agreements of this
Guaranty.

     3.   Unconditional Character of Guaranty. The obligations of each Guarantor
under this Guaranty shall be absolute and unconditional, and shall be a guaranty
of payment and not of collection, irrespective of the validity, regularity or
enforceability of the Notes, the Credit Agreement, the Letter of Credit
Agreements, the Letters of Credit or any of the other Loan Documents, or any
provision thereof, the absence of any action to enforce the same, any waiver or
consent with respect to or any amendment of any provision thereof, the recovery
of any judgment against any Person or action to enforce the same, any failure or
delay in the enforcement of the obligations of Borrower or any Account Party
under the Notes, the Credit Agreement, or any of the other Loan Documents, or
any setoff, counterclaim, recoupment, limitation, defense or termination,
whether with or without notice to any of the Guarantors. Each of the Guarantors
hereby waives diligence, demand for payment, filing of claims with any court,
any proceeding to enforce any provision of the Notes executed by Borrower, or
the Credit Agreement, the Letter of Credit Agreements, the Letters of Credit or
any of the other Loan Documents, any right to require a proceeding first against
Borrower, any Account Party, or against any other guarantor or other party
providing collateral, or to exhaust any security for the performance of the
obligations of Borrower or any Account Party, any protest, presentment, notice
or demand whatsoever, and each of the Guarantors hereby covenants that this
Guaranty shall not be terminated, discharged or released except, subject to
Section 6.8 hereof, upon final payment in full subject to no revocation or
rescission of all amounts due and to 

                                       3
<PAGE>
 
become due from Borrower or any Account Party, as and to the extent described in
Section 2 above, and only to the extent of any such payment, performance and
discharge. Each of the Guarantors further covenants that no security now or
subsequently held by the Agent or the Banks for the payment of the Indebtedness
evidenced by the Notes made by Borrower under the Credit Agreement, or for the
payment of any other Indebtedness of Borrower or any Account Party to the Agent
or the Banks under the Credit Agreement, any Letter of Credit Agreement or
Letter of Credit or the other Loan Documents, whether in the nature of a
security interest, pledge, lien, assignment, setoff, suretyship, guaranty,
indemnity, insurance or otherwise, and no act, omission or other conduct of
Agent or the Banks in respect of such security (excluding fraud, gross
negligence or willful misconduct), shall affect in any manner whatsoever the
unconditional obligation of this Guaranty, and that Agent and each of the Banks,
in their respective sole discretion and without notice to any of the Guarantors,
may release, exchange, enforce, apply the proceeds of and otherwise deal with
any such security without affecting in any manner the unconditional obligation
of this Guaranty.

     Without limiting the generality of the foregoing, such obligations, and the
rights of the Agent to enforce the same on behalf of the Banks, by proceedings,
whether by action at law, suit in equity or otherwise, shall not be in any way
affected by (i) any insolvency, bankruptcy, liquidation, reorganization,
readjustment, composition, dissolution, winding up or other proceeding involving
or affecting Borrower or any Account Party or others, or (ii) any change in the
ownership of any of the capital stock of Borrower, any Account Party or any
other party providing collateral for any indebtedness covered by this Guaranty,
or any of their respective Affiliates.

     Each of the Guarantors hereby waives to the fullest extent possible under
applicable law:

          (a) any defense based upon the doctrine of marshalling of assets or
upon an election of remedies by Agent or the Banks, including, without
limitation, an election to proceed by non-judicial rather than judicial
foreclosure;

          (b) any defense based upon any statute or rule of law which provides
that the obligation of a surety must be neither larger in amount nor in other
respects more burdensome than that of the principal;

          (c) any duty on the part of Agent or any of the Banks to disclose to
the Guarantors any facts Agent or the Banks may now or hereafter know about
Borrower or any Account Party regardless of 

                                       4
<PAGE>
 
whether Agent or any Bank has reason to believe that any such facts materially
increase the risk beyond that which each of the Guarantors intends to assume or
has reason to believe that such facts are unknown to any of the Guarantors or
has a reasonable opportunity to communicate such facts to the each of the
Guarantors, since each of the Guarantors acknowledges that it is fully
responsible for being and keeping informed of the financial condition of
Borrower and the Account Parties and of all circumstances bearing on the risk of
non-payment of any Indebtedness hereby guaranteed;

          (d) any claim for reimbursement, contribution, exoneration, indemnity
or subrogation, or any other similar claim, which any such Guarantor may have or
obtain against Borrower or any Account Party by reason of the existence of this
Guaranty, or by reason of the payment by any of the Guarantors of any
Indebtedness or the performance of this Guaranty or of any other Loan Documents;
and

          (e) any other event or action (excluding any of the Guarantors'
compliance with the provisions hereof) that would result in the discharge by
operation of law or otherwise of any of the Guarantors from the performance or
observance of any obligation, covenant or agreement contained in this Guaranty.

     The Agent and each of the Banks may deal with Borrower and the Account
Parties and any security held by them for the obligations of Borrower or the
Account Parties (as aforesaid), in the same manner and as freely as if this
Guaranty did not exist and Agent shall be entitled, on behalf of Banks, without
notice to any of the Guarantors, among other things, to grant to Borrower and
the Account Parties such extension or extensions of time to perform any act or
acts as may seem advisable to Agent (on behalf of the Banks) at any time and
from time to time, and to permit Borrower or the Account Parties to incur
additional indebtedness to Agent, the Banks, or any of them, without
terminating, affecting or impairing the validity or enforceability of this
Guaranty or the obligations of the Guarantors hereunder.

     The Agent may proceed, either in its own name (on behalf of the Banks) or
in the name of one or more of the Guarantors, or otherwise, to protect and
enforce any or all of its rights under this Guaranty by suit in equity, action
at law or by other appropriate proceedings, or to take any action authorized or
permitted under applicable law, and shall be entitled to require and enforce the
performance of all acts and things required to be performed hereunder by the
Guarantors. Each and every remedy of the Agent and of the Banks shall, to the
extent permitted by law, be 

                                       5
<PAGE>
 
cumulative and shall be in addition to any other remedy given hereunder or now
or hereafter existing at law or in equity.

     No waiver or release shall be deemed to have been made by the Agent or any
of the Banks of any of its rights hereunder unless the same shall be in writing
and signed by all of the Banks or on behalf of the Banks by the Agent, and any
such waiver shall be a waiver or release only with respect to the specific
matter involved and shall in no way impair the rights of the Agent or any of the
Banks or the obligations of the Guarantors under this Guaranty in any other
respect at any other time.

     At the option of the Agent, each of the Guarantors may be joined in any
action or proceeding commenced by the Agent against Borrower or any Account
Party or any of the other parties providing collateral for any indebtedness
covered by this Guaranty in connection with or based upon the Notes made by
Borrower, the Credit Agreement, the Letter of Credit Agreements, the Letters of
Credit or any of the other Loan Documents or other Indebtedness, or any
provision thereof, and recovery may be had against each of the Guarantors in
such action or proceeding or in any independent action or proceeding against
each of the Guarantors, without any requirement that the Agent or the Banks
first assert, prosecute or exhaust any remedy or claim against Borrower, any
Account Party and/or any other party providing collateral for any Indebtedness
covered by this Guaranty.

     As a separate, additional and continuing obligation, each of the Guarantors
unconditionally and irrevocably undertakes and agrees with Agent that, should
the amounts referred to in Section 2 of this Guaranty not be recoverable from
such Guarantor in its capacity as a guarantor under this Guaranty for any reason
whatsoever (including, without limitation, by reason of any provision of the
Notes, the Credit Agreement, any Letter of Credit Agreement or Letter of Credit,
or any of the other Loan Documents being or becoming void, unenforceable, or
otherwise invalid under any applicable law) then, notwithstanding any knowledge
thereof by Agent and the Banks or any of them at any time, such Guarantor as
sole, original and independent obligor, upon demand by Agent, will make payment
to Agent of all such amounts, by way of a full indemnity.

     4.   Benefit of the Credit. Each of the Guarantors is a Subsidiary of
Borrower.  The Borrower has requested that the Banks make credit available to it
primarily for the purposes of allowing Borrower to provide working capital to
its Subsidiaries and to provide a letter of credit facility for the issuance of
Letters of Credit for the benefit of Borrower and the Account Parties, including
the Guarantors. Each of Borrower and the Guarantors is 

                                       6
<PAGE>
 
expecting to derive benefit, directly or indirectly, from the credit extended by
the Banks to Borrower and the Account Parties.

     5.   Collateral for Guaranty. The obligations of the Guarantors under this
Guaranty shall be secured by the security agreements, collateral assignments,
and other Loan Documents executed and delivered to Agent, pursuant to the Credit
Agreement, together with such other Loan Documents as required to be executed
and delivered by one or more of the Guarantors concurrently with or subsequent
to the date hereof, all pursuant to the terms and conditions of the Credit
Agreement or any of the other Loan Documents.

     6.   Miscellaneous.

          6.1  Governing Law. This Guaranty has been delivered in Michigan and
shall be interpreted and the rights of the parties hereunder shall be determined
under the laws of, and be enforceable in, the State of Michigan.

          6.2  Severability. If any term or provision of this Guaranty or the
application thereof to any circumstance shall, to any extent, be invalid or
unenforceable, the remainder of this Guaranty, or the application of such term
or provision to circumstances other than those as to which it is held invalid or
unenforceable, shall not be affected thereby, and each term and provision of
this Guaranty shall be valid and enforceable to the fullest extent permitted by
law.

          6.3  Notice. All notices and other communications to be made or given
pursuant to this Guaranty shall be sufficient if made or given in writing and
shall be given by personal delivery, by mail, by reputable overnight courier, by

on the signature pages hereof or at such other address as may be designated by
such party in a notice to the other party that complies as to deliver with the
terms of this Section 6.3. Any notice, if personally delivered or if mailed and
properly addressed with postage prepaid and sent by registered or certified
mail, shall be deemed given when received or when delivery is refused; any
notice, if given to a reputable overnight courier and properly addressed, shall
be deemed given two (2) Business Days after the date on which it was sent,
unless it is actually received sooner by the named addressee; and any notice, if
transmitted by telex or facsimile, shall be deemed given when received
(answerback confirmed in the case of telexes and receipt confirmed in the case
of telecopies).

                                       7
<PAGE>
 
          6.4  Right of Offset. Each of the Guarantors acknowledges the rights
of the Agent and of each of the Banks, upon the occurrence and during the
continuance of an Event of Default, to offset against the Indebtedness of
Guarantors to the Banks under this Guaranty, any amount owing by the Agent or
the Banks, or either or any of them to any of the Guarantors, whether
represented by any deposit of any Guarantor with the Agent or any of the Banks
or otherwise.

          6.5  Right to Cure. Each of the Guarantors shall have the right to
cure any Event of Default under the Credit Agreement or the Loan Documents with
respect to obligations of Borrower or any Account Party thereunder; provided
that such cure is effected within the applicable grace period or period for
cure, if any; and provided further that such cure can be effected in compliance
with the Credit Agreement. Except to the extent of payments of principal,
interest and/or other sums actually received by the Agent (or the Banks)
pursuant to such cure, the exercise of such right to cure by any of the
Guarantors shall not reduce or otherwise affect the liability of such guarantor
or any of the other Guarantors under this Guaranty.

          6.6  Consent to Jurisdiction. Each of the Guarantors and Agent hereby
irrevocably submit to the non-exclusive jurisdiction of any United States
Federal or Michigan state court sitting in Detroit in any action or proceeding
arising out of or relating to this Guaranty and each of the Guarantors and Agent
hereby irrevocably agree that all claims in respect of such action or proceeding
may be heard and determined in any such United States Federal or Michigan state
court. Each of the Guarantors irrevocably consents to the service of any and all
process in any such action or proceeding brought in any court in or of the State
of Michigan by the delivery of copies of such process to each Guarantor at its
address specified on the signature page hereto or by certified mail directed to
such address or such other address as may be designated by Guarantor in a notice
to the other parties that complies as to delivery with the terms of Section 6.3.
Nothing in this Section shall affect the right of the Agent to serve process in
any other manner permitted by law or limit the right of the Agent to bring any
such action or proceeding against any of the Guarantors or any of its property
in the courts of any other jurisdiction. Each of the Guarantors hereby
irrevocably waives any objection to the laying of venue of any such suit or
proceeding in the above described courts.

          6.7  Amendments. The terms of this Guaranty may not be waived,
altered, modified, amended, supplemented or terminated in any manner whatsoever
except as provided herein and in accordance with the Credit Agreement. In
accordance with Section 8.16 of the 

                                       8
<PAGE>

an original signatory hereto) by executing and delivering to Agent and the Banks

"A".

          6.8  Release. Upon payment in full of the Indebtedness or the
satisfaction by Guarantors of their obligations hereunder and any Loan Documents
executed by any of the Guarantors pursuant to the Credit Agreement thereto, and
when Guarantors are no longer subject to any obligation hereunder or thereunder,
the Agent shall deliver to each of the Guarantors, upon written request
therefor, (i) a written release of this Guaranty and (ii) appropriate discharges
of any Collateral provided by such Guarantor for this Guaranty; provided however
that the effectiveness of this Guaranty and such Collateral shall continue or be
reinstated, as the case may be, in the event: (x) that any payment received or
credit given by the Agent or the Banks, or any of them, is returned, disgorged,
rescinded or required to be recontributed to any Person as an avoidable
preference, impermissible setoff, fraudulent conveyance, restoration of capital
or otherwise under any applicable state, federal or national law of any
jurisdiction, including without limitation laws pertaining to bankruptcy or
insolvency, and this Guaranty shall thereafter be enforceable against each of
the Guarantors as if such returned, disgorged, recontributed or rescinded
payment or credit had not been received or given by the Agent or the Banks, and
whether or not the Agent or any Bank relied upon such payment or credit or
changed its position as a consequence thereof or (y) that any liability is
imposed, or sought to be imposed against the Agent or the Banks, or any of them,
relating to the environmental condition of any of property mortgaged or pledged
to Agent on behalf of the Banks by any of the Guarantors, Borrower, or any other
party as collateral (in whole or part) for any indebtedness or obligation
evidenced or secured by this Guaranty, whether such condition, claim or matter
is known or unknown, now exists or subsequently arises (excluding only
conditions which arise from and after acquisition by Agent or any Bank of any
such property, in lieu of foreclosure or otherwise and not caused by Company,
any of its Subsidiaries or any of their agents, employees or representatives) in
which event this Guaranty shall thereafter be enforceable against each of the
Guarantors to the extent of all liabilities, and all reasonable costs and
expenses (including reasonable attorneys fees) incurred by Agent or Banks as the
direct or indirect result of any such environmental condition. For purposes of
this Guaranty "environmental condition" includes, without limitation, conditions

          6.9  Joint and Several Obligation, etc. The obligation of each of the
Guarantors under this Guaranty shall be several and also joint, each with all
and also each with any one or more of the others, and may be enforced against
each severally, any two or more jointly, or some severally and some jointly. Any
one or more of the Guarantors may be released from its obligations hereunder
with or without consideration for such release and the obligations of the other
Guarantors hereunder shall be in no way affected thereby. Agent, on behalf of
Banks, may fail or elect not to prove a claim against any bankrupt or insolvent
Guarantor and thereafter, Agent and the Bank may, without notice to any
Guarantors, extend or renew any part or all of any indebtedness of any of the
Guarantors, and may permit any of the Guarantors to incur additional
indebtedness, without affecting in any manner the unconditional obligation of
the remaining Guarantors. Such action shall not affect any right of contribution
among the Guarantors.

          6.10  Waiver of Jury Trial.  AGENT AND EACH OF THE GUARANTORS AFTER
CONSULTING OR HAVING HAD THE OPPORTUNITY TO CONSULT WITH COUNSEL, KNOWINGLY,

JURY IN ANY LITIGATION BASED UPON OR ARISING OUT OF THIS GUARANTY OR ANY RELATED
INSTRUMENT OR AGREEMENT OR ANY OF THE TRANSACTIONS CONTEMPLATED BY THIS GUARANTY
OR ANY COURSE OF CONDUCT, DEALING, STATEMENTS (WHETHER ORAL OR WRITTEN) OR
ACTION OF ANY OF THEM. NEITHER THE AGENT NOR ANY OF THE GUARANTORS SHALL SEEK TO
CONSOLIDATE, BY COUNTERCLAIM OR OTHERWISE, ANY SUCH ACTION IN WHICH A JURY TRIAL
HAS BEEN WAIVED WITH ANY OTHER ACTION IN WHICH A JURY TRIAL CANNOT BE OR HAS NOT
BEEN WAIVED. THESE PROVISIONS SHALL NOT BE DEEMED TO HAVE BEEN MODIFIED IN ANY
RESPECT OR RELINQUISHED BY THE AGENT OR ANY OF THE GUARANTORS EXCEPT BY A
WRITTEN INSTRUMENT EXECUTED BY ALL OF THEM.

                               JOINDER AGREEMENT
                               -----------------


     THIS JOINDER AGREEMENT is dated as of ______________, 199_ by
_____________________, a ______________________ corporation ("New Guarantor").

     WHEREAS, pursuant to Section 8.17 of that certain Third Amended and
Restated Credit Agreement dated as of January 16, 1996 (as amended, supplemented
or otherwise modified from time to time, the "Credit Agreement") by and among
R.J. Tower Corporation, a Michigan corporation ("Company"), the Banks signatory
thereto and Comerica Bank, as Agent for the Banks (in such capacity, "Agent"),
and pursuant to Section 6.7 of that certain Second Amended and Restated Guaranty
(Tower-Michigan Debt) dated as of May ___, 1996 (the "Guaranty") executed and
delivered by the Guarantors named therein ("Guarantors") in favor of Agent, for
and on behalf of the Banks, the New Guarantor must execute and deliver a joinder
agreement in accordance with the Credit Agreement and the Guaranty.

     NOW THEREFORE, as a further inducement to Banks to continue to provide
credit accommodations to Company and the Account Parties (as defined in the
Credit Agreement), New Guarantor hereby covenants and agrees as follows:

     1.   All capitalized terms used herein shall have the meanings assigned to
          them in the Credit Agreement unless expressly defined to the contrary.

     2.   New Guarantor hereby enters into this Joinder Agreement in order to
          comply with Section 8.17 of the Credit Agreement and Section 6.7 of
          the Guaranty and does so in consideration of the Advances made or to
          be made from time to time under the Credit Agreement (and the other
          Loan Documents, as defined in the Credit Agreement), from which New
          Guarantor shall derive direct and indirect benefit as with the other
          Guarantors (all as set forth and on the same basis as in the
          Guaranty).

     3.   New Guarantor shall be considered, and deemed to be, for all purposes
          of the Credit Agreement, the Guaranty and the other Loan Documents, a
          Guarantor under the Guaranty as fully as though New Guarantor had

Obligor.

     4.  NON-REMITTANCE BASIS LOANS. Unless Collateral Agent (acting in its sole
discretion following any Default) shall notify Obligor that the Liabilities
shall henceforth be on a Remittance Basis, Obligor:

          (a)  will, at its own expense, endeavor to collect, as and when due,
               all amounts due Obligor under the Collateral, including the
               taking of such action with respect to such collection as
               Collateral Agent may reasonably request, or in the absence of
               such request, as Obligor may deem advisable, and may use such
               amounts collected in the ordinary course of its business, and

          (b)  may, in the ordinary course of business, grant to any party
               obligated on any of the Collateral, any rebate, refund or
               adjustment to which such party may be lawfully entitled, may
               accept, in connection therewith, the return of goods, the sale or
               lease of which shall have given rise to such Collateral, and may
               dispose of such returned goods.

     5.   REMITTANCE BASIS LOANS. If Collateral Agent shall notify Obligor at
any time following the occurrence of any Default that the Liabilities shall
henceforth be on a Remittance Basis:

          (a)  Unless Collateral Agent otherwise agrees in writing, Obligor
               shall at its sole expense establish and maintain, during the
               entire term of this Security Agreement (or until Collateral Agent

                                       6
<PAGE>
 
               acting in its sole discretion, shall notify Obligor that the
               Liabilities are no longer required to be on a Remittance Basis) a
               United States post office lock box (the "Lock Box"), to which
               Collateral Agent shall have exclusive access, and to which
               Obligor shall have no access. Obligor expressly authorizes
               Collateral Agent, from time to time, to remove all contents from
               the Lock Box, for disposition in accordance with this Security
               Agreement and the Intercreditor Agreement. Obligor agrees to
               notify all Account Debtors and other parties obligated to it that
               all payments made on any account, invoice or other Collateral
               (other than payments by electronic funds transfers) shall be
               remitted, for the credit of Borrower, to the Lock Box, and
               Obligor shall include a like statement on all invoices. Payments
               made by electronic funds transfer shall be made directly to the
               Cash Collateral Account (defined below), and Obligor shall so
               instruct its Account Debtors and other parties obligated to it.
               Obligor further shall execute all documents, authorizations and
               other agreements necessary to establish the Lock Box, and
               Collateral Agent's exclusive access thereto.

          (b)  Whether or not Obligor is required by Collateral Agent to
               maintain a Lock Box under this paragraph, any and all cash,
               checks, drafts and other instruments for the payment of money
               received by Obligor at any time, in full or partial payment of
               any of the Collateral (properly endorsed, where required, so that
               such items may be collected by Collateral Agent), shall
               forthwith, upon receipt, be transmitted and delivered to
               Collateral Agent in the form received. Any such items received by
               Obligor shall not be commingled with any other of Obligor's funds
               or property, but will be held separate and apart from Obligor's
               own funds or property, and upon express trust for the benefit of
               Collateral Agent until delivery is made to Collateral Agent.

          (c)  All items or amounts which are remitted to the Lock Box or
               otherwise delivered by or for the benefit of Obligor to
               Collateral Agent on account of partial or full payment of, or any
               other amount payable with respect to, any of the Collateral
               shall, at 

                                       7
<PAGE>
 
               the option of the Collateral Agent and subject to the terms of
               the Intercreditor Agreement, (i) be applied to the payment of the
               Liabilities, whether then due or not, in such order of
               application as set forth in the Intercreditor Agreement, or, (ii)
               shall be deposited to the credit of a non-interest bearing
               deposit account (the "Cash Collateral Account") to be established
               by Obligor with Collateral Agent pursuant to this paragraph, as
               security for payment of the Liabilities. Obligor shall have no
               right whatsoever to withdraw any funds so deposited. Obligor
               further grants to Collateral Agent, for the equal and ratable
               benefit of the Lenders, a first security interest in and lien on
               all funds on deposit in such account. Collateral Agent shall, on
               a daily basis (to the extent Collateral Agent is open for the
               conduct of full banking business), apply any collected funds in
               the Cash Collateral Account toward payment of the Liabilities,
               whether or not then due, in such order of application as set
               forth in the Intercreditor Agreement. To the extent collected
               funds remain at any time on deposit in the Cash Collateral
               Account after payment and discharge in full of the Liabilities
               (provided there is then no Default hereunder), Collateral Agent
               shall release such surplus collected funds to Obligor. Obligor
               hereby irrevocably authorizes and directs Collateral Agent to
               endorse all items received for deposit to the Cash Collateral
               Account, notwithstanding the inclusion on any such item of a
               restrictive notation, e.g., "paid in full", "balance of account",
               or other restriction.

          (d)  Obligor agrees that neither Collateral Agent nor any of the
               Lenders shall be liable for any loss or damage which Obligor
               suffers or may suffer as a result of Collateral Agent's
               processing of items or its exercise of any other rights or
               remedies under this Security Agreement, including without
               limitation indirect, special or consequential damages, loss of
               revenues or profits, or any claim, demand or action by any third
               party arising out of or in connection with the processing of
               items or the exercise of any other rights or remedies hereunder.
               Obligor further agrees to indemnify and hold Collateral Agent and
               each of the Lenders harmless from and against all such third
               party 

                                       8
<PAGE>
 
               claims, demands or actions, including without limitation
               litigation costs and reasonable attorney fees, provided, however,
               the Obligor shall not be obligated to indemnify Collateral Agent
               or any Lender with respect to any such claims, demands or actions
               arising solely as a result of the gross negligence or willful
               misconduct of the Collateral Agent or such Lender, respectively.

     6.   AGREEMENTS OF OBLIGOR. Obligor will:

          (a)  take or cause to be taken and execute or cause to be executed all
               financing statements, endorsements, assignments and other
               writings and do such other acts and things as Collateral Agent or
               Majority Lenders may from time to time reasonably request to
               establish, maintain and/or continue the perfected and first
               priority status of the security interest of Collateral Agent in
               the Collateral (free of all other liens (other than Permitted
               Liens) and claims whatsoever) to secure payment of the
               Liabilities or to implement or further effectuate the terms or
               purpose of this Security Agreement, and will on demand pay all
               costs and expenses of filing and recording, including the costs
               of any record searches, deemed necessary by Collateral Agent from
               time to time, to establish or determine the validity and the
               priority of Collateral Agent's security interest. Obligor further
               makes, constitutes and appoints Collateral Agent its true and
               lawful attorney-in-fact with full power of substitution to take
               any action in furtherance of this Security Agreement, including,
               but not limited to, the signing of financing statements,
               endorsing of instruments, and the execution and delivery of all
               documents and agreements necessary to obtain or accomplish any
               protection for or collection or disposition of any part of the
               Collateral. Such appointment shall be deemed irrevocable and
               coupled with an interest and may be exercised solely following
               the occurrence and during the continuance of a Default hereunder;

          (b)  keep, at the address designated below for its records, all
               records concerning the Collateral, which records will be of such
               character as will enable Collateral Agent or its designees to
               determine at any time the status of the Collateral, 

                                       9
<PAGE>
 
               and Obligor will not, unless Collateral Agent shall otherwise
               consent in Section 10 below or other writing, duplicate any such
               records at any other address;

          (c)  give Collateral Agent not less than 30 days prior written notice
               of all contemplated changes in Obligor's name, legal structure,
               or chief executive office, or in the location of the Collateral
               or Obligor's records concerning same and, prior to making any
               such changes, file or cause to be filed all financing statements
               or amendments necessary or appropriate to establish and maintain
               a valid first priority security interest in all the Collateral
               for Collateral Agent;

          (d)  furnish Collateral Agent such information concerning Obligor, the
               Collateral and the Account Debtors as Collateral Agent may from
               time to time reasonably request, including but not limited to
               agings of the Accounts and schedules, certificates and reports
               respecting the Collateral in such form and detail as Collateral
               Agent may specify;

          (e)  permit Collateral Agent and the Lenders and their designees at
               any time and from time to time during normal business hours upon
               reasonable notice, to inspect the Collateral and to inspect,
               audit and make copies of and extracts from all records and all
               other papers in the possession of Obligor pertaining to the
               Collateral and the Account Debtors whether the same are located
               on Obligor's premises or elsewhere and to take any other
               reasonable actions necessary to confirm or ascertain the
               existence, condition and value of the Collateral; upon request of
               Collateral Agent, deliver to Collateral Agent all such records
               and papers; and permit Collateral Agent in accordance with its
               normal collateral audit procedures or at any time following the
               occurrence and during the continuance of a Default hereunder to
               obtain confirmations and information from the Account Debtors as
               to the Accounts and Chattel Paper and Obligor's performance with
               respect thereto;

          (f)  upon request of Collateral Agent at any time, or from time to
               time, stamp on the Chattel Paper and on Obligor's records
               concerning the other 

                                       10
<PAGE>
 
               Collateral, a notation, in form satisfactory to Collateral Agent,
               of the security interest of Collateral Agent hereunder;

          (g)  immediately upon Collateral Agent's request deliver to Collateral
               Agent, appropriately endorsed to the order of Collateral Agent,
               any Chattel Paper, note, trade acceptance, check, draft or other
               instrument or writing for the payment of money which shall be
               received by Obligor and which may at any time evidence any
               obligation to Obligor for payment for goods sold or leased or
               services rendered;

          (h)  not create or permit to exist any lien on or security interest in
               any Collateral (or any interest therein) to or in favor of anyone
               other than Collateral Agent and the Permitted Liens;

          (i)  not sell, lease, assign, dispose of or agree to dispose of or
               otherwise transfer any of the Collateral (or any interest
               therein) or remove the same from its present location as set
               forth in Section 10 or change the location of its chief executive
               office without the written consent of Collateral Agent, except,
               prior to any Default, for the sale or lease of Inventory in the
               ordinary course of its business and for new value, provided, that
               Collateral Agent shall not unreasonably withhold or delay its
               consent to any removal of the Collateral or change in the
               location of the chief executive office of Obligor and provided
               further that Obligor may without the consent of Collateral Agent
               sell, transfer or dispose of machinery and equipment which is
               obsolete or no longer used in the conduct of Obligor's business
               to the extent the book value of the machinery and equipment so
               disposed does not exceed $500,000 in the aggregate during any
               single calendar year and the net proceeds of such disposition are
               paid by Obligor to Collateral Agent for application to the
               Liabilities in such order and manner as provided in the
               Intercreditor Agreement;

          (j)  to the extent that a security interest in Inventory or Tangible
               Property is granted hereunder, keep such Collateral in good
               condition and protect such Collateral from loss, damage or
               deterioration and will not materially alter or modify such

                                       11
<PAGE>
 
               Collateral, and Obligor will maintain insurance on such
               Collateral with a company reasonably satisfactory to Collateral
               Agent against such risks and in such form and amounts as
               Collateral Agent may reasonably require (or if Collateral Agent
               shall make no specific requirement, against such risks and in
               such amounts as are customary and prudent for businesses similar
               to Obligor in size and nature and at least equal to the full
               insurable value thereof), such insurance to be payable to Obligor
               and Collateral Agent as their interests appear pursuant to loss
               payee and/or mortgagee clauses as specified by, and in form
               satisfactory to, Collateral Agent. All such insurance shall, by
               its terms, provide that no cancellation, lapse (including without
               limitation any lapse for non-payment of premiums) or material
               change in coverage shall become effective until thirty (30) days
               after receipt by Collateral Agent of written notice from the
               applicable carrier. Obligor further shall provide Collateral
               Agent with evidence satisfactory to Collateral Agent that Obligor
               is at all times in compliance with this paragraph. Upon the
               occurrence and during the continuance of a Default hereunder or
               if Obligor fails to do so diligently and in good faith as
               reasonably determined by Collateral Agent, Collateral Agent may
               act as Obligor's attorney-in-fact in obtaining, adjusting,
               settling and compromising such insurance and endorsing any
               drafts. If Obligor fails to provide insurance as above required,
               Collateral Agent may, at its option, purchase the same and the
               cost thereof (with interest thereon at the highest per annum rate
               of interest then borne by any part of the Liabilities) shall be
               added to the Liabilities secured hereby. The proceeds of any
               insurance on such Collateral may, at the Collateral Agent's
               option, be applied to replacement of such Collateral or payment
               of the Liabilities, whether due or not;

          (k)  pay all taxes and assessments applicable to the Collateral before
               the assessment of any penalties or interest by any taxing
               authority;

          (l)  reimburse Collateral Agent, on demand, for all costs and
               expenses, including without limitation reasonable attorneys' fees
               and legal expenses, 

                                       12
<PAGE>
 
               incurred by Collateral Agent in seeking to perfect, collect,
               administer, maintain or enforce any rights or remedies under this
               Security Agreement or in respect of the Collateral, the Lock Box
               or the Cash Collateral Account, or in connection with any audit
               or inspection of the Collateral, and in case of Default, incurred
               by Collateral Agent in collecting or attempting to collect the
               Liabilities or enforcing or attempting to enforce its rights and
               remedies hereunder;

          (m)  if any of the Collateral (or any records concerning the
               Collateral) is located or kept by Obligor on leased premises, (i)
               provide a complete and correct copy of all applicable leases to
               Collateral Agent, (ii) furnish or cause to be furnished to
               Collateral Agent from each landlord under such leases an estoppel
               certificate and acknowledgment in form satisfactory to Collateral
               Agent confirming the terms of all such leases and authorizing, on
               Default, Collateral Agent's entry on such premises to enforce its
               rights and remedies under this Security Agreement, and (iii)
               comply with all such leases. Obligor's rights under all such
               leases shall further be part of the Collateral, and included in
               the security interest granted to Collateral Agent hereunder;

          (n)  not use or permit the use of any of the Collateral for any
               unlawful purpose, and will register, use, operate and control the
               Collateral in accordance with statutes, laws, ordinances and
               regulations relating thereto. Obligor further shall comply in all
               material respects at all times with all federal, state and local
               environmental protection, toxic substance and other similar laws
               and regulations applicable to Obligor's business or to any of the
               Collateral or any premises where any of the Collateral is located
               (Obligor hereby representing and warranting that, to its
               knowledge, after due inquiry, as of the date hereof, it is in
               compliance with all such laws and regulations) where such failure
               to so comply would reasonably be likely to materially adversely
               effect its business or the value of its property or assets (taken
               as a whole), and hold harmless and indemnify Collateral Agent
               from and against any and all liability or claims asserted against
               or suffered by Collateral

                                       13
<PAGE>
 
               Agent as a result of any failure by Obligor to comply with this
               paragraph (or any misrepresentation or breach of warranty
               hereunder), such indemnity to survive any payoff and discharge of
               the Liabilities.

          (o)  promptly notify Collateral Agent of any after-acquired Collateral
               which may be or become fixtures under applicable law, and in such
               notice shall state the name(s) and address(es) of the owner(s) of
               such real estate if not owned by Obligor. Obligor, at the request
               of Collateral Agent, shall furnish Collateral Agent with consents
               or acknowledgments from all persons having an interest in the
               real estate (such as owners, mortgage holders and lessees,
               excluding, however holders of any mortgage which secures
               obligations with respect to the Indiana Bonds), consenting to
               Collateral Agent's security interest and acknowledging the
               priority of Collateral Agent's security interest or disclaiming
               any interest in any Collateral described in this paragraph or
               Section 3(h).

     7.   DEFAULT. There shall be a default ("Default") under this Security
Agreement if there shall occur an Event of Default (as such term is defined in
either of the Agreements).

     8.   REMEDIES UPON DEFAULT. Upon the occurrence of any Default hereunder,
then, or at any time thereafter, unless such Default is remedied, Collateral
Agent may, subject to the terms and conditions of the Intercreditor Agreement:

          (a) declare each of the Liabilities (notwithstanding any provisions
          thereof), without demand or notice of any kind, immediately due and
          payable;

          (b) without notice to Obligor, notify any parties obligated on any of
          the Collateral to make payment to Collateral Agent, for the ratable
          benefit of the Lenders, of any amounts due or to become due thereunder
          and enforce collection of any of the Collateral by suit or otherwise
          and surrender, release or exchange all or any part thereof, or
          compromise or extend or renew for any period (whether or not longer
          than the original period) any indebtedness thereunder or evidenced
          thereby. Upon request of Collateral Agent, Obligor will, at its own
          expense, notify all Account Debtors and any other parties obligated to
          Obligor on any of the 

                                       14
<PAGE>
 
          Collateral to make payment to Collateral Agent of any amounts due or
          to become due thereunder; and

          (c) take possession of the Collateral and any records concerning same
          wherever they may be found, with or without process of law, and at its
          option, apply any Collateral against the Liabilities or leave the
          Collateral on Obligor's premises (rendering it unusable by any
          reasonable means which causes no damage to the Collateral) and dispose
          of the Collateral from said premises. Further, if Collateral Agent so
          demands, Obligor will, at its own expense, forthwith assemble and
          deliver the Collateral or any designated portions thereof (and any
          records concerning same) to Collateral Agent at a place designated by
          Collateral Agent reasonably convenient for Obligor. Collateral Agent
          may, dispose of the Collateral or any portion thereof by public or
          private sale (and bid at such sale) or otherwise in any manner
          permitted by the Michigan Uniform Commercial Code or other applicable
          law. Obligor agrees that Collateral Agent shall have given reasonable
          and sufficient notice of such intended disposition if Collateral
          Agent, at least seven (7) days prior to the specified date of
          disposition, deposits in the mail a letter addressed to Obligor at the
          address indicated below, postage prepaid, giving notice of the time,
          place and manner of disposition, provided that Obligor agrees that
          Collateral Agent shall otherwise be subject to no obligation, express
          or implied, to give notice to Obligor of any action taken or withheld
          by Collateral Agent. Obligor further acknowledges and agrees that no
          such notice need be given by Collateral Agent if Collateral Agent in
          its sole discretion determines in good faith that the Collateral is
          perishable or threatens to decline speedily in value or is of a type
          customarily sold on a recognized market.

     Collateral Agent shall apply the proceeds of any collection or disposition
of the Collateral (i) to the reasonable expenses of retaking, conserving,
collecting (by suit or otherwise) holding, disposing, preparing for sale,
selling and the like, including reasonable attorneys' fees and legal expenses
incurred, and (ii) then to the satisfaction of the Liabilities to Collateral
Agent and the Lenders secured by the Collateral, the application of proceeds to
the Liabilities to be in such order and manner as set forth in the Intercreditor
Agreement. Collateral Agent shall not be required to examine into the validity
of or to exchange or to collect on any Collateral or to take any action
necessary to hold any corporation, 

                                       15
<PAGE>
 
issuer or other person or party liable on the Collateral; and diligence in
looking after, preserving, or acting with respect to the Collateral or
collecting the same is hereby waived by Obligor, Collateral Agent's sole duty
with respect thereto being limited to the exercise of reasonable custodial care
of any Collateral in its possession.

     9.   GENERAL. All notices hereunder shall be provided (and shall be deemed
given) in accordance with Section 11 of the Intercreditor Agreement.

     If Collateral Agent has been advised that any of the Collateral is being
acquired with any proceeds of the borrowings secured hereby, Collateral Agent is
hereby authorized to disburse said proceeds directly to the seller of the
Collateral.

     Obligor makes, constitutes and appoints Collateral Agent its true and
lawful attorney-in-fact with full power of substitution to take any action in
furtherance of this Security Agreement, including, but not limited to, the
signing of financing statements, endorsing of instruments, and the execution and
delivery of all documents and agreements necessary to obtain or accomplish any
protection for or collection or disposition of any part of the Collateral. Such
appointment shall be deemed irrevocable and coupled with an interest and may be
exercised solely following the occurrence and during the continuance of a
Default hereunder. Without limiting the foregoing Obligor hereby specifically
authorizes Collateral Agent to endorse, negotiate and reduce to cash in the name
of Obligor, any check or other item, howsoever received by Collateral Agent and
whether received before or after any Default, representing any payment on or
other proceeds of any of the Collateral.

     Collateral Agent shall not be required to examine into the validity of or
to exchange or to collect on any Collateral or to take any action necessary to
hold any corporation, issuer or other person or party liable on the Collateral;
and diligence in looking after, preserving, or acting with respect to the
Collateral or collecting the same is hereby waived by Obligor, Collateral
Agent's sole duty with respect thereto being limited to the exercise of
reasonable custodial care over any Collateral in its possession.

     No delay on the part of Collateral Agent or any Lender in the exercise of
any right or remedy shall operate as a waiver thereof, and no single or partial
exercise by Collateral Agent or any Lender of any right or remedy shall preclude
other or further exercise thereof or the exercise of any other right or remedy.

     4.  NON-REMITTANCE BASIS LOANS. Unless Collateral Agent (acting in its sole
discretion following any Default) shall notify Obligor that the Liabilities
shall henceforth be on a Remittance Basis, Obligor:

          (a)  will, at its own expense, endeavor to collect, as and when due, 
               all amounts due Obligor under the Collateral, including the
               taking of such action with respect to such collection as
               Collateral Agent may reasonably request, or in the absence of
               such request, as Obligor may deem advisable, and may use such
               amounts collected in the ordinary course of its business, and

          (b)  may, in the ordinary course of business, grant to any party
               obligated on any of the Collateral, any rebate, refund or
               adjustment to which such party may be lawfully entitled, may
               accept, in connection therewith, the return of goods, the sale or
               lease of which shall have given rise to such Collateral, and may
               dispose of such returned goods.

     5.   REMITTANCE BASIS LOANS. If Collateral Agent shall notify Obligor at
any time following the occurrence of any Default that the Liabilities shall
henceforth be on a Remittance Basis:

          (a)  Unless Collateral Agent otherwise agrees in writing, Obligor
               shall at its sole expense establish and maintain, during the
               entire term of this Security Agreement (or until Collateral Agent

                                       6
<PAGE>
 
               acting in its sole discretion, shall notify Obligor that the
               Liabilities are no longer required to be on a Remittance Basis) a
               United States post office lock box (the "Lock Box"), to which
               Collateral Agent shall have exclusive access, and to which
               Obligor shall have no access. Obligor expressly authorizes
               Collateral Agent, from time to time, to remove all contents from
               the Lock Box, for disposition in accordance with this Security
               Agreement and the Intercreditor Agreement. Obligor agrees to
               notify all Account Debtors and other parties obligated to it that
               all payments made on any account, invoice or other Collateral
               (other than payments by electronic funds transfers) shall be
               remitted, for the credit of Borrower, to the Lock Box, and
               Obligor shall include a like statement on all invoices. Payments
               made by electronic funds transfer shall be made directly to the
               Cash Collateral Account (defined below), and Obligor shall so
               instruct its Account Debtors and other parties obligated to it.
               Obligor further shall execute all documents, authorizations and
               other agreements necessary to establish the Lock Box, and
               Collateral Agent's exclusive access thereto.

          (b)  Whether or not Obligor is required by Collateral Agent to
               maintain a Lock Box under this paragraph, any and all cash,
               checks, drafts and other instruments for the payment of money
               received by Obligor at any time, in full or partial payment of
               any of the Collateral (properly endorsed, where required, so that
               such items may be collected by Collateral Agent), shall
               forthwith, upon receipt, be transmitted and delivered to
               Collateral Agent in the form received. Any such items received by
               Obligor shall not be commingled with any other of Obligor's funds
               or property, but will be held separate and apart from Obligor's
               own funds or property, and upon express trust for the benefit of
               Collateral Agent until delivery is made to Collateral Agent.

          (c)  All items or amounts which are remitted to the Lock Box or
               otherwise delivered by or for the benefit of Obligor to
               Collateral Agent on account of partial or full payment of, or any
               other amount payable with respect to, any of the Collateral
               shall, at 

                                       7
<PAGE>
 
               the option of the Collateral Agent and subject to the terms of
               the Intercreditor Agreement, (i) be applied to the payment of the
               Liabilities, whether then due or not, in such order of
               application as set forth in the Intercreditor Agreement, or, (ii)
               shall be deposited to the credit of a non-interest bearing
               deposit account (the "Cash Collateral Account") to be established
               by Obligor with Collateral Agent pursuant to this paragraph, as
               security for payment of the Liabilities. Obligor shall have no
               right whatsoever to withdraw any funds so deposited. Obligor
               further grants to Collateral Agent, for the equal and ratable
               benefit of the Lenders, a first security interest in and lien on
               all funds on deposit in such account. Collateral Agent shall, on
               a daily basis (to the extent Collateral Agent is open for the
               conduct of full banking business), apply any collected funds in
               the Cash Collateral Account toward payment of the Liabilities,
               whether or not then due, in such order of application as set
               forth in the Intercreditor Agreement. To the extent collected
               funds remain at any time on deposit in the Cash Collateral
               Account after payment and discharge in full of the Liabilities
               (provided there is then no Default hereunder), Collateral Agent
               shall release such surplus collected funds to Obligor. Obligor
               hereby irrevocably authorizes and directs Collateral Agent to
               endorse all items received for deposit to the Cash Collateral
               Account, notwithstanding the inclusion on any such item of a
               restrictive notation, e.g., "paid in full", "balance of account",
               or other restriction.

          (d)  Obligor agrees that neither Collateral Agent nor any of the
               Lenders shall be liable for any loss or damage which Obligor
               suffers or may suffer as a result of Collateral Agent's
               processing of items or its exercise of any other rights or
               remedies under this Security Agreement, including without
               limitation indirect, special or consequential damages, loss of
               revenues or profits, or any claim, demand or action by any third
               party arising out of or in connection with the processing of
               items or the exercise of any other rights or remedies hereunder.
               Obligor further agrees to indemnify and hold Collateral Agent and
               each of the Lenders harmless from and against all such third
               party

                                       8
<PAGE>
 
               claims, demands or actions, including without limitation
               litigation costs and reasonable attorney fees, provided, however,
               the Obligor shall not be obligated to indemnify Collateral Agent
               or any Lender with respect to any such claims, demands or actions
               arising solely as a result of the gross negligence or willful
               misconduct of the Collateral Agent or such Lender, respectively.

     6.   AGREEMENTS OF OBLIGOR. Obligor will:

          (a)  take or cause to be taken and execute or cause to be executed all
               financing statements, endorsements, assignments and other
               writings and do such other acts and things as Collateral Agent or
               Majority Lenders may from time to time reasonably request to
               establish, maintain and/or continue the perfected and first
               priority status of the security interest of Collateral Agent in
               the Collateral (free of all other liens (other than Permitted
               Liens) and claims whatsoever) to secure payment of the
               Liabilities or to implement or further effectuate the terms or
               purpose of this Security Agreement, and will on demand pay all
               costs and expenses of filing and recording, including the costs
               of any record searches, deemed necessary by Collateral Agent from
               time to time, to establish or determine the validity and the
               priority of Collateral Agent's security interest. Obligor further
               makes, constitutes and appoints Collateral Agent its true and
               lawful attorney-in-fact with full power of substitution to take
               any action in furtherance of this Security Agreement, including,
               but not limited to, the signing of financing statements,
               endorsing of instruments, and the execution and delivery of all
               documents and agreements necessary to obtain or accomplish any
               protection for or collection or disposition of any part of the
               Collateral. Such appointment shall be deemed irrevocable and
               coupled with an interest and may be exercised solely following
               the occurrence and during the continuance of a Default hereunder;

          (b)  keep, at the address designated below for its records, all
               records concerning the Collateral, which records will be of such
               character as will enable Collateral Agent or its designees to
               determine at any time the status of the Collateral, 

                                       9
<PAGE>
 
               and Obligor will not, unless Collateral Agent shall otherwise
               consent in Section 10 below or other writing, duplicate any such
               records at any other address;

          (c)  give Collateral Agent not less than 30 days prior written notice
               of all contemplated changes in Obligor's name, legal structure,
               or chief executive office, or in the location of the Collateral
               or Obligor's records concerning same and, prior to making any
               such changes, file or cause to be filed all financing statements
               or amendments necessary or appropriate to establish and maintain
               a valid first priority security interest in all the Collateral
               for Collateral Agent;

          (d)  furnish Collateral Agent such information concerning Obligor, the
               Collateral and the Account Debtors as Collateral Agent may from
               time to time reasonably request, including but not limited to
               agings of the Accounts and schedules, certificates and reports
               respecting the Collateral in such form and detail as Collateral
               Agent may specify;

          (e)  permit Collateral Agent and the Lenders and their designees at
               any time and from time to time during normal business hours upon
               reasonable notice, to inspect the Collateral and to inspect,
               audit and make copies of and extracts from all records and all
               other papers in the possession of Obligor pertaining to the
               Collateral and the Account Debtors whether the same are located
               on Obligor's premises or elsewhere and to take any other
               reasonable actions necessary to confirm or ascertain the
               existence, condition and value of the Collateral; upon request of
               Collateral Agent, deliver to Collateral Agent all such records
               and papers; and permit Collateral Agent in accordance with its
               normal collateral audit procedures or at any time following the
               occurrence and during the continuance of a Default hereunder to
               obtain confirmations and information from the Account Debtors as
               to the Accounts and Chattel Paper and Obligor's performance with
               respect thereto;

          (f)  upon request of Collateral Agent at any time, or from time to
               time, stamp on the Chattel Paper and on Obligor's records
               concerning the other 

                                       10
<PAGE>
 
               Collateral, a notation, in form satisfactory to Collateral Agent,
               of the security interest of Collateral Agent hereunder;

          (g)  immediately upon Collateral Agent's request deliver to Collateral
               Agent, appropriately endorsed to the order of Collateral Agent,
               any Chattel Paper, note, trade acceptance, check, draft or other
               instrument or writing for the payment of money which shall be
               received by Obligor and which may at any time evidence any
               obligation to Obligor for payment for goods sold or leased or
               services rendered;

          (h)  not create or permit to exist any lien on or security interest in
               any Collateral (or any interest therein) to or in favor of anyone
               other than Collateral Agent and the Permitted Liens;

          (i)  not sell, lease, assign, dispose of or agree to dispose of or
               otherwise transfer any of the Collateral (or any interest
               therein) or remove the same from its present location as set
               forth in Section 10 or change the location of its chief executive
               office without the written consent of Collateral Agent, except,
               prior to any Default, for the sale or lease of Inventory in the
               ordinary course of its business and for new value, provided, that
               Collateral Agent shall not unreasonably withhold or delay its
               consent to any removal of the Collateral or change in the
               location of the chief executive office of Obligor and provided
               further that Obligor may without the consent of Collateral Agent
               sell, transfer or dispose of machinery and equipment which is
               obsolete or no longer used in the conduct of Obligor's business
               to the extent the book value of the machinery and equipment so
               disposed does not exceed $500,000 in the aggregate during any
               single calendar year and the net proceeds of such disposition are
               paid by Obligor to Collateral Agent for application to the
               Liabilities in such order and manner as provided in the
               Intercreditor Agreement;

          (j)  to the extent that a security interest in Inventory or Tangible
               Property is granted hereunder, keep such Collateral in good
               condition and protect such Collateral from loss, damage or
               deterioration and will not materially alter or modify such

                                       11
<PAGE>
  
               Collateral, and Obligor will maintain insurance on such
               Collateral with a company reasonably satisfactory to Collateral
               Agent against such risks and in such form and amounts as
               Collateral Agent may reasonably require (or if Collateral Agent
               shall make no specific requirement, against such risks and in
               such amounts as are customary and prudent for businesses similar
               to Obligor in size and nature and at least equal to the full
               insurable value thereof), such insurance to be payable to Obligor
               and Collateral Agent as their interests appear pursuant to loss
               payee and/or mortgagee clauses as specified by, and in form
               satisfactory to, Collateral Agent. All such insurance shall, by
               its terms, provide that no cancellation, lapse (including without
               limitation any lapse for non-payment of premiums) or material
               change in coverage shall become effective until thirty (30) days
               after receipt by Collateral Agent of written notice from the
               applicable carrier. Obligor further shall provide Collateral
               Agent with evidence satisfactory to Collateral Agent that Obligor
               is at all times in compliance with this paragraph. Upon the
               occurrence and during the continuance of a Default hereunder or
               if Obligor fails to do so diligently and in good faith as
               reasonably determined by Collateral Agent, Collateral Agent may
               act as Obligor's attorney-in-fact in obtaining, adjusting,
               settling and compromising such insurance and endorsing any
               drafts. If Obligor fails to provide insurance as above required,
               Collateral Agent may, at its option, purchase the same and the
               cost thereof (with interest thereon at the highest per annum rate
               of interest then borne by any part of the Liabilities) shall be
               added to the Liabilities secured hereby. The proceeds of any
               insurance on such Collateral may, at the Collateral Agent's
               option, be applied to replacement of such Collateral or payment
               of the Liabilities, whether due or not;

          (k)  pay all taxes and assessments applicable to the Collateral before
               the assessment of any penalties or interest by any taxing
               authority;

          (l)  reimburse Collateral Agent, on demand, for all costs and
               expenses, including without limitation reasonable attorneys' fees
               and legal expenses,

                                       12
<PAGE>
 
               incurred by Collateral Agent in seeking to perfect, collect,
               administer, maintain or enforce any rights or remedies under this
               Security Agreement or in respect of the Collateral, the Lock Box
               or the Cash Collateral Account, or in connection with any audit
               or inspection of the Collateral, and in case of Default, incurred
               by Collateral Agent in collecting or attempting to collect the
               Liabilities or enforcing or attempting to enforce its rights and
               remedies hereunder;

          (m)  if any of the Collateral (or any records concerning the
               Collateral) is located or kept by Obligor on leased premises, (i)
               provide a complete and correct copy of all applicable leases to
               Collateral Agent, (ii) furnish or cause to be furnished to
               Collateral Agent from each landlord under such leases an estoppel
               certificate and acknowledgment in form satisfactory to Collateral
               Agent confirming the terms of all such leases and authorizing, on
               Default, Collateral Agent's entry on such premises to enforce its
               rights and remedies under this Security Agreement, and (iii)
               comply with all such leases. Obligor's rights under all such
               leases shall further be part of the Collateral, and included in
               the security interest granted to Collateral Agent hereunder;

          (n)  not use or permit the use of any of the Collateral for any
               unlawful purpose, and will register, use, operate and control the
               Collateral in accordance with statutes, laws, ordinances and
               regulations relating thereto. Obligor further shall comply in all
               material respects at all times with all federal, state and local
               environmental protection, toxic substance and other similar laws
               and regulations applicable to Obligor's business or to any of the
               Collateral or any premises where any of the Collateral is located
               (Obligor hereby representing and warranting that, to its
               knowledge, after due inquiry, as of the date hereof, it is in
               compliance with all such laws and regulations) where such failure
               to so comply would reasonably be likely to materially adversely
               effect its business or the value of its property or assets (taken
               as a whole), and hold harmless and indemnify Collateral Agent
               from and against any and all liability or claims asserted against
               or suffered by Collateral 

                                       13
<PAGE>
 
               Agent as a result of any failure by Obligor to comply with this
               paragraph (or any misrepresentation or breach of warranty
               hereunder), such indemnity to survive any payoff and discharge of
               the Liabilities.

          (o)  promptly notify Collateral Agent of any after-acquired Collateral
               which may be or become fixtures under applicable law, and in such
               notice shall state the name(s) and address(es) of the owner(s) of
               such real estate if not owned by Obligor. Obligor, at the request
               of Collateral Agent, shall furnish Collateral Agent with consents
               or acknowledgments from all persons having an interest in the
               real estate (such as owners, mortgage holders and lessees,
               excluding, however holders of any mortgage which secures
               obligations with respect to the Indiana Bonds), consenting to
               Collateral Agent's security interest and acknowledging the
               priority of Collateral Agent's security interest or disclaiming
               any interest in any Collateral described in this paragraph or
               Section 3(h).

     7.   DEFAULT. There shall be a default ("Default") under this Security
Agreement if there shall occur an Event of Default (as such term is defined in
either of the Agreements).

     8.   REMEDIES UPON DEFAULT. Upon the occurrence of any Default hereunder,
then, or at any time thereafter, unless such Default is remedied, Collateral
Agent may, subject to the terms and conditions of the Intercreditor Agreement:

          (a) declare each of the Liabilities (notwithstanding any provisions
          thereof), without demand or notice of any kind, immediately due and
          payable;

          (b) without notice to Obligor, notify any parties obligated on any of
          the Collateral to make payment to Collateral Agent, for the ratable
          benefit of the Lenders, of any amounts due or to become due thereunder
          and enforce collection of any of the Collateral by suit or otherwise
          and surrender, release or exchange all or any part thereof, or
          compromise or extend or renew for any period (whether or not longer
          than the original period) any indebtedness thereunder or evidenced
          thereby. Upon request of Collateral Agent, Obligor will, at its own
          expense, notify all Account Debtors and any other parties obligated to
          Obligor on any of the 

                                       14
<PAGE>
 
          Collateral to make payment to Collateral Agent of any amounts due or
          to become due thereunder; and

          (c) take possession of the Collateral and any records concerning same
          wherever they may be found, with or without process of law, and at its
          option, apply any Collateral against the Liabilities or leave the
          Collateral on Obligor's premises (rendering it unusable by any
          reasonable means which causes no damage to the Collateral) and dispose
          of the Collateral from said premises. Further, if Collateral Agent so
          demands, Obligor will, at its own expense, forthwith assemble and
          deliver the Collateral or any designated portions thereof (and any
          records concerning same) to Collateral Agent at a place designated by
          Collateral Agent reasonably convenient for Obligor. Collateral Agent
          may, dispose of the Collateral or any portion thereof by public or
          private sale (and bid at such sale) or otherwise in any manner
          permitted by the Michigan Uniform Commercial Code or other applicable
          law. Obligor agrees that Collateral Agent shall have given reasonable
          and sufficient notice of such intended disposition if Collateral
          Agent, at least seven (7) days prior to the specified date of
          disposition, deposits in the mail a letter addressed to Obligor at the
          address indicated below, postage prepaid, giving notice of the time,
          place and manner of disposition, provided that Obligor agrees that
          Collateral Agent shall otherwise be subject to no obligation, express
          or implied, to give notice to Obligor of any action taken or withheld
          by Collateral Agent. Obligor further acknowledges and agrees that no
          such notice need be given by Collateral Agent if Collateral Agent in
          its sole discretion determines in good faith that the Collateral is
          perishable or threatens to decline speedily in value or is of a type
          customarily sold on a recognized market.

     Collateral Agent shall apply the proceeds of any collection or disposition
of the Collateral (i) to the reasonable expenses of retaking, conserving,
collecting (by suit or otherwise) holding, disposing, preparing for sale,
selling and the like, including reasonable attorneys' fees and legal expenses
incurred, and (ii) then to the satisfaction of the Liabilities to Collateral
Agent and the Lenders secured by the Collateral, the application of proceeds to
the Liabilities to be in such order and manner as set forth in the Intercreditor
Agreement. Collateral Agent shall not be required to examine into the validity
of or to exchange or to collect on any Collateral or to take any action
necessary to hold any corporation, 

                                       15
<PAGE>
 
issuer or other person or party liable on the Collateral; and diligence in
looking after, preserving, or acting with respect to the Collateral or
collecting the same is hereby waived by Obligor, Collateral Agent's sole duty
with respect thereto being limited to the exercise of reasonable custodial care
of any Collateral in its possession.

     9.   GENERAL. All notices hereunder shall be provided (and shall be deemed
given) in accordance with Section 11 of the Intercreditor Agreement.

     If Collateral Agent has been advised that any of the Collateral is being
acquired with any proceeds of the borrowings secured hereby, Collateral Agent is
hereby authorized to disburse said proceeds directly to the seller of the
Collateral.

     Obligor makes, constitutes and appoints Collateral Agent its true and
lawful attorney-in-fact with full power of substitution to take any action in
furtherance of this Security Agreement, including, but not limited to, the
signing of financing statements, endorsing of instruments, and the execution and
delivery of all documents and agreements necessary to obtain or accomplish any
protection for or collection or disposition of any part of the Collateral. Such
appointment shall be deemed irrevocable and coupled with an interest and may be
exercised solely following the occurrence and during the continuance of a
Default hereunder. Without limiting the foregoing Obligor hereby specifically
authorizes Collateral Agent to endorse, negotiate and reduce to cash in the name
of Obligor, any check or other item, howsoever received by Collateral Agent and
whether received before or after any Default, representing any payment on or
other proceeds of any of the Collateral.

     Collateral Agent shall not be required to examine into the validity of or
to exchange or to collect on any Collateral or to take any action necessary to
hold any corporation, issuer or other person or party liable on the Collateral;

<PAGE>

       present or future operation of the land or any building or buildings now

       and to any equipment which may be subjected to any title retention or

       understood and agreed that all equipment is part and parcel of the
       mortgaged premises and appropriated to the use of the said real estate
       and, whether affixed or annexed or not, shall for the purposes of this
       Mortgage, unless the Mortgagee shall otherwise elect, be deemed
       conclusively to be real estate and mortgaged under this Mortgage; and

       attorneys fees, costs and disbursements incurred by the Mortgagee in
       connection with the collection of these awards or payments shall be
       additional Several Obligations secured by this Mortgage. The Mortgagor
       agrees to execute and deliver, from time to time, further instruments as
       reasonably may be requested by the Mortgagee to confirm the assignment to
       the Mortgagee, for the equal and ratable benefit of the Lenders, of these
       awards and payments.

Any reference in this Mortgage to the "mortgaged premises" shall, unless the
context requires otherwise, be deemed to include and 

                                       5
<PAGE>
 
apply to the above described land, buildings, improvements, equipment, rents,
issues, profits, leases, easements, tenements, hereditaments, and appurtenances,
awards, payments and all other rights, privileges and interests described above.
Without limiting in any way the Several Obligations secured by this Mortgage, it
is agreed that this Mortgage secures future advances under Act No. 348 of the
Michigan Public Acts, as amended. The Mortgagor, on a continuing basis,
warrants, covenants and agrees to and with the Mortgagee for the benefit of the
Lenders, which covenants, warranties and agreements, to the extent permitted by
law, shall be deemed to run with the land, as follows:

1.     The Mortgagor will pay to the Lenders all Several Obligations, subject to
       the terms of the Intercreditor Agreement, according to the terms of the
       relevant instruments or agreements evidencing it, and the Mortgagor
       agrees that this Mortgage is a continuing mortgage securing the payment
       of the Several Obligations; provided, however, upon final and irrevocable
       payment in full of the Several Obligations and termination of any
       commitment on the part of the Lenders to extend credit accommodations to
       or on behalf of Mortgagor, Mortgagee agrees to execute and deliver to
       Mortgagor a release of this Mortgage in recordable form.

2.     The Mortgagor has good and indefeasible title to the entire mortgaged
       premises in fee simple and with good right and full power to sell,
       mortgage and convey it; the mortgaged premises are free and clear of all
       easements, restrictions, liens, leases and encumbrances whether now
       existing or later created, except for Permitted Encumbrances and those
       matters listed on attached Exhibit B (if any) to which this Mortgage is
       expressly subject, and the Mortgagor will warrant and defend the
       mortgaged premises against all other claims and demands whatsoever.
       Subject to the terms of the Intercreditor Agreement, the Mortgagee shall
       have the right, at such time or times as it, in its reasonable
       discretion, deems necessary, to take whatever action it may deem
       necessary to defend or uphold the lien of this Mortgage or otherwise
       enforce any of the rights of the Mortgagee and the Lenders under this
       Mortgage or any obligation secured by this Mortgage including, without
       limit, the right to institute appropriate legal proceedings for these
       purposes.

3.     Except as otherwise provided in the Agreements or the Intercreditor
       Agreement, the Mortgagor shall pay prior to becoming delinquent and
       before any interest, collection fees or penalties accrue or default
       occurs, all taxes, assessments, encumbrances, liens, mortgages, water or
       sewer 

                                       6
<PAGE>
 
       charges and other charges and impositions levied, assessed or existing
       with respect to the mortgaged premises or any part of it, and will
       deliver to the Mortgagee without demand official receipts showing these
       payments. Subject to Mortgagor's right to contest payment of these
       amounts in accordance with the terms of the Agreements and the
       Intercreditor Agreement, if the Mortgagor fails to pay these taxes,
       assessments, encumbrances, liens, mortgages, charges and impositions when
       due, or if the Mortgagor fails to pay all interest, collection fees and
       penalties accrued on them, the Mortgagee, at its sole option, may,
       subject to the terms of the Intercreditor Agreement, (but is not
       obligated to) pay them and the monies paid shall be a lien upon the
       mortgaged premises added to the amount secured by this Mortgage and
       payable immediately by the Mortgagor to the Mortgagee, with interest at
       the higher of (i) the interest rate, if any, charged by the particular
       entity levying or assessing the tax, assessment or imposition or holding
       the encumbrance or lien, or (ii) the highest rate charged by the Lenders
       on any of the Several Obligations (but in either case not to exceed the
       maximum interest rate permitted by applicable law).

       At the request of the Mortgagee, subject to the terms of the
       Intercreditor Agreement, made any time following the occurrence of an
       event of default under this Mortgage, the Mortgagor shall pay to the
       Mortgagee in advance on the first day of each month a pro rata portion
       (as reasonably determined by the Mortgagee) of all taxes, assessments,
       liens, encumbrances, mortgages, and other charges levied, assessed or
       existing on the mortgaged premises. In the event that sufficient funds
       have been deposited with the Mortgagee to cover the amount of these
       taxes, assessments, liens, encumbrances, mortgages, and other charges
       when they become due and payable, the Mortgagee shall pay the same when
       due and payable. In the event that sufficient funds have not been
       deposited to cover the amount of these taxes, assessments, liens,
       encumbrances, mortgages and other charges at least thirty (30) days prior
       to the time when they become due and payable, the Mortgagor shall
       immediately upon request by the Mortgagee pay the amount of the
       deficiency to the Mortgagee. The Mortgagee shall not be required to keep
       any such deposits in a separate account or to pay the Mortgagor any
       interest or earnings whatever on the funds held by the Mortgagee for the
       payment of taxes, assessments, liens, encumbrances, mortgages, or other
       charges pursuant to this paragraph or for the payment of insurance
       premiums under paragraph (4) below, or on any

                                       7
<PAGE>
 
       other funds deposited with the Mortgagee in connection with this
       Mortgage. If an event of default occurs under this Mortgage, any funds
       then remaining on deposit with the Mortgagee may be applied in a manner
       consistent with the terms of the Intercreditor Agreement, against the
       Several Obligations immediately upon or at any time after the event of
       default occurs, and without notice to the Mortgagor. Further, the
       Mortgagee may, subject to the terms of the Intercreditor Agreement, make
       payments from any funds on deposit with the Mortgagee for taxes,
       assessments, liens, encumbrances, mortgages, or other charges on or with
       respect to the mortgaged premises notwithstanding that subsequent owners
       of the premises may benefit as a result. The Mortgagor shall not, and
       nothing in this Mortgage shall be construed to give the Mortgagor the
       right to, mortgage or pledge the mortgaged premises or any part of it as
       security for any other indebtedness or obligations. Nothing in this
       paragraph shall be considered a consent by the Mortgagee or the Lenders
       to any lien, mortgage or encumbrance on the mortgaged premises except the
       Permitted Encumbrances and those matters set forth on attached Exhibit B,
       if any.

4.     The Mortgagor shall keep the buildings and all other improvements now or
       later existing on the mortgaged premises constantly insured for the
       benefit of the Mortgagee and the Lenders against fire and other hazards
       and risks, including without limit vandalism and malicious mischief, as
       the Mortgagee may reasonably require and shall further provide flood
       insurance (if the mortgaged premises are situated in an area which is
       considered a flood risk area by the United States Department of Housing
       and Urban Development, and in which flood insurance has been made
       available under the National Flood Insurance Act of 1968, as amended),
       loss of rents insurance, public liability and product liability insurance
       and any other insurance as the Mortgagee may reasonably require from time
       to time, all in amounts and in forms and with companies as are reasonably
       satisfactory to the Mortgagee and the Lenders. The Mortgagor shall
       deliver to the Mortgagee the policies evidencing the required insurance
       with premiums fully paid for one year in advance and with standard
       mortgagee clauses (making all loss payable to the Mortgagee on behalf of
       the Lenders) satisfactory to the Mortgagee and the Lenders. Renewals of
       the required insurance (together with evidence of premium prepayment for
       one year in advance) shall be delivered to the Mortgagee at least thirty
       (30) days before the expiration of any existing policies. All policies
       and renewals shall provide that they may not be canceled or amended
       without giving the Mortgagee

                                       8
<PAGE>
 
       thirty (30) days prior written notice of cancellation or amendment. All
       policies and renewals shall be held by, and are pledged to, the Mortgagee
       for the equal and ratable benefit of the Lenders, along with all
       insurance premium rebates, as additional security for the Several
       Obligations. Should the Mortgagor fail to insure or fail to pay the
       premiums on any required insurance or fail to deliver the policies or
       renewals of them as provided above, the Mortgagee may (but is not
       obligated to) have the insurance issued or renewed (and pay the premiums
       on it for the account of the Mortgagor) in amounts and with companies and
       at premiums as the Mortgagee and the Lenders reasonably deem appropriate.
       If the Mortgagee elects to have insurance issued or renewed to insure the
       Mortgagee's interest, the Mortgagee shall have no duty or obligation of
       any kind to also insure the Mortgagor's interest. Any premiums or other
       sums paid by the Mortgagee for insurance as provided above shall be a
       lien upon the mortgaged premises added to the amount secured by this
       Mortgage and payable immediately, with interest on those sums at the
       highest rate charged by the Lenders on any of the Several Obligations
       (but not to exceed the maximum interest rate permitted by applicable
       law). In the event of loss or damage, the proceeds of all required
       insurance shall be paid to the Mortgagee for the equal and ratable
       benefit of the Lenders, alone. No loss or damage shall itself reduce the
       Several Obligations. The Mortgagee and any of its employees is each
       irrevocably appointed attorney-in-fact for the Mortgagor and is
       authorized to adjust and compromise each loss without the consent of the
       Mortgagor, to collect, receive and receipt for the insurance proceeds in
       the name of the Mortgagee and the Mortgagor and to endorse the
       Mortgagor's name upon any check in payment of the loss. The proceeds
       shall be applied first toward reimbursement of all costs and expenses of
       the Mortgagee in collecting the proceeds (including, without limit, court
       costs and reasonable attorneys' fees), and then, subject to the terms of
       the Intercreditor Agreement, toward payment of the Several Obligations or
       any portion of it, whether or not then due or payable, or the Mortgagee,
       at its option, with the consent of the Lenders pursuant to the terms of
       the Intercreditor Agreement, may apply the insurance proceeds, or any
       part of them, to the repair or rebuilding of the mortgaged premises. In
       the event of a foreclosure of this Mortgage, or the giving of a deed in
       lieu of foreclosure, the purchaser or grantee of the mortgaged premises
       shall succeed to all of the rights of the Mortgagor under said insurance
       policies including, without limit, any right to unearned premiums and to
       receive the

                                       9
<PAGE>
 
       proceeds. At the request of the Mortgagee made any time following the
       occurrence of an event of default under this Mortgage, the Mortgagor
       shall pay to the Mortgagee in advance on the first day of each month the
       equivalent of one-twelfth (1/12th) of the annual premiums (as reasonably
       estimated by the Mortgagee) due on the required insurance, but with an
       initial payment which together with subsequent monthly payments will be
       sufficient to pay the estimated annual premiums as provided in this
       paragraph. In the event that sufficient funds have been deposited with
       the Mortgagee to cover the amount of the insurance premiums for required
       insurance when the premiums become due and payable, the Mortgagee shall
       pay the premiums when the same are due and payable. In the event that
       sufficient funds have not been deposited with the Mortgagee to pay the
       insurance premiums at least thirty (30) days prior to the time when they
       become due and payable, the Mortgagor shall immediately upon request pay
       the amount of this deficiency to the Mortgagee.

5.     [Reserved]

6.     The Mortgagor shall abstain from commission of waste upon the mortgaged
       premises, keep the buildings, improvements and equipment on the mortgaged
       premises in good repair, ordinary wear and tear, damage by fire or other
       casualty and takings by eminent domain excepted and promptly comply in
       all material respects with all laws, regulations and requirements of all
       governmental bodies affecting the mortgaged premises the enforcement of
       which, if Mortgagor were not in compliance, would reasonably be expected
       to materially adversely affect the value or use of the mortgaged
       premises. If the Mortgagee determines that the mortgaged premises, or any
       part of it, requires inspection, testing, appraisal, repair, care,
       alteration or attention of any kind or nature, not provided to the
       Mortgagee's satisfaction by the Mortgagor, the Mortgagee after such
       notice to Mortgagor as is reasonable under the circumstances as
       determined in good faith by the Mortgagee, may (but is not obligated to)
       enter or cause entry to be made upon the mortgaged premises, and inspect,
       test, appraise, repair, alter or maintain the mortgaged premises as the
       Mortgagee may deem necessary, and the Mortgagor shall reimburse the
       Mortgagee upon demand for all resulting costs and expenses incurred by
       the Mortgagee. Following the occurrence and during the continuance of an
       event of default hereunder, the Mortgagee may pay sums of money as the
       Mortgagee deems essential for the preservation of the mortgaged premises,
       and these sums shall be additional Several Obligations

                                       10
<PAGE>
 
       secured by this Mortgage, shall be payable by the Mortgagor to the
       Mortgagee for the equal and ratable benefit of the Lenders upon demand,
       and shall bear interest at the highest rate charged by the Lenders to the
       Mortgagor on any of the Several Obligations (but not to exceed the
       maximum interest rate under applicable law). The failure of Mortgagor to
       pay any taxes or assessments assessed against the mortgaged premises, or
       any installment of them, or any premiums payable with respect to any
       insurance policy covering the mortgaged premises, shall constitute waste
       (although the meaning of "waste" shall not be limited to this
       nonpayment). The Mortgagor consents to the appointment of a receiver
       should the Mortgagee seek this relief. The Mortgagor shall not make or
       permit any other party to make any alterations, additions or improvements
       of any type to the mortgaged premises the cost of which, individually or
       in the aggregate exceeds $500,000 (individually and collectively the
       "Improvements"), regardless of whether the Improvements would increase
       the value of the mortgaged premises, without the Mortgagee's and the
       Lenders' prior written consent, which consent shall not unreasonably be
       withheld, conditioned or delayed. If the Mortgagee and the Lenders
       consent to the making of any Improvements on the mortgaged premises, and
       the Improvements are not completed with due diligence in accordance with
       the plans and specifications approved in writing by the Mortgagee and the
       Lenders, or if construction of the Improvements should cease before
       completion for a period of thirty (30) days, then and in either event it
       shall be an event of default under this Mortgage and the Mortgagee shall
       have all the rights and remedies provided in this Mortgage upon an event
       of default, and all the rights and remedies set forth in this paragraph
       6, including without limitation, the right (but not the obligation) to
       enter or cause entry to be made upon the mortgaged premises and complete
       the Improvements, with full power and authority to enter into such
       contracts or agreements as the Mortgagee may deem necessary to complete
       the Improvements.

7.     Subject to Mortgagor's right to contest payment of these amounts in
       accordance with the terms of the Credit Agreement and the Note
       Agreements, and subject to the terms of the Intercreditor Agreement, the
       Mortgagor shall pay (before the same become liens, encumbrances or
       charges against the mortgaged premises) any and all obligations,
       liabilities or debts for repairs or improvements to the mortgaged
       premises or for any other goods, services, or utilities furnished to the
       mortgaged premises. The Mortgagor shall not mortgage or 

                                       11
<PAGE>
 
       pledge the mortgaged premises or any part of it as security for any other
       indebtedness or obligations.

8.     In the event the mortgaged premises, or any part of it, is taken under
       power of eminent domain, or by condemnation, the entire proceeds of the
       award shall be paid directly to the Mortgagee for the equal and ratable
       benefit of the Lenders and applied first toward reimbursement of all the
       Mortgagee's costs and expenses incurred in connection with collecting the
       award (including, without limit, court costs and reasonable attorneys'
       fees), and the second, balance applied upon the Several Obligations
       whether or not then due or payable as set forth in the Intercreditor
       Agreement. During the continuance of an event of default hereunder or if
       Mortgagor fails to take such action as the Mortgagee reasonably may
       require with respect thereto, the Mortgagee or any of its employees is
       irrevocably appointed attorney-in-fact and is duly authorized and
       empowered to receive, receipt for, discharge and satisfy any condemnation
       award and judgment, whether joint or several, on behalf of the Mortgagor,
       his legal representatives and assigns. This receipt, discharge and
       satisfaction shall be as legally effective and binding as if given
       directly by the Mortgagor; provided, however, that neither the Mortgagee
       nor any Lender shall be liable for failure to collect any condemnation
       award, regardless of the cause of such failure.

9.     The Several Obligations secured by this Mortgage shall become due and
       payable immediately, without notice, at the option of the Mortgagee and
       the Lenders, if the Mortgagor shall convey, assign or transfer the
       mortgaged premises or any part of it by deed, land contract or other
       instrument without the consent of Mortgagee and the Lenders, which
       consent may be withheld in the sole discretion of Mortgagee and the
       Lenders, or if title to the mortgaged premises or any part of it shall
       become vested in any other person or party in any manner whatsoever
       without the consent of Mortgagee and the Lenders, which consent may be
       withheld in the sole discretion of the Mortgagee and the Lenders. In the
       event ownership of the mortgaged premises or any part of it becomes
       vested in a person or persons other than the Mortgagor (without the prior
       written approval of the Mortgagee and the [Lenders] as aforesaid), the
       Mortgagee may (but shall not be obligated to) deal with and may enter
       into any contract or agreement with the successor or successors in
       interest with reference to this Mortgage in the same manner as with the
       Mortgagor, without in any manner vitiating, discharging or otherwise
       affecting the lien of

                                       12
<PAGE>
 
       this Mortgage or the Mortgagor's liability under this Mortgage or upon
       the Several Obligations.

10.    This Mortgage shall, as to any equipment, fixtures and other personal
       property constituting fixtures under applicable law, be deemed to grant a
       security interest in the equipment, fixtures, accounts, general
       intangibles and other personal property pursuant to the Uniform
       Commercial Code. The Mortgagor agrees, upon request of the Mortgagee from
       time to time, to promptly furnish a list of personal property owned by
       the Mortgagor and subject to this Mortgage and, upon request by the
       Mortgagee, to immediately execute, deliver and/or file any mortgage and
       any amendments to this Mortgage, any separate security agreement and any
       financing statements to include specifically this list of personal
       property. Upon the occurrence of any event of default under this
       Mortgage, the Mortgagee shall have all of the rights and remedies of a
       secured party under the Uniform Commercial Code or otherwise provided by
       law or by this Mortgage including, without limit, the right to require
       the Mortgagor to assemble the personal property and make it available to
       the Mortgagee at a place to be designated by the Mortgagee which is
       reasonably convenient to both parties, the right to take possession of
       the personal property with or without demand and with or without process
       of law and the right to sell and dispose of it and distribute the
       proceeds according to law. The Mortgagor agrees that any requirement of
       reasonable notice shall be met if the Mortgagee sends notice to the
       Mortgagor at least five (5) days prior to the date of sale, disposition
       or other event giving rise to the required notice. The Mortgagor agrees
       that the proceeds of any disposition of the personal property may be
       applied by the Mortgagee first to the Mortgagee's reasonable expenses in
       connection with the disposition including, without limit, reasonable
       attorneys' fees and legal expenses, and then to payment of the Several
       Obligations as set forth in the Intercreditor Agreement.

11.    As additional security for the payment of the Several Obligations and
       performance of this Mortgage, the Mortgagor assigns to the Mortgagee for
       the equal and ratable benefit of the Lenders all its right, title and
       interest in and to all written and oral leases and occupancy agreements,
       now or later existing, covering the mortgaged premises or any part of it
       (but without an assumption by the Mortgagee or the Lenders of liabilities
       of the Mortgagor under any of these leases or occupancy agreements by
       virtue of this assignment), and the Mortgagor assigns to the Mortgagee
       for

                                       13
<PAGE>
 
       the equal and ratable benefit of the Lenders, the rents, issues and
       profits of the mortgaged premises. Prior to the occurrence of an event of
       default under this Mortgage, Mortgagor shall have a license to collect
       all rents arising from the mortgaged premises. If an event of default
       occurs under this Mortgage, the Mortgagee may receive and collect the
       rents, issues and profits personally or through a receiver so long as the
       event of default exists and during the pendency of any foreclosure
       proceedings and during any redemption period. The Mortgagor agrees to
       consent to the appointment of a receiver if this is believed necessary or
       desirable by the Mortgagee to enforce its rights under this Mortgage. The
       Mortgagee shall at no time have any obligation whatever to attempt to
       collect rent or other amounts from any tenant or occupier of the
       mortgaged premises notwithstanding that such tenants and occupiers may
       not be paying rent or other amounts to either the Mortgagor or to the
       Mortgagee. Further, the Mortgagee shall at no time have any obligation
       whatever to enforce any other obligations owed by tenants or occupiers of
       the mortgaged premises to the Mortgagor. No action taken by the Mortgagee
       or any Lender under this Mortgage shall make the Mortgagee or any Lender
       a "mortgagee in possession." The Mortgagor shall at no time collect
       advance rent more than thirty (30) days in advance under any lease or
       occupancy agreement pertaining to the mortgaged premises or any part of
       it in excess of one month (other than as a security deposit) and the
       Mortgagee shall not be bound in any respect by any rent prepayment made
       or received in violation of this prohibition. As additional security for
       the Several Obligations, the Mortgagor assigns to the Mortgagee for the
       benefit of the Lenders all of the Mortgagor's rights and interest, if
       any, in all licenses and permits affecting the mortgaged premises. This
       assignment shall not be construed as a consent by the Mortgagee to any
       license or permit so assigned, or to impose upon Mortgagee any
       obligations with respect to any license or permit. The Mortgagor shall
       not cancel or amend any of the licenses and permits assigned (nor permit
       any of them to terminate if they are necessary or desirable for the
       operation of the mortgaged premises) without first obtaining the written
       approval of the Mortgagee and the Lenders, which approval shall not
       unreasonably be withheld, conditioned or delayed. This paragraph shall
       not be applicable to any license or permit that terminates if it is
       assigned without the consent of another party (other than the Mortgagor)
       or its issuer, unless this consent has been obtained or this assignment
       is ratified by the other party or issuer; nor shall this

                                       14
<PAGE>
 
       paragraph be construed as a present assignment of any license or permit
       that the Mortgagor is required by law to hold in order to operate the
       mortgaged premises.

12.    As additional security for the Several Obligations, the Mortgagor grants 
       a security interest to the Mortgagee and the Lenders in all deposit or
       other accounts with the Mortgagee and the Lenders.

13.    In the event any tax shall be due with respect to the execution and
       delivery or recordation of this Mortgage or any note or other instrument
       evidencing or securing repayment of the Several Obligations or the
       interest of the Mortgagee in the mortgaged premises, whether levied
       against the Mortgagee or otherwise, the Mortgagor shall pay this tax at
       the time and in the manner required by applicable law. The Mortgagor
       shall hold the Mortgagee and the Lenders harmless and shall indemnify the
       Mortgagee and the Lenders against all liability of any nature whatever as
       a result of the imposition of this tax. In the event payment by the
       Mortgagor of this tax would result in the payment of interest in excess
       of the permitted rate, then the Mortgagor shall have no obligation to pay
       the portion of the tax resulting in this excess; provided, however, that
       in this event the Lenders may declare the entire principal balance of the
       Several Obligations, premium, if any, and accrued interest on it,
       immediately due and payable.

14.   (a)   In the event this Mortgage is foreclosed or the Mortgagor tenders a
            deed in lieu of foreclosure, the Mortgagor shall deliver the
            mortgaged premises to the Mortgagee, purchaser or grantee, as the
            case may be, in material compliance with all Environmental Laws.

      (b)   Upon the Mortgagee's receipt of any notice from any source asserting
            the release of any Hazardous Materials or an Environmental Complaint
            pertaining to the mortgaged premises which, if true, could
            reasonably be expected to result in an order, suit or other action
            against the Mortgagor and/or any part of the mortgaged premises
            which could reasonably be expected to materially jeopardize
            Mortgagee's and the Lenders' security under this Mortgage and upon
            ten (10) days notice to the Mortgagor (except in an emergency or
            where not practical under applicable law, in which case notice is
            waived), and without limitation of the Mortgagee's other rights
            under this Mortgage or elsewhere, the Mortgagee has the right, 

                                       15
<PAGE>
 
            but not the obligation, to enter on the mortgaged premises and to
            take other actions as it deems appropriate to investigate or test
            for, clean up, remove, resolve, minimize the impact of or, as
            required by law, advise governmental agencies of the possible
            release of any Hazardous Materials or a notice of any violation of
            Environmental Laws ("Environmental Complaint"). All reasonable costs
            and expenses incurred by the Mortgagee in the exercise of any of
            these rights shall be secured by this Mortgage and shall be payable
            by the Mortgagor upon demand. Any such actions conducted by the
            Mortgagee shall be solely for the benefit of and to protect the
            interests of the Mortgagee and the Lenders and shall not be relied
            upon by the Mortgagor or any third party for any purpose whatsoever.
            By conducting any such actions, the Mortgagee does not assume
            control over the environmental affairs or operations of the
            Mortgagor nor assume any liability of the Mortgagor or any third
            party.

      (c)   The provisions of this paragraph (14) shall be in addition to any
            and all other obligations and liabilities the Mortgagor may have to
            the Mortgagee and the Lenders at common law or pursuant to any other
            agreement. The indemnification obligations contained in part (b) of
            this paragraph (14) shall survive (i) the repayment of all sums due
            under any note or other loan documents executed in connection with
            this Mortgage and the repayment of all other Several Obligations,
            (ii) the satisfaction of all other obligations of the Mortgagor
            under this Mortgage and under the other loan documents and
            evidence(s) of indebtedness, (iii) the discharge of this Mortgage,
            and (iv) the foreclosure of this Mortgage or acceptance of a deed in
            lieu of foreclosure.

      (d)   For purposes of this Mortgage, (i) "Hazardous Materials" means each
            and all of the following: hazardous materials and/or substances as
            defined in any Environmental Law, petroleum, petroleum by-products,
            natural gas, flammable explosives, radioactive materials, and toxic
            materials, and (ii) "Environmental Laws" mean any and all federal,
            state, local or other laws (whether under common law or by
            legislative action), rules, ordinances, court or agency, orders,
            statutes, or regulations an object of which is to regulate or
            improve health, safety, or the 

                                       16
<PAGE>
 
            environment including, without limit, the Comprehensive
            Environmental Response, Compensation and Liability Act of 1980, as
            amended (42 USC 9601 et seq.), the Resource Conservation and
            Recovery Act, as amended (42 USC 6901 et seq.).

15.    The Mortgagor shall comply with and perform in the time required all
       obligations and restrictions imposed upon the Mortgagor or the mortgaged
       premises under applicable deed restrictions, restrictive covenants,
       easements or other agreements affecting the mortgaged premises the
       enforcement of which, if Mortgagor were not in compliance, would
       reasonably be expected to materially adversely affect the
       value or use of the mortgaged premises, but this is not a consent by the
       Mortgagee to take subject to any of these agreements unless specifically
       set forth on attached Exhibit B, if any, and the Mortgagee does not
       assume any obligations under these agreements.

16.    If the Mortgagor fails to perform in the time and manner (subject to any

       under the circumstances as determined in good faith by the Mortgagee, at

       its remedies under this Mortgage or as otherwise provided by law:

      (a)   Default by the Mortgagor in making payment when due, by acceleration
            or otherwise, of any principal portion of or interest on the Several

       or the Several Obligations, all of these sums shall on demand be paid by
       the Mortgagor to the Mortgagee, together with the interest on these sums
       at the highest rate charged by the Lenders on any of the Several

21.    In the event of any foreclosure or other sale under this Mortgage by
       virtue of judicial proceedings, advertisement, or otherwise, the
       mortgaged premises may be sold in one parcel and as an entirety, or in
       such parcels, manner or order as the Mortgagee may subject to the terms
       of the Intercreditor Agreement, elect.

22.    Without limiting when a prepayment premium may be due, it is agreed that
       at any time after acceleration a tender of payment of the amount
       necessary to satisfy all Several Obligations by the Mortgagor, or by
       anyone on behalf of the Mortgagor or otherwise, must include any
       applicable prepayment premium or formula.

23.    Immediately upon the occurrence of any Event of Default (as defined in
       the Agreements) and during the continuance thereof, the Mortgagee shall
       have the option, in addition to and not in substitution for all other
       rights and remedies provided in this Mortgage or other agreement or by
       law, and is authorized by the Mortgagor, subject to the terms of the
       Intercreditor Agreement, to do any or all of the following:

       (a)  Declare the entire unpaid amount of the Several Obligations,
            together with accrued and unpaid interest on it and any applicable
            prepayment premium or formula, and any and all other charges payable
            by the Mortgagor to the Mortgagee or the Lenders to be immediately
            due and payable and, at the Mortgagee's option (i) to bring suit for
            the same, (ii) to bring suit for any delinquent payment of or upon
            the Several Obligations, or (iii) to take any and all steps and
            institute any and all other proceedings that the Mortgagee deems
            necessary to enforce payment of the Several Obligations and
            performance of other obligations secured under this Mortgage and to
            protect the lien of this Mortgage.

       (b)  Commence foreclosure proceedings against the mortgaged premises
            through judicial proceedings or by advertisement, at the option of
            the Mortgagee, pursuant to applicable law. The commencement by the
            Mortgagee of foreclosure proceedings shall be deemed an exercise by
            the Mortgagee of its option to accelerate the Several Obligations,
            unless such proceedings on their face specifically indicate
            otherwise. The Mortgagor grants power to the Mortgagee to sell the
            mortgaged premises or to cause the same to be sold at public sale,
            and to convey the same to the 

                                       19

            purchaser, in accordance with
            applicable statutes in a single parcel or in several parcels at the
            option of the Mortgagee.

            of the Mortgagee are specifically enforceable, the Mortgagor agrees
            that the Mortgagee's rights under this paragraph (23)(e) are
            specifically enforceable since there is no adequate monetary remedy
            available to the Mortgagee.

       (f)  Contest the amount or validity of any taxes applicable to the
            mortgaged premises by appropriate proceedings either in the
            Mortgagee's name, the Mortgagor's name or jointly with the
            Mortgagor. The Mortgagor shall execute and deliver to the Mortgagee,
            upon demand, whatever documents and information the Mortgagee
            determines may be necessary or proper to so contest the taxes or to
            secure payment of any resulting refund. The Mortgagor shall
            reimburse the Mortgagee for all reasonable costs and expenses,
            including without limit reasonable attorneys' fees, incurred in

                                       20
<PAGE>
 
            connection with each tax contest proceeding. All refunds resulting
            from each tax contest proceeding shall belong to the Mortgagee to be
            applied against the Several Obligations in the manner provided in
            the Intercreditor Agreement with the surplus, if any, to be paid to
            the Mortgagor. The Mortgagee and any of its employees is each
            irrevocably appointed attorney- in-fact for the Mortgagor and is
            authorized to execute and deliver in the name of the Mortgagor those
            documents deemed necessary or proper by the Mortgagee to carry out
            any tax contest proceeding or receive the resulting refunds, if any.

       (g)  In the event of any sale of the mortgaged premises by foreclosure,
            through judicial proceedings, by advertisement or otherwise, apply
            the proceeds of any such sale in the manner provided in the
            Intercreditor Agreement.

24.    If any provision of this Mortgage is in conflict with any statute or rule
       of law or is otherwise unenforceable for any reason, then that provision
       shall be deemed null and void to the extent of the conflict or
       unenforceability and shall be deemed severable, but shall not invalidate
       any other provision of this Mortgage.

25.    In the event of foreclosure of this Mortgage or the enforcement by the
       Mortgagee of any other rights and remedies under this Mortgage, the
       Mortgagor waives any right otherwise available in respect to marshalling
       of assets which secure the Several Obligations or to require the
       Mortgagee to pursue its remedies against any other assets or any other
       party which may be liable for any of the Several Obligations.

26.    Promptly upon the reasonable request of the Mortgagee, the Mortgagor
       shall execute, acknowledge and deliver any and all further conveyances,
       documents, mortgages and assurances, and do or cause to be done all
       further acts as the Mortgagee may reasonably require in its sole
       discretion to confirm and protect the lien of this Mortgage or otherwise
       to accomplish the purposes of this Mortgage.

27.    If more than one person or party has executed this Mortgage as the
       mortgagor, the term "Mortgagor" shall include each of the mortgagors
       individually and collectively, and all warranties, covenants, rights and
       powers given to or

       conferred upon the Mortgagee are made or given jointly and severally.

28.    Nothing contained in this Mortgage is intended, nor should it be
       construed, to preclude the Mortgagee or any Lender from pursuing any
       other remedy provided by law for the collection of the Several
       Obligations or any portion of it, or for the recovery of any other sum to
       which the Mortgagee or any Lender may be or become entitled for breach of
       this Mortgage by the Mortgagor, nor shall anything contained in this
       Mortgage reduce or release in any manner any rights, security interests
       or liens in favor of the Mortgagee for the benefit of the Lenders
       contained in any existing or future agreement between the Mortgagor and
       the Mortgagee.

29.    Any reference in this Mortgage to attorneys' fees shall be deemed a
       reference to the reasonable fees, charges, costs and expenses of both in-
       house and outside counsel and paralegals, whether or not a suit or
       proceeding is instituted, and whether incurred at the trial court level,
       on appeal, in a bankruptcy, administrative or probate proceeding, in a
       workout, in consultation with counsel, or otherwise. All reasonable
       costs, expenses and fees of any nature for which the Mortgagor is
       obligated to reimburse or indemnify the Mortgagee and the Lenders are
       part of the Several Obligations secured by this Mortgage and are payable
       upon demand, unless expressly provided otherwise, with interest until
       repaid at the highest rate charged by the Lenders on any of the Several
       Obligations (but not to exceed the maximum rate permitted by applicable
       law).

       entity which is superior to the lien of this Mortgage (other than
       Permitted Encumbrances), the Mortgagee has the right, (upon fifteen (15)
       days prior notice to the Mortgagor), but not the obligation, to acquire
       and/or pay off the holder of such right, title, interest or lien and add
       the amount so paid to the Several Obligations and charge interest on that
       amount at the highest rate charged by the Lenders to the Mortgagor on any
       of the Several Obligations (but not to exceed the maximum interest rate
       permitted under applicable law).

31.    Subject to the provisions of paragraph 41, this Mortgage constitutes the
       entire agreement of the Mortgagor and the Mortgagee with respect to the
       subject matter of this Mortgage. No waiver, consent, modification or
       change of the terms of this Mortgage shall bind the Mortgagor or the

                                       22
<PAGE>
 
       Mortgagee unless in writing and signed by the party, or an authorized
       officer of the party, against whom enforcement is sought. Each waiver,
       consent, modification or change shall be effective only for the specific
       purpose given.

32.    This Mortgage shall be binding on the Mortgagor and the Mortgagee and on
       the Mortgagor's and the Mortgagee's heirs, legal representatives,
       successors and assigns including, without limit, any debtor in possession
       or trustee in bankruptcy for the Mortgagor. This shall not be deemed a
       consent by the Mortgagee to a conveyance by the Mortgagor of all or part
       of the mortgaged premises or of any ownership interest in the Mortgagor.

33.    The Mortgagor has entered into this Mortgage in good faith for the
       purpose of inducing the Mortgagee to extend credit or make other
       financial accommodations to or at the request of the Mortgagor.

       by Mortgagor to any third party, the Mortgagor shall promptly provide the
       Mortgagee with certificates of occupancy, licenses, rent rolls, income
       and expense statements and other documents and information pertaining to
       the mortgaged premises and its operations as the Mortgagee, from time to
       time, may request.

35.    At the sole option of the Mortgagee, this Mortgage shall become
       subordinate, in whole or in part (but not with respect to priority as to

       party designated by the Mortgagor with information concerning or results
       of any inspection, audit, appraisal or examination by the Mortgagee or
       its agents. If the Mortgagee or a Lender, in its sole discretion,
       discloses information to the Mortgagor this disclosure is for the sole
       protection of the Mortgagee or the Lenders, does not constitute an
       agreement to further disclosure and does not create a warranty by the
       Mortgagee or the Lenders as to the accuracy, sufficiency or any other
       aspect of the disclosure.

38.    Upon full and final payment of the Several Obligations in cash and
       performance by the Mortgagor of all its other obligations under this
       Mortgage, except as otherwise provided in paragraph 14 of this Mortgage,
       the parties shall automatically each fully, finally and forever release

       IN WHICH A JURY TRIAL HAS BEEN WAIVED WITH ANY OTHER ACTION IN WHICH A
       JURY TRIAL CANNOT BE OR HAS NOT BEEN WAIVED. THESE PROVISIONS SHALL NOT
       BE DEEMED TO HAVE BEEN MODIFIED IN ANY RESPECT OR RELINQUISHED BY THE
       MORTGAGOR AND/OR MORTGAGEE EXCEPT BY A WRITTEN INSTRUMENT EXECUTED BY ALL
       OF THEM.

41.    Notwithstanding any provision in paragraph 4 or paragraph 8 hereof to the
       contrary, in the event any proceeds become 

                                       24
<PAGE>
 
       available as a result of the condemnation of all or any part of the
       mortgaged premises, or any insurance proceeds become available as a
       result of any hazard insurance loss, Mortgagee will make such proceeds
       available to Mortgagor for use in the repair and restoration of the
       mortgaged premises to the condition existing immediately prior to the
       condemnation or loss, or such other condition as Mortgagee may approve in

       (b)  Mortgagee shall approve in writing plans and specifications of an
            architect satisfactory to Mortgagee and contractor's cost estimates

       (c)  Such proceeds are deemed sufficient by Mortgagee to pay all costs
            of, and expenses incidental to, such repair or restoration and, if
            such proceeds shall be deemed insufficient to pay same, Mortgagor
            shall deposit with Mortgagee such additional sums as Mortgagee deems
            necessary, in its reasonable judgment, when combined with such
            proceeds, to pay such costs and expenses;

       (d)  Such proceeds shall be disbursed by advances conforming to the
            requirements for advances ordinarily set forth in construction loan
            agreements then in use by Mortgagee, and to such other requirements
            as Mortgagee may reasonably impose;

            costs reasonably incurred by Mortgagee in connection therewith; and

       have the meanings set forth in the Intercreditor Agreement.
       Notwithstanding anything herein to the contrary, in the event of any
       conflict between the terms and provisions of this Mortgage and the terms
       and provisions of the Agreements (and, as among the Lenders, but not
       otherwise, the Intercreditor Agreement) shall control.

                SECOND AMENDED AND RESTATED SECURITY AGREEMENT
                ----------------------------------------------
                              (Third Party Pledge)

     D.  Pursuant to the separate Note Agreements dated as of May 31, 1996 (as

     E.  Pursuant to and in accordance with the Credit Agreement  and the Note

under the Revolving Credit, the Swing Line, the Credit Agreement (including any
Letters of Credit issued thereunder), the Note Agreements, the Senior Notes, and
the other documents, instruments, certificates or agreements executed by
Borrower pursuant to or in connection with any such document or the Agreements,
as such documents may be amended or otherwise modified from time to time
(collectively herein, the "Loan Documents").

     F.  Company and Agent desire to amend and restate the Prior Security
Agreement to reflect the events set forth in the foregoing recitals.

     G.  Agent is acting as Collateral Agent for the Lenders pursuant to Section
___ of that certain Intercreditor and Collateral Agency Agreement dated as of
May 31, 1996 by and among Borrower, Agent as Collateral Agent and the Lenders
(as amended from time to time, the "Intercreditor Agreement").

     NOW, THEREFORE, for and in consideration of the mutual promises, covenants
and agreements hereinafter set forth, the parties hereto agree as follows:

     Company hereby assigns, transfers, delivers and pledges to the Collateral
Agent, for the equal and ratable benefit of the Lenders, the following
securities and stocks:

     1,723 shares of the capital stock of R.J. Tower Corporation, a Michigan
     corporation ("Borrower") and all other shares of Borrower now owned or
     hereafter acquired by Company.

     Company grants the Collateral Agent, for the equal and ratable benefit of
the Lenders, a security interest in all of the above property, and all property
substituted therefor or for any part thereof, all records (including computer
software) pertaining thereto and all interest, dividends, increase, profits, new

                                       2
<PAGE>
 
securities or other increments, distributions or rights of any kind received on
account of this property, products or proceeds thereof (whether cash or non-cash
proceeds) resulting from any sale or exchange or transfer thereof or arising by
virtue of ownership thereof (such as, but not limited to, the rights to
additional or other securities or property upon any corporate reorganization,
merger, consolidation, liquidation or dissolution, offering of stock rights,
stock split or stock or liquidating dividend or the rights to any goods
evidenced by such property or insurance proceeds with respect thereto), and all
subscription, voting and preferential rights, all said property, products and
proceeds herein called the "Collateral." The creation of a security interest in
proceeds is not to be construed to give Company any right to dispose of the
Collateral. Company warrants that Company has clear title to the Collateral,
free from any liens, claims or encumbrances except the security interest created
by this Security Agreement, and has full power and authority to execute and
perform this Security Agreement.

     The security interest created herein is given as security for:

     1.   All of Borrower's obligations contained in or arising under or in
connection with the Credit Agreement and the Notes issued by it from time to
time pursuant to the Credit Agreement, the Note Agreements and the Senior Notes
and all obligations of the Borrower and each of the Account Parties contained in
or arising under the other Loan Documents executed by it;

     2.   All obligations of Borrower under any and all Hedging Transactions (as
defined in the Credit Agreement) entered into by the Borrower pursuant to an
Interest Rate Protection Agreement (as defined in the Credit Agreement) entered
into between the Borrower and any Bank or any Affiliate of a Bank; and

     3.   The obligations of Company, Borrower or any Account Party for payment
of all sums hereafter loaned, paid out, expended or advanced by or for the
account of the Lenders (or any of them) or by the Collateral Agent under the
terms of this Security Agreement, the Credit Agreement, the Note Agreements, the
Senior Notes, or the other Loan Documents, in connection with the Collateral or
any of the documents or instruments described in this Security Agreement, the
Agreements or the other Loan Documents; together with interest thereon; and also
as security for all other indebtedness and liabilities, whether direct,
indirect, absolute or contingent, owing by the Borrower or any Account Party to
the Collateral Agent or the Lenders in any manner under the Credit Agreement,
the Note Agreements, the Senior Notes or the other Loan

                                       3
<PAGE>
 
Documents, which hereafter become due, or that may hereafter be incurred by 
the Borrower or any Account Party to or acquired (pursuant to the Credit
Agreement, the Note Agreements, the Senior Notes or the other Loan Documents) by
the Collateral Agent, the Agent or the Lenders, and all other future obligations
of the Company or any Account Party to the Collateral Agent, or the Lenders,
their successors and assigns, howsoever created, arising or evidenced, whether
joint or several, direct or indirect, absolute or contingent, primary or
secondary, and any judgments that may hereafter be rendered on such indebtedness
or any part thereof, with interest according to the rates and terms specified,
or as provided by law, and any and all replacements, consolidations, amendments,
renewals or extensions of the foregoing (collectively herein called the "Several
Obligations").

     All capitalized terms used but not defined herein shall have the meaning
set forth in the Intercreditor Agreement and if not defined therein, then as
defined in the Credit Agreement or the Note Agreements or the other Loan
Documents, as applicable.  Except as otherwise provided herein, all other terms
used in this Security Agreement shall have the meanings given under Article 9 of
the Michigan Uniform Commercial Code, or in any other article, if not defined in
Article 9. Michigan Uniform Commercial Code shall mean Act 174 of the Michigan
Public Acts of 1962, as amended from time to time.

     Company agrees to keep the Collateral free at all times from any and all
claims, liens, security interests, and encumbrances other than those in favor of
Collateral Agent, for the equal and ratable benefit of the Lenders.

     Company will execute such endorsements or assignments of the Collateral as
Collateral Agent may reasonably request.

     Collateral Agent agrees to use reasonable care in the custody and
preservation of Collateral in its possession but assumes no duty to take steps
necessary to preserve rights against prior parties.

     So long as no Default (as defined below) shall have occurred and be
continuing, Company shall be entitled to receive and collect by legal
proceedings or otherwise all dividends, interest, principal payments and other
sums and all other distributions at any time payable or receivable on account of
the Collateral.

     At any time following the occurrence and during the continuance of Default
(as defined below) and without notice, Collateral Agent may, subject to the
terms of the Intercreditor 

                                       4
<PAGE>
 
Agreement (a) cause the Collateral or any portion of it to be transferred to its
name or to the name of its nominee or nominees; (b) receive or collect by legal
proceedings or otherwise all dividends, interest, principal payments and other
sums and all other distributions at any time payable or receivable on account of
the Collateral, and hold the same as Collateral, or apply the same to the
Several Obligations, the manner and distribution of the application to be in
accordance with the terms of the Intercreditor Agreement; (c) enter into any
extension, subordination, reorganization, deposit, merger or consolidation
agreement or any other agreement relating to or affecting the Collateral, and
deposit or surrender control of the Collateral, and accept other property in
exchange for the Collateral and apply the property or money so received in
accordance with the provisions of the Intercreditor Agreement.

     There shall be a default ("Default") under this Security Agreement if there
shall occur an Event of Default, as such term is defined in either the Credit
Agreement or the Note Agreements. Following the occurrence and during the
continuation of a Default, the Collateral Agent may, subject to the terms of the
Intercreditor Agreement, to the extent permitted by applicable law, enforce its
security interest in the Collateral by retaining the Collateral in satisfaction
of the Several Obligations, by public or private sale of all or any part of the
Collateral or by exercising any other remedy provided by law or applicable
agreement. The parties agree that five days written notice sent by ordinary mail
to Company at the address designated below shall be deemed reasonable notice of
any disposition of the Collateral, should notice be required by law.

     Subject to the terms of the Credit Agreement, the Note Agreements and the
Intercreditor Agreement, as the case may be, the Lenders may assign any of the
Several Obligations and Collateral Agent may assign its interest as Collateral
Agent and deliver all or any part of the Collateral to its assignee, who then
shall have with respect to the Collateral so delivered all the rights and powers
of the Collateral Agent under this Security Agreement and after that the
Collateral Agent shall be fully discharged from all liability and responsibility
with respect to the Collateral so delivered.

     If Collateral Agent redelivers Collateral to Company or Company's designee
for the purpose of

(a)  the ultimate sale or exchange thereof, or

                                       5
<PAGE>
 
(b)  presentation, collection, renewal, or registration of transfer thereof,

such redelivery shall be in trust for the benefit of Collateral Agent and the
Lenders and shall not constitute a release of Collateral Agent's security
interest therein or in the proceeds or products thereof unless Collateral Agent
specifically so agrees in writing. If Company requests any such redelivery,
Company will deliver with such request a duly executed financing statement in
form and substance satisfactory to Collateral Agent. Any proceeds of Collateral
coming into the Company's possession as a result of any such redelivery shall be
held in trust for Collateral Agent for the equal and ratable benefit of the
Lenders and forthwith delivered to Collateral Agent for application on the
Several Obligations in accordance with the terms of the Intercreditor Agreement.
Subject to the terms of the Intercreditor Agreement, Collateral Agent may
deliver the Collateral or any part of the Collateral to Company, and such
delivery by Collateral Agent shall discharge Collateral Agent from any and all
liability or responsibility for such Collateral.

     Company waives notice of acceptance of this Security Agreement and
presentment, demand, protest, notice of protest, dishonor, notice of dishonor,
notice of demand, notice of intent to demand, notice of acceleration, notice of
intent to accelerate, notice of default and diligence in collecting any Several
Obligations, and agrees that the Collateral Agent and the Lenders may modify the
terms of borrowing, compromise, extend, increase, accelerate, renew or forbear
to enforce payment of any part or all of any Several Obligations, or permit the
Borrower to incur additional Several Obligations, all without notice to Company
and without affecting in any manner the Collateral Agent's rights under this
Security Agreement. Company further waives any and all other notices to which
Company might otherwise be entitled. Company acknowledges and agrees that the
Collateral Agent's rights under this Security Agreement are not conditioned upon
pursuit by the Collateral Agent of any remedy the Collateral Agent or any of the
Lenders may have against the Borrower or any other person or any other security.
No invalidity, irregularity or unenforceability of any part or all of the
Several Obligations or any documents evidencing the same, by reason of any
bankruptcy, insolvency or other law or order of any kind or for any other
reasons, and no defense or setoff available at any time to the Borrower, shall
impair, affect or be a defense or setoff to the Collateral Agent's rights under
this Security Agreement.

     Company delivers this Security Agreement based solely on the Company's
independent investigation of (or decision not to 

                                       6
<PAGE>
 
investigate) the financial condition of the Borrower and the Account Parties and
is not relying on any information furnished by the Collateral Agent or any of
the Lenders. Company assumes full responsibility for obtaining any further
information concerning the Borrower's and each of the Account Parties' financial
condition, the status of the Several Obligations or any other matter which
Company may deem necessary or appropriate now or later. Company waives any duty
on the part of the Collateral Agent and each of the Lenders, and agrees that it
is not relying upon nor expecting the Collateral Agent or any of the Lenders, to
disclose to Company any fact now or later known by the Collateral Agent, whether
relating to the operations or condition of the Borrower or any Account Party,
the existence, liabilities or financial condition of any guarantor of the
Several Obligations, the occurrence of any default with respect to the Several
Obligations, or otherwise, notwithstanding any effect such fact may have upon
Company's risk under this Security Agreement or the Company's rights against the
Borrower or any Account Party. Company knowingly accepts the full range of risk
encompassed in this Security Agreement, which risk includes without limit the
possibility that Borrower or any Account Party may incur Several Obligations to
the Collateral Agent or any of the Lenders after the financial condition of the
Borrower or any Account Party, or Borrower's or any Account Party's ability to
pay debts as they mature, has deteriorated.

     Company represents that: (a) neither the Collateral Agent nor any Lender
has made any representation to Company as to the creditworthiness of the
Borrower or any Account Party; and (b) Company has established adequate means of
obtaining from the Borrower or any Account Party on a continuing basis financial
and other information pertaining to the Borrower's or any Account Party's
financial condition. Company acknowledges that neither Collateral Agent nor any
Lender has any obligation to keep Company adequately informed of any facts,
events or circumstances which might in any way affect the risks of Company under
this Security Agreement.

     Company acknowledges that the effectiveness of this Security Agreement is
not conditioned on any or all of the Several Obligations being guaranteed by
anyone else. Subject to the terms of the Intercreditor Agreement, Collateral
Agent, in its sole discretion, without notice to Company, may release, exchange,
enforce and otherwise deal with any security now or later held by the Collateral
Agent for payment of the Several Obligations without affecting in any manner the
Collateral Agent's rights under this Security Agreement. Company acknowledges
and agrees that neither the Collateral Agent nor any of the Lenders has any
obligation to acquire or perfect any lien on or security interest in any

                                       7
<PAGE>
 
asset(s), whether realty or personalty, to secure payment of the Several
Obligations, and Company is not relying upon assets in which Collateral Agent or
any of the Lenders has or may have a lien or security interest for payment of
the Several Obligations.

     Company irrevocably and absolutely waives any and all rights of
subrogation, contribution, indemnification, recourse, reimbursement and any
similar rights against the Borrower or any Account Party (or any other
guarantor) with respect to this Security Agreement, whether these rights arise
under an express or implied contract or by operation of law. It is the intention
of the parties that Company shall not be (or be deemed to be) a "creditor" (as
defined in Section 101 of the Federal Bankruptcy Code, as the same may be
amended) of the Borrower or any Account Party (or any other guarantor) by reason
of the existence of this Security Agreement in the event that the Borrower or
any Account Party becomes a debtor in any proceeding under the Federal
Bankruptcy Code. This waiver is given to induce the Collateral Agent and the
Lenders to enter into certain written contracts with the Borrower and the
Account Parties included in the Several Obligations. Company warrants and agrees
that none of Collateral Agent's or any of the Lenders' rights, remedies or
interests shall be directly or indirectly impaired because of any of Company's
status as an "insider" or "affiliate" of the Borrower or any Account Party, and
Company shall take any action or refrain from taking any action, and shall
execute any document, which the Collateral Agent may request in order to
effectuate this warranty to the Collateral Agent.

     Company may terminate the Collateral Agent's rights under this Security
Agreement as to future extensions of credit which would otherwise constitute
Several Obligations (except as provided below) by (and only by) delivering
written notice to an officer of the Collateral Agent and receiving from an
officer of the Collateral Agent written acknowledgment of the delivery;
provided, the termination shall not be effective until the opening of business
on the forty-fifth (45th) day following written acknowledgment of delivery. Any
termination shall not affect in any way the Collateral Agent's or any Lender's
rights under this Security Agreement as to any Several Obligations existing at
the effective date of termination of any Several Obligations created after that
pursuant to any commitment or agreement of the Collateral Agent or any Lender or
any Borrower or any Account Party loan with the Collateral Agent or any Lender
existing at the effective date of this termination (whether later advances or
readvances by the Lender are optional or obligatory), or any modifications,
extensions or renewals of any Several Obligations, whether in whole or in part,
and as to all this Several Obligations and 

                                       8
<PAGE>
 
modifications, renewals and extensions of it, this Security Agreement shall
continue to be effective until the same shall have been fully paid in cash.

     Notwithstanding any prior revocation, termination, surrender, or discharge
of this Security Agreement in whole or part, the effectiveness of this Security
Agreement shall automatically continue or be reinstated, as the case may be, in
the event that (a) any payment received or credit given by the Collateral Agent
or any of the Lenders in respect of the Several Obligations is returned,
disgorged, or rescinded as a preference, impermissible setoff, fraudulent
conveyance, diversion of trust funds, or otherwise under any applicable state or
federal law, including, without limitation, laws pertaining to bankruptcy or
insolvency, in which case this Security Agreement shall be enforceable against
Company as if the returned, disgorged, or rescinded payment or credit had not
been received or given by the Collateral Agent or such Lender, and whether or
not the Collateral Agent or such Lender relied upon this payment or credit or
changed its position as a consequence of it; or (b) any liability is imposed, or
sought to be imposed, against the Collateral Agent or any of the Lenders
relating to the environmental condition of, or the presence of hazardous or
toxic substances on, in or about, any property given as collateral to the
Collateral Agent or any of the Lenders for the Several Obligations, whether this
condition is known or unknown, now exists or subsequently arises (excluding only
conditions which arise after any acquisition by the Collateral Agent or any of
the Lenders of any such property, by foreclosure, in lieu of foreclosure or
otherwise, to the extent due to the wrongful act or omission of the Collateral
Agent or any of the Lenders), in which case this Security Agreement shall be
enforceable to the extent of all liability, costs and expenses (including
without limit reasonable attorneys' fees) incurred by the Collateral Agent or
any of the Lenders as the direct or indirect result of any environmental
condition or hazardous or toxic substances. For purposes of this Security
Agreement, "environmental condition" includes, without limitation, conditions
existing with respect to the surface or ground water, drinking water supply,
land surface or subsurface and the air; and "hazardous or toxic substances"
shall include any and all substances now or subsequently determined by any
federal, state or local authority to be hazardous or toxic, or otherwise
regulated by any of these authorities. Company will comply in all material
respects with all statutes, laws, ordinances and regulations relating to the
Collateral, including without limitation any registration requirements and all
federal, state and local environmental protection, toxic substance and other
similar laws and regulations applicable to Company's business or to any of the
Collateral or any premises where any of the Collateral is

                                       9
<PAGE>
 
located (Company hereby representing and warranting that, as of the date hereof,
it is in compliance with all such laws and regulations), and hold harmless and
indemnify Collateral Agent and each of the Lenders from and against any and all
liability or claims asserted against or suffered by Collateral Agent or any of
the Lenders as a result of any failure by Company to comply with this paragraph
(or any misrepresentation or breach of warranty hereunder), such indemnity to
survive any payoff and discharge of the Several Obligations.

     Company shall take or cause to be taken and execute or cause to be executed
all financing statements, endorsements, assignments and other writings requested
by Collateral Agent to establish, maintain, reinstate, and/or continue the
perfected and first priority status of the security interest of Collateral Agent
in the Collateral or implement or further effectuate the terms or purpose of
this Security Agreement, although the failure of Company to do so shall not
affect in any way Collateral Agent's perfected and first priority security
interest in the Collateral, and will on demand pay all costs and expenses of
filing and recording, including the costs of any record searches, deemed
necessary by Collateral Agent from time to time, to establish or determine the
validity and the priority of Lender's security interest. Company further makes,
constitutes and appoints Collateral Agent its true and lawful attorney-in-fact
with full power of substitution to take any action in furtherance of this
Security Agreement, including, without limitation, the signing of financing
statements, endorsing of instruments, and the execution and delivery of all
documents and agreements necessary to obtain or accomplish any protection for or
collection or disposition of any part of the Collateral. Such appointment shall
be deemed irrevocable and coupled with an interest and may be exercised only at
any time following the occurrence and during the continuance of a Default.

     Company waives any right to require the Collateral Agent or any of the
Lenders to: (a) proceed against any person, including without limit the Borrower
or any Account Party (b) proceed against or exhaust any security held from the
Borrower or any Account Party or any other person; (c) pursue any other remedy
in the Collateral Agent's or any of the Lenders' power; or (d) make any
presentments or demands for performance, or give any notices of nonperformance,
protests, notices of protest or notices of dishonor in connection with any
obligations or evidences of Several Obligations held by the Collateral Agent or
any of the Lenders as security, in connection with any other obligations or
evidences of Several Obligations which continues in whole or in part of the
Several Obligations secured under this Security Agreement, or in connection with
the creation of new or additional Several Obligations.

                                       10
<PAGE>
 
     Company waives any defense based upon or arising by reason of (a) any
disability or other defense of the Borrower, any Account Party or any other
person; (b) the cessation or limitation from any cause, other than final and
irrevocable payment in full, of the Several Obligations; (c) any lack of
authority of any officer, director, partner, agent or any other person acting or
purporting to act on behalf of the Borrower or any Account Party or any defect
in the formation of the Borrower or any Account Party; (d) the application by
the Debtor of the proceeds of any Several Obligations for purposes other than
the purposes represented by the Borrower or any Account Party to Collateral
Agent or any of the Lenders or intended or understood by the Collateral Agent or
any Account Party, the Lenders or Company; (e) any act or omission by the
Collateral Agent or any of the Lenders which directly or indirectly result in or
aids the discharge of the Borrower or any Account Party or any Several
Obligations by operation of law or otherwise; or (f) any modification of the
Several Obligations, in any form, including without limit the renewal,
extension, acceleration or other change in time for payment of the Several
Obligations, or other change in the terms of Several Obligations or any part of
it, including without limit increase or decrease of the rate of interest.
Company waives any defense Company may have based upon any election of remedies
by the Collateral Agent or any of the Lenders which destroys Company's
subrogation rights or Company's right to proceed against the Borrower or any
Account Party for reimbursement, including without limit any loss of rights
Company may suffer by reason of any rights, powers or remedies of the Borrower
of any Account Party in connection with any anti-deficiency laws or any other
laws limiting, qualifying or discharging the Several Obligations.

     Company acknowledges that the Collateral Agent, subject to the terms of the
Intercreditor Agreement, has the right to sell, assign, transfer, negotiate or
grant participations or any interest in, any or all of the Several Obligations
and any related obligations, including without limit this Security Agreement. To
the extent and in connection with the above, but without limiting its ability to
make other disclosures to the full extent allowable, the Collateral Agent or any
of the Lenders may disclose all documents and information which the Collateral
Agent or any of the Lenders now has or later acquires relating to Company, the
Several Obligations or this Security Agreement, however obtained. Company
further agrees that the Collateral Agent or any of the Lenders may disclose the
documents and information to the Borrower or any Account Party.

     This Security Agreement constitutes the entire agreement of Company and the
Collateral Agent with respect to the subject matter of this Security Agreement.
No waiver, consent, modification, or change of the terms of this Security
Agreement shall bind Company or Collateral Agent unless in writing and signed by
the waiving party or an authorized officer of the waiving party, and then this
waiver, consent, modification, or change shall be effective only in the specific
instance and for the specific purpose given. This Security Agreement shall inure
to the benefit of Collateral Agent, each of the Lenders and their successors and
assigns. This Security Agreement shall be binding on Company and Company's
successors, and assigns, including without limit any debtor in possession or
trustee in bankruptcy for Company. Company has entered into this Security
Agreement in good faith for the purpose of inducing the Lenders to extend credit
to make other financial accommodations to Borrower and the Account Parties and
Company acknowledges that the terms of this Security Agreement are reasonable.
If any provision of this Security Agreement is unenforceable in whole or in part
for any reason, the remaining provisions shall continue to be effective. THIS
