ITEM 2.  ACQUISITION OR DISPOSITION OF ASSETS

         Mid-Central Plastics, Inc.

         On May 29, 1998, the Company closed its acquisition of all of the
issued and outstanding shares of MidCentral Plastics, Inc. ("Mid-Central"). The
total purchase price was $23,825,000 (including debt assumed and refinanced),
which was paid in cash at the closing. The Company borrowed the necessary funds
under its new Credit Agreement described in Item 5, below. The selling
shareholders also received payments under noncompetition agreements totaling
$75,000. The purchase price was the result of arms length bargaining between
the Company and the owners of Mid-Central.
        
         Mid-Central, based in West Des Moines, Iowa, is an ISO 9002 registered
injection molder specializing in highly engineered products for construction,
agricultural, and industrial equipment manufacturers. Mid Central has
approximately 200 employees at its 113,000 square foot manufacturing facility.
Mid-Central operates 27 injection molding machines ranging in size from 85 to
1760 tons.

         The Company intends to maintain Mid-Central as a separate subsidiary
and to operate its assets in substantially the same manner in which Mid-Central
employed them before the acquisition.

         SMP Steel Corporation.

         On June 1, 1998, a wholly owned subsidiary of the Company acquired 
substantially all of the assets of SMP Steel Corporation ("SMP"), a privately 
held company located in Honea Path, South Carolina. The total purchase price 
was not material to the Company.

         SMP is a manufacturer of precision sheet metal components, enclosures,
and assemblies for original equipment manufacturers primarily located in the
Southeast. SMP's major capabilities include laser cutting, punching, folding,
forming, and welding. SMP primarily produces carbon steel and stainless steel
products, as well as a limited amount of aluminum products. The Company intends
to operate SMP's assets in substantially the same manner in which SMP employed
them before the acquisition.

ITEM 5.  OTHER EVENTS.

         On May 28, 1998, the Company entered into a new credit agreement with
Harris Trust and Savings Bank, as Agent. All subsidiaries of the Company,
including any subsequently acquired subsidiaries, are guarantors of the
Company's indebtedness. The credit agreement is a $90 million facility, with the
following components: (i) a $35 million revolving credit facility with a $10
million sub limit for letters of credit; (ii) a $25 million secured term loan
that matures 5 years from the date of the credit agreement closing; and (iii) a
$30 million secured term loan that matures 7 years from the date of the credit
agreement closing. Both term loans are fully amortized over their respective
terms with quarterly payments. The interest rates on the loans, at Morton's
option, are (i) Harris Trust and Savings Bank Base Rate (which is the greater of
the prime rate or the Federal Funds Rate plus 0.5%) or (ii) the reserve adjusted
LIBOR plus the applicable LIBOR margin, fixed for 30, 60, 90 or 180 day period,
plus an interest rate margin that is determined by the Company's cash flow
leverage ratio.

         The proceeds under the facility are to be used to refinance the
existing indebtedness, to finance acquisitions, and general corporate purposes.
The facility is fully secured by a first priority security interest in all of
the assets of the Company and the guarantors except for permitted liens, as well
as a pledge of all of the stock the Company's subsidiaries (including
subsequently acquired subsidiaries). The credit agreement requires that at least
50% of the term loans be hedged through an interest rate cap, swap or collar for
a minimum of three years from the date of closing. The conditions of the credit
agreement contain the usual conditions for facilities and transactions of this
type, including a prohibition on the payment of dividends.

                            STOCK PURCHASE AGREEMENT



     THIS STOCK PURCHASE AGREEMENT (the "Agreement") is made as of April 27,
1998, by and between Morton Industrial Group, Inc., a Georgia corporation
("Buyer"); Richard L. Goreham an individual resident of Des Moines, Iowa
("Richard"); Dolores A. Staples an individual resident of Des Moines, Iowa
("Dee"); and William B. Goreham, an individual resident of LaJolla, California

                                    RECITALS

     Sellers own that number of shares of Mid-Central Plastics, Inc., an Iowa
corporation (the "Company"), set opposite their respective names on Exhibit A
attached. Such shares are referred to herein as the "Shares," and constitute all
of the issued and outstanding shares of capital stock of Company. Sellers desire
to sell, and Buyer desires to purchase, the Shares for the consideration and on
the terms set forth in this Agreement.

may mutually agree. Subject to the provisions of Section 9, failure to
consummate the purchase and sale provided for in this Agreement on the date and
time and at the place determined pursuant to this Section 1.3 will not result in
the termination of this Agreement and will not relieve any party of any

Trust & Savings Bank of Peoria, Illinois or other escrow agent mutually
acceptable to the parties.

     1.5 ADJUSTMENT AMOUNT. The Adjustment Amount, but only if negative, will be
equal to (a) the stockholders' equity of the Company as of the Closing Date
determined in accordance with GAAP, minus (b) the stockholders' equity of the
Company as of December 31, 1997 as set forth in the Balance Sheet.

     1.6 ADJUSTMENT PROCEDURE.

     (a) Sellers shall prepare and cause Northrup, Haines, Kaduce, Schmid,
Marklin, P.C., the Company's certified public accountants, at Sellers' expense,
to audit, within sixty (60) days following the Closing Date, financial
statements ("Closing Financial Statements") of the Company as of the Closing
Date and for the period from the date of the Balance Sheet through the Closing
Date, including a computation of stockholders' equity as of the Closing Date. If
within thirty (30) days following delivery of the Closing Financial Statements,
Buyer has not given Sellers notice of its objection to the Closing Financial
Statements (such notice must contain a statement of the basis of Buyer's
objection), then the stockholders' equity reflected in the Closing Financial
Statements will be used in computing the Adjustment Amount. If Buyer gives such
notice of objection, then the issues in dispute will be submitted to McGladrey &
Pullen LLP, certified public accountants (the "Accountants"), for resolution. If
issues in dispute are submitted to the Accountants for resolution, (i) each
party will furnish to the Accountants such workpapers and other documents and
information relating to the disputed issues as the Accountants may request and
are available to that party (or its independent public accountants), and will be
afforded the opportunity to present to the Accountants any material relating to
the determination and to discuss the determination with the Accountants, (ii)
the determination by the Accountants, as set forth in a notice delivered to both
parties by the Accountants, will be binding and conclusive on the parties, and
(iii) Buyer and Sellers will each bear 50% of the fees of the Accountants for
such determination.

     (b) On the tenth (10th) business day following the final determination of
the Adjustment Amount, if the Purchase Price is less than the aggregate of the
payments made pursuant to Sections 1.4(b)(i) and 1.4(b)(ii) Sellers will pay the
difference to Buyer. All payments will be made together with interest at the
rate of 10% per annum beginning on the Closing Date and ending on the date of
payment.

     1.7 EMPLOYMENT AGREEMENTS. Immediately following the Closing, Buyer shall
cause the Company to offer Employment Agreements to certain of its key managers
in the form of the Agreements attached hereto as Exhibit 1.7.

Sellers, enforceable against Sellers in accordance with its terms. Upon the

with their respective terms. Sellers have the absolute and unrestricted right,
power, authority, and capacity to execute and deliver this Agreement and the
Sellers' Closing Documents and to perform their obligations under this Agreement

of this Agreement nor the consummation or performance of any of the Contemplated
Transactions will, directly or indirectly (with or without notice or lapse of

of the assets owned or used by, the Company;

          (iv) To the Knowledge of Sellers based on current tax law, cause Buyer
or the Company to become subject to, or to become liable for the payment of, any
Tax;

          (v) Contravene, conflict with, or result in a violation or breach of
any provision of, or give any Person the right to declare a default or exercise
any remedy under, or to accelerate the maturity or performance of, or to cancel,
terminate, or modify, any Applicable Contract; or

          (vi) Result in the imposition or creation of any Encumbrance upon or
with respect to any of the assets owned or used by the Company.

Except as set forth in Schedule 2.2, no Seller or the Company is or will be
required to give any notice to or obtain any Consent from any Person in
connection with the execution and delivery of this Agreement or the consummation
or performance of any of the Contemplated Transactions.

     2.3 CAPITALIZATION. The authorized equity securities of the Company
consists of 200,000 shares of Class A stock, par value $10.00 per share, and
200,000 shares of Class B stock, par value $10.00 per share. Of the authorized
shares, the number of issued and outstanding shares are as set forth in Schedule
2.3. Sellers are and will be on the Closing Date the record and beneficial
owners and holders of the Shares, free and clear of all Encumbrances. Each of
the Sellers owns the number of Shares set forth opposite his name on Exhibit A.
All of the outstanding equity securities of the Company have been duly
authorized and validly issued and are fully paid and nonassessable. There are no
Contracts relating to the issuance, sale, or transfer of any equity securities
or other securities of the Company. None of the outstanding equity securities or

or any other Legal Requirement. The Company does not own, or have any Contract
to acquire, any equity securities or other securities of any Person or any
direct or indirect equity or ownership interest in any other business.

(as recorded) by which the Company acquired such real property and interests,
and copies of all title insurance policies, opinions, abstracts, and surveys in

the properties and assets (whether real, personal, or mixed and whether tangible
or intangible) that they purport to own located in the facilities owned or
operated by the Company or reflected as owned in the books and records of the
Company, including all of the properties and assets reflected in the Balance
Sheet and the Interim Balance Sheet (except for assets held under capitalized
leases disclosed or not required to be disclosed in Schedule 2.6 and personal
property sold since the date of the Balance Sheet and the Interim Balance Sheet,
as the case may be, in the Ordinary Course of Business), and all of the
properties and assets purchased or otherwise acquired by the Company since the
date of the Balance Sheet (except for personal property acquired and sold since
the date of the Balance Sheet in the Ordinary Course of Business and consistent
with past practice). All material properties and assets reflected in the Balance
Sheet and the Interim Balance Sheet are free and clear of all Encumbrances and
are not, in the case of real property, subject to any rights of way, building
use restrictions, exceptions, variances, reservations, or limitations of any
nature except, with respect to all such properties and assets, (a) mortgages or
security interests shown on the Balance Sheet or the Interim Balance Sheet as
securing specified liabilities or obligations, with respect to which no default
(or event that, with notice or lapse of time or both, would constitute a
default) exists, (b) mortgages or security interests incurred in connection with
the purchase of property or assets after the date of the Interim Balance Sheet
(such mortgages and security interests being limited to the property or assets
so acquired), with respect to which no default (or event that, with notice or
lapse of time or both, would constitute a default) exists, (c) liens for current
taxes not yet due, and (d) with respect to real property, (i) minor
imperfections of title, if any, none of which is substantial in amount,
materially detracts from the value or impairs the use of the property subject
thereto, or impairs the operations of the Company, and (ii) zoning laws and
other land use restrictions that do not impair the present or anticipated use of
the property subject thereto. All buildings, plants, and structures owned by the
Company lie wholly within the boundaries of the real property owned by the
Company and do not encroach upon the property of, or otherwise conflict with the
property rights of, any other Person.

     2.7 CONDITION AND SUFFICIENCY OF ASSETS. To the Knowledge of Sellers, the
buildings, plants, structures, and equipment of the Company are structurally
sound, are in good operating condition and repair, and are adequate for the uses

<PAGE>   8

and none of such buildings, plants, structures, or equipment is in need of
maintenance or repairs except for ordinary, routine maintenance and repairs that
are not material in nature or cost. To the Knowledge of Sellers, the building,
plants, structures, and equipment of the Company are sufficient for the
continued conduct of the Company's businesses after the Closing in substantially
the same manner as conducted prior to the Closing.

     2.8 ACCOUNTS RECEIVABLE. All accounts receivable of the Company that are
reflected on the Balance Sheet or the Interim Balance Sheet or on the accounting
records of the Company as of the Closing Date (collectively, the "Accounts
Receivable") represent or will represent valid obligations arising from sales
actually made or services actually performed in the Ordinary Course of Business.
Unless paid prior to the Closing Date, the Accounts Receivable are or will be as
of the Closing Date current and collectible net of the respective reserves shown
on the Balance Sheet or the Interim Balance Sheet or on the accounting records
of the Company as of the Closing Date (which reserves are adequate and
calculated consistent with past practice and, in the case of the reserve as of
the Closing Date, will not represent a greater percentage of the Accounts
Receivable as of the Closing Date than the reserve reflected in the Interim
Balance Sheet represented of the Account Receivable reflected therein and will
not represent a material adverse change in the composition of such Accounts
Receivable in terms of aging). Subject to such reserves, each of the Accounts
Receivable either has been or will be collected in full, without any set-off,
within ninety (90) days after the day on which it first becomes due and payable.
There is no contest, claim, or right of set-off, other than returns in the
Ordinary Course of Business, under any Contract with any debtor of an Accounts
Receivable relating to the amount or validity of such Accounts Receivable.

obsolete items and items of below-standard quality, all of which have been
written off or written down to net realizable value in the Balance Sheet or the
Interim Balance Sheet or on the accounting records of the Company as of the
Closing Date, as the case may be. All inventories not written off have been
priced at the lower of cost or market on a first in, first out basis. The
quantities of each item of inventory (whether raw materials, work-in-process, or
finished goods) are not excessive, but are reasonable in the present
circumstances of the Company.

     2.10 NO UNDISCLOSED LIABILITIES. Except as set forth in Schedule 2.10, the
Company has no liabilities or obligations of any nature (whether known or
unknown and whether absolute, accrued,

other party's failure to comply with its obligations under this Agreement, the
terminating party's right to pursue all legal remedies will survive such
termination unimpaired.

capable of being acquired) about the accuracy or inaccuracy of or compliance
with, any such representation, warranty, covenant, or obligation. The waiver of
any condition based on the accuracy of any representation or warranty, or on the
performance of or compliance with any covenant or obligation, will not affect
the right to indemnification, reimbursement, or other remedy based on such
representations, warranties, covenants, and obligations.

unless on or before three (3) years after the Closing Date Sellers are given

                                     - 49 -
<PAGE>   50

before three (3) years after the Closing Date Buyer is given notice of a claim

     10.6 LIMITATIONS ON AMOUNT -- SELLERS. Sellers will have no liability (for

with respect to such matters exceeds $50,000, and then only for the amount by
which such Damages exceed $50,000, up to an aggregate maximum of $750,000 (the
"Cap"). In addition, Damages on account of any Breach of a covenant, obligation,
representation, or warranty regarding Taxes or Environmental, Health, and Safety
Liabilities shall not be limited by the Cap or applied in computing the amount
paid in satisfaction of the Cap. However, this Section 10.6 will not apply to

and warranty is made or any intentional Breach by either Seller of any covenant
or obligation, and Sellers will be jointly and severally liable for all Damages

     10.7 LIMITATIONS ON AMOUNT -- BUYER. Buyer will have no liability (for

respect to such Breaches.

     10.8 ESCROW. Upon notice to Sellers specifying in reasonable detail the
basis for such set-off, Buyer may give notice of a Claim in such amount under
the Escrow Agreement. Neither the exercise of nor the failure to give a notice
of a Claim under the Escrow Agreement will constitute an election of remedies or
limit Buyer in any manner in the enforcement of any other remedies that may be
available to it.

     10.9 PROCEDURE FOR INDEMNIFICATION -- THIRD PARTY CLAIMS; TAX AUDIT.

     (a) Promptly after receipt by an indemnified party under Section 10.2,
10.4, or (to the extent provided in the last sentence of Section 10.3) Section
10.3 of notice of the commencement of any Proceeding against it, such
indemnified party will, if a claim is to be made against an indemnifying party
under such section, give notice to the indemnifying party of the commencement of
such claim, but the failure to notify the indemnifying party will not relieve



                                     - 50 -
<PAGE>   51

the indemnifying party of any liability that it may have to any indemnified
party, except to the extent that the indemnifying party demonstrates that the
defense of such action is prejudiced by the indemnifying party's failure to give
such notice.

     (b) If any Proceeding referred to in Section 10.9(a) is brought against an
indemnified party and it gives notice to the indemnifying party of the
commencement of such Proceeding, the indemnifying party will, unless the claim
involves Taxes, be entitled to participate in such Proceeding and, to the extent
that it wishes (unless (i) the indemnifying party is also a party to such
proceeding and the indemnified party determines in good faith that joint
representation would be inappropriate, or (ii) the indemnifying party fails to
provide reasonable assurance to the indemnified party of its financial capacity
to defend such Proceeding and provide indemnification with respect to such
Proceeding), to assume the defense of such Proceeding with counsel satisfactory
to the indemnified party and, after notice from the indemnifying party to the
indemnified party of its election to assume the defense of such Proceeding, the
indemnifying party will not, as long as it diligently conducts such defense, be
liable to the indemnified party under this Section 10 for any fees of other
counsel or any other expenses with respect to the defense of such Proceeding, in
each case subsequently incurred by the indemnified party in connection with the
defense of such Proceeding, other than reasonable costs of investigation. If the
indemnifying party assumes the defense of a Proceeding, (i) it will be
conclusively established for purposes of this Agreement that the claims made in
that Proceeding are within the scope of and subject to indemnification; (ii) no
compromise or settlement of such claims may be effected by the indemnifying
party without the indemnified party's consent unless (A) there is no finding or
admission of any violation of Legal Requirements or any violation of the rights
of any Person and no effect on any other claims that may be made against the
indemnified party, and (B) the sole relief provided is monetary damages that are
paid in full by the indemnifying party; and (iii) the indemnifying party will
have no liability with respect to any compromise or settlement of such claims
effected without its consent. If notice is given to an indemnifying party of the
commencement of any proceeding and indemnifying party does not, within ten (10)
days after the indemnified party's notice is given, give notice to the
indemnified party of its election to assume the defense of such Proceeding, the
indemnifying party will be bound by any determination made in such Proceeding or
any compromise or settlement effected by the indemnified party.

     (c) Notwithstanding the foregoing, if an indemnified party determines in
good faith that there is a reasonable probability that a Proceeding may
adversely affect it other than as a result of monetary damages for which it
would be entitled to indemnification under this Agreement, the indemnified party
may, by notice to the indemnifying party, assume the exclusive right to defend,
compromise, or settle such Proceeding, but the indemnifying party 


                                     - 51 -
<PAGE>   52

will not be bound by any determination of a Proceeding so defended or any
compromise or settlement effected without its consent (which may not be
unreasonably withheld).

     (d) Sellers hereby consent to the non-exclusive jurisdiction of any court
in which a Proceeding is brought against any Indemnified Person for purposes of
any claim that an Indemnified Person may have under this Agreement with respect
to such Proceeding or the matters alleged therein, and agree that process may be
served on Sellers with respect to such claim anywhere in the world.

     (e) Notwithstanding the foregoing, Sellers shall assume the defense of the
Tax Audit after the Closing and shall be free to enter into any compromise or
settlement of it without the consent of the Company or the Buyer so long as the
Company or Buyer has no liability arising out of the same. Buyer will reasonably
cooperate in the defense. Funds from the escrow account created pursuant to the
Escrow Agreement may be used to defend and resolve the Tax Audit.

     10.10 PROCEDURE FOR INDEMNIFICATION -- OTHER CLAIMS. A claim for
indemnification for any matter not involving a third-party claim may be asserted
by notice to the party from whom indemnification is sought.

     11. GENERAL PROVISIONS

     11.1 EXPENSES. Except as otherwise expressly provided in this Agreement,
each party to this Agreement will bear its respective expenses incurred in
connection with the preparation, execution, and performance of this Agreement
and the Contemplated Transactions, including all fees and expenses of agents,
representatives, counsel, and accountants. Buyer will pay one-half and Sellers
will pay one-half of the HSR Act filing fee. Sellers will cause the Company not
to incur any out-of-pocket expenses in excess of $5,000.00 in connection with
this Agreement. In the event of termination of this Agreement, the obligation of
each party to pay its own expenses will be subject to any rights of such party
arising from a breach of this Agreement by another party.

     11.2 PUBLIC ANNOUNCEMENTS. Any public announcement or similar publicity
with respect to this Agreement or the Contemplated Transactions will be issued,
if at all, at such time and in such manner as Buyer determines. Unless consented
to by Buyer in advance or required by Legal Requirements, prior to the Closing
Sellers shall, and shall cause the Company to, keep this Agreement strictly
confidential and may not make any disclosure of this Agreement to any Person.
Sellers and Buyer will consult with each other concerning the means by which the
Company's employees, customers, and suppliers and others having dealings with
the Company will be informed of the Contemplated Transactions, and Buyer will
have the right to be present for any such communication.

     11.3 CONFIDENTIALITY. Between the date of this Agreement and the Closing
Date, Buyer and Sellers will maintain in confidence, and will cause the
directors, officers, employees, agents, and advisors of Buyer and the Company to
maintain in confidence, any written, oral, or other information obtained in
confidence from another party or the Company in connection with this Agreement
or the Contemplated Transactions, unless (a) such information is already known
to such party or to others not bound by a duty of confidentiality or such
information becomes publicly available through no fault of such party, (b) the
use of such information is necessary or appropriate in making any filing or
obtaining any consent or approval required for the consummation of the
Contemplated Transactions, or (c) the furnishing or use of such information is
required by or necessary or appropriate in connection with legal proceedings.

     If the Contemplated Transactions are not consummated, each party will
return or destroy as much of such written information as the other party may
reasonably request. Whether or not the Closing takes place, Sellers waive, and
will upon Buyer's request cause the Company to waive, any cause of action,
right, or claim arising out of the access of Buyer or its representatives to any
trade secrets or other confidential information of the Company except for the
intentional competitive misuse by Buyer of such trade secrets or confidential
information.

under this Agreement must be in writing and will be deemed to have been duly
given when (a) delivered by hand (with written confirmation of receipt), (b)

party may reasonably request for the purpose of carrying out the intent of this
Agreement and the documents referred to in this Agreement.

     11.6 WAIVER. The rights and remedies of the parties to this Agreement are
cumulative and not alternative. Neither the failure nor any delay by any party
in exercising any right, power, or privilege under this Agreement or the
documents referred to in this Agreement will operate as a waiver of such right,
power, or privilege, and no single or partial exercise of any such right, power,
or privilege will preclude any other or further exercise of such right, power,
or privilege or the exercise of any other right, power, or privilege. To the
maximum extent permitted by applicable law, (a) no claim or right arising out of
this Agreement or the documents referred to in this Agreement can be discharged
by one party, in whole or in part, by a waiver or renunciation of the claim or
right unless in writing signed by the other party; (b) no waiver that may be
given by a party will be applicable except in the specific instances for which
it is given; and (c) no notice to or demand on one party will be deemed to be a
waiver of any obligation of such party or of the right of the party giving such
notice or demand to take further action without notice or demand as provided in
this Agreement or the documents referred to in this Agreement.

     11.7 ENTIRE AGREEMENT AND MODIFICATION. This Agreement supersedes all prior
agreements between the parties with respect to its subject matter (including the
letter of intent between Buyer and Sellers dated March 4, 1998 and agreed to on
March 6, 1998, and the Confidentiality Agreement between the Company and the
Buyer dated April 17, 1998) and constitutes (along with the documents referred
to in this Agreement) a complete and exclusive statement of the terms of the
agreement between the parties with respect to its subject matter. This Agreement
may not be amended except by a written agreement executed by the party to be
charged with the amendment.

all respects upon, and inure to the benefit of the successors and permitted

                          MORTON INDUSTRIAL GROUP, INC.

                                CREDIT AGREEMENT



To Each of the Lenders Signatory Hereto


Ladies and Gentlemen:

           The undersigned, Morton Industrial Group, Inc., a Georgia corporation
(the "Borrower") applies to you for your several commitments, subject to all of
the terms and conditions hereof and on the basis of the representations and
warranties hereinafter set forth, to make a revolving credit (the "Revolving
Credit"), a term credit (the "Term Credit") and a swing line (the "Swing Line")
in each case available to the Borrower, all as more fully hereinafter set forth.


SECTION 1.              THE CREDITS.

           Section 1.1.    Revolving Credit.

           (a) Generally. Subject to the terms and conditions hereof, each
Lender severally agrees to extend credit to the Borrower on a revolving basis
under the Revolving Credit which may be availed of by the Borrower from time to
time, and borrowings thereunder may be repaid and used again, during the period
from the date hereof to and including the Termination Date, at which time the
commitments of the Lenders to extend credit under the Revolving Credit shall
expire. The maximum amount of the Revolving Credit which each Lender agrees to
extend to the Borrower, taken together, shall not exceed its Revolving Credit
Commitment. The Revolving Credit may be utilized by the Borrower in the form of
Revolving Loans and Letters of Credit, all as more fully hereinafter set forth;
provided, however, that the aggregate amount of Revolving Loans, L/C Obligations
and Swing Loans outstanding at any one time from the Borrower shall not exceed
the Revolving Credit Commitments then in effect. For all purposes of this
Agreement, where a determination of the unused or available amount of the
Revolving Credit Commitments is necessary, the Revolving Loans and L/C
Obligations shall be deemed to utilize the Revolving Credit Commitments then in
effect. The obligations of the Lenders hereunder are several and not joint, and
no Lender shall under any circumstances be obligated to extend credit under the
Revolving Credit in excess of its Revolving Credit Commitment.

           (b) Revolving Loans. Subject to the terms and conditions hereof, the
Revolving Credit may be availed of by the Borrower in the form of loans in U.S.
Dollars (individually a "Revolving Loan" and collectively the "Revolving
Loans"). Each Revolving Loan by the Lenders shall be in a minimum amount of
$500,000 or such greater amount which is an integral 
<PAGE>   8

multiple of $100,000, except to the extent Section 2 provides otherwise in the
case of LIBOR Portions. Each Revolving Loan shall be made pro rata by the
Lenders in accordance with the amounts of their respective Revolver Percentages.
Each advance made by a Lender of its pro rata share of each Revolving Loan shall
be evidenced by the same Revolving Credit Note of the Borrower (individually,
for each Lender, its "Revolving Credit Note" and collectively, for all the
Lenders, their "Revolving Credit Notes"), jointly and severally, payable to the
order of such Lender in the amount of its Revolving Credit Commitment, with each
Revolving Credit Note to be in the form (with appropriate insertions) attached
hereto as Exhibit A. Each Revolving Credit Note shall be dated the date of
issuance thereof, be expressed to bear interest as provided in Section 2 hereof
and be expressed to mature on the Termination Date. Without regard to the
principal amount of each Revolving Credit Note stated on its face, the actual
principal amount at any time outstanding and owing by the Borrower on account
thereof shall be the sum of all advances then or theretofore made thereon less
all payments of principal actually received.

           Section 1.2.    Term Credit.

           (a) Term A Loan. Subject to all of the terms and conditions hereof,
the Lenders severally agree to make a term loan in U.S. Dollars (the "Term A
Loan") to the Borrower under the Term Credit in an amount not to exceed their
Term A Credit Commitments. Term A Loan shall be disbursed in a single advance
made, if at all, on or before June 15, 1998, at which time the commitments of
the Lenders to make Term A Loan shall expire. Each Lender shall advance a pro
rata share of Term A Loan in accordance with the amounts of their respective
Term A Percentages. Each Lender's pro rata share of the Term A Loan shall be
evidenced by a Term A Note of the Borrower (individually a "Term A Note" and
collectively the "Term A Notes") payable to the order of such Lender in the
amount of its pro rata share of Term A Loan, each Term A Note to be in the form
(with appropriate insertions) attached hereto as Exhibit B. Each Term A Note
shall be expressed to mature in installments, commencing on September 30, 1998
and continuing on the last day of each calendar quarter occurring thereafter to
and including March 31, 2003 plus the final installment due on May 31, 2003,
with the principal installments on the Term A Notes to aggregate $500,000 per
installment through and including December 31, 1998, $1,000,000 per installment
thereafter and through and including December 31, 1999, $1,250,000 per
installment thereafter and through and including December 31, 2001, $1,500,000
per installment thereafter and through and including December 31, 2002,
$2,000,000 on March 31, 2003 and with the final principal installment on all the
Term A Notes to aggregate in an amount equal to all principal and interest not
sooner paid, and with the amount of each installment due on the Term A Note held
by each Lender to be equal to such Lender's Term A Percentage of such
installment.

           (b) Term B Loan. Subject to all of the terms and conditions hereof,
the Lenders severally agree to make a term loan in U.S. Dollars (the "Term B
Loan") to the Borrower under 


                                      -2-
<PAGE>   9

the Term Credit in an amount not to exceed their Term B Credit Commitments. Term
B Loan shall be disbursed in a single advance made, if at all, on or before June
15, 1998, at which time the commitments of the Lenders to make Term B Loan shall
expire. Each Lender shall advance a pro rata share of Term B Loan in accordance
with the amounts of their respective Term B Percentages. Each Lender's pro rata
share of Term B Loan shall be evidenced by a Term B Note of the Borrower
(individually a "Term B Note" and collectively the "Term B Notes") payable to
the order of such Lender in the amount of its pro rata share of Term B Loan,
each Term B Note to be in the form (with appropriate insertions) attached hereto
as Exhibit C. Each Term B Note shall be expressed to mature in twenty-eight (28)
installments, commencing on September 30, 1998 and continuing on the last day of
each calendar quarter occurring thereafter to and including March 31, 2005 plus
the final twenty-eighth installment due on May 31, 2005, with the principal
installments on the Term B Notes to aggregate $125,000 per installment through
and including June 30, 2003, $3,437,500 per installment thereafter and through
and including March 31, 2005 and with the final principal installment on all the
Term B Notes to aggregate in an amount equal to all principal and interest not
sooner paid, and with the amount of each installment due on the Term B Note held
by each Lender to be equal to such Lender's Term B Percentage of such
installment.

           Section 1.3.    Letters of Credit.

           (a) General Terms. Subject to the terms and conditions hereof, as
part of the Revolving Credit, the Agent shall issue standby and commercial
letters of credit (each a "Letter of Credit") for the account of the Borrower
(whether for its own account individually or also for the account of any
Subsidiary) in U.S. Dollars in an aggregate undrawn face amount up to the amount
of the L/C Commitment as then in effect; provided, however, that the aggregate
L/C Obligations at any time outstanding shall not exceed the difference between
the Revolving Credit Commitments in effect at such time and the aggregate
principal amount of Revolving Loans and Swing Loans then outstanding. Each
Letter of Credit shall be issued by the Agent, but each Lender shall be
obligated to reimburse the Agent for its Revolver Percentage of the amount of
each drawing thereunder and, accordingly, the undrawn face amount of each Letter
of Credit shall constitute usage of the Revolving Credit Commitment of each
Lender pro rata in accordance with each Lender's Revolver Percentage.

           (b) Applications. At any time before the Termination Date, the Agent
shall, at the request of the Borrower, issue one or more Letters of Credit for
the account of the Borrower (whether for its own account individually or also
for the account of any Subsidiary), in a form satisfactory to the Agent, in an
aggregate face amount as set forth above, upon the receipt of an application for
the Letter of Credit in the form customarily prescribed by the Agent duly
executed by the Borrower for whose account such Letter of Credit was issued
(each an "Application"). Each Letter of Credit issued hereunder which is a
standby letter of credit shall 

                                      -3-
<PAGE>   10

expire not later than the earlier of (i) twelve (12) months from the date of
issuance and each renewal or (ii) the Termination Date. Each Letter of Credit
issued hereunder which is a commercial letter of credit shall expire not later
than the earlier of (i) one hundred eighty (180) days from the date of issuance
and each renewal or (ii) the Termination Date. The current forms of the Agent's
Applications for standby and commercial Letters of Credit attached hereto as
Schedule 1.3 (Standby) and Schedule 1.3 (Commercial), respectively. The Agent
shall provide the Borrower and each Lender with copies of any new form of
Application that may, from time to time, be adopted by the Agent.
Notwithstanding anything contained in any Application to the contrary (i) the
Borrower shall be liable for all obligations in respect of each Letter of
Credit, (ii) the Borrower's obligation to pay fees in connection with each
Letter of Credit shall be as exclusively set forth in Section 3.1(b) hereof,
(iii) except during the continuance of an Event of Default, the Agent will not
call for the funding by the Borrower of any amount under a Letter of Credit, or
any other form of collateral security for the Borrower's obligations in
connection with such Letter of Credit, before being presented with a drawing
thereunder, and (iv) if the Agent is not timely reimbursed for the amount of any
drawing under a Letter of Credit on the date such drawing is paid, the
Borrower's obligation to reimburse the Agent for the amount of such drawing
shall bear interest (which the Borrower hereby promises to pay) from and after
the date such drawing is paid at a rate per annum equal to the sum of 2-1/4%
plus the Domestic Rate from time to time in effect. The Agent will promptly
notify the Lenders of each issuance by it of a Letter of Credit. If the Agent
issues any Letters of Credit with expiration dates that are automatically
extended unless the Agent gives notice that the expiration date will not so
extend beyond its then scheduled expiration date, the Agent will give such
notice of non-renewal before the time necessary to prevent such automatic
extension if before such required notice date (i) the expiration date of such
Letter of Credit if so extended would be after the Termination Date, (ii) the
Revolving Credit Commitments have been terminated or (iii) an Event of Default
exists and the Required Lenders have given the Agent instructions not to so
permit the extension of the expiration date of such Letter of Credit. The Agent
agrees to issue amendments to the Letter(s) of Credit increasing the amount, or
extending the expiration date, thereof at the request of the Borrower subject to
the conditions of Section 7 and the other terms of this Section 1.3. Without
limiting the generality of the foregoing, the Agent's obligation to issue, amend
or extend the expiration date of a Letter of Credit is subject to the conditions
of Section 7 and the other terms of this Section 1.3 and the Agent will not
issue, amend or extend the expiration date of any Letter of Credit if any Lender
notifies the Agent of any failure to satisfy or otherwise comply with such
conditions and terms and directs the Agent not to take such action.

           (c) The Reimbursement Obligation. Subject to Section 1.3(b) hereof,
the obligation of the Borrower to reimburse the Agent for all drawings under a
Letter of Credit (a "Reimbursement Obligation") shall be governed by the
Application related to such Letter of Credit, except that reimbursement of each
drawing shall be made in immediately available funds at the Agent's principal
office in Chicago, Illinois by no later than 12:30 p.m. (Chicago time) on 

                                      -4-
<PAGE>   11

the date when such drawing is paid or, if drawing was paid after 11:30 a.m.
(Chicago time), by the end of such day. If the Borrower does not make any such
reimbursement payment on the date due and the Participating Lenders fund their
participations therein in the manner set forth in Section 1.3(d) below, then all
payments thereafter received by the Agent in discharge of any of the relevant
Reimbursement Obligations shall be distributed in accordance with Section 1.3(d)
below.

           (d) The Participating Interests. Each Lender (other than the Lender
then acting as Agent in issuing Letters of Credit), by its acceptance hereof,
severally agrees to purchase from the Agent, and the Agent hereby agrees to sell
to each such Lender (a "Participating Lender"), an undivided percentage
participating interest (a "Participating Interest"), to the extent of its
Revolver Percentage, in each Letter of Credit issued by, and each Reimbursement
Obligation owed to, the Agent. Upon any failure by the Borrower to pay any
Reimbursement Obligation in respect of a Letter of Credit issued for the
Borrower's account at the time required on the date the related drawing is paid,
as set forth in Section 1.3(c) above, or if the Agent is required at any time to
return to the Borrower or to a trustee, receiver, liquidator, custodian or other
Person any portion of any payment of any Reimbursement Obligation, each
Participating Lender shall, not later than the Business Day it receives a
certificate in the form of Exhibit F hereto from the Agent to such effect, if
such certificate is received before 1:00 p.m. (Chicago time), or not later than
the following Business Day, if such certificate is received after such time, pay
to the Agent an amount equal to its Revolver Percentage of such unpaid or
recaptured Reimbursement Obligation together with interest on such amount
accrued from the date the related payment was made by the Agent to the date of
such payment by such Participating Lender at a rate per annum equal to (i) from
the date the related payment was made by the Agent to the date two (2) Business
Days after payment by such Participating Lender is due hereunder, the Federal
Funds Rate for each such day and (ii) from the date two (2) Business Days after
the date such payment is due from such Participating Lender to the date such
payment is made by such Participating Lender, the Domestic Rate in effect for
each such day. Each such Participating Lender shall thereafter be entitled to
receive its Revolver Percentage of each payment received in respect of the
relevant Reimbursement Obligation and of interest paid thereon, with the Agent
retaining its Revolver Percentage as a Lender hereunder.

         The several obligations of the Participating Lenders to the Agent under
this Section 1.3 shall be absolute, irrevocable and unconditional under any and
all circumstances whatsoever (except to the extent the Borrower is relieved from
its obligation to reimburse the Agent for a drawing under a Letter of Credit
because of the Agent's gross negligence or willful misconduct in determining
that documents received under the Letter of Credit comply with the terms
thereof) and shall not be subject to any set-off, counterclaim or defense to
payment which any Participating Lender may have or have had against the
Borrower, the Agent, any other Lender or any other Person whatsoever. Without
limiting the generality of the foregoing, such obligations 

                                      -5-
<PAGE>   12

shall not be affected by any Default or Event of Default or by any reduction or
termination of any Revolving Credit Commitment of any Lender, and each payment
by a Participating Lender under this Section 1.3 shall be made without any
offset, abatement, withholding or reduction whatsoever. The Agent shall be
entitled to offset amounts received for the account of a Lender under this
Agreement against unpaid amounts due from such Lender to the Agent hereunder
(whether as fundings of participations, indemnities or otherwise), but shall not
be entitled to offset against amounts owed to the Agent by any Lender arising
outside this Agreement.

           (e) Indemnification. Each Participating Lender shall, to the extent
of its respective Revolver Percentage, indemnify the Agent (to the extent not
reimbursed by the Borrower) against any cost, expense (including reasonable
counsel fees and disbursements), claim, demand, action, loss or liability
(except such as result from the Agent's gross negligence or willful misconduct)
that the Agent may suffer or incur in connection with any Letter of Credit. The
obligations of the Participating Lenders under this Section 1.3(d) and all other
parts of this Section 1.3 shall survive termination of this Agreement and of all
other L/C Documents.

           (f) Change in Laws. If the Agent or any Lender shall determine in
good faith that any change in any applicable law, regulation or guideline
(including, without limitation, Regulation D of the Board of Governors of the
Federal Reserve System) or any new law, regulation or guideline, or any
interpretation of any of the foregoing by any governmental authority charged
with the administration thereof or any central bank or other fiscal, monetary or
other authority having jurisdiction over the Agent or such Lender (whether or
not having the force of law), shall:

                   (i) impose, modify or deem applicable any reserve, special
         deposit or similar requirement against the Letters of Credit, or the
         Agent's or such Lender's or the liability of the Borrower with respect
         thereto; or

                  (ii) impose on the Agent or such Lender any penalty with
         respect to the foregoing or any other condition regarding this
         Agreement, the Applications or the Letters of Credit;

and the Agent or such Lender shall determine in good faith that the result of
any of the foregoing is to increase the cost (whether by incurring a cost or
adding to a cost) to the Agent or such Lender of issuing, maintaining or
participating in the Letters of Credit hereunder (without benefit of, or credit
for, any prorations, exemptions, credits or other offsets available under any
such laws, regulations, guidelines or interpretations thereof), then the
Borrower shall pay on demand to the Agent or such Lender from time to time as
specified by the Agent or such Lender such additional amounts as the Agent or
such Lender shall determine are sufficient to compensate and indemnify it for
such increased cost in respect of each such Letter of Credit; 

                                      -6-
<PAGE>   13

provided, however, that the Borrower shall not be obligated to pay any such
amount or amounts to the extent such additional cost was incurred or paid by
such Lender more than sixty (60) days prior to the date of the delivery of the
certificate referred to in the immediately following sentence (nothing herein to
impair or otherwise affect the Borrower's liability hereunder for costs
subsequently incurred or paid by such Lender).

           Section 1.4. Manner and Disbursement of Borrowings. (a) Generally.
The Borrower shall give written or telephonic notice to the Agent (which notice
shall be irrevocable once given and, if given by telephone, shall be promptly
confirmed in writing) by no later than 11:00 a.m. (Chicago time) on any Business
Day of each request for a Loan, in each case specifying the type of Loan
(whether a Revolving Loan or a Term Credit Loan) which is to be made, the amount
of such Loan and the date such Loan is to be made. The Agent shall promptly
notify each Lender of the Agent's receipt of each such notice. Each Loan shall
initially constitute part of the applicable Domestic Rate Portion except to the
extent the Company has otherwise timely elected as provided in Section 2 hereof.
Not later than 12:00 noon (Chicago time) on the date specified for any Loan to
be made by a Lender hereunder, such Lender shall make the proceeds of its pro
rata share of such Loan available to the Agent in Chicago in immediately
available funds. Subject to the provisions of Section 7 hereof, the proceeds of
each Loan shall be made available to the Borrower at the principal office of the
Agent in Chicago, Illinois, in immediately available funds, upon receipt by the
Agent from each Lender of its pro rata share of such Loan.

           (b) Reimbursement Obligation. In the event the Borrower fails to give
notice pursuant to Section 1.4(a) above of a Revolving Loan equal to the amount
of a Reimbursement Obligation and has not notified the Agent by 11:00 a.m.
(Chicago time) on the day such Reimbursement Obligation becomes due that it
intends to repay such Reimbursement Obligation through funds not borrowed under
this Agreement, the Borrower shall be deemed to have requested a Revolving Loan
constituting part of the Domestic Rate Portion on such day in the amount of the
Reimbursement Obligation then due, subject to Section 7.1 hereof, which
Revolving Loan shall be applied to pay the Reimbursement Obligation then due.

           (c) Agent Reliance on Bank Funding. Unless the Agent shall have been
notified by a Lender prior to 11:30 a.m. (Chicago time) on the date a Loan is to
be made hereunder that such Lender does not intend to make its pro rata share of
such Loan available to the Agent, the Agent may assume that such Lender has made
such share available to the Agent on such date and the Agent may in reliance
upon such assumption make available to the Borrower a corresponding amount. If
such corresponding amount is not in fact made available to the Agent by such
Lender and the Agent has made such amount available to the Borrower, the Agent
shall be entitled to receive such amount from such Lender forthwith upon the
Agent's demand, together with interest thereon in respect of each day during the
period commencing on the date such amount 

                                      -7-
<PAGE>   14

was made available to the Borrower and ending on but excluding the date the
Agent recovers such amount at a rate per annum equal to the effective rate
charged to the Agent for overnight federal funds transactions with member banks
of the federal reserve system for each day as determined by the Agent (or in the
case of a day which is not a Business Day, then for the preceding day). If such
amount is not received from such Lender by the Agent immediately upon demand,
the Borrower will, on demand, repay to the Agent the proceeds of the Loan
attributable to such Lender with interest thereon at a rate per annum equal to
the interest rate applicable to the relevant Loan, but without such payment
being considered a payment or prepayment of a Loan, so that the Borrower will
have no liability under Section 2.9 hereof with respect to such payment.

           Section 1.5. Manner of Obtaining Letters of Credit. The Borrower
shall provide at least four (4) Business Days' advance written notice to the
Agent of a Borrower's request for the issuance for the Borrower's account of a
Letter of Credit, such notice in each case to be accompanied by an Application
for such Letter of Credit properly completed and executed by the Borrower and in
the case of an extension or an increase in the amount of a Letter of Credit, a
written request therefor, in a form acceptable to the Agent, in each case,
together with the fees called for by this Agreement. The Agent shall promptly
notify each Lender of the Agent's receipt of each such notice.

           Section 1.6. The Swing Line. (a) Swing Loans. Subject to all of the
terms and conditions hereof, Harris Trust and Savings Bank ("Harris") agrees to
make loans in U.S. Dollars to the Borrower under the Swing Line ("Swing Loans")
which shall not in the aggregate at any time outstanding exceed the lesser of
(i) the Swing Line Commitment or (ii) the difference between the Revolving
Credit Commitments in effect at such time and the sum of Revolving Loans and L/C
Obligations outstanding at the time of computation. The Swing Line Commitment
shall be available to the Borrower and may be availed of by the Borrower from
time to time and borrowings thereunder may be repaid and used again during the
period ending on the Termination Date; provided that each Swing Loan must be
repaid on the last day of the Interest Period applicable thereto. All Swing
Loans shall be evidenced by a single promissory note of the Borrower issued to
Harris in the form of Exhibit D hereto (the "Swing Line Note"). Without regard
to the face principal amount of the Swing Line Note, the actual principal amount
at any time outstanding and owing by the Borrower on account of the Swing Line
Note during the period ending on the Termination Date shall be the sum of all
Swing Loans then or theretofore made thereon less all payments actually received
thereon during such period.

           (b) Payment. Each Swing Loan shall be due and payable on the last day
of the Interest Period selected therefor. The Borrower may voluntarily prepay
any Swing Loan bearing interest at the Domestic Rate before its maturity at any
time upon notice to Harris prior to 1:00 p.m. (Chicago time) on the date fixed
for prepayment, each such prepayment to be made by the 

                                      -8-
<PAGE>   15

payment of the principal amount to be prepaid and accrued interest thereon to
the date of prepayment; provided, however, the Borrower may not voluntarily
prepay any Swing Loan bearing interest at Harris' Quoted Rate before its
maturity.

           (c) Minimum Borrowing Amount. Each Swing Loan which bears interest
with reference to the Domestic Rate shall be in an amount not less than
$100,000. Each Swing Loan which bears interest at Harris' Quoted Rate shall be
in an amount not less than $500,000.

           (d) Interest on Swing Loans. Each Swing Loan shall bear interest at
(x) the sum of the Domestic Rate from time to time in effect plus the Applicable
Margin or (y) if the Borrower so elects in accordance with the following
provisions, Harris' Quoted Rate; provided, however, that if any Swing Loan is
not paid when due (whether by lapse of time, acceleration or otherwise) such
Swing Loan shall bear interest, whether before or after judgment, until payment
in full thereof through the end of the Interest Period then applicable thereto
at a rate per annum equal to the sum of two percent (2%) plus the interest rate
which would otherwise be applicable thereto and, thereafter, at a rate per annum
equal to the sum of two percent (2%) plus the Applicable Margin plus the
Domestic Rate from time to time in effect. Interest on each Swing Loan shall be
due and payable on the last day of each Interest Period applicable thereto, and
interest after maturity (whether by lapse of time, acceleration or otherwise)
shall be due and payable upon demand.

           (e) Requests for Swing Loans. The Borrower shall give Harris prior
notice (which may be written or oral) no later than 12:00 Noon (Chicago time) on
the date upon which the Borrower requests that any Swing Loan be made, of the
amount and date of such Swing Loan and the Interest Period selected therefor.
Within thirty (30) minutes after receiving such notice, Harris shall in its
discretion quote an interest rate to the Borrower at which Harris would be
willing to make such Swing Loan available to the Borrower for a given Interest
Period (the rate so quoted for a given Interest Period being herein referred to
as "Harris' Quoted Rate"). The Borrower acknowledges and agrees that the
interest rate quote is given for immediate and irrevocable acceptance, and if
the Borrower does not so immediately accept Harris' Quoted Rate for the full
amount requested by the Borrower for such Swing Loan, the Harris' Quoted Rate
shall be deemed immediately withdrawn and such Swing Loan shall bear interest at
the sum of the Applicable Margin plus the Domestic Rate from time to time in
effect. Subject to all of the terms and conditions hereof, the proceeds of such
Swing Loan shall be made available to the Borrower on the date so requested at
the offices of the Agent in Chicago, Illinois. Anything contained in the
foregoing to the contrary notwithstanding, (i) the obligation of Harris to make
Swing Loans shall be subject to all of the terms and conditions of this
Agreement and (ii) Harris shall not be obligated to make more than one Swing
Loan during any one day.

                                      -9-
<PAGE>   16

           (f) Refunding Loans. In its sole and absolute discretion, Harris may
at any time, on behalf of the Borrower (which hereby irrevocably authorizes
Harris to act on its behalf for such purpose) and with notice to the Borrower,
request each Lender to make a Revolving Loan constituting the Domestic Rate
Portion of the Revolving Credit Notes in an amount equal to such Lender's
Revolver Percentage of the amount of the Swing Loans outstanding on the date
such notice is given. Unless any of the conditions of Section 7.2 are not
fulfilled on such date, each Bank shall make the proceeds of its requested pro
rata share of such Revolving Loan available to Harris, in immediately available
funds, at Harris' principal office in Chicago, Illinois, before 12:00 Noon
(Chicago time) on the Business Day following the day such notice is given. The
proceeds of such Revolving Loan shall be immediately applied to repay the
outstanding Swing Loans; provided, however, that unless any Default or Event of
Default has occurred and is continuing or the Borrower otherwise permits, the
proceeds of such Revolving Loan shall not be applied to repay any outstanding
Swing Loan bearing interest at Harris' Quoted Rate prior to the end of the
Interest Period applicable thereto.

           (g) Participations. If any Lender refuses or otherwise fails to make
its pro rata share of a Revolving Loan when requested by Harris pursuant to
Section 1.6(f) above (because the conditions in Section 7.2 are not satisfied or
otherwise), such Lender will, by the time and in the manner such share of such
Revolving Loan was to have been funded to Harris, purchase from Harris an
undivided participating interest in the outstanding Swing Loans in an amount
equal to its Revolver Percentage of the aggregate principal amount of Swing
Loans that were to have been repaid with such Revolving Loans, provided no
purchase of a participation in a Swing Loan bearing interest at Harris' Quoted
Rate need be made until after expiration of the Interest Period applicable
thereto. Each Lender that so purchases a participation in a Swing Loan shall
thereafter be entitled to receive its Revolver Percentage of each payment of
principal received on the Swing Loan and of interest received thereon accruing
from the date such Bank funded to Harris its participation in such Loan. The
several obligations of the Lenders under this Section 1.6(g) shall be absolute,
irrevocable and unconditional under any and all circumstances whatsoever and
shall not be subject to any set-off, counterclaim or defense to payment which
any Lender may have or have had against the Borrower, any other Lender or any
other Person whatever. Without limiting the generality of the foregoing, such
obligations shall not be affected by any Default or Event of Default or by any
reduction or termination of the Commitments of any Lender, and each payment made
by a Lender under this Section 1.6(g) shall be made without any offset,
abatement, withholding or reduction whatsoever.


SECTION 2.     INTEREST AND CHANGE IN CIRCUMSTANCES.

           Section 2.1. Interest Rate Options. (a) Subject to the terms and
conditions of this Section 2, portions of the principal indebtedness evidenced
by the Revolving Credit Notes and Term Notes (all of the indebtedness evidenced
by such Notes, whether or not such Notes are of 

                                      -10-
<PAGE>   17

the same class, bearing interest at the same rate for the same period of time
being hereinafter referred to as a "Portion") may, at the option of the
Borrower, bear interest with reference to the Domestic Rate (the "Domestic Rate
Portion") or with reference to the Adjusted LIBOR ("LIBOR Portions"), and
Portions of a particular class of Notes may be converted from time to time from
one basis for such Notes to the other. All of the indebtedness evidenced by the
Revolving Credit Notes and Term Notes which is not part of a LIBOR Portion shall
constitute a single Domestic Rate Portion. All of the indebtedness evidenced by
the Revolving Credit Notes and Term Notes which bears interest with reference to
a particular Adjusted LIBOR for a particular Interest Period shall constitute a
single LIBOR Portion. Anything contained herein to the contrary notwithstanding,
the obligation of the Lenders to create, continue or effect by conversion any
LIBOR Portion shall be conditioned upon the fact that at the time no Default or
Event of Default shall have occurred and be continuing. The Borrower hereby
promises to pay interest on each Portion at the rates and times specified in
this Section 2.

           (b) Domestic Rate Portion. Each Domestic Rate Portion shall bear
interest (which the Borrower hereby promises to pay at the times herein
provided) at the rate per annum determined by adding the Applicable Margin to
the Domestic Rate as in effect from time to time, provided that if a Domestic
Rate Portion or any part thereof is not paid when due (whether by lapse of time,
acceleration or otherwise) such Portion shall bear interest (which the Borrower
hereby promises to pay at the times herein provided), before as well as after
judgment, until payment in full thereof at the rate per annum determined by
adding 2% to the interest rate which would otherwise be applicable thereto from
time to time. Interest on the Domestic Rate Portion shall be payable monthly on
the last day of each month in each year (commencing June 30, 1998) and at
maturity of the applicable Notes, and interest after maturity shall be due and
payable upon demand. Any change in the interest rate on the Domestic Rate
Portions resulting from a change in the Domestic Rate shall be effective on the
date of the relevant change in the Domestic Rate.

           (c) LIBOR Portions. Each LIBOR Portion shall bear interest (which the
relevant Borrower hereby promises to pay at the times herein provided) for each
Interest Period selected therefor at a rate per annum determined by adding the
Applicable Margin to the Adjusted LIBOR for such Interest Period, provided that
if any LIBOR Portion is not paid when due (whether by lapse of time,
acceleration or otherwise) such Portion shall bear interest (which the Borrower
hereby promises to pay at the times herein provided), whether before or after
judgment, until payment in full thereof through the end of the Interest Period
then applicable thereto at the rate per annum determined by adding 2% to the
interest rate which would otherwise be applicable thereto, and effective at the
end of the Interest Period such LIBOR Portion shall automatically be converted
into and added to the Domestic Rate Portion and shall thereafter bear interest
at the interest rate applicable to the Domestic Rate Portion of the applicable
Notes after default. Interest on each LIBOR Portion shall be due and payable on
the 

                                      -11-
<PAGE>   18

last day of each Interest Period applicable thereto and, with respect to any
Interest Period applicable to a LIBOR Portion in excess of three (3) months, on
the date occurring every three (3) months after the date such Interest Period
began and at the end of such Interest Period, and interest after maturity shall
be due and payable upon demand. The Borrower shall notify the Agent on or before
11:00 a.m. (Chicago time) on the third Business Day preceding the end of an
Interest Period applicable to a LIBOR Portion whether such LIBOR Portion is to
continue as a LIBOR Portion, in which event the Borrower shall notify the Agent
of the new Interest Period selected therefor, and in the event the Borrower
shall fail to so notify the Agent, such LIBOR Portion shall automatically be
converted into and added to the Domestic Rate Portion of the applicable Notes as
of and on the last day of such Interest Period. The Agent shall promptly notify
each Lender of each notice received from the Borrower pursuant to the foregoing
provision.

           Section 2.2. Minimum Amounts. Each LIBOR Portion shall be in a
minimum amount of $1,000,000 or such greater amount which is an integral
multiple of $100,000.

           Section 2.3. Computation of Interest. All interest on each LIBOR
Portion shall be computed on the basis of a year of 360 days for the actual
number of days elapsed. All interest on the Domestic Rate Portion shall be
computed on the basis of a year of 365 days (or, in a leap year, 366 days) for
the actual number of days elapsed.

           Section 2.4. Manner of Rate Selection. The Borrower shall notify the
Agent by 11:00 a.m. (Chicago time) at least three (3) Business Days prior to the
date upon which it requests that any LIBOR Portion be created or that any part
of the Domestic Rate Portion be converted into a LIBOR Portion (each such notice
to specify in each instance the amount thereof and the Interest Period selected
therefor), and the Agent shall advise each Lender of each notice by 2:00 p.m.
(Chicago time) on the same Business Day the Agent receives such notice. If any
request is made to convert a LIBOR Portion into the Domestic Rate Portion, such
conversion shall only be made so as to become effective as of the last day of
the Interest Period applicable thereto. All requests for the creation,
continuance or conversion of Portions under this Agreement shall be irrevocable.

           Section 2.5. Change of Law. Notwithstanding any other provisions of
this Agreement or of the Notes, if at any time any Lender shall determine in
good faith that any change in applicable laws, treaties or regulations or in the
interpretation thereof makes it unlawful for such Lender to create or continue
to maintain any LIBOR Portion, it shall promptly so notify the Agent (which
shall in turn promptly notify the Borrower and the other Lenders) and the
obligation of such Lender to create, continue or maintain LIBOR Portions under
this Agreement shall terminate until it is no longer unlawful for such Lender to
create, continue or maintain LIBOR Portions. The Borrower, on demand, shall, if
the continued maintenance of 

                                      -12-
<PAGE>   19

any such LIBOR Portion is unlawful, thereupon prepay the outstanding principal
amount of the affected LIBOR Portions, together with all interest accrued
thereon and all other amounts payable to the affected Lender with respect
thereto under this Agreement; provided, however, that the Borrower may instead
elect to convert the principal amount of the affected LIBOR Portion into the
Domestic Rate Portion of the applicable Notes, subject to the terms and
conditions of this Agreement.

           Section 2.6. Unavailability of Deposits or Inability to Ascertain
Adjusted LIBOR. Notwithstanding any other provision of this Agreement or of the
Notes, if prior to the commencement of any Interest Period:

                   (a) the Agent or Required Lenders in good faith determine
           that deposits in the amount of any LIBOR Portion scheduled to be
           outstanding during such Interest Period are not readily available to
           the Lenders in the relevant market;

                   (b) the Agent or Required Lenders in good faith determine
           that by reason of circumstances affecting the relevant market,
           adequate and reasonable means do not exist for ascertaining Adjusted
           LIBOR; or

                   (c) the Agent or Required Lenders in good faith determine
           that (i) LIBOR as determined by the Agent will not adequately and
           fairly reflect the cost to the Lenders of funding their LIBOR
           Portions for such Interest Period and (ii) the Lenders' rights to
           payment under Section 2.7 hereof will not reasonably compensate them
           for such inadequate or unfair reflection of such cost;

then the Agent or Required Lenders, as the case may be, shall promptly give
notice thereof to the other Lenders and the Company and the obligations of the
Lenders to create, continue or effect by conversion any LIBOR Portion in such
amount and for such Interest Period shall terminate until deposits in such
amount and for the Interest Period selected by or on behalf of the relevant
Borrower shall again be readily available in the relevant market and adequate
and reasonable means exist for ascertaining Adjusted LIBOR.

           Section 2.7. Taxes and Increased Costs. With respect to any LIBOR
Portion, if any Lender shall determine in good faith that any change in any
applicable law, treaty, regulation or guideline (including, without limitation,
Regulation D of the Board of Governors of the Federal Reserve System) or any new
law, treaty, regulation or guideline, or any interpretation of any of the
foregoing by any governmental authority charged with the administration thereof
or any central bank or other fiscal, monetary or other authority having
jurisdiction over such Lender or its lending branch or the LIBOR Portions
contemplated by this Agreement (whether or not having the force of law) shall:

                                      -13-
<PAGE>   20

                   (i) impose, increase, or deem applicable any reserve, special
           deposit or similar requirement against assets held by, or deposits in
           or for the account of, or loans by, or any other acquisition of funds
           or disbursements by, such Lender which is not in any instance already
           accounted for in computing Adjusted LIBOR;

                   (ii) subject such Lender, any LIBOR Portion or a Note to the
           extent it evidences such a Portion, to any tax (including, without
           limitation, any United States interest equalization tax or similar
           tax however named applicable to the acquisition or holding of debt
           obligations and any interest or penalties with respect thereto),
           duty, charge, stamp tax, fee, deduction or withholding in respect of
           this Agreement, any LIBOR Portion or a Note to the extent it
           evidences such a Portion, except such taxes as may be measured by the
           overall net income or gross receipts of such Lender or its lending
           branches and imposed by the jurisdiction, or any political
           subdivision or taxing authority thereof, in which such Lender's
           principal executive office or its lending branch is located;

                   (iii) change the basis of taxation of payments of principal
           and interest due from the Borrower to such Lender hereunder or under
           a Note to the extent it evidences any LIBOR Portion (other than by a
           change in taxation of the overall net income or gross receipts of
           such Lender); or

                   (iv) impose on such Lender any penalty with respect to the
           foregoing or any other condition regarding this Agreement, the
           disbursement of credit hereunder, any LIBOR Portion or a Note to the
           extent it evidences any LIBOR Portion;

and such Lender shall determine that the result of any of the foregoing is to
increase the cost (whether by incurring a cost or adding to a cost) to such
Lender of creating or maintaining any LIBOR Portion hereunder or to reduce the
amount of principal or interest received or receivable by such Lender (without
benefit of, or credit for, any prorations, exemption, credits or other offsets
available under any such laws, treaties, regulations, guidelines or
interpretations thereof), then the Borrower shall pay on demand to such Lender
from time to time as specified by such Lender such additional amounts as such
Lender shall reasonably determine are sufficient to compensate and indemnify it
for such increased cost or reduced amount; provided, however, that the Borrower
shall not be obligated to pay any such amount or amounts to the extent such
additional cost or payment was incurred or paid by such Lender more than sixty
(60) days prior to the date of the delivery of the certificate referred to in
the immediately following sentence (nothing herein to impair or otherwise affect
the Borrower's liability hereunder for costs or payments subsequently incurred
or paid by such Lender). If a Lender makes such a claim for compensation, it
shall provide to the Borrower (with a copy to the Agent) a certificate setting
forth the computation of the increased cost or reduced amount as a result of any
event 

                                      -14-
<PAGE>   21

mentioned herein in reasonable detail and such certificate shall be conclusive
if reasonably determined.

           Section 2.8. Change in Capital Adequacy Requirements. If any Lender
shall determine that the adoption after the date hereof of any applicable law,
rule or regulation regarding capital adequacy, or any change in any existing
law, rule or regulation, or any change in the interpretation or administration
thereof by any governmental authority, central bank or comparable agency charged
with the interpretation or administration thereof, or compliance by such Lender
(or any of its branches or any corporation controlling such Lender) with any
request or directive regarding capital adequacy (whether or not having the force
of law) of any such authority, central bank or comparable agency, has or would
have the effect of reducing the rate of return on such Lender's or such
corporation's capital, as the case may be, as a consequence of such Lender's
obligations hereunder or for the credit which is the subject matter hereof to a
level below that which such Lender or such corporation could have achieved but
for such adoption, change or compliance (taking into consideration such Lender's
or such corporation's policies with respect to liquidity and capital adequacy)
by an amount deemed by such Lender to be material, then from time to time,
within fifteen (15) days after demand by such Lender, the Borrower shall pay to
the Lender such additional amount or amounts reasonably determined by such
Lender as will compensate such Lender for such reduction; provided, however,
that the Borrower shall not be obligated to compensate such Lender to the extent
its rate of return was so reduced more than sixty (60) days prior to the date of
such demand (nothing herein to impair or otherwise affect the Borrower's
liability hereunder to compensate for subsequent reductions in such Lender's
rate of return).

           Section 2.9. Funding Indemnity. In the event any Lender shall incur
any loss, cost or expense (including, without limitation, any loss, cost or
expense incurred by reason of the liquidation or reemployment of deposits or
other funds acquired or contracted to be acquired by such Lender to fund or
maintain its part of any Fixed Rate Loan or the relending or reinvesting of such
deposits or other funds or amounts paid or prepaid to such Lender) as a result
of:

                   (i) any payment of a Fixed Rate Loan on a date other than the
           last day of the then applicable Interest Period for any reason,
           whether before or after default, and whether or not such payment is
           required by any provisions of this Agreement; or

                   (ii) any failure by any Borrower to create, borrow, continue
           or effect by conversion a Fixed Rate Loan on the date specified in a
           notice given pursuant to this Agreement, unless such failure results
           from the Lenders' inability or unwillingness pursuant to Sections 2.5
           and 2.6 hereof to create, continue or effect by conversion a LIBOR
           Portion;

                                      -15-
<PAGE>   22

then, upon the demand of such Lender, the Borrower shall pay to such Lender such
amount as will reimburse such Lender for such loss, cost or expense. If a Lender
requests such a reimbursement, it shall provide to the Borrower (with a copy to
the Agent) a certificate setting forth the computation of the loss, cost or
expense giving rise to the request for reimbursement in reasonable detail and
such certificate shall be conclusive if reasonably determined; provided,
however, that the Borrower shall not be obligated to pay any such amount or
amounts to the extent such loss, cost or expense was incurred by such Lender
more than sixty (60) days prior to the date of the delivery of such certificate
(nothing herein to impair or otherwise affect the Borrower's liability hereunder
to compensate for any subsequent loss, cost, or expense incurred by such
Lender).

           Section 2.10. Lending Branch. Each Lender may, at its option, elect
to make, fund or maintain its pro rata share of the Loans hereunder at the
branches or offices specified on the signature pages hereof or on any Assignment
Agreement executed and delivered pursuant to Section 12.15 hereof or at such of
its branches or offices as such Lender may from time to time elect.

           Section 2.11. Lender's Duty to Mitigate. Each Lender agrees that, as
promptly as practicable after it becomes aware of the occurrence of an event or
the existence of a condition that would cause it to be affected under Section
2.5, 2.6 or 2.7 hereof, such Lender will, after notice to the Borrower, to the
extent not inconsistent with such Lender's internal policies and customary
business practices, use its best efforts to make, fund or maintain the affected
LIBOR Portion or issue or participate in the affected Letter of Credit, as the
case may be, through another lending office of such Lender if as a result
thereof the unlawfulness which would otherwise require payment of such Portion
pursuant to Section 2.5 hereof would cease to exist or the circumstances which
would otherwise terminate such Lender's obligation to make such Portion under
Section 2.6 hereof would cease to exist or the increased costs which would
otherwise be required to be paid in respect of such Portion or Letter of Credit
pursuant to Section 2.7 hereof would be materially reduced, and if, as
determined by such Lender, in its sole discretion, the making, funding or
maintaining of such Portion, or issuance or participation in such Letter of
Credit, as the case may be, through such other lending office would not
otherwise adversely affect such Portion or such Lender. The Borrower hereby
agrees to pay all reasonable expenses incurred by each such Lender in utilizing
another lending office pursuant to this Section 2.11.

           Section 2.12. Discretion of Lenders as to Manner of Funding.
Notwithstanding any provision of this Agreement to the contrary, each Lender
shall be entitled to fund and maintain its funding of all or any part of its
Notes in any manner it sees fit, it being understood, however, that for the
purposes of this Agreement all determinations hereunder (including, without
limitation, determinations under Sections 2.5, 2.6, 2.7 and 2.9 hereof) shall be
made as if each 

                                      -16-
<PAGE>   23

Lender had actually funded and maintained each LIBOR Portion during each
Interest Period applicable thereto through the purchase of deposits in the
relevant market in the amount of its share of such LIBOR Portion, having a
maturity corresponding to such Interest Period, and bearing an interest rate
equal to the LIBOR for such Interest Period.

           Section 2.13. Replacement of Lender. (a) In the event that (x) the
Borrower receives from a Lender a certificate requesting an amount be paid to
such Lender under Section 1.3(f), 2.7 or 2.8 hereof and the Required Lenders
have not similarly made requests for payment arising out of the same
circumstances or (y) the obligation of any Lender to make or maintain any LIBOR
Portion has terminated under Section 2.5 or 2.6 hereof and the obligations of
the Required Lenders to make or maintain LIBOR Portions have not similarly
terminated by reason of the same circumstances or (z) any Lender becomes a
Defaulting Lender, then the Borrower may request other Lenders hereunder to
assume in full the Commitments then in effect of the Lender requesting such
amount be paid or whose obligations with respect to LIBOR Portions have so
terminated or of such Defaulting Lender, as the case may be (such Lender in each
case being herein referred to as the "Replaceable Lender"), and to purchase the
Notes issued to the Replaceable Lender at a price equal to the outstanding
principal amount of such Notes and the Replaceable Lender's share of any accrued
and unpaid interest on such Notes plus accrued and unpaid commitment fees owed
to the Replaceable Lender, and if any Lender or Lenders (each an "Assuming
Lender") in their sole discretion agree so to assume in full the Commitments of
the Replaceable Lender (provided only one Assuming Lender shall assume the Swing
Line Commitment, if relevant), and after payment by the Borrower to the
Replaceable Lender of all amounts due under this Agreement to such Lender
(including any amount specified as due in a certificate submitted under Section
1.3(f), 2.7 or 2.8 hereof) not so paid by the Assuming Lender, then such
assumption shall take place in the manner set forth in subsection (b) below. In
the event no Lender or Lenders agrees to assume in full the Commitments of the
Replaceable Lender, then the Borrower may nominate one or more Lenders not then
party to this Agreement so to assume in full the Commitments of the Replaceable
Lender, and if such nominated Lender or Lenders are acceptable to the Agent and
Required Lenders (excluding the Replaceable Lender), such assumption shall take
place in the manner set forth in subsection (b) below and each such Lender or
Lenders shall become a Lender hereunder (each a "New Lender") and the
Replaceable Lender shall no longer be a party hereto or have any rights
hereunder.

           (b) In the event a Replaceable Lender's Commitments are to be assumed
in full by an Assuming Lender or a New Lender, then such assumption shall take
place on a date acceptable to the Borrower, the Replaceable Lender and the
Assuming Lender or New Lender, as the case may be, and such assumption shall
take place through the payment of all amounts due under this Agreement to the
Replaceable Lender and the execution of such instruments and documents as shall,
in the reasonable opinion of the Agent, be reasonably necessary or appropriate
for the Assuming Lender or New Lender to assume in full the Commitments of the
Replaceable Lender 

                                      -17-
<PAGE>   24

(including, without limitation, the issuance of new Notes and the execution of
an amendment hereto making any New Lender a party hereto). In the event no
Assuming Lender or New Lender agrees to assume in full the Commitments of the
Replaceable Lender, then such Replaceable Lender shall remain a party hereto and
its Commitments shall remain in effect.

           (c) The rights and remedies against a Defaulting Lender under this
Agreement, including without limitation this Section 2.13, are in addition to
other rights and remedies that the Borrower may have against such Defaulting
Lender with respect to any Loan which such Defaulting Lender has not funded, and
that the Agent, or any Lender may have against such Defaulting Lender with
respect to any such Loan.




SECTION 3.      FEES, PREPAYMENTS, TERMINATIONS, APPLICATIONS AND NOTATIONS.

           Section 3.1.    Fees.

           (a) Commitment Fee. For the period from and including the date hereof
to but not including the Termination Date, the Borrower shall pay to the Agent
for the ratable benefit of the Lenders as hereinafter set forth, a commitment
fee at the Applicable Margin (computed on the basis of a year of 360 days for
the actual number of days elapsed) on the average daily Unused Revolving Credit
Commitments. Such commitment fee shall be payable quarterly in arrears on the
last day of each March, June, September and December in each year (commencing
June 30, 1998) and on the Termination Date. Such commitment fee shall be
allocated among the Lenders ratably in accordance with the amount of their
respective Revolving Credit Commitments which is not in use in the form of
Revolving Loans, but with Swing Loans to be deemed Revolving Loans which use
exclusively the Revolving Credit Commitment of Harris (or if different, any
other Lender which then holds the Swing Line Commitment).

           (b) Letter of Credit Fees. On the date of issuance or extension, or
increase in the amount, of each Letter of Credit pursuant to Section 1.3 hereof,
the Borrower shall pay to the Agent for its own account an issuance fee equal to
 .125% of the face amount of (or the increase in the face amount of) such Letter
of Credit. On the last day of each calendar quarter (commencing on June 30,
1998) to, and on, the Termination Date, the Borrower shall pay to the Agent for
the ratable benefit of the Lenders in accordance with their percentages a fee
equal to the Applicable Margin for LIBOR Portions of the Revolving Loans
(computed on the basis of a year of 360 days for the actual number of days
elapsed) on the average daily outstanding undrawn amounts during the immediately
preceding calendar quarter of the Letters of Credit. In addition to the letter
of credit fees called for above, the Borrower further agrees to pay to the Agent
for its own account such processing and transaction fees and charges as the
Agent from 

                                      -18-

thereunder.

           (c) Audit Fees. The Borrower shall pay to the Agent for its own use
and benefit charges for audits of the Collateral by the Agent or its agents or
representatives in such amounts as the Agent may from time to time request (the
Agent acknowledging and agreeing that such charges shall be computed in the same
manner as it at the time customarily uses for the assessment of charges for
similar collateral audits actually performed by it); provided, however, that in
the absence of any Default or Event of Default, (i) the Borrower shall not be
required to reimburse the Agent for more than two (2) such audits per year (a
"Scheduled Field Audit") plus one (1) audit of each target of an Acquisition and
(ii) the Borrower shall in no event be liable for more than $5,000 for any one
Scheduled Field Audit.

           (d) Agent's Fee. The Borrower shall pay to the Agent the fees agreed
to in a letter exchanged between them.

           Section 3.2. Voluntary Prepayments of Revolving Credit and Term
Notes.

           (a) Revolving Credit Notes. The Borrower shall have the privilege of
prepaying the Revolving Credit Notes in whole or in part (but if in part, then
in a minimum amount of $100,000 or such greater amount which is an integral
multiple of $100,000) on any Business Day upon notice thereof to the Agent not
later than 11:00 a.m. (Chicago time) on such day, the Agent to promptly so
notify the Lenders, by the Borrower paying to the Agent for the account of the
Lenders the principal amount to be prepaid and (i) if such a prepayment prepays
such Notes in full and is accompanied by the termination in whole of the
Revolving Credit Commitments pursuant to which such Notes were issued, accrued
interest thereon to the date of prepayment plus any commitment fee which has
accrued and is unpaid and (ii) any amount due the Lenders under Section 2.9
hereof. Any amount so prepaid on the Revolving Credit Notes may, subject to the
terms and conditions of this Agreement, be reborrowed.

           (b) Term Notes. The Borrower shall have the privilege of prepaying
the Term Notes in whole or in part (but if in part, then in a minimum amount of
$100,000 or such greater amount which is an integral multiple of $100,000 as to
any particular class of Term Notes being prepaid) at any time upon one (1)
Business Day's prior notice to the Agent (such notice, if received subsequent to
11:00 a.m. (Chicago time) on a given day, to be treated as though received at
the opening of business on the next Business Day), which shall promptly so
notify the Lenders, by paying to the Agent for the account of the Lenders the
principal amount to be prepaid and (i) if such a prepayment prepays such Notes
in full, accrued interest thereon to the date of prepayment and (ii) any amounts
due to the Lenders under Section 2.9 hereof. Voluntary prepayments of the
principal of each class of the Term Notes shall be applied in several
installments thereof due on 

                                      -19-
<PAGE>   26

such class of Notes in the inverse order of their respective maturities. No
amount paid or prepaid on the Term Notes may be reborrowed.

           Section 3.3.    Mandatory Prepayments.

           (a) Excess Cash Flow. No later than April 30 of each calendar year
(commencing April 30, 1999), the Borrower shall pay over to the Agent for the
ratable benefit of the Lenders, as and for a mandatory prepayment on the Term
Notes an amount equal to 75% (the "Cash Flow Recapture Percentage") of Excess
Cash Flow for the then most recently completed fiscal year. Notwithstanding
anything contained herein to the contrary, if (i) the Cash Flow Leverage Ratio
is less than 3.00 to 1.00 for any two consecutive fiscal quarters of the
Borrower and (ii) no Default or Event of Default shall have occurred and then be
continuing, the Cash Flow Recapture Percentage shall be permanently reduced to
50%.

           (b) Equity Offering. Within five (5) Business Days of receipt by the
Borrower of cash proceeds from any public offering or private placement of any
capital stock or other equity securities of the Borrower (other than proceeds
from (i) any sale of capital stock of Borrower pursuant to an employee stock
ownership plan or (ii) any sale of capital stock of Borrower, or any options to
acquire any such stock, to officers, directors or key employees of the Borrower
or any of its Subsidiaries as compensation for services rendered or (iii) any
exercise by such officers or directors of such options), the Borrower shall make
a mandatory prepayment in an amount equal to 100% of the net cash proceeds of
such issuance (net only of underwriting discounts and commissions and any other
reasonable out-of-pocket costs and expenses directly incurred and payable in
connection therewith).

           (c) Asset Sales. Any and all proceeds derived from the sale or
disposition (whether voluntary or involuntary), or on account of damage or
destruction, of the real estate, furniture, fixtures, equipment or other fixed
assets of the Borrower or any Subsidiary shall be paid over to the Agent as and
for a mandatory prepayment on the Term Notes; provided, however, that (i) the
foregoing provisions shall be inapplicable to proceeds received by the Agent
under the Collateral Documents if and so long as, pursuant to the terms of the
Collateral Documents, the same are to be held by the Agent and disbursed for the
restoration, repair or replacement of the property in respect of which such
proceeds were received, (ii) no prepayment shall be required with respect to the
first $100,000 of net proceeds (i.e., gross proceeds net of out-of-pocket
expenses incurred in effecting the sale or other disposition) received during
any one calendar year from the sale or other disposition of equipment, furniture
and fixtures of the Borrower and its Subsidiaries, taken together, which are
worn out, obsolete or, in the good faith judgment of the Borrower or such
Subsidiary, no longer desirable to the efficient conduct of its business as then
conducted, (iii) no prepayment shall be required with respect to proceeds
received from the sale, damage or destruction of any of the equipment or other
assets subject to Liens permitted by Section 8.12 

                                      -20-
<PAGE>   27

hereof if and to the extent such proceeds are applied to reduce the indebtedness
secured by such Liens and (iv) so long as no Default or Event of Default has
occurred or is continuing the Borrower or such Subsidiary, as the case may be,
may retain the proceeds derived from the sale, damage or destruction of
fixtures, furniture and equipment if and to the extent that the Borrower or such
Subsidiary establishes to the reasonable satisfaction of the Agent that the
equipment sold, damaged, or destroyed has been replaced (or repaired in the case
of damaged property) with fixtures, furniture or equipment of at least equal
value and utility to that replaced (before any such damage or destruction) which
is subject to a first lien in favor of the Agent for the benefit of the Lenders.
Nothing herein contained shall in any manner impair or otherwise affect the
prohibitions against the sale or other disposition of Collateral contained
herein and in the Collateral Documents.

           (d) Application. Each such prepayment required by this Section 3.3
shall, subject to Section 3.3(e) hereof, be applied to the Term Notes ratably in
accordance with the unpaid principal balances thereof, with the amount allocable
to each class of Term Notes to be applied ratably in reduction of all the
remaining installments of such class of Term Notes.

           (e) Waiver. Notwithstanding anything to the contrary contained in
this Section 3.3 or elsewhere in this Agreement, any Lender with a share of an
outstanding Term B Loan shall have the option to waive any mandatory prepayment
of such Term B Loan pursuant to this Section 3.3 (each such prepayment a
"Waiveable Mandatory Term B Loan Prepayment") upon the terms and provisions set
forth in this Section 3.3(e). In the event any such Lender desires to waive such
Lender's right to receive any such Waiveable Mandatory Term B Loan Prepayment in
whole or in part, such Lender shall so advise the Agent no later than the date
on which such prepayment is to occur, which notice shall also include the amount
such Lender desires to receive in respect of such prepayment. If any such Lender
does not provide such notice, it will be deemed to have accepted 100% of the
total amount. In the event that any such Lender waives all or any part of such
right to receive any such Waiveable Mandatory Term B Loan Prepayment, the Agent
shall apply 100% of the amount so waived by such Lender to the Term A Loan in
accordance with the relevant clause of this Section 3.3, provided that no such
waiver request shall be honored following the prepayment in full of the Term A
Loans.

           Section 3.4. Terminations of Revolving Credit Commitments. The
Borrower shall have the right as of the close of any calendar quarter, upon five
(5) Business Days' prior notice to the Agent (which shall promptly notify the
Lenders), to ratably terminate the Revolving Credit Commitments without premium
or penalty and in whole or in part (but if in part, then in an amount not less
than $5,000,000 or such greater amount which is an integral multiple of
$100,000), provided that the Revolving Credit Commitments may not be reduced to
an amount less than the aggregate principal amount of the Revolving Loans, Swing
Loans and L/C Obligations then outstanding. Any termination of the Revolving
Credit Commitments pursuant 

                                      -21-
<PAGE>   28

to this Section may not be reinstated. Any reduction of the Revolving Credit
Commitments to a level below the L/C Commitment shall effect a concurrent
reduction in the L/C Commitment so as to equal the total Revolving Credit
Commitments after giving effect to such reduction. Each reduction of the
Revolving Credit Commitments shall concurrently reduce the Swing Line Commitment
by the same percentage as such reduction in the Revolving Credit Commitments.

           Section 3.5. Place and Application of Payments. All payments of
principal, interest, fees and all other amounts payable hereunder shall be made
to the Agent at its office at 111 West Monroe Street, Chicago, Illinois (or at
such other place as the Agent may specify) on the date any such payment is due
and payable. All such payments shall be made in lawful money of the United
States of America, in immediately available funds at the place of payment,
without setoff or counterclaim and without reduction for, and free from, any and
all present or future taxes, levies, imposts, duties, fees, charges, deductions,
withholdings, restrictions or conditions of any nature imposed by any government
or any political subdivision or taxing authority thereof (but excluding any
taxes imposed on or measured by the net income of the Lender). Payments received
by the Agent after 11:00 a.m. (Chicago time) shall be deemed received as of the
opening of business on the next Business Day. Except as herein provided, all
payments shall be received by the Agent for the ratable account of the Lenders
and shall be promptly distributed by the Agent ratably to the Lenders. Unless
the Borrower otherwise directs or this Agreement otherwise requires, principal
payments on any particular class of Notes shall be first applied to the Domestic
Rate Portion of such Notes until payment in full thereof, with any balance
applied to the LIBOR Portions of such Notes in the order in which their Interest
Periods expire. Any amount paid or prepaid on the Revolving Credit Notes or
Swing Line Note may, subject to all of the terms and conditions hereof, be
borrowed, repaid and borrowed again. No amount paid or prepaid on the Term Notes
may be reborrowed.

           Anything contained herein to the contrary notwithstanding, all
payments and collections received in respect of the Loans and other Obligations
or the Hedging Liability by the Agent or any of the Lenders after the occurrence
of an Event of Default shall be remitted to the Agent and distributed as
follows:

                   (a) first, to the payment of any outstanding costs and
           expenses incurred by the Agent in protecting, preserving or enforcing
           rights under this Agreement and the other Loan Documents and in any
           event including all costs and expenses of a character which the
           Borrower has agreed to pay under Section 12.4 hereof (such funds to
           be retained by the Agent for its own account unless it has previously
           been reimbursed for such costs and expenses by the Lenders, in which
           event such amounts shall be remitted to the Lenders to reimburse them
           for payments theretofore made to the Agent);

                                      -22-
<PAGE>   29

                   (b) second, to the payment of any outstanding interest or
           other fees or indemnification amounts due under the Loan Documents
           other than for principal of the Loans and L/C Obligations, ratably as
           among the Agent and the Lenders in accord with the amount of such
           interest and other fees or Obligations owing each;

                   (c) third, to the payment of the principal of the Swing
           Loans;

                   (d) fourth, to the payment of the principal of the other
           Loans and any liabilities in respect of Reimbursement Obligations and
           to the Agent to be held as collateral security for any undrawn
           Letters of Credit (until the Agent is holding an amount of cash equal
           to the then outstanding amount of all such Letters of Credit), the
           aggregate amount paid to or held as collateral security for the
           Lenders to be allocated pro rata as among the Lenders in accord with
           the then respective aggregate unpaid principal balances of such Loans
           and the L/C Obligations;

                   (e) fifth, to the Agent, the Lenders ratably in accord with
           the amounts of other Obligations and the Hedging Liability owing to
           each of them (including their Affiliates in the case of Hedging
           Liability) unless and until all such Obligations and the Hedging
           Liability have been fully paid and satisfied; and

                   (f) sixth, to the Borrower or to whoever the Agent reasonably
           determines to be lawfully entitled thereto.

           Section 3.6. Notations and Requests. All Loans made by a Lender
against a Note, the status of all amounts evidenced by a Note (if relevant) as
constituting part of the Domestic Rate Portion or a LIBOR Portion, and the rates
of interest and Interest Periods applicable to such Portions shall be recorded
by such Lender on its books and records or, at its option in any instance,
endorsed on a schedule to its Note and the unpaid principal balance and status,
rates and Interest Periods so recorded or endorsed by such Lender shall be prima
facie evidence in any court or other proceeding brought to enforce its Note of
the principal amount remaining unpaid thereon, the status of the Loans evidenced
thereby and the interest rates and Interest Periods applicable thereto; provided
that the failure of a Lender to record any of the foregoing shall not limit or
otherwise affect the obligation of the Borrower to repay the principal amount of
each Note together with accrued interest thereon. Prior to any Lender's
negotiation of a Revolving Credit or Term Note, such Lender shall record on a
schedule thereto the status of all amounts evidenced thereby as constituting
part of the Domestic Rate Portion or LIBOR Portion and the rates of interest and
the Interest Periods applicable thereto.

SECTION 4.    COLLATERAL.

           Section 4.1. Collateral. The payment and performance of the
Obligations and Hedging Liability shall at all times be secured by, among other
things, (a) all of the Borrower's and its Subsidiaries' accounts, chattel paper,
documents, instruments, general intangibles, inventory, equipment and certain
other assets and property of the Borrower and its Subsidiaries, in each case
whether now owned or held or hereafter acquired or arising, pursuant to that
certain Security Agreement from the Borrower and its Subsidiaries dated as of
even date herewith, as the same may be amended, modified or supplemented from
time to time (the "Security Agreement"), (b) all of the capital stock of the
Subsidiaries and certain other assets and property of the Borrower and its
Subsidiaries, in each case whether now owned or held or hereafter acquired or
arising, pursuant to that certain Pledge Agreement from the Borrower dated as of
even date herewith, as the same may be amended, modified or supplemented from
time to time (the "Pledge Agreement"), and (c) the real estate and related
assets and properties of the Borrower and its Subsidiaries, in each case whether
now owned or held or hereafter acquired or arising, pursuant to mortgages and
trust deeds reasonably acceptable to the Agent as to form and substance
(collectively the "Mortgages" and individually a "Mortgage").

           Section 4.2. Guaranties. Payment of the Notes and the other
Obligations, as well as the Hedging Liability, shall at all times be jointly and
severally guaranteed by each Subsidiary pursuant hereto or pursuant to a
Guaranty issued by such Subsidiary. In the event any Subsidiary is hereafter
acquired or formed, the Borrower shall also cause such Subsidiary to execute
such Collateral Documents (having terms and conditions substantially similar to
those executed by the Borrower and its Subsidiaries in connection with the
initial Loans under this Agreement) as the Agent may then require granting the
Agent for the benefit of the Lenders a security interest in and lien on the
assets of such Subsidiary as collateral security for the Notes and the other
Obligations, as well as the Hedging Liability, together with such other
instruments, documents, certificates and opinions required by the Agent in
connection therewith.

           Section 4.3. Further Assurances. The Borrower covenants and agrees
that it shall, and shall cause each Subsidiary to, comply with all terms and
conditions of each of the Collateral Documents and that the Borrower shall, and
shall cause each Subsidiary to, at any time and from time to time as requested
by the Agent, execute and deliver such further instruments and do such other
acts as the Agent or the Required Lenders may deem necessary or desirable to
provide for or protect or perfect the Lien of the Agent in the Collateral.

provided, however, that all of the foregoing is subject to the following:

                   (i) the initial Applicable Margin in effect through the first
           Margin Determination Date shall be the Applicable Margin for Level V
           Status;

                   (ii) on or before the date that is ten (10) Business Days
           after the date on which the Borrower has delivered a Compliance
           Certificate to the Agent for a given quarterly accounting period of
           the Borrower (commencing with the quarterly accounting period ending
           on or about December 31, 1998) pursuant to Section 8.5 hereof (such
           date that is ten (10) Business Days after the date on which the
           Company delivered a Compliance Certificate to the Agent being herein
           referred to as the "Margin Determination Date"), the Agent shall

           accounting period, and shall promptly notify the Borrower and the
           Lenders of such determination and of any change in the Applicable
           Margin resulting therefrom. Any such change in the Applicable Margin
           shall be effective as of such Margin Determination Date, with such
           new Applicable Margin to continue in effect until the next Margin
           Determination Date. If the Borrower has not delivered a Compliance
           Certificate by the date such Compliance Certificate is required to be
           delivered under Section 8.5 hereof, until a Compliance Certificate is
           delivered before the next Margin Determination Date, the Applicable
           Margin shall be the Applicable Margin for Level V Status. If the
           Borrower subsequently delivers a Compliance Certificate before the
           next Margin Determination Date, the Applicable Margin established by
           such Compliance Certificate shall take effect from the date of
           delivery until the next Margin Determination Date; and

                   (iii) if and so long as any Event of Default has occurred and
           is continuing hereunder, notwithstanding anything herein to the
           contrary, the Applicable Margin shall be the Applicable Margin for

Nassau, Bahamas.

           "Capital Expenditures" means for any period capital expenditures of

SECTION 6.    REPRESENTATIONS AND WARRANTIES.

           The Borrower represents and warrants to the Lenders as follows:

           Section 6.1. Organization and Qualification. The Borrower is duly
organized, validly existing and in good standing as a corporation under the laws
of the State of Georgia, and has full and adequate corporate power to own its
Property and carry on its business as now conducted. The Borrower is duly
licensed or qualified and in good standing in each jurisdiction in which the
nature of the business conducted by it or the nature of the Property owned or
leased by it requires such licensing or qualifying unless and to the extent that
the failure to be so licensed or qualified or to be in such good standing would
not have any material adverse effect on the financial condition, Properties,
business, or operations of the Borrower or in its ability to perform or the
Agent's ability to enforce performance of the Borrower's obligations under the
Loan Documents. The Borrower has full right and authority to enter into this
Agreement, to obtain the credit herein provided for, to issue its Notes in
evidence of the borrowings herein provided for, to execute and deliver each Loan
Document delivered by it, and to perform each and all of the matters and things
therein provided for; and the Loan Documents do not, nor does the performance or
observance by the Borrower of any of the matters and things therein provided
for, contravene or constitute a default under any provision of law or any
judgment, injunction, order or decree binding upon the Borrower or any charter
or by-law provision of the Borrower or any covenant, indenture or agreement of
or affecting the Borrower or any of its respective Properties, or result in the
creation or imposition of any Lien on any Property of the Borrower.

           Section 6.2. Subsidiaries. Each Subsidiary is duly organized, validly
existing and in good standing under the laws of the jurisdiction in which it is
incorporated or organized, as the case may be, has full and adequate power to
own its Property and carry on its business as now conducted, and is duly
licensed or qualified and in good standing in each jurisdiction in which the
nature of the business conducted by it or the nature of the Property owned or
leased by it requires such licensing or qualifying unless and to the extent that
the failure to be so licensed or qualified or to be in such good standing would
not have any material adverse effect on the financial condition, Properties,
business or operations of the Borrower and its Subsidiaries taken as a whole or
in its ability to perform or the Agent's ability to enforce performance of the
Borrower's obligations under the Loan Documents. Each Subsidiary has full right,
power and authority to execute and deliver each Loan Document delivered by it
and to observe and perform each and all of the matters and things therein
provided for, and the Loan Documents do not, nor will the performance or
observance by any Subsidiary of any of the matters and things therein provided
for, contravene any provision of law or any charter or by-law provision of any
Subsidiary or any covenant, indenture or agreement of or affecting the Borrower
or any Subsidiary or any of their respective Properties or require any
governmental approval or consent. Schedule 6.2 hereto identifies each
Subsidiary, the jurisdiction of its incorporation or 

                                      -41-
<PAGE>   48

organization, as the case may be, the percentage of issued and outstanding
shares of each class of its capital stock or other equity interests owned by the
Borrower and the Subsidiaries and, if such percentage is not 100% (excluding
directors' qualifying shares as required by law), a description of each class of
its authorized capital stock and other equity interests and the number of shares
of each class issued and outstanding. All of the outstanding shares of capital
stock and other equity interests of each Subsidiary are validly issued and
outstanding and fully paid and nonassessable and all such shares and other
equity interests indicated on Schedule 6.2 as owned by the Borrower or a
Subsidiary are owned, beneficially and of record, by the Borrower or such
Subsidiary free and clear of all Liens. There are no outstanding commitments or
other obligations of any Subsidiary to issue, and no options, warrants or other
rights of any Person to acquire, any shares of any class of capital stock or
other equity interests of any Subsidiary.

           Section 6.3. Margin Stock. Neither the Borrower nor any of its
Subsidiaries is engaged in the business of extending credit for the purpose of
purchasing or carrying margin stock (within the meaning of Regulation U of the
Board of Governors of the Federal Reserve System), and no part of the proceeds
of any Loan or Letter of Credit issued hereunder will be used to purchase or
carry any such margin stock or to extend credit to others for the purpose of
purchasing or carrying any such margin stock.

           Section 6.4. Financial Reports. The consolidated balance sheet of the
Borrower and its Subsidiaries as at June 30, 1997 and the related consolidated
statements of income, retained earnings and cash flows of the Borrower and its
Subsidiaries for the fiscal year then ended, and accompanying notes thereto,
which financial statements are accompanied by the audit report of Clifton
Gunderson L.L.C., independent public accountants, and the unaudited interim
consolidated balance sheet of the Borrower and its Subsidiaries as at March 31,
1998, and the related consolidated statements of income, retained earnings and
cash flows of the Borrower and its Subsidiaries for the three (3) months then
ended, heretofore furnished to the Lenders, fairly present the consolidated
financial condition of the Borrower and its Subsidiaries as at said dates and
the consolidated results of their operations and cash flows for the periods then
ended in conformity with GAAP applied on a consistent basis. Neither the
Borrower nor any of its respective Subsidiaries has contingent liabilities which
are material to it other than as indicated on such financial statements or, with
respect to future periods, on the financial statements furnished pursuant to
Section 8.5 hereof. Since March 31, 1998, or if later, the date as of which were
prepared the most recent financial statements for the Borrower furnished
pursuant to Section 8.5(a) or (b) hereof, there has been no material adverse
change in the condition (financial or otherwise) or business prospects of the
Borrower and its Subsidiaries taken as a whole.

           Section 6.5. Full Disclosure. The statements and information
furnished to the Agent and the Lenders in connection with the negotiation of
this Agreement and the commitments by the Lenders to provide all or part of the
financing contemplated hereby do not contain any untrue 

                                      -42-
<PAGE>   49

statements of a material fact or omit a material fact necessary to make the
material statements contained therein or herein not misleading, the Lenders
acknowledging that as to any projections furnished to any Lender and the
Borrower only represent that the same were prepared on the basis of information
and estimates the Borrower believed to be reasonable.

             Section 6.6. Good Title. The Borrower and its respective
Subsidiaries have good and defensible title to their respective material assets
as reflected on the most recent consolidated balance sheet of the Borrower and
its Subsidiaries furnished to the Lenders (except for sales of assets by the
Borrower and such Subsidiaries in the ordinary course of their respective
businesses), subject to no Liens other than such thereof as are permitted by
Section 8.12 hereof.

             Section 6.7. Litigation and Other Controversies. There is no
litigation or governmental proceeding or labor controversy pending, nor to the
knowledge of the Borrower threatened, against the Borrower or any of its
Subsidiaries which if adversely determined would result in any material adverse
change in the financial condition, Properties, business or operations of the
Borrower and its Subsidiaries taken as a whole.

             Section 6.8. Taxes. All tax returns with respect to any income tax
or other material tax required to be filed by the Borrower or any Subsidiary in
any jurisdiction have, in fact, been filed, and all taxes, assessments, fees and
other governmental charges upon the Borrower or any Subsidiary or upon any of
their respective Properties, income or franchises, which are shown to be due and
payable in such returns, have been paid. The Borrower does not know of any
proposed additional tax assessment against the Borrower or any Subsidiary which
if paid (taking into consideration any cash segregated for such purpose) would
result in any material adverse change in the financial condition, Properties,
business or operations of the Borrower and its Subsidiaries taken as a whole.
Adequate provisions in accordance with GAAP for taxes on the books of the
Borrower and each Subsidiary have been made, or (to the extent such provisions
have not been made) adequate cash reserves for such taxes have been segregated,
in each case for all open years, and for its current fiscal period.

             Section 6.9. Approvals. No authorization, consent, license,
exemption, filing or registration with any court or governmental department,
agency or instrumentality, nor any approval or consent of the stockholders of
the Borrower or any other Person, is or will be necessary to the valid
execution, delivery or performance by the Borrower of this Agreement, the
Applications or the Notes.

            Section 6.10. Affiliate Transactions. Neither the Borrower nor any
of its Subsidiaries is a party to any contracts or agreements with any of its
Affiliates (other than with Wholly Owned Subsidiaries) on terms and conditions
which are less favorable to the Borrower or such 

                                      -43-
<PAGE>   50

Subsidiary than would be usual and customary in similar contracts or agreements
between Persons not affiliated with each other.

           Section 6.11. Investment Company; Public Utility Holding Company.
Neither the Borrower nor any of its Subsidiaries is an "investment company" or a
company "controlled" by an "investment company" within the meaning of the
Investment Company Act of 1940, as amended, or a "public utility holding
company" within the meaning of the Public Utility Holding Company Act of 1935,
as amended.

           Section 6.12. ERISA. The Borrower and each other member of its
Controlled Group has fulfilled its obligations under the minimum funding
standards of and is in compliance in all material respects with ERISA and the
Code to the extent applicable to it and has not incurred any liability to the
PBGC or a Plan under Title IV of ERISA other than a liability to the PBGC for
premiums under Section 4007 of ERISA. Neither the Borrower nor any Subsidiary
has any contingent liabilities with respect to any post-retirement benefits
under a Welfare Plan, other than liability for continuation coverage described
in article 6 of Title I of ERISA.

           Section 6.13. Compliance with Laws. The Borrower and its Subsidiaries
are in compliance with the requirements of all federal, state and local laws,
rules and regulations applicable to or pertaining to the Properties or business
operations of the Borrower or any such Subsidiary (including, without
limitation, the Occupational Safety and Health Act of 1970, the Americans with
Disabilities Act of 1990, and laws and regulations establishing quality criteria
and standards for air, water, land and toxic or hazardous wastes or substances),
non-compliance with which would reasonably be expected to have a material
adverse effect on the financial condition, Properties, business or operations of
the Borrower and its Subsidiaries taken as a whole. Neither the Borrower nor any
of its Subsidiaries has received notice to the effect that its operations are
not in compliance with any of the requirements of applicable federal, state or
local environmental, health and safety statutes and regulations or are the
subject of any governmental investigation evaluating whether any remedial action
is needed to respond to a release of any toxic or hazardous waste or substance
into the environment, which non-compliance or remedial action would reasonably
be expected to have a material adverse effect on the financial condition,
Properties, business or operations of the Borrower and its Subsidiaries taken as
a whole.

           Section 6.14. Other Agreements. Neither the Borrower nor any of its
Subsidiaries is in default under the terms of any covenant, indenture or
agreement of or affecting the Borrower or any such Subsidiary or any of their
Properties, which default would have a material adverse effect on the financial
condition, Properties, business or operations of the Borrower and its
Subsidiaries taken as a whole.

proceeding in equity or at law); and the Mid-Central Purchase Agreement does
not, nor does the observance or performance by the Borrower or, to the best of

provision of law or any judgment, injunction, order, or decree binding upon such

such Person or any covenant, indenture, or agreement of or affecting such Person

Borrower, to the best of the Borrower's knowledge, such shareholders of the
Mid-Central Purchase Agreement or of any other instrument or document executed
and delivered in connection therewith, except for such thereof that have
heretofore been obtained and remain in full force and effect. Neither the

Mid-Central are in default in any of their respective obligations under the
Mid-Central Purchase Agreement.

                                      -45-
<PAGE>   52

the best of Morton South Carolina's knowledge, the Acquiree and the SMP Purchase
Agreement constitutes the valid and binding obligation of Morton South Carolina
and to the best of Morton South Carolina's knowledge, the Acquiree, enforceable
against each of them in accordance with its terms, except as enforceability may
be limited by bankruptcy, insolvency, fraudulent conveyance or similar laws
affecting creditors' rights generally and general principles of equity
(regardless of whether the application of such principles is considered in a
proceeding in equity or at law); and the SMP Purchase Agreement does not, nor
does the observance or performance by Morton South Carolina or, to the best of
Morton South Carolina's knowledge, the Acquiree of any of the matters and things
therein provided for, contravene or constitute a default under any provision of
law or any judgment, injunction, order, or decree binding upon such Person or
any provision of the charter, articles of incorporation, or by-laws of such
Person or any covenant, indenture, or agreement of or affecting such Person or
any of its Property, or result in the creation or imposition of any Lien on any
such Person's Property. No authorization, consent, license, or exemption from,

instrumentality, nor any approval or consent of any other Person, is or will be
necessary to the valid execution, delivery, or performance by Morton South
Carolina, to the best of Morton South Carolina's knowledge, the Acquiree of the
SMP Purchase Agreement or of any other instrument or document executed and
delivered in connection therewith, except for such thereof that have heretofore
been obtained and remain in full force and effect. Neither Morton South Carolina
nor, to the best of Morton South Carolina's knowledge, any Acquiree are in
default in any of their respective obligations under the SMP Purchase Agreement.

Borrower will not (a) declare or pay any dividends on or make any other
distributions in respect of any class or series of its capital stock or (b)
directly or indirectly purchase, redeem or otherwise acquire or retire any of

         in the case of such a merger or consolidation involving a Guarantor,
         the net worth of the continuing or surviving corporation shall not be
         less than the net worth of such Guarantor immediately prior to such
         merger or consolidation;

                   (b) any Subsidiary may in the ordinary course of its business
         sell, lease or otherwise dispose of all or any substantial part of its

         the purpose of changing the Borrower's state of incorporation to
         Delaware, with such Wholly Owned Subsidiary surviving such merger,
         provided that:

                            (i) at the time of such merger, no Default or Event
                  of Default shall occur or be continuing;

                                      -58-
<PAGE>   65

                            (ii) such Wholly Owned Subsidiary shall have
                  acknowledged in writing (in form and substance reasonably
                  satisfactory to the Agent and Required Lenders) its assumption
                  of all the Borrower's obligations under the Loan Documents to
                  the same extent, with the same force and effect, as if such
                  Wholly Owned Subsidiary were originally the Borrower
                  identified and defined therein;

                            (iii) the Agent shall have received an opinion of
                  counsel of the Borrower, and such other assurances that the
                  Agent or Required Lenders shall reasonably require, to confirm
                  that such merger has been effected in accordance with all
                  applicable laws and that the foregoing conditions set forth in
                  this subsection (c) have been satisfied; and

                            (iv) such merger shall have no adverse effect on the
                  financial condition Properties, business or operations the
                  Borrower or any Subsidiary or on the ability of any Subsidiary

                  the obligations of any of them under the Loan Documents.

other disposition in any fiscal year of five percent (5%) or more of the
Properties of the Borrower and its Subsidiaries taken as a whole.

assets located primarily in the United States used or useful in a business

Subsidiary (or Acquisitions of the capital stock of a corporation engaged
primarily in such a business if (a) the corporation's primary operations are in
the United States and (b) immediately after giving effect to such Acquisition,
the corporation so acquired becomes a Subsidiary) if and only if: (i) the
Borrower has, prior to committing to the acquisition, notified the Lenders
thereof and demonstrated to the satisfaction of the Lenders that no Default or
Event of Default shall occur or be continuing at the time of or after giving
effect to the Acquisition in question, (ii) the board of directors or other
governing body of such Person whose Property, or voting stock or other interests
in which, are being so acquired has approved the terms of such Acquisition,

for such Acquisition (and in any event (1) including as such consideration, any
Indebtedness assumed or incurred as a result of such Acquisition, and (2)
excluding as such consideration, any equity securities issued by the Borrower as
consideration for such Acquisition), when taken together with the aggregate
amount expended as consideration 

                                      -59-
<PAGE>   66

(including Indebtedness and excluding equity securities as aforesaid) for all

date hereof) during the then twelve most recently completed calendar months does

Acquisition that (x) the Cash Flow Leverage Ratio (such pro forma calculation of
the Cash Flow Leverage Ratio to be made on the basis of the information
contained in the then most recent Compliance Certificate required to be
submitted to each Lender with the following adjustments: (i) Total Funded Debt
shall include all indebtedness incurred directly or indirectly to finance such
Acquisition and (ii) EBITDA shall be computed as if such Acquisition had
occurred at the commencement of the four-quarter period with reference to which
the Cash Flow Leverage Ratio is being calculated) is less than 3.0 to 1.0 and
(y) the Borrower will continue to comply through the term of this Agreement with

reimburse the Agent and Lenders for their reasonable out-of-pocket costs of
conducting due diligence to verify such demonstration), (vii) at least twenty
(20) Business Days in advance of the closing of such Acquisition, the Borrower

reasonably request and (viii) after giving effect to such Acquisition, the
Revolving Loans and L/C Obligations are at least $5,000,000 below the Revolving
Credit Commitments then in effect. Capital Expenditures for Property in
compliance with Section 8.10 hereof shall not be considered Acquisitions subject
to this Section.

         Section 8.18. Maintenance of Subsidiaries. The Borrower will not
assign, sell or transfer, or permit any of its Subsidiaries to issue, assign,
sell or transfer, any shares of capital stock of a Subsidiary, provided that the
foregoing shall not operate to prevent the issuance, sale and transfer to any

qualifying, and to the extent legally necessary to qualify, such person as a
director of such Subsidiary.

         Section 8.19. Formation of Subsidiaries. In the event any Subsidiary is

such new Subsidiary and (y) cause such newly-formed or acquired Subsidiary to
execute a Guaranty and execute such Collateral Documents to the extent required
by Section 4 hereof (on terms substantially similar to those executed in
connection with this Agreement) as the Agent may then require granting the Agent
for the benefit of the Lenders a security interest in and lien on the personal
property of such 

                                      -60-
<PAGE>   67

Subsidiary as collateral security for the Notes and the other Obligations, as
well as the Hedging Liability, together with documentation (including a legal
opinion) similar to that described in Section 7.2 hereof relating to the
authorization for, execution and delivery of, and validity of such Subsidiary's
obligations as a Guarantor hereunder and otherwise under its Loan Documents in
form and substance satisfactory to the Agent and such other instruments,
documents, certificates and opinions as are required by the Agent in connection
therewith.

         Section 8.20. ERISA. The Borrower will, and will cause each of its
Subsidiaries to, promptly pay and discharge all obligations and liabilities
arising under ERISA of a character which if unpaid or unperformed might result
in the imposition of a Lien against any material portion of its Properties. The
Borrower will, and will cause each of its Subsidiaries to, promptly notify the
Lenders of (i) the occurrence of any reportable event (as defined in ERISA) with
respect to a Plan, (ii) receipt of any notice from the PBGC of its intention to
seek termination of any Plan or appointment of a trustee therefor, (iii) its
intention to terminate or withdraw from any Plan, and (iv) the occurrence of any
event with respect to any Plan which would result in the incurrence by the
Borrower or any of its Subsidiaries of any material liability, fine or penalty,
or any material increase in the contingent liability of the Borrower or any such
Subsidiary with respect to any post-retirement Welfare Plan benefit.

         Section 8.21. Compliance with Laws. The Borrower will, and will cause
each of its Subsidiaries to, comply in all respects with the requirements of all
federal, state and local laws, rules, regulations, ordinances and orders
applicable to or pertaining to the Properties or business operations of the
Borrower or any such Subsidiary, non-compliance with which could have a material
adverse effect on the financial condition, Properties, business or operations of
the Borrower and its Subsidiaries taken as a whole or would reasonably be
expected to result in a Lien upon any of their Property.

         Section 8.22. Burdensome Contracts With Affiliates. The Borrower will
not, and will not permit any of its Subsidiaries to, enter into any contract,
agreement or business arrangement with any of its Affiliates (other than with
Wholly Owned Subsidiaries) on terms and conditions which are less favorable to
the Borrower or such Subsidiary than would be usual and customary in similar
contracts, agreements or business arrangements between Persons not affiliated
with each other.

         Section 8.23. Changes in Fiscal Year. Except to change (with notice to
the Lenders) its fiscal year to correspond with the calendar year, neither the
Borrower nor any of its Subsidiaries will change its fiscal year from its
present basis without the prior written consent of the Required Lenders.

                                      -61-
<PAGE>   68

         Section 8.24. Change in the Nature of Business. The Borrower will not,
and will not permit any of its Subsidiaries to, engage in any business or
activity if as a result the general nature of the business of the Borrower or
any such Subsidiary would be changed in any material respect from the general
nature of the business engaged in by the Borrower or such Subsidiary on the date
of this Agreement.

         Section 8.25. Use of Loan Proceeds. The Borrower will use the Revolving

         Section 8.26. Interest Rate Protection. On or before the date hereof,
the Borrower will hedge its interest rate risk on 50% of the principal amount
outstanding on the Term Loans, through the use of one or more interest rate
swaps, interest rate caps, interest rate collars or other recognized interest
rate hedging arrangements for a minimum of three years (collectively, "Hedging
Arrangements"), with all of the foregoing to effectively limit the amount of
interest that the Borrower must pay on notional amounts of not less than such
portion of the Term Loans to not more than a rate acceptable to the Agent in its
discretion for a period ending no earlier than June 1, 2001 and to be with the
Lenders, their respective Affiliates or with other parties reasonably acceptable
to the Required Lenders. If the Borrower enters into any Hedging Arrangements
with any Lender, the Borrower's obligations to such Lender in connection with
such Hedging Arrangements do not constitute usage of the Commitments of such
Lender.

<PAGE>   71

                   (b) declare the principal of and the accrued interest on the
         Notes to be forthwith due and payable and thereupon the Notes,
         including both principal and interest and all fees, charges and other
         amounts payable hereunder, shall be and become immediately due and
         payable without further demand, presentment, protest or notice of any
         kind.

         Section 9.3. When any Event of Default described in clauses (m) or (n)
of Section 9.1 has occurred and is continuing, then the Notes, including both
principal and interest, and all fees, charges and other amounts payable
hereunder, shall immediately become due and payable without presentment, demand,
protest or notice of any kind, and the obligations of the Lenders to extend
further credit pursuant to any of the terms hereof shall immediately terminate.

         Section 9.4. When any Event of Default, other than an Event of Default
described in subsections (m) or (n) of Section 9.1, has occurred and is
continuing, the relevant Borrower shall, upon demand of the Agent (which demand
shall be made upon the request of the Required Lenders), and when any Event of
Default described in subsections (m) or (n) of Section 9.1 has occurred the
Borrower shall, without notice or demand from the Agent, immediately pay to the
Agent the full outstanding amount of each Letter of Credit (such amount to be
held as cash collateral for the Borrower's obligations in respect of the Letters
of Credit), the Borrower agreeing to immediately make each such payment and
acknowledging and agreeing the Agent and the Lenders would not have an adequate
remedy at law for failure of the Borrower to honor any such demand and that the
Agent shall have the right to require the Borrower to specifically perform such
undertaking whether or not any draws had been made under any such Letter of
Credit.

SECTION 10.   THE AGENT.

         Section 10.1. Appointment and Authorization. Each Lender hereby
appoints and authorizes the Agent to take such action as agent on its behalf and
to exercise such powers hereunder and under the Guaranties and the Applications
as are designated to the Agent by the terms hereof and thereof together with
such powers as are reasonably incidental thereto. The Lenders expressly agree
that the Agent is not acting as a fiduciary of the Lenders in respect of the
Loan Documents, the Borrower or otherwise, and nothing herein or in any of the
other Loan Documents shall result in any duties or obligations on the Agent or
any of the Lenders except as expressly set forth herein. The Agent may resign at
any time by sending twenty (20) days prior written notice to the Borrower and
the Lenders and may be removed by the Required Lenders upon twenty (20) days
prior written notice to the Borrower and the Lenders. In the event of any such
resignation or removal the Required Lenders may appoint a new agent after
consultation with the Borrower, which shall succeed to all the rights, powers
and duties of the Agent hereunder and under the Guaranties and Applications. Any
resigning or removed Agent shall be 

                                      -65-
<PAGE>   72

entitled to the benefit of all the protective provisions hereof with respect to
its acts as an agent hereunder, but no successor Agent shall in any event be
liable or responsible for any actions of its predecessor. If the Agent resigns
or is removed and no successor is appointed, the rights and obligations of such
Agent shall be automatically assumed by the Required Lenders and (i) the
Borrower shall be directed to make all payments due each Lender hereunder
directly to such Lender and (ii) the Agent's rights in the Guaranties and
Applications shall be assigned without representation, recourse or warranty to
the Lenders as their interests may appear.

         Section 10.2. Rights as a Lender. The Agent has and reserves all of the
rights, powers and duties hereunder and under its Notes and the Guaranties and
Applications as any Lender may have and may exercise the same as though it were
not the Agent and the terms "Lender" or "Lenders" as used herein and in all of
such documents shall, unless the context otherwise expressly indicates, include
the Agent in its individual capacity as a Lender.

         Section 10.3. Standard of Care. The Lenders acknowledge that they have
received and approved copies of the Guaranties and such other information and
documents concerning the transactions contemplated and financed hereby as they
have requested to receive and/or review. The Agent makes no representations or
warranties of any kind or character to the Lenders with respect to the validity,
enforceability, genuineness, perfection, value, worth or collectibility hereof
or of the Notes or the Guaranties or of any other documents called for hereby or
thereby. Neither the Agent nor any director, officer, employee, agent or
representative thereof shall in any event be liable for any clerical errors or
errors in judgment, inadvertence or oversight, or for action taken or omitted to
be taken by it or them hereunder or under the Guaranties or Applications or in
connection herewith or therewith except for its or their own gross negligence or
willful misconduct. The Agent shall incur no liability under or in respect of
this Agreement or the Guaranties or Applications by acting upon any notice,
certificate, warranty, instruction or statement (oral or written) of anyone
(including anyone in good faith believed by it to be authorized to act on behalf
of the Borrower), unless it has actual knowledge of the untruthfulness of same.
The Agent may execute any of its duties hereunder by or through employees,
agents, and attorneys-in-fact and shall not be answerable to the Lenders for the
default or misconduct of any such agents or attorneys-in-fact selected with
reasonable care except for the gross negligence or willful misconduct of its
employees. The Agent shall be entitled to advice of counsel concerning all
matters pertaining to the agencies hereby created and its duties hereunder, and
shall incur no liability to anyone and be fully protected in acting upon the
advice of such counsel. The Agent shall be entitled to assume that no Default or
Event of Default exists unless notified to the contrary by a Lender. The Agent
shall in all events be fully protected in acting or failing to act in accord
with the instructions of the Required Lenders. The Agent shall in all cases be
fully justified in failing or refusing to act hereunder unless it shall be
indemnified to its satisfaction by the Lenders against any and all liability and
expense which may be incurred by the Agent by reason of taking or continuing to
take any such action. The Agent may treat the owner of any 

                                      -66-
<PAGE>   73

Note as the holder thereof until written notice of transfer shall have been
filed with the Agent signed by such owner in form satisfactory to the Agent.
Each Lender acknowledges that it has independently and without reliance on the
Agent or any other Lender and based upon such information, investigations and
inquiries as it deems appropriate made its own credit analysis and decision to
extend credit to the Borrower. It shall be the responsibility of each Lender to
keep itself informed as to the creditworthiness of the Borrower and the Agent
shall have no liability to any Lender with respect thereto.

         Section 10.4. Costs and Expenses. Each Lender agrees to reimburse the
Agent for all costs and expenses suffered or incurred by the Agent in performing
its duties hereunder and under the Guaranties and Applications, or in the
exercise of any right or power imposed or conferred upon the Agent hereby or
thereby, to the extent that the Agent is not promptly reimbursed for same by the
Borrower, all such costs and expenses to be borne by the Lenders ratably in
accordance with the amounts of their respective Commitments. If any Lender fails
to reimburse the Agent for such Lender's share of any such costs and expenses,
such costs and expenses shall be paid pro rata by the remaining Lenders, but
without in any manner releasing the defaulting Lender from its liability
hereunder.

         Section 10.5. Indemnity. The Lenders, to the extent not prohibited by
applicable law, shall ratably indemnify and hold the Agent, and its directors,
officers, employees, agents or representatives harmless from and against any
liabilities, losses, costs and expenses suffered or incurred by them hereunder
or under the Guaranties or Applications or in connection with the transactions
contemplated hereby or thereby, regardless of when asserted or arising, except
to the extent they are promptly reimbursed for the same by the relevant Borrower
and except to the extent that any event giving rise to a claim was caused by the
gross negligence or willful misconduct of the party seeking to be indemnified.
If any Lender defaults in its obligations hereunder, its share of the
obligations shall be paid pro rata by the remaining Lenders, but without in any
manner releasing the defaulting Lender from its liability hereunder.

         Section 10.6. Interest Rate Hedging Arrangements. By virtue of a
Lender's execution of this Agreement or an Assignment Agreement, as the case may
be, any Affiliate of such Lender with whom the Borrower has entered into an
agreement creating Hedging Liability shall be deemed a Lender party hereto for
purpose of any reference in a Loan Document to the parties for whom the Agent is
acting, it being understood and agreed that the rights and benefits of such
Affiliate under the Loan Documents consist exclusively of such Affiliate's right
to share in payments and collections out of the Collateral and the Guaranties as
more fully set forth in other provisions hereof.

SECTION 11.   JOINT AND SEVERAL LIABILITY AND GUARANTIES.

         Section 11.1. Joint and Several Liability and Guaranties. To induce the
Lenders to provide the credit described herein and in consideration of benefits
expected to accrue to each Guarantor by reason of the Commitments and for other
good and valuable consideration, receipt of which is hereby acknowledged, each
Subsidiary party hereto and each Subsidiary which executes and delivers a
Guaranty (each such Subsidiary being hereinafter referred to individually as a
"Guarantor" and collectively as the "Guarantors") hereby unconditionally and
irrevocably guarantee jointly and severally to the Agent, the Lenders, their
Affiliates and each other holder of any of the Obligations or Hedging Liability,
(x) the due and punctual payment of all present and future Obligations,
including, but not limited to, the due and punctual payment of principal of and
interest on the Loans and Reimbursement Obligations, as and when the same shall
become due and payable, whether at stated maturity, by acceleration or
otherwise, according to the terms hereof and thereof and (y) the due and
punctual payment of all present and future Hedging Liability as and when the
same shall become due and payable, whether at its stated maturity, by
acceleration or otherwise, according to the terms thereof (the Obligations and
Hedging Liability so guaranteed being hereinafter referred to collectively as
the "Guaranteed Obligations"). In case of failure by the Borrower punctually to
pay any Guaranteed Obligations, each Guarantor hereby unconditionally agrees
jointly and severally to make such payment or to cause such payment to be made
punctually as and when the same shall become due and payable, whether at stated
maturity, by acceleration or otherwise, and as if such payment were made by the
Borrower.

         Section 11.2. Guaranty Unconditional. The obligations of each Guarantor
as a guarantor or joint and several obligor under the Loan Documents, the
instruments or documents governing any Hedging Liability (the loan documents and
such other instruments and documents governing the Hedging Liability being
hereinafter referred to collectively as the "Guaranteed Debt Documents" and
individually as a "Guaranteed Debt Document," including this Section 11, shall
be unconditional and absolute and, without limiting the generality of the
foregoing, shall not be released, discharged or otherwise affected by:

                   (a) any extension, renewal, settlement, compromise, waiver or
         release in respect of any obligation of the Borrower or of any other
         Guarantor under this Agreement or any other Guaranteed Debt Document or
         by operation of law or otherwise;

                   (b) any modification or amendment of or supplement to this
         Agreement or any other Guaranteed Debt Document;

                   (c) any change in the corporate existence, structure or
         ownership of, or any insolvency, bankruptcy, reorganization or other
         similar proceeding affecting, the 

                                      -68-
<PAGE>   75

         Borrower, any other Guarantor, or any of their respective assets, or
         any resulting release or discharge of any obligation of the Borrower or
         of any other Guarantor contained in any Guaranteed Debt Document;

                   (d) the existence of any claim, set-off or other rights which
         the Guarantor may have at any time against the Agent, any Lender or any
         other Person, whether or not arising in connection herewith;

                   (e) any failure to assert, or any assertion of, any claim or
         demand or any exercise of, or failure to exercise, any rights or
         remedies against the Borrower, any other Guarantor or any other Person
         or Property;

                   (f) any application of any sums by whomsoever paid or
         howsoever realized to any obligation of the Borrower, regardless of
         what obligations of the Borrower remain unpaid;

                   (g) any invalidity or unenforceability relating to or against
         the Borrower or any other Guarantor for any reason of this Agreement or
         of any other Guaranteed Debt Document or any provision of applicable
         law or regulation purporting to prohibit the payment by the Borrower or
         any other Guarantor of the principal of or interest on any Note or any
         other amount payable by them under the Guaranteed Debt Documents; or

                   (h) any other act or omission to act or delay of any kind by
         the Agent, any Lender or any other Person or any other circumstance
         whatsoever that might, but for the provisions of this paragraph,
         constitute a legal or equitable discharge of the obligations of the
         Guarantors under the Guaranteed Debt Documents.

         Section 11.3. Discharge Only Upon Payment in Full; Reinstatement in
Certain Circumstances. Each Guarantor's obligations under this Section 11 shall
remain in full force and effect until the Commitments are terminated and the
principal of and interest on the Notes and all other Guaranteed Obligations
shall have been paid in full. If at any time any payment of the principal of or
interest on any Note or any other amount payable by the Borrower under any of
the Guaranteed Debt Documents is rescinded or must be otherwise restored or
returned upon the insolvency, bankruptcy or reorganization of the Borrower or of
any Guarantor, or otherwise, each Guarantor's obligations under this Section 11
with respect to such payment shall be reinstated at such time as though such
payment had become due but had not been made at such time.

<PAGE>   76


         Section 11.4. Waivers.

         (a) General. Each Guarantor irrevocably waives acceptance hereof,
presentment, demand, protest and any notice not provided for herein, as well as
any requirement that at any time any action be taken by the Agent, any Lender or
any other Person against the Borrower, another Guarantor or any other Person.

         (b) Subrogation and Contribution. Each Guarantor hereby agrees not to
exercise or enforce any right of exoneration, contribution, reimbursement,
recourse or subrogation available to such Guarantor against any Person liable
for payment of the Guaranteed Obligations, or as to any security therefor,
unless and until the full amount owing on the Guaranteed Obligations has been
paid and the Commitments have terminated; and the payment by such Guarantor of
any amount pursuant to any of the Guaranteed Debt Documents on account of credit
extended to the Borrower shall not in any way entitle such Guarantor to any
right, title or interest (whether by way of subrogation or otherwise) in and to
any of the Guaranteed Obligations or any proceeds thereof or any security
therefor unless and until the full amount owing on the Guaranteed Obligations
has been paid and the Commitments have terminated.

         Section 11.5. Limit on Recovery. Notwithstanding any other provision
hereof, the right of recovery against each Guarantor under this Section 11 shall
not (to the extent required by or as may be necessary or desirable to ensure the
enforceability against such Guarantor of its obligations hereunder or thereunder
in accordance with the laws of the jurisdiction of its incorporation or where it
carries on business) exceed (x) the amount which would render such Guarantor's
obligations under this Section 11 void or voidable under applicable law,
including without limitation fraudulent conveyance law minus (y) $1.00.

         Section 11.6. Stay of Acceleration. If acceleration of the time for
payment of any amount payable by the Borrower under this Agreement or any other
Loan Document is stayed upon the insolvency, bankruptcy or reorganization of the
Borrower, all such amounts otherwise subject to acceleration under the terms of
this Agreement or the other Guaranteed Debt Documents shall nonetheless be
payable jointly and severally by the Guarantors hereunder forthwith on demand by
the Agent made at the request of the Required Lenders.

         Section 11.7. Benefit to Guarantors. All of the Guarantors are engaged
in related businesses and integrated to such an extent that the financial
strength and flexibility of each Guarantor has a direct impact on the success of
each other Guarantor. Each Guarantor will derive substantial direct and indirect
benefit from the extension of credit hereunder.

         Section 11.8. Guarantor Covenants. Each Guarantor shall take such
action as the Borrower is required by this Agreement to cause such Guarantor to
take, and shall refrain from 

                                      -70-
<PAGE>   77

taking such action as the Borrower is required by this Agreement to prohibit
such Guarantor from taking.


SECTION 12.              MISCELLANEOUS.

         Section 12.1. Holidays. If any payment of principal or interest on any
Note or any fee hereunder shall fall due on a day which is not a Business Day,
principal together with interest at the rate the Note bears for the period prior
to maturity or any fee at the rate such fee accrues shall continue to accrue
from the stated due date thereof to and including the next succeeding Business
Day, on which the same is payable.

         Section 12.2. No Waiver, Cumulative Remedies. No delay or failure on
the part of the Agent or any Lender or on the part of any other holder of any
Note in the exercise of any power or right shall operate as a waiver thereof,
nor as an acquiescence in any default, nor shall any single or partial exercise
of any power or right preclude any other or further exercise thereof, or the
exercise of any other power or right, and the rights and remedies hereunder of
the Agent, each Lender and each other holder of any Note are cumulative to, and
not exclusive of, any rights or remedies which any of them would otherwise have.

         Section 12.3. Waivers, Modifications and Amendments. Any provision
hereof or of the Notes or the Guaranties may be amended, modified, waived or
released and any Default or Event of Default and its consequences may be
rescinded and annulled upon the written consent of the Required Lenders;
provided, however, that without the consent of all Lenders no such amendment,
modification or waiver shall increase the amount or extend the terms of any
Lender's Commitment or increase the L/C Commitment or reduce the interest rate
applicable to or extend the maturity (including any scheduled installment) of
its Notes or reduce the amount of the principal or interest or fees to which
such Lender is entitled hereunder or release any substantial (in value) part of
the collateral security afforded by the Collateral Documents (except in
connection with a sale or other disposition required to be effected by the
provisions hereof or of the Collateral Documents) or release any Guarantor or
change this Section or change the definition of "Required Lenders" or change the
number of Lenders required to take any action hereunder or under the Guaranties.
No amendment, modification or waiver of the Agent's protective provisions shall
be effective without the prior written consent of the Agent.

         Section 12.4. Costs and Expenses. The Borrower agrees to pay on demand
the costs and expenses of the Agent in connection with the negotiation,
preparation, execution and delivery of the Loan Documents and the other
instruments and documents to be delivered hereunder or thereunder or in
connection with the transactions contemplated hereby or thereby or in connection
with any consents hereunder or waivers or amendments hereto or thereto,
including the fees and expenses of Messrs. Chapman and Cutler, counsel for the
Agent, with respect to all 

                                      -71-
<PAGE>   78


of the foregoing (whether or not the transactions contemplated hereby are
consummated), and all costs and expenses (including attorneys' fees), if any,
incurred by the Agent, the Lenders or any other holders of a Note in connection
with a default under or the enforcement of the Loan Documents or any other
instrument or document to be delivered hereunder or thereunder. The Borrower
agrees to pay on demand all costs and expenses for which it is liable in
accordance with the preceding sentence in connection with Letters of Credit
issued for its account. The Borrower agrees to indemnify and save the Lenders
and the Agent harmless from any and all liabilities, losses, costs and expenses
(collectively, "indemnified liabilities") incurred by the Lenders or the Agent
in connection with any action, suit or proceeding brought against the Agent or
any Lender by any Person (but excluding attorneys' fees for litigation solely
between the Lenders to which the Borrower is not a party) which arises out of
the transactions contemplated or financed hereby or out of any action or
inaction by the Agent or any Lender hereunder or thereunder, except for such
thereof as is caused by the gross negligence or willful misconduct of the party
seeking to be indemnified. The Borrower agrees to similarly indemnify and save
the Lenders and the Agent harmless from any and all indemnified liabilities as
relate to Letters of Credit issued for its account. The provisions of this
Section and the protective provisions of Section 2 hereof shall survive payment
of the Notes.

         Section 12.5. Documentary Taxes. The Borrower agrees to pay on demand
any documentary, stamp or similar taxes payable in respect of this Agreement,
the Notes, the Applications, or any Guaranty including interest and penalties,
in the event any such taxes are assessed, irrespective of when such assessment
is made and whether or not any credit is then in use or available hereunder.

         Section 12.6. Survival of Representations. All representations and
warranties made herein or in any other Loan Documents or in certificates given
pursuant hereto or thereto shall survive the execution and delivery of this
Agreement and shall continue in full force and effect with respect to the date
as of which they were made as long as any credit is in use or available
hereunder.

         Section 12.7. Survival of Indemnities. All indemnities and other
provisions relative to reimbursement to the Lenders of amounts sufficient to
protect the yield of the Lenders with respect to the Loans and Letters of
Credit, including, but not limited to, Sections 1.3, 2.7, 2.8 and 2.9 hereof,
shall survive the termination of this Agreement and the payment of the Notes.

         Section 12.8. Notices. Except as otherwise specified herein, all
notices hereunder shall be in writing (including cable or telecopy) and shall be
given to the relevant party at its address or telecopier number set forth below,

purpose.

         Section 12.10. Severability of Provisions. Any provision of this
Agreement which is unenforceable in any jurisdiction shall, as to such
jurisdiction, be ineffective to the extent of such unenforceability without
invalidating the remaining provisions hereof or affecting the validity or
enforceability of such provision in any other jurisdiction. All rights, remedies
and powers provided in this Agreement and the Notes may be exercised only to the
extent that the exercise thereof does not violate any applicable mandatory
provisions of law, and all the provisions of this Agreement and the Notes are
intended to be subject to all applicable mandatory provisions of law which may
be controlling and to be limited to the extent necessary so that they will not
render this Agreement or the Notes invalid or unenforceable.

         Section 12.11. Counterparts. This Agreement may be executed in any
number of counterparts, and by different parties hereto on separate counterpart
signature pages, and all such counterparts taken together shall be deemed to
constitute one and the same instrument.

         Section 12.12. Binding Nature, Governing Law, Etc. This Agreement shall
be binding upon the Borrower and its successors and assigns, and shall inure to

regard to principles of conflicts of laws. The Borrower may not assign its
rights hereunder without the written consent of the Lenders.

         Section 12.13. Entire Understanding. This Agreement, together with the
Notes, constitute the entire understanding of the parties with respect to the
subject matter hereof and any prior agreements, whether written or oral, with
respect thereto are superseded hereby except for prior understandings related to
fees payable to the Agent upon the initial closing of the transactions
contemplated hereby.

         Section 12.14. Participations. Any Lender may, upon the prior written
consent of any Borrower (which consent shall not be unreasonably withheld),
grant participations in its extensions of credit hereunder to any other bank or
other lending institution (a "Participant") provided that (i) no Participant
shall thereby acquire any direct rights under this Agreement, (ii) no Lender
shall agree with a Participant not to exercise any of such Lender's rights
hereunder without the consent of such Participant except for rights which under
the terms hereof may only be exercised by all Lenders and (iii) no sale of a
participation in extensions of credit shall in any manner relieve the selling
Lender of its obligations hereunder.

         Section 12.15. Assignment Agreements. Each Lender may, from time to
time upon at least five (5) Business Days' prior written notice to the Agent,
assign to other commercial lenders part of its rights and obligations under this
Agreement (including without limitation the indebtedness evidenced by any Note
then owned by such assigning Lender, together with an equivalent proportion of
the related Commitment for which such Note was issued) pursuant to written
agreements executed by such assigning Lender, such assignee lender or lenders,
the Borrower and the Agent, which agreements shall specify in each instance the
portion of the indebtedness evidenced by the Notes which is to be assigned to
each such assignee lender and the portion of the Commitments of the assigning
Lender to be assumed by it (the "Assignment Agreements"); provided, however,
that (i) the assignment of a Revolving Credit Note shall cover the same
percentage of such Lender's Revolving Credit Commitment, Revolving Loans and
interests in Letters of Credit; (ii) unless the Agent otherwise consents, the
aggregate amount of the Commitments, Loans and Notes of the assigning Lender
being assigned pursuant to each such assignment (determined as of the effective
date of the relevant Assignment Agreement) shall in no event be less than
$5,000,000 and shall be an integral multiple of $1,000,000; (iii) the Swing
Loans and Swing Line Commitment shall only be assigned (if at all) in total,
(iv) the Agent, each Lender originally party hereto and the Borrower must each
consent (such consent to not be unreasonably withheld by any such party), to
each such assignment to a party which was not an original signatory of this
Agreement (provided no such consent is required from the Borrower (x) for any
assignment to any Lender party hereto, whether an original signatory of this
Agreement or a party hereto by reason of an Assignment Agreement, (y) for any
assignment to any Affiliate of any such Lender and (z) for any such assignment

                                GRANTING CLAUSE V

         All property and rights, if any, which are by the express provisions of
this instrument required to be subjected to the lien hereof and any additional
property and rights that may from time to time hereafter, by installation or
writing of any kind, be subjected to the lien hereof by Mortgagor or by anyone
in Mortgagor's behalf.


                               GRANTING CLAUSE VI

         All rights in and to common areas and access roads on adjacent
properties heretofore or hereafter granted to Mortgagor and any after-acquired
title or reversion in and to the beds of any ways, roads, streets, avenues and
alleys adjoining the property described in Granting Clause I or any part
thereof.

         TO HAVE AND TO HOLD the Mortgaged Premises and the properties, rights
and privileges hereby granted, bargained, sold, conveyed, mortgaged, warranted,
pledged and assigned, and in which a security interest is granted, or intended
so to be, unto Mortgagee, its successors and assigns, forever; provided,
however, that this instrument is upon the express condition that if the
principal of and interest on the Notes shall be paid in full and all other
indebtedness hereby secured shall be fully paid and performed and no Letters of
Credit shall remain outstanding, then this instrument and the estate and rights
hereby granted shall cease, determine and be void and this instrument shall be
released by Mortgagee upon the written request and at the expense of Mortgagor,
otherwise to remain in full force and effect.

         It is expressly understood and agreed that the indebtedness hereby
secured will in no event exceed two hundred percent (200%) of (i) the total face
amount of the Notes and the Letters of Credit plus (ii) the total interest which
may hereafter accrue under the Notes and the Reimbursement Obligations (as
defined in the Credit Agreement) on such face amount plus (iii) any fees, costs
or expenses which may be payable hereunder or under the Credit Agreement.

         Mortgagor hereby covenants and agrees with Mortgagee as follows:

                    1. Payment of the Indebtedness. The indebtedness hereby
         secured will be promptly paid as and when the same becomes due without
         any relief whatever from valuation or appraisement laws of the State of
         Iowa.

                    2. Binding Obligation and Further Assurances. This Mortgage
         and all other documents, instruments and agreements executed in
         connection herewith are valid and binding obligations of Mortgagor,
         enforceable in accordance with their respective terms. 


                                      -6-
<PAGE>   7

         Mortgagor will execute and deliver such further instruments and do such
         further acts as may be necessary or proper to carry out more
         effectively the purpose of this instrument and, without limiting the
         foregoing, to make subject to the lien hereof any property agreed to be
         subjected hereto or covered by the Granting Clauses hereof or intended
         so to be.

                    3. Ownership of the Mortgaged Premises. Mortgagor covenants
         and warrants that it is lawfully seized of and has good and marketable
         fee title to the Mortgaged Premises free and clear of all liens,
         charges and encumbrances whatsoever except those exceptions to title
         listed on Schedule II attached hereto (the "Permitted Exceptions") and
         Mortgagor has good right, full power and authority to convey, transfer
         and mortgage the same to Mortgagee for the uses and purposes set forth
         in this Mortgage; and Mortgagor will warrant and forever defend the
         title to the Mortgaged Premises subject to the Permitted Exceptions
         against all claims and demands whatsoever.

                    4. Possession. Provided no event of default has occurred and
         is continuing hereunder, Mortgagor shall be suffered and permitted to
         remain in full possession, enjoyment and control of the Mortgaged
         Premises, subject always to the observance and performance of the terms
         of this instrument.

                    5. Payment of Taxes. Mortgagor shall pay before any penalty
         attaches, all general taxes and all special taxes, special assessments,
         water, drainage and sewer charges and all other charges of any kind
         whatsoever, ordinary or extraordinary, which may be levied, assessed,
         imposed or charged on or against the Mortgaged Premises or any part
         thereof and which, if unpaid, might by law become a lien or charge upon
         the Mortgaged Premises or any part thereof, and shall, upon written
         request, exhibit to Mortgagee official receipts evidencing such
         payments, except that, unless and until foreclosure, distraint, sale or
         other similar proceedings shall have been commenced, no such charge or
         claim need be paid if being contested (except to the extent any full or
         partial payment shall be required by law), after notice to Mortgagee,
         by appropriate proceedings which shall operate to prevent the
         collection thereof or the sale or forfeiture of the Mortgaged Premises
         or any part thereof to satisfy the same, conducted in good faith and
         with due diligence and if Mortgagor shall have furnished such security,
         if any, as may be required in the proceedings or requested by
         Mortgagee.

                    6. Payment of Taxes on Notes, Letters of Credit, Mortgage or
         Interest of Mortgagee or Secured Creditors. Mortgagor agrees that if
         any tax, assessment or imposition upon this Mortgage or the
         indebtedness hereby secured or the Notes or any of the Letters of
         Credits or the interest of Mortgagee or any Secured Creditor in the
         Mortgaged Premises or upon Mortgagee or any Secured Creditor by reason
         of or as a 


                                      -7-
<PAGE>   8

         holder of any of the foregoing (including, without limitation, excise
         taxes, but excepting therefrom any income tax on interest payments on
         the principal portion of the indebtedness hereby secured imposed by the
         United States or any state) is levied, assessed or charged, then,
         unless all such taxes are paid by Mortgagor to, for or on behalf of
         Mortgagee or any Secured Creditor as they become due and payable (which
         Mortgagor agrees to do upon demand of Mortgagee, to the extent
         permitted by law), or Mortgagee or any Secured Creditor is reimbursed
         for any such sum advanced by Mortgagee, all sums hereby secured shall
         become immediately due and payable, at the option of Mortgagee upon 30
         days' notice to Mortgagor, notwithstanding anything contained herein or
         in any law heretofore or hereafter enacted, including any provision
         thereof forbidding Mortgagor from making any such payment. Mortgagor
         agrees to exhibit to Mortgagee, upon request, official receipts showing
         payment of all taxes and charges which Mortgagor is required to pay
         hereunder.

                    7. Recordation and Payment of Taxes and Expenses Incident
         Thereto. Mortgagor will maintain and preserve the lien of this Mortgage
         until all indebtedness hereby secured has been paid and satisfied in
         full. Without limiting the foregoing, Mortgagor will cause this
         Mortgage, all mortgages supplemental hereto and any financing statement
         or other notice of a security interest required by Mortgagee at all
         times to be kept, recorded and filed at its own expense in such manner
         and in such places as may be required by law for the recording and
         filing or for the rerecording and refiling of a mortgage, security
         interest, assignment or other lien or charge upon the Mortgaged
         Premises, or any part thereof, in order fully to preserve and protect
         the rights of Mortgagee hereunder and, without limiting the foregoing,
         Mortgagor will pay or reimburse Mortgagee and any Secured Creditor for
         the payment of any and all taxes, fees or other charges incurred in
         connection with any such recordation or rerecordation, including any
         documentary stamp tax or tax imposed upon the privilege of having this
         instrument or any instrument issued pursuant hereto recorded.

                    8. Insurance. Mortgagor will, at its expense, keep all
         buildings, improvements, equipment and other property now or hereafter
         constituting part of the Mortgaged Premises insured against loss or
         damage by fire, lightning, windstorm, explosion and such other risks as
         are usually included under extended coverage policies, or which are
         usually insured against by companies similarly situated conducting
         similar businesses and owning like properties, in amount sufficient to
         prevent Mortgagor, Mortgagee or the Secured Creditors from becoming a
         co-insurer of any partial loss under applicable policies and in any
         event not less than the then full insurable value (actual replacement
         value without deduction for physical depreciation) thereof, as
         determined at the request of Mortgagee and at Mortgagor's expense by
         the insurer or insurers or by an expert approved by Mortgagee, all
         under insurance policies payable, in case of loss or 


                                      -8-

<PAGE>   9

         damage, to Mortgagee (and if Mortgagee so requests, naming Mortgagee
         and the Secured Creditors as additional insureds therein), such rights
         to be evidenced by the usual standard non-contributory form of mortgage
         clause to be attached to each policy. Mortgagor shall not carry
         separate insurance concurrent in kind or form and contributing in the
         event of loss, with any insurance required hereby. Mortgagor shall also
         obtain and maintain public liability, property damage and workmen's
         compensation insurance in each case in form and content satisfactory to
         Mortgagee and in amounts as are customarily carried by owners of like
         property and approved by Mortgagee. Mortgagor shall also obtain and
         maintain such other insurance with respect to the Mortgaged Premises in
         such amounts and against such insurable hazards as Mortgagee from time
         to time may require, including, without limitation, boiler and
         machinery insurance, insurance against flood risks for any improvements
         located in a flood plain when and to the extent obtainable from the
         United States Government or any agency thereof, and insurance against
         loss of rent due to fire and risks now or hereafter embraced by
         so-called "extended coverage". All insurance required hereby shall be
         maintained with good and responsible insurance companies satisfactory
         to Mortgagee and shall not provide for any deductible amount in excess
         of $250,000 not approved in writing by Mortgagee, shall provide that
         any losses shall be payable notwithstanding any act or negligence of
         Mortgagor, shall provide that no cancellation thereof shall be
         effective until at least thirty days after receipt by Mortgagor and
         Mortgagee of written notice thereof, and shall be satisfactory to
         Mortgagee in all other respects. Upon the execution of this Mortgage
         and thereafter not less than 15 days prior to the expiration date of
         any policy delivered pursuant to this instrument, Mortgagor will
         deliver to Mortgagee certificates evidencing the policy or renewal
         policy, as the case may be, required by this instrument, bearing
         notations evidencing the payment of all premiums. In the event of
         foreclosure, Mortgagor authorizes and empowers Mortgagee to effect
         insurance upon the Mortgaged Premises in amounts aforesaid for a period
         covering the time of redemption from foreclosure sale provided by law,
         and if necessary therefor to cancel any or all existing insurance
         policies.

                    9.     Damage to or Destruction of Mortgaged Premises.

                            (a) Notice. In case of any material damage to or
                  destruction of the Mortgaged Premises or any part thereof,
                  Mortgagor shall promptly give written notice thereof to
                  Mortgagee, generally describing the nature and extent of such
                  damage or destruction.

                            (b) Restoration. In case of any damage to or
                  destruction of the Mortgaged Premises or any part thereof,
                  Mortgagor, whether or not the insurance proceeds, if any,
                  received on account of such damage or destruction shall be


                                      -9-
<PAGE>   10

                  sufficient for the purpose, at Mortgagor's expense, will
                  promptly commence and complete (subject to unavoidable delays
                  occasioned by strikes, lockouts, acts of God, inability to
                  obtain labor or materials, governmental restrictions and
                  similar causes beyond the reasonable control of Mortgagor) the
                  restoration, replacement or rebuilding of the Mortgaged
                  Premises as nearly as possible to its value, condition and
                  character immediately prior to such damage or destruction,
                  provided that any part of the Mortgaged Premises so damaged or
                  destroyed need not be restored, replaced or rebuilt if (i)
                  prior to its damage or destruction, it had become
                  uneconomical, obsolete or worn out or (ii) it is not necessary
                  for or of importance to the proper conduct of the Mortgagor's
                  business in the ordinary course.

                            (c) Adjustment of Loss. Mortgagor hereby authorizes
                  Mortgagee, at Mortgagee's option, to adjust and compromise any
                  losses under any insurance afforded at any time after the
                  occurrence and during the continuation of any event of default
                  hereunder or any event which with the lapse of time, the
                  giving of notice, or both, would constitute an event of
                  default hereunder (herein, a "default"), but unless Mortgagee
                  elects to adjust the losses as aforesaid, said adjustment
                  and/or compromise shall be made by Mortgagor, subject to final
                  approval of Mortgagee (regardless of whether or not a default
                  or event of default hereunder shall have occurred) in the case
                  of losses exceeding $250,000.

                            (d) Application of Insurance Proceeds. Net insurance
                  proceeds (except in cases where (i) the amount payable in
                  respect of any one loss, when combined with amounts paid in
                  respect of all losses incurred during any calendar year, is
                  less than $250,000 and (ii) an event of default hereunder
                  shall not have occurred and be continuing, in which case the
                  amount payable in respect of such loss may be received by
                  Mortgagor and need not be applied toward the payment of the
                  amount owing on the indebtedness hereby secured or for the
                  restoration of the Mortgaged Premises damaged or destroyed)
                  received by Mortgagee under the provisions of this Mortgage or
                  any instruments supplemental hereto or thereto or under any
                  policy or policies of insurance covering the Mortgaged
                  Premises or any part thereof shall first be applied toward the
                  payment of the amount owing on the indebtedness hereby secured
                  in such order of application as Mortgagee may elect whether or
                  not the same may then be due or be otherwise adequately
                  secured; provided, however, that such proceeds shall be made
                  available for the restoration of the portion of the Mortgaged
                  Premises damaged or destroyed if written application for such
                  use is made within thirty (30) days of receipt of such
                  proceeds and the following conditions are satisfied: (i)
                  Mortgagor has in effect business interruption insurance
                  covering the income to be lost during the 


                                      -10-
<PAGE>   11

         restoration period as a result of the damage or destruction to the
         Mortgaged Premises or provides Mortgagee with other evidence
         satisfactory to it that Mortgagor has cash resources sufficient to pay
         its obligations during the restoration period; (ii) no event of
         default, or event which, with the lapse of time, the giving of notice,
         or both, would constitute an event of default hereunder, shall have
         occurred or be continuing (and if such an event shall occur during
         restoration Mortgagee may, at its election, apply any insurance
         proceeds then remaining in its hands to the reduction of the
         indebtedness evidenced by the Notes and the other indebtedness hereby
         secured); (iii) Mortgagor shall have submitted to Mortgagee plans and
         specifications for the restoration which shall be satisfactory to it;
         (iv) Mortgagor shall submit to Mortgagee fixed price contracts with
         good and responsible contractors and materialmen covering all work and
         materials necessary to complete restoration and providing for a total
         completion price not in excess of the amount of insurance proceeds
         available for restoration, or, if a deficiency shall exist, Mortgagor
         shall have deposited the amount of such deficiency with Mortgagee and
         (v) Mortgagor shall have obtained a waiver of the right of subrogation
         from any insurer under such policies of insurance who at that time
         claims that no liability exists as to Mortgagor or the insured under
         such policies. Any insurance proceeds to be released pursuant to the
         foregoing provisions may at the option of Mortgagee be disbursed from
         time to time as restoration progresses to pay for restoration work
         completed and in place and such disbursements may at Mortgagee's option
         be made directly to Mortgagor or to or through any contractor or
         materialman to whom payment is due or to or through a construction
         escrow to be maintained by a title insurer acceptable to Mortgagee.
         Mortgagee may impose such further conditions upon the release of
         insurance proceeds (including the receipt of title insurance) as are
         customarily imposed by prudent construction lenders to insure the
         completion of the restoration work free and clear of all liens or
         claims for lien. All title insurance charges and other costs and
         expenses paid to or for the account of Mortgagor in connection with the
         release of such insurance proceeds shall constitute so much additional
         indebtedness hereby secured to be payable upon demand with interest at
         the Default Rate. Mortgagee may deduct any such costs and expenses from
         insurance proceeds at any time standing in its hands. If Mortgagor
         fails to request that insurance proceeds be applied to the restoration
         of the improvements or if Mortgagor makes such a request but fails to
         complete restoration within a reasonable time, Mortgagee shall have the
         right, but not the duty, to restore or rebuild said Mortgaged Premises
         or any part thereof for or on behalf of Mortgagor in lieu of applying
         said proceeds to the indebtedness hereby secured and for such purpose
         may do all necessary acts, including using funds deposited by Mortgagor
         as aforesaid and advancing additional funds for the purpose of
         restoration, all such 


                                      -11-
<PAGE>   12

                   additional funds to constitute part of the indebtedness
                   hereby secured payable upon demand with interest at the
                   Default Rate.

                   10. Eminent Domain. Mortgagor acknowledges that Condemnation
         Awards have been assigned to Mortgagee, which awards Mortgagee is
         hereby irrevocably authorized to collect and receive, and to give
         appropriate receipts and acquittances therefor, and at Mortgagee's
         option, to apply the same toward the payment of the amount owing on
         account of the indebtedness hereby secured in such order of application
         as Mortgagee may elect and whether or not the same may then be due and
         payable or otherwise adequately secured; provided, however, that a
         Condemnation Award in respect of any taking of a portion (but not all
         or any material portion) of the Mortgaged Premises shall be made
         available for the restoration of such Mortgaged Premises in the same
         manner and subject to the same conditions as are imposed on the release
         of insurance proceeds set forth in Section 9(d) hereof as if the
         Mortgaged Premises so taken were destroyed and the Condemnation Award
         for such taking was actually insurance proceeds in respect of the
         Mortgaged Premises so deemed as having been destroyed. In the event
         that any proceeds of a Condemnation Award shall be made available to
         Mortgagor for restoring the Mortgaged Premises so taken, Mortgagor
         hereby covenants to promptly commence and complete such restoration of
         the Mortgaged Premises as nearly as possible to its value, condition
         and character immediately prior to such taking. Mortgagor covenants and
         agrees that Mortgagor will give Mortgagee immediate notice of the
         actual or threatened commencement of any proceedings under condemnation
         or eminent domain affecting all or any material part of the Mortgaged
         Premises including any easement therein or appurtenance thereof or
         severance and consequential damage and change in grade of streets, and
         will deliver to Mortgagee copies of any and all papers served in
         connection with any such proceedings. Mortgagor further covenants and
         agrees to make, execute and deliver to Mortgagee, at any time or times
         upon request, free, clear and discharged of any encumbrances of any
         kind whatsoever, any and all further assignments and/or instruments
         deemed necessary by Mortgagee for the purpose of validly and
         sufficiently assigning all awards and other compensation heretofore and
         hereafter to be made to Mortgagor for any taking, either permanent or
         temporary, under any such proceeding.

                   11. Construction, Repair, Waste, Etc. Mortgagor agrees that
         no building or other improvement on the Mortgaged Premises and
         constituting a part thereof shall be materially altered, removed or
         demolished nor shall any material fixtures or appliances on, in or
         about said buildings or improvements be severed, removed, sold or
         mortgaged, without the consent of Mortgagee, and in the event of the
         demolition or destruction in whole or in part of any of the fixtures or
         articles of personal property covered hereby, Mortgagor covenants that
         the same will be replaced promptly by similar fixtures and 


                                      -12-
<PAGE>   13

                   articles of personal property at least equal in quality and
                   condition to those replaced, free from any security interest
                   in or encumbrance thereon or reservation of title thereto
                   other than liens permitted by the Credit Agreement and the
                   Permitted Exceptions; provided, however, that Mortgagor may
                   alter, remove or demolish any such building, improvement,
                   fixture or appliance, and need not replace any such fixtures
                   or personal property, in each case to the extent such action
                   (i) is desirable to the proper conduct of the business of
                   Mortgagor in the ordinary course as presently conducted and
                   otherwise in the best interest of Mortgagor, (ii) does not
                   impair the overall value or utility of the Mortgaged Premises
                   and Mortgagor's other related properties as an integrated
                   facility, (iii) does not decrease the efficiency or capacity
                   of the Mortgaged Premises and (iv) does not impair the rights
                   and benefits under this Mortgage of the Secured Creditors.
                   Mortgagor further agrees to permit, commit or suffer no
                   material waste, impairment or deterioration of the Mortgaged
                   Premises or any part thereof; to keep and maintain said
                   Mortgaged Premises and every part thereof in good working
                   condition (ordinary wear and tear excepted); to effect such
                   repairs as Mortgagee may reasonably require and from time to
                   time to make all needful and proper replacements and
                   additions so that said buildings, fixtures, machinery and
                   appurtenances will, at all times, be in good working
                   condition (ordinary wear and tear excepted), fit and proper
                   for the respective purposes for which they were originally
                   erected or installed; to comply with all statutes, orders,
                   requirements or decrees relating to the Mortgaged Premises by
                   any federal, state or municipal authority if the failure to
                   comply with such statutes, orders, requirements or decrees
                   could have a material adverse effect on the Mortgaged
                   Premises or the business or financial condition of the
                   Mortgagor; to observe and comply with all conditions and
                   requirements necessary to preserve and extend any and all
                   rights, licenses, permits (including, but not limited to,
                   zoning variances, special exceptions and non-conforming
                   uses), privileges, franchises and concessions which are
                   applicable to the Mortgaged Premises or which have been
                   granted to or contracted for by Mortgagor in connection with
                   any existing or presently contemplated use of the Mortgaged
                   Premises or any part thereof and not to initiate or acquiesce
                   in any changes to or terminations of any of the foregoing or
                   of zoning classifications affecting the use to which the
                   Mortgaged Premises or any part thereof may be put without the
                   prior written consent of Mortgagee; and to make no material
                   alterations in or improvements or additions to the Mortgaged
                   Premises except as required by governmental authority or as
                   permitted by Mortgagee. Mortgagor will not lease the
                   Mortgaged Premises or any material part thereof without the
                   prior written consent of Mortgagee, which consent shall not
                   be unreasonably withheld.

                   12. Liens and Encumbrances. Mortgagor will not, without the
         prior written consent of Mortgagee, directly or indirectly, create or
         suffer to be created or to remain and will discharge or promptly cause
         to be discharged any mortgage, lien, encumbrance or charge on, pledge
         of, or conditional sale or other title retention agreement with respect


                                      -13-
<PAGE>   14

         to, the Mortgaged Premises or any part thereof, whether superior or
         subordinate to the lien hereof, except for this instrument, liens
         permitted by the Credit Agreement and the Permitted Exceptions.

                   13. Right of Mortgagee to Perform Mortgagor's Covenants, Etc.
         If Mortgagor shall fail to make any payment or perform any act required
         to be made or performed hereunder, Mortgagee, without waiving or
         releasing any obligation or default, may (but shall be under no
         obligation to) at any time after notice to the Mortgagor make such
         payment or perform such act for the account and at the expense of
         Mortgagor, and may enter upon the Mortgaged Premises or any part
         thereof for such purpose and take all such action thereon as, in the
         opinion of Mortgagee, may be reasonably necessary or appropriate
         therefor. All sums so paid by Mortgagee and all reasonable costs and
         expenses (including without limitation attorney's fees and expenses) so
         incurred, together with interest thereon from the date of payment or
         incurrence at the Default Rate, shall constitute so much additional
         indebtedness hereby secured and shall be paid by Mortgagor to Mortgagee
         on demand. Mortgagee in making any payment authorized under this
         Section relating to taxes or assessments may do so according to any
         bill, statement or estimate procured from the appropriate public office
         without inquiry into the accuracy of such bill, statement or estimate
         or into the validity of any tax assessment, sale, forfeiture, tax lien
         or title or claim thereof.

                   14. After-Acquired Property. Any and all property hereafter
         acquired which is of the kind or nature herein provided, or intended to
         be and become subject to the lien hereof, shall ipso facto, and without
         any further conveyance, assignment or act on the part of Mortgagor,
         become and be subject to the lien of this Mortgage as fully and
         completely as though specifically described herein; but nevertheless
         Mortgagor shall from time to time, if requested by Mortgagee, execute
         and deliver any and all such further assurances, conveyances and
         assignments as Mortgagee may reasonably require for the purpose of
         expressly and specifically subjecting to the lien of this Mortgage all
         such property.

                   15. Inspection by Mortgagee. Mortgagee, any Secured Creditor
         and their respective representatives shall have the right to inspect
         the Mortgaged Premises at all reasonable times, and access thereto
         shall be permitted for that purpose; provided, however, that prior to
         the occurrence of any Default or Event of Default hereunder, any such
         access or inspection shall only be required during the Mortgagor's
         normal business hours and shall only be permitted with at least 24
         hours advance notice.

                   16. Reports on Mortgaged Premises. Mortgagor will furnish to
         Mortgagee or any Secured Creditor such information and data with
         respect to the Mortgaged Premises as Mortgagee or such Secured Creditor
         may reasonably request.

                                      -14-
<PAGE>   15

                   17. Subrogation. Mortgagor acknowledges and agrees that
         Mortgagee shall be subrogated to any lien discharged out of the
         proceeds of the loan evidenced by any Note or out of any advance by
         Mortgagee hereunder, irrespective of whether or not any such lien may
         have been released of record.

                   18. Events of Default. Any one or more of the following shall
         constitute an event of default hereunder:

                       (a) Failure to pay when due any indebtedness hereby
                   secured; or

                       (b) Any event occurs or condition exists which is
                   specified as an Event of Default under the Credit Agreement;
                   or

                       (c) The Mortgaged Premises or any material part thereof
                   shall be sold, transferred, or conveyed, whether voluntarily
                   or involuntarily, by operation of law or otherwise, except
                   for sales of obsolete, worn out or unusable fixtures or
                   personal property which are concurrently replaced (unless the
                   Mortgagor, in the exercise of its commercially reasonable
                   judgment deems such replacement not necessary or impractical
                   and such failure to replace would cause no material adverse
                   change in the Mortgaged Premises) with similar fixtures or
                   personal property at least equal in quality and condition to
                   those sold and owned by Mortgagor free of any lien, charge or
                   encumbrance other than the lien hereof; or

                       (d) Any indebtedness secured by a lien or charge on the
                   Mortgaged Premises or any part thereof is not paid when due
                   after the expiration of applicable grace periods and the
                   giving of applicable notices, if any (unless such
                   indebtedness is being contested in good faith by appropriate
                   proceedings which prevent the enforcement of the matter under
                   contest and adequate reserves have been established
                   therefor), or proceedings are commenced to foreclose or
                   otherwise realize upon any such lien or charge or to have a
                   receiver appointed for the property subject thereto or to
                   place the holder of such indebtedness or its representative
                   in possession thereof; or

                       (e) The Mortgaged Premises is abandoned.

                   19. Remedies. When any event of default has happened and is
         continuing (regardless of the pendency of any proceeding which has or
         might have the effect of preventing Mortgagor from complying with the
         terms of this instrument and of the adequacy of the security for the
         Notes, Letters of Credit and the other indebtedness 


                                      -15-

         hereby secured) and in addition to such other rights as may be
         available under applicable law, but subject at all times to any
         mandatory legal requirements:

                            (a) Acceleration. As and to the extent expressly
                  permitted by the Credit Agreement, Mortgagee may, by written
                  notice to Mortgagor, declare the Notes and all unpaid
                  indebtedness hereby secured, including the reimbursement
                  obligations of the Mortgagor in connection with any Letters of
                  Credit, including any interest then accrued thereon, to be
                  forthwith due and payable, whereupon the same shall become and
                  be forthwith due and payable, without other notice or demand
                  of any kind.

                            (b) Uniform Commercial Code. Mortgagee shall, with
                  respect to any part of the Mortgaged Premises constituting
                  property of the type in respect of which realization on a lien
                  or security interest granted therein is governed by the
                  Uniform Commercial Code, have all the rights, options and
                  remedies of a secured party under the Uniform Commercial Code
                  of Illinois, including without limitation, the right to the
                  possession of any such property, or any part thereof, and the
                  right to enter without legal process any premises where any
                  such property may be found. Any requirement of said Code for
                  reasonable notification shall be met by mailing written notice
                  to Mortgagor at its address above set forth at least 10
                  Business Days prior to the sale or other event for which such
                  notice is required. The expenses of retaking, selling, and
                  otherwise disposing of said property, including reasonable
                  attorney's fees and legal expenses incurred in connection
                  therewith, shall constitute so much additional indebtedness
                  hereby secured and shall be payable upon demand with interest
                  at the Default Rate.

                            (c) Foreclosure. Mortgagee may proceed to protect
                  and enforce the rights of Mortgagee or Secured Creditors
                  hereunder (i) by any action at law, suit in equity or other
                  appropriate proceedings, whether for the specific performance
                  of any agreement contained herein, or for an injunction
                  against the violation of any of the terms hereof, or in aid of
                  the exercise of any power granted hereby or by law, or (ii) by
                  the foreclosure of this Mortgage. Without limiting anything to
                  the contrary contained herein, to the extent permitted by
                  applicable law, Mortgagee in Mortgagee's sole discretion, may
                  elect to foreclose this Mortgage by means of non-judicial
                  foreclosure as permitted by Chapter 655A of the Code of Iowa.
                  By its execution hereof, Mortgagor hereby agrees that if
                  Mortgagor's waiver of redemption rights in Section 20 hereof
                  shall have no force and effect and if the real estate
                  described in Granting Clause I hereof is ten acres or less in
                  size, then the period of redemption after sale on any
                  foreclosure of this Mortgage shall be reduced to six months,
                  provided the Mortgagee waives in such 


                                      -16-

<PAGE>   17

                  foreclosure action any rights to a deficiency judgment against
                  the Mortgagor which might arise out of such foreclosure
                  proceedings, all to be consistent with the provisions of
                  Chapter 628 of the Code of Iowa. It is further hereby agreed
                  that if Mortgagee's waiver of redemption rights in Section 20
                  hereof shall have no force and effect and if the real estate
                  described in Granting Clause I hereof is ten acres or more in
                  size, then the period of redemption after sale on any
                  foreclosure of this Mortgage shall be reduced to sixty days
                  provided (i) the court with jurisdiction over such a
                  foreclosure action finds affirmatively in a decree of
                  foreclosure that said real estate has been abandoned by the
                  owners and those persons personally liable under the Mortgage
                  at the time of such foreclosure, and (ii) the Mortgagee waives
                  any rights to a deficiency judgment against the Mortgagor or
                  his successors in interest in the foreclosure action, all to
                  be consisted with the provisions of Chapter 628 of the Code of
                  Iowa. Nothing contained herein shall obligate Mortgagee to so
                  waive its rights to such a deficiency judgment in either case,
                  and the decision to do so shall be solely at the discretion of
                  Mortgagee. By its execution hereof, Mortgagor further hereby
                  agrees that, notwithstanding anything to the contrary
                  contained herein, Mortgagee may, at Mortgagee's sole
                  discretion, elect to foreclose upon the Mortgaged Premises
                  without redemption pursuant to the provisions of Section
                  654.20 of the Code of Iowa and may elect, at Mortgagee's sole
                  discretion, to so foreclose with or without a waiver of its
                  rights to a deficiency judgment.

                            (d) Appointment of Receiver. Mortgagee shall, as a
                  matter of right, without notice and without giving bond to
                  Mortgagor or anyone claiming by, under or through it, and
                  without regard to the solvency or insolvency of Mortgagor or
                  the then value of the Mortgaged Premises, be entitled to have
                  a receiver appointed of all or any part of the Mortgaged
                  Premises and the rents, issues and profits thereof, with such
                  power as the court making such appointment shall confer, and
                  Mortgagor hereby consents to the appointment of such receiver
                  and shall not oppose any such appointment. Any such receiver
                  may, to the extent permitted under applicable law, without
                  notice, enter upon and take possession of the Mortgaged
                  Premises or any part thereof by force, summary proceedings,
                  ejectment or otherwise, and may remove Mortgagor or other
                  persons and any and all property therefrom, and may hold,
                  operate and manage the same and receive all earnings, income,
                  rents, issues and proceeds accruing with respect thereto or
                  any part thereof, whether during the pendency of any
                  foreclosure or until any right of redemption shall expire or
                  otherwise.

                            (e) Taking Possession, Collecting Rents, Etc.
                  Mortgagee may enter and take possession of the Mortgaged
                  Premises or any part thereof and manage, 

                                      -17-

<PAGE>   18

                  operate, insure, repair and improve the same and take any
                  action which, in Mortgagee's reasonable judgment, is necessary
                  or proper to conserve the value of the Mortgaged Premises.
                  Mortgagee may also take possession of, and for these purposes
                  use, any and all personal property contained in the Mortgaged
                  Premises and used in the operation, rental or leasing thereof
                  or any part thereof. Mortgagee shall be entitled to collect
                  and receive all earnings, revenues, rents, issues and profits
                  of the Mortgaged Premises or any part thereof (and for such
                  purpose Mortgagor does hereby irrevocably constitute and
                  appoint Mortgagee its true and lawful attorney-in-fact for it
                  and in its name, place and stead to receive, collect and
                  receipt for all of the foregoing, Mortgagor irrevocably
                  acknowledging that any payment made to Mortgagee hereunder
                  shall be a good receipt and acquittance against Mortgagor to
                  the extent so made) and to apply same to the reduction of the
                  indebtedness hereby secured. The right to enter and take
                  possession of the Mortgaged Premises and use any personal
                  property therein, to manage, operate and conserve the same,
                  and to collect the rents, issues and profits thereof, shall be
                  in addition to all other rights or remedies of Mortgagee
                  hereunder or afforded by law, and may be exercised
                  concurrently therewith or independently thereof. The
                  reasonable expenses (including any receiver's fees, counsel
                  fees, costs and agent's compensation) incurred pursuant to the
                  powers herein contained shall be so much additional
                  indebtedness hereby secured which Mortgagor promises to pay
                  upon demand together with interest at the Default Rate.
                  Mortgagee shall not be liable to account to Mortgagor for any
                  action taken pursuant hereto other than to account for any
                  rents actually received by Mortgagee. Without taking
                  possession of the Mortgaged Premises, Mortgagee may, in the
                  event the Mortgaged Premises becomes vacant or is abandoned,
                  take such steps as it deems appropriate to protect and secure
                  the Mortgaged Premises (including hiring watchmen therefor)
                  and all reasonable costs incurred in so doing shall constitute
                  so much additional indebtedness hereby secured payable upon
                  demand with interest thereon at the Default Rate.

                   20. Waiver of Right to Redeem From Sale - Waiver of
         Appraisement, Valuation, Etc. Mortgagor shall not and will not apply
         for or avail itself of any appraisement, valuation, stay, extension or
         exemption laws, or any so-called "Moratorium Laws", now existing or
         hereafter enacted in order to prevent or hinder the enforcement or
         foreclosure of this Mortgage, but hereby waives the benefit of such
         laws. Mortgagor for itself and all who may claim through or under it
         waives any and all right to have the property and estates comprising
         the Mortgaged Premises marshalled upon any foreclosure of the lien
         hereof and agrees that any court having jurisdiction to foreclose such
         lien may order the Mortgaged Premises 

                                      -18-

         sold as an entirety. In the event of any sale made under or by virtue
         of this instrument, the whole of the Mortgaged Premises may be sold in
         one parcel as an entirety or in separate lots or parcels at the same or
         different times, all as the Mortgagee may determine. Mortgagee or any
         Secured Creditor shall have the right to become the purchaser at any
         sale made under or by virtue of this instrument; and Mortgagee or any
         Secured Creditor so purchasing at any such sale shall have the right to
         be credited upon the amount of the bid made therefor by Mortgagee or
         such Secured Creditor with the amount payable to Mortgagee or such
         Secured Creditor, as the case may be, out of the net proceeds of such
         sale, and upon compliance with the terms of sale, may hold, retain and
         possess and dispose of such property in its own absolute right without
         further accountability. In the event of any such sale, the Notes, the
         Reimbursement Obligations and the other indebtedness hereby secured, if
         not previously due, shall be and become immediately due and payable
         without demand or notice of any kind. Mortgagor hereby waives any and
         all rights of redemption prior to or from sale under any order or
         decree of foreclosure pursuant to rights herein granted, on behalf of
         Mortgagor, and each and every person acquiring any interest in, or
         title to the Mortgaged Premises described herein subsequent to the date
         of this Mortgage, and on behalf of all other persons to the extent
         permitted by applicable law.

                   21. Costs and Expenses of Foreclosure. In any suit to
         foreclose the lien hereof there shall be allowed and included as
         additional indebtedness in the decree for sale all reasonable
         expenditures and expenses which may be paid or incurred by or on behalf
         of Mortgagee or any Secured Creditor for attorney's fees, appraiser's
         fees, outlays for documentary and expert evidence, stenographic
         charges, publication costs and costs (which may be estimated as to
         items to be expended after the entry of the decree) of procuring all
         such abstracts of title, title searches and examination, guarantee
         policies, Torrens certificates and similar data and assurances with
         respect to title as Mortgagee or any Secured Creditor may deem to be
         reasonably necessary either to prosecute any foreclosure action or to
         evidence to the bidder at any sale pursuant thereto the true condition
         of the title to or the value of the Mortgaged Premises, all of which
         expenditures shall become so much additional indebtedness hereby
         secured which Mortgagor agrees to pay and all of such shall be
         immediately due and payable with interest thereon from the date of
         expenditure until paid at the Default Rate.

                   22. Application of Proceeds. The proceeds and avails of the
         Mortgaged Premises, including without limitation the proceeds of any
         foreclosure sale of the Mortgaged Premises or of any sale of property
         pursuant to Section l9(b) hereof, shall, when received by Mortgagee in
         cash or its equivalent, be applied by the Mortgagee as set forth in
         Section 3.5 of the Credit Agreement. Mortgagor shall remain liable to
         Mortgagee and the Secured Creditors for any deficiency. Any surplus
         remaining after the full payment and satisfaction of the foregoing
         shall be returned to Mortgagor or to whomsoever a court of competent
         jurisdiction shall determine to be entitled thereto.

                                      -19-
<PAGE>   20

                   23. Deficiency Decree. If at any foreclosure proceeding the
         Mortgaged Premises shall be sold for a sum less than the total amount
         of indebtedness for which judgment is therein given, the judgment
         creditor shall be entitled to the entry of a deficiency decree against
         Mortgagor and against the property of Mortgagor for the amount of such
         deficiency; and Mortgagor does hereby irrevocably consent to the
         appointment of a receiver for the Mortgaged Premises and the property
         of Mortgagor and of the rents, issues and profits thereof after such
         sale and until such deficiency decree is satisfied in full.

                   24. Mortgagee's Remedies Cumulative - No Waiver. No remedy or
         right of Mortgagee shall be exclusive of but shall be cumulative and in
         addition to every other remedy or right now or hereafter existing at
         law or in equity or by statute or otherwise. No delay in the exercise
         or omission to exercise any remedy or right accruing on any default
         shall impair any such remedy or right or be construed to be a waiver of
         any such default or acquiescence therein, nor shall it affect any
         subsequent default of the same or a different nature. Every such remedy
         or right may be exercised concurrently or independently, and when and
         as often as may be deemed expedient by Mortgagee.

                   25. Mortgagee Party to Suits. Mortgagee shall have the power
         and authority (but not the duty) to institute and maintain any suits
         and proceedings as Mortgagee may deem advisable (a) to prevent any
         impairment of the Mortgaged Premises by any acts which may be unlawful
         or which violate the terms of this Mortgage, (b) to preserve or protect
         its interest in the Mortgaged Premises or (c) to restrain the
         enforcement of or compliance with any legislation or other governmental
         enactment, rule or order that may be unconstitutional or otherwise
         invalid, if the enforcement of or compliance with such enactment, rule
         or order might impair the security hereunder or be prejudicial to
         Mortgagee's or Secured Creditor's interest. If Mortgagee or any Secured
         Creditor shall be made a party to or shall intervene in any action or
         proceeding affecting the Mortgaged Premises or the title thereto or the
         interest of Mortgagee or any Secured Creditor under this Mortgage
         (including probate and bankruptcy proceedings), or if Mortgagee or any
         Secured Creditor employs an attorney to collect any or all of the
         indebtedness hereby secured or to enforce any of the terms hereof or
         realize hereupon or to protect the lien hereof, or if Mortgagee or any
         Secured Creditor shall incur any costs or expenses in preparation for
         the commencement of any foreclosure proceedings or for the defense of
         any threatened suit or proceeding which might affect the Mortgaged
         Premises or the security hereof, whether or not any such foreclosure or
         other suit or proceeding shall be actually commenced, then in any such
         case, Mortgagor agrees to pay to Mortgagee or such Secured Creditor, as
         the case may be, immediately and without demand, all reasonable costs,
         charges, expenses and attorney's fees incurred by Mortgagee or such


                                      -20-
<PAGE>   21

         Secured Creditor in any such case, and the same shall constitute so
         much additional indebtedness hereby secured payable upon demand with
         interest at the Default Rate.

                   26. Modifications Not to Affect Lien. Mortgagee, without
         notice to anyone (except the Secured Lenders), and without regard to
         the consideration, if any, paid therefor, or the presence of other
         liens on the Mortgaged Premises, may at the direction of the Secured
         Lenders release any part of the Mortgaged Premises or any person liable
         for any of the indebtedness hereby secured, may extend the time of
         payment of any of the indebtedness hereby secured and may grant waivers
         or other indulgences with respect hereto and thereto, and may agree
         with Mortgagor to modifications to the terms and conditions contained
         herein or otherwise applicable to any of the indebtedness hereby
         secured (including modifications in the rates of interest applicable
         thereto), without in any way affecting or impairing the liability of
         any party liable upon any of the indebtedness hereby secured or the
         priority of the lien of this Mortgage upon all of the Mortgaged
         Premises not expressly released, and any party acquiring any direct or
         indirect interest in the Mortgaged Premises shall take same subject to
         all of the provisions hereof.

                   27. Revolving Credit Loan. This Mortgage is given to secure,
         among other things, a revolving credit loan and shall secure not only
         presently existing indebtedness under the Credit Agreement but also
         future advances, or otherwise, as are made within twenty (20) years
         from the date hereof, to the same extent as if such future advances
         were made on the date of the execution of this Mortgage, although there
         may be no advance made at the time of execution of this Mortgage and
         although there may be no indebtedness hereby secured outstanding at the
         time any advance is made. The lien of this Mortgage shall be valid as
         to all indebtedness hereby secured, including future advances, from the
         time of its filing for record in the recorder's or registrar's office
         of the county in which the Mortgaged Premises are located. The total
         amount of indebtedness hereby secured may increase or decrease from
         time to time, but the total unpaid balance of indebtedness hereby
         secured (including disbursements which Mortgagee may make under this
         Mortgage, the Credit Agreement or any other documents related thereto)
         at any one time outstanding shall not exceed a maximum principal amount
         of One Hundred Million Dollars ($100,000,000) plus interest thereon and
         any disbursements made for payment of taxes, special assessments or
         insurance on the Mortgaged Premises and interest on such disbursements
         (all such indebtedness being hereinafter referred to as the "maximum
         amount secured hereby"). This Mortgage shall be valid and have priority
         over all subsequent liens and encumbrances, including statutory liens,
         excepting solely taxes and assessments levied on the Mortgaged
         Premises, to the extent of the maximum amount secured hereby.

         provided herein are intended to be limited to the extent necessary so
         that they will not render this Mortgage invalid, unenforceable or not

         If any term of this Mortgage shall be held to be invalid, illegal or

                                      -24-

         unenforceable, the validity and enforceability of the other terms of
         this Mortgage shall in no way be affected thereby.

                   34. Agent. Mortgagee has been appointed as agent pursuant to
         the Credit Agreement. In acting under or by virtue of this Mortgage,
         Mortgagee shall be entitled to all the rights, authority, privileges
         and immunities provided in Section 10 of the Credit Agreement, all of
         which provisions of said Section 10 are incorporated by reference
         herein with the same force and effect as if set forth herein. Mortgagee
         hereby disclaims any representation or warranty to Secured Creditors
         concerning the perfection of the security interest granted hereunder or
         the value of the Mortgaged Premises.

                   35. Restrictions on Secured Creditors' Right to Enforce. No
         Secured Creditor shall have the right to institute any suit, action or
         proceeding in equity or at law for the foreclosure of this Mortgage or
         for the execution of any trust or power hereof or for the appointment
         of a receiver, or for the enforcement of any other remedy under or upon
         this Mortgage; it being understood and intended that no one or more of
         the Secured Creditors shall have any right in any manner whatsoever to
         affect, disturb or prejudice the lien of this Mortgage by its or their
         action or to enforce any right hereunder, and that all proceedings at
         law or in equity shall be instituted, had and maintained by the

         the Secured Creditors.

                   36. Successors and Assigns. Whenever any of the parties
         hereto is referred to, such reference shall be deemed to include the
         successors and assigns of such party; and all the covenants, promises
         and agreements in this Mortgage contained by or on behalf of Mortgagor,
         or by or on behalf of Mortgagee or Secured Creditors, shall bind and
         inure to the benefit of the respective successors and assigns of such
         parties, whether so expressed or not. Without limiting the generality
         of the foregoing, and subject to the provisions of Sections 12.14 and
         12.15 of the Credit Agreement, any Lender may assign or otherwise
         transfer any indebtedness held by it secured by this Mortgage to any
         other person or entity, and such other person or entity shall thereupon
         become vested with all the benefits in respect thereof granted to such
         Lender herein or otherwise, subject, however, to the provisions of the
         Credit Agreement.

                   37. Default Rate. For purposes of this Mortgage, "Default

                   38. Liens Absolute, Etc. Mortgagor acknowledges and agrees
         that the lien and security interest hereby created and provided for are
         absolute and unconditional and shall not in any manner be affected or

         holder of any of the indebtedness hereby secured, and without

                                      -25-
<PAGE>   26

         limiting the generality of the foregoing, the lien and security hereof
         shall not be impaired by any acceptance by Mortgagee or any other
         holder of any of the indebtedness hereby secured of any other security
         for or guarantors upon any of the indebtedness hereby secured or by any
         failure, neglect or omission on the part of Mortgagee or any other
         holder of any of the indebtedness hereby secured to realize upon or
         protect any of the indebtedness hereby secured or any collateral or
         security therefor. The lien and security interest hereof shall not in
         any manner be impaired or affected by (and Mortgagee, without notice to
         anyone, is hereby authorized to make from time to time) any sale,
         pledge, surrender, compromise, settlement, release, renewal, extension,
         indulgence, alteration, substitution, exchange, change in, modification
         or disposition of any of the indebtedness hereby secured, or of any
         collateral or security therefor, or of any guaranty thereof, or of any
         instrument or agreement setting forth the terms and conditions
         pertaining to any of the foregoing. The Secured Creditors may at their
         discretion at any time grant credit to the Borrower without notice to
         Mortgagor in such amounts and on such terms as such Secured Creditors
         may elect without in any manner impairing the lien and security
         interest created and provided for herein. In order to realize hereon
         and to exercise the rights granted Mortgagee hereby and under
         applicable law, there shall be no obligation on the part of Mortgagee
         or any other holder of any of the indebtedness hereby secured at any
         time to first resort for payment to the Borrower or to any guaranty of
         any of the indebtedness hereby secured or any portion thereof or to
         resort to any other collateral, security, property, liens or any other
         rights or remedies whatsoever, and Mortgagee shall have the right to
         enforce this Mortgage irrespective of whether or not other proceedings
         or steps seeking resort to or realization upon or from any of the
         foregoing are pending.

                   39. Direct and Primary Security - No Subrogation. The lien
         and security interest herein created and provided for stand as direct
         and primary security for the Notes as well as for any of the other
         indebtedness hereby secured. No application of any sums received by
         Mortgagee in respect of the Mortgaged Premises or any disposition
         thereof to the reduction of the indebtedness hereby secured or any part
         thereof shall in any manner entitle Mortgagor to any right, title or
         interest in or to the indebtedness hereby secured or any collateral or
         security therefor, whether by subrogation or otherwise, unless and
         until all indebtedness hereby secured has been fully paid and satisfied
         and any commitment of the Secured Creditors to extend credit to
         Mortgagor or to the Borrower shall have expired.

                   40. Multisite Real Estate Transaction. Mortgagor acknowledges
         that this Mortgage is one of a number of other mortgages and deeds of
         trusts and other security documents dated of even date herewith (such
         mortgages, deeds of trust and other security documents dated of even
         date herewith and any supplements or amendments thereto and 


                                      -26-
<PAGE>   27

         any other mortgages, deeds of trust or security documents securing the
         indebtedness hereby secured are collectively called the "Other
         Mortgages") which secure the indebtedness hereby secured. Mortgagor
         agrees that the lien of this Mortgage shall be absolute and
         unconditional and shall not in any manner be affected or impaired by
         any acts or omissions whatsoever of Mortgagee and, without limiting the
         generality of the foregoing, the lien hereof shall not be impaired by
         any acceptance by Mortgagee of any security for or guarantors upon any
         of the indebtedness hereby secured, or by any failure, neglect or
         omission on the part of the Mortgagee to realize upon or protect any of
         the indebtedness hereby secured or any collateral security therefor
         including the Other Mortgages. The lien hereof shall not in any manner
         be impaired or affected by any release (except as to the property
         released) sale, pledge, surrender, compromise, settlement, renewal,
         extension, indulgence, alteration, changing, modification or
         disposition of any of the indebtedness hereby secured or of any of the
         collateral security therefor, including without limitation the Other
         Mortgages or of any guarantee thereof, and Mortgagee may at its
         discretion foreclose, exercise any power of sale, or exercise any other
         remedy available to it under any or all of the Other Mortgages without
         first exercising or enforcing any of its rights and remedies hereunder.
         Such exercise of Mortgagee's rights and remedies under any or all of
         the Other Mortgages shall not in any manner impair the indebtedness
         hereby secured or the lien of this Mortgage and any exercise of the
         rights or remedies of Mortgagee hereunder shall not impair the lien of
         any of the Other Mortgages or any of Mortgagee's rights and remedies
         thereunder. The undersigned specifically consents and agrees that
         Mortgagee may exercise its rights and remedies hereunder and under the
         Other Mortgages separately or concurrently and in any order that it may
         deem appropriate.

                   41. Headings. The headings in this instrument are for
         convenience of reference only and shall not limit or otherwise affect
         the meaning of any provision hereof.

                   42. Changes, Etc. This instrument and the provisions hereof
         may be changed, waived, discharged or terminated only by an instrument
         in writing signed by the party against which enforcement of the change,
         waiver, discharge or termination is sought.

                   43. Notice. This mortgage secures credit in the principal
         amount of $90,000,000. Loans and advances up to this amount, together
         with interest, are senior to indebtedness to other creditors under
         subsequently recorded or filed mortgages and liens.

                           The $90,000,000 credit referred to in this Section 43
         is the principal amount of such credit and this Mortgage also secures
         all other indebtedness hereby secured in addition to that part of the
         indebtedness hereby secured which represents the principal amount of
         such credit.

Trust, Grantor hereby sells, transfers and assigns to Beneficiary all right,
title and interest of Grantor, and Grantor does hereby authorize, empower and
grant to Beneficiary the right, but not the obligation, to collect, receive and
receipt for all such rents and other sums and apply them to the indebtedness
hereby secured and to demand, sue for and recover the same when due or payable;
provided that the assignments made hereby shall not impair or diminish the
obligations of Grantor under the provisions of such leases or other agreements
nor shall such obligations be imposed upon Trustee. By acceptance of this Deed
of Trust, Beneficiary agrees, not as a limitation or condition hereof, but as a
personal covenant available only to Grantor, that until an event of default (as
hereinafter defined) shall occur Grantor may collect, receive (but not more than
30 days in advance) and enjoy such rents.


                               GRANTING CLAUSE IV

         All judgments, awards of damages, settlements and other compensation
heretofore or hereafter made resulting from condemnation proceedings or the
taking of the property described in Granting Clause I or any part thereof or any
building or other improvement now or at any time hereafter located thereon or
any easement or other appurtenance thereto under the power of eminent domain, or
any similar power or right (including any award from the United States
Government at any time after the allowance of the claim therefor, the
ascertainment of the amount thereof and the issuance of the warrant for the
payment thereof), whether permanent or temporary, or for any damage (whether
caused by such taking or otherwise) to said property or any part thereof or the
improvements thereon or any part thereof, or to any rights appurtenant thereto,
including severance and consequential damage, and any award for change of grade
of streets (collectively "Condemnation Awards").


                                GRANTING CLAUSE V

         All property and rights, if any, which are by the express provisions of
this instrument required to be subjected to the lien hereof and any additional
property and rights that may from time to time hereafter, by installation or
writing of any kind, be subjected to the lien hereof by Grantor or by anyone on
Grantor's behalf.


                               GRANTING CLAUSE VI

         All rights in and to common areas and access roads on adjacent
properties heretofore or hereafter granted to Grantor and any after-acquired
title or reversion in and to the beds of any

ways, roads, streets, avenues and alleys adjoining the property described in 
Granting Clause I or any part thereof.

         TO HAVE AND TO HOLD the Mortgaged Premises and the properties, rights
and privileges hereby granted, bargained, sold, conveyed, warranted, pledged and
assigned, and in which a security interest is granted, or intended so to be, in
trust unto Trustee, its successors and assigns, in fee simple forever; provided,
however, that this instrument is upon the express condition that if the
principal of and interest on the Revolving Credit Notes shall be paid in full
and all other indebtedness hereby secured shall be fully paid and performed,
then this instrument and the estate and rights hereby granted shall cease,
determine and be void and this instrument shall be released by Trustee upon the
written request and at the expense of Grantor, otherwise to remain in full force
and effect.

         IN TRUST NEVERTHELESS, upon the terms and trust herein set forth, for
the equal and proportionate benefit, security and protection of all present and
future holders of the indebtedness hereby secured; provided, however, that this
instrument is upon the express condition that if all of the indebtedness hereby
secured shall have been paid and performed in full and any commitment in the
Credit Agreement to advance funds shall have terminated, then this instrument
and the estate and rights hereby granted shall cease, determine and be void and
upon the written request and at the expense of Grantor, the Beneficiary shall
request Trustee to release this Deed of Trust and shall produce for Trustee the
Revolving Credit Notes duly cancelled, the Trustee to then release this Deed of
Trust without further inquiry or liability; otherwise this Deed of Trust is to
remain in full force and effect.

         Grantor hereby covenants and agrees with Trustee and the Beneficiary as
follows:

               Section 1. Payment of the Indebtedness. The indebtedness hereby
secured will be promptly paid as and when the same becomes due.

               Section 2. Further Assurances. Grantor will execute and deliver
such further instruments and do such further acts as may be necessary or proper
to carry out more effectively the purpose of this instrument and, without
limiting the foregoing, to make subject to the lien hereof any property agreed
to be subjected hereto or covered by the Granting Clauses hereof or intended so
to be.

               Section 3. Possession. While Grantor is not in default hereunder,
Grantor shall be suffered and permitted to remain in full possession, enjoyment
and control of the Mortgaged Premises, subject always to the observance and
performance of the terms of this instrument.

                                      -6-
<PAGE>   7

               Section 4. Payment of Taxes. Grantor shall pay before any penalty
attaches, all general taxes and all special taxes, special assessments, water,
drainage and sewer charges and all other charges of any kind whatsoever,
ordinary or extraordinary, which may be levied, assessed, imposed or charged on
or against the Mortgaged Premises or any part thereof and which, if unpaid,
might by law become a lien or charge upon the Mortgaged Premises or any part
thereof, and shall, upon written request, exhibit to Trustee or Beneficiary
official receipts evidencing such payments, except that, unless and until
foreclosure, distraint, sale or other similar proceedings shall have been
commenced, no such charge or claim need be paid if being contested (except to
the extent any full or partial payment shall be required by law), after notice
to Trustee or Beneficiary, by appropriate proceedings which shall operate to
prevent the collection thereof or the sale or forfeiture of the Mortgaged
Premises or any part thereof to satisfy the same, conducted in good faith and
with due diligence.

               Section 5. Payment of Taxes on Notes, Deed of Trust or Interest
of Trustee or Beneficiary. Without duplication of the Grantor's obligations
under Section 12 of the Credit Agreement, Grantor agrees that if any tax,
assessment or imposition upon this Deed of Trust or the indebtedness hereby
secured or the Revolving Credit Notes or the interest of Trustee or Beneficiary
in the Mortgaged Premises or upon Trustee or Beneficiary by reason of or as a
holder of any of the foregoing (including, without limitation, corporate
privilege, franchise and excise taxes, but excepting therefrom any income tax on
interest payments on the principal portion of the indebtedness hereby secured
imposed by the United States or any state) is levied, assessed or charged, then,
unless all such taxes are paid by Grantor to, for or on behalf of Trustee or
Beneficiary as they become due and payable (which Grantor agrees to do upon
demand of Trustee or Beneficiary, to the extent permitted by law), or Trustee or
Beneficiary is reimbursed for any such sum advanced by Trustee or Beneficiary,
all sums hereby secured shall become immediately due and payable, at the option
of Trustee or Beneficiary upon 30 days' notice to Grantor, notwithstanding
anything contained herein or in any law heretofore or hereafter enacted,
including any provision thereof forbidding Grantor from making any such payment.
Grantor agrees to exhibit to Trustee or Beneficiary, upon request, official
receipts showing payment of all taxes and charges which Grantor is required to
pay hereunder. Beneficiary shall provide to Grantor a statement setting forth
the nature and amount of any such tax or charge. Grantor may contest any such
tax, assessment or imposition in good faith and in appropriate proceedings which
prevent enforcement of the matter under contest.

               Section 6. Recordation and Payment of Taxes and Expenses Incident
Thereto. Grantor will pay or reimburse Trustee or Beneficiary for the payment of
any and all taxes, fees or other charges incurred in connection with any such
recordation or rerecordation, including any documentary stamp tax or tax imposed
upon the privilege of having this instrument or any instrument issued pursuant
hereto recorded.

                                      -7-
<PAGE>   8

               Section 7. Insurance. Grantor will, at its expense, keep all
buildings, improvements, equipment and other property now or hereafter
constituting part of the Mortgaged Premises insured against loss or damage by
fire, lightning, windstorm, explosion and such other risks as are usually
included under extended coverage policies, or which are usually insured against
by companies similarly situated conducting similar businesses and owning like
properties, in amount sufficient to prevent Grantor, Beneficiary or the Secured
Creditors from becoming a co-insurer of any partial loss under applicable
policies and in any event not less than the then full insurable value (actual
replacement value without deduction for physical depreciation) thereof, as
determined at the reasonable request of Beneficiary and at Grantor's expense by
the insurer or insurers, all under insurance policies payable, in case of loss
or damage, to Beneficiary (and if Beneficiary so requests, naming Beneficiary
and the Secured Creditors as additional insureds therein), such rights to be
evidenced by the usual standard non-contributory form of mortgage clause to be
attached to each policy. Grantor shall not carry separate insurance concurrent
in kind or form and contributing in the event of loss, with any insurance
required hereby. Grantor shall also obtain and maintain public liability,
property damage and workmen's compensation insurance in each case in form and
content reasonably satisfactory to Beneficiary and in amounts as are customarily
carried by owners of like property. Grantor shall also obtain and maintain such
other insurance with respect to the Mortgaged Premises in such amounts and
against such insurable hazards as Beneficiary from time to time may reasonably
require, including, without limitation, boiler and machinery insurance and
insurance against risks now or hereafter embraced by so called "extended
coverage." All insurance required hereby shall be maintained with good and
responsible insurance companies reasonably satisfactory to Beneficiary and may
provide for deductible amounts as are customary for Persons similarly situated,
conducting similar businesses and operating like properties, shall provide that
any losses shall be payable notwithstanding any act or negligence of Grantor,
shall provide that no cancellation thereof shall be effective until at least
thirty days after receipt by Grantor and Beneficiary of written notice thereof,
and shall be reasonably satisfactory to Beneficiary in all other respects. Upon
the execution of this Deed of Trust and thereafter not less than fifteen (15)
days prior to the expiration date of any policy delivered pursuant to this
instrument, Grantor will deliver to Beneficiary certificates evidencing the
insurance required by this instrument. In the event of foreclosure, Grantor
authorizes and empowers Beneficiary to effect insurance upon the Mortgaged
Premises in amounts aforesaid for a period covering the time of redemption from
foreclosure sale provided by law, and if necessary therefor to cancel any or all
existing insurance policies.

               Section 8.    Damage to or Destruction of Mortgaged Premises.

                   (a) Notice. In case of any material damage to or destruction
         of the Mortgaged Premises or any part thereof, Grantor shall promptly
         give written notice thereof to Trustee or Beneficiary, generally
         describing the nature and extent of such damage or destruction.

                                      -8-
<PAGE>   9

                   (b) Restoration. In case of any damage to or destruction of
         the Mortgaged Premises or any part thereof, Grantor, whether or not the
         insurance proceeds, if any, received on account of such damage or
         destruction shall be sufficient for the purpose, at Grantor's expense,
         will promptly commence and complete (subject to unavoidable delays
         occasioned by strikes, lockouts, acts of God, inability to obtain labor
         or materials, governmental restrictions and similar causes beyond the
         reasonable control of Grantor) the restoration, replacement or
         rebuilding of the Mortgaged Premises as nearly as possible to its
         value, condition and character immediately prior to such damage or
         destruction unless the Grantor, in the exercise of its commercially
         reasonable judgment, deems it unnecessary or inappropriate to replace,
         restore or rebuild the Mortgaged Premises; provided, however, that (i)
         Grantor need not restore, replace or rebuild the Mortgaged Premises so
         damaged or destroyed to the extent Grantor could have demolished and
         not replaced such property without Beneficiary's consent in compliance
         with Section 11 hereof and (ii) Grantor shall not be in default of its
         obligation hereunder to promptly commence such restoration, replacement
         or rebuilding by delaying such commencement until its receipt of the
         insurance proceeds on account of such damage or destruction if (a)
         Grantor has in effect the insurance required by this Deed of Trust, (b)
         Grantor is in compliance with the conditions hereinafter set forth to
         Beneficiary's obligation to release such proceeds to Grantor for such
         restoration, replacement or rebuilding, (c) such delay does not in any
         event exceed ninety (90) days and (c) pending its receipt of such
         proceeds, Grantor diligently follows the procedures set out in the
         policies of such insurance for making a claim thereon against the
         insurer.

                   (c) Adjustment of Loss. Grantor hereby authorizes
         Beneficiary, upon the occurrence and during the continuation of any
         event of default hereunder, at Beneficiary's option, to adjust and
         compromise any losses under any insurance afforded, but unless
         Beneficiary elects to adjust the losses as aforesaid, said adjustment
         and/or compromise shall be made by Grantor, subject to final approval
         of Beneficiary in the case of losses exceeding $250,000.

                   (d) Application of Insurance Proceeds. Net insurance proceeds
         (except in cases where (i) the amount payable in respect of any one
         loss is less than $250,000 and (ii) and an event of default hereunder
         shall not have occurred and be continuing, in which case the amount
         payable in respect of such loss may be received by Grantor, and to the
         extent required by subdivision (b) of this Section, used by Grantor in
         paying for restoration, replacement or rebuilding of the damaged or
         destroyed property) received by Beneficiary under the provisions of
         this Deed of Trust or any instruments supplemental hereto or thereto or
         under any policy or policies of insurance covering the Mortgaged
         Premises or any part thereof shall first be applied toward the payment
         of the amount owing on the indebtedness hereby secured in such order of
         application as Beneficiary 


                                      -9-
<PAGE>   10

         may elect whether or not the same may then be due or be otherwise
         adequately secured; provided, however, that such proceeds shall be made
         available for the restoration of the portion of the Mortgaged Premises
         damaged or destroyed if written application for such use is made within
         thirty (30) days of receipt of such proceeds and the following
         conditions are satisfied: (i) in the reasonable judgment of
         Beneficiary, the Mortgaged Premises can be restored within a reasonable
         time to an architectural and economic unit of the same character and
         such that the overall value and utility of the Mortgaged Premises and
         the Grantor's other properties as an integrated operating facility,
         including the efficiency and capacity thereof, after such restoration
         shall be no less than was the case prior to such damage or destruction;
         (ii) Grantor has in effect business interruption insurance covering the
         income to be lost during the restoration period as a result of the
         damage or destruction to the Mortgaged Premises or provides Beneficiary
         with other evidence reasonably satisfactory to it that Grantor has cash
         resources sufficient to pay its obligations during the restoration
         period; (iii) at the time of release no event of default hereunder, or
         event which, with the lapse of time, the giving of notice, or both,
         would constitute an event of default, shall have occurred or be
         continuing; (iv) Grantor shall have submitted to Beneficiary plans and
         specifications for the restoration which shall be reasonably
         satisfactory to it; (v) Grantor shall submit to Beneficiary contracts
         reasonably acceptable to Beneficiary with good and responsible
         contractors and materialmen covering substantially all work and
         materials necessary to complete restoration and providing for a total
         completion price not in excess of the amount of insurance proceeds
         available for restoration, or, if a deficiency shall exist, Grantor
         shall have deposited the amount of such deficiency with Beneficiary;
         and (vi) Grantor shall have obtained a waiver of the right of
         subrogation from any insurer under such policies of insurance who at
         that time claims that no liability exists as to Grantor or the insured
         under such policies. Any insurance proceeds to be released pursuant to
         the foregoing provisions may at the option of Beneficiary be disbursed
         from time to time as restoration progresses to pay for restoration work
         completed and in place and such disbursements may at Beneficiary's
         option be made directly to Grantor or to or through any contractor or
         materialman to whom payment is due or to or through a construction
         escrow to be maintained by a title insurer acceptable to Beneficiary.
         Beneficiary may impose such further conditions upon the release of
         insurance proceeds (including the receipt of title insurance) as are
         customarily imposed by prudent construction lenders to insure the
         completion of the restoration work free and clear of all liens or
         claims for lien other than liens permitted by the Credit Agreement and
         the Permitted Exceptions (as hereinafter defined). All title insurance
         charges and other costs and expenses paid to or for the account of
         Grantor in connection with the release of such insurance proceeds shall
         constitute so much additional indebtedness hereby secured to be payable
         upon demand with interest at the Default Rate (as hereinafter defined).
         Beneficiary may deduct any such costs and expenses from insurance
         proceeds at any time standing in its hands. If Grantor fails to 


                                      -10-
<PAGE>   11

         request that insurance proceeds be applied to the restoration of the
         improvements or if Grantor makes such a request but fails to complete
         restoration within a reasonable time, Beneficiary shall have the right,
         but not the duty, to restore or rebuild said Mortgaged Premises or any
         part thereof for or on behalf of Grantor in lieu of applying said
         proceeds to the indebtedness hereby secured and for such purpose may do
         all necessary acts, including using funds deposited by Grantor as
         aforesaid and advancing additional funds for the purpose of
         restoration, all such additional funds to constitute part of the
         indebtedness hereby secured payable upon demand with interest at the
         Default Rate.

               Section 9. Eminent Domain. Grantor acknowledges that Condemnation
Awards have been assigned to Beneficiary, which awards Beneficiary is hereby
irrevocably authorized to collect and receive, and to give appropriate receipts
and acquittances therefor, and at Beneficiary's option, to apply the same toward
the payment of the amount owing on account of the indebtedness hereby secured in
such order of application as Beneficiary may elect and whether or not the same
may then be due and payable or otherwise adequately secured; provided, however,
that a Condemnation Award in respect of any taking of a portion (but not all or
any material portion) of the Mortgaged Premises shall be made available for the
restoration of such Mortgaged Premises in the same manner and subject to the
same conditions as are imposed on the release of insurance proceeds set forth in
Section 9(d) hereof (including the provision of such Section relating to net
insurance proceeds less than $250,000) as if the Mortgaged Premises so taken
were destroyed and the Condemnation Award for such taking was actually insurance
proceeds in respect of the Mortgaged Premises so deemed as having been
destroyed. In the event that any proceeds of a Condemnation Award shall be made
available to Grantor for restoring the Mortgaged Premises so taken, Grantor
hereby covenants to promptly commence and complete such restoration of the
Mortgaged Premises as nearly as possible to its value, condition and character
immediately prior to such taking. Grantor covenants and agrees that Grantor will
give Beneficiary prompt notice of the actual or threatened commencement of any
proceedings under condemnation or eminent domain affecting all or any part of
the Mortgaged Premises including any easement therein or appurtenance thereof or
severance and consequential damage and change in grade of streets, and will
deliver to Beneficiary copies of any and all papers served in connection with
any such proceedings. Grantor further covenants and agrees to make, execute and
deliver to Beneficiary, at any time or times upon request, free, clear and
discharged of any encumbrances of any kind whatsoever, any and all further
assignments and/or instruments deemed necessary by Beneficiary for the purpose
of validly and sufficiently assigning all awards and other compensation
heretofore and hereafter to be made to Grantor for any taking, either permanent
or temporary, under any such proceeding.

              Section 10. Construction, Repair, Waste, Etc. Grantor agrees that
no building or other improvement on the Mortgaged Premises and constituting a
part thereof shall be materially altered, removed or demolished nor shall any
material fixtures or appliances on, in or about said 

                                      -11-
<PAGE>   12

buildings or improvements be severed, removed, sold or mortgaged, without the
consent of Beneficiary or the holder of the indebtedness hereby secured and in
the event of the demolition or destruction in whole or in material part of any
of the fixtures, chattels or similar articles of personal property covered
hereby, Grantor covenants that the same will be replaced promptly by similar
fixtures, chattels and articles of personal property at least equal in quality
and condition to those replaced (unless the Grantor, in the exercise of its
commercially reasonable judgment, deems it unnecessary to replace such
property), free from any security interest in or encumbrance thereon or
reservation of title thereto other than liens permitted by the Credit Agreement
and the Permitted Exceptions; provided, however, that Grantor may alter, remove
or demolish any such building, improvement, fixture or appliance, and need not
replace any such fixtures or personal property, in each case to the extent such
action (i) is desirable to the proper conduct of the business of Grantor in the
ordinary course as presently conducted and otherwise in the best interest of
Grantor, (ii) does not impair the overall value or utility of the Mortgaged
Premises and Grantor's other related properties as an integrated facility, (iii)
does not decrease the efficiency or capacity of the Mortgaged Premises and (iv)
does not impair the rights and benefits under this Deed of Trust of the Secured
Creditors. Grantor further agrees to permit, commit or suffer no material waste,
impairment or deterioration of the Mortgaged Premises or any part thereof; to
keep and maintain said Mortgaged Premises and every part thereof in good working
condition (ordinary wear and tear excepted); to effect such repairs as
Beneficiary or the holder of the indebtedness hereby secured may reasonably
require and from time to time to make all needful and proper replacements and
additions so that said buildings, fixtures, machinery and appurtenances will, at
all times, be in good working condition (ordinary wear and tear excepted), fit
and proper for the respective purposes for which they are being used by Grantor;
to comply with all statutes, orders, requirements or decrees relating to the
Mortgaged Premises by any Federal, State or municipal authority, noncompliance
with which could have a material adverse effect on the financial condition,
properties, business or operations of the Grantor; to observe and comply with
all conditions and requirements necessary to preserve and extend any and all
rights, licenses, permits (including, but not limited to, zoning variances,
special exceptions and non-conforming uses), privileges, franchises and
concessions which are applicable to the Mortgaged Premises or which have been
granted to or contracted for by Grantor in connection with any existing or
presently contemplated use of the Mortgaged Premises or any part thereof and
which are necessary in the operation of the Grantor's business and not to
initiate or acquiesce in any changes to or terminations of any of the foregoing
or of zoning classifications affecting the use to which the Mortgaged Premises
or any part thereof may be put and which are necessary in the operation of the
Grantor's business without the prior written consent of Beneficiary or the
holder of the indebtedness hereby secured; and to make no material alterations
in or improvements or additions to the Mortgaged Premises which would impair the
overall value or utility of the Mortgaged Premises and Grantor's other related
properties as an integrated facility or which would impair the rights and
benefits under this Deed of Trust of the Trustee or the holder of any
indebtedness hereby secured, except as required by governmental authority or
pursuant to the 

                                      -12-
<PAGE>   13

Credit Agreement or as permitted by Beneficiary or the holder of the
indebtedness hereby secured.

              Section 11. Liens and Encumbrances. Grantor covenants with Trustee
and Beneficiary that it is seized of the Mortgaged Premises in fee and has the
right to convey in fee simple; that the same are free and clear of all
encumbrances (except as set forth below) and that Grantor will warrant and
defend the said title against the claims of all persons whatsoever. Grantor will
not, without the prior written consent of Trustee or Beneficiary or the holder
of the indebtedness hereby secured, directly or indirectly, create or suffer to
be created or to remain and will discharge or promptly cause to be discharged
any mortgage, lien, encumbrance or charge on, pledge of, or conditional sale or
other title retention agreement with respect to, the Mortgaged Premises or any
part thereof, whether superior or subordinate to the lien hereof, except for
this instrument, liens permitted by the Credit Agreement and those exceptions to
title listed on Schedule II attached hereto (the "Permitted Exceptions").

              Section 12. Right of Trustee or Beneficiary to Perform Grantor's
Covenants, Etc. If Grantor shall fail to make any payment or perform any act
required to be made or performed hereunder, Trustee or Beneficiary or the holder
of the indebtedness hereby secured, without waiving or releasing any obligation
or default, may (but shall be under no obligation to) at any time thereafter and
upon giving written notice to Grantor of such failure, make such payment or
perform such act for the account and at the expense of Grantor, and may enter
upon the Mortgaged Premises or any part thereof for such purpose and take all
such action thereon as, in the opinion of Trustee or Beneficiary, may be
necessary or appropriate therefor. All sums so paid by Trustee or Beneficiary or
the holder of the indebtedness hereby secured and all costs and expenses
(including without limitation reasonable attorney's fees and expenses) so
incurred, together with interest thereon from the date of payment or incurrence
at the Default Rate shall constitute so much additional indebtedness hereby
secured and shall be paid by Grantor to Trustee or Beneficiary or the holder of
the indebtedness hereby secured on demand. Trustee or Beneficiary or the holder
of the indebtedness hereby secured in making any payment authorized under this
Section relating to taxes or assessments may do so according to any bill,
statement or estimate procured from the appropriate public office without
inquiry into the accuracy of such bill, statement or estimate or into the
validity of any tax assessment, sale, forfeiture, tax lien or title or claim
thereof. Trustee or Beneficiary or the holder of the indebtedness hereby
secured, in performing any act hereunder, shall be the sole judge of whether
Grantor is required to perform same under the terms of this Deed of Trust.

              Section 13. After-Acquired Property. Any and all property
hereafter acquired which is of the kind or nature herein provided, or intended
to be and become subject to the lien hereof, shall ipso facto, and without any
further conveyance, assignment or act on the part of Grantor, become and be
subject to the lien of this Deed of Trust as fully and completely as though

                                      -13-

<PAGE>   14

specifically described herein; but nevertheless Grantor shall from time to time,
if requested by Trustee or Beneficiary, execute and deliver any and all such
further assurances, conveyances and assignments as Trustee or Beneficiary may
reasonably require for the purpose of expressly and specifically subjecting to
the lien of this Deed of Trust all such property. Notwithstanding anything to
the contrary contained in this Deed of Trust, there shall not be subject to the
lien hereof any property hereafter acquired by Grantor which is of the kind or
nature herein provided which (a) is not a replacement of or substitute for
property subject to the lien hereof, and (b) is subject to a lien or security
interest that secures the purchase price, or indebtedness incurred to pay the
purchase price, thereof and that attaches to no other property of the Grantor.

              Section 14. Inspection by Trustee or Beneficiary. Trustee,
Beneficiary, the holder of the indebtedness hereby secured and any Secured
Creditor shall have the right to inspect the Mortgaged Premises upon reasonable
notice and during normal business hours, and access thereto shall be permitted
for that purpose provided, however, that prior to the occurrence of an event of
default hereunder any such access or inspection shall be during the Grantor's
normal business hours and upon reasonable notice to Grantor.

              Section 15. Financial Reports. Grantor will furnish to the
Trustee, Beneficiary, or any Lender such information and data with respect to
the financial condition, business affairs and operations of Grantor and the
Mortgaged Premises as may be required by the Credit Agreement.

              Section 16. Subrogation. Grantor acknowledges and agrees that
Trustee or Beneficiary or the holder of the indebtedness hereby secured shall be
subrogated to any lien discharged out of the proceeds of any drafts presented
under any Letter of Credit, the proceeds of any loans evidenced by the Notes or
out of any advance by Trustee or Beneficiary or the holder of the indebtedness
hereby secured hereunder, irrespective of whether or not any such lien may have
been released of record.

              Section 17. Events of Default. Any one or more of the following
shall constitute an event of default hereunder:

                   (a) Default for a period of five (5) days in the payment when
         due of (i) all or any part of the interest on any Note (whether at
         stated maturity or at any other time provided for in the Credit
         Agreement) or (ii) any obligation of the Grantor to reimburse the
         Beneficiary for any draft drawn under any Letter of Credit; or

                   (b) Default in the payment when due (whether by lapse of
         time, acceleration, or otherwise) of the principal of any of the Notes
         or of any other indebtedness hereby secured and the lapse of any period
         of grace expressly applicable to such default; or

                                      -14-
<PAGE>   15

                   (c) The Mortgaged Premises or any part thereof shall be sold,
         transferred, or conveyed, whether voluntarily or involuntarily, by
         operation of law or otherwise, except for (i) dispositions permitted by
         the Credit Agreement or any Collateral Document and (ii) sales of
         obsolete, worn out or unusable fixtures or personal property which are
         concurrently replaced (unless the Grantor, in the exercise of its
         commercially reasonable judgment deems such replacement unnecessary or
         impractical and such failure to replace would cause no material adverse
         change in the Mortgaged Premises) with similar fixtures or personal
         property at least equal in quality and condition to those sold and
         owned by Grantor free of any lien, charge or encumbrance other than the
         lien hereof and other liens permitted under the Credit Agreement; or

                   (d) The occurrence of any event or the existence of any
         condition in each case constituting an Event of Default under the
         Credit Agreement which is not cured within the applicable grace period,
         if any; or

                   (e) Any indebtedness secured by a lien or charge on the
         Mortgaged Premises or any part thereof is not paid when due after the
         expiration of applicable grace periods and the giving of applicable
         notices, if any, or proceedings are commenced to foreclose or otherwise
         realize upon any such lien or charge or to have a receiver appointed
         for the property subject thereto or to place the holder of such
         indebtedness or its representative in possession thereof; or

                   (f)     The Mortgaged Premises is abandoned.

              Section 18. Remedies. When any event of default has happened and
is continuing, regardless of the pendency of any proceeding which has or might
have the effect of preventing Grantor from complying with the terms of this
instrument and of the adequacy of the security for the Revolving Credit Notes,
and in addition to such other rights as may be available under applicable law,
but subject at all times to any mandatory legal requirements:

                   (a) Acceleration. Beneficiary may, by written notice to
         Grantor, declare the Revolving Credit Notes, the obligations of Grantor
         under the Credit Agreement and all unpaid indebtedness of Grantor
         hereby secured, including any interest then accrued thereon, to be
         forthwith due and payable, whereupon the same shall become and be
         forthwith due and payable, without other notice or demand of any kind.
         The foregoing right of acceleration is in addition to and not in
         substitution for any such rights which are available under the Credit
         Agreement or otherwise.

                   (b) Uniform Commercial Code. Trustee or Beneficiary shall,
         with respect to any part of the Mortgaged Premises constituting
         property of the type in respect of which 


                                      -15-
<PAGE>   16

         realization on a lien or security interest granted therein is governed
         by the Uniform Commercial Code, have all the rights, options and
         remedies of a secured party under the Uniform Commercial Code of North
         Carolina, including without limitation, the right to the possession of
         any such property, or any part thereof, and the right to enter without
         legal process any premises where any such property may be found. Any
         requirement of said Code for reasonable notification shall be met by
         mailing written notice to Grantor at its address above set forth at
         least 10 days prior to the sale or other event for which such notice is
         required. The expenses of retaking, selling, and otherwise disposing of
         said property, including reasonable attorney's fees and legal expenses
         incurred in connection therewith, shall constitute so much additional
         indebtedness hereby secured and shall be payable upon demand with
         interest at the Default Rate.

                   (c) Foreclosure. Trustee or Beneficiary may proceed to
         protect and enforce the rights of Trustee or Beneficiary hereunder (i)
         by any action at law, suit in equity or other appropriate proceedings,
         whether for the specific performance of any agreement contained herein,
         or for an injunction against the violation of any of the terms hereof,
         or in aid of the exercise of any power granted hereby or by law, or
         (ii) by the foreclosure of or other sale proceeding under this Deed of
         Trust.

                   (d) Appointment of Receiver. Trustee or Beneficiary shall, as
         a matter of right, without notice and without giving bond to Grantor or
         anyone claiming by, under or through it, and without regard to the
         solvency or insolvency of Grantor or the then value of the Mortgaged
         Premises, be entitled to have a receiver appointed of all or any part
         of the Mortgaged Premises and the rents, issues and profits thereof,
         with such power as the court making such appointment shall confer, and
         Grantor hereby consents to the appointment of such receiver and shall
         not oppose any such appointment. Any such receiver may, to the extent
         permitted under applicable law, without notice, enter upon and take
         possession of the Mortgaged Premises or any part thereof by force,
         summary proceedings, ejectment or otherwise, and may remove Grantor or
         other persons and any and all property therefrom, and may hold, operate
         and manage the same and receive all earnings, income, rents, issues and
         proceeds accruing with respect thereto or any part thereof, whether
         during the pendency of any foreclosure or until any right of redemption
         shall expire or otherwise.

                   (e) Taking Possession, Collecting Rents, Etc. Trustee or
         Beneficiary may enter and take possession of the Mortgaged Premises or
         any part thereof and manage, operate, insure, repair and improve the
         same and take any action which, in Trustee's or Beneficiary's judgment,
         is necessary or proper to conserve the value of the Mortgaged Premises.
         Trustee or Beneficiary may also take possession of, and for these
         purposes use, any and all personal property contained in the Mortgaged
         Premises and in which a lien is 


                                      -17-
<PAGE>   17

         granted hereby and used in the operation, rental or leasing thereof or
         any part thereof. Trustee or Beneficiary shall be entitled to collect
         and receive all earnings, revenues, rents, issues and profits of the
         Mortgaged Premises or any part thereof (and for such purpose Grantor
         does hereby irrevocably constitute and appoint Trustee or Beneficiary
         its true and lawful attorney-in-fact for it and in its name, place and
         stead to receive, collect and receipt for all of the foregoing, Grantor
         irrevocably acknowledging that any payment made to Trustee or
         Beneficiary hereunder shall be a good receipt and acquittance against
         Grantor to the extent so made) and to apply same to the reduction of
         the indebtedness hereby secured. The right to enter and take possession
         of the Mortgaged Premises and use any personal property therein, to
         manage, operate and conserve the same, and to collect the rents, issues
         and profits thereof, shall be in addition to all other rights or
         remedies of Trustee or Beneficiary hereunder or afforded by law, and
         may be exercised concurrently therewith or independently thereof. The
         expenses (including any receiver's fees, counsel fees, costs and
         agent's compensation) incurred pursuant to the powers herein contained
         shall be so much additional indebtedness hereby secured which Grantor
         promises to pay upon demand together with interest at the Default Rate.
         Trustee or Beneficiary shall not be liable to account to Grantor for
         any action taken pursuant hereto other than to account for any rents
         actually received by Trustee or Beneficiary. Without taking possession
         of the Mortgaged Premises, Trustee or Beneficiary may, in the event the
         Mortgaged Premises becomes vacant or is abandoned, take such steps as
         it deems appropriate to protect and secure the Mortgaged Premises
         (including hiring watchmen therefor) and all costs incurred in so doing
         shall constitute so much additional indebtedness hereby secured payable
         upon demand with interest thereon at the Default Rate.

                   (f) After the occurrence of an event of default, and on the
         application of the Beneficiary it shall be lawful for and the duty of
         the Trustee, and he is hereby authorized and empowered to expose to
         sale and to sell the Mortgaged Premises at public auction for cash,
         after having first complied with all applicable requirements of North
         Carolina law with respect to the exercise of powers of sale contained
         in deeds of trust and upon such sale, the Trustee shall convey title to
         the purchase in fee simple. After retaining from the proceeds of such
         sale a commission for his services and all expense incurred by him,
         including reasonable attorney's fees for legal services actually
         performed, the Trustee shall apply the residue of the proceeds, first
         to the payment of all sums expended by the Beneficiary under the terms
         of this Deed of Trust; second, to the payment of the Note and interest
         thereon; and the balance, if any, shall be paid to the Grantor or other
         person lawfully entitled thereto. The Grantor agrees that in the event
         of a sale hereunder, the Beneficiary shall have the right to bid at
         such sale. The Trustee may require the successful bidder at any sale to
         deposit immediately with the Trustee cash or certified check in an
         amount up to twenty-five percent (25%) of the bid, provided notice of
         such 


                                      -17-
<PAGE>   18

         requirement is contained in the advertisement of the sale. The bid may
         be rejected if the deposit is not immediately made and thereupon the
         next highest bidder may be declared to be the purchaser. Such deposit
         shall be refunded in case a resale is had; otherwise it shall be
         applied to the purchase price. If personal property is sold hereunder,
         it need not be at the place of sale. The published notice, however,
         shall state the time and place where such personal property may be
         inspected prior to sale. The Trustee's commission shall be five percent
         (5%) of the gross proceeds of the sale or five hundred dollars
         ($500.00), whichever is greater, for a completed foreclosure. In the
         event foreclosure is commenced, but not completed, the Grantor shall
         pay all expenses incurred by the Trustee, including reasonable
         attorneys' fees, and a partial commission computed on five percent (5%)
         of the outstanding indebtedness or five hundred dollars ($500.00),
         whichever is greater, in accordance with the following schedule:
         one-fourth (1/4th) thereof before the Trustee issues a notice of
         hearing on the right to foreclose; one-half (1/2) thereof after
         issuance of said notice, three fourths (3/4ths) thereof after such
         hearing; and the greater of the full commission or minimum sum after
         the initial sale.

              Section 19. Waiver of Right to Redeem From Sale - Waiver of
Appraisement, Valuation, Etc. Grantor shall not and will not apply for or avail
itself of any appraisement, valuation, stay, extension or exemption laws, or any
so-called "Moratorium Laws", now existing or hereafter enacted in order to
prevent or hinder the enforcement or foreclosure of this Deed of Trust, but
hereby waives the benefit of such laws, to the extent provided by applicable
law. Grantor for itself and all who may claim through or under it waives any and
all right to have the property and estates comprising the Mortgaged Premises
marshalled upon any foreclosure of the lien hereof and agrees that any court
having jurisdiction to foreclose such lien may order the Mortgaged Premises sold
as an entirety. In the event of any sale made under or by virtue of this
instrument, the whole of the Mortgaged Premises may be sold in one parcel as an
entirety or in separate lots or parcels at the same or different times, all as
the Trustee or Beneficiary may determine. Beneficiary and/or any Secured
Creditor shall have the right to become the purchaser at any sale made under or
by virtue of this instrument and Beneficiary and/or any Secured Creditor so
purchasing at any such sale shall have the right to be credited upon the amount
of the bid made therefor by Beneficiary and/or any Secured Creditor with the
amount payable to Beneficiary or such Secured Creditor, as the case may be, out
of the net proceeds of such sale. In the event of any such sale, the Revolving
Credit Notes, Grantor's obligation under the Credit Agreement and the other
indebtedness hereby secured, if not previously due, shall be and become
immediately due and payable without demand or notice of any kind. Grantor hereby
waives any and all rights of redemption from sale under any order or decree of
foreclosure pursuant to rights herein granted, on behalf of Grantor, and each
and every person acquiring any interest in, or title to the Mortgaged Premises
described herein subsequent to the date of this Deed of Trust, and on behalf of
all other persons to the extent permitted by applicable law.

                                      -18-
<PAGE>   19

              Section 20. Costs and Expenses of Foreclosure. In any suit to
foreclose the lien hereof or in connection with any sale pursuant to powers
herein or by applicable law granted, there shall be allowed and included as
additional indebtedness in the decree for sale all expenditures and expenses
which may be paid or incurred by or on behalf of Trustee, Beneficiary and/or any
Secured Creditor for reasonable attorney's fees, outside appraiser's fees,
outlays for documentary and expert evidence, outside stenographic charges,
publication costs and costs (which may be estimated as the items to be expended
after the entry of the decree) of procuring all such abstracts of title, title
searches and examination, guarantee policies, and similar data and assurances
with respect to title as Trustee or Beneficiary may deem to be reasonably
necessary either to prosecute any foreclosure action or to evidence to the
bidder at any sale pursuant thereto the true condition of the title to or the
value of the Mortgaged Premises, all of which expenditures shall become so much
additional indebtedness hereby secured which Grantor agrees to pay and all of
such shall be immediately due and payable with interest thereon from the date of
expenditure until paid at the Default Rate.

              Section 2l. Application of Proceeds. Except as provided in Section
18(g), the proceeds of any foreclosure or other sale of the Mortgaged Premises,
including any sale of property pursuant to Section 18(b) hereof, shall be
distributed as set forth in Section 3.5 of the Credit Agreement. Grantor shall
remain liable to Trustee and the Beneficiary for any deficiency. Any surplus
remaining after the full payment and satisfaction of the foregoing shall be
returned to Grantor or to whomsoever a court of competent jurisdiction shall
determine to be entitled thereto. If the Hedging Liability has not become firm,
an amount equal to the amount thereof shall be held by Beneficiary unless and
until the same becomes due and then applied to the payment of same.

              Section 22. Deficiency Decree. If at any foreclosure proceeding
the Mortgaged Premises shall be sold for a sum less than the total amount of
indebtedness for which judgment is therein given, the judgment creditor shall be
entitled to the entry of a deficiency decree against Grantor and against the
property of Grantor for the amount of such deficiency; and Grantor does hereby
irrevocably consent to the appointment of a receiver for the Mortgaged Premises
and the property of Grantor and of the rents, issues and profits thereof after
such sale and until such deficiency decree is satisfied in full.

              Section 23. Trustee, Beneficiary's and Secured Creditors' Remedies
Cumulative - No Waiver. No remedy or right of Trustee, Beneficiary, any Secured
Creditor or the holder of the indebtedness hereby secured shall be exclusive of
but shall be cumulative and in addition to every other remedy or right now or
hereafter existing at law or in equity or by statute or otherwise. No delay in
the exercise or omission to exercise any remedy or right accruing on any default
shall impair any such remedy or right or be construed to be a waiver of any such
default or acquiescence therein, nor shall it affect any subsequent default of
the same or a different 

                                      -19-
<PAGE>   20

nature. Every such remedy or right may be exercised concurrently or
independently, and when and as often as may be deemed expedient by Trustee,
Beneficiary, any Secured Creditor or the holder of the indebtedness hereby
secured.

              Section 24. Trustee and Beneficiary Party to Suits. If Trustee,
Beneficiary or any holder of the indebtedness hereby secured shall be made a
party to or shall intervene in any action or proceeding affecting the Mortgaged
Premises or the title thereto or the interest of Trustee, Beneficiary or any
holder of the indebtedness hereby secured under this Deed of Trust (including
probate and bankruptcy proceedings), or if Trustee, Beneficiary or any holder of
the indebtedness hereby secured employs an attorney to collect any or all of the
indebtedness hereby secured or to enforce any of the terms hereof or realize
hereupon or to protect the lien hereof, or if Trustee, Beneficiary or any holder
of the indebtedness hereby secured shall incur any costs or expenses in
preparation for the commencement of any foreclosure proceedings or for the
defense of any threatened suit or proceeding which might affect the Mortgaged
Premises or the security hereof, whether or not any such foreclosure or other
suit or proceeding shall be actually commenced, then in any such case, Grantor
agrees to pay to Trustee, Beneficiary or any holder of the indebtedness hereby
secured, immediately and without demand, all reasonable costs, charges, expenses
and attorney's fees incurred by Trustee, Beneficiary or any holder of the
indebtedness hereby secured in any such case, and the same shall constitute so
much additional indebtedness hereby secured payable upon demand with interest at
the Default Rate from the time of expenditure.

              Section 25. Modifications Not to Affect Lien. Trustee and
Beneficiary, without notice to anyone (except the Lenders), and without regard
to the consideration, if any, paid therefor, or the presence of other liens on
the Mortgaged Premises, may in its discretion, in the case of the Trustee, or at
the discretion of the Lenders required to consent thereto by the terms of the
Credit Agreement, in the case of the Beneficiary, release any part of the
Mortgaged Premises or any person liable for any of the indebtedness hereby
secured, may extend the time of payment of any of the indebtedness hereby
secured and may grant waivers or other indulgences with respect hereto and
thereto, and may agree with Grantor to modifications to the terms and conditions
contained herein or otherwise applicable to any of the indebtedness hereby
secured (including modifications in the rates of interest applicable thereto),
without in any way affecting or impairing the liability of any party liable upon
any of the indebtedness hereby secured or the priority of the lien of this Deed
of Trust upon all of the Mortgaged Premises not expressly released, and any
party acquiring any direct or indirect interest in the Mortgaged Premises shall
take same subject to all of the provisions hereof.

              Section 26. Compliance with Environmental Laws. Grantor represents
and warrants that, to the best of Grantor's knowledge, after due inquiry, and
except to the extent disclosed in the Phase I Environmental Site Assessment
Update dated March 12, 1998, prepared by Trizon

extent that no applicable Governmental Regulations were, are or will be violated
in connection therewith: it has never in the past engaged in, and agrees that in
the future it shall not conduct, any business, operations or activity on the
Mortgaged Premises, or employ or use the personal property or facilities, to
manufacture, use, generate, treat, store, transport or dispose of any hazardous
substance (including, without limitation, petroleum, its derivatives or
by-products, or other hydrocarbons), or any other substance (collectively
"Hazardous Materials") which is prohibited, controlled or regulated under
applicable law, or which poses a threat or nuisance to safety, health or the
environment, including, without limitation, any business, operation or activity
which would bring Grantor, its property or facilities, within the ambit of the
Resource Conservation and Recovery Act of 1976, as amended by the Solid and
Hazardous Waste Amendments of 1984, 42 U.S.C. SS.6901 et seq., the Comprehensive
Environmental Response, Compensation and Liability Act of 1980, as amended by
the Superfund Amendments and Reauthorization Act of 1986, 42 U.S.C. SS.9601 et
seq., the Clean Air Act of 1966, as amended, 42 U.S.C. SS.7401 et seq., or any
similar state, county, regional or local statute, law, regulation, rule or
ordinance, including, without limitation, any state statute providing for
financial responsibility for cleanup for the release or threatened release of
substances provided for thereunder. Grantor agrees to diligently pursue
remediation of any condition which would violate or violates any Governmental
Regulation or which is likely to result in the creation or imposition of
liability on Grantor thereunder, and to in any event complete the remediation of
each of such prior to the time that the same has a material adverse impact on
the financial condition of the Grantor or materially interferes with the use and
operation of the Mortgaged Premises for its intended purposes.

              Section 30. Liens Absolute, Etc. The Grantor acknowledges and
agrees that the liens and security interests hereby created are absolute and
unconditional and shall not in any manner be affected or impaired by any acts or
omissions whatsoever of the Trustee or the Beneficiary or any other holders of
any of the indebtedness hereby secured, and without limiting the generality of
the foregoing, the lien and security hereof shall not be impaired by any
acceptance by the Trustee or the Beneficiary or any other holder of any of the
indebtedness hereby secured of any other security for or guarantors upon any of
the indebtedness hereby secured or by any failure, neglect or omission on the
part of the Trustee or the Beneficiary or any other holder of any of the
indebtedness hereby secured to realize upon or protect any of the indebtedness
hereby secured or any collateral security therefor. The lien and security hereof
shall not in any manner be impaired or affected by any sale, pledge, surrender,
compromise, settlement, release, renewal, extension, indulgence, alteration,
substitution, exchange, change in, modification or disposition of any of the
indebtedness hereby secured, or of any collateral security therefor, or of any
guaranty thereof, or of any loan agreement executed in connection therewith. In
order to realize hereon and to exercise the rights granted Trustee and/or
Beneficiary hereby and under applicable law, there shall be no obligation on the
part of Trustee or the Beneficiary or any other holder of any of the
indebtedness hereby secured at any time to first resort for payment to the
obligor on any note evidencing any of the indebtedness hereby secured or to any
guaranty of any of the indebtedness hereby secured or any part thereof or to
resort to any other collateral security, property, liens or any other rights or
remedies whatsoever, and Beneficiary shall have the right to enforce this
instrument irrespective of whether or not other proceedings or steps are pending
seeking resort to or realization upon or from any of the foregoing are pending.

              Section 31. Notice of Environmental Problem. Except as heretofore
disclosed in writing to the Beneficiary, Grantor represents and warrants that to
the best of its knowledge it has not given, nor should it give, nor has it
received, any notice, letter, citation, order, warning, complaint, inquiry,
claim or demand that: (i) Grantor has violated, or is about to violate, any
federal, state, regional, county or local environmental, health or safety
statute, law, rule, regulation, ordinance, judgment or order on the Mortgaged
Premises; (ii) there has been a release, or there is threat of release, of
hazardous substances (including, without limitation, petroleum, its by-products
or derivatives, or other hydrocarbons) from the Mortgaged Premises; (iii)
Grantor may be or is liable, in whole or in part, for the costs or cleaning up,
remediating or responding to a release of hazardous substances (including,
without limitation, petroleum, its by-products or derivatives, or other
hydrocarbons) on the Mortgaged Premises; (iv) any of the Grantor's property or
assets are subject to a lien in favor of any governmental body for any
liability, costs or damages, under federal, state or local environmental law,
rule or regulation arising from or costs incurred by such governmental entity in
response to a release of a hazardous substance (including, without limitation,
petroleum, its by-products or derivatives, or other hydrocarbons). In the event
that Grantor receives any notice of the type described in this 

                                      -23-
<PAGE>   24

Section, Grantor shall promptly provide a copy to Beneficiary, and in no event,
later than fifteen (15) days from Grantor's receipt or submission thereof.

              Section 32. Direct and Primary Security - No Subrogation. The lien
and security herein created and provided for stands as direct and primary
security for the Notes and the Applications as well as for any of the other
indebtedness hereby secured. No application of any sums received by the Trustee
or the Beneficiary in respect of the Mortgaged Premises or any disposition
thereof to the reduction of the indebtedness hereby secured or any part thereof
shall in any manner entitle Grantor to any right, title or interest in or to the
indebtedness hereby secured or any collateral security therefor, whether by
subrogation or otherwise, unless and until all indebtedness hereby secured has
been fully paid and satisfied.

              Section 33. Notices. All communications provided for herein shall
be in writing and shall be deemed to have been given when delivered personally
or mailed by first class mail, postage prepaid, addressed to the parties hereto
at their addresses as shown at the beginning of this Deed of Trust or to such
other and different address as Grantor, Trustee, Beneficiary and Secured
Creditors may designate pursuant to a written notice sent in accordance with the
provisions of this Section 33; provided that notice of a default hereunder shall
be deemed to have been given or made when actually received by Grantor by
certified mail, telex, telecopier, or other facsimile communication method.

              Section 34. Partial Invalidity. All rights, powers and remedies
provided herein are intended to be limited to the extent necessary so that they
will not render this Deed of Trust invalid, unenforceable or not entitled to be
recorded, registered or filed under any applicable law. If any term of this Deed
of Trust shall be held to be invalid, illegal or unenforceable, the validity and
enforceability of the other terms of this Deed of Trust shall in no way be
affected thereby.

              Section 35. Successors and Assigns. Whenever any of the parties
hereto is referred to, such reference shall be deemed to include the successors
and assigns of such party; and all the covenants, promises and agreements in
this Deed of Trust contained by or on behalf of Grantor, or by or on behalf of
Trustee and Beneficiary, shall bind and inure to the benefit of the respective
successors and assigns of such parties, whether so expressed or not. If more
than one party signs this instrument as Grantor, then the term "Grantor" as used
herein shall mean all of such parties, jointly and severally.

              Section 36 Headings. The headings in this instrument are for
convenience of reference only and shall not limit or otherwise affect the
meaning of any provision hereof.

              Section 37. Changes, Etc. This instrument and the provisions
hereof may be changed, waived, discharged or terminated only by an instrument in
writing signed by the party against which enforcement of the change, waiver,
discharge or termination is sought.

              Section 38. Future Advances and Revolving Credit Loan. This Deed
of Trust is given to secure present and future obligations of Grantor to
Beneficiary, and this Deed of Trust is executed to secure all such obligations.
The period in which future obligations may be incurred and secured by this Deed
of trust is the period within 10 years from the date hereof; provided, however,
that said period may be extended by Beneficiary up to but not more than 15 years
from the date hereof. The amount of present obligations secured by this Deed of
Trust is Ninety Million Dollars ($90,000,000), and the maximum principal amount,
including present and future obligations, which may be secured by this Deed of
Trust at any one time is One Hundred Eighty Million Dollars ($180,000,000). Any
additional amounts advanced by Beneficiary pursuant to the provisions of this
Deed of Trust shall be deemed necessary expenditures for the protection of the
security. Each future advance need not be evidenced by a written instrument or
notation signed by Grantor stipulating that such advance is secured by this Deed
of Trust. All future obligations shall be considered to be made pursuant to the
requirements of North Carolina General Statutes Section 45-67, et seq., or any
amendments thereto. Subject to the terms and provisions of the Credit Agreement,
the principal amount of the Revolving Credit Notes may be borrowed, repaid and
reborrowed again, from time to time, on a revolving basis, provided that the
maximum principal amount of obligations outstanding at any one time and secured
hereby shall not exceed the maximum principal amount set forth above.

              Section 39. Demand Nature of Indebtedness. Nothing herein
contained shall be deemed to affect or impair the demand character of any of the
indebtedness hereby secured which is payable upon demand and payment thereof may
be demanded irrespective of whether or not the Grantor is in compliance with the
terms hereof and that upon doing so Trustee and Beneficiary shall be entitled to
invoke the remedies upon default herein and by applicable law provided for.

              Section 40. Multisite Real Estate Transaction. Grantor
acknowledges that this Deed of Trust is one of a number of other mortgages and
deeds of trusts and other security documents dated of even date herewith (such
mortgages, deeds of trust and other security documents dated of even date
herewith and any supplements or amendments thereto and any other mortgages,
deeds of trust or security documents securing the indebtedness hereby secured
are collectively called the "Other Mortgages") which secure the indebtedness
hereby secured. Grantor agrees that the lien of this Deed of Trust shall be
absolute and unconditional and shall not in any manner be affected or impaired
by any acts or omissions whatsoever of Trustee or Beneficiary and, without
limiting the generality of the foregoing, the lien hereof shall not be impaired
by any acceptance by Trustee or Beneficiary of any security for or guarantors
upon any of the 

                                      -25-
<PAGE>   26

indebtedness hereby secured, or by any failure, neglect or omission on the part
of the Trustee or Beneficiary to realize upon or protect any of the indebtedness
hereby secured or any collateral security therefor including the Other
Mortgages. The lien hereof shall not in any manner be impaired or affected by
any release (except as to the property released) sale, pledge, surrender,
compromise, settlement, renewal, extension, indulgence, alteration, changing,
modification or disposition of any of the indebtedness hereby secured or of any
of the collateral security therefor, including without limitation the Other
Mortgages or of any guarantee thereof, and Beneficiary may at its discretion
foreclose, exercise any power of sale, or exercise any other remedy available to
it under any or all of the Other Mortgages without first exercising or enforcing
any of its rights and remedies hereunder. Such exercise of Beneficiary's rights
and remedies under any or all of the Other Mortgages shall not in any manner
impair the indebtedness hereby secured or the lien of this Deed of Trust and any
exercise of the rights or remedies of Beneficiary or Trustee hereunder shall not
impair the lien of any of the Other Mortgages or any of Beneficiary's rights and
remedies thereunder. The undersigned specifically consents and agrees that
Beneficiary may exercise its rights and remedies hereunder and under the Other
Mortgages separately or concurrently and in any order that it may deem
appropriate.

              Section 41. Default Rate. As used herein, the term "Default Rate"
shall mean the rate per annum set forth in Section 2.1 of the Credit Agreement.

              Section 42. Agent. Beneficiary has been appointed as agent
pursuant to the Credit Agreement. In acting under or by virtue of this Deed of
Trust, Beneficiary shall be entitled to all the rights, authority, privileges
and immunities provided in Section 10 of the Credit Agreement, all of which
provisions of said Section 10 are incorporated by reference herein with the same
force and effect as if set forth herein. Beneficiary hereby disclaims any
representation or warranty to Secured Creditors concerning the perfection of the
security interest granted hereunder or the value of the Mortgaged Premises.

              Section 43. Substitute Trustee. Trustee, or any substitute
Trustee, may be removed at any time with or without cause, at the option of
Harris Trust and Savings Bank, by written declaration of such removal signed by
Harris Trust and Savings Bank, without any notice to or demand upon Trustee or
substitute Trustee so removed, or Grantor or any other person. If at any time
Trustee or any substitute Trustee should be so removed, die or refuse, fail or
be unable to act as such Trustee or substitute Trustee, Harris Trust and Savings
Bank may appoint any person, including itself, as substitute Trustee hereunder,
without any formality other than a written declaration of such appointment
executed by Harris Trust and Savings Bank; and immediately upon such
appointment, the substitute Trustee so appointed shall automatically become
vested with all the estate and title in the Mortgaged Premises, and with all of
the rights, powers, privileges, authority, options and discretions, and charged
with all of the duties and liabilities, vested in or imposed upon Trustee by
this Deed of Trust, and any conveyance executed by such 


                                      -26-
<PAGE>   27

substitute Trustee, including the recitals therein contained, shall have the
same effect and validity as if executed by Trustee.

              Section 44. Environmental Indemnity. Grantor hereby agrees to
indemnify Trustee and Beneficiary and hold Beneficiary harmless from and against
any and all claims, losses, damages, liabilities, fines, penalties, charges,
administrative and judicial proceedings and orders, judgments, remedial action
requirements, enforcement actions of any kind, and all costs and expenses (other
than any of the foregoing resulting in whole or in part from acts or omissions
of Trustee or Beneficiary or from Beneficiary's or Trustee's gross negligence or
wilful misconduct) incurred in connection therewith (including but not limited
to reasonable outside attorneys' fees, paralegal charges and expenses), arising
directly or indirectly, whole or in part, out of (a) the presence on or under
the Mortgaged Premises of any Hazardous Materials or releases or discharges of
Hazardous Materials on, under or from the Mortgaged Premises, (b) any activity
carried on or undertaken on or off the Mortgaged Premises, whether prior to or
during the term of this Deed of Trust, and whether by Grantor or any predecessor
in title or any employees, agents, contractors or subcontractors of Grantor or
any predecessor in title, or third persons at any time occupying or present on
the Mortgaged Premises in connection with the treatment, decontamination,
handling, removal, storage, clean-up, transport or disposal of any Hazardous
Materials at any time located or present on or under the Mortgaged Premises; and
(c) any breach of the covenants contained in this Section. The foregoing
indemnity shall further apply to any residual contamination on or under the
Mortgaged Premises or affecting any natural resources, any contamination of any
property or natural resources arising in connection with the generation, use,
handling, storage, transport or disposal of any such Hazardous Materials, and
irrespective of whether any such activities were or will be undertaken in
accordance with applicable laws, regulations, codes and ordinances. The
obligation of Grantor to indemnify and hold harmless under this Section shall
survive any foreclosure of this Deed of Trust or any transfer of the Mortgaged
Premises by deed in lieu of foreclosure or upon the exercise of the power of
sale contained herein.

              Section 45. Restrictions on Secured Creditor's Right to Enforce.
No Secured Creditor shall have the right to institute any suit, action or
proceeding in equity or at law for the foreclosure of this Deed of Trust or for
the execution of any trust or power hereof or for the appointment of a receiver,
or for the enforcement of any other remedy under or upon this Deed of Trust; it
being understood and intended that no one or more of the Secured Creditors shall
have any right in any manner whatsoever to affect, disturb or prejudice the lien
of this Deed of Trust by its or their action or to enforce any right hereunder,
and that all proceedings at law or in equity shall be instituted, had and
maintained by the Beneficiary in the manner herein provided and for the ratable
benefit of the Secured Creditors .

              Section 46. Governing Law. The creation of the Deed of Trust, the
perfection of the lien or security interest in the Mortgaged Premises, and the
rights and remedies of Grantor, Trustee and Beneficiary with respect to the
Mortgaged Premises, as provided herein and by the laws of the state in which the
Mortgaged Premises is located, shall be governed by and construed in accordance

in accordance with the internal laws of the State of Illinois without regard to
principles of conflicts of laws, such state being the state where such documents
were deemed to be executed and delivered.

              Section 47. Acceptance of Trust. Trustee accepts this Trust when
this Deed of Trust, duly executed and acknowledged, is made a public record as
provided by law. Trustee is not obligated to notify any party hereto of pending

Beneficiary, or Trustee shall be a party, unless brought by Trustee.

              Section 48. No Liability on Trustee. Notwithstanding anything
contained herein, this Deed of Trust is only intended as security for the
indebtedness hereby secured, and Trustee shall not be obligated to perform or
discharge, and does not hereby undertake to perform or discharge, any
obligation, duty or liability of Grantor with respect to any of the Mortgaged
Premises. Except for its gross negligence or willful and wanton misconduct, no
liability shall be enforced or asserted against Trustee in its exercise of the
powers herein respectively granted to it, and Grantor expressly waives and
releases any such liability. Grantor shall and does hereby agree to indemnify
and hold Trustee harmless of and from any and all liability, loss or damage
which it may or might incur under or by reason of the exercise of its rights
hereunder and of and from any and all claims and demands whatsoever which may be
asserted against it by reason of any alleged obligations or undertakings on its
part to perform or discharge any of the terms, covenants or agreements of
Grantor contained herein or with respect to any of the Mortgaged Premises,
except in the case of actions by the Trustee that constitute gross negligence or
willful misconduct. Trustee shall have no responsibility for the control, care,
management or repair of the Mortgaged Premises, nor shall it be responsible or
liable for any negligence in the management, operation, upkeep, repair or
control of the Mortgaged Premises resulting in loss or injury or death to any
licensee, employee, tenant or stranger. Without limiting the foregoing, Trustee
shall not be responsible for any recitals herein or for insuring the Mortgaged
Premises, or for the recording, filing or refiling of this Deed of Trust; nor
shall the Trustee be bound to ascertain or inquire as to the performance or
observance of any covenants, conditions or agreements on the part of the Grantor
contained herein.

                     AMENDED AND RESTATED SECURITY AGREEMENT


            This Amended and Restated Security Agreement (the "Agreement") is
dated as of May ___, 1998, by and among the parties executing this Agreement
under the heading "Debtors" (such parties, along with any parties who execute
and deliver to the Agent an agreement in the form attached hereto as Exhibit D,
being hereinafter referred to collectively as the "Debtors" and individually as
a "Debtor"), and HARRIS TRUST AND SAVINGS BANK, an Illinois banking corporation
("Harris"), with its mailing address at 111 West Monroe Street, Chicago,
Illinois 60603, acting as agent hereunder for the Secured Creditors hereinafter
identified and defined (Harris acting as such agent and any successor or
successors to Harris acting in such capacity being hereinafter referred to as
the "Agent");


                             PRELIMINARY STATEMENTS

            A. Morton Industrial Group, Inc., a Georgia corporation (the
"Company"), and certain subsidiaries of the Company, Harris, individually and as
agent, and certain lenders are currently party to a Credit Agreement dated as of
January 20, 1998 (such Credit Agreement, as the same may have been amended or
modified from time to time, including amendments and restatements thereof in its
entirety, being hereinafter referred to as the "Prior Credit Agreement"),
pursuant to which Harris and other lenders from time to time party to the Prior
Credit Agreement agreed, subject to certain terms and conditions, to extend
credit and make certain other financial accommodations available to the
"Borrowers" identified therein.

            B. The Company and certain subsidiaries of the Company are currently
party to a Security Agreement dated as of January 20, 1998, with Harris,
individually and as agent for the lenders party to the Prior Credit Agreement
(the "Prior Security Agreement"), pursuant to which the Company and such other
subsidiaries have granted liens on certain personal property as collateral
security for the indebtedness, obligations, and liabilities of the "Borrowers"
owing to such lenders under the Prior Credit Agreement.

            C. Concurrently herewith, Harris and the other lenders party to the
Prior Credit Agreement are refinancing all indebtedness, obligations, and
liabilities owed to such lenders by the "Borrowers" under the Prior Credit
Agreement (the "Prior Obligations").

            D. The Company and Harris, individually and as Agent, have also
entered into a Credit Agreement dated of even date herewith (such Credit
Agreement, as the same may be amended or modified from time to time, including
amendments and restatements thereof in its entirety, being hereinafter referred
to as the "Credit Agreement") pursuant to which Harris and other lenders which



<PAGE>   2

from time to time become party thereto (Harris and such other lenders which from
time to time become party thereto being hereinafter referred to collectively as
the "Lenders" and individually as a "Lender") have agreed to modify the terms
and conditions applicable to the Prior Obligations and to provide for additional
credit and financial accommodations to be made available to the Company
thereunder, all subject to the terms and conditions therein set forth.

            E. The Company may from time to time enter into one or more interest
rate exchange, cap, collar, floor or other agreements with one or more of the
Lenders party to the Credit Agreement, or their affiliates, for the purpose of
hedging or otherwise protecting the Company against changes in interest rates
(the liability of the Company in respect of such agreements with such Lenders
and their affiliates being hereinafter referred to as the "Hedging Liability")
(the affiliates of the Lenders to which any Hedging Liability is owed, together
with the Lenders and the Agent, being collectively referred to herein as the
"Secured Creditors").

            F. As a condition precedent to extending credit or otherwise making
financial accommodations available to the Company under the Credit Agreement,
the Lenders have required, among other things, that each Debtor grant to the
Agent for the benefit of the Secured Creditors a lien on and security interest
in certain personal property of such Debtor pursuant to this Agreement.

            G. The Company owns, directly or indirectly, all or substantially
all of the equity interests in each Debtor (other than the Company) and the
Company provides each Debtor with financial, management, administrative, and
technical support which enables such Debtor to conduct its business in an
orderly and efficient manner in the ordinary course.

            H. Each Debtor will benefit, directly or indirectly, from credit and
other financial accommodations extended by the Secured Creditors to the Company.

            NOW, THEREFORE, for and in consideration of the execution and
delivery by the Lenders of the Credit Agreement, and other good and valuable
consideration, receipt whereof is hereby acknowledged, the parties hereto hereby
agree as follows:

               Section 1. Terms Defined in Credit Agreement. All capitalized
terms used herein without definition shall have the same meanings herein as
such terms have in the Credit Agreement. The term "Debtor" and "Debtors" as
used herein shall mean and include the Debtors collectively and also each
individually, with all grants, representations,  warranties  and  covenants  of
and by the Debtors,  or any of them,  herein contained to constitute  joint and
several grants,  representations,  warranties and covenants of and by the
Debtors; provided,  however, that unless the context in which the same is used
shall otherwise  require,  any grant,  representation,

                                     -2-
<PAGE>   3

warranty or covenant contained herein related to the Collateral shall be made by
each Debtor only with respect to the  Collateral  owned by it or  represented by
such Debtor as owned by it.

               Section 2. Grant of Security Interest in the Collateral;
Obligations Secured. (a) Each Debtor hereby grants to the Agent for the benefit
of the Secured Creditors a lien on and security interest in, and right of
set-off against, and acknowledges and agrees that the Agent has and shall

                (viii) Accessions and Additions. All accessions and additions to

         foregoing and all insurance of the foregoing and proceeds thereof,

           (b) This Agreement is made and given to secure, and shall secure, the
payment and performance of (i) (x) any and all indebtedness, obligations and
liabilities of the Company to the Agent, the Lenders, or any of them
individually, evidenced by or otherwise arising out of or relating to the Credit
Agreement or any promissory note of the Company issued at any time under the
Credit Agreement (including all notes issued in extension or renewal thereof or
in substitution or replacement therefor), and (y) any liability of any of the
Debtors, or any of them individually, arising out of the Credit Agreement, as
well as for any and all other indebtedness, obligations and liabilities of the
Debtors, or any of them individually, to the Secured Creditors with respect to
any Hedging Liability, or any of them individually, evidenced by or otherwise
arising out of or relating to this Agreement or any other Loan Document or (in
the case of any Hedging Liability) any other agreement with any one or more of
the Secured Creditors, in each case, whether now existing or hereafter arising
(and whether arising before or after the filing of a petition in bankruptcy),
due or to become due, direct or indirect, absolute or contingent, and howsoever
evidenced, held or acquired, and (ii) any and all expenses and charges, legal or
otherwise, suffered or incurred by the Secured Creditors, or any of them
individually, in collecting or enforcing any of such indebtedness, obligations
or liabilities or in realizing on or protecting or preserving any security
therefor, including, without limitation, the lien and security interest granted
hereby (all of the foregoing being hereinafter referred to as the
"Obligations"). Notwithstanding anything in this Agreement to the contrary, the
right of recovery against any Debtor (other than the Company to which this
limitation shall not apply) under this Agreement shall not exceed $1 less than
the amount which would render such Debtor's obligations under this Agreement
void or voidable under applicable law, including fraudulent conveyance law.

               Section 3. Covenants,  Agreements,  Representations  and  
Warranties.  Each Debtor hereby  covenants  and agrees with, and represents and 
warrants to the Secured Creditors that:

                   (a) Such Debtor is duly organized and existing under the laws
         of the state of its organization, is the sole and lawful owner of its
         Collateral and has full right, power and authority to enter into this
         Agreement and to perform each and all of the matters and things herein
         provided for; and the execution and delivery of this Agreement, and the


                                     -5-
<PAGE>   6

         observance and performance of any of the matters and things herein set
         forth, will not violate or contravene any provision of law or of the
         articles of incorporation, by-laws or operating agreement of such
         Debtor, as applicable, or of any indenture, loan agreement or other
         agreement of or affecting such Debtor or any of its properties, or
         result in the creation or imposition of any liens or encumbrance on any
         property of such Debtor.

                   (b) The Collateral is in each Debtor's possession at the
         locations listed under Column 1 on Schedule A attached hereto. Each
         Debtor's respective chief executive office and chief place of business
         is listed opposite its name on Schedule A attached hereto and the
         Debtors have no other places of business other than those listed under
         Column 4 on Schedule A attached hereto. No Debtor will remove its
         Collateral from the locations specified in the first sentence of this
         Section 3(b) without prior written notice to the Agent, unless such
         Collateral will be moved to a location outside the United States, in
         which event, the Agent's prior written consent shall be required, which
         consent shall not be unreasonably withheld (provided that if for any
         reason Collateral is at any time kept or located at locations other
         than its present location or locations hereafter consented to by the
         Agent shall nevertheless have and retain a security interest therein).

                   (c) The Collateral and every part thereof is and will be free
         and clear of all security interests, liens (including, without
         limitation, mechanic's, laborer's and statutory liens), attachments,
         levies and encumbrances of every kind, nature and description and
         whether voluntary or involuntary except for the security interest of
         the Agent therein and as otherwise provided in the Credit Agreement,
         and each Debtor will warrant and defend its Collateral against any
         claims and demands of all persons at any time claiming the same or any
         interest therein adverse to any Secured Creditor.

                   (d) Each Debtor will pay promptly when due all taxes,
         assessments, and governmental charges and levies upon or against its
         Collateral in each case before the same become delinquent and before
         penalties accrue thereon, unless and to the extent that the same are
         being contested in good faith by appropriate proceedings.

                   (e) Each Debtor at its own cost and expense will maintain,
         keep and preserve its Collateral in good repair and condition and will
         not waste or destroy such Collateral or any part thereof and will not
         be negligent in the care and use of any Collateral and will not use or
         permit to be used any Collateral in violation of any statute, ordinance
         or other governmental requirement. Each Debtor will perform its
         obligations under any contract or other agreement constituting part of
         the Collateral, it being understood and agreed that the Secured
         Creditors have no responsibility to perform such obligations.

                   (f) Except for liens expressly permitted by the Credit
         Agreement, and subject to Sections 5(a), 7(b) and 7(c) hereof, no
         Debtor will, without the Agent's prior written consent, sell, assign,
         mortgage, lease or otherwise dispose of its Collateral or any interest
         therein.

                   (g) Each Debtor will insure its Collateral which is insurable
         against such risks and hazards as other companies similarly situated
         insure against, and including in any event loss or damage by fire,
         theft, burglary, pilferage, loss in transit and such other hazards as
         the Agent may specify, in amounts and under policies containing loss
         payable clauses to the Agent as its interest may appear (and, if the
         Agent requests, naming the Secured Creditors as additional insureds
         therein) by insurers acceptable to the Agent. In case of any material
         loss, damage to or destruction of its Collateral or any part thereof,
         the appropriate Debtor shall promptly give written notice thereof to
         the Agent generally describing the nature and extent of such damage or
         destruction. In the event any Debtor shall receive any proceeds of such
         insurance, such Debtor will immediately pay over such proceeds to the
         Agent. Net insurance proceeds received by the Agent under the
         provisions hereof or under any policy or policies of insurance covering
         the Collateral or any part thereof shall be applied to the reduction of
         the Obligations (whether or not then due); provided, however, that the
         Agent may in its sole discretion release any or all such insurance
         proceeds to the appropriate Debtor. All insurance proceeds shall be
         subject to the lien and security interest of the Agent hereunder.

                  UNLESS THE DEBTORS PROVIDE THE AGENT WITH EVIDENCE OF THE
         INSURANCE COVERAGE REQUIRED BY THIS AGREEMENT, THE AGENT MAY PURCHASE
         INSURANCE AT THE DEBTORS' EXPENSE TO PROTECT THE AGENT'S INTERESTS IN
         THE COLLATERAL. THIS INSURANCE MAY, BUT NEED NOT, PROTECT ANY DEBTOR'S
         INTERESTS IN THE COLLATERAL. THE COVERAGE PURCHASED BY THE AGENT MAY
         NOT PAY ANY CLAIMS THAT ANY DEBTOR MAKES OR ANY CLAIM THAT IS MADE
         AGAINST SUCH DEBTOR IN CONNECTION WITH THE COLLATERAL. THE DEBTORS MAY
         LATER CANCEL ANY SUCH INSURANCE PURCHASED BY THE AGENT, BUT ONLY AFTER
         PROVIDING THE AGENT WITH EVIDENCE THAT THE DEBTORS HAVE OBTAINED
         INSURANCE AS REQUIRED BY THIS AGREEMENT. IF THE AGENT PURCHASES
         INSURANCE FOR THE COLLATERAL, THE DEBTORS WILL BE RESPONSIBLE FOR THE
         COSTS OF THAT INSURANCE, INCLUDING INTEREST AND ANY OTHER CHARGES THAT
         THE AGENT MAY IMPOSE IN CONNECTION WITH THE PLACEMENT OF THE INSURANCE,
         UNTIL THE EFFECTIVE DATE OF THE CANCELLATION OR EXPIRATION OF THE
         INSURANCE. THE COSTS OF THE INSURANCE MAY BE ADDED TO THE OBLIGATIONS
         SECURED HEREBY. THE COSTS OF THE INSURANCE MAY BE MORE THAN THE COST OF
         INSURANCE THE DEBTORS MAY BE ABLE TO OBTAIN ON THEIR OWN.

                   (h) Each Debtor will at all times allow the Agent, any
         Secured Creditor or their respective representatives free access to and
         right of inspection of the Collateral. Each Debtor will, to the extent
         it is within its power so to do, authorize and instruct all bailees and
         other parties at any time holding, storing, shipping or transferring
         all or any part of such Debtor's Collateral to permit the Agent, any
         Secured Creditor or their respective or its designees to examine and
         inspect any of such Collateral then in such party's possession and to
         verify from such party's own books and records any information
         concerning such Collateral or any part thereof which the Agent or such
         Secured Creditor may seek to verify. As to any premises not owned by
         any of the Debtors wherein any of the Collateral is located, if any,
         the appropriate Debtor shall, unless the Agent requests otherwise,
         cause each Person having any right, title or interest in, or lien on,
         any of such premises to enter into an agreement (any such agreement to
         contain a legal description of such premises) whereby such party
         disclaims any right, title and interest in, and lien on, the
         Collateral, allowing the removal of such Collateral by the Agent or its
         designee and otherwise in form and substance acceptable to the Agent.

                   (i) Each Debtor agrees from time to time to deliver to the
         Agent and any Secured Creditor such evidence of the existence and
         identity of such Debtor's Collateral and of its availability as
         collateral security pursuant hereto (including, without limitation,
         schedules describing all Receivables created or acquired by such
         Debtor, copies of customer invoices or the equivalent and original
         shipping or delivery receipts for all merchandise and other goods sold
         or leased or services rendered, together with such Debtor's warranty of
         the genuineness thereof, and reports stating the book value of
         Inventory and Equipment by major category and location), as the Agent
         or such Secured Creditor may request. Each Debtor will promptly notify
         the Agent and each Secured Creditor of any Collateral which such Debtor
         has determined to have been rendered obsolete, stating the prior book
         value of such Collateral, its type and location.

                   (j) Each Debtor will comply with the terms and conditions of
         any leases, easements, right-of-way agreements or other agreements
         covering the premises wherein its Collateral is located and any orders,
         ordinances, laws or statutes of any city, state or other governmental
         entity, department or agency having jurisdiction with respect to such
         premises or the conduct of business thereon.

                   (k) On failure of any Debtor to perform any of the covenants
         and agreements herein contained, the Agent may, at its option, perform
         the same and in so doing may expend such sums as the Agent may deem
         advisable in the performance thereof, including without limitation the
         payment of any insurance premiums, the payment of any taxes, liens and
         encumbrances, expenditures made in defending against any adverse claim
         and all other expenditures which the Agent may be compelled to make by
         operation of 



                                     -8-
<PAGE>   9

         law or which the Agent may make by agreement or otherwise
         for the protection of the security hereof. All such sums and amounts so
         expended shall be repayable by the Debtors immediately without notice
         or demand, shall constitute so much additional Obligations hereby
         secured and shall bear interest from the date said amounts are expended
         at the rate per annum (computed on the basis of a 365-day or 366 day
         year, as the case may be, for the actual number of days elapsed)
         determined by adding 2% to the Base Rate (such rate per annum as so
         determined being hereinafter referred to as the "Default Rate"). No
         such performance of any covenant or agreement by the Agent on behalf of
         any Debtor and no such advancement or expenditure therefor, shall
         relieve any Debtor of any default under the terms of this Agreement or
         in any way obligate the Agent or any Secured Creditor to take any
         further or future action with respect thereto. The Agent, in making any
         payment hereby authorized, may do so according to any bill, statement
         or estimate procured from the appropriate public office or holder of
         the claim to be discharged without inquiry into the accuracy of such
         bill, statement or estimate or into the validity of any tax assessment,
         sale, forfeiture, tax lien or title or claim. The Agent, in performing
         any act hereunder, shall be the sole judge of whether the relevant
         Debtor is required to perform same under the terms of this Agreement.
         The Agent is authorized to charge any depository account of any Debtor
         maintained with the Agent for the amount of such sums and amounts so
         expended.

                   (l) Each Debtor warrants that such Debtor has not transacted
         business, and does not transact business, under any trade names except
         as set forth on Schedule B. Each Debtor agrees that it will not change
         its name or transact business under any trade names without first
         giving the Agent 30 days' prior written notice of its intent to do so.

                   (m) Each Debtor agrees to execute and deliver to the Agent
         such further agreements and assignments or other instruments and to do
         all such other things as the Agent may deem necessary or appropriate to
         assure the Agent its security interest hereunder, including such
         financing statement or statements or amendments thereof or supplements
         thereto or other instruments as the Agent or the Required Lenders may
         from time to time require in order to comply with the Uniform
         Commercial Code as enacted in the State of Illinois and any successor
         statute(s) thereto (the "Code"). Each Debtor hereby agrees that a
         carbon, photographic or other reproduction of this Agreement or any
         such financing statement is sufficient for filing as a financing
         statement by the Agent without notice thereof to any Debtor wherever
         the Agent in its sole discretion desires to file the same. In the event
         for any reason the law of any other jurisdiction than Illinois becomes
         or is applicable to the Collateral or any part thereof, or to any of
         the Obligations, each Debtor agrees to execute and deliver all such
         instruments and to do all such other things as the Agent in its sole
         discretion deems necessary or appropriate to preserve, protect and
         enforce the security interests of the Agent under the law of such other


                                     -9-
<PAGE>   10

         jurisdiction to at least the same extent as such security interests
         would be protected under the Code. If any Collateral is in the
         possession or control of any Debtor's agents or processors and unless
         the Agent requests otherwise, such Debtor agrees to notify such agents
         or processors in writing of the Agent's security interests therein, and
         upon the Agent's request instruct them to hold all such Collateral for
         the Agent's account and subject to the Agent's instructions. The
         Debtors agree to mark their books and records to reflect the security
         interests of the Agent in the Collateral.

               Section 4. Special Provisions Re: Receivables. (a) As of the time
any Receivable becomes subject to the security interest provided for hereby and
at all times thereafter, each Debtor shall be deemed to have warranted as to
each and all of such Receivables that all warranties of such Debtor set forth in
this Agreement are true and correct with respect to such Receivables; that each
Receivable and all papers and documents relating thereto are genuine and in all
respects what they purport to be; that each Receivable is valid and subsisting
and, if such Receivable is an account, arises out of a bona fide sale of goods
sold and delivered by such Debtor to, or in the process of being delivered to,
or out of and for services theretofore actually rendered by such Debtor to, the
account debtor named therein; that no such Receivable is evidenced by any
instrument or chattel paper unless such instrument or chattel paper has
theretofore been endorsed by such Debtor and delivered to the Agent (except to
the extent the Agent specifically requests such Debtor not to do so with respect
to any such instrument or chattel paper); that no surety bond was required or
given in connection with said Receivable or the contracts or purchase orders out
of which the same arose; that the amount of the Receivable represented as owing
is the correct amount actually and unconditionally owing, except for normal cash
discounts on normal trade terms in the ordinary course of business if such
Receivable is an account and that the amount of such Receivable represented as
owing is not disputed and is not subject to any set-offs, credits, deductions or
countercharges other than those arising in the ordinary course of such Debtor's
business which are disclosed to the Agent in writing promptly upon such Debtor
becoming aware thereof; provided, however, that the untruth of the foregoing
warranties of this sentence as to Receivables aggregating not more than $100,000
shall not constitute a breach of this sentence. Without limiting the foregoing,
if any Receivable arises out of a contract with the United States of America or
any of its departments, agencies or instrumentalities, if and to the extent the
Agent so requests, each Debtor agrees to notify the Agent and execute whatever
instruments and documents are required by the Agent in order that such
Receivable shall be assigned to the Agent and that proper notice of such
assignment shall be given under the federal Assignment of Claims Act (or any
successor statute).

           (b) Each Debtor shall keep all of its books and records relating to
the Receivables only at its chief executive office described in Section 3(b)
hereof.

                                    -10-

           (c) Unless and until an Event of Default occurs, any merchandise
which is returned by a customer or account debtor or otherwise recovered may be
resold by the Debtors in the ordinary course of their respective businesses in
accordance with Section 5(b) hereof; after an Event of Default occurs, such
merchandise shall be set aside and held by each of the Debtors as trustee for
the Secured Creditors and shall remain part of the Agent's Collateral. Unless
and until an Event of Default occurs, each Debtor may settle and adjust disputes
and claims with its customers and account debtors, handle returns and recoveries
and grant discounts, credits and allowances in the ordinary course of its
business and otherwise for amounts and on terms which such Debtor considers
advisable. However, after an Event of Default has occurred and unless the Agent
requests otherwise, each Debtor shall notify the Agent promptly of all returns
and recoveries and on request deliver the merchandise to the Agent. After an
Event of Default has occurred and unless the Agent requests otherwise, each
Debtor shall also notify the Agent promptly of all disputes and claims and
settle or adjust them at no expense to the Agent or the Secured Creditors, but
no discount, credit or allowance other than on normal trade terms in the
ordinary course of business shall be granted to any customer or account debtor
and no returns of merchandise shall be accepted by such Debtor without the
Agent's consent. The Agent may, at all times after such an Event of Default has
occurred, settle or adjust disputes and claims directly with customers or
account debtors for amounts and upon terms which the Agent considers advisable.

           (d) From time to time, as the Agent may request of any Debtor, such
Debtor shall provide the Agent with schedules describing all Receivables created
or acquired by such Debtor, provided, however, that the failure of such Debtor
to execute and deliver such schedules shall not affect or limit the Agent's
security interest or other rights in and to any such Receivables. Together with
each schedule, each Debtor shall if requested by the Agent, furnish copies of
customers' invoices or the equivalent, and original shipping or delivery
receipts, for all merchandise sold, and each Debtor warrants the genuineness
thereof.

               Section 5. Collection of Receivables. (a) Except as otherwise
provided in this Agreement each Debtor shall make collection of all of its
Receivables and may use the same to carry on its business in accordance with
sound business practice and otherwise subject to the terms hereof.

           (b) Whether or not the Agent has exercised any or all of its rights
under other provisions of this Section 5 and whether or not any Event of Default
has occurred, at the request of the Agent, each Debtor agrees that: (i) all
instruments and chattel paper at any time constituting part of the Collateral
(including any post-dated checks) shall, upon receipt by the relevant Debtor, be
immediately endorsed to and deposited with Agent; and (ii) such Debtor shall
instruct all account debtors to remit all payments in respect of its Receivables
to a lockbox or lockboxes from which deposits will be made into one or more
accounts maintained with the 



                                    -11-
<PAGE>   12


Agent or under  the  control  by  agreement  of the Agent  (whether  or not
maintained with the Agent), the Debtors acknowledging that each such account and
all funds contained therein constitute Collateral hereunder.

           (c) Whether or not any Event of Default has occurred and whether or
not the Agent has exercised any or all of its rights under other provisions of
this Section 5, in the event the Agent requests any Debtor to do so, all
instruments and chattel paper at any time constituting part of the Receivables
(including any postdated checks) shall, upon receipt by such Debtor, be
immediately endorsed to and deposited with the Agent.

           (d) Upon the occurrence and during the continuation of any Event of
Default and whether or not the Agent has exercised any or all of its rights
under other provisions of this Section 5, the Agent or its designee may notify
any Debtor's customers or account debtors at any time that Receivables have been
assigned to the Agent or of the Agent's security interest therein and either in
its own name, or such Debtor's or both, demand, collect (including without
limitation through a lockbox analogous to that described in Section 5(b)
hereof), receive, receipt for, sue for, compound and give acquittance for any or
all amounts due or to become due on Receivables, and in the Agent's discretion
file any claim or take any other action or proceeding which the Agent may deem
necessary or appropriate to protect and realize upon the security interest of
the Agent in the Receivables.

           (e) Any proceeds of Receivables or other Collateral transmitted to or
otherwise received by the Agent pursuant to any of the provisions of Sections
5(b), 5(c) or 5(d) hereof shall be handled and administered by the Agent in and
through a remittance account maintained at the Agent and each Debtor
acknowledges that the maintenance of such remittance account by the Agent is
solely for the Agent's own convenience and that such Debtor does not have any
right, title or interest in such remittance account or any amounts at any time
standing to the credit thereof. The Agent may apply all or any part of any
proceeds of Receivables or other Collateral received by it from any source to
the payment of the Obligations (whether or not then due and payable), such
applications to be made in such amounts, in such manner and order and at such
intervals as the Agent may from time to time in its discretion determine, but
not less often than once each week. The Agent need not apply or give credit for
any item included in proceeds of Receivables or other Collateral until the Agent
has received final payment therefor at its office in cash or final solvent
credits current in Chicago, Illinois, acceptable to the Agent as such. However,
if the Agent does give credit for any item prior to receiving final payment
therefor and the Agent fails to receive such final payment or an item is charged
back to the Agent for any reason, the Agent may at its election in either
instance charge the amount of such item back against the remittance account,
together with interest thereon at the Default Rate. Each Debtor shall accompany
each transmission of any proceeds of Receivables or other Collateral to the
Agent with a report in such form as the Agent shall require identifying the
particular Receivable 

                                    -12-
<PAGE>   13

or other  Collateral  from which the same  arises or  relates.  The Debtors
hereby  jointly and severally  indemnify the Secured  Creditors from and against
all liabilities,  damages, losses, actions, claims, judgments,  costs, expenses,
charges  and  attorney's  fees  suffered or incurred by the Agent or the Secured
Creditors because of the maintenance of the foregoing arrangements.  The Secured
Creditors shall have no liability or  responsibility to any Debtor for accepting
any check, draft or other order for payment of money bearing the legend "payment
in  full"  or words  of  similar  import  or any  other  restrictive  legend  or
endorsement  whatsoever or be responsible for determining the correctness of any
remittance.

               Section 6. Special Provisions Re: Investment Property. (a) Unless
and until an Event of Default has occurred and is continuing and thereafter 
until notified to the contrary by the Agent pursuant to Section 9(e) hereof:

                   (i) Each Debtor shall be entitled to exercise all voting
         and/or consensual powers pertaining to the Investment Property or any
         part thereof owned or held by it, for all purposes not inconsistent
         with the terms of this Agreement, the Credit Agreement or any other
         document evidencing or otherwise relating to any Obligations; and

                  (ii) Each Debtor shall be entitled to receive and retain all
         cash dividends paid upon or in respect of the Investment Property owned
         or held by it.

           (b) Certificates for all securities now or at any time constituting
Investment Property hereunder shall be promptly delivered by the relevant Debtor
to the Agent duly endorsed in blank for transfer or accompanied by an
appropriate assignment or assignments or an appropriate undated stock power or
powers, in every case sufficient to transfer title thereto, and, with respect to
any Investment Property held by a securities intermediary, commodity
intermediary, or other financial intermediary of any kind, the relevant Debtor
shall execute and deliver, and shall cause any such intermediary to execute and
deliver, an agreement among such Debtor, the Agent, and such intermediary in
form and substance satisfactory to the Agent which provides, among other things,
for the intermediary's agreement that it will comply with entitlement orders,
and apply any value distributed on account of any Investment Property maintained
in an account with such intermediary, as directed by the Agent without further
consent by such Debtor at any time after the occurrence of any Event of Default;
provided, however, that, prior to the existence of an Event of Default and
thereafter until otherwise required by the Agent or the Required Lenders, a
Debtor shall not be required to deliver any such certificates or cause any such
agreement to be entered into with the relevant financial intermediary if and so
long as (i) the fair market value of any such Investment Property held by such
Debtor is less than $100,000 and (ii) the aggregate fair market value of all
such Investment Property held by the Debtors and not subject to the control (as
such term is defined in the Code) of the Agent under the Collateral Documents is
less than $250,000 at any one time outstanding. The Agent may at any time after
the occurrence of 


                                    -13-
<PAGE>   14

an Event of Default cause to be transferred into its name or the name of its 
nominee or nominees any and all of the Investment Property hereunder.

           (c) Unless and until an Event of Default has occurred and is
continuing, each Debtor may sell or otherwise dispose of any Investment Property
to the extent permitted by the Credit Agreement, provided that no Debtor shall
sell or otherwise dispose of any capital stock or other equity interests in any
other Debtor or any direct or indirect Subsidiary of any Debtor without the
Agent's prior written consent. During the existence of any Event of Default, no
Debtor shall sell or otherwise dispose of all or any part of the Investment
Property without the prior written consent of the Agent.

           (d) Each Debtor represents that on the date of this Agreement, none
of the Investment Property consists of margin stock (as such term is defined in
Regulation U of the Board of Governors of the Federal Reserve System) except to
the extent such Debtor has delivered to the Agent a duly executed and completed
Form U-1 with respect to such stock. If at any time the Investment Property or
any part thereof consists of margin stock, the relevant Debtor shall promptly so
notify the Agent and deliver to the Agent a duly executed and completed Form U-1
and such other instruments and documents reasonably requested by the Agent in
form and substance satisfactory to the Agent.

           (e) Notwithstanding anything to the contrary contained herein, in the
event any Investment Property is subject to the terms of a separate security
agreement (including, without limitation, the Pledge Agreement bearing even date
herewith relating to the equity interests issued by certain of the Debtors
hereunder) in favor of the Agent, the terms of such separate security agreement
shall govern and control unless otherwise agreed to in writing by the Secured
Creditors.

               Section 7. Special Provisions Re: Inventory and Equipment. (a)
Each Debtor will at its own cost and expense maintain, keep and preserve its
Inventory in good and merchantable condition and keep and preserve its Equipment
in good repair, working order and condition, ordinary wear and tear excepted,
and without limiting the foregoing make all necessary and proper repairs,
replacements and additions to the Equipment so that the efficiency thereof shall
be fully preserved and maintained.

           (b) Each Debtor may, until an Event of Default has occurred and is
continuing and thereafter until otherwise notified by the Agent, use, consume
and sell its Inventory in the ordinary course of its business as presently
conducted, but a sale in the ordinary course of business shall not under any
circumstance include any transfer or sale in satisfaction, partial or complete,
of a debt owing by any Debtor.

                                    -14-
<PAGE>   15

           (c) Each Debtor may, until an Event of Default has occurred and is
continuing and thereafter until otherwise notified by the Agent, sell (i)
obsolete, worn out or unusable Equipment which is concurrently replaced with
similar Equipment at least equal in quality and condition to that sold and owned
by such Debtor free of any lien, charge or encumbrance other than the lien
hereof and (y) Equipment which is not necessary for, or of importance to, the
proper conduct of any Debtor's business in the ordinary course and failure to
repair or replace such Equipment would not be disadvantageous to the rights
hereunder of the Secured Creditors.

           (d) As of the time any Inventory or Equipment becomes subject to the
security interest provided for hereby and at all times thereafter, each Debtor
shall be deemed to have warranted as to any and all of its Inventory and
Equipment that all warranties of such Debtor set forth in this Agreement are
true and correct with respect to such Inventory and Equipment and that all of
such Inventory and Equipment is located at a location set forth pursuant to
Section 3(b) hereof. Each Debtor warrants and agrees that no Inventory is or
will be consigned to any other person without the Agent's prior written consent.

           (e) Each Debtor shall at its own cost and expense cause the lien of
the Agent in and to any portion of its Collateral subject to a certificate of
title law to be duly noted on such certificate of title or to be otherwise filed
in such manner as is prescribed by law in order to perfect such lien and shall
cause all such certificates of title and evidences of lien to be deposited with
the Agent unless otherwise permitted by the Required Lenders in their sole
discretion; provided that no Debtor shall be obligated to cause the Agent's lien
to be so noted or to deliver any such certificate of title to the Agent to the
extent such certificate is held by another creditor with a purchase money
security interest permitted by the Credit Agreement on the Collateral
represented by such certificate.

           (f) Each Debtor shall at its own cost and expense cause any
certificate of title evidencing any of the Collateral to be amended to reflect
the current and correct name of such Debtor as and when required by applicable
law, but in any event no later than such date on which such Debtor must renew
its registration of such Collateral under applicable law. Each Debtor shall
cause the lien of the Agent in such Collateral to continue to be duly noted on
such amended or reissued certificate of title.

           (g) Except for Equipment from time to time located on the real estate
described on Schedule C attached hereto and as otherwise disclosed to the Agent
in writing, none of the Equipment is or will be attached to real estate in such
a manner that the same may become a fixture.

           (h) If any of its Inventory is at any time evidenced by a document of
title, such document shall be promptly delivered by the appropriate Debtor to
the Agent.

                                    -15-
<PAGE>   16

               Section 8. Power of Attorney. In addition to any other powers of
attorney contained herein, each Debtor appoints the Agent, its nominee, or any
other person whom the Agent may designate as such Debtor's attorney in fact,
with full power to endorse such Debtor's names on any checks, notes,
acceptances, money orders, drafts or other forms of payment or security that may
come into the Agent's possession, to sign such Debtor's names on any invoice or
bill of lading relating to any Receivables, on drafts against customers, on
schedules and assignments of Receivables, on notices of assignment, on public
records, on verifications of accounts and on notices to customers, to send
requests for verification of Receivables to customers or account debtors, to
notify the post office authorities to change the address for delivery of such
Debtor's mail to an address designated by the Agent and to receive, open and
dispose of all mail addressed to such Debtor and to do all other things
necessary to carry out this Agreement. Each Debtor hereby ratifies and approves
all acts of any such attorney and agree that neither the Agent nor any such
attorney nor any Secured Creditor will be liable for any acts or omissions nor
for any error of judgment or mistake of fact or law other than their own gross
negligence or willful misconduct. The foregoing power of attorney, being coupled
with an interest, is irrevocable until the Obligations have been fully satisfied
and any commitment of the Secured Creditors to extend credit constituting
Obligations has terminated. The Agent may file one or more financing statements
disclosing its security interest in any or all of the Collateral without any
Debtor's signature appearing thereon. Each Debtor also hereby grants the Agent a
power of attorney to execute any such financing statement, or amendments and
supplements to financing statements, on behalf of such Debtor without notice
thereof to any Debtor, which power of attorney is coupled with an interest and
is irrevocable until the Obligations have been fully satisfied and any
commitment of the Secured Creditors to extend credit constituting Obligations to
the Company has terminated.

               Section 9. Defaults and Remedies. (a) The occurrence of any event
or the existence of any condition which is specified as an Event of Default
under the Credit Agreement shall constitute an "Event of Default" hereunder.

           (b) Upon the occurrence of any Event of Default, the Agent shall
have, in addition to all other rights provided herein or by law, the rights and
remedies of a secured party under the Code (regardless of whether the Code is
the law of the jurisdiction where the rights or remedies are asserted and
regardless of whether the Code applies to the affected Collateral), and further
the Agent may, without demand and without advertisement, notice, hearing or
process of law, all of which each Debtor hereby waives to the extent permitted
by law, at any time or times, sell and deliver any or all Collateral held by or
for it at public or private sale, for cash, upon credit or otherwise, at such
prices and upon such terms as the Agent deems advisable, in its sole discretion.
In addition to all other sums due the Agent and the Secured Creditors hereunder,
the Debtors jointly and severally agree to pay to the Agent and the Secured
Creditors all costs and expenses incurred by the Agent and the Secured
Creditors, including reasonable attorneys' fees 

                                    -16-
<PAGE>   17

and court costs, in obtaining, liquidating or enforcing payment of Collateral or
Obligations or in the prosecution or defense of any action or proceeding by or
against the Agent or such other Secured Creditor or the Debtors or any of them
concerning any matter arising out of or connected with this Agreement or the
Collateral or Obligations, including without limitation any of the foregoing
arising in, arising under or related to a case under the Bankruptcy Code. Any
requirement of reasonable notice shall be met if such notice is personally
served on or mailed, postage prepaid, to the Debtors in accordance with Section
14(b) hereof at least ten days before the time of sale or other event giving
rise to the requirement of such notice; however, no notification need be given
to a Debtor if that Debtor has signed, after an Event of Default has occurred, a
statement renouncing any right to notification of sale or other intended
disposition. The Agent shall not be obligated to make any sale or other
disposition of the Collateral regardless of notice having been given. The Agent
or any Secured Creditor may be the purchaser at any such sale. To the extent
permitted by applicable law, each Debtor hereby waives all of its rights of
redemption from any such sale. Subject to the provisions of applicable law, the
Agent may postpone or cause the postponement of the sale of all or any portion
of the Collateral by announcement at the time and place of such sale, and such
sale may, without further notice, be made at the time and place to which the
sale was postponed or the Agent may further postpone such sale by announcement
made at such time and place.

           (c) Without in any way limiting the foregoing, during the existence
of any Event of Default, the Agent shall have the right, in addition to all
other rights provided herein or by law, to take physical possession of any and
all of the Collateral and anything found therein, the right for that purpose to
enter without legal process any premises where the Collateral may be found
(provided such entry be done lawfully), and the right to maintain such
possession on each Debtor's premises (each Debtor hereby agreeing to lease
warehouses without cost or expense to the Agent or its designee if the Agent so
requests) or to remove its Collateral or any part thereof to such other places
as the Agent may desire. During the existence of any Event of Default, the Agent
shall have the right to exercise any and all rights with respect to deposit
accounts of any Debtor maintained with the Agent or any Secured Creditor,
including, without limitation, the right to collect, withdraw and receive all
amounts due or to become due or payable under each such deposit account. During
the existence of any Event of Default, each Debtor shall, upon the Agent's
demand, assemble its Collateral and make it available to the Agent at a place
designated by the Agent. If the Agent exercises its right to take possession of
the Collateral, each Debtor shall also at its expense perform any and all other
steps requested by the Agent to preserve and protect the security interest
hereby granted in the Collateral, such as placing and maintaining signs
indicating the security interest of the Agent, appointing overseers for the
Collateral and maintaining stock records.

           (d) Without in any way limiting the foregoing, each Debtor hereby
grants to the Agent and the Secured Creditors a royalty-free irrevocable license
and right to use all of such 


                                    -17-
<PAGE>   18

Debtor's patents, patent applications, patent licenses, trademarks, trademark
registrations, trademark licenses, trade names, trade styles, and similar
intangibles in connection with any foreclosure or other realization by the Agent
or the Secured Creditors on all or any part of the Collateral, provided that the
license granted hereunder shall not include any rights in any license agreement
under which the relevant Debtor is licensee which, by its terms, prohibits the
license contemplated by this Section. The license and right granted the Secured
Creditors hereby shall be without any royalty or fee or charge whatsoever. Such
license and right shall only be exercisable upon the occurrence and continuation
of an Event of Default.

           (e) Without in any way limiting the foregoing, during the existence
of any Event of Default, all rights of a Debtor to exercise the voting and/or
consensual powers which it is entitled to exercise pursuant to Section 6(a)(i)
hereof and/or to receive and retain the distributions which it is entitled to
receive and retain pursuant to Section 6(a)(ii) hereof, shall, at the option of
the Agent, cease and thereupon become vested in the Agent, which, in addition to
all other rights provided herein or by law, shall then be entitled solely and
exclusively to exercise all voting and other consensual powers pertaining to the
Investment Property and/or to receive and retain the distributions which such
Debtor would otherwise have been authorized to retain pursuant to Section
6(a)(ii) hereof and shall then be entitled solely and exclusively to exercise
any and all rights of conversion, exchange or subscription or any other rights,
privileges or options pertaining to any Investment Property as if the Agent were
the absolute owner thereof including, without limitation, the rights to
exchange, at its discretion, any and all of the Investment Property upon the
merger, consolidation, reorganization, recapitalization or other readjustment of
the respective issuer thereof or upon the exercise by or on behalf of any such
issuer or the Agent of any right, privilege or option pertaining to any
Investment Property and, in connection therewith, to deposit and deliver any and
all of the Investment Property with any committee, depositary, transfer Agent,
registrar or other designated agency upon such terms and conditions as the Agent
may determine. Without limiting the foregoing, during the existence of any Event
of Default, the Agent may, by written demand, direct any securities
intermediary, commodities intermediary, or other financial intermediary at any
time holding any Investment Property, or any issuer thereof, to deliver such
Collateral, or any part thereof, and/or liquidate such Collateral, or any party
thereof, and deliver the proceeds therefrom to the Agent. In the event the Agent
in good faith believes any of the Collateral constitutes restricted securities
within the meaning of any applicable securities laws, any disposition thereof in
compliance with such laws shall not render the disposition commercially
unreasonable.

           (f) The powers conferred upon the Agent hereunder are solely to
protect its interest in the Collateral and shall not impose on it any duty to
exercise such powers. The Agent shall be deemed to have exercised reasonable
care in the custody and preservation of Investment Property in its possession if
such Collateral is accorded treatment substantially equivalent to that which the
Agent accords its own property consisting of similar type assets, it being
understood, 


                                    -18-
<PAGE>   19

however, that the Agent shall have no responsibility for ascertaining or taking
any action with respect to calls, conversions, exchanges, maturities, tenders,
or other matters relating to any such Collateral, whether or not the Agent has
or is deemed to have knowledge of such matters. This Agreement constitutes an
assignment of rights only and not an assignment of any duties or obligations of
any Debtor in any way related to the Collateral, and the Agent shall have no
duty or obligation to discharge any such duty or obligation. The Agent shall
have no responsibility for taking any necessary steps to preserve rights against
any parties with respect to any Collateral or initiating any action to protect
the Collateral against the possibility of a decline in market value. Neither the
Agent or any Secured Creditor, nor any party acting as attorney for the Agent or
any Secured Creditor, shall be liable for any acts or omissions or for any error
of judgment or mistake of fact or law other than such person's gross negligence
or willful misconduct.

           (g) Failure by the Agent or any Secured Creditor to exercise any
right, remedy or option under this Agreement or any other agreement between the
Debtors or any of them and the Agent or any Secured Creditor or Secured
Creditors or provided by law, or delay by the Agent or any Secured Creditor in
exercising the same, shall not operate as a waiver; no waiver shall be effective
unless it is in writing, signed by the party against whom enforcement of the
waiver is sought and then only to the extent specifically stated. Neither the
Agent, any Secured Creditor nor any party acting as attorney for the Agent or
such Secured Creditor, shall be liable for any acts or omissions or for any
error of judgment or mistake of fact or law other than their gross negligence or
willful misconduct. The rights and remedies of the Secured Creditors under this
Agreement shall be cumulative and not exclusive of any other right or remedy
which the Agent or any Secured Creditor may have. For purposes of this
Agreement, an Event of Default shall be construed as continuing after its
occurrence until the same is waived in writing by the Lenders or the Required
Lenders, as the case may be, in accordance with the Credit Agreement.

              Section 10. Application of Proceeds. The proceeds and avails of
the Collateral at any time received by the Agent upon the occurrence and during
the continuation of any Event of Default shall, when received by the Agent in
cash or its equivalent, be applied by the Agent in reduction of the Obligations
in accordance with the terms of the Credit Agreement. The Debtors shall remain
liable to the Agent and the Secured Creditors for any deficiency. Any surplus
remaining after the full payment and satisfaction of the Obligations shall be
returned to the Debtors or to whomsoever the Agent reasonably determines is
lawfully entitled thereto.

              Section 11. Continuing Agreement. This Agreement shall be a
continuing agreement in every respect and shall remain in full force and effect
until all of the Obligations, both for principal and interest, have been fully
paid and satisfied and any commitment to extend any credit constituting
Obligations to the Company shall have terminated.

                                    -19-
<PAGE>   20


              Section 12. Primary Security; Obligations Absolute. The lien and
security herein created and provided for stand as direct and primary security
for the Obligations. No application of any sums received by the Agent in respect
of the Collateral or any disposition thereof to the reduction of the Obligations
or any portion thereof shall in any manner entitle any Debtor to any right,
title or interest in or to the Obligations or any collateral security therefor,
whether by subrogation or otherwise, unless and until all Obligations have been
fully paid and satisfied and any commitment to extend credit constituting
Obligations to the Company shall have terminated. Each Debtor acknowledges and
agrees that the lien and security hereby created and provided for are absolute
and unconditional and shall not in any manner be affected or impaired by any
acts or omissions whatsoever of the Agent, any Secured Creditor or any other
holder of any of the Obligations, and without limiting the generality of the
foregoing, the lien and security hereof shall not be impaired by any acceptance
by the Agent, any Secured Creditor or any holder of any of the Obligations of
any other security for or guarantors upon any of the Obligations or by any
failure, neglect or omission on the part of the Agent, any Secured Creditor or
any other holder of any of the Obligations to realize upon or protect any of the
Obligations or any collateral security therefor. The lien and security hereof
shall not in any manner be impaired or affected by (and the Agent and the
Secured Creditors, without notice to anyone, are hereby authorized to make from
time to time) any sale, pledge, surrender, compromise, settlement, release,
renewal, extension, indulgence, alteration, substitution, exchange, change in,
modification or disposition of any of the Obligations, or of any collateral
security therefor, or of any guaranty thereof or of any obligor thereon. The
Secured Creditors may at their discretion at any time grant credit to the
Company without notice to any Debtor in such amounts and on such terms as the
Secured Creditors may elect (all of such to constitute additional Obligations)
without in any manner impairing the lien and security hereby created and
provided for. No release, compromise or discharge of any Debtor hereunder or
with respect to any of the Obligations or any Collateral provided by such Debtor
shall release or discharge, or impair the agreements of, any other Debtor
hereunder or in any manner impair the liens and security interests granted by
any other Debtor hereunder; and the Agent may proceed against the Collateral
provided hereunder by any one or more of the Debtors without proceeding against
any or all of the other Debtors, their respective properties or any other
security or guaranty whatsoever. Without limiting the generality of the
foregoing, the Agent (acting at the direction of the Secured Creditors) may at
any time or from time to time release any Debtor from its obligations hereunder
or release any Collateral or effect any compromise with any Debtor, and no such
release or compromise shall in any manner impair or otherwise effect the liens
granted by, or the obligations of, the other Debtors hereunder. In order to
foreclose or otherwise realize hereon and to exercise the rights granted the
Agent hereunder and under applicable law as against any Debtor or any Collateral
in which such Debtor has rights, there shall be no obligation on the part of the
Agent, any Secured Creditor or any other holder of any of the Obligations at any
time to first resort for payment to the Company or any other Debtor or any other
Person, its property or estate or to any guaranty of the Obligations or any
portion thereof or to resort to any other collateral security, property, liens
or any other rights 


                                    -20-

or remedies whatsoever, and the Agent shall have the right to enforce this
instrument as against any Debtor or any Collateral in which such Debtor has
rights, irrespective of whether or not other proceedings or steps are pending
seeking resort to or realization upon or from any of the foregoing.

              Section 13. The Agent. In acting under or by virtue of this
Agreement, the Agent shall be entitled to all the rights, authority, privileges
and immunities provided in Section 10 of the Credit Agreement, all of which
provisions of said Section 10 are incorporated by reference herein with the same
force and effect as if set forth herein in their entirety. The Agent hereby
disclaims any representation or warranty to the Secured Creditors concerning the
perfection of the security interest granted hereunder or in the value of any of
the Collateral.

              Section 14. Miscellaneous. (a) This Agreement cannot be changed or
terminated orally. All of the rights, privileges, remedies and options given to
the Agent and the Secured Creditors hereunder shall inure to the benefit of
their respective successors and assigns, and all the terms, conditions,
promises, covenants, representations and warranties of and in this Agreement
shall bind each Debtor and its legal representatives, successors and assigns,
provided that no Debtor may assign its rights or delegate its duties hereunder
without the Agent's prior written consent. Without limiting the generality of
the foregoing, and subject to the provisions of Sections 12.14 and 12.15 of the
Credit Agreement, any Lender may assign or otherwise transfer any indebtedness
held by it secured by this Agreement to any other person or entity, and such
other person or entity shall thereupon become vested with all the benefits in
respect thereof granted to such Lender herein or otherwise, subject, however, to
the provisions of the Credit Agreement. Each Debtor hereby releases the Agent
and each Secured Creditor from any liability for any act or omission relating to
its Collateral or this Agreement, except the Agent's or such Secured Creditor's
gross negligence or willful misconduct.

           (b) All communications provided for herein shall be in writing,
except as otherwise specifically provided for hereinabove, and shall be deemed
to have been given or made, if to any Debtor when given to the Company in
accordance with Section 12.8 of the Credit Agreement, or if to the Agent or any
Lender, when given to such party in accordance with Section 12.8 of the Credit
Agreement.

           (c) No Secured Creditor shall have the right to institute any suit,
action or proceeding in equity or at law for the foreclosure against any
Collateral subject to this Agreement or for the execution of any trust or power
hereof or for the appointment of a receiver, or for the enforcement of any other
remedy under or upon this Agreement; it being understood and intended that no
one or more of the Secured Creditors shall have any right in any manner
whatsoever to affect, disturb or prejudice the lien and security interest of
this Agreement by its or their action or to enforce any right hereunder, and
that all proceedings at law or in equity shall be 


                                    -21-
<PAGE>   22

instituted, had and maintained by the Agent in the manner herein provided for
the ratable benefit of the Secured Creditors.

           (d) In the event that any provision hereof shall be deemed to be
invalid by reason of the operation of any law or by reason of the interpretation
placed thereon by any court, this Agreement shall be construed as not containing
such provision, but only as to such locations where such law or interpretation
is operative, and the invalidity of such provision shall not affect the validity
of any remaining provision hereof, and any and all other provisions hereof which
are otherwise lawful and valid shall remain in full force and effect. Without
limiting the generality of the foregoing, in the event that this Agreement shall
be deemed to be invalid or otherwise unenforceable with respect to any Debtor,
such invalidity or unenforceability shall not affect the validity of this
Agreement with respect to the other Debtors.

           (e) Upon the execution and delivery of this Agreement by the Debtors
hereunder, this Agreement shall supersede all provisions of the Prior Security
Agreement as of such date. The Debtors hereby agree that, notwithstanding the
execution and delivery of this Agreement, the lien and security interest created
and provided for under the Prior Security Agreement continue in effect under and
pursuant to the terms of this Agreement for the benefit of all of the
Obligations secured hereby. Nothing herein contained shall in any manner affect
or impair the priority of the liens and security interests created and provided
for by the Prior Security Agreement as to the indebtedness and obligations which
would otherwise be secured hereby prior to giving effect to this Agreement

           (f) This Agreement shall be deemed to have been made in the State of
Illinois and shall be governed by the internal laws of the State of Illinois
(without regard to the principles of conflicts of law). All terms which are used
in this Agreement which are defined in the Code shall have the same meanings
herein as said terms do in the Code unless this Agreement shall otherwise
specifically provide. The headings in this instrument are for convenience of
reference only and shall not limit or otherwise affect the meaning of any
provision hereof.

           (g) This Agreement may be executed in any number of counterparts,
each constituting an original, but all together one and the same instrument.
Each Debtor acknowledges that this Agreement is and shall be effective upon its
execution and delivery by such Debtor to the Agent, and it shall not be
necessary for the Agent to execute this Agreement or any other acceptance hereof
or otherwise to signify or express its acceptance hereof.

           (h) THE AGENT AND THE DEBTORS AGREE THAT ALL DISPUTES AMONG THEM
ARISING OUT OF, CONNECTED WITH, RELATED TO, OR INCIDENTAL TO THE RELATIONSHIP
ESTABLISHED AMONG THEM IN CONNECTION WITH THIS AGREEMENT, AND WHETHER ARISING IN
CONTRACT, TORT, EQUITY, OR OTHERWISE, SHALL BE RESOLVED ONLY BY STATE OR

                      AMENDED AND RESTATED PLEDGE AGREEMENT


         This Amended and Restated Pledge Agreement (the "Agreement") is dated
as of May ___, 1998, by and among the parties executing this Agreement under the
heading "Pledgors" (such parties, along with any parties who execute and deliver
to the Agent an agreement in the form attached hereto as Schedule E, being
hereinafter referred to collectively as the "Pledgors" and individually as a
"Pledgor"), each with its mailing address as set forth on the signature page
hereto and HARRIS TRUST AND SAVINGS BANK, an Illinois banking corporation
("Harris"), with its mailing address at 111 West Monroe Street, Chicago,
Illinois 60603, acting as agent hereunder for the Secured Creditors hereinafter
identified and defined (Harris acting as such agent and any successor or
successors to Harris acting in such capacity being hereinafter referred to as
the "Agent");


                             PRELIMINARY STATEMENTS

            A. Morton Industrial Group, Inc., a Georgia corporation (the
"Company"), certain subsidiaries of the Company, Harris, individually and as
agent, and certain lenders are currently party to a Credit Agreement dated as of
January 20, 1998 (such Credit Agreement, as the same may have been amended or
modified from time to time, including amendments and restatements thereof in its
entirety, being hereinafter referred to as the "Prior Credit Agreement"),
pursuant to which Harris and other lenders from time to time party to the Credit
Agreement agreed, subject to certain terms and conditions, to extend credit and
make certain other financial accommodations available to the "Borrowers"
identified therein.

            B. The Company and certain subsidiaries of the Company are currently
party to a Pledge Agreement dated as of January 20, 1998, with Harris,
individually and as agent for the lenders party to the Prior Credit Agreement
(the "Prior Pledge Agreement"), pursuant to which the Company and such other
subsidiaries have granted liens on certain personal property as collateral
security for the indebtedness, obligations, and liabilities of the "Borrowers"
owing to such lenders under the Prior Credit Agreement.

            C. Concurrently herewith, Harris and the other lenders party to the
Prior Credit Agreement are refinancing all indebtedness, obligations, and
liabilities owed to such lenders by the "Borrowers" under the Prior Credit
Agreement (the "Prior Obligations").

            D. The Company and Harris, individually and as Agent, have also
entered into a Credit Agreement dated of even date herewith (such Credit
Agreement, as the same may be amended or modified from time to time, including
amendments and restatements thereof in its entirety, being hereinafter referred
to as the "Credit Agreement") pursuant to which Harris and 


<PAGE>   2

other lenders which from time to time become party thereto (Harris and such
other lenders which from time to time become party thereto being hereinafter
referred to collectively as the "Lenders" and individually as a "Lender") have
agreed to modify the terms and conditions applicable to the Prior Obligations
and to provide for additional credit and financial accommodations to be made
available to the Company thereunder, all subject to the terms and conditions
therein set forth.

            E. The Company may from time to time enter into one or more interest
rate exchange, cap, collar, floor or other agreements with one or more of the
Lenders party to the Credit Agreement, or their affiliates, for the purpose of
hedging or otherwise protecting the Company against changes in interest rates
(the liability of the Company in respect of such agreements with such Lenders
and their affiliates being hereinafter referred to as the "Hedging Liability")
(the affiliates of the Lenders to which any Hedging Liability is owed, together
with the Lenders and the Agent, being collectively referred to herein as the
"Secured Creditors").

            F. As a condition precedent to extending credit or otherwise making
financial accommodations available to the Company under the Credit Agreement,
the Lenders have required, among other things, that each Pledgor grant to the
Agent for the benefit of the Secured Creditors a lien on and security interest
in certain personal property of such Pledgor pursuant to this Agreement.

            G. The Company owns, directly or indirectly, all or substantially
all of the equity interests in each Pledgor (other than the Company) and
provides each such Pledgor with financial, management, administrative, and
technical support which enables such Pledgor to conduct its business in an
orderly and efficient manner in the ordinary course.

            H. Each Pledgor will benefit, directly or indirectly, from credit
and other financial accommodations extended by the Secured Creditors to the
Company.

         NOW, THEREFORE, for and in consideration of the execution and delivery
by the Lenders of the Credit Agreement, and other good and valuable
consideration, receipt whereof is hereby acknowledged, the parties hereto hereby
agree as follows:

               Section 1. Terms Defined in Credit Agreement. All capitalized
terms used herein without definition shall have the same meanings herein as such
terms have in the Credit Agreement. The term "Pledgor" and "Pledgors" as used
herein shall mean and include the Pledgors collectively and also each
individually, with all grants, representations, warranties and covenants of and
by the Pledgors, or any of them, herein contained to constitute joint and
several grants, representations, warranties and covenants of and by the
Pledgors; provided, however, that unless the context in which the same is used
shall otherwise require, any grant, representation, 




                                      -2-
<PAGE>   3

warranty or covenant contained herein related to the Collateral shall be made by
each Pledgor only with respect to the Collateral owned by it or represented by
such Pledgor as owned by it.

               Section 2. Grant of Security Interest in the Collateral. Each
Pledgor hereby grants to the Agent a security interest in, in each case for the
ratable benefit of the Secured Creditors, and acknowledges and agrees that the
Agent has and shall continue to have for the ratable benefit of the Secured
Creditors a continuing security interest in, any and all right, title and
interest of each Pledgor, whether now owned or existing or hereafter created,
acquired or arising, in and to the following (collectively, the "Collateral"):

                   (a) Stock Collateral. (i) All shares of the capital stock of
         each of the issuers listed and described on Schedule A attached hereto
         owned or held by such Pledgor, whether now owned or hereafter acquired
         (those shares delivered to and deposited with the Agent on the date
         hereof being listed and described on Schedule A attached hereto), and
         all substitutions and additions to such shares (herein, the "Pledged
         Securities"), (ii) all dividends, distributions and sums distributable
         or payable from, upon or in respect of the Pledged Securities and (iii)
         all other rights and privileges incident to the Pledged Securities (all
         of the foregoing being hereinafter referred to collectively as the
         "Stock Collateral");

                   (b) Partnership Interest Collateral. (i) Each partnership
         identified on Schedule B attached hereto and made a part hereof (such
         partnerships being hereinafter referred to collectively as the
         "Partnerships" and individually as a "Partnership") and (ii) any and
         all payments and distributions of whatever kind or character, whether
         in cash or other property, at any time made, owing or payable to such
         Pledgor in respect of or on account of its present or hereafter
         acquired interests in the Partnerships, whether due or to become due
         and whether representing profits, distributions pursuant to complete or
         partial liquidation or dissolution of any such Partnership,
         distributions representing the complete or partial redemption of such
         Pledgor's interest in any such Partnership or the complete or partial
         withdrawal of such Pledgor from any such Partnership, repayment of
         capital contributions, payment of management fees or commissions, or
         otherwise, and the right to receive, receipt for, use and enjoy all
         such payments and distributions (all of the foregoing being hereinafter
         collectively called the "Partnership Interest Collateral"); and

                   (c)     Proceeds.  All proceeds of the foregoing.

All terms which are used in this Agreement which are defined in the Uniform
Commercial Code of the State of Illinois ("UCC") shall have the same meanings
herein as such terms are defined in the UCC, unless this Agreement shall
otherwise specifically provide.


                                      -3-

               Section 3. Obligations Hereby Secured. This Agreement is made and
given to secure, and shall secure, the payment and performance of (i) (x) any
and all indebtedness, obligations and liabilities of the Company to the Agent,
the Lenders, or any of them individually, evidenced by or otherwise arising out
of or relating to the Credit Agreement or any promissory note of the Company
issued at any time under the Credit Agreement (including all notes issued in
extension or renewal thereof or in substitution or replacement therefor) and (y)
any liability of the Pledgors, or any of them individually, arising out of the
Credit Agreement, as well as for any and all other indebtedness, obligations and
liabilities of the Pledgors, or any of them individually, to the Secured
Creditors with respect to any Hedging Liability, or any of them individually,
evidenced by or otherwise arising out of or relating to this Agreement or any
other Loan Document or (in the case of any Hedging Liability) any other
agreement with any one or more of the Secured Creditors, in each case, whether
now existing or hereafter arising (and whether arising before or after the
filing of a petition in bankruptcy), due or to become due, direct or indirect,
absolute or contingent, and howsoever evidenced, held or acquired, and (ii) any
and all expenses and charges, legal or otherwise, suffered or incurred by the
Agent, the Secured Creditors, or any of them individually, in collecting or
enforcing any of such indebtedness, obligations or liabilities or in realizing
on or protecting or preserving any security therefor, including, without
limitation, the lien and security interest granted hereby (all of the foregoing
being hereinafter referred to as the "Obligations"). Notwithstanding anything in
this Agreement to the contrary, the right of recovery against any Pledgor (other
than the Company to which this limitation shall not apply) under this Agreement
shall not exceed $1 less than the amount which would render such Pledgor's
obligations under this Agreement void or voidable under applicable law,
including fraudulent conveyance law.

               Section 4. Covenants, Agreements, Representations and Warranties.
Each Pledgor hereby covenants and agrees with, and represents and warrants to,
the Agent and the Secured Creditors that:

                   (a) Each Pledgor is and shall be the sole and lawful legal,
         record and beneficial owner of its Collateral. Each Pledgor's chief
         executive office or place of business at the address listed under such
         Pledgor's name on Schedule A and Schedule B hereto, as applicable. Each
         Pledgor agrees that it will not change any location set forth on the
         applicable Schedule hereto without prior written notice to the Agent,
         unless such location shall be outside the United States, in which
         event, the Agent's prior written consent shall be required, which
         consent shall not be unreasonably withheld. No Pledgor shall, without
         the Agent's prior written consent, sell, assign, or otherwise dispose
         of the Collateral or any interest therein. The Collateral, and every
         part thereof, is and shall be free and clear of all security interests,
         liens, rights, claims, attachments, levies and encumbrances of every
         kind, nature and description and whether voluntary or involuntary,
         except for the security interest of the Agent hereunder and for other
         Liens 



                                      -4-
<PAGE>   5

         which are expressly permitted by the Credit Agreement. Each Pledgor
         shall warrant and defend the Collateral against any claims and demands
         of all persons at any time claiming the same or any interest in the
         Collateral adverse to the Agent and the Secured Creditors.

                   (b) Each Pledgor agrees to execute and deliver to the Agent
         such further agreements, assignments, instruments and documents and to
         do all such other things as the Agent may deem necessary or appropriate
         to assure the Agent its lien and security interest hereunder, including
         such assignments, acknowledgments (including acknowledgments of
         assignment in the form attached hereto as Schedule C) stock powers,
         financing statements, instruments and documents as the Agent may from
         time to time require in order to comply with the Uniform Commercial
         Code as enacted in the State of Illinois and any successor statute(s)
         thereto (the "UCC"). Each Pledgor hereby agrees that a carbon,
         photographic or other reproduction of this Agreement or any such
         financing statement is sufficient for filing as a financing statement
         by the Agent without notice thereof to such Pledgor wherever the Agent
         in its discretion desires to file the same. In the event for any reason
         the law of any jurisdiction other than Illinois becomes or is
         applicable to the Collateral or any part thereof, or to any of the
         Obligations, each Pledgor agrees to execute and deliver all such
         agreements, assignments, instruments and documents and to do all such
         other things as the Agent in its sole discretion deems necessary or
         appropriate to preserve, protect and enforce the lien and security
         interest of the Agent under the law of such other jurisdiction to at
         least the same extent as such security interests would be protected
         under the UCC.

                   (c) If, as and when any Pledgor (x) delivers any securities
         for pledge hereunder in addition to those listed on Schedule A hereto
         or (y) pledges interests in any Partnership in addition to those listed
         on Schedule B hereto, the Pledgors shall furnish to the Agent a duly
         completed and executed amendment to such Schedule in substantially the
         form (with appropriate insertions) of Schedule D hereto reflecting the
         securities pledged hereunder after giving effect to such addition.

                   (d) None of the Collateral constitutes margin stock (within
         the meaning of Regulation U of the Board of Governors of the Federal
         Reserve System).

                   (e) On failure of any Pledgor to perform any of the
         agreements and covenants herein contained, the Agent may, at its
         option, perform the same and in so doing may expend such sums as the
         Agent may deem advisable in the performance thereof, including, without
         limitation, the payment of any taxes, liens and encumbrances,
         expenditures made in defending against any adverse claim, and all other
         expenditures which the Agent may be compelled to make by operation of
         law or which Agent may make by agreement or otherwise for the
         protection of the security hereof. All such sums 

                                      -5-
<PAGE>   6

         and amounts so expended shall be repayable by the Pledgors immediately
         without notice or demand, shall constitute additional Obligations
         secured hereunder and shall bear interest from the date said amounts
         are expended at the rate per annum (computed on the basis of a 365-day
         or 366-day year, as the case may be, for the actual number of days
         elapsed) determined by adding 2% to the Base Rate (such rate per annum
         as so determined being hereinafter referred to as the "Default Rate").
         No such performance of any covenant or agreement by the Agent on behalf
         of such Pledgor, and no such advancement or expenditure therefor, shall
         relieve such Pledgor of any default under the terms of this Agreement
         or in any way obligate the Agent or any Secured Creditor to take any
         further or future action with respect thereto. The Agent, in making any
         payment hereby authorized, may do so according to any bill, statement
         or estimate procured from the appropriate public office or holder of
         the claim to be discharged without inquiry into the accuracy of such
         bill, statement or estimate, or into the validity of any tax
         assessment, sale, forfeiture, tax lien or title or claim. The Agent, in
         performing any act hereunder, shall be the sole judge of whether the
         relevant Pledgor is required to perform the same under the terms of
         this Agreement. The Agent is hereby authorized to charge any depository
         or other account of any Pledgor maintained with the Agent for the
         amount of such sums and amounts so expended.

               Section 5.    Special Provisions Re: Stock Collateral.

                   (a) Each Pledgor has the right to vote the Pledged Securities
         and there are no restrictions upon the voting rights associated with,
         or the transfer of, any of the Pledged Securities, except as provided
         by federal and state laws applicable to the sale of securities
         generally.

                   (b) The certificates for all shares of the Pledged Securities
         shall be delivered by the relevant Pledgor to the Agent or any bailee
         of the Agent duly endorsed in blank for transfer or accompanied by an
         appropriate assignment or assignments or an appropriate undated stock
         power or powers, in every case sufficient to transfer title thereto.
         Each Pledgor acknowledges and agrees that National City Bank,
         Cleveland, Ohio ("NatCity") currently acts and shall continue to act as
         the Agent's bailee until such time as NatCity delivers the Pledged
         Securities and such stock powers to the Agent or any other bailee of
         the Agent. The Agent may at any time after the occurrence of an Event
         of Default cause to be transferred into its name or into the name of
         its nominee or nominees any and all of the Pledged Securities. The
         Agent shall at all times have the right to exchange the certificates
         representing the Pledged Securities for certificates of smaller or
         larger denominations.

                                      -6-
<PAGE>   7

                   (c) The Pledged Securities have been validly issued and are
         fully paid and non-assessable. There are no outstanding commitments or
         other obligations of the issuers of any of the Pledged Securities to
         issue, and no options, warrants or other rights of any individual or
         entity to acquire, any share of any class or series of capital stock of
         such issuers. The Pledged Securities listed and described on Schedule A
         attached hereto and delivered concurrently herewith to NatCity as the
         Agent's bailee constitute the percentage of the issued and outstanding
         capital stock of each series and class of the issuers thereof as set
         forth thereon owned by the relevant Pledgor. Each Pledgor further
         agrees that in the event any such issuer shall issue any additional
         capital stock of any series or class (whether or not entitled to vote)
         to such Pledgor or otherwise on account of its ownership interest
         therein, each Pledgor will forthwith pledge and deposit hereunder, or
         cause to be pledged and deposited hereunder, all such additional shares
         of such capital stock.

               Section 6. Special Provisions Re: Partnership Interest
         Collateral.

                   (a) Each Pledgor further warrants to and agrees with the
         Agent and the Secured Creditors as follows:

                            (i) that said Partnerships are valid and existing
                  entities of the type listed on Schedule B and are duly
                  organized and existing under applicable law;

                           (ii) that the Partnership Interest Collateral listed
                  and described on Schedule B attached hereto constitutes the
                  percentage of the equity interest in each Partnership set
                  forth thereon owned by the relevant Pledgor;

                          (iii) that the copies of the partnership agreements
                  (each such agreement being hereinafter referred to as
                  "Organizational Agreement") for the Partnerships heretofore
                  delivered to the Agent are true and correct copies thereof and
                  have not been amended or modified in any respect, except for
                  such amendments or modifications as are attached to the copies
                  thereof delivered to the Agent; and

                           (iv) that the Partnerships have no loans outstanding
                  to the Pledgors, and no Pledgor will borrow money from the
                  Partnerships.

                   (b) The Pledgors shall not, without the prior written consent
         of the Agent, consent to any amendment or modification to any of the
         Organizational Agreements which would in any manner adversely affect or
         impair the Partnership Interest Collateral or reduce or dilute the
         rights of the Pledgor with respect to any of the Partnerships, any of
         such done without such prior written consent to be null and void. The
         Pledgors shall promptly send to the Agent copies of all notices and
         communications with respect to each 




                                      -7-
<PAGE>   8

         Partnership alleging the existence of a default by an Pledgor in the
         performance of any of its obligations under any Organizational
         Agreement. Each Pledgor agrees that it will promptly notify the Agent
         of any litigation which might adversely affect such Pledgor or a
         Partnership or any of their respective properties and of any material
         adverse change in the operations, business properties, assets or
         conditions, financial or otherwise, of any Pledgor or any Partnership.
         Each Pledgor shall promptly perform all of its obligations under each
         Organizational Agreement. In the event any Pledgor fails to pay or
         perform any obligation arising under any Organizational Agreement or
         otherwise related to any Partnership, the Agent may, but need not, pay
         or perform such obligation at the expense and for the account of the
         Pledgors and all funds expended for such purposes shall constitute
         Obligations secured hereby which the Pledgors promise to pay to the
         Agent together with interest thereon at the Default Rate.

               Section 7. Voting Rights and Dividends. Unless and until an Event
of Default hereunder has occurred and thereafter until notified by the Agent
pursuant to Section 9(b) hereof:

                   (a) Each Pledgor shall be entitled to exercise all voting
         and/or consensual powers pertaining to the Collateral of such Pledgor,
         or any part thereof, for all purposes not inconsistent with the terms
         of this Agreement or any other document evidencing or otherwise
         relating to any of the Obligations.

                   (b) Each Pledgor shall be entitled to receive and retain all
         dividends and distributions in respect of the Collateral which are paid
         in cash of whatsoever nature; provided, however, that such dividends
         and distributions representing:

                            (i) stock or liquidating dividends or a distribution
                  or return of capital upon or in respect of the Pledged
                  Securities or any part thereof or resulting from a split-up,
                  revision or reclassification of the Pledged Securities or any
                  part thereof or received in addition to, in substitution of or
                  in exchange for the Pledged Securities or any part thereof as
                  a result of a merger, consolidation or otherwise, or

                           (ii) distributions in complete or partial liquidation
                  of any Partnership or the interest of such Pledgor therein,

         in each case, shall be paid, delivered or transferred, as appropriate,
         directly to the Agent immediately upon the receipt thereof by such
         Pledgor and shall, in the case of cash, be applied by the Agent to the
         satisfaction of Obligations in accordance with the provisions of
         Section 10 hereof, whether or not the same may then be due or otherwise
         adequately secured and shall, in the case of all other property,
         together with any cash received by the 



                                      -8-
<PAGE>   9

         Agent and not applied as aforesaid, be held by the Agent pursuant
         hereto as part of the Pledged Securities as additional Pledged
         Securities pledged under and subject to the terms of this Agreement; or

                   (c) In order to permit each Pledgor to exercise such voting
         and/or consensual powers which it is entitled to exercise under
         subsection (a) above and to receive such distributions which such
         Pledgor is entitled to receive and retain under subsection (b) above,
         the Agent will, if necessary, upon the written request of such Pledgor,
         from time to time execute and deliver to such Pledgor appropriate
         proxies and dividend orders.

               Section 8. Power of Attorney. Each Pledgor hereby appoints the
Agent, and each of its nominees, officers, agents, attorneys, and any other
person whom the Agent may designate, as such Pledgor's attorney-in-fact, with
full power and authority to ask, demand, collect, receive, receipt for, sue for,
compound and give acquittance for any and all sums or properties which may be or
become due, payable or distributable in respect of the Collateral or any part
thereof, with full power to settle, adjust or compromise any claim thereunder or
therefor as fully as such Pledgor could itself do, to endorse or sign the
Pledgor's name on any assignments, stock powers, or other instruments of
transfer and on any checks, notes, acceptances, money orders, drafts, and any
other forms of payment or security that may come into the Agent's possession and
on all documents of satisfaction, discharge or receipt required or requested in
connection therewith, and, in its discretion, to file any claim or take any
other action or proceeding, either in its own name or in the name of such
Pledgor, or otherwise, which the Agent may deem necessary or appropriate to
collect or otherwise realize upon all or any part of the Collateral, or effect a
transfer thereof, or which may be necessary or appropriate to protect and
preserve the right, title and interest of the Agent in and to such Collateral
and the security intended to be afforded hereby. Each Pledgor hereby ratifies
and approves all acts of any such attorney and agrees that neither the Agent nor
any such attorney will be liable for any such acts or omissions nor for any
error of judgment or mistake of fact or law other than such person's gross
negligence or willful misconduct. The Agent may file one or more financing
statements disclosing its security interest in all or any part of the Collateral
without any Pledgor's signature appearing thereon, and each Pledgor also hereby
grants the Agent a power of attorney to execute any such financing statements,
and any amendments or supplements thereto, on behalf of such Pledgor without
notice thereof to such Pledgor. The foregoing powers of attorney, being coupled
with an interest, are irrevocable until the Obligations have been fully
satisfied and any commitment of the Secured Creditors to extend credit
constituting Obligations to the Company has terminated; provided, however, that
the Agent agrees, as a personal covenant to the relevant Pledgor, not to
exercise the powers of attorney set forth in this Section unless an Event of
Default exists.



                                      -9-
<PAGE>   10

         Section 9. Defaults and Remedies. (a) The occurrence of any event or
the existence of any condition which is specified as an "Event of Default" under
the Credit Agreement shall constitute an "Event of Default" hereunder.

           (b) Upon the occurrence of any Event of Default, all rights of the
Pledgors to receive and retain the distributions which they are entitled to
receive and retain pursuant to Section 7(b) hereof shall, at the option of the
Agent cease and thereupon become vested in the Agent which, in addition to all
other rights provided herein or by law, shall then be entitled solely and
exclusively to receive and retain the distributions which the Pledgors would
otherwise have been authorized to retain pursuant to Section 7(b) hereof and all
rights of the Pledgors to exercise the voting and/or consensual powers which
they are entitled to exercise pursuant to Section 7(a) hereof shall, at the
option of the Agent, cease and thereupon become vested in the Agent which, in
addition to all other rights provided herein or by law, shall then be entitled
solely and exclusively to exercise all voting and other consensual powers
pertaining to the Collateral and to exercise any and all rights of conversion,
exchange or subscription and any other rights, privileges or options pertaining
thereto as if the Agent were the absolute owner thereof including, without
limitation, the right to exchange, at its discretion, the Collateral or any part
thereof upon the merger, consolidation, reorganization, recapitalization or
other readjustment of the respective issuer thereof or upon the exercise by or
on behalf of any such issuer or the Agent of any right, privilege or option
pertaining to the Collateral or any part thereof and, in connection therewith,
to deposit and deliver the Collateral or any part thereof with any committee,
depositary, transfer agent, registrar or other designated agency upon such terms
and conditions as the Agent may determine. In the event the Agent in good faith
believes any of the Collateral constitutes restricted securities within the
meaning of any applicable securities law, any disposition thereof in compliance
with such laws shall not render the disposition commercially unreasonable.

           (c) Upon the occurrence of any Event of Default, the Agent shall
have, in addition to all other rights provided herein or by law, the rights and
remedies of a secured party under the UCC (regardless of whether the UCC is the
law of the jurisdiction where the rights or remedies are asserted and regardless
of whether the UCC applies to the affected Collateral), and further the Agent
may, without demand and without advertisement, notice, hearing or process of
law, all of which each Pledgor hereby waives to the extent permitted by law, at
any time or times, sell and deliver any or all of the Collateral held by or for
it at public or private sale, at any securities exchange or broker's board or at
any of the Agent's offices or elsewhere, for cash, upon credit or otherwise, at
such prices and upon such terms as the Agent deems advisable, in its sole
discretion. In the exercise of any such remedies, the Agent may sell the
Collateral as a unit even though the sales price thereof may be in excess of the
amount remaining unpaid on the Obligations. Also, if less than all the
Collateral is sold, the Agent shall have no duty to marshal or apportion the
part of the Collateral so sold as between the Pledgors, or any of them, but may
sell and deliver any or all of the Collateral without regard to which of the
Pledgors are the 



                                      -10-
<PAGE>   11

owners thereof. In addition to all other sums due the Agent or any Secured
Creditor hereunder, each Pledgor shall pay the Agent and the Secured Creditors
all costs and expenses incurred by the Agent and such Secured Creditors,
including reasonable attorneys' fees and court costs, in obtaining, liquidating
or enforcing payment of Collateral or the Obligations or in the prosecution or
defense of any action or proceeding by or against the Agent, such Secured
Creditors or any Pledgor concerning any matter arising out of or connected with
this Agreement or the Collateral or the Obligations including, without
limitation, any of the foregoing arising in, arising under or related to a case
under the United States Bankruptcy Code (or any successor statute). Any
requirement of reasonable notice shall be met if such notice is personally
served on or mailed, postage prepaid, to the Pledgors in accordance with Section
14(b) hereof at least ten days before the time of sale or other event giving
rise to the requirement of such notice; provided, however, no notification need
be given to a Pledgor if such Pledgor has signed, after an Event of Default has
occurred, a statement renouncing any right to notification of sale or other
intended disposition. The Agent shall not be obligated to make any sale or other
disposition of the Collateral regardless of notice having been given. The Agent
or any Secured Creditor may be the purchaser at any sale or other disposition of
the Collateral or any part thereof. Each Pledgor hereby waives all of its rights
of redemption from any sale or other disposition of the Collateral or any part
thereof. The Agent may postpone or cause the postponement of the sale of all or
any portion of the Collateral by announcement at the time and place of such
sale, and such sale may, without further notice, be made at the time and place
to which the sale was postponed or the Agent may further postpone such sale by
announcement made at such time and place.

         EACH PLEDGOR AGREES THAT IF ANY PART OF THE COLLATERAL IS SOLD AT ANY
PUBLIC OR PRIVATE SALE, THE AGENT MAY ELECT TO SELL ONLY TO A BUYER WHO WILL
GIVE FURTHER ASSURANCES, SATISFACTORY IN FORM AND SUBSTANCE TO THE AGENT,
RESPECTING COMPLIANCE WITH THE REQUIREMENTS OF THE FEDERAL SECURITIES ACT OF
1933, AS AMENDED, AND A SALE SUBJECT TO SUCH CONDITION SHALL BE DEEMED
COMMERCIALLY REASONABLE.

         EACH PLEDGOR FURTHER AGREES THAT IN ANY SALE OF ANY PART OF THE
COLLATERAL, THE AGENT IS HEREBY AUTHORIZED TO COMPLY WITH ANY LIMITATION OR
RESTRICTION IN CONNECTION WITH SUCH SALE AS IT MAY BE ADVISED BY COUNSEL IS
NECESSARY IN ORDER TO AVOID ANY VIOLATION OF APPLICABLE LAW (INCLUDING, WITHOUT
LIMITATION, COMPLIANCE WITH SUCH PROCEDURES AS MAY RESTRICT THE NUMBER OF
PROSPECTIVE BIDDERS AND PURCHASERS AND/OR FURTHER RESTRICT SUCH PROSPECTIVE
BIDDERS OR PURCHASERS TO PERSONS WHO WILL REPRESENT AND AGREE THAT THEY ARE
PURCHASING FOR THEIR OWN ACCOUNT FOR INVESTMENT AND NOT WITH A VIEW TO THE
DISTRIBUTION OR RESALE OF SUCH COLLATERAL ), OR IN ORDER TO OBTAIN ANY REQUIRED
APPROVAL OF THE SALE OR OF THE PURCHASER BY ANY GOVERNMENTAL REGULATORY
AUTHORITY OR OFFICIAL, AND EACH PLEDGOR FURTHER AGREES THAT SUCH COMPLIANCE

                                      -11-
<PAGE>   12

SHALL NOT RESULT IN SUCH SALE BEING CONSIDERED OR DEEMED NOT TO HAVE BEEN MADE
IN A COMMERCIALLY REASONABLE MANNER, NOR SHALL THE AGENT BE LIABLE OR
ACCOUNTABLE TO ANY PLEDGOR FOR ANY DISCOUNT ALLOWED BY REASON OF THE FACT THAT
SUCH COLLATERAL IS SOLD IN COMPLIANCE WITH ANY SUCH LIMITATION OR RESTRICTION.

           (d) In the event the Agent shall sell any part of the Partnership
Interest Collateral at a foreclosure sale, each Pledgor hereby grants the
purchaser of such portion of the Partnership Interest Collateral to the fullest
extent of its capacity, the ability (but not the obligation) to become a partner
in the relevant Partnership (subject to the approval of the general partner of
the relevant Partnership, in the exercise of its sole discretion), in the place
and stead of such Pledgor. To exercise such right, the purchaser shall give
written notice to the relevant Partnership of its election to become a partner
in such Partnership. Following such election and giving of consent by all
necessary partners of the relevant Partnership as to the purchaser becoming a
partner, the purchaser shall have the right and powers and be subject to the
liabilities of a partner under the relevant Organizational Agreement and the
partnership act governing the Partnership.

           (e) Upon the occurrence and during the continuation of any Event of
Default, in addition to all other rights provided herein or by law, the Agent
shall have the right to cause all or any part of the Partnership Interest
Collateral of any of the Pledgors in any one or more of the Partnerships to be
redeemed and to cause a withdrawal, in whole or in part, of any Pledgor from any
Partnership or any of its Partnership Interest Collateral therein.

           (f) The powers conferred upon the Agent hereunder are solely to
protect its interest in the Collateral and shall not impose on it any duties to
exercise such powers. The Agent shall be deemed to have exercised reasonable
care in the custody and preservation of the Collateral in its possession if the
Collateral is accorded treatment substantially equivalent to that which the
Agent accords its own property, consisting of similar types securities, it being
understood, however, that the Agent shall have no responsibility for (i)
ascertaining or taking any action with respect to calls, conversions, exchanges,
maturities, tenders or other matters relating to any Collateral, whether or not
the Agent has or is deemed to have knowledge of such matters, (ii) taking any
necessary steps to preserve rights against any parties with respect to any
Collateral, or (iii) initiating any action to protect the Collateral or any part
thereof against the possibility of a decline in market value. This Agreement
constitutes an assignment of rights only and not an assignment of any duties or
obligations of the Pledgors in any way related to the Collateral, and the Agent
shall have no duty or obligation to discharge any such duty or obligation. By
its acceptance hereof, the Agent does not undertake to perform or discharge and
shall not be responsible or liable for the performance or discharge of any such
duties or responsibilities and shall not in any event become a "Substituted
Limited Partner" or words of like import (as defined in the relevant
Organizational Agreement) in the relevant Partnership. Neither the Agent or any
Secured Creditor, nor any party acting as attorney for the Agent or any Secured
Creditor, 



                                      -12-
<PAGE>   13

shall be liable hereunder for any acts or omissions or for any error of judgment
or mistake of fact or law other than such person's gross negligence or willful
misconduct.

           (g) Failure by the Agent to exercise any right, remedy or option
under this Agreement or any other agreement between any Pledgor and the Agent or
provided by law, or delay by the Agent in exercising the same, shall not operate
as a waiver; and no waiver shall be effective unless it is in writing, signed by
the party against whom such waiver is sought to be enforced and then only to the
extent specifically stated. The rights and remedies of the Agent and the Secured
Creditors under this Agreement shall be cumulative and not exclusive of any
other right or remedy which the Agent or the Secured Creditors may have. For
purposes of this Agreement, an Event of Default shall be construed as continuing
after its occurrence until the same is waived in writing by the Lenders or the
Required Lenders, as the case may be, in accordance with the Credit Agreement.

              Section 10. Application of Proceeds. The proceeds and avails of
the Collateral at any time received by the Agent during the existence of any
Event of Default shall, when received by the Agent in cash or its equivalent, be
applied by the Agent in reduction of, or as collateral security for, the
Obligations in accordance with the terms of the Credit Agreement. The Pledgors
shall remain liable to the Agent and the Secured Creditors for any deficiency.
Any surplus remaining after the full payment and satisfaction of the Obligations
shall be returned to the Pledgors, or to whomsoever the Agent reasonably
determines is lawfully entitled thereto.

              Section 11. Continuing Agreement. This Agreement shall be a
continuing agreement in every respect and shall remain in full force and effect
until all of the Obligations, both for principal and interest, have been fully
paid and satisfied and any commitment to extend constituting Obligations to and
of the Company shall have terminated. Upon such termination of this Agreement,
the Agent shall, upon the request and at the expense of the Pledgors, forthwith
release all its liens and security interests hereunder.

              Section 12. Primary Security; Obligations Absolute. The lien and
security herein created and provided for stand as direct and primary security
for the Obligations. No application of any sums received by the Agent in respect
of the Collateral or any disposition thereof to the reduction of the Obligations
or any portion thereof shall in any manner entitle any Pledgor to any right,
title or interest in or to the Obligations or any collateral security therefor,
whether by subrogation or otherwise, unless and until all Obligations have been
fully paid and satisfied and any commitments to extend credit constituting
Obligations to the Company shall have terminated. Each Pledgor acknowledges and
agrees that the lien and security hereby created and provided for are absolute
and unconditional and shall not in any manner be affected or impaired by any
acts or omissions whatsoever of the Agent, any Secured Creditor or any other
holder of any of the Obligations, and without limiting the generality of the
foregoing, the lien and security 




                                      -13-
<PAGE>   14

hereof shall not be impaired by any acceptance by the Agent, any Secured
Creditor or any other holder of any of the Obligations of any other security for
or guarantors upon any Obligations or by any failure, neglect or omission on the
part of the Agent, any Secured Creditor or any other holder of any of the
Obligations to realize upon or protect any of the Obligations or any collateral
security therefor. The lien and security hereof shall not in any manner be
impaired or affected by (and the Agent and the Secured Creditors, without notice
to anyone, are hereby authorized to make from time to time) any sale, pledge,
surrender, compromise, settlement, release, renewal, extension, indulgence,
alteration, substitution, exchange, change in, modification or disposition of
any of the Obligations, or of any collateral security therefor, or of any
guaranty thereof, or of any instrument or agreement setting forth the terms and
conditions pertaining to any of the foregoing. The Secured Creditors may at
their discretion at any time grant credit to the Company without notice to any
Pledgor in such amounts and on such terms as the Secured Creditors may elect
without in any manner impairing the lien and security hereby created and
provided for. In order to realize hereon and to exercise the rights granted the
Agent hereunder and under applicable law as against any Pledgor or any portion
of the Collateral in which any such Pledgor has rights, there shall be no
obligation on the part of the Agent, any Secured Creditor or any other holder of
any of the Obligations at any time to first resort for payment to the Company or
any other Pledgor or any other Person, its property or estate or to any guaranty
of the Obligations or any portion thereof or to resort to any other collateral
security, property, liens or any other rights or remedies whatsoever, and the
Agent shall have the right to enforce this Agreement as against any Pledgor or
any portion of the Collateral in which any such Pledgor has rights, irrespective
of whether or not other proceedings or steps are pending seeking resort to or
realization upon or from any of the foregoing.

              Section 13. The Agent. In acting under or by virtue of this
Agreement, Agent shall be entitled to all the rights, authority, privileges and
immunities provided in Section 10 of the Credit Agreement, all of which
provisions of said Section 10 are incorporated by reference herein with the same
force and effect as if set forth herein in their entirety. The Agent hereby
disclaims any representation or warranty to the Secured Creditors or any other
holders of the Obligations concerning the perfection of the liens and security
interests granted hereunder or in the value of the Collateral.

              Section 14. Miscellaneous. (a) This Agreement cannot be changed or
terminated orally. This Agreement shall create a continuing lien on and security
interest in the Collateral and shall be binding upon each Pledgor, its
successors and assigns, and shall inure, together with the rights and remedies
of the Agent and the Secured Creditors hereunder, to the benefit of the Agent
and the Secured Creditors, and their successors and assigns; provided, however,
that no Pledgor may assign its rights or delegate its duties hereunder without
the Agent's prior written consent. Without limiting the generality of the
foregoing, and subject to the provisions of the Credit Agreement, any Secured
Creditor may assign or otherwise transfer any indebtedness held 



                                      -14-

by it secured by this Agreement to any other person, and such other person shall
thereupon become vested with all the benefits in respect thereof granted to such
Secured Creditor herein or otherwise.

           (b) All communications provided for herein shall be in writing,
except as otherwise specifically provided for hereinabove, and shall be deemed
to have been given or made, if to any Pledgor when given to the Company in
accordance with Section 12.8 of the Credit Agreement, or if to the Agent or any
Lender, when given to such party in accordance with Section 12.8 of the Credit
Agreement.

           (c) No Secured Creditor shall have the right to institute any suit,
action or proceeding in equity or at law for the foreclosure or other
realization upon any Collateral subject to this Agreement or for the execution
of any trust or power hereof or for the appointment of a receiver, or for the
enforcement of any other remedy under or upon this Agreement; it being
understood and intended that no one or more of the Secured Creditors shall have
any right in any manner whatsoever to affect, disturb or prejudice the lien and
security interest of this Agreement by its or their action or to enforce any
right hereunder, and that all proceedings at law or in equity shall be
instituted, had and maintained by the Agent in the manner herein provided for
the benefit of the Secured Creditors.

           (d) In the event that any provision hereof shall be deemed to be
invalid by reason of the operation of any law or by reason of the interpretation
placed thereon by any court, this Agreement shall be construed as not containing
such provision, but only as to such locations where such law or interpretation
is operative, and the invalidity of such provision shall not affect the validity
of any remaining provision hereof, and any and all other provisions hereof which
are otherwise lawful and valid shall remain in full force and effect. Without
limiting the generality of the foregoing, in the event that this Agreement shall
be deemed to be invalid or otherwise unenforceable with respect to any Pledgor,
such invalidity or unenforceability shall not affect the validity of this
Agreement with respect to the other Pledgors.

           (e) This Agreement shall be deemed to have been made in the State of
Illinois and shall be governed by, and construed in accordance with, the laws of
the State of Illinois. All terms which are used in this Agreement which are
defined in the UCC shall have the same meanings herein as said terms do in the
UCC unless this Agreement shall otherwise specifically provide. The headings in
this Agreement are for convenience of reference only and shall not limit or
otherwise affect the meaning of any provision hereof.

           (f) This Agreement may be executed in any number of counterparts and
by different parties hereto on separate counterpart signature pages, each
constituting an original, but all together one and the same instrument. Each
Pledgor acknowledges that this Agreement is and 



                                      -15-
<PAGE>   16

shall be effective upon its execution and delivery by such Pledgor to the Agent,
and it shall not be necessary for the Agent to execute this Agreement or any
other acceptance hereof or otherwise to signify or express its acceptance
hereof.

           (g) In the event the Agent (with the consent of the requisite
Lenders) shall at any time in their discretion permit a substitution of Pledgors
hereunder or a party shall wish to become a Pledgor hereunder, such substituted
or additional Pledgor shall, upon executing an agreement in the form attached
hereto as Schedule E, become a party hereto and be bound by all the terms and
conditions hereof to the same extent as though such Pledgor had originally
executed this Agreement and, in the case of a substitution, in lieu of the
Pledgor being replaced. No such substitution shall be effective absent the
written consent of the Agent and the requisite Lenders nor shall it in any
manner affect the obligations of the other Pledgors hereunder.

           (h) THE AGENT AND THE PLEDGORS AGREE THAT ALL DISPUTES AMONG THEM
ARISING OUT OF, CONNECTED WITH, RELATED TO, OR INCIDENTAL TO THE RELATIONSHIP
ESTABLISHED AMONG THEM IN CONNECTION WITH THIS AGREEMENT, AND WHETHER ARISING IN
CONTRACT, TORT, EQUITY, OR OTHERWISE, SHALL BE RESOLVED ONLY BY STATE OR FEDERAL
COURTS LOCATED IN COOK COUNTY, ILLINOIS, BUT EACH OF THE AGENT AND THE PLEDGORS
ACKNOWLEDGE THAT ANY APPEALS FROM THOSE COURTS MAY HAVE TO BE HEARD BY A COURT
LOCATED OUTSIDE OF COOK COUNTY, ILLINOIS. EACH OF THE PLEDGORS WAIVES IN ALL
DISPUTES ANY OBJECTION THAT SUCH PLEDGOR MAY HAVE TO THE LOCATION OF THE COURT
CONSIDERING THE DISPUTE OR ANY OBJECTION THAT SUCH PLEDGOR MAY HAVE THAT ANY
OTHER PARTY HAS NOT BEEN JOINED IN SUCH PROCEEDING. EACH OF THE PLEDGORS AGREES
THAT THE AGENT SHALL HAVE THE RIGHT TO PROCEED AGAINST EACH AND ANY OF THE
PLEDGORS OR THEIR COLLATERAL IN A COURT IN ANY LOCATION TO ENABLE THE AGENT TO
REALIZE ON THE COLLATERAL, OR TO ENFORCE A JUDGMENT OR OTHER COURT ORDER ENTERED
IN FAVOR OF THE AGENT, WHETHER OR NOT PROCEEDING SEPARATELY AGAINST ANY PLEDGOR
AND ITS PROPERTY OR JOINTLY AGAINST THE COMPANY AND ANY ONE OR MORE OF THE
PLEDGORS AND THEIR PROPERTY. EACH OF THE PLEDGORS WAIVES ANY OBJECTION THAT IT
MAY HAVE TO THE LOCATION OF THE COURT IN WHICH THE AGENT HAS COMMENCED A
PROCEEDING DESCRIBED IN THIS PARAGRAPH.

with an equivalent proportion of such assigning Lender's obligation to make
advances under the Credit Agreement (each such assignment being hereinafter
referred to as an "Assignment"); and

         WHEREAS, in the event of each Assignment under the Credit Agreement,
the Borrower has agreed pursuant to the terms of the Credit Agreement to execute

estate and rights hereby granted shall cease, determine and be void and this
instrument shall be released by Mortgagee upon the written request and at the
expense of Mortgagor, otherwise to remain in full force and effect.

         It is expressly understood and agreed that the indebtedness hereby
secured will in no event exceed two hundred percent (200%) of (i) the total face
amount of the Notes and the Letters of Credit plus (ii) the total interest which
may hereafter accrue under the Notes and the Reimbursement Obligations (as
defined in the Credit Agreement) on such face amount plus (iii) any fees, costs
or expenses which may be payable hereunder or under the Credit Agreement.

         Mortgagor hereby covenants and agrees with Mortgagee as follows:

                    1. Payment of the Indebtedness. The indebtedness hereby
         secured will be promptly paid as and when the same becomes due without
         any relief whatever from valuation or appraisement laws of the State of
         Illinois.

                    2. Binding Obligation and Further Assurances. This Mortgage
         and all other documents, instruments and agreements executed in
         connection herewith are valid and binding obligations of Mortgagor,
         enforceable in accordance with their respective terms. Mortgagor will
         execute and deliver such further instruments and do such further acts
         as may be necessary or proper to carry out more effectively the purpose
         of this instrument and, without limiting the foregoing, to make subject
         to the lien hereof any property agreed to be subjected hereto or
         covered by the Granting Clauses hereof or intended so to be.

                    3. Ownership of the Mortgaged Premises. Mortgagor covenants
         and warrants that it is lawfully seized of and has good and marketable
         fee title to the Mortgaged Premises free and clear of all liens,
         charges and encumbrances whatsoever except those exceptions to title
         listed on Schedule II attached hereto (the "Permitted Exceptions") and
         Mortgagor has good right, full power and authority to convey, transfer
         and mortgage the same to Mortgagee for the uses and purposes set forth
         in this Mortgage; and Mortgagor will warrant and forever defend the
         title to the Mortgaged Premises subject to the Permitted Exceptions
         against all claims and demands whatsoever.

                    4. Possession. Provided no event of default has occurred and
         is continuing hereunder, Mortgagor shall be suffered and permitted to
         remain in full possession, enjoyment and control of the Mortgaged
         Premises, subject always to the observance and performance of the terms
         of this instrument.

                    5. Payment of Taxes. Mortgagor shall pay before any penalty
         attaches, all general taxes and all special taxes, special assessments,
         water, drainage and sewer charges and all other charges of any kind
         whatsoever, ordinary or extraordinary, which may be levied, assessed,
         imposed or charged on or against the Mortgaged Premises or any part
         thereof and which, if unpaid, might by law become a lien or charge upon
         the Mortgaged Premises or any part thereof, and shall, upon written
         request, exhibit to Mortgagee official receipts evidencing such
         payments, except that, unless and until foreclosure, distraint, sale or
         other similar proceedings shall have been commenced, no such charge or
         claim need be paid if being contested (except to the extent any full or
         partial payment shall be required by law), after notice to Mortgagee,
         by appropriate proceedings which shall operate to prevent the
         collection thereof or the sale or forfeiture of the Mortgaged Premises
         or any part thereof to satisfy the same, conducted in good faith and
         with due diligence and if Mortgagor shall have furnished such security,
         if any, as may be required in the proceedings or requested by
         Mortgagee.

                    6. Payment of Taxes on Notes, Letters of Credit, Mortgage or
         Interest of Mortgagee or Secured Creditors. Mortgagor agrees that if
         any tax, assessment or imposition upon this Mortgage or the
         indebtedness hereby secured or the Notes or any of the Letters of
         Credits or the interest of Mortgagee or any Secured Creditor in the
         Mortgaged Premises or upon Mortgagee or any Secured Creditor by reason
         of or as a holder of any of the foregoing (including, without
         limitation, excise taxes, but excepting therefrom any income tax on
         interest payments on the principal portion of the indebtedness hereby
         secured imposed by the United States or any state) is levied, assessed
         or charged, then, unless all such taxes are paid by Mortgagor to, for
         or on behalf of Mortgagee or any Secured Creditor as they become due
         and payable (which Mortgagor agrees to do upon demand of Mortgagee, to
         the extent permitted by law), or Mortgagee or any Secured Creditor is
         reimbursed for any such sum advanced by Mortgagee, all sums hereby
         secured shall become immediately due and payable, at the option of
         Mortgagee upon 30 days' notice to Mortgagor, notwithstanding anything
         contained herein or in any law heretofore or hereafter enacted,
         including any provision thereof forbidding Mortgagor from making any
         such payment. Mortgagor agrees to exhibit to Mortgagee, upon request,
         official receipts showing payment of all taxes and charges which
         Mortgagor is required to pay hereunder.

                    7. Recordation and Payment of Taxes and Expenses Incident
         Thereto. Mortgagor will maintain and preserve the lien of this Mortgage
         until all indebtedness hereby secured has been paid and satisfied in
         full. Without limiting the foregoing, Mortgagor will cause this
         Mortgage, all mortgages supplemental hereto and any financing statement
         or other notice of a security interest required by Mortgagee at all
         times to be kept, recorded and filed at its own expense in such manner
         and in such places as may be 


                                      -8-

<PAGE>   9

         required by law for the recording and filing or for the rerecording and
         refiling of a mortgage, security interest, assignment or other lien or
         charge upon the Mortgaged Premises, or any part thereof, in order fully
         to preserve and protect the rights of Mortgagee hereunder and, without
         limiting the foregoing, Mortgagor will pay or reimburse Mortgagee and
         any Secured Creditor for the payment of any and all taxes, fees or
         other charges incurred in connection with any such recordation or
         rerecordation, including any documentary stamp tax or tax imposed upon
         the privilege of having this instrument or any instrument issued
         pursuant hereto recorded.

                    8. Insurance. Mortgagor will, at its expense, keep all
         buildings, improvements, equipment and other property now or hereafter
         constituting part of the Mortgaged Premises insured against loss or
         damage by fire, lightning, windstorm, explosion and such other risks as
         are usually included under extended coverage policies, or which are
         usually insured against by companies similarly situated conducting
         similar businesses and owning like properties, in amount sufficient to
         prevent Mortgagor, Mortgagee or the Secured Creditors from becoming a
         co-insurer of any partial loss under applicable policies and in any
         event not less than the then full insurable value (actual replacement
         value without deduction for physical depreciation) thereof, as
         determined at the request of Mortgagee and at Mortgagor's expense by
         the insurer or insurers or by an expert approved by Mortgagee, all
         under insurance policies payable, in case of loss or damage, to
         Mortgagee (and if Mortgagee so requests, naming Mortgagee and the
         Secured Creditors as additional insureds therein), such rights to be
         evidenced by the usual standard non-contributory form of mortgage
         clause to be attached to each policy. Mortgagor shall not carry
         separate insurance concurrent in kind or form and contributing in the
         event of loss, with any insurance required hereby. Mortgagor shall also
         obtain and maintain public liability, property damage and workmen's
         compensation insurance in each case in form and content satisfactory to
         Mortgagee and in amounts as are customarily carried by owners of like
         property and approved by Mortgagee. Mortgagor shall also obtain and
         maintain such other insurance with respect to the Mortgaged Premises in
         such amounts and against such insurable hazards as Mortgagee from time
         to time may require, including, without limitation, boiler and
         machinery insurance, insurance against flood risks for any improvements
         located in a flood plain when and to the extent obtainable from the
         United States Government or any agency thereof, and insurance against
         loss of rent due to fire and risks now or hereafter embraced by
         so-called "extended coverage". All insurance required hereby shall be
         maintained with good and responsible insurance companies satisfactory
         to Mortgagee and shall not provide for any deductible amount in excess
         of $250,000 not approved in writing by Mortgagee, shall provide that
         any losses shall be payable notwithstanding any act or negligence of
         Mortgagor, shall provide that no cancellation thereof shall be
         effective until at least thirty days after receipt by Mortgagor and
         Mortgagee of written notice thereof, and shall be 


                                      -9-
<PAGE>   10

         satisfactory to Mortgagee in all other respects. Upon the execution of
         this Mortgage and thereafter not less than 15 days prior to the
         expiration date of any policy delivered pursuant to this instrument,
         Mortgagor will deliver to Mortgagee certificates evidencing the policy
         or renewal policy, as the case may be, required by this instrument,
         bearing notations evidencing the payment of all premiums. In the event
         of foreclosure, Mortgagor authorizes and empowers Mortgagee to effect
         insurance upon the Mortgaged Premises in amounts aforesaid for a period
         covering the time of redemption from foreclosure sale provided by law,
         and if necessary therefor to cancel any or all existing insurance
         policies.

                    9.     Damage to or Destruction of Mortgaged Premises.

                            (a) Notice. In case of any material damage to or
                  destruction of the Mortgaged Premises or any part thereof,
                  Mortgagor shall promptly give written notice thereof to
                  Mortgagee, generally describing the nature and extent of such
                  damage or destruction.

                            (b) Restoration. In case of any damage to or
                  destruction of the Mortgaged Premises or any part thereof,
                  Mortgagor, whether or not the insurance proceeds, if any,
                  received on account of such damage or destruction shall be
                  sufficient for the purpose, at Mortgagor's expense, will
                  promptly commence and complete (subject to unavoidable delays
                  occasioned by strikes, lockouts, acts of God, inability to
                  obtain labor or materials, governmental restrictions and
                  similar causes beyond the reasonable control of Mortgagor) the
                  restoration, replacement or rebuilding of the Mortgaged
                  Premises as nearly as possible to its value, condition and
                  character immediately prior to such damage or destruction,
                  provided that any part of the Mortgaged Premises so damaged or
                  destroyed need not be restored, replaced or rebuilt if (i)
                  prior to its damage or destruction, it had become
                  uneconomical, obsolete or worn out or (ii) it is not necessary
                  for or of importance to the proper conduct of the Mortgagor's
                  business in the ordinary course.

                            (c) Adjustment of Loss. Mortgagor hereby authorizes
                  Mortgagee, at Mortgagee's option, to adjust and compromise any
                  losses under any insurance afforded at any time after the
                  occurrence and during the continuation of any event of default
                  hereunder or any event which with the lapse of time, the
                  giving of notice, or both, would constitute an event of
                  default hereunder (herein, a "default"), but unless Mortgagee
                  elects to adjust the losses as aforesaid, said adjustment
                  and/or compromise shall be made by Mortgagor, subject to final


                                      -10-
<PAGE>   11

                  approval of Mortgagee (regardless of whether or not a default
                  or event of default hereunder shall have occurred) in the case
                  of losses exceeding $250,000.

                            (d) Application of Insurance Proceeds. Net insurance
                  proceeds (except in cases where (i) the amount payable in
                  respect of any one loss, when combined with amounts paid in
                  respect of all losses incurred during any calendar year, is
                  less than $250,000 and (ii) an event of default hereunder
                  shall not have occurred and be continuing, in which case the
                  amount payable in respect of such loss may be received by
                  Mortgagor and need not be applied toward the payment of the
                  amount owing on the indebtedness hereby secured or for the
                  restoration of the Mortgaged Premises damaged or destroyed)
                  received by Mortgagee under the provisions of this Mortgage or
                  any instruments supplemental hereto or thereto or under any
                  policy or policies of insurance covering the Mortgaged
                  Premises or any part thereof shall first be applied toward the
                  payment of the amount owing on the indebtedness hereby secured
                  in such order of application as Mortgagee may elect whether or
                  not the same may then be due or be otherwise adequately
                  secured; provided, however, that such proceeds shall be made
                  available for the restoration of the portion of the Mortgaged
                  Premises damaged or destroyed if written application for such
                  use is made within thirty (30) days of receipt of such
                  proceeds and the following conditions are satisfied: (i)
                  Mortgagor has in effect business interruption insurance
                  covering the income to be lost during the restoration period
                  as a result of the damage or destruction to the Mortgaged
                  Premises or provides Mortgagee with other evidence
                  satisfactory to it that Mortgagor has cash resources
                  sufficient to pay its obligations during the restoration
                  period; (ii) no event of default, or event which, with the
                  lapse of time, the giving of notice, or both, would constitute
                  an event of default hereunder, shall have occurred or be
                  continuing (and if such an event shall occur during
                  restoration Mortgagee may, at its election, apply any
                  insurance proceeds then remaining in its hands to the
                  reduction of the indebtedness evidenced by the NOTES and the
                  other indebtedness hereby secured); (iii) Mortgagor shall have
                  submitted to Mortgagee plans and specifications for the
                  restoration which shall be satisfactory to it; (iv) Mortgagor
                  shall submit to Mortgagee fixed price contracts with good and
                  responsible contractors and materialmen covering all work and
                  materials necessary to complete restoration and providing for
                  a total completion price not in excess of the amount of
                  insurance proceeds available for restoration, or, if a
                  deficiency shall exist, Mortgagor shall have deposited the
                  amount of such deficiency with Mortgagee and (v) Mortgagor
                  shall have obtained a waiver of the right of subrogation from
                  any insurer under such policies of insurance who at that time
                  claims that no liability exists as to Mortgagor or the insured
                  under such policies. Any insurance proceeds to be released
                  pursuant to the foregoing 


                                      -11-
<PAGE>   12

                   provisions may at the option of Mortgagee be disbursed from
                   time to time as restoration progresses to pay for restoration
                   work completed and in place and such disbursements may at
                   Mortgagee's option be made directly to Mortgagor or to or
                   through any contractor or materialman to whom payment is due
                   or to or through a construction escrow to be maintained by a
                   title insurer acceptable to Mortgagee. Mortgagee may impose
                   such further conditions upon the release of insurance
                   proceeds (including the receipt of title insurance) as are
                   customarily imposed by prudent construction lenders to insure
                   the completion of the restoration work free and clear of all
                   liens or claims for lien. All title insurance charges and
                   other costs and expenses paid to or for the account of
                   Mortgagor in connection with the release of such insurance
                   proceeds shall constitute so much additional indebtedness
                   hereby secured to be payable upon demand with interest at the
                   Default Rate. Mortgagee may deduct any such costs and
                   expenses from insurance proceeds at any time standing in its
                   hands. If Mortgagor fails to request that insurance proceeds
                   be applied to the restoration of the improvements or if
                   Mortgagor makes such a request but fails to complete
                   restoration within a reasonable time, Mortgagee shall have
                   the right, but not the duty, to restore or rebuild said
                   Mortgaged Premises or any part thereof for or on behalf of
                   Mortgagor in lieu of applying said proceeds to the
                   indebtedness hereby secured and for such purpose may do all
                   necessary acts, including using funds deposited by Mortgagor
                   as aforesaid and advancing additional funds for the purpose
                   of restoration, all such additional funds to constitute part
                   of the indebtedness hereby secured payable upon demand with
                   interest at the Default Rate.

                   10. Eminent Domain. Mortgagor acknowledges that Condemnation
         Awards have been assigned to Mortgagee, which awards Mortgagee is
         hereby irrevocably authorized to collect and receive, and to give
         appropriate receipts and acquittances therefor, and at Mortgagee's
         option, to apply the same toward the payment of the amount owing on
         account of the indebtedness hereby secured in such order of application
         as Mortgagee may elect and whether or not the same may then be due and
         payable or otherwise adequately secured; provided, however, that a
         Condemnation Award in respect of any taking of a portion (but not all
         or any material portion) of the Mortgaged Premises shall be made
         available for the restoration of such Mortgaged Premises in the same
         manner and subject to the same conditions as are imposed on the release
         of insurance proceeds set forth in Section 9(d) hereof as if the
         Mortgaged Premises so taken were destroyed and the Condemnation Award
         for such taking was actually insurance proceeds in respect of the
         Mortgaged Premises so deemed as having been destroyed. In the event
         that any proceeds of a Condemnation Award shall be made available to
         Mortgagor for restoring the Mortgaged Premises so taken, Mortgagor
         hereby covenants to promptly commence and complete such restoration of
         the Mortgaged Premises as nearly as possible 


                                      -12-
<PAGE>   13

         to its value, condition and character immediately prior to such taking.
         Mortgagor covenants and agrees that Mortgagor will give Mortgagee
         immediate notice of the actual or threatened commencement of any
         proceedings under condemnation or eminent domain affecting all or any
         material part of the Mortgaged Premises including any easement therein
         or appurtenance thereof or severance and consequential damage and
         change in grade of streets, and will deliver to Mortgagee copies of any
         and all papers served in connection with any such proceedings.
         Mortgagor further covenants and agrees to make, execute and deliver to
         Mortgagee, at any time or times upon request, free, clear and
         discharged of any encumbrances of any kind whatsoever, any and all
         further assignments and/or instruments deemed necessary by Mortgagee
         for the purpose of validly and sufficiently assigning all awards and
         other compensation heretofore and hereafter to be made to Mortgagor for
         any taking, either permanent or temporary, under any such proceeding.

                   11. Construction, Repair, Waste, Etc. Mortgagor agrees that
         no building or other improvement on the Mortgaged Premises and
         constituting a part thereof shall be materially altered, removed or
         demolished nor shall any material fixtures or appliances on, in or
         about said buildings or improvements be severed, removed, sold or
         mortgaged, without the consent of Mortgagee, and in the event of the
         demolition or destruction in whole or in part of any of the fixtures or
         articles of personal property covered hereby, Mortgagor covenants that
         the same will be replaced promptly by similar fixtures and articles of
         personal property at least equal in quality and condition to those
         replaced, free from any security interest in or encumbrance thereon or
         reservation of title thereto other than liens permitted by the Credit
         Agreement and the Permitted Exceptions; provided, however, that
         Mortgagor may alter, remove or demolish any such building, improvement,
         fixture or appliance, and need not replace any such fixtures or
         personal property, in each case to the extent such action (i) is
         desirable to the proper conduct of the business of Mortgagor in the
         ordinary course as presently conducted and otherwise in the best
         interest of Mortgagor, (ii) does not impair the overall value or
         utility of the Mortgaged Premises and Mortgagor's other related
         properties as an integrated facility, (iii) does not decrease the
         efficiency or capacity of the Mortgaged Premises and (iv) does not
         impair the rights and benefits under this Mortgage of the Secured
         Creditors. Mortgagor further agrees to permit, commit or suffer no
         material waste, impairment or deterioration of the Mortgaged Premises
         or any part thereof; to keep and maintain said Mortgaged Premises and
         every part thereof in good working condition (ordinary wear and tear
         excepted); to effect such repairs as Mortgagee may reasonably require
         and from time to time to make all needful and proper replacements and
         additions so that said buildings, fixtures, machinery and appurtenances
         will, at all times, be in good working condition (ordinary wear and
         tear excepted), fit and proper for the respective purposes for which
         they were originally erected or installed; to comply with all statutes,
         orders, requirements or decrees relating 


                                      -13-
<PAGE>   14

         to the Mortgaged Premises by any federal, state or municipal authority
         if the failure to comply with such statutes, orders, requirements or
         decrees could have a material adverse effect on the Mortgaged Premises
         or the business or financial condition of the Mortgagor; to observe and
         comply with all conditions and requirements necessary to preserve and
         extend any and all rights, licenses, permits (including, but not
         limited to, zoning variances, special exceptions and non-conforming
         uses), privileges, franchises and concessions which are applicable to
         the Mortgaged Premises or which have been granted to or contracted for
         by Mortgagor in connection with any existing or presently contemplated
         use of the Mortgaged Premises or any part thereof and not to initiate
         or acquiesce in any changes to or terminations of any of the foregoing
         or of zoning classifications affecting the use to which the Mortgaged
         Premises or any part thereof may be put without the prior written
         consent of Mortgagee; and to make no material alterations in or
         improvements or additions to the Mortgaged Premises except as required
         by governmental authority or as permitted by Mortgagee. Mortgagor will
         not lease the Mortgaged Premises or any material part thereof without
         the prior written consent of Mortgagee, which consent shall not be
         unreasonably withheld.

                   12. Liens and Encumbrances. Mortgagor will not, without the
         prior written consent of Mortgagee, directly or indirectly, create or
         suffer to be created or to remain and will discharge or promptly cause
         to be discharged any mortgage, lien, encumbrance or charge on, pledge
         of, or conditional sale or other title retention agreement with respect
         to, the Mortgaged Premises or any part thereof, whether superior or
         subordinate to the lien hereof, except for this instrument, liens
         permitted by the Credit Agreement and the Permitted Exceptions.

                   13. Right of Mortgagee to Perform Mortgagor's Covenants, Etc.
         If Mortgagor shall fail to make any payment or perform any act required
         to be made or performed hereunder, Mortgagee, without waiving or
         releasing any obligation or default, may (but shall be under no
         obligation to) at any time after notice to the Mortgagor make such
         payment or perform such act for the account and at the expense of
         Mortgagor, and may enter upon the Mortgaged Premises or any part
         thereof for such purpose and take all such action thereon as, in the
         opinion of Mortgagee, may be reasonably necessary or appropriate
         therefor. All sums so paid by Mortgagee and all reasonable costs and
         expenses (including without limitation attorney's fees and expenses) so
         incurred, together with interest thereon from the date of payment or
         incurrence at the Default Rate, shall constitute so much additional
         indebtedness hereby secured and shall be paid by Mortgagor to Mortgagee
         on demand. Mortgagee in making any payment authorized under this
         Section relating to taxes or assessments may do so according to any
         bill, statement or estimate procured from the appropriate public office
         without inquiry into the 


                                      -14-
<PAGE>   15

         accuracy of such bill, statement or estimate or into the validity of
         any tax assessment, sale, forfeiture, tax lien or title or claim
         thereof.

                   14. After-Acquired Property. Any and all property hereafter
         acquired which is of the kind or nature herein provided, or intended to
         be and become subject to the lien hereof, shall ipso facto, and without
         any further conveyance, assignment or act on the part of Mortgagor,
         become and be subject to the lien of this Mortgage as fully and
         completely as though specifically described herein; but nevertheless
         Mortgagor shall from time to time, if requested by Mortgagee, execute
         and deliver any and all such further assurances, conveyances and
         assignments as Mortgagee may reasonably require for the purpose of
         expressly and specifically subjecting to the lien of this Mortgage all
         such property.

                   15. Inspection by Mortgagee. Mortgagee, any Secured Creditor
         and their respective representatives shall have the right to inspect
         the Mortgaged Premises at all reasonable times, and access thereto
         shall be permitted for that purpose; provided, however, that prior to
         the occurrence of any Default or Event of Default hereunder, any such
         access or inspection shall only be required during the Mortgagor's
         normal business hours and shall only be permitted with at least 24
         hours advance notice.

                   16. Reports on Mortgaged Premises. Mortgagor will furnish to
         Mortgagee or any Secured Creditor such information and data with
         respect to the Mortgaged Premises as Mortgagee or such Secured Creditor
         may reasonably request.

                   17. Subrogation. Mortgagor acknowledges and agrees that
         Mortgagee shall be subrogated to any lien discharged out of the
         proceeds of the loan evidenced by any Note or out of any advance by
         Mortgagee hereunder, irrespective of whether or not any such lien may
         have been released of record.

                   18. Events of Default. Any one or more of the following shall
         constitute an event of default hereunder:

                       (a) Failure to pay when due any indebtedness hereby
                   secured; or

                       (b) Any event occurs or condition exists which is
                   specified as an Event of Default under the Credit Agreement;
                   or

                       (c) The Mortgaged Premises or any material part thereof
                   shall be sold, transferred, or conveyed, whether voluntarily
                   or involuntarily, by operation of law or otherwise, except
                   for sales of obsolete, worn out or unusable fixtures or
                   personal property which are concurrently replaced (unless the
                   Mortgagor, in the 


                                      -15-
<PAGE>   16

                  exercise of its commercially reasonable judgment deems such
                  replacement not necessary or impractical and such failure to
                  replace would cause no material adverse change in the
                  Mortgaged Premises) with similar fixtures or personal
                  property at least equal in quality and condition to those
                  sold and owned by Mortgagor free of any lien, charge or
                  encumbrance other than the lien hereof; or

                       (d) Any indebtedness secured by a lien or charge on
                  the Mortgaged Premises or any part thereof is not paid when
                  due after the expiration of applicable grace periods and the
                  giving of applicable notices, if any (unless such indebtedness
                  is being contested in good faith by appropriate proceedings
                  which prevent the enforcement of the matter under contest and
                  adequate reserves have been established therefor), or
                  proceedings are commenced to foreclose or otherwise realize
                  upon any such lien or charge or to have a receiver appointed
                  for the property subject thereto or to place the holder of
                  such indebtedness or its representative in possession thereof;
                  or

                       (e) The Mortgaged Premises is abandoned.

                   19. Remedies. When any event of default has happened and is
         continuing (regardless of the pendency of any proceeding which has or
         might have the effect of preventing Mortgagor from complying with the
         terms of this instrument and of the adequacy of the security for the
         Notes, Letters of Credit and the other indebtedness hereby secured) and
         in addition to such other rights as may be available under applicable
         law, but subject at all times to any mandatory legal requirements:

                       (a) Acceleration. As and to the extent expressly
                   permitted by the Credit Agreement, Mortgagee may, by written
                   notice to Mortgagor, declare the Notes and all unpaid
                   indebtedness hereby secured, including the reimbursement
                   obligations of the Mortgagor in connection with any Letters
                   of Credit, including any interest then accrued thereon, to be
                   forthwith due and payable, whereupon the same shall become
                   and be forthwith due and payable, without other notice or
                   demand of any kind.

                       (b) Uniform Commercial Code. Mortgagee shall, with
                   respect to any part of the Mortgaged Premises constituting
                   property of the type in respect of which realization on a
                   lien or security interest granted therein is governed by the
                   Uniform Commercial Code, have all the rights, options and
                   remedies of a secured party under the Uniform Commercial Code
                   of Illinois, including without limitation, the right to the
                   possession of any such property, or any part thereof, and the
                   right to enter without legal process any premises where any
                   such property 


                                      -16-
<PAGE>   17

                  may be found. Any requirement of said Code for reasonable
                  notification shall be met by mailing written notice to
                  Mortgagor at its address above set forth at least 10 Business
                  Days prior to the sale or other event for which such notice
                  is required. The expenses of retaking, selling, and otherwise
                  disposing of said property, including reasonable attorney's
                  fees and legal expenses incurred in connection therewith,
                  shall constitute so much additional indebtedness hereby
                  secured and shall be payable upon demand with interest at the
                  Default Rate. 

                        (c) Foreclosure. Mortgagee may proceed to protect
                  and enforce the rights of Mortgagee or Secured Creditors
                  hereunder (i) by any action at law, suit in equity or other
                  appropriate proceedings, whether for the specific performance
                  of any agreement contained herein, or for an injunction
                  against the violation of any of the terms hereof, or in aid of
                  the exercise of any power granted hereby or by law, or (ii) by
                  the foreclosure of this Mortgage.

                        (d) Appointment of Receiver. Mortgagee shall, as a
                  matter of right, without notice and without giving bond to
                  Mortgagor or anyone claiming by, under or through it, and
                  without regard to the solvency or insolvency of Mortgagor or
                  the then value of the Mortgaged Premises, be entitled to have
                  a receiver appointed of all or any part of the Mortgaged
                  Premises and the rents, issues and profits thereof, with such
                  power as the court making such appointment shall confer, and
                  Mortgagor hereby consents to the appointment of such receiver
                  and shall not oppose any such appointment. Any such receiver
                  may, to the extent permitted under applicable law, without
                  notice, enter upon and take possession of the Mortgaged
                  Premises or any part thereof by force, summary proceedings,
                  ejectment or otherwise, and may remove Mortgagor or other
                  persons and any and all property therefrom, and may hold,
                  operate and manage the same and receive all earnings, income,
                  rents, issues and proceeds accruing with respect thereto or
                  any part thereof, whether during the pendency of any
                  foreclosure or until any right of redemption shall expire or
                  otherwise.

                        (e) Taking Possession, Collecting Rents, Etc.
                  Mortgagee may enter and take possession of the Mortgaged
                  Premises or any part thereof and manage, operate, insure,
                  repair and improve the same and take any action which, in
                  Mortgagee's reasonable judgment, is necessary or proper to
                  conserve the value of the Mortgaged Premises. Mortgagee may
                  also take possession of, and for these purposes use, any and
                  all personal property contained in the Mortgaged Premises and
                  used in the operation, rental or leasing thereof or any part
                  thereof. Mortgagee shall be entitled to collect and receive
                  all earnings, revenues, rents, issues and profits of the
                  Mortgaged Premises or any part thereof (and for such purpose


                                      -17-
<PAGE>   18

                  Mortgagor does hereby irrevocably constitute and appoint
                  Mortgagee its true and lawful attorney-in-fact for it and in
                  its name, place and stead to receive, collect and receipt for
                  all of the foregoing, Mortgagor irrevocably acknowledging that
                  any payment made to Mortgagee hereunder shall be a good
                  receipt and acquittance against Mortgagor to the extent so
                  made) and to apply same to the reduction of the indebtedness
                  hereby secured. The right to enter and take possession of the
                  Mortgaged Premises and use any personal property therein, to
                  manage, operate and conserve the same, and to collect the
                  rents, issues and profits thereof, shall be in addition to all
                  other rights or remedies of Mortgagee hereunder or afforded by
                  law, and may be exercised concurrently therewith or
                  independently thereof. The reasonable expenses (including any
                  receiver's fees, counsel fees, costs and agent's compensation)
                  incurred pursuant to the powers herein contained shall be so
                  much additional indebtedness hereby secured which Mortgagor
                  promises to pay upon demand together with interest at the
                  Default Rate. Mortgagee shall not be liable to account to
                  Mortgagor for any action taken pursuant hereto other than to
                  account for any rents actually received by Mortgagee. Without
                  taking possession of the Mortgaged Premises, Mortgagee may, in
                  the event the Mortgaged Premises becomes vacant or is
                  abandoned, take such steps as it deems appropriate to protect
                  and secure the Mortgaged Premises (including hiring watchmen
                  therefor) and all reasonable costs incurred in so doing shall
                  constitute so much additional indebtedness hereby secured
                  payable upon demand with interest thereon at the Default Rate.

                  20. Waiver of Right to Redeem From Sale - Waiver of
         Appraisement, Valuation, Etc. Mortgagor shall not and will not apply
         for or avail itself of any appraisement, valuation, stay, extension or
         exemption laws, or any so-called "Moratorium Laws", now existing or
         hereafter enacted in order to prevent or hinder the enforcement or
         foreclosure of this Mortgage, but hereby waives the benefit of such
         laws. Mortgagor for itself and all who may claim through or under it
         waives any and all right to have the property and estates comprising
         the Mortgaged Premises marshalled upon any foreclosure of the lien
         hereof and agrees that any court having jurisdiction to foreclose such
         lien may order the Mortgaged Premises sold as an entirety. In the event
         of any sale made under or by virtue of this instrument, the whole of
         the Mortgaged Premises may be sold in one parcel as an entirety or in
         separate lots or parcels at the same or different times, all as the
         Mortgagee may determine. Mortgagee or any Secured Creditor shall have
         the right to become the purchaser at any sale made under or by virtue
         of this instrument; and Mortgagee or any Secured Creditor so purchasing
         at any such sale shall have the right to be credited upon the amount of
         the bid made therefor by Mortgagee or such Secured Creditor with the
         amount payable to Mortgagee or such Secured Creditor, as the case may
         be, out of the net proceeds of such sale, and upon compliance with the


                                      -18-
<PAGE>   19

         terms of sale, may hold, retain and possess and dispose of such
         property in its own absolute right without further accountability. In
         the event of any such sale, the Notes, the Reimbursement Obligations
         and the other indebtedness hereby secured, if not previously due, shall
         be and become immediately due and payable without demand or notice of
         any kind. Mortgagor hereby waives any and all rights of redemption
         prior to or from sale under any order or decree of foreclosure pursuant
         to rights herein granted, on behalf of Mortgagor, and each and every
         person acquiring any interest in, or title to the Mortgaged Premises
         described herein subsequent to the date of this Mortgage, and on behalf
         of all other persons to the extent permitted by applicable law.

                   21. Costs and Expenses of Foreclosure. In any suit to
         foreclose the lien hereof there shall be allowed and included as
         additional indebtedness in the decree for sale all reasonable
         expenditures and expenses which may be paid or incurred by or on behalf
         of Mortgagee or any Secured Creditor for attorney's fees, appraiser's
         fees, outlays for documentary and expert evidence, stenographic
         charges, publication costs and costs (which may be estimated as to
         items to be expended after the entry of the decree) of procuring all
         such abstracts of title, title searches and examination, guarantee
         policies, Torrens certificates and similar data and assurances with
         respect to title as Mortgagee or any Secured Creditor may deem to be
         reasonably necessary either to prosecute any foreclosure action or to
         evidence to the bidder at any sale pursuant thereto the true condition
         of the title to or the value of the Mortgaged Premises, all of which
         expenditures shall become so much additional indebtedness hereby
         secured which Mortgagor agrees to pay and all of such shall be
         immediately due and payable with interest thereon from the date of
         expenditure until paid at the Default Rate.

                   22. Application of Proceeds. The proceeds and avails of the
         Mortgaged Premises, including without limitation the proceeds of any
         foreclosure sale of the Mortgaged Premises or of any sale of property
         pursuant to Section l9(b) hereof, shall, when received by Mortgagee in
         cash or its equivalent, be applied by the Mortgagee as set forth in
         Section 3.5 of the Credit Agreement. Mortgagor shall remain liable to
         Mortgagee and the Secured Creditors for any deficiency. Any surplus
         remaining after the full payment and satisfaction of the foregoing
         shall be returned to Mortgagor or to whomsoever a court of competent
         jurisdiction shall determine to be entitled thereto.

                   23. Deficiency Decree. If at any foreclosure proceeding the
         Mortgaged Premises shall be sold for a sum less than the total amount
         of indebtedness for which judgment is therein given, the judgment
         creditor shall be entitled to the entry of a deficiency decree against
         Mortgagor and against the property of Mortgagor for the amount of such
         deficiency; and Mortgagor does hereby irrevocably consent to the
         appointment of a receiver for the Mortgaged Premises and the property
         of Mortgagor and 


                                      -19-
<PAGE>   20

         of the rents, issues and profits thereof after such sale and until such
         deficiency decree is satisfied in full.

                   24. Mortgagee's Remedies Cumulative - No Waiver. No remedy or
         right of Mortgagee shall be exclusive of but shall be cumulative and in
         addition to every other remedy or right now or hereafter existing at
         law or in equity or by statute or otherwise. No delay in the exercise
         or omission to exercise any remedy or right accruing on any default
         shall impair any such remedy or right or be construed to be a waiver of
         any such default or acquiescence therein, nor shall it affect any
         subsequent default of the same or a different nature. Every such remedy
         or right may be exercised concurrently or independently, and when and
         as often as may be deemed expedient by Mortgagee.

                   25. Mortgagee Party to Suits. Mortgagee shall have the power
         and authority (but not the duty) to institute and maintain any suits
         and proceedings as Mortgagee may deem advisable (a) to prevent any
         impairment of the Mortgaged Premises by any acts which may be unlawful
         or which violate the terms of this Mortgage, (b) to preserve or protect
         its interest in the Mortgaged Premises or (c) to restrain the
         enforcement of or compliance with any legislation or other governmental
         enactment, rule or order that may be unconstitutional or otherwise
         invalid, if the enforcement of or compliance with such enactment, rule
         or order might impair the security hereunder or be prejudicial to
         Mortgagee's or Secured Creditor's interest. If Mortgagee or any Secured
         Creditor shall be made a party to or shall intervene in any action or
         proceeding affecting the Mortgaged Premises or the title thereto or the
         interest of Mortgagee or any Secured Creditor under this Mortgage
         (including probate and bankruptcy proceedings), or if Mortgagee or any
         Secured Creditor employs an attorney to collect any or all of the
         indebtedness hereby secured or to enforce any of the terms hereof or
         realize hereupon or to protect the lien hereof, or if Mortgagee or any
         Secured Creditor shall incur any costs or expenses in preparation for
         the commencement of any foreclosure proceedings or for the defense of
         any threatened suit or proceeding which might affect the Mortgaged
         Premises or the security hereof, whether or not any such foreclosure or
         other suit or proceeding shall be actually commenced, then in any such
         case, Mortgagor agrees to pay to Mortgagee or such Secured Creditor, as
         the case may be, immediately and without demand, all reasonable costs,
         charges, expenses and attorney's fees incurred by Mortgagee or such
         Secured Creditor in any such case, and the same shall constitute so
         much additional indebtedness hereby secured payable upon demand with
         interest at the Default Rate.

                   26. Modifications Not to Affect Lien. Mortgagee, without
         notice to anyone (except the Lenders), and without regard to the
         consideration, if any, paid therefor, or the presence of other liens on
         the Mortgaged Premises, may at the direction of the Lenders release any
         part of the Mortgaged Premises or any person liable for any of the

                                      -20-
<PAGE>   21

         indebtedness hereby secured, may extend the time of payment of any of
         the indebtedness hereby secured and may grant waivers or other
         indulgences with respect hereto and thereto, and may agree with
         Mortgagor to modifications to the terms and conditions contained herein
         or otherwise applicable to any of the indebtedness hereby secured
         (including modifications in the rates of interest applicable thereto),
         without in any way affecting or impairing the liability of any party
         liable upon any of the indebtedness hereby secured or the priority of
         the lien of this Mortgage upon all of the Mortgaged Premises not
         expressly released, and any party acquiring any direct or indirect
         interest in the Mortgaged Premises shall take same subject to all of
         the provisions hereof.

                   27. Revolving Credit Loan. This Mortgage is given to secure,
         among other things, a revolving credit loan and shall secure not only
         presently existing indebtedness under the Credit Agreement but also
         future advances, or otherwise, as are made within twenty (20) years
         from the date hereof, to the same extent as if such future advances
         were made on the date of the execution of this Mortgage, although there
         may be no advance made at the time of execution of this Mortgage and
         although there may be no indebtedness hereby secured outstanding at the
         time any advance is made. The lien of this Mortgage shall be valid as
         to all indebtedness hereby secured, including future advances, from the
         time of its filing for record in the recorder's or registrar's office
         of the county in which the Mortgaged Premises are located. The total
         amount of indebtedness hereby secured may increase or decrease from
         time to time, but the total unpaid balance of indebtedness hereby
         secured (including disbursements which Mortgagee may make under this
         Mortgage, the Credit Agreement or any other documents related thereto)
         at any one time outstanding shall not exceed a maximum principal amount
         of One Hundred Million Dollars ($100,000,000) plus interest thereon and
         any disbursements made for payment of taxes, special assessments or
         insurance on the Mortgaged Premises and interest on such disbursements
         (all such indebtedness being hereinafter referred to as the "maximum
         amount secured hereby"). This Mortgage shall be valid and have priority
         over all subsequent liens and encumbrances, including statutory liens,
         excepting solely taxes and assessments levied on the Mortgaged
         Premises, to the extent of the maximum amount secured hereby.

                   28. Notices. All communications provided for herein shall be
         in writing (including cable, telecopy or telex) and shall be given to
         the relevant party at its address, telecopier number or telex number

                   30. Condition of Property. Mortgagor warrants and represents
         that, to the best of its knowledge, except as heretofore disclosed in
         writing to the Mortgagee, the Mortgaged Premises, including all
         personal property, is free from contamination, that there has not been

         liquid, which is prohibited, controlled or regulated under applicable

         environment, and that the Mortgaged Premises does not contain, or is
         not affected by, except to the extent not in violation of Environmental
         Laws: (i) asbestos, (ii) urea formaldehyde foam insulation, (iii)
         polychlorinated biphenyls (PCBs), (iv) underground storage tanks, (v)
         landfills, land disposals or dumps.

                   31. Notice of Environmental Problem. Except as heretofore
         disclosed in writing to the Mortgagee, Mortgagor represents and
         warrants that to the best of its knowledge it has not given, nor should
         it give, nor has it received, any notice, letter, citation, order,
         warning, complaint, inquiry, claim or demand that: (i) Mortgagor has
         violated, or is about to violate, any federal, state, regional, county
         or local environmental, health or safety statute, law, rule,
         regulation, ordinance, judgment or order on the Mortgaged Premises;

         products or derivatives, or other hydrocarbons) on the Mortgaged
         Premises; (iv) any of the Mortgagor's property or assets are subject to
         a lien in favor of any governmental body for any liability, costs or

         regulation arising from or costs incurred by such governmental entity
         in response to a release of a hazardous substance (including, without
         limitation, petroleum, its by-products or derivatives, or other
         hydrocarbons). In the event that Mortgagor receives any notice of the
         type described in this Section, Mortgagor shall promptly provide a copy
         to Mortgagee, and in no event, later than fifteen (15) days from
         Mortgagor's receipt or submission thereof.

                   32. Use of Property and Facilities. Mortgagor represents and
         warrants that to the best of its knowledge, except as heretofore
         disclosed in writing to the Mortgagee, it has never in the past
         engaged in, and agrees that in the future it shall not conduct, any
         business, operations or activity on the Mortgaged Premises, or employ
         or use the personal property or facilities, to manufacture, use,
         generate, treat, store, transport or dispose of any hazardous
         substance (including, without limitation, petroleum, its derivatives
         or by-products, or other hydrocarbons), or any other substance which
         is prohibited, controlled or regulated under applicable law, or which
         poses a threat or nuisance to safety, health or the environment,
         including, without limitation, any business, operation or activity
         which would cause Mortgagor, its property or facilities, to be in
         violation of the Resource Conservation and Recovery Act of 1976, as

         state statute providing for financial responsibility for cleanup for
         the release or threatened release of substances provided for
         thereunder. The provisions of this Section shall apply to all real and
         personal property, without limitation, owned or controlled by
         Mortgagor or its subsidiaries.

                   33. Partial Invalidity. All rights, powers and remedies
         provided herein are intended to be limited to the extent necessary so
         that they will not render this Mortgage invalid, unenforceable or not
         entitled to be recorded, registered or filed under any applicable law.
         If any term of this Mortgage shall be held to be invalid, illegal or
         unenforceable, the validity and enforceability of the other terms of
         this Mortgage shall in no way be affected thereby.

                   34. Agent. Mortgagee has been appointed as agent pursuant to
         the Credit Agreement. In acting under or by virtue of this Mortgage,
         Mortgagee shall be entitled to all the rights, authority, privileges
         and immunities provided in Section 10 of the Credit Agreement, all of
         which provisions of said Section 10 are incorporated by reference
         herein with the same force and effect as if set forth herein. Mortgagee
         hereby disclaims any representation or warranty to Secured Creditors
         concerning the perfection of the security interest granted hereunder or
         the value of the Mortgaged Premises.

                                      -24-
<PAGE>   25

                   35. Restrictions on Secured Creditors' Right to Enforce. No
         Secured Creditor shall have the right to institute any suit, action or
         proceeding in equity or at law for the foreclosure of this Mortgage or
         for the execution of any trust or power hereof or for the appointment
         of a receiver, or for the enforcement of any other remedy under or upon
         this Mortgage; it being understood and intended that no one or more of
         the Secured Creditors shall have any right in any manner whatsoever to
         affect, disturb or prejudice the lien of this Mortgage by its or their
         action or to enforce any right hereunder, and that all proceedings at
         law or in equity shall be instituted, had and maintained by the
         Mortgagee in the manner herein provided and for the ratable benefit of
         the Secured Creditors.

                   36. Successors and Assigns. Whenever any of the parties
         hereto is referred to, such reference shall be deemed to include the
         successors and assigns of such party; and all the covenants, promises
         and agreements in this Mortgage contained by or on behalf of Mortgagor,
         or by or on behalf of Mortgagee or Secured Creditors, shall bind and
         inure to the benefit of the respective successors and assigns of such
         parties, whether so expressed or not. Without limiting the generality
         of the foregoing, and subject to the provisions of Sections 12.14 and
         12.15 of the Credit Agreement, any Lender may assign or otherwise
         transfer any indebtedness held by it secured by this Mortgage to any
         other person or entity, and such other person or entity shall thereupon
         become vested with all the benefits in respect thereof granted to such
         Lender herein or otherwise, subject, however, to the provisions of the
         Credit Agreement.

                   37. Default Rate. For purposes of this Mortgage, "Default
         Rate" shall mean the rate per annum as set forth in Section 2.1 of the
         Credit Agreement.

                   38. Liens Absolute, Etc. Mortgagor acknowledges and agrees
         that the lien and security interest hereby created and provided for are
         absolute and unconditional and shall not in any manner be affected or
         impaired by any acts or omissions whatsoever of Mortgagee or any other
         holder of any of the indebtedness hereby secured, and without limiting
         the generality of the foregoing, the lien and security hereof shall not
         be impaired by any acceptance by Mortgagee or any other holder of any
         of the indebtedness hereby secured of any other security for or
         guarantors upon any of the indebtedness hereby secured or by any
         failure, neglect or omission on the part of Mortgagee or any other
         holder of any of the indebtedness hereby secured to realize upon or
         protect any of the indebtedness hereby secured or any collateral or
         security therefor. The lien and security interest hereof shall not in
         any manner be impaired or affected by (and Mortgagee, without notice to
         anyone, is hereby authorized to make from time to time) any sale,
         pledge, surrender, compromise, settlement, release, renewal, extension,
         indulgence, alteration, substitution, exchange, change in, modification
         or disposition of any of the indebtedness hereby secured, or of any
         collateral or security therefor, or of any guaranty 


                                      -25-
<PAGE>   26

         thereof, or of any instrument or agreement setting forth the terms and
         conditions pertaining to any of the foregoing. The Secured Creditors
         may at their discretion at any time grant credit to the Borrower
         without notice to Mortgagor in such amounts and on such terms as such
         Secured Creditors may elect without in any manner impairing the lien
         and security interest created and provided for herein. In order to
         realize hereon and to exercise the rights granted Mortgagee hereby and
         under applicable law, there shall be no obligation on the part of
         Mortgagee or any other holder of any of the indebtedness hereby secured
         at any time to first resort for payment to the Borrower or to any
         guaranty of any of the indebtedness hereby secured or any portion
         thereof or to resort to any other collateral, security, property, liens
         or any other rights or remedies whatsoever, and Mortgagee shall have
         the right to enforce this Mortgage irrespective of whether or not other
         proceedings or steps seeking resort to or realization upon or from any
         of the foregoing are pending.

                   39. Direct and Primary Security - No Subrogation. The lien
         and security interest herein created and provided for stand as direct
         and primary security for the Notes as well as for any of the other
         indebtedness hereby secured. No application of any sums received by
         Mortgagee in respect of the Mortgaged Premises or any disposition
         thereof to the reduction of the indebtedness hereby secured or any part
         thereof shall in any manner entitle Mortgagor to any right, title or
         interest in or to the indebtedness hereby secured or any collateral or
         security therefor, whether by subrogation or otherwise, unless and
         until all indebtedness hereby secured has been fully paid and satisfied
         and any commitment of the Secured Creditors to extend credit to
         Mortgagor or to the Borrower shall have expired.

                   40. Multisite Real Estate Transaction. Mortgagor acknowledges
         that this Mortgage is one of a number of other mortgages and deeds of
         trusts and other security documents dated of even date herewith (such
         mortgages, deeds of trust and other security documents dated of even
         date herewith and any supplements or amendments thereto and any other
         mortgages, deeds of trust or security documents securing the
         indebtedness hereby secured are collectively called the "Other
         Mortgages") which secure the indebtedness hereby secured. Mortgagor
         agrees that the lien of this Mortgage shall be absolute and
         unconditional and shall not in any manner be affected or impaired by
         any acts or omissions whatsoever of Mortgagee and, without limiting the
         generality of the foregoing, the lien hereof shall not be impaired by
         any acceptance by Mortgagee of any security for or guarantors upon any
         of the indebtedness hereby secured, or by any failure, neglect or
         omission on the part of the Mortgagee to realize upon or protect any of
         the indebtedness hereby secured or any collateral security therefor
         including the Other Mortgages. The lien hereof shall not in any manner
         be impaired or affected by any release (except as to the property
         released) sale, pledge, surrender, compromise, 


                                      -26-

         settlement, renewal, extension, indulgence, alteration, changing,
         modification or disposition of any of the indebtedness hereby secured
         or of any of the collateral security therefor, including without
         limitation the Other Mortgages or of any guarantee thereof, and
         Mortgagee may at its discretion foreclose, exercise any power of sale,
         or exercise any other remedy available to it under any or all of the
         Other Mortgages without first exercising or enforcing any of its rights
         and remedies hereunder. Such exercise of Mortgagee's rights and
         remedies under any or all of the Other Mortgages shall not in any
         manner impair the indebtedness hereby secured or the lien of this
         Mortgage and any exercise of the rights or remedies of Mortgagee
         hereunder shall not impair the lien of any of the Other Mortgages or
         any of Mortgagee's rights and remedies thereunder. The undersigned
         specifically consents and agrees that Mortgagee may exercise its rights
         and remedies hereunder and under the Other Mortgages separately or
         concurrently and in any order that it may deem appropriate.

                   41. Prior Mortgage. Upon the execution and delivery of this
         Mortgage by the Mortgagor hereunder, this Mortgage shall supersede all
         provisions of the Prior Mortgage as of such date. The Mortgagor hereby
         agrees that, notwithstanding the execution and delivery of this
         Mortgage, the lien and security interest created and provided for under
         the Prior Mortgage continue in effect under and pursuant to the terms
         of this Mortgage for the benefit of all of the Obligations secured
         hereby. Nothing herein contained shall in any manner affect or impair
         the priority of the liens and security interests created and provided
         for by the Prior Mortgage as to the indebtedness and obligations which
         would otherwise be secured hereby prior to giving effect to this
         Mortgage.

                   42. Headings. The headings in this instrument are for
         convenience of reference only and shall not limit or otherwise affect
         the meaning of any provision hereof.

                   43. Changes, Etc. This instrument and the provisions hereof
         may be changed, waived, discharged or terminated only by an instrument
         in writing signed by the party against which enforcement of the change,
         waiver, discharge or termination is sought.

                   44. Governing Law. The creation of this Mortgage, the
         perfection of the lien or security interest in the Mortgaged Premises,
         and the rights and remedies of the Mortgagee with respect to the
         Mortgaged Premises, as provided herein and by the laws of the state in
         which the Mortgaged Premises is located, shall be governed by and
         construed in accordance with the internal laws of the state in which

         attaches, all general taxes and all special taxes, special assessments,
         water, drainage and sewer charges and all other charges of any kind
         whatsoever, ordinary or extraordinary, which may be levied, assessed,
         imposed or charged on or against the Mortgaged Premises or any part
         thereof and which, if unpaid, might by law become a lien or charge upon
         the Mortgaged Premises or any part thereof, and shall, upon written
         request, exhibit to Mortgagee official receipts evidencing such
         payments, except that, unless and until foreclosure, distraint, sale or
         other similar proceedings shall have been commenced, no such charge or
         claim need be paid if being contested (except to the extent any full or
         partial payment shall be required by law), after notice to Mortgagee,
         by appropriate proceedings which shall operate to prevent the
         collection thereof or the sale or forfeiture of the Mortgaged Premises
         or any part thereof to satisfy the same, conducted in good faith and
         with due diligence and if Mortgagor shall have furnished such security,
         if any, as may be required in the proceedings or requested by
         Mortgagee.

                    6. Payment of Taxes on Notes, Letters of Credit, Mortgage or
         Interest of Mortgagee or Secured Creditors. Mortgagor agrees that if
         any tax, assessment or imposition upon this Mortgage or the
         indebtedness hereby secured or the Notes or any of the Letters of
         Credits or the interest of Mortgagee or any Secured Creditor in the
         Mortgaged Premises or upon Mortgagee or any Secured Creditor by reason
         of or as a 




                                      -7-

         holder of any of the foregoing (including, without limitation, excise
         taxes, but excepting therefrom any income tax on interest payments on
         the principal portion of the indebtedness hereby secured imposed by the
         United States or any state) is levied, assessed or charged, then,
         unless all such taxes are paid by Mortgagor to, for or on behalf of
         Mortgagee or any Secured Creditor as they become due and payable (which
         Mortgagor agrees to do upon demand of Mortgagee, to the extent
         permitted by law), or Mortgagee or any Secured Creditor is reimbursed
         for any such sum advanced by Mortgagee, all sums hereby secured shall
         become immediately due and payable, at the option of Mortgagee upon 30
         days' notice to Mortgagor, notwithstanding anything contained herein or
         in any law heretofore or hereafter enacted, including any provision
         thereof forbidding Mortgagor from making any such payment. Mortgagor
         agrees to exhibit to Mortgagee, upon request, official receipts showing
         payment of all taxes and charges which Mortgagor is required to pay
         hereunder.

                    7. Recordation and Payment of Taxes and Expenses Incident
         Thereto. Mortgagor will maintain and preserve the lien of this Mortgage
         until all indebtedness hereby secured has been paid and satisfied in
         full. Without limiting the foregoing, Mortgagor will cause this
         Mortgage, all mortgages supplemental hereto and any financing statement
         or other notice of a security interest required by Mortgagee at all
         times to be kept, recorded and filed at its own expense in such manner
         and in such places as may be required by law for the recording and
         filing or for the rerecording and refiling of a mortgage, security
         interest, assignment or other lien or charge upon the Mortgaged
         Premises, or any part thereof, in order fully to preserve and protect
         the rights of Mortgagee hereunder and, without limiting the foregoing,
         Mortgagor will pay or reimburse Mortgagee and any Secured Creditor for
         the payment of any and all taxes, fees or other charges incurred in
         connection with any such recordation or rerecordation, including any
         documentary stamp tax or tax imposed upon the privilege of having this
         instrument or any instrument issued pursuant hereto recorded.

                    8. Insurance. Mortgagor will, at its expense, keep all
         buildings, improvements, equipment and other property now or hereafter
         constituting part of the Mortgaged Premises insured against loss or
         damage by fire, lightning, windstorm, explosion and such other risks as
         are usually included under extended coverage policies, or which are
         usually insured against by companies similarly situated conducting
         similar businesses and owning like properties, in amount sufficient to
         prevent Mortgagor, Mortgagee or the Secured Creditors from becoming a
         co-insurer of any partial loss under applicable policies and in any
         event not less than the then full insurable value (actual replacement
         value without deduction for physical depreciation) thereof, as
         determined at the request of Mortgagee and at Mortgagor's expense by
         the insurer or insurers or by an expert approved by Mortgagee, all
         under insurance policies payable, in case of loss or 




                                      -8-
<PAGE>   9

         damage, to Mortgagee (and if Mortgagee so requests, naming Mortgagee
         and the Secured Creditors as additional insureds therein), such rights
         to be evidenced by the usual standard non-contributory form of mortgage
         clause to be attached to each policy. Mortgagor shall not carry
         separate insurance concurrent in kind or form and contributing in the
         event of loss, with any insurance required hereby. Mortgagor shall also
         obtain and maintain public liability, property damage and workmen's
         compensation insurance in each case in form and content satisfactory to
         Mortgagee and in amounts as are customarily carried by owners of like
         property and approved by Mortgagee. Mortgagor shall also obtain and
         maintain such other insurance with respect to the Mortgaged Premises in
         such amounts and against such insurable hazards as Mortgagee from time
         to time may require, including, without limitation, boiler and
         machinery insurance, insurance against flood risks for any improvements
         located in a flood plain when and to the extent obtainable from the
         United States Government or any agency thereof, and insurance against
         loss of rent due to fire and risks now or hereafter embraced by
         so-called "extended coverage". All insurance required hereby shall be
         maintained with good and responsible insurance companies satisfactory
         to Mortgagee and shall not provide for any deductible amount in excess
         of $250,000 not approved in writing by Mortgagee, shall provide that
         any losses shall be payable notwithstanding any act or negligence of
         Mortgagor, shall provide that no cancellation thereof shall be
         effective until at least thirty days after receipt by Mortgagor and
         Mortgagee of written notice thereof, and shall be satisfactory to
         Mortgagee in all other respects. Upon the execution of this Mortgage
         and thereafter not less than 15 days prior to the expiration date of
         any policy delivered pursuant to this instrument, Mortgagor will
         deliver to Mortgagee certificates evidencing the policy or renewal
         policy, as the case may be, required by this instrument, bearing
         notations evidencing the payment of all premiums. In the event of
         foreclosure, Mortgagor authorizes and empowers Mortgagee to effect
         insurance upon the Mortgaged Premises in amounts aforesaid for a period
         covering the time of redemption from foreclosure sale provided by law,
         and if necessary therefor to cancel any or all existing insurance
         policies.

                    9.     Damage to or Destruction of Mortgaged Premises.

                            (a) Notice. In case of any material damage to or
                  destruction of the Mortgaged Premises or any part thereof,
                  Mortgagor shall promptly give written notice thereof to
                  Mortgagee, generally describing the nature and extent of such
                  damage or destruction.

                            (b) Restoration. In case of any damage to or
                  destruction of the Mortgaged Premises or any part thereof,
                  Mortgagor, whether or not the insurance proceeds, if any,
                  received on account of such damage or destruction shall be



                                      -9-
<PAGE>   10

                  sufficient for the purpose, at Mortgagor's expense, will
                  promptly commence and complete (subject to unavoidable delays
                  occasioned by strikes, lockouts, acts of God, inability to
                  obtain labor or materials, governmental restrictions and
                  similar causes beyond the reasonable control of Mortgagor) the
                  restoration, replacement or rebuilding of the Mortgaged
                  Premises as nearly as possible to its value, condition and
                  character immediately prior to such damage or destruction,
                  provided that any part of the Mortgaged Premises so damaged or
                  destroyed need not be restored, replaced or rebuilt if (i)
                  prior to its damage or destruction, it had become
                  uneconomical, obsolete or worn out or (ii) it is not necessary
                  for or of importance to the proper conduct of the Mortgagor's
                  business in the ordinary course.

                            (c) Adjustment of Loss. Mortgagor hereby authorizes
                  Mortgagee, at Mortgagee's option, to adjust and compromise any
                  losses under any insurance afforded at any time after the
                  occurrence and during the continuation of any event of default
                  hereunder or any event which with the lapse of time, the
                  giving of notice, or both, would constitute an event of
                  default hereunder (herein, a "default"), but unless Mortgagee
                  elects to adjust the losses as aforesaid, said adjustment
                  and/or compromise shall be made by Mortgagor, subject to final
                  approval of Mortgagee (regardless of whether or not a default
                  or event of default hereunder shall have occurred) in the case
                  of losses exceeding $250,000.

                            (d) Application of Insurance Proceeds. Net insurance
                  proceeds (except in cases where (i) the amount payable in
                  respect of any one loss, when combined with amounts paid in
                  respect of all losses incurred during any calendar year, is
                  less than $250,000 and (ii) an event of default hereunder
                  shall not have occurred and be continuing, in which case the
                  amount payable in respect of such loss may be received by
                  Mortgagor and need not be applied toward the payment of the
                  amount owing on the indebtedness hereby secured or for the
                  restoration of the Mortgaged Premises damaged or destroyed)
                  received by Mortgagee under the provisions of this Mortgage or
                  any instruments supplemental hereto or thereto or under any
                  policy or policies of insurance covering the Mortgaged
                  Premises or any part thereof shall first be applied toward the
                  payment of the amount owing on the indebtedness hereby secured
                  in such order of application as Mortgagee may elect whether or
                  not the same may then be due or be otherwise adequately
                  secured; provided, however, that such proceeds shall be made
                  available for the restoration of the portion of the Mortgaged
                  Premises damaged or destroyed if written application for such
                  use is made within thirty (30) days of receipt of such
                  proceeds and the following conditions are satisfied: (i)
                  Mortgagor has in effect business interruption insurance
                  covering the income to be lost during the 



                                      -10-
<PAGE>   11

                  restoration period as a result of the damage or destruction to
                  the Mortgaged Premises or provides Mortgagee with other
                  evidence satisfactory to it that Mortgagor has cash resources
                  sufficient to pay its obligations during the restoration
                  period; (ii) no event of default, or event which, with the
                  lapse of time, the giving of notice, or both, would constitute
                  an event of default hereunder, shall have occurred or be
                  continuing (and if such an event shall occur during
                  restoration Mortgagee may, at its election, apply any
                  insurance proceeds then remaining in its hands to the
                  reduction of the indebtedness evidenced by the NOTES and the
                  other indebtedness hereby secured); (iii) Mortgagor shall have
                  submitted to Mortgagee plans and specifications for the
                  restoration which shall be satisfactory to it; (iv) Mortgagor
                  shall submit to Mortgagee fixed price contracts with good and
                  responsible contractors and materialmen covering all work and
                  materials necessary to complete restoration and providing for
                  a total completion price not in excess of the amount of
                  insurance proceeds available for restoration, or, if a
                  deficiency shall exist, Mortgagor shall have deposited the
                  amount of such deficiency with Mortgagee and (v) Mortgagor
                  shall have obtained a waiver of the right of subrogation from
                  any insurer under such policies of insurance who at that time
                  claims that no liability exists as to Mortgagor or the insured
                  under such policies. Any insurance proceeds to be released
                  pursuant to the foregoing provisions may at the option of
                  Mortgagee be disbursed from time to time as restoration
                  progresses to pay for restoration work completed and in place
                  and such disbursements may at Mortgagee's option be made
                  directly to Mortgagor or to or through any contractor or
                  materialman to whom payment is due or to or through a
                  construction escrow to be maintained by a title insurer
                  acceptable to Mortgagee. Mortgagee may impose such further
                  conditions upon the release of insurance proceeds (including
                  the receipt of title insurance) as are customarily imposed by
                  prudent construction lenders to insure the completion of the
                  restoration work free and clear of all liens or claims for
                  lien. All title insurance charges and other costs and expenses
                  paid to or for the account of Mortgagor in connection with the
                  release of such insurance proceeds shall constitute so much
                  additional indebtedness hereby secured to be payable upon
                  demand with interest at the Default Rate. Mortgagee may deduct
                  any such costs and expenses from insurance proceeds at any
                  time standing in its hands. If Mortgagor fails to request that
                  insurance proceeds be applied to the restoration of the
                  improvements or if Mortgagor makes such a request but fails to
                  complete restoration within a reasonable time, Mortgagee shall
                  have the right, but not the duty, to restore or rebuild said
                  Mortgaged Premises or any part thereof for or on behalf of
                  Mortgagor in lieu of applying said proceeds to the
                  indebtedness hereby secured and for such purpose may do all
                  necessary acts, including using funds deposited by Mortgagor
                  as aforesaid and advancing additional funds for the purpose of
                  restoration, all such 




                                      -11-
<PAGE>   12

                  additional funds to constitute part of the indebtedness hereby
                  secured payable upon demand with interest at the Default Rate.

                   10. Eminent Domain. Mortgagor acknowledges that Condemnation
         Awards have been assigned to Mortgagee, which awards Mortgagee is
         hereby irrevocably authorized to collect and receive, and to give
         appropriate receipts and acquittances therefor, and at Mortgagee's
         option, to apply the same toward the payment of the amount owing on
         account of the indebtedness hereby secured in such order of application
         as Mortgagee may elect and whether or not the same may then be due and
         payable or otherwise adequately secured; provided, however, that a
         Condemnation Award in respect of any taking of a portion (but not all
         or any material portion) of the Mortgaged Premises shall be made
         available for the restoration of such Mortgaged Premises in the same
         manner and subject to the same conditions as are imposed on the release
         of insurance proceeds set forth in Section 9(d) hereof as if the
         Mortgaged Premises so taken were destroyed and the Condemnation Award
         for such taking was actually insurance proceeds in respect of the
         Mortgaged Premises so deemed as having been destroyed. In the event
         that any proceeds of a Condemnation Award shall be made available to
         Mortgagor for restoring the Mortgaged Premises so taken, Mortgagor
         hereby covenants to promptly commence and complete such restoration of
         the Mortgaged Premises as nearly as possible to its value, condition
         and character immediately prior to such taking. Mortgagor covenants and
         agrees that Mortgagor will give Mortgagee immediate notice of the
         actual or threatened commencement of any proceedings under condemnation
         or eminent domain affecting all or any material part of the Mortgaged
         Premises including any easement therein or appurtenance thereof or
         severance and consequential damage and change in grade of streets, and
         will deliver to Mortgagee copies of any and all papers served in
         connection with any such proceedings. Mortgagor further covenants and
         agrees to make, execute and deliver to Mortgagee, at any time or times
         upon request, free, clear and discharged of any encumbrances of any
         kind whatsoever, any and all further assignments and/or instruments
         deemed necessary by Mortgagee for the purpose of validly and
         sufficiently assigning all awards and other compensation heretofore and
         hereafter to be made to Mortgagor for any taking, either permanent or
         temporary, under any such proceeding.

                   11. Construction, Repair, Waste, Etc. Mortgagor agrees that
         no building or other improvement on the Mortgaged Premises and
         constituting a part thereof shall be materially altered, removed or
         demolished nor shall any material fixtures or appliances on, in or
         about said buildings or improvements be severed, removed, sold or
         mortgaged, without the consent of Mortgagee, and in the event of the
         demolition or destruction in whole or in part of any of the fixtures or
         articles of personal property covered hereby, Mortgagor covenants that
         the same will be replaced promptly by similar fixtures and 




                                      -12-
<PAGE>   13

         articles of personal property at least equal in quality and condition
         to those replaced, free from any security interest in or encumbrance
         thereon or reservation of title thereto other than liens permitted by
         the Credit Agreement and the Permitted Exceptions; provided, however,
         that Mortgagor may alter, remove or demolish any such building,
         improvement, fixture or appliance, and need not replace any such
         fixtures or personal property, in each case to the extent such action
         (i) is desirable to the proper conduct of the business of Mortgagor in
         the ordinary course as presently conducted and otherwise in the best
         interest of Mortgagor, (ii) does not impair the overall value or
         utility of the Mortgaged Premises and Mortgagor's other related
         properties as an integrated facility, (iii) does not decrease the
         efficiency or capacity of the Mortgaged Premises and (iv) does not
         impair the rights and benefits under this Mortgage of the Secured
         Creditors. Mortgagor further agrees to permit, commit or suffer no
         material waste, impairment or deterioration of the Mortgaged Premises
         or any part thereof; to keep and maintain said Mortgaged Premises and
         every part thereof in good working condition (ordinary wear and tear
         excepted); to effect such repairs as Mortgagee may reasonably require
         and from time to time to make all needful and proper replacements and
         additions so that said buildings, fixtures, machinery and appurtenances
         will, at all times, be in good working condition (ordinary wear and
         tear excepted), fit and proper for the respective purposes for which
         they were originally erected or installed; to comply with all statutes,
         orders, requirements or decrees relating to the Mortgaged Premises by
         any federal, state or municipal authority if the failure to comply with
         such statutes, orders, requirements or decrees could have a material
         adverse effect on the Mortgaged Premises or the business or financial
         condition of the Mortgagor; to observe and comply with all conditions
         and requirements necessary to preserve and extend any and all rights,
         licenses, permits (including, but not limited to, zoning variances,
         special exceptions and non-conforming uses), privileges, franchises and
         concessions which are applicable to the Mortgaged Premises or which
         have been granted to or contracted for by Mortgagor in connection with
         any existing or presently contemplated use of the Mortgaged Premises or
         any part thereof and not to initiate or acquiesce in any changes to or
         terminations of any of the foregoing or of zoning classifications
         affecting the use to which the Mortgaged Premises or any part thereof
         may be put without the prior written consent of Mortgagee; and to make
         no material alterations in or improvements or additions to the
         Mortgaged Premises except as required by governmental authority or as
         permitted by Mortgagee. Mortgagor will not lease the Mortgaged Premises
         or any material part thereof without the prior written consent of
         Mortgagee, which consent shall not be unreasonably withheld.

                   12. Liens and Encumbrances. Mortgagor will not, without the
         prior written consent of Mortgagee, directly or indirectly, create or
         suffer to be created or to remain and will discharge or promptly cause
         to be discharged any mortgage, lien, encumbrance or charge on, pledge
         of, or conditional sale or other title retention agreement with respect



                                      -13-

         to, the Mortgaged Premises or any part thereof, whether superior or
         subordinate to the lien hereof, except for this instrument, liens
         permitted by the Credit Agreement and the Permitted Exceptions.

                   13. Right of Mortgagee to Perform Mortgagor's Covenants, Etc.
         If Mortgagor shall fail to make any payment or perform any act required
         to be made or performed hereunder, Mortgagee, without waiving or
         releasing any obligation or default, may (but shall be under no
         obligation to) at any time after notice to the Mortgagor make such
         payment or perform such act for the account and at the expense of
         Mortgagor, and may enter upon the Mortgaged Premises or any part
         thereof for such purpose and take all such action thereon as, in the
         opinion of Mortgagee, may be reasonably necessary or appropriate
         therefor. All sums so paid by Mortgagee and all reasonable costs and
         expenses (including without limitation attorney's fees and expenses) so
         incurred, together with interest thereon from the date of payment or
         incurrence at the Default Rate, shall constitute so much additional
         indebtedness hereby secured and shall be paid by Mortgagor to Mortgagee
         on demand. Mortgagee in making any payment authorized under this
         Section relating to taxes or assessments may do so according to any
         bill, statement or estimate procured from the appropriate public office
         without inquiry into the accuracy of such bill, statement or estimate
         or into the validity of any tax assessment, sale, forfeiture, tax lien
         or title or claim thereof.

                   14. After-Acquired Property. Any and all property hereafter
         acquired which is of the kind or nature herein provided, or intended to
         be and become subject to the lien hereof, shall ipso facto, and without
         any further conveyance, assignment or act on the part of Mortgagor,
         become and be subject to the lien of this Mortgage as fully and
         completely as though specifically described herein; but nevertheless
         Mortgagor shall from time to time, if requested by Mortgagee, execute
         and deliver any and all such further assurances, conveyances and
         assignments as Mortgagee may reasonably require for the purpose of
         expressly and specifically subjecting to the lien of this Mortgage all
         such property.

                   15. Inspection by Mortgagee. Mortgagee, any Secured Creditor
         and their respective representatives shall have the right to inspect
         the Mortgaged Premises at all reasonable times, and access thereto
         shall be permitted for that purpose; provided, however, that prior to
         the occurrence of any Default or Event of Default hereunder, any such
         access or inspection shall only be required during the Mortgagor's
         normal business hours and shall only be permitted with at least 24
         hours advance notice.

                   16. Reports on Mortgaged Premises. Mortgagor will furnish to
         Mortgagee or any Secured Creditor such information and data with
         respect to the Mortgaged Premises as Mortgagee or such Secured Creditor
         may reasonably request.



                                      -14-
<PAGE>   15

                   17. Subrogation. Mortgagor acknowledges and agrees that
         Mortgagee shall be subrogated to any lien discharged out of the
         proceeds of the loan evidenced by any Note or out of any advance by
         Mortgagee hereunder, irrespective of whether or not any such lien may
         have been released of record.

                   18. Events of Default. Any one or more of the following shall
         constitute an event of default hereunder:

                            (a) Failure to pay when due any indebtedness hereby
                  secured; or

                            (b) Any event occurs or condition exists which is
                  specified as an Event of Default under the Credit Agreement;
                  or

                            (c) The Mortgaged Premises or any material part
                  thereof shall be sold, transferred, or conveyed, whether
                  voluntarily or involuntarily, by operation of law or
                  otherwise, except for sales of obsolete, worn out or unusable
                  fixtures or personal property which are concurrently replaced
                  (unless the Mortgagor, in the exercise of its commercially
                  reasonable judgment deems such replacement not necessary or
                  impractical and such failure to replace would cause no
                  material adverse change in the Mortgaged Premises) with
                  similar fixtures or personal property at least equal in
                  quality and condition to those sold and owned by Mortgagor
                  free of any lien, charge or encumbrance other than the lien
                  hereof; or

                            (d) Any indebtedness secured by a lien or charge on
                  the Mortgaged Premises or any part thereof is not paid when
                  due after the expiration of applicable grace periods and the
                  giving of applicable notices, if any (unless such indebtedness
                  is being contested in good faith by appropriate proceedings
                  which prevent the enforcement of the matter under contest and
                  adequate reserves have been established therefor), or
                  proceedings are commenced to foreclose or otherwise realize
                  upon any such lien or charge or to have a receiver appointed
                  for the property subject thereto or to place the holder of
                  such indebtedness or its representative in possession thereof;
                  or

                            (e)     The Mortgaged Premises is abandoned.

                   19. Remedies. When any event of default has happened and is
         continuing (regardless of the pendency of any proceeding which has or
         might have the effect of preventing Mortgagor from complying with the
         terms of this instrument and of the adequacy of the security for the
         Notes, Letters of Credit and the other indebtedness 




                                      -15-

         hereby secured) and in addition to such other rights as may be
         available under applicable law, but subject at all times to any
         mandatory legal requirements:

                            (a) Acceleration. As and to the extent expressly
                  permitted by the Credit Agreement, Mortgagee may, by written
                  notice to Mortgagor, declare the Notes and all unpaid
                  indebtedness hereby secured, including the reimbursement
                  obligations of the Mortgagor in connection with any Letters of
                  Credit, including any interest then accrued thereon, to be
                  forthwith due and payable, whereupon the same shall become and
                  be forthwith due and payable, without other notice or demand
                  of any kind.

                            (b) Uniform Commercial Code. Mortgagee shall, with
                  respect to any part of the Mortgaged Premises constituting
                  property of the type in respect of which realization on a lien
                  or security interest granted therein is governed by the
                  Uniform Commercial Code, have all the rights, options and
                  remedies of a secured party under the Uniform Commercial Code
                  of Illinois, including without limitation, the right to the
                  possession of any such property, or any part thereof, and the
                  right to enter without legal process any premises where any
                  such property may be found. Any requirement of said Code for
                  reasonable notification shall be met by mailing written notice
                  to Mortgagor at its address above set forth at least 10
                  Business Days prior to the sale or other event for which such
                  notice is required. The expenses of retaking, selling, and
                  otherwise disposing of said property, including reasonable
                  attorney's fees and legal expenses incurred in connection
                  therewith, shall constitute so much additional indebtedness
                  hereby secured and shall be payable upon demand with interest
                  at the Default Rate.

                            (c) Foreclosure. Mortgagee may proceed to protect
                  and enforce the rights of Mortgagee or Secured Creditors
                  hereunder (i) by any action at law, suit in equity or other
                  appropriate proceedings, whether for the specific performance
                  of any agreement contained herein, or for an injunction
                  against the violation of any of the terms hereof, or in aid of
                  the exercise of any power granted hereby or by law, or (ii) by
                  the foreclosure of this Mortgage. Without limiting anything to
                  the contrary contained herein, to the extent permitted by
                  applicable law, Mortgagee in Mortgagee's sole discretion, may
                  elect to foreclose this Mortgage by means of non-judicial
                  foreclosure as permitted by Chapter 655A of the Code of Iowa.
                  By its execution hereof, Mortgagor hereby agrees that if
                  Mortgagor's waiver of redemption rights in Section 20 hereof
                  shall have no force and effect and if the real estate
                  described in Granting Clause I hereof is ten acres or less in
                  size, then the period of redemption after sale on any
                  foreclosure of this Mortgage shall be reduced to six months,
                  provided the Mortgagee waives in such 



                                      -16-
<PAGE>   17

                  foreclosure action any rights to a deficiency judgment against
                  the Mortgagor which might arise out of such foreclosure
                  proceedings, all to be consistent with the provisions of
                  Chapter 628 of the Code of Iowa. It is further hereby agreed
                  that if Mortgagee's waiver of redemption rights in Section 20
                  hereof shall have no force and effect and if the real estate
                  described in Granting Clause I hereof is ten acres or more in
                  size, then the period of redemption after sale on any
                  foreclosure of this Mortgage shall be reduced to sixty days
                  provided (i) the court with jurisdiction over such a
                  foreclosure action finds affirmatively in a decree of
                  foreclosure that said real estate has been abandoned by the
                  owners and those persons personally liable under the Mortgage
                  at the time of such foreclosure, and (ii) the Mortgagee waives
                  any rights to a deficiency judgment against the Mortgagor or
                  his successors in interest in the foreclosure action, all to
                  be consisted with the provisions of Chapter 628 of the Code of
                  Iowa. Nothing contained herein shall obligate Mortgagee to so
                  waive its rights to such a deficiency judgment in either case,
                  and the decision to do so shall be solely at the discretion of
                  Mortgagee. By its execution hereof, Mortgagor further hereby
                  agrees that, notwithstanding anything to the contrary
                  contained herein, Mortgagee may, at Mortgagee's sole
                  discretion, elect to foreclose upon the Mortgaged Premises
                  without redemption pursuant to the provisions of Section
                  654.20 of the Code of Iowa and may elect, at Mortgagee's sole
                  discretion, to so foreclose with or without a waiver of its
                  rights to a deficiency judgment.

                            (d) Appointment of Receiver. Mortgagee shall, as a
                  matter of right, without notice and without giving bond to
                  Mortgagor or anyone claiming by, under or through it, and
                  without regard to the solvency or insolvency of Mortgagor or
                  the then value of the Mortgaged Premises, be entitled to have
                  a receiver appointed of all or any part of the Mortgaged
                  Premises and the rents, issues and profits thereof, with such
                  power as the court making such appointment shall confer, and
                  Mortgagor hereby consents to the appointment of such receiver
                  and shall not oppose any such appointment. Any such receiver
                  may, to the extent permitted under applicable law, without
                  notice, enter upon and take possession of the Mortgaged
                  Premises or any part thereof by force, summary proceedings,
                  ejectment or otherwise, and may remove Mortgagor or other
                  persons and any and all property therefrom, and may hold,
                  operate and manage the same and receive all earnings, income,
                  rents, issues and proceeds accruing with respect thereto or
                  any part thereof, whether during the pendency of any
                  foreclosure or until any right of redemption shall expire or
                  otherwise.

                            (e) Taking Possession, Collecting Rents, Etc.
                  Mortgagee may enter and take possession of the Mortgaged
                  Premises or any part thereof and manage, 



                                      -17-
<PAGE>   18

                  operate, insure, repair and improve the same and take any
                  action which, in Mortgagee's reasonable judgment, is necessary
                  or proper to conserve the value of the Mortgaged Premises.
                  Mortgagee may also take possession of, and for these purposes
                  use, any and all personal property contained in the Mortgaged
                  Premises and used in the operation, rental or leasing thereof
                  or any part thereof. Mortgagee shall be entitled to collect
                  and receive all earnings, revenues, rents, issues and profits
                  of the Mortgaged Premises or any part thereof (and for such
                  purpose Mortgagor does hereby irrevocably constitute and
                  appoint Mortgagee its true and lawful attorney-in-fact for it
                  and in its name, place and stead to receive, collect and
                  receipt for all of the foregoing, Mortgagor irrevocably
                  acknowledging that any payment made to Mortgagee hereunder
                  shall be a good receipt and acquittance against Mortgagor to
                  the extent so made) and to apply same to the reduction of the
                  indebtedness hereby secured. The right to enter and take
                  possession of the Mortgaged Premises and use any personal
                  property therein, to manage, operate and conserve the same,
                  and to collect the rents, issues and profits thereof, shall be
                  in addition to all other rights or remedies of Mortgagee
                  hereunder or afforded by law, and may be exercised
                  concurrently therewith or independently thereof. The
                  reasonable expenses (including any receiver's fees, counsel
                  fees, costs and agent's compensation) incurred pursuant to the
                  powers herein contained shall be so much additional
                  indebtedness hereby secured which Mortgagor promises to pay
                  upon demand together with interest at the Default Rate.
                  Mortgagee shall not be liable to account to Mortgagor for any
                  action taken pursuant hereto other than to account for any
                  rents actually received by Mortgagee. Without taking
                  possession of the Mortgaged Premises, Mortgagee may, in the
                  event the Mortgaged Premises becomes vacant or is abandoned,
                  take such steps as it deems appropriate to protect and secure
                  the Mortgaged Premises (including hiring watchmen therefor)
                  and all reasonable costs incurred in so doing shall constitute
                  so much additional indebtedness hereby secured payable upon
                  demand with interest thereon at the Default Rate.

                   20. Waiver of Right to Redeem From Sale - Waiver of
         Appraisement, Valuation, Etc. Mortgagor shall not and will not apply
         for or avail itself of any appraisement, valuation, stay, extension or
         exemption laws, or any so-called "Moratorium Laws", now existing or
         hereafter enacted in order to prevent or hinder the enforcement or
         foreclosure of this Mortgage, but hereby waives the benefit of such
         laws. Mortgagor for itself and all who may claim through or under it
         waives any and all right to have the property and estates comprising
         the Mortgaged Premises marshalled upon any foreclosure of the lien
         hereof and agrees that any court having jurisdiction to foreclose such
         lien may order the Mortgaged Premises sold as an entirety. In the event
         of any sale made under or by virtue of this instrument, the whole of
         the Mortgaged Premises may be 




                                      -18-
<PAGE>   19

         sold in one parcel as an entirety or in separate lots or parcels at the
         same or different times, all as the Mortgagee may determine. Mortgagee
         or any Secured Creditor shall have the right to become the purchaser at
         any sale made under or by virtue of this instrument; and Mortgagee or
         any Secured Creditor so purchasing at any such sale shall have the
         right to be credited upon the amount of the bid made therefor by
         Mortgagee or such Secured Creditor with the amount payable to Mortgagee
         or such Secured Creditor, as the case may be, out of the net proceeds
         of such sale, and upon compliance with the terms of sale, may hold,
         retain and possess and dispose of such property in its own absolute
         right without further accountability. In the event of any such sale,
         the Notes, the Reimbursement Obligations and the other indebtedness
         hereby secured, if not previously due, shall be and become immediately
         due and payable without demand or notice of any kind. Mortgagor hereby
         waives any and all rights of redemption prior to or from sale under any
         order or decree of foreclosure pursuant to rights herein granted, on
         behalf of Mortgagor, and each and every person acquiring any interest
         in, or title to the Mortgaged Premises described herein subsequent to
         the date of this Mortgage, and on behalf of all other persons to the
         extent permitted by applicable law.

                   21. Costs and Expenses of Foreclosure. In any suit to
         foreclose the lien hereof there shall be allowed and included as
         additional indebtedness in the decree for sale all reasonable
         expenditures and expenses which may be paid or incurred by or on behalf
         of Mortgagee or any Secured Creditor for attorney's fees, appraiser's
         fees, outlays for documentary and expert evidence, stenographic
         charges, publication costs and costs (which may be estimated as to
         items to be expended after the entry of the decree) of procuring all
         such abstracts of title, title searches and examination, guarantee
         policies, Torrens certificates and similar data and assurances with
         respect to title as Mortgagee or any Secured Creditor may deem to be
         reasonably necessary either to prosecute any foreclosure action or to
         evidence to the bidder at any sale pursuant thereto the true condition
         of the title to or the value of the Mortgaged Premises, all of which
         expenditures shall become so much additional indebtedness hereby
         secured which Mortgagor agrees to pay and all of such shall be
         immediately due and payable with interest thereon from the date of
         expenditure until paid at the Default Rate.

                   22. Application of Proceeds. The proceeds and avails of the
         Mortgaged Premises, including without limitation the proceeds of any
         foreclosure sale of the Mortgaged Premises or of any sale of property
         pursuant to Section l9(b) hereof, shall, when received by Mortgagee in
         cash or its equivalent, be applied by the Mortgagee as set forth in
         Section 3.5 of the Credit Agreement. Mortgagor shall remain liable to
         Mortgagee and the Secured Creditors for any deficiency. Any surplus
         remaining after the full payment and satisfaction of the foregoing
         shall be returned to Mortgagor or to whomsoever a court of competent
         jurisdiction shall determine to be entitled thereto.

<PAGE>   20

                   23. Deficiency Decree. If at any foreclosure proceeding the
         Mortgaged Premises shall be sold for a sum less than the total amount
         of indebtedness for which judgment is therein given, the judgment
         creditor shall be entitled to the entry of a deficiency decree against
         Mortgagor and against the property of Mortgagor for the amount of such
         deficiency; and Mortgagor does hereby irrevocably consent to the
         appointment of a receiver for the Mortgaged Premises and the property
         of Mortgagor and of the rents, issues and profits thereof after such
         sale and until such deficiency decree is satisfied in full.

                   24. Mortgagee's Remedies Cumulative - No Waiver. No remedy or
         right of Mortgagee shall be exclusive of but shall be cumulative and in
         addition to every other remedy or right now or hereafter existing at
         law or in equity or by statute or otherwise. No delay in the exercise
         or omission to exercise any remedy or right accruing on any default
         shall impair any such remedy or right or be construed to be a waiver of
         any such default or acquiescence therein, nor shall it affect any
         subsequent default of the same or a different nature. Every such remedy
         or right may be exercised concurrently or independently, and when and
         as often as may be deemed expedient by Mortgagee.

                   25. Mortgagee Party to Suits. Mortgagee shall have the power
         and authority (but not the duty) to institute and maintain any suits
         and proceedings as Mortgagee may deem advisable (a) to prevent any
         impairment of the Mortgaged Premises by any acts which may be unlawful
         or which violate the terms of this Mortgage, (b) to preserve or protect
         its interest in the Mortgaged Premises or (c) to restrain the
         enforcement of or compliance with any legislation or other governmental
         enactment, rule or order that may be unconstitutional or otherwise
         invalid, if the enforcement of or compliance with such enactment, rule
         or order might impair the security hereunder or be prejudicial to
         Mortgagee's or Secured Creditor's interest. If Mortgagee or any Secured
         Creditor shall be made a party to or shall intervene in any action or
         proceeding affecting the Mortgaged Premises or the title thereto or the
         interest of Mortgagee or any Secured Creditor under this Mortgage
         (including probate and bankruptcy proceedings), or if Mortgagee or any
         Secured Creditor employs an attorney to collect any or all of the
         indebtedness hereby secured or to enforce any of the terms hereof or
         realize hereupon or to protect the lien hereof, or if Mortgagee or any
         Secured Creditor shall incur any costs or expenses in preparation for
         the commencement of any foreclosure proceedings or for the defense of
         any threatened suit or proceeding which might affect the Mortgaged
         Premises or the security hereof, whether or not any such foreclosure or
         other suit or proceeding shall be actually commenced, then in any such
         case, Mortgagor agrees to pay to Mortgagee or such Secured Creditor, as
         the case may be, immediately and without demand, all reasonable costs,
         charges, expenses and attorney's fees incurred by Mortgagee or such


                                      -20-

<PAGE>   21

         Secured Creditor in any such case, and the same shall constitute so
         much additional indebtedness hereby secured payable upon demand with
         interest at the Default Rate.

                   26. Modifications Not to Affect Lien. Mortgagee, without
         notice to anyone (except the Secured Lenders), and without regard to
         the consideration, if any, paid therefor, or the presence of other
         liens on the Mortgaged Premises, may at the direction of the Secured
         Lenders release any part of the Mortgaged Premises or any person liable
         for any of the indebtedness hereby secured, may extend the time of
         payment of any of the indebtedness hereby secured and may grant waivers
         or other indulgences with respect hereto and thereto, and may agree
         with Mortgagor to modifications to the terms and conditions contained
         herein or otherwise applicable to any of the indebtedness hereby
         secured (including modifications in the rates of interest applicable
         thereto), without in any way affecting or impairing the liability of
         any party liable upon any of the indebtedness hereby secured or the
         priority of the lien of this Mortgage upon all of the Mortgaged
         Premises not expressly released, and any party acquiring any direct or
         indirect interest in the Mortgaged Premises shall take same subject to
         all of the provisions hereof.

                   27. Revolving Credit Loan. This Mortgage is given to secure,
         among other things, a revolving credit loan and shall secure not only
         presently existing indebtedness under the Credit Agreement but also
         future advances, or otherwise, as are made within twenty (20) years
         from the date hereof, to the same extent as if such future advances
         were made on the date of the execution of this Mortgage, although there
         may be no advance made at the time of execution of this Mortgage and
         although there may be no indebtedness hereby secured outstanding at the
         time any advance is made. The lien of this Mortgage shall be valid as
         to all indebtedness hereby secured, including future advances, from the
         time of its filing for record in the recorder's or registrar's office
         of the county in which the Mortgaged Premises are located. The total
         amount of indebtedness hereby secured may increase or decrease from
         time to time, but the total unpaid balance of indebtedness hereby
         secured (including disbursements which Mortgagee may make under this
         Mortgage, the Credit Agreement or any other documents related thereto)
         at any one time outstanding shall not exceed a maximum principal amount
         of One Hundred Million Dollars ($100,000,000) plus interest thereon and
         any disbursements made for payment of taxes, special assessments or
         insurance on the Mortgaged Premises and interest on such disbursements
         (all such indebtedness being hereinafter referred to as the "maximum
         amount secured hereby"). This Mortgage shall be valid and have priority
         over all subsequent liens and encumbrances, including statutory liens,
         excepting solely taxes and assessments levied on the Mortgaged
         Premises, to the extent of the maximum amount secured hereby.

         writing to the Mortgagee, the Mortgaged Premises, including all
         personal property, is free from contamination, that there has not been

                   32. Use of Property and Facilities. Mortgagor represents and
         warrants that to the best of its knowledge, except as heretofore
         disclosed in writing to the Mortgagee, it has never in the past engaged

         operations or activity on the Mortgaged Premises, or employ or use the
         personal property or facilities, to manufacture, use, generate, treat,
         store, transport or dispose of any hazardous substance (including,
         without limitation, petroleum, its derivatives or by-products, or other

         or regulated under applicable law, or which poses a threat or nuisance
         to safety, health or the environment, including, without limitation,

         Amendments of 1984, 42 U.S.C. SS.6901 et seq., the Comprehensive

         limitation, any state statute providing for financial responsibility
         for cleanup for the release or threatened release of substances
         provided for thereunder. The provisions of this Section shall apply to
         all real and personal property, without limitation, owned or controlled
         by Mortgagor or its subsidiaries.

                   33. Partial Invalidity. All rights, powers and remedies
         provided herein are intended to be limited to the extent necessary so
         that they will not render this Mortgage invalid, unenforceable or not
         entitled to be recorded, registered or filed under any applicable law.
         If any term of this Mortgage shall be held to be invalid, illegal or



                                      -24-
<PAGE>   25

         unenforceable, the validity and enforceability of the other terms of
         this Mortgage shall in no way be affected thereby.

                   34. Agent. Mortgagee has been appointed as agent pursuant to
         the Credit Agreement. In acting under or by virtue of this Mortgage,
         Mortgagee shall be entitled to all the rights, authority, privileges
         and immunities provided in Section 10 of the Credit Agreement, all of
         which provisions of said Section 10 are incorporated by reference
         herein with the same force and effect as if set forth herein. Mortgagee
         hereby disclaims any representation or warranty to Secured Creditors
         concerning the perfection of the security interest granted hereunder or
         the value of the Mortgaged Premises.

                   35. Restrictions on Secured Creditors' Right to Enforce. No
         Secured Creditor shall have the right to institute any suit, action or
         proceeding in equity or at law for the foreclosure of this Mortgage or
         for the execution of any trust or power hereof or for the appointment
         of a receiver, or for the enforcement of any other remedy under or upon
         this Mortgage; it being understood and intended that no one or more of
         the Secured Creditors shall have any right in any manner whatsoever to
         affect, disturb or prejudice the lien of this Mortgage by its or their
         action or to enforce any right hereunder, and that all proceedings at
         law or in equity shall be instituted, had and maintained by the
         Mortgagee in the manner herein provided and for the ratable benefit of
         the Secured Creditors.

                   36. Successors and Assigns. Whenever any of the parties
         hereto is referred to, such reference shall be deemed to include the
         successors and assigns of such party; and all the covenants, promises
         and agreements in this Mortgage contained by or on behalf of Mortgagor,
         or by or on behalf of Mortgagee or Secured Creditors, shall bind and
         inure to the benefit of the respective successors and assigns of such
         parties, whether so expressed or not. Without limiting the generality
         of the foregoing, and subject to the provisions of Sections 12.14 and
         12.15 of the Credit Agreement, any Secured Creditor may assign or
         otherwise transfer any indebtedness held by it secured by this Mortgage
         to any other person or entity, and such other person or entity shall
         thereupon become vested with all the benefits in respect thereof
         granted to such Secured Creditor herein or otherwise, subject, however,
         to the provisions of the Credit Agreement.

                   37. Default Rate. For purposes of this Mortgage, "Default
         Rate" shall mean the rate per annum as set forth in Section 2.1 of the
         Credit Agreement.

                   38. Liens Absolute, Etc. Mortgagor acknowledges and agrees
         that the lien and security interest hereby created and provided for are
         absolute and unconditional and shall not in any manner be affected or
         impaired by any acts or omissions whatsoever of Mortgagee or any other
         holder of any of the indebtedness hereby secured, and without 



                                      -25-
<PAGE>   26

         limiting the generality of the foregoing, the lien and security hereof
         shall not be impaired by any acceptance by Mortgagee or any other
         holder of any of the indebtedness hereby secured of any other security
         for or guarantors upon any of the indebtedness hereby secured or by any
         failure, neglect or omission on the part of Mortgagee or any other
         holder of any of the indebtedness hereby secured to realize upon or
         protect any of the indebtedness hereby secured or any collateral or
         security therefor. The lien and security interest hereof shall not in
         any manner be impaired or affected by (and Mortgagee, without notice to
         anyone, is hereby authorized to make from time to time) any sale,
         pledge, surrender, compromise, settlement, release, renewal, extension,
         indulgence, alteration, substitution, exchange, change in, modification
         or disposition of any of the indebtedness hereby secured, or of any
         collateral or security therefor, or of any guaranty thereof, or of any
         instrument or agreement setting forth the terms and conditions
         pertaining to any of the foregoing. The Secured Creditors may at their

         the Other Mortgages shall not in any manner impair the indebtedness
         hereby secured or the lien of this Mortgage and any exercise of the
         rights or remedies of Mortgagee hereunder shall not impair the lien of
         any of the Other Mortgages or any of Mortgagee's rights and remedies
         thereunder. The undersigned specifically consents and agrees that
         Mortgagee may exercise its rights and remedies hereunder and under the
