ITEM 2  -  ACQUISITION OF ASSETS

On July 7, 1998, Dexter Corporation ("Dexter") announced its intention to
acquire the remaining 48% equity in Life Technologies, Inc. ("LTI") that it did
not currently own. Dexter made a proposal to the LTI Board of Directors to
acquire the approximately 11.3 million shares of LTI common stock it did not own
at a price of $37 per share. The offer was to be financed through Dexter's
available cash and a committed credit facility arranged by First Chicago Capital
Markets, Inc. The offer was subject to the approval of LTI's Board of Directors.

On October 27, 1998, a special committee of independent directors of the LTI
Board that had been considering Dexter's proposal advised Dexter that it would
not recommend approval of its offer.

On November 2, 1998, Dexter commenced a tender offer, for $37 per share in cash,
for all outstanding shares of common stock of LTI that it did not currently own.
Consummation of the tender offer was conditioned upon Dexter receiving
sufficient shares to own at least 80 percent of all outstanding LTI shares on a
fully diluted basis. The offer was scheduled to expire on December 1, 1998. As
of December 1, 1998, approximately 2.3 million shares of LTI common stock had
been tendered and not withdrawn. On December 2, 1998, Dexter extended the tender
offer until December 4, 1998 with all other terms of the offer remaining the
same.

On December 7, 1998, Dexter revised its offer to acquire all the shares of LTI
that it did not own to increase the offer price to $39.125 per share in cash,
eliminate the minimum share condition to the original tender offer, and extend 
the expiration of the tender offer to December 22, 1998.

On December 22, 1998, Dexter completed its tender offer. Approximately 5.5
million shares of LTI common stock had been tendered and not withdrawn,
representing approximately 22% of all issued and outstanding LTI shares. The
total cost of the 5.5 million shares tendered was approximately $216 million
which was financed through a $300 million credit agreement among Dexter
Corporation, The First National Bank of Chicago, Bank of America National Trust
and Savings Association, Fleet National Bank, and the Lenders named therein,
dated December 15, 1998. As a result of the acquisition of these shares, Dexter
owns an aggregate of approximately 17.8 million shares or approximately 71% of
the total number of issued and outstanding shares.

part of the Agent or any Lender, (i) each Eurodollar Advance shall bear interest
for the remainder of the applicable Interest Period at the rate otherwise
applicable to such Interest Period plus 2% per annum and (ii) each Alternate
Base Rate Advance shall bear interest at a rate per annum equal to the Alternate
Base Rate in effect from time to time plus 2% per annum and (iii) the fee
payable pursuant to Section 2.19.6(b) with respect to all outstanding Facility
Letters of Credit shall be increased by 2% per annum.

         2.12. Method of Payment. All payments of the Obligations hereunder
shall be made, without setoff, deduction, or counterclaim, in immediately
available funds to the Agent at the Agent's address specified pursuant to
Article XIII, or at any other Lending Installation of the Agent specified in
writing by the Agent to the Borrower, by noon (Chicago time) on the date when
due and shall be applied ratably by the Agent among the Lenders. Each payment
delivered to the Agent for the account of any Lender shall be delivered promptly
by the Agent to such Lender in the same type of funds that the Agent received at
its address specified pursuant to Article XIII or at any Lending Installation
specified in a notice received by the Agent from such Lender. The Agent is
hereby authorized to charge the account of the Borrower maintained with First
Chicago for each payment of principal, interest and fees as it becomes due
hereunder.

         2.13. Noteless Agreement; Evidence of Indebtedness. (a) Each Lender
shall maintain in accordance with its usual practice an account or accounts
evidencing the indebtedness of the Borrower to such Lender resulting from each
Loan made by such Lender from time to time, including the amounts of principal
and interest payable and paid to such Lender from time to time hereunder.

                    (b) The Agent shall also maintain accounts in which it will
record (i) the amount of each Loan made hereunder, the Type thereof and the
Interest Period with respect thereto, (ii) the amount of any principal or
interest due and payable or to become due and payable from the Borrower to each
Lender hereunder and (iii) the amount of any sum received by the Agent hereunder
from the Borrower and each Lender's share thereof.

                    (c) The entries maintained in the accounts maintained
pursuant to paragraphs (a) and (b) above shall be prima facie evidence of the
existence and amounts of the Obligations therein recorded; provided, however,
that in the event of a conflict between the accounts maintained pursuant to
paragraphs (a) and (b) above, the accounts maintained pursuant to paragraph (a)
above shall be presumed to be correct absent demonstrable error, provided,
further, that the failure of the Agent or any Lender to maintain such accounts
or any error therein shall not in any manner affect the obligation of the
Borrower to repay the Obligations in accordance with their terms.

                    (d) Any Lender may request that its Loans be evidenced by a
promissory note (a "Note"). In such event, the Borrower shall prepare, execute
and deliver to such Lender a Note payable to the order of such Lender in a form
supplied by the Agent. Thereafter, the Loans evidenced by such Note and interest
thereon shall at all times (including after any assignment pursuant to Section
12.3) be represented by one or more Notes payable to the order of the payee
named therein or any assignee pursuant to Section 12.3, except to the extent
that any such Lender or assignee subsequently returns any such Note for
cancellation and requests that such Loans once again be evidenced as described
in paragraphs (a) and (b) above.

         2.14. Telephonic Notices. The Borrower hereby authorizes the Lenders
and the Agent to extend, convert or continue Advances, effect selections of
Types of Advances and to transfer funds based on telephonic notices made by any
person or persons the Agent or any Lender in good faith believes to be an
Authorized Officer or other person previously authorized in writing by the
Borrower to take such actions on behalf of the Borrower. The Borrower agrees to
deliver promptly to the Agent a written confirmation, if such confirmation is
requested by the Agent or any Lender, of each telephonic notice signed by an
Authorized Officer. If the written confirmation differs in any material respect
from the action taken by the Agent and the Lenders, the records of the Agent and
the Lenders shall govern absent manifest error.

         2.15. Interest Payment Dates; Interest and Fee Basis. Interest accrued
on each Alternate Base Rate Advance shall be payable on each Payment Date,
commencing with the first such date to occur after the date hereof and at
maturity. Interest accrued on each Eurodollar Advance shall be payable on the
last day of its applicable Interest Period, on any date on which the Eurodollar
Advance is prepaid, whether by acceleration or otherwise, and at maturity.
Interest accrued on each Eurodollar Advance having an Interest Period longer
than three months shall also be payable on the


                                      -19-
<PAGE>   27

last day of each three-month interval during such Interest Period. Interest
shall be calculated for actual days elapsed on the basis of a 365 (or 366, as
applicable) day year with respect to Alternate Base Rate Advances. Interest with
respect to Eurodollar Advances and fees shall be calculated for actual days
elapsed on the basis of a 360-day year. Interest shall be payable for the day an
Advance is made but not for the day of any payment on the amount paid if payment
is received prior to noon (Chicago time) at the place of payment. If any payment
of principal of or interest on an Advance shall become due on a day which is not
a Business Day, such payment shall be made on the next succeeding Business Day
and, in the case of a principal payment, such extension of time shall be
included in computing interest in connection with such payment.

         2.16. Notification of Advances, Interest Rates, Prepayments, Commitment
Reductions and Issuance Requests. Promptly after receipt thereof, the Agent will
notify each Lender of the contents of each Aggregate Commitment reduction
notice, Borrowing Notice, Conversion/ Continuation Notice, Issuance Request and
repayment notice received by it hereunder. The Agent will notify each Lender of
the interest rate applicable to each Eurodollar Advance promptly upon
determination of such interest rate and will give each Lender prompt notice of
each change in the Alternate Base Rate.

         2.17. Lending Installations. Each Lender may book its Loans at any
Lending Installation selected by such Lender and may change its Lending
Installation from time to time. All terms of this Agreement shall apply to any
such Lending Installation and the Loans and any Notes issued hereunder shall be
deemed held by each Lender for the benefit of such Lending Installation. Each
Lender may, by written notice to the Agent and the Borrower in accordance with
Article XIII, designate replacement or additional Lending Installations through
which Loans will be made by it and for whose account Loan payments are to be
made.

         2.18. Non-Receipt of Funds by the Agent. Unless the Borrower or a
Lender, as the case may be, notifies the Agent prior to the date on which it is
scheduled to make payment to the Agent of (a) in the case of a Lender, the
proceeds of a Loan or (b) in the case of the Borrower, a payment of principal,
interest or fees to the Agent for the account of the Lenders, that it does not
intend to make such payment, the Agent may assume that such payment has been
made. The Agent may, but shall not be obligated to, make the amount of such
payment available to the intended recipient in reliance upon such assumption. If
such Lender or the Borrower, as the case may be, has not in fact made such
payment to the Agent, the recipient of such payment shall, on demand by the
Agent, repay to the Agent the amount so made available together with interest
thereon in respect of each day during the period commencing on the date such
amount was so made available by the Agent until the date the Agent recovers such
amount at a rate per annum equal to (x) in the case of payment by a Lender, the
Federal Funds Effective Rate for such day or (y) in the case of payment by the
Borrower, the interest rate applicable to the relevant Loan.

         2.19. Facility Letters of Credit.

                  2.19.1 Issuance of Facility Letters of Credit. (a) From and
         after the date hereof, the Issuer agrees, upon the terms and conditions
         set forth in this Agreement, to issue at the request and for the
         account of the Borrower, one or more Facility Letters of Credit;


                                      -20-
<PAGE>   28

         provided, however, that the Issuer shall not be under any obligation to
         issue, and shall not issue, any Facility Letter of Credit if (i) any
         order, judgment or decree of any governmental authority or other
         regulatory body with jurisdiction over the Issuer shall purport by its
         terms to enjoin or restrain such Issuer from issuing such Facility
         Letter of Credit, or any law or governmental rule, regulation, policy,
         guideline or directive (whether or not having the force of law) from
         any governmental authority or other regulatory body with jurisdiction
         over the Issuer shall prohibit, or request that the Issuer refrain
         from, the issuance of Facility Letters of Credit in particular or shall
         impose upon the Issuer with respect to any Facility Letter of Credit
         any restriction or reserve or capital requirement (for which the Issuer
         is not otherwise compensated) or any unreimbursed loss, cost or expense
         which was not applicable, in effect and known to the Issuer as of the
         date of this Agreement and which the Issuer in good faith deems
         material to it; (ii) one or more of the conditions to such issuance
         contained in Section 4.2 is not then satisfied; or (iii) after giving
         effect to such issuance, the aggregate outstanding amount of the
         Facility Letter of Credit Obligations would exceed the Facility Letter
         of Credit Sublimit.

                  (b) In no event shall: (i) the aggregate amount of the
         Facility Letter of Credit Obligations at any time exceed the Facility
         Letter of Credit Sublimit; (ii) the sum at any time of (A) the
         aggregate amount of Facility Letter of Credit Obligations and (B) the
         aggregate principal balance of outstanding Advances exceed the amount
         of the Aggregate Commitment; or (iii) the expiration date of any
         Facility Letter of Credit (including, without limitation, Facility
         Letters of Credit issued with an automatic "evergreen" provision
         providing for renewal absent advance notice by the Borrower or the
         Issuer), or the date for payment of any draft presented thereunder and
         accepted by the Issuer, be later than the earlier of (A) one year after
         the date of issuance and (B) five (5) Business Days prior to the
         Facility Termination Date.

                  2.19.2 Participating Interests. Immediately upon the issuance
         by the Issuer of a Facility Letter of Credit in accordance with Section
         2.19.4, each Lender shall be deemed to have irrevocably and
         unconditionally purchased and received from the Issuer, without
         recourse, representation or warranty, an undivided participation
         interest equal to its pro-rata share of the Aggregate Commitment of the
         face amount of such Facility Letter of Credit and each draw paid by the
         Issuer thereunder. Each Lender's obligation to pay its proportionate
         share of all draws under the Facility Letters of Credit, absent gross
         negligence or willful misconduct by the Issuer in honoring any such
         draw, shall be absolute, unconditional and irrevocable and in each case
         shall be made without counterclaim or set-off by such Lender.

                  2.19.3 Facility Letter of Credit Reimbursement Obligations.
         (a) The Borrower agrees to pay to the Issuer of a Facility Letter of
         Credit (i) on each date that any amount is drawn under each Facility
         Letter of Credit a sum (and interest on such sum as provided in clause
         (ii) below) equal to the amount so drawn plus all other charges and
         expenses with respect thereto specified in Section 2.19.6 or in the
         applicable Reimbursement Agreement and (ii) interest on any and all
         amounts remaining unpaid under this Section 2.19.3 until payment in
         full at the Alternate Base Rate plus the margin specified in Section
         2.11. The Borrower agrees to pay to the Issuer the amount of all
         Facility Letter of Credit


                                      -21-
<PAGE>   29

         Reimbursement Obligations owing in respect of any Facility Letter of
         Credit immediately when due, under all circumstances, including,
         without limitation, any of the following circumstances: (w) any lack of
         validity or enforceability of this Agreement or any of the other Loan
         Documents; (x) the existence of any claim, set-off, defense or other
         right which the Borrower may have at any time against a beneficiary
         named in a Facility Letter of Credit, any transferee of any Facility
         Letter of Credit (or any Person for whom any such transferee may be
         acting), any Lender or any other Person, whether in connection with
         this Agreement, any Facility Letter of Credit, the transactions
         contemplated herein or any unrelated transactions (including any
         underlying transaction between the Borrower and the beneficiary named
         in any Facility Letter of Credit); (y) the validity, sufficiency or
         genuineness of any document which the Issuer has determined in good
         faith and in the absence of gross negligence complies on its face with
         the terms of the applicable Facility Letter of Credit, even if such
         document should later prove to have been forged, fraudulent, invalid or
         insufficient in any respect or any statement therein shall have been
         untrue or inaccurate in any respect; or (z) the surrender or impairment
         of any security for the performance or observance of any of the terms
         hereof.

                  (b) Notwithstanding any provisions to the contrary in any
         Reimbursement Agreement, the Borrower agrees to reimburse the Issuer
         for amounts which the Issuer pays under such Facility Letter of Credit
         no later than the time specified in this Agreement. If the Borrower
         does not pay any such Facility Letter of Credit Reimbursement
         Obligations when due, the Borrower shall be deemed to have immediately
         requested that the Lenders make an Alternate Base Rate Advance under
         this Agreement in a principal amount equal to such unreimbursed
         Facility Letter of Credit Reimbursement Obligations. The Agent shall
         promptly notify the Lenders of such deemed request and, without the
         necessity of compliance with the requirements of Sections 2.5 and 4.2,
         each Lender shall make available to the Agent its Loan in the manner
         prescribed for Alternate Base Rate Advances. The proceeds of such Loans
         shall be paid over by the Agent to the Issuer for the account of the
         Borrower in satisfaction of such unreimbursed Facility Letter of Credit
         Reimbursement Obligations, which shall thereupon be deemed satisfied by
         the proceeds of, and replaced by, such Alternate Base Rate Advance.

                  (c) If the Issuer makes a payment on account of any Facility
         Letter of Credit and is not concurrently reimbursed therefor by the
         Borrower and if for any reason an Alternate Base Rate Advance may not
         be made pursuant to paragraph (b) above, then as promptly as practical
         during normal banking hours on the date of its receipt of such notice
         or, if not practicable on such date, not later than noon (Chicago time)
         on the Business Day immediately succeeding such date of notification,
         each Lender shall deliver to the Agent for the account of the Issuer,
         in immediately available funds, the purchase price for such Lender's
         interest in such unreimbursed Facility Letter of Credit Obligations,
         which shall be an amount equal to such Lender's pro-rata share of such
         payment. Each Lender shall, upon demand by the Issuer, pay the Issuer
         interest on such Lender's pro-rata share of such draw from the date of
         payment by the Issuer on account of such Facility Letter of Credit
         until the date of delivery of such funds to the Issuer by such Lender
         at a rate per annum, computed for actual days elapsed based on a
         360-day year, equal to the Federal Funds Effective Rate


                                      -22-
<PAGE>   30

         for such period; provided, that such payments shall be made by the
         Lenders only in the event and to the extent that the Issuer is not
         reimbursed in full by the Borrower for interest on the amount of any
         draw on the Facility Letters of Credit.

                  (d) At any time after the Issuer has made a payment on account
         of any Facility Letter of Credit and has received from any other Lender
         such Lender's pro-rata share of such payment, such Issuer shall,
         forthwith upon its receipt of any reimbursement (in whole or in part)
         by the Borrower for such payment, or of any other amount from the
         Borrower or any other Person in respect of such payment (including,
         without limitation, any payment of interest or penalty fees and any
         payment under any collateral account agreement of the Borrower or any
         Loan Document but excluding any transfer of funds from any other Lender
         pursuant to Section 2.19.3(b)), transfer to such other Lender such
         other Lender's ratable share of such reimbursement or other amount;
         provided, that interest shall accrue for the benefit of such Lender
         from the time such Issuer has made a payment on account of any Facility
         Letter of Credit; provided, further, that in the event that the receipt
         by the Issuer of such reimbursement or other amount is found to have
         been a transfer in fraud of creditors or a preferential payment under
         the United States Bankruptcy Code or is otherwise required to be
         returned, such Lender shall promptly return to the Issuer any portion
         thereof previously transferred by the Issuer to such Lender, but
         without interest to the extent that interest is not payable by the
         Issuer in connection therewith.

                  2.19.4 Procedure for Issuance. Prior to the issuance of each
         Facility Letter of Credit, and as a condition of such issuance, the
         Borrower shall deliver to the Issuer (with a copy to the Agent) a
         Reimbursement Agreement signed by the Borrower, together with such
         other documents or items as may be required pursuant to the terms
         thereof, and the proposed form and content of such Facility Letter of
         Credit shall be reasonably satisfactory to the Issuer. Each Facility
         Letter of Credit shall be issued no earlier than two (2) Business Days
         after delivery of the foregoing documents, which delivery may be by the
         Borrower to the Issuer by telecopy, telex or other electronic means
         followed by delivery of executed originals within five (5) days
         thereafter. The documents so delivered shall be in compliance with the
         requirements set forth in Section 2.19.1(b), and shall specify therein
         (i) the stated amount of the Facility Letter of Credit requested, (ii)
         the effective date of issuance of such requested Facility Letter of
         Credit, which shall be a Business Day, (iii) the date on which such
         requested Facility Letter of Credit is to expire, which shall be at
         least five (5) Business Days prior to the Facility Termination Date,
         (iv) the entity for which the requested Facility Letter of Credit is to
         be issued, which shall be the Borrower or a Subsidiary, and (v) the
         aggregate amount of Facility Letter of Credit Obligations which are
         outstanding and which will be outstanding after giving effect to the
         requested Facility Letter of Credit issuance. The delivery of the
         foregoing documents and information shall constitute an "Issuance
         Request" for purposes of this Agreement. Subject to the terms and
         conditions of Section 2.19.1 and provided that the applicable
         conditions set forth in Section 4.2 hereof have been satisfied, the
         Issuer shall, on the requested date, issue a Facility Letter of Credit
         on behalf of the Borrower in accordance with the Issuer's usual and
         customary business practices. In addition, any amendment of an existing
         Facility Letter of Credit shall be deemed to be an issuance of a new
         Facility Letter of Credit and shall be subject to the requirements set
         forth


                                      -23-
<PAGE>   31

         above. The Issuer shall give the Agent prompt written notice of the
         issuance of any Facility Letter of Credit.

                  2.19.5 Nature of the Lenders' Obligations. (a) As between the
         Borrower and the Lenders, the Borrower assumes all risks of the acts
         and omissions of, or misuse of the Facility Letters of Credit by, the
         respective beneficiaries of the Facility Letters of Credit. In
         furtherance and not in limitation of the foregoing, the Lenders shall
         not be responsible for (i) the form, validity, sufficiency, accuracy,
         genuineness or legal effect of any document submitted by any party in
         connection with the application for an issuance of a Facility Letter of
         Credit, even if it should in fact prove to be in any or all respects
         invalid, insufficient, inaccurate, fraudulent or forged; (ii) the
         validity or sufficiency of any instrument transferring or assigning or
         purporting to transfer or assign a Facility Letter of Credit or the
         rights or benefits thereunder or proceeds thereof, in whole or in part,
         which may prove to be invalid or ineffective for any reason; (iii) the
         failure of the beneficiary of a Facility Letter of Credit to comply
         fully with conditions required to be satisfied by any Person other than
         the Issuer in order to draw upon such Facility Letter of Credit; (iv)
         errors, omissions, interruptions or delays in transmission or delivery
         of any messages, by mail, cable, telegraph, telex or otherwise; (v)
         errors in the interpretation of technical terms; (vi) the
         misapplication by the beneficiary of a Facility Letter of Credit of the
         proceeds of any drawing under such Facility Letter of Credit; or (vii)
         any consequences arising from causes beyond control of the Issuer.

                  (b) In furtherance and extension and not in limitation of the
         specific provisions hereinabove set forth, any action taken or omitted
         by the Issuer under or in connection with the Facility Letters of
         Credit or any related certificates, if taken or omitted in good faith
         and in the absence of gross negligence, shall not put the Agent or any
         Lender under any resulting liability to the Borrower or relieve the
         Borrower of any of its obligations hereunder to the Issuer or any such
         Person.

                  2.19.6 Facility Letter of Credit Fees. The Borrower hereby
         agrees to pay to the Agent, for the ratable account of the Lenders,
         letter of credit fees with respect to each Facility Letter of Credit
         from and including the date of issuance thereof until the date such
         Facility Letter of Credit is fully drawn, cancelled or expired, equal
         to the Applicable Margin multiplied by the aggregate amount from time
         to time available to be drawn on such Facility Letter of Credit,
         calculated with respect to actual days elapsed on the basis of a
         360-day year and payable quarterly in arrears on each Payment Date in
         each year and upon the expiration, cancellation or utilization in full
         of such Facility Letter of Credit. In addition to the foregoing, the
         Borrower agrees to pay the Issuer for its own account (a) a fronting
         fee equal to .125% per annum on the face amount of each Facility Letter
         of Credit issued by such Issuer, calculated with respect to actual days
         elapsed on the basis of a 360-day year and payable quarterly in arrears
         and (b) any other fees customarily charged by it in respect of Letters
         of Credit issued by it.

         2.20. Extension of Facility Termination Date. The Borrower may request
an extension of the Facility Termination Date by submitting a request for an
extension to the Agent (an "Extension Request") no more than sixty (60) days
prior to each anniversary of the date hereof. The


                                      -24-
<PAGE>   32

Extension Request must specify the new Facility Termination Date requested by
the Borrower and the date (which must be at least thirty (30) days after the
Extension Request is delivered to the Agent) as of which the Lenders must
respond to the Extension Request (the "Response Date"). The new Facility
Termination Date shall be the date one year after the Facility Termination Date
in effect at the time the Extension Request is received. Promptly upon receipt
of an Extension Request, the Agent shall notify each Lender of the contents
thereof and shall request each Lender to approve the Extension Request. Each
Lender, acting in its sole discretion, may approve or decline to approve such
Extension Request. Each Lender approving the Extension Request shall deliver its
written consent no later than the Response Date. If and only if the written
consent of each of the Lenders is received by the Agent prior to the then
effective Facility Termination Date, the Facility Termination Date specified in
the Extension Request shall become effective on the existing Facility
Termination Date and the Agent shall promptly notify the Borrower and each
Lender of the new Facility Termination Date. Notwithstanding the foregoing, in
no event shall there be more than three one-year extensions pursuant to this

                                   ARTICLE III

                             YIELD PROTECTION; TAXES

         3.1. Yield Protection. If, on or after the date of this Agreement, the
adoption of any law or any governmental or quasi-governmental rule, regulation,
policy, guideline or directive (whether or not having the force of law), or any
change in the interpretation or administration thereof by any governmental or
quasi-governmental authority, central bank or comparable agency charged with the
interpretation or administration thereof, or compliance by any Lender or
applicable Lending Installation with any request or directive (whether or not
having the force of law) of any such authority, central bank or comparable
agency:

         (a)      subjects any Lender or any applicable Lending Installation to
                  any Taxes, or changes the basis of taxation of payments (other
                  than with respect to Excluded Taxes) to any Lender in respect
                  of its Eurodollar Loans or its interest in the Facility
                  Letters of Credit, or

         (b)      imposes or increases or deems applicable any reserve,
                  assessment, insurance charge, special deposit or similar
                  requirement against assets of, deposits with or for the
                  account of, or credit extended by, any Lender or any
                  applicable Lending Installation (other than reserves and
                  assessments taken into account in determining the interest
                  rate applicable to Eurodollar Advances), or

         (c)      imposes any other condition the result of which is to increase
                  the cost to any Lender or any applicable Lending Installation
                  of making, funding or maintaining its Eurodollar Loans or
                  issuing Facility Letters of Credit or reduces any amount
                  receivable by any Lender or any applicable Lending
                  Installation in connection with its Eurodollar Loans or any
                  Facility Letter of Credit, or requires any Lender or any


                                      -25-
<PAGE>   33

                  applicable Lending Installation to make any payment calculated
                  by reference to the amount of Eurodollar Loans held, Facility
                  Letters of Credit issued or participated in or interest
                  received by it, by an amount deemed material by such Lender,

and the result of any of the foregoing is to increase the cost to such Lender or
applicable Lending Installation of making or maintaining its Eurodollar Loans or
Commitment or its interest in the Facility Letters of Credit or to reduce the
return received by such Lender or applicable Lending Installation in connection
with such Eurodollar Loans or Commitment in either case by an amount which such
Lender deems to be material, then, within fifteen (15) days of demand by such
Lender, the Borrower shall pay such Lender such additional amount or amounts as
will compensate such Lender for such increased cost or reduction in amount
received.

         3.2. Changes in Capital Adequacy Regulations. If a Lender determines
the amount of capital required or expected to be maintained by such Lender, any
applicable Lending Installation of such Lender or any corporation controlling
such Lender is increased as a result of a Change, then, within fifteen (15) days
of demand by such Lender, the Borrower shall pay such Lender the amount
necessary to compensate for any shortfall in the rate of return on the portion
of such increased capital which such Lender determines is attributable to this
Agreement, its Loans or its Commitment to make Loans hereunder (after taking
into account such Lender's policies as to capital adequacy). "Change" means (i)
any change after the date of this Agreement in the Risk-Based Capital Guidelines
or (ii) any adoption of or change in any other law, governmental or
quasi-governmental rule, regulation, policy, guideline, interpretation, or
directive (whether or not having the force of law) after the date of this
Agreement which affects the amount of capital required or expected to be
maintained by any Lender or any Lending Installation or any corporation
controlling any Lender. "Risk-Based Capital Guidelines" means (i) the risk-based
capital guidelines in effect in the United States on the date of this Agreement,
including transition rules, and (ii) the corresponding capital regulations
promulgated by regulatory authorities outside the United States implementing the
July 1988 report of the Basle Committee on Banking Regulation and Supervisory
Practices Entitled "International Convergence of Capital Measurements and
Capital Standards," including transition rules, and any amendments to such
regulations adopted prior to the date of this Agreement.

         3.3. Availability of Types of Advances. If (a) any Lender determines
that maintenance of its Eurodollar Loans at a suitable Lending Installation
would violate any applicable law, rule, regulation, or directive, whether or not
having the force of law and gives notice of such determination to the Borrower
and the Agent, or (b) if the Required Lenders determine that (i) deposits of a
type and maturity appropriate to match fund Eurodollar Advances are not
available or (ii) the interest rate applicable to a Type of Advance does not
accurately reflect the cost of making or maintaining such Advance, then the
Agent shall suspend the availability of the affected Type of Advance from the
affected Lender, in the case of any occurrence set forth in clause (a), or from
all the Lenders, in the case of any occurrence set forth in clause (b), and, in
the case of any occurrence set forth in clause (a), require any affected
Eurodollar Advances to be repaid or converted to Alternate Base Rate Advances,
subject to the payment of any funding indemnification amounts required by
Section 3.4. Until the Lender giving the notice in (a) above has either
rescinded such notice or been replaced pursuant to Section 3.7, any Eurodollar
Loan which would otherwise have been required to be made by such Lender shall be
made as an Alternate Base Rate Advance.


                                      -26-
<PAGE>   34

         3.4. Funding Indemnification. If any payment of a Eurodollar Advance
occurs on a date which is not the last day of the applicable Interest Period,
whether because of acceleration, prepayment or otherwise, or a Eurodollar
Advance is not made on the date specified by the Borrower for any reason other
than default by any Lender, the Borrower will indemnify each Lender for any loss
or cost incurred by it resulting therefrom, including, without limitation, any
loss or cost in liquidating or employing deposits acquired to fund or maintain
such Eurodollar Advance.

         3.5. Taxes. (a) All payments by the Borrower to or for the account of
any Lender or the Agent hereunder or under any Note shall be made free and clear
of and without deduction for any and all Taxes. If the Borrower shall be
required by law to deduct any Taxes from or in respect of any sum payable
hereunder to any Lender or the Agent, (i) the sum payable shall be increased as
necessary so that after making all required deductions (including deductions
applicable to additional sums payable under this Section 3.5) such Lender or the
Agent (as the case may be) receives an amount equal to the sum it would have
received had no such deductions been made, (ii) the Borrower shall make such
deductions, (iii) the Borrower shall pay the full amount deducted to the
relevant authority in accordance with applicable law and (iv) the Borrower shall
furnish to the Agent the original copy of any receipt obtained by the Borrower
evidencing payment thereof within thirty (30) days after such receipt is
obtained.

         (b) In addition, the Borrower hereby agrees to pay any present or
future stamp or documentary taxes and any other excise or property taxes,
charges or similar levies which arise from any payment made hereunder or under
any Note or from the execution or delivery of, or otherwise with respect to,
this Agreement or any Note ("Other Taxes").

         (c) The Borrower hereby agrees to indemnify the Agent and each Lender
for the full amount of Taxes or Other Taxes (including, without limitation, any
Taxes or Other Taxes imposed on amounts payable under this Section 3.5) paid by
the Agent or such Lender and any liability (including penalties, interest and
expenses) arising therefrom or with respect thereto. Payments due under this
indemnification shall be made within thirty (30) days of the date the Agent or
such Lender makes demand therefor pursuant to Section 3.6.

         (d) Each Lender that is not incorporated under the laws of the United
States of America or a state thereof (each a "Non-U.S. Lender") agrees that it
will, not less than ten (10) Business Days after the date of this Agreement or,
if later, the date such Lender becomes a party hereto pursuant to Section 12.3,
(i) deliver to each of the Borrower and the Agent two duly completed copies of
United States Internal Revenue Service Form 1001 or 4224, certifying in either
case that such Lender is entitled to receive payments under this Agreement
without deduction or withholding of any United States federal income taxes, and
(ii) deliver to each of the Borrower and the Agent a United States Internal
Revenue Form W-8 or W-9, as the case may be, and certify that it is entitled to
an exemption from United States backup withholding tax. Each Non-U.S. Lender
further undertakes to deliver to each of the Borrower and the Agent (x) renewals
or additional copies of such form (or any successor form) on or before the date
that such form expires or becomes obsolete, and (y) after the occurrence of any
event requiring a change in the most recent forms so delivered by it, such
additional forms or amendments thereto as may be reasonably requested by the
Borrower or the Agent. All forms or amendments described in the preceding
sentence shall certify that such


                                      -27-
<PAGE>   35

Lender is entitled to receive payments under this Agreement without deduction or
withholding of any United States federal income taxes, unless an event
(including without limitation any change in treaty, law or regulation) has
occurred prior to the date on which any such delivery would otherwise be
required which renders all such forms inapplicable or which would prevent such
Lender from duly completing and delivering any such form or amendment with
respect to it and such Lender advises the Borrower and the Agent that it is not
capable of receiving payments without any deduction or withholding of United
States federal income tax.

         (e) For any period during which a Non-U.S. Lender has failed to provide
the Borrower with an appropriate form pursuant to clause (d) above (unless such
failure is due to a change in treaty, law or regulation, or any change in the
interpretation or administration thereof by any governmental authority,
occurring subsequent to the date on which a form originally was required to be
provided), such Non-U.S. Lender shall not be entitled to indemnification under
this Section 3.5 with respect to Taxes imposed by the United States; provided
that, should a Non-U.S. Lender which is otherwise exempt from or subject to a
reduced rate of withholding tax become subject to Taxes because of its failure
to deliver a form required under clause (d), above, the Borrower shall take such
steps as such Non-U.S. Lender shall reasonably request to assist such Non-U.S.
Lender to recover such Taxes.

         (f) Any Lender that is entitled to an exemption from or reduction of
withholding tax with respect to payments under this Agreement or any Note
pursuant to the law of any relevant jurisdiction or any treaty shall deliver to
the Borrower (with a copy to the Agent), at the time or times prescribed by
applicable law, such properly completed and executed documentation prescribed by
applicable law as will permit such payments to be made without withholding or at
a reduced rate.

         3.6. Lender Statements; Survival of Indemnity. To the extent reasonably
possible, each Lender shall designate an alternate Lending Installation with
respect to its Eurodollar Loans to reduce any liability of the Borrower to such
Lender under Sections 3.1, 3.2 and 3.5 or to avoid the unavailability of
Eurodollar Advances under Section 3.3, so long as such designation is not, in
the reasonable judgment of such Lender, disadvantageous to such Lender. Each
Lender shall deliver a written statement of such Lender to the Borrower (with a
copy to the Agent) as to the amount due, if any, under Section 3.1, 3.2, 3.4 or
3.5. Such written statement shall set forth in reasonable detail the
calculations upon which such Lender determined such amount and shall be final,
conclusive and binding on the Borrower in the absence of manifest error.
Determination of amounts payable under such Sections in connection with a
Eurodollar Loan shall be calculated as though each Lender funded its Eurodollar
Loan through the purchase of a deposit of the type and maturity corresponding to
the deposit used as a reference in determining the Eurodollar Rate applicable to
such Loan, whether in fact that is the case or not. Unless otherwise provided
herein, the amount specified in the written statement of any Lender shall be
payable on demand after receipt by the Borrower of such written statement. The
obligations of the Borrower under Sections 3.1, 3.2, 3.4 and 3.5 shall survive
payment of the Obligations and termination of this Agreement.

         3.7. Substitution of Lenders. Any Lender (a) claiming any additional
amounts payable pursuant to Section 3.1, 3.2, or 3.5, (b) which gives a notice
described in Section 3.3, or (c) declining to approve of an Extension Request
pursuant to Section 2.20, shall, so long as no Default or Unmatured Default has
occurred and is continuing, upon the written request of the Borrower


                                      -28-
<PAGE>   36

delivered to such Lender and the Agent, assign, pursuant to and in accordance
with the provisions of Section 12.3, all of its rights and obligations under
this Agreement and under the Loan Documents to another Lender or to a commercial
bank, other financial institution, commercial finance company or other business
lender selected by the Borrower and reasonably acceptable to the Agent that (a)
has agreed not to claim any additional amounts under Section 3.1, 3.2 or 3.5
with respect to some or all of the costs or regulatory charges that gave rise to
such assigning Lender's claim for such compensation, (b) has not made a
determination of the type described in Section 3.3, or (c) has not declined to
approve of an Extension Request pursuant to Section 2.20, as applicable, in
consideration for (a) the payment by such assignee to such assigning Lender of
the principal of, and interest accrued and unpaid to the date of such assignment
on, the Loans held by such assigning Lender, (b) the payment by the Borrower to
such assigning Lender of any and all other amounts owing to such assigning
Lender under any provision of this Agreement accrued and unpaid to the date of
such assignment and (c) the payment by the Borrower to such assigning Lender of
any amounts which would be payable to such Lender pursuant to Section 3.4 were
such assignment treated as a repayment of such Loans.

constitute a representation and warranty by the Borrower that the conditions
contained in Section 4.2 (a) and (b) have been satisfied. Any Lender may require
a duly completed compliance certificate in substantially the form of Exhibit B
hereto as a condition to making an Advance or issuing a Facility Letter of
Credit.

                                    ARTICLE V

                         REPRESENTATIONS AND WARRANTIES

         The Borrower represents and warrants to the Lenders that, both before
and after giving effect to the Closing Transactions:

         5.1. Existence and Standing. Each of the Borrower and its Subsidiaries
is a corporation, partnership (in the case of Subsidiaries only) or limited
liability company (in the case of Subsidiaries only) duly and properly
incorporated or organized, as the case may be, validly existing and (to the
extent such concept applies to such entity) in good standing under the laws of
its jurisdiction of incorporation or organization and has all requisite
authority to conduct its business in each jurisdiction in which its business is
conducted.

         5.2. Authorization and Validity. The Borrower and each Guarantor has
the power and authority and legal right to execute and deliver the Loan
Documents and other Transaction Documents to which it is a party and to perform
its obligations thereunder. The execution and delivery by the Borrower and each
Guarantor of the Loan Documents and other Transaction Documents to which it is a
party and the performance of its respective obligations thereunder have been
duly authorized by proper corporate proceedings, and the Loan Documents and
other Transaction Documents to which the Borrower or any Guarantor is a party
constitute legal, valid and binding obligations of the Borrower or such
Guarantor, as applicable, enforceable against the Borrower or such Guarantor, as
applicable, in accordance with their terms, except as enforceability may be
limited by bankruptcy, insolvency or similar laws affecting the enforcement of
creditors' rights generally.

         5.3. No Conflict; Government Consent. Neither the execution and
delivery by the Borrower or any Guarantor of the Loan Documents and other
Transaction Documents to which it is a party, nor the consummation of the
transactions therein contemplated, nor compliance with the provisions thereof
will violate (i) any law, rule, regulation, order, writ, judgment, injunction,
decree or award binding on the Borrower or any of its Subsidiaries or (ii) the
Borrower's or any Subsidiary's articles or certificate of incorporation,
partnership agreement, certificate of partnership, articles or certificate of
organization, by-laws, or operating or other management agreement, as the case
may be, or (iii) the provisions of any indenture, instrument or agreement to
which the Borrower or any of its Subsidiaries is a party or is subject, or by
which it, or its Property, is bound, or conflict with or constitute a default
thereunder, or result in, or require, the creation or imposition of any Lien in,
of or on the Property of the Borrower or a Subsidiary pursuant to the terms of
any such indenture, instrument or agreement. No order, consent, adjudication,
approval, license, authorization, or validation of, or filing, recording or
registration with, or exemption by, or other action in respect of any
governmental or public body or authority, or any subdivision thereof, which has
not been obtained by the Borrower or any of its Subsidiaries, is required to be
obtained by the Borrower or any of its Subsidiaries in connection with the
execution and delivery of the Loan Documents and other Transaction Documents,
the borrowings under this Agreement, the payment and performance by the Borrower
of the Obligations or the legality, validity, binding effect or enforceability
of any of the Loan Documents. Neither the Borrower nor any Subsidiary is in
default under or in violation


                                      -34-
<PAGE>   42

of any foreign, federal, state or local law, rule, regulation, order, writ,
judgment, injunction, decree or award binding upon or applicable to the Borrower
or such Subsidiary, in each case the consequences of which default or violation
could reasonably be expected to have a Material Adverse Effect.

         5.4. Financial Statements. The December 31, 1997 audited consolidated
financial statements and the June 30, 1998 unaudited consolidated financial
statements of (a) the Borrower and its Subsidiaries and (b) LTI and its
Subsidiaries heretofore delivered to the Lenders were prepared in accordance
with generally accepted accounting principles in effect on the date such
statements were prepared and fairly present in all material respects the
consolidated financial condition and results of operations of the Borrower and
its Subsidiaries or LTI and its Subsidiaries, as applicable, at such date and
the consolidated results of their operations for the periods then ended. The pro
forma balance sheet and related profit and loss statement (the "Pro Forma") of
the Borrower and its Subsidiaries on a consolidated basis as of September 30,
1998 is attached hereto as Schedule 5.4. As of the date of this Agreement, the
Pro Forma is complete and accurate and fairly represents in all material
respects the Borrower's and the Subsidiaries' assets, liabilities, financial
condition and results of operations on a consolidated basis in accordance with
Agreement Accounting Principles, consistently applied, and taking into account
the Closing Transactions, the consummation of the Merger and the other
transactions and actions contemplated by this Agreement, the Loan Documents and
the Transaction Documents.

         5.5. Material Adverse Change. Since June 30, 1998 there has been no
change in the business, Property, financial condition or results of operations
of the Borrower and its Subsidiaries which could reasonably be expected to have
a Material Adverse Effect.

         5.6. Taxes. The Borrower and its Subsidiaries have filed all United
States federal tax returns and all other tax returns which are required to be
filed and have paid all taxes shown to be due pursuant to said returns or
pursuant to any assessment received by the Borrower or any of its Subsidiaries,
except such taxes, if any, the non-payment of which could not reasonably be
expected to have a Material Adverse Effect. As of the date hereof, the United
States income tax returns of the Borrower and its Subsidiaries have been audited
by the Internal Revenue Service through the Fiscal Year ended December 31, 1993
and those of LTI have been audited through the Fiscal Year ended December 31,
1989. No tax liens have been filed and no claims are being asserted with respect
to any such taxes. The charges, accruals and reserves on the books of the
Borrower and its Subsidiaries in respect of any taxes or other governmental
charges are adequate.

         5.7. Litigation and Contingent Obligations. There is no litigation,
arbitration, governmental investigation, proceeding or inquiry pending or, to
the knowledge of any of their officers, threatened against or affecting the
Borrower or any of its Subsidiaries which could reasonably be expected to have a
Material Adverse Effect or which seeks to prevent, enjoin or delay the making of
any Loans. Other than any liability incident to any litigation, arbitration or
proceeding which could not reasonably be expected to have a Material Adverse
Effect, the Borrower has no material contingent obligations not provided for or
disclosed in the financial statements referred to in Section 5.4.


                                      -35-
<PAGE>   43

         5.8. Subsidiaries. Schedule 5.8 contains an accurate list of all
Subsidiaries of the Borrower as of the date of this Agreement, setting forth
their respective jurisdictions of organization and the percentage of their
respective capital stock or other ownership interests owned by the Borrower or
other Subsidiaries. All of the issued and outstanding shares of capital stock or
other ownership interests of such Subsidiaries have been (to the extent such
concepts are relevant with respect to such ownership interests) duly authorized
and issued and are fully paid and non-assessable.

         5.9. ERISA. The Unfunded Liabilities of all Single Employer Plans do
not in the aggregate exceed $5,000,000. Neither the Borrower nor any other
member of the Controlled Group has incurred, or is reasonably expected to incur,
any withdrawal liability to Multiemployer Plans. Each Plan complies in all
material respects with all applicable requirements of law and regulations, no
Reportable Event has occurred with respect to any Plan, neither the Borrower nor
any other member of the Controlled Group has withdrawn from any Plan or
initiated steps to do so, and no steps have been taken to reorganize or
terminate any Plan.

         5.10. Defaults. No Default or Unmatured Default has occurred and is
continuing.

         5.11. Regulation U. Margin stock (as defined in Regulation U)
constitutes less than 25% of the value of those assets of the Borrower and its
Subsidiaries which are subject to any limitation on sale, pledge, or other
restriction hereunder. Neither the making of any Advance or issuance of any
Facility Letters of Credit hereunder, the use of the proceeds thereof, nor any
other aspect of the financing of the Acquisition, will violate or be
inconsistent with the provisions of Regulation T, Regulation U or Regulation X.

         5.12. Material Agreements. Neither the Borrower nor any Subsidiary is a
party to any agreement or instrument or subject to any charter or other
corporate restriction which could reasonably be expected to have a Material
Adverse Effect. Neither the Borrower nor any Subsidiary is in default in the
performance, observance or fulfillment of any of the obligations, covenants or
conditions contained in (i) any agreement to which it is a party, which default
could reasonably be expected to have a Material Adverse Effect or (ii) any
agreement or instrument evidencing or governing Indebtedness.

         5.13. Compliance With Laws. The Borrower and its Subsidiaries have
complied with all applicable statutes, rules, regulations, orders and
restrictions of any domestic or foreign government or any instrumentality or
agency thereof having jurisdiction over the conduct of their respective
businesses or the ownership of their respective Property except for any failure
to comply with any of the foregoing which could not reasonably be expected to
have a Material Adverse Effect.

         5.14. Ownership of Properties. Except as set forth on Schedule 5.14, on
the date of this Agreement, the Borrower and its Subsidiaries will have good
title, free of all Liens other than those permitted by Section 6.16, to all of
the Property and assets reflected in the Borrower's most recent consolidated
financial statements provided to the Agent as owned by the Borrower and its
Subsidiaries.


                                      -36-
<PAGE>   44

         5.15. Plan Assets; Prohibited Transactions. The Borrower is not an
entity deemed to hold "plan assets" within the meaning of 29 C.F.R. Section
2510.3-101 of an employee benefit plan (as defined in Section 3(3) of ERISA)
which is subject to Title I of ERISA or any plan (within the meaning of Section
4975 of the Code), and neither the execution of this Agreement nor the making of
Loans hereunder gives rise to a prohibited transaction within the meaning of
Section 406 of ERISA or Section 4975 of the Code.

         5.16. Environmental Matters. In the ordinary course of its business,
the officers of the Borrower consider the effect of Environmental Laws on the
business of the Borrower and its Subsidiaries, in the course of which they
identify and evaluate potential risks and liabilities accruing to the Borrower
due to Environmental Laws. On the basis of this consideration, the Borrower has
concluded that Environmental Laws cannot reasonably be expected to have a
Material Adverse Effect. Neither the Borrower nor any Subsidiary has received
any notice to the effect that its operations are not in material compliance with
any of the requirements of applicable Environmental Laws or are the subject of
any federal or state 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 could reasonably be
expected to have a Material Adverse Effect.

         5.17. Investment Company Act. Neither the Borrower nor any Subsidiary
is an "investment company" or a company "controlled" by an "investment company",
within the meaning of the Investment Company Act of 1940, as amended.

         5.18. Public Utility Holding Company Act. Neither the Borrower nor any
Subsidiary is a "holding company" or a "subsidiary company" of a "holding
company", or an "affiliate" of a "holding company" or of a "subsidiary company"
of a "holding company", within the meaning of the Public Utility Holding Company
Act of 1935, as amended.

         5.19. Acquisition Documents. The Borrower has delivered to the Agent
true, complete and correct copies of the Acquisition Documents (including all
schedules, exhibits, annexes, amendments, supplements, modifications, and all
other material documents delivered pursuant thereto or in connection therewith).
The Acquisition Documents as originally executed and delivered by the parties
thereto have not been amended, waived, supplemented or modified in any material
respect without the consent of the Required Lenders (such consent not to be
unreasonably withheld). Each of the representations and warranties given by the
parties thereto in the Merger Agreement is true and correct in all material
respects as of the date hereof. Neither the Borrower nor any other party thereto
is in default in the performance of or compliance with any provisions thereof.
The Merger Documents are, or if not yet executed, will be when executed, in form
and substance satisfactory for effecting the Merger pursuant to such agreements
under the laws of the State of Delaware.

         5.20. Year 2000. The Borrower and its Subsidiaries have made an
assessment of the Year 2000 Issues and have developed a program (the "Year 2000
Program") for remediating the Year 2000 Issues on a timely basis. Based on such
assessment and on the Year 2000 Program neither


                                      -37-
<PAGE>   45

the Borrower nor its Subsidiaries reasonably anticipate that Year 2000 Issues
will have a Material Adverse Effect.

         5.21. Disclosure. None of the (a) information, exhibits or reports
furnished or to be furnished by the Borrower or any Subsidiary to the Agent or
to any Lender in connection with the negotiation of the Loan Documents (taken as
a whole), or (b) representations or warranties of the Borrower or any Subsidiary
contained in this Agreement, the other Loan Documents, the Transaction Documents
or any other document, certificate or written statement furnished to the Agent
or the Lenders by or on behalf of the Borrower or any Subsidiary for use in
connection with the transactions contemplated by this Agreement or the
Transaction Documents, as the case may be, contained, contains or will contain
any untrue statement of a material fact or omitted, omits or will omit to state
a material fact necessary in order to make the statements contained herein or
therein not misleading at the time such representations or warranties were made
in light of the circumstances in which the same were made. The pro forma
financial information contained in such materials is based upon good faith
estimates and assumptions believed by the Borrower to be reasonable at the time
made.

                                   ARTICLE VI

                                    COVENANTS

         During the term of this Agreement, unless the Required Lenders shall

retained earnings and cash flows accompanied by a certificate of said
accountants that, in the course of the examination necessary for their
certification of the foregoing, they have obtained no knowledge of any Default
or Unmatured Default, or if, in the opinion of such accountants, any Default or
Unmatured Default shall exist, stating the nature and status thereof.

                    (b) As soon as practicable and in any event within sixty

such Fiscal Year to the end of such quarter, all certified by its chief
financial officer or treasurer.

by the Release by the Borrower, any of its Subsidiaries, or any other Person of
any Hazardous Materials into the environment or requiring that action be taken
to respond to or clean up a Release of Hazardous Materials into the environment,
and (ii) any notice, complaint or citation alleging any violation of any
Environmental Law or Environmental Permit by the Borrower or any of its
Subsidiaries which, in either case, could reasonably be expected to have a
Material Adverse Effect. Within ten (10) days of the Borrower or any Subsidiary
having knowledge of the proposal, enactment or promulgation of any Environmental
Law which could reasonably be expected to have a Material Adverse Effect, the
Borrower shall provide the Agent with written notice thereof.

                    (g) As soon as possible and in any event within ten (10)
days after the Borrower learns thereof, notice of the assertion or commencement

information) as the Agent or any Lender may from time to time reasonably
request.

         6.2. Use of Proceeds. The Borrower will, and will cause each Subsidiary
to, use the proceeds of the Advances to refinance indebtedness existing on the
initial Borrowing Date, for capital expenditures, to provide funds for the
Acquisition and the payment of related fees and


                                      -39-
<PAGE>   47

expenses and to meet the general corporate needs of the Borrower and its
Subsidiaries, including the financing of Purchases permitted hereby and
commercial paper back up. The Borrower will not, nor will it permit any
Subsidiary to, use any of the proceeds of the Advances or any Facility Letters
of Credit to purchase or carry any "margin stock" (as defined in Regulation U)
or to finance the Purchase of any Person in a transaction which has not been
approved and recommended by the board of directors or functional equivalent
thereof of such Person.

         6.3. Notice of Default. The Borrower will give prompt notice in writing
to the Agent upon any Authorized Officer obtaining knowledge of the occurrence

development, financial or other, relating specifically to the Borrower or any of
its Subsidiaries (and not of a general economic or political nature), including
without limitation developments with respect to Year 2000 Issues, which could
reasonably be expected to have a Material Adverse Effect.

Subsidiary to, carry on and conduct its business in substantially the same
manner and in substantially the same fields of enterprise as it is presently
conducted and to do all things necessary to remain duly incorporated, validly
existing and in good standing as a domestic corporation in its jurisdiction of
incorporation and maintain all requisite authority to conduct its business in
each jurisdiction in which its business is conducted.

         6.5. Taxes. The Borrower will, and will cause each Subsidiary to,
timely file complete and correct United States federal and applicable foreign,
state and local tax returns required by applicable law and pay when due all
taxes, assessments and governmental charges and levies upon it or its income,
profits or Property, except those which are being contested in good faith by
appropriate proceedings and with respect to which adequate reserves have been
set aside.

         6.6. Insurance. The Borrower will, and will cause each Subsidiary to,
maintain with financially sound and reputable insurance companies insurance on
all their Property in such amounts and covering such risks as is consistent with
sound business practice, and the Borrower will furnish to the Agent and any
Lender upon request full information as to the insurance carried; provided, that
nothing herein shall prohibit the Borrower and its Subsidiaries from maintaining
self-insurance in lieu of third party insurance consistent with past practices.

         6.7. Compliance with Laws. The Borrower will, and will cause each
Subsidiary to, comply with all laws, rules, regulations, orders, writs,
judgments, injunctions, decrees or awards to which it may be subject, the
failure to comply with which could reasonably be expected to have a Material
Adverse Effect.

         6.8. Maintenance of Properties. The Borrower will, and will cause each
Subsidiary to, do all things necessary to maintain, preserve, protect and keep
its Property in good repair, working order and condition, and make all necessary
and proper repairs, renewals and replacements so that its business carried on in
connection therewith may be properly conducted at all times.

         6.9. Inspection. The Borrower will, and will cause each Subsidiary to,
permit the Agent and the Lenders, by their respective representatives and
agents, to inspect any of the Property, corporate books and financial records of
the Borrower and each Subsidiary, to examine and make copies of the books of
accounts and other financial records of the Borrower and each Subsidiary, and to
discuss the affairs, finances and accounts of the Borrower and each Subsidiary
with, and to be advised as to the same by, their respective officers, directors
and independent public accountants at such reasonable times and intervals as the
Lenders may designate. The Borrower will keep or cause to be kept, and cause
each Subsidiary to keep or cause to be kept, appropriate records and books of
account in which complete entries are to be made reflecting its and their
business and financial transactions, such entries to be made in accordance with
Agreement Accounting Principles consistently applied.

         6.10. Capital Stock and Dividends. The Borrower will not, nor will it
permit any Subsidiary to, declare or pay any dividends or make any distributions

any options or other rights in respect thereof at any time outstanding, except
that (i) any Subsidiary may declare and pay dividends or make distributions to
the Borrower or to a Wholly-Owned Subsidiary of the Borrower and (ii) so long as

         6.12. Merger. The Borrower will not, nor will it permit any Subsidiary
to, merge or consolidate with or into any other Person, except that (a) a
Wholly-Owned Subsidiary may merge into the Borrower or any Wholly-Owned
Subsidiary of the Borrower, (b) the Borrower or any Subsidiary may merge or

otherwise disposed of pursuant to (a) or (b) above) does not constitute a
Substantial Portion of the Property of the Borrower and its Subsidiaries.

         6.14. Investments and Purchases. The Borrower will not, nor will it
permit any Subsidiary to, make or suffer to exist any Investments (including,
without limitation, loans and advances to, and other Investments in,
Subsidiaries), or commitments therefor, or to create any Subsidiary or to become
or remain a partner or member in any partnership, limited liability company or

preceding the date on which such determination is made may be Investments in
Persons which are not Subsidiaries.

         6.15. Contingent Obligations. The Borrower will not, nor will it permit

                 ACCELERATION, WAIVERS, AMENDMENTS AND REMEDIES

         8.1. Acceleration. If any Default described in Section 7.6 or 7.7
occurs with respect to the Borrower, the obligations of the Lenders to make
Loans or issue Facility Letters of Credit hereunder shall automatically
terminate and the Obligations shall immediately become due and payable without
any election or action on the part of the Agent or any Lender. If any other
Default occurs, the Required Lenders (or the Agent with the consent of the
Required Lenders) may terminate


                                      -49-
<PAGE>   57

or suspend the obligations of the Lenders to make Loans or issue Facility
Letters of Credit hereunder, or declare the Obligations to be due and payable,
or both, whereupon the Obligations shall become immediately due and payable,
without presentment, demand, protest or notice of any kind, all of which the
Borrower hereby expressly waives. In addition to the foregoing, following the
occurrence and during the continuance of a Default, so long as any Facility
Letter of Credit has not been fully drawn and has not been canceled or expired
by its terms, upon demand by the Agent, the Borrower shall deposit in an account
(the "Letter of Credit Cash Collateral Account") maintained with First Chicago
in the name of the Agent, for the ratable benefit of the Lenders, the Issuer and
the Agent, cash in an amount equal to the aggregate undrawn face amount of all
outstanding Facility Letters of Credit and all fees and other amounts due or
which may become due with respect thereto. The Borrower shall have no control
over funds in the Letter of Credit Cash Collateral Account, which funds shall be
invested by the Agent from time to time in its discretion in certificates of
deposit of First Chicago having a maturity not exceeding thirty (30) days. Such
funds shall be promptly applied by the Agent to reimburse the Issuer for drafts
drawn from time to time under the Facility Letters of Credit. Such funds, if
any, remaining in the Letter of Credit Cash Collateral Account following the
payment of all Obligations in full or the earlier termination of all Defaults
shall, unless the Agent is otherwise directed by a court of competent
jurisdiction, be promptly paid over to the Borrower.

         If, within thirty (30) days after acceleration of the maturity of the
Obligations or termination of the obligations of the Lenders to make Loans
hereunder as a result of any Default (other than any Default as described in
Section 7.6 or 7.7 with respect to the Borrower) and before any judgment or
decree for the payment of the Obligations due shall have been obtained or
entered, the Required Lenders (in their sole discretion) shall so direct, the
Agent shall, by notice to the Borrower, rescind and annul such acceleration
and/or termination.

         8.2. Amendments. Subject to the provisions of this Article VIII, the
Required Lenders (or the Agent with the consent in writing of the Required
Lenders) and the Borrower may enter into agreements supplemental hereto for the
purpose of adding or modifying any provisions to the Loan Documents or changing
in any manner the rights of the Lenders or the Borrower hereunder or waiving any
Default hereunder; provided, however, that no such supplemental agreement shall,
without the consent of each Lender:

                  (a) Extend the final maturity of any Loan or forgive all or
any portion of the principal amount thereof, or reduce the rate or extend the
time of payment of interest or fees hereunder;

                  (b) Reduce the percentage specified in the definition of
Required Lenders;

                  (c) Reduce the amount of or extend the date for the mandatory
payments required under Section 2.1(b);

                  (d) Extend the Facility Termination Date, permit any Facility
Letter of Credit to have an expiry date beyond a date five (5) Business Days
prior to the Facility Termination Date, or increase the amount of the Commitment
of any Lender hereunder;


                                      -50-
<PAGE>   58

                  (e) Amend this Section 8.2;

                  (f) Release any Guarantor from the Subsidiary Guaranty; or

                  (g) Permit any assignment by the Borrower of its Obligations
or its rights hereunder.

No amendment of any provision of this Agreement relating to the Agent shall be
effective without the written consent of the Agent. The Agent may waive payment
of the fee required under Section 12.3.2 without obtaining the consent of any
other party to this Agreement.

         8.3. Preservation of Rights. No delay or omission of the Lenders or the
Agent to exercise any right under the Loan Documents shall impair such right or
be construed to be a waiver of any Default or an acquiescence therein, and the
making of a Loan notwithstanding the existence of a Default or the inability of
the Borrower to satisfy the conditions precedent to such Loan shall not
constitute any waiver or acquiescence. Any single or partial exercise of any
such right shall not preclude other or further exercise thereof or the exercise
of any other right, and no waiver, amendment or other variation of the terms,
conditions or provisions of the Loan Documents whatsoever shall be valid unless
in writing signed by the Lenders required pursuant to Section 8.2, and then only
to the extent in such writing specifically set forth. All remedies contained in
the Loan Documents or by law afforded shall be cumulative and all shall be
available to the Agent and the Lenders until the Obligations have been paid in
full.

the Borrower contained in this Agreement or of the Borrower or any Subsidiary
contained in any Loan Document shall survive delivery of the Notes (if any) and
the making of the Loans herein contemplated.

         9.2. Governmental Regulation. Anything contained in this Agreement to
the contrary notwithstanding, no Lender shall be obligated to extend credit to
the Borrower in violation of any limitation or prohibition provided by any
applicable statute or regulation.

         9.3. Headings. Section headings in the Loan Documents are for
convenience of reference only, and shall not govern the interpretation of any of
the provisions of the Loan Documents.

         9.4. Entire Agreement. The Loan Documents embody the entire agreement
and understanding among the Borrower, the Agent and the Lenders and supersede
all prior agreements and understandings among the Borrower, the Agent and the
Lenders relating to the subject matter thereof other than the fee letter dated
July 6, 1998 in favor of First Chicago and the Arranger.

         9.5. Numbers of Documents. All statements, notices, closing documents,
and requests hereunder shall be furnished to the Agent with sufficient
counterparts so that the Agent may furnish one to each of the Lenders.

         9.6. Several Obligations; Benefits of this Agreement. The respective
obligations of the Lenders hereunder are several and not joint and no Lender
shall be the partner or agent of any other (except to the extent to which the
Agent is authorized to act as such). The failure of any Lender to perform any of
its obligations hereunder shall not relieve any other Lender from any of its
obligations hereunder. This Agreement shall not be construed so as to confer any
right or benefit upon any Person other than the parties to this Agreement and
their respective successors and assigns, provided, however, that the parties
hereto expressly agree that the Arranger shall enjoy the benefits of the
provisions of Sections 9.6, 9.10 and 10.11 to the extent specifically set forth
therein and shall have the right to enforce such provisions on its own behalf
and in its own name to the same extent as if it were a party to this Agreement.

         9.7. Expenses; Indemnification. (a) The Borrower shall reimburse the
Agent and the Arranger for any reasonable costs, internal charges and
out-of-pocket expenses (including reasonable attorneys' fees and time charges of
attorneys for the Agent, which attorneys may be employees of the Agent) paid or
incurred by the Agent or the Arranger in connection with the preparation,
negotiation, execution, delivery, syndication, review, amendment, modification,
and administration of the Loan Documents. The Borrower also agrees to reimburse
the Agent, the Arranger and the Lenders for any reasonable costs, internal
charges and out-of-pocket expenses (including reasonable attorneys' fees and
time charges of attorneys for the Agent, the Arranger and the Lenders, which
attorneys may be employees of the Agent, the Arranger or the respective Lenders)
paid or incurred by the Agent, the Arranger or any Lender in connection with the
collection and enforcement of the Loan Documents.

         (b) The Borrower hereby further agrees to indemnify the Agent, the
Arranger and each Lender, its directors, officers and employees against all
losses, claims, damages, penalties, judgments, liabilities and expenses
(including, without limitation, all expenses of litigation or preparation
therefor whether or not the Agent, the Arranger or any Lender is a party
thereto) which any of them may pay or incur arising out of or relating to this
Agreement, the other Loan Documents, the transactions contemplated hereby or the
direct or indirect application or proposed application of the proceeds of any
Loan hereunder except to the extent that they resulted from the gross negligence
or willful misconduct of the party seeking indemnification. The obligations of
the Borrower under this Section 9.7 shall survive the termination of this
Agreement.

         9.8. Accounting. Except as provided to the contrary herein, all
accounting terms used herein shall be interpreted and all accounting
determinations hereunder shall be made in accordance with Agreement Accounting
Principles.

         9.9. Severability of Provisions. Any provision in any Loan Document
that is held to be inoperative, unenforceable, or invalid in any jurisdiction
shall, as to that jurisdiction, be inoperative, unenforceable, or invalid
without affecting the remaining provisions in that jurisdiction or the


                                      -52-
<PAGE>   60

operation, enforceability, or validity of that provision in any other
jurisdiction, and to this end the provisions of all Loan Documents are declared
to be severable.

         9.10. Nonliability of Lenders. The relationship between the Borrower on
the one hand and the Lenders and the Agent on the other hand shall be solely
that of borrower and lender. Neither the Agent, the Arranger nor any Lender
shall have any fiduciary responsibilities to the Borrower. Neither the Agent,
the Arranger nor any Lender undertakes any responsibility to the Borrower to
review or inform the Borrower of any matter in connection with any phase of the
Borrower's business or operations. The Borrower agrees that neither the Agent,
the Arranger nor any Lender shall have liability to the Borrower (whether
sounding in tort, contract or otherwise) for losses suffered by the Borrower in
connection with, arising out of, or in any way related to, the transactions
contemplated and the relationship established by the Loan Documents, or any act,
omission or event occurring in connection therewith, unless such losses resulted
from the gross negligence or willful misconduct of the party from which recovery
is sought. Neither the Agent, the Arranger nor any Lender shall have any
liability with respect to, and the Borrower hereby waives, releases and agrees
not to sue for, any special, indirect or consequential damages suffered by the
Borrower in connection with, arising out of, or in any way related to the Loan
Documents or the transactions contemplated thereby.

         9.11. Confidentiality. Each Lender agrees to hold any confidential
information which it may receive from the Borrower pursuant to this Agreement in
confidence, except for disclosure (i) to its Affiliates and to other Lenders and
their respective Affiliates, (ii) to legal counsel, accountants, and other
professional advisors to that Lender or to a Transferee, (iii) to regulatory
officials, (iv) to any Person as requested pursuant to or as required by law,
regulation, or legal process, (v) to any Person in connection with any legal
proceeding to which that Lender is a party (in which case prior notice of such
disclosure shall be given to the Borrower to the extent practicable and not
otherwise prohibited under such proceeding), and (vi) permitted by Section 12.4.

         9.12. Nonreliance. Each Lender hereby represents that it is not relying
on or looking to any margin stock (as defined in Regulation U of the Board of
Governors of the Federal Reserve System) for the repayment of the Loans provided
for herein.

         9.13. Disclosure. The Borrower and each Lender hereby (a) acknowledge
and agree that First Chicago and/or its Affiliates from time to time may hold
other investments in, make other loans to or have other relationships with the
Borrower and its Affiliates, and (b) waive any liability of First Chicago or
such Affiliate to the Borrower or any Lender, respectively, arising out of or
resulting from such investments, loans or relationships other than liabilities
arising out of the gross negligence or willful misconduct of First Chicago or
its Affiliates.

                                    ARTICLE X

                                    THE AGENT

         10.1. Appointment; Nature of Relationship. The First National Bank of
Chicago is hereby appointed by each of the Lenders as its contractual
representative (herein referred to as the "Agent") hereunder and under each
other Loan Document, and each of the Lenders irrevocably authorizes the Agent to
act as the contractual representative of such Lender with the rights and duties
expressly set forth herein and in the other Loan Documents. The Agent agrees to
act as such contractual representative upon the express conditions contained in
this Article X. Notwithstanding the use of the defined term "Agent," it is
expressly understood and agreed that the Agent shall not have any fiduciary
responsibilities to any Lender by reason of this Agreement or any other Loan
Document and that the Agent is merely acting as the contractual representative
of the Lenders with only those duties as are expressly set forth in this
Agreement and the other Loan Documents. In its capacity as the Lenders'
contractual representative, the Agent (i) does not hereby assume any fiduciary
duties to any of the Lenders, (ii) is a "representative" of the Lenders within
the meaning of Section 9-105 of the Uniform Commercial Code and (iii) is acting
as an independent contractor, the rights and duties of which are limited to
those expressly set forth in this Agreement and the other Loan Documents. Each
of the Lenders hereby agrees to assert no claim against the Agent on any agency
theory or any other theory of liability for breach of fiduciary duty, all of
which claims each Lender hereby waives.

         10.2. Powers. The Agent shall have and may exercise such powers under
the Loan Documents as are specifically delegated to the Agent by the terms of
each thereof, together with such powers as are reasonably incidental thereto.
The Agent shall have no implied duties to the Lenders, or any obligation to the
Lenders to take any action thereunder except any action specifically provided by
the Loan Documents to be taken by the Agent.

         10.3. General Immunity. Neither the Agent nor any of its directors,
officers, agents or employees shall be liable to the Borrower, the Lenders or
any Lender for any action taken or omitted to be taken by it or them hereunder
or under any other Loan Document or in connection herewith or therewith except
to the extent such action or inaction is determined in a final non-appealable
judgment by a court of competent jurisdiction to have arisen from the gross
negligence or willful misconduct of such Person.

         10.4. No Responsibility for Loans, Recitals, etc. Neither the Agent nor
any of its directors, officers, agents or employees shall be responsible for or
have any duty to ascertain, inquire into, or verify (a) any statement, warranty
or representation made in connection with any Loan Document or any borrowing
hereunder; (b) the performance or observance of any of the covenants or
agreements of any obligor under any Loan Document, including, without
limitation, any agreement by an obligor to furnish information directly to each
Lender; (c) the satisfaction of any condition specified in Article IV, except
receipt of items required to be delivered solely to the Agent; (d) the existence
or possible existence of any Default or Unmatured Default; (e) the validity,
enforceability, effectiveness, sufficiency or genuineness of any Loan Document
or any other instrument or writing furnished in connection therewith; (f) the
value, sufficiency, creation, perfection or priority of any


                                      -54-
<PAGE>   62

Lien in any collateral security; or (g) the financial condition of the Borrower
or any guarantor of any of the Obligations or of any of the Borrower's or any
such guarantor's respective Subsidiaries. The Agent shall have no duty to
disclose to the Lenders information that is not required to be furnished by the
Borrower to the Agent at such time, but is voluntarily furnished by the Borrower
to the Agent (either in its capacity as Agent or in its individual capacity).

         10.5. Action on Instructions of Lenders. The Agent shall in all cases
be fully protected in acting, or in refraining from acting, hereunder and under
any other Loan Document in accordance with written instructions signed by the
Required Lenders, and such instructions and any action taken or failure to act
pursuant thereto shall be binding on all of the Lenders. The Lenders hereby
acknowledge that the Agent shall be under no duty to take any discretionary
action permitted to be taken by it pursuant to the provisions of this Agreement
or any other Loan Document unless it shall be requested in writing to do so by
the Required Lenders. The Agent shall be fully justified in failing or refusing
to take any action hereunder and under any other Loan Document unless it shall
first be indemnified to its satisfaction by the Lenders pro rata against any and
all liability, cost and expense that it may incur by reason of taking or
continuing to take any such action.

         10.6. Employment of Agents and Counsel. The Agent may execute any of
its duties as Agent hereunder and under any other Loan Document by or through
employees, agents, and attorneys-in-fact and shall not be answerable to the
Lenders, except as to money or securities received by it or its authorized
agents, for the default or misconduct of any such agents or attorneys-in-fact
selected by it with reasonable care. The Agent shall be entitled to advice of
counsel concerning the contractual arrangement between the Agent and the Lenders
and all matters pertaining to the Agent's duties hereunder and under any other
Loan Document.

         10.7. Reliance on Documents; Counsel. The Agent shall be entitled to
rely upon any Note, notice, consent, certificate, affidavit, letter, telegram,
statement, paper or document believed by it to be genuine and correct and to
have been signed or sent by the proper person or persons, and, in respect to
legal matters, upon the opinion of counsel selected by the Agent, which counsel
may be employees of the Agent.

         10.8. Agent's Reimbursement and Indemnification. The Lenders agree to
reimburse and indemnify the Agent ratably in proportion to their respective
Commitments (or, if the Commitments have been terminated, in proportion to their
Commitments immediately prior to such termination) (i) for any amounts not
reimbursed by the Borrower for which the Agent is entitled to reimbursement by
the Borrower under the Loan Documents, (ii) for any other expenses incurred by
the Agent on behalf of the Lenders, in connection with the preparation,
execution, delivery, administration and enforcement of the Loan Documents
(including, without limitation, for any expenses incurred by the Agent in
connection with any dispute between the Agent and any Lender or between two or
more of the Lenders) and (iii) for any liabilities, obligations, losses,
damages, penalties, actions, judgments, suits, costs, expenses or disbursements
of any kind and nature whatsoever which may be imposed on, incurred by or
asserted against the Agent in any way relating to or arising out of the Loan
Documents or any other document delivered in connection therewith or the
transactions contemplated thereby (including, without limitation, for any such
amounts incurred by or asserted against the Agent in connection with any dispute
between the Agent and any Lender or between two 


                                      -55-
<PAGE>   63
or more of the Lenders), or the enforcement of any of the terms of the Loan
Documents or of any such other documents, provided that no Lender shall be
liable for any of the foregoing to the extent any of the foregoing is found in a
final non-appealable judgment by a court of competent jurisdiction to have
resulted from the gross negligence or willful misconduct of the Agent. The
obligations of the Lenders under this Section 10.8 shall survive payment of the
Obligations and termination of this Agreement.

         10.9. Notice of Default. The Agent shall not be deemed to have
knowledge or notice of the occurrence of any Default or Unmatured Default
hereunder unless the Agent has received written notice from a Lender or the
Borrower referring to this Agreement describing such Default or Unmatured
Default and stating that such notice is a "notice of default". In the event that
the Agent receives such a notice, the Agent shall give prompt notice thereof to
the Lenders.

         10.10. Rights as a Lender. In the event the Agent is a Lender, the
Agent shall have the same rights and powers hereunder and under any other Loan
Document with respect to its Commitment and its Loans as any Lender and may
exercise the same as though it were not the Agent, and the term "Lender" or
"Lenders" shall, at any time when the Agent is a Lender, unless the context
otherwise indicates, include the Agent in its individual capacity. The Agent and
its Affiliates may accept deposits from, lend money to, and generally engage in
any kind of trust, debt, equity or other transaction, in addition to those
contemplated by this Agreement or any other Loan Document, with the Borrower or
any of its Subsidiaries in which the Borrower or such Subsidiary is not
restricted hereby from engaging with any other Person.

         10.11. Lender Credit Decision. Each Lender acknowledges that it has,
independently and without reliance upon the Agent, the Arranger or any other
Lender and based on the financial statements prepared by the Borrower and such
other documents and information as it has deemed appropriate, made its own
credit analysis and decision to enter into this Agreement and the other Loan
Documents. Each Lender also acknowledges that it will, independently and without
reliance upon the Agent, the Arranger or any other Lender and based on such
documents and information as it shall deem appropriate at the time, continue to
make its own credit decisions in taking or not taking action under this
Agreement and the other Loan Documents.

         10.12. Successor Agent. The Agent may resign at any time by giving
written notice thereof to the Lenders and the Borrower, such resignation to be
effective upon the appointment of a successor Agent or, if no successor Agent
has been appointed, forty-five (45) days after the retiring Agent gives notice
of its intention to resign. The Agent may be removed at any time with or without
cause by written notice received by the Agent from the Required Lenders, such
removal to be effective on the date specified by the Required Lenders. Upon any
such resignation or removal, the Required Lenders shall have the right to
appoint, on behalf of the Borrower and the Lenders, a successor Agent. If no
successor Agent shall have been so appointed by the Required Lenders within
thirty (30) days after the resigning Agent's giving notice of its intention to
resign, then the resigning Agent may appoint, on behalf of the Borrower and the
Lenders, a successor Agent. Notwithstanding the previous sentence, the Agent may
at any time without the consent of the Borrower or any Lender, appoint any of
its Affiliates which is a commercial bank as a successor Agent hereunder. If the
Agent has resigned or been removed and no successor Agent has been


                                      -56-
<PAGE>   64

appointed, the Lenders may perform all the duties of the Agent hereunder and the
Borrower shall make all payments in respect of the Obligations to the applicable
Lender and for all other purposes shall deal directly with the Lenders. No
successor Agent shall be deemed to be appointed hereunder until such successor
Agent has accepted the appointment. Any such successor Agent shall be a
commercial bank having capital and retained earnings of at least $100,000,000.
Upon the acceptance of any appointment as Agent hereunder by a successor Agent,
such successor Agent shall thereupon succeed to and become vested with all the
rights, powers, privileges and duties of the resigning or removed Agent. Upon
the effectiveness of the resignation or removal of the Agent, the resigning or
removed Agent shall be discharged from its duties and obligations hereunder and
under the Loan Documents. After the effectiveness of the resignation or removal
of an Agent, the provisions of this Article X shall continue in effect for the
benefit of such Agent in respect of any actions taken or omitted to be taken by
it while it was acting as the Agent hereunder and under the other Loan
Documents. In the event that there is a successor to the Agent by merger, or the
Agent assigns its duties and obligations to an Affiliate pursuant to this
Section 10.12, then the term "Corporate Base Rate" as used in this Agreement
shall mean the prime rate, base rate or other analogous rate of the new Agent.

         10.13. Agent's Fee. The Borrower agrees to pay to the Agent, for its
own account, the fees agreed to by the Borrower and the Agent pursuant to that
certain fee letter dated July 6, 1998, or as otherwise agreed from time to time.

         10.14. Delegation to Affiliates. The Borrower and the Lenders agree
that the Agent may delegate any of its duties under this Agreement to any of its
Affiliates. Any such Affiliate (and such Affiliate's directors, officers, agents
and employees) which performs duties in connection with this Agreement shall be
entitled to the same benefits of the indemnification, waiver and other
protective provisions to which the Agent is entitled under Articles IX and X.

         10.15. Documentation Agent; Syndication Agent. None of the Lenders
identified on the facing page or signature pages of this Agreement as the
"documentation agent" or the "syndication agent" shall have any right, power,
obligation, liability, responsibility or duty under this Agreement other than
those applicable to all Lenders as such. Without limiting the foregoing, none of
the Lenders so identified as the "documentation agent" or "syndication agent"
shall have or be deemed to have any fiduciary relationship with any Lender. Each
Lender acknowledges that it has not relied, and will not rely, on any of the
Lenders so identified in deciding to enter into this Agreement or in taking or
not taking action hereunder.

                                   ARTICLE XI

                            SETOFF; RATABLE PAYMENTS

         11.1. Setoff. In addition to, and without limitation of, any rights of
the Lenders under applicable law, if the Borrower becomes insolvent, however
evidenced, or any Default occurs and for so long as such Default is continuing,
any and all deposits (including all account balances, whether provisional or
final and whether or not collected or available) and any other Indebtedness


                                      -57-
<PAGE>   65

at any time held or owing by any Lender to or for the credit or account of the
Borrower may be offset and applied toward the payment of the Obligations owing
to such Lender, whether or not the Obligations, or any part hereof, shall then
be due.

         11.2. Ratable Payments. If any Lender, whether by setoff or otherwise,
has payment made to it upon its Loans (other than payments received pursuant to
Section 3.1, 3.2, 3.4 or 3.5) in a greater proportion than that received by any
other Lender, such Lender agrees, promptly upon demand, to purchase a portion of
the Loans held by the other Lenders so that after such purchase each Lender will
hold its ratable proportion of Loans. If any Lender, whether in connection with
setoff or amounts which might be subject to setoff or otherwise, receives
collateral or other protection for its Obligations or such amounts which may be
subject to setoff, such Lender agrees, promptly upon demand, to take such action
necessary such that all Lenders share in the benefits of such collateral ratably
in proportion to their Loans. In case any such payment is disturbed by legal
process, or otherwise, appropriate further adjustments shall be made.

                                   ARTICLE XII

                BENEFIT OF AGREEMENT; ASSIGNMENTS; PARTICIPATIONS

         12.1. Successors and Assigns. The terms and provisions of the Loan
Documents shall be binding upon and inure to the benefit of the Borrower and the
Lenders and their respective successors and assigns, except that (a) the
Borrower shall not have the right to assign its rights or obligations under the
Loan Documents and (b) any assignment by any Lender must be made in compliance
with Section 12.3. Notwithstanding clause (b) of this Section, any Lender may at
any time, without the consent of the Borrower or the Agent, assign all or any
portion of its rights under this Agreement and any Note to a Federal Reserve
Bank; provided, however, that no such assignment to a Federal Reserve Bank shall
release the transferor Lender from its obligations hereunder. The Agent may
treat the Person which made any Loan or which holds any Note as the owner
thereof for all purposes hereof unless and until such Person complies with
Section 12.3 in the case of an assignment thereof or, in the case of any other
transfer, a written notice of the transfer is filed with the Agent. Any assignee
or transferee of the rights to any Loan or any Note agrees by acceptance of such
transfer or assignment to be bound by all the terms and provisions of the Loan
Documents. Any request, authority or consent of any Person, who at the time of
making such request or giving such authority or consent is the owner of the
rights to any Loan (whether or not a Note has been issued in evidence thereof),
shall be conclusive and binding on any subsequent holder, transferee or assignee
of the rights to such Loan.

         12.2.    Participations.

                  12.2.1 Permitted Participants; Effect. Any Lender may, in the
         ordinary course of its business and in accordance with applicable law,
         at any time sell to one or more banks or other entities
         ("Participants") participating interests in any Loan owing to such
         Lender, any Note held by such Lender, any Commitment of such Lender or
         any other interest of such


                                      -58-
<PAGE>   66

         Lender under the Loan Documents. In the event of any such sale by a
         Lender of participating interests to a Participant, such Lender's
         obligations under the Loan Documents shall remain unchanged, such
         Lender shall remain solely responsible to the other parties hereto for
         the performance of such obligations, such Lender shall remain the owner
         of its Loans and the holder of any Note issued to it in evidence
         thereof for all purposes under the Loan Documents, all amounts payable
         by the Borrower under this Agreement shall be determined as if such
         Lender had not sold such participating interests, and the Borrower and
         the Agent shall continue to deal solely and directly with such Lender
         in connection with such Lender's rights and obligations under the Loan
         Documents.

                  12.2.2. Voting Rights. Each Lender shall retain the sole right
         to approve, without the consent of any Participant, any amendment,
         modification or waiver of any provision of the Loan Documents other
         than any amendment, modification or waiver with respect to any Loan or
         Commitment in which such Participant has an interest which forgives
         principal, interest or fees or reduces the interest rate or fees
         payable with respect to any such Loan or Commitment, extends the
         Facility Termination Date, postpones any date fixed for any
         regularly-scheduled payment of principal of, or interest or fees on,
         any such Loan or Commitment, releases any guarantor of any such Loan or
         releases all or substantially all of the collateral, if any, securing
         any such Loan.

                  12.2.3. Benefit of Setoff. The Borrower agrees that each
         Participant shall be deemed to have the right of setoff provided in
         Section 11.1 in respect of its participating interest in amounts owing
         under the Loan Documents to the same extent as if the amount of its
         participating interest were owing directly to it as a Lender under the
         Loan Documents, provided that each Lender shall retain the right of
         setoff provided in Section 11.1 with respect to the amount of
         participating interests sold to each Participant. The Lenders agree to
         share with each Participant, and each Participant, by exercising the
         right of setoff provided in Section 11.1, agrees to share with each
         Lender, any amount received pursuant to the exercise of its right of
         setoff, such amounts to be shared in accordance with Section 11.2 as if
         each Participant were a Lender.

         12.3. Assignments.

                  12.3.1. Permitted Assignments. Any Lender may, in the ordinary
         course of its business and in accordance with applicable law, at any
         time assign to one or more banks or other entities ("Purchasers") all
         or any part of its rights and obligations under the Loan Documents.
         Such assignment shall be substantially in the form of Exhibit C or in
         such other form as may be agreed to by the parties thereto. The consent
         of the Borrower and the Agent shall be required prior to an assignment
         becoming effective with respect to a Purchaser which is not a Lender or
         an Affiliate thereof; provided, however, that if a Default has occurred
         and is continuing, the consent of the Borrower shall not be required.
         Such consent shall not be unreasonably withheld or delayed. Each such
         assignment shall (unless each of the Borrower and the Agent otherwise
         consents) (a) be in an amount not less than the lesser of (i)
         $10,000,000 (provided, however, that such amount shall be reduced
         dollar for dollar by the amount being simultaneously assigned under the
         Other Credit Agreement pursuant


                                      -59-
<PAGE>   67

         to subsection (b) of this sentence) or (ii) the remaining amount of the
         assigning Lender's Commitment (calculated as at the date of such
         assignment) and (b) assign a like percentage of such Lender's Other
         Loans and Commitment (as defined in the Other Credit Agreement) under
         the Other Credit Agreement.

                  12.3.2. Effect; Effective Date. Upon (a) delivery to the Agent
         of a notice of assignment, substantially in the form attached as
         Exhibit I to Exhibit C (a "Notice of Assignment"), together with any
         consents required by Section 12.3.1, and (b) payment of a $3,500 fee to
         the Agent for processing such assignment, such assignment shall become
         effective on the effective date specified in such Notice of Assignment.
         The Notice of Assignment shall contain a representation by the
         Purchaser to the effect that none of the consideration used to make the
         purchase of the Commitment and Loans under the applicable assignment
         agreement are "plan assets" as defined under ERISA and that the rights
         and interests of the Purchaser in and under the Loan Documents will not
         be "plan assets" under ERISA. On and after the effective date of such
         assignment, such Purchaser shall for all purposes be a Lender party to
         this Agreement and any other Loan Document executed by or on behalf of
         the Lenders and shall have all the rights and obligations of a Lender
         under the Loan Documents, to the same extent as if it were an original
         party hereto, and no further consent or action by the Borrower, the
         Lenders or the Agent shall be required to release the transferor Lender
         with respect to the percentage of the Aggregate Commitment and Loans
         assigned to such Purchaser. Upon the consummation of any assignment to
         a Purchaser pursuant to this Section 12.3.2, the transferor Lender, the
         Agent and the Borrower shall, if the transferor Lender or the Purchaser
         desires that its Loans be evidenced by Notes, make appropriate
         arrangements so that new Notes or, as appropriate, replacement Notes
         are issued to such transferor Lender and new Notes or, as appropriate,
         replacement Notes, are issued to such Purchaser, in each case in
         principal amounts reflecting their respective Commitments, as adjusted
         pursuant to such assignment.

         12.4. Dissemination of Information. The Borrower authorizes each Lender
to disclose to any Participant or Purchaser or any other Person acquiring an
interest in the Loan Documents by operation of law (each a "Transferee") and any
prospective Transferee any and all information in such Lender's possession
concerning the creditworthiness of the Borrower and its Subsidiaries; provided
that each Transferee and prospective Transferee agrees to be bound by Section
9.11 of this Agreement.

         12.5. Tax Treatment. If any interest in any Loan Document is
transferred to any Transferee which is organized under the laws of any
jurisdiction other than the United States or any State thereof, the transferor
Lender shall cause such Transferee, concurrently with the effectiveness of such
transfer, to comply with the provisions of Section 3.5(d).

         For the purposes of this Schedule, the following terms have the
following meanings, subject to the final paragraph of this Schedule:

         "Level I Status" exists at any date if, on such date, the Borrower's
Moody's Rating is A3 or better or the Borrower's S&P Rating is A- or better.**

         "Level II Status" exists at any date if, on such date, (i) the Borrower
has not qualified for Level I Status and (ii) the Borrower's Moody's Rating is
Baa1 or better or the Borrower's S&P Rating is BBB+ or better.**

- --------

* "Utilization" means, for any day, a percentage equal to the aggregate
principal amount of Loans, Other Loans and Facility Letters of Credit
outstanding on the close of business (if a Business Day) on such day divided by
the sum on such day of the Aggregate Commitment and the "Aggregate Commitment"
under the Other Agreement.

** In the event that a split occurs between the two ratings, then the rating
corresponding to the higher of the two ratings shall apply. However, if the
split is greater than one level, then the pricing shall be based upon the rating
that is between the two ratings; if the split is greater than two levels, then
the pricing shall be based upon the rating one level above the lowest of the two
ratings. In the event that one of the ratings is BB+ or Ba1 or lower, then the
pricing shall be based upon the lowest of the two ratings.

<PAGE>   72

         "Level III Status" exists at any date if, on such date, (i) the
Borrower has not qualified for Level I Status or Level II Status and (ii) the
Borrower's Moody's Rating is Baa2 or better or the Borrower's S&P Rating is BBB
or better.**

         "Level IV Status" exists at any date if, on such date, (i) the Borrower
has not qualified for Level I Status, Level II Status or Level III Status and
(ii) the Borrower's Moody's Rating is Baa3 or better or the Borrower's S&P
Rating is BBB- or better.***

         "Level V Status" exists at any date if, on such date, the Borrower has
not qualified for Level I Status, Level II Status, Level III Status or Level IV
Status.***

         "Moody's Rating" means, at any time, the rating issued by Moody's and
then in effect with respect to the Borrower's senior unsecured long-term debt
securities without third-party credit enhancement.

         "S&P Rating" means, at any time, the rating issued by S&P and then in
effect with respect to the Borrower's senior unsecured long-term debt securities
without third-party credit enhancement.

         "Status" means either Level I Status, Level II Status, Level III
Status, Level IV Status or Level V Status.

         The Applicable Margin and Applicable Fee Rate shall be determined in
accordance with the foregoing table based on the Borrower's Status as determined
from its then-current Moody's and S&P Ratings. The credit rating in effect on
any date for the purposes of this Schedule is that in effect at the close of
business on such date. If at any time the Borrower has no Moody's Rating or no
S&P Rating, Level IV Status shall exist.

         Notwithstanding the foregoing, the Borrower's Status shall be fixed at
Level III from the initial Borrowing Date until and including June 30, 1999.

- --------

*** In the event that a split occurs between the two ratings, then the rating
corresponding to the higher of the two ratings shall apply. However, if the
split is greater than one level, then the pricing shall be based upon the rating
that is between the two ratings; if the split is greater than two levels, then
the pricing shall be based upon the rating one level above the lowest of the two
ratings. In the event that one of the ratings is BB+ or Ba1 or lower, then the
pricing shall be based upon the lowest of the two ratings.

                                   ARTICLE II

                                   THE CREDITS

         2.1. Advances. (a) From and including the date hereof to but excluding
the Facility Termination Date, each Lender severally (and not jointly) agrees,
on the terms and conditions set forth in this Agreement, to make Loans to the
Borrower from time to time in amounts not to exceed in the aggregate at any one
time outstanding the amount of its pro-rata share of the Aggregate Commitment
existing at such time. Subject to the terms of this Agreement, the Borrower may
borrow, repay and reborrow Advances at any time prior to the Facility
Termination Date. The Commitments to lend shall expire on the Facility
Termination Date.

                    (b) The Borrower hereby agrees that, if at any time as a
result of reductions in the Aggregate Commitment pursuant to Section 2.4(b),
Section 2.7 or otherwise, the aggregate balance of the sum of the Loans exceeds
the Aggregate Commitment, the Borrower shall repay immediately its then
outstanding Loans in such amount as may be necessary to eliminate such excess.

                    (c) Any outstanding Advances and all other unpaid
Obligations shall be paid in full by the Borrower on the Facility Termination
Date.

         2.2. Ratable Loans. Each Advance hereunder shall consist of Loans made
from the several Lenders ratably in proportion to the ratio that their
respective Commitments bear to the Aggregate Commitment.

         2.3. Types of Advances. The Advances may be Alternate Base Rate
Advances or Eurodollar Advances, or a combination thereof, selected by the
Borrower in accordance with Sections 2.8 and 2.9.

         2.4. Facility and Utilization Fees; Reductions in Aggregate Commitment.
(a) The Borrower agrees to pay to the Agent for the account of each Lender a
facility fee at a per annum rate equal to the Applicable Facility Fee Rate on
the daily average Commitment of such Lender (regardless of usage) from the date
hereof to and including the Facility Termination Date, payable on each Payment
Date hereafter and on the Facility Termination Date. The Borrower also agrees to
pay to the Agent for the pro-rata account of the Lenders a utilization fee for
each day from the date hereof to and including the later of the Facility
Termination Date and the date all Loans are paid in full, such utilization fee
to be equal to the Applicable Utilization Fee Rate for such day multiplied by
the aggregate outstanding principal amount of the Loans on such day, payable on
each Payment Date and the Facility Termination Date.

<PAGE>   23
                    (b) The Borrower may permanently reduce the Aggregate
Commitment in whole, or in part ratably among the Lenders in a minimum aggregate
amount of $10,000,000 or any integral multiple of $5,000,000 in excess thereof,
upon at least five (5) Business Days' written notice to the Agent, which notice
shall specify the amount of any such reduction; provided, however, that the
amount of the Aggregate Commitment may not be reduced below the aggregate
principal amount of the outstanding Advances. All accrued facility and
utilization fees shall be payable on the effective date of any termination of
the obligations of the Lenders to make Loans hereunder.

         2.5. Minimum Amount of Each Advance. Each Eurodollar Advance shall be
in the minimum amount of $10,000,000 (and in multiples of $1,000,000 if in
excess thereof), and each Alternate Base Rate Advance shall be in the minimum
amount of $5,000,000 (and in multiples of $500,000 if in excess thereof);
provided, however, that (a) any Alternate Base Rate Advance may be in the amount
of the unused Aggregate Commitment and (b) in no event shall more than six (6)
Eurodollar Advances be permitted to be outstanding at any time.

         2.6. Optional Principal Payments. The Borrower may from time to time
pay, without penalty or premium, all outstanding Alternate Base Rate Advances,
or, in a minimum aggregate amount of $5,000,000 or any integral multiple of
$500,000 in excess thereof, any portion of the outstanding Alternate Base Rate
Advances upon notice to the Agent prior to 10:00 a.m. (Chicago time) on the date
of such prepayment. The Borrower may from time to time pay, subject to the
payment of any funding indemnification amounts required by Section 3.4 but
without penalty or premium, all outstanding Eurodollar Advances, or, in a
minimum aggregate amount of $10,000,000 or any integral multiple of $1,000,000
in excess thereof, any portion of the outstanding Eurodollar Advances upon three
(3) Business Days' prior notice to the Agent.

         2.7. Mandatory Commitment Reductions.

                    (a) The Aggregate Commitment shall be automatically and
permanently reduced in the amounts and at the times set forth below:

                           (i) concurrently with the receipt thereof by the
         Borrower or any Subsidiary, 100% of the aggregate Net Available
         Proceeds realized upon the Scheduled Asset Sale; provided that such
         reduction shall be required only to the extent needed to reduce the
         Aggregate Commitment to $100,000,000; and

                           (ii) concurrently with the receipt thereof by the
         Borrower or any Subsidiary, 100% of the Net Available Proceeds realized
         upon the sale, issuance or incurrence of indebtedness for money
         borrowed (exclusive of any Loan or Other Loan) having a final maturity
         of greater than one year by the Borrower or such Subsidiary; provided
         that such reduction shall be required only to the extent needed to
         reduce the Aggregate Commitment to $100,000,000.

                    (b) Contemporaneously with any automatic reductions in the
Aggregate Commitment pursuant to Section 2.7(a), the Borrower shall prepay the
Loans in an amount equal to the lesser of (A) the outstanding principal amount
of Loans and (B) the amount of such reduction;



                                      -16-
<PAGE>   24
provided, however, that no such prepayment shall be required if, at such time,
the Borrower could satisfy the conditions set forth in Section 4.2(b) for the
reborrowing thereof. The preceding sentence shall not affect the obligations of
the Borrower under Section 2.1(b).

                    (c) Mandatory commitment reductions under this Section 2.7
shall be cumulative and in addition to reductions occurring pursuant to Section
2.4(b).

                    (d) Any reduction in the Aggregate Commitment pursuant to
this Section 2.7 or otherwise shall ratably reduce the Commitment of each
Lender.

         2.8. Method of Selecting Types and Interest Periods for New Advances.
The Borrower shall select the Type of Advance and, in the case of each
Eurodollar Advance, the Interest Period applicable thereto from time to time.
The Borrower shall give the Agent irrevocable notice (a "Borrowing Notice") not
later than 10:00 a.m. (Chicago time) at least one (1) Business Day before the
Borrowing Date of each Alternate Base Rate Advance and at least three (3)
Business Days before the Borrowing Date for each Eurodollar Advance, specifying:

                    (a) the Borrowing Date of such Advance, which shall be a
Business Day;

                    (b) the aggregate amount of such Advance;

                    (c) the Type of Advance selected; and

                    (d) in the case of each Eurodollar Advance, the Interest
Period applicable thereto, which shall end on or prior to the Facility
Termination Date.

Not later than noon (Chicago time) on each Borrowing Date, each Lender shall
make available its Loan or Loans in funds immediately available in Chicago to
the Agent at its address specified pursuant to Article XIII. The Agent will make
the funds so received from the Lenders available to the Borrower at the Agent's
aforesaid address.

         2.9. Conversion and Continuation of Outstanding Advances. Alternate
Base Rate Advances shall continue as Alternate Base Rate Advances unless and
until such Alternate Base Rate Advances are converted into Eurodollar Advances
pursuant to this Section 2.9 or are repaid in accordance with Section 2.6. Each
Eurodollar Advance shall continue as a Eurodollar Advance until the end of the
then applicable Interest Period therefor, at which time such Eurodollar Advance
shall be automatically converted into a Alternate Base Rate Advance unless (x)
such Eurodollar Advance is or was repaid in accordance with Section 2.6 or (y)
the Borrower shall have given the Agent a Conversion/Continuation Notice (as
defined below) requesting that, at the end of such Interest Period, such
Eurodollar Advance continue as a Eurodollar Advance for the same or another
Interest Period. Subject to the terms of Section 2.5, the Borrower may elect
from time to time to convert all or any part of a Alternate Base Rate Advance
into a Eurodollar Advance. The Borrower shall give the Agent irrevocable notice
(a "Conversion/Continuation Notice") of each conversion of a Alternate Base Rate
Advance into a Eurodollar Advance or continuation of a Eurodollar Advance not
later



                                      -17-
<PAGE>   25
than 10:00 a.m. (Chicago time) at least three (3) Business Days prior to the
date of the requested conversion or continuation, specifying:

      (i)     the requested date, which shall be a Business Day, of such
              conversion or continuation,

     (ii)     the aggregate amount and Type of the Advance which is to be
              converted or continued, and

    (iii)     the amount of such Advance which is to be converted into or
              continued as a Eurodollar Advance and the duration of the Interest
              Period applicable thereto.

         2.10. Changes in Interest Rate, etc. Each Alternate Base Rate Advance
shall bear interest on the outstanding principal amount thereof, for each day
from and including the date such Advance is made or is automatically converted
from a Eurodollar Advance into a Alternate Base Rate Advance pursuant to Section
2.9, to but excluding the date it is paid or is converted into a Eurodollar
Advance pursuant to Section 2.9 hereof, at a rate per annum equal to the
Alternate Base Rate for such day. Changes in the rate of interest on that
portion of any Advance maintained as a Alternate Base Rate Advance will take
effect simultaneously with each change in the Alternate Base Rate. Each
Eurodollar Advance shall bear interest on the outstanding principal amount
thereof from and including the first day of the Interest Period applicable
thereto to (but not including) the last day of such Interest Period at the
interest rate determined by the Agent as applicable to such Eurodollar Advance
based upon the Borrower's selections under Section 2.8 and 2.9 and otherwise in
accordance with the terms hereof. No Interest Period may end after the Facility
Termination Date.

         2.11. Rates Applicable After Default. Notwithstanding anything to the
contrary contained in Section 2.8 or 2.9, during the continuance of a Default or
Unmatured Default the Required Lenders may, at their option, by notice to the
Borrower (which notice may be revoked at the option of the Required Lenders
notwithstanding any provision of Section 8.2 requiring unanimous consent of the
Lenders to changes in interest rates), declare that no Advance may be made as,
converted into or continued as a Eurodollar Advance. During the continuance of a
Default under Section 7.2, 7.6 or 7.7, without any election or action on the
part of the Agent or any Lender, (i) each Eurodollar Advance shall bear interest
for the remainder of the applicable Interest Period at the rate otherwise
applicable to such Interest Period plus 2% per annum and (ii) each Alternate
Base Rate Advance shall bear interest at a rate per annum equal to the Alternate
Base Rate in effect from time to time plus 2% per annum.

         2.12. Method of Payment. All payments of the Obligations hereunder
shall be made, without setoff, deduction, or counterclaim, in immediately
available funds to the Agent at the Agent's address specified pursuant to
Article XIII, or at any other Lending Installation of the Agent specified in
writing by the Agent to the Borrower, by noon (Chicago time) on the date when
due and shall be applied ratably by the Agent among the Lenders. Each payment
delivered to the Agent for the account of any Lender shall be delivered promptly
by the Agent to such Lender in the same type of funds that the Agent received at
its address specified pursuant to Article XIII or at any Lending Installation
specified in a notice received by the Agent from such Lender. The Agent is
hereby



                                      -18-
<PAGE>   26
authorized to charge the account of the Borrower maintained with First Chicago
for each payment of principal, interest and fees as it becomes due hereunder.

         2.13. Noteless Agreement; Evidence of Indebtedness. (a) Each Lender
shall maintain in accordance with its usual practice an account or accounts
evidencing the indebtedness of the Borrower to such Lender resulting from each
Loan made by such Lender from time to time, including the amounts of principal
and interest payable and paid to such Lender from time to time hereunder.

                    (b) The Agent shall also maintain accounts in which it will
record (i) the amount of each Loan made hereunder, the Type thereof and the
Interest Period with respect thereto, (ii) the amount of any principal or
interest due and payable or to become due and payable from the Borrower to each
Lender hereunder and (iii) the amount of any sum received by the Agent hereunder
from the Borrower and each Lender's share thereof.

                    (c) The entries maintained in the accounts maintained
pursuant to paragraphs (a) and (b) above shall be prima facie evidence of the
existence and amounts of the Obligations therein recorded; provided, however,
that in the event of a conflict between the accounts maintained pursuant to
paragraphs (a) and (b) above, the accounts maintained pursuant to paragraph (a)
above shall be presumed to be correct absent demonstrable error, provided,
further, that the failure of the Agent or any Lender to maintain such accounts
or any error therein shall not in any manner affect the obligation of the
Borrower to repay the Obligations in accordance with their terms.

                    (d) Any Lender may request that its Loans be evidenced by a
promissory note (a "Note"). In such event, the Borrower shall prepare, execute
and deliver to such Lender a Note payable to the order of such Lender in a form
supplied by the Agent. Thereafter, the Loans evidenced by such Note and interest
thereon shall at all times (including after any assignment pursuant to Section
12.3) be represented by one or more Notes payable to the order of the payee
named therein or any assignee pursuant to Section 12.3, except to the extent
that any such Lender or assignee subsequently returns any such Note for
cancellation and requests that such Loans once again be evidenced as described
in paragraphs (a) and (b) above.

         2.14. Telephonic Notices. The Borrower hereby authorizes the Lenders
and the Agent to extend, convert or continue Advances, effect selections of
Types of Advances and to transfer funds based on telephonic notices made by any
person or persons the Agent or any Lender in good faith believes to be an
Authorized Officer or other person previously authorized in writing by the
Borrower to take such actions on behalf of the Borrower. The Borrower agrees to
deliver promptly to the Agent a written confirmation, if such confirmation is
requested by the Agent or any Lender, of each telephonic notice signed by an
Authorized Officer. If the written confirmation differs in any material respect
from the action taken by the Agent and the Lenders, the records of the Agent and
the Lenders shall govern absent manifest error.

         2.15. Interest Payment Dates; Interest and Fee Basis. Interest accrued
on each Alternate Base Rate Advance shall be payable on each Payment Date,
commencing with the first such date to occur after the date hereof and at
maturity. Interest accrued on each Eurodollar Advance shall



                                      -19-
<PAGE>   27
be payable on the last day of its applicable Interest Period, on any date on
which the Eurodollar Advance is prepaid, whether by acceleration or otherwise,
and at maturity. Interest accrued on each Eurodollar Advance having an Interest
Period longer than three months shall also be payable on the last day of each
three-month interval during such Interest Period. Interest shall be calculated
for actual days elapsed on the basis of a 365 (or 366, as applicable) day year
with respect to Alternate Base Rate Advances. Interest with respect to
Eurodollar Advances and fees shall be calculated for actual days elapsed on the
basis of a 360-day year. Interest shall be payable for the day an Advance is
made but not for the day of any payment on the amount paid if payment is
received prior to noon (Chicago time) at the place of payment. If any payment of
principal of or interest on an Advance shall become due on a day which is not a
Business Day, such payment shall be made on the next succeeding Business Day
and, in the case of a principal payment, such extension of time shall be
included in computing interest in connection with such payment.

         2.16. Notification of Advances, Interest Rates, Prepayments and
Commitment Reductions. Promptly after receipt thereof, the Agent will notify
each Lender of the contents of each Aggregate Commitment reduction notice,
Borrowing Notice, Conversion/Continuation Notice and repayment notice received
by it hereunder. The Agent will notify each Lender of the interest rate
applicable to each Eurodollar Advance promptly upon determination of such
interest rate and will give each Lender prompt notice of each change in the
Alternate Base Rate.

         2.17. Lending Installations. Each Lender may book its Loans at any
Lending Installation selected by such Lender and may change its Lending
Installation from time to time. All terms of this Agreement shall apply to any
such Lending Installation and the Loans and any Notes issued hereunder shall be
deemed held by each Lender for the benefit of such Lending Installation. Each
Lender may, by written notice to the Agent and the Borrower in accordance with
Article XIII, designate replacement or additional Lending Installations through
which Loans will be made by it and for whose account Loan payments are to be
made.

         2.18. Non-Receipt of Funds by the Agent. Unless the Borrower or a
Lender, as the case may be, notifies the Agent prior to the date on which it is
scheduled to make payment to the Agent of (a) in the case of a Lender, the
proceeds of a Loan or (b) in the case of the Borrower, a payment of principal,
interest or fees to the Agent for the account of the Lenders, that it does not
intend to make such payment, the Agent may assume that such payment has been
made. The Agent may, but shall not be obligated to, make the amount of such
payment available to the intended recipient in reliance upon such assumption. If
such Lender or the Borrower, as the case may be, has not in fact made such
payment to the Agent, the recipient of such payment shall, on demand by the
Agent, repay to the Agent the amount so made available together with interest
thereon in respect of each day during the period commencing on the date such
amount was so made available by the Agent until the date the Agent recovers such
amount at a rate per annum equal to (x) in the case of payment by a Lender, the
Federal Funds Effective Rate for such day or (y) in the case of payment by the
Borrower, the interest rate applicable to the relevant Loan.

         2.19. Intentionally Omitted.

         2.20. Extension of Facility Termination Date. The Borrower may request
an extension of the Facility Termination Date by submitting a request for an
extension to the Agent (an "Extension Request") no more than sixty (60) days
prior to each anniversary of the date hereof. The Extension Request must specify
the new Facility Termination Date requested by the Borrower and the date (which
must be at least thirty (30) days after the Extension Request is delivered to
the Agent) as of which the Lenders must respond to the Extension Request (the
"Response Date"). The new Facility Termination Date shall be the date three
hundred and sixty four (364) days after the Facility Termination Date in effect
at the time the Extension Request is received. Promptly upon receipt of an
Extension Request, the Agent shall notify each Lender of the contents thereof
and shall request each Lender to approve the Extension Request. Each Lender,
acting in its sole discretion, may approve or decline to approve such Extension
Request. Each Lender approving the Extension Request shall deliver its written
consent no later than the Response Date. If and only if the written consent of
each of the Lenders is received by the Agent prior to the then effective
Facility Termination Date, the Facility Termination Date specified in the
Extension Request shall become effective on the existing Facility Termination
Date and the Agent shall promptly notify the Borrower and each Lender of the new
Facility Termination Date.

                             YIELD PROTECTION; TAXES


         3.1. Yield Protection. If, on or after the date of this Agreement, the
adoption of any law or any governmental or quasi-governmental rule, regulation,
policy, guideline or directive (whether or not having the force of law), or any
change in the interpretation or administration thereof by any governmental or
quasi-governmental authority, central bank or comparable agency charged with the
interpretation or administration thereof, or compliance by any Lender or
applicable Lending Installation with any request or directive (whether or not
having the force of law) of any such authority, central bank or comparable
agency:

         (a)      subjects any Lender or any applicable Lending Installation to
                  any Taxes, or changes the basis of taxation of payments (other
                  than with respect to Excluded Taxes) to any Lender in respect
                  of its Eurodollar Loans, or

         (b)      imposes or increases or deems applicable any reserve,
                  assessment, insurance charge, special deposit or similar
                  requirement against assets of, deposits with or for the
                  account of, or credit extended by, any Lender or any
                  applicable Lending Installation (other than reserves and
                  assessments taken into account in determining the interest
                  rate applicable to Eurodollar Advances), or

         (c)      imposes any other condition the result of which is to increase
                  the cost to any Lender or any applicable Lending Installation
                  of making, funding or maintaining



                                      -21-
<PAGE>   29
                  its Eurodollar Loans or reduces any amount receivable by any
                  Lender or any applicable Lending Installation in connection
                  with its Eurodollar Loans, or requires any Lender or any
                  applicable Lending Installation to make any payment calculated
                  by reference to the amount of Eurodollar Loans held or
                  interest received by it, by an amount deemed material by such
                  Lender,

and the result of any of the foregoing is to increase the cost to such Lender or
applicable Lending Installation of making or maintaining its Eurodollar Loans or
Commitment or to reduce the return received by such Lender or applicable Lending
Installation in connection with such Eurodollar Loans or Commitment in either
case by an amount which such Lender deems to be material, then, within fifteen
(15) days of demand by such Lender, the Borrower shall pay such Lender such
additional amount or amounts as will compensate such Lender for such increased
cost or reduction in amount received.

         3.2. Changes in Capital Adequacy Regulations. If a Lender determines
the amount of capital required or expected to be maintained by such Lender, any
applicable Lending Installation of such Lender or any corporation controlling
such Lender is increased as a result of a Change, then, within fifteen (15) days
of demand by such Lender, the Borrower shall pay such Lender the amount
necessary to compensate for any shortfall in the rate of return on the portion
of such increased capital which such Lender determines is attributable to this
Agreement, its Loans or its Commitment to make Loans hereunder (after taking
into account such Lender's policies as to capital adequacy). "Change" means (i)
any change after the date of this Agreement in the Risk-Based Capital Guidelines
or (ii) any adoption of or change in any other law, governmental or
quasi-governmental rule, regulation, policy, guideline, interpretation, or
directive (whether or not having the force of law) after the date of this
Agreement which affects the amount of capital required or expected to be
maintained by any Lender or any Lending Installation or any corporation
controlling any Lender. "Risk-Based Capital Guidelines" means (i) the risk-based
capital guidelines in effect in the United States on the date of this Agreement,
including transition rules, and (ii) the corresponding capital regulations
promulgated by regulatory authorities outside the United States implementing the
July 1988 report of the Basle Committee on Banking Regulation and Supervisory
Practices Entitled "International Convergence of Capital Measurements and
Capital Standards," including transition rules, and any amendments to such
regulations adopted prior to the date of this Agreement.

         3.3. Availability of Types of Advances. If (a) any Lender determines
that maintenance of its Eurodollar Loans at a suitable Lending Installation
would violate any applicable law, rule, regulation, or directive, whether or not
having the force of law and gives notice of such determination to the Borrower
and the Agent, or (b) if the Required Lenders determine that (i) deposits of a
type and maturity appropriate to match fund Eurodollar Advances are not
available or (ii) the interest rate applicable to a Type of Advance does not
accurately reflect the cost of making or maintaining such Advance, then the
Agent shall suspend the availability of the affected Type of Advance from the
affected Lender, in the case of any occurrence set forth in clause (a), or from
all Lenders, in the case of any occurrence set forth in clause (b), and, in the
case of any occurrence set forth in clause (a), require any affected Eurodollar
Advances to be repaid or converted to Alternate Base Rate Advances, subject to
the payment of any funding indemnification amounts required by Section 3.4.
Until the Lender giving the notice in (a) above has either rescinded such notice
or been



                                      -22-
<PAGE>   30
replaced pursuant to Section 3.7, any Eurodollar Loan which would otherwise have
been required to be made by such Lender shall be made as an Alternate Base Rate
Advance.

         3.4. Funding Indemnification. If any payment of a Eurodollar Advance
occurs on a date which is not the last day of the applicable Interest Period,
whether because of acceleration, prepayment or otherwise, or a Eurodollar
Advance is not made on the date specified by the Borrower for any reason other
than default by any Lender, the Borrower will indemnify each Lender for any loss
or cost incurred by it resulting therefrom, including, without limitation, any
loss or cost in liquidating or employing deposits acquired to fund or maintain
such Eurodollar Advance.

         3.5. Taxes. (a) All payments by the Borrower to or for the account of
any Lender or the Agent hereunder or under any Note shall be made free and clear
of and without deduction for any and all Taxes. If the Borrower shall be
required by law to deduct any Taxes from or in respect of any sum payable
hereunder to any Lender or the Agent, (i) the sum payable shall be increased as
necessary so that after making all required deductions (including deductions
applicable to additional sums payable under this Section 3.5) such Lender or the
Agent (as the case may be) receives an amount equal to the sum it would have
received had no such deductions been made, (ii) the Borrower shall make such
deductions, (iii) the Borrower shall pay the full amount deducted to the
relevant authority in accordance with applicable law and (iv) the Borrower shall
furnish to the Agent the original copy of any receipt obtained by the Borrower
evidencing payment thereof within thirty (30) days after such receipt is
obtained.

         (b) In addition, the Borrower hereby agrees to pay any present or
future stamp or documentary taxes and any other excise or property taxes,
charges or similar levies which arise from any payment made hereunder or under
any Note or from the execution or delivery of, or otherwise with respect to,
this Agreement or any Note ("Other Taxes").

         (c) The Borrower hereby agrees to indemnify the Agent and each Lender
for the full amount of Taxes or Other Taxes (including, without limitation, any
Taxes or Other Taxes imposed on amounts payable under this Section 3.5) paid by
the Agent or such Lender and any liability (including penalties, interest and
expenses) arising therefrom or with respect thereto. Payments due under this
indemnification shall be made within thirty (30) days of the date the Agent or
such Lender makes demand therefor pursuant to Section 3.6.

         (d) Each Lender that is not incorporated under the laws of the United
States of America or a state thereof (each a "Non-U.S. Lender") agrees that it
will, not less than ten (10) Business Days after the date of this Agreement or,
if later, the date such Lender becomes a party hereto pursuant to Section 12.3,
(i) deliver to each of the Borrower and the Agent two duly completed copies of
United States Internal Revenue Service Form 1001 or 4224, certifying in either
case that such Lender is entitled to receive payments under this Agreement
without deduction or withholding of any United States federal income taxes, and
(ii) deliver to each of the Borrower and the Agent a United States Internal
Revenue Form W-8 or W-9, as the case may be, and certify that it is entitled to
an exemption from United States backup withholding tax. Each Non-U.S. Lender
further undertakes to deliver to each of the Borrower and the Agent (x) renewals
or additional copies of such form (or any successor form) on or before the date
that such form expires or becomes obsolete,



                                      -23-
<PAGE>   31
and (y) after the occurrence of any event requiring a change in the most recent
forms so delivered by it, such additional forms or amendments thereto as may be
reasonably requested by the Borrower or the Agent. All forms or amendments
described in the preceding sentence shall certify that such Lender is entitled
to receive payments under this Agreement without deduction or withholding of any
United States federal income taxes, unless an event (including without
limitation any change in treaty, law or regulation) has occurred prior to the
date on which any such delivery would otherwise be required which renders all
such forms inapplicable or which would prevent such Lender from duly completing
and delivering any such form or amendment with respect to it and such Lender
advises the Borrower and the Agent that it is not capable of receiving payments
without any deduction or withholding of United States federal income tax.

         (e) For any period during which a Non-U.S. Lender has failed to provide
the Borrower with an appropriate form pursuant to clause (d) above (unless such
failure is due to a change in treaty, law or regulation, or any change in the
interpretation or administration thereof by any governmental authority,
occurring subsequent to the date on which a form originally was required to be
provided), such Non-U.S. Lender shall not be entitled to indemnification under
this Section 3.5 with respect to Taxes imposed by the United States; provided
that, should a Non-U.S. Lender which is otherwise exempt from or subject to a
reduced rate of withholding tax become subject to Taxes because of its failure
to deliver a form required under clause (d), above, the Borrower shall take such
steps as such Non-U.S. Lender shall reasonably request to assist such Non-U.S.
Lender to recover such Taxes.

         (f) Any Lender that is entitled to an exemption from or reduction of
withholding tax with respect to payments under this Agreement or any Note
pursuant to the law of any relevant jurisdiction or any treaty shall deliver to
the Borrower (with a copy to the Agent), at the time or times prescribed by
applicable law, such properly completed and executed documentation prescribed by
applicable law as will permit such payments to be made without withholding or at
a reduced rate.

         3.6. Lender Statements; Survival of Indemnity. To the extent reasonably
possible, each Lender shall designate an alternate Lending Installation with
respect to its Eurodollar Loans to reduce any liability of the Borrower to such
Lender under Sections 3.1, 3.2 and 3.5 or to avoid the unavailability of
Eurodollar Advances under Section 3.3, so long as such designation is not, in
the reasonable judgment of such Lender, disadvantageous to such Lender. Each
Lender shall deliver a written statement of such Lender to the Borrower (with a
copy to the Agent) as to the amount due, if any, under Section 3.1, 3.2, 3.4 or
3.5. Such written statement shall set forth in reasonable detail the
calculations upon which such Lender determined such amount and shall be final,
conclusive and binding on the Borrower in the absence of manifest error.
Determination of amounts payable under such Sections in connection with a
Eurodollar Loan shall be calculated as though each Lender funded its Eurodollar
Loan through the purchase of a deposit of the type and maturity corresponding to
the deposit used as a reference in determining the Eurodollar Rate applicable to
such Loan, whether in fact that is the case or not. Unless otherwise provided
herein, the amount specified in the written statement of any Lender shall be
payable on demand after receipt by the Borrower of such written statement. The
obligations of the Borrower under Sections 3.1, 3.2, 3.4 and 3.5 shall survive
payment of the Obligations and termination of this Agreement.




                                      -24-
<PAGE>   32
         3.7. Substitution of Lenders. Any Lender (a) claiming any additional
amounts payable pursuant to Section 3.1, 3.2, or 3.5, (b) which gives a notice
described in Section 3.3, or (c) declining to approve of an Extension Request
pursuant to Section 2.20, shall, so long as no Default or Unmatured Default has
occurred and is continuing, upon the written request of the Borrower delivered
to such Lender and the Agent, assign, pursuant to and in accordance with the
provisions of Section 12.3, all of its rights and obligations under this
Agreement and under the Loan Documents to another Lender or to a commercial
bank, other financial institution, commercial finance company or other business
lender selected by the Borrower and reasonably acceptable to the Agent that (a)
has agreed not to claim any additional amounts under Section 3.1, 3.2 or 3.5
with respect to some or all of the costs or regulatory charges that gave rise to
such assigning Lender's claim for such compensation, (b) has not made a
determination of the type described in Section 3.3, or (c) has not declined to
approve of an Extension Request pursuant to Section 2.20, as applicable, in
consideration for (a) the payment by such assignee to such assigning Lender of
the principal of, and interest accrued and unpaid to the date of such assignment
on, the Loans held by such assigning Lender, (b) the payment by the Borrower to
such assigning Lender of any and all other amounts owing to such assigning
Lender under any provision of this Agreement accrued and unpaid to the date of
such assignment and (c) the payment by the Borrower to such assigning Lender of
any amounts which would be payable to such Lender pursuant to Section 3.4 were
such assignment treated as a repayment of such Loans.

                                    ARTICLE V

                         REPRESENTATIONS AND WARRANTIES

         The Borrower represents and warrants to the Lenders that, both before
and after giving effect to the Closing Transactions:

         5.1. Existence and Standing. Each of the Borrower and its Subsidiaries
is a corporation, partnership (in the case of Subsidiaries only) or limited
liability company (in the case of Subsidiaries only) duly and properly
incorporated or organized, as the case may be, validly existing and (to the
extent such concept applies to such entity) in good standing under the laws of
its jurisdiction of incorporation or organization and has all requisite
authority to conduct its business in each jurisdiction in which its business is
conducted.

         5.2. Authorization and Validity. The Borrower and each Guarantor has
the power and authority and legal right to execute and deliver the Loan
Documents and other Transaction Documents to which it is a party and to perform
its obligations thereunder. The execution and delivery by the Borrower and each
Guarantor of the Loan Documents and other Transaction Documents to which it is a
party and the performance of its respective obligations thereunder have been
duly authorized by proper corporate proceedings, and the Loan Documents and
other Transaction Documents to which the Borrower or any Guarantor is a party
constitute legal, valid and binding obligations of the Borrower or such
Guarantor, as applicable, enforceable against the Borrower or such Guarantor, as
applicable, in accordance with their terms, except as enforceability may be
limited by bankruptcy, insolvency or similar laws affecting the enforcement of
creditors' rights generally.

         5.3. No Conflict; Government Consent. Neither the execution and
delivery by the Borrower or any Guarantor of the Loan Documents and other
Transaction Documents to which it is a party, nor the consummation of the
transactions therein contemplated, nor compliance with the provisions thereof
will violate (i) any law, rule, regulation, order, writ, judgment, injunction,
decree or award binding on the Borrower or any of its Subsidiaries or (ii) the
Borrower's or any Subsidiary's articles or certificate of incorporation,
partnership agreement, certificate of partnership, articles or certificate of
organization, by-laws, or operating or other management agreement, as the case
may be, or (iii) the provisions of any indenture, instrument or agreement to
which the Borrower or any of its Subsidiaries is a party or is subject, or by
which it, or its Property, is bound, or conflict with or constitute a default
thereunder, or result in, or require, the creation or imposition of any Lien in,
of or on the Property of the Borrower or a Subsidiary pursuant to the terms of
any such indenture, instrument or agreement. No order, consent, adjudication,
approval, license, authorization, or validation of, or filing, recording or
registration with, or exemption by, or other action in respect of any
governmental or public body or authority, or any subdivision thereof, which has
not been obtained by the Borrower or any of its Subsidiaries, is required to be
obtained by the Borrower or any of its Subsidiaries in connection with the
execution and delivery of the Loan Documents and other Transaction Documents,
the borrowings under this Agreement, the payment and performance by the Borrower
of the Obligations or the legality, validity, binding effect or enforceability
of any of the Loan Documents. Neither the Borrower nor any Subsidiary is in
default under or in violation



                                      -30-
<PAGE>   38
of any foreign, federal, state or local law, rule, regulation, order, writ,
judgment, injunction, decree or award binding upon or applicable to the Borrower
or such Subsidiary, in each case the consequences of which default or violation
could reasonably be expected to have a Material Adverse Effect.

         5.4. Financial Statements. The December 31, 1997 audited consolidated
financial statements and the June 30, 1998 unaudited consolidated financial
statements of (a) the Borrower and its Subsidiaries and (b) LTI and its
Subsidiaries heretofore delivered to the Lenders were prepared in accordance
with generally accepted accounting principles in effect on the date such
statements were prepared and fairly present in all material respects the
consolidated financial condition and results of operations of the Borrower and
its Subsidiaries or LTI and its Subsidiaries, as applicable at such date and the
consolidated results of their operations for the periods then ended. The pro
forma balance sheet and related profit and loss statement (the "Pro Forma") of
the Borrower and its Subsidiaries on a consolidated basis as of September 30,
1998 is attached hereto as Schedule 5.4. As of the date of this Agreement, the
Pro Forma is complete and accurate and fairly represents in all material
respects the Borrower's and the Subsidiaries' assets, liabilities, financial
condition and results of operations on a consolidated basis in accordance with
Agreement Accounting Principles, consistently applied, and taking into account
the Closing Transactions, the consummation of the Merger and the other
transactions and actions contemplated by this Agreement, the Loan Documents and
the Transaction Documents.

         5.5. Material Adverse Change. Since June 30, 1998 there has been no
change in the business, Property, financial condition or results of operations
of the Borrower and its Subsidiaries which could reasonably be expected to have
a Material Adverse Effect.

         5.6. Taxes. The Borrower and its Subsidiaries have filed all United
States federal tax returns and all other tax returns which are required to be
filed and have paid all taxes shown to be due pursuant to said returns or
pursuant to any assessment received by the Borrower or any of its Subsidiaries,
except such taxes, if any, the non-payment of which could not reasonably be
expected to have a Material Adverse Effect. As of the date hereof, the United
States income tax returns of the Borrower and its Subsidiaries have been audited
by the Internal Revenue Service through the Fiscal Year ended December 31, 1993
and those of LTI have been audited through the Fiscal Year ended December 31,
1989. No tax liens have been filed and no claims are being asserted with respect
to any such taxes. The charges, accruals and reserves on the books of the
Borrower and its Subsidiaries in respect of any taxes or other governmental
charges are adequate.

         5.7. Litigation and Contingent Obligations. There is no litigation,
arbitration, governmental investigation, proceeding or inquiry pending or, to
the knowledge of any of their officers, threatened against or affecting the
Borrower or any of its Subsidiaries which could reasonably be expected to have a
Material Adverse Effect or which seeks to prevent, enjoin or delay the making of
any Loans. Other than any liability incident to any litigation, arbitration or
proceeding which could not reasonably be expected to have a Material Adverse
Effect, the Borrower has no material contingent obligations not provided for or
disclosed in the financial statements referred to in Section 5.4.

         5.8. Subsidiaries. Schedule 5.8 contains an accurate list of all
Subsidiaries of the Borrower as of the date of this Agreement, setting forth
their respective jurisdictions of organization and the percentage of their
respective capital stock or other ownership interests owned by the Borrower or
other Subsidiaries. All of the issued and outstanding shares of capital stock or
other ownership interests of such Subsidiaries have been (to the extent such
concepts are relevant with respect to such ownership interests) duly authorized
and issued and are fully paid and non-assessable.

         5.9. ERISA. The Unfunded Liabilities of all Single Employer Plans do
not in the aggregate exceed $5,000,000. Neither the Borrower nor any other
member of the Controlled Group has incurred, or is reasonably expected to incur,
any withdrawal liability to Multiemployer Plans. Each Plan complies in all
material respects with all applicable requirements of law and regulations, no
Reportable Event has occurred with respect to any Plan, neither the Borrower nor
any other member of the Controlled Group has withdrawn from any Plan or
initiated steps to do so, and no steps have been taken to reorganize or
terminate any Plan.

         5.10. Defaults. No Default or Unmatured Default has occurred and is
continuing.

         5.11. Regulation U. Margin stock (as defined in Regulation U)
constitutes less than 25% of the value of those assets of the Borrower and its
Subsidiaries which are subject to any limitation on sale, pledge, or other
restriction hereunder. Neither the making of any Advance, the use of the
proceeds thereof, nor any other aspect of the financing of the Acquisition, will
violate or be inconsistent with the provisions of Regulation T, Regulation U or
Regulation X.

         5.12. Material Agreements. Neither the Borrower nor any Subsidiary is a
party to any agreement or instrument or subject to any charter or other
corporate restriction which could reasonably be expected to have a Material
Adverse Effect. Neither the Borrower nor any Subsidiary is in default in the
performance, observance or fulfillment of any of the obligations, covenants or
conditions contained in (i) any agreement to which it is a party, which default
could reasonably be expected to have a Material Adverse Effect or (ii) any
agreement or instrument evidencing or governing Indebtedness.

         5.13. Compliance With Laws. The Borrower and its Subsidiaries have
complied with all applicable statutes, rules, regulations, orders and
restrictions of any domestic or foreign government or any instrumentality or
agency thereof having jurisdiction over the conduct of their respective
businesses or the ownership of their respective Property except for any failure
to comply with any of the foregoing which could not reasonably be expected to
have a Material Adverse Effect.

         5.14. Ownership of Properties. Except as set forth on Schedule 5.14, on
the date of this Agreement, the Borrower and its Subsidiaries will have good
title, free of all Liens other than those permitted by Section 6.16, to all of
the Property and assets reflected in the Borrower's most recent consolidated
financial statements provided to the Agent as owned by the Borrower and its
Subsidiaries.

         5.15. Plan Assets; Prohibited Transactions. The Borrower is not an
entity deemed to hold "plan assets" within the meaning of 29 C.F.R. Section
2510.3-101 of an employee benefit plan (as defined in Section 3(3) of ERISA)
which is subject to Title I of ERISA or any plan (within the meaning of Section
4975 of the Code), and neither the execution of this Agreement nor the making of
Loans hereunder gives rise to a prohibited transaction within the meaning of
Section 406 of ERISA or Section 4975 of the Code.

         5.16. Environmental Matters. In the ordinary course of its business,
the officers of the Borrower consider the effect of Environmental Laws on the
business of the Borrower and its Subsidiaries, in the course of which they
identify and evaluate potential risks and liabilities accruing to the Borrower
due to Environmental Laws. On the basis of this consideration, the Borrower has
concluded that Environmental Laws cannot reasonably be expected to have a
Material Adverse Effect. Neither the Borrower nor any Subsidiary has received
any notice to the effect that its operations are not in material compliance with
any of the requirements of applicable Environmental Laws or are the subject of
any federal or state 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 could reasonably be
expected to have a Material Adverse Effect.

         5.17. Investment Company Act. Neither the Borrower nor any Subsidiary
is an "investment company" or a company "controlled" by an "investment company",
within the meaning of the Investment Company Act of 1940, as amended.

         5.18. Public Utility Holding Company Act. Neither the Borrower nor any
Subsidiary is a "holding company" or a "subsidiary company" of a "holding
company", or an "affiliate" of a "holding company" or of a "subsidiary company"
of a "holding company", within the meaning of the Public Utility Holding Company
Act of 1935, as amended.

         5.19. Acquisition Documents. The Borrower has delivered to the Agent
true, complete and correct copies of the Acquisition Documents (including all
schedules, exhibits, annexes, amendments, supplements, modifications, and all
other material documents delivered pursuant thereto or in connection therewith).
The Acquisition Documents as originally executed and delivered by the parties
thereto have not been amended, waived, supplemented or modified in any material
respect without the consent of the Required Lenders (such consent not to be
unreasonably withheld). Each of the representations and warranties given by the
parties thereto in the Merger Agreement is true and correct in all material
respects as of the date hereof. Neither the Borrower nor any other party thereto
is in default in the performance of or compliance with any provisions thereof.
The Merger Documents are, or if not yet executed, will be when executed, in form
and substance satisfactory for effecting the Merger pursuant to such agreements
under the laws of the State of Delaware.

         5.20. Year 2000. The Borrower and its Subsidiaries have made an
assessment of the Year 2000 Issues and have developed a program (the "Year 2000
Program") for remediating the Year 2000 Issues on a timely basis. Based on such
assessment and on the Year 2000 Program neither



                                      -33-
<PAGE>   41
the Borrower nor its Subsidiaries reasonably anticipate that Year 2000 Issues
will have a Material Adverse Effect.

         5.21. Disclosure. None of the (a) information, exhibits or reports
furnished or to be furnished by the Borrower or any Subsidiary to the Agent or
to any Lender in connection with the negotiation of the Loan Documents (taken as
a whole), or (b) representations or warranties of the Borrower or any Subsidiary
contained in this Agreement, the other Loan Documents, the Transaction Documents
or any other document, certificate or written statement furnished to the Agent
or the Lenders by or on behalf of the Borrower or any Subsidiary for use in
connection with the transactions contemplated by this Agreement or the
Transaction Documents, as the case may be, contained, contains or will contain
any untrue statement of a material fact or omitted, omits or will omit to state
a material fact necessary in order to make the statements contained herein or
therein not misleading at the time such representations or warranties were made
in light of the circumstances in which the same were made. The pro forma
financial information contained in such materials is based upon good faith
estimates and assumptions believed by the Borrower to be reasonable at the time
made.


                                   ARTICLE VI

                                    COVENANTS

and (ii) any notice, complaint or citation alleging any violation of any

Borrower shall provide the Agent with written notice thereof.

                    (g) As soon as possible and in any event within ten (10)

         6.2. Use of Proceeds. The Borrower will, and will cause each Subsidiary

initial Borrowing Date, for capital expenditures, to provide funds for the
Acquisition and the payment of related fees and



                                      -35-
<PAGE>   43
expenses and to meet the general corporate needs of the Borrower and its
Subsidiaries, including the financing of Purchases permitted hereby and
commercial paper back up. The Borrower will not, nor will it permit any
Subsidiary to, use any of the proceeds of the Advances to purchase or carry any
"margin stock" (as defined in Regulation U) or to finance the Purchase of any
Person in a transaction which has not been approved and recommended by the board
of directors or functional equivalent thereof of such Person.

         6.3. Notice of Default. The Borrower will give prompt notice in writing
to the Agent upon any Authorized Officer obtaining knowledge of the occurrence

each jurisdiction in which its business is conducted.

         6.5. Taxes. The Borrower will, and will cause each Subsidiary to,
timely file complete and correct United States federal and applicable foreign,
state and local tax returns required by applicable law and pay when due all
taxes, assessments and governmental charges and levies upon it or its income,
profits or Property, except those which are being contested in good faith by
appropriate proceedings and with respect to which adequate reserves have been
set aside.

         6.6. Insurance. The Borrower will, and will cause each Subsidiary to,
maintain with financially sound and reputable insurance companies insurance on
all their Property in such amounts and covering such risks as is consistent with
sound business practice, and the Borrower will furnish to the Agent and any
Lender upon request full information as to the insurance carried; provided, that
nothing herein shall prohibit the Borrower and its Subsidiaries from maintaining
self-insurance in lieu of third party insurance consistent with past practices.

         6.7. Compliance with Laws. The Borrower will, and will cause each
Subsidiary to, comply with all laws, rules, regulations, orders, writs,
judgments, injunctions, decrees or awards to which it may be subject, the

Subsidiary to, do all things necessary to maintain, preserve, protect and keep
its Property in good repair, working order and condition, and make all necessary

accounts and other financial records of the Borrower and each Subsidiary, and to
discuss the affairs, finances and accounts of the Borrower and each Subsidiary
with, and to be advised as to the same by, their respective officers, directors
and independent public accountants at such reasonable times and intervals as the
Lenders may designate. The Borrower will keep or cause to be kept, and cause

Substantial Portion of the Property of the Borrower and its Subsidiaries.

         6.14. Investments and Purchases. The Borrower will not, nor will it
permit any Subsidiary to, make or suffer to exist any Investments (including,

Subsidiaries), or commitments therefor, or to create any Subsidiary or to become

seek a waiver of the minimum funding standards under ERISA, (ii) terminate or

                                  ARTICLE VIII

                 ACCELERATION, WAIVERS, AMENDMENTS AND REMEDIES

         8.1. Acceleration. If any Default described in Section 7.6 or 7.7
occurs with respect to the Borrower, the obligations of the Lenders to make
Loans hereunder shall automatically terminate and the Obligations shall
immediately become due and payable without any election or action on the part of
the Agent or any Lender. If any other Default occurs, the Required Lenders (or
the Agent with the consent of the Required Lenders) may terminate or suspend the
obligations of the Lenders to make Loans hereunder, or declare the Obligations
to be due and payable, or both, whereupon the



                                      -45-
<PAGE>   53
Obligations shall become immediately due and payable, without presentment,
demand, protest or notice of any kind, all of which the Borrower hereby
expressly waives.

         If, within thirty (30) days after acceleration of the maturity of the
Obligations or termination of the obligations of the Lenders to make Loans
hereunder as a result of any Default (other than any Default as described in
Section 7.6 or 7.7 with respect to the Borrower) and before any judgment or
decree for the payment of the Obligations due shall have been obtained or
entered, the Required Lenders (in their sole discretion) shall so direct, the
Agent shall, by notice to the Borrower, rescind and annul such acceleration
and/or termination.

         8.2. Amendments. Subject to the provisions of this Article VIII, the
Required Lenders (or the Agent with the consent in writing of the Required
Lenders) and the Borrower may enter into agreements supplemental hereto for the
purpose of adding or modifying any provisions to the Loan Documents or changing
in any manner the rights of the Lenders or the Borrower hereunder or waiving any
Default hereunder; provided, however, that no such supplemental agreement shall,
without the consent of each Lender:

                  (a) Extend the final maturity of any Loan or forgive all or
any portion of the principal amount thereof, or reduce the rate or extend the
time of payment of interest or fees hereunder;

                  (b) Reduce the percentage specified in the definition of
Required Lenders;

                  (c) Reduce the amount of or extend the date for the mandatory
payments required under Section 2.1(b);

                  (d) Extend the Facility Termination Date, or increase the
amount of the Commitment of any Lender hereunder;

                  (e) Amend this Section 8.2;

                  (f) Release any Guarantor from the Subsidiary Guaranty; or

                  (g) Permit any assignment by the Borrower of its Obligations
or its rights hereunder.

No amendment of any provision of this Agreement relating to the Agent shall be
effective without the written consent of the Agent. The Agent may waive payment
of the fee required under Section 12.3.2 without obtaining the consent of any
other party to this Agreement.

         8.3. Preservation of Rights. No delay or omission of the Lenders or the
Agent to exercise any right under the Loan Documents shall impair such right or
be construed to be a waiver of any Default or an acquiescence therein, and the
making of a Loan notwithstanding the existence of a Default or the inability of
the Borrower to satisfy the conditions precedent to such Loan shall not
constitute any waiver or acquiescence. Any single or partial exercise of any
such right shall not



                                      -46-
<PAGE>   54
preclude other or further exercise thereof or the exercise of any other right,
and no waiver, amendment or other variation of the terms, conditions or
provisions of the Loan Documents whatsoever shall be valid unless in writing
signed by the Lenders required pursuant to Section 8.2, and then only to the
extent in such writing specifically set forth. All remedies contained in the
Loan Documents or by law afforded shall be cumulative and all shall be available
to the Agent and the Lenders until the Obligations have been paid in full.


                                   ARTICLE IX

                               GENERAL PROVISIONS

         9.1. Survival of Representations. All representations and warranties of
the Borrower contained in this Agreement or of the Borrower or any Subsidiary
contained in any Loan Document shall survive delivery of the Notes (if any) and
the making of the Loans herein contemplated.

         9.2. Governmental Regulation. Anything contained in this Agreement to
the contrary notwithstanding, no Lender shall be obligated to extend credit to
the Borrower in violation of any limitation or prohibition provided by any
applicable statute or regulation.

         9.3. Headings. Section headings in the Loan Documents are for
convenience of reference only, and shall not govern the interpretation of any of
the provisions of the Loan Documents.

         9.4. Entire Agreement. The Loan Documents embody the entire agreement
and understanding among the Borrower, the Agent and the Lenders and supersede
all prior agreements and understandings among the Borrower, the Agent and the
Lenders relating to the subject matter thereof other than the fee letter dated
July 6, 1998 in favor of First Chicago and the Arranger.

         9.5. Numbers of Documents. All statements, notices, closing documents,
and requests hereunder shall be furnished to the Agent with sufficient
counterparts so that the Agent may furnish one to each of the Lenders.

         9.6. Several Obligations; Benefits of this Agreement. The respective
obligations of the Lenders hereunder are several and not joint and no Lender
shall be the partner or agent of any other (except to the extent to which the
Agent is authorized to act as such). The failure of any Lender to perform any of
its obligations hereunder shall not relieve any other Lender from any of its
obligations hereunder. This Agreement shall not be construed so as to confer any
right or benefit upon any Person other than the parties to this Agreement and
their respective successors and assigns, provided, however, that the parties
hereto expressly agree that the Arranger shall enjoy the benefits of the
provisions of Sections 9.6, 9.10 and 10.11 to the extent specifically set forth
therein and shall have the right to enforce such provisions on its own behalf
and in its own name to the same extent as if it were a party to this Agreement.

         9.7. Expenses; Indemnification. (a) The Borrower shall reimburse the
Agent and the Arranger for any reasonable costs, internal charges and
out-of-pocket expenses (including



                                      -47-
<PAGE>   55
reasonable attorneys' fees and time charges of attorneys for the Agent, which
attorneys may be employees of the Agent) paid or incurred by the Agent or the
Arranger in connection with the preparation, negotiation, execution, delivery,
syndication, review, amendment, modification, and administration of the Loan
Documents. The Borrower also agrees to reimburse the Agent, the Arranger and the
Lenders for any reasonable costs, internal charges and out-of-pocket expenses
(including reasonable attorneys' fees and time charges of attorneys for the
Agent, the Arranger and the Lenders, which attorneys may be employees of the
Agent, the Arranger or the respective Lenders) paid or incurred by the Agent,
the Arranger or any Lender in connection with the collection and enforcement of
the Loan Documents.

         (b) The Borrower hereby further agrees to indemnify the Agent, the
Arranger and each Lender, its directors, officers and employees against all
losses, claims, damages, penalties, judgments, liabilities and expenses
(including, without limitation, all expenses of litigation or preparation
therefor whether or not the Agent, the Arranger or any Lender is a party
thereto) which any of them may pay or incur arising out of or relating to this
Agreement, the other Loan Documents, the transactions contemplated hereby or the
direct or indirect application or proposed application of the proceeds of any
Loan hereunder except to the extent that they resulted from the gross negligence
or willful misconduct of the party seeking indemnification. The obligations of
the Borrower under this Section 9.7 shall survive the termination of this
Agreement.

         9.8. Accounting. Except as provided to the contrary herein, all
accounting terms used herein shall be interpreted and all accounting
determinations hereunder shall be made in accordance with Agreement Accounting
Principles.

         9.9. Severability of Provisions. Any provision in any Loan Document
that is held to be inoperative, unenforceable, or invalid in any jurisdiction
shall, as to that jurisdiction, be inoperative, unenforceable, or invalid
without affecting the remaining provisions in that jurisdiction or the
operation, enforceability, or validity of that provision in any other
jurisdiction, and to this end the provisions of all Loan Documents are declared
to be severable.

         9.10. Nonliability of Lenders. The relationship between the Borrower on
the one hand and the Lenders and the Agent on the other hand shall be solely
that of borrower and lender. Neither the Agent, the Arranger nor any Lender
shall have any fiduciary responsibilities to the Borrower. Neither the Agent,
the Arranger nor any Lender undertakes any responsibility to the Borrower to
review or inform the Borrower of any matter in connection with any phase of the
Borrower's business or operations. The Borrower agrees that neither the Agent,
the Arranger nor any Lender shall have liability to the Borrower (whether
sounding in tort, contract or otherwise) for losses suffered by the Borrower in
connection with, arising out of, or in any way related to, the transactions
contemplated and the relationship established by the Loan Documents, or any act,
omission or event occurring in connection therewith, unless such losses resulted
from the gross negligence or willful misconduct of the party from which recovery
is sought. Neither the Agent, the Arranger nor any Lender shall have any
liability with respect to, and the Borrower hereby waives, releases and agrees
not to sue for, any special, indirect or consequential damages suffered by the
Borrower in connection with, arising out of, or in any way related to the Loan
Documents or the transactions contemplated thereby.

         9.11. Confidentiality. Each Lender agrees to hold any confidential
information which it may receive from the Borrower pursuant to this Agreement in
confidence, except for disclosure (i) to its Affiliates and to other Lenders and
their respective Affiliates, (ii) to legal counsel, accountants, and other
professional advisors to that Lender or to a Transferee, (iii) to regulatory
officials, (iv) to any Person as requested pursuant to or as required by law,
regulation, or legal process, (v) to any Person in connection with any legal
proceeding to which that Lender is a party (in which case prior notice of such
disclosure shall be given to the Borrower to the extent practicable and not
otherwise prohibited under such proceeding), and (vi) permitted by Section 12.4.

         9.12. Nonreliance. Each Lender hereby represents that it is not relying
on or looking to any margin stock (as defined in Regulation U of the Board of
Governors of the Federal Reserve System) for the repayment of the Loans provided
for herein.

         9.13. Disclosure. The Borrower and each Lender hereby (a) acknowledge
and agree that First Chicago and/or its Affiliates from time to time may hold
other investments in, make other loans to or have other relationships with the
Borrower and its Affiliates, and (b) waive any liability of First Chicago or
such Affiliate to the Borrower or any Lender, respectively, arising out of or
resulting from such investments, loans or relationships other than liabilities
arising out of the gross negligence or willful misconduct of First Chicago or
its Affiliates.


                                    ARTICLE X

                                    THE AGENT

         10.1. Appointment; Nature of Relationship. The First National Bank of
Chicago is hereby appointed by each of the Lenders as its contractual
representative (herein referred to as the "Agent") hereunder and under each
other Loan Document, and each of the Lenders irrevocably authorizes the Agent to
act as the contractual representative of such Lender with the rights and duties
expressly set forth herein and in the other Loan Documents. The Agent agrees to
act as such contractual representative upon the express conditions contained in
this Article X. Notwithstanding the use of the defined term "Agent," it is
expressly understood and agreed that the Agent shall not have any fiduciary
responsibilities to any Lender by reason of this Agreement or any other Loan
Document and that the Agent is merely acting as the contractual representative
of the Lenders with only those duties as are expressly set forth in this
Agreement and the other Loan Documents. In its capacity as the Lenders'
contractual representative, the Agent (i) does not hereby assume any fiduciary
duties to any of the Lenders, (ii) is a "representative" of the Lenders within
the meaning of Section 9-105 of the Uniform Commercial Code and (iii) is acting
as an independent contractor, the rights and duties of which are limited to
those expressly set forth in this Agreement and the other Loan Documents. Each
of the Lenders hereby agrees to assert no claim against the Agent on any agency
theory or any other theory of liability for breach of fiduciary duty, all of
which claims each Lender hereby waives.

         10.2. Powers. The Agent shall have and may exercise such powers under
the Loan Documents as are specifically delegated to the Agent by the terms of
each thereof, together with



                                      -49-
<PAGE>   57
such powers as are reasonably incidental thereto. The Agent shall have no
implied duties to the Lenders, or any obligation to the Lenders to take any
action thereunder except any action specifically provided by the Loan Documents
to be taken by the Agent.

         10.3. General Immunity. Neither the Agent nor any of its directors,
officers, agents or employees shall be liable to the Borrower, the Lenders or
any Lender for any action taken or omitted to be taken by it or them hereunder
or under any other Loan Document or in connection herewith or therewith except
to the extent such action or inaction is determined in a final non-appealable
judgment by a court of competent jurisdiction to have arisen from the gross
negligence or willful misconduct of such Person.

         10.4. No Responsibility for Loans, Recitals, etc. Neither the Agent nor
any of its directors, officers, agents or employees shall be responsible for or
have any duty to ascertain, inquire into, or verify (a) any statement, warranty
or representation made in connection with any Loan Document or any borrowing
hereunder; (b) the performance or observance of any of the covenants or
agreements of any obligor under any Loan Document, including, without
limitation, any agreement by an obligor to furnish information directly to each
Lender; (c) the satisfaction of any condition specified in Article IV, except
receipt of items required to be delivered solely to the Agent; (d) the existence
or possible existence of any Default or Unmatured Default; (e) the validity,
enforceability, effectiveness, sufficiency or genuineness of any Loan Document
or any other instrument or writing furnished in connection therewith; (f) the
value, sufficiency, creation, perfection or priority of any Lien in any
collateral security; or (g) the financial condition of the Borrower or any
guarantor of any of the Obligations or of any of the Borrower's or any such
guarantor's respective Subsidiaries. The Agent shall have no duty to disclose to
the Lenders information that is not required to be furnished by the Borrower to
the Agent at such time, but is voluntarily furnished by the Borrower to the
Agent (either in its capacity as Agent or in its individual capacity).

         10.5. Action on Instructions of Lenders. The Agent shall in all cases
be fully protected in acting, or in refraining from acting, hereunder and under
any other Loan Document in accordance with written instructions signed by the
Required Lenders, and such instructions and any action taken or failure to act
pursuant thereto shall be binding on all of the Lenders. The Lenders hereby
acknowledge that the Agent shall be under no duty to take any discretionary
action permitted to be taken by it pursuant to the provisions of this Agreement
or any other Loan Document unless it shall be requested in writing to do so by
the Required Lenders. The Agent shall be fully justified in failing or refusing
to take any action hereunder and under any other Loan Document unless it shall
first be indemnified to its satisfaction by the Lenders pro rata against any and
all liability, cost and expense that it may incur by reason of taking or
continuing to take any such action.

         10.6. Employment of Agents and Counsel. The Agent may execute any of
its duties as Agent hereunder and under any other Loan Document by or through
employees, agents, and attorneys-in-fact and shall not be answerable to the
Lenders, except as to money or securities received by it or its authorized
agents, for the default or misconduct of any such agents or attorneys-in-fact
selected by it with reasonable care. The Agent shall be entitled to advice of
counsel concerning the contractual arrangement between the Agent and the Lenders
and all matters pertaining to the Agent's duties hereunder and under any other
Loan Document.



                                      -50-
<PAGE>   58
         10.7. Reliance on Documents; Counsel. The Agent shall be entitled to
rely upon any Note, notice, consent, certificate, affidavit, letter, telegram,
statement, paper or document believed by it to be genuine and correct and to
have been signed or sent by the proper person or persons, and, in respect to
legal matters, upon the opinion of counsel selected by the Agent, which counsel
may be employees of the Agent.

         10.8. Agent's Reimbursement and Indemnification. The Lenders agree to
reimburse and indemnify the Agent ratably in proportion to their respective
Commitments (or, if the Commitments have been terminated, in proportion to their
Commitments immediately prior to such termination) (i) for any amounts not
reimbursed by the Borrower for which the Agent is entitled to reimbursement by
the Borrower under the Loan Documents, (ii) for any other expenses incurred by
the Agent on behalf of the Lenders, in connection with the preparation,
execution, delivery, administration and enforcement of the Loan Documents
(including, without limitation, for any expenses incurred by the Agent in
connection with any dispute between the Agent and any Lender or between two or
more of the Lenders) and (iii) for any liabilities, obligations, losses,
damages, penalties, actions, judgments, suits, costs, expenses or disbursements
of any kind and nature whatsoever which may be imposed on, incurred by or
asserted against the Agent in any way relating to or arising out of the Loan
Documents or any other document delivered in connection therewith or the
transactions contemplated thereby (including, without limitation, for any such
amounts incurred by or asserted against the Agent in connection with any dispute
between the Agent and any Lender or between two or more of the Lenders), or the
enforcement of any of the terms of the Loan Documents or of any such other
documents, provided that no Lender shall be liable for any of the foregoing to
the extent any of the foregoing is found in a final non-appealable judgment by a
court of competent jurisdiction to have resulted from the gross negligence or
willful misconduct of the Agent. The obligations of the Lenders under this
Section 10.8 shall survive payment of the Obligations and termination of this
Agreement.

         10.9. Notice of Default. The Agent shall not be deemed to have
knowledge or notice of the occurrence of any Default or Unmatured Default
hereunder unless the Agent has received written notice from a Lender or the
Borrower referring to this Agreement describing such Default or Unmatured
Default and stating that such notice is a "notice of default". In the event that
the Agent receives such a notice, the Agent shall give prompt notice thereof to
the Lenders.

         10.10. Rights as a Lender. In the event the Agent is a Lender, the
Agent shall have the same rights and powers hereunder and under any other Loan
Document with respect to its Commitment and its Loans as any Lender and may
exercise the same as though it were not the Agent, and the term "Lender" or
"Lenders" shall, at any time when the Agent is a Lender, unless the context
otherwise indicates, include the Agent in its individual capacity. The Agent and
its Affiliates may accept deposits from, lend money to, and generally engage in
any kind of trust, debt, equity or other transaction, in addition to those
contemplated by this Agreement or any other Loan Document, with the Borrower or
any of its Subsidiaries in which the Borrower or such Subsidiary is not
restricted hereby from engaging with any other Person.

         10.11. Lender Credit Decision. Each Lender acknowledges that it has,
independently and without reliance upon the Agent, the Arranger or any other
Lender and based on the financial



                                      -51-
<PAGE>   59
statements prepared by the Borrower and such other documents and information as
it has deemed appropriate, made its own credit analysis and decision to enter
into this Agreement and the other Loan Documents. Each Lender also acknowledges
that it will, independently and without reliance upon the Agent, the Arranger or
any other Lender and based on such documents and information as it shall deem
appropriate at the time, continue to make its own credit decisions in taking or
not taking action under this Agreement and the other Loan Documents.

         10.12. Successor Agent. The Agent may resign at any time by giving
written notice thereof to the Lenders and the Borrower, such resignation to be
effective upon the appointment of a successor Agent or, if no successor Agent
has been appointed, forty-five (45) days after the retiring Agent gives notice
of its intention to resign. The Agent may be removed at any time with or without
cause by written notice received by the Agent from the Required Lenders, such
removal to be effective on the date specified by the Required Lenders. Upon any
such resignation or removal, the Required Lenders shall have the right to
appoint, on behalf of the Borrower and the Lenders, a successor Agent. If no
successor Agent shall have been so appointed by the Required Lenders within
thirty (30) days after the resigning Agent's giving notice of its intention to
resign, then the resigning Agent may appoint, on behalf of the Borrower and the
Lenders, a successor Agent. Notwithstanding the previous sentence, the Agent may
at any time without the consent of the Borrower or any Lender, appoint any of
its Affiliates which is a commercial bank as a successor Agent hereunder. If the
Agent has resigned or been removed and no successor Agent has been appointed,
the Lenders may perform all the duties of the Agent hereunder and the Borrower
shall make all payments in respect of the Obligations to the applicable Lender
and for all other purposes shall deal directly with the Lenders. No successor
Agent shall be deemed to be appointed hereunder until such successor Agent has
accepted the appointment. Any such successor Agent shall be a commercial bank
having capital and retained earnings of at least $100,000,000. Upon the
acceptance of any appointment as Agent hereunder by a successor Agent, such
successor Agent shall thereupon succeed to and become vested with all the
rights, powers, privileges and duties of the resigning or removed Agent. Upon
the effectiveness of the resignation or removal of the Agent, the resigning or
removed Agent shall be discharged from its duties and obligations hereunder and
under the Loan Documents. After the effectiveness of the resignation or removal
of an Agent, the provisions of this Article X shall continue in effect for the
benefit of such Agent in respect of any actions taken or omitted to be taken by
it while it was acting as the Agent hereunder and under the other Loan
Documents. In the event that there is a successor to the Agent by merger, or the
Agent assigns its duties and obligations to an Affiliate pursuant to this
Section 10.12, then the term "Corporate Base Rate" as used in this Agreement
shall mean the prime rate, base rate or other analogous rate of the new Agent.

         10.13. Agent's Fee. The Borrower agrees to pay to the Agent, for its
own account, the fees agreed to by the Borrower and the Agent pursuant to that
certain fee letter dated July 6, 1998, or as otherwise agreed from time to time.

         10.14. Delegation to Affiliates. The Borrower and the Lenders agree
that the Agent may delegate any of its duties under this Agreement to any of its
Affiliates. Any such Affiliate (and such Affiliate's directors, officers, agents
and employees) which performs duties in connection with this



                                      -52-
<PAGE>   60
Agreement shall be entitled to the same benefits of the indemnification, waiver
and other protective provisions to which the Agent is entitled under Articles IX
and X.

         10.15. Documentation Agent; Syndication Agent. None of the Lenders
identified on the facing page or signature pages of this Agreement as the
"documentation agent" or the "syndication agent" shall have any right, power,
obligation, liability, responsibility or duty under this Agreement other than
those applicable to all Lenders as such. Without limiting the foregoing, none of
the Lenders so identified as the "documentation agent" or "syndication agent"
shall have or be deemed to have any fiduciary relationship with any Lender. Each
Lender acknowledges that it has not relied, and will not rely, on any of the
Lenders so identified in deciding to enter into this Agreement or in taking or
not taking action hereunder.


                                   ARTICLE XI

                            SETOFF; RATABLE PAYMENTS

         11.1. Setoff. In addition to, and without limitation of, any rights of
the Lenders under applicable law, if the Borrower becomes insolvent, however
evidenced, or any Default occurs and for so long as such Default is continuing,
any and all deposits (including all account balances, whether provisional or
final and whether or not collected or available) and any other Indebtedness at
any time held or owing by any Lender to or for the credit or account of the
Borrower may be offset and applied toward the payment of the Obligations owing
to such Lender, whether or not the Obligations, or any part hereof, shall then
be due.

         11.2. Ratable Payments. If any Lender, whether by setoff or otherwise,
has payment made to it upon its Loans (other than payments received pursuant to
Section 3.1, 3.2, 3.4 or 3.5) in a greater proportion than that received by any
other Lender, such Lender agrees, promptly upon demand, to purchase a portion of
the Loans held by the other Lenders so that after such purchase each Lender will
hold its ratable proportion of Loans. If any Lender, whether in connection with
setoff or amounts which might be subject to setoff or otherwise, receives
collateral or other protection for its Obligations or such amounts which may be
subject to setoff, such Lender agrees, promptly upon demand, to take such action
necessary such that all Lenders share in the benefits of such collateral ratably
in proportion to their Loans. In case any such payment is disturbed by legal
process, or otherwise, appropriate further adjustments shall be made.



                                   ARTICLE XII

                BENEFIT OF AGREEMENT; ASSIGNMENTS; PARTICIPATIONS

         12.1. Successors and Assigns. The terms and provisions of the Loan
Documents shall be binding upon and inure to the benefit of the Borrower and the
Lenders and their respective successors and assigns, except that (a) the
Borrower shall not have the right to assign its rights or



                                      -53-
<PAGE>   61
obligations under the Loan Documents and (b) any assignment by any Lender must
be made in compliance with Section 12.3. Notwithstanding clause (b) of this
Section, any Lender may at any time, without the consent of the Borrower or the
Agent, assign all or any portion of its rights under this Agreement and any Note
to a Federal Reserve Bank; provided, however, that no such assignment to a
Federal Reserve Bank shall release the transferor Lender from its obligations
hereunder. The Agent may treat the Person which made any Loan or which holds any
Note as the owner thereof for all purposes hereof unless and until such Person
complies with Section 12.3 in the case of an assignment thereof or, in the case
of any other transfer, a written notice of the transfer is filed with the Agent.
Any assignee or transferee of the rights to any Loan or any Note agrees by
acceptance of such transfer or assignment to be bound by all the terms and
provisions of the Loan Documents. Any request, authority or consent of any
Person, who at the time of making such request or giving such authority or
consent is the owner of the rights to any Loan (whether or not a Note has been
issued in evidence thereof), shall be conclusive and binding on any subsequent
holder, transferee or assignee of the rights to such Loan.

         12.2. Participations.

                  12.2.1 Permitted Participants; Effect. Any Lender may, in the
         ordinary course of its business and in accordance with applicable law,
         at any time sell to one or more banks or other entities
         ("Participants") participating interests in any Loan owing to such
         Lender, any Note held by such Lender, any Commitment of such Lender or
         any other interest of such Lender under the Loan Documents. In the
         event of any such sale by a Lender of participating interests to a
         Participant, such Lender's obligations under the Loan Documents shall
         remain unchanged, such Lender shall remain solely responsible to the
         other parties hereto for the performance of such obligations, such
         Lender shall remain the owner of its Loans and the holder of any Note
         issued to it in evidence thereof for all purposes under the Loan
         Documents, all amounts payable by the Borrower under this Agreement
         shall be determined as if such Lender had not sold such participating
         interests, and the Borrower and the Agent shall continue to deal solely
         and directly with such Lender in connection with such Lender's rights
         and obligations under the Loan Documents.

                  12.2.2. Voting Rights. Each Lender shall retain the sole right
         to approve, without the consent of any Participant, any amendment,
         modification or waiver of any provision of the Loan Documents other
         than any amendment, modification or waiver with respect to any Loan or
         Commitment in which such Participant has an interest which forgives
         principal, interest or fees or reduces the interest rate or fees
         payable with respect to any such Loan or Commitment, extends the
         Facility Termination Date, postpones any date fixed for any
         regularly-scheduled payment of principal of, or interest or fees on,
         any such Loan or Commitment, releases any guarantor of any such Loan or
         releases all or substantially all of the collateral, if any, securing
         any such Loan.

                  12.2.3. Benefit of Setoff. The Borrower agrees that each
         Participant shall be deemed to have the right of setoff provided in
         Section 11.1 in respect of its participating interest in amounts owing
         under the Loan Documents to the same extent as if the amount of its
         participating interest were owing directly to it as a Lender under the
         Loan Documents,



                                      -54-
<PAGE>   62
         provided that each Lender shall retain the right of setoff provided in
         Section 11.1 with respect to the amount of participating interests sold
         to each Participant. The Lenders agree to share with each Participant,
         and each Participant, by exercising the right of setoff provided in
         Section 11.1, agrees to share with each Lender, any amount received
         pursuant to the exercise of its right of setoff, such amounts to be
         shared in accordance with Section 11.2 as if each Participant were a
         Lender.

         12.3. Assignments.

                  12.3.1. Permitted Assignments. Any Lender may, in the ordinary
         course of its business and in accordance with applicable law, at any
         time assign to one or more banks or other entities ("Purchasers") all
         or any part of its rights and obligations under the Loan Documents.
         Such assignment shall be substantially in the form of Exhibit C or in
         such other form as may be agreed to by the parties thereto. The consent
         of the Borrower and the Agent shall be required prior to an assignment
         becoming effective with respect to a Purchaser which is not a Lender or
         an Affiliate thereof; provided, however, that if a Default has occurred
         and is continuing, the consent of the Borrower shall not be required.
         Such consent shall not be unreasonably withheld or delayed. Each such
         assignment shall (unless each of the Borrower and the Agent otherwise
         consents) (a) be in an amount not less than the lesser of (i)
         $10,000,000 (provided, however, that such amount shall be reduced
         dollar for dollar by the amount being simultaneously assigned under the
         Other Credit Agreement pursuant to subsection (b) of this sentence) or
         (ii) the remaining amount of the assigning Lender's Commitment
         (calculated as at the date of such assignment) and (b) assign a like
         percentage of such Lender's Other Loans and Commitment (as defined in
         the Other Credit Agreement) under the Other Credit Agreement.

                  12.3.2. Effect; Effective Date. Upon (a) delivery to the Agent
         of a notice of assignment, substantially in the form attached as
         Exhibit I to Exhibit C (a "Notice of Assignment"), together with any
         consents required by Section 12.3.1, and (b) payment of a $3,500 fee to
         the Agent for processing such assignment, such assignment shall become
         effective on the effective date specified in such Notice of Assignment.
         The Notice of Assignment shall contain a representation by the
         Purchaser to the effect that none of the consideration used to make the
         purchase of the Commitment and Loans under the applicable assignment
         agreement are "plan assets" as defined under ERISA and that the rights
         and interests of the Purchaser in and under the Loan Documents will not
         be "plan assets" under ERISA. On and after the effective date of such
         assignment, such Purchaser shall for all purposes be a Lender party to
         this Agreement and any other Loan Document executed by or on behalf of
         the Lenders and shall have all the rights and obligations of a Lender
         under the Loan Documents, to the same extent as if it were an original
         party hereto, and no further consent or action by the Borrower, the
         Lenders or the Agent shall be required to release the transferor Lender
         with respect to the percentage of the Aggregate Commitment and Loans
         assigned to such Purchaser. Upon the consummation of any assignment to
         a Purchaser pursuant to this Section 12.3.2, the transferor Lender, the
         Agent and the Borrower shall, if the transferor Lender or the Purchaser
         desires that its Loans be evidenced by Notes, make appropriate
         arrangements so that new Notes or, as appropriate, replacement Notes
         are issued



                                      -55-
<PAGE>   63
         to such transferor Lender and new Notes or, as appropriate, replacement
         Notes, are issued to such Purchaser, in each case in principal amounts
         reflecting their respective Commitments, as adjusted pursuant to such
         assignment.

         12.4. Dissemination of Information. The Borrower authorizes each Lender
to disclose to any Participant or Purchaser or any other Person acquiring an
interest in the Loan Documents by operation of law (each a "Transferee") and any
prospective Transferee any and all information in such Lender's possession
concerning the creditworthiness of the Borrower and its Subsidiaries; provided
that each Transferee and prospective Transferee agrees to be bound by Section
9.11 of this Agreement.

         12.5. Tax Treatment. If any interest in any Loan Document is
transferred to any Transferee which is organized under the laws of any
jurisdiction other than the United States or any State thereof, the transferor
Lender shall cause such Transferee, concurrently with the effectiveness of such
transfer, to comply with the provisions of Section 3.5(d).


                                  ARTICLE XIII

                                     NOTICES

         13.1. Notices. Except as otherwise permitted by Section 2.14 with
respect to Borrowing Notices, all notices, requests and other communications to
any party hereunder shall be in writing (including electronic transmission,
facsimile transmission or similar writing) and shall be given to such party: (a)
in the case of the Borrower or the Agent, at its address or facsimile number set
forth on the signature pages hereof, (b) in the case of any Lender, at its
address or facsimile number set forth below its signature hereto or (c) in the
case of any party, at such other address or facsimile number as such party may
hereafter specify for the purpose by notice to the Agent and the Borrower in
accordance with the provisions of this Section 13.1. Each such notice, request
or other communication shall be effective (i) if given by facsimile
transmission, when transmitted to the facsimile number specified in this Section
and confirmation of receipt is received, (ii) if given by mail, 72 hours after
such communication is deposited in the mails with first class postage prepaid,

         For the purposes of this Schedule, the following terms have the
following meanings, subject to the final paragraph of this Schedule:

         "Level I Status" exists at any date if, on such date, the Borrower's
Moody's Rating is A3 or better or the Borrower's S&P Rating is A- or better.**

         "Level II Status" exists at any date if, on such date, (i) the Borrower
has not qualified for Level I Status and (ii) the Borrower's Moody's Rating is
Baa1 or better or the Borrower's S&P Rating is BBB+ or better.**

         "Level III Status" exists at any date if, on such date, (i) the
Borrower has not qualified for Level I Status or Level II Status and (ii) the
Borrower's Moody's Rating is Baa2 or better or the Borrower's S&P Rating is BBB
or better.**

- ----------------

* "Utilization" means, for any day, a percentage equal to the aggregate
principal amount of Loans, Other Loans and "Facility Letters of Credit" (as
defined in the Other Credit Agreement) outstanding on the close of business (if
a Business Day) on such day divided by the sum on such day of the Aggregate
Commitment and the "Aggregate Commitment" under the Other Agreement.

** In the event that a split occurs between the two ratings, then the rating
corresponding to the higher of the two ratings shall apply. However, if the
split is greater than one level, then the pricing shall be based upon the
average of the two ratings; if the split is greater than two levels, then the
pricing shall be based upon the rating one level above the lowest of the two
ratings. In the event that one of the ratings is BB+ or Ba1 or lower, then the
pricing shall be based upon the lowest of the two ratings.
<PAGE>   67
         "Level IV Status" exists at any date if, on such date, (i) the Borrower
has not qualified for Level I Status, Level II Status or Level III Status and
(ii) the Borrower's Moody's Rating is Baa3 or better or the Borrower's S&P
Rating is BBB- or better.***

         "Level V Status" exists at any date if, on such date, the Borrower has
not qualified for Level I Status, Level II Status, Level III Status or Level IV
Status.***

         "Moody's Rating" means, at any time, the rating issued by Moody's and
then in effect with respect to the Borrower's senior unsecured long-term debt
securities without third-party credit enhancement.

         "S&P Rating" means, at any time, the rating issued by S&P and then in
effect with respect to the Borrower's senior unsecured long-term debt securities
without third-party credit enhancement.

         "Status" means either Level I Status, Level II Status, Level III
Status, Level IV Status or Level V Status.

         The Applicable Margin and Applicable Fee Rate shall be determined in
accordance with the foregoing table based on the Borrower's Status as determined
from its then-current Moody's and S&P Ratings. The credit rating in effect on
any date for the purposes of this Schedule is that in effect at the close of
business on such date. If at any time the Borrower has no Moody's Rating or no
S&P Rating, Level V Status shall exist.

         Notwithstanding the foregoing, the Borrower's Status shall be fixed at
Level III from the initial Borrowing Date until and including June 30, 1999.




- ----------------

*** In the event that a split occurs between the two ratings, then the rating
corresponding to the higher of the two ratings shall apply. However, if the
split is greater than one level, then the pricing shall be based upon the
average of the two ratings; if the split is greater than two levels, then the
pricing shall be based upon the rating one level above the lowest of the two
ratings. In the event that one of the ratings is BB+ or Ba1 or lower, then the
pricing shall be based upon the lowest of the two ratings.
