CREDIT AGREEMENTS AND SHORT-TERM BORROWINGS

At March 31, 1996, the Company had a domestic credit facility with two banks
providing for borrowings up to $50.0 million, reduced by the value of
outstanding letters of credit issued by the banks on behalf of the Company
which totaled $30.2 million at March 31, 1996. These outstanding letters of
credit included $27.2 million issued in support of foreign subsidiary credit
arrangements. There were no borrowings under the domestic credit facility
during the first quarter.

In early May 1996, the Company entered into a new, five-year, unsecured $160.0
million revolving credit facility with several banks. This new facility, which
replaced the existing domestic credit facility, provides for borrowings and
issuances of letters of credit in multiple currencies. The new facility
provides for various borrowing rates, including borrowing rates based on the
prime rate or 0.25% to 0.70% above the LIBOR rate. A commitment fee of 0.10% to
0.225% on the daily average unused portion of the facility is also assessed.
The maximum borrowings available under the facility are reduced by the value of
outstanding letters of credit issued by the banks on behalf of the Company.
This new facility contains various financial covenants.

Two of the Company's foreign subsidiaries also have several short-term credit
agreements providing for borrowings denominated in various foreign currencies
of up to $106.0 million, of which $92.2 million was outstanding at March 31,
1996. The interest rates on these agreements are market rates which ranged from
4% to 6% at March 31, 1996.

INCOME TAX EXPENSE

The Company's income tax expense includes federal, foreign, and state
(including Puerto Rico) income taxes. The estimated effective income tax rate
is based upon estimates for the full year for a number of variables including,
among other things, forecasted income in the United States and foreign
jurisdictions. The effective tax rate could change as estimates of these and
other variables change throughout the year.

COMMITMENTS AND CONTINGENCIES

Contingent Liabilities

The Company periodically sells customer receivables and operating leases under
agreements which contain recourse provisions. At March 31, 1996, $3.5 million
of certain receivables sold during 1995 were outstanding and subject to
recourse provisions which would require the Company to repurchase up to 100% of
the receivable balance upon customer default. Additionally, the Company could
be obligated to





                                Page 7 0f 20
<PAGE>   8
repurchase a portion of certain receivables and operating leases which were
sold in 1995 on a partial recourse basis, the terms of which allow the Company
to limit its risk of loss to approximately $7.8 million at March 31, 1996. The
Company also has guarantees of $28.8 million outstanding at March 31, 1996
supporting bid and performance bonds to customers and others, of which $3.0
million were collateralized by letters of credit issued under the Company's
credit facility. The Company believes it has adequate reserves for any ultimate
losses associated with these contingencies.

The Company, in management of its exposure to fluctuations in foreign currency
exchange rates, enters into forward foreign exchange contracts for both firm
commitments and anticipated transactions of sales and purchases which are
denominated in foreign currencies. At March 31, 1996, the Company had forward
foreign exchange contracts of $20.2 million outstanding.

Litigation

On July 20, 1993, the Company filed suit against Advanced Fibre Communications
("AFC"), a California corporation; Quadrium Corporation ("Quadrium"), a
California corporation; and two individuals. The Company seeks a declaratory
judgment that the two individuals are not entitled to any stock options or cash
payments under the Company's 1990 Stock Option and Cash Payment Plan because of
these defendants' alleged breaches of certain employment-related agreements
with the Company. The Company further seeks a declaration that AFC's products
are the proprietary property of the Company under the terms of certain
Proprietary Information Agreements or certain Consulting Agreements with
Quadrium. The Company also seeks unspecified damages for breaches of contract,
civil conspiracy, and tortious interference. The individual defendants have
both filed counterclaims whereby they claim entitlement to certain stock
options and cash payments under several of the Company's stock option plans.
AFC has also filed a counterclaim alleging that the Company has violated the
Sherman Antitrust Act and certain state antitrust statutes, and further claims
that the Company has (1) tortiously interfered with existing and prospective
contractual relationships, (2) committed industrial espionage and
misappropriation, (3) trespassed on AFC's business premises, (4) converted
certain property of AFC, (5) committed unfair competition, and (6) committed
acts in violation of the Racketeering Influenced Corrupt Organization Act. The
Company believes that it has valid and substantial claims against all of the
defendants. The Company intends to vigorously defend all of the defendants'
counterclaims, and further believes that it has valid defense to all of the
counterclaims.

On April 10, 1995, the Company filed a lawsuit against Next Level Communications
("NLC") and two former Company employees, alleging





                                Page 8 0f 20
<PAGE>   9
breach of contract and the misuse of Company trade secrets. The Company is
seeking an injunction prohibiting NLC and the former employees from continued
use of Company trade secrets and opportunities. On March 28, 1996, the Company
received a favorable jury verdict in the amount of $369.2 million in damages.
The Court is yet to enter a judgment or rule on the issue of injunctive relief.
Once the Court enters a judgment, NLC will have 30 days to appeal the award.

On February 14, 1996, the Company joined Bell Atlantic in bringing an antitrust
action against AT&T Corporation ("AT&T") and Lucent Technologies, Inc.
("Lucent") alleging the use of monopoly power in the central office switch
market as part of a scheme to gain an unfair competitive advantage in the
remote digital terminal market. The Company is seeking to compel AT&T and
Lucent to open up the interfaces to the central office switch so that any
manufacturer will have the ability to compete with applications, software,
features, and services, and will more rapidly deliver to its customers the
enhanced functionality that they have come to expect.

The Company is also party to other routine legal proceedings incidental to its
business.

The Company does not believe the ultimate resolution of the above litigation
will have a material adverse effect on its consolidated financial position.

COMMON STOCK

At the April 25, 1996 Annual Shareholders' Meeting, the shareholders approved
certain amendments and an increase of 6 million shares of common stock subject
to the DSC Communications Corporation 1993 Employee Stock Option and Securities
Award Plan.

STOCK RIGHTS

On April 25, 1996, the Board of Directors declared a dividend of one preferred
stock purchase right on each outstanding share of the Company's common stock.
The dividend is payable on May 22, 1996 to shareholders of record on that date,
the same date the existing stock rights expire. The rights become exercisable
only on the close of business ten days following a public announcement that a
person or group has acquired 15% or more of the outstanding shares of common
stock of the Company or a public announcement or commencement of a tender offer
or exchange offer which would result in the offeror's acquiring 15% or more of
the outstanding shares of common stock of the Company. Once exercisable, each
right would entitle a holder to buy 1/1000 of a share of the Company's Series B
Junior Participating Preferred Stock at an exercise price of $175.00. The
Company may





                                Page 9 0f 20
<PAGE>   10
redeem the rights for $0.01 per right prior to the rights becoming exercisable,
and the rights expire on April 25, 2006.

Item 2.      Management's Discussion and Analysis of Financial Condition
             and Results of Operations.

"SAFE HARBOR" STATEMENT UNDER THE PRIVATE SECURITIES LITIGATION REFORM ACT OF
1995

With the exception of historical information, the matters discussed or
incorporated by reference in this Quarterly Report on Form 10-Q are
forward-looking statements that involve risks and uncertainties including, but
not limited to, economic conditions, product demand and industry capacity,
competitive products and pricing, manufacturing efficiencies, new product
development, ability to enforce patents, availability of raw materials and
critical manufacturing equipment, new plant startups, the regulatory and trade
environment, and other risks indicated in filings with the Securities and
Exchange Commission.

Results of Operations

For the three months ended March 31, 1996, the Company reported revenue of
$307.9 million and net income of $11.5 million, or $0.10 per share, compared to
revenue of $318.0 million and net income of $41.9 million, or $0.36 per share,
for the three months ended March 31, 1995.

Compared to the same period last year, the revenue decline in the first quarter
of 1996 was primarily due to a slower European transmission business and
reduced deliveries of the Company's wireless switching products, offset
partially by increased deliveries of the Company's access products. Gross
profit as a percentage of revenue was 42% for the 1996 first quarter compared
to 50% in the same period of 1995. This decline was due primarily to a change
in product mix, including reduced software content, and decreased business
volumes. Certain of the Company's products, including software, typically
produce gross margin content greater than other Company products. As a result,
the Company's gross margin percentage in future periods could vary
significantly due to changes in the relative mix of product deliveries, as
occurred in the first quarter of 1996 compared to the first quarter of 1995.

Research and product development expenses increased to $53.1 million, or 17% of
revenue, for the three month period ended March 31, 1996 compared to $46.9
million, or 15% of revenue, for the three month period ended March 31, 1995.
The growth in research and development expenses reflects increased costs
related to the Company's on-going development of new products and enhancements
to existing products across all strategic product lines. Selling, general and
administrative expenses increased $9.7 million in the first three months of
1996 to $55.8 million or 18% of revenue from 14% for the same period in 1995.
This expense growth included expanded





                                Page 11 0f 20
<PAGE>   12
international selling activities and higher legal costs. The Company is
actively pursuing claims related to its intellectual property rights and, as
this litigation progresses, legal expenses may continue to increase. See
"Litigation" under "Commitment and Contingencies" in Notes to Condensed
Consolidated Financial Statements for further discussion.

DSC Communications A/S incurred an operating loss in the first quarter of 1996
due primarily to the delayed introduction of a new generation of optical
transmission equipment. While it is anticipated that this development will be
completed and product deliveries will begin over the next several months,
future near-term profitability of the Company's Denmark subsidiary is dependent
upon the successful completion and market acceptance of these products.

Both interest expense and interest income have increased in the three month
period ended March 31, 1996 compared to the three month period ended March 31,
1995 due primarily to the $225 million loan entered into in April 1995 which
bears interest at 9%. The majority of the proceeds from this loan have been
invested in short-term investments. Interest expense has also increased as a
result of borrowings under several foreign subsidiary borrowing arrangements
entered into during the second half of 1995.

The Company's estimated effective income tax rate was 38% for the three month
period ended March 31, 1996 compared to 35% for the same period in 1995. This
increase in the effective income tax rate is due primarily to the full
utilization of net operating loss and tax credit carryforwards in 1995 and an
expected increase in foreign taxes in 1996. See "Income Tax Expense" in Notes
to Condensed Consolidated Financial Statements for further information.

The Company has certain forward exchange contracts which were entered into
based upon anticipated future business transactions. Although these forward
contracts totaled only $2.9 million at March 31, 1996, future earnings could be
affected by the Company's practice of entering into these types of forwards as
forward contracts related to anticipated transactions are marked-to-market each
period.

The Company's future quarterly and annual operating results may be affected by
a number of factors, including the timing and ultimate receipt of orders from
certain customers which continue to constitute a large portion of the Company's
revenue; the successful enhancement of existing products; introduction and
market acceptance of new products on a timely basis; mix of products sold;
product costs; manufacturing lead times; significant fluctuations in foreign
currency exchange rates; and changes in general worldwide economic conditions,
any of which could have an adverse impact on operations.





                                Page 12 0f 20
<PAGE>   13
Financial Condition and Liquidity

The Company's cash and cash equivalents at March 31, 1996 were $228.4 million
compared to $258.6 million at December 31, 1995, and marketable securities were
$303.2 million at March 31, 1996 compared to $310.7 million at December 31,
1995.

Cash used for operating activities of $4.5 million was primarily the result of
lower earnings, increased inventories to support existing customer backlog and
expected additional customer requirements, and a reduction in current payables.

Investing activities during the three months ended March 31, 1996 included
additions to property and equipment of $33.9 million. The Company's expected
future domestic and international business growth will require additional
capital expenditures. The timing and extent of additional capital requirements
are dependent on future business growth. However, the Company anticipates that
capital expenditures for 1996 could be in the range of approximately $150
million.

Two of the Company's foreign subsidiaries have several short-term credit
arrangements providing for borrowings up to $106.0 million, of which $92.2 were
outstanding at March 31, 1996. These arrangements are being used to fund
facilities expansion and working capital requirements and are repayable in
various foreign currencies. The Company expects to refinance approximately $50
million of the amount outstanding under these agreements with a long-term
facility during the next several months.

As discussed in "Credit Agreements and Short-Term Borrowings" in Notes to
Condensed Consolidated Financial Statements, the Company replaced its existing
domestic credit facility with a new, unsecured $160.0 million revolving credit
agreement in early May 1996. No borrowings were outstanding under the credit
facilities existing at March 31, 1996. Outstanding letters of credit, which
totaled $30.2 million at March 31, 1996, reduce the amount of available
borrowings.

The Company is party to certain litigation, as disclosed in "Litigation" under
"Commitment and Contingencies" in Notes to Condensed Consolidated Financial
Statements, the outcome of which the Company believes will not have a material
adverse effect on its consolidated financial position.

The Company believes that its existing cash and marketable securities and
available credit facilities will be adequate to support the Company's financial
resource needs, including working capital requirements, capital expenditures,
operating lease obligations, and debt payments. In order to be competitive in
the future, the Company believes that it will become increasingly necessary to
offer financing





                                Page 13 0f 20
<PAGE>   14
alternatives to both domestic and international customers. To the extent such
financing becomes significant, additional borrowings could become necessary.

PART II - OTHER INFORMATION

Item 1. Legal Proceedings.

Litigation

On January 26, 1994, C.L. Grimes, a stockholder of the Company, filed a
derivative suit in Delaware Chancery Court, purportedly on behalf of the
Company as the real party in interest and as a stockholder of the Company,
seeking a declaration that the Employment Agreement of James L. Donald, his
Executive Income Continuation Plan, and the 1990 Long- Term Incentive
Compensation Plan as it applies to Mr. Donald and all other benefits of Mr.
Donald, including previously granted Company stock options, are null and void.
The defendants in the suit are Mr. Donald, all current non-employee directors,
and two former directors of the Company. The Company itself is a nominal
defendant. The plaintiff contends that Mr. Donald's employment contract
contains an improper delegation of Board of Directors' authority to Mr. Donald
and excess payments. The suit also contends that the salary and benefits
established for Mr. Donald pursuant to the Donald agreements referred to above
and approved by the Company's Board of Directors are excessive and constitute a
diversion and waste of corporate assets. The suit seeks an injunction
restraining Mr. Donald from exercising any stock options, taking any action to
implement any of the Donald agreements, or declaring a constructive termination
of his employment, and also seeks unspecified damages against the defendants
and Grimes' legal fees. On June 1, 1994, the plaintiff filed an amended
complaint in which he restated his existing claims and added a new claim
contending that the Company's 1994 proxy statement was misleading in its
description of the 1994 Long-Term Incentive Compensation Plan ("LTIP"). On this
new claim, the plaintiff seeks a decree that the 1994 proxy statement insofar
as it relates to the 1994 LTIP and the actions taken pursuant to the proxy
statement with respect to the 1994 LTIP are null and void, and seeks to enjoin
the Company from implementing the 1994 LTIP.

On June 15, 1994, all defendants filed motions to dismiss all of the
plaintiff's claims, with the exception of the claim relating to the Company's
1994 proxy statement. On January 11, 1995, the Delaware Chancery Court granted
defendants' motions to dismiss. The plaintiff later filed a motion seeking
entry of a final judgment of dismissal so that he would be free to pursue an
immediate appeal of the Court's decision. In response, the Court directed entry
of a final judgment and certified the dismissed claims for appellate review. On
March 6, 1995, the plaintiff filed an appeal of the dismissed claims to the
Delaware Supreme Court. On April 11, 1996, the Delaware Supreme Court affirmed
the Chancery Court's previous decision and found in favor of the Company. The
plaintiff has the option to seek further discretionary review by the United
States Supreme Court.

The following matters were voted on by the stockholders:

1.   Election of three Class III Directors. James L. Donald, Robert S. Folsom,
     and James M. Nolan were elected to the Board of Directors as Class III
     Directors for terms extending through the 1999 Annual Meeting of
     Stockholders. The vote was 95,173,628 shares in favor of James L. Donald,
     with 4,787,411 votes withheld, 95,261,676 shares in favor of Robert S.
     Folsom, with 4,699,363 votes withheld and 95,186,089 shares in favor of

2.   Approval of an increase of 6,000,000 shares of Common Stock subject to the
     DSC Communications Corporation 1993 Employee Stock Option and Securities
     Award Plan. Under the terms of the 1993 Employee Stock Option and
     Securities Award Plan, as amended, the Company may grant Plan Awards with
     respect to an aggregate of 4,000,000 shares of Common Stock. On October
     30, 1995, the Company's Board of Directors and Compensation Committee
     amended the 1993 Plan to add an additional 6,000,000 shares of Common
     Stock to the 1993 Plan, subject to stockholder approval. At the 1996
     Annual Meeting of Stockholders, the Company's stockholders approved the
     increase in the shares. The vote was 65,267,863 shares in favor,
     13,874,456 shares against, 392,268 shares abstaining and 20,426,452 broker
     non-votes.

3.   Approval of amendments to the DSC Communications Corporation 1993 Employee
     Stock Option and Securities Award Plan. Subject to stockholder approval,
     the Company's Board of Directors and Compensation Committee approved
     certain amendments to the 1993 Employee Stock Option and Securities Award
     Plan. The 1993 Plan, as amended, is set forth in its entirety in Exhibit A
     to the Company's Definitive Proxy Statement filed in connection with the
     1996 Annual Meeting of Stockholders. At the 1996 Annual Meeting of
     Stockholders, the Company's stockholders approved the amendments. The vote
     was 85,945,279 shares in favor, 9,668,223 shares against, 471,800 shares
     abstaining and 3,875,737 broker non-votes.

Company, through a Financial Officer, shall give Administrative Lender at least
three Business Days' irrevocable written notice (in the form of Advance
Request), or irrevocable telephonic notice followed immediately by written

notice so given), of its intention to borrow a Eurocurrency Advance hereunder.
Notice shall be given to Administrative Lender prior to 11:00 a.m. in order for
such Business Day to count toward the minimum number of Business Days required.
Eurocurrency Advances shall in all cases be subject to availability and to
Article VIII.  Each Advance Request shall specify the requested funding date,
which shall be a Business Day, the Eurocurrency in which the Advance will be
funded, the amount of the proposed aggregate Eurocurrency Advances, and the

Payment Date, each LIBOR Advance and Eurocurrency Advance shall, subject to the

Failure of Company to give any notice in accordance with Section 2.02(d) with
respect to a LIBOR Advance or Eurocurrency Advance (or if on the applicable
Payment Date a Default shall exist) shall result in a repayment of any such
existing LIBOR Advance or Eurocurrency Advance on the applicable Payment Date
by an Advance which is a Base Rate Advance.  Such a LIBOR Advance or
Eurocurrency Advance must be repaid in full and may not be reborrowed.  Each
Lender shall, not later than 2:00 p.m. on the date of any Advance that is not a
Refinancing Advance, deliver to Administrative Lender, at its address specified
in Section 10.01, an amount equal to such Lender's Specified Percentage of such

Lender shall, subject to satisfaction of the conditions set forth in Article
III, disburse the amounts made available to Administrative Lender by Lenders by
(i) transferring such amounts by wire transfer pursuant to Company's
instructions, or (ii) in the absence of such instructions, crediting such

         (a)     On Base Rate Advances.  Company shall pay interest on the
unpaid principal amount of the Base Rate Advances outstanding from time to

arrears on the applicable Payment Date and on the Maturity Date; provided,

Advance shall be computed on the basis of a 360-day year (except in the case of
Advances denominated in Pounds, on the basis of a 365 or 366-day year, as
appropriate), for the actual number of days elapsed, and shall be payable in
arrears on the applicable Payment Date and on the Maturity Date; provided,

three months, interest shall also be due and payable in arrears on the 90th day
of such Interest Period.

         (d)     Interest if No Notice of Selection of Interest Rate Basis.  If
Company fails to give Administrative Lender timely notice of its selection of a
LIBOR Advance or Eurocurrency Advance or an Interest Period for a LIBOR Advance
or a Eurocurrency Advance, or if for any reason a determination of a LIBOR
Basis or a Eurocurrency Basis for any Advance is not timely concluded due to
the fault of Company in the reasonable opinion of Determining Lenders, (i) the
Base Rate shall apply to the applicable Advance and (ii) the Lenders shall have
no obligation to fund such Eurocurrency Advance.

         (e)     Interest After an Event of Default.  (i) Commencing thirty
days after an Event of Default (other than an Event of Default specified in
Section 6.01(g) or (h)) and during any continuance thereof, at the option of
Determining Lenders, and (ii) after an Event of Default specified in Section
6.01(g) or (h) and during any continuance thereof, automatically and without
any action by Administrative Lender, or any Lender, the Obligations which (A)

(1) the Highest Lawful Rate and (2) the Base Rate, Eurocurrency Basis or LIBOR
Basis, as applicable, plus two percent, and (B) do not otherwise bear interest
shall bear interest at a rate per annum equal to the Default Rate.  Such
interest shall be payable on the earlier of demand or the Maturity Date, and
shall accrue until the earlier of (i) waiver or cure (to the reasonable
satisfaction of Determining Lenders) of the applicable Event of Default, (ii)
agreement by Lenders to rescind the charging of interest at the Default Rate,
or (iii) payment in full of the Obligations.  Lenders shall not be required to
(i) accelerate the maturity of the Advances, (ii) exercise any other rights or
remedies under the Loan Documents, or (iii) give notice to any Loan Party of
the decision to charge interest at the Default Rate.  Lenders will undertake to
notify Company, after the effective date, of the decision to charge interest at
the Default Rate.

         Consolidated Excess Cash Flow Ratio.  Any such increase or reduction
         in such fee shall be effective as of the day following the date of
         receipt of the financial statements required pursuant to Section
         5.01(a) or (b), as appropriate.  If such financial statements are not
         received by the day following the date required, the fee payable in
         respect of the Commitment shall be determined as if the Consolidated
         Funded Debt to Consolidated Excess Cash Flow Ratio is greater than or
         equal to 2.00 to 1 until such time as such financial statements are
         received.  Notwithstanding anything herein to the contrary, the
         commitment fee from and including the Agreement Date to but not
         including the day following receipt of Company's March 31, 1996,
         financial statements shall be .20%.

         (b)     Participation Fee.  Subject to Section 10.09, Company shall
pay to Administrative Lender, for the ratable account of Lenders, a one-time
participation fee of 0.050% based on the amount of each Lender's Specified
Percentage of the Commitment.  Such fee shall be payable on the Agreement Date,
and shall be fully-earned when due and, subject to Section 10.09, nonrefundable
when paid.

         (c)     Other Fees.  Subject to Section 10.09, Company shall pay to
Administrative Lender and Arranger, for their respective accounts and not the
account of Lenders, the fees provided for in the letter agreement ("Fee
Letter"), dated as of September 25, 1995, among Company, Administrative Lender
and Arranger on the date and in the amounts specified therein.

         2.05.   Prepayment.

         (a)     Voluntary Prepayments.  The principal amount of any Base Rate
Advance may be voluntarily prepaid in full or in part at any time without
penalty, upon telephonic notice (to be promptly followed by written notice) by
an Authorized Signatory to Administrative Lender prior to 10:00 a.m. on the
date of such prepayment.  Subject to Section 2.09, the principal amount of any
LIBOR Advances may be voluntarily prepaid in full or in part at any time
without penalty upon three Business Days' prior telephonic notice (to be
promptly followed by written





                                     - 27 -
<PAGE>   34
notice) by an Authorized Signatory to Administrative Lender.  Subject to
Section 2.09, the principal amount of any Eurocurrency Advances may be
voluntarily prepaid in full or in part at any time without penalty upon five
Business Days' prior telephonic notice (to be promptly followed by written
notice) by an Authorized Signatory to Administrative Lender.

         (b)     Mandatory Prepayment.  On or before the date of any reduction
of the Commitment, Company shall prepay outstanding Advances in an amount
necessary to cause the sum of outstanding Advances and Reimbursement
Obligations to be an amount not greater than the Commitment as so reduced
pursuant to Section 2.06.  Company shall first prepay all Base Rate Advances,
second prepay all LIBOR Advances and third prepay all Eurocurrency Advances.
If on any date the sum of outstanding Advances and Reimbursement Obligations is
greater than the Commitment (for any reason, including any determination by
Administrative Lender pursuant to Section 1.04), Company shall repay
outstanding Advances in an amount necessary to cause the sum of outstanding
Advances and Reimbursement Obligations to be an amount not greater than the
Commitment; provided, however, if (i) no Default or Event of Default shall
exist and (ii) the only reason that the sum of outstanding Advances and
Reimbursement Obligations exceeds the Commitment is as a result of a change in
the Eurocurrency equivalents of Dollars (the "Eurocurrency Equivalent Excess"),
Company shall not be obligated to repay the Eurocurrency Equivalent Excess
until the end of the Interest Period of the Eurocurrency Advance or Advances
that caused the Eurocurrency Equivalent Excess so long as (i) the Eurocurrency
Equivalent Excess does not exceed 10% of the Commitment or (ii) if the
Eurocurrency Equivalent Excess does exceed 10% of the Commitment, Company has
provided Administrative Lender with cash collateral (and such agreements and
documents which in the reasonable judgment of Administrative Lender are
necessary to perfect a Lien in such cash collateral) in an amount equal to the
amount by which the Eurocurrency Equivalent Excess exceeds 10% of the
Commitment.  To the extent that any prepayment (whether mandatory or voluntary)
requires that a LIBOR Advance or Eurocurrency Advance be repaid on a date other
than the last day of its Interest Period, Company shall reimburse each Lender
in accordance with Section 2.09.

         (c)     Prepayments, Generally.  Any prepayment of an Advance shall be
accompanied by interest accrued on the principal amount being prepaid.  Any
voluntary partial prepayment of a Base Rate Advance shall be in a principal
amount of $1,000,000 or integral multiples of $100,000 in excess thereof.  Any
voluntary partial prepayment of a LIBOR Advance shall be in a principal amount
of $5,000,000 or integral multiples of $1,000,000 in excess thereof or in such
other amount to the extent that the prepayment is with respect to a Refinancing
Advance that included accrued interest.  Any voluntary partial prepayment of a
Eurocurrency Advance shall be in a principal amount which is at least the
Eurocurrency equivalent (as determined by Administrative Lender) of $1,000,000
or integral multiples of the Eurocurrency equivalent of $500,000 in excess
thereof or in such other amount to the extent that the prepayment is with
respect to a Refinancing Advance that included accrued interest.  Prepayment of
LIBOR Advance and Eurocurrency Advance shall be applied to LIBOR Advance and
Eurocurrency Advances according to the respective Sharing Ratio of Lenders.
Prepayments of Base Rate





                                     - 28 -
<PAGE>   35
Advances shall be applied to the outstanding Base Rate Advances in accordance
with the Specified Percentage of Lenders.

         2.06.   Reduction of Commitment.

         (a)     Voluntary Reduction.  Company shall have the right, upon not
less than ten Business Days' notice (provided only three Business Days' notice
shall be required for a termination in whole of the Commitment) by an
Authorized Signatory to Administrative Lender (if telephonic, to be confirmed
by telecopy or in writing on or before the date of reduction or termination),
which shall promptly notify Lenders, to reduce the Commitment in part or
terminate the Commitment in whole.  Each partial termination shall be in an
aggregate amount which is at least $10,000,000 and which is an integral
multiple of $10,000,000, and no voluntary reduction in the Commitment shall
cause any LIBOR Advance or Eurocurrency Advance to be repaid prior to the last
day of its Interest Period unless Company concurrently reimburses Lenders in
accordance with Section 2.09.

         (b)     Mandatory Reduction.  On the Maturity Date, the Commitment
(other than the obligation of Issuing Bank to honor drawings against Letters of
Credit outstanding on the Maturity Date) shall automatically reduce to zero.

         (c)     General Requirements.  Upon any reduction of the Commitment
pursuant to this Section 2.06, Company shall immediately make a repayment of
applicable Advances in accordance with Section 2.05(b).  Company shall
reimburse each Lender for any loss or out-of-pocket expense incurred by each
Lender in connection with any such payment, as set forth in Section 2.09 to the
extent applicable.  Company shall not have any right to rescind any termination
or reduction.  Once reduced or terminated, the Commitment may not be increased
or reinstated.

         2.07.   Non-Receipt of Funds by Administrative Lender.  Unless
Administrative Lender shall have been notified by a Lender prior to the date of
any proposed Advance (which notice shall be effective upon receipt) that such
Lender does not intend to make the proceeds of such Advance available to
Administrative Lender, Administrative Lender may assume that such Lender has
made such proceeds available to Administrative Lender, on such date, and
Administrative Lender may in reliance upon such assumption (but shall not be
required to) make available to Company a corresponding amount.  If such
corresponding amount is not in fact made available to Administrative Lender by
such Lender, Company and such Lender severally agree to repay to Administrative
Lender forthwith on demand such corresponding amount together with interest
thereon in respect of each day during the period commencing on the date such
amount was available to Company and ending on (but excluding) the date
Administrative Lender receives such amount from Lender or Company at a per
annum rate equal to the lesser of (a) the Highest Lawful Rate and (b) (i) in
the case of such Lender, the Federal Funds Effective Rate and (ii) in the case
of Company, the interest rate applicable to such Advance; provided, however, no
provision of this Agreement or any other Loan Document shall require Company to
pay interest on such amount except as provided in this Section 2.07.  If such
Lender





                                     - 29 -
<PAGE>   36
shall repay to Administrative Lender, such corresponding amount, such amount
shall constitute such Lender's Advance for purposes of this Agreement.  No
Lender shall be liable for any other Lender's failure to fund an Advance
hereunder.

         2.08.   Payment of Principal of Advances.  Company agrees to pay the
principal amount of its respective Advances in the currency borrowed to
Administrative Lender for the account of Lenders as follows:

         (a)     Base Rate Advances.  The unpaid principal amount of the Base
Rate Advances shall be due and payable on the Maturity Date.

         (b)     LIBOR Advances and Eurocurrency Advances.  The principal
amount of each LIBOR Advance and each Eurocurrency Advance hereunder shall be
due and payable on its Payment Date, which (subject to the other provisions of
this Agreement) principal payment may be made by means of a Refinancing
Advance.

         (c)     Commitment Reduction.  On the date of any reduction of the
Commitment pursuant to Section 2.06, including the Maturity Date, the aggregate
amount of the Advances outstanding on such date of reduction in excess of the
Commitment as reduced minus all outstanding Reimbursement Obligations shall be
due and payable, which principal payment may not be made by means of
Refinancing Advances.

         (d)     Maturity Date.  To the extent not otherwise required to be
paid earlier as provided herein, the principal amount of the Advances, all
accrued interest and fees thereon, and all other Obligations related thereto,
shall be due and payable in full on the Maturity Date.

         2.09.   Reimbursement.  Whenever any Lender shall sustain or incur any
losses or reasonable out-of-pocket expenses in connection with (a) failure by
Company to borrow any LIBOR Advance or Eurocurrency Advance after having given
notice of its intention to borrow in accordance with Section 2.02 (whether by
reason of Company's election not to proceed or the non-fulfillment of any of
the conditions set forth in Article III), or (b) any payment or prepayment for
any reason of any LIBOR Advance or Eurocurrency Advance in whole or in part
(including a prepayment pursuant to Sections 2.05(c) and 8.03(b)), Company
shall pay to any such Lender, upon its demand, subject to Section 10.09, an
amount sufficient to compensate such Lender for all such losses and
out-of-pocket expenses, including, but not limited to, any loss or reasonable
expense sustained or incurred or to be sustained or incurred in liquidating or
employing deposits from third parties acquired to effect or maintain such LIBOR
Advance or Eurocurrency Advance or any part thereof as a LIBOR Advance or
Eurocurrency Advance.  Such loss shall equal an amount equal to the excess, if
any, as reasonably determined by each Lender of (i) its cost of obtaining the
funds for the LIBOR Advance or Eurocurrency Advance being paid, prepaid or
converted pursuant to Article VIII or not borrowed (based on the LIBOR Basis,
Eurocurrency Basis applicable thereto) for the period from the date of such
payment, prepayment or conversion or failure to borrow to the last day of the
Interest Period for such LIBOR Advance or Eurocurrency Advance (or, in the case
of a failure to borrow, the Interest





                                     - 30 -
<PAGE>   37
Period for such LIBOR Advance or Eurocurrency Advance which would have
commenced on the date of such failure to borrow) over (ii) the amount of
interest (as reasonably determined by such Lender) that could be realized by
such Lender in reemploying during such period the funds so paid, prepaid or
converted or not borrowed in an instrument or investment of substantially
similar yield to such LIBOR Advance or Eurocurrency Advance.  Such Lender's
good faith determination of the amount of such losses or out-of-pocket
expenses, calculated in its usual fashion, absent demonstrable error, shall be
binding and conclusive.  Such Lender shall provide a certificate setting forth
the amount to be paid to it by Company hereunder and calculations therefor.
Company's obligation pursuant to this Section 2.09 is not dependent upon any
Lender's actual reinvestment or method of reinvestment of the prepaid LIBOR
Advance or Eurocurrency Advance.

         2.10.   Manner of Payment.

         (a)     Each payment (including prepayments) by Company of the
principal of or interest on the Advances, fees, and any other amount owed under
this Agreement or any other Loan Document shall be made with respect to
principal, interest, fees, and other amounts due to Administrative Lender or
any Lenders, not later than 12:00 noon on the date specified for payment under
this Agreement to Administrative Lender at its address specified in Section
10.01 or Schedule 1.01(d), in the currency borrowed constituting immediately
available funds.

         (b)     If any payment under this Agreement or any other Loan Document
shall be specified to be made upon a day which is not a Business Day, it shall
be made on the next succeeding day which is a Business Day, unless such
Business Day falls in another calendar month, in which case payment shall be
made on the preceding Business Day.  Any extension of time shall in such case
be included in computing interest and fees, if any, in connection with such
payment.

         (c)     Company shall pay (i) in respect of the Advances made to
Company, principal, interest, and fees and (ii) all other fees and amounts due
under the Loan Documents without deduction for set-off or counterclaim or any
deduction whatsoever.

         (d)     If some but less than all amounts due from Company are
received by Administrative Lender, Administrative Lender shall apply such
amounts in the following order of priority:  (i) to the payment of
Administrative Lender's expenses incurred on behalf of Lenders then due and
payable, if any; (ii) to the payment of all other fees then due and payable;
(iii) to the payment of interest then due and payable on the Advances; (iv) to
the payment of all other amounts not otherwise referred to in this clause (d)
then due and payable under the Loan Documents; and (v) to the payment of
principal then due and payable on the Advances owed to each Lender in
accordance with its Sharing Ratio.

         2.11.   Lending Offices.  Each Lender's initial Lending Office for
Base Rate Advances, LIBOR Advances and Eurocurrency Advances, as appropriate,
is set forth opposite its name in Schedule 2.11.  Each Lender shall have the
right at any time and from time to time to designate





                                     - 31 -
<PAGE>   38
a different office of itself or of any Affiliate as such Lender's Lending
Office for Base Rate Advances, LIBOR Advances and Eurocurrency Advances, as
appropriate, and to transfer any outstanding LIBOR Advance, Base Advance or
Eurocurrency Advance to such Lending Office.  No such designation or transfer
shall result in any liability on the part of Company for increased costs or
expenses resulting solely from such designation or transfer (except any such
transfer which is made by a Lender pursuant to Section 8.02 or 8.03, or
otherwise for the purpose of complying with Applicable Law).  Increased costs
for expenses resulting from a change in Law occurring subsequent to any such
designation or transfer shall be deemed not to result solely from such
designation or transfer.

         2.12.   Booking Advances.  Any Lender may make, carry or transfer
Advances at, to or for the account of any of its branch offices or the office
of any Affiliate.

         2.13.   Sharing of Payments.  Any Lender obtaining a payment (whether
voluntary or involuntary, due to the exercise of any right of set-off, or
otherwise) on account of its Advances in excess of its Specified Percentage of
all payments made by Company with respect to Advances shall purchase from each
other Lender such participation in the Advances made by such other Lender as
shall be necessary to cause such purchasing Lender to share the excess payment
pro rata according to Specified Percentages with each other Lender; provided,
however, that if all or any portion of such excess payment is thereafter
recovered from such purchasing Lender, the purchase shall be rescinded and the
purchase price restored to the extent of such recovery, but without interest.
Company agrees that any Lender so purchasing a participation from another
Lender pursuant to this Section 2.13, to the fullest extent permitted by Law,
may exercise all its rights of payment (including the right of set-off) with
respect to such participation as fully as if such Lender were the direct
creditor of Company in the amount of such participation.

         2.14.   Calculation of LIBOR Rate and Eurocurrency Rate.  The
provisions of this Agreement relating to calculation of the LIBOR Rate and
Eurocurrency Rate are included only for the purpose of determining the rate of
interest or other amounts to be paid hereunder that are based upon such rate,
it being understood that each Lender shall be entitled to fund and maintain its
funding of all or any part of a LIBOR Advance and Eurocurrency Advance as it
sees fit.

         2.15.   Taxes.

         (a)     If each Lender has complied with the provisions of Section
2.15(b), all payments by Company for the account of such Lender of principal
of, and interest on, the Advances and all other amounts payable hereunder shall
be made free and clear of and without deduction for any present or future
income, excise, stamp, or franchise taxes and other taxes, fees, duties,
withholdings, or other charges of any nature whatsoever imposed by any taxing
authority, but excluding franchise taxes and taxes imposed on or measured by
any Lender's net income or receipts (such non-excluded items being called
"Non-Excluded Taxes").  In the event that any





                                     - 32 -
<PAGE>   39
withholding or deduction from any payment to be made by Company hereunder is
required in respect of any Non-Excluded Taxes pursuant to any Applicable Law,
then Company will:

                 (i)      pay directly to the relevant authority the full
         amount required to be so withheld or deducted;

                 (ii)     promptly forward to Administrative Lender an official
         receipt or other documentation satisfactory to Administrative Lender
         evidencing such payment; and

                 (iii)    pay to Administrative Lender for the account of
         Lenders such additional amount or amounts as is necessary to ensure
         that the net amount actually received by each Lender will equal the
         full amount such Lender would have received had no such withholding or
         deduction been required.

Moreover, if any Non-Excluded Taxes are directly asserted against
Administrative Lender or any Lender with respect to any payment received by
Administrative Lender or such Lender hereunder, Administrative Lender or such
Lender may pay such Non-Excluded Taxes and Company will promptly pay such
additional amounts (including any penalties, interest or expenses) as is
necessary in order that the net amount received by such Person after the
payment of such Non-Excluded Taxes (including any Non-Excluded Taxes on such
additional amount) shall equal the amount such Person would have received had
no such Non-Excluded Taxes been asserted.

         If any Company fails to pay any Non-Excluded Taxes when due to the
appropriate taxing authority or fails to remit to Administrative Lender, for
the account of the respective Lenders, the required receipts or other required
documentary evidence, Company shall indemnify Administrative Lender and,
without duplication, Lenders for any incremental Non-Excluded Taxes, interest
or penalties that may become payable by Administrative Lender or, without
duplication, any Lender as a result of any such failure.  For purposes of this
Section 2.15, a distribution hereunder by Administrative Lender or, without
duplication, any Lender to or for the account of any Lender shall be deemed a
payment by Company.

         (b)     Each Lender shall deliver to each of Company and
Administrative Lender either (i) a letter or other written certification in
duplicate stating that it is organized under the Laws of the United States of
America or a state thereof and containing its employer identification number,
address of its place of business in the United States of America and the
signature and official title of the signing partner or corporate officer (a
"Letter of Domestic Organization") or (ii) if it is not a "United States
person" within the meaning of Section 7701(a)(30) of the Code (a "Foreign
Lender") (x) two properly completed and executed copies of United States
Internal Revenue Service Form 4224 or Form 1001 or other successor applicable
form, certificate or document prescribed by the Internal Revenue Service
certifying as to such Foreign Lender's entitlement to an exemption from or
reduced rate of United States withholding under an applicable statute or tax
treaty with respect to payments to be made to such Foreign Lender hereunder (a
"Certificate of Exemption") or (y) a letter (in duplicate) from such Foreign
Lender





                                     - 33 -
<PAGE>   40
stating that it is not entitled to any such exemption or reduced rate (a
"Letter of Non-Exemption").  Each initial Lender shall provide such a Letter of
Domestic Organization or a Certificate of Exemption or a Letter of
Non-Exemption on or before the Effective Date; each Lender that becomes a
Lender after the Effective Date shall provide a Letter of Domestic
Organization, a Certificate of Exemption or a Letter of Non-Exemption on the
date such Lender becomes a Lender and each Lender shall provide additional
Letters of Domestic Organization, Certificates of Exemption or Letters of Non-
Exemption from time to time thereafter if requested by Company or
Administrative Lender or required because, as a result of a Law or a change in
Law, or a change in circumstances, the expiration of a previously delivered
letter or certificate, or otherwise, a previously delivered letter or
certificate becomes incomplete, incorrect or ineffective in any material
respect; provided, however, that each initial Lender (other than ABN AMRO Bank
N.V. Houston Agency and Commerzbank Aktiengesellschaft, Atlanta Agency)
executing this Agreement certifies that it is organized under the Laws of the
United States of America or a state thereof.  Unless Company and Administrative
Lender have received from each Lender a Certificate of Exemption or Letter of
Domestic Organization when and as required pursuant to the preceding sentence,
the accuracy of which shall be reasonably satisfactory to Company and
Administrative Lender, Company and Administrative Lender shall be entitled to
withhold taxes from all payments to such Lender at the statutory rate
applicable to amounts to be paid hereunder to such Lender.  If Company and
Administrative Lender have received from any Foreign Lender a Certificate of
Exemption when and as required by this Section 2.15(b), the accuracy of which
shall be reasonably satisfactory to Company and Administrative Lender,
certifying as to such Foreign Lender's entitlement to a reduced rate of
withholding tax, Company and Administrative Lender shall withhold taxes from
all payments to such Foreign Lender at the rate specified in such certificate.
Any reference to any Lender in this Section 2.15 shall be deemed to refer to
and include Issuing Bank.

         2.16.   Letters of Credit.

         (a)      The Letter of Credit Facility.  Company may request Issuing
Bank, on the terms and conditions hereinafter set forth, to issue, and Issuing
Bank shall, if so requested, issue, Letters of Credit for the account of
Company from time to time on any Business Day from the Effective Date until the
Maturity Date in an aggregate maximum amount (assuming compliance with all
conditions to drawing) not to exceed at any time outstanding (A) the Commitment
minus (B) the aggregate principal amount of Advances then outstanding (the
"Letter of Credit Facility").  Letters of Credit may be issued in Dollars,
Eurocurrencies, or, subject to the provisions hereof, other currencies which
are determined by Issuing Bank to be available.  No Letter of Credit
denominated in Dollars or Eurocurrencies shall have an expiry date (including
all rights of renewal) later than the Maturity Date.  No Letter of Credit
denominated in a currency other than Dollars or Eurocurrencies shall have an
expiry date (including all rights of renewal) later than a date reasonably
determined by Issuing Bank; provided, however, in no event shall such expiry
date (including all rights of renewal) be later than the Maturity Date.
Immediately upon the issuance of each Letter of Credit (or upon satisfaction of
the conditions set forth in Section 3.01 and 3.02, with respect to the Existing
Letters of Credit), Issuing Bank shall be deemed to have sold and transferred
to each Lender, and each Lender shall be deemed





                                     - 34 -
<PAGE>   41
to have purchased and received from Issuing Bank, in each case irrevocably and
without any further action by any party, an undivided interest and
participation in such Letter of Credit, each drawing thereunder and the
obligations of Company under this Agreement in respect thereof in an amount
equal to the product of such Lender's Specified Percentage times the maximum
amount in Dollars (if such Letter of Credit is denominated in a currency other
than Dollars, the Dollar equivalent of such currency) available to be drawn
under such Letter of Credit (assuming compliance with all conditions to
drawing).  Subject to the limits referred to above, Company may request the
issuance of Letters of Credit under this Section 2.16(a), repay any Advances
resulting from drawings thereunder pursuant to Section 2.16(c) and request the
issuance of additional Letters of Credit under this Section 2.16(a).  Issuing
Bank and Lenders acknowledge that all conditions precedent to the issuance of
the Existing Letters of Credit have been satisfied.

         (b)     Request for Issuance.  Each Letter of Credit shall be issued
upon notice, given not later than 11:00 a.m. on the Business Day prior to the
date of the proposed issuance of such Letter of Credit, by Company to Issuing
Bank, which shall give to Administrative Lender and each Lender prompt notice
thereof by telex, telecopier or cable.  Each Letter of Credit shall be issued
upon notice given in accordance with the terms of any separate application and
agreement between Company and Issuing Bank in form and substance reasonably
satisfactory to Company and Issuing Bank providing for the issuance of Letters
of Credit pursuant to this Agreement and containing terms and conditions not
inconsistent with this Agreement (a "Letter of Credit Agreement"), provided
that if any such terms and conditions are inconsistent with this Agreement,
this Agreement shall control.  Each such request for issuance of a Letter of
Credit (a "Request for Issuance") shall be by telex or telecopier, and shall be
in substantially the form of Exhibit E.  If the Letter of Credit requested is
to be denominated in a currency other than Dollars or Eurocurrencies, Issuing
Bank shall notify Company within twenty-four hours of receipt of the Request
for Issuance of the availability of such currency and the expiry date available
for Letters of Credit denominated in such currency.  If the requested terms of
such Letter of Credit are acceptable to Issuing Bank in its reasonable
discretion, Issuing Bank will, upon fulfillment of the applicable conditions
set forth in Article III, make such Letter of Credit available to Company at
Company's office referred to in Section 10.01 or as otherwise agreed with
Company in connection with such issuance on the proper issuance date.

         (c)     Drawing and Reimbursement.  Unless funds are otherwise made
available by Company to Issuing Bank, the payment by Issuing Bank of a draft
drawn under any Letter of Credit shall constitute for all purposes of this
Agreement the making by Issuing Bank of a Dollar Advance, which shall bear
interest at the Base Rate in the amount of such draft (but without any
requirement for compliance with the conditions set forth in Article III).
Issuing Bank shall notify Company within one Business Day of its receipt of a
draw request with respect to a Letter of Credit issued in other than Dollars.
Company, within one Business Day of receipt of such notice from Issuing Bank,
shall notify Issuing Bank whether Company intends to make funds available to
Administrative Lender in such currency.  Upon payment by Issuing Bank of a
draft drawn under a Letter of Credit, Issuing Bank shall immediately notify
Company of such drawing.  In the event that such Dollar Advance is not
reimbursed by Company by 11:00 a.m. on the first Business Day after such
drawing, Issuing Bank shall promptly notify Administrative





                                     - 35 -
<PAGE>   42
Lender and each Lender.  Each Lender shall, on the first Business Day following
such notification, make a Dollar Advance, which shall bear interest at the Base
Rate, and shall be used to repay the applicable portion of Issuing Bank's
Advance with respect to such Letter of Credit, in an amount equal to the amount
of its participation in such drawing for application to reimburse Issuing Bank
(but without any requirement for compliance with the applicable conditions set
forth in Article III) and shall make available to Administrative Lender for the
account of Issuing Bank, by deposit at Administrative Lender's office, in same
day funds, the amount of such Dollar Advance.  In the event that any Lender
fails to make available to Administrative Lender for the account of Issuing
Bank the amount of such Dollar Advance, Issuing Bank shall be entitled to
recover such amount on demand from such Lender together with interest thereon
at a rate per annum equal to the lesser of (i) the Highest Lawful Rate and (ii)
the Federal Funds Effective Rate.

         (d)     Increased Costs.  If any change in any Law or in the
interpretation thereof by any Tribunal charged with the administration thereof
shall either (i) impose, modify or deem applicable any reserve, special deposit
or similar requirement against letters of credit or guarantees issued by, or
assets held by, or deposits in or for the account of, Issuing Bank or any
Lender or (ii) impose on Issuing Bank or any Lender any other condition
regarding this Agreement, Issuing Bank, such Lender or any Letter of Credit,
and the result of any event referred to in the preceding clause (i) or (ii)
shall be to increase the cost to Issuing Bank of issuing or maintaining any
Letter of Credit or to any Lender of purchasing any participation therein or
making any Dollar Advance pursuant to Section 2.16(c), then, upon written
demand by Issuing Bank or such Lender, Company shall, subject to Section 10.09,
pay to Issuing Bank or such Lender, from time to time as specified by Issuing
Bank or such Lender in the below-mentioned certificate, additional amounts that
shall be sufficient to reasonably compensate Issuing Bank or such Lender for
such increased cost.  A certificate as to the amount of such increased cost,
submitted to Company by Issuing Bank or such Lender, shall include in
reasonable detail the basis for the demand for additional compensation and
shall be conclusive and binding for all purposes, absent demonstrable error.
The obligations of Company under this Section 2.16(d) shall survive termination
of this Agreement.  Issuing Bank or any Lender claiming any additional
compensation under this Section 2.16(d) shall use reasonable efforts
(consistent with legal and regulatory restrictions) to reduce or eliminate any
such additional compensation which may thereafter accrue and which efforts
would not, in the sole discretion of Issuing Bank or such Lender, be otherwise
disadvantageous.

         (e)     Indemnity.  In addition to amounts payable as elsewhere
provided in this Article II, Company shall protect, indemnify, pay and save
Issuing Bank and each Lender harmless from and against any and all claims,
demands, liabilities, damages, losses, costs, charges and expenses (including
reasonable attorneys' fees) which Issuing Bank or any Lender may incur or be
subject to as a consequence, direct or indirect, of (i) the issuance of any
Letter of Credit other than, as a result of its willful misconduct or gross
negligence, as determined by a court of competent jurisdiction, or (ii) the
failure of Issuing Bank to honor a drawing under a Letter of Credit as a result
of any act or omission, whether rightful or wrongful, of any





                                     - 36 -
<PAGE>   43
present or future de jure or de facto Tribunal (all such acts or omissions
herein called "Government Acts").

         (f)     Assumption of Risk.  As among Company, the other Loan Parties,
Issuing Bank and Lenders, Company and the other Loan Parties assume all risks
of the acts and omissions of, or misuse of the Letters of Credit by, the
respective beneficiaries of the Letters of Credit.  In furtherance and not in
limitation of the foregoing, subject to the provisions of the Request for
Issuance, neither Issuing Bank nor any Lender or any of their respective
officers or directors shall be liable or responsible:  (i) for the form,
validity, sufficiency, accuracy, genuineness or legal effect of any document
submitted by any party in connection with the application for and issuance of
the Letters of Credit, even if it should in fact prove to be in any or all
respects invalid, insufficient, inaccurate, fraudulent or forged; (ii) for the
validity or sufficiency of any instrument transferring or assigning or
purporting to transfer or assign a 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) for failure of the beneficiary of
a Letter of Credit to comply duly with conditions required in order to draw
upon such Letter of Credit; (iv) for errors, omissions, interruptions or delays
in transmission or delivery of any messages, by mail, cable, telegraph, telex
or otherwise, whether or not they be in cipher; (v) for errors in
interpretation of technical terms; (vi) for any loss or delay in the
transmission or otherwise of any document required in order to make a drawing
under any Letter of Credit or of the proceeds thereof; (vii) for the
misapplication by the beneficiary of a Letter of Credit of the proceeds of any
drawing under such Letter of Credit; and (viii) for any consequences arising
from causes beyond the control of Issuing Bank or any Lender, including,
without limitation, any Government Acts.  In furtherance and extension and not
in limitation of the specific provisions hereinabove set forth, any action
taken or omitted by Issuing Bank or any Lender under or in connection with the
Letters of Credit or any related certificates, shall not put Issuing Bank or
any Lender under any resulting liability to any Loan Party or relieve any Loan
Party of any of its obligations hereunder to any such Person unless such
liability to a Loan Party is proximately caused by the gross negligence of
Issuing Bank or any Lender, as determined by a court of competent jurisdiction,
and in such case, any resulting liability shall be solely that of the party so
adjudicated to have legal responsibility therefor.

         (g)     Compensation for Letters of Credit.

                 (i)      Letter of Credit Fees.  Subject to Section 10.09,
         Company shall pay, in respect of each Letter of Credit issued for its
         account, to Administrative Lender for the account of each Lender a
         letter of credit fee (which shall be payable quarterly in arrears on
         each Quarterly Date and on the Maturity Date) on the average daily
         amount available for drawing under all outstanding Letters of Credit
         (calculated in respect of Letters of Credit denominated in a currency
         other than Dollars, by using the quoted spot rate to exchange Dollars
         for such currency in effect on the last day of each Quarterly Date as
         the rate in effect during the calendar quarter ending on such
         Quarterly Date) (including the Existing Letters of Credit), computed,
         subject to Section 10.09, on the basis of a year of 365 or 366 days,
         as appropriate, for the actual number of days elapsed, at a rate per





                                     - 37 -
<PAGE>   44
         annum equal to the LIBOR Margin percentages set forth in the
         definition of Applicable Margin in Section 1.01.

                 (ii)     Adjustment of Letter of Credit Fee.  The letter of
         credit fee payable in respect of the Letters of Credit shall be
         subject to reduction or increase, as applicable and as set forth in
         the table contained in the definition of Applicable Margin in Section
         1.01 according to the performance of Company as tested by the
         Consolidated Funded Debt to Consolidated Excess Cash Flow Ratio.  Any
         such increase or reduction in such fee shall be effective as of the
         day following the date of receipt of the financial statements required
         pursuant to Section 5.01(a) or (b), as appropriate.  If such financial
         statements are not received by the day following the date required,
         the fee payable in respect of the Letters of Credit shall be
         determined as if the Consolidated Funded Debt to Consolidated Excess
         Cash Flow Ratio is greater than or equal to 2.00 to 1 until such time
         as such financial statements are received.  Notwithstanding anything
         herein to the contrary, the letter of credit fee payable in respect of
         the Letters of Credit from and including the Agreement Date to but not
         including the day following receipt of Company's March 31, 1996,
         financial statements shall be 0.55%.

                 (iii)    Issuance Fee.  Subject to Section 10.09, Company
         shall pay, in respect of each Letter of Credit issued for its account,
         to Administrative Lender for the sole account of Issuing Bank an
         issuance fee (which fee shall be payable quarterly in arrears on each
         Quarterly Date and on the Maturity Date) equal to 0.125% per annum on
         the average daily amount available for drawing under all outstanding
         Letters of Credit (including the Existing Letters of Credit)
         (calculated in respect of Letters of Credit denominated in a currency
         other than Dollars, by using the quoted spot rate to exchange Dollars
         for such currency in effect on the last day of each Quarterly Date as
         the rate in effect during the calendar quarter ending on such
         Quarterly Date), and computed, subject to Section 10.09, on the basis
         of a year of 365 or 366 days, as appropriate, for the actual number of
         days elapsed.

ARTICLE IV.  REPRESENTATIONS AND WARRANTIES OF LOAN PARTIES

         Each Loan Party represents and warrants as to itself that:

         4.01.   Organization, Qualification, Authorization, Etc.  (a) Each
Loan Party (i) is a corporation or limited partnership duly organized, validly
existing and in good standing under the Laws of the jurisdiction of its
organization, (ii) is qualified to do business and is in good standing in each
jurisdiction in which the failure to be so qualified or be in good standing
(when considered alone or together with the failure of any other one or more of
them to be so qualified or be in good standing) would reasonably be expected to
have a Material Adverse Effect and (iii) has all requisite power and authority
(corporate and, to the knowledge of each Loan Party, otherwise) to own, lease,
operate and maintain its assets and to carry on its business as now conducted.
The jurisdiction under which each Loan Party is incorporated is listed on
Schedule 4.01.

         (b)     The execution, delivery and performance by each Loan Party of
this Agreement, the Notes and the other Loan Documents to which it is a party
have been duly authorized by all





                                     - 41 -
<PAGE>   48
necessary corporate or other required action on the part of such Loan Party.
Each of this Agreement and the other Loan Documents to which any Loan Party is
a party constitutes, and the Notes (when executed and delivered as contemplated
hereby) will constitute, legal, valid and binding obligations of such Loan
Party, enforceable in accordance with their respective terms, except as
enforcement thereof may be limited by Debtor Relief Laws and general principles
of equity (whether applied in a proceeding at law or in equity).

         4.02.   Full Disclosure.  (a) Neither this Agreement, the Notes, the
other Loan Documents, the documents and statements referred to in Section 4.04,
nor any other document delivered by or on behalf of any Loan Party contains any
untrue statement of a material fact or omits to state a material fact necessary
in order to make the statements contained herein or therein not misleading.
Company has furnished certain financial and operational forecasts to Lenders,
and with respect to such forecasts, this representation is not intended to
warrant the ability of Company to achieve such forecasts.

         (b)     There is no fact peculiar to any Loan Party which has a
Material Adverse Effect which has not been set forth in the Loan Documents or
in the other documents, certificates and statements furnished to Lenders by or
on behalf of Loan Parties at the direction of such Loan Party prior to the date
hereof in connection with the transactions contemplated hereby.

         4.03.   Changes, Etc.  Neither the business nor the properties of any
Loan Party is presently affected by any fire, explosion, accident, labor
controversy, strike, lockout or other dispute, embargo, act of God or act of a
public enemy or other similar event, condition or casualty which would
reasonably be expected to have a Material Adverse Effect, or if any such
existing event, condition or casualty were to continue for more than thirty
additional days (unless in the reasonable opinion of such Loan Party such event
or condition is not likely to continue for such period) would reasonably be
expected to have a Material Adverse Effect.

         4.04.   Financial Statements, Etc. Company has furnished Lenders with
its annual audited consolidated financial statements as at December 31, 1995.
Such financial statements (including any related schedules and/or notes) are
true, correct and complete in all material respects (subject, as to interim
statements, to changes resulting from audits and year-end adjustments), and
have been prepared in accordance with GAAP followed throughout the periods
involved. The balance sheets fairly present the consolidated condition of
Company and its consolidated Subsidiaries as at the dates thereof, and the
statements of income and statements of cash flow fairly present the
consolidated results of the operations of Company and its consolidated
Subsidiaries for the periods indicated. Since December 31, 1995, no events have
occurred which, individually or in the aggregate, would reasonably be expected
to have a Material Adverse Effect, except as disclosed in this Schedule 4.04 or
as otherwise disclosed to Lenders in writing.

         4.05.   Tax Returns and Payments.  Each Loan Party has filed or has
caused to be filed all United States federal income tax returns and all other
tax returns ("Other Returns") which are required by Law to be filed by it (or
obtained extensions with respect thereto) and has paid





                                     - 42 -
<PAGE>   49
all Taxes levied upon it or any of its properties, assets, income or franchises
which are due and payable; provided, however, that, if Company is in compliance
with Section 5.11, Loan Parties shall not be required to pay any Taxes or to
file any other Returns if (a) such Other Returns and Taxes do not involve an
obligation to pay Taxes of $5,000,000 or more, or (b) regardless of the amount
involved, the Taxes are being contested in good faith by appropriate
proceedings diligently conducted for which such reserves or other appropriate
provisions, if any, as shall be required by GAAP, have been made. The
consolidated federal income tax returns of Company and its consolidated
Subsidiaries have been examined and reported upon by the Internal Revenue
Service for all fiscal years to and including the fiscal year ended December
31, 1985.

         4.06.   Defaults Respecting Debt.  No payment default under the
provisions of any instrument evidencing any Debt (other than with respect to
trade payables the payment of which is being contested in good faith by
appropriate proceedings diligently conducted for which such reserves or other
appropriate provisions, if any, as shall be required by GAAP, have been made)
or under any agreement relating thereto and no other default under any such
instrument or agreement which is a default covered under Section 6.01(e) has
occurred which would reasonably be expected to have a Material Adverse Effect.

         4.07.   Property.  Each Loan Party has good and defensible title to
its real property and good and defensible title to all of its other property
and assets which are materially necessary for the operation of its business,
including the property and assets reflected in the consolidated balance sheet
as at December 31, 1995 referred to in Section 4.04 (other than properties and
assets disposed of in the ordinary course of business or as otherwise permitted
pursuant to the terms of this Agreement), and shall not be subject to any Lien
prohibited by Section 5.11.  All leases of real property, and all other
material leases necessary for the conduct of the respective businesses of Loan
Parties are valid and subsisting and are in full force and effect.

         4.08.   Conflicting Agreements or Restrictions.  The execution and
delivery of this Agreement and the other Loan Documents and the consummation of
the transactions contemplated hereby or thereby will not (a) conflict with, or
result in a breach of any of the terms or provisions of, or constitute a
default under, any indenture, mortgage, deed of trust, loan agreement or other
agreement or instrument relating to Debt of such Loan Party to which any Loan
Party is a party, (b) result in the creation of any Lien upon any of the
properties or assets of any Loan Party pursuant to any agreement or instrument
relating to Debt of such Loan Party to which any Loan Party is a party or (c)
result in any violation of (i) the provisions of the charter documents of any
Loan Party or (ii) any Law, which, in the case of clause (c)(ii), would
reasonably be expected to have a Material Adverse Effect; and, to the knowledge
of Loan Parties, no consent, approval, authorization, order, registration or
qualification of or with any court or governmental agency or body is required
for the consummation by Loan Parties of the transactions contemplated by this
Agreement.

         4.09.   Litigation, Etc.  Except as listed on Schedule 4.09, or as
otherwise disclosed to Lenders in writing, there is no action, suit,
investigation or proceeding pending or, to the knowledge of Loan Parties,
threatened against any Loan Party, or any property or rights of any





                                     - 43 -
<PAGE>   50
Loan Party, by or before any court, arbitrator or administrative or
governmental body which, having regard to (a) the size of the claim and (b)
whether there is a reasonable possibility of an adverse determination, would
reasonably be expected to have a Material Adverse Effect.

         4.10.   ERISA.  Each Loan Party and each member of its ERISA Group is
in compliance in all material respects with the applicable provisions of ERISA,
the Code and other Law with respect to the Plan(s) and Benefit Arrangement(s),
(for purposes of this sentence, "compliance in all material respects" means
such failure(s) to comply with respect to one or more Plan(s), and/or Benefit
Arrangement(s), individually or in the aggregate, would not result in a
Material Adverse Effect.)  All payments required to be made to or in respect of
a Plan, whether or not previously terminated, Multiemployer Plan or Benefit
Arrangement by a Loan Party or a member of its ERISA Group have been paid to
the extent that nonpayment would have a Material Adverse Effect.  No Loan Party
or any member of its ERISA Group has any unpaid liability under Title IV of
ERISA (other than a liability to the PBGC for premiums under section 4007 of
ERISA), which would result in a Material Adverse Effect.  There is no "amount
of unfunded benefit liabilities," as defined in section 4001(a)(18) of ERISA,
under any Plan and should complete or partial withdrawals occur with respect to
all Multiemployer Plans, the aggregate amount of such withdrawal
liability(ies), if any, would not reasonably be expected to have a Material
Adverse Effect.  To the knowledge of Loan Parties after reasonable
investigation, no litigation, proceeding(s), investigation(s) or claim(s)
(other than a routine, undisputed claim for benefits) is or are pending or, to
the knowledge of Loan Parties, threatened concerning any Plan(s), Multiemployer
Plan(s) or Benefit Arrangement(s), which, individually or in the aggregate,
would result in a Material Adverse Effect.  Except as disclosed in writing to
Administrative Lender prior to the Agreement Date, Loan Parties or a member of
their ERISA Group may terminate any and/or all currently existing Plan(s)
and/or Benefit Arrangement(s) so long as such termination would not reasonably
be expected to have a Material Adverse Effect.  As of the Agreement Date, Loan
Parties and/or members of the ERISA Group do not currently maintain, sponsor or
contribute to any employee pension benefit plan, as defined in Section 3(2) of
ERISA, which is subject to Title IV of ERISA or Section 412 of the Code.

         4.11.   Use of Proceeds.  Company will apply the proceeds of the
Advances for working capital and other general corporate purposes, including
loans to Subsidiaries of Company.  The proceeds of the Advances and the Letters
of Credit will be used to benefit all Loan Parties, directly or indirectly.

         4.12.   Federal Reserve Regulations.  No Loan Party is engaged,
principally or as one of its important activities, in the business of extending
credit for the purpose of purchasing or carrying "margin stock" (within the
meaning of Regulation G, T, U or X). The making of the Advances, the issuance
of the Letters of Credit and the execution, delivery, and performance of this
Agreement, the Notes and the other Loan Documents, and the use of the proceeds
of the Advances and the Letters of Credit do not and will not constitute a
violation of Regulation G, T, U or X.





                                     - 44 -
<PAGE>   51
         4.13.   Foreign Assets Control Regulations, Etc.  Neither the issue of
the Notes by Company nor the use of the proceeds thereof or of any Letter of
Credit contemplated by this Agreement will violate the Export Administration
Act, the Foreign Corrupt Practices Act of 1977, the Foreign Assets Control
Regulations, or any other regulations of the Office of Foreign Asset Control,
United States Treasury Department (31 C.F.R., Subtitle B, Chapter V, as
amended).

         4.14.   Status Under Certain Federal Statutes.  No Loan Party is (a)
an "investment company" or a company "controlled" by an "investment company,"
within the meaning of the Investment Company Act of 1940, as amended, (b) a
"holding company" or a "subsidiary company" of a "holding company," or an

                 Party, or of any Release or threatened Release of Hazardous
                 Materials, except for violations, noncompliances, obligations,
                 Releases or threatened Releases which, individually or in the

                 not reasonably be expected to have a Material Adverse Effect,
                 there are no writs, injunctions, decrees, orders or judgments
                 outstanding, or lawsuits, claims, proceedings or
                 investigations pending or, to the knowledge of any Loan Party,
                 threatened, relating to the current or former ownership, use,
                 maintenance, operation of, or conduct of business related to,

                 Adverse Effect; and

                          (J)     there are no material obligations,

         4.16.   Solvency.  Loan Parties, viewing their businesses and
operations as a single consolidated entity, have capital sufficient to carry on
their businesses and transactions and all businesses and transactions in which
they are about to engage, and are now solvent and able to pay their collective
debts as they mature, and Loan Parties now collectively own property having a
value, both at fair valuation and at present fair saleable value, greater than
the amount required to pay all existing debts of Loan Parties.

         4.17.   Senior Debt.  The Debt evidenced by the Notes and this
Agreement is senior to the Debt evidenced by the Subordinated Debt.  All terms
and provisions of the Subordinated Debt have been disclosed to Lenders, the
instruments evidencing the Subordinated Debt have not been amended or modified
except as disclosed in writing to Lenders, and no payments have been made in
respect of the Subordinated Debt other than regularly scheduled interest
payments.

         4.18.   Patents, Trademarks, Etc.  Loan Parties collectively possess
adequate assets, licenses, patents, patent applications, copyrights,
trademarks, service marks, trademark applications, trade names, technology,
processes, logotypes and Permits and other governmental approvals and
authorizations to conduct their businesses. Except as previously disclosed to
Lenders in writing, there are no existing or, to Loan Parties' knowledge,
threatened claims of any Person based on the use of such Permits, patents,
trademarks, trade names, copyrights, technology and processes by Loan Parties.
The consummation of the transactions contemplated by the Loan Documents will
not impair the ownership by Loan Parties of or the rights of any of such
parties under (or the license or other right to use, as the case may be) any
Permits, patents, trademarks, trade names, copyrights, technology or processes.

         4.19.   Labor Matters.  Except as disclosed in writing to Lenders, as
provided in Section 5.20, Schedule 4.19 sets forth a complete and correct list
of all labor union contracts to which any of Loan Parties is a party,
specifying the expiration date of each such contract and the nature of any
strikes, walkouts or other disputes related thereto.

Financial Officer.

         5.02.   Inspection of Property; Books and Records.  (a) Each Loan

it will pay or discharge all Taxes imposed upon it or any of its properties or
assets or in respect of any of its franchises, business, income or profits
before any penalty accrues thereon, and all claims (including, without
limitation, claims for labor, services, materials and supplies) for sums which
have become due and payable and which by Law have or may become a Lien upon any
of its property or assets, provided that no such Tax or claim need be paid or
discharged (a) while the same is being contested in good faith by appropriate
proceedings promptly instituted and diligently conducted and if such accrual or
other appropriate provision, if any, as shall be required by GAAP shall have
been made therefor or (b) if the aggregate amount of all such unpaid Taxes and
claims for all Loan Parties does not exceed $5,000,000 (without regard to

faith by appropriate proceedings diligently conducted for which such reserves
or other appropriate provisions, if any, as shall be required by GAAP, have

Lender (i) at least annually, a summary of all insurance coverage of Loan
Parties prepared by an independent insurance broker and (ii) upon request of

         5.06.   Compliance with Laws.

         (a)     Company shall comply with all Laws, the non-compliance with
which, when considered alone or together with all non-compliance with such Laws
by all such Loan Parties,





                                     - 52 -
<PAGE>   59
would reasonably be expected to have a Material Adverse Effect; provided,
however, such Loan Party shall have the right to diligently contest any Law so
long as (i) the contest is in good faith and by appropriate proceedings and
such reserve or other appropriate provision, if any, as shall be required by
GAAP shall have been made therefor and (ii) such contest shall operate to
suspend the collection of any disputed amount from any property of such Loan
Party and any forfeiture or sale of such property.

         (b)     Notwithstanding, and without limitation of the foregoing, each
Loan Party shall (i) comply in a timely fashion with, or operate pursuant to
valid waivers of the provisions of, all Environmental Laws, including, without
limitation, any such Laws relating to contamination from, or remedial
obligations in connection with, any Hazardous Materials, (ii) obtain, where its
business is to be changed so it is different than the business presently
conducted, all environmental Permits necessary for the conduct of its business
as intended to be so conducted, with such Permits obtained prior to such
change, (iii) notify each Lender promptly in the event of any actual or alleged
noncompliance with any Environmental Laws and (iv) promptly forward to each
Lender a copy of any claim, judgment, order, notice, applications for Permits,
Permits or other communication or report in connection with any material matter
relating to Environmental Law as it may affect any Loan Party or any of their
respective assets.

         5.07.   Performance of Loan Documents.  Each Loan Party will duly and
punctually pay and perform their respective obligations under the Loan
Documents to which it is a party in accordance with, and without breach of, the
terms of each thereof.

         5.08.   Indemnification.

         (a)     Loan Parties shall, jointly and severally indemnify and hold
harmless each Indemnitee from and against any and all claims, damages and
liabilities whatsoever which any Indemnitee may directly or indirectly incur
(or which may be claimed against such Indemnitee by any Person or entity
whatsoever) by reason of or in connection with (i) this Agreement, Advances or
the Letters of Credit (including without limitation the enforcement of this
Agreement, the Notes and the other Loan Documents and the defense of such
Indemnitee's actions and inactions in connection therewith); (ii) any breach of
any Loan Party or any other Person of any warranty, covenant, term or condition
in, or the occurrence of any default under, this Agreement, the Notes or any
other Loan Document, including all reasonable fees or expenses resulting from
the settlement or defense of any claims or liabilities arising as a result of
any such breach or default; and (iii) involvement in any legal suit,
investigation, proceeding, inquiry or action as to which any Indemnitee is
involved as a consequence, directly or indirectly, of the making of any
Advance, the issuance of any Letter of Credit, its execution of this Agreement
or the other Loan Documents or any other event or transaction contemplated by
any of the foregoing.  Nothing in this Section 5.08 is intended to limit the
obligations of Loan Parties contained in any other Section of this Agreement.
Loan Parties jointly and severally shall pay all expenses (including without
limitation fees and disbursements of counsel) reasonably incurred by each
Indemnitee in investigating, defending or preparing to defend against any such
claim, damage or liability and for all costs of settlement made with the
written consent of





                                     - 53 -
<PAGE>   60
Company in connection with any such claim, damage or liability.  However, such
indemnities shall not apply to any particular Indemnitee (but shall apply to
the other Indemnitees) to the extent the subject of the indemnification is
caused by or arises out of the gross negligence or willful misconduct of such
particular Indemnitee. Notwithstanding any provision to the contrary contained
herein, no Indemnitee will be indemnified for liability arising in connection
with its gross negligence or willful misconduct.

         (b)     Without limiting any provision of this Agreement, it is the
express intention of the parties hereto that each Indemnitee shall be
indemnified and held harmless against any and all losses, liabilities, claims
or damages arising out of or resulting from the ordinary, sole or contributory
negligence of such Indemnitee. Without prejudice to the survival of any other
obligations of Loan Parties under this Agreement, the Notes or the other Loan
Documents, the obligations of Loan Parties under this Section 5.08 shall
survive the termination of this Agreement.

         5.09.   Legal Existence, Etc.  Except as expressly permitted by
Section 5.12(b), each Loan Party covenants that it will, at all times, preserve
and maintain its legal existence, rights, privileges and franchises material to
its business and will qualify to do business in any jurisdiction where the
failure to do so when considered alone or together with the failure of any or
all of the other Loan Parties to do so would reasonably be expected to have a
Material Adverse Effect.

         5.10.   Ownership of Loan Parties.  Company will at all times own and
hold the entire legal title to and beneficial interest, either directly or
indirectly through one or more intermediaries, in all outstanding shares of all
classes of the capital stock or other equity interests of the other Loan
Parties.

         5.11.   Liens.  Loan Parties will not create or otherwise allow any
Liens to exist on or otherwise to affect any of its assets, except the
following Liens which shall be permitted:

         mechanics' liens, and liens to secure claims for labor, material or
         supplies arising in the ordinary course of business, but only to the
         extent that payment thereof shall not at the time be due or is being
         contested in good faith by appropriate proceedings diligently
         conducted and with respect to which appropriate reserves have been set
         aside in accordance with GAAP, and so long as the enforcement thereof
         has been stayed and such Liens do not individually or in the aggregate
         materially impair the value or materially interfere with the use of
         the property subject thereto or the operation of the usual business of
         the Loan Parties involved;

                 (b)      Deposits or pledges to enable Loan Parties to

         to secure the performance of bids, tenders, contracts (other than
         those relating to borrowed

         diligently conducted and there have been set aside on its books
         appropriate reserves with respect thereto and in accordance with GAAP,
         and so long as the enforcement thereof has been stayed and such Liens
         do not individually or in the aggregate materially impair the value or
         materially interfere with the use of the property subject thereto or
         the operation of the usual business of the Loan Parties involved;

         a Loan Party for the purpose of obtaining a stay or discharge of any
         legal proceeding to which such Person is a party, provided, however,

         6.01(i);

         Taxes, assessments, levies or charges must either (i) not yet be due
         or (ii) be the subject of a pending contest made in good faith by
         appropriate proceedings diligently conducted and with respect to which
         appropriate reserves have been set aside in accordance with GAAP (so
         long as the enforcement of the Liens with respect to the contested
         amounts has been stayed and such Liens do not individually or in the

                 (h)      Liens which are described on Schedule 5.11 and

                 (iii)    any Loan Party (other than Company) may merge into or
         consolidate with any Loan Party (other than Company), provided that
         Company and its consolidated Subsidiaries are no less creditworthy in
         the reasonable opinion of Lenders immediately after such merger or
         consolidation; or

                 (iv)     any Loan Party may accomplish a consolidation or
         merger via a stock for stock transaction, provided, that in each case
         (A) a Loan Party (provided, in the event Company is involved in any
         such consolidation or merger, Company must be the survivor) is the
         survivor and (B) the consolidation or merger would not have a Material
         Adverse Effect.

         (c)     Company may, at Company's option, after any Person becomes a
direct or indirect Domestic Subsidiary of Company (each such Subsidiary being a

form and substance satisfactory to Lenders, and (B) a copy of the resolutions
of the board of directors or similar governing body of such Subsidiary
approving the form of the Assumption Agreement and such amendment, their

employees of such Person) with any officer, director or holder of any of the
outstanding capital stock of such Person or any Affiliate, unless such
Investment, transaction, contract or agreement is made (i) upon terms and
conditions no less favorable to any Loan Party that is a party thereto than
terms and conditions which could have been obtained from wholly independent and
unrelated sources, and (ii) in the ordinary course of business of the Loan
Party and Affiliate in question; provided, however, nothing in this Section
5.13 shall prohibit sales or transfers of inventory, equipment or any other
asset from any

with actual intent to delay, defraud or hinder collection or enforcement of any
rights of Administrative Lender or any Lender under this Agreement, or
otherwise at Law or in equity; and provided, further, that no Loan Party shall
directly or indirectly transfer or otherwise dispose of any of its assets in a
transaction with an Affiliate of such Loan Party wherein the Loan Party
receives less than reasonably equivalent value (as such term is used and
construed in Section 548 of the United States Bankruptcy Code) in exchange for
such transfer, regardless of the solvency of such Loan Party.

         6.02.   Remedies.  If an Event of Default shall have occurred and
shall be continuing:

         (a)     With the exception of an Event of Default specified in Section
6.01(a), Section 6.01(g) or Section 6.01(h), Administrative Lender shall, upon
the direction of the Required Lenders, by notice to Company terminate the
Commitment and/or declare the principal of and interest on the Advances and all
other Obligations (including the aggregate amount of the Reimbursement
Obligations outstanding at such time) to be forthwith due and payable without
presentation, demand, protest, notice of intent to accelerate, notice of
acceleration or other notice of any kind (other than notice as expressly
provided herein), all of which are hereby expressly waived, anything in this
Agreement or the other Loan Documents to the contrary notwithstanding.

         (b)     Upon the occurrence of an Event of Default specified in
Section 6.01(a), Administrative Lender shall, upon direction of the Determining
Lenders, by notice to Company terminate the Commitment and/or declare the
principal of and interest on the Advances and all other Obligations (including
the aggregate amount of the Reimbursement Obligations outstanding at such time)
to be forthwith due and payable without presentation, demand, protest, notice
of intent to accelerate, notice of acceleration or other notice of any kind
(other than notice as expressly provided herein), all of which are hereby
expressly waived, anything in this Agreement or the other Loan Documents to the
contrary notwithstanding.

         (c)     Upon the occurrence of an Event of Default specified in
Section 6.01(g) or Section 6.01(h), the principal of and interest on the
Advances and all other Obligations (including the aggregate amount of the
Reimbursement Obligations outstanding at such time) shall thereupon and
concurrently therewith become due and payable and the Commitment shall
forthwith terminate, all without any action by Administrative Lender, any
Lender or any holders of the Notes and without presentment, demand, protest,
notice of intent to accelerate, notice of acceleration or other notice of any
kind, all of which are expressly waived, anything in this Agreement or the
other Loan Documents to the contrary notwithstanding.

         (d)     Loan Parties recognize that notwithstanding any termination of
the Commitment pursuant to Section 6.02(a), Section 6.02(b) or Section 6.02(c),
the obligation of Issuing Bank





                                     - 63 -
<PAGE>   70
to fund draws against Letters of Credit outstanding on the Maturity Date, as
accelerated pursuant to the said Section 6.02, shall continue until expiration
of each such Letter of Credit.  In consideration of the agreement of Lenders to
not require that Loan Parties provide cash collateral to secure the
Reimbursement Obligations in respect of the Letters of Credit outstanding on
the Maturity Date, as so accelerated, Loan Parties hereby unconditionally and
irrevocably agree that upon any acceleration of the Obligations pursuant to
Section 6.02(a), Section 6.02(b) or Section 6.02(c), the aggregate amount of
the Reimbursement Obligations outstanding at such time shall be immediately due
and payable in full.

                 To the extent that amounts received by Administrative Lender
and Lenders in the exercise of their post- default rights granted to them under
the Loan Documents and under Applicable Law exceed the unpaid Obligations
(other than the outstanding Reimbursement Obligations), such excess, up to an
amount equal to the aggregate amount of the Reimbursement Obligations, shall be
deposited in a deposit account maintained by Administrative Lender (the
"Reimbursement Obligation Account").  Title to, and ownership of, the
Reimbursement Obligation Account shall be in and for the benefit of Lenders and
the Reimbursement Obligation Account shall be under the sole dominion and
control of Administrative Lender.  Except as set forth herein, no Loan Party
shall have any interest or right with respect to the Reimbursement Obligation
Account.  Administrative Lender, as draws are made against Letters of Credit,
shall apply the funds in the Reimbursement Obligation Account to the unpaid
Obligations then outstanding.  After all Letters of Credit have been funded or
expired by their terms, and all unpaid Obligations then outstanding have been
paid in full, Administrative Lender shall refund any amount remaining in the
Reimbursement Obligation Account to Company.  Loan Parties acknowledge that (i)
if the Letters of Credit outstanding on the Maturity Date are not extended
beyond their respective expiration dates in effect on the Maturity Date, such
Letters of Credit will be drawn upon on or prior to their respective expiration
dates, (ii) Issuing Bank will not extend the expiration date of any Letter of
Credit outstanding on the Maturity Date, (iii) as a result of clauses (i) and
(ii) immediately preceding, the Reimbursement Obligations of Company will be a
fixed amount in the aggregate amount of the Letters of Credit outstanding on
the Maturity Date and not a contingent amount and (iv) as a result of clauses
(i), (ii) and (iii) immediately preceding, no provision herein shall be deemed
to be a confession of judgment.

         (e)     Subject to the terms and provisions of the Loan Documents,
Administrative Lender and Lenders may exercise all of the post-default rights
granted to them under the Loan Documents or under Applicable Law.

         (f)     The rights and remedies of Administrative Lender and Lenders
hereunder shall be cumulative, and not exclusive.

         6.03.   Injunctive Relief.  Loan Parties recognize that in the event
they fail to perform, observe or discharge any of their obligations or
liabilities under this Agreement or any other Loan Document, any remedy of law
may prove to be inadequate relief to Lenders; therefore, Loan Parties agree
that Lenders, if Lenders so requests, shall be entitled to temporary and
permanent injunctive relief in any such case without the necessity of proving
actual damages.

ARTICLE VII.  GUARANTY

         7.01.   Guaranty.  In consideration of the Commitment, Guarantors
hereby absolutely, unconditionally and irrevocably, jointly and severally
guarantee the punctual payment and performance when due, whether at stated
maturity, by acceleration or otherwise, of the Obligations (including, without
limitation, interest accruing or becoming owing both prior to and subsequent to
the commencement of any proceeding against or with respect to Company under any
Debtor Relief Law), fees, commissions, expenses (including reasonable
attorneys' fees and expenses) or otherwise, and all reasonable costs and
expenses, if any, incurred by Administrative Lender, Issuing Bank and Lenders
in connection with enforcing any rights under this Guaranty (all such
obligations being the "Guaranteed Obligations"), and agree to pay any and all
reasonable expenses incurred by Administrative Lender, Issuing Bank and Lenders
in enforcing this Guaranty. This Guaranty is an absolute, unconditional,
present and continuing guaranty of payment and not of collectibility and is in
no way conditioned upon any attempt to collect from Company or any other
action, occurrence or circumstance whatsoever.

         7.02.   Continuing Guaranty.  Each Guarantor guarantees that the
Guaranteed Obligations will be paid strictly in accordance with the terms of
this Agreement, the Notes and the other Loan Documents.  Each Guarantor agrees
that the Guaranteed Obligations and Loan Documents may be extended or renewed,
and Advances repaid and reborrowed in whole or in part, without notice to or
assent by such Guarantor, and that it will remain bound upon this Guaranty
notwithstanding any extension, renewal, restatement, or other alteration of any
Guaranteed Obligations or Loan Documents, or any repayment and reborrowing of
Advances.  The obligations of each Guarantor under this Guaranty shall be
absolute, unconditional and irrevocable, and shall be performed strictly in
accordance with the terms hereof under any circumstances whatsoever, including:

         (a)     any increase, restatement, extension, renewal, modification,
settlement, compromise, waiver or release in respect of any Guaranteed
Obligations;

         (b)     any restatement, extension, renewal, amendment, modification,
rescission, waiver or release in respect of any Loan Documents;

         (c)     any release, exchange, substitution, non-perfection or
invalidity of, or failure to exercise rights or remedies with respect to, any
direct or indirect security for any Guaranteed Obligations, including the
release of any other Guarantor or other Loan Party;





                                     - 65 -
<PAGE>   72
         (d)     any change in the corporate existence, structure or ownership
of any Loan Party, or any insolvency, bankruptcy, reorganization, or other
similar proceeding affecting any Loan Party or any of their respective assets;
or

         (e)     the existence of any claim, defense, set-off or other rights
or remedies which such Guarantor at any time may have against any other Loan
Party, whether in connection with this Guaranty, the Loan Documents, the
transactions contemplated thereby or any other transaction.

         7.03.   Effect of Debtor Relief Laws.  If after receipt of any payment
of, or proceeds of any security applied (or intended to be applied) to the
payment of all or any part of the Guaranteed Obligations, Administrative
Lender, Issuing Bank, or any Lender is for any reason compelled to surrender or
voluntarily surrenders, such payment or proceeds to any Person (a) because such
payment or application of proceeds is or may be avoided, invalidated, declared
fraudulent, set aside, determined to be void or voidable as a preference,
fraudulent conveyance, fraudulent transfer, impermissible set-off or a
diversion of trust funds, or (b) for any other reason, including (i) any
judgment, decree or order of any court or administrative body having
jurisdiction over Administrative Lender, Issuing Bank, or any Lender or any of
its properties, or (ii) any settlement or compromise of any such claim effected
by Administrative Lender, Issuing Bank, or any Lender with any such claimant
(including Company), then the Guaranteed Obligations or part thereof intended
to be satisfied shall be reinstated and continue, and this Guaranty shall
continue in full force as if such payment or proceeds have not been received,
notwithstanding any revocation thereof or the cancellation of the Notes or any
other instrument evidencing any Guaranteed Obligations or otherwise; and
Guarantors, jointly and severally, shall be liable to pay Administrative
Lender, Issuing Bank, or such Lender, and hereby do indemnify Administrative
Lender, Issuing Bank, and such Lender and hold it harmless for the amount of
such payment or proceeds so surrendered and all expenses (including reasonable
attorneys' fees, court costs and expenses attributable thereto) incurred by
Administrative Lender, Issuing Bank, and such Lender in the defense of any
claim made against it that any payment or proceeds received by Administrative
Lender, Issuing Bank, and such Lender in respect of all or part of the
Guaranteed Obligations must be surrendered. The provisions of this Section 7.03
shall survive the termination of this Guaranty, and any satisfaction and
discharge of Company by virtue of any payment, court order or any Law.

         7.04.   Waiver of Subrogation.  Notwithstanding any payment or
payments made by any Guarantor hereunder, or any set-off or application by
Administrative Lender, Issuing Bank, or any Lender of any security or of any
credits or claims, no Guarantor will assert or exercise any rights of
Administrative Lender, Issuing Bank, or any Lender or of such Guarantor against
Company to recover the amount of any payment made by such Guarantor to
Administrative Lender, Issuing Bank, or any Lender hereunder by way of
subrogation, reimbursement, contribution, indemnity, or otherwise arising by
contract or operation of Law, and such Guarantor shall not have any right of
recourse to or any claim against assets or property of Company, whether or not
the obligations of Company have been satisfied, all of such rights being herein
expressly waived by such Guarantor.  Each Guarantor agrees not to seek
contribution or indemnity or other recourse from any other Loan Party or other
Person.  If any





                                     - 66 -
<PAGE>   73
amount shall nevertheless be paid to a Guarantor by any other Loan Party or
another Guarantor prior to payment in full of the Guaranteed Obligations, such
amount shall be held in trust for the benefit of Administrative Lender, Issuing
Bank, and Lenders and shall forthwith be paid to Administrative Lender to be
credited and applied to the Guaranteed Obligations, whether matured or
unmatured.  The provisions of this Section 7.04 shall survive the termination
of this Guaranty, and any satisfaction and discharge of Company by virtue of
any payment, court order or any Law.

         7.05.   Subordination.  If any Guarantor becomes the holder of any
indebtedness payable by Company, each Guarantor hereby subordinates all
indebtedness owing to it from Company to all indebtedness of Company to
Administrative Lender, Issuing Bank, and Lenders, and agrees that upon the
occurrence and continuance of a Default or an Event of Default, it shall not
accept any payment on the same until payment in full of the obligations of
Company under this Agreement, the Notes and all other Loan Documents, and shall
in no circumstance whatsoever attempt to set-off or reduce any obligations
hereunder because of such indebtedness. If any amount shall nevertheless be
paid to a Guarantor by Company prior to payment in full of the Guaranteed
Obligations, such amount shall be held in trust for the benefit of
Administrative Lender, Issuing Bank, and Lenders and shall forthwith be paid to
Administrative Lender to be credited and applied to the Guaranteed Obligations,
whether matured or unmatured.

         7.06.   Waiver.  Each Guarantor hereby waives promptness, diligence,
notice of acceptance and any other notice with respect to any of the Guaranteed
Obligations and this Guaranty and waives presentment, demand of payment, notice
of intent to accelerate, notice of acceleration, notice of dishonor or
nonpayment and any requirement that Administrative Lender, Issuing Bank, or any
Lender institute suit, collection proceedings or take any other action to
collect the Guaranteed Obligations, including any requirement that
Administrative Lender, Issuing Bank, or any Lender protect, secure, perfect or
insure any Lien against any property subject thereto or exhaust any right or
take any action against any Loan Party or any other Person or any collateral
(it being the intention of Administrative Lender, Issuing Bank, and each Lender
and each Guarantor that this Guaranty is to be a guaranty of payment and not of
collection).  It shall not be necessary for Administrative Lender, Issuing
Bank, or any Lender, in order to enforce any payment by any Guarantor
hereunder, to institute suit or exhaust its rights and remedies against any
Loan Party or any other Person, including others liable to pay any Guaranteed
Obligations, or to enforce its rights against any security ever given to secure
payment thereof. Each Guarantor hereby expressly waives each and every right to
which it may be entitled by virtue of the suretyship laws of the State of
Texas, including, without limitation, any and all rights it may have pursuant
to Rule 31, Texas Rules of Civil Procedure, Section 17.001 of the Texas Civil
Practice and Remedies Code and Chapter 34 of the Texas Business and Commerce
Code.  Each Guarantor hereby waives marshaling of assets and liabilities,
notice by Administrative Lender, Issuing Bank, or any Lender of any
indebtedness or liability to which Administrative Lender, Issuing Bank, or any
Lender applies or may apply any amounts received by Administrative Lender,
Issuing Bank, or any Lender, and of the creation, advancement, increase,
existence, extension, renewal, rearrangement and/or modification of the
Guaranteed Obligations. Each Guarantor expressly waives, to the extent
permitted by Applicable Law, the





                                     - 67 -
<PAGE>   74
benefit of any and all Laws providing for exemption of property from execution
or for valuation and appraisal upon foreclosure.

         7.07.   Full Force and Effect.  This Guaranty is a continuing guaranty
of payment and shall remain in full force and effect until final payment in
full after the Maturity Date of the Obligations of all Loan Parties under this
Agreement, the Note and all other Loan Documents and all other amounts payable
under this Guaranty.

         7.08.   Enforceability.  Notwithstanding any other provision of this
Article VII, if any one or more provisions of this Guaranty should be invalid,
illegal or unenforceable in any respect, the validity, legality and
enforceability of the remaining provisions contained herein shall not in any
way be affected, impaired, prejudiced or disturbed thereby. If at any time any
portion of the obligations of Guarantors under this Guaranty shall be
determined by any Tribunal to be invalid, unenforceable or avoidable, the
remaining portion of the obligations of Guarantors under this Guaranty shall
not in any way be affected, impaired, prejudiced or disturbed thereby and shall
remain valid and enforceable to the fullest extent permitted by Applicable Law.
If at any time all or any portion of the obligation of Guarantors under this
Guaranty would otherwise be determined by a court of competent jurisdiction to
be invalid, unenforceable or avoidable under Section 548 of the United States
Bankruptcy Code or under a similar Debtor Relief Law of any jurisdiction, then
notwithstanding any other provisions of this Guaranty to the contrary such
obligation or portion thereof of Guarantors under this Guaranty shall be
limited to the greatest of (a) the value of any quantifiable economic benefits
accruing to Guarantors as a result of this Guaranty, (b) an amount equal to 95%
of the excess on the date the relevant liabilities were incurred of the present
fair saleable value of the assets of Guarantors over the amount of all
liabilities of Guarantors, contingent or otherwise, and (c) the maximum amount
for which this Guaranty is determined to be enforceable under Applicable Law.


ARTICLE VIII.  CHANGES IN CIRCUMSTANCES

         8.01.   LIBOR Basis or Eurocurrency Basis Determination Inadequate.
If with respect to any proposed LIBOR Advance or Eurocurrency Advance for any
Interest Period, any Lender determines in good faith that (a) deposits in
Dollars or a Eurocurrency (in the applicable amount) are not being offered to
that Lender in the relevant market for such Interest Period or (b) the LIBOR
Basis or Eurocurrency Basis for such proposed LIBOR Advance or Eurocurrency
Advance, respectively, does not adequately cover the cost to such Lender of
making and maintaining such proposed LIBOR Advance or Eurocurrency Advance for
such Interest Period, such Lender shall forthwith give notice thereof to
Company, whereupon until such Lender notifies Company that the circumstances
giving rise to such situation no longer exist, the obligation of such Lender to
make LIBOR Advances or Eurocurrency Advance, as appropriate, shall be
suspended.

         8.02.   Illegality.  If any Applicable Law, or any change therein or
adoption thereof, or interpretation or administration thereof by any Tribunal,
central bank or comparable agency





                                     - 68 -
<PAGE>   75
charged with the interpretation or administration thereof, or compliance by any
Lender (or its LIBOR Lending Office or Eurocurrency Lending Office) with any
request or directive (whether or not having the force of law) of any such
Tribunal, central bank or comparable agency, shall make it unlawful or
impossible for such Lender (or its LIBOR Lending Office or Eurocurrency Lending
Office) to make, maintain or fund its LIBOR Advances or Eurocurrency Advances,
such Lender shall so notify Company, Administrative Lender.  Before giving any
notice to Company pursuant to this Section 8.02, the notifying Lender shall
designate a different LIBOR Lending Office, Eurocurrency Lending Office or
other lending office if such designation will avoid the need for giving such
notice and will not, in the sole judgment of such Lender, be materially
disadvantageous to such Lender.  Upon receipt of such notice, notwithstanding
anything contained in Article II, Company shall repay in full the then
outstanding principal amount of each LIBOR Advance or Eurocurrency Advance
owing to the notifying Lender, together with accrued interest thereon, on
either (a) the last day of the Interest Period applicable to such Advance, if
such Lender may lawfully continue to maintain and fund such Advance to such
day, or (b) immediately, if such Lender may not lawfully continue to fund and
maintain such Advance to such day.  Concurrently with repaying each affected
LIBOR Advance or Eurocurrency Advance owing to such Lender along with any
reimbursement required under Section 2.09, notwithstanding anything contained
in Article II, Company shall borrow a Base Rate Advance from such Lender, and
such Lender shall make such Base Rate Advance, in an amount such that the
outstanding principal amount of the Advances owing to such Lender shall equal
the outstanding principal amount of the Advances owing immediately prior to
such repayment.

         8.03.   Increased Costs.

         (a)     If any Applicable Law, or any change in or adoption of any
Law, or any interpretation or administration thereof by any Tribunal, central
bank or comparable agency charged with the interpretation or administration
thereof or compliance by any Lender (or its LIBOR Lending Office or
Eurocurrency Lending Office) with any request or directive (whether or not
having the force of law) or any such Tribunal, central bank or compatible
agency:

                 (i)      shall subject a Lender (or its LIBOR Lending Office
         or Eurocurrency Lending Office) to any Tax (net of any tax benefit
         engendered thereby) with respect to its LIBOR Advances or its
         Eurocurrency Advances or its obligation to make LIBOR Advances or
         Eurocurrency Advances, or shall change the basis of taxation of
         payments to a Lender (or to its LIBOR Lending Office or Eurocurrency
         Lending Office) of the principal of or interest on its LIBOR Advances
         or Eurocurrency Advances or in respect of any other amounts due under
         this Agreement, as the case may be, or its obligation to make LIBOR
         Advances or Eurocurrency Advances (except for changes in the rate of
         tax on the overall net income, net worth or capital of such Lender and
         franchise taxes, doing business taxes or minimum taxes imposed upon
         such Lender); or

                 (ii)     shall impose, modify or deem applicable any reserve
         (including, without limitation, any imposed by the Board of Governors
         of the Federal Reserve System);





                                     - 69 -
<PAGE>   76
         special deposit or similar requirement against assets of, deposits
         with or for the account of, or credit extended by, a Lender's LIBOR
         Lending Office or Eurocurrency Lending Office or shall impose on such
         Lender (or its LIBOR Lending Office or Eurocurrency Lending Office) or
         on the United States market for certificates of deposit, the London
         interbank market or the Eurocurrency Interbank Market any other
         condition affecting its LIBOR Advances or its Eurocurrency Advances or
         its obligation to make such Advances;

and the result of any of the foregoing is to increase the cost to a Lender (or
its LIBOR Lending Office or its Eurocurrency Lending Office) of making or
maintaining any LIBOR Advances or Eurocurrency Advances, or to reduce the
amount of any sum received or receivable by a Lender (or its LIBOR Lending
Office or its Eurocurrency Lending Office) with respect thereto, by an amount
reasonably deemed by a Lender to be material, then, within fifteen days after
demand by a Lender, Company shall pay to such Lender such additional amount as
will reasonably compensate such Lender for such increased costs or reduced
amounts, subject to Section 10.09.  The affected Lender will as soon as
practicable notify Company of any event of which it has knowledge, occurring
after the date hereof, which will entitle such Lender to compensation pursuant
to this Section 8.03 and will designate a different LIBOR Lending Office or
Eurocurrency Lending Office or other lending office if such designation will
avoid the need for, or reduce the amount of, such compensation and will not, in
the sole judgment of the affected Lender made in good faith, be disadvantageous
to such Lender.

         (b)     A certificate of any Lender claiming compensation under this
Section 8.03 and setting forth the additional amounts to be paid to it
hereunder and calculations therefor shall be conclusive in the absence of
demonstrable error.  In determining such amount, a Lender may use any
reasonable averaging and attribution methods.  If a Lender demands compensation
under this Section 8.03, Company may at any time, upon at least five Business
Days' prior notice to such Lender, after reimbursement to such Lender by
Company in accordance with this Section 8.03 of all costs incurred, prepay in
full the then outstanding LIBOR Advances or Eurocurrency Advance, as
appropriate, of such Lender, together with accrued interest thereon to the date
of prepayment, along with any reimbursement required under Section 2.09.
Concurrently with prepaying such LIBOR Advances or Eurocurrency Advances, as
appropriate, made by Lenders, Company may borrow a Base Rate Advance from such
Lender, and such Lender shall make such Base Rate Advance, in an amount such
that the outstanding principal amount of the Advances owing to such Lender
shall equal the outstanding principal amount of the Advances owing immediately
prior to such prepayment.

         8.04.   Base Rate Advances Rather than LIBOR Advances or Eurocurrency
Advances.  If notice has been given pursuant to Section 8.01, 8.02 or 8.03
suspending the obligation of a Lender to make LIBOR Advances or Eurocurrency
Advances, as appropriate, or requiring LIBOR Advances or Eurocurrency Advances,
as appropriate, of a Lender to be repaid or prepaid, then, unless and until
such Lender notifies Company that the circumstances giving rise to such
repayment no longer apply, all Advances which would otherwise be made by such
Lender to Company as LIBOR Advances or Eurocurrency Advances, as appropriate,
shall be made instead as Base Rate Advances.

         8.05.   Capital Adequacy.  If either (a) the introduction of or any
change in or in the interpretation of any Law or (b) compliance by a Lender
with any Law or any guideline or request from any central bank or other
Tribunal (whether or not having the force of law) affects or would affect the
amount of capital required or expected to be maintained by a Lender or any
corporation controlling such Lender, and such Lender determines that the amount
of such capital is increased by or based upon the existence of such Lender's
commitments or Advances hereunder and other commitments or advances of such
Lender of this type, then, upon demand by such Lender, subject to Section
10.09, Company shall immediately pay to such Lender, from time to time as
specified by such Lender, additional amounts sufficient to compensate such
Lender with respect to such circumstances, to the extent that such Lender
reasonably determines in good faith such increase in capital to be allocable to
the existence of such Lender's commitment hereunder.  A certificate as to such
amounts submitted to Company by a Lender hereunder, shall, in the absence of
demonstrable error, be conclusive and binding for all purposes.  The failure of
any Lender to demand compensation hereunder shall not constitute a waiver of
such Lender's rights to demand such compensation.  Without prejudice to the
survival of any other obligations of Company hereunder, the obligations of
Company under this Section 8.05 shall survive the payment of the Obligations
and termination of this Agreement.


ARTICLE IX.  AGREEMENT AMONG LENDERS

         9.01.   Agreement Among Lenders.  Lenders agree among themselves that:

         (a)     Administrative Lender.  Each Lender hereby appoints
Administrative Lender as its nominee in its name and on its behalf, to receive
all documents and items to be furnished hereunder; to act as nominee for and on
behalf of all Lenders under the Loan Documents; to, except as otherwise
expressly set forth herein, take such action as may be requested by Determining
Lenders or the Required Lenders, as appropriate, provided that, unless and
until Administrative Lender shall have received such requests, Administrative
Lender may take such administrative action, or refrain from taking such
administrative action, as it may deem advisable and in the best interests of
Lenders; to arrange the means whereby the proceeds of the Advances of Lenders
are to be made available to Company; to distribute promptly to each Lender
information, requests and documents received from any Loan Party, and each
payment (in like funds received) with respect to any of such Lender's Advances,
fee or other amount; and to deliver to any Loan Party requests, demands,
approvals and consents received from Lenders.  Administrative Lender agrees to
promptly distribute to each Lender, at such Lender's address set forth on
Schedule 2.11 information, requests, documents and payments received from any
Loan Party.

         (b)     Replacement of Administrative Lender.  Should Administrative
Lender or any successor Administrative Lender ever cease to be a Lender
hereunder, or should Administrative Lender or any successor Administrative
Lender ever resign as Administrative Lender, or should Administrative Lender or
any successor Administrative Lender ever be removed with cause by Determining
Lenders, then the Lender appointed by the other Lenders, with the consent of





                                     - 71 -
<PAGE>   78
Company, shall forthwith become Administrative Lender, and Company and Lenders
shall execute such documents as any Lender may reasonably request to reflect
such change.  Any resignation or removal of Administrative Lender or any
successor Administrative Lender shall become effective upon the appointment by
Lenders, with the consent of Company, of a successor Administrative Lender;
provided, however, that if Lenders fail for any reason to appoint a successor
within sixty days after the resigning Administrative Lender's giving notice of
resignation or Determining Lenders' removal of Administrative Lender,
Administrative Lender or any successor Administrative Lender (as the case may
be) may, on behalf of Lenders, appoint a successor Administrative Lender, which
shall be a commercial bank organized under the Laws of the United States of
America or of any state thereof and having a combined capital and surplus of at
least $10,000,000, and the resigning Administrative Lender shall thereafter
have no obligation to act as Administrative Lender hereunder.

         (c)     Expenses.  Each Lender shall pay its pro rata share, based on
its Sharing Ratio, of any expenses paid by Administrative Lender directly and
solely in connection with any of the Loan Documents if Administrative Lender
does not receive reimbursement therefor from other sources within sixty days
after the date incurred, unless payment of such fees is being diligently
disputed by such Lender or Company in good faith.  Any amount so paid by
Lenders to Administrative Lender shall be returned by Administrative Lender pro
rata to each paying Lender to the extent later paid by Company or any other
Person on Company's behalf to Administrative Lender.

         (d)     Delegation of Duties.  Administrative Lender may execute any
of its duties hereunder by or through officers, directors, employees, attorneys
or agents, and shall be entitled to (and shall be protected in relying upon)
advice of counsel concerning all matters pertaining to its duties hereunder.

         (e)     Reliance by Administrative Lender.  Administrative Lender and
its officers, directors, employees, attorneys and agents shall be entitled to
rely and shall be fully protected in relying on any writing, resolution,
notice, consent, certificate, affidavit, letter, cablegram, telegram, telex or
teletype message, statement, order, or other document or conversation
reasonably believed by it or them in good faith to be genuine and correct and
to have been signed or made by the proper Person and, with respect to legal
matters, upon opinions of counsel selected Administrative Lender.
Administrative Lender may, in its reasonable judgment, deem and treat the payee
of any Note as the owner thereof for all purposes hereof.

         (f)     Limitation of Administrative Lender's Liability.  Neither
Administrative Lender nor any of its Affiliates, officers, directors,
employees, attorneys or agents shall be liable for any action taken or omitted
to be taken by it or them hereunder in good faith and believed by it or them to
be within the discretion or power conferred to it or them by the Loan Documents
or be responsible for the consequences of any error of judgment, except for its
or their own gross negligence or wilful misconduct.  Except as aforesaid,
Administrative Lender shall not be under any duty to enforce any rights with
respect to any of the Advances, Letters of Credit, or any security therefor.
Administrative Lender shall not be compelled to do any act hereunder or





                                     - 72 -
<PAGE>   79
to take any action towards the execution or enforcement of the powers hereby
created or to prosecute or defend any suit in respect hereof, unless
indemnified to its satisfaction against loss, cost, liability and expense.
Administrative Lender shall not be responsible in any manner to any Lender or
Issuing Bank for the effectiveness, enforceability, genuineness, validity or
due execution of any of the Loan Documents, or for any representation,
warranty, document, certificate, report or statement made herein or furnished
in connection with any Loan Documents, or be under any obligation to any Lender
or Issuing Bank to ascertain or to inquire as to the performance or observation
of any of the terms, covenants or conditions of any Loan Documents on the part
of any Loan Party.  To the extent not reimbursed by Loan Parties, each Lender
hereby jointly and severally indemnifies and holds harmless Administrative
Lender, pro rata according to its Sharing Ratio, from and against any and all
liabilities, obligations, losses, damages, penalties, actions, judgments,
suits, costs, expenses and/or disbursements of any kind or nature whatsoever
which may be imposed on, asserted against, or incurred by Administrative Lender
(in its capacity as Administrative Lender and not as a Lender or Issuing Bank)
in any way with respect to any Loan Documents or any action taken or omitted by
Administrative Lender (in its capacity as Administrative Lender and not as a
Lender or Issuing Bank) under the Loan Documents (including any negligent
action of Administrative Lender), except to the extent the same result from
gross negligence or wilful misconduct by Administrative Lender.  The
obligations of Loan Parties and Lenders under this Section 9.01(h) shall
survive termination of this Agreement and any resignation or removal of
Administrative Lender.

         (g)     Liability Among Lenders.  No Lender shall incur any liability
(other than the sharing of expenses and other matters specifically set forth
herein and in the other Loan Documents) to any other Lender, except for acts or
omissions in bad faith.

         (h)     Rights as Lender.  With respect to its obligations in respect
of the Commitment, the Advances made by it and Note issued to it,
Administrative Lender and Issuing Bank shall have the same rights as a Lender
and may exercise the same as though it were not Administrative Lender or
Issuing Bank and the term "Lender" or "Lenders" shall, unless the context
otherwise indicates, include Administrative Lender and Issuing Bank in their
respective individual capacities.  Administrative Lender, Issuing Bank or any
Lender may accept deposits from, act as trustee under indentures of, and
generally engage in any kind of business with, Company and any of its
Affiliates, and any Person who may do business with or own securities of
Company or any of its Affiliates, all as if Administrative Lender and Issuing
Bank were not Administrative Lender or Issuing Bank, respectively, hereunder
and without any duty to account therefor to Lenders.

         9.02.   Lender Credit Decision.  Each Lender acknowledges that it has,
independently and without reliance upon Administrative Lender, Issuing Bank or
any other Lender and based upon the financial statements referred to in
Sections 4.04, 5.01(a) and 5.01(b), and such other documents and information as
it has deemed appropriate, made its own credit analysis and decision to enter
into this Agreement.  Each Lender also acknowledges that it will, independently
and without reliance upon Administrative Lender, Issuing Bank or any other
Lender and based upon such documents and information as it shall deem
appropriate at the time, continue to make





                                     - 73 -
<PAGE>   80
its own credit decisions in taking or not taking action under this Agreement
and the other Loan Documents.

         (b)     Any party hereto may change the address to which notices shall

         10.02.  Expenses.  Company shall promptly pay:





                                     - 74 -
<PAGE>   81
         (a)     all reasonable out-of-pocket expenses of Administrative Lender
in connection with the preparation, negotiation, execution and delivery of this
Agreement and the other Loan Documents, the transactions contemplated hereunder
and thereunder, and the making of Advances and the issuance of Letters of
Credit hereunder, including, without limitation, the reasonable fees of and the
out-of-pocket expenses incurred by Special Counsel;

         (b)     all reasonable out-of-pocket expenses and attorneys' fees of
Administrative Lender in connection with the administration of the transactions
contemplated in this Agreement and the other Loan Documents and the
preparation, negotiation, execution and delivery of any waiver, amendment or
consent by Lenders relating to this Agreement or the other Loan Documents; and

         (c)     (i) all costs, out-of-pocket expenses and attorneys' fees of
Administrative Lender incurred for enforcement, collection, restructuring,
refinancing and "work-out", or otherwise incurred in obtaining performance
under the Loan Documents, which in each case shall include, without limitation,
fees and expenses of counsel for Administrative Lender, and administrative fees
for Administrative Lender, (ii) after the occurrence of an Event of Default
specified in Section 6.01(a), all costs, out-of-pocket expenses and attorneys'
fees of each Lender incurred for enforcement, collection, restructuring,
refinancing and "work-out", or otherwise incurred in obtaining performance
under the Loan Documents, and all costs and out-of-pocket expenses of
collection, which in each case shall include, without limitation, fees and
expenses of consultants and counsel for each Lender, and (iii) after the
occurrence of an Event of Default other than that specified in Section 6.01(a),
all non-legal out-of-pocket expenses of each Lender and all attorneys' fees of
one counsel acting on behalf of all Lenders incurred for enforcement,
restructuring, refinancing and "work-out", or otherwise incurred in obtaining
performance under the Loan Documents.

         10.03.  Waivers.  The rights and remedies of Administrative Lender,
Issuing Bank, and Lenders under this Agreement and the other Loan Documents
shall be cumulative and not exclusive of any rights or remedies which they
would otherwise have.  No failure or delay by Administrative Lender, Issuing
Bank, or any Lender in exercising any right shall operate as a waiver of such
right.  Lenders expressly reserve the right to require strict compliance with
the terms of this Agreement in connection with any funding of a request for an
Advance and Issuing Bank expressly reserves the right to require strict
compliance with the terms of this Agreement in connection with any issuance of
a Letter of Credit.  In the event that any Lender decides to fund an Advance or
Issuing Bank decides to issue a Letter of Credit at a time when a Loan Party is
not in strict compliance with the terms of this Agreement, such decision by
such Lender or Issuing Bank shall not be deemed to constitute an undertaking by
such Lender to fund any further requests for Advances or by Issuing Bank to
issue any additional Letters of Credit or preclude Administrative Lender,
Issuing Bank or Lenders from exercising any rights available under the Loan
Documents or at law or equity.  Any waiver or indulgence granted by
Administrative Lender, Issuing Bank or Lenders shall not constitute a
modification of this Agreement, except to the extent expressly provided in such
waiver or indulgence, or constitute a course of dealing by Administrative
Lender, Issuing Bank or Lenders at variance with the terms of the Agreement
such as to require further notice by Administrative Lender, Issuing Bank





                                     - 75 -
<PAGE>   82
or Lenders of Administrative Lender's, Issuing Bank's or any Lender's intent to
require strict adherence to the terms of the Agreement in the future.  Any such
actions shall not in any way affect the ability of Administrative Lender,
Issuing Bank, or any Lender, in their discretion, to exercise any rights
available to them under this Agreement or under any other agreement, whether or
not Administrative Lender, Issuing Bank, or any Lender is a party thereto,
relating to any Loan Party.

         10.04.  Determination by Lenders Conclusive and Binding.  Any material
determination required or expressly permitted to be made by Administrative
Lender, Issuing Bank, or any Lender under this Agreement shall be made in its
reasonable judgment and in good faith, and shall when made, absent demonstrable
error, be conclusive and binding on all parties.

         10.05.  Set-Off.  Upon the occurrence and continuance of an Event of
Default and acceleration of the Notes and Obligations, each Lender and any
subsequent holder of any Note, and any assignee in any Note is hereby
authorized by each Loan Party at any time or from time to time to set-off,
appropriate and apply any deposits (general or special (except trust and escrow
accounts), time or demand, including without limitation debt evidenced by
certificates of deposit, in each case whether matured or unmatured) and any
other debt at any time held or owing by such Lender or holder to or for the
credit or the account of any Loan Party, against and on account of the
Obligations and other liabilities of any Loan Party to such Lender or holder,
irrespective of whether or not the Lender or holder shall have made any demand
hereunder (other than as expressly provided in Section 6.02) and although
certain of such obligations and liabilities, or any of them, shall be
contingent.  Any sums obtained by any Lender or by any assignee or subsequent
holder of any Note shall be subject to pro rata treatment of all Obligations
and other liabilities hereunder.  Each Lender agrees promptly to notify any
Loan Party after any such set-off and application by such Lender, but the
failure to give such notice shall not affect the validity of such set-off and
application.

         10.06.  Assignment.

         (a)     No Loan Party may assign or transfer any of its rights or
obligations hereunder or under the other Loan Documents without the prior
written consent of Lenders.

         (b)     No Lender shall be entitled to assign its interest in this
Agreement, its Notes or its Advances, except as hereinafter set forth.

         (c)     Without the consent of Company, any Lender may at any time
sell participations in all or any part of its Advances and Reimbursement
Obligations (collectively, "Participations") to any banks or other financial
institutions ("Participants") provided that neither such Participation nor any
agreement relating thereto shall confer on any Person (other than the parties
hereto) any right to vote on, approve or sign amendments or waivers, or any
other independent benefit or any legal or equitable right, remedy or other
claim under this Agreement or any other Loan Documents, other than the right to
vote on, approve, or sign amendments or waivers or consents with respect to
items that would result in (i) any increase in the commitment





                                     - 76 -
<PAGE>   83
of any Participant; or (ii)(A) the extension of the date of maturity of, or (B)
the extension of the due date for any payment of principal, interest or fees
respecting, or (C) the reduction of the amount of any installment of principal
or interest on or the change or reduction of any mandatory reduction required
hereunder, or (D) a reduction of the rate of interest on, the Advances, the
Letters of Credit, or the Reimbursement Obligations to which such Participant
is entitled; or (iii) the release of security for the Obligations, including
without limitation any guarantee, except pursuant to this Agreement; or (iv)
the reduction of any fees payable hereunder to which such Participant is
entitled.  Lenders may, subject to Section 10.13, provide copies of all
financial information received from Company to such Participants.

         (d)     Each Lender may assign to one or more financial institutions
or funds organized under the laws of the United States, or any state thereof,
or under the laws of any other country that is a member of the Organization for
Economic Cooperation and Development, or a political subdivision of any such
country, which is engaged in making, purchasing or otherwise investing in
commercial loans in the ordinary course of its business (each, an "Assignee")
its rights and obligations under this Agreement and the other Loan Documents;
provided, however, that (i) each such assignment shall be subject to the prior
written consent of Administrative Lender and Company, which consent shall not
be unreasonably withheld, (ii) each such assignment shall be of a constant, and
not a varying, percentage of such Lender's rights and obligations under this
Agreement, (iii) the amount of the Advances and Reimbursement Obligations being
assigned pursuant to each such assignment (determined as of the date of the
assignment with respect to such assignment) shall in no event be less than the
lesser of (A) $10,000,000 (or the Eurocurrency equivalent), or (B) the
applicable Lender's portion of the Commitment, (iv) the applicable Lender,
Administrative Lender, and applicable Assignee shall execute and deliver to
Administrative Lender an Assignment and Acceptance Agreement (an "Assignment
Agreement") in substantially the form of Exhibit C, together with the Notes
subject to such assignment, (v) the Assignee or the Lender executing the
Assignment Agreement as the case may be, shall deliver to Administrative Lender
a processing fee of $3,500, and (vi) Administrative Lender shall give Company
notice of any proposed assignment no later than thirty days prior to any
assignment by any Lender.  Upon such execution, delivery and acceptance from
and after the effective date specified in each Assignment Agreement, which
effective date shall be at least three Business Days after the execution
thereof, (A) the Assignee thereunder shall be party hereto and, to the extent
that rights and obligations hereunder have been assigned to it pursuant to such
Assignment, have the rights and obligations of a Lender hereunder and (B) the
assigning Lender shall, to the extent that rights and obligations hereunder
have been assigned by it pursuant to such Assignment Agreement, relinquish such
rights and be released from such obligations under this Agreement.

         (e)     Notwithstanding anything in Section 10.06(d) to the contrary,
any Lender may assign and pledge all or any portion of its Advances and Notes
to any Federal Reserve Bank as collateral security pursuant to Regulation A of
F.R.S. Board and any Operating Circular issued by such Federal Reserve Bank;
provided, however, that no such assignment under this Section 10.06(e) shall
release the assignor Lender from its obligations hereunder.





                                     - 77 -
<PAGE>   84
         (f)     Upon its receipt of an Assignment Agreement executed by a
Lender and an Assignee, and any Note or Notes subject to such assignment,
Company shall, within three Business Days after its receipt of such Assignment
Agreement, at its own expense, execute and deliver to Administrative Lender, in
exchange for the surrendered Notes, new Notes to the order of such Assignee in
an amount equal to the portion of the Commitment assigned to it pursuant to
such Assignment Agreement and new Notes to the order of the assigning Lender in
an amount equal to the portion of the Advances and Commitment retained by it
hereunder.  Such new Notes shall be in an aggregate principal amount equal to
the aggregate principal amount of such surrendered Notes, shall be dated the
effective date of such Assignment Agreement and shall otherwise be in
substantially the form of Exhibit A.

         (g)     Any Lender may, in connection with any assignment or proposed
assignment pursuant to this Section 10.06, disclose to the Assignee or proposed
Assignee, any information relating to Loan Parties furnished to such Lender by
or on behalf of any Loan Party.

         (h)     Except as specifically set forth in this Section 10.06,
nothing in this Agreement or any other Loan Documents, expressed or implied, is
intended to or shall confer on any Person other than the respective parties
hereto and thereto and their successors and Assignees permitted hereunder and
thereunder any benefit or any legal or equitable right, remedy or other claim
under this Agreement or any other Loan Documents.

         (i)     Notwithstanding anything in this Section 10.06 to the
contrary, no Assignee shall be entitled to receive any greater payment under
Section 2.15 or Section 8.03 than such assigning Lender would have been
entitled to receive with respect to the interest assigned to such Assignee.

         10.07.  Counterparts.  This Agreement may be executed in any number of
counterparts, each of which shall be deemed to be an original, but all such
separate counterparts shall together constitute but one and the same
instrument.

         10.08.  Severability.  Any provision of this Agreement which is for
any reason prohibited or found or held invalid or unenforceable by any court or
governmental agency shall be ineffective to the extent of such prohibition or
invalidity or unenforceability without invalidating the remaining provisions
hereof in such jurisdiction or affecting the validity or enforceability of such
provision in any other jurisdiction.

         10.09.  Interest and Charges.  It is not the intention of any parties
to this Agreement to make an agreement in violation of the Laws of any
applicable jurisdiction relating to usury.  Regardless of any provision in any
Loan Documents, no Lender shall ever be entitled to receive, collect or apply,
as interest on the Obligations, any amount in excess of the Maximum Amount.  If
any Lender ever receives, collects or applies, as interest, any such excess,
such amount which would be excessive interest shall be deemed a partial
repayment of principal and treated hereunder as such; and if principal is paid
in full, any remaining excess shall be paid to Company.  In determining whether
or not the interest paid or payable, under any





                                     - 78 -
<PAGE>   85
specific contingency, exceeds the Maximum Amount, Loan Parties and Lenders
shall, to the maximum extent permitted under Applicable Law, (a) characterize
any nonprincipal payment as an expense, fee or premium rather than as interest,
(b) exclude voluntary prepayments and the effect thereof, and (c) amortize,
prorate, allocate and spread in equal parts, the total amount of interest
throughout the entire contemplated term of the Obligations so that the interest
rate is uniform throughout the entire term of the Obligations; provided,
however, that if the Obligations are paid and performed in full prior to the
end of the full contemplated term thereof, and if the interest received for the
actual period of existence thereof exceeds the Maximum Amount, Lenders shall
refund to Company the amount of such excess or credit the amount of such excess
against the total principal amount of the Obligations owing, and, in such
event, Lenders shall not be subject to any penalties provided by any laws for
contracting for, charging or receiving interest in excess of the Maximum
Amount.  This Section 10.09 shall control every other provision of all
agreements pertaining to the transactions contemplated by or contained in the
Loan Documents.

         10.10.  Headings.  Headings used in this Agreement are for convenience
only and shall not be used in connection with the interpretation of any
provision hereof.

         10.11.  Amendment and Waiver.  The provisions of this Agreement may
not be amended, modified or waived except by the written agreement of Loan
Parties and Determining Lenders; provided, however, that no such amendment,
modification or waiver shall be made (a) without the consent of all Lenders, if

reasonable precautions to keep confidential, in accordance with customary
procedures for handling confidential information of this nature and in

supplied to it by any Loan Party pursuant to this Agreement which is identified

         10.14.  Judgment.

         (a)     If for the purposes of obtaining judgment in any court it is
necessary to convert a sum due hereunder or under the Notes in any currency
(the "Original Currency") into another currency (the "Other Currency") the
parties hereto agree, to the fullest extent that they may effectively do so,
that the rate of exchange used shall be that at which in accordance with normal
banking procedures Administrative Lender could purchase the Original Currency
with the Other Currency at 11:00 a.m. on the third Business Day preceding that
on which final judgment is given.

         (b)     The obligation of any Loan Party in respect of any sum due in
the Original Currency from it to any Lender or Administrative Lender hereunder
or under the Note held by such shall, notwithstanding any judgment in any Other
Currency, be discharged only to the extent that on the Business Day following
receipt by such Lender or Administrative Lender (as the case may be) of any sum
adjudged to be so due in such Other Currency such Lender or Administrative
Lender (as the case may be) may in accordance with normal banking procedures
purchase Dollars with such Other Currency; if the amount of the Original
Currency so purchased is less than the sum originally due to such Lender or
Administrative Lender (as the case may be) in the Original Currency, each Loan
Party, jointly and severally, agrees, as a separate obligation and
notwithstanding any such judgment, to indemnify such Lender or Administrative
Lender (as the case may be) against such loss, and if the amount of the
Original Currency so purchased exceeds the sum originally due to any Lender or
Administrative Lender (as the case may be) in the Original Currency, such
Lender or Administrative Lender (as the case may be) agrees to remit to Company
such excess.

         10.15.  GOVERNING LAW.  THIS AGREEMENT AND THE OTHER LOAN DOCUMENTS

Lender its Pro Rata Share of any such payment received by Administrative
Lender, or any such application made by Administrative Lender, such payment or
application is rescinded or must otherwise be returned or must be paid over by
Administrative Lender for any reason, such Lender shall, upon notice by
