NOTE 1 - GENERAL:

The accompanying unaudited consolidated financial statements of PETsMART, Inc.
and Subsidiaries ("PETsMART" or "Company") have been prepared in accordance with
generally accepted accounting principles for interim financial information.
Accordingly, they do not include all of the information and footnotes required
by generally accepted accounting principles for financial statements. All
adjustments, consisting of normal recurring adjustments, that in the opinion of
management are necessary for a fair presentation have been included.

Because of the seasonal nature of the Company's business, the results of
operations for the thirteen weeks ended May 2, 1999 and May 3, 1998 are not
necessarily indicative of the results to be expected for the full year. For
further information, refer to the consolidated financial statements and
footnotes thereto for the fiscal year ended January 31, 1999, included in the
Company's Annual Report on Form 10-K (File No. 0-21888) filed with the
Securities and Exchange Commission on April 26, 1999.


NOTE 2 - CHANGE IN ACCOUNTING PRINCIPLE:

In April 1998, the AICPA issued Statement of Position 98-5, "Reporting on the
Costs of Start-up Activities" ("SOP-98-5"). SOP 98-5 is effective for financial
statements for fiscal years beginning after December 15, 1998. Under the
provisions of SOP 98-5, costs of start-up activities, including organization
costs, should be expensed as incurred. The Company adopted SOP 98-5 at the
beginning of the first quarter of fiscal 1999. Prior to its adoption of SOP
98-5, the Company expensed its store preopening costs in the month in which the
store opened. The charge against earnings during the first quarter of fiscal
1999 related to this change in accounting principle was $888,000, before taxes,
and was recorded as a cumulative effect of a change in accounting principle.


NOTE 3 - COMPREHENSIVE INCOME:

The income tax expense (benefit) related to items of other comprehensive income
was approximately $(656,000) and $639,000 for first quarter 1999 and 1998,
respectively.


NOTE 4 - EARNINGS PER SHARE:

Basic earnings per share are computed by dividing net income by the weighted
average of common shares outstanding during each period. Diluted earnings per
share is computed by dividing net income by the weighted average number of
common shares outstanding during the period after giving effect to dilutive
stock options and dilutive common shares assumed to be issued on conversion of
PETsMART's subordinated convertible notes.

At May 2, 1999, no shares of common stock had been issued upon conversion of the
subordinated convertible notes issued in November 1997. These notes are
convertible into an aggregate of approximately 22.8 million shares of common
stock. These shares were not included in the calculation of diluted earnings per
share for the thirteen weeks ended May 2, 1999 or May 3, 1998 due to the
anti-dilutive effect they would have on earnings per share if converted.


NOTE 5 - RECENTLY ISSUED ACCOUNTING PRONOUNCEMENTS:

In June 1998, the Financial Accounting Standards Board issued Statement of
Financial Accounting Standards No. 133, "Accounting for Derivative Instruments
and Hedging Activities" ("SFAS 133"). SFAS 133 is effective for financial
statements for fiscal years beginning after June 15, 1999. This statement
establishes the accounting and reporting standards for derivative instruments
and hedging activities, requiring that an entity recognize all derivatives as
either assets or liabilities in the statement of financial position and measure
them at fair value. It also provides for matching of the timing of gain or loss
recognition on the hedging instrument with the recognition of (i) the changes in
the fair value of the hedged asset or liability related to the hedged risk or
(ii) the hedged forecasted transaction earnings effect. The Company will adopt
SFAS 133 in the first quarter of fiscal 2000 and does not expect a material
effect on its financial statements as a result of adoption.

ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
OF OPERATIONS

      Except for the historical information contained herein, the following
discussion contains forward-looking statements that involve risks and
uncertainties. The Company's actual results could materially differ from those
discussed here. Factors that could cause or contribute to such differences
include, but are not limited to, those discussed in this section, as well as in
the sections entitled Distribution, Information Systems, Competition, and
Business Risks included in the Company's Form 10-K for the year ended January
31, 1999.

OVERVIEW

      PETsMART is the largest operator of superstores specializing in pet food,
supplies and services in North America and the United Kingdom. At May 2, 1999,
the Company operated 558 superstores, consisting of 444 superstores in the
United States, 95 superstores in the United Kingdom, and 19 superstores in
Canada. PETsMART's store base has grown rapidly since the Company's inception in
1986 through the opening of new stores and through the acquisitions of PETZAZZ
in March 1994, Petstuff in June 1995, Pet Food Giant in September 1995, and Pet
City in December 1996. The Company also acquired two leading catalog retailers,
Sporting Dog Specialties in May 1995 and State Line Tack in January 1996. All of
these transactions were accounted for as poolings of interest.

      The Company expects that future increases in net sales and net income, if
any, will be dependent on the opening of additional superstores and the improved
performance of existing superstores. In view of the increasing maturity of its
superstore base, as well as the planned opening of additional superstores in
existing markets and single-store markets, the Company's comparable store sales
increases may be lower in future periods. As a result of its expansion plans,
the Company anticipates the timing of new superstore openings, and related
preopening expenses, and the amount of revenue contributed by new and existing
superstores may cause the Company's quarterly results of operations to
fluctuate. The Company has achieved less favorable operating results in certain
North American geographic regions it recently entered than it has achieved
historically in other regions. In addition, because new superstores have higher
payroll, advertising and other store level expenses as a percentage of sales
than mature superstores, the impact of new superstore openings will also
contribute to lower store operating margins until they become established.
Commencing with the first quarter of fiscal 1999, the Company charges preopening
costs associated with each new superstore to earnings as the costs are incurred.
Therefore, the Company expects that the opening of large numbers of new
superstores in a given quarter will adversely impact its quarterly results of
operations for that period.

</TABLE>


FIRST QUARTER FISCAL 1999 COMPARED TO FIRST QUARTER FISCAL 1998

      Net sales increased 13.6% to approximately $564.1 million for the thirteen
weeks ended May 2, 1999 from $496.6 million for the thirteen weeks ended May 3,
1998. Comparable North American store sales increased 4.5% for the quarter, and
comparable United Kingdom store sales increased 1.5%. During first quarter 1999,
the Company opened 26 new superstores, relocated one store, and closed four
stores in North America and opened two new superstores in the United Kingdom.
The Company operated 558 superstores at May 2, 1999 compared to 499 superstores
open at May 3, 1998.

      Gross profit, defined as net sales less cost of sales, including
distribution costs and store occupancy costs, increased as a percentage of net
sales from 24.6% for first quarter 1998 to 25.2% in first quarter 1999. This
result principally reflected improved product margins and sales mix changes
towards higher margin items, offset partially by increased warehouse and
distribution costs and increased occupancy costs.

      Store operating expenses, which includes payroll and benefits, advertising
and other store level expenses, decreased as a percentage of sales to 19.6% for
first quarter 1999 from 19.7% for first quarter 1998. The decrease reflected the
Company's planned efforts to lower equipment expenses through purchases of,
rather than lease of, certain equipment.

      Store preopening expenses as a percentage of net sales decreased to 0.4%
for first quarter 1999, compared to 0.9% for first quarter 1998. A portion of
first quarter 1999's preopening expenses were recorded as a cumulative effect of
a change in accounting principle, which affected the year-over-year
comparability of the store preopening expense component of the Company's
Consolidated Statements of Operations. For the stores that opened during the
first quarter 1999, the average preopening expense incurred was approximately
$95,000 per store, which is consistent with the Company's prior experience.
Including one North American replacement store and two new United Kingdom
stores, 28 stores were opened during first quarter 1999.


                                       11
<PAGE>   12
      General and administrative expenses as a percentage of sales increased
from 3.0% for first quarter 1998 to 3.2% for first quarter 1999. This increase
was due to planned salary, compensation, and training costs associated with the
implementation of the Company's new management information systems. Certain of
these training expenditures will continue throughout the balance of the 1999
fiscal year as these systems are installed and integrated.

      The Company's operating income increased to $11.5 million for first
quarter 1999 from $5.0 million for first quarter 1998. Operating income as a
percentage of net sales increased from 1.0% for first quarter 1998 to 2.0% for
first quarter 1999. This increase was primarily due to improved product margins
and store expense control.

      Interest income increased to $1.3 million for first quarter 1999 from $0.5
million for first quarter 1998 principally due to the increase in average cash
balances available for short-term investment. Interest expense increased to $6.0
million for the first quarter 1999 from $5.3 million for first quarter 1998. The
increase in interest expense was due to unfavorable spreads between the
company's interest rate swap agreements and market interest rates, and capital
lease cost.


      For first quarter 1999, income taxes were provided at an annual effective
rate of 40.5%, compared to 38.5% for first quarter 1998. The increase in the
effective tax rate was caused by changes in foreign tax rates and mix of foreign
and domestic taxable income or loss.

      In April 1998, the AICPA issued Statement of Position 98-5, "Reporting on
the Costs of Start-up Activities" ("SOP-98-5"). SOP 98-5 is effective for
financial statements for fiscal years beginning after December 15, 1998. Under
the provisions of SOP 98-5, costs of start-up activities, including organization
costs, should be expensed as incurred. The Company adopted SOP 98-5 at the
beginning of the first quarter of fiscal 1999. Prior to its adoption of SOP
98-5, the Company expensed its store preopening costs in the month in which the
store opened. The charge against earnings during the first quarter of fiscal
1999 related to this change in accounting principle was $0.9 million, before
taxes, and was recorded as a cumulative effect of a change in accounting
principle.

      As a result of the foregoing, the Company reported net income before
cumulative effect of a change in accounting principle of $4.1 million (or $0.03
per share - diluted) for first quarter 1999 compared to net income of $0.2
million (or $0.00 per share - diluted) for first quarter 1998.

LIQUIDITY AND CAPITAL RESOURCES

      The Company has financed its operations and expansion program to date
principally through cash flows from operations, the sale of equity and debt
securities, lease financing and borrowings under its credit facility. Additional
sources of financing have included vendor terms on inventory purchases.

      In November 1997, $200,000,000 of 6-3/4% Subordinated Convertible Notes
(the "Notes") were issued by the Company and sold to "qualified institutional
buyers" as defined in Rule 144A of the Securities Act of 1933, as amended (the
"Securities Act") in transactions exempt from registration under the Securities
Act, and in sales outside the United States within the meaning of Regulation S
under the Securities Act. The net proceeds to PETsMART from the sale of the
Notes were approximately $193,250,000.

      On June 1, 1999, the Company announced that its Board of Directors had
approved a program to repurchase up to an aggregate of $25,000,000 of its Common
Stock. The repurchases may be made from time to time on the open market at
prevailing market prices or in negotiated transactions off the market. The
repurchase program is expected to continue through the end of the 1999 fiscal
year unless extended or shortened by the Company's Board of Directors.

      At May 2, 1999, total assets were $924.9 million, of which $540.2 million
were current assets. Cash and cash equivalents were $120.2 million.

      Cash used in operations was $11.7 million for the thirteen weeks ended May
2, 1999, compared to cash used in operations of $16.0 million for the same
period of the prior year. Merchandise accounts payable leveraging (the
percentage of merchandise inventory financed by vendor credit terms, e.g.,
accounts payable divided by merchandise inventory), decreased to 39.9% at May 2,
1999, compared to 44.3% at January 31, 1999. Inventory balances were
approximately $356.2 million at May 2, 1999, and $336.1 million at January 31,
1999. Average North American store inventory, which excludes the inventory of
PETsMART DIRECT, increased 1.1% to approximately $667,000 per store at May 2,
1999, from approximately $660,000 at January 31, 1999. This increase reflected
the planned inventory purchases required for the addition of the Nutro brand
product line into stores at the beginning of the second quarter of 1999.

      The Company uses cash in investing activities to purchase leaseholds,
fixtures and equipment for new superstores and, to a lesser extent, to purchase
equipment and computer software in support of its systems initiatives. The
Company also uses cash to purchase superstores for sale and leaseback. Net cash
used in investing activities was $18.8 million for the thirteen weeks ended May
2, 1999, compared to $15.5 million used for the thirteen weeks ended May 3,
1998.

      Net cash used in financing activities, primarily the change in the
Company's bank overdraft and principal payments on capital leases, net of
proceeds from the exercise of employee stock options, was $1.6 million for the
thirteen weeks ended May 2, 1999. Net cash of $4.9 million was provided by these
activities, net, during the thirteen weeks ended May 3, 1998.

      The Company's primary long-term capital requirements are for opening new
superstores, the costs of closing redundant or inadequate superstores, corporate
investment, including costs associated with the development and implementation
of the Company's new information system, and for working capital.

      All of the Company's superstores are leased facilities. The Company
estimates that the cash requirements after lease financing to open each new U.S.
prototype superstore, including store fixtures and equipment, leasehold
improvements, preopening costs and inventory is approximately $975,000. This
amount will typically include an average of approximately $50,000 for leasehold
improvements (an average of approximately $400,000 if the superstore site is a
rehabilitated unit), approximately $100,000 for preopening costs, and
approximately $375,000 for inventory, net of accounts payable. Approximately
$450,000 is required for store fixtures and equipment.

      The Company has begun to open 19,000 square foot superstore locations,
primarily in single-store markets and as fill-in locations in existing markets.
The Company expects that these smaller stores will comprise a growing percentage
of its new store locations in future years as the Company's real estate strategy
matures. These locations are generally leased facilities and cash requirements
for these locations will typically include approximately $325,000 for inventory,
net of accounts payable, approximately $100,000 for preopening costs, and an
average of approximately $50,000 for leasehold improvements. Approximately
$375,000 is required for store fixtures and equipment.

      Based upon the Company's current plan to open approximately 30 new North
American stores during the remainder of fiscal 1999, approximately $29.3 million
will be needed to finance these openings. The Company may also expend additional
funds to take advantage of opportunities that arise from time to time for the
acquisition of businesses or lease rights from tenants occupying retail space
that is suitable for a PETsMART superstore.

      PETsMART is in the implementation stage of developing and implementing an
integrated North America information system which will feature a common set of
applications. The Company estimates that its costs in connection with the
development and implementation of the new system, before giving consideration to
any lease financing that may be available, will be up to $20 million annually
through fiscal 2000. The Company believes that certain hardware and software
components of the new system will be financed through lease transactions, some
of which have been completed. There can be no assurance that the actual costs
for the new system will not exceed current estimates, or that the new system can
be developed, tested and implemented on a timely basis, or at all, or that it
will deliver the anticipated operational benefits in a reliable manner. Failure
to complete the new system on a timely basis could materially adversely affect
the Company's future operating results or its ability to expand. In particular,
should the new system not be operational, or should an alternate solution not be
implemented by January 1, 2000, the Company may experience software difficulties
as a result of the "Year 2000" problem (see "Year 2000 Readiness"). In the event
that additional financing is required to complete the Company's new information
system, there can be no assurance that such additional financing will be
available to the Company on acceptable terms.


                                       13
<PAGE>   14
      Capital expenditures, net of construction allowances, were approximately
$19.0 million during the thirteen weeks ended May 2, 1999. Such expenditures
were used primarily for the opening of new superstores in North America and the
United Kingdom, the development and implementation of the Company's new
information system and the remodel and maintenance of the Company's existing
superstores.

      Management believes that its existing cash and cash equivalents, together
with cash flow from operations, borrowing capacity under its bank credit
facility and available lease financing will provide adequate funds for the
Company's foreseeable working capital needs, planned capital expenditures and
debt service obligations. The Company's ability to fund its operations and to
make planned capital expenditures and scheduled debt payments, to refinance
indebtedness and to remain in compliance with all of the financial covenants
under its debt agreements depends on its future operating performance and cash
flow, which in turn are subject to prevailing economic conditions and to
financial, business and other factors, some of which are beyond the Company's
control.

SEASONALITY AND INFLATION

      The Company's business is subject to some seasonal fluctuation and it
typically realizes a substantial portion of its net sales and operating profits
during the fourth fiscal quarter. In addition, sales of certain of the Company's
products and services designed to address pet health needs, such as flea and
tick problems, have been and may continue to be negatively impacted by the
introduction of alternative treatments, as well as by variations in weather
conditions. In addition, because PETsMART's superstores typically draw customers
from a large trade area, sales may be impacted by adverse weather or travel
conditions.

      The Company's results of operations and financial position are presented
based upon historical cost. Although the Company cannot accurately anticipate
the effect of inflation on its operations, it does not believe inflation is
likely to have a material adverse effect on its net sales or results of
operations.

RECENT ACCOUNTING PRONOUNCEMENTS

      In June 1998, the Financial Accounting Standards Board issued Statement of
Financial Accounting Standards No. 133, "Accounting for Derivative Instruments
and Hedging Activities" ("SFAS 133"). SFAS 133 is effective for financial
statements for fiscal years beginning after June 15, 1999. This statement
establishes the accounting and reporting standards for derivative instruments
and hedging activities, requiring that an entity recognize all derivatives as
either assets or liabilities in the statement of financial position and measure
them at fair value. It also provides for matching of the timing of gain or loss
recognition on the hedging instrument with the recognition of (i) the changes in
the fair value of the hedged asset or liability related to the hedged risk or
(ii) the hedged forecasted transaction earnings effect. The Company will adopt
SFAS 133 in the first quarter of fiscal 2000 and does not expect a material
effect on its financial statements as a result of adoption.

YEAR 2000 READINESS

      The Year 2000 systems processing problem, as it is commonly known, is
caused by currently utilized computer systems, including several used by the
Company, being coded to only accept two-digit codes for the year field in a date
set of data. Beginning in the year 2000, these date fields must be able to
accept four-digit entries to distinguish 1900 base-year dates with 2000
base-year dates. The Company is and has been addressing the Year 2000 systems
issue through various initiatives, all of which are in progress. A new
integrated North American information system, which is Year 2000 compliant, is
currently in the implementation stage. The system is scheduled to be operational
for the North American retail operations during the summer of 1999. Other
initiatives in place include issue awareness programs, inventory and
identification of all Year 2000-sensitive components (including hardware,
software, and telecommunications), requesting of compliance status statements
from Company business partners, suppliers, and vendors, and testing of all new
and existing systems. Year 2000 compliance activities are expected to be
complete by October 1999. The Company estimates that its costs in connection
with the development and implementation of the new information system, before
giving consideration to any lease financing that may be available, will be up to
$20 million annually through fiscal year 2000, plus maintenance and upkeep costs
which are not expected to be material. Similar Year 2000 readiness programs are
in place in the Company's United Kingdom and Catalog operational segments, and
the costs to address those segment's Year 2000 issues are not expected to be
material.

      There can be no assurance that the new North American information system
can be implemented on a timely basis or that it will deliver the desired
operational benefits. Nor can there be assurance that the initiatives put in
place to address the Year 2000 issues will identify and remove all potential
operational impacts. While significant economic detriment from Year


                                       14
<PAGE>   15
2000 issues is not expected, there can be no assurance that there will not be
operational difficulties in the Company's stores, warehouses, or corporate
offices, the financial magnitude of which is not currently estimable. The Year
2000 initiatives being conducted by the Company are expected to significantly
reduce the Company's level of uncertainty about the Year 2000 problem, including
the Year 2000 compliance and readiness of external partners. The Company
believes that, with the implementation of new North American business systems
and the completion of its Year 2000 initiatives as scheduled, the possibility of
significant interruptions of normal operations will be reduced. Although the
Company believes contingency plans will not need to be utilized based on
progress to date, contingency plans have been developed for each critical
system. The specifics of the contingency plans vary depending on the system and
assessed risk of non-compliance and such plans are modified periodically based
on review and testing. The plans are comprised of activities such as upgrading
existing systems, reallocating internal resources, obtaining additional external
resources, and implementing temporary manual processes.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISKS

     The Company is subject to the risk of fluctuating interest rates in the
ordinary course of business on certain assets including cash and cash
equivalents, and on borrowings under its revolving credit arrangement. The
Company has entered into interest rate swaps to lower its funding costs and
reduce its exposure to changes in short-term interest rates. Under these
arrangements, the Company may convert variable rate lease payments and
borrowings into borrowings at a fixed rate of approximately 6.6%. The Company
does not expect changes in fair value of the arrangements to have a significant
effect on the Company's operations, cash flow or financial position.

PART II.  OTHER INFORMATION

ITEM 1.  LEGAL PROCEEDINGS

      In January 1998, five substantially identical securities class action
lawsuits were filed against the Company in federal court in Phoenix, Arizona.
The cases allege that the Company and several of its officers and directors made
misleading statements about the Company's financial condition and earnings
prospects. The court considered the cases and plaintiffs filed a consolidated
amended complaint in March 1998. On June 3, 1999, the court granted the
Company's motion to dismiss the consolidated amended complaint. The court's
decision gives plaintiffs 60 days to file an amended complaint. The Company
believes plaintiffs' allegations are without merit and will continue to defend
itself vigorously.

      In addition, a former Pet City affiliate has retained counsel in the
United States and made allegations claiming that the Company misled the
shareholders of Pet City at the time of the acquisition of Pet City concerning
PETsMART's business, finances and prospects. On September 30, 1997, shortly
after the receipt of the allegations by PETsMART, Richard Northcott, the former
Chairman of Pet City, resigned as a director of the Company. No litigation has
been filed with respect to this matter, and the Company believes that the
allegations are without merit. Nevertheless, there can be no assurance that one
or more former Pet City affiliates will not initiate litigation seeking monetary
damages or an equitable remedy.

      On March 28, 1998, a lawsuit was filed in Federal District Court in the
Middle District of Florida entitled Cavucci et al v. PETsMART, Inc. (Case No.
98-CV-340). This class-action complaint alleges unspecified damages based on
various alleged violations of the Fair Labor Standards Act, including alleged
failures to pay overtime premiums. On May 12, 1998, the Company answered the
complaint denying all material allegations. The Court entered an order of
procedure and schedule for trial on July 20, 1998 which outlines all discovery
and trial dates. On November 30, 1998, PETsMART filed motions for partial
summary judgment on plaintiff's claim that in-store management positions were
misclassified as exempt under the Fair Labor Standards Act. These motions have
been denied. To date, there have been no settlement discussions and discovery is
ongoing.

      On November 20, 1998, a civil lawsuit was filed by a competitor in the
Ontario (Canada) General Court, entitled Pet Valu, Inc., et al v. PETsMART, Inc.
(Case No. 98 CV-159004). This case seeks purported monetary damages of
approximately US$63 million and claims that this amount is subject to trebling,
alleging that the Company engaged in unfair competitive practices in the Ontario
retail pet supply business. The complaint also claims that the Company
interfered with an alleged contract between the plaintiff and one of its
vendors. The Company has filed a formal response denying the allegations. The
Company believes that the allegations in the lawsuit are without merit and
intends to defend itself vigorously.

irrevocable telephonic notice followed immediately by written notice (provided,
however, that the Company's failure to confirm any telephonic notice in writing
shall not invalidate any notice so given), of its intention to borrow or
reborrow a Base Rate Advance hereunder. Notice shall be given to the
Administrative Lender prior to 1:00 p.m. Dallas, Texas time, in order for such
Business Day to count toward the minimum number of Business Days required. Such
notice of borrowing shall specify the requested funding date, which shall be a
Business Day, and the amount of the proposed aggregate Base Rate Advances to be
made by Lenders.

         (b) In the case of LIBOR Advances, the Company shall give the
Administrative Lender at least three Business Days' irrevocable written notice,
or irrevocable telephonic notice followed immediately by written notice
(provided, however, that the Company's failure to confirm any telephonic notice
in writing shall not invalidate any notice so given), of its intention to borrow
or reborrow a LIBOR Advance hereunder. Notice shall be given to the
Administrative Lender prior to 1:00 p.m., Dallas, Texas time, in order for such
Business Day to count toward the minimum number of Business Days required. LIBOR
Advances shall in all cases be subject to availability and to Article IX hereof.
For LIBOR Advances, the notice of borrowing shall specify the requested funding
date, which shall be a Business Day, the amount of the proposed aggregate LIBOR
Advances to be made by Lenders and the Interest Period selected by the Company,
provided that no such Interest Period shall extend past the Maturity Date, or
prohibit or impair the Company's ability to comply with Section 2.5 hereof.

         (c) Subject to Sections 2.1 and 2.9 hereof, at least three Business
Days prior to each Payment Date for a LIBOR Advance, the Company shall give the
Administrative Lender irrevocable written notice, or irrevocable telephonic
notice followed immediately by written notice (provided, however, that the
Company's failure to confirm any telephonic notice in writing shall not
invalidate any notice so given), specifying whether all or a portion of such
LIBOR Advance outstanding on the Payment Date (i) is to be repaid and then
reborrowed in whole or in part as a LIBOR Advance, (ii) is to be repaid and then
reborrowed in whole or in part as a Base Rate Advance, or (iii) is to be repaid
and not reborrowed; provided, however, notwithstanding anything in this
Agreement to the contrary, if on any Payment Date a Default shall exist, such
LIBOR Advance may only be reborrowed as a Base Rate Advance. Upon such Payment
Date, such LIBOR Advance shall, subject to the provisions hereof, be so repaid
and, as applicable, reborrowed.

                                      -16-
<PAGE>   22
         (d) The aggregate amount of Base Rate Advances to be made by the
Lenders on any day shall be in a principal amount which is at least $500,000 and
which is an integral multiple of $100,000; provided, however, that such amount
may equal the unused amount of the Commitment. The aggregate amount of LIBOR
Advances having the same Interest Period and to be made by the Lenders on any
day shall be in a principal amount which is at least $1,000,000 and which is an
integral multiple of $100,000.

         (e) The Administrative Lender shall promptly notify the Lenders of each
notice received from the Company pursuant to this Section. Failure of the
Company to give any notice in accordance with Sections 2.2(c) hereof shall
result in a repayment of any such existing Advance on the applicable Payment
Date by a Refinancing Advance which is a Base Rate Advance. Each Lender shall,
not later than 1:00 p.m., Dallas, Texas time, on the date of any Advance that is
not a Refinancing Advance, deliver to the Administrative Lender, at its address
set forth herein, such Lender's Specified Percentage of such Advance in
immediately available funds in accordance with the Administrative Lender's
instructions. On the date of any Advance hereunder, the Administrative Lender
shall, subject to satisfaction of the conditions set forth in Article IV,
promptly disburse the amounts made available to the Administrative Lender by the
Lenders by (i) transferring such amounts by wire transfer pursuant to the
Company's instructions, or (ii) in the absence of such instructions, crediting
such amounts to the account of the Company maintained with the Administrative
Lender. All Advances shall be made by each Lender according to its Specified
Percentage.

         (f) Unless a Lender shall have notified the Administrative Lender prior
to the date of any Advance that it will not make available its Specified
Percentage of the Advance, the Administrative Lender may assume that such Lender
has made the appropriate amount available in accordance with subsection (a)
above, and the Administrative Lender may, in reliance upon such assumption, make
available to the Company a corresponding amount. If and to the extent any Lender
shall not have made such amount available to the Administrative Lender, the
Lender and Company severally agree to repay to the Administrative Lender
forthwith on demand such corresponding amount together with interest thereon,
from the date such amount is made available to the Company until the date such
amount is repaid to the Administrative Lender, at (i) in the case of the
Company, the Base Rate, and (ii) in the case of such Lender, the Federal Funds
Rate.

         (g) The failure by any Lender to make available its Specified
Percentage of an Advance hereunder shall not relieve any other Lender of its
obligation, if any, to make available its Specified Percentage of any Advance.
In no event, however, shall any Lender be responsible for the failure of any
other Lender to make available any portion of an Advance.

         Section 2.3. Fees.

         (a) Commitment Fee. Subject to Section 10.9 hereof, the Company agrees
to pay to the Administrative Lender, for the ratable account of the Lenders, a
commitment fee (which shall be payable quarterly in arrears on each Quarterly
Date and on the Maturity Date) based on the daily average unused portion of the
Commitment (subject to Section 10.9 hereof, computed on the basis of a 360-day
year for the actual number of days elapsed) at the following per annum
percentages, applicable in the following situations:

               equal to or greater than 1.75 to 1

(C)      If the Fixed Charges Coverage Ratio is less than 1.75 to 1 but is              0.375%
               equal to or greater than 1.50 to 1

(D)      If the Fixed Charges Coverage Ratio is less than 1.50 to 1 but is              0.500%
               equal to or greater than 1.25 to 1

(E)      If the Fixed Charges Coverage Ratio is less than 1.25 to 1                     0.500%
</TABLE>

For purposes of calculation of the commitment fee, Letters of Credit outstanding
from time to time will reduce the unused portion of the Commitment. The
commitment fee shall be subject to reduction or increase, as applicable and as
set forth above, on a quarterly basis according to the performance of the
Company as tested by the Fixed Charges Coverage Ratio. Any such increase or
decrease in such fee shall be effective on the fifth day following the date of
receipt by the Administrative Lender of the financial statements required
pursuant to Section 6.14(a) or 6.14(b) hereof, as appropriate. If such financial
statements are not received by the fifth day following the date required, the
commitment fee shall be determined as if the Fixed Charges Coverage Ratio is
less than 1.25 to 1 until such time as such financial statements are received.
From and including the date hereof to the date of the initial adjustment of the
commitment fee to be made as provided above, the percentage shall be 0.500%.

         (b) The Company agrees to pay to the Administrative Lender for its
account and for the ratable account of the Lenders, the fees provided for in the
letter agreement dated as of the Agreement Date, between the Company and the
Administrative Lender on the date and in the amounts specified therein.

         (c) The Company agrees to pay to the Administrative Lender, for the
ratable account of the Lenders, a letter of credit fee on the average daily
amount for drawing under all outstanding Trade Letters of Credit, from the date
of issuance of the initial Trade Letter of Credit through the date of
termination of the final Trade Letter of Credit, at the rate of 0.625% per
annum, payable in arrears on each Quarterly Date and on the later of the
Maturity Date or the date of termination of the final Trade Letter of Credit.

         (d) The Company agrees to pay to the Administrative Lender, for the
ratable account of the Lenders, a per annum letter of credit fee on the average
daily amount for drawing under all outstanding Standby Letters of Credit, from
the date of issuance of the initial Standby Letter of Credit through the date of
termination of the final Standby Letter of Credit, at a rate equal to the then
applicable LIBOR Margin in effect from time to time, payable in arrears on each
Quarterly Date and on the later of the Maturity Date or the date of termination
of the final Standby Letter of Credit.

<PAGE>   24
         (e) The Company agrees to pay to the Administrative Lender, for the
sole account of the Issuing Bank, an issuance fee (which shall be payable
quarterly in arrears on each Quarterly Date and on the Maturity Date) equal to
0.125% per annum of the average daily amount available for drawing under all
outstanding Letters of Credit.

         Section 2.4. Reduction of Commitment.

         (a) The Company shall have the right from time to time, upon notice to
the Administrative Lender not later than 1:00 p.m. (Dallas time), three Business
Days in advance, to reduce the Commitment (and the Letter of Credit Commitment,
if applicable), in whole or in part; provided, however, that (i) the Company
shall pay the accrued commitment fee on the amount of such reduction, (ii) any
partial reduction (A) that results in a repayment of Base Rate Advances shall be
in an aggregate amount which is at least $500,000 and which is an integral
multiple of $100,000 and (B) that results in a repayment of LIBOR Advances shall
be in an aggregate amount which is at least $1,000,000 and which is in an
integral multiple of $100,000 and (iii) no voluntary reduction in the Commitment
shall cause any LIBOR Advance to be repaid prior to the last day of its Interest
Period.

         (b) Upon any reduction of the Commitment pursuant to this Section, the
Company shall immediately make a repayment of Advances in accordance with
Section 2.5 hereof. The 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 2.9 hereof, to the extent applicable. The
Company shall not have any right to rescind any termination or reduction. Once
reduced or terminated, the Commitment may not be increased or reinstated.

         (c) On the Maturity Date, the Commitment shall automatically reduce to
zero.

         Section 2.5. Prepayment and Repayment of Advances.

         (a) The principal amount of any Base Rate Advance may be prepaid in
full or in part at any time, without penalty, upon telephonic notice (to be
promptly followed by written notice) to the Administrative Lender not later than
11:00 a.m., Dallas, Texas time on the date of prepayment. LIBOR Advances may be
voluntarily prepaid upon three Business Days' prior telephonic notice (to be
promptly followed by written notice) to the Administrative Lender, but only so
long as the Company concurrently reimburses the Lenders in accordance with
Section 2.9 hereof. Any notice of prepayment shall be irrevocable.

         (b) On or before the date of any reduction of the Commitment, the
Company shall prepay outstanding Advances in an amount necessary to reduce the
sum of outstanding Advances and Reimbursement Obligations to an amount not
greater than the Commitment as so reduced pursuant to Section 2.4 hereof. The
Company shall first prepay all Base Rate Advances and shall thereafter prepay
LIBOR Advances. To the extent that any prepayment requires that a LIBOR Advance
be repaid on a date other than the last day of its Interest Period, the Company
shall reimburse each Lender in accordance with Section 2.9 hereof.

         (c) Any prepayment of a LIBOR Advance shall be (i) in an aggregate
amount of at least $1,000,000 and which is an integral multiple of $100,000 and
(ii) accompanied by (A) interest

                                      -19-
<PAGE>   25
accrued on the principal amount being prepaid and (B) amounts due in accordance
with Section 2.9 hereof. Any voluntary partial prepayment of a Base Rate Advance
shall be in a principal amount of $100,000 or an integral multiple thereof.

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

         (e) The principal amount of each LIBOR Advance hereunder shall be due
and payable on its Payment Date, which principal payment may be made by means of
a Refinancing Advance.

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

         (g) All telephonic notices under Article III hereof shall be made to
NationsBank, N.A., Attn: Traci Kuketz, 901 Main Street, 14th Floor, Dallas,
Texas 75202, (214) 209-3970, or such other person as the Administrative Lender
may from time to time specify.

         Section 2.6. Interest on Advances.

         (a) Subject to Section 10.9 hereof, Base Rate Advances shall bear
interest at the lesser of (a) the Highest Lawful Rate and (b) the Base Rate as
in effect from time to time. Accrued interest on each Base Rate Advance shall be
computed on the basis of a year of 365 or 366 days, as applicable, for the
number of days actually elapsed, and shall be due and payable in arrears on each
Monthly Date. If the amount of interest payable for the account of any Lender on
any interest payment date in respect of any Base Rate Advance would exceed the
Maximum Amount, the amount of interest payable on such interest payment date
shall be automatically reduced to the Maximum Amount. If the amount of interest
payable for the account of any Lender in respect of any interest computation
period is reduced pursuant to the immediately preceding sentence and the amount
of interest payable for its account in respect of any subsequent interest
computation period would be less than the Maximum Amount, then the amount of
interest payable for its account in respect of such subsequent interest
computation period shall be automatically increased to such Maximum Amount;
provided that at no time shall the aggregate amount by which interest paid for
the account of any Lender has been increased pursuant to this sentence exceed
the aggregate amount by which interest paid for its account has theretofore been
reduced pursuant to the immediately preceding sentence.

         (b) Subject to Section 10.9 hereof, each LIBOR Advance shall bear
interest at a rate per annum equal to the LIBOR Basis for such Advance. The
Administrative Lender, whose determination shall be conclusive, shall determine
the LIBOR Basis on the second Business Day prior to the applicable funding date
and shall notify the Company and the Lenders of such LIBOR Basis. Interest on
each LIBOR Advance shall be computed on the basis of a 360-day year for the
actual number of days elapsed, and shall be payable in arrears on the applicable
Payment Date and on the Maturity Date; provided, however, that if the Interest
Period for such Advance exceeds three months, interest shall also be due and
payable in arrears on each Quarterly Date during such Interest Period.

                                      -20-
<PAGE>   26
         (c) If the Company fails to give the Administrative Lender timely
notice of its selection of a LIBOR Basis or an Interest Period for a LIBOR
Advance, or if for any reason a determination of a LIBOR Basis for any Advance
is not timely concluded due to the fault of the Company, the Base Rate shall
apply to the applicable Advance.

         (d) All past due principal and interest shall, upon notice by the
Administrative Lender to the Company, bear interest at the lesser of (i) the
Base Rate as in effect from time to time, plus 3% or (ii) the Highest Lawful
Rate, and shall be due and payable on demand.

         Section 2.7. Computations and Manner of Payments.

         (a) The Company shall make each payment hereunder and under the other
Loan Papers not later than 1:00 p.m. (Dallas time) on the day when due in same
day funds to the Administrative Lender, for the ratable account of the Lenders
unless otherwise specifically provided herein, at the Administrative Lender's
office at 901 Main Street, Dallas, Texas 75202, for credit to commercial loan
FTA #0180019828, reference: PETsMART, Inc. No later than the end of each day
when each payment hereunder is made, the Company shall notify Traci Kuketz, or
such other person as the Administrative Lender may from time to time specify.

         (b) Unless the Administrative Lender shall have received notice from
the Company prior to the date on which any payment is due hereunder that the
Company will not make payment in full, the Administrative Lender may assume that
such payment is so made on such date and may, in reliance upon such assumption,
make distributions to the Lenders. If and to the extent the Company shall not
have made such payment in full, each Lender shall repay to the Administrative
Lender forthwith on demand the applicable amount distributed, together with
interest thereon at the Federal Funds Rate, from the date of distribution until
the date of repayment. The Company hereby authorizes each Lender, if and to the
extent payment is not made when due hereunder, to charge the amount so due
against any account of the Company with such Lender.

         (c) Subject to Section 10.9 hereof, all computations of fees hereunder
shall be made on the basis of a year of 360 days, for the actual number of days
(including the first day but excluding the last day) occurring in the period for
which such fee is payable. All payments under the Loan Papers shall be made in
United States dollars, and without setoff, counterclaim, or other defense.

         (d) Whenever any payment to be made hereunder or under any other Loan
Papers shall be stated to be due on a day other than a Business Day, such
payment shall be made on the next succeeding 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 be included in the
computation of interest or fees, if applicable.

         Section 2.8. Yield Protection.

         (a) If any Lender determines that compliance with any Applicable Law
(including without limitation existing and future Applicable Laws), or any
guideline or request from any central bank or other Tribunal (whether or not
having the force of Applicable Law) affects or would affect the amount of
capital required or expected to be maintained by such Lender or any of its
Affiliates, and

                                      -21-
<PAGE>   27
that the amount of such capital is increased by or based upon the existence of
any Commitment, Advance, or Letter of Credit (or similar commitments, loans or
letters of credit), then, upon demand by such Lender, the Company shall
immediately pay to such Lender, from time to time as specified, additional
amounts sufficient to compensate it or any of its Affiliates for the reduction
in rate of return on such Lender's or Affiliate's capital below that which such
Lender or Affiliate could have achieved but for such compliance, guideline or
request, to the extent that such Lender or Affiliate reasonably determines such
increase in capital to be allocable to the existence or maintenance of or any
participation in any Commitment, Advance, or Letter of Credit.

         (b) Provided that notice shall have been given to the Company of the
reasons therefor and in reasonable detail, determinations by any Lender for
purposes of this Section shall be conclusive, absent manifest error.

         Section 2.9. Reimbursement. Whenever any Lender shall sustain or incur
any losses or reasonable out-of-pocket expenses in connection with (a) failure
by the Company to borrow any LIBOR Advance after having given notice of its
intention to borrow in accordance with Section 2.2 hereof (whether by reason of
the Company's election not to proceed or the non-fulfillment of any of the
conditions set forth in Article IV hereof), (b) failure by the Company to prepay
any LIBOR Advance after having given notice of its intention to prepay in
accordance with Section 2.6 hereof, or (c) any prepayment for any reason of any
LIBOR Advance in whole or in part (including a prepayment pursuant to Sections
2.6, 7.2 and 9.3(b) hereof), the Company agrees to pay to any such Lender, upon
its demand, an amount sufficient to compensate such Lender for all such losses,
costs and out-of-pocket expenses, subject to Section 10.9 hereof. Such Lender's
good faith determination of the amount of such losses, costs or out-of-pocket
expenses, calculated in its usual fashion, absent manifest error, shall be
binding and conclusive. Such losses shall include, without limiting the
generality of the foregoing, lost profits and reasonable expenses incurred by
such Lender in connection with the re-employment of funds prepaid, repaid,
converted or not borrowed, converted or paid, as the case may be. Upon request
of the Company, such Lender shall provide a certificate setting forth the amount
to be paid to it by the Company hereunder and calculations therefor.

         Section 2.10. LIBOR Lending Offices. Each Lender's initial LIBOR
Lending Office is set forth opposite its name on the signature pages hereto.
Each Lender shall have the right at any time and from time to time to designate
a different office of itself or of any Affiliate as such Lender's LIBOR Lending
Office, and to transfer any outstanding LIBOR Advance to such LIBOR Lending
Office. No such designation or transfer shall result in any liability on the
part of the 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 9.2 or 9.3 hereof, 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.

         Section 2.11. Calculation of LIBOR Rate. The provisions of this
Agreement relating to calculation of the LIBOR 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 as it sees fit.

                                   ARTICLE III

                                LETTERS OF CREDIT

         Section 3.1. Letter of Credit Commitment; Reimbursement.

         (a) Subject to the terms and conditions hereof, and in reliance upon
subsection (b) below, the Issuing Bank agrees, from time to time until the
Maturity Date, to issue one or more Letters of Credit for the account of the
Company. The aggregate amount of outstanding Letters of Credit shall not exceed
at any time outstanding, the lesser of (i) the Letter of Credit Commitment and
(ii) an amount equal to the sum of the Commitment minus the aggregate
Reimbursement Obligations and Advances then outstanding. Letters of Credit may
be issued for activities and payments relating to the ordinary course of
business of the Company and its Subsidiaries. No Letter of Credit shall be
issued if issuance, in the Administrative Lender's or the Issuing Bank's sole
judgment, would violate any Applicable Law or any internal policy or standard of
the Issuing Bank.

         (b) No Letter of Credit shall have an expiration date (including all
rights of renewal) later than the earlier of (i) the Maturity Date or (ii) the
date which is eighteen months after the issuance thereof. The Company shall be
liable for the repayment of any Reimbursement Obligations. If on the Maturity
Date there are any Letters of Credit outstanding, the Company shall deposit with
the Administrative Lender on the Maturity Date Cash Collateral in an amount not
less than the maximum amount then available to be drawn under such outstanding
Letters of Credit.

         (c) Promptly upon issuance of a Letter of Credit, the Issuing Bank
shall notify the Administrative Lender and each Lender of the date of issuance,
amount, and expiration date of such Letter of Credit, and shall deliver a copy
to any Lender upon request. Upon issuance, each Lender shall thereupon have
purchased and received from the Issuing Bank a participation in such Letter of
Credit and the Company's reimbursement obligations relating thereto under the
applicable letter of credit application and agreement, to the extent of such
Lender's Specified Percentage of the maximum amount available to be drawn under
such Letter of Credit (assuming compliance with all conditions to drawing).

         (d) The payment by the Issuing Bank of a draft drawn under any Letter
of Credit shall constitute for all purposes of this Agreement the making by the
Issuing Bank of an 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 4 hereof). In the event that a payment under any
Letter of Credit is not reimbursed by the Company by 11:00 a.m. (Dallas time) on
the first Business Day after notice of such drawing has been given by the
Issuing Bank to the Company, the Issuing Bank shall promptly notify
Administrative Lender and each other Lender. Each such Lender shall, on the
first Business Day following such notification, make an Advance, which shall
bear interest at the Base Rate, and shall be used to repay the applicable
portion of the Issuing Bank's Advance with respect to such Letter of Credit, in
an amount equal to the amount of its Specified Percentage in such drawing for
application to reimburse the Issuing Bank (but without any requirement for
compliance with the applicable conditions set forth in Article 4 hereof) and
shall make available to the Administrative Lender for the account of the Issuing
Bank, by deposit at the Administrative Lender's

                                      -23-
<PAGE>   29
office, in same day funds, the amount of such Advance. In the event that any
Lender fails to make available to the Administrative Lender for the account of
the Issuing Bank the amount of such Advance on the date specified in the notice
from the Issuing Bank to such Lender, the Issuing Bank shall be entitled to
recover such amount on demand from such Lender together with interest thereon
from such date until paid at a rate per annum equal to the lesser of (i) the
Highest Lawful Rate or (ii) the Federal Funds Rate.

         Section 3.2. Standard of Care.

         (a) The Issuing Bank agrees that it shall give the same care and
attention to each Letter of Credit as it gives to its other letters of credit.
The Lenders and the Company agree that, in paying any draw under any Letter of
Credit, the Issuing Bank shall not have any responsibility to obtain any
document (other than any sight draft or other document required by the Letter of
Credit), or to ascertain or inquire as to the validity or accuracy of any
document or the authority of the Person delivering any document.

         (b) None of the Issuing Bank and its representatives, directors,
officers, employees, or agents shall be liable to any Lender, the Company, or
any other Person for (i) any action taken or omitted in connection with this
Article or any Letters of Credit at the request or with the approval of Majority
Lenders, (ii) any action taken or omitted in the absence of gross negligence and
willful misconduct, (iii) any recitals, statements, representations, or
warranties contained in any document distributed to any Lender, (iv) the
creditworthiness of the Company or any of its Subsidiaries, (v) the execution,
effectiveness, genuineness, validity, or enforceability of any Loan Papers, (vi)
the value, sufficiency, perfection, or priority of any security for any
obligations under the Loan Papers, or (vii) any circumstances beyond the control
of the Issuing Bank with respect to any Letter of Credit. The Issuing Bank shall
not incur any liability by acting in reasonable reliance upon any advice of

Administrative Lender, and Lenders, upon demand, for any Taxes, (other than
Taxes on the overall net income of the Administrative Lender, the Issuing Bank
or any Lender), fees, charges, or other costs or expenses whatsoever, including

The Company agrees with the Administrative Lender, Issuing Bank, and Lenders
that they shall not be responsible for, and the Company's obligations shall not
be affected by, any matter or event whatsoever pertaining to any Letter of
Credit, including without limitation the validity or genuineness of documents or

their representatives, directors, officers, employees, and agents from and
against all liabilities, obligations, losses, damages, penalties, actions,
judgments, suits, costs, expenses, and/or disbursements of any kind or nature
whatsoever that may be imposed on, asserted against, or incurred by the Issuing
Bank or any Lender in any way with respect to any Letter of Credit issued for
the account of the Company, or any action taken or omitted by the Issuing Bank
with respect to any such Letter of Credit, including any negligence of the
Issuing Bank; provided, however, that the Issuing Bank shall not be so
indemnified and held harmless for, and shall be liable to the Company only to
the extent of, any direct (as opposed to consequential) damages suffered by the
Company which the Company proves were caused by the Issuing Bank's willful
misconduct or gross negligence. The Issuing Bank shall not be liable for error,
omission, interruption, or delay in transmission, dispatch, or delivery of any
message or advice, however transmitted, in connection with any Letter of Credit.
The Company agrees that any action taken or omitted by the Issuing Bank, the
Administrative Lender, or any Lender with respect to any Letter of Credit or
related draws, drafts, or documents, if done in good faith and in accordance
with the standards of care specified in applicable state Laws or the Uniform
Customs and Practices for Documentary Credits as most recently published by the
International Chamber of Commerce (which publication shall control in the event
of any conflict between such publication and any such Applicable Law) shall be
binding on the Company and shall not put the Issuing Bank, the Administrative
Lender, or any Lender under any liability to the Company.

                         REPRESENTATIONS AND WARRANTIES

         The Company represents and warrants that the following are true and
correct:

         Section 5.1. Organization and Qualification. Each of the Company and
its Subsidiaries is a corporation duly organized, validly existing, and in good
standing under the Applicable Laws of its state of organization. Each of the
Company and its Subsidiaries is qualified to do business in all jurisdictions
where the nature of its business or Properties require such qualification. Set
forth on Schedule I attached hereto is a complete and accurate listing of each
Subsidiary of the Company, showing (a) the jurisdiction of its organization and
its mailing address, which is the principal place of business and executive
offices of such Subsidiary unless otherwise indicated, (b) the classes of
capital stock, and the numbers of shares authorized and outstanding, and (c)
each owner of outstanding shares on the date hereof, indicating the ownership
percentage. All outstanding shares of capital stock of the Company and its
Subsidiaries are validly issued, fully paid, and nonassessable and, to the
extent owned by the Company or its Subsidiaries, are owned free and clear of all
Liens, including any restrictions on hypothecation or transfer.

         Section 5.2. Due Authorization; Validity. The Boards of Directors of
the Company and its Subsidiaries have duly authorized the execution, delivery,
and performance of the Loan Papers to be executed by each. No consent of the
stockholders of the Company and its Subsidiaries (except any consent already
obtained) is required as a prerequisite to the validity and enforceability of
any Loan Papers or any other document contemplated hereby. Each of the Company
and its Subsidiaries has full legal right, power, and authority to execute,
deliver, and perform under the Loan Papers to be executed and delivered by it.
The Loan Papers have been duly executed and delivered by the

                                      -28-
<PAGE>   34
Company and each Subsidiary and constitute the legal, valid, and binding
respective obligations of the Company and its Subsidiaries, enforceable in
accordance with their respective terms (subject as to enforcement of remedies to
any applicable bankruptcy, reorganization, moratorium, or similar Applicable
Laws or principles of equity affecting the enforcement of creditors' rights
generally).

         Section 5.3. Conflicting Agreements and Other Matters. The execution
and delivery of any Loan Papers, and performance thereunder, does not conflict
with, or result in a breach of the terms, conditions, or provisions of, or
constitute a default under, or result in any violation of, or result in the
creation of any Lien upon any Properties of the Company or its Subsidiaries
under, or require any consent (other than consents already obtained), approval,
or other action by, notice to, or filing with any Tribunal or Person pursuant
to, the articles of incorporation or bylaws of the Company or any of its
Subsidiaries, any award of any arbitrator, or any agreement, instrument, or
Applicable Law to which the Company, any Subsidiary, or any of their Properties
is subject.

         Section 5.4. Financial Statements. The financial statements of the
Company and its Subsidiaries delivered to the Administrative Lender and Lenders
fairly present their financial condition and the results of operations as of the
dates and for the periods shown, all in accordance with GAAP. The latest of such
financial statements reflects all material liabilities, direct and contingent,
of the Company and its Subsidiaries that are required to be disclosed in
accordance with GAAP. As of the date of the latest of such financial statements,
there were no Contingent Liabilities, liabilities for Taxes, forward or
long-term commitments, or unrealized or anticipated losses from any unfavorable
commitments that are substantial in amount and that are not reflected on such
financial statements or otherwise disclosed in writing to the Administrative
Lender. Since January 31, 1999, there has been no Material Adverse Change. The
Company and each of its Subsidiaries is Solvent.

         Section 5.5. Litigation. Shown on Schedule III attached hereto is all
Litigation that is pending or, to the best of the Company's knowledge,
threatened against the Company or its Subsidiaries on the date hereof, and that
involves a claim for damages or reasonably expected potential liability of
$500,000 or more. There is no pending or, to the best of the Company's
knowledge, threatened Litigation against the Company or its Subsidiaries that
could constitute a Material Adverse Change.

         Section 5.6. Compliance With Applicable Laws Regulating the Incurrence
of Indebtedness. No proceeds of any Advance will be used directly or indirectly
to acquire any security in any transaction which is subject to Sections 12, 13
and 14 of the Securities Exchange Act of 1934, as amended. The Company and its
Subsidiaries are not engaged in the business of extending credit for the purpose
of purchasing or carrying margin stock (within the meaning of Regulation U
issued by the Board of Governors of the Federal Reserve System), and no proceeds
of any Advance will be used to purchase or carry any margin stock or to extend
credit to others for the purpose of purchasing or carrying any margin stock.
Following the Company's intended use of the proceeds of each Advance, not more
than 25% of the value of the assets of the Company, both individually and on a
consolidated basis with its Subsidiaries, will be "margin stock" within the
meaning of Regulation U. The Company and its Subsidiaries are not subject to
regulation under the Public Utility Holding Company Act of 1935, the Federal
Power Act, the Investment Company Act of 1940, the Interstate Commerce Act (as
any of the preceding acts have been amended), or any other Applicable Law that
the incurring of Indebtedness by the Company or its Subsidiaries would violate
in any material

                                      -29-
<PAGE>   35
respect, including without limitation Applicable Laws relating to common or
contract carriers or the sale of electricity, gas, steam, water, or other public
utility services.

         Section 5.7. Licenses, Title to Properties, and Related Matters. The
Company and its Subsidiaries possess all material Licenses and are not in
violation thereof in any material respect. The Company and each of its
Subsidiaries has full power, authority, and legal right to own and operate its
Properties, and to conduct its business. Each has good and indefeasible title
(fee or leasehold, as applicable) to its Properties, subject to no Lien of any
kind, except as permitted hereunder. None of the Company and its Subsidiaries is
in violation of its respective articles of incorporation or bylaws (other than
immaterial violations of the bylaws of such Subsidiaries), or any Applicable
Law, or material agreement or instrument binding on or affecting it or any of
its Properties. No business or Properties of the Company and its Subsidiaries is
affected by any strike, lock-out, or other labor dispute, drought, storm,
earthquake, embargo, act of God or public enemy, or other casualty that could
constitute a Material Adverse Change.

         Section 5.8. Outstanding Indebtedness. The Company and its Subsidiaries
have no outstanding Indebtedness, Contingent Liabilities, or Liens, except as
shown on Schedule II attached hereto.

         Section 5.9. Taxes. The Company and its Subsidiaries have filed all
federal, state, and other Tax returns (or extensions related thereto) which are
required to be filed, and have paid all Taxes as shown on said returns, as well
as all other Taxes, to the extent due and payable. All Tax liabilities of the
Company and its Subsidiaries are adequately provided for on their books,
including interest and penalties, and adequate reserves have been established
therefor in accordance with GAAP. No income Tax liability of a material nature
has been asserted by taxing authorities for Taxes in excess of those already
paid, and no taxing authority has notified the Company or any of its
Subsidiaries of any material deficiency in any Tax return.

         Section 5.10. ERISA. Each Plan has satisfied the minimum funding
standards under all Applicable Laws applicable thereto, and no Plan has an
accumulated funding deficiency thereunder. The Company and its Subsidiaries have
not incurred any material liability to the PBGC with respect to any Plan. No
ERISA Event has occurred with respect to any Plan. The Company has not
participated in any Prohibited Transaction with respect to any Plan or trust
created thereunder, and the consummation of the transactions contemplated hereby
will not involve any Prohibited Transaction. None of the Company, its
Subsidiaries, or any ERISA Affiliate has incurred any Withdrawal Liability to
any Multiemployer Plan. None of the Company, its Subsidiaries, or any ERISA
Affiliate has been notified by the sponsor of a Multiemployer Plan that such
Multiemployer Plan is in reorganization or has been terminated, within the
meaning of Title IV of ERISA.

         Section 5.11. Environmental Laws. Except as set forth on Schedule V
hereto, the real Properties (whether leased or owned) of the Company or any of
its Subsidiaries, and the operations conducted thereon by any of them or, to the
best of the Company's knowledge, any current or prior owner or operator thereof,
(a) do not violate and have not violated any applicable Environmental Law, the
violation of which would constitute a Material Adverse Change or result in
penalties, fines, or damages in an aggregate amount of $100,000 or more, and (b)
are not subject to any pending or threatened investigation or proceeding by any
Tribunal or to any remedial obligations under any

                                      -30-
<PAGE>   36
Environmental Law. All Licenses have been obtained or filed that are required
under any Environmental Law in connection with the use of such Property and
assets (including without limitation past or present treatment, storage,
disposal, or release of any Hazardous Materials into the environment), except
where the failure to obtain any such License would not constitute a Material
Adverse Change. No Hazardous Materials are generated or produced at or in
connection with the Properties and operations of the Company and its
Subsidiaries, except in compliance with Environmental Laws. The Company and its
Subsidiaries have no material potential liability with respect to any release of
any Hazardous Materials into the environment. The use which the Company and its
Subsidiaries make or intend to make of the real Property (whether leased or
owned) on which any of their operations is conducted will not result in the
unlawful or unauthorized disposal or other release of any Hazardous Materials,
except in compliance with applicable Environmental Laws.

         Section 5.12. Disclosure. None of the Company and its Subsidiaries has
made a material misstatement of fact, or failed to disclose any fact necessary
to make the facts disclosed not misleading, to the Administrative Lender, any
Lender, or the Issuing Bank during the course of application for and negotiation
of any Loan Papers or otherwise in connection with any Advances or Letters of
Credit. There is no fact known to the Company that materially adversely affects
any of the Company's and its Subsidiaries' Properties or businesses, or that
would constitute a Material Adverse Change, and that has not been set forth in
the Loan Papers or in other documents furnished to the Administrative Lender,
Lenders, and Issuing Bank.

         Section 5.13. Year 2000. The Company has (i) initiated a review and
assessment of all areas within its and each of its Subsidiaries' business and
operations (and has made appropriate inquiry regarding those affected by
suppliers and vendors) that could be adversely affected by the "Year 2000
Problem" (that is, the risk that computer applications used by the Company or
any of its Subsidiaries (or its suppliers and vendors) may be unable to
recognize and perform properly date-sensitive functions involving certain dates
prior to and any date after December 31, 1999), (ii) developed a plan for
addressing the Year 2000 Problem on a timely basis, and (iii) to date, operated
in accordance with such plan. The Company reasonably believes that all computer
applications (including those of its suppliers and vendors) that are material to
its or any of its Subsidiaries' business and operations on January 1, 2000 will,
on a timely basis, be able to perform properly date-sensitive functions for all
dates before and after January 1, 2000 (that is, be "Year 2000 compliant"),
except to the extent that a failure to do so could not reasonably be expected to
cause a Material Adverse Change.

otherwise released on or prior to the Release Date), resulting from or in
connection with the ownership of the real property, regardless of whether the

Environmental Law at the time of its existence or occurrence, or whether the
act, omission, event or circumstance is caused by or relates to the negligence
of any indemnified Person; provided that, the Company shall not be under any
obligation to indemnify the Administrative Lender or any Lender to the extent
that any such liability arises as the result of the gross negligence or willful

provided for under Section 7.1 hereof), all of which are hereby expressly waived
(except to the extent waiver of the foregoing is not permitted by Applicable
Law);

         (b) Upon the occurrence of an Event of Default described in Section
7.1(f) hereof, the aggregate unpaid principal balance of and accrued interest on
all Advances shall automatically thereupon become due and payable concurrently
therewith and the Commitment shall automatically terminate, all without any
action by the Administrative Lender or any Lender, and without diligence,
presentment, demand, protest, notice of protest or intent to accelerate, or
notice of any other kind, all of which are hereby expressly waived;

         (c) The Administrative Lender may, and shall upon the request of the
Majority Lenders, demand payment of an amount equal to the maximum amount
available to be drawn under all Letters of Credit; demand presentation of draws
on the Letters of Credit by the beneficiaries thereof, to the extent permitted
thereunder; require the Company to deposit with the Administrative Lender cash
or Cash Equivalents in an amount equal to the maximum amount available to be
drawn under all Letters of Credit; and/or retain, as collateral for the
reimbursement obligations of the Company with respect thereto, any amounts
received upon foreclosure, or in lieu of foreclosure, through offset, as
proceeds of any collateral or otherwise; and

         (d) The Administrative Lender and the Lenders may exercise any Rights
afforded them under any Loan Papers, by Applicable Law, including but not
limited to the UCC, at equity, or otherwise.

         Section 7.3. Cumulative Rights. All Rights available to the
Administrative Lender, Lenders, and Issuing Bank under the Loan Papers shall be
cumulative of and in addition to all other Rights granted thereto at Applicable
Law or in equity, whether or not amounts owing thereunder shall be due and
payable, and whether or not the Administrative Lender, any Lender, or the
Issuing Bank shall have instituted any suit for collection or other action in
connection with the Loan Papers.

         Section 7.4. Waivers. The acceptance by the Administrative Lender, any
Lender, or the Issuing Bank at any time and from time to time of partial payment
of any amount owing under any Loan Papers shall not be deemed to be a waiver of
any Event of Default then existing. No waiver by the Administrative Lender, any
Lender, or the Issuing Bank of any Event of Default shall be deemed to be a
waiver of any Event of Default other than such Event of Default. No delay or
omission by the Administrative Lender, any Lender, or the Issuing Bank in
exercising any Right under the Loan Papers shall impair such Right or be
construed as a waiver thereof or an acquiescence therein, nor shall any single
or partial exercise of any such Right preclude other or further exercise
thereof, or the exercise of any other Right under the Loan Papers or otherwise.

         Section 7.5. Expenditures. The Company agrees to reimburse the
Administrative Lender, Lenders, and Issuing Bank for any sums spent by any of
them in connection with the exercise of any Right provided herein. Such sums
shall bear interest at the (i) lesser of the Base Rate in effect from time to
time, plus 3.0% or (ii) the Highest Lawful Rate, from the date spent until the
date of repayment by the Company.

         Section 7.6. Control. None of the covenants or other provisions
contained in this Agreement shall, or shall be deemed to, give the
Administrative Lender, Lenders, or Issuing Bank any Rights to exercise control
over the affairs and/or management of the Company or any of its Subsidiaries,
the power of the Administrative Lender, Lenders, and Issuing Bank being limited
to the Rights to exercise the remedies provided in this Article; provided,
however, that if the Administrative Lender, any Lender, or the Issuing Bank
becomes the owner of any stock or other equity interest in any Person, whether
through foreclosure or otherwise, it shall be entitled to exercise such legal
Rights as it may have by being an owner of such stock or other equity interest
in such Person.

                                  ARTICLE VIII

                            THE ADMINISTRATIVE LENDER

         Section 8.1. Authorization and Action. Each of the Lenders and Issuing
Bank hereby appoints and authorizes the Administrative Lender to take such
action as agent on its behalf and to exercise such powers under this Agreement
and the other Loan Papers as are delegated to the Administrative Lender by the
terms hereof, together with such powers as are reasonably incidental thereto. As
to any matters not expressly provided for by this Agreement and the other Loan
Papers (including without limitation enforcement or collection of the Notes),
the Administrative Lender shall not be required to exercise any discretion or
take any action, but shall be required to act or to refrain from acting (and
shall be fully protected in so acting or refraining from acting) upon the
instructions of the Majority Lenders (or all Lenders, if required under Section
9.1 hereof), and such instructions shall be binding upon all Lenders; provided,
however, that the Administrative Lender shall not be required to take any action
which exposes the Administrative Lender to personal liability or which is
contrary to any Loan Papers or Applicable Law. The Administrative Lender agrees
to give to each Lender prompt notice of each notice given to it by the Company
pursuant to the terms of this Agreement, and to distribute promptly to each
applicable Lender in like funds all amounts delivered to the Administrative
Lender by the Company for the ratable or individual account of any Lender. The
Administrative Lender shall have no trustee or other fiduciary relationship in
respect of any Lender by reason of this Agreement or any other Loan Paper. The
duties of the Administrative Lender under this Agreement and the other Loan
Papers are mechanical and administrative in nature.

         Section 8.2. Administrative Lender's Reliance, Etc. Neither the
Administrative Lender, nor any of its directors, officers, agents, employees, or
representatives shall be liable for any action taken or omitted to be taken by
it or them under or in connection with this Agreement or any other Loan Papers,
except for its or their own gross negligence or willful misconduct. Without
limitation of the generality of the foregoing, the Administrative Lender (a) may
treat the payee of any Note as the holder thereof until the Administrative
Lender receives written notice of the assignment or transfer thereof signed by
such payee and in form satisfactory to the Administrative Lender; (b) may
consult with legal counsel (including counsel for the Company or any of its
Subsidiaries), independent public accountants, and other experts selected by it,
and shall not be liable for any action taken or omitted to be taken in good
faith by it in accordance with the advice of such counsel, accountants, or
experts; (c) makes no warranty or representation to any Lender and shall not be
responsible to any Lender for any statements, warranties, or representations
made in or in connection with this Agreement or any other Loan Papers; (d) shall
not have any duty to ascertain or to inquire as to the performance or

                                      -43-
<PAGE>   49
observance of any of the terms, covenants, or conditions of this Agreement or
any other Loan Papers on the part of the Company or its Subsidiaries or to
inspect the Property (including the books and records) of the Company or its
Subsidiaries; (e) shall not be responsible to any Lender for the due execution,
legality, validity, enforceability, genuineness, sufficiency, or value of this
Agreement, any other Loan Papers, or any other instrument or document furnished
pursuant hereto; and (f) shall incur no liability under or in respect of this
Agreement or any other Loan Papers by acting upon any notice, consent,
certificate, or other instrument or writing (which may be by telegram, cable,
telex, or telecopy) believed by it to be genuine and signed or sent by the
proper party or parties.

         Section 8.3. NationsBank, N.A. and Affiliates. With respect to its
Commitment, its Advances, and any Loan Papers, NationsBank, N.A. shall have the
same Rights under this Agreement as any other Lender and may exercise the same
as though it were not the Administrative Lender. NationsBank, N.A., and its
Affiliates may accept deposits from, lend money to, act as trustee under
indentures of, and generally engage in any kind of business with, the Company,
any Affiliate thereof, and any Person who may do business therewith, all as if
NationsBank, N.A. were not the Administrative Lender and without any duty to
account therefor to any Lender.

         Section 8.4. Lender Credit Decision. Each Lender acknowledges that it
has, independently and without reliance upon the Administrative Lender or any
other Lender, and based on the financial statements referred to in Sections 5.4
and 6.14 hereof 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 the Administrative Lender or any other Lender and based on such
documents and information as it shall deem appropriate at the time, continue to
make its own credit decisions in taking or not taking action under this
Agreement and the other Loan Papers.

         Section 8.5. Indemnification by Lenders. Lenders agree to indemnify the
Administrative Lender, pro rata according to their Specified Percentages from
and against any and all liabilities, obligations, losses, damages, penalties,
actions, judgments, suits, costs, expenses, or disbursements of any kind or
nature whatsoever which may be imposed on, incurred by, or asserted against the
Administrative Lender in any way relating to or arising out of any Loan Papers
or any action taken or omitted by the Administrative Lender thereunder,
including any negligence of the Administrative Lender; provided, however, that
no Lender shall be liable for any portion of such liabilities, obligations,
losses, damages, penalties, actions, judgments, suits, costs, expenses, or
disbursements resulting from the Administrative Lender's gross negligence or
willful misconduct. Without limitation of the foregoing, Lenders agree to
reimburse the Administrative Lender, pro rata according to their Specified
Percentages, promptly upon demand for any out-of-pocket expenses (including
attorneys' fees) incurred by the Administrative Lender in connection with the
preparation, execution, delivery, administration, modification, amendment, or
enforcement (whether through negotiation, legal proceedings or otherwise) of, or
legal advice in respect of rights or responsibilities under, the Loan Papers.

         Section 8.6. Successor Administrative Lender. The Administrative Lender
may resign at any time by giving written notice thereof to the Lenders and
Company, and may be removed at any time with or without cause by the action of
all Lenders (other than the Administrative Lender, if it is a Lender), or by the
Company upon thirty (30) days prior written notice from the Company to the

                                      -44-
<PAGE>   50
Administrative Lender if, at any time, the Administrative Lender's Specified
Percentage is less than eight percent (8.0%); provided, however, that if a
successor Administrative Lender is appointed without the consent of the Majority
Lenders pursuant to the third sentence of this Section, such successor
Administrative Lender may be removed by the Majority Lenders and Company. Upon
any such resignation or removal, the Majority Lenders shall have the right to
appoint a successor Administrative Lender, with the consent of the Company so
long as no Event of Default has occurred and is continuing (which shall not be
unreasonably withheld). If no successor Administrative Lender shall have been so
appointed and shall have accepted such appointment within 30 days after the
retiring Administrative Lender's giving of notice of resignation or the Lenders'
removal of the retiring Administrative Lender, then the retiring Administrative
Lender may, on behalf of the Lenders, appoint a successor Administrative Lender,
which shall be a commercial bank organized under the Applicable Laws of the
United States of America or of any State thereof and having a combined capital
and surplus of at least $50,000,000. Upon the acceptance of any appointment as
the Administrative Lender hereunder by a successor Administrative Lender, such
successor Administrative Lender shall thereupon succeed to and become vested
with all the Rights and duties of the retiring Administrative Lender, and the
retiring Administrative Lender shall be discharged from its duties and
obligations under the Loan Papers. Notwithstanding any Administrative Lender's
resignation or removal hereunder, the provisions of this Article shall continue
to inure to its benefit as to any actions taken or omitted to be taken by it
while it was the Administrative Lender under this Agreement.

                                   ARTICLE IX

                            Changes in Circumstances

         Section 9.1. LIBOR Basis Determination Inadequate. If with respect to
any proposed LIBOR Advance for any Interest Period, any Lender determines that
(i) deposits in dollars (in the applicable amount) are not being offered to that
Lender in the relevant market for such Interest Period or (ii) the LIBOR Basis
for such proposed LIBOR Advance does not adequately cover the cost to such
Lender of making and maintaining such proposed LIBOR Advance for such Interest
Period, such Lender shall forthwith give notice thereof to the Company,
whereupon until such Lender notifies the Company that the circumstances giving
rise to such situation no longer exist, the obligation of such Lender to make
LIBOR Advances shall be suspended.

         Section 9.2. Illegality. If any applicable law, rule or regulation, or
any change therein or adoption thereof, or interpretation or administration
thereof by any governmental authority, central bank or comparable agency charged
with the interpretation or administration thereof, or compliance by any Lender
(or its LIBOR Lending Office) with any request or directive (whether or not
having the force of law) of any such authority, central bank or comparable
agency, shall make it unlawful or impossible for such Lender (or its LIBOR
Lending Office) to make, maintain or fund its LIBOR Advances, such Lender shall
so notify the Company and the Administrative Lender. Before giving any notice to
the Company pursuant to this Section, the notifying Lender shall designate a
different LIBOR 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 the
Lender, be materially disadvantageous to the Lender. Upon receipt of such
notice, notwithstanding anything contained in Article II hereof, the Company
shall repay in full the then outstanding principal amount of each LIBOR Advance
owing to the

                                      -45-
<PAGE>   51
notifying Lender, together with accrued interest thereon, on either (a) the last
day of the Interest Period applicable to such Advance, if the Lender may
lawfully continue to maintain and fund such Advance to such day, or (b)
immediately, if the Lender may not lawfully continue to fund and maintain such
Advance to such day. Concurrently with repaying each affected LIBOR Advance
owing to such Lender, notwithstanding anything contained in Article II hereof,
the 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, and such Base Rate Advance shall be payable on the same date or dates
as the affected LIBOR Advances of such Lender would have otherwise been due and
payable but for this Section 9.2.

         Section 9.3. Increased Costs.

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

                  (i) shall subject a Lender (or its LIBOR Lending Office) to
         any tax (net of any tax benefit engendered thereby) with respect to its
         LIBOR Advances or its obligation to make such Advances, or shall change
         the basis of taxation of payments to a Lender (or to its LIBOR Lending
         Office) of the principal of or interest on its LIBOR Advances or in
         respect of any other amounts due under this Agreement, as the case may
         be, or its obligation to make such Advances (except for changes in the
         rate of tax on the overall net income, net worth or capital of the
         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), 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 shall impose on the
         Lender (or its LIBOR Lending Office) or on the United States market for
         certificates of deposit or the London interbank market any other
         condition affecting its LIBOR 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) of making or maintaining any LIBOR Advances, or to
reduce the amount of any sum received or receivable by a Lender (or its LIBOR
Lending Office) with respect thereto, by an amount deemed by a Lender to be
material, then, within 15 days after demand by a Lender, the Company agrees to
pay to such Lender such additional amount as will compensate such Lender for
such increased costs or reduced amounts, subject to Section 10.9 hereof. The
affected Lender will as soon as practicable notify the 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 and will designate a different
LIBOR Lending Office or other lending office if such designation will avoid the
need for, or reduce

                                      -46-
<PAGE>   52
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 and setting forth the additional amounts to be paid to it hereunder and
calculations therefor shall be conclusive in the absence of manifest error. In
determining such amount, a Lender may use any reasonable averaging and
attribution methods. If a Lender demands compensation under this Section, the
Company may at any time, upon at least five Business Days' prior notice to the
Lender, after reimbursement to the Lender by the Company in accordance with this
Section of all costs incurred, prepay in full the then outstanding LIBOR
Advances of the Lender, together with accrued interest thereon to the date of
prepayment, along with any reimbursement required under Section 2.9 hereof.
Concurrently with prepaying such LIBOR Advances, the Company shall borrow a Base
Rate Advance from the Lender, and the 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, and such Base Rate Advance shall be
payable on the same date or dates as the LIBOR Advances of such Lender would
have otherwise been due and payable but for this Section 9.3.

         Section 9.4. Base Rate Advances Rather than LIBOR Advances. If notice
has been given pursuant to Section 9.1, 9.2 or 9.3 hereof suspending the
obligation of a Lender to make LIBOR Advances, or requiring LIBOR Advances of a
Lender to be repaid or prepaid, then, unless and until the Lender notifies the
Company that the circumstances giving rise to such repayment no longer apply,
all Advances which would otherwise be made by such Lender as LIBOR Advances
shall be made instead as Base Rate Advances, which shall be payable on the same
date or dates as the LIBOR Advances made by the other Lenders.

                                    ARTICLE X

                                  MISCELLANEOUS

         Section 10.1. Amendments and Waivers. No amendment or waiver of any
provision of this Agreement or any other Loan Papers, nor consent to any
departure by the Company or any of its Subsidiaries therefrom, shall be
effective unless the same shall be in writing and signed by the Administrative
Lender with the consent of the Majority Lenders, and then any such waiver or
consent shall be effective only in the specific instance and for the specific
purpose for which given; provided, however, that no amendment, waiver, or
consent shall, unless in writing and signed by all of the Lenders, (a) increase
the Commitment, (b) reduce any principal, interest, fees, or other amounts
payable hereunder, or waive any Event of Default under Section 7.1(a) hereof,
(c) postpone any date fixed for any payment of principal, interest, fees, or
other amounts payable hereunder, (d) release any collateral or guaranties
securing the Company's obligations hereunder, other than releases contemplated
by the Loan Papers, (e) change the meaning of Specified Percentage or the number
of Lenders required to take any action hereunder, or (f) amend this Section. No
amendment, waiver, or consent shall affect the Rights or duties of the
Administrative Lender under any Loan Papers, unless it is in writing and signed
by the Administrative Lender in addition to the requisite number of Lenders.

communications hereunder will be effective when so personally delivered or sent
by telecopy or telex, or five days after being so mailed; provided, however,

given pursuant to Article II hereof, and agrees to indemnify and hold harmless
the Administrative Lender and Lenders for any and all liabilities, obligations,
losses, damages, penalties, actions, judgments, suits, claims, costs, and
expenses resulting, directly or indirectly, from acting upon any such notice.

         Section 10.3. Parties in Interest. All covenants and agreements
contained in this Agreement and all other Loan Papers shall bind and inure to
the benefit of the respective successors and assigns of the parties hereto. The
Lenders may from time to time assign or transfer their interests hereunder
pursuant to Section 10.4 hereof. The Company may not assign or transfer its
Rights or obligations hereunder without the prior written consent of all
Lenders.

         Section 10.4. Assignments and Participations.

         (a) Each Lender may assign its Rights and obligations as a Lender under
the Loan Papers to one or more Eligible Assignees, pursuant to an assignment
substantially in the form of Exhibit "F" hereto, so long as (i) each assignment
shall be of a constant, and not a varying, percentage of all Rights and
obligations thereunder, (ii) the Eligible Assignee or the Lender entering into
such assignment, as determined between such Persons, shall deliver to the
Administrative Lender a processing fee of $3,500, and (iii) the amount of the
Commitment, 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 the lesser of (A) than $5,000,000
and which is an integral multiple of $1,000,000, or (B) the aggregate amount of
the Commitment, Advances and Reimbursement Obligations owned by the Lender
entering into such Assignment. Within five Business Days after notice of any
such assignment, the Company shall execute and deliver to the Administrative
Lender, in exchange for the Note issued to such Lender, new Notes to the order
of such Lender and its assignee in amounts equal to their respective Specified
Percentages of the Commitment. Such new Notes shall be dated the effective date
of the assignment. It is specifically acknowledged and agreed that on and after
the effective date of each assignment, the assignee shall be a party hereto and
shall have the Rights and obligations of a Lender under the Loan Papers.

         (b) Each Lender may sell participations to one or more banks or other
entities in all or any of its Rights and obligations under the Loan Papers;
provided, however, that (i) such Lender's

                                      -49-
<PAGE>   55
obligations under the Loan Papers shall remain unchanged, (ii) such Lender shall
remain solely responsible to the other parties hereto for the performance of
such obligations, (iii) such Lender shall remain the holder of its Note for all
purposes of the Loan Papers, (iv) the participant shall be granted the Right to
vote on or consent to only those matters described in subsections (a) through
(d) of Section 10.1 hereof, and (v) the Company, Administrative Lender, and
other Lenders shall continue to deal solely and directly with such Lender in
connection with its Rights and obligations under the Loan Papers.

         (c) Any Lender may, in connection with any assignment or participation,
or proposed assignment or participation, disclose to the assignee or
participant, or proposed assignee or participant, any information relating to
the Company or any of its Subsidiaries furnished to such Lender by or on behalf
of the Company or its Subsidiaries; provided, however, that, prior to any such
disclosure, the assignee or participant or proposed assignee or participant
shall agree to preserve the confidentiality of any confidential information
received by it from such Lender.

         (d) Notwithstanding any other provision set forth in this Agreement,
any Lender may at any time create a security interest in all or any portion of
its Rights under this Agreement (including, without limitation, the Advances
owing to it and the Note or Notes held by it) in favor of any Federal Reserve
Bank in accordance with Regulation A of the Board of Governors of the Federal
Reserve System.

         (e) If the Company receives notice from any Lender requesting increased
costs or additional amounts under Section 2.8 or 10.7, the Company shall have
the right, unless such Lender has removed or cured the conditions which resulted
in the obligation to pay such increased costs or additional amounts or agreed to
waive and otherwise forego any right it may have to any payments therein
provided, to replace in its entirety such Lender (the "Replaced Lender"), upon
prior written notice to Administrative Lender and such Replaced Lender, with one
or more Eligible Assignees acceptable to the Administrative Lender (which
acceptance shall not be unreasonably withheld), pursuant to the provisions of
this Section 10.4; provided, however, that nothing herein contained shall
relieve the Company of its obligation to pay any such increased costs or
additional amounts to the extent incurred prior to the replacement of the
applicable Lender and not reduced or omitted by the replacement of the
applicable Lender.

         Section 10.5. Sharing of Payments. If any Lender shall obtain any
payment (whether voluntary, involuntary, through 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 the Company, such Lender shall forthwith
purchase participations in Advances made by the other Lenders as shall be
necessary to share the excess payment pro rata according to Specified
Percentages with each of them; provided, however, that if any of such excess
payment is thereafter recovered from the purchasing Lender, its purchase from
each Lender shall be rescinded and each Lender shall repay the purchase price to
the extent of such recovery together with any interest or other amount paid or
payable by the purchasing Lender in respect of the total amount so recovered
according to Specified Percentages. The Company agrees that any Lender so
purchasing a participation from another Lender pursuant to this Section may, to
the fullest extent permitted by Applicable Law, 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 the Company in the amount of
such participation.

         Section 10.6. Right of Set-off. Upon the occurrence and during the
continuance of any Event of Default, each Lender is hereby authorized at any
time and from time to time, to the fullest extent permitted by Applicable Law,
to set-off and apply any and all deposits (general or special, time or demand,
provisional or final) at any time held and other indebtedness at any time owing
by such Lender to or for the credit or the account of the Company against any
and all of the obligations of the Company now or hereafter existing under this
Agreement and the other Loan Papers, whether or not such Lender shall have made
any demand under this Agreement or the other Loan Papers, and even if such
obligations are unmatured. Each Lender shall promptly notify the Company after
any such set-off and application, provided that the failure to give such notice
shall not affect the validity of such set-off and application. The Rights of
each Lender under this Section are in addition to other Rights (including,
without limitation, other Rights of set-off) which each Lender may have.

         Section 10.7. Costs, Expenses, and Taxes.

         (a) The Company agrees to pay on demand (i) all costs and expenses of
the Administrative Lender in connection with the preparation, negotiation, and
administration of any Loan Papers, including without limitation the reasonable
fees and out-of-pocket expenses of counsel for the Administrative Lender, (ii)
all reasonable costs and expenses (including reasonable attorneys' fees and
expenses) of the Administrative Lender in connection with modification,
amendment, waiver, or release of any Loan Papers, and (iii) all costs and
expenses (including reasonable attorneys' fees and expenses) of the
Administrative Lender, Lenders, and Issuing Bank in connection with enforcement
of any Loan Papers.

         (b) In addition, the Company shall pay any and all stamp, debt, and
other Taxes payable or determined to be payable in connection with any payment
hereunder (other than Taxes on the overall net income of the Administrative
Lender, any Lender, or the Issuing Bank or Taxes imposed by foreign Laws or as a
result of any Lender being organized under the laws of a jurisdiction outside of
the United States), or the execution, delivery, or recordation of any Loan
Papers, and agrees to save the Administrative Lender, Lenders, and Issuing Bank
harmless from and against any and all liabilities with respect to, or resulting
from any delay in paying or omission to pay any Taxes in accordance with this
Section, including any penalty, interest, and expenses relating thereto. All
payments by the Company or any Subsidiary under any Loan Papers shall be made
free and clear of and without deduction for any present or future Taxes (other
than Taxes on the overall net income of the Administrative Lender, any Lender,
or the Issuing Bank) of any nature now or hereafter existing, levied, or
withheld, including all interest, penalties, or similar liabilities relating
thereto. If the Company or any Subsidiary shall be required by Applicable Law to
deduct or to withhold any Taxes from or in respect of any amount payable
hereunder, (i) the amount so payable shall be increased to the extent necessary
so that, after making all required deductions and withholdings (including Taxes
on amounts payable to the Administrative Lender, any Lender, or the Issuing Bank
pursuant to this sentence), the payee receives an amount equal to the sum it
would have received had no such deductions or withholdings been made, (ii) the
Company or such Subsidiary shall make such deductions or withholdings, and (iii)
the Company or such Subsidiary shall pay the full amount deducted or withheld to
the relevant taxing authority in accordance with Applicable Law. Any Lender
claiming any additional amounts payable pursuant to this Section 10.7 shall use
reasonable commercial efforts to change the jurisdiction of its lending office
if the making of such change would avoid the need for or materially reduce the
amount of any such additional amounts which may

                                      -51-
<PAGE>   57
thereafter accrue and if, in the reasonable opinion of such Lender, such change
in lending office would not be contrary to such Lender's normal banking
practices or be disadvantageous to such Lender.

         (c) Each Lender which is not a United States Person hereby agrees that:

                  (i) it shall, no later than the date hereof (or, in the case
         of a Lender which becomes a party hereto pursuant to Section 11.6 after
         the date hereof, the date upon which such Lender becomes a party
         hereto) deliver to the Company:

                  (A)      if any lending office is located in the United States
                           of America, two (2) accurate and complete signed
                           originals of Internal Revenue Service Form 4224 or
                           any successor thereto ("Form 4224"),

                  (B)      if any lending office is located outside the United
                           States of America, two (2) accurate and complete
                           signed originals of Internal Revenue Service Form
                           1001 or any successor thereto ("Form 1001").

         in each case indicating that such Lender is on the date of delivery
         thereof entitled to receive payments of principal, interest and fees
         for the account of such lending office or lending offices under this
         Agreement free from withholding of United States Federal income tax;

                  (ii) if at any time such Lender changes its lending office or
         lending offices or selects an additional lending office it shall, at
         the same time or reasonably promptly thereafter but only to the extent
         the forms previously delivered by it hereunder are no longer effective,
         deliver to the Company, in replacement for the forms previously
         delivered by it hereunder:

                  (A)      if such changed or additional lending office is
                           located in the United States of America, two (2)
                           accurate and complete signed originals of Form 4224;
                           or

                  (B)      otherwise, two (2) accurate and complete signed
                           originals of Form 1001,

         in each case indicating that such Lender is on the date of delivery
         thereof entitled to receive payments of principal, interest and fees
         for the account of such changed or additional lending office under this
         Agreement free from withholding of United States Federal income tax;

                  (iii) it shall, before or promptly after the occurrence of any
         event (including the passing of time but excluding any event mentioned
         in clause (ii) above) requiring a change in the most recent Form 4224
         or Form 1001 previously delivered by such Lender and if the delivery of
         the same be lawful, deliver to the Company, two (2) accurate and
         complete original signed copies of Form 4224 or Form 1001 in
         replacement for the forms previously delivered by such Lender;

                  (iv) it shall, promptly upon the request of the Company,
         deliver to the Company such other forms or similar documentation as may
         be required from time to time by any applicable law, treaty, rule or
         regulation in order to establish such Lender's tax status for
         withholding purposes; and

                                      -52-
<PAGE>   58
                  (v) it shall notify the Company, within 30 days after any
         event (including an amendment to, or a change in any applicable law or
         regulation or in the written interpretation thereof by any regulatory
         authority or any judicial authority, or by ruling applicable to such
         Lender of any governmental authority charged with the interpretation or
         administration of any law) shall occur that results in such Lender no
         longer being capable of receiving payments without any deduction or
         withholding of United States federal income tax.

         SECTION 10.8. INDEMNIFICATION BY COMPANY. THE COMPANY AGREES TO
INDEMNIFY, DEFEND, AND HOLD HARMLESS THE ADMINISTRATIVE LENDER, THE LENDERS, THE
ISSUING BANK, AND THEIR AFFILIATES, DIRECTORS, OFFICERS, AGENTS, EMPLOYEES, AND
REPRESENTATIVES, FROM AND AGAINST ANY AND ALL LIABILITIES, OBLIGATIONS, LOSSES,
DAMAGES, PENALTIES, ACTIONS, JUDGMENTS, SUITS, CLAIMS, COSTS, EXPENSES, AND
DISBURSEMENTS OF ANY KIND OR NATURE WHATSOEVER WHICH MAY BE IMPOSED ON, INCURRED
BY OR ASSERTED AGAINST ANY OF THEM IN ANY WAY RELATING TO OR ARISING OUT OF ANY
LOAN PAPERS (INCLUDING IN CONNECTION WITH OR AS A RESULT, IN WHOLE OR IN PART,
OF THE NEGLIGENCE OF ANY OF THEM), ANY TRANSACTION RELATED HERETO OR THERETO, OR
ANY ACT, OMISSION, OR TRANSACTION OF THE COMPANY AND ITS AFFILIATES, OR ANY OF
THEIR DIRECTORS, OFFICERS, AGENTS, EMPLOYEES, OR REPRESENTATIVES; PROVIDED,
HOWEVER, THAT THE ADMINISTRATIVE LENDER, LENDERS, AND ISSUING BANK SHALL NOT BE
INDEMNIFIED, DEFENDED, AND HELD HARMLESS PURSUANT TO THIS SECTION FOR ANY LOSSES
OR DAMAGES WHICH THE COMPANY PROVES WERE CAUSED BY THE INDEMNIFIED PARTY'S
WILLFUL MISCONDUCT OR GROSS NEGLIGENCE.

         Section 10.9. Rate Provision. It is not the intention of any party to
any Loan Papers to make an agreement violative of the Applicable Laws of any
applicable jurisdiction relating to usury. In no event shall the Company or any
of its Subsidiaries be obligated to pay 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 the Company. In determining
whether or not the interest paid or payable, under any specific contingency,
exceeds the Maximum Amount, the Company and Lenders shall, to the maximum extent
permitted under Applicable Laws, (i) characterize any nonprincipal payment as an
expense, fee or premium rather than as interest, (ii) exclude voluntary
prepayments and the effect thereof, and (iii) amortize, prorate, allocate and
spread in equal parts, the total amount of interest throughout the entire
contemplated term of the Obligation so that the interest rate is uniform
throughout the entire term of the Obligation; provided that if the Obligation is
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 the Company the amount of
such excess or credit the amount of such excess against the total principal
amount owing, and, in such event, no Lender shall be subject to any penalties
provided by any Applicable Laws for contracting for, charging or receiving
interest in excess of the Maximum Amount. This Section 10.9 shall control every
other

                                      -53-
<PAGE>   59
provision of all agreements among the parties to this Agreement pertaining to
the transactions contemplated by or contained in the Loan Papers.

         Section 10.10. Severability. If any provision of any Loan Papers is
held to be illegal, invalid, or unenforceable under present or future Applicable
Laws during the term thereof, such provision shall be fully severable, the
appropriate Loan Paper shall be construed and enforced as if such illegal,
invalid, or unenforceable provision had never comprised a part thereof, and the
remaining provisions thereof shall remain in full force and effect and shall not
be affected by the illegal, invalid, or unenforceable provision or by its
severance therefrom. Furthermore, in lieu of such illegal, invalid, or
unenforceable provision there shall be added automatically as a part of such
Loan Paper a legal, valid, and enforceable provision as similar in terms to the
illegal, invalid, or unenforceable provision as may be possible.

         Section 10.11. Exceptions to Covenants. Neither the Company nor any of
its Subsidiaries shall be deemed to be permitted to take any action or to fail
to take any action that is permitted as an exception to any covenant in any Loan
Papers, or that is within the permissible limits of any covenant, if such action
or omission would result in a violation of any other covenant in any Loan
Papers.

         Section 10.12. Counterparts. This Agreement and the other Loan Papers
may be executed in any number of counterparts, all of which taken together shall
constitute one and the same instrument. In making proof of any such agreement,
it shall not be necessary to produce or account for any counterpart other than
one signed by the party against which enforcement is sought.

         Section 10.13. No Novation. Except for Liens expressly released in
connection herewith, the execution, delivery and effectiveness of this Agreement
shall not extinguish the obligations for the payment of money outstanding under
the Prior Credit Agreement (as defined in the recitals hereof) or discharge or
release the Lien or priority of any security agreement, any pledge agreement or
any other security therefor. Nothing herein contained shall be construed as a
substitution or novation of the Obligations outstanding under the Prior Credit
Agreement or instruments securing the same, which shall remain in full force and
effect, except as modified hereby or by instruments executed concurrently
herewith. Nothing expressed or implied in this Agreement, or any other document
contemplated hereby shall be construed as a release or other discharge of the
Company under the Prior Credit Agreement or any guarantor or pledgor under any
Loan Paper (as such term is defined in the Prior Credit Agreement) from any of
its obligations and liabilities thereunder. The Prior Credit Agreement and such
Loan Papers shall remain in full force and effect, until and except as modified
hereby or in connection herewith.

         Section 10.14. Purchase by Lenders. Simultaneously with the
satisfaction of the conditions precedent to effectiveness set forth in Section
4.1 hereof, each Lender a party hereto and not a Prior Lender shall be deemed to
have purchased without recourse an amount of each of the Prior Lender's
outstanding Advances and Reimbursement Obligations under the prior Credit
Agreement such that after giving effect to this Agreement, the percentage of
each Lender's Commitment hereunder which has been utilized will be ratable in
accordance with their Specified Percentage. Each Prior Lender warrants that its
portion of the outstanding Advances and

                                      -54-
<PAGE>   60
Reimbursement Obligations under the Prior Credit Agreement being sold pursuant
to this Section 10.14 is being sold free and clear of any adverse claims.

         SECTION 10.15. GOVERNING LAW; WAIVER OF JURY TRIAL.

         (a) THIS AGREEMENT AND ALL OTHER LOAN PAPERS SHALL BE DEEMED TO BE
CONTRACTS MADE IN DALLAS, TEXAS, AND SHALL BE GOVERNED BY AND CONSTRUED IN
ACCORDANCE WITH THE LAWS OF THE STATE OF TEXAS (WITHOUT GIVING EFFECT TO
CONFLICT OF LAWS) AND THE UNITED STATES OF AMERICA. WITHOUT EXCLUDING ANY OTHER
JURISDICTION, THE COMPANY AGREES THAT THE STATE AND FEDERAL COURTS OF TEXAS
LOCATED IN DALLAS, TEXAS, WILL HAVE JURISDICTION OVER PROCEEDINGS IN CONNECTION
HEREWITH. TO THE MAXIMUM EXTENT PERMITTED BY LAW, THE COMPANY HEREBY WAIVES ANY
RIGHT THAT THEY MAY HAVE TO A TRIAL BY JURY OF ANY DISPUTE (WHETHER A CLAIM IN
TORT, CONTRACT, EQUITY, OR OTHERWISE) ARISING UNDER OR RELATING TO THIS
AGREEMENT, THE OTHER LOAN PAPERS, OR ANY RELATED MATTERS, AND AGREES THAT ANY
SUCH DISPUTE SHALL BE TRIED BEFORE A JUDGE SITTING WITHOUT A JURY.

         (b) THE COMPANY HEREBY WAIVES PERSONAL SERVICE OF ANY LEGAL PROCESS
UPON IT. UNDER THE LOAN PAPERS, IN ADDITION, THE COMPANY AGREES THAT SERVICE OF
PROCESS MAY BE MADE UPON IT BY REGISTERED MAIL (RETURN RECEIPT REQUESTED)
DIRECTED TO THE COMPANY AT ITS ADDRESS DESIGNATED FOR NOTICE UNDER THIS
AGREEMENT AND SERVICE SO MADE SHALL BE DEEMED TO BE COMPLETED FIVE DAYS AFTER
DEPOSIT IN THE UNITED STATES MAIL. NOTHING IN THIS SECTION SHALL AFFECT THE
RIGHT OF THE ADMINISTRATIVE LENDER OR ANY LENDER TO SERVE LEGAL PROCESS IN ANY
OTHER MANNER PERMITTED BY LAW.

         SECTION 10.16. ENTIRE AGREEMENT. THIS AGREEMENT AND THE OTHER LOAN
PAPERS REPRESENT THE FINAL AGREEMENT BETWEEN THE PARTIES AND MAY NOT BE
CONTRADICTED BY EVIDENCE OF PRIOR, CONTEMPORANEOUS OR SUBSEQUENT ORAL AGREEMENT
OF THE PARTIES. THERE ARE NO UNWRITTEN ORAL AGREEMENTS BETWEEN THE PARTIES.
