                         STAPLES, INC. AND SUBSIDIARIES

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS


NOTE 1  -  BASIS OF PRESENTATION

The accompanying interim unaudited consolidated financial statements include the
accounts of Staples, Inc. and its wholly owned subsidiaries (the "Company"). All
intercompany accounts and transactions are eliminated in consolidation.

These financial statements have been prepared in accordance with generally
accepted accounting principles for interim financial information and with the
instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do
not include all of the information and footnotes required by generally accepted
accounting principles for complete financial statements. In the opinion of
management, such interim statements reflect all adjustments (consisting of
normal recurring accruals) necessary to present fairly the financial position
and the results of operations and cash flows for the interim periods presented.
The results of operations for the interim periods are not necessarily indicative
of the results to be expected for the full year. These financial statements
should be read in conjunction with the audited consolidated financial statements
and footnotes included in the Company's Annual Report on Form 10-K dated April
25, 1997 for the year ended February 1, 1997.

NOTE 2 - COMPUTATION OF EARNINGS PER SHARE

Average common and common equivalent shares used in computing earnings per share
include approximately 5,481,000 and 6,626,000 shares for the quarters ended
November 1, 1997 and November 2, 1996, respectively, as a result of applying the
treasury stock method to outstanding stock options.

In February 1997, the Financial Accounting Standards Board issued Statement No.
128, "Earnings per Share" ("Statement 128"), which must be adopted in the fourth
quarter ending January 31, 1998. At that time, the Company will change the
method currently used to compute earnings per share and restate all prior
periods. Under the new requirements for calculating primary earnings per share,
the dilutive effect of stock options will be excluded. The impact of Statement
128 on the calculation of primary and fully diluted earnings per share for the
quarters ending November 1, 1997 and November 2, 1996 is not material.

NOTE 3 - ACQUISITIONS

On May 6, 1997 and May 7, 1997, the Company acquired from Kingfisher PLC its
interests in Staples UK and MAXI-Papier-Markt-GmbH ("Maxi"). As a result of the
acquisitions, the Company's ownership interest of Staples UK increased to 100%
and its ownership of Maxi increased to approximately 93%. Staples UK and Maxi
operate a chain of office products superstores in the UK and Germany,
respectively. The aggregate cash purchase price of approximately $57 million was
generated through additional borrowings under the Company's existing revolving
credit. The transactions were accounted for in accordance with the purchase
method of accounting and accordingly, the results of operations of Staples UK
and Maxi have been included in the Company's consolidated financial statements
from May 6, 1997


                                     Page 6


<PAGE>   7
and May 7, 1997, respectively. Unaudited pro forma net income and earnings per
share, assuming the acquisitions had been consummated as of the beginning of
fiscal year 1996, were $63,008,000 and $0.37, respectively, for the nine months
ended November 1, 1997, and $52,612,000 and $0.32, respectively, for the nine
months ended November 2, 1996. The excess of the purchase price over the fair
market value of the acquired assets has been recorded as goodwill and is being
amortized on a straight line basis over 40 years.

NOTE 4 - RECENT DEVELOPMENTS

On July 2, 1997, after an unfavorable ruling by the United States District
Court, Staples announced that it had terminated its Agreement and Plan of Merger
with Office Depot, Inc. ("Office Depot").

The Company charged to expense merger costs of $29,665,000 for the nine months
ended November 1, 1997. These costs relate primarily to legal, accounting,
transaction related costs, such as filing fees, and consulting fees incurred in
connection with the proposed merger with Office Depot. Excluding the merger
costs, earnings per share would have been $0.50 for the nine months ended
November 1, 1997.

NOTE 5 - SUBSEQUENT EVENT

On November 13, 1997, the Company entered into a new $350,000,000 five-year
revolving credit agreement with a syndicate of banks. Borrowings made pursuant
to this facility will bear interest at either the lead bank's prime rate,
one-half of one percent (1/2%) per annum above the Federal Funds Effective Rate,
or the LIBOR rate plus a percentage spread based upon certain defined ratios and
the Company's debt rating.

NOTE 6 - NEW ACCOUNTING PRONOUNCEMENTS

In June 1997, the Financial Accounting Standards Board issued Statement No. 130,
"Reporting Comprehensive Income" ("Statement 130") and Statement No. 131,
"Disclosure about Segments of an Enterprise and Related Information" ("Statement
131") effective fiscal year 1998. Statement 130 requires comprehensive income
items recorded in stockholders' equity to be shown in a separate financial
statement. Statement 131 supersedes FASB Statement No. 14, "Financial Reporting
for Segments of a Business Enterprise". Statement 131 establishes standards for
the way that public companies report selected information about operating
segments in annual financial statements and requires that those companies report
selected information about segments in interim financial reports issued to
shareholders. The Company has not determined the effects, if any, that Statement
130 and Statement 131 will have on its consolidated financial statements.

                         STAPLES, INC. AND SUBSIDIARIES
                     MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                  FINANCIAL CONDITION AND RESULTS OF OPERATIONS


RESULTS OF OPERATIONS

SALES. Sales increased 31% to $1,414,224,000 in the quarter ended November 1,
1997 from $1,078,820,000 in the quarter ended November 2, 1996 and increased 30%
to $3,631,085,000 for the nine months ended November 1, 1997 compared to
$2,803,676,000 for the nine months ended November 2, 1996. This growth is
attributable to an increase in the number of open stores, increased sales in
existing stores and in the delivery and contract stationer segments, and the
consolidation of the sales of Staples UK and Maxi. Comparable store and delivery
hub sales for the quarter ended November 1, 1997 increased 10% over the quarter
ended November 2, 1996, and increased 10% for the nine months ended November 1,
1997 versus the nine months ended November 2, 1996. Comparable sales in the
contract stationer segment increased 13% for the quarter ended November 1, 1997
versus the quarter ended November 2, 1996 and increased 13% for the nine months
ended November 1, 1997 versus the nine months ended November 2, 1996. The
Company had 720 stores open as of November 1, 1997 compared to 550 stores as of
November 2, 1996 and 557 stores open as of February 1, 1997. The November 1,
1997 total includes 38 stores opened during the three months ended November 1,
1997 and 108 stores opened and one store closed during the nine months ended
November 1, 1997; and 56 stores that were acquired in the UK and Germany as a
result of the acquisitions of Staples UK and Maxi, in the nine months ended
November 1, 1997.

GROSS PROFIT. Gross profit as a percentage of sales was 24.3% and 23.9% for the
three and nine months ended November 1, 1997, respectively, as compared to 23.9%
and 23.4%, respectively, for the same periods in the prior year. The increase in
gross profit rate for the three and nine months ended November 1, 1997 was
primarily due to improved margins in the retail and delivery business segments
due to lower product costs from vendors as a result of increased purchase
discounts and changes in product mix as well as the leveraging of distribution
center and delivery costs over a larger sales base. This was partially offset by
decreases in the margin rates in the retail store segment, due to price
reductions as well as an increase in the sales of computer hardware (which
generate a lower margin rate than other categories) from 7.9% and 7.5% of sales
for the three and nine months ended November 2, 1996, to 9.9% and 7.7% of sales
for the three and nine months ended November 1, 1997, respectively.

OPERATING AND SELLING EXPENSES. Operating and selling expenses, which consist of
payroll, advertising and other store operating costs, increased as a percentage
of sales in the three and nine months ended November 1, 1997 to 15.2% and 15.6%
respectively, as compared to 14.7% and 15.4% for the same periods in the prior
year. The increase is primarily due to the acquisitions of Staples UK and Maxi,
which have higher costs as a percentage of sales, as well as planned increases
in advertising and circulars. This increase was partially offset by increased
leveraging of fixed store payroll expenses and other fixed store operating costs
as store sales have increased.

Staples UK and Maxi store expenses are higher as a result of their earlier stage
of development. While most store expenses vary proportionately with sales, there
is a fixed cost component. Because new stores


                                     Page 8


<PAGE>   9




typically generate lower sales than the Company average, the fixed cost
component results in higher store operating and selling expenses as a percentage
of sales in these stores during their start-up period. During periods when new
store openings as a percentage of the base are higher, store operating and
selling expenses as a percentage of sales may increase. In addition, as the
store base matures, the fixed cost component of operating expenses is leveraged
over an increased level of sales, resulting in a decrease in store operating and
selling expenses as a percentage of sales.

PRE-OPENING EXPENSES. Pre-opening expenses relating to new store openings, which
consist primarily of salaries, supplies, marketing and occupancy costs, are
expensed by the Company as incurred and therefore fluctuate from period to
period depending on the timing and number of new store openings. Pre-opening
expenses averaged $73,000 and $74,000, respectively, per store for the three and
nine months ended November 1, 1997, respectively, as compared to $69,000 and
$72,000 per store for the same periods in the prior year.

GENERAL AND ADMINISTRATIVE EXPENSES. General and administrative expenses for the
three and nine months ended November 1, 1997 increased as a percentage of sales
to 3.4% and 3.6%, respectively, as compared to 3.2% and 3.4%, respectively, for
the same periods in the prior year. This increase was primarily due to the
acquisitions of Staples UK and Maxi, which have higher costs as a percentage of
sales; as their store base matures overhead expenses should decrease as a
percentage of sales. This increase was partially offset by the Company's ability
to increase sales without proportionately increasing overhead expenses in its
core retail business. In addition, the Company has made investments in the
Company's information systems staffing and infrastructure, which the Company
believes will reduce costs as a percentage of sales in future years.

INTEREST AND OTHER EXPENSE, NET. Net interest and other expense for the three
and nine months ended November 1, 1997 was $6,466,000 and $16,902,000 as
compared to $5,384,000 and $14,577,000, respectively, for the same periods in
the prior year. The interest expense relates primarily to increased borrowings
which funded the increase in store inventories related to new store openings,
expanded product assortment, and improvements in in-stock levels; the
acquisition of fixed assets for new stores opened and remodeled; and continued
investments in the information systems and distribution center infrastructure.

MERGER-RELATED COSTS. The Company charged to expense in the nine months ended
November 1, 1997 certain non-recurring costs consisting primarily of legal,
accounting, transaction related costs, such as filing fees, and consulting fees
incurred in connection with the proposed merger with Office Depot, Inc.

EQUITY IN LOSS OF AFFILIATES. The Company's equity in loss of affiliates was
$5,953,000 for the nine months ended November 1, 1997 as compared to $3,520,000
and $11,262,000, respectively, for the three and nine months ended November 2,
1996. The Company recorded no equity in loss of affiliates for the three months
ended November 1, 1997, due to the acquisition of Staples UK and Maxi on May 6,
1997 and May 7, 1997. As a result of the acquisitions, the Company's ownership
interest of Staples UK increased to 100% and its ownership of Maxi increased to
approximately 93%. The transactions were accounted for as purchases and the
consolidated results of these entities are reflected in the Company's financial
statements since the date of acquisitions. Prior to the acquisitions, Staples UK
and Maxi were accounted for under the equity method which resulted in the
Company's share of losses from operations being included in Equity in Loss of
Affiliates. As of November 1, 1997, Staples UK and Maxi operated 40 and 17
stores, respectively.

LIQUIDITY AND CAPITAL RESOURCES

During the nine months ended November 1, 1997, cash and cash equivalents
increased by $129,460,000. The principal sources of cash consisted of cash
provided by financing activities of $166,917,000, which primarily represents an
increase in the borrowings under the existing revolving credit facility and cash
provided by operations of $173,026,000. The borrowings were primarily for the
acquisitions of Staples UK and Maxi for a total of $57,000,000 on May 6 and 7,
1997, respectively. The increase in accounts payable and accrued expenses
financed the increase in merchandise inventory related to new store openings and
expanded product assortments, while the remaining cash was generated from
operations. This was offset by cash used in investing activities of
$208,400,000, which includes capital expenditures of $139,826,000 primarily
incurred in connection with the opening of 108 new stores and cash used in the
acquisition of Staples UK and Maxi, net of cash acquired, of $77,808,000.

The Company expects to open approximately twenty-two stores in the last quarter
of fiscal 1997. Management estimates that the Company's cash requirements,
including pre-opening expenses, leasehold improvements and fixtures (net of
store inventory financed under vendor trade terms), will be approximately
$1,400,000 for each new store (excluding the cost of any acquisitions of lease
rights). Accordingly, the Company expects to use in excess of $30,800,000 for
store openings during this period. In addition, the Company plans to continue to
make investments in information systems, distribution centers and store remodels
to improve operational efficiencies and customer service, and may expend
additional funds to acquire businesses or lease rights from tenants occupying
retail space that is suitable for a Staples store. The Company expects to meet
these cash requirements through a combination of available cash, operating cash
flow and borrowings from its existing revolving line of credit.

The Company issued $200,000,000 of senior notes (the "Notes") on August 12, 1997
with an interest rate of 7.125% payable semi-annually on February 15 and August
15 of each year commencing on February 15, 1998. Net proceeds of approximately
$198,000,000 from the sale of the Company's Notes were used for repayment of
indebtedness under the Company's revolving credit agreement and for general
working capital purposes, including the financing of new store openings,
distribution facilities and corporate offices.

Effective November 13, 1997, the Company entered into a new revolving credit
facility, effective through November 2002, with a syndicate of banks which
provides up to $350,000,000 of borrowings. This agreement includes, among other
conditions and covenants, certain restrictive covenants including net worth
maintenance, minimum interest coverage and limitations on indebtedness, sales of
assets, and dividends. As of November 1, 1997, borrowings under the prior
revolving credit facility totaled $10,435,000. Total cash, short-term
investments and available revolving credit amounts totaled $612,422,000 as of
November 1, 1997.

The Company expects that its current cash and cash equivalents and funds
available under its revolving credit will be sufficient to fund its planned
store openings and other recurring operational cash needs for the next twelve to
eighteen months. The Company is continually evaluating financing possibilities,
and it may seek to raise additional funds through any one or a combination of
public or private debt or equity-related offerings, depending upon market
conditions, or through additional commercial bank debt arrangements.

FUTURE OPERATING RESULTS

This Quarterly Report on Form 10-Q contains a number of forward-looking
statements. There are a number of important factors that could cause the
Company's results to differ materially from those indicated by such
forward-looking statements. These factors include, without limitation, the
following:

The Company operates in a highly competitive marketplace, in which it competes
with a variety of retailers, dealers and distributors. The Company competes in
most of its geographic markets with other high-volume office supply chains that
are similar in concept to the Company in terms of store format, pricing strategy
and product selection, such as Office Depot and OfficeMax. The Company also
competes with independent dealers, contract stationers, mail order stationers,
warehouse clubs, mass merchandisers, consumer electronics retailers, computer
superstores and manufacturers, and other discount retailers. Some of the
Company's current and potential competitors in the office products industry are
larger than the Company and have substantially greater financial resources. No
assurance can be given that competition will not have an adverse effect on the
Company's business.

An important part of the Company's business plan is an aggressive store growth
strategy. The Company opened 115 stores in the United States and Canada in
fiscal 1996 and 108 stores in the first nine months of fiscal year 1997 and
plans to continue this aggressive store opening schedule in fiscal year 1998.
There can be no assurance that the Company will be able to identify and lease
favorable store sites, hire and train employees, and adapt its management and
operational systems to the extent necessary to fulfill its expansion plans. The
failure to open new stores in accordance with its growth plans could have a
material adverse impact on the Company's future sales and profits. Moreover, the
Company's expansion strategy is based in part on the continued addition of new
stores to its store network in existing markets to take advantage of economies
of scale in marketing, distribution and supervision costs; however, this can
result in the "cannibalization" of sales of existing stores. In addition, there
can be no assurance that the new stores opened by the Company will achieve sales
or profit levels commensurate with those of the Company's existing stores.

The Company has experienced and may experience in the future fluctuations in its
quarterly operating results. Moreover, there can be no assurance that Staples
will continue to realize the earnings growth experienced over recent years, or
that earnings in any particular quarter will not fall short of either a prior
fiscal quarter or investors' expectations. Factors such as the number of new
store openings (pre-opening expenses are expensed as incurred, and newer stores
are less profitable than mature stores), the extent to which new stores
"cannibalize" sales of existing stores, the mix of products sold, pricing
actions of competitors, the level of advertising and promotional expenses,
seasonality, and one-time charges associated with acquisitions or other events
could contribute to this quarterly variability. In addition, the Company's
expense levels are based in part on expectations of future sales levels, and a
shortfall in expected sales could therefore result in a disproportionate
decrease in the Company's net income.

The Company's business, including sales, number of stores and number of
employees, has grown dramatically over the past several years. In addition, the
Company has consummated a number of significant acquisitions in the last few
years, and may make additional acquisitions in the future. This internal growth,
together with the acquisitions made by the Company, have placed significant
demand on the management and operational systems of the Company. To manage its
growth effectively, the Company will be required to continue to upgrade its
operational and financial systems, expand its management team and increase and
manage its employee base.

The Company has a presence in international markets through its recently
acquired operations in Germany and the United Kingdom, and may seek to expand
into other international markets in the future. The Company's operations in
foreign markets are subject to risks similar to those affecting its US stores,
in addition to a number of risks inherent in foreign operations, including local
customs and competitive conditions, and foreign currency fluctuations. Staples'
foreign operations are currently unprofitable, and there can be no assurance
that they will become profitable.

The Company currently expects that its current cash and cash equivalents and
funds available under its revolving credit and will be sufficient to fund its
planned store openings and other operating cash needs for the next twelve to
eighteen months. However, there can be no assurance that the Company will not
require additional sources of financing prior to such time, as a result of
unanticipated cash needs or opportunities, an expanded growth strategy or
disappointing operating results. There also can be no assurance that the
additional funds required by the Company, whether within the next eighteen
months or thereafter, will be available to the Company on satisfactory terms.

                  (iii) Any Competitive Bid Quote shall be disregarded if it:

                    (A) is not substantially in the form of EXHIBIT D-1 attached
hereto or does not specify all of the information required by subsection (d)(ii)
of this ss.2.3.1;

                    (B) contains qualifying, conditional or similar language
(except that it may, in the case of a quote relating to more than one Interest
Period, contain the condition that the Bank will fund any one, but not more, of
the Competitive Bid Loans offered in such Competitive Bid Quote);

                    (C) proposes terms other than or in addition to those set
forth in the applicable Invitation for Competitive Bid Quotes; or

                    (D) arrives after the time set forth in subsection (d)(i) of
this ss.2.3.1.

             (e) NOTICE TO BORROWER. Not later than 10:30 a.m. (Boston time) on
the requested Drawdown Date, the Agent shall notify the Borrower of the terms of
all Competitive Bid Quotes submitted by the Banks in accordance with subsection
(d) of this ss.2.3.1. The Agent's notice to the Borrower shall specify (i) the
aggregate principal amount of Competitive Bid Loans for which offers have been
received for each Interest Period specified in the related Competitive Bid Quote
Request, and (ii) the respective principal amounts and Competitive Bid Rates so
offered.

                                      -23-


             (f) ACCEPTANCE AND NOTICE BY BORROWER. Not later than 11:00 a.m.
(Boston time) on the requested Drawdown Date, the Borrower shall notify the
Agent, and the Agent shall promptly notify each Bank with respect to its offer,
of the Borrower's acceptance or non-acceptance of the offers of which it was
notified pursuant to subsection (e) of this ss.2.3.1. In the case of an
acceptance, such notice shall (i) be substantially in the form of EXHIBIT D-2
attached hereto (a "Notice of Competitive Bid Borrowing"), (ii) be irrevocable
by the Borrower, and (iii) specify the aggregate principal amount of offers for
each Interest Period that are accepted. Each acceptance by the Borrower of
Competitive Bid Loans hereunder shall constitute a representation and warranty
by the Borrower that the conditions set forth in ss.ss.9 and 10 hereof have been
satisfied on the date of such acceptance. The Borrower may accept any
Competitive Bid Quote in whole or in part; provided that:

                    (A) the aggregate principal amount of each Competitive Bid
Loan may not exceed the applicable amount set forth in the related Competitive
Bid Quote Request,

                    (B) the aggregate principal amount of each Competitive Bid
Loan must be $2,000,000 or a larger multiple of $1,000,000, and

                    (C) acceptance of offers may only be made on the basis of
ascending Competitive Bid Rates.

             (g) ALLOCATION BY AGENT; USAGE OF COMMITMENTS. If offers are made
by two or more Banks with the same Competitive Bid Rates, for a greater
aggregate principal amount than the amount in respect of which offers are
accepted for the related Interest Period, the principal amount of Competitive
Bid Loans in respect of which such offers are accepted shall be allocated by the
Agent among such Banks as nearly as possible (in such multiples, not less than
$100,000 as the Agent may deem appropriate) in proportion to the aggregate
principal amounts of such offers. If any such Bank has indicated a minimum
acceptable Competitive Bid Loan in its Competitive Bid Request, and under the
procedures of this subsection (g), the Agent would have allocated to it an
amount less than such minimum, such Competitive Bid Quote will instead be deemed
to have been withdrawn. Determination by the Agent of the amounts of Competitive
Bid Loans and the allocation thereof shall be conclusive in the absence of
manifest error. The Agent shall, promptly after the funding of any Competitive
Bid Loan, notify the Banks thereof pursuant to a notice substantially in the
form of EXHIBIT D-3 attached hereto.

             (h) FUNDING OF COMPETITIVE BID LOANS. If, on or prior to the
Drawdown Date of any Competitive Bid Loan, the Total Commitment has not


<PAGE>   31
    

                                      -24-

terminated in full and if, on such Drawdown Date, the applicable conditions of
ss.ss.9 and 10 hereof are satisfied, the Bank or Banks whose offers the Borrower
has accepted will fund each Competitive Bid Loan so accepted as provided in
ss.2.4.1 hereof.

             ss.2.3.2. MAXIMUM COMPETITIVE BID LOANS; FUNDING LOSSES.

             (a) Notwithstanding any other provision herein to the contrary, at
no time shall the aggregate principal amount of Competitive Bid Loans
outstanding at any time exceed the Total Commitment MINUS the sum of (A) the
aggregate principal amount of Syndicated Loans outstanding at such time PLUS (B)
the aggregate principal amount of Swing Line Loans outstanding at such time PLUS
(C) the Maximum Drawing Amount PLUS (D) all Unpaid Reimbursement Obligations.

             (b) If after acceptance of any Competitive Bid Quote pursuant to
ss.2.3.1(f) hereof, the Borrower fails to borrow any Competitive Bid Loan so
accepted on the date specified therefor, the Borrower shall indemnify the Bank
funding such Loan against any loss or expense incurred by reason of the
liquidation or reemployment of deposits or other funds acquired by such Bank to
fund or maintain such unborrowed Competitive Bid Loans, including, without
limitation, compensation as provided in ss.4.10 hereof.

             ss.2.3.3. REPAYMENT OF COMPETITIVE BID LOANS. The principal of each
Competitive Bid Loan shall become absolutely due and payable by the Borrower on
the last day of the Interest Period relating thereto, and the Borrower hereby
absolutely and unconditionally promises to pay to the Agent, for the accounts of
the relevant Banks, on the last day of the Interest Period relating thereto the
principal amount of all such Competitive Bid Loans PLUS interest thereon at the
applicable Competitive Bid Rate. Subject to the terms of this Credit Agreement,
the Borrower may reborrow any amounts so repaid from time to time prior to the
Maturity Date.

             ss.2.4. FUNDS FOR REVOLVING CREDIT LOANS.

             ss.2.4.1. FUNDING PROCEDURES. Not later than 1:30 p.m. (Boston
time) on the proposed Drawdown Date of any Syndicated Loans or Competitive Bid
Loans, as applicable, each of the relevant Banks will make available to the
Agent, at the Agent's Head Office, in immediately available funds, the amount of
such Bank's Commitment Percentage of the amount of the requested Syndicated
Loans or the amount of such Bank's Competitive Bid Loan, as applicable. Upon
receipt from each Bank of such amount, and upon receipt of the documents
required by ss.ss.9 and 10 hereof and the satisfaction of the other conditions
set forth therein, to the extent applicable, the Agent will make


<PAGE>   32


                                      -25-


available to the Borrower the aggregate amount of such Revolving Credit Loans
made available to the Agent by the relevant Banks. The failure or refusal of any
Bank to make available to the Agent its Commitment Percentage of the requested
Syndicated Loans on any Drawdown Date shall not excuse any other Bank from
making available to the Agent the amount of such other Bank's Commitment
Percentage of any requested Syndicated Loans.

             ss.2.4.2. ADVANCES BY AGENT. The Agent may, unless notified to the
contrary by any Bank prior to a Drawdown Date, assume that such Bank has made
available to the Agent on such Drawdown Date the amount of such Bank's
Commitment Percentage of the Syndicated Loans (or, in the case of Competitive
Bid Loans, the amount of such Bank's accepted offers of Competitive Bid Loans,
if any) to be made on such Drawdown Date, and the Agent may (but it shall not be
required to), in reliance upon such assumption, make available to the Borrower a
corresponding amount. If any Bank makes available to the Agent such amount on a
date after such Drawdown Date, such Bank shall pay to the Agent on demand an
amount equal to the product of (a) the average computed for the period referred
to in clause (c) below, of the weighted average interest rate paid by the Agent
for federal funds acquired by the Agent during each day included in such period,
TIMES (b) the amount of such Bank's Commitment Percentage of such Syndicated
Loans (or accepted offers of Competitive Bid Loans, as applicable), TIMES (c) a
fraction, the numerator of which is the number of days that elapse from and
including such Drawdown Date to the date on which the amount of such Bank's
Syndicated Loans or Competitive Bid Loans, as applicable, shall become
immediately available to the Agent, and the denominator of which is 365. A
statement of the Agent submitted to such Bank with respect to any amounts owing
under this ss.2.4.2 shall be PRIMA FACIE evidence of the amount due and owing to
the Agent by such Bank. If the amount of such Bank's Syndicated Loans or
Competitive Bid Loans, as applicable, is not made available to the Agent by such
Bank within three (3) Business Days following such Drawdown Date, the Agent
shall be entitled to recover such amount from the Borrower on demand, with
interest thereon at the rate per annum applicable to the Syndicated Loans or
Competitive Bid Loans, as applicable, made on such Drawdown Date and the
Borrower may take the actions permitted under ss.4.12 hereof to replace such
Bank. Any payment by the Borrower to the Agent of any Syndicated Loans or
Competitive Bid Loans pursuant to this ss.2.4.2 shall be deemed to be a payment
of the Loans that were to be made by the Bank that failed to make such
Syndicated Loans or Competitive Bid Loans, as applicable.

             ss.2.5. THE NOTES. (a) The Syndicated Loans shall be evidenced by
separate promissory notes of the Borrower in substantially the form of EXHIBIT
E-1 attached hereto (each a "Syndicated Note"), dated as of the Closing Date and
completed with appropriate insertions. A Syndicated Note shall be payable to 


<PAGE>   33


                                      -26-


the order of each Bank in a principal amount equal to such Bank's Commitment
Amount or, if less, the outstanding amount of all Syndicated Loans made by such
Bank, PLUS interest accrued thereon, as set forth below. The Borrower
irrevocably authorizes each Bank to make, at or about the time of the Drawdown
Date of any Syndicated Loan or at the time of receipt of any payment of
principal on such Bank's Syndicated Note, an appropriate notation on the Record
attached to such Bank's Syndicated Note reflecting the making of such Syndicated
Loan or (as the case may be) the receipt of such payment. The outstanding amount
of the Syndicated Loans set forth on such Bank's Record shall be PRIMA FACIE
evidence of the principal amount thereof owing and unpaid to such Bank, but the
failure to record, or any error in so recording, any such amount on such Bank's
Record shall not limit or otherwise affect the obligations of the Borrower
hereunder or under any Syndicated Note to make payments of principal of or
interest on any Syndicated Note when due.

             (b) The Competitive Bid Loans shall be evidenced by separate
promissory notes of the Borrower in substantially the form of EXHIBIT E-2
attached hereto (each a "Competitive Bid Note"), dated as of the Closing Date
and completed with appropriate insertions. A Competitive Bid Note shall be
payable to the order of each Bank in a principal amount equal to the Total
Commitment or, if less, the outstanding amount of all Competitive Bid Loans made
by such Bank to the Borrower hereunder, as set forth in ss.2.3 hereof, PLUS
interest accrued thereon, as set forth below. The Borrower irrevocably
authorizes each Bank to make, at or about the time of the Drawdown Date of any
Competitive Bid Loan made by such Bank or at the time of receipt of the payment
of principal of such Competitive Bid Loan, an appropriate notation on the Record
attached to such Bank's Competitive Bid Note reflecting the making of such
Competitive Bid Loan and repayments thereof. All such notations shall constitute
PRIMA FACIE evidence of the amount of such Competitive Bid Loans and the
repayments thereof, but the failure to record, or any error in so recording such
amount on such Bank's Record shall not limit or otherwise affect the obligations
of the Borrower hereunder or under any Competitive Bid Note to make payments of
principal or interest on any Competitive Bid Note when due.

             ss.2.6. REDUCTION OF TOTAL COMMITMENT. The Borrower shall have the
right at any time and from time to time prior to the Maturity Date upon three
(3) Business Days' prior written notice to the Agent to reduce by $5,000,000 or
an integral multiple thereof or terminate entirely the Total Commitment,
whereupon the Commitment Amount of each Bank shall be reduced PRO RATA in
accordance with its Commitment Percentage by the amount specified in such notice
or, as the case may be, terminated. Promptly after receiving any notice of the
Borrower delivered pursuant to this ss.2.6, the Agent will notify the Banks of
the substance thereof. Upon the effective date of any such reduction or
termination, the Borrower shall pay to the Agent for the respective accounts of


<PAGE>   34


                                      -27-


the Banks the full amount of the Facility Fee then accrued on the amount of the
reduction. No reduction or termination of the Total Commitment may be
reinstated.

             ss.2.7. MANDATORY REPAYMENTS OF REVOLVING CREDIT LOANS. If at any
time the sum, without duplication, of (A) the outstanding aggregate principal
amount of the Revolving Credit Loans PLUS (B) the outstanding aggregate
principal amount of Swing Line Loans PLUS (C) the Maximum Drawing Amount PLUS
(D) all Unpaid Reimbursement Obligations PLUS (E) the aggregate outstanding
principal amount of Competitive Bid Loans exceeds the Total Commitment, then the
Borrower shall immediately pay the amount of such excess to the Agent for
application to the Revolving Credit Loans or Unpaid Reimbursement Obligations
for the respective accounts of the Banks or to be held as cash collateral for
the Reimbursement Obligations. Each prepayment of Revolving Credit Loans shall
be allocated among the Banks, in proportion, as nearly as practicable to the
respective unpaid principal amount of each Bank's Syndicated Note, with
adjustments to the extent practicable to equalize any prior payments or
repayments not exactly in proportion, and if no Syndicated Loans are
outstanding, to the Competitive Bid Loans, in proportion, as nearly as
practicable, to the unpaid principal amount of each Bank's Competitive Bid Note.

             ss.2.8. OPTIONAL REPAYMENTS OF SYNDICATED LOANS. The Borrower shall
have the right, at its election, to repay the outstanding amount of the
Syndicated Loans, as a whole or in part, at any time without penalty or premium,
PROVIDED that any full or partial repayment of the outstanding amount of any
Eurodollar Rate Loans pursuant to this ss.2.8 may be made only on the last day
of the Interest Period relating thereto unless the Borrower pays each Bank, in
accordance with ss.4.10, the costs and expenses incurred by such Bank as a
result of the repayment of such Eurodollar Rate Loan on a day other than the
last day of the Interest Period relating thereto. The Borrower shall give the
Agent, prior written notice no later than 10:00 a. m., Boston time, on the date
of any proposed repayment pursuant to this ss.2.8 of Base Rate Loans, and three
(3) Eurodollar Business Days' notice of any proposed repayment pursuant to this
ss.2.8 of Eurodollar Rate Loans, in each case specifying the proposed date of
repayment of such Syndicated Loans and, the principal amount to be repaid. Each
such partial repayment of the Syndicated Loans shall be in an integral multiple
of $5,000,000, shall be accompanied by the payment of accrued interest on the
principal repaid to the date of repayment and shall be applied, in the absence
of instruction by the Borrower, first to the principal of Base Rate Loans and
then to the principal of Eurodollar Rate Loans. Each partial repayment shall be
allocated among the Banks, in proportion, as nearly as practicable, to the
respective unpaid principal amount of each Bank's applicable Syndicated 


<PAGE>   35


                                      -28-


Note being repaid, with adjustments to the extent practicable to equalize any
prior repayments not exactly in proportion.

             ss.2.9. INTEREST ON REVOLVING CREDIT LOANS. (a) During the Revolver
Period, except as otherwise provided in ss.4.11 hereof,

                    (i) each Base Rate Loan shall bear interest for the period
commencing with the Drawdown Date thereof and ending on the last day of the
Interest Period with respect thereto at the rate per annum equal to the Base
Rate;

                    (ii) each Eurodollar Rate Loan shall bear interest for the
period commencing with the Drawdown Date thereof and ending on the last day of
the Interest Period with respect thereto at the rate per annum equal to the
Eurodollar Rate determined for such Interest Period PLUS the Applicable Margin;
and

                    (iii) each Competitive Bid Loan shall bear interest at the
rate per annum specified in the applicable Competitive Bid Quote with respect to
such Competitive Bid Loan.

             (b) The Borrower promises to pay interest on each Revolving Credit
Loan in arrears on each Interest Payment Date applicable with respect thereto.

             ss.2.10. CONVERSION OPTIONS.

                    ss.2.10.1. CONVERSION TO DIFFERENT TYPE OF SYNDICATED LOAN.
The Borrower may elect from time to time to convert any outstanding Syndicated
Loan to a Syndicated Loan of another Type, PROVIDED that (a) with respect to any
such conversion of a Eurodollar Rate Loan to a Base Rate Loan, the Borrower
shall give the Agent at least one (1) Business Day's prior written notice of
such election; (b) with respect to any such conversion of a Base Rate Loan to a
Eurodollar Rate Loan, the Borrower shall give the Agent at least three (3)
Eurodollar Business Days' prior written notice of such election; (c) with
respect to any such conversion of a Eurodollar Rate Loan into a Base Rate Loan,
such conversion shall only be made on the last day of the Interest Period with
respect thereto; and (d) no Base Rate Loan may be converted into a Eurodollar
Rate Loan when any Default or Event of Default has occurred and is continuing.
On the date on which such conversion is being made each Bank shall take such
action as is necessary to transfer its Commitment Percentage of such Syndicated
Loans to its Domestic Lending Office or its Eurodollar Lending Office, as the
case may be. All or any part of outstanding Syndicated Loans of any Type may be
converted into a Syndicated Loan of another Type as provided herein, PROVIDED
that any partial conversion shall be in an aggregate principal amount


<PAGE>   36


                                      -29-


of $2,000,000 or a whole multiple of $1,000,000 in excess thereof. Each
Conversion Request relating to the conversion of a Syndicated Loan to a
Eurodollar Rate Loan shall be irrevocable by the Borrower.

                    ss.2.10.2. CONTINUATION OF TYPE OF SYNDICATED LOAN. Any
Syndicated Loan of any Type may be continued as a Syndicated Loan of the same
Type upon the expiration of an Interest Period with respect thereto by
compliance by the Borrower with the notice provisions contained in ss.2.10.1
hereof; PROVIDED that no Eurodollar Rate Loan may be continued as such when any
Default or Event of Default has occurred and is continuing, but shall be
automatically converted to a Base Rate Loan on the last day of the first
Interest Period relating thereto ending during the continuance of any Default or
Event of Default of which officers of the Agent active upon the Borrower's
account have actual knowledge. The Agent shall notify the Banks and the Borrower
promptly when any such automatic conversion contemplated by this ss.2.10.2 is
scheduled to occur.

                    ss.2.10.3. EURODOLLAR RATE LOANS. Any conversion to or from
Eurodollar Rate Loans shall be in such amounts and be made pursuant to such
elections so that, after giving effect thereto, the aggregate principal amount
of all Eurodollar Rate Loans having the same Interest Period shall not be less
than $2,000,000 or a whole multiple of $1,000,000 in excess thereof.

             ss.2.11. THE SWING LINE.

             (a) THE SWING LINE LOANS. Subject to the terms and conditions
hereinafter set forth, upon notice by the Borrower to the Agent in accordance
with this ss.2.11, the Agent agrees to make loans to the Borrower (the "Swing
Line Loans") on any Business Day prior to the Maturity Date in an aggregate
principal amount not to exceed $20,000,000 at any one time outstanding. Each
Swing Line Loan shall be in a minimum amount equal to $500,000 or an integral
multiple thereof. Notwithstanding any other provisions of this Credit Agreement
and in addition to the limit set forth above, at no time shall the aggregate
principal amount of all outstanding Swing Line Loans exceed the remainder of (i)
the Total Commitment then in effect MINUS (ii) the sum of, without duplication,
(A) the aggregate principal amount of all Syndicated Loans outstanding, PLUS (B)
the aggregate amount of Competitive Bid Loans outstanding at such time, PLUS (C)
the Maximum Drawing Amount, PLUS (D) all Unpaid Reimbursement Obligations.

             (b) NOTICE OF BORROWING. When the Borrower desires the Agent to
make a Swing Line Loan, it shall send to the Agent written notice in the form of
EXHIBIT I hereto (or telephonic notice confirmed in a writing in the form of
EXHIBIT I hereto) of each Swing Line Loan requested hereunder (a " Swing Line


<PAGE>   37


                                      -30-


Loan Request") not later than 2:00 p.m. (Boston time) on the proposed Drawdown
Date of any Swing Line Loan. Each such Swing Line Loan Request shall set forth
the principal amount of the proposed Swing Line Loan and the Swing Line Loan
Maturity Date relating to such Swing Line Loan, which shall in no event be later
than Maturity Date. Each Swing Line Loan Request shall be irrevocable and
binding on the Borrower and shall obligate the Borrower to borrow the Swing Line
Loan from the Agent on the proposed Drawdown Date thereof. Upon satisfaction of
the applicable conditions set forth in this Credit Agreement, on the proposed
Drawdown Date the Agent shall make the Swing Line Loan available to the Borrower
no later than 3:00 p.m. (Boston time) on the proposed Drawdown Date by crediting
the amount of the Swing Line Loan to the account specified by the Borrower;
PROVIDED that the Agent shall not advance any Swing Line Loans after it has
received notice from any Bank that a Default or Event of Default has occurred
and stating that no new Swing Line Loans are to be made until such Default or
Event of Default has been cured or waived in accordance with the provisions of
this Credit Agreement.

             (c) INTEREST ON SWING LINE LOANS. Each Swing Line Loan shall,
except as otherwise provided in ss.4.11 hereof, bear interest from the Drawdown
Date thereof until repaid in full at the rate per annum equal to the Money
Market Rate, which shall be paid on each Interest Payment Date for Base Rate
Loans. The Borrower may elect from time to time that a Swing Line Loan bear
interest at a fixed rate for a period of one week or such other period of time
as may be agreed to by the Agent, in which case, the interest rate on such Swing
Line Loan shall be the fixed rate of interest quoted by the Agent for such Swing
Line Loan for such Interest Period. The Borrower shall give the Agent notice no
later than 12:00 noon on the last day of the Interest Period relating to a Swing
Line Loan that is a Fixed Rate Loan of its intention to continue such Swing Line
Loan as a Fixed Rate Loan. In the event that the Borrower fails to give such
notice, such Swing Line Loan shall, on the last day of such Interest Period,
cease to be a Fixed Rate Loan.

             (d) REPAYMENT OF SWING LINE LOANS. The Borrower shall repay each
outstanding Swing Line Loan on or prior to the Swing Line Loan Maturity Date
relating thereto. Upon notice by the Agent on any Business Day following the
Swing Line Loan Maturity Date relating to each Swing Line Loan, in the event
that the Borrower has not repaid such Swing Line Loan, each of the Banks hereby
agrees to make Syndicated Loans to the Borrower constituting Base Rate Loans, on
the next succeeding Business Day following such notice, in an amount equal to
such Bank's Commitment Percentage of the aggregate amount of all Swing Line
Loans outstanding and overdue. The proceeds thereof shall be applied directly by
the Agent to repay outstanding Swing Line Loans. Each Bank hereby absolutely,
unconditionally and irrevocably agrees to make such Syndicated Loans upon one
Business Day's notice as set forth above,


<PAGE>   38


                                      -31-


notwithstanding (i) that the amount of such Syndicated Loan may not comply with
the applicable minimums set forth herein, (ii) the failure of the Borrower to
meet the applicable conditions set forth herein, (iii) the occurrence or
continuance of a Default or an Event of Default hereunder, and (iv) the Total
Commitment in effect at such time. In the event that it is impracticable for
such Syndicated Loan to be made for any reason on the date otherwise required
above, then each Bank hereby agrees that it shall forthwith purchase (as of the
date such Syndicated Loan would have been made, but adjusted for any payments
received from the Borrower on or after such date and prior to such purchase)
from the Agent, and the Agent shall sell to each Bank, such participations in
the Swing Line Loans (including all accrued and unpaid interest thereon)
outstanding as shall be necessary to cause the Banks to share in such Swing Line
Loans PRO RATA based on their respective Commitment Percentages (without regard
to any termination of the Total Commitment hereunder) by making available to the
Agent an amount equal to such Bank's participation in the Swing Line Loans;
PROVIDED that (x) all interest payable on the Swing Line Loans (other than
interest received by the Agent pursuant to clause (y)) shall be for the account
of the Agent as a funding and administrative fee until the date as of which the
respective participation is purchased, and (y) at the time any purchase of such
participation is actually made, the purchasing Bank shall be required to pay the
Agent interest on the principal amount of the participation so purchased for
each day from and including the date such Loan would otherwise have been made
until the date of payment for such participation at the rate of interest then
applicable to such Swing Line Loans during such period. The Borrower shall have
the right, at its election, to repay the outstanding amount of a Swing Line
Loan, as a whole or in part, at any time without penalty or premium, PROVIDED
that any full or partial repayment of the outstanding amount of any Swing Line
that is a Fixed Rate Loan may be made only on the last day of the Interest
Period relating thereto unless the Borrower pays, in accordance with ss.4.10,
the Agent the costs and expenses incurred by the Agent as a result of the
repayment of such Swing Line Loan on a day other than the last day of such
Interest Period relating thereto.

             (e) THE SWING LINE NOTE. The obligation of the Borrower to repay
the Swing Line Loans made pursuant to this Agreement and to pay interest thereon
as set forth in this Agreement shall be evidenced by a promissory note of the
Borrower substantially in the form of EXHIBIT E-3 attached hereto (the "Swing
Line Note"), dated the Closing Date and payable to the order of the Agent in a
principal amount stated to be the lesser of (i) $20,000,000 and (ii) the
aggregate principal amount of Swing Line Loans at any time advanced by the Agent
and outstanding hereunder. The Borrower irrevocably authorizes the Agent to make
or cause to be made, at or about the time of the Drawdown Date of any Swing Line
Loan or at the time of receipt of any payment of principal on the Swing Line
Note, an appropriate notation on the grid attached to such Note


<PAGE>   39


                                      -32-


or the Agent's records reflecting the making of such Swing Line Loan or (as the
case may be) the receipt of such payment. The outstanding amount of the Swing
Line Loans set forth on such grid or such records shall be PRIMA FACIE evidence
of the principal amount thereof owing and unpaid to the Agent, but the failure
to record, or any error in so recording, any such amount on such Note or such
records shall not limit or otherwise affect the actual amount of the obligations
of the Borrower hereunder or under the Swing Line Note to make payments of
principal of or interest on the Swing Line Note when due.

             ss.3. LETTERS OF CREDIT.

             ss.3.1. LETTERS OF CREDIT. Subject to the terms and conditions set
forth in this Credit Agreement, upon written request of the Borrower delivered
to the Letter of Credit Bank and upon the execution and delivery by the Borrower
of Reimbursement Agreements with the Letter of Credit Bank (with a copy to the
Agent), the Letter of Credit Bank shall issue, extend and renew at any time from
the Closing Date until the Maturity Date, and subject to the satisfaction of the
conditions precedent set forth in ss.ss.9 and 10 hereof, Letters of Credit in
such form as the Borrower and the Letter of Credit Bank may agree for the
account of the Borrower or any of its Subsidiaries, PROVIDED that at no time
shall the Maximum Drawing Amount of all Letters of Credit outstanding exceed
$50,000,000 or, if less, the Total Commitment, and PROVIDED FURTHER that at no
time shall the SUM of (a) the aggregate principal amount of all Syndicated Loans
outstanding, PLUS (b) the aggregate principal amount of all Swing Line Loans
outstanding, PLUS (c) the aggregate principal amount of all Competitive Bid
Loans outstanding, PLUS (d) the aggregate Maximum Drawing Amount of all Letters
of Credit outstanding and all Unpaid Reimbursement Obligations exceed the Total
Commitment then in effect. Each written request for the issuance of a Letter of
Credit hereunder shall be received by the Letter of Credit Bank at least ten
(10) Business Days prior to the proposed date of issuance, PROVIDED that the
Letter of Credit Bank shall use its best efforts to issue such Letter of Credit
within five (5) Business Days following its receipt of any written request
therefor. The expiry dates, amounts and beneficiaries of the Letters of Credit
will be as agreed by the Borrower and the Letter of Credit Bank in the
applicable Reimbursement Agreement. In the event of any conflict between the
terms of this Credit Agreement and such Reimbursement Agreement, the terms of
this Credit Agreement shall control. The Borrower may request, and the Letter of
Credit Bank upon terms and conditions approved by the Borrower shall issue,
substitute Letters of Credit for the Letters of Credit to reflect reductions in
the amount of the Borrower's obligations supported by such Letters of Credit.
Each Letter of Credit issued by the Letter of Credit Bank hereunder shall
identify: (i) the dates of issuance and expiry of such Letter of Credit, (ii)
the amount of such Letter of Credit (which shall be a sum certain), (iii) the
beneficiary and account party of such Letter of Credit, and (iv) the drafts and


<PAGE>   40


                                      -33-


other documents necessary to be presented to the issuing bank upon drawing
thereunder. Each Letter of Credit issued hereunder shall expire no later than
one year after its date of issuance unless renewed by the Letter of Credit Bank
in accordance with the terms of such Letter of Credit. In no event shall any
Letter of Credit issued hereunder expire after the date that is ten (10) days
prior to the Maturity Date. The Letter of Credit Bank shall notify the Agent on
the date of each issuance, amendment, extension, renewal or drawing of a Letter
of Credit, such notice to include details as to the expiration date, the face
amount of such Letter of Credit, the amount drawn under such Letter of Credit
and such other information as the Agent may reasonably request.

             ss.3.2. REIMBURSEMENT OBLIGATION OF THE BORROWER. If any draft
shall be presented or other demand for payment shall be made under any Letter of
Credit, the Letter of Credit Bank shall notify the Borrower of the date and
amount of the draft presented or demand for payment and of the date and time
when it expects to pay such draft or honor such demand for payment. Upon the
payment by the Letter of Credit Bank in respect of each drawing under a Letter
of Credit, the Borrower shall immediately pay the Letter of Credit Bank the
amount of such drawing (it being understood that the Borrower may, subject to
the conditions set forth herein, make such payment with the proceeds of a
Syndicated Loan requested pursuant to ss.2.2).

             ss.3.3. LETTER OF CREDIT LOAN OBLIGATIONS ABSOLUTE. (a) The
obligations of the Borrower to repay the Letter of Credit Bank and the Banks as
provided hereunder in respect of drawings under Letters of Credit shall rank
PARI PASSU with the obligations of the Borrower to repay the Loans hereunder,
and shall be absolute and unconditional under any and all circumstances. Without
limiting the generality of the foregoing, the Borrower's obligation to repay the
Borrower's obligations in respect of drawings under Letters of Credit, or any
renewals or extensions thereof, shall not be subject to any defense based on the
non-application or misapplication by the beneficiary of the proceeds of any such
payment or the legality, validity, regularity or enforceability of the Letter of
Credit, or any renewal or extension thereof, or any other document whatsoever.
Subject to the limitations of the following sentence, the Letter of Credit Bank
may accept or pay any draft presented to it under any Letter of Credit, or any
renewal or extension thereof, regardless of when drawn or made and whether or
not negotiated, if such draft, accompanying certificate or documents and any
transmittal advice are presented on or before the expiry date of the Letter of
Credit, or the renewal or extension thereof then in effect. Furthermore, neither
the Letter of Credit Bank nor any of its correspondents shall be responsible, as
to any document presented under a Letter of Credit or any renewal or extension
thereof which appears to be regular on its face, and appears on its face to
conform to the terms of the Letter of Credit and to make reasonable reference
thereto, for the validity or sufficiency of any signature or endorsement, for
delay 

<PAGE>   41


                                      -34-


in giving any notice or failure of any instrument to bear adequate reference to
the Letter of Credit or to any renewal or extension thereof, or failure of
documents not clearly specified in the Letter of Credit to accompany any
instrument at negotiation, or for failure of any person to note the amount of
any draft on the reverse of the Letter of Credit or on any renewal or extension
thereof.

             (b) The Letter of Credit Bank, upon receipt of any draft drawn
under a Letter of Credit, shall promptly examine such draft and any accompanying
certificate or other document in accordance with this ss.3 and with its
customary procedures for conformity to the requirements of such Letter of
Credit. Any action, inaction or omission on the part of the Letter of Credit
Bank or any of its correspondents under or in connection with any Letter of
Credit, or any renewal or extension thereof, or the related instruments,
documents or property, if in good faith and in conformity with such laws,
regulations or customs as are applicable and the terms of this ss.3.3, shall be
binding upon the Borrower and shall not place the Letter of Credit Bank or any
of its correspondents under any liability to the Borrower, in the absence of
gross negligence or willful misconduct by the Letter of Credit Bank or its
correspondents. The Letter of Credit Bank's rights, powers, privileges and
immunities specified in or arising under this Agreement are in addition to any
heretofore or at any time hereafter otherwise created or arising, whether by
statute or rule of law or contract. All Letters of Credit issued hereunder will,
except to the extent otherwise expressly provided hereunder, be governed by the
Uniform Customs and Practice for Documentary Credits (1993 Revision),
International Chamber of Commerce, Publication No. 500, and any subsequent
revisions thereof.

             ss.3.4. OBLIGATIONS OF THE BANKS. (a) Each Bank and the Borrower
hereby acknowledge that each Letter of Credit issued by the Letter of Credit
Bank pursuant to this Agreement is issued by the Letter of Credit Bank on behalf
of all of the Banks. In the event that the Letter of Credit Bank is not
reimbursed on the date of a drawing under a Letter of Credit, each Bank (other
than the Letter of Credit Bank) absolutely, unconditionally and irrevocably
agrees to reimburse the Letter of Credit Bank in an amount equal to such Bank's
Commitment Percentage of such Unpaid Reimbursement Obligation and to be
responsible for its Commitment Percentage of all liabilities incurred by the
Letter of Credit Bank in respect of each Letter of Credit opened or extended by
the Letter of Credit Bank for the account of the Borrower pursuant to this
Agreement. In the event that for any reason (including without limitation as a
result of the commencement of any proceedings under any bankruptcy,
reorganization, insolvency or other similar law with respect to the Borrower) it
is impracticable for any Bank to reimburse the Letter of Credit Bank in an
amount equal to such Bank's Commitment Percentage of any drawing under any
Letter of Credit, then each such Bank agrees that at the option of the Letter of


<PAGE>   42


                                      -35-


Credit Bank it shall purchase a participation in, or take an assignment from the
Letter of Credit Bank of, the Borrower's obligation to repay the Letter of
Credit Bank in respect of such drawing under such Letter of Credit in an amount
equal to such Bank's Commitment Percentage of such Unpaid Reimbursement
Obligation. The obligations of the Banks hereunder are several and the failure
of any Bank to fulfill its obligations shall not result in any Bank becoming
obligated to advance more than its Commitment Percentage of such Unpaid
Reimbursement Obligation.

             (b) Each Bank agrees with the Letter of Credit Bank and the other
Banks (other than the Letter of Credit Bank) that its obligations to provide to
the Letter of Credit Bank its Commitment Percentage of the amount of any Unpaid
Reimbursement Obligation shall be absolute, irrevocable and unconditional and
further agrees that such obligations shall not be affected in any way by any
intervening circumstances occurring before or after the making of such payment
by the Letter of Credit Bank pursuant to any Letter of Credit, including without
limitation:

                    (i) any modification or amendment of, or any consent,
               waiver, release or forbearance with respect to, any of the terms
               of this Credit Agreement or any other instrument or document
               referred to herein;

                    (ii) any other act or omission to act of any kind by the
               Letter of Credit Bank;

                    (iii) the existence of any Default or Event of Default; or

                    (iv) any change of any kind whatsoever in the financial
               position or creditworthiness of the Borrower or any of its
               Subsidiaries or any other Person.

             ss.3.5. LETTER OF CREDIT FEE. The Borrower shall pay to the Letter
of Credit Bank a fee (the "LETTER OF CREDIT FEE") for each Letter of Credit
issued or renewed by the Letter of Credit Bank at a rate per annum equal to (a)
with respect to each standby Letter of Credit, the Applicable Margin with
respect to Eurodollar Rate Loans in effect from time to time and (b) with
respect to documentary Letters of Credit, one-half (1/2) the Applicable Margin
with respect to Eurodollar Rate Loans in effect from time to time, in each case,
on the Maximum Drawing Amount of such Letter of Credit for the period such
Letter of Credit is outstanding. The Letter of Credit Bank shall, in turn, remit
to each Bank (including BKB) such Bank's Commitment Percentage of the Letter of
Credit Fee. In addition, the Borrower will pay the Letter of Credit Bank a
Fronting Fee (the "Fronting Fee") equal to one-tenth of one percent (0.10%) per
annum on the Maximum Drawing Amount of such Letter of Credit for the period 


<PAGE>   43


                                      -36-


such Letter of Credit is outstanding, which shall be retained by the Letter of
Credit Bank for its own account. The Letter of Credit Fee and the Fronting Fee
shall be payable quarterly in arrears on the last day of each calendar quarter.
In respect of each Letter of Credit, the Borrower shall also pay to the Letter
of Credit Bank, for its own account, the Letter of Credit Bank's customary
issuance, amendment, negotiation or document examination and other
administrative fees as in effect from time to time.

             ss.4. CERTAIN GENERAL PROVISIONS; FEES.

             ss.4.1. AGENT'S FEE. The Borrower shall pay to the Agent for the
Agent's own account, certain fees to the Agent (the "Agent's Fee") as provided
in a letter agreement dated November 13, 1997 (as such agreement may be amended
and in effect from time to time, the "Agent's Fee Letter") by and between the
Borrower and the Agent.

             ss.4.2. FACILITY FEE. During the Revolver Period, the Borrower
agrees to pay to the Agent for the accounts of the Banks in accordance with
their respective Commitment Percentages (except to the extent otherwise provided
below) a facility fee (the "Facility Fee"), which shall be calculated for each
day at a per annum rate as set forth in the definition of Applicable Margin with
respect to the Facility Fee in effect at such time on the Total Commitment. The
Facility Fee shall be payable quarterly in arrears on the last day of each
calendar quarter for the calendar quarter then ended commencing on the first
such date following the Closing Date, with a final payment on the Maturity Date
or any earlier date on which the Total Commitment shall terminate.

             ss.4.3. FUNDS FOR PAYMENTS.

                    ss.4.3.1. PAYMENTS TO AGENT. All payments of principal,
interest, Facility Fees, Letter of Credit Fees and any other amounts due
hereunder or under any of the other Loan Documents shall be made to the Agent,
for the respective accounts of the Banks and the Agent, at the Agent's Head
Office or at such other location in the Boston, Massachusetts, area that the
Agent may from time to time designate, in each case in immediately available
funds.

                    ss.4.3.2. NO OFFSET, ETC. All payments by the Borrower
hereunder and under any of the other Loan Documents shall be made without setoff
or counterclaim and free and clear of and without deduction for any taxes,
levies, imposts, duties, charges, fees, deductions, withholdings, compulsory
loans, restrictions or conditions of any nature now or hereafter imposed or
levied by any jurisdiction or any political subdivision thereof or taxing or
other authority therein unless the Borrower is compelled by law to make such
deduction or withholding. If any such obligation is imposed upon the Borrower
with respect


<PAGE>   44


                                      -37-


to any amount payable by it hereunder or under any of the other Loan Documents,
other than (a) with respect to taxes based upon the Agent's or any Bank's net
income, or (b) with respect to amounts owing to a Bank that (i) is not
incorporated under the laws of the United States of America or a state thereof
and (ii) has not delivered to the Agent the forms referred to in ss.4.3.3
hereof, the Borrower will pay to the Agent, for the account of the Banks or (as
the case may be) the Agent, on the date on which such amount is due and payable
hereunder or under such other Loan Document, such additional amount in Dollars
as shall be necessary to enable the Banks or the Agent to receive the same net
amount which the Banks or the Agent would have received on such due date had no
such obligation been imposed upon the Borrower. The Borrower will deliver
promptly to the Agent certificates or other valid vouchers for all taxes or
other charges deducted from or paid with respect to payments made by the
Borrower hereunder or under such other Loan Document.

                    ss.4.3.3. WITHHOLDING. Each Bank that is a party to this
Credit Agreement and that is not incorporated under the laws of the United
States of America or a state thereof agrees that it will deliver to the Agent,
within seven (7) Business Days of the Closing Date, or, in the case of a Bank
which becomes a Bank pursuant to an Assignment and Acceptance, on the date which
such Assignment and Acceptance becomes effective, a copy of United States
Internal Revenue Service form 1001 or 4224 (or other applicable form prescribed
by the United States Internal Revenue Service), in each case certifying that
such Bank is entitled to receive payments under this Credit Agreement and the
Notes without deduction or withholding of any United States federal income
taxes.

             ss.4.4. COMPUTATIONS. All computations of interest on Base Rate
Loans shall be based on a 365-day or 366-day year, as applicable, and all
computations of interest on Eurodollar Rate Loans, Competitive Bid Loans and of
Facility Fees, Letter of Credit Fees and other fees shall be based on a 360-day
year, and, in each case, paid for the actual number of days elapsed. Except as
otherwise provided in the definition of the term "Interest Period" with respect
to Eurodollar Rate Loans, whenever a payment hereunder or under any of the other
Loan Documents becomes due on a day that is not a Business Day, the due date for
such payment shall be extended to the next succeeding Business Day, and interest
shall accrue during such extension.

             ss.4.5. INABILITY TO DETERMINE EURODOLLAR RATE. In the event, prior
to the commencement of any Interest Period relating to any Eurodollar Rate Loan,
the Agent shall determine or be notified by the Majority Banks that adequate and
reasonable methods do not exist for ascertaining the Eurodollar Rate that would
otherwise determine the rate of interest to be applicable to any Eurodollar Rate
Loan during any Interest Period, the Agent shall forthwith give notice of such
determination (which shall be conclusive and binding on the 


<PAGE>   45


                                      -38-


Borrower and the Banks) to the Borrower and the Banks. In such event (a) any
Loan Request or Conversion Request with respect to Eurodollar Rate Loans shall
be automatically withdrawn and shall be deemed a request for Base Rate Loans,
(b) each Eurodollar Rate Loan will automatically, on the last day of the then
current Interest Period relating thereto, become a Base Rate Loan, and (c) the
obligations of the Banks to make Eurodollar Rate Loans shall be suspended until
the Agent or the Majority Banks, as applicable, determine that the circumstances
giving rise to such suspension no longer exist, whereupon the Agent or, as the
case may be, the Agent upon the instruction of the Majority Banks, shall so
notify the Borrower and the Banks.

             ss.4.6. ILLEGALITY. Notwithstanding any other provisions herein, if
any present or future law, regulation, treaty or directive or in the
interpretation or application thereof shall make it unlawful for any Bank to
make or maintain Eurodollar Rate Loans, such Bank shall forthwith give notice of
such circumstances to the Borrower and the other Banks and thereupon the
commitment of such Bank to make Eurodollar Rate Loans or convert Loans of
another Type to Eurodollar Rate Loans shall forthwith be suspended and such
Bank's Loans then outstanding as Eurodollar Rate Loans, if any, shall be
converted automatically to Base Rate Loans on the last day of each Interest
Period applicable to such Eurodollar Rate Loans or within such earlier period as
may be required by law. The Borrower hereby agrees promptly to pay the Agent for
the account of such Bank, upon demand by such Bank, any additional amounts
necessary to compensate such Bank for any costs incurred by such Bank in making
any conversion in accordance with this ss.4.6, including any interest or fees
payable by such Bank to lenders of funds obtained by it in order to make or
maintain its Eurodollar Loans hereunder.

             ss.4.7. ADDITIONAL COSTS, ETC. If any change after the Closing Date
to any present applicable law or if any future applicable law, which expression,
as used herein, includes statutes, rules and regulations thereunder and
interpretations thereof by any competent court or by any governmental or other
regulatory body or official charged with the administration or the
interpretation thereof and requests, directives, instructions and notices at any
time or from time to time hereafter made upon or otherwise issued to any Bank or
the Agent by any central bank or other fiscal, monetary or other authority
(whether or not having the force of law), shall:

             (a) subject any Bank or the Agent to any tax, levy, impost, duty,
charge, fee, deduction or withholding of any nature with respect to this Credit
Agreement, the other Loan Documents, such Bank's Commitment, the Loans or the
Letters of Credit (other than taxes based upon or measured by the income or
profits of such Bank or the Agent), or


<PAGE>   46


                                      -39-


             (b) materially change the basis of taxation (except for changes in
taxes on income or profits) of payments to any Bank of the principal of or the
interest on any Loans or any other amounts payable to any Bank or the Agent
under this Credit Agreement or any of the other Loan Documents, or

             (c) impose or increase or render applicable (other than to the
extent specifically provided for elsewhere in this Credit Agreement) any special
deposit, reserve, assessment, liquidity, capital adequacy or other similar
requirements (whether or not having the force of law) against assets held by, or
deposits in or for the account of, or loans by, or letters of credit issued by,
or commitments of an office of any Bank, or

             (d) impose on any Bank or the Agent any other conditions or
requirements with respect to this Credit Agreement, the other Loan Documents,
the Loans, the Letters of Credit such Bank's Commitment, or any class of loans,
letters of credit or commitments of which any of the Loans or such Bank's
Commitment forms a part,

and the result of any of the foregoing is:

                  (i) to increase the cost to any Bank of making, funding,
issuing, renewing, extending or maintaining any of the Loans, the Letters of
Credit or such Bank's Commitment, or

                  (ii) to reduce the amount of principal, interest, or other
amount payable to such Bank or the Agent hereunder on account of such Bank's
Commitment, or any of the Loans or Letters of Credit, or

                  (iii) to require such Bank or the Agent to make any payment or
to forego any interest or other sum payable hereunder, the amount of which
payment or foregone interest or other sum is calculated by reference to the
gross amount of any sum receivable or deemed received by such Bank or the Agent
from the Borrower hereunder,

then, in each such case and to the extent that the amount such additional cost,
reduction, payment, foregone interest or other sum is not reflected in the Base
Rate or the Eurodollar Rate, the Borrower will, upon demand made by such Bank or
(as the case may be) the Agent at any time and from time to time and as often as
the occasion therefor may arise, pay to such Bank or the Agent such additional
amounts as will be sufficient to compensate such Bank or the Agent for such
additional cost, reduction, payment or foregone interest or other sum (without
duplication for recovery of such amounts under any other provision hereof),
PROVIDED that the Borrower shall not be liable to any Bank or the Agent for
costs incurred more than sixty (60) days prior to receipt by the Borrower of


<PAGE>   47


                                      -40-


such demand for payment from such Bank or (as the case may be) the Agent unless
such costs were incurred prior to such 60-day period solely as a result of such
present or future applicable law being retroactive to a date which occurred
prior to such 60-day period.

             ss.4.8. CAPITAL ADEQUACY. If after the Closing Date any Bank or the
Agent determines that the adoption of or change in any law, governmental rule,
regulation, policy, guideline or directive (whether or not having the force of
law) regarding capital requirements for banks or bank holding companies or any
change in the interpretation or application thereof by a court or governmental
authority with appropriate jurisdiction has the effect of reducing the return on
such Bank's or the Agent's commitment with respect to any Loans or Letters of
Credit to a level below that which such Bank or the Agent could have achieved
but for such adoption, change or compliance (taking into consideration such
Bank's or the Agent's then existing policies with respect to capital adequacy
and assuming full utilization of such entity's capital) by any amount deemed by
such Bank or (as the case may be) the Agent to be material, then such Bank or
the Agent may notify the Borrower of such fact. To the extent that the amount of
such reduction in the return on capital is not reflected in the Base Rate or the
Eurodollar Rate then the Borrower agrees to pay such Bank or (as the case may
be) the Agent for the amount of such reduction in the return on capital as and
when such reduction is determined upon presentation by such Bank or (as the case
may be) the Agent of a certificate in accordance with ss.4.9 hereof, PROVIDED
that the Borrower shall not be liable to any Bank or the Agent for costs
incurred more than sixty (60) days prior to receipt by the Borrower of the
notice referred to in the immediately preceding sentence from such Bank or (as
the case may be) the Agent. Each Bank shall allocate such cost increases among
its customers in good faith and on an equitable basis.

             ss.4.9. CERTIFICATE. A certificate setting forth any additional
amounts payable pursuant to ss.ss.4.7 or 4.8 hereof and a brief explanation of
such amounts which are due, submitted by any Bank or the Agent to the Borrower,
shall be conclusive, absent manifest error, that such amounts are due and owing.
If the Borrower is required to pay any additional amounts pursuant to ss.ss.4.7
or 4.8 hereof with respect to any Bank, the Borrower may, following payment in
full of the amount or amounts due set forth in such certificate, take the
actions permitted by ss.4.12 hereof to replace such Bank.

             ss.4.10. INDEMNITY. The Borrower agrees to indemnify each Bank and
to hold each Bank harmless from and against all redeployment costs and expenses
that such Bank may sustain or incur as a consequence of (a) default by the
Borrower in payment of the principal amount of or any interest on any Eurodollar
Rate Loans, Competitive Bid Loans or Swing Line Loans which are Fixed Rate Loans
as and when due and payable, including any such cost or


<PAGE>   48


                                      -41-


expense arising from interest or fees payable by such Bank to lenders of funds
obtained by it in order to maintain its Eurodollar Rate Loans, Competitive Bid
Loans or such Swing Line Loans, (b) default by the Borrower in making a
borrowing or conversion after the Borrower has given (or is deemed to have
given) a Loan Request or a Conversion Request relating thereto in accordance
with ss.ss.2.2 or 2.10 hereof or a Notice of Competitive Bid Borrowing in
accordance with ss.2.3.1(f) hereof, or (c) the making of any payment of a
Eurodollar Rate Loan, Competitive Bid Loan or Swing Line Loan which is a Fixed
Rate Loan or the making of any conversion of any such Loan to a Base Rate Loan
on a day that is not the last day of the applicable Interest Period with respect
thereto, including interest or fees payable by such Bank to lenders of funds
obtained by it in order to maintain any such Loans.

             ss.4.11. INTEREST ON OVERDUE AMOUNTS. Overdue principal and (to the
extent permitted by applicable law) interest on the Loans and all other overdue
amounts payable hereunder or under any of the other Loan Documents, if not
repaid on or before the fifth calendar day following the day such payment was
due, shall bear interest from the due date thereof, compounded monthly and
payable on demand at any time from and after the fifth calendar day following
the day such payment was due, at a rate per annum equal to two percent (2%)
above the Base Rate until such amount shall be paid in full (after as well as
before judgment).

             ss.4.12. REPLACEMENT OF INDIVIDUAL BANKS. Upon the happening of any
of the events set forth in ss.ss.2.4.2, 4.6, 4.7, or 4.8, the Borrower may
(PROVIDED that at the time no Default or Event of Default exists or would result
after giving effect to the Borrower's action) prepay in full all Loans and other
obligations owing by the Borrower to each affected Bank (a "Substituted Bank"),
together with all amounts payable by the Borrower under ss.4.10 hereof with
respect to such prepayment, and terminate the Commitment(s) of such Bank(s)
subject to the following conditions:

                  (a) the Borrower shall have delivered to the Agent not less
than ten (10) Business Days prior to the exercise of its rights under this
ss.4.12 a written commitment in form and substance satisfactory to the Agent and
each of the Banks from a banking institution (the "Replacement Bank") reasonably
acceptable to the Agent and each of the remaining Banks (other than the
Substituted Bank) in which such Replacement Bank agrees to become a "Bank" under
this Credit Agreement, having a Commitment Amount in the amount of the
Substituted Bank's Commitment Amount;

                  (b) the Borrower shall have given appropriate notice of any
prepayment under this ss.4.12 as required by ss.2.8 and subject to all other
provisions of this Credit Agreement; and


<PAGE>   49


                                      -42-


                  (c) simultaneously with any prepayment of all Syndicated Loans
and other obligations owing by the Borrower to a Substituted Bank under this
ss.4.12, the Substituted Bank shall have assigned pursuant to ss.17 hereof of
this Credit Agreement the Commitment of such Substituted Bank to the Replacement
Bank and such Replacement Bank shall have become a Bank under this Credit
Agreement, having a Commitment Amount in the amount of such Substituted Bank's
Commitment Amount and such Replacement Bank shall have simultaneously funded all
such Loans prepaid hereunder.

             ss.4.13. GUARANTIES. The payment and performance of the Obligations
shall be guaranteed by each Guarantor pursuant to the Guaranties, each of which
shall be in the form of EXHIBIT F hereto. The Agent and the Banks hereby agree
that they shall, upon the written request of the Borrower and at the cost and
expense of the Borrower, release any Guarantor from its obligations to the Agent
and the Banks under the Guaranty to which such Guarantor is a party if, and only
if, (a) such Guarantor is no longer a Subsidiary of the Borrower, (b) no Default
or Event of Default shall have occurred and be continuing on the date of such
release, and (c) the Borrower shall have delivered to the Agent and the Banks on
the date of such release a certificate signed by an authorized officer of the
Borrower and evidence satisfactory to the Agent and the Banks showing compliance
with the provisions of clauses (a) and (b) hereof. The Borrower shall deliver to
the Banks an updated SCHEDULE 2 upon the release or addition of any Guarantor of
its obligations as provided in this ss.4.13.

             ss.5. REPRESENTATIONS AND WARRANTIES. The Borrower represents and

business substantially as now conducted by it, or result in any substantial
liability not adequately covered by insurance, or for which adequate reserves
are not maintained on the consolidated balance sheet of the Borrower and its
Subsidiaries or which question the validity of this Credit Agreement or any of
the other Loan Documents, or any action taken or to be taken pursuant hereto or
thereto.

             ss.5.8. COMPLIANCE WITH OTHER INSTRUMENTS, LAWS, ETC. Neither the

        ss.5.12. EMPLOYEE BENEFIT PLANS.

                ss.5.12.1. IN GENERAL. Each Employee Benefit Plan has been
maintained and operated in compliance in all material respects with the
provisions of ERISA and, to the extent applicable, the Code, including but not
limited to the provisions thereunder respecting prohibited transactions.

                ss.5.12.2. TERMINABILITY OF WELFARE PLANS. Under each Employee
Benefit Plan which is an employee welfare benefit plan within the meaning of
ss.3(1) or ss.3(2)(B) of ERISA, no benefits are due unless The event giving rise
to the benefit entitlement occurs prior to plan termination (except as required
by Title I, Part 6 of ERISA). The Borrower or an ERISA Affiliate, as
appropriate, may terminate each such Plan at any time (or at any time subsequent
to the expiration of any applicable bargaining agreement) in the discretion of
the Borrower or such ERISA Affiliate without liability to any Person.

                ss.5.12.3. GUARANTEED PENSION PLANS. Each contribution required
to be made to a guaranteed pension plan, whether required to be made to avoid
the incurrence of an accumulated funding deficiency, the notice or lien
provisions of ss.302(f) of ERISA, or otherwise, has been timely made. No waiver
of an accumulated funding deficiency or extension of amortization periods has
been received with respect to any Guaranteed Pension Plan. No liability to the
PBGC (other than required insurance premiums, all of which have been paid) has
been incurred by the Borrower or any ERISA Affiliate with respect to any
Guaranteed Pension Plan and there has not been any ERISA Reportable Event, or
any other event or condition which presents a material risk of termination of
any Guaranteed Pension Plan by the PBGC. Based on the latest valuation of each
Guaranteed Pension Plan (which in each case occurred within twelve months of the
date of this representation), and on the actuarial methods and assumptions
employed for that valuation, except as set forth on SCHEDULE 5.12 attached
hereto, the aggregate benefit liabilities of all such Guaranteed Pension Plans
within the meaning of ss.4001 of ERISA did not exceed the aggregate value of the
assets of all such Guaranteed Pension Plans, disregarding for this purpose the
benefit liabilities and assets of any Guaranteed Pension Plan with assets in
excess of benefit liabilities.

                ss.5.12.4. MULTIEMPLOYER PLANS. Neither the Borrower nor any
ERISA Affiliate has incurred any material liability (including secondary
liability) to any Multiemployer Plan as a result of a complete or partial
withdrawal from such Multiemployer Plan under ss.4201 of ERISA or as a result of
a sale of assets described in ss.4204 of ERISA. Neither the Borrower nor any
ERISA Affiliate has been notified that any Multiemployer Plan is in
reorganization or insolvent under and within the meaning of ss.4241 or ss.4245
of 


<PAGE>   54
                                      -47-


ERISA or that any multiemployer Plan intends to terminate or has been terminated
under ss.4041A of ERISA.

        ss.5.13. REGULATIONS U AND X; ETC. The proceeds of the Loans and the
Letters of Credit shall be used for the purposes described in ss.6.12 hereof. No
portion of any Loan or any Letter of Credit is to be used for the purpose of
purchasing or carrying any "margin security" or "margin stock" (as such terms
are used in Regulations U and X of the Board of Governors of the Federal Reserve
System, 12 C.F.R. Parts 221 and 224 (the "Margin Regulations")) in violation of
the Margin Regulations.

        ss.5.14. ENVIRONMENTAL COMPLIANCE. The Borrower has taken all reasonably
necessary steps to investigate the past and present condition and usage of the

investigation, has determined that:

                (a)     none of the Borrower, its Subsidiaries nor any operator
of the Real Estate or any operations thereon is in violation, or alleged
violation, of any Environmental Laws, which violation would have a material
adverse effect on the business, assets or financial condition of the Borrower
and its Subsidiaries taken as a whole;

                (b)     neither the Borrower nor any of its Subsidiaries has

forth on SCHEDULE 5.14 hereto;,

                (c)     except as set forth on SCHEDULE 5.14 attached hereto:
(i) no portion of the Real Estate has been used for the handling, processing,
storage or disposal of Hazardous Substances; and no underground tank or other
underground storage receptacle for Hazardous Substances is located on any
portion of the Real Estate; in each case except in accordance with applicable
Environmental Laws the noncompliance with which would have a material adverse
effect on the business, assets or financial condition of the Borrower and its
Subsidiaries, taken as a whole; (ii) in the course of any activities conducted
by the Borrower or operators of its properties, no Hazardous Substances have
been generated or are being used on the Real Estate except in accordance with

and its Subsidiaries, taken as a whole; (iii) there have been no releases or
threatened releases of Hazardous Substances on, upon, into or from the

the Borrower and its Subsidiaries, taken as a whole; (iv) to the best of the
Borrower's knowledge, there have been no releases on, upon, from or into any

groundwater contamination, may have come to be located on the Real Estate and

primarily in the businesses now conducted by them and in related businesses;
PROVIDED that nothing in this ss.6.6 shall prevent the Borrower from
discontinuing the operation and maintenance of any of its properties or any of

Subsidiaries on a consolidated basis.

        ss.6.7. INSURANCE. The Borrower will, and will cause each of its
Subsidiaries to, maintain with financially sound and reputable insurers

assets or financial condition of the Borrower and its Subsidiaries, taken as a
whole, or on the ability of the Borrower or any of the Guarantors to fulfill its
obligations under this Credit Agreement or any of the other Loan Documents to

obligations hereunder or any of the other Loan Documents to which the Borrower
is a party, the Borrower will, or (as the case may be) will cause such
Subsidiary to, immediately take or cause to be taken all reasonable steps within

expected to result in liability of the Borrower or any of its Subsidiaries to

purposes of this subsection (m) shall mean the occurrence of any of the
following events):

                        (i)     the acquisition by any Person (including any

transaction or series 



<PAGE>   76

                                      -69-


of transactions, of shares of Capital Stock of the Borrower entitling such
Person to exercise 50% or more of the total voting power of all shares of
Capital Stock of the Borrower entitled to vote generally in the elections of
directors (any shares of voting stock of which such person or group is the
beneficial owner that are not then outstanding being deemed outstanding for
purposes of calculating such percentage);

                        (ii)    any consolidation of the Borrower with, or
merger of the Borrower into, any other Person, any merger of another Person into
the Borrower, or any sale or transfer of all or substantially all of the assets
of the Borrower to another Person (other than a transfer of assets to one or
more Guarantors or a merger (A) which does not result in any reclassification,
conversion, exchange or cancellation of outstanding shares of Capital Stock of
the Borrower or (B) which is effected solely to change the jurisdiction of
incorporation of the Borrower); or

                        (iii)   during any consecutive two-year period,
individuals who at the beginning of such period constituted the Board of
Directors of the Borrower (together with any new directors whose election by
such Board of Directors or whose nomination for election by the stockholders of
the Borrower was approved by a vote of 66-2/3% of the directors then still in
office who were either directors at the beginning of such period or whose
election or nomination for election was previously so approved) cease for any
reason to constitute a majority of the Board of Directors of the Borrower then
in office;

then, and in any such event, so long as the same may be continuing, the Agent
may, and upon the request of the Majority Banks shall, by notice in writing to
the Borrower declare all amounts owing with respect to this Credit Agreement,
the Notes, the Letters of Credit and the other Loan Documents and all
Reimbursement Obligations to be, and they shall thereupon forthwith become,
immediately due and payable without presentment, demand, protest or other notice
of any kind, all of which are hereby expressly waived by the Borrower; PROVIDED
that in the event of any Event of Default specified in secs.11.1(g) or 11.1(h)
hereof, all such amounts shall become immediately due and payable automatically
and without any requirement of notice from the Agent or any Bank.

        SS.11.2. TERMINATION OF COMMITMENTS. If any one or more of the Events of
Default specified in secs.11.1(g) or 11.1(h) hereof shall occur, any unused
portion of the credit hereunder shall forthwith terminate and each of the Banks
shall be relieved of all further obligations to make Loans to the Borrower and
the Letter of Credit Bank shall be relieved of all further obligations to issue
Letters of Credit. If any other Event of Default shall have occurred and be
continuing, the Agent may and, upon the request of the Majority Banks, shall, by
notice to the 




<PAGE>   77

                                      -70-



Borrower, terminate the unused portion of the credit hereunder, and upon such
notice being given such unused portion of the credit hereunder shall terminate
immediately and each of the Banks shall be relieved of all further obligations
to make Loans and the Letter of Credit Bank shall be relieved of all further
obligations to issue Letters of Credit. In the event of any termination of the
Commitments hereunder, the Borrower shall immediately deposit with the Agent
cash collateral in an amount equal to the Maximum Drawing Amount, pursuant to a
cash collateral agreement as shall be in form and substance satisfactory to the
Agent. No termination of the credit hereunder shall relieve the Borrower of any
of the Obligations.

        SS.11.3. REMEDIES. In case any one or more of the Events of Default
shall have occurred and be continuing, and whether or not the Banks shall have
accelerated the maturity of the Loans pursuant to ss.11.1 hereof, each Bank, if
owed any amount with respect to the Loans or Letters of Credit and upon the
consent of the Majority Banks, may proceed to protect and enforce its rights by
suit in equity, action at law or other appropriate proceeding, whether for the
specific performance of any covenant or agreement contained in this Credit
Agreement and the other Loan Documents or any instrument pursuant to which the
Obligations to such Bank are evidenced, including as permitted by applicable law
the obtaining of the EX PARTE appointment of a receiver, and, if such amount
shall have become due, by declaration or otherwise, proceed to enforce the
payment thereof or any other legal or equitable right of such Bank. No remedy
herein conferred upon any Bank or the Agent or the holder of any Note is
intended to be exclusive of any other remedy and each and every remedy shall be
cumulative and shall be in addition to every other remedy given hereunder or now
or hereafter existing at law or in equity or by statute or any other provision
of law.

        SS.12.  SETOFF. Regardless of the adequacy of any collateral, during the
continuance of any Event of Default, any deposits or other sums credited by or
due from any of the Banks to the Borrower and any securities or other property
of the Borrower in the possession of such Bank may be applied to or set off by
such Bank against the payment of Obligations and any and all other liabilities,
direct, or indirect, absolute or contingent, due or to become due, now existing
or hereafter arising, of the Borrower to such Bank. Each of the Banks agrees
with each other Bank that (a) if an amount to be set off is to be applied to
Indebtedness of the Borrower to such Bank, other than Indebtedness evidenced by
the Notes held by such Bank, such amount shall be applied ratably to such other
Indebtedness (except that no amounts shall be applied to documentary letters of
credit) and to the Indebtedness evidenced by all such Notes held by such Bank,
and (b) if such Bank shall receive from the Borrower, whether by voluntary
payment, exercise of the right of setoff, counterclaim, cross action,
enforcement of the claim evidenced by the Notes held by such Bank by 




<PAGE>   78

                                      -71-



proceedings against the Borrower at law or in equity or by proof thereof in
bankruptcy, reorganization, liquidation, receivership or similar proceedings, or
otherwise, and shall retain and apply to the payment of the Note or Notes held
by such Bank any amount in excess of its ratable portion of the payments
received by all of the Banks with respect to the Syndicated Notes held by all of
the Banks, such Bank will make such disposition and arrangements with the other
Banks with respect to such excess, either by way of distribution, PRO TANTO
assignment of claims, subrogation or otherwise as shall result in each Bank
receiving in respect of the Syndicated Notes held by it, its proportionate
payment as contemplated by this Credit Agreement; PROVIDED that if all or any
part of such excess payment is thereafter recovered from such Bank, such
disposition and arrangements shall be rescinded and the amount restored to the
extent of such recovery, but without interest.

        SS.13.  THE AGENT.

        SS.13.1. AUTHORIZATION.

        (a)     The Agent is authorized to take such action on behalf of each of
the Banks and to exercise all such powers as are hereunder and under any of the
other Loan Documents and any related documents delegated to the Agent, together
with such powers as are reasonably incident thereto, PROVIDED that no duties or
responsibilities not expressly assumed herein or therein shall be implied to
have been assumed by the Agent.

        (b)     The relationship between the Agent and the Banks is and shall be
that of an independent contractor. The use of the term "Agent" herein is for
convenience only and is used to describe, as a form of convention, the
independent contractual relationship between the Agent and each of the Banks.
Nothing contained in this Agreement or any of the other Loan Documents shall be
construed to create an agency, trust or other fiduciary relationship between the
Agent and any of the Banks.

        (c)     As an independent contractor empowered by the Banks to exercise
certain rights and perform certain duties and responsibilities hereunder and
under the other Loan Documents, the Agent is nevertheless a "representative" of
the Banks, as that term is defined in Article 1 of the Uniform Commercial Code,
for purposes of actions for the benefit of the Banks with respect to all
collateral security and guaranties contemplated by the Loan Documents. Such
actions include the designation of the Agent as "secured party", "mortgagee",
"lienholder" or the like on all financing statements, motor vehicle titles and
other documents and instruments, whether recorded or otherwise, relating to the
attachment, perfection, priority or enforcement of any security interests,
mortgages, liens or deeds of trust in collateral security intended to secure the





<PAGE>   79

                                      -72-



payment or performance of any of the Obligations, all for the benefit of the
Banks and the Agent.

        SS.13.2. EMPLOYEES AND AGENTS. The Agent may exercise its powers and
execute its duties by or through employees or agents and shall be entitled to
take, and to rely on, advice of counsel concerning all matters pertaining to its
rights and duties under this Credit Agreement and the other Loan Documents. The
Agent may utilize the services of such Persons as the Agent in its sole
discretion may reasonably determine, and all reasonable fees and expenses of any
such Persons shall be paid by the Borrower.

        SS.13.3. NO LIABILITY. Neither the Agent nor any of its shareholders,
directors, officers or employees nor any other Person assisting them in their
duties nor any agent or employee thereof, shall be liable to the Banks for any
waiver, consent or approval given or any action taken, or omitted to be taken,
in good faith by it or them hereunder or under any of the other Loan Documents,
or in connection herewith or therewith, or be responsible for the consequences
of any oversight or error of judgment whatsoever, except that the Agent or such
other Person, as the case may be, may be liable for losses due to its willful
misconduct or gross negligence.

        SS.13.4. NO REPRESENTATIONS. The Agent shall not be responsible for the
execution or validity or enforceability of this Credit Agreement, the Notes, the
Letters of Credit, any of the other Loan Documents or any instrument at any time
constituting, or intended to constitute, collateral security for the Notes, or
for the value of any such collateral security or for the validity,
enforceability or collectability of any such amounts owing with respect to the
Notes, or for any recitals or statements, warranties or representations made
herein or in any of the other Loan Documents or in any certificate or instrument
hereafter furnished to it by or on behalf of the Borrower or any of its
Subsidiaries, or be bound to ascertain or inquire as to the performance or
observance of any of the terms, conditions, covenants or agreements herein or in
any instrument at any time constituting, or intended to constitute, collateral
security for the Notes or to inspect any of the properties, books or records of
the Borrower or any of its Subsidiaries. The Agent shall not be bound to
ascertain whether any notice, consent, waiver or request delivered to it by the
Borrower or any holder of any of the Notes shall have been duly authorized or is
true, accurate and complete. The Agent has not made nor does it now make any
representations or warranties, express or implied, nor does it assume any
liability to the Banks, with respect to the creditworthiness or financial
conditions of the Borrower or any of its Subsidiaries. Each Bank acknowledges
that it has, independently and without reliance upon the Agent or any other
Bank, and based upon such information and documents as it has deemed
appropriate, made its own credit analysis and decision to enter into this Credit
Agreement.

                                      -73-


        SS.13.5. PAYMENTS.

                SS.13.5.1. PAYMENTS TO AGENT. A payment by the Borrower to the
Agent hereunder or any of the other Loan Documents for the account of any Bank
shall constitute a payment to such Bank. The Agent agrees promptly to distribute
to each Bank such Bank's PRO RATA share of payments received by the Agent for
the account of the Banks except as otherwise expressly provided herein or in any
of the other Loan Documents.

                SS.13.5.2. DISTRIBUTION BY AGENT. If in the opinion of the Agent
the distribution of any amount received by it in such capacity hereunder, under
the Notes or under any of the other Loan Documents might involve it in
liability, it may refrain from making distribution until its right to make
distribution shall have been adjudicated by a court of competent jurisdiction.
If a court of competent jurisdiction shall adjudge that any amount received and
distributed by the Agent is to be repaid, each Person to whom any such
distribution shall have been made shall either repay to the Agent its
proportionate share of the amount so adjudged to be repaid or shall pay over the
same in such manner and to such Persons as shall be determined by such court.

                SS.13.5.3. DELINQUENT BANKS. Notwithstanding anything to the
contrary contained in this Credit Agreement or any of the other Loan Documents,
any Bank that fails (a) to make available to the Agent its PRO RATA share of any
Loan or fails to make available to the Letter of Credit Bank its PRO RATA share
of each drawing under any Letter of Credit or (b) to comply with the provisions
of ss.12 hereof with respect to making dispositions and arrangements with the
other Banks, where such Bank's share of any payment received, whether by setoff
or otherwise, is in excess of its PRO RATA share of such payments due and
payable to all of the Banks, in each case as, when and to the full extent
required by the provisions of this Credit Agreement, shall be deemed delinquent
(a "Delinquent Bank") and shall be deemed a Delinquent Bank until such time as
such delinquency is satisfied. A Delinquent Bank shall be deemed to have
assigned any and all payments due to it from the Borrower, whether on account of
outstanding Loans, interest, fees or otherwise, to the remaining nondelinquent
Banks for application to, and reduction of, their respective PRO RATA shares of
all outstanding Syndicated Loans. The Delinquent Bank hereby authorizes the
Agent to distribute such payments to the nondelinquent Banks in proportion to
their respective PRO RATA shares of all outstanding Syndicated Loans. A
Delinquent Bank shall be deemed to have satisfied in full a delinquency when and
if, as a result of application of the assigned payments to all outstanding
Syndicated Loans of the nondelinquent Banks, the Banks' respective PRO RATA
shares of all outstanding Syndicated Loans have returned to

to the nonpayment causing such delinquency.

Note as the absolute owner or purchaser thereof for all purposes hereof until it
shall have been furnished in writing with a different name by such payee or by a
subsequent holder, assignee or transferee.

        SS.13.7. INDEMNITY. The Banks ratably agree hereby to indemnify and hold
harmless the Agent from and against any and all claims, actions and suits
(whether groundless or otherwise), losses, damages, costs, expenses (including
any expenses for which the Agent has not been reimbursed by the Borrower as
required by ss.14 hereof), and liabilities of every nature and character arising
out of or related to this Credit Agreement, the Notes, the Letters of Credit, or
any of the other Loan Documents or the transactions contemplated or evidenced
hereby or thereby, or the Agent's actions taken hereunder or thereunder, except
to the extent that any of the same shall be directly caused by the Agent's
willful misconduct or gross negligence.

        SS.13.8. AGENT AS BANK; ETC. In its individual capacity, BKB shall have
the same obligations and the same rights, powers and privileges in respect to
its Commitment and the Loans made by it, and as the holder of any of the Notes,
as it would have were it not also the Agent. None of the Documentation Agent,
the Syndication Agent or any Co-Agent shall have any obligation, liability,
responsibility or duty under this Credit Agreement other than as a Bank
hereunder.

        SS.13.9. RESIGNATION. The Agent may resign at any time by giving sixty
(60) days' prior written notice thereof to the Banks and the Borrower. Upon any
such resignation, the Majority Banks shall have the right to appoint a successor
Agent. Unless a Default or Event of Default shall have occurred and be
continuing, such successor Agent shall be reasonably acceptable to the Borrower.
If no successor Agent shall have been so appointed by the Majority Banks and
shall have accepted such appointment within thirty (30) days after the retiring
Agent's giving of notice of resignation, then the retiring Agent may, on behalf
of the Banks, appoint a successor Agent reasonably acceptable to the Borrower,
which shall be a financial institution having a rating of not less than A or its
equivalent by S&P. Upon the acceptance of any appointment as Agent hereunder by
a successor Agent, such successor Agent shall thereupon succeed to and become
vested with all the rights, powers, privileges and duties of the retiring Agent,
and the retiring Agent shall be discharged from its duties and obligations
hereunder. After any retiring Agent's resignation, the provisions of this Credit
Agreement and the other Loan Documents shall continue in effect for

it was acting as Agent.
