             NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
                                  (Unaudited)


Johns Manville International Group, Inc. (the "Company"), is a wholly owned
subsidiary of Johns Manville Corporation. The condensed consolidated financial
statements as of June 30, 1998 and December 31, 1997 and for the three and six
months ended June 30, 1998 and 1997 reflect all normal, recurring adjustments
which are, in the opinion of management, necessary for a fair presentation of
the financial condition and the results of operations for the periods presented.
The year-end condensed consolidated balance sheet was derived from audited
financial statements, and as presented does not include all disclosures required
by generally accepted accounting principles. The Company has reclassified the
presentation of certain prior period information to conform with the current
presentation format. Additional information regarding the Company's accounting
policies, operations and financial position is contained or incorporated in the
Company's Form 10-K for the year ended December 31, 1997 filed with the
Securities and Exchange Commission.

Note 2 - Debt

In May 1998, the Company consummated a cash tender offer for substantially all
of its $400 million of 10 7/8% Senior Notes due 2004 (the "Senior Notes").  This
transaction resulted in an extraordinary loss on the early extinguishment of
debt of $30.1 million, net of taxes of $19.8 million, in the second quarter of
1998.  In conjunction with the tender offer, the Company arranged unsecured
multicurrency revolving credit facilities (the "credit facilities") totaling
approximately $750 million at a floating interest rate of LIBOR plus an
additional margin, with an initial termination date of May 15, 2003.  The
Company used $450 million of the credit facilities to repurchase the Senior
Notes. At June 30, 1998, $411 million of borrowings under the credit facilities
were outstanding. The remaining credit facilities are available for funding
acquisitions and capital expenditures, and other corporate purposes. The Company
also canceled its $100 million receivables sale facility and its $75 million
revolving line of credit available to international subsidiaries.

In order to fix a portion of the Company's variable interest rate debt and
reduce the aggregate risk to movements in interest rates, the Company entered
into interest rate swap transactions with notional values totaling approximately
$178 million. In addition to reducing risk, the interest rate swaps have a
correlation to the 

                                      I-5
<PAGE>
 
underlying debt obligation, and therefore, qualify for hedge accounting. Related
amounts payable or receivable are accrued on a current basis as adjustments to
interest expense. Any gains (losses) on the termination of the interest rate
swaps are deferred and recognized over periods corresponding to the related 
obligation being hedged. The Company does not use derivative instruments for
trading purposes. As of June 30, 1998, there were no material impacts on the
Company's financial condition, liquidity or results of operations due to the
interest rate swap transactions.

Note 3 - Cumulative Effect of Accounting Change

Effective January 1, 1998, the Company changed its method of accounting for
glass furnace rebuild costs to the capitalization method from the allowance
method.  Under the capitalization method, costs to periodically rebuild the
refractory components of the glass furnaces are capitalized when incurred and
depreciated on a straight-line basis over the estimated useful life of the
rebuild.  The capitalization method provides an improved measure of the
Company's capital investment and is consistent with industry practice.
Previously, estimated costs to rebuild furnaces were credited to an allowance
and charged to operations over the estimated period to the next rebuild date.
The cumulative effect of this change in accounting principle increases 1998
earnings by $27.4 million, net of taxes of $17.9 million.  This change resulted
in an increase in depreciation expense but eliminated the provision for furnace
rebuilds.  The pro forma effect of this change on net income was not material.

Note 4 - Comprehensive Income

Effective January 1, 1998, the Company adopted Statement of Financial Accounting
Standards No. 130, "Reporting Comprehensive Income."  Comprehensive income
generally includes changes in separately reported components of equity along
with net income. The Company's comprehensive income for 1998 and 1997 includes
net income as reported and foreign currency translation adjustments.

Note 5 - Acquisitions

In January 1998, the Company acquired the assets of a U.S. manufacturer of
reinforced thermoplastic roofing systems and also acquired a plant associated
with the Insulation segment, which manufactures calcium silicate pipe and block
insulation, and fireproof board. In May 1998, the Company acquired Exeltherm, a
Canadian producer of polyisocyanurate foam products for commercial/industrial
roofing and residential construction.  Also in May 1998, the Company acquired
Skandinaviska Jute, which owns Tasso AB, a European manufacturer of fiber glass
wall coverings.  This acquisition is associated with businesses of the
Engineered Products segment.

The combined purchase price for these acquisitions, accounted for under the
purchase method, was $55 million which was financed from existing cash balances.
The excess of the combined purchase prices over the estimated fair value of net
assets acquired, or goodwill, amounted to approximately $30 million.

Note 6 - New Accounting Pronouncements

In February 1998, the Financial Accounting Standards Board issued Statement of
Financial Accounting Standards No. 132, "Employers' Disclosures about Pensions
and Other Postretirement Benefits."  This statement, effective for periods
beginning after December 15, 1997, revises the required disclosures for employee
benefit plans, but does not change the measurement or recognition of such plans.

In June 1998, the Financial Accounting Standards Board issued Statement of
Financial Accounting Standards No. 133, "Accounting for Derivative Instruments
and Hedging Activities."  This statement, effective for all fiscal quarters of
fiscal years beginning after June 15, 1999, establishes accounting and reporting
standards for derivative instruments and for hedging activities.  It requires
that the Company recognize all derivatives as either assets or liabilities in
the statement of financial position and measure those instruments at fair value.
At this time, the Company cannot determine the effects, if any, adopting this
statement will have on its financial condition, liquidity or results of
operations.

Note 7 - Business Segment Information

The Company reports separately the results of the Insulation, Roofing Systems
and Engineered Products segments.  The Insulation segment consists of the
Company's building, commercial/industrial and original equipment manufacturers
("OEM") insulation businesses.  The Roofing Systems segment consists of the
Company's commercial/industrial roofing systems business.  The Engineered
Products segment consists of the Company's mats and fibers and filtration
businesses.  Effective January 1, 1998, the Company adopted Statement of
Financial Accounting Standards No. 131, "Disclosures about Segments of an
Enterprise and Related Information." Consistent with the Company's internal
reporting, business segments now include allocated corporate expenses.  The 1997
results were reclassified to conform with the current presentation format.

ITEM 2.

                    JOHNS MANVILLE INTERNATIONAL GROUP, INC.
               MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL
                      CONDITION AND RESULTS OF OPERATIONS

RESULTS OF OPERATIONS

The Company's net sales in the second quarter of 1998 increased $17.2 million,
or 4 percent, to $445.2 million compared with $428 million for the same period
of 1997. Gross profit increased $1.9 million to $119.8 million from $117.9
million. The lower gross profit margin for the second quarter of 1998 of 26.9
percent compared with 27.6 percent for 1997 was due principally to lower selling
prices in several businesses, partially offset by volume increases. During the
second quarter of 1998, efficiencies reflecting the integration of acquisitions
resulted in lower selling, general and administrative expenses as a percent of
sales compared with the same period of 1997. Meanwhile, research, development
and engineering was higher for 1998 when compared with the second quarter of
1997 due to increased manufacturing process development costs. Other expense,
net, was $2.2 million for the second quarter of 1998 compared with $3.6 million
for the same period of 1997. Income from operations for the second quarter of
1998 was $67.6 million, up 2.1 percent, compared with $66.2 million for the
second quarter of 1997.

The Company's net sales for the first six months of 1998 increased $27.6
million, or 3.4 percent, to $834.6 million compared with $807 million for the
same period of 1997. Gross profit decreased $3 million to $215.6 million from
$218.6 million.  The lower gross profit margin for the first half of 1998 of
25.8 percent compared with 27.1 percent for 1997 was due principally to lower
selling prices in several businesses, partially offset by volume increases.
Selling, general, administrative and research, development and engineering
expenses, combined, increased $4.5 million, or 4.7 percent, to $98.2 million.
These expenses were slightly higher as a percentage of sales, due in part to
acquisition-related costs and the impact of lower selling prices. Other expense,
net, was $3 million for the first six months of 1998 compared with $6.7 million
for the same period of 1997. Other income for 1998 included the proceeds from
the settlement of previously escrowed funds. Income from operations for the
first six months of 1998 was $114.3 million, down 3.2 percent, compared with
$118.2 million for the first six months of 1997.

Consistent with the Company's internal reporting, business segments discussed
below include allocated corporate expenses.

Insulation Segment

The Insulation segment's net sales decreased $4 million, or 2.3 percent, and
$13.8 million, or 3.9 percent, for the second quarter and first six months of
1998 compared with the same periods of 1997.  Income from operations decreased
$2.6 million, or 9.8 percent, and $7.8 million, or 15.2 percent, for the second
quarter and first six months of 1998 compared with the same periods of 1997.
Despite volume gains due to strong U.S. construction markets, the building
insulation business experienced continued pricing pressures during the first
quarter and the early part of the second quarter of 1998 compared with 1997.
These lower selling prices, which have recently 

                                      I-9

<PAGE>
 
improved, led to lower margins and an overall decrease in operating income
during the second quarter and first six months of 1998. During the second
quarter of 1998, competition from alternate materials resulted in lower sales of
automotive products, while other commercial/industrial businesses were
negatively impacted by downtime for equipment upgrades. For the first six months
of 1998, however, these declines were partially offset by higher selling prices
in mechanical insulations.

Roofing Systems Segment

Net sales for the Roofing Systems segment increased $10.8 million, or 7.9
percent, and $17.2 million, or 7.3 percent, for the second quarter and first six
months of 1998 compared with the same periods of 1997 due to incremental volume
increases from the recent thermoplastic membranes acquisitions. Excluding the
impacts of acquisitions, net sales moderately declined for the second quarter
and first six months of 1998 compared with 1997, reflecting decreased roofing
activity caused by adverse weather conditions in early 1998.  Income from
operations for the second quarter of 1998 increased slightly to $16.3 million
from $16 million for the second quarter of 1997 due to acquisitions and
favorable construction markets in the U.S. and Canada. However, operating income
decreased slightly for the first six months to $21.1 million from $21.8 million
as a result of acquisition costs and the impact of weather-related construction
delays.

Engineered Products Segment

The Engineered Products segment's net sales increased $9.1 million, or 7.5
percent, and $18.9 million, or 7.9 percent, for the second quarter and first six
months of 1998 compared with the same periods of 1997. Income from operations
increased $3.8 million, or 16.2 percent, and $4.7 million, or 10.3 percent, for
the same periods. These increases are primarily due to volume increases from the
Company's European operations which include the May 1997 acquisition of Mitex
and the May 1998 acquisition of Tasso AB, both manufacturers of fiber glass wall
covering fabrics. Volume increases in the U.S. mats and fibers business were
partially offset by weather-related declines in roofing mat shipments and lower
selling prices. Results in filtration decreased for the second quarter and first
six months of 1998 due to lower selling prices.

Interest Expense

The Company's interest expense decreased $3 million and $3.6 million for the
second quarter and the first six months of 1998 compared with the same periods
of 1997 primarily due to the purchase of substantially all of the Company's $400
million of 10 7/8% Senior Notes in May 1998 using revolving credit facilities
with significantly lower interest rates.

Debt

In May 1998, the Company consummated a cash tender offer for substantially all
of its $400 million of 10 7/8% Senior Notes due 2004 (the "Senior Notes").  This
transaction resulted in an extraordinary loss on the early extinguishment of
debt of $30.1 million, net of taxes of $19.8 million, in the second quarter of
1998.  In conjunction with the tender offer, the Company arranged unsecured
multicurrency revolving credit facilities (the "credit facilities") totaling
approximately $750 million at a floating interest rate of LIBOR plus an
additional margin, with an initial termination date of May 15, 2003.  The
Company used $450 million 

                                      I-10
<PAGE>
 
of the credit facilities to repurchase the Senior Notes. At June 30, 1998, $411
million of borrowings under the credit facilities were outstanding. The
remaining credit facilities are available for funding acquisitions and capital
expenditures, and other corporate purposes. The Company also canceled its $100
million receivables sale facility and its $75 million revolving line of credit
available to international subsidiaries.

Cumulative Effect of Accounting Change

Effective January 1, 1998, the Company changed its method of accounting for
glass furnace rebuild costs to the capitalization method from the allowance
method.  The cumulative effect of this change in accounting principle increases
1998 earnings by $27.4 million, net of taxes of $17.9 million.  This change
resulted in an increase in depreciation expense but eliminated the provision for
furnace rebuilds.  The pro forma effect of this change on net income was not
material.

Due to the factors discussed above, the Company's net income for the second
quarter of 1998 was $5.1 million compared with net income of $31 million for the
second quarter of 1997.  Year-to-date net income for 1998 was $53.1 million
compared with $54 million for the same period of 1997.

LIQUIDITY AND CAPITAL RESOURCES

The Company's agreements with its lenders contain financial and general
covenants. These include, among other things, limitations on borrowings,
investments and asset dispositions, and maintenance of various financial ratios.
Noncompliance with these or other covenants, or the occurrence of any other
event of default, could result in the termination of existing credit agreements
and the acceleration of debt owed by the Company and its subsidiaries.  At June
30, 1998, the Company was in compliance with these covenants.

At June 30, 1998, the Company had net working capital of $200.3 million,
including cash and marketable securities totaling $19.7 million.  Total cash and
marketable securities located outside the U.S. and Canada were approximately
$15.3 million.  At December 31, 1997, the Company's cash and marketable
securities totaled $122.4 million.  The Company had approximately $330 million
available for use at June 30, 1998 from its unsecured multicurrency revolving
credit facilities.  In addition, the Company's international subsidiaries had
borrowing and working capital facilities totaling approximately $10 million, of
which $7.3 million was available at June 30, 1998.

The Company's net operating activities provided $9.7 million of cash during the
first half of 1998.  Net operating activities for the same period of 1997
provided $20.1 million.  Operating activities for 1998 included the impact of
the premium on the prepayment of the Senior Notes.  The Company's cash flows
from operating activities are primarily influenced by sales volume and selling
prices.  As discussed in "Results of Operations," the effects of increased sales
volumes were partially offset by lower selling prices during 1998.  Operating
activities for 1998 also included cash usages to build net working capital for
the construction season, which typically peaks during the third quarter.  The
Company expects 1998 operating results to continue to benefit from the
integration of acquisitions.  A moderately higher level of U.S. housing 

                                     I-11
<PAGE>
 
starts during 1998 compared with 1997, in addition to recent price improvements,
should continue to benefit the building insulation business. Capacity-related
competitive pricing pressures are expected to stabilize for the building
insulation, mats and fibers and filtration businesses during the year.

The Company's investing activities for the six months ended June 30, 1998
included $55 million for acquisitions and capital expenditures of $52.4 million.
The Company estimates 1998 capital expenditures of approximately $128 million,
of which approximately $55 million relate to capacity expansion projects.  As of
June 30, 1998, outstanding purchase commitments for capital projects totaled $19
million.  Investing activities for the first half of 1997 included the combined
purchase prices for acquisitions of $93 million, net of cash acquired, and
capital expenditures of $47.1 million.

The Company's financing activities for the first half of 1998 consisted of
repayments of debt totaling $422.8 million and issuances of debt totaling $411.2
million, net, relating primarily to the May 1998 Senior Note purchase.  During
1997, the Company borrowed $55 million from international credit facilities to
partially finance 1997 acquisitions, of which $10 million was repaid by June 30,
1997.  The remainder was repaid by April 1998.  Also during 1997, the Company
repaid debt totaling $30 million assumed in connection with 1996 acquisitions.
This debt was refinanced with $30 million of notes payable to Johns Manville
Corporation at prevailing market terms, of which $2.5 million was repaid.

Contingent Product Liability

Between 1988 and 1992, the Company manufactured phenolic roofing insulation
which may, under certain circumstances, contribute to the corrosion of metal
decks on which it is installed.  Subsequently, the Company began a voluntary
program to inspect such metal decks and remediate where appropriate.  The
Company has accrued for costs relating to future inspections, remediation and
anticipated claims.  These accruals are based on the Company's historical
experience regarding the incidence of corrosion and the cost of remediation and
include a number of assumptions related to the types of roofs on which phenolic
insulation has been installed as well as the assumption that the Company's past
remediation experience will continue over the remaining lives of roofs insulated
with the Company's phenolic roofing insulation.

Pursuant to reimbursement agreements with the Company's liability carriers and
former owner of the phenolic roofing insulation business, the Company has been
reimbursed for a portion of historical costs incurred and is entitled to receive
reimbursement for a substantial portion of future costs to be incurred by the
Company for inspection and remediation.

In 1996, the Company and a third party were named as defendants in two class
action cases, now consolidated, filed in U.S. District Court in Boston,
Massachusetts.  The plaintiffs purport to represent all building owners in the
U.S. with phenolic insulation installed on their roof decks and seek damages and
injunctive relief, including an order requiring the removal and replacement of
the phenolic insulation and remediation of any deck corrosion.  The Company
intends to defend these allegations vigorously.

                                     I-12
<PAGE>
 
The Company has reviewed its historical inspection and remediation experience
and the terms and collectibility of amounts payable under the reimbursement
agreements in light of the contingencies described above.  Based on the
information available to date and subject to the assumptions described above, if
additional costs are incurred in excess of the accrued amounts, such costs are
not expected to have a material adverse effect on the Company's financial
condition, liquidity or results of operations.

Environmental Contingencies

At June 30, 1998, the Company had remediation activities in progress at nine
sites, out of a total of 19 such sites for which the Company has identified
environmental conditions requiring remediation.  In addition, the Company has
been identified as a potentially responsible party at 25 non-Company owned or
operated sites under the federal Comprehensive Environmental Response,
Compensation and Liability Act ("CERCLA") or similar state legislation.  Of
these 25 sites, the Company's potential liability for 19 sites will be
determined pursuant to the settlement agreement described in the following
paragraph.  The remaining six sites are not subject to the agreement and,
accordingly, the Company could be jointly and severally liable for costs of
remediating these sites.

In 1994, the U.S. government and the Company settled certain litigation
concerning the Company's disposal activities prior to consummation of its plan
of reorganization. The settlement agreement, which was made an order of the
court, limits the Company's future liability under both CERCLA and the Resource
Conservation and Recovery Act ("RCRA") to 55 percent of its share of site-wide
response costs and natural resources damages without regard to joint and several
liability for disposals made by the Company prior to consummation of the
Company's plan of reorganization.  The agreement resolved the Company's
liability at certain historical sites and also covers CERCLA and RCRA liability
for other disposal sites at which the Environmental Protection Agency ("EPA")
has incurred or may incur response costs and which were used by the Company
prior to the consummation of the plan of reorganization.  The agreement provides
that the amount the Company will be obligated to pay, in the aggregate, for such
sites shall never exceed $850,000 during any given year.  The EPA and others
from time to time commence cleanup activities at such sites, and in the future,
the EPA and others may assert claims against the Company with respect to such
sites.  The Company believes that all such activities and claims, if any, will
be subject to the agreement.

As a result of factors such as changes in federal and state regulations, the
application and effectiveness of remedial actions, the difficulty in assessing
the extent of environmental contamination, and the allocation of costs among
potentially responsible parties, actual costs to be incurred for environmental
cleanup may vary from previous estimates.  Subject to the uncertainties inherent
in evaluating environmental exposures, and based on information presently
available, including the Company's historical remediation experience, currently
enacted environmental laws and regulations, and existing remediation technology,
the Company believes that if additional costs are incurred in excess of the
accrued amounts, such costs are not expected to have a material adverse effect
on the Company's financial condition, liquidity or results of operations.

                                     I-13

Year 2000 Compliance

The Company is engaged in a comprehensive project, including the development of
appropriate contingency plans, to modify its computer software for year 2000
compliance. Based on current estimates, spending to upgrade or replace the
Company's embedded technology, software and systems related to year 2000
compliance is not expected to exceed $5 million through the completion of the
project in 1999. The majority of these costs relate to embedded technology. The
Company is currently working with third parties to address year 2000 readiness.
Although the impacts cannot currently be quantified, third party noncompliance
is not expected to have material adverse effects on the Company's financial
condition, liquidity or results of operations.

Pending Acquisitions

In May 1998, the Company announced an agreement in principle to acquire the
Spunbond/Monofilament operations of the Hoechst Group's polyester business
subject to regulatory approvals.  The acquisition, with 1997 sales totaling
approximately $250 million, will be part of the Engineered Products segment.
Also in May 1998, the Company announced it had signed a letter of intent to
acquire Manson Insulation, a Canadian producer of fiber glass pipe insulation,
duct insulation, OEM products and metal building insulation.


The Company believes that its current cash position, funds available under
credit facilities, and cash generated from operations will enable it to satisfy
its debt service requirements, its ongoing capital expansion program and its
other ongoing operating costs.  However, the Company may need to access capital
markets to pay the principal of its credit facilities, or in connection with
possible significant future acquisitions.

FORWARD-LOOKING STATEMENTS

This report contains "forward-looking statements" within the meaning of the
Private Securities Litigation Reform Act of 1995.  Statements of the Company
contained in this report concerning matters that are not historical facts,
including, without limitation, statements concerning the (i) expected benefits
from the continuing integration of acquisitions and capacity expansions, (ii)
effect on the building insulation business resulting from 1998 U.S. housing
starts, (iii) possible price stabilization in the current year in the building
insulation, mats and fibers and filtration businesses, (iv) Company's
expectations concerning levels of capital spending and funding of current
operations, debt service and future acquisitions, (v) Company's expectations as
to contingencies related to phenolic roofing insulation and environmental
liabilities, and (vi) Company's estimates concerning year 2000 compliance
issues, constitute such forward-looking statements.  See "Liquidity and Capital
Resources."

Forward-looking statements of the Company are subject to risks and uncertainties
that could cause actual results to differ materially from those expressed in
such statements.  Important factors relating to such risks and uncertainties are
set forth below.

                                     I-14
<PAGE>
 
Factors that could affect the forward-looking statements generally are related
to demand for the Company's products, overall capacity levels in the industry
and the overall competitive environment in which the Company operates. These
factors are discussed in detail in "Management's Discussion and Analysis of
Financial Condition and Results of Operations" incorporated in the Company's
Annual Report on Form 10-K for the year ended December 31, 1997.

Factors that could affect the Company's refinancing intentions and expected
levels of capital spending and funding of current operations and debt service,
include, without limitation, the general factors noted above, the level of cash
flow  generated by the Company and the ability of the Company to otherwise fund
such commitments, which in turn could be affected by general U.S. and
international economic conditions as well as financial market conditions.

The Company's ability to realize expected benefits from acquisitions depends on
a number of factors including, without limitation, successful integration of
newly acquired operations, technology, products, employees and the overall
economic factors referred to above.

For a discussion of factors concerning contingencies related to phenolic roofing
insulation, environmental matters and year 2000 compliance, see "Liquidity and
Capital Resources - Contingent Product Liability, Environmental Contingencies,
and Year 2000 Compliance."

          2.3  Procedure for Borrowing.  (a) Each Borrowing of Revolving Loans
               -----------------------                                        
shall be made upon the Borrowers' Designee's irrevocable written notice
delivered to the Agent in the form of a Notice of Borrowing (which notice must
be received by the Agent (i) prior to 9:00 a.m. (San Francisco time) four
Business Days prior to the requested Borrowing Date, in the case of Offshore
Currency Loans; (ii) prior to 9:00 a.m. (San Francisco time) three Business Days
prior to the requested Borrowing Date, in the case of Offshore Rate Loans
denominated in Dollars; and (iii) prior to 8:00 a.m. (San Francisco time) on the
requested Borrowing Date, in the case of Base Rate Loans, specifying:

           (A) the identity of the applicable Borrower;

           (B) the amount of the Borrowing, which shall be in a Minimum Amount;

           (C) the requested Borrowing Date, which shall be a Business Day;

           (D) the Type of Loans comprising the Borrowing;

                                      21
<PAGE>
 
            (E) in the case of a Borrowing comprised of Offshore Currency Loans,
          the Applicable Currency; and

            (F) if applicable, the duration of the Interest Period applicable to
          such Loans included in such notice, subject to the provisions of the
          definition of "Interest Period" herein.  If the Notice of Borrowing
          fails to specify the duration of the Interest Period for any Borrowing
          comprised of Offshore Rate Loans, such Interest Period shall be one
          month.

Upon receipt of any Notice of Borrowing of Revolving Loans, the Agent will
promptly notify each Bank thereof and of the amount of such Bank's Pro Rata
Share of the Borrowing (expressed in the Applicable Currency of the Borrowing).

          (b) Each Bank will make the amount of its Pro Rata Share of each
Borrowing of Revolving Loans available to the Agent for the account of the
Company (or other Borrower, as the case may be) at the Agent's Payment Office on
the Borrowing Date requested by the Borrowers' Designee in Same Day Funds and in
the requested currency (i) in the case of a Borrowing comprised of Loans in
Dollars, by 11:00 a.m. (San Francisco time), and (ii) in the case of a Borrowing
comprised of Offshore Currency Loans, by such time as the Agent may reasonably
specify.  The proceeds of all such Borrowings will then be made available to the
applicable Borrower by the Agent at such office by crediting the account of the
Company (or such other Borrower, as the case may be) on the books of BofA with
the aggregate of the amounts made available to the Agent by the Banks and in
like funds as received by the Agent, or if requested by Borrowers' Designee, by
wire transfer in accordance with written instructions provided to the Agent by
the Borrowers' Designee of such funds as received by the Agent, less customary
fees for such wire transfer, unless on the date of the Borrowing all or any
portion of the proceeds thereof shall then be required to be applied to the
repayment of any outstanding Loans or the reimbursement of any outstanding
drawings under Letters of Credit, in which case such proceeds or portion thereof
shall be applied to the payment of such Loans or the reimbursement of such
Letter of Credit drawings, as the case may be.

          (c) After giving effect to any Borrowing, unless the Agent shall
otherwise consent, there may not be more than 15 different Interest Periods in
effect with respect to any Revolving Loans.

          2.4  Conversion and Continuation Elections.  (a) The Borrowers'
               -------------------------------------

2.4(b):

            (i) elect, as of any Business Day, in the case of Base Rate Loans of
          a Borrower (other than Swingline Loans), or as of the last day of the
          applicable Interest Period, in the case of any Offshore Rate Loans of
          a Borrower denominated in Dollars, to convert any such Loans (or any
          part thereof in an amount not less than a Minimum Amount) into Loans
          in Dollars of any other Type; or

            (ii) elect, as of the last day of the applicable Interest Period, to
          continue any Offshore Rate Loans of a Borrower having Interest Periods
          expiring on such day (or any part thereof in an amount not less than a
          Minimum Amount) as Offshore Rate Loans of the same currency;

                                      22
<PAGE>
 
provided, that if at any time the aggregate amount of Offshore Rate Loans of a
Borrower denominated in Dollars in respect of any Borrowing is reduced, by
payment, prepayment, or conversion of part thereof to be less than $5,000,000,
such Offshore Rate Loans in Dollars shall automatically convert into Base Rate
Loans, and on and after such date the right of such Borrower to continue such
Loans as, and convert such Loans into, Offshore Rate Loans shall terminate.

          (b) Each such conversion and continuation of Revolving Loans shall be
made upon delivery by the Borrowers' Designee of a Notice of
Conversion/Continuation to the Agent.  Each such Notice of
Conversion/Continuation must be received by the Agent (i) not later than 8:00
a.m. (San Francisco time) three Business Days in advance of the
Conversion/Continuation Date, if any Offshore Rate Loans in Dollars are to be
converted into or continued as Offshore Rate Loans denominated in Dollars; (ii)
not later than 9:00 a.m. (San Francisco time) four Business Days in advance of
the Conversion/Continuation Date, if any Offshore Currency Loans are to be
continued as Offshore Currency Loans; and (iii) not later than 9:00 a.m. (San
Francisco time) on the Conversion/ Continuation Date, if the Loans are to be
converted into Base Rate Loans, specifying:

           (A) the identity of the applicable Borrower;

           (B) the proposed Conversion/Continuation Date;

           (C) the aggregate amount of Loans to be converted or continued;

           (D) the Type of Loans resulting from the proposed conversion or
          continuation; and

           (E) other than in the case of conversions into Base Rate Loans, the
          duration of the requested Interest Period.

          (c) If upon the expiration of any Interest Period applicable to
Offshore Rate Loans in Dollars, the Borrowers' Designee has failed to select
timely a new Interest Period to be applicable to such Offshore Rate Loans, or if
any Event of Default then exists, the Borrowers' Designee shall be deemed to
have elected to convert such Offshore Rate Loans into Base Rate Loans effective
as of the expiration date of such Interest Period.  If the Borrowers' Designee
has failed to select a new Interest Period to be applicable to any Offshore
Currency Loans prior to the fourth Business Day in advance of the expiration
date of the current Interest Period applicable thereto as provided in subsection
2.4(b), or if any Event of Default shall then exist, subject to the provisions
of subsection 2.5(d), the Borrowers' Designee shall be deemed to have elected to
continue such Offshore Currency Loans on the basis of a one month Interest
Period.

          (d) The Agent will promptly notify each Bank of its receipt of a
Notice of Conversion/Continuation of Revolving Loans, or, if no timely notice is
provided by the Borrowers' Designee, the Agent will promptly notify each Bank of

Revolving Loans shall be made ratably according to the respective outstanding
principal amounts of the Loans with respect to which the notice was given held

          (e) Unless the Majority Banks otherwise consent, during the existence
of an Event of Default, the Borrowers' Designee may not elect to have a Loan in
Dollars converted into or continued as an Offshore Rate Loan or to have any
Offshore Currency Loan continued on the basis of an Interest Period exceeding
one month.

          (f) After giving effect to any conversion or continuation of Loans,
unless the Agent shall otherwise consent, there may not be more than 15

          2.5  Utilization of Commitments in Offshore Currencies.  (a) The Agent
               -------------------------------------------------                
will determine the Dollar Equivalent Amount with respect to any (i) Borrowing
comprised of Offshore Currency Loans as of the requested Borrowing Date, (ii)
outstanding Offshore Currency Loans as of the last Business Day of each calendar
quarter, (iii) Letters of Credit to be Issued in an Offshore Currency as of the
requested date of Issuance, (iv) outstanding Letters of Credit denominated in an
Offshore Currency as of the last Business Day of each calendar quarter, and (v)
outstanding Offshore Currency Loans as of any redenomination date pursuant to
this Section 2.5, Section 3.3(c) or Section 4.2 (each such date under clauses
(i) through (v) a "Computation Date"); provided that the Majority Banks may in
                   ----------------    --------                               
writing instruct the Agent to determine such Dollar Equivalent Amount as of a
date in addition to the last Business Day of each calendar quarter, and the
Issuing Bank may in writing instruct the Agent to determine such Dollar
Equivalent Amount as of a conversion date (if not on the last Business Day of a
calendar quarter) in connection with a redenomination of any amounts payable in
an Offshore Currency pursuant to subsection 3.3(c), in which case such
alternative date or dates shall also be a Computation Date or Dates.

          (b) In the case of a proposed Borrowing of Revolving Loans comprised
of Offshore Currency Loans, the Banks shall be under no obligation to make such
Offshore Currency Loans in the requested Offshore Currency as part of such
Borrowing, if the Agent or the Banks shall determine that for any reason the
Banks cannot provide Loans in the requested Offshore Currency.  In such event
the Agent will promptly give notice to the Borrowers' Designee that the
Borrowing in the requested Offshore Currency is not then available, and notice
thereof also will be given promptly by the Agent to the Banks.  If the Agent
shall have so notified the Borrowers' Designee that any such Borrowing in a
requested Offshore Currency is not then available, the Borrowers' Designee may,
by notice to the Agent not later than 12:00 noon (San Francisco time) one
Business Day prior to the requested date of such Borrowing, withdraw the Notice
of Borrowing relating to such requested Borrowing.  If the Borrowers' Designee
does so withdraw such Notice of Borrowing, the Borrowing requested therein shall
not occur and the Agent will promptly so notify each Bank.  If the Borrowers'
Designee does not so withdraw such Notice of Borrowing, the Agent will promptly
so notify each Bank and such Notice of Borrowing shall be deemed to be a Notice
of Borrowing that requests a Borrowing comprised of Base Rate Loans in an
aggregate amount equal to the amount of the originally requested Borrowing as
expressed in Dollars in the Notice of Borrowing; and in such notice by the Agent
to each Bank the Agent will state such aggregate amount of such Borrowing in
Dollars and such Bank's Pro Rata Share thereof.

          (c) In the case of a proposed continuation of Revolving Loans
consisting of Offshore Currency Loans for an additional Interest Period pursuant
to Section 2.4, the Banks shall be under no obligation to continue such Offshore
Currency Loans if the Agent or the Banks 

                                      24
<PAGE>
 
shall determine that for any reason the Banks cannot continue to provide Loans
in the relevant Offshore Currency. In such event, the Agent will promptly give
notice to the Borrowers' Designee not later than 9:00 a.m. (San Francisco time)
on the Business Day following receipt of any such determination that the
continuation of such Offshore Currency Loans in the relevant Offshore Currency
is not then available, and notice thereof also will be given promptly by the
Agent to the Banks. If the Agent shall have so notified the Borrowers' Designee
that any such continuation of Offshore Currency Loans is not then available, any
Notice of Continuation/Conversion with respect thereto shall be deemed withdrawn
and such Offshore Currency Loans shall be redenominated into Base Rate Loans in
Dollars with effect from the last day of the Interest Period with respect to any
such Offshore Currency Loans. The Agent will promptly notify the Borrowers'
Designee and the Banks of any such redenomination and the redenomination date
and in such notice by the Agent to each Bank the Agent will state the aggregate
Dollar Equivalent Amount of the redenominated Offshore Currency Loans as of the
Computation Date with respect thereto and such Bank's Pro Rata Share thereof.

          (d) Notwithstanding anything herein to the contrary, during the
existence of an Event of Default, upon the request of the Majority Banks, all or
any part of any outstanding Offshore Currency Loans shall be redenominated and
converted into Base Rate Loans in Dollars with effect from the last day of the
Interest Period with respect to any such Offshore Currency Loans.  The Agent
will promptly notify the Borrowers' Designee of any such redenomination and
conversion request.

          (e) The Borrowers' Designee shall be entitled to request that
Revolving Loans hereunder also be permitted to be made, and Letters of Credit
hereunder also be permitted to be issued, in any other lawful currency
constituting a eurocurrency (other than Dollars), in addition to the
eurocurrencies specified in the definition of "Offshore Currency" herein, that
in the opinion of the Banks is at such time freely traded and freely available
in the offshore interbank foreign exchange markets and is freely transferable
and freely convertible into Dollars (an "Agreed Alternative Currency").  The
                                         ---------------------------        
Borrowers' Designee shall deliver to the Agent any request for designation of an
Agreed Alternate Currency in accordance with Section 11.2, to be received by the
Agent not later than 10:00 a.m. (San Francisco time) at least fifteen Business
Days in advance of the date of any Borrowing hereunder proposed to be made in
such Agreed Alternate Currency or any Letter of Credit proposed to be Issued
hereunder in such Agreed Alternate Currency.  Upon receipt of any such request
the Agent will promptly notify the Banks thereof, and each Bank will use its
best efforts to respond to such request within three Business Days of receipt
thereof.  Each Bank may grant or accept such request in its sole discretion.
The Agent will promptly notify the Borrowers' Designee of the acceptance or
rejection of any such request.  Acceptance of such request shall be subject to
unanimous Bank approval.

Amount of all Swingline Loans plus the Effective Amount of all Revolving Loans
plus the Effective Amount of all L/C Obligations exceed the Aggregate
Commitment, or (ii) the Effective Amount of all Swingline Loans exceed the
Swingline Commitment. Additionally, all Swingline Loans shall at all times be

Swingline Bank and the Borrowers' Designee. Within the foregoing limits, and
subject to the other terms and conditions hereof, each Borrower may borrow under

written notice (including notice via facsimile confirmed immediately by a
telephone call) in the form of a Notice of Borrowing of any Swingline Loan
requested hereunder (which notice must be received by the Agent prior to 11:00

amount to be borrowed, which shall be in a Minimum Amount (unless otherwise
agreed by the Swingline Bank), and (ii) the requested Borrowing Date, which

12:00 noon (San Francisco time) on such Borrowing Date from the Agent (including
at the request of any Bank) (A) directing the Swingline Bank not to make the
requested Swingline Loan as a result of the limitations set forth in the proviso
                                                                         -------

may be) on the books of BofA or if requested by the Borrowers' Designee, by wire
transfer in accordance with written instructions provided to the Agent by the
Borrowers' Designee, less customary fees for such wire transfer.  The Agent will

during such quarter.

          (c) Each Borrower shall repay to the Swingline Bank in full on the
Revolving Termination Date the aggregate principal amount of the Swingline Loans

Swingline Loans made to such Borrower in whole to the extent required so that a
Clean-Up Day may occur in each such ten Business Day period as provided in this
subsection 2.6(d) (which Swingline Loans may not be reborrowed until such Clean-
Up Day has ended).

          principal amount of such Swingline Loans; nor

                 (B) any other notice indicating the applicable Borrower's
          intent to repay such Swingline Loans with funds obtained from other
          sources; or

            (ii) any Swingline Loans shall remain outstanding during the
          existence of a Default or Event of Default and the Swingline Bank
          shall in its sole discretion notify the Agent that the Swingline Bank

Borrowers' Designee pursuant to Section 2.3 requesting that Base Rate Loans be
made pursuant to subsection 2.1(a) on such Clean-Up Day (in the case of the
circumstances described in clause (i) above) or on the first Business Day
subsequent to the date of such notice from the Swingline Bank (in the case of
the circumstances described in clause (ii) above) in an amount equal to the
aggregate amount of such Swingline Loans, and the procedures set forth in
subsections 2.3(b) and 2.3(c) shall be followed in making such Base Rate Loans;

of Revolving Loans becomes legally impracticable and if so required by the
Swingline Bank at the time such Revolving Loans are required to be made by the
Banks in accordance with this subsection 2.6(e), each Bank agrees that in lieu
of making Revolving Loans as described in this subsection 2.6(e), such Bank
shall purchase a participation from the Swingline Bank in the applicable
Swingline Loans in an amount equal to such Bank's Pro Rata Share of such
Swingline Loans, and the procedures set forth in subsections 2.3(b) and 2.3(c)
shall be followed in connection with the purchases of such participations.  Upon
such purchases of participations the prepayment requirements of subsection
2.6(d) shall be deemed waived with respect to such Swingline Loans.  The
proceeds of such Base Rate Loans shall be applied to repay such Swingline Loans.
If any Swingline Loan shall remain outstanding in lieu of a Borrowing of
Revolving Loans as provided above, interest on such Swingline Loan shall be due
and payable on demand.  A copy of each notice given by the Agent to the Banks
pursuant to this subsection 2.6(e) with respect to the making of Revolving
Loans, or the purchases of participations, shall be promptly delivered by the
Agent to the Borrowers' Designee.  Each Bank's obligation in accordance with
this Agreement to make the Revolving Loans, or purchase the participations, as
contemplated by this subsection 2.6(e), shall be absolute and unconditional and
shall not be affected by any circumstance, including (1) any set-off,
counterclaim, recoupment, defense or other right which such Bank may have
against the Swingline Bank, any Loan Party or any other Person for any reason
whatsoever; (2) the occurrence or continuance of a Default, an Event of Default
or a Material Adverse Effect; or (3) any other circumstance, happening or event
whatsoever, whether or not similar to any of the foregoing.

any Computation Date the Agent shall have determined that the Dollar Equivalent
Amount of the aggregate principal amount of all Revolving Loans, Swingline Loans
and L/C Obligations then outstanding exceeds the Aggregate Commitment by more
than $500,000, due to a change in applicable rates of exchange between Dollars
and Offshore Currencies, then the Agent shall give notice to the Borrowers'

such prepayment the aggregate Dollar Equivalent Amount of all Revolving Loans,
Swingline Loans and L/C Obligations does not exceed the Aggregate Commitment.

practice in the London interbank market or, as the case may be, the other
applicable Paris interbank market for the basis of accrual of interest or fees
in 

                                      29
<PAGE>
 
respect of the euro, such convention or practice shall replace such expressed
basis effective as of and from the date on which such state becomes a
participating member state; provided, that if any Offshore Currency Loan in the
                            --------                                           
currency of such state is outstanding immediately prior to such date, such
replacement shall take effect, with respect to such Loan, at the end of the then
current Interest Period.

          (j) Rounding and Other Consequential Changes.  Without prejudice and
              ----------------------------------------                        
in addition to any method of conversion or rounding prescribed by any EMU
legislation and without prejudice to the respective liabilities for Indebtedness
of the Borrowers to the Banks and the Banks to the Borrowers under or pursuant
to this Agreement:  (i) each reference in this Agreement to a minimum amount (or
an integral multiple thereof) in a national currency unit to be paid to or by
the Agent shall be replaced by a reference to such reasonably comparable and
convenient amount (or an integral multiple thereof) in the euro unit as the
Agent may from time to time specify; and (ii) except as expressly provided in
this Section 2.8, each provision of this Agreement shall be subject to such
reasonable changes of construction as the Agent may from time to time specify to
be necessary or appropriate to reflect the introduction of or changeover to the
euro in participating member states.

          (k) Increased Costs.  Each Borrower shall from time to time, at the
              ---------------                                                
request of the Agent, pay to the Agent for the account of each Bank the amount
of any cost or increased cost incurred by, or of any reduction in any amount
payable to or in the effective return on its capital to, or of interest or other
return foregone by, such Bank or any holding company of such Bank as a result of
the introduction of, changeover to or operation of the euro in any participating
member state, other than any such cost or reduction or amount foregone reflected
in any interest rate hereunder.

           2.9  Voluntary Termination or Reduction of Commitments.
                ------------------------------------------------- 

          (a) Each Borrower may, upon not less than three Business Days' prior
notice from the Borrowers' Designee to the Agent, terminate the Commitments, or
permanently reduce the Commitments by an aggregate minimum Dollar Equivalent
Amount of at least $5,000,000; unless, after giving effect thereto and to any
                               ------                                        
prepayments of any Loans made on the effective date thereof, (a) the Effective
Amount of all Revolving Loans, Swingline Loans and L/C Obligations together
would exceed the Aggregate Commitment then in effect, or (b) the Effective
Amount of all L/C Obligations then outstanding would exceed the L/C Commitment.
Once reduced in accordance with this Section 2.9, the Commitments may not be
increased.  Any reduction of the Commitments shall be applied to each Bank
according to its Pro Rata Share.  If and to the extent specified by the
Borrowers' Designee in the notice to the Agent, some or all of the reduction in
the Aggregate Commitment shall be applied to reduce the L/C Commitment and the
Swingline Commitment.  All accrued facility and letter of credit fees to, but
not including, the effective date of any termination of the Commitments shall be
paid on the effective date of such termination.  The Agent shall promptly
forward a copy of any such notice received under this subsection 2.9(a) to each
of the Banks.

          (b) At no time shall the Swingline Commitment exceed the Aggregate
Commitment, and any reduction of the Commitments (under this Section 2.9 or
under Section 2.12) which reduces the Aggregate Commitment below the then-
current amount of the Swingline Commitment shall result in an automatic
corresponding reduction of the Swingline Commitment to the amount of the
Aggregate Commitment, as so reduced, without any action on the part of the

                                      37
<PAGE>
 
Swingline Bank.  At no time shall the Swingline Commitment exceed the Commitment
of the Swingline Bank, and any reduction of the Commitments which reduces the
Commitment of the Swingline Bank below the then-current amount of the Swingline
Commitment shall result in an automatic corresponding reduction of the Swingline
Commitment to the amount of the Commitment of the Swingline Bank, as so reduced,
without any action on the part of the Swingline Bank.

          2.10  Optional Prepayments.  Subject to Section 4.4, each Borrower
                --------------------                                        
may, at any time or from time to time, upon notice from the Borrowers' Designee
to the Agent, (i) ratably prepay Revolving Loans in whole or in part, in minimum
Dollar Equivalent Amounts of at least $5,000,000 and (ii) ratably prepay
Swingline Loans in whole or in part, in minimum amounts of $500,000 or any
multiple of $100,000 in excess thereof, or in other amounts with the consent of
the Swingline Bank. The Borrowers' Designee shall deliver a notice of prepayment
in accordance with Section 11.2 to be received by the Agent (i) not later than
9:00 a.m. (San Francisco time) at least four Business Days in advance of the
prepayment date if the Loans to be prepaid are Offshore Currency Loans, (ii) not
later than 9:00 a.m. (San Francisco time) at least three Business Days in
advance of the prepayment date if the Loans to be prepaid are Offshore Rate
Loans in Dollars, and (iii) not later than 8:00 a.m. (San Francisco time) on the
prepayment date if the Loans to be prepaid are Base Rate Loans.  Such notice of
prepayment shall specify the date and amount of such prepayment and whether such
prepayment is of Base Rate Loans, Swingline Loans, Offshore Rate Loans, or any
combination thereof, and the Applicable Currency.  Such notice shall not
thereafter be revocable by the Borrowers' Designee.  The Agent will promptly
notify the Swingline Bank thereof (in the case of any prepayment of Swingline
Loans) and each Bank thereof and of such Bank's Pro Rata Share of such
prepayment (if any).  If such notice is given by the Borrowers' Designee, the
applicable Borrower shall make such prepayment and the payment amount specified
in such notice shall be due and payable on the date specified therein, together
with (other than in the case of Base Rate Loans) accrued interest to each such
date on the amount prepaid and any amounts required pursuant to Section 4.4.

          2.11  Mandatory Prepayments; Cash Collateralization.  If on any date
                ---------------------------------------------                 
the Effective Amount of L/C Obligations exceeds the L/C Commitment, the Company
shall Cash Collateralize on such date the outstanding Letters of Credit in an
amount equal to the excess of the maximum amount then available to be drawn
under the Letters of Credit over the L/C Commitment.  Subject to Section 4.4, if
on any date after giving effect to any Cash Collateralization made on such date
pursuant to the preceding sentence, the Effective Amount of all Revolving Loans
then outstanding plus the Effective Amount of all Swingline Loans then
                 ----                                                 
outstanding plus the Effective Amount of all L/C Obligations exceeds the
            ----                                                        
Aggregate Commitment, the Borrowers shall immediately, and without notice or
demand, prepay the outstanding principal amount of the Loans by an amount equal
to the applicable excess.

          2.12  Repayment of the Revolving Loans.  (a) Each Borrower shall repay
                --------------------------------                                
to the Agent for the account of the Banks on the Revolving Termination Date the
aggregate principal amount of Revolving Loans made to such Borrower and
outstanding on such date.

          (b) At the option of the Borrowers, upon written notice by the
Borrowers' Designee to the Agent to be given not more than 120 days but not
later than 30 days prior to the then applicable Revolving Termination Date, the
Borrowers' Designee may request that the Revolving Termination Date be extended
by successive one-year periods; provided, however, that each such one-year
                                --------  -------                         
extension shall require the unanimous approval of all of the Banks (such

                                      38
<PAGE>
 
approval to be within the sole discretion of each Bank) and the written consent
of each Loan Party; and provided further that if any Bank shall decline to
                        -------- -------                                  
approve of any such extension, the Borrowers' Designee may (i) on or prior to
the then applicable Revolving Termination Date, obtain a Replacement Bank to
acquire and assume all or part of the Loans and Commitment of such non-
consenting Bank in accordance with Section 4.8, or (ii) subject to repayment in
full on or prior to the then applicable Revolving Termination Date of all
Obligations then owing to each such non-consenting Bank, request that the
Revolving Termination Date be extended only with respect to such Banks as have
consented to such extension.  The Borrowers each acknowledge and agree that (A)
no Bank shall have any obligation to increase its Commitment hereunder or
otherwise acquire or assume all or any part of any other Bank's Loans or
Commitment, whether in connection with an extension of the Revolving Termination
Date pursuant to this subsection (b) or otherwise, and (B) in the event that
some but not all of the Banks consent to an extension of the Revolving
Termination Date pursuant this subsection (b) and the Borrowers' Designee
requests that the Revolving Termination Date be extended with respect to such
consenting Banks only, the Aggregate Commitment shall be automatically reduced
to an amount equal to the combined Commitments of the remaining Banks, subject
to Section 2.11.

          2.13  Interest.  (a) (i) Each Revolving Loan shall bear interest on
                --------                                                     
the outstanding principal amount thereof from the applicable Borrowing Date at a
rate per annum equal to the Offshore Rate or the Base Rate, as the case may be
(and subject to the Company's right to convert to another Type of Loans under
Section 2.4), plus the Applicable Margin (in the case of Offshore Rate Loans).
              ----                                                             
(ii) Each Swingline Loan shall bear interest on the outstanding principal amount
thereof from the applicable Borrowing Date at a rate per annum equal to the Base
Rate, or at such other rate as may be agreed to by the Swingline Bank.

          (b) Interest on each Revolving Loan and Swingline Loan shall be paid
in arrears on each Interest Payment Date.  Interest shall also be paid on the
date of any prepayment of Loans (other than Base Rate Loans) under Section 2.10
or 2.11 for the portion of the Loans so prepaid and upon payment (including
prepayment) of Loans (other than Base Rate Loans) in full thereof and, during
the existence of any Event of Default, interest shall be paid on demand of the
Agent at the request or with the consent of the Majority Banks.

          (c) Notwithstanding subsection (a) of this Section, if any amount of
principal of or interest on any Loan payable by any Borrower, or any other
amount payable by such Borrower hereunder or under any other Loan Document is
not paid in full when due (whether at stated maturity, by acceleration, demand
or otherwise), such Borrower agrees to pay interest on such unpaid principal or
other amount, from the date such amount becomes due until the date such amount
is paid in full, and after as well as before any entry of judgment thereon to
the extent permitted by law, payable on demand, (i) in the case of any overdue
amounts denominated in Dollars, at a rate per annum equal to the Base Rate plus
                                                                           ----
2% per annum, and (ii) during such periods as any such overdue amount is
denominated in an Offshore Currency, at a rate per annum equal during each
Default Interest Period for such overdue amount to the Offshore Rate for such
Default Interest Period plus the Applicable Margin plus 2%.  With respect to any
                        ----                       ----                         
overdue amount payable in an Offshore Currency, the Majority Banks in their sole
discretion may from time to time select interest periods of time of not more
than three months, as they shall deem appropriate (each such period a "Default
                                                                       -------
Interest Period").  The initial Default Interest Period shall begin on the date
- ---------------                                                                
on which the amount in default becomes due, and each succeeding Default Interest
Period shall begin on the day on which the next preceding Default Interest
Period expires.

                                      32
<PAGE>
 
          (d) Anything herein to the contrary notwithstanding, the obligations
of each Borrower to any Bank hereunder shall be subject to the limitation that
payments of interest shall not be required for any period for which interest is
computed hereunder, to the extent (but only to the extent) that contracting for
or receiving such payment by such Bank would be contrary to the provisions of
any law applicable to such Bank limiting the highest rate of interest that may
be lawfully contracted for, charged or received by such Bank, and in such event
such Borrower shall pay such Bank interest at the highest rate permitted by
applicable law.

           2.14  Fees.  In addition to certain fees described in Section 3.8:
                 ----                                                        

          (a) Arrangement and Agency Fees.  The Company shall pay an arrangement
              ---------------------------                                       
fee to the Arranger for the Arranger's own account, and shall pay an agency fee
to the Agent for the Agent's own account, as required by the letter agreement
between the Company and the Arranger and Agent dated March 31, 1998.

          (b) Facility Fees.  The Company shall pay to the Agent for the account
              -------------                                                     
of each Bank, a facility fee on the Aggregate Commitment, computed on a
quarterly basis in arrears on the last Business Day of each calendar quarter, as
calculated by the Agent, at a rate per annum equal to the Applicable Fee Amount.
Such facility fee shall be payable regardless of utilization of the Commitments
and shall accrue from the Closing Date to the Revolving Termination Date and
shall be due and payable quarterly in arrears on the last Business Day of each
calendar quarter commencing on June 30, 1998, through the Revolving Termination
Date, with the final payment to be made on the Revolving Termination Date;
                                                                          
provided that, in connection with any termination of Commitments under Section
- --------                                                                      
2.9, the accrued facility fee calculated for the period ending on such date
shall also be paid on the date of termination.  The facility fees provided in
this subsection shall accrue at all times after the above-mentioned commencement
date, including at any time during which one or more conditions in Article V are
not met.

          (c) Participation Fees.  The Company shall pay to the Agent for the
              ------------------                                             
benefit of the Banks, the participation fees set forth in the Fee Letter.  Such
participation fees shall be due and payable on the Closing Date and allocated
among the Banks in accordance with the Fee Letter.

          2.15  Computation of Fees and Interest.  (a) All computations of
                --------------------------------                          
interest for Base Rate Loans when the Base Rate is determined by BofA's
"reference rate" shall be made on the basis of a year of 365 or 366 days, as the
case may be, and actual days elapsed.  All other computations of fees and
interest shall be made on the basis of a 360-day year and actual days elapsed
(which results in more interest being paid than if computed on the basis of a
365-day year), except that interest shall accrue on the basis of the actual
number of days elapsed and a year of 365 days or 366 days, as the case may be,
in the case of Offshore Currency Loans denominated in any Offshore Currency in
respect of which interest is calculated on a 365/366-day in accordance with
customary practice in the applicable interbank market.  Interest and fees shall
accrue during each period during which interest or such fees are computed from
the first day thereof to the last day thereof.

          (b) Each determination of an interest rate or a Dollar Equivalent
Amount by the Agent or the Issuing Bank shall be conclusive and binding on the
Borrowers and the Banks in the absence of manifest error.

                                      33
<PAGE>
 
          2.16  Payments by the Company.  (a) All payments to be made by the
                -----------------------                                     
Borrowers shall be made without set-off, recoupment or counterclaim.  Except as
otherwise expressly provided herein, all payments by any Loan Party shall be
made to the Agent for the account of the Banks at the Agent's Payment Office,
and, with respect to principal of, interest on, and any other amounts relating
to, any Offshore Currency Loan, shall be made in the Offshore Currency in which
such Loan is denominated or payable, and, with respect to all other amounts
payable hereunder, shall be made in Dollars.  Such payments shall be made in
Same Day Funds, and (i) in the case of any Offshore Currency payments, no later
than such time on the dates specified herein as may be determined by the Agent
to be necessary for such payment to be credited on such date in accordance with
normal banking procedures in the place of payment, and (ii) in the case of any
Dollar payments, no later than 11:00 a.m. (San Francisco time) on the date
specified herein. Any payment which is received by the Agent later than 11:00
a.m. (San Francisco time) (in the case of any Dollar payments), or later than
the time specified by the Agent as provided in clause (i) above (in the case of
Offshore Currency payments), shall be deemed to have been received on the
following Business Day and any applicable interest or fee shall continue to
accrue.  The Agent will promptly distribute to each Bank its Pro Rata Share (or
other applicable share as expressly provided herein) of such payment in like
funds as received.

          (b) Subject to the provisions set forth in the definition of "Interest
Period" herein, whenever any payment is due on a day other than a Business Day,
such payment shall be made on the following Business Day, and such extension of
time shall in such case be included in the computation of interest or fees, as
the case may be.

          (c) Unless the Agent receives notice from a Borrower or the Borrowers'
Designee prior to the date on which any payment in Dollars or any Applicable
Currency is due to the Banks that such Borrower will not make such payment in
full as and when required, the Agent may assume that such Borrower has made such
payment in full to the Agent on such date in Same Day Funds and the Agent may
(but shall not be so required), in reliance upon such assumption, distribute to
each Bank on such due date an amount equal to the amount then due such Bank.  If
and to the extent such Borrower has not made such payment in full to the Agent,
each Bank shall repay to the Agent on demand such amount distributed to such
Bank, together with interest thereon at the Federal Funds Rate or, in the case
of a payment in an Offshore Currency, the Overnight Rate, for each day from the
date such amount is distributed to such Bank until the date repaid.

          2.17  Payments by the Banks to the Agent.  (a) Unless the Agent
                ----------------------------------                       
receives notice from a Bank on or prior to the Loan Availability Date or, with
respect to any Borrowing after the Loan Availability Date, at least one Business
Day prior to the date of such Borrowing, or, in the case of Base Rate Loans
only, not later than 10:00 a.m. (San Francisco time) on the date of such
Borrowing, that such Bank will not make available as and when required hereunder
to the Agent for the account of the applicable Borrower the amount of that
Bank's Pro Rata Share of the Borrowing, the Agent may assume that each Bank has
made such amount available to the Agent in Same Day Funds on the Borrowing Date
and the Agent may (but shall not be so required), in reliance upon such
assumption, make available to such Borrower on such date a corresponding amount.
If and to the extent any Bank shall not have made its full amount available to
the Agent in Same Day Funds and the Agent in such circumstances has made
available to such Borrower such amount, that Bank shall on the Business Day
following such Borrowing Date make such amount available to the Agent, together
with interest at the Federal Funds Rate or, in the case of 

                                      34
<PAGE>
 
any Borrowing consisting of Offshore Currency Loans, the Overnight Rate, for
each day during such period. A notice of the Agent submitted to any Bank with
respect to amounts owing under this subsection 2.17(a) shall be conclusive,
absent manifest error. If such amount is so made available, such payment to the
Agent shall constitute such Bank's Loan on the date of Borrowing for all
purposes of this Agreement. If such amount is not made available to the Agent on
the Business Day following the Borrowing Date, the Agent will notify the
Borrowers' Designee of such failure to fund and, upon demand by the Agent, such
Borrower shall pay such amount to the Agent for the Agent's account, together
with interest thereon for each day elapsed since the date of such Borrowing, at
a rate per annum equal to the interest rate applicable at the time to the Loans
comprising such Borrowing.

          (b) The failure of any Bank to make any Loan on any Borrowing Date
shall not relieve any other Bank of any obligation hereunder to make a Loan on
such Borrowing Date, but no Bank shall be responsible for the failure of any
other Bank to make the Loan to be made by such other Bank on any Borrowing Date.

          2.18  Sharing of Payments, Etc.  If, other than as expressly provided
                ------------------------                                       
elsewhere herein, any Bank shall obtain on account of the Loans made by it any
payment (whether voluntary, involuntary, through the exercise of any right of
set-off, or otherwise) in excess of its ratable share (or other share
contemplated hereunder), such Bank shall immediately (a) notify the Agent of
such fact, and (b) purchase from the other Banks such participations in the
Loans made by them as shall be necessary to cause such purchasing Bank to share
the excess payment pro rata with each of them; provided, however, that if all or
                                               --------  -------                
any portion of such excess payment is thereafter recovered from the purchasing
Bank, such purchase shall to that extent be rescinded and each other Bank shall
repay to the purchasing Bank the purchase price paid therefor, together with an
amount equal to such paying Bank's ratable share (according to the proportion of
(i) the amount of such paying Bank's required repayment to (ii) the total amount
so recovered from the purchasing Bank) of any interest or other amount paid or
payable by the purchasing Bank in respect of the total amount so recovered.
Each Loan Party agrees that any Bank so purchasing a participation from another
Bank may, to the fullest extent permitted by law, exercise all its rights of
payment (including the right of set-off, but subject to Section 11.10) with
respect to such participation as fully as if such Bank were the direct creditor
of such Loan Party in the amount of such participation.  The Agent will keep
records (which shall be conclusive and binding in the absence of manifest error)
of participations purchased under this Section and will in each case notify the
Banks following any such purchases or repayments.

           2.19  The Borrowers' Designee.
                 ----------------------- 

          (a) Each of the Borrowers hereby irrevocably appoints, designates and
authorizes the Borrowers' Designee to take such action on its behalf under the
provisions of this Agreement and each other Loan Document and to exercise such
powers and perform such duties as are expressly delegated to it by the terms of
this Agreement or any other Loan Document, together with such powers as are
reasonably incidental thereto. The Borrowers' Designee may execute any of its
duties under this Agreement or any other Loan Document by or through agents,
employees or attorneys-in-fact.

          (b) The Borrowers' Designee shall promptly forward to the Agent or the
Borrowers, as appropriate, all notices, certificates, financial statements and
reports received by it in the performance of its duties hereunder.

                                      35
<PAGE>
 
          (c) The Borrowers may, upon 30 days' notice to and with the consent of
the Agent (which consent shall not be unreasonably withheld), appoint another
Borrower to act as Borrowers' Designee and upon such appointment such successor
Borrowers' Designee shall succeed to all the appointment, powers and duties of
the retiring Borrowers' Designee and the term "Borrowers' Designee" shall mean
such successor designee and the retiring Borrowers' Designee's rights, powers
and duties as Borrowers' Designee shall be terminated.

          (d) The Borrowers' Designee shall perform its duties hereunder and
under the other Loan Documents on behalf of the Borrowers.  The action of the
Borrowers' Designee shall in each case bind all the Borrowers, and any action
taken by the Borrowers' Designee in the name of the Borrowers or any of them
pursuant to this Agreement or any other Loan Document shall bind the Borrowers,
whether or not such action has been duly authorized by such Borrowers.

          (e) Any agreement of the Agent and the Banks herein with respect to
the Borrowers' Designee is solely for the convenience and at the request of the
Borrowers.  The Agent and the Banks shall be entitled to rely on the authority
of any Person purporting to be a Person authorized by the Borrowers to act on
behalf of the Borrowers' Designee and the Agent and the Banks shall not have any
liability to the Borrowers or other Person on account of any action taken or not
taken by the Agent or the Banks in reliance thereon.

                             THE LETTERS OF CREDIT
                             ---------------------
                                        
          3.1  The Letter of Credit Subfacility.  (a) On the terms and
               --------------------------------                       
conditions set forth herein (i) the Issuing Bank agrees, (A) from time to time
on any Business Day during the period from the Loan Availability Date to the
Revolving Termination Date to issue Letters of Credit for the account of each
Borrower, and to amend or renew Letters of Credit previously issued by it, in
accordance with subsections 3.2(c) and 3.2(d), in an aggregate Dollar Equivalent
Amount not to exceed at any time the L/C Commitment, and (B) to honor drafts
under the Letters of Credit; and (ii) the Banks severally agree to participate
in Letters of Credit Issued for the account of each Borrower; provided, that the
                                                              --------          
Issuing Bank shall not be obligated to Issue, and no Bank shall be obligated to
participate in, any Letter of Credit if as of the date of Issuance of such
Letter of Credit and after giving affect thereto (the "Issuance Date") (1) the
                                                       -------------          
Effective Amount of all outstanding Revolving Loans plus the Effective Amount of
                                                    ----                        
all Swingline Loans plus the Effective Amount of all L/C Obligations, shall
                    ----                                                   
exceed the Aggregate Commitment; (2) the Effective Amount of the Revolving Loans
of any Bank plus the participation of such Bank in the Effective Amount of all
            ----                                                              
Swingline Loans plus the participation of such Bank in the Effective Amount of
                ----                                                          
all L/C Obligations, shall exceed such Bank's Commitment; or (3) the Effective
Amount of all L/C Obligations shall exceed the L/C Commitment.  Within the
foregoing limits, and subject to the other terms and conditions hereof, each
Borrower's ability to obtain Letters of Credit shall be fully revolving, and,
accordingly, any Borrower may, during the foregoing period, obtain Letters of
Credit to replace Letters of Credit which have expired or which have been drawn
upon and reimbursed.

           (b) The Issuing Bank is under no obligation to Issue any Letter of
Credit if:

                                      36
<PAGE>
 
           (i) any order, judgment or decree of any Governmental Authority or
     arbitrator shall by its terms purport to enjoin or restrain the Issuing
     Bank from Issuing such Letter of Credit, or any Requirement of Law
     applicable to the Issuing Bank or any request or directive (whether or not
     having the force of law) from any Governmental Authority with jurisdiction
     over the Issuing Bank shall prohibit, or request that the Issuing Bank
     refrain from, the Issuance of letters of credit generally or such Letter of
     Credit in particular;

           (ii) the Issuing Bank has received written notice from any Bank, the
     Agent or any Loan Party, on or prior to the Business Day prior to the
     requested date of Issuance of such Letter of Credit, that one or more of
     the applicable conditions contained in Article V is not then satisfied;

           (iii)  the expiry date of any requested Letter of Credit is (A) more
     than one year after the date of Issuance, unless the Majority Banks have
     approved such expiry date in writing, or (B) after the date five Business
     Days prior to the Revolving Termination Date;

           (iv) any requested Letter of Credit does not provide for drafts, or
     is not otherwise in form and substance acceptable to the Issuing Bank, or
     the Issuance of a Letter of Credit shall violate any applicable policies of
     the Issuing Bank;

           (v) any standby Letter of Credit is for the purpose of supporting the
     issuance of any letter of credit by any other Person; or

           (vi) such Letter of Credit is in a face amount less than $1,000,000
     (or the Dollar Equivalent Amount thereof in an Offshore Currency, as
     determined as of the Computation Date for an Offshore Currency Letter of
     Credit) or to be denominated in a currency other than Dollars or an
     Offshore Currency.

          3.2  Issuance, Amendment and Renewal of Letters of Credit.  (a) Each
               ----------------------------------------------------           
Letter of Credit shall be issued upon the irrevocable written request of the
Borrowers' Designee received by the Issuing Bank (with a copy sent by the
Borrowers' Designee to the Agent) at least four Business Days in the case of
Letters of Credit to be denominated in Dollars, and six Business Days in the
case of any Offshore Currency Letters of Credit (or such shorter time as the
Issuing Bank may agree in a particular instance in its sole discretion) prior to
the proposed date of issuance.  Each such request for issuance of a Letter of
Credit shall be by facsimile, confirmed immediately in an original writing, in
the form of an L/C Application, and shall specify in form and detail
satisfactory to the Issuing Bank: (i) the proposed date of issuance of the
Letter of Credit (which shall be a Business Day); (ii) the face amount of the
Letter of Credit (and applicable Offshore Currency in the case of a proposed
Offshore Currency Letter of Credit); (iii) the expiry date of the Letter of
Credit; (iv) the name and address of the beneficiary thereof; (v) the documents
to be presented by the beneficiary of the Letter of Credit in case of any
drawing thereunder; (vi) the full text of any certificate to be presented by the
beneficiary in case of any drawing thereunder; and (vii) such other matters as
the Issuing Bank may require. The Dollar Equivalent Amount of any Offshore
Currency Letter of Credit will be determined by the Agent for such Letter of
Credit on the Computation Date therefor in accordance with subsection 2.5(a).

                                      37
<PAGE>
 
          (b) At least two Business Days prior to the Issuance of any Letter of
Credit, the Issuing Bank will confirm with the Agent (by telephone or in
writing) that the Agent has received a copy of the L/C Application or L/C
Amendment Application from the Borrowers' Designee and, if not, the Issuing Bank
will provide the Agent with a copy thereof.  Unless the Issuing Bank has
received notice on or before the Business Day immediately preceding the date the
Issuing Bank is to issue a requested Letter of Credit from the Agent (A)
directing the Issuing Bank not to issue such Letter of Credit because such
issuance is not then permitted under subsection 3.1(a) as a result of the
limitations set forth in clauses (1) through (3) thereof or subsection
3.1(b)(ii); or (B) that one or more conditions specified in Article V are not
then satisfied; then, subject to the terms and conditions hereof, the Issuing
Bank shall, on the requested date, issue a Letter of Credit for the account of
the applicable Borrower in accordance with the Issuing Bank's usual and
customary business practices.

          (c) From time to time while a Letter of Credit is outstanding and
prior to the Revolving Termination Date, the Issuing Bank will, upon the written
request of the Borrowers' Designee received by the Issuing Bank (with a copy
sent by the Borrowers' Designee to the Agent) at least four Business Days in the
case of Letters of Credit denominated in Dollars, and six Business Days in the
case of Offshore Currency Letters of Credit (or such shorter time as the Issuing
Bank may agree in a particular instance in its sole discretion) prior to the
proposed date of amendment (including a renewal or extension thereof), amend any
Letter of Credit issued by it.  Each such request for amendment of a Letter of
Credit shall be made by facsimile, confirmed immediately in an original writing,
made in the form of an L/C Amendment Application and shall specify in form and
detail satisfactory to the Issuing Bank:  (i) the Letter of Credit to be
amended; (ii) the proposed date of amendment of the Letter of Credit (which
shall be a Business Day); (iii) the nature of the proposed amendment; and (iv)
such other matters as the Issuing Bank may require.  The Issuing Bank shall be
under no obligation to amend any Letter of Credit if:  (A) the Issuing Bank
would have no obligation at such time to issue such Letter of Credit in its
amended form under the terms of this Agreement; or (B) the beneficiary of any
such Letter of Credit does not accept the proposed amendment to the Letter of
Credit.  The Agent will promptly notify the Banks of the receipt by it of any
L/C Application or L/C Amendment Application and of the Issuance of any Letter
of Credit notified to it by the Issuing Bank.

          (d) The Issuing Bank and the Banks agree that, while a Letter of
Credit is outstanding and prior to the Revolving Termination Date, the Issuing
Bank shall be entitled to authorize the renewal of any Letter of Credit issued
by it which provides for such renewal.  The Issuing Bank shall be under no
obligation so to renew any Letter of Credit if: (A) the Issuing Bank would have
no obligation at such time to issue or amend such Letter of Credit in its
renewed form under the terms of this Agreement; or (B) the beneficiary of any
such Letter of Credit does not accept the proposed renewal of the Letter of
Credit.  If any outstanding Letter of Credit shall provide that it shall be
automatically renewed unless the beneficiary thereof receives notice from the
Issuing Bank that such Letter of Credit shall not be renewed, and if at the time
of renewal the Issuing Bank would be entitled to authorize the automatic renewal
of such Letter of Credit in accordance with this subsection 3.2(d) upon the
request of the Borrowers' Designee but the Issuing Bank shall not have received
any written direction by the Borrowers' Designee with respect thereto, the
Issuing Bank shall nonetheless be permitted to allow such Letter of Credit to
renew, and the applicable Borrower (as account party) and the Banks hereby
authorize such renewal, and, accordingly, the Issuing Bank shall be deemed to
have received an L/C Amendment Application from the Borrowers' Designee
requesting such renewal.

                                      38

          (e) The Issuing Bank may, at its election (or as required by the Agent
at the direction of the Majority Banks), deliver any notices of termination or
other communications to any Letter of Credit beneficiary or transferee, and take
any other action as necessary or appropriate, at any time and from time to time,
in order to cause the expiry date of such Letter of Credit to be a date not
later than the Revolving Termination Date.

          (f) This Agreement shall control in the event of any conflict with any
L/C-Related Document (other than any Letter of Credit).

          (g) The Issuing Bank will also deliver to the Agent, concurrently or
promptly following its delivery of a Letter of Credit, or amendment to or
renewal of a Letter of Credit, to an advising bank or a beneficiary, a true and
complete copy of each such Letter of Credit or amendment to or renewal of a
Letter of Credit.

          3.3  Existing BofA Letters of Credit; Risk Participations, Drawings
               --------------------------------------------------------------
and Reimbursements.  (a) On and after the Loan Availability Date, the Existing
- ------------------                                                            
BofA Letters of Credit shall be deemed for all purposes, including for purposes
of the fees to be collected pursuant to subsections 3.8(a) and 3.8(c), and
reimbursement of costs and expenses to the extent provided herein, Letters of
Credit outstanding under this Agreement and entitled to the benefits of this
Agreement and the other Loan Documents, and shall be governed by the
applications and agreements pertaining thereto and by this Agreement.  Each Bank
shall be deemed to, and hereby irrevocably and unconditionally agrees to,
purchase from the Issuing Bank on the Loan Availability Date a participation in
each such Letter of Credit and each drawing thereunder in an amount equal to the
product of (i) such Bank's Pro Rata Share times (ii) the maximum amount
available to be drawn under such Letter of Credit and the amount of such
drawing, respectively.  The Existing BofA Letters of Credit shall be deemed to
utilize the L/C Commitment and to utilize pro rata the Commitment of each Bank.

          (b) Immediately upon the Issuance of each Letter of Credit in addition
to those described in subsection 3.3(a), each Bank shall be deemed to, and
hereby irrevocably and unconditionally agrees to, purchase from the Issuing Bank
a participation in such Letter of Credit and each drawing thereunder in an
amount equal to the product of (i) the Pro Rata Share of such Bank, times (ii)
the maximum amount available to be drawn under such Letter of Credit and the
amount of such drawing, respectively.  Each Issuance of a Letter of Credit shall
be deemed to utilize the Commitment of each Bank by an amount equal to the
amount of such participation.

          (c) In the event of any request for a drawing under a Letter of Credit
by the beneficiary or transferee thereof, the Issuing Bank will promptly notify
the Borrowers' Designee and specify in such notice the date such drawing will be
honored by the Issuing Bank (the "Honor Date").  If the Issuing Bank so notifies
                                  ----------                                    
the Borrowers' Designee prior to 10:00 a.m. (San Francisco time) on the Honor
Date, the applicable Borrower, as account party under such Letter of Credit,
shall reimburse the Issuing Bank on the Honor Date for the amount paid by the
Issuing Bank under such Letter of Credit or, if the Issuing Bank shall so notify
the Borrowers' Designee after 10:00 a.m. (San Francisco time) on the Honor Date,
the applicable Borrower, as account party under such Letter of Credit, shall
reimburse the Issuing Bank by no later than 11:00 a.m. (San Francisco time) on
the next succeeding Business Day for the amount paid by the Issuing Bank under
such Letter of Credit on the Honor Date (each such date, a "Reimbursement
                                                            -------------
Date"), in each case, in an amount equal to the amount so paid by the Issuing
Bank and in the currency in which such Letter of Credit is payable.  Such
reimbursement shall be made by such Borrower no 

                                      39
<PAGE>
 
later than 2:00 p.m. (San Francisco time) in the case of reimbursement to be
made on the Honor Date, or 11:00 a.m. (San Francisco time) in the case of
reimbursement to be made on the next Business Day following the Honor Date. In
the event such Borrower fails to reimburse the Issuing Bank for the full amount
of any drawing under any Letter of Credit by the required time as provided above
on the Reimbursement Date, the Issuing Bank will promptly notify the Agent, and
the Agent will promptly notify each Bank thereof (including the amount thereof,
expressed in Dollars as specified below, and such Bank's Pro Rata Share
thereof), and the Borrowers' Designee shall be deemed to have requested that
Base Rate Loans be made by the Banks to such Borrower to be disbursed on the
Reimbursement Date for such Letter of Credit, subject to the amount of the
unutilized portion of the Aggregate Commitment and subject to the conditions set
forth in Section 5.3. In the case of any drawing under an Offshore Currency
Letter of Credit, the Issuing Bank shall redenominate the unreimbursed drawing
into Dollars as of the Honor Date, and shall notify the Agent of the Dollar
Equivalent Amount thereof, and upon notice by the Agent to the Banks, such Loans
shall be funded by each Bank in Dollars, in an amount equal to such Bank's Pro
Rata Share of the Dollar Equivalent Amount of the unreimbursed drawing as of the
Honor Date. Each Borrower hereby directs that the proceeds of any such Loans
deemed to be made by it shall be used to pay its reimbursement obligations in
respect of any such drawing. Solely for the purposes of making such Loans, the
Minimum Amount limitations set forth in Section 2.3 shall not be applicable. Any
notice given by the Issuing Bank or the Agent pursuant to this subsection 3.3(c)
may be oral if immediately confirmed in writing (including by facsimile);
provided that the lack of such an immediate confirmation shall not affect the
conclusiveness or binding effect of such notice. In the event that any amount of
any drawing under any Letter of Credit is not reimbursed by the applicable
Borrower on the Honor Date, the Dollar Equivalent Amount (as of the Honor Date)
of such unreimbursed amount shall bear interest until it is either deemed to be
an L/C Borrowing as provided in subsection (e) or deemed to be converted to a
Base Rate Loan as provided in this subsection (c) at a rate per annum equal to
the Base Rate.

          (d) Each Bank shall upon receipt of any notice pursuant to subsection
3.3(c) make available to the Agent for the account of the Issuing Bank an amount
in Dollars and in Same Day Funds equal to its Pro Rata Share of the amount of
the drawing (redenominated into Dollars as provided above, if applicable),
whereupon the Banks shall (subject to subsection 3.3(e)) each be deemed to have
made a Revolving Loan consisting of a Base Rate Loan to the applicable Borrower
in that amount.  The Agent will promptly give notice of the occurrence of any
Reimbursement Date, but failure of the Agent to give any such notice on the
Reimbursement Date or in sufficient time to enable any Bank to effect such
payment on such date shall not relieve such Bank from its obligations under this
Section 3.3.

          (e) With respect to any unreimbursed drawing that is not converted
into Revolving Loans to a Borrower in whole or in part, because of such
Borrower's failure to satisfy the conditions set forth in Section 5.3 or for any
other reason, such Borrower shall be deemed to have incurred from the Issuing
Bank an L/C Borrowing, in Dollars, in the amount of such drawing (determined, in
the case of any Offshore Currency Letter of Credit, as specified below), which
L/C Borrowing shall be due and payable on demand (together with interest) and
shall bear interest at a rate per annum equal to the Base Rate plus 2% per
                                                               ----       
annum.  In such event, each Bank shall upon receipt of any notice pursuant to
subsection 3.3(c) make available to the Agent for the account of the Issuing
Bank an amount in Dollars and in Same Day Funds equal to its Pro Rata Share of
the amount of the drawing.  Each Bank's payment to the Issuing Bank pursuant to
this subsection 3.3(e) shall be deemed payment in respect of its participation
in such L/C Borrowing 

                                      40
<PAGE>
 
and shall constitute an L/C Advance from such Bank in satisfaction of its
participation obligation under this Section 3.3. In the case of any Offshore
Currency Letter of Credit, the unreimbursed drawing shall be redenominated into
Dollars by the Issuing Bank as of the Honor Date, and any payment by each Bank
shall be made in Dollars in an amount equal to such Bank's Pro Rata Share of the
Dollar Equivalent Amount of the unreimbursed drawing as of the Honor Date.

          (f) If any Bank fails to make available to the Agent for the account
of the Issuing Bank the amount of such Bank's Pro Rata Share of the amount of
any drawing by no later than 12:00 noon (San Francisco time) on the
Reimbursement Date, then interest shall accrue on such Bank's obligation to make
                    ----                                                        
such payment, from the Reimbursement Date to the date such Bank makes such
payment, at (i) the Federal Funds Rate in effect from time to time during the
period commencing on the Reimbursement Date and ending on the date three
Business Days thereafter, and (ii) thereafter at the Base Rate as in effect from
time to time.

          (g) Each Bank's obligation in accordance with this Agreement to make
(or participate in) the Revolving Loans, or L/C Advances, as contemplated by
this Section 3.3, as a result of a drawing under a Letter of Credit, shall be
absolute and unconditional and without recourse to the Issuing Bank and shall
not be affected by any circumstance, including (i) any set-off, counterclaim,
recoupment, defense or other right which such Bank may have against the Issuing
Bank, any Loan Party or any other Person for any reason whatsoever; (ii) the
occurrence or continuance of a Default, an Event of Default or a Material
Adverse Effect; or (iii) any other circumstance, happening or event whatsoever,
whether or not similar to any of the foregoing; provided, however, that each
                                                --------  -------           
Bank's obligation to make Revolving Loans under this Section 3.3 is subject to
the conditions set forth in Section 5.3.

          3.4  Repayment of Participations.  (a) Upon (and only upon) receipt by
               ---------------------------                                      
the Agent for the account of the Issuing Bank of funds from a Borrower (i) in
reimbursement of any payment made by the Issuing Bank under the Letter of Credit
with respect to which any Bank has paid the Agent for the account of the Issuing
Bank for such Bank's participation in the Letter of Credit pursuant to Section
3.3 or (ii) in payment of interest thereon, the Agent will pay to each Bank, in
the same funds as those received by the Agent for the account of the Issuing
Bank, the amount of such Bank's Pro Rata Share of such funds, and the Issuing
Bank shall receive the amount of the Pro Rata Share of such funds of any Bank
that did not so pay the Agent for the account of the Issuing Bank.

          (b) If the Agent or the Issuing Bank is required at any time to return
to any Borrower, or to a trustee, receiver, liquidator, custodian, or any
official in any Insolvency Proceeding, any portion of the payments made by such
Borrower to the Agent for the account of the Issuing Bank pursuant to subsection
3.4(a) in reimbursement of a payment made under the Letter of Credit or interest
or fee thereon, each Bank shall, on demand of the Agent, forthwith return to the
Agent or the Issuing Bank the amount of its Pro Rata Share of any amounts so
returned by the Agent or the Issuing Bank plus interest thereon from the date
                                          ----                               
such demand is made to the date such amounts are returned by such Bank to the
Agent or the Issuing Bank, at a rate per annum equal to the Federal Funds Rate
in effect from time to time.

          3.5  Role of the Issuing Bank.  (a) Each Bank and each Borrower agree
               ------------------------                                        
that, in paying any drawing under a Letter of Credit, the Issuing Bank shall not
have any responsibility to obtain any document (other than any sight draft and
certificates expressly required by the Letter of Credit) or to ascertain or
inquire as to the validity or accuracy of any such document or the authority of
the Person executing or delivering any such document.

          (b) No Agent-Related Person nor any of the respective correspondents,
participants or assignees of the Issuing Bank shall be liable to any Bank for:
(i) any action taken or omitted in connection herewith at the request or with
the approval of the Banks (including the Majority Banks, as applicable); (ii)
any action taken or omitted in the absence of gross negligence or willful
misconduct; or (iii) the due execution, effectiveness, validity or
enforceability of any L/C-Related Document.

          (c) Each Borrower hereby assumes all risks of the acts or omissions of
any beneficiary or transferee with respect to its use of any Letter of Credit;
                                                                              
provided, however, that this assumption is not intended to, and shall not,
- --------  -------                                                         
preclude such Borrower's pursuing such rights and remedies as it may have
against the beneficiary or transferee at law or under any other agreement.  No
Agent-Related Person, nor any of the respective correspondents, participants or
assignees of the Issuing Bank, shall be liable or responsible for any of the
matters described in clauses (i) through (vii) of Section 3.6; provided,
                                                               -------- 
however, anything in such clauses to the contrary notwithstanding, that such
- -------                                                                     
Borrower may have a claim against the Issuing Bank, and the Issuing Bank may be
liable to such Borrower, to the extent, but only to the extent, of any direct,
as opposed to consequential or exemplary, damages suffered by such Borrower
which the Company proves were caused by the Issuing Bank's willful misconduct or
gross negligence or the Issuing Bank's willful failure to pay under any Letter
of Credit after the presentation to it by the beneficiary of a sight draft and
certificate(s) strictly complying with the terms and conditions of a Letter of
Credit.  In furtherance and not in limitation of the foregoing:  (i) the Issuing
Bank may accept documents that appear on their face to be in order, without
responsibility for further investigation, regardless of any notice or
information to the contrary; and (ii) the Issuing Bank shall not be responsible
for the validity or sufficiency of any instrument transferring or assigning or
purporting to transfer or assign a Letter of Credit or the rights or benefits
thereunder or proceeds thereof, in whole or in part, which may prove to be
invalid or ineffective for any reason.

          3.6  Obligations Absolute.  The obligations of each Borrower under
               --------------------                                         
this Agreement and any L/C-Related Document to reimburse the Issuing Bank for a
drawing under a Letter of Credit, and to repay any L/C Borrowing and any drawing
under a Letter of Credit converted into Revolving Loans, and the obligations of
each Guarantor hereunder with respect thereto, shall be unconditional and
irrevocable, and shall be paid strictly in accordance with the terms of this
Agreement and each such other L/C-Related Document under all circumstances,
including the following:

           (i) any lack of validity or enforceability of this Agreement or any
     L/C-Related Document;

           (ii) any change in the time, manner or place of payment of, or in any
     other term of, all or any of the obligations of such Borrower in respect of
     any Letter of Credit or any other amendment or waiver of or any consent to
     departure from all or any of the L/C-Related Documents;

                                      42
<PAGE>
 
           (iii)  the existence of any claim, set-off, defense or other right
     that such Borrower may have at any time against any beneficiary or any
     transferee of any Letter of Credit (or any Person for whom any such
     beneficiary or any such transferee may be acting), the Issuing Bank or any
     other Person, whether in connection with this Agreement, the transactions
     contemplated hereby or by the L/C-Related Documents or any unrelated
     transaction;

           (iv) any draft, demand, certificate or other document presented under
     any Letter of Credit proving to be forged, fraudulent, invalid or
     insufficient in any respect or any statement therein being untrue or
     inaccurate in any respect; or any loss or delay in the transmission or
     otherwise of any document required in order to make a drawing under any
     Letter of Credit;

           (v) any payment by the Issuing Bank under any Letter of Credit
     against presentation of a draft or certificate that does not strictly
     comply with the terms of any Letter of Credit; or any payment made by the
     Issuing Bank under any Letter of Credit to any Person purporting to be a
     trustee in bankruptcy, debtor-in-possession, assignee for the benefit of
     creditors, liquidator, receiver or other representative of or successor to
     any beneficiary or any transferee of any Letter of Credit, including any
     arising in connection with any Insolvency Proceeding;

           (vi) any exchange, release or non-perfection of any collateral, or
     any release or amendment or waiver of or consent to departure from any
     other guarantee, for all or any of the obligations of such Borrower in
     respect of any Letter of Credit; or

           (vii)  any other circumstance or happening whatsoever, whether or not
     similar to any of the foregoing, including any other circumstance that
     might otherwise constitute a defense available to, or a discharge of, any
     Borrower or Guarantor.

          3.7  Cash Collateral Pledge.  Upon (i) the request of the Agent, (A)
               ----------------------                                         
if the Issuing Bank has honored any full or partial drawing request on any
Letter of Credit and such drawing has resulted in an L/C Borrowing hereunder, or
(B) if, as of the Revolving Termination Date, any Letters of Credit may for any
reason remain outstanding and partially or wholly undrawn, or (ii) the
occurrence of the circumstances described in Section 2.11 requiring the Company
to Cash Collateralize Letters of Credit, then, the Company shall immediately
Cash Collateralize the L/C Obligations in an amount equal to such L/C
Obligations. In connection with any such amounts to be paid over to the Agent as
cash collateral for Offshore Currency L/C Obligations then outstanding, the
amount of cash collateral to be paid over with respect thereto and held as part
of the cash collateral pursuant to this Section 3.7 shall be determined on the
basis of the Dollar Equivalent Amount thereof as of the most recent Computation
Date.  The Company shall, to the extent necessary, make such additional pledges
from time to time as shall be necessary to ensure that all L/C Obligations
remain at all times fully cash collateralized (in the case of any Offshore
Currency L/C Obligations, the amounts thereof from time to time to be determined
on the basis of the Dollar Equivalent Amount thereof as of the most recent
Computation Date), provided that no such additional pledge shall be required at
                   --------                                                    
any time that the shortfall in the amount of the required cash collateral
results from a change in applicable rates of exchange between Dollars and
Offshore Currencies and such shortfall shall not exceed at such time $100,000.
The

                                      43
<PAGE>
 
Company hereby grants the Agent, for the benefit of the Agent, the Issuing Bank
and the Banks, a security interest in all such cash and deposit account balances
contemplated by this Section 3.7 or Section 9.2.  Cash collateral held under
this Section 3.7 or Section 9.2 shall be maintained in blocked, non-interest
bearing deposit accounts at BofA.

          3.8  Letter of Credit Fees.  (a) The Company shall pay to the Agent
               ---------------------                                         
for the account of each of the Banks a letter of credit fee with respect to the
Letters of Credit equal to the rate per annum equal to the Applicable Fee Amount
of the actual daily maximum amount available to be drawn of the outstanding
Letters of Credit, computed on a quarterly basis in arrears on the last Business
Day of each calendar quarter based upon Letters of Credit outstanding for that
quarter as calculated by the Agent.

          (b) The Company shall pay to the Issuing Bank a letter of credit
fronting fee for each Letter of Credit Issued by the Issuing Bank equal to 0.10%
per annum of the difference between the average daily maximum amount available
to be drawn on the outstanding Letters of Credit and the Pro Rata Share of the
Issuing Bank therein in its capacity as a Bank, computed on a quarterly basis in
arrears on the last Business Day of each calendar quarter based upon Letters of
Credit outstanding for such quarter as calculated by the Agent.

          (c) The letter of credit fees described in subsections 3.8(a) and
3.8(b) shall be due and payable quarterly in arrears on the last Business Day of
each calendar quarter during which Letters of Credit are outstanding, commencing
on the first such quarterly date to occur after the Loan Availability Date,
through the Revolving Termination Date (or such later date upon which the
outstanding Letters of Credit shall expire), with the final payment to be made
on the Revolving Termination Date (or such later expiration date).

          (d) For purposes of determining the average daily maximum amount
available to be drawn on the outstanding Letters of Credit in order to calculate
the fees due under subsection 3.8(a) or subsection (b), the amount of any Letter
of Credit in an Offshore Currency on any date shall be determined based upon the
Dollar Equivalent Amount thereof as of the most recent Computation Date pursuant
to subsection 2.5(a) with respect to such Letter of Credit.

          (e) The Company shall pay to the Issuing Bank from time to time on
demand the normal issuance, presentation, amendment and other processing fees,
and other standard costs and charges, of the Issuing Bank relating to letters of
credit as from time to time in effect, in Dollars or in such Offshore Currency
as the Issuing Bank shall specify.

          3.9  Uniform Customs and Practice.  The Uniform Customs and Practice
               ----------------------------                                   
for Documentary Credits as published by the International Chamber of Commerce
most recently at the time of issuance of any Letter of Credit shall (unless
otherwise expressly provided in the Letters of Credit) apply to the Letters of
Credit.

                                   ARTICLE IV

                     TAXES, YIELD PROTECTION AND ILLEGALITY
                     --------------------------------------

          4.1  Taxes.  (a) Any and all payments by each Loan Party to each Bank
               -----                                                           
or the Agent under this Agreement and any other Loan Document shall be made free
and clear of, and without deduction or withholding for, any Taxes.  In addition,
the Loan Parties shall pay all Other Taxes.

                                      44
<PAGE>
 
          (b) If any Loan Party shall be required by law to deduct or withhold
any Taxes, Other Taxes or Further Taxes from or in respect of any sum payable
hereunder to any Bank or the Agent, then:

          (i) the sum payable shall be increased as necessary so that, after
making all required deductions and withholdings (including deductions and
withholdings applicable to additional sums payable under this Section), such
Bank or the Agent, as the case may be, receives an amount equal to the sum it
would have received had no such deductions or withholdings been made;

           (ii) such Loan Party shall make such deductions and withholdings;

           (iii)  such Loan Party shall pay the full amount deducted or withheld
     to the relevant taxing authority or other authority in accordance with
     applicable law; and

           (iv) such Loan Party shall also pay to each Bank or the Agent for the
     account of such Bank, at the time interest is paid, Further Taxes in the
     amount that the respective Bank specifies as necessary to preserve the
     after-tax yield such Bank would have received if such Taxes, Other Taxes or
     Further Taxes had not been imposed.

          (c) Each Loan Party agrees to indemnify and hold harmless each Bank
and the Agent for the full amount of (i) Taxes, (ii) Other Taxes, and (iii)
Further Taxes in the amount that the respective Bank specifies as necessary to
preserve the after-tax yield such Bank would have received if such Taxes, Other
Taxes or Further Taxes had not been imposed, and any liability (including
penalties, interest, additions to tax and expenses) arising therefrom or with
respect thereto, whether or not such Taxes, Other Taxes or Further Taxes were
correctly or legally asserted.  Payment under this indemnification shall be made
within 30 days after the date such Bank or the Agent makes written demand
therefor; provided, however, that such Loan Party shall not be obligated to make
          --------  -------                                                     
a payment to the Bank or the Agent (as the case may be) pursuant to this Section
in respect of penalties, interest and other liabilities attributable to any
Taxes, Other Taxes, or Further Taxes, if (A) such penalties, interest and other
liabilities have accrued after such Loan Party has indemnified or paid any
additional amount pursuant to this Section, or (B) such penalties, interest and
other liabilities are attributable to the gross negligence or wilful misconduct
of the Bank.  After the Bank or the Agent (as the case may be) learns of the
imposition of Taxes, Other Taxes or Further Taxes, such Bank and the Agent will
act in good faith to promptly notify the relevant Loan Party of its obligations
hereunder.

          (d) Within 30 days after the date of any payment by any Loan Party of
Taxes, Other Taxes or Further Taxes, the Borrowers' Designee shall furnish to
each Bank or the Agent the original or a certified copy of a receipt evidencing
payment thereof, or other evidence of payment satisfactory to such Bank or the
Agent.

          (e) If any Loan Party is required to pay any amount to any Bank or the
Agent pursuant to subsection (b) or (c) of this Section, then such Bank shall
use reasonable efforts (consistent with legal and regulatory restrictions) to
change the jurisdiction of its Lending Office so as to eliminate any such
additional payment by such Loan Party which may thereafter accrue,

                                      45
<PAGE>
 
if such change in the judgment of such Bank is not otherwise materially
disadvantageous to such Bank; provided that the mere existence of fees, charges,
                              --------                                          
costs or expenses that the relevant Loan Party has offered and agreed to pay on
behalf of a Bank shall not be deemed to be disadvantageous to the Bank.

          (f) If a Bank receives a refund in respect of any Taxes, Other Taxes
or Further Taxes as to which it has been indemnified by any Loan Party pursuant
to this Section, or with respect to which any Loan Party has paid additional
amounts pursuant to this Section, it shall within 30 days from the date of
receipt of such refund pay over the amount of such refund (including any
interest paid or credited by the relevant taxing authority with respect to such
refund) to such Loan Party (but only to the extent of indemnity payments made,
or additional amounts paid, by the Loan Party under the Section with respect to
the Taxes, Other Taxes or Further Taxes giving rise to such refund); provided,
                                                                     -------- 
however, that the Loan Party, upon the request of such Bank agrees to repay the
- -------                                                                        
amount paid over to the Loan Party to such Bank in the event such Bank is
required to repay such refund to such relevant authority.

          (g) For any period with respect to which a Bank has failed to provide
the Company, JMII, the applicable Borrower or the Agent with the appropriate
form as required by Section 10.10(a) (whether or not such Bank is lawfully able
to do so, unless such failure is due to a change in treaty, law or regulation
occurring subsequent to the date on which such form originally was required to
be provided), such Bank shall not be entitled to indemnification under this
Section 4.1 with respect to Taxes imposed by the United States (or any political
division thereof); provided that if a Bank, which is otherwise exempt from
                   --------                                               
withholding tax, becomes subject to Taxes because of its failure to deliver a
form required hereunder, the Loan Parties shall take such steps as such Bank
shall reasonably request, at the Bank's expense, to assist such Bank to recover
such Taxes.

          (h) Each Bank and the Agent agrees that it will (i) take all
reasonable actions reasonably requested by the Loan Parties that are without
risk or material cost to such Bank or the Agent (as the case may be) to maintain
all exemptions, available to it from withholding taxes (whether available by
treaty or existing administrative waiver), including the filing of any
certificate or document if such filing would avoid the need for or reduce the
amount of any such additional amounts payable to or for the account of such Bank
or the Agent (as the case may be) pursuant to this Section 4.1, and (ii) to the
extent reasonable and without material cost to it, otherwise cooperate with the
relevant Loan Party to minimize any amount payable by such Loan Party under this
Section.

          4.2  Illegality.  If any Bank determines that the introduction of any
               ----------                                                      
Requirement of Law, or any change in any Requirement of Law, or in the
interpretation or administration of any Requirement of Law, has made it
unlawful, or that any central bank or other Governmental Authority has asserted
that it is unlawful, for any Bank or its applicable Lending Office to make
Offshore Rate Loans, then, in such event, the affected Bank shall give notice
thereof to the Borrowers' Designee (through the Agent).  Thereafter, (i) any
obligation of that Bank to make Offshore Rate Loans (or convert Loans into
Offshore Rate Loans) shall be suspended until such Bank notifies the Agent and
the Borrowers' Designee that the circumstances giving rise to such determination
no longer exist, (ii) to the extent that such determination relates to an
Offshore Rate Loan then being requested by a Borrower pursuant to a Notice of
Borrowing or a Notice of Conversion/Continuation, such Bank shall make such Loan
as (or convert such Loan to) a Base Rate Loan, and (iii) any outstanding
Offshore Rate Loans of such affected Bank shall convert 

                                      46
<PAGE>
 
into Base Rate Loans either on the last day of the Interest Period thereof, if
such Bank may lawfully continue to maintain such Offshore Rate Loans to such
day, or (subject to Section 4.4) immediately, if such Bank may not lawfully
continue to maintain such Offshore Rate Loan. If such notice relates to an
Offshore Currency Loan, such Loan to be made as (or converted into) a Base Rate
Loan by the affected Bank shall be in the Dollar Equivalent Amount of the
Offshore Currency Loan maintained by such Bank, or to be made, converted or
continued by such Bank.

          4.3  Increased Costs and Reduction of Return.  (a) If any Bank
               ---------------------------------------                  
determines that, due to either (i) the introduction after the date hereof of or
any change after the date hereof in or in the interpretation of any law or
regulation or (ii) the compliance by that Bank with any guideline or request
from any central bank or other Governmental Authority (whether or not having the
force of law), there shall be any increase in the cost to such Bank of agreeing
to make or making, funding or maintaining any Offshore Rate Loans or
participating in Letters of Credit, or, in the case of the Issuing Bank, any
increase in the cost to the Issuing Bank of agreeing to issue, issuing or
maintaining any Letter of Credit or of agreeing to make or making, funding or
maintaining any unpaid drawing under any Letter of Credit, then such Bank shall
promptly give notice to the Borrowers' Designee and the affected Borrower shall
pay to such Bank, within 15 days of receipt of the notice referred to above,
such additional amounts (in the form of an increased rate of, or a different
method of calculating, interest or otherwise as such Bank in its sole discretion
shall determine) as shall be required to compensate such Bank for such increased
costs or reductions in amounts received or receivable hereunder.  To the extent
the notice required by the preceding sentence and relating to the costs arising
under this Section 4.3 is given by any Bank more than 90 days after the
occurrence of the event giving rise to the additional costs of the type
described in this Section 4.3, such Bank shall not be entitled to compensation
under this Section 4.3 for any amounts incurred or accrued prior to the giving
of such notice to the Borrowers' Designee.

          (b) If any Bank shall have determined that (i) the introduction after
the date hereof of any Capital Adequacy Regulation, (ii) any change after the
date hereof in any Capital Adequacy Regulation, or (iii) any change after the
date hereof in the interpretation or administration of any Capital Adequacy
Regulation by any central bank or other Governmental Authority charged with the
interpretation or administration thereof, affects or would affect the amount of
capital required or expected to be maintained by such Bank or any corporation
controlling such Bank and (taking into consideration such Bank's or such
corporation's policies with respect to capital adequacy and such Bank's desired
return on capital) determines that the amount of such capital is increased as a
consequence of its Commitment, loans, credits or obligations under this
Agreement, the Company agrees to pay such Bank, within 15 days of the receipt of
the notice referred to below, such additional amounts as shall be required to
compensate such Bank for the increased cost to such Bank as a result of such
increase of capital.  In determining such additional amounts, each Bank will act
reasonably and in good faith and will use averaging and attribution methods
which are reasonable, provided that such Bank's determination of compensation
                      --------                                               
under this subsection 4.3(b) shall, absent manifest error, be final and
conclusive and binding on all parties hereto.  Each Bank, upon determining that
additional amounts will be payable pursuant to this subsection 4.3(b), will give
prompt written notice thereof to the Borrowers' Designee, although the failure
to give any such notice shall not release or diminish the Company's obligations
to pay additional amounts pursuant to this subsection 4.3(b).  To the extent the
notice required by the immediately preceding sentence is given by any

                                      47
<PAGE>
 
Bank more than 90 days after the occurrence of the event giving rise to the
additional costs of the type described in this subsection 4.3(b), such Bank
shall not be entitled to compensation under this subsection 4.3(b) for any
amounts incurred or accrued prior to the giving of such notice to the Borrowers'
Designee.

          4.4  Funding Losses.  Each Borrower shall reimburse each Bank and hold
               --------------                                                   
each Bank harmless, within 15 days of written request by such Bank to the
Borrowers' Designee (which request shall set forth in reasonable detail the
basis for requesting and the calculation of the amount of such compensation),
from any loss or expense which the Bank may sustain or incur as a consequence
of:

           (a) the failure of such Borrower to make on a timely basis any
payment of principal of any Offshore Rate Loan;

          (b) the failure of such Borrower to borrow, continue or convert a Loan
after the Borrowers' Designee has given (or is deemed to have given) a Notice of
Borrowing or a Notice of Conversion/Continuation;

          (c) the failure of such Borrower to make any prepayment in accordance
with any notice delivered under Section 2.9 or 2.10;

          (d) the prepayment (including pursuant to Section 2.10, 2.11, or 4.8)
or other payment (including after acceleration thereof) of an Offshore Rate Loan
on a day that is not the last day of the relevant Interest Period; or

          (e) the conversion under Section 2.4 of any Offshore Rate Loan to a
Base Rate Loan on a day that is not the last day of the relevant Interest
Period;

including any such loss or expense arising from the liquidation or reemployment
of funds obtained by it to maintain its Offshore Rate Loans or from fees payable
to terminate the deposits from which such funds were obtained or from charges
relating to any Offshore Currency Loans (but excluding any loss of anticipated
profits).

          4.5  Inability to Determine Rates.  If the Agent or the Banks shall
               ----------------------------                                  
determine that for any reason adequate and reasonable means do not exist for
determining the Offshore Rate for any requested Interest Period with respect to
a proposed borrowing of Offshore Rate Loans or conversion or continuation of
Offshore Rate Loans, or that the Offshore Rate applicable pursuant hereto for
any requested Interest Period with respect to a proposed borrowing of Offshore
Rate Loans, or a conversion into or continuation of Offshore Rate Loans does not
adequately and fairly reflect the cost to the Banks of funding such Loans, the
Agent will promptly so notify the Borrowers' Designee and each Bank.
Thereafter, the obligation of the Banks to make or maintain Offshore Rate Loans
hereunder shall be suspended until the Agent upon the instructions of the Banks
revokes such notice in writing.  Upon receipt of such notice, the Borrowers'
Designee may revoke any Notice of Borrowing or Notice of Conversion/Continuation
then submitted by it.  In the case of any Offshore Rate Loans in Dollars, if the
Borrowers' Designee does not revoke such Notice, the Banks shall make, convert
or continue the Loans, as proposed by the Borrowers' Designee, in the amount
specified in the applicable notice submitted by the Borrowers' Designee, but
such Loans shall be made, converted or continued as Base Rate Loans instead of
Offshore Rate Loans.  In the case of any Offshore Currency Loans, the Borrowing
or continuation shall be 

                                      48
<PAGE>
 
in an aggregate amount equal to the Dollar Equivalent Amount of the originally
requested Borrowing or continuation in the Offshore Currency, and to that end
any outstanding Offshore Currency Loans which are the subject of any
continuation shall be redenominated and converted into Base Rate Loans in
Dollars with effect from the last day of the Interest Period with respect to any
such Offshore Currency Loans.

          4.6  Reserves on Offshore Rate Loans.  The Company shall pay to each
               -------------------------------                                
Bank, as long as such Bank shall be required under regulations of the FRB to
maintain reserves with respect to liabilities or assets consisting of or
including Eurocurrency funds or deposits (currently known as "Eurocurrency
liabilities"), and, in respect of any Offshore Currency Loans, under any
applicable regulations of the central bank or other relevant Governmental
Authority in the country in which the Offshore Currency of such Offshore Rate
Loan circulates, additional costs on the unpaid principal amount of each
Offshore Rate Loan equal to the actual costs of such reserves allocated to such
Loan by the Bank (as determined by such Bank in good faith, which determination
shall be conclusive), payable on each date on which interest is payable on such
Loan, provided such Bank shall promptly give notice to the Borrowers' Designee
      --------                                                                
and to the Agent of such additional cost.  Thereafter the affected Borrower
shall pay such Bank, within 15 days of receipt of such notice, such additional
amounts (in the form of an increased rate of, or a different method of
calculating, interest or otherwise as such Bank in its sole discretion shall
determine) as shall be required to compensate such Bank for such increased
costs.  To the extent the notice required by the preceding sentence and relating
to the costs arising under this Section 4.6 is given by any Bank more than 90
days after the occurrence of the event giving rise to the additional costs of
the type described in this Section 4.6, such Bank shall not be entitled to
compensation under this Section 4.6 for any amounts incurred or accrued prior to
the giving of such notice to the Borrowers' Designee.

          4.7  Certificates of Banks.  Any Bank claiming reimbursement or
               ---------------------                                     
compensation under this Article IV shall deliver to the Borrowers' Designee
(with a copy to the Agent) a certificate setting forth in reasonable detail the
amount payable to the Bank hereunder and such certificate shall be conclusive

rise to the operation of Section 4.1, 4.2, 4.3 or 4.6 with respect to any Bank
which results in such Bank (an "Affected Bank") charging to any Borrower
                                -------------

other Banks, or upon notice to the Agent from any Bank that it shall not consent
to a request by the Borrowers' Designee for an extension of the Revolving
Termination Date pursuant to subsection 2.12(b), the Borrowers' Designee may:
(i) request one or more of the other Banks to acquire and assume all or part of
such Affected Bank's Loans and Commitment; or (ii) designate a replacement
commercial bank, which shall be an Eligible Assignee, satisfactory to the
Borrowers' Designee to acquire and assume all or a ratable part of such Affected
Bank's Loans and Commitment (a "Replacement Bank"); provided, however, that the
                                ----------------    --------  -------          
Borrowers shall be liable for the payment upon demand of all costs and other
amounts arising under Section 4.4 hereof that result from the acquisition of any
Affected Bank's Loan and/or Commitment (or any portion thereof) by a Bank or
Replacement Bank, as the case may be, on a date other than the last day of the
applicable Interest Period with respect to any Offshore Rate Loan then
outstanding.  Any such designation of a Replacement Bank under clause (ii) shall
be

                                      49

assignment provisions contained in Section 11.8 hereof, and shall in any event
be subject to the prior written consent of the Agent, the Issuing Bank and the
Swingline Bank (which consents shall not be unreasonably withheld).

               ------------------------                               
occurrence of any event giving rise to the operations of Section 4.1, 4.2, 4.3
or 4.6 with respect to such Bank it will, if requested by the Borrowers'
Designee, use reasonable efforts (subject to overall policy considerations of
such Bank) to designate another lending office for any Loans or Letters of
Credit affected by such event, provided that such designation is made on such
                               --------                                      
terms that such Bank and its Lending Office suffer no material economic, legal
or regulatory disadvantage, with the object of avoiding the consequence of the
event giving rise to the operation of such Section.

          4.10  Survival.  The agreements and obligations of the Company and the
                --------                                                        
other Loan Parties in this Article IV shall survive the termination of the

standing under the laws of each jurisdiction where its ownership, lease or
operation of property or the conduct of its business requires such
qualification, license or good standing except, in each case referred to in

do so would not reasonably be expected to have a Material Adverse Effect.

          6.2  Authorization; No Contravention.  The execution, delivery and
               -------------------------------

Requirement of Law, except where such violation would not reasonably be expected
to have a Material Adverse Effect.

          6.3  Governmental Authorization.  No approval, consent, exemption,
               --------------------------

          6.4  Binding Effect.  This Agreement and each other Loan Document to
               --------------                                                 
which any Loan Party is a party constitute the legal, valid and binding
obligations of such Loan Party, enforceable against such Loan Party in
accordance with their respective terms, except to the extent that the
enforceability thereof may be limited by applicable bankruptcy, insolvency,
reorganization, moratorium or other similar laws affecting creditors' rights

          6.5  Litigation.  Except as disclosed in the Company's Form 10-K with
               ----------                                                      
respect to its fiscal year ended December 31, 1997, there are no actions, suits,
proceedings (regardless of whether enforcement is sought in equity or at law),

Authority, against the Company, or any of its Material Subsidiaries or any of
their respective properties, (a) which in any manner draws into question the
validity or enforceability of any Loan Document; or (b) in which there is a
reasonable possibility of any adverse decision that would have a Material
Adverse Effect.  No injunction, writ, temporary restraining order or any order

therein provided.

          6.6  No Defaults.  No Default or Event of Default exists or would
               -----------

applicable provisions of ERISA, the Code and other federal or state law.  Each
Pension Plan which is intended to qualify under Section 401(a) of the Code has
received a favorable determination letter from the IRS and, to the best
knowledge of the Company, nothing has occurred which would cause the loss of
such qualification.  The Company and each ERISA Affiliate has made all required
contributions to any Pension Plan subject to Section 412 of the Code, and no
application for a funding waiver or an extension of any amortization period
pursuant to Section 412 of the Code has been made with respect to any Pension

neither the Company nor any ERISA Affiliate has incurred, or reasonably expects
to incur, any liability (and no event has occurred which, with the giving of

                                      53

notice under Section 4219 of ERISA, would result in such liability) under
Section 4201 or 4243 of ERISA with respect to a Multiemployer Plan; and (v)
neither the Company nor any ERISA Affiliate has engaged in a transaction that
could be subject to Section 4069 or 4212(c) of ERISA.

          6.8  Use of Proceeds; Margin Regulations.  The proceeds of the Loans
               -----------------------------------                            
are to be used solely for the purposes set forth in and permitted by Section
7.10 and Section 8.6.  Neither the Company nor any of its Subsidiaries is
generally engaged in the business of purchasing or selling Margin Stock or
extending credit for the purpose of purchasing or carrying Margin Stock.

          6.9  Title to Properties; Liens.  The Company and each of its Material

leasehold interests in (or the equivalent in the applicable jurisdiction), all
real property necessary or used in the ordinary conduct of their respective
businesses, except for any Permitted Liens and such defects in or other

in the aggregate, reasonably be expected to have a Material Adverse Effect.

          6.10  Taxes.  The Company and its Subsidiaries have filed all Federal
                -----                                                          
and other material tax returns and reports required to be filed, and have paid
all Federal and other material taxes, assessments, fees and other governmental
charges levied or imposed upon them or their properties, income or assets
otherwise due and payable, (i) except those which are being contested in good
faith by appropriate proceedings or (ii) where the failure to so file or pay

          6.11  Financial Condition.  (a) The audited consolidated balance sheet
                -------------------

conducts in the ordinary course of business a review of the effect of existing
Environmental Laws and existing Environmental Claims on the business, operations
and properties of the Company and its Subsidiaries, and as a result thereof the
Company has reasonably concluded that such Environmental Laws and Environmental
Claims would not, individually or in the aggregate, reasonably be expected to
have a Material Adverse Effect.

          6.13  Regulated Entities.  None of the Company or any Subsidiary of
                ------------------

Company Act of 1940.  No Borrower is subject to regulation under the Public
Utility Holding Company Act of 1935, the Federal Power Act, the Interstate
Commerce Act, any state public utilities code, or any other Federal or state
statute or regulation limiting its ability to incur Indebtedness.

          6.14  Copyrights, Patents, Trademarks and Licenses, Etc.  The Company
                -------------------------------------------------              
and its Subsidiaries own or are licensed or otherwise have the right to use all
of the patents, trademarks, service marks, trade names, copyrights, contractual
franchises, authorizations and other rights that are reasonably necessary for
the operation of their respective businesses, without any known conflict with
the rights of any other Person, except where the failure to so own, license or
otherwise have the right to use any of the foregoing would not, alone or in the
aggregate, be reasonably expected to have a Material Adverse Effect.  To the
best knowledge of the Company, (i) no product, process, method, substance, part
or other material now employed, or now contemplated to be employed, by the
Company or any Subsidiary infringes upon any rights held by any other Person,
(ii) except as specifically disclosed in the Company's Form 10-K for the fiscal
year ended December 31, 1997, no claim or litigation regarding any of the
foregoing is pending or, to the best knowledge of the Company, threatened, and
(iii) no patent, invention, device, application, principle or any statute, law,
rule, regulation, standard or code is pending or, to the best knowledge of the
Company, proposed, which, in any such case, would reasonably be expected to have
a Material Adverse Effect described in clauses (i), (ii) or (iii).

          6.15  Insurance.  The properties of the Company and its Material
                ---------                                                 
Subsidiaries are insured, with financially sound and reputable insurance
companies or through the Company's own program of self-insurance, in such
amounts, with such deductibles and covering such risks as are customary for
companies engaged in similar businesses and owning similar properties in
localities where the Company or such Subsidiary operates.

          6.16  Full Disclosure.  The factual information (other than any
                ---------------                                          
projections or pro forma financial information) included in any exhibits,
reports, statements or certificates furnished by or on behalf of the Company or
any of its Subsidiaries in connection with the Loan Documents (including the
offering and disclosure materials delivered by or on behalf of the Company to
the Banks prior to the Closing Date) concerning the operations, business,
financial conditions, properties and prospects of the Company and its
Subsidiaries is, taken as a whole, true and correct in all material respects as
of the date such information was supplied to the Agent and the Banks and, taken
as a whole, does not omit any material fact required to be stated or necessary
to make any statements made, in light of the circumstances under which they are
made, not misleading.  All projections and pro forma financial information are
based on good faith assumptions and estimates that the Company believed
reasonable at the time made.  However, because financial projections are based
on estimates and assumptions about circumstances and events that have not yet
taken place, actual results during the period covered by such projections may
differ materially from the projected results.

          6.17  Year 2000.  The Company has reviewed the areas within its
                ---------                                                
consolidated business and operations that could be adversely affected by, and
has developed or is developing a plan to address on a timely basis, the "Year
2000 Problem" (that is, the risk that computer applications used by the Company
and its Subsidiaries may be unable to recognize and perform properly date-
sensitive functions involving certain dates prior to and any date after December
31, 1999).  Based on such review and plan, the Company reasonably believes that
the "Year 2000 Problem" will not have a Material Adverse Effect.

to perform or observe any term, covenant or agreement in its Guaranty; or the
Guaranty of any Guarantor is for any reason partially (including with respect to
future advances) or wholly revoked or invalidated, or otherwise ceases to be in
full force and effect, or any Guarantor or any other Person contests in any
manner the validity or enforceability thereof or denies that it has any further
liability or obligation thereunder.

          9.2  Remedies.  If any Event of Default occurs, the Agent shall, at
               --------                                                      
the request of, or may, with the consent of, the Majority Banks, do any or all
of the following:

          (a) declare the obligation of each Bank to make any Loans hereunder
and any obligation of the Issuing Bank to Issue any Letters of Credit hereunder
to be terminated, whereupon such obligations and each Bank's Commitment, the
Swingline Commitment and the L/C Commitment shall be terminated;

          (b) declare an amount equal to the maximum aggregate amount that is or
at any time thereafter may become available for drawing under any outstanding
Letters of Credit (whether or not any beneficiary shall have presented, or shall
be entitled at such time to present, the drafts or other documents required to
draw under such Letters of Credit) to be immediately due and payable, which
amount shall be held by the Agent as security for the Company's reimbursement
obligations for drawings that may subsequently occur under outstanding Letters
of Credit, and declare the unpaid principal amount of all outstanding Loans, all
interest accrued and unpaid thereon, and all other amounts owing or payable
hereunder or under any other Loan Document to be immediately due and payable,
without presentment, demand, protest or other notice of any kind, all of which
are hereby expressly waived by the Borrowers; and

                                   THE AGENT
                                   ---------

          10.1  Appointment and Authorization; "Agent".  (a) Each Bank hereby
                --------------------------------------                       
irrevocably (subject to Section 10.9) appoints, designates and authorizes the
Agent to take such action on its behalf under the provisions of this Agreement
and each other Loan Document and to exercise such powers and perform such duties
as are expressly delegated to it by the terms of this Agreement or any other
Loan Document, together with such powers as are reasonably incidental thereto.
Notwithstanding any provision to the contrary contained elsewhere in this
Agreement or in any other Loan Document, the Agent shall not have any duties or
responsibilities, except those expressly set forth herein, nor shall the Agent
have or be deemed to have any fiduciary relationship with any Bank, and no
implied covenants, functions, responsibilities, duties, obligations or
liabilities shall be read into this Agreement or any other Loan Document or
otherwise exist against the Agent.  Without limiting the generality of the
foregoing sentence, the use of the term "agent" in this Agreement with reference
to the Agent is not intended to connote any fiduciary or other implied (or
express) obligations arising under agency doctrine of any applicable law.
Instead, such term is used merely as a matter of market custom, and is intended
to create or reflect only an administrative relationship between independent
contracting parties.

          (b) The Issuing Bank shall act on behalf of the Banks with respect to
any Letters of Credit Issued by it and the documents associated therewith until
such time and except for so long as the Agent may agree at the request of the
Majority Banks to act for such Issuing Bank with respect thereto; provided,
                                                                  -------- 
however, that the Issuing Bank shall have all of the benefits and immunities (i)
- -------                                                                         
provided to the Agent in this Article X with respect to any acts taken or
omissions suffered by the Issuing Bank in connection with Letters of Credit
Issued by it or proposed to be Issued by it and the application and agreements
for letters of credit pertaining to the Letters of Credit as fully as if the
term "Agent", as used in this Article X, included the Issuing Bank with respect
to such acts or omissions, and (ii) as additionally provided in this Agreement
with respect to the Issuing Bank.

          10.2  Delegation of Duties.  The Agent may execute any of its duties
                --------------------                                          
under this Agreement or any other Loan Document by or through agents, employees
or attorneys-in-fact and shall be entitled to advice of counsel concerning all
matters pertaining to such duties.  The Agent shall not be responsible for the
negligence or misconduct of any agent or attorney-in-fact that it selects with
reasonable care.

          10.3  Liability of Agent.  None of the Agent-Related Persons shall (i)
                ------------------                                              
be liable for any action taken or omitted to be taken by any of them under or in
connection with this Agreement or any other Loan Document or the transactions
contemplated hereby (except for its own gross negligence or willful misconduct),
or (ii) be responsible in any manner to any of the Banks for any recital,
statement, representation or warranty made by the Company, any other Loan Party,
the Borrowers' Designee or any Subsidiary or Affiliate of the Company, or any
officer thereof, contained in this Agreement or in any other Loan Document, or
in any certificate, report, statement or other document referred to or provided
for in, or received by the Agent under or in connection with, this Agreement or
any other Loan Document, or the validity, effectiveness, genuineness,
enforceability or sufficiency of this Agreement or any other Loan Document, or
for any failure of the Company, any other Borrower or any other party to any
Loan Document to perform its obligations hereunder or thereunder.  No Agent-
Related Person shall be under any 

                                      70
<PAGE>
 
obligation to any Bank to ascertain or to inquire as to the observance or
performance of any of the agreements contained in, or conditions of, this
Agreement or any other Loan Document, or to inspect the properties, books or
records of the Company, any other Borrower or any of the Company's Subsidiaries
or Affiliates.

          10.4  Reliance by Agent.  (a) The Agent shall be entitled to rely, and
                -----------------                                               
shall be fully protected in relying, upon any writing, resolution, notice,
consent, certificate, affidavit, letter, telegram, facsimile, telex or telephone
message, statement or other document or conversation believed by it to be
genuine and correct and to have been signed, sent or made by the proper Person
or Persons, and upon advice and statements of legal counsel (including counsel
to the Company or any Loan Party), independent accountants and other experts
selected by the Agent. The Agent shall be fully justified in failing or refusing
to take any action under this Agreement or any other Loan Document unless it
shall first receive such advice or concurrence of the Majority Banks as it deems
appropriate and, if it so requests, it shall first be indemnified to its
satisfaction by the Banks against any and all liability and expense which may be
incurred by it by reason of taking or continuing to take any such action.  The
Agent shall in all cases be fully protected in acting, or in refraining from
acting, under this Agreement or any other Loan Document in accordance with a
request or consent of the Majority Banks and such request and any action taken
or failure to act pursuant thereto shall be binding upon all of the Banks.

          (b) For purposes of determining compliance with the conditions
specified in Section 5.1, each Bank that has executed this Agreement shall be
deemed to have consented to, approved or accepted or to be satisfied with, each
document or other matter either sent (or made available) by the Agent to such
Bank for consent, approval, acceptance or satisfaction, or required thereunder
to be consented to or approved by or acceptable or satisfactory to such Bank.

          10.5  Notice of Default.  The Agent shall not be deemed to have
                -----------------                                        
knowledge or notice of the occurrence of any Default or Event of Default, except
with respect to defaults in the payment of principal, interest and fees required
to be paid to the Agent for the account of the Banks, unless the Agent shall
have received written notice from a Bank, the Borrowers' Designee or any other
Loan Party referring to this Agreement, describing such Default or Event of
Default and stating that such notice is a "notice of default".  The Agent will
notify the Banks of its receipt of any such notice.  The Agent shall take such
action with respect to such Default or Event of Default as may be requested by
the Majority Banks in accordance with Article IX; provided, however, that unless
                                                  --------  -------             
and until the Agent has received any such request, the Agent may (but shall not
be obligated to) take such action, or refrain from taking such action, with
respect to such Default or Event of Default as it shall deem advisable or in the
best interest of the Banks.

          10.6  Credit Decision.  Each Bank acknowledges that none of the Agent-
                ---------------                                                
Related Persons has made any representation or warranty to it, and that no act
by the Agent hereinafter taken, including any review of the affairs of the
Company and its Subsidiaries, shall be deemed to constitute any representation
or warranty by any Agent-Related Person to any Bank.  Each Bank represents to
the Agent that it has, independently and without reliance upon any Agent-Related
Person and based on such documents and information as it has deemed appropriate,
made its own appraisal of and investigation into the business, prospects,
operations, property, financial and other condition and creditworthiness of the
Company and its Subsidiaries, and all applicable bank regulatory laws relating
to the transactions contemplated hereby, and made its own decision to enter into
this Agreement and to extend credit to each Borrower hereunder.  Each Bank also
represents that it will, independently and without reliance upon any Agent-

                                      71
<PAGE>
 
Related Person and based on such documents and information as it shall deem
appropriate at the time, continue to make its own credit analysis, appraisals
and decisions in taking or not taking action under this Agreement and the other
Loan Documents, and to make such investigations as it deems necessary to inform
itself as to the business, prospects, operations, property, financial and other
condition and creditworthiness of each Borrower.  Unless otherwise provided in
this Agreement, the Agent will forward to all of the Banks copies of all
financial statements, notices, reports and other documents required to be
furnished to the Agent hereunder by any Loan Party which are not by the terms
hereof required to be distributed by such Loan Party directly to the Banks.
Except for any financial statements, notices, reports and other documents
expressly herein required to be furnished to the Banks by the Agent, the Agent
shall not have any duty or responsibility to provide any Bank with any credit or
other information concerning the business, prospects, operations, property,
financial and other condition or creditworthiness of the Company or any
Subsidiary which may come into the possession of any of the Agent-Related
Persons.

          10.7  Indemnification of Agent.  Whether or not the transactions
                ------------------------                                  
contemplated hereby are consummated, the Banks shall indemnify upon demand the
Agent-Related Persons (to the extent not reimbursed by or on behalf of the
Borrowers and without limiting the obligation of the Borrowers to do so), in
accordance with the Banks' Pro Rata Shares, from and against any and all
Indemnified Liabilities; provided, however, that no Bank shall be liable for the
                         --------  -------                                      
payment to the Agent-Related Persons of any portion of such Indemnified
Liabilities to the extent they are found by a final decision of a court of
competent jurisdiction to have resulted from such Person's gross negligence or
willful misconduct.  Without limitation of the foregoing, each Bank shall
reimburse the Agent upon demand for its ratable share of any costs or out-of-
pocket expenses (including Attorney Costs) incurred by the Agent in connection
with the preparation, execution, delivery, administration, modification,
amendment or enforcement (whether through negotiations, legal proceedings or
otherwise) of, or legal advice in respect of rights or responsibilities under,
this Agreement, any other Loan Document, or any document contemplated by or
referred to herein, to the extent that the Agent is not reimbursed for such
expenses by or on behalf of the Company or any other Loan Party.  The
undertaking in this Section shall survive the termination of the Commitments,
the termination or expiration of all Letters of Credit, the payment of all other
Obligations hereunder and the resignation or replacement of the Agent.

          10.8  Agent in Individual Capacity.  BofA and its Affiliates may make
                ----------------------------                                   
loans to, issue letters of credit for the account of, accept deposits from,
acquire equity interests in and generally engage in any kind of banking, trust,
financial advisory, underwriting or other business with the Company and its
Subsidiaries and Affiliates as though BofA were not the Agent or the Issuing
Bank hereunder and without notice to or consent of the Banks.  The Banks
acknowledge that, pursuant to such activities, BofA or its Affiliates may
receive information regarding the Company or its Subsidiaries or Affiliates
(including information that may be subject to confidentiality obligations in
favor of the Company or such Subsidiary or Affiliate) and acknowledge that the
Agent shall be under no obligation to provide such information to them.  With
respect to its Loans, BofA shall have the same rights and powers under this
Agreement as any other Bank and may exercise the same as though it were not the
Agent or the Issuing Bank.

          10.9  Successor Agent.  The Agent may, and at the request of the
                ---------------                                           
Majority Banks shall, resign as Agent upon 30 days' notice to the Banks.  If the
Agent resigns under this Agreement, the Majority Banks, after consulting with
and giving due regard to the suggestions of the Company, shall appoint from
among the Banks a successor agent for the Banks which successor agent shall be
approved by the Borrowers' Designee (such approval not to be unreasonably

                                      72
<PAGE>
 
withheld).  If no successor agent is appointed prior to the effective date of
the resignation of the Agent, the Agent may appoint, after consulting with the
Banks and the Borrowers' Designee, a successor agent from among the Banks.  Upon
the acceptance of its appointment as successor agent hereunder, such successor
agent shall succeed to all the rights, powers and duties of the retiring Agent
and the term "Agent" shall mean such successor agent and the retiring Agent's
appointment, powers and duties as Agent shall be terminated. After any retiring
Agent's resignation hereunder as Agent, the provisions of this Article X and
Sections 11.4 and 11.5 shall inure to its benefit as to any actions taken or
omitted to be taken by it while it was Agent under this Agreement.  If no
successor agent has accepted appointment as Agent by the date which is 30 days
following a retiring Agent's notice of resignation, the retiring Agent's
resignation shall nevertheless thereupon become effective and the Banks shall
perform all of the duties of the Agent hereunder until such time, if any, as the
Majority Banks appoint a successor agent as provided for above.  Notwithstanding
the foregoing, however, BofA may not be removed as the Agent at the request of
the Majority Banks unless BofA shall also simultaneously be replaced as "Issuing
Bank" and "Swingline Bank" hereunder pursuant to documentation in form and
substance reasonably satisfactory to BofA.

          10.10  Withholding Tax.  (a) With respect to any Loan to the Company,
                 ---------------                                               
JMII or any Additional Borrower that is organized in the United States, any Bank
that is a "foreign corporation" within the meaning of the Code shall deliver to
the Agent and the Borrowers' Designee on or prior to the date of its execution
and delivery of this Agreement in the case of each Bank listed on the signature
pages hereof and on or prior to the date on which it becomes a Bank in the case
of each other Bank, before the payment of any interest or fees in each third
succeeding calendar year during which interest or fees may be paid under this
Agreement or before such form expires or becomes obsolete:

           (i) two properly completed and executed copies of IRS Form 1001 (or
     successor form), certifying that such Bank is entitled to benefits under an
     income tax treaty to which the United States is a party which completely
     exempts the Bank from United States withholding tax on payments of interest
     for the account of such Bank under this Agreement or the Notes;

           (ii) two properly completed and executed copies of IRS Form 4224 (or
     successor form), certifying that income receivable by such Bank pursuant to
     this Agreement or the Notes is effectively connected with the conduct of
     such Bank's trade or business in the United States and such income is
     completely exempt from United States withholding tax; or

           (iii)  such other form or forms as may be required under the Code or
     other laws of the United States as a condition to complete exemption from
     United States withholding tax with respect to any interest payment
     hereunder or under the Notes;

Such Bank agrees to promptly notify the Agent of any change in circumstances
which would modify or render invalid any claimed exemption.

          (b) If any Bank claims exemption from withholding tax under a United
States tax treaty by providing IRS Form 1001 (or successor form) and such Bank
sells, assigns, grants a participation in, or otherwise transfers all or part of
the Obligations of any Borrower owing to such Bank, such Bank agrees to notify
the Agent of the percentage amount in which it is no 

                                      73
<PAGE>
 
longer the beneficial owner of Obligations of such Borrower owing to such Bank.
To the extent of such percentage amount, the Agent will treat such Bank's IRS
Form 1001 (or successor form) as no longer valid.

          (c) If any Bank claiming exemption from United States withholding tax
by filing IRS Form 4224 (or successor form) with the Agent sells, assigns,
grants a participation in, or otherwise transfers all or part of the Obligations
of any Borrower owing to such Bank, such Bank agrees to undertake sole
responsibility for complying with the withholding tax requirements imposed by
Sections 1441 and 1442 of the Code.

          (d) If the forms or other documentation required by subsection (a) of
this Section are not timely delivered to the Agent, then the Agent may withhold
from any interest payment to such Bank not providing such forms or other
documentation an amount equivalent to the applicable withholding tax imposed by
Sections 1441 and 1442 of the Code, without reduction.

          (e) If the IRS or any other Governmental Authority of the United
States or other jurisdiction asserts a claim that the Agent did not properly
withhold tax from amounts paid to or for the account of any Bank (because the
appropriate form was not delivered or was not properly executed, or because such
Bank failed to notify the Agent of a change in circumstances which rendered the
exemption from withholding tax ineffective, or for any other reason) such Bank
shall indemnify the Agent fully for all amounts paid, directly or indirectly, by
the Agent as tax or otherwise, including penalties and interest, and including
any taxes imposed by any jurisdiction on the amounts payable to the Agent under
this Section, together with all costs and expenses (including Attorney Costs).
The obligation of the Banks under this subsection shall survive the termination
of the Commitments, the termination or expiration of all Letters of Credit, the
payment of all other Obligations hereunder and the resignation or replacement of
the Agent.

          10.11  Co-Agents; Lead Managers.  None of the Banks identified on the
                 ------------------------                                      
facing page or signature pages of this Agreement as a "co-agent," "syndication
agent," or "lead manager" shall have any right, power, obligation, liability,
responsibility or duty under this Agreement other than those applicable to all
Banks as such.  Without limiting the foregoing, none of the Banks so identified
as a "co-agent," "syndication agent," or "lead manager" shall have or be deemed
to have any fiduciary relationship with any Bank.  Each Bank acknowledges that
it has not relied, and will not rely, on any of the Banks so identified in
deciding to enter into this Agreement or in taking or not taking action
hereunder.

and the Banks to receive written confirmation of any telephonic notice or the
receipt by the Agent and the Banks of a confirmation which is at variance with
the terms understood by the Agent and the Banks to be contained in the
telephonic or facsimile notice.

power or privilege hereunder, shall operate as a waiver thereof;  nor shall any
single or partial exercise of any right, remedy, power or privilege hereunder
preclude any other or further exercise thereof or the exercise of any other
right, remedy, power or privilege.  The rights provided for in this Agreement
and the other Loan Documents are cumulative and are not exclusive of any other
rights, powers, privileges or remedies provided by law or in equity, or under
any other instrument, document or agreement now existing or hereafter arising.

under this Agreement or any other Loan Document during the existence of an Event
of Default or after acceleration of the Loans (including in connection with any
"workout" or restructuring regarding the Loans, and including in any Insolvency
Proceeding or appellate proceeding).

          11.5  Indemnification.  Whether or not the transactions contemplated
                ---------------

obligations, losses, damages, penalties, actions, judgments, suits, costs,
charges, expenses and disbursements (including reasonable Attorney Costs) of any
kind or nature whatsoever which may at any time (including at any time following

termination, resignation or replacement of the Agent or replacement of any Bank)
be imposed on, incurred by or asserted against any such Person in connection
with any investigation, litigation or proceeding (including any Insolvency
Proceeding or appellate proceeding) in any way relating to or arising out of
this Agreement or any document contemplated by or referred to herein, or the
transactions contemplated hereby or the use of the Proceeds of any Loans, or any
action taken or omitted by any such Person under or in connection with any of
the foregoing, whether or not any Indemnified Person is a party thereto (all the
foregoing, collectively, the "Indemnified Liabilities"); provided that the
                              -----------------------    --------         
Company shall have no obligation hereunder to any Indemnified Person with
respect to Indemnified Liabilities to the extent they are found by a final
decision of a court of competent jurisdiction to have resulted solely from the
gross negligence or willful misconduct of such Indemnified Person.  The
agreements in this Section and in Section 11.4 shall survive the termination of
the Commitments, the termination or expiration of all Letters of Credit and the
payment of all other Obligations.

          11.6  Payments Set Aside.  To the extent that any Loan Party makes a
                ------------------

right of set-off, and such payment or the proceeds of such set-off or any part
thereof are subsequently invalidated, declared to be fraudulent or preferential,
set aside or required (including pursuant to any settlement entered into by the
Agent or such Bank in its discretion) to be repaid to a trustee, receiver or any
other party, in connection with any Insolvency Proceeding or otherwise, then (a)
to the extent of such recovery the obligation or part thereof originally
intended to be satisfied shall be revived and continued in full force and effect
as if such payment had not been made or such set-off had not occurred, and (b)
each Bank severally agrees to pay to the Agent upon demand its pro rata share of
any amount so recovered from or repaid by the Agent.

          11.7  Successors and Assigns.  The provisions of this Agreement shall
                ----------------------                                         
be binding upon and inure to the benefit of the parties hereto and their
respective successors and assigns, except that no Loan Party may assign or
transfer any of its rights or obligations under this Agreement without the prior
written consent of the Agent and each Bank.

          11.8  Assignments, Participations, Etc.  (a) Any Bank may, with the

written consent of the Borrowers' Designee, the Agent, the Swingline Bank and
the Issuing Bank (which in each case shall not be unreasonably withheld), at any
time assign and delegate to one or more Eligible Assignees (each an "Assignee")
                                                                     --------

<PAGE>
 
L/C Obligations and the other rights and obligations of such Bank hereunder;
provided, however, that (i) no written consent of the Borrowers' Designee or the
Agent or the Issuing Bank or the Swingline Bank shall be required in connection
with any assignment and delegation by a Bank to an Eligible Assignee that is
another Bank or an Affiliate of such Bank; and (ii) except in connection with an
assignment of all of a Bank's rights and obligations with respect to its
Commitment, Loans and L/C Obligations, any such assignment to an Eligible
Assignee that is not a Bank hereunder shall be equal to or greater than
$10,000,000; and provided further, however, that the Borrowers' Designee and the
Agent may continue to deal solely and directly with such Bank in connection with
the interest so assigned to an Assignee until (A) such Bank and its Assignee
shall have delivered to the Borrowers' Designee and the Agent an Assignment and
Acceptance Agreement substantially in the form of Exhibit G (an "Assignment and
Acceptance"), together with any Note or Notes subject to such assignment; (B) a
written notice of such assignment, together with payment instructions, addresses
and related information with respect to the Assignee, in substantially the form
of the Notice of Assignment and Acceptance attached as Schedule 1 to the
Assignment and Acceptance, shall have been given to the Borrowers' Designee and
the Agent by such Bank and the Assignee; (C) the assignor Bank or Assignee shall
have paid to the Agent a processing fee in the amount of $3,500; and (D) the
Issuing Bank, the Swingline Bank and the Borrowers' Designee each consents to
such assignment in accordance with this Section. In connection with any
assignment by BofA, its Swingline Commitment may be assigned in whole (and not
part) and only in connection with an assignment transaction involving an
assignment of all of its Commitment and Loans, and the Assignment and Acceptance
may be appropriately modified to include an assignment and delegation of its
Swingline Commitment and any outstanding Swingline Loans.

          (b) From and after the date that the Agent notifies the assignor Bank
that the Agent has received (and, if required, provided its consent with respect
to and, if necessary, received the consent of the Borrowers' Designee with
respect to) an executed Assignment and Acceptance and payment of the above-
referenced processing fee, (i) the Assignee thereunder shall be a party hereto
and, to the extent that rights and obligations hereunder have been assigned to
it pursuant to such Assignment and Acceptance, shall have the rights and
obligations of a Bank under the Loan Documents, (ii) this Agreement shall be
deemed to be amended to the extent, but only to the extent, necessary to reflect
the addition of the Assignee and the resulting adjustment of the Commitments
arising therefrom, and (iii) the assignor Bank shall, to the extent that rights
and obligations hereunder and under the other Loan Documents have been assigned
by it pursuant to such Assignment and Acceptance, relinquish its rights and be
released from its obligations under the Loan Documents; provided, however, that
                                                        --------  -------      
the assignor Bank shall not relinquish its rights under Article IV or under
Sections 11.4 and 11.5 to the extent such rights relate to the time prior to the
effective date of the Assignment and Acceptance.  The Commitment allocated to
each Assignee shall reduce the Commitment of the assigning Bank pro tanto.
                                                                --- ----- 

          (c) Within five Business Days after its receipt of notice by the Agent
that it has received (and, if necessary, consented to) an executed Assignment
and Acceptance and payment of the processing fee (and provided that the Issuing
Bank, the Swingline Bank and the Borrowers' Designee each consents to such
assignment in accordance with subsection 11.8(a)), the Borrowers' Designee shall
execute and deliver to the Agent any new Notes requested by such Assignee
evidencing such Assignee's assigned Loans and Commitment and, if the assignor
Bank

                                      78
<PAGE>
 
has retained a portion of its Loans and its Commitment, replacement Notes as
requested by the assignor Bank evidencing the Loans and Commitment retained by
the assignor Bank (such Notes to be in exchange for, but not in payment of, the
Notes held by such Bank, if any).

          (d) Any Bank may at any time sell to one or more commercial banks or
other Persons not Affiliates of any Borrower (a "Participant") participating
                                                 -----------                
interests in any Loans, the Commitment of that Bank and the other interests of
that Bank (the "originating Bank") hereunder and under the other Loan Documents;
                                                                                
provided, however, that (i) the originating Bank's obligations under this
- --------  -------                                                        
Agreement shall remain unchanged, (ii) the originating Bank shall remain solely
responsible for the performance of such obligations, (iii) the Borrowers, the
Borrowers' Designee, the Issuing Bank and the Agent shall continue to deal
solely and directly with the originating Bank in connection with the originating
Bank's rights and obligations under this Agreement and the other Loan Documents,
and (iv) no Bank shall transfer or grant any participating interest under which
the Participant has rights to approve any amendment to, or any consent or waiver
with respect to, this Agreement or any other Loan Document, except to the extent
such amendment, consent or waiver would require unanimous consent of the Banks
as described in the first proviso to Section 11.1.  In the case of any such
                    ----- -------                                          
participation, the Participant shall be entitled to the benefit of Sections 4.1,
4.3 and 11.5 as though it were also a Bank hereunder, and if amounts outstanding
under this Agreement are due and unpaid, or shall have been declared or shall
have become due and payable upon the occurrence of an Event of Default, each
Participant shall be deemed to have the right of set-off in respect of its
participating interest in amounts owing under this Agreement to the same extent
as if the amount of its participating interest were owing directly to it as a
Bank under this Agreement, provided that such Participant shall not be entitled
                           --------                                            
to the benefits of Section 4.1 as a result of such Participant's failure to
comply with the requirements of Section 10.10(a).

          (e) Notwithstanding any other provision in this Agreement, any Bank
may at any time create a security interest in, or pledge, all or any portion of
its rights under and interest in this Agreement and any Note held by it (other
than in respect of Swingline Loans) in favor of any Federal Reserve Bank in
accordance with Regulation A of the FRB or U.S. Treasury Regulation 31 CFR
'203.14, and such Federal Reserve Bank may enforce such pledge or security
interest in any manner permitted under applicable law.

Affiliates to take normal and reasonable precautions and exercise due care to

Affiliates shall use any such information other than in connection with or in
enforcement of this Agreement and the other Loan Documents or in connection with
other business now or hereafter existing or contemplated with the Company or any
Subsidiary; except to the extent such information (i) was or becomes generally
available to the public other than as a result of disclosure by such Bank, or
(ii) was or becomes available on a non-confidential basis from a source other
than the Company or any Subsidiary, provided that such source is not bound by a

accordance with the provisions of any applicable Requirement of Law; (D) to the
extent reasonably required in connection with any litigation or proceeding to

Agent, any Bank or their respective Affiliates may be party; (E) to the extent
reasonably required in connection with the exercise of any remedy hereunder or
under any other Loan Document; (F) to such Bank's independent auditors, legal

provided by law, if an Event of Default exists or the Loans have been
accelerated, each Bank is authorized at any time and from time to time, without
prior notice to the Loan Parties or the Borrowers' Designee, any such notice
being waived by the Borrowers to the fullest extent permitted by law, to set off
and apply any and all deposits (general or special, time or demand, provisional
or final) at any time held by, and other indebtedness at any time owing by, such
Bank to or for the credit or the account of any Loan Party against any and all
Obligations owing to such Bank, now or hereafter existing, irrespective of
whether or not the Agent or such Bank shall have made demand under this
Agreement or any Loan Document and although such Obligations may be contingent
or unmatured.  Each Bank agrees promptly to notify the Borrowers' Designee and
the Agent after any such set-off and application made by such Bank; provided,
                                                                    -------- 
however, that the failure to give such notice shall not affect the validity of

Currency") other than that in which such sum is denominated in accordance with
- --------                                                                      
the applicable provisions of this Agreement (the "Agreement Currency"), be
                                                  ------------------      
discharged only to the extent that on the Business Day following receipt by the
Agent of any sum adjudged to be so due in the Judgment Currency, the Agent may
in accordance with normal banking procedures purchase the Agreement Currency
with the Judgment Currency.  If the amount of the Agreement Currency so
purchased is less than the sum originally due to the Agent in the Agreement
Currency, each Loan Party agrees, as a separate obligation and notwithstanding
any such judgment, to indemnify the Agent or the Person to 

                                      81
<PAGE>
 
whom such obligation was owing against such loss. If the amount of the Agreement
currency so purchased is greater than the sum originally due to the Agent in
such currency, the Agent agrees to return the amount of any excess to the
applicable Loan Party (or to any other Person who may be entitled thereto under
applicable law).

           11.18  Guaranty.
                  -------- 

          (a) Guaranty.  Each of the Guarantors, unconditionally and
              --------                                              
irrevocably, jointly and severally guarantees to the Agent, the Swingline Bank,
the Issuing Bank, the Arranger and the Banks, and their respective successors,
endorsers, transferees and assigns (the "Guaranteed Persons"), the full and
                                         ------------------                
prompt payment when due (whether at stated maturity, by required prepayment,
declaration, acceleration, demand or otherwise) and performance of the
Obligations of the Borrowers to any Guaranteed Person (the "Guaranteed
                                                            ----------
Obligations").  The Guaranteed Obligations include interest which, but for an
- -----------                                                                  
Insolvency Proceeding, would have accrued on such Guaranteed Obligations,
whether or not a claim is allowed against the Borrowers for such interest in any
such Insolvency Proceeding.

          (b) Separate Obligation.  Each Guarantor acknowledges and agrees (i)
              -------------------                                             
that the Guaranteed Obligations are separate and distinct from any indebtedness,
obligations or liabilities arising under or in connection with any other
agreement, instrument or guaranty, including under any provision of this
Agreement other than this Section 11.18, executed at any time by such Guarantor
in favor of any Guaranteed Person, and (ii) such Guarantor shall pay and perform
all of the Guaranteed Obligations as required under this Section 11.18, and each
Guaranteed Person may enforce any and all of its rights and remedies hereunder,
without regard to any other agreement, instrument or guaranty, including any
provision of this Agreement other than this Section 11.18, at any time executed
by such Guarantor in favor of any Guaranteed Person, regardless of whether or
not any such other agreement, instrument or guaranty, or any provision thereof
or hereof, shall for any reason become unenforceable or any of the indebtedness,
obligations or liabilities thereunder shall have been discharged, whether by
performance, avoidance or otherwise.  Each Guarantor acknowledges that in
providing benefits to the Borrowers and such Guarantor, the Guaranteed Persons
are relying upon the enforceability of this Section 11.18 and the Guaranteed
Obligations as separate and distinct indebtedness, obligations and liabilities
of such Guarantor, and each Guarantor agrees that each Guaranteed Person would
be denied the full benefit of their bargain if at any time this Section 11.18 or
the Guaranteed Obligations were treated any differently.  The fact that the
Guaranty of each Guarantor is set forth in this Agreement rather than in a
separate guaranty document is for the convenience of the Borrowers and the
Guarantors and shall in no way impair or adversely affect the rights or benefits
of any Guaranteed Person under this Section 11.18.  Each Guarantor agrees to
execute and deliver a separate agreement, immediately upon request at any time
of any Guaranteed Person, evidencing such Guarantor's obligations under this
Section 11.18.  Upon the occurrence of any Event of Default, a separate action
or actions may be brought against each Guarantor, whether or not the Borrowers
or any other Guarantor or Person is joined therein or a separate action or
actions are brought against the Borrowers or any other Guarantor or Person.

          (c) Limitation of Guaranty.  To the extent that any court of competent
              ----------------------                                            
jurisdiction shall impose by final judgment under applicable law (including the
California Uniform Fraudulent Transfer Act and (S)544 and 548 of the Bankruptcy
Code) any limitations on the amount of any Guarantor's liability with respect to
the Guaranteed Obligations which any

                                      82
<PAGE>
 
Guaranteed Person can enforce under this Section 11.18, each Guaranteed Person
by its acceptance hereof accepts such limitation on the amount of such
Guarantor's liability hereunder to the extent needed to make this Section 11.18
fully enforceable and nonavoidable.

          (d) Liability of Guarantor.  The liability of each Guarantor under
              ----------------------                                        
this Section 11.18 shall be irrevocable, absolute, independent and
unconditional, and shall not be affected by any circumstance which might
constitute a discharge of a surety or guarantor other than the indefeasible
payment and performance in full of all Guaranteed Obligations.  In furtherance
of the foregoing and without limiting the generality thereof, each Guarantor
agrees as follows:

           (i) such Guarantor's liability hereunder shall be the immediate,
     direct, and primary obligation of such Guarantor and shall not be
     contingent upon any Guaranteed Person's exercise or enforcement of any
     remedy it may have against the Borrowers or any other Person, or against
     any collateral or other security for any Guaranteed Obligations;

           (ii) this Guaranty is a guaranty of payment when due and not merely
     of collectibility;

           (iii)  such Guarantor's payment of a portion, but not all, of the
     Guaranteed Obligations shall in no way limit, affect, modify or abridge
     such Guarantor's liability for any portion of the Guaranteed Obligations
     remaining unsatisfied; and

           (iv) such Guarantor's liability with respect to the Guaranteed
     Obligations shall remain in full force and effect without regard to, and
     shall not be impaired or affected by, nor shall such Guarantor be
     exonerated or discharged by, any of the following events:

            (1)  any Insolvency Proceeding;

            (2) any limitation, discharge, or cessation of the liability of any
          Borrower or any other guarantor or Person for any Guaranteed
          Obligations due to any statute, regulation or rule of law, or any
          invalidity or unenforceability in whole or in part of any of the
          Guaranteed Obligations or the Loan Documents;

            (3) any merger, acquisition, consolidation or change in structure of
          any Borrower or any other Guarantor or Person, or any sale, lease,
          transfer or other disposition of any or all of the assets or shares of
          any Borrower or any other Guarantor or other Person;

            (4) any assignment or other transfer, in whole or in part, of any
          Guaranteed Person's interests in and rights under this Guaranty or the
          other Loan Documents;

            (5) any claim, defense, counterclaim or set-off, other than that of
          prior performance, that any Borrower, such Guarantor, any other
          guarantor or other Person may have or assert, including any defense of
          incapacity or lack of corporate or other authority to execute any of
          the Loan Documents;

                                      83
<PAGE>
 
            (6) any Guaranteed Person's amendment, modification, renewal,
          extension, cancellation or surrender of any Loan Document or any
          Guaranteed Obligations;

            (7) any Guaranteed Person's exercise or nonexercise of any power,
          right or remedy with respect to any Guaranteed Obligations or any
          collateral;

            (8) any Guaranteed Person's vote, claim, distribution, election,
          acceptance, action or inaction in any Insolvency Proceeding;

            (9) any other guaranty, whether by any Guarantor or any other
          Person, of all or any part of the Guaranteed Obligations or any other
          indebtedness, obligations or liabilities of any Guaranteed Person.

          (e) Consents of Guarantor.  Each Guarantor hereby unconditionally
              ---------------------                                        
consents and agrees that, without notice to or further assent from such
Guarantor:

           (i) the principal amount of the Guaranteed Obligations may be
     increased or decreased and additional indebtedness or obligations of the
     Borrowers under the Loan Documents may be incurred and the time, manner,
     place or terms of any payment under any Loan Document be extended or
     changed, by one or more amendments, modifications, renewals or extensions
     of any Loan Document or otherwise;

           (ii) the time for any Borrower's (or any other Person's) performance
     of or compliance with any term, covenant or agreement on its part to be
     performed or observed under any Loan Document may be extended, or such
     performance or compliance waived, or failure in or departure from such
     performance or compliance consented to, all in such manner and upon such
     terms as any Guaranteed Person (or the Majority Banks, as the case may be)
     may deem proper;

           (iii)  each Guaranteed Person may request and accept other guarantees
     and may take and hold other security as collateral for the Guaranteed
     Obligations, and may, from time to time, in whole or in part, exchange,
     sell, surrender, release, subordinate, modify, waive, rescind, compromise
     or extend such other guaranties or security and may permit or consent to
     any such action or the result of any such action, and may apply such
     security and direct the order or manner of sale thereof;

           (iv) each Guaranteed Person may exercise, or waive or otherwise
     refrain from exercising, any other right, remedy, power or privilege even
     if the exercise thereof affects or eliminates any right of subrogation or
     any other right of such Guarantor against the Borrower;

           (f) Guarantor's Waivers.  Each Guarantor waives and agrees not to
               -------------------                                          
assert:

           (i) any right to require any Guaranteed Person to proceed against any
     Borrower, any other guarantor or any other Person, or to pursue any other
     right, remedy, power or privilege of such Guaranteed Person whatsoever;

                                      84 
<PAGE>
 
           (ii) the defense of the statute of limitations in any action
     hereunder or for the collection or performance of the Guaranteed
     Obligations;

           (iii)  any defense arising by reason of any lack of corporate or
     other authority or any other defense of any Borrower, such Guarantor or any
     other Person;

           (iv) any defense based upon any Guaranteed Person's errors or
     omissions in the administration of the Guaranteed Obligations;

           (v) any rights to set-offs and counterclaims;

           (vi) without limiting the generality of the foregoing, to the fullest
     extent permitted by law, any defenses or benefits that may be derived from
     or afforded by applicable law limiting the liability of or exonerating
     guarantors or sureties, or which may conflict with the terms of this
     Section 11.18, including any and all benefits that otherwise might be
     available to such Guarantor under California Civil Code (S)(S)1432, 2809,
     2810, 2815, 2819, 2839, 2845, 2848, 2849, 2850, 2899 and 3433 and
     California Code of Civil Procedure (S)(S)580a, 580b, 580d and 726; and

           (vii)  any and all notice of the acceptance of this Guaranty, and any
     and all notice of the creation, renewal, modification, extension or accrual
     of the Guaranteed Obligations, or the reliance by any Guaranteed Person
     upon this Guaranty, or the exercise of any right, power or privilege
     hereunder.  The Guaranteed Obligations shall conclusively be deemed to have
     been created, contracted, incurred and permitted to exist in reliance upon
     this Guaranty.  Each Guarantor waives promptness, diligence, presentment,
     protest, demand for payment, notice of default, dishonor or nonpayment and
     all other notices to or upon any Borrower, such Guarantor or any other
     Person with respect to the Guaranteed Obligations.

          (g) Financial Condition of Borrowers.  No Guarantor shall have any
              --------------------------------                              
right to require any Guaranteed Person to obtain or disclose any information
with respect to:  the financial condition or character of the Borrowers or the
ability of the Borrowers to pay and perform the Guaranteed Obligations; the
Guaranteed Obligations; any collateral or other security for any or all of the
Guaranteed Obligations; the existence or nonexistence of any other guarantees of
all or any part of the Guaranteed Obligations; any action or inaction on the
part of any Guaranteed Person or any other Person; or any other matter, fact or
occurrence whatsoever.  Each Guarantor hereby acknowledges that it has
undertaken its own independent investigation of the financial condition of the
Borrowers and all other matters pertaining to this Guaranty and further
acknowledges that it is not relying in any manner upon any representation or
statement of any Guaranteed Person with respect thereto.

          (h) Subrogation.  Until the Guaranteed Obligations shall be satisfied
              -----------                                                      
in full and the Revolving Commitments shall be terminated, each Guarantor shall
not have, and shall not directly or indirectly exercise (i) any rights that it
may acquire by way of subrogation under this Section 11.18, by any payment
hereunder or otherwise, (ii) any rights of contribution, indemnification,
reimbursement or similar suretyship claims arising out of this Section 11.18 or
(iii) any other right which it might otherwise have or acquire (in any way
whatsoever) which could entitle it at any time to share or participate in any
right, remedy or security of any 

                                      85
<PAGE>
 
Guaranteed Person as against the Borrowers or other guarantors, whether in
connection with this Section 11.18, any of the other Loan Documents or
otherwise. If any amount shall be paid to any Guarantor on account of the
foregoing rights at any time when all the Guaranteed Obligations shall not have
been paid in full, such amount shall be held in trust for the benefit of each
Guaranteed Person and shall forthwith be paid to the Agent to be credited and
applied to the Guaranteed Obligations, whether matured or unmatured, in
accordance with the terms of the Loan Documents.

          (i) Continuing Guaranty.  This Guaranty is a continuing guaranty and
              -------------------                                             
agreement of subordination and shall continue in effect and be binding upon each
Guarantor until termination of the Commitments and payment and performance in
full of all Guaranteed Obligations, including Guaranteed Obligations which may
exist continuously or which may arise from time to time under successive
transactions, and each Guarantor expressly acknowledges that this Guaranty shall
remain in full force and effect notwithstanding that there may be periods in
which no Guaranteed Obligations exist.

          (j) Reinstatement.  This Guaranty shall continue to be effective or
              -------------                                                  
shall be reinstated and revived, as the case may be, if, for any reason, any
payment of the Guaranteed Obligations by or on behalf of any Borrower (or
receipt of any proceeds of collateral) shall be rescinded, invalidated, declared
to be fraudulent or preferential, set aside, voided or otherwise required to be
repaid to any Borrower, its estate, trustee, receiver or any other Person
(including under the Bankruptcy Code or other state or federal law), or must
otherwise be restored by any Guaranteed Person, whether as a result of
Insolvency Proceedings or otherwise.  All losses, damages, costs and expenses
that any Guaranteed Person may suffer or incur as a result of any voided or
otherwise set aside payments shall be specifically covered by the indemnity in
favor of the Banks, the Issuing Bank and the Agent contained in Section 11.5.

          (k) Substantial Benefits.  The funds that have been borrowed from the
              --------------------                                             
Banks by the Borrowers, and the Issuance of any Letter of Credit by the Issuing
Bank, have been and are to be contemporaneously used for the direct or indirect
benefit of the Borrowers and each Guarantor.  It is the position, intent and
expectation of the parties that the Borrowers and each Guarantor have derived
and will derive significant and substantial direct or indirect benefits from the
accommodations that have been made by the Banks, the Swingline Bank and the
Issuing Bank under the Loan Documents.

          (l) Knowing and Explicit Waivers.  EACH GUARANTOR ACKNOWLEDGES THAT IT
              ----------------------------                                      
EITHER HAS OBTAINED THE ADVICE OF LEGAL COUNSEL OR HAS HAD THE OPPORTUNITY TO
OBTAIN SUCH ADVICE IN CONNECTION WITH THE TERMS AND PROVISIONS OF THIS SECTION
11.18.  EACH GUARANTOR ACKNOWLEDGES AND AGREES THAT EACH OF THE WAIVERS AND
CONSENTS SET FORTH HEREIN ARE MADE WITH FULL KNOWLEDGE OF THEIR SIGNIFICANCE AND
CONSEQUENCES, AND THAT ALL SUCH WAIVERS AND CONSENTS HEREIN ARE EXPLICIT AND
KNOWING AND WHICH EACH GUARANTOR EXPECTS TO BE FULLY ENFORCEABLE.

          11.19  Release of Subsidiary Guarantors and Additional Borrowers.  The
                 ---------------------------------------------------------      
Company may at any time deliver to the Agent a certificate from a Responsible
Officer, certifying as of the date of the certificate that, after the
consummation of the transaction or series of transactions described in such
certificate (which certification shall also state that such transactions,

                                      86
<PAGE>
 
individually or in the aggregate, will be in compliance with the terms and
conditions of this Agreement, including to the extent applicable Sections 8.2
and 8.3, and that no Event of Default existed, exists or will exist, as the case
may be, immediately before, as a result of or immediately after giving effect to
such transaction or transactions and termination), the Subsidiary Guarantor or
Additional Borrower, as the case may be, identified in such certification will
no longer be a Subsidiary of the Company.  Effective upon the consummation of
the transaction or series of transactions described in such certificate and, in
the case of any Additional Borrower, the payment in full of all principal of,
interest on, reimbursement obligations in respect of and fees related to any
outstanding Credit Extensions in favor of such Additional Borrower and the
termination (or arrangement to the satisfaction of the Issuing Bank for the
termination) of any Letter of Credit issued for the account of such Additional
Borrower, the Subsidiary identified in such certification shall thereupon
automatically cease to be a Subsidiary Guarantor or Additional Borrower, as the
case may be, hereunder and shall cease to be a party hereto and, in the case of
a Subsidiary Guarantor, shall thereupon automatically be released from its
obligations under Section 11.18.  The Company shall promptly notify the Agent of
the consummation of any such transaction or series of transactions, as provided
in Section 7.13.  The Agent and each Bank shall, at the Company's expense,
execute and deliver such instruments as the Company may reasonably request to
evidence such release.

          11.20  Entire Agreement.  This Agreement, together with the other Loan
                 ----------------                                               
Documents, embodies the entire agreement and understanding among the Company,
the Banks, the Swingline Bank and the Agent, and supersedes all prior or
contemporaneous agreements and understandings of such Persons, oral or written,
relating to the subject matter hereof and thereof.

          The Leverage Ratio used to compute the Applicable Fee Amount and the
Applicable Margin shall be the Leverage Ratio set forth in the Compliance
Certificate most recently delivered by the Company to the Agent pursuant to
Section 7.2(a) of the Credit Agreement; changes in the Applicable Fee Amount and
the Applicable Margin resulting from a change in the Leverage Ratio shall become
effective upon delivery by the Company to the Agent of a new Compliance
Certificate pursuant to Section 7.2(a).  If the Company shall fail to deliver a
Compliance Certificate within the number of days after the end of any fiscal
quarter or fiscal year as required pursuant to Section 7.2(a) (without giving
effect to any grace period), the Applicable Fee Amount and the Applicable Margin
from the first day after the date on which such Compliance Certificate was
required to be delivered to the Agent to the day the Company delivers to the
Agent a Compliance Certificate shall conclusively equal the highest Applicable
Fee Amount and Applicable Margin set forth above.  Notwithstanding the
foregoing, the Applicable Fee Amount and the Applicable Margin shall be no lower
than Level 3 for the period commencing on the Closing Date and ending on
December 31, 1998.

          If on any date (including any date during the 6-month period following
the Closing Date) the Effective Amount of all Revolving Loans plus the Effective
                                                              ----

       (iii)   if one or more of the conditions set forth in the preceding
               clause (ii) are satisfied, then the historical financial results
               of such Acquired Subsidiary shall be included in the consolidated
               financial results of JM as follows: (A) JM shall determine in
               accordance with GAAP the relevant financial results of such
               Acquired Subsidiary for the period of four fiscal quarters of
               such Acquired Subsidiary ending on the last day of its fiscal

               dividing (x) the number of days elapsed from the first day of the
               Compliance Period to the date of the Acquisition of such Acquired
               Subsidiary, by (y) 365; provided, however, that any increase in

               Compliance Period.

     (b)  For purposes of determining any Applicable Fee Amount or any
          Applicable Margin or calculating JM's compliance with Sections 8.10,

2.1    Amounts and Terms of Commitments.
       -------------------------------- 

     (a)  The Revolving Loans.  Each Bank severally agrees, on the terms and
          -------------------                                               
          conditions set forth herein, to make loans available to the Borrower
          by way of any one or more of the following:

          (i)    Canadian Dollar Advances
          (ii)   U.S. Dollar Loans
          (iii)  LIBOR Loans
          (iv)   BA Advances

          (each such loan, a "Revolving Loan") from time to time on any Business
                              --------------                                    
          Day during the period from the Loan Availability Date to the Revolving
          Termination Date, in an aggregate principal amount not to exceed at
          any time the Canadian 

                                      25

          Dollar amount set forth opposite such Bank's name on Schedule 2.1
          under the heading "Commitment" (such amount, as the same may be
          reduced under Section 2.9 or reduced or increased as a result of one
          or more assignments under Section 11.8, such Bank's "Commitment");
          provided, however, that, after giving effect to any Borrowing of
          Revolving Loans, the Canadian Dollar Equivalent Amount of all
          outstanding Revolving Loans shall not at any time exceed the Aggregate
          Commitment. Within the limits of each Bank's Commitment, and subject
          to the other terms and conditions hereof, the Borrower may borrow
          Revolving Loans under this Section 2.1(a), prepay such Loans under
          Section 2.10 and reborrow under this Section 2.1(a).

     (b)  Borrower's Request for Increased Commitment. The Borrower may request
          -------------------------------------------                          
          an increase in the Aggregate Commitment upon written notice to the
          Agent, such notice to be given to the Agent on or before the first
          anniversary date of the Closing Date.  Neither the Agent nor any of
          the Banks shall be under any obligation to provide all or any portion
          of such requested increase in the Aggregate Commitment but upon
          receipt of any such notice from the Borrower the Agent shall use
          commercially reasonable efforts to seek additional commitments from
          the existing Banks or to seek commitments from other financial
          institutions in amounts sufficient to total the requested increased
          Commitment.  The Agent shall notify the Borrower whether or not it has
          been able to do so.

2.2    Loan Accounts.
       ------------- 

     (a)  The Loans (other than BA Advances) made by each Bank shall be
          evidenced by one or more accounts or records maintained by such Bank,
          as the case may be, in the ordinary course of business. The accounts
          or records maintained by the Agent, and each Bank shall be conclusive
          evidence, absent manifest error, of the amount of the Loans made by
          the Banks to the Borrower, and the interest and payments thereon.  Any
          failure so to record or any error in doing so shall not, however,
          limit or otherwise affect the obligation of the Borrower hereunder to
          pay any amount owing with respect to the Loans.

     (b)  Upon the request of any Bank made through the Agent, the Loans (other
          than BA Advances) made by such Bank shall be evidenced by one or more
          Notes, which the Borrower shall execute and deliver, as applicable,
          instead of or in addition to loan accounts. Each such Bank shall
          endorse on the schedules annexed to its Note(s) the date, amount and
          maturity of each Loan (other than a BA Advance) made by it and the
          amount and Applicable Currency of each payment of principal made by
          the Borrower with respect thereto. Each such Bank is irrevocably
          authorized by the Borrower to endorse its Note(s) and each Bank's
          record shall be conclusive evidence absent manifest error; provided,
                                                                     ---------
          however, that the failure of a Bank to make, or an error in making, a
          -------                                                              
          notation thereon with respect to any Loan shall not limit or otherwise
          affect the obligations of the Borrower hereunder or under any such
          Note to such Bank.

2.3    Procedure for Borrowing.
       ----------------------- 

     (a)  Each Borrowing of Revolving Loans shall be made upon the Borrower's
          Designee's irrevocable written notice delivered to the Agent in the
          form of a Notice of Borrowing (which notice must be received by the
          Agent (i) prior to 11:00 am. (Toronto time) three Business Days prior
          to the requested Borrowing Date, in the case of LIBOR Loans; (ii)
          prior to 12:00 p.m. (Toronto time) two Business Days prior to the
          requested Borrowing Date, in the case of BA Advances;  and (iii) prior
          to 11:00 a.m. (Toronto time) on the requested Borrowing Date in the
          case of any other Loan, specifying:

          (A)  except in the case of BA Advances, the amount of the Borrowing,
               which shall be in a Minimum Amount;

          (B)  the requested Borrowing Date, which shall be a Business Day;

          (C)  the Type of Loans comprising the Borrowing;

          (D)  in the case of LIBOR Loans, the duration of the initial Interest
               Period applicable to such LIBOR Loans included in such notice,
               subject to the provisions of the definition of "Interest Period"
               herein. If the Notice of Borrowing fails to specify the duration
               of the Interest Period for any Borrowing comprised of LIBOR
               Loans, such Interest Period shall be one month; and

          (E)  in the case of BA Advances, the aggregate face amount (which
               shall be in a Minimum Amount) and term (subject to the provisions
               of Article III) of any drafts or bills of exchange to be issued
               by the Borrower in conjunction with a BA Advance.

          Upon receipt of any Notice of Borrowing of Revolving Loans, the Agent
          will promptly notify each Bank thereof and of the amount of such
          Bank's Pro Rata Share of the Borrowing (expressed in the Applicable
          Currency of the Borrowing).

     (b)  Each Bank shall accept its Pro Rata Share of Bankers' Acceptances and
          purchase its own Bankers' Acceptances as provided for in Article III
          below.

     (c)  Each Bank will make the amount of its Pro Rata Share of each Borrowing
          of Revolving Loans (other than BA Advances, as to which Section 3.2
          shall apply) available to the Agent for the account of the Borrower at
          the Agent's Payment Office on the Borrowing Date requested by the
          Borrower's Designee in Same Day Funds and in the requested currency by
          2:00 p.m. (Toronto time). The proceeds of all such Borrowings will
          then be made available to the Borrower by the Agent at such office by
          crediting the account of the Borrower with the aggregate of the
          amounts made available to the Agent by the Banks and in like funds as
          received 

                                      22

          by the Agent, or if requested by Borrower's Designee, by wire transfer
          in accordance with written instructions provided to the Agent by the
          Borrower's Designee of such funds as received by the Agent, less
          customary fees for such wire transfer, unless on the date of the
          Borrowing all or any portion of the proceeds thereof shall than be
          required to be applied to the repayment of any outstanding Loans, in
          which case such proceeds or portion thereof shall be applied to the
          payment of such Loans.

2.4     Conversion and Continuation Elections.
        ------------------------------------- 

     (a)  The Borrower's Designee may, upon irrevocable written notice in
          accordance with subsection 2.4(b) elect, as of any Business Day, in
          the case of Canadian Dollar Advances or U.S. Dollar Loans or on the
          maturity date of Loans in the form of outstanding maturing Bankers'
          Acceptances or as of the last day of the applicable Interest Period,
          in the case of any LIBOR Loans, to continue or convert any such Loans
          (or any part thereof in an amount not less than a Minimum Amount) into
          Loans of any other Type; provided, that if at any time the aggregate
                                   ---------                                  
          amount of LIBOR Loans in respect of any Borrowing is reduced, by
          payment, prepayment, or conversion of part thereof to be less than
          $1,000,000 (U.S.), such LIBOR Loans shall automatically convert into
          U.S. Dollar  Loans, and on and after such date the right of the
          Borrower to continue such Loans as, and convert such Loans into, LIBOR
          Loans shall terminate.

     (b)  Each such conversion and continuation of Revolving Loans shall be made
          upon delivery by the Borrower's Designee of a Notice of
          Conversion/Continuation to the Agent. Each such Notice of
          Conversion/Continuation must be received by the Agent (i) not later
          than 11:00 a.m. (Toronto time) three Business Days in advance of the
          Conversion/Continuation Date, if any Loans are to be converted into or
          continued as LIBOR Loans; (ii) not later than 12:00 p.m. (Toronto
          time) two Business Days in advance of the Conversion/Continuation
          Date, if any Loans are to be converted into or continued as BA
          Advances (such continuation of a BA Advance also being referred to
          herein as a "rollover");  and (iii) not later than 12:00 p.m. (Toronto
          time) on the Conversion/Continuation Date, if the Loans are to be
          converted into Canadian Dollar Advances or U.S. Dollar Loans,
          specifying:

          (A)  the proposed Conversion/Continuation Date;

          (B)  the aggregate amount of Loans to be converted or continued;

          (C)  the Type of Loans resulting from the proposed conversion or
               continuation; and

          (D)  other than in the case of conversions into BA Advances (as to
               which the provisions of subsection 2.4(d) shall also apply),
               Canadian Dollar Advances or U.S. Dollar Loans, the duration of
               the requested Interest Period.

                                      23
<PAGE>
 
     (c)  If upon the expiration of any Interest Period applicable to LIBOR
          Loans, the Borrower's Designee has failed to select timely a new
          Interest Period to be applicable to such LIBOR Loans, or if any Event
          of Default then exists, the Borrower's Designee shall be deemed to
          have elected to convert such LIBOR Loans into U.S. Dollar Loans
          effective as of the expiration date of such Interest Period.

     (d)  A conversion from a BA Advance to another Type of Loan or a rollover
          of a BA Advance may occur only on the maturity date of the relevant
          Bankers' Acceptance and subject to the other terms of this Agreement.
          In connection with the maturity of Bankers' Acceptances, the Borrower
          shall do one or a combination of the following:

          (i)  effect a rollover of such BA Advance by the Borrower's Designee
               delivering a Notice of Conversion/Continuation to the Agent in
               accordance with subsection 2.4(b) in which case the Borrower
               shall, on the relevant maturity date of the Bankers' Acceptances
               comprising such BA Advance, pay the Agent on behalf of the Banks
               an amount equal to the amount by which the face amount of the
               maturing Bankers' Acceptances exceeds the BA Proceeds of any
               Bankers' Acceptances newly issued in connection with such
               rollover (in respect of which the Borrower's Designee must
               separately deliver a Notice of Borrowing and comply with Article
               III);

          (ii) effect a conversion of such BA Advance into another Type of Loan
               pursuant to the foregoing subsections by obtaining a Loan, the
               proceeds of which are sufficient to pay the face amount of such
               maturing Bankers' Acceptances; or

         (iii) pay to the Agent an amount equal to the face amount of the
               Bankers' Acceptances comprising such BA Advance on their
               maturity.

          If the Borrower's Designee fails to so notify the Agent, or the
          Borrower fails to so pay the Bankers' Acceptances, the BA Advance
          shall be converted to a Canadian Dollar Advance on the maturity date
          of such Bankers' Acceptances.

     (e)  The Borrower may effect a partial rollover of a BA Advance or a
          partial conversion into a BA Advance with the remainder of such
          maturing BA Advance being either converted or repaid in accordance
          with the provisions of this Agreement subject in all cases to the
          Borrower complying with the provisions of this Agreement.

     (f)  The Agent will promptly notify each Bank of its receipt of a Notice of
          Conversion/Continuation of Revolving Loans, or, if no timely notice is
          provided by the Borrower's Designee in respect of a LIBOR Loan or a BA
          Advance, the 

                                      24
<PAGE>
 
          Agent will promptly notify each Bank of the details of any automatic
          conversion. All conversions and continuations of Revolving Loans shall
          be made ratably according to the respective outstanding principal or
          face amounts of the Loans with respect to which the notice was given
          held by each Bank.

     (g)  Unless the Majority Banks otherwise consent, during the existence of
          an Event of Default, neither the Borrower nor the Borrower's Designee
          may elect to have any Borrowing hereunder nor to have any Loan
          continued, rolled over or converted into another Type of Loan
                                                                       
          (provided that during the existence of an Event of Default until the
          ---------                                                           
          Agent exercises any of its remedies referred to in Section 9.2, LIBOR
          Loans may be converted into U.S. Dollar Loans and BA Advances on
          maturity may be converted into Canadian Dollar Advances).

        ------------------------------                                    
Computation Date, the Agent shall have determined that the Canadian Dollar
Equivalent Amount of the aggregate principal amount of all Revolving Loans
outstanding exceeds the Aggregate Commitment by more than $375,000 (Cdn.), due
to a change in applicable rates of exchange between U.S. Dollars and Canadian
Dollars, then the Agent shall give notice to the Borrower's Designee that a
         ----                                                              
prepayment is required under this Section, and the Borrower agrees that it shall
make prepayments of Loans not later than the Business Day following the
Borrower's Designee's receipt of such notice such that, after giving effect to
such prepayment the aggregate Canadian Dollar Equivalent Amount of all Revolving
Loans does not exceed the Aggregate Commitment.

upon not less than three Business Days' prior notice from the Borrower's
Designee to the Agent, terminate the Commitments, or permanently reduce the
Commitments by an aggregate minimum amount of at least $1,000,000 (Cdn.) unless,
                                                                         ------ 
after giving effect thereto and to any prepayments of any Loans made on the
effective date thereof, (a) the Canadian Dollar Equivalent Amount of all
Revolving Loans would exceed the Aggregate Commitment then in effect.  Once
reduced in accordance with this Section 2.9, the Commitments may not be
increased. Any reduction of the Commitments shall be applied to each Bank
according to its Pro Rata Share.  All accrued facility fees to, but not
including, the effective date of any termination of the Commitments shall be
paid on the effective date of such termination. The Agent shall promptly forward
a copy of any such notice received under this subsection 2.9 to each of the
Banks.

2.10    Optional Prepayments. Subject to Section 4.4, the Borrower may, at any
        --------------------                                                  
time or from time to time, upon notice from the Borrower's Designee to the
Agent, ratably prepay Revolving Loans, other than BA Advances, in whole or in

prepayment date if the Loans to be prepaid are LIBOR Loans and (ii) no later
than 11:00 a.m. (Toronto time) on the prepayment date if the Loans to be repaid
are U.S. Dollar Loans or Canadian Dollar Advances. Such notice of prepayment
shall specify the date and amount of such prepayment and whether such prepayment
is of Canadian Dollar Advances, U.S. Dollar Loans, LIBOR Loans or any
combination thereof. Such notice shall not thereafter be revocable by the
Borrower's Designee or by the Borrower. The Agent will promptly notify each Bank
thereof and of such Bank's Pro Rata Share of such prepayment. If such notice is
given by the Borrower's Designee, the Borrower shall make such prepayment and
the payment amount specified in such notice shall be due and payable on the date
specified therein, together with (other than interest in the case of U.S. Dollar
Loans or Canadian Dollar Advances, which interest shall be payable in full on
the last day of the then current calendar quarter) accrued interest to each such

          together with all other outstanding or accrued amounts (whether for
          interest, fees, expenses or otherwise)

     (b)  At the option of the Borrower, upon written notice by the Borrower's
          Designee to the Agent to be given not more than 120 days but not less
          than thirty (30) days prior to the then applicable Revolving
          Termination Date, the Borrower's Designee may request that the
          Revolving Termination Date be extended by successive one-year periods;
          provided, however, that each such one-year extension shall require the
          unanimous approval of all of the Banks (such approval to be within the
          sole discretion of each Bank) and the written consent of each Loan
          Party; and provided further that if any Bank shall decline to approve
          of any such extension, the Borrower's Designee may (i) on or prior to
          the then applicable Revolving Termination Date, obtain a Replacement
          Bank to acquire and assume all or part of the Loans and Commitment of
          such non-consenting Bank in accordance with Section 4.8, or (ii)
          subject to repayment in full on or prior to the then applicable
          Revolving Termination Date of all Obligations then owing to each such
          non-consenting Bank, request that the Revolving Termination Date be
          extended only with respect to such Banks as have consented to such
          extension. The Borrower acknowledges and agrees that (A) no Bank shall
          have any obligation to increase its Commitment hereunder or otherwise
          acquire or assume all or any part of any other Bank's Loans or
          Commitment, whether in connection with an extension of the Revolving
          Termination Date pursuant to this subsection (b) or otherwise, and (B)
          in the event that some but not all of the Banks consent to an
          extension of the Revolving Termination Date pursuant this subsection
          (b) and the Borrower's Designee requests that the Revolving
          Termination Date be extended with respect 

                                      26
<PAGE>
 
          to such consenting Banks only, the Aggregate Commitment shall be
          automatically reduced to an amount equal to the combined Commitments
          of the remaining Banks.

2.13      Interest.
          -------- 

     (a)  Each Revolving Loan (other than BA Advances) shall bear interest on
          the outstanding principal amount thereof from the applicable Borrowing
          Date at a rate per annum equal to the Adjusted Prime Rate for Canadian
          Dollar Advances, the Base Rate for U.S. Dollar Loans, and the Offshore
          Rate for LIBOR Loans (and subject to the Borrower's right to convert
          to another Type of Loans under Section 2.4), plus in each case the
                                                       ----                 
          Applicable Margin.

     (b)  Interest on each Revolving Loan (other than BA Advances) shall be
          calculated on the daily outstanding balance thereof at the applicable
          interest rate (referred to in subsection 2.13(a) above) and paid by
          the Borrower (i) in the case of LIBOR Loans on each Interest Payment
          Date and (ii) in the case of Canadian Dollar Advances and U.S. Dollar
          Loans on the last day of the then current calendar quarter. Accrued
          interest shall also be paid on the date of any prepayment or repayment
          of LIBOR Loans under Section 2.7 or 2.10 attributable to the portion
          of the Loans so prepaid or repaid and upon payment (including
          prepayment) of LIBOR Loans in full thereof and, during the existence
          of any Event of Default, interest shall be paid by the Borrower on
          demand of the Agent.

     (c)  Notwithstanding subsection (a) of this Section, if any amount of
          principal of or interest on any Loan payable by the Borrower, or any
          other amount payable by the Borrower hereunder or under any other Loan
          Document is not paid in full when due (whether at stated maturity, by
          acceleration, demand or otherwise), the Borrower agrees to pay
          interest on such unpaid principal or other amount, from the date such
          amount becomes due until the date such amount is paid in full, and
          after as well as before any entry of judgment thereon to the extent
          permitted by law, payable on demand, at a rate per annum equal to the
          interest rate otherwise applicable thereto plus 2% per annum.
                                                     ----              

     (d)  Anything herein to the contrary notwithstanding, the obligations of
          the Borrower to any Bank hereunder shall be subject to the limitation
          that payments of interest shall not be required for any period for
          which interest is computed hereunder, to the extent (but only to the
          extent) that contracting for or receiving such payment by such Bank
          would be contrary to the provisions of any law applicable to such Bank
          limiting the highest rate of interest that may be lawfully contracted
          for, charged or received by such Bank, and in such event the Borrower
          shall pay such Bank interest at the highest rate permitted by
          applicable law.  Without limiting the generality of the foregoing, in
          no event shall the aggregate "interest", (as that term is defined in
          Section 347 of the Criminal Code (Canada), as the same may be amended,
          replaced or re-enacted from time to time,) payable in respect of the
          Loans and other Obligations hereunder exceed the effective annual rate
          of interest 

                                      27
<PAGE>
 
          on the "credit advanced", as defined therein, lawfully permitted under
          that section. The effective annual rate of interest shall be
          determined in accordance with Canadian generally accepted accounting
          principles and actuarial practices and principles over the term of the
          revolving term facility established hereby and, in the event of
          dispute, a certificate of a Fellow of the Canadian Institute of
          Actuaries appointed by the Agent (such appointee to be acceptable to
          the Borrower, acting reasonably) shall be conclusive for the purposes
          of such determination. Notwithstanding anything to the contrary
          contained in this Agreement, the Borrower in no event shall be obliged
          to make payments of interest in excess of any amount or rate which
          would be prohibited by law or would result in the receipt by the Agent
          or any Bank of interest at a criminal rate (as such terms are
          construed under the Criminal Code Canada)

2.14
     (a)  Arrangement Fee. The Borrower shall pay an arrangement fee to the
          ---------------                                                  
          Arranger for the Arranger's own account in accordance with the terms
          of a fee letter agreement between the Borrower and the Agent dated
          June 9, 1998 (the "Fee Letter");

     (b)  Facility Fees. The Borrower shall pay to the Agent, for the account of
          -------------                                                         
          each Bank, a facility fee in Canadian Dollars on the Aggregate
          Commitment, computed on a quarterly basis in arrears on the last
          Business Day of each calendar quarter, as calculated by the Agent, at
          a rate per annum equal to the Applicable Fee Amount. Such facility fee
          shall be payable regardless of utilization of the Commitments and
          shall accrue from the Closing Date to the Revolving Termination Date
          and shall be due and payable quarterly in arrears on the last Business
          Day of each calendar quarter commencing on June 30, 1998, through the
          Revolving Termination Date, with the final payment to be made on the
          Revolving Termination Date; provided that, in connection with any
                                      --------                             
          termination of Commitments under Section 2.9, the accrued facility fee
          calculated for the period ending on such date shall also be paid on
          the date of termination. The facility fees provided in this subsection
          shall accrue at all times after the above-mentioned commencement date,
          including at any time during which one or more conditions in Article V
          are not met.

     (c)  BA Stamping Fees. The Borrower shall pay to each Bank an acceptance or
          ----------------                                                      
          stamping fee determined in accordance with the pricing grid attached
          as Annex 1 hereto upon issuance by the Borrower and acceptance by such
          Bank of each Bankers' Acceptance, such fee to be calculated on the
          undiscounted face amount of each Bankers' Acceptance accepted by such
          Bank hereunder.  Such fee shall be paid upon the issuance by the
          Borrower and the acceptance by each Bank of each Bankers' Acceptance
          (by means of being deducted when determining the applicable BA
          Proceeds) and shall be based on the term of the applicable Bankers'
          Acceptance (computed for the period of time commencing from the date
          of acceptance thereof to but not including the date of maturity of
          such Bankers' Acceptance) on the basis of a 365 or 366 day year, as
          the case may be.

                                      28
<PAGE>
 
2.15      Computation of Fees and Interest.
          -------------------------------- 

     (a)  All computations of interest for Canadian Dollar Advances, U.S. Dollar
          Loans and all fees hereunder shall be made on the basis of a year of
          365 or 366 days, as the case may be, and actual days elapsed. All
          computations of interest on LIBOR Loans shall be made on the basis of
          a 360-day year and actual days elapsed (which results in more interest
          being paid than if computed on the basis of a 365-day year). Interest
          and fees shall accrue during each period during which interest or such
          fees are computed from the first day thereof to the last day thereof.

     (b)  Each determination of an interest rate or a U.S. or Canadian Dollar
          Equivalent Amount by the Agent shall be conclusive and binding on the
          Borrower and the Banks in the absence of manifest error.

     (c)  For the purposes of this Agreement, whenever any interest is
          calculated on the basis of a period of time (the "shorter period")
          other than a calendar year (whether on the basis of 360 days or
          otherwise) (referred to below as the "first rate") the annual rate of
          interest to which the first rate is equivalent, for purposes of the
          Interest Act (Canada), is the first rate multiplied by the actual
          number of days in the calendar year, (whether 365 or 366 as the case
          may be) in which such calculation is to be made and divided by the
          number of days in the shorter period.  It is understood and agreed by
          the Borrower and the Agent and Banks that, for purposes of this
          Agreement, the deemed re investment principle shall not apply to any
          calculation of interest payable under this Agreement or any Notes.

2.16      Payments by the Borrower.
          ------------------------ 

     (a)  All payments to be made by the Borrower shall be made without set-off,
          recoupment or counterclaim. Except as otherwise expressly provided
          herein, all payments by any Loan Party shall be made to the Agent for
          the account of the Banks at the Agent's Payment Office in U.S. Dollars
          for LIBOR Loans and U.S. Dollar Loans or Canadian Dollars for BA
          Advances and Canadian Dollar Advances and otherwise in the Applicable
          Currency.  Such payments shall be made in Same Day Funds, no later
          than 2:00 p.m. (Toronto Time) on the date specified herein. Any
          payment which is received by the Agent later than 2:00 p.m. (Toronto
          time), shall be deemed to have been received on the following Business
          Day and any applicable interest or fee shall continue to accrue.  The
          Agent will promptly, upon receipt of same, distribute to each Bank its
          Pro Rata Share (or other applicable share as expressly provided
          herein) of such payment in like funds received.

     (b)  Subject to the provisions set forth in the definition of "Interest
          Period" herein, whenever any payment is due on a day other than a
          Business Day, such payment shall be made on the following Business
          Day, and such extension of time shall in such case be included in the
          computation of interest or fees, as the case may be.

                                      29
<PAGE>
 
     (c)  Unless the Agent receives notice from the Borrower or the Borrower's
          Designee prior to the date on which any payment is due to the Banks
          that the Borrower will not make such payment in full as and when
          required, the Agent may assume that the Borrower has made such payment
          in full to the Agent on such date in Same Day Funds and the Agent may
          (but shall not be so required), in reliance upon such assumption,
          distribute to each Bank on such due date an amount equal to the amount
          then due such Bank. If and to the extent the Borrower has not made
          such payment in full to the Agent, each Bank shall repay to the Agent
          on demand such amount distributed to such Bank, together with interest
          thereon at the Federal Funds Rate for each day from the date such
          amount is distributed to such Bank until the date repaid.

2.17      Payments by the Banks to the Agent.
          ---------------------------------- 

     (a)  Unless the Agent receives notice from a Bank on or prior to the Loan
          Availability Date or, with respect to any Borrowing after the Loan
          Availability Date, at least one Business Day prior to the date of such
          Borrowing, that such Bank will not make available as and when required
          hereunder to the Agent, for the account of the Borrower the amount of
          that Bank's Pro Rata Share of the Borrowing, the Agent may assume that
          each Bank has made such amount available to the Agent in Same Day
          Funds on the Borrowing Date and the Agent may (but shall not be so
          required), in reliance upon such assumption, make available to the
          Borrower on such date a corresponding amount. If and to the extent any
          Bank shall not have made its full amount available to the Agent in
          Same Day Funds and the Agent in such circumstances has made available
          to the Borrower such amount, that Bank shall on the Business Day
          following such Borrowing Date make such amount available to the Agent,
          together with interest at the Federal Funds Rate for each day during
          such period. A notice of the Agent submitted to any Bank with respect
          to amounts owing under this subsection 2.17(a) shall be conclusive,
          absent manifest error. If such amount is so made available, such
          payment to the Agent shall constitute such Bank's Loan on the date of
          Borrowing for all purposes of this Agreement. If such amount is not
          made available to the Agent on the Business Day following the
          Borrowing Date, the Agent will notify the Borrower's Designee of such
          failure to fund and, upon demand by the Agent, the Borrower shall pay
          such amount to the Agent for the Agent's account, together with
          interest thereon for each day elapsed since the date of such
          Borrowing, at a rate per annum equal to (except in the case of BA
          Advances) the interest rate applicable at the time to the Loans
          comprising such Borrowing and in the case of BA Advances, at a rate
          per annum equal to the sum of the CDOR BA Rate and BA Stamping Fee
          used to determine the amount of BA Proceeds of such BA Advances.

     (b)  The failure of any Bank to make any Loan on any Borrowing Date shall
          not relieve any other Bank of any obligation hereunder to make a Loan
          on such Borrowing Date, but no Bank shall be responsible for the
          failure of any other Bank); to make the Loan to be made by such other
          Bank on any Borrowing Date.

2.18    Sharing of Payments, Etc.  If, other than as expressly provided
        -------------------------                                      
elsewhere herein, any Bank shall obtain on account of the Loans made by it any
payment (whether voluntary, involuntary, through the exercise of any right of
set-off, or otherwise) in excess of its ratable share (or other share
contemplated hereunder), such Bank shall immediately (a) notify the Agent of
such fact, and (b) purchase from the other Banks such participations in the
Loans made by them as shall be necessary to cause such purchasing Bank to share
the excess payment pro rata with each of the other Banks; provided, however,
                                                          --------  ------- 
that if all or any portion of such excess payment is thereafter recovered from
the purchasing Bank, such purchase shall to that extent be rescinded and each
other Bank shall repay to the purchasing Bank the purchase price paid therefor,
together with an amount equal to such paying Bank's ratable share (according to
the proportion of (i) the amount of such paying Bank's required repayment to
(ii) the total amount so recovered from the purchasing Bank) of any interest or
other amount paid or payable by the purchasing Bank in respect of the total
amount so recovered. Each Loan Party agrees that any Bank so purchasing a
participation from another Bank may, to the fullest extent permitted by law,
exercise all its rights of payment (including the right of set-off, but subject
to Section 11.10) with respect to such participation as fully as if such Bank
were the direct creditor of such Loan Party in the amount of such participation.
The Agent will keep records (which shall be conclusive and binding in the
absence of manifest error) of participations purchased under this Section and
will in each case notify the Banks following any such purchases or repayments.

2.19      The Borrower's Designee.
          ----------------------- 

     (a)  The Borrower hereby irrevocably appoints, designates and authorizes
          the Borrower's Designee to take such action on its behalf under the
          provisions of this Agreement and each other Loan Document and to
          exercise such powers and perform such duties as are expressly
          delegated to it by the terms of this Agreement or any other Loan
          Document, together with such powers as are reasonably incidental
          thereto. The Borrower's Designee may execute any of its duties under
          this Agreement or any other Loan Document by or through agents,
          employees or attorneys-in-fact.

     (b)  The Borrower's Designee shall promptly forward to the Agent or the
          Borrower, as appropriate, all notices, certificates, financial
          statements and reports received by it in the performance of its duties
          hereunder.

     (c)  The Borrower may, upon 30 days' notice to and with the consent of the
          Agent (which consent shall not be unreasonably withheld), appoint
          another person to act as Borrower's Designee and upon such appointment
          such successor Borrower's Designee shall succeed to all the
          appointment, powers and duties of the retiring Borrower's Designee and
          the term "Borrower's Designee" shall mean such successor designee and
          the retiring Borrower's Designee's rights, powers and duties as
          Borrower's Designee shall be terminated.

     (d)  The Borrower's Designee shall perform its duties hereunder and under
          the other Loan Documents on behalf of the Borrower. The action of the
          Borrower's Designee shall in each case bind the Borrower, and any
          action taken by the 

                                      31
<PAGE>
 
          Borrower's Designee in the name of the Borrower pursuant to this
          Agreement or any other Loan Document shall bind the Borrower, whether
          or not such action has been duly authorized by the Borrower.

     (e)  Any agreement of the Agent and the Banks herein with respect to the
          Borrower's Designee is solely for the convenience and at the request
          of the Borrower. The Agent and the Banks shall be entitled to rely on
          the authority of any Person purporting to be a Person authorized by
          the Borrower to act on behalf of the Borrower's Designee and the Agent
          and the Banks shall not have any liability to the Borrower or other
          Person on account of any action taken or not taken by the Agent or the
          Banks in reliance thereon.

     (f)  Nothing contained in this section 2.19 and no exercise of powers by
          the Borrower's Designee shall relieve the Borrower from its
          indebtedness, liabilities and obligations to the Agent and the Banks
          hereunder.

[ORIGINAL ARTICLE III INTENTIONALLY DELETED]

3.1    Bankers' Acceptances
       --------------------

     (a)  No Bank shall accept any bill of exchange drawn by the Borrower to be
          a Bankers' Acceptance hereunder which:

         (i)   is drawn on or which matures on a day which is not a Business
               Day;

         (ii)  matures subsequent to the Revolving Termination Date;

         (iii) has a term less than 30 or exceeding 180 days;

         (iv)  is denominated in any currency other than Canadian Dollars;

         (v)   is not in an applicable Minimum Amount;

               normal course of its business; or

         (vii) in respect of which the Borrower has not then paid the
               applicable acceptance or stamping fee.

     (b)  The Borrower hereby waives presentment for payment and any other
          defence to payment of any amounts due to any Bank in respect of
          Bankers' Acceptances and renounces, and shall not claim or request or
          require such Bank to claim, any days of grace for the payment of any
          Bankers' Acceptances.

     (c)  All Bankers' Acceptances accepted by each Bank shall be purchased by
          such Bank at the applicable CDOR BA Rate from the Borrower for an
          amount equal to the BA Proceeds.  Any Bank may at any time and from
          time to time hold, sell, rediscount or otherwise dispose of any or all
          Bankers' Acceptances accepted and purchased by it.

     (d)  The Borrower hereby unconditionally agrees to pay to each Bank to such
          address as it may direct on the maturity date (whether at stated
          maturity, by acceleration hereunder or otherwise) of each Bankers'
          Acceptance accepted by such Bank the aggregate undiscounted face
          amount of each then maturing Bankers' Acceptance and in this regard,
          the Borrower hereby authorizes each Bank to debit any account of the
          Borrower with such Bank with the amount(s) required to pay the full
          undiscounted face amount of such Bankers' Acceptance, notwithstanding
          the fact that such Bankers' Acceptance may be held by such Bank in its
          own right at maturity.  The obligation of the Borrower to reimburse
          and pay each Bank for then maturing Bankers' Acceptances may be
          satisfied (provided no Event of Default has occurred and is subsisting
          or no event has occurred which, but for notice being given or grace
          periods expiring (or both) would be an Event of Default) in the manner
          contemplated by subsection 2.4(d) above.  The Borrower acknowledges
          and agrees that any and all security now or hereafter held by the
          Agent or any Bank for the payment of all or any portion of the
          Obligations shall be held as continuing collateral security for, among
          other things, repayment of the Obligations to the Banks in respect of
          all Bankers' Acceptances.

     (e)  To facilitate the acceptance by each Bank of bills of exchange to be
          Bankers' Acceptances as contemplated by this Agreement, the Borrower
          shall deliver to each Bank, as it may request, a Bankers' Acceptance
          Power of Attorney in the form of Exhibit C attached hereto.

     (f)  Subject to the following subparagraph (g), no prepayment of any
          Bankers' Acceptance shall be made by the Borrower to any Bank prior to
          the maturity date of such Bankers' Acceptance.

     (g)  Upon the occurrence of an Event of Default, notwithstanding the date
          of maturity of any outstanding Bankers' Acceptances, the Borrower
          shall, if the Majority Banks so require,  pay to the Agent forthwith
          upon demand made to the Borrower's Designee, an amount equivalent to
          the amount or amounts required to pay on maturity, the undiscounted
          face amount of all outstanding Bankers' Acceptances which the Banks
          are required to honour and, all such amounts shall be deposited into
          an interest-bearing cash collateral account to be held by the Agent as
          additional security for payment of the undiscounted face amount of
          such outstanding Bankers' Acceptances upon maturity, and accrued
          interest on such cash collateral, at the option of the Agent, may
          either be credited to the Borrower or applied against any Obligations
          which continue to be outstanding.

                                      33

     (h)  If the Agent determines in good faith and notifies the Borrower in
          writing that by reason of circumstances affecting the Canadian money
          market (after having discussed those circumstances with the Borrower)
          there is no market for Bankers' Acceptances, then the right of the
          Borrower to request a Loan in the form of Bankers' Acceptances shall
          be suspended until the Agent, acting reasonably, determines that
          circumstances causing such suspension no longer exist and the Agent so
          notifies the Borrower and until then any Notice of Borrowing with
          respect to any Bankers' Acceptances which is outstanding shall be
          cancelled and the Loan requested therein shall, at the option of the
          Borrower, either not be made or be made as a Canadian Dollar Advance.

3.2       BA Advance Procedures.
          --------------------- 

     (a)  The Agent, promptly following receipt of a Notice of Borrowing
          pursuant to Section 2.3 requesting a BA Advance, shall advise each
          Bank of the aggregate face amount and the term of the Bankers'
          Acceptances to be accepted by it (which terms shall be identical for
          all Banks).  The aggregate face amount of Bankers' Acceptances to be
          accepted by a Bank shall be determined by the Agent by reference to
          the Pro Rata Share of each Bank, except that if the face amount of a
          Bankers' Acceptance would not be a whole multiple of $100,000, the
          face amount shall be increased or reduced by the Agent in its sole and
          unfettered discretion to the nearest whole multiple of $100,000.

     (b)  Each Bank shall purchase such Bankers' Acceptances for an amount equal
          to the BA Proceeds.  Each Bank shall transfer to the Agent, on each
          Borrowing Date, Canadian Dollars in Same Day Funds in an aggregate
          amount equal to the BA Proceeds for the Bankers' Acceptances accepted
          and purchased by such Bank on such date, net of the amount required to
          pay any of its previously accepted Bankers' Acceptances or other Loans
          that are maturing on the applicable Borrowing Date.

     (c)  If the Agent determines that all conditions precedent to an advance
          specified in this Agreement have been met, it shall advance to the
          Borrower the amount delivered by each Bank in the manner contemplated
          in subsection 2.3(c) for other Loans, but if the conditions precedent
          to such advance have not been met by 3:00 p.m. (Toronto time) on a
          Borrowing Date, it shall invest the funds in an overnight investment
          as orally instructed by each Bank until such time as the advance is
          made.

     (d)  If the proposed Depository Bills and Notes Act (Canada) is enacted in
          substantially the terms of Bill C-90 to which first reading was given
          in the House of Commons of Canada on March 13, 1997 (reintroduced as
          Bill S-9) on December 3, 1997) and if at that time or any time
          thereafter the Agent, the Banks and the Borrower determine that any
          Bankers' Acceptances accepted by any Bank under this Agreement after
          the effective date of that Act and after clearing services acceptable
          to the Borrower and the Agent are available shall be "depository
          bills" to which the Act applies then all such Bankers' Acceptances

                                      34
<PAGE>
 
          thereafter shall be issued in the form of a "depository bill" and
          deposited with a "clearing house", as those terms are defined in Bill
          C-90.  At that time the Agent shall, in consultation with the
          Borrower, establish and notify the Borrower of such procedures,
          consistent with the terms of this Agreement and the requirements of
          such Act as are reasonably necessary to accomplish the parties'
          intention.

                                   ARTICLE IV
                                   ----------

                     TAXES, YIELD PROTECTION AND ILLEGALITY
                     --------------------------------------

4.1       Taxes.
          ----- 

     (a)  Any and all payments by each Loan Party to each Bank or the Agent
          under this Agreement and any other Loan Document shall be made free
          and clear of, and without deduction or withholding for, any Taxes.

     (b)  If any Loan Party shall be required by law to deduct or withhold any
          Taxes and Further Taxes from or in respect of any sum payable
          hereunder to any Bank or the Agent, then:

          (i)   the sum payable shall be increased as necessary so that, after
                making all required deductions and withholdings (including
                deductions and withholdings applicable to additional sums
                payable under this Section), such Bank or the Agent, as the case
                may be, receives an amount equal to the sum it would have
                received had no such deductions or withholdings been made;

          (ii)  such Loan Party shall make such deductions and withholdings;

          (iii) such Loan Party shall pay the full amount deducted or withheld
                to the relevant taxing authority or other authority in
                accordance with applicable law; and

          (iv)  such Loan Party shall also pay to each Bank or the Agent for the
                account of such Bank, at the time interest is paid, Further
                Taxes in the amount that the respective Bank specifies as
                necessary to preserve the after-tax yield such Bank would have
                received if such Taxes or Further Taxes had not been imposed.

     (c)  Each Loan Party agrees to indemnify and hold harmless each Bank and
          the Agent for the full amount of (i) Taxes and (ii) Further Taxes in
          the amount that the respective Bank specifies as necessary to preserve
          the after-tax yield such Bank would have received if such Taxes or
          Further Taxes had not been imposed, and any liability (including
          penalties, interest, additions to tax and expenses) arising therefrom
          or with respect thereto, whether or not such Taxes or Further Taxes
          were correctly or legally asserted. Payment under this indemnification
          shall be 

                                      35
<PAGE>
 
          made within 30 days after the date such Bank or the Agent makes
          written demand therefor, provided, however, that such Loan Party shall
          not be obligated to make a payment to the Bank or the Agent (as the
          case may be) pursuant to this Section in respect of penalties,
          interest and other liabilities attributable to any Taxes or Further
          Taxes, if (A) such penalties, interest and other liabilities have
          accrued after such Loan Party has indemnified or paid any additional
          amount pursuant to this Section, or (B) such penalties, interest and
          other liabilities are attributable to the gross negligence or willful
          misconduct of the Bank. After the Bank or the Agent (as the case may
          be) learns of the imposition of Taxes or Further Taxes, such Bank and
          the Agent will act in good faith to promptly notify the relevant Loan
          Party of its obligations hereunder.

     (d)  Within 30 days after the date of any payment by any Loan Party of
          Taxes or Further Taxes, the Borrower's Designee shall furnish to each
          Bank or the Agent the original or a certified copy of a receipt
          evidencing payment thereof, or other evidence of payment satisfactory
          to such Bank or the Agent.

     (e)  If a Bank receives a refund in respect of any Taxes or Further Taxes
          as to which it has been indemnified by any Loan Party pursuant to this
          Section, or with respect to which any Loan Party has paid additional
          amounts pursuant to this Section, it shall within 30 days from the
          date of receipt of such refund pay over the amount of such refund
          (including any interest paid or credited by the relevant taxing
          authority with respect to such refund) to such Loan Party (but only to
          the extent of indemnity payments made, or additional amounts paid, by
          the Loan Party under the Section with respect to the Taxes or Further
          Taxes giving rise to such refund); provided, however, that the Loan
                                             --------  -------               
          Party, upon the request of such Bank agrees to repay the amount paid
          over to the Loan Party to such Bank in the event such Bank is required
          to repay such refund to such relevant authority.

     (f)  For any period with respect to which a Bank ceases to be a resident of
          Canada (except where such Bank has become a non-resident of Canada due
          to a change in treaty, law or regulation occurring subsequent to the
          date of this Agreement), such Bank shall not be entitled to
          indemnification under this Section 4.1 with respect to Taxes imposed
          by any Governmental Authority of Canada (or any political division
          thereof) as a result of such non-residency; provided that if a Bank,
                                                      --------                
          which is otherwise exempt from withholding tax, becomes subject to
          Taxes, the Loan Parties shall take such steps as such Bank shall
          reasonably request, at the Bank's expense, to assist such Bank to
          recover such Taxes (and provided further that if such Bank becomes a
          resident of a jurisdiction other than Canada, this indemnity in favour
          of such Bank for withholding tax gross up shall not exceed 10% of the
          amount of any payment in respect of which a withholding is required).

     (h)  Each Bank and the Agent agrees that it will (i) take all reasonable
          actions reasonably requested by the Loan Parties that are without risk
          or material cost to such Bank or the Agent (as the case may be) to
          maintain all exemptions, available to it from withholding taxes
          (whether available by treaty or existing 

                                      36
<PAGE>
 
          administrative waiver), including the filing of any certificate or
          document if such filing-would avoid the need for or reduce the amount
          of any such additional amounts payable to or for the account of such
          Bank or the Agent (as the case may be) pursuant to this Section 4.1,
          and (ii) to the extent reasonable and without material cost to it,
          otherwise cooperate with the relevant Loan Party to minimize any
          amount payable by such Loan Party under this Section.

4.2       Illegality. If any Bank determines that the introduction of any
          ----------                                                     
Requirement of Law, or any change in any Requirement of Law, or in the
interpretation or administration of any Requirement of Law, has made it
unlawful, or that any central bank or other Governmental Authority has asserted
that it is unlawful, for any Bank or its applicable Lending Office to make LIBOR
Loans, then, in such event, the affected Bank shall give notice thereof to the
Borrower's Designee (through the Agent). Thereafter, (i) any obligation of that
Bank to make LIBOR Loans (or convert Loans into LIBOR Loans) shall be suspended
until such Bank notifies the Agent and the Borrower's Designee that the
circumstances giving rise to such determination no longer exist, (ii) to the
extent that such determination relates to a LIBOR Loan then being requested by
the Borrower pursuant to a Notice of Borrowing or a Notice of
Conversion/Continuation, such Bank shall make such Loan as (or convert such Loan
to) a U.S. Dollar Loan and (iii) any outstanding LIBOR Loans of such affected
Bank shall convert into U.S. Dollar Loans either on the last day of the Interest
Period thereof, if such Bank may lawfully continue to maintain such LIBOR Loans
to such day, or (subject to Section 4.4) immediately, if such Bank may not
lawfully continue to maintain such LIBOR Loan.

4.3       Increased Costs and Reduction of Return.
          --------------------------------------- 

     (a)  If any Bank determines that, due to either (i) the introduction after
          the date hereof of or any change after the date hereof in or in the
          interpretation of any law or regulation or (ii) the compliance by that
          Bank with any guideline or request from any central bank or other
          Governmental Authority (whether or not having the force of law), there
          shall be any increase in the cost to such Bank of agreeing to make or
          making, funding or maintaining any Loans, then such Bank shall
          promptly give notice to the Borrower's Designee and the Borrower shall
          pay to such Bank, within 15 days of receipt of the notice referred to
          above, such additional amounts (in the form of an increased rate of,
          or a different method of calculating, interest or otherwise as such
          Bank in its sole discretion shall determine) as shall be required to
          compensate such Bank for such increased costs or reductions in amounts
          received or receivable hereunder. To the extent the notice required by
          the preceding sentence and relating to the costs arising under this
          Section 4.3 is given by any Bank more than 90 days after the
          occurrence of the event giving rise to the additional costs of the
          type described in this Section 4.3, such Bank shall not be entitled to
          compensation under this Section 4.3 for any amounts incurred or
          accrued prior to the giving of such notice to the Borrower's Designee.

                                      37
<PAGE>
 
     (b)  If any Bank shall have determined that (i) the introduction after the
          date hereof of any Capital Adequacy Regulation, (ii) any change after
          the date hereof in any Capital Adequacy Regulation, or (iii) any
          change after the date hereof in the interpretation or administration
          of any Capital Adequacy Regulation by any central bank or other
          Governmental Authority charged with the interpretation or
          administration thereof, affects or would affect the amount of capital
          required or expected to be maintained by such Bank or any corporation
          controlling such Bank and (taking into consideration such Bank's or
          such corporation's policies with respect to capital adequacy and such
          Bank's desired return on capital) determines that the amount of such
          capital is increased as a consequence of its Commitment, loans,
          credits or obligations under this Agreement, the Borrower agrees to
          pay such Bank, within 15 days of the receipt of the notice referred to
          below, such additional amounts as shall be required to compensate such
          Bank for the increased cost to such Bank as a result of such increase
          of capital. In determining such additional amounts, each Bank will act
          reasonably and in good faith and will use averaging and attribution
          methods which are reasonable, provided that such Bank's determination
          of compensation under this subsection 4.3(b) shall, absent manifest
          error, be final and conclusive and binding on all parties hereto. Each
          Bank, upon determining that additional amounts will be payable
          pursuant to this subsection 4.3(b), will give prompt written notice
          thereof to the Borrower's Designee, although the failure to give any
          such notice shall not release or diminish the Borrower's obligations
          to pay additional amounts pursuant to this subsection 4.3(b). To the
          extent the notice required by the immediately preceding sentence is
          given by any Bank more than 90 days after the occurrence of the event
          giving rise to the additional costs of the type described in this
          subsection 4.3(b), such Bank shall not be entitled to compensation
          under this subsection 4.3(b) for any amounts incurred or accrued prior
          to the giving of such notice to the Borrower's Designee.

4.4       Funding Losses. The Borrower shall reimburse each Bank and hold each
          --------------                                                      
Bank harmless, within 15 days of written request by such Bank to the Borrower's
Designee (which request shall set forth in reasonable detail the basis for
requesting and the calculation of the amount of such compensation), from any
loss or expense which the Bank may sustain or incur as a consequence of:

     (a)  the failure of the Borrower to make on a timely basis any payment of
          principal of any LIBOR Loan;

     (b)  the failure of the Borrower to borrow, continue or convert a Loan
          after the Borrower's Designee has given (or is deemed to have given) a
          Notice of Borrowing or a Notice of Conversion/Continuation;

     (c)  the failure of the Borrower to make any prepayment in accordance with
          any notice delivered under Sections 2.9 or 2.10;

                                      38
<PAGE>
 
     (d)  the prepayment (including pursuant to Sections 2.9, 2.10 or 4.8) or
          other payment (including after acceleration thereof) of a LIBOR Loan
          on a day that is not the last day of the relevant Interest Period or
          of a BA Advance on a day that is not the maturity date of such
          Bankers' Acceptance; or

     (e)  the conversion under Section 2.4 of any LIBOR Loan to a U.S. Dollar
          Loan or any other type of Loan on a day that is not the last day of
          the relevant Interest Period;

including any such loss or expense arising from the liquidation or re-employment
of funds obtained by it to maintain its LIBOR Loans or BA Advances and from fees
payable to terminate the deposits from which such funds were obtained and from
charges relating thereto (but excluding any loss of anticipated profits).

4.5       Inability to Determine Rates. If the Agent or the Banks shall
          ----------------------------                                 
determine that for any reason adequate and reasonable means do not exist for
determining the Offshore Rate for any requested Interest Period with respect to
a proposed borrowing of LIBOR Loans or conversion or continuation of LIBOR
Loans, or that the Offshore Rate applicable pursuant hereto for any requested
Interest Period with respect to a proposed borrowing of LIBOR Loans, or a
conversion into or continuation of LIBOR Loans does not adequately and fairly
reflect the cost to the Banks of funding such Loans, the Agent will promptly so
notify the Borrower's Designee and each Bank. Thereafter, the obligation of the
Banks to make or maintain LIBOR Loans hereunder shall be suspended until the
Agent upon the instructions of the Banks revokes such notice in writing. Upon
receipt of such notice, the Borrower's Designee may revoke any Notice of
Borrowing or Notice of Conversion/Continuation then submitted by it. In the case
of any LIBOR Loans, if the Borrower's Designee does not revoke such Notice, the
Banks shall make, convert or continue the Loans, as requested by the Borrower's
Designee, in the amount specified in the applicable notice submitted by the
Borrower's Designee, but such Loans shall be made, converted or continued as
U.S. Dollar Loans instead of LIBOR Loans.

4.6       Reserves on LIBOR Loans. The Borrower shall pay to each Bank, as long
          -----------------------                                              
as such Bank shall be required under regulations of the FRB or the Bank of
Canada to maintain reserves with respect to liabilities or assets consisting of
or including LIBOR Loans under any applicable regulations of the central bank or
other relevant Governmental Authority, additional costs on the unpaid principal
amount of each LIBOR Loan equal to the actual costs of such reserves allocated
to such Loan by the Bank (as determined by such Bank in good faith, which
determination shall be conclusive), payable on each date on which interest is
payable on such Loan, provided such Bank shall promptly give notice to the
                      --------                                            
Borrower's Designee and to the Agent of such additional cost. Thereafter the
Borrower shall pay such Bank, within 15 days of receipt of such notice, such
additional amounts (in the form of an increased rate of, or a different method
of calculating, interest or otherwise as such Bank in its sole discretion shall

routine public disclosure concerning the Borrower or either of the Guarantors),
any Governmental Authority is necessary or required in connection with the
execution, delivery or performance by, or enforcement against, any Loan Party of
the Agreement or any other Loan Document.

6.4       Binding Effect.  This Agreement and each other Loan Document to which
          --------------

          applicable provisions of ERISA, the Code and all other U.S. or
          Canadian federal, or state or provincial law. Each Pension Plan which
          is intended to qualify under Section 401(a) of the Code has received a
          favorable determination letter from the IRS and, to the best knowledge
          of JM, nothing has occurred which would cause the loss of such

          with respect to its Pension Plans) threatened claims, actions or

          violation of the fiduciary responsibility rules with respect to any
          Plan.

          (ii) no Pension Plan has any Unfunded Pension Liability; (iii) neither
          JM nor any ERISA Affiliate nor the Borrower (with respect to itself)
          has incurred, or reasonably expects to incur, any liability under
          Title IV of ERISA with respect to any Pension Plan (other than
          premiums due and not delinquent under Section 4007 of ERISA) or any
          breach or violation of applicable Canadian law (except for any such
          breach or violation of applicable Canadian law that would not
          reasonably be expected to have a Material Adverse Effect) (iv) neither
          JM nor any ERISA Affiliate nor the Borrower (with respect to itself)
          has incurred, or reasonably expects to incur, any liability (and no
          event has occurred which, with the giving of notice under Section 4219
          of ERISA, would result in such liability) under Section 4201 or 4243
          of ERISA with respect to a Multiemployer Plan; and (v) neither JM nor
          any ERISA Affiliate has engaged in a transaction that could be subject
          to Section 4069 or 4212(c) - of ERISA.

6.9       Title to Properties; Liens.  JM and each Material Subsidiary,
          --------------------------                                   
including the Borrower, has good record and marketable title in fee simple to,
or valid leasehold interests in (or the equivalent in the applicable
jurisdiction), all real property necessary or used in the ordinary conduct of
their respective businesses, except for any Permitted Liens and such defects in
or other differences from such required title or interest as would not,
individually or in the aggregate, reasonably be expected to have a Material
Adverse Effect.

6.10      Taxes.  JM and each of its Subsidiaries, including the Borrower,
          -----                                                           
have filed all Federal, provincial, state and other material tax returns and
reports required to be filed, and have paid all Federal, provincial, state and
other material taxes, assessments, fees and other governmental charges levied or
imposed upon them or their properties, income or assets otherwise due and
payable, (i) except those which are being contested in good faith by appropriate
proceedings or (ii) where the failure to so file or pay would not reasonably be
expected to have a Material Adverse Effect.

6.11      Financial Condition.
          ------------------- 

     (a)  The audited consolidated balance sheet of JM and its Subsidiaries
          dated December 31, 1997 and the unaudited balance sheet of the
          Borrower dated December 31, 1997, and each of the related consolidated
          statements of income or operations, stockholders' equity and cash
          flows (other than cash flows for the Borrower, which have not been
          prepared) for the fiscal periods ended on that date: (i) were prepared
          in accordance with GAAP consistently applied throughout the period
          covered thereby, except as otherwise expressly noted therein and
          except for the absence of footnotes in the case of the Borrower's
          financial statements and (ii) are complete and accurate in all
          material respects and fairly present the financial condition of JM and
          its Subsidiaries or the Borrower, as the case may be, as of the date
          thereof and results of operations and (except in the case of the
          Borrower) cash flows for the period covered thereby.

     (b)  Since December 31, 1997, there has been no Material Adverse Effect.

6.12      Environmental Matters.  Except as disclosed in JM's Form 10-K with
          ---------------------                                             
respect to its fiscal year ended December 31, 1997, JM conducts in the ordinary
course of business a review of the effect of existing Environmental Laws and
existing Environmental Claims on the business, operations and properties of JM
and its Subsidiaries, including the Borrower, and as a result thereof JM has
reasonably concluded that such Environmental Laws and Environmental Claims would
not, individually or in the aggregate, reasonably be expected to have a Material
Adverse Effect.

6.13      Regulated Entities.  None of the Loan Parties or any Subsidiary of
          ------------------

Investment Company Act of 1940. None of the Loan Parties is subject to
regulation under the Public Utility Holding Company Act of 1935, the Federal
Power Act, the Interstate Commerce Act, any state public utilities code, or any
other U.S. or Canadian, Federal, provincial or state statute or regulation
limiting its ability to incur Indebtedness.

6.14      Copyrights, Patents, Trademarks and Licenses, Etc.  JM and its
          --------------------------------------------------            
Subsidiaries, including the Borrower, own or are licensed or otherwise have the
right to use all of the patents, trademarks, service marks, trade names,
copyrights, contractual franchises, authorizations and other-rights that are
reasonably necessary for the operation of their respective businesses, without
any known conflict with the rights of any other Person, except where the failure
to so own, license or otherwise have the right to use any of the foregoing would
not, alone or in the aggregate, be reasonably expected to have a Material
Adverse Effect. To the best knowledge of JM (i) no product, process, method,
substance, part or other material now employed, or now contemplated to be
employed, by JM or any Subsidiary infringes upon any rights held by any other
Person, (ii) except as specifically disclosed in the JM's Form 10-K for the
fiscal year ended December 31, 1997, no claim or litigation regarding any of the
foregoing is pending or, to the best knowledge of JM, threatened, and (iii) no
patent, invention, device, application, principle or any statute, law, rule,
regulation, standard or code is pending or, to the best knowledge of JM,
proposed, which, in any such case, would reasonably be expected to have a
Material Adverse Effect described in clauses (i), (ii) or (iii).

          ---------                                                      
including the Borrower, are insured, with financially sound and reputable
insurance companies or through JM's own program of self-insurance, in such
amounts, with such deductibles and covering such risks as are customary for
companies engaged in similar businesses and owning similar properties in
localities where JM or such Subsidiary operates.

6.16      Full Disclosure.  The factual information (other than any projections
          ---------------

conditions, properties and prospects of JM and its Subsidiaries is, taken as a

was supplied to the Agent and the Banks and, taken as a whole, does not omit any
material fact required to be stated or necessary to make any statements made, in
light of the circumstances under which they are made, not misleading. All
projections and pro forma financial information are based on good faith
assumptions and estimates that each Loan Party believed reasonable at the time
made. However, because financial projections are based on estimates and
assumptions about circumstances and events that have not yet taken place, actual
results during the period covered by such projections may differ materially from
the projected results.

6.17      Year 2000.  JM has reviewed the areas within its consolidated business
          ---------                                                             
and operations that could be adversely affected by, and has developed or is
developing a plan to address on a timely basis, the "Year 2000 Problem" (that
is, the risk that computer applications used by JM and its Subsidiaries may be
unable to recognize and perform properly date-sensitive functions involving
certain dates prior to and any date after December 31, 1999).  Based on such
review and plan, JM reasonably believes that the "Year 2000 Problem" will not
have a Material Adverse Effect.

request of, or may, with the consent of, the Majority Banks, do any or all of
the following:

     (a)  declare the obligation of each Bank to make, continue, rollover or
          convert any Loans hereunder to be terminated, whereupon such
          obligations and each Bank's Commitment shall be terminated and the
          Borrower shall thereupon and thereafter not be entitled to request any

                                   THE AGENT
                                   ---------

10.1      Appointment and Authorization; "Agent".  Each Bank hereby irrevocably
          --------------------------------------                               
(subject to Section 10.9) appoints, designates and authorizes the Agent to take
such action on its behalf under the provisions of this Agreement and each other
Loan Document and to exercise such powers and perform such duties as are
expressly delegated to it by the terms of this Agreement or any other Loan
Document, together with such powers as are reasonably incidental thereto.
Notwithstanding any provision to the contrary contained elsewhere in this
Agreement or in any other Loan Document, the Agent shall not have any duties or
responsibilities, except those expressly set forth herein, nor shall the Agent
have or be deemed to have any fiduciary relationship with any Bank, and no
implied covenants, functions, responsibilities duties, obligations or
liabilities shall be read into this Agreement or any other Loan Document or
otherwise exist against the Agent. Without limiting the generality of the
foregoing sentence, the use of the term "agent" in this Agreement with reference
to the Agent is not intended to connote any fiduciary or other implied (or
express) obligations arising under agency doctrine of any applicable law.
Instead, such term is used merely as a matter of market custom, and is intended
to create or reflect only an administrative relationship between independent
contracting parties.

                                      61

10.2      Delegation of Duties.  The Agent may execute any of its duties under
          --------------------                                                
this Agreement or any other Loan Document by or through agents, employees or
attorneys-in-fact and shall be entitled to advice of counsel concerning all
matters pertaining to such duties. The Agent shall not be responsible for the
negligence or misconduct of any agent or attorney-in-fact that it selects with
reasonable care.

10.3      Liability of Agent.  None of the Agent-Related Persons shall (i) be
          ------------------                                                 
liable for any action taken or omitted to be taken by any of them under or in
connection with this Agreement or any other Loan Document or the transactions
contemplated hereby (except for its own gross negligence or willful misconduct),
or (ii) be responsible in any manner to any of the Banks for any recital,
statement, representation or warranty made by any of the Loan Parties, the
Borrower's Designee or any Subsidiary or Affiliate of any of the Loan Parties,
or any officer thereof, contained in this Agreement or in any other Loan
Document, or in any certificate, report, statement or other document referred to
or provided for in, or received by the Agent under or in connection with, this
Agreement or any other Loan Document, or the validity, effectiveness,
genuineness, enforceability or sufficiency of this Agreement or any other Loan
Document, or for any failure of any of the Loan Parties or any other party to
any Loan Document to perform its obligations hereunder or thereunder. No Agent-
Related Person shall be under any obligation to any Bank to ascertain or to
inquire as to the observance or performance of any of the agreements contained
in, or conditions of, this Agreement or any other Loan Document, or to inspect
the properties, books or records of the Loan Parties or any of their respective
Subsidiaries or Affiliates.

10.4      Reliance by Agent.
          ----------------- 

     (a)  The Agent shall be entitled to rely, and shall be fully protected in
          relying, upon any writing, resolution, notice, consent, certificate,
          affidavit, letter, telegram, facsimile, telex or telephone message,
          statement or other document or conversation believed by it to be
          genuine and correct and to have been signed, sent or made by the
          proper Person or Persons, and upon advice and statements of legal
          counsel (including counsel to any of the Loan Parties), independent
          accountants and other experts selected by the Agent. The Agent shall
          be fully justified in failing or refusing to take any action under
          this Agreement or any other Loan Document unless it shall first
          receive such advice or concurrence of the Majority Banks as it deems
          appropriate and, if it so requests, it shall first be indemnified to
          its satisfaction by the Banks against any and all liability and
          expense which may be incurred by it by reason of taking or continuing
          to take any such action. The Agent shall in all cases be fully
          protected in acting, or in refraining from acting, under this
          Agreement or any other Loan Document in accordance with a request or
          consent of the Majority Banks and such request and any action taken or
          failure to act pursuant thereto shall be binding upon all of the
          Banks.

     (b)  For purposes of determining compliance with the conditions specified
          in Section 5.1, each Bank that has executed this Agreement shall be
          deemed to have consented to, approved or accepted or to be satisfied
          with, each document or other matter either sent (or made available) by
          the Agent to such Bank for consent, approval, acceptance or
          satisfaction, or required thereunder to be consented to or approved by
          or acceptable or satisfactory to such Bank.

10.5      Notice of Default.  The Agent shall not be deemed to have knowledge or
          -----------------                                                     
notice of the occurrence of any Default or Event of Default, except with respect
to defaults in the payment of principal, interest and fees required to be paid
to the Agent for the account of the Banks, unless the Agent shall have received
written notice from a Bank, the Borrower's Designee or any other Loan Party
referring to this Agreement, describing such Default or Event of Default and
stating that such notice is a "notice of default". The Agent will notify the
Banks of its receipt of any such notice. The Agent shall take such action with
respect to such Default or Event of Default as may be requested by the Majority
Banks in accordance with Article IX; provided, however, that unless and until
                                     --------  -------                       
the Agent has received any such request, the Agent may (but shall not be
obligated to) take such action, or refrain from taking such action, with respect
to such Default or Event of Default as it shall deem advisable or in the best
interest of the Banks.

10.6      Credit Decision.  Each Bank acknowledges that none of the Agent-
          ---------------                                                
Related Persons has made any representation or warranty to it, and that no act
by the Agent hereinafter taken, including any review of the affairs of each Loan
Party and its Subsidiaries, shall be deemed to constitute any representation or
warranty by any Agent-Related Person to any Bank. Each Bank represents to the
Agent that it has, independently and without reliance upon any Agent-Related
Person and based on such documents and information as it has deemed appropriate,
made its own appraisal of and investigation into the business, prospects,
operations, property, financial and other condition and creditworthiness of each
Loan Party and its Subsidiaries, and all applicable bank regulatory laws
relating to the transactions contemplated hereby, and made its own decision to
enter into this Agreement and to extend credit to the Borrower hereunder. Each
Bank also represents that it will, independently and without reliance upon any
Agent-Related Person and based on such documents and information as it shall
deem appropriate at the time, continue to make its own credit analysis,
appraisals and decisions in taking or not taking action under this Agreement and
the other Loan Documents, and to make such investigations as it deems necessary
to inform itself as to the business, prospects, operations, property, financial
and other condition and creditworthiness of the Borrower. Unless otherwise
provided in this Agreement, the Agent will, upon receipt of same, forward to all
of the Banks copies of all financial statements, notices, reports and other
documents required to be furnished to the Agent hereunder by any Loan Party
which are not by the terms hereof required to be distributed by such Loan Party
directly to the Banks.  Except for such financial statements, notices, reports
and other documents expressly herein required to be furnished to the Banks by
the Agent, the Agent shall not have any duty or responsibility to provide any
Bank with any credit or other information concerning the business, prospects,
operations, property, financial and other condition or creditworthiness of the
Borrower or either Guarantor or any Subsidiary which may come into the
possession of any of the Agent-Related Persons.

10.7      Indemnification of Agent.  Whether or not the transactions
          ------------------------                                  
contemplated hereby are consummated, the Banks shall indemnify upon demand the
Agent-Related Persons (to the extent not reimbursed by or on behalf of the
Borrower or the Guarantors and without limiting the obligation of the Borrower
or the Guarantors to do so), in accordance with the Banks' Pro Rata Shares, from
and against any and all Indemnified Liabilities; provided, however, that no Bank
                                                 --------  -------              
shall be liable for the payment to the Agent-Related Persons of any portion of
such Indemnified Liabilities to the extent they are found by a final decision of
a court of competent jurisdiction to have resulted from such Person's gross
negligence or willful misconduct. Without limitation of the foregoing, each Bank
shall reimburse the Agent upon demand for its ratable share of any costs or out-
of-pocket expenses (including Attorney Costs) incurred by the Agent in
connection with the preparation, execution, delivery, administration,
modification, amendment or enforcement (whether through negotiations, legal
proceedings or otherwise) of, or legal advice in respect of rights or
responsibilities under, this Agreement, any other Loan Document, or any document
contemplated by or referred to herein, to the extent that the Agent is not
reimbursed for such expenses by or on behalf of the Borrower or the Guarantors.
The undertaking in this Section shall survive the termination of the
Commitments, the payment of all other Obligations hereunder and the resignation
or replacement of the Agent.

10.8      Agent in Individual Capacity.  Bank of Montreal and its Affiliates may
          ----------------------------                                          
make loans to, accept deposits from, acquire equity interests in and generally
engage in any kind of banking, trust, financial advisory, underwriting or other
business with each Loan Party and its Subsidiaries and Affiliates as though Bank
of Montreal were not the Agent hereunder and without notice to or consent of the
Banks. The Banks acknowledge that, pursuant to such activities, Bank of Montreal
or its Affiliates may receive information regarding each Loan Party or its
Subsidiaries or Affiliates (including information that may be subject to
confidentiality obligations in favor of such Loan Party or such Subsidiary or
Affiliate) and acknowledge that the Agent shall be under no obligation to
provide such information to them. With respect to its Loans, Bank of Montreal
shall have the same rights and powers under this Agreement as any other Bank and
may exercise the same as though it were not the Agent.

10.9      Successor Agent.  The Agent may, and at the request of the Majority
          ---------------                                                    
Banks shall, resign as Agent upon 30 days' notice to the Banks. If the Agent
resigns under this Agreement, the Majority Banks, after consulting with and
giving due regard to the suggestions of JM, shall appoint from among the Banks a
successor agent for the Banks which successor agent shall be approved by the
Borrower's Designee (such approval not to be unreasonably withheld). If no
successor agent is appointed prior to the effective date of the resignation of
the Agent, the Agent may appoint, after consulting with the Banks and the
Borrower's Designee, a successor agent from among the Banks. Upon the acceptance
of its appointment as successor agent hereunder, such successor agent shall
succeed to all the rights, powers and duties of the retiring Agent and the term
"Agent" shall mean such successor agent and the retiring Agent's appointment,
powers and duties as Agent shall be terminated. After any retiring Agent's
resignation hereunder as Agent, the provisions of this Article X and Sections
11.4 and 11.5 shall enure to its benefit as to any actions taken or omitted to
be taken by it while it was Agent under this Agreement. If no

                                      64
<PAGE>
 
successor agent has accepted appointment as Agent by the date which is 30 days
following a retiring Agent's notice of resignation, the retiring Agent's
resignation shall nevertheless thereupon become effective and the Banks shall
perform all of the duties of the Agent hereunder until such time, if any, as the
Majority Banks appoint a successor agent as provided for above.

          such party in a written notice to the Borrower's Designee and the
          Agent.

     (b)  All such notices, requests and communications shall, when transmitted
          by overnight delivery, or faxed, be effective when delivered for
          overnight (next-day) delivery, or transmitted in legible form by
          facsimile machine, respectively, or if mailed, upon the third Business
          Day after the date deposited with Canada Post, or if delivered, upon
          delivery; except that notices pursuant to Article II, III or X to the

     (c)  Any agreement of the Agent and the Banks herein to receive certain

          to rely on the authority of any Person purporting to be a Person
          authorized by the Borrower to give such notice and the Agent and the
          Banks shall not have any liability to the Borrower or other Person on
          account of any action taken or not taken by the Agent or the Banks in
          reliance upon such telephonic or facsimile notice. The obligation of
          the Borrower to repay the Loans shall not be affected in any way or to
          any extent by 

                                      66

          any failure by the Agent and the Banks to receive written confirmation
          of any telephonic notice or the receipt by the Agent and the Banks of
          a confirmation which is at variance with the terms understood by the
          Agent and the Banks to be contained in the telephonic or facsimile
          notice.

11.3      No Waiver, Cumulative Remedies.  No failure to exercise and no delay
          ------------------------------                                      
in exercising, on the part of the Agent or any Bank, any right, remedy, power or
privilege hereunder, shall operate as a waiver thereof; nor shall any single or
partial exercise of any right, remedy, power or privilege hereunder preclude any
other or further exercise thereof or the exercise of any other right, remedy,
power or privilege. The rights provided for in this Agreement and the other Loan
Documents are cumulative and are not exclusive of any other rights, powers,
privileges or remedies provided by law or in equity, or under any other
instrument, document or agreement now existing or hereafter arising.

11.4      Costs and Expenses.  The Borrower shall:
          ------------------                      

     (a)  whether or not the transactions contemplated hereby are consummated,
          pay or reimburse the Agent within 30 days after demand (subject to
          subsection 5.1(f)) for all reasonable costs and expenses incurred by
          the Agent in connection with (i) the development, preparation,
          delivery and execution of, and any amendment, supplement, waiver or
          modification to (in each case, whether or not consummated), this
          Agreement, any Loan Document and any other documents prepared in
          connection herewith or therewith, and (ii) the consummation of the
          transactions contemplated hereby and thereby; and

     (b)  pay or reimburse the Agent and each Bank within five Business Days
          after demand (subject to subsection 5.1(f)) for all costs and expenses
          (including Attorney Costs) incurred by them in connection with the
          enforcement, attempted enforcement, or preservation of any rights or
          remedies under this Agreement or any other Loan Document during the
          existence of an Event of Default or after acceleration of the Loans
          (including in connection with any "workout" or restructuring regarding
          the Loans, and including in any Insolvency Proceeding or appellate
          proceeding).

11.5      Indemnification.  Whether or not the transactions contemplated hereby
          ---------------                                                      
are consummated, each Loan Party shall indemnify, defend and hold the Agent, the
Agent-Related Persons, and each Bank and each of its respective officers,
directors, employees, counsel, agents and attorneys-in-fact (each an
                                                                    
"Indemnified Person") harmless from and against any and all liabilities, claims,
- -------------------                                                             
obligations, losses, damages, penalties, actions, judgments, suits, costs,
charges, expenses and disbursements (including reasonable Attorney Costs) of any
kind or nature whatsoever which may at any time (including at any time following
repayment of the Loans and the termination, resignation or replacement of the
Agent or replacement of any Bank) be imposed on, incurred by or asserted against
any such Person in connection with any investigation, litigation or proceeding
(including any Insolvency Proceeding or appellate proceeding) in any way
relating to or arising out of this Agreement or any document contemplated by or
referred to herein, or the transactions contemplated hereby or the use of the
Proceeds of any Loans, or any 

                                      67
<PAGE>
 
action taken or omitted by any such Person under or in connection with any of
the foregoing, whether or not any Indemnified Person is a party thereto (all the
foregoing, collectively, the "Indemnified Liabilities"); provided that any Loan
Party shall have no obligation hereunder to any Indemnified Person with respect
to Indemnified Liabilities to the extent they are found by a final decision of a
court of competent jurisdiction to have resulted solely from the gross
negligence or willful misconduct of such Indemnified Person. The agreements in
this Section and in Section 11.4 shall survive the termination of the
Commitments and the payment of all other Obligations.

11.6      Payments Set Aside.  To the extent that any Loan Party makes a payment
          ------------------                                                    
to the Agent or the Banks, or the Agent or the Banks exercise their right of
set-off, and such payment or the proceeds of such set-off or any part thereof
are subsequently invalidated, declared to be fraudulent or preferential, set
aside or required (including pursuant to any settlement entered into by the
Agent or such Bank in its discretion) to be repaid to a trustee, receiver or any
other party, in connection with any Insolvency Proceeding or otherwise, then (a)
to the extent of such recovery the obligation or part thereof originally
intended to be satisfied shall be revived and continued in full force and effect
as if such payment had not been made or such set-off had not occurred, and (b)
each Bank severally agrees to pay to the Agent upon demand its pro rata share of
any amount so recovered from or repaid by the Agent.

11.7   Successors and Assigns.  The provisions of this Agreement shall be
       ----------------------                                            
binding upon and enure to the benefit of the parties hereto and their respective
successors and assigns, except that no Loan Party may assign or transfer any of
its rights or obligations under this Agreement without the prior written consent
of the Agent and each Bank.

11.8      Assignments, Participations, Etc.
          ---------------------------------

     (a)  Any Bank may, with the written consent of the Borrower's Designee and
          the Agent, (which in each case shall not be unreasonably withheld), at
          any time assign and delegate to one or more Eligible Assignees (each
          an "Assignee") all, or any ratable part of all, of the Loans, the
              --------

          Borrower's Designee or the Agent shall be required in connection with
          any assignment and delegation by a Bank to an Eligible Assignee that
          is another Bank or an Affiliate of such Bank; and (ii) except in
          connection with an assignment of all of a Bank's rights and
          obligations with respect to its Commitment and Loans any such
          assignment to an Eligible Assignee that is not a Bank hereunder shall
          be equal to or greater than $1,000,000 (Cdn.) or the U.S. Dollar
          Equivalent Amount thereof; and provided further, however, that the

          Borrower's Designee and the Agent may continue to deal solely and
          directly with such Bank in connection with the interest so assigned to
          an Assignee until (A) such Bank and its Assignee shall have delivered
          to the Borrower's Designee and the Agent an Assignment and Acceptance
          Agreement substantially in the form of Exhibit G (an "Assignment and
                                                 ---------      --------------
          Acceptance"), together with any Note or Notes - subject to such
          ----------                                                     
          assignment; (B) a written notice of such assignment, together with
          payment instructions, addresses and related information with respect
          to the Assignee, in substantially 

                                      68

          the form of the Notice of Assignment and Acceptance attached as
          Schedule 1 to the Assignment and Acceptance, shall have been given to
          the Borrower's Designee and the Agent by such Bank and the Assignee;
          and (C) the assignor Bank or Assignee shall have paid to the Agent a
          processing fee in the amount of $3,500 (Cdn.).

     (b)  From and after the date that the Agent notifies the assignor Bank that
          the Agent has received (and, if required, provided its consent with
          respect to and, if necessary, received the consent of the Borrower's
          Designee with respect to) an executed Assignment and Acceptance and
          payment of the above-referenced processing fee, (i) the Assignee
          thereunder shall be a party hereto and, to the extent that rights and
          obligations hereunder have been assigned to it pursuant to such
          Assignment and Acceptance, shall have the rights and obligations of a
          Bank under the Loan Documents, (ii) this Agreement shall be deemed to
          be amended to the extent, but only to the extent, necessary to reflect
          the addition of the Assignee and the resulting adjustment of the
          Commitments arising therefrom, and (iii) the assignor Bank shall, to
          the extent that rights and obligations hereunder and under the other
          Loan Documents have been assigned by it pursuant to such Assignment
          and Acceptance, relinquish its rights and be released from its
          obligations under the Loan Documents; provided, however that the
                                                --------  -------         
          assignor Bank shall not relinquish its rights under Article IV or
          under Sections 11.4 and 11.5 to the extent such rights relate to the
          time prior to the effective date of the Assignment and Acceptance. The
          Commitment allocated to each Assignee shall reduce the Commitment of
          the assigning Bank pro tanto.
                             --------- 

     (c)  Within five Business Days after its receipt of notice by the Agent
          that it has received (and, if necessary, consented to) an executed
          Assignment and Acceptance and payment of the processing fee (and
          provided that the Borrower's Designee consents to such assignment in
          accordance with subsection 11.8(a)), the Borrower's Designee shall
          execute and deliver to the Agent any new Notes requested by such
          Assignee evidencing such Assignee's assigned Loans and Commitment and,
          if the assignor Bank has retained a portion of its Loans and its
          Commitment, replacement Notes as requested by the assignor Bank
          evidencing the Loans and Commitment retained by the assignor Bank
          (such Notes to be in exchange for, but not in payment of, the Notes
          held by such Bank, if any).

     (d)  Any Bank may at any time sell to one or more commercial banks or other
          Persons not Affiliates of the Borrower (a "Participant") participating
                                                     -----------                
          interests in any Loans, the Commitment of that Bank and the other
          interests of that Bank (the "originating Bank") hereunder and under
          the other Loan Documents; provided, however, that (i) the originating
                                    --------  -------                          
          Bank's obligations under this Agreement shall remain unchanged, (ii)
          the originating Bank shall remain solely responsible for the
          performance of such obligations, (iii) the Borrower, the Borrower's
          Designee and the Agent shall continue to deal solely and directly with
          the originating Bank in connection with the originating Bank's rights
          and obligations under this Agreement and the other Loan Documents, and
          (iv) no Bank shall transfer or

          grant any participating interest under which the Participant has
          rights to approve any amendment to, or any consent or waiver with
          respect to, this Agreement or any other Loan Document, except to the
          extent such amendment, consent or waiver would require unanimous
          consent of the Banks as described in the first proviso to Section
          11.1. In the case of any such participation, the Participant shall be
          entitled to the benefit of Sections 4.1 (but only if and for so long
          as it is an Eligible Assignee), 4.3 and 11.5 as though it were also a
          Bank hereunder, and if amounts outstanding under this Agreement are
          due and unpaid, or shall have been declared or shall have become due
          and payable upon the occurrence of an Event of Default, each
          Participant shall be deemed to have the right of set-off in respect of
          its participating interest in amounts owing under this Agreement to
          the same extent as if the amount of its participating interest were
          owing directly to it as a Bank under this Agreement.

     (e)  Notwithstanding any other provision in this Agreement, any Bank may at
          any time create a security interest in, or pledge, all or any portion
          of its rights under and interest in this Agreement and any Note held
          by it in favour of any Federal Reserve Bank in accordance with
          Regulation A of the FRB or U.S. Treasury Regulation 31 CFR 203.14,
          and such Federal Reserve Bank may enforce such pledge or security
          interest in any manner permitted under applicable law.

11.9      Confidentiality.  Each Bank agrees to take and to cause its Affiliates
          ---------------                                                       
to take normal and reasonable precautions and exercise due care to maintain the
confidentiality of all information provided to it by any of the Loan Parties or
any Subsidiary, or by the Agent on behalf of such Loan Party or such Subsidiary,

Affiliates shall use any such information other than in connection with or in
enforcement of this Agreement and the other Loan Documents or in connection with
other business now or hereafter existing or contemplated with any of the Loan
Parties or any Subsidiary; except to the extent such information (i) was or
becomes generally available to the public other than as a result of disclosure
by such Bank, or (ii) was or becomes available on a non-confidential basis from
a source other than any of the Loan Parties or any Subsidiary, provided that
                                                               --------     
such source is not bound by a confidentiality agreement with any of the Loan
Parties or any of their respective Subsidiaries known to such Bank; provided,

however, that any Bank may disclose such information (A) at the request or

auditors, legal counsel and other professional advisors; (G) to any Participant
or Assignee, actual or potential, provided that such Person agrees in writing to

hereunder, (H) as to any Bank or its Affiliate, as expressly permitted under the
terms of any other document or agreement regarding confidentiality to which the

by law, if an Event of Default exists or the Loans have been accelerated, each
Bank is authorized at any time and from time to time, without prior notice to
the Borrower or the Borrower's Designee, any such notice being waived by the
Borrower and the other Loan Parties to the fullest extent permitted by law, to
set off and apply any and all deposits (general or special, time or demand,
provisional or final) at any time held by, and other indebtedness at any time
owing by, such Bank to or for the credit or the account of the Borrower against
any and all Obligations owing to such Bank, now or hereafter existing,
irrespective of whether or not the Agent or such Bank shall have made demand
under this Agreement or any Loan Document and although such Obligations may be
contingent or unmatured. Each Bank agrees promptly to notify the Borrower's
Designee and the Agent after any such set-off and application made by such Bank;
provided, however, that the failure to give such notice shall not affect the
validity of such set-off and application.

original, and all of said counterparts taken together shall be deemed to
constitute but one and the same instrument.

11.13     Severability.  The illegality or unenforceability of any provision of

*    1. The Leverage Ratio used to compute the Applicable Fee Amount, the
     Applicable Margin with respect to any LIBOR Loans and the applicable BA
     Stamping Fee for any Bankers' Acceptance shall be the Leverage Ratio set
     forth in Schedule 1 attached to the Compliance Certificate most recently
     delivered by the Borrower's Designee pursuant to Section 7.2(a) of the
     Credit Agreement; changes in the Applicable Fee Amount, Applicable Margin
     with respect to the LIBOR Loans and applicable BA Stamping Fee resulting
     from a change in the Leverage Ratio shall become effective upon delivery by
     the Borrower's Designee to the Agent of a new Compliance Certificate
     pursuant to Section 7.2(a). If the Borrower's Designee shall fail to
     deliver a Compliance Certificate within the number of days after the end of
     any fiscal quarter or fiscal year as required pursuant to Section 7.2(a)
     (without giving effect to any grace period), the Applicable Fee Amount,
     Applicable Margin with respect to LIBOR Loans and applicable BA Stamping
     Fee from the first day after the date on which such Compliance Certificate
     was required to be delivered to the Agent to the Day the Borrower's
     Designee delivers to the Agent a Compliance Certificate shall conclusively
     equal the highest Applicable Fee Amount, Applicable Margin with respect to
     LIBOR Loans and applicable BA Stamping Fee set forth above.

     2. Notwithstanding the foregoing, the Applicable Fee Amount, Applicable
     Margin with respect to LIBOR Loans and applicable BA Stamping Fee for every
     day during the six-month period beginning on the Closing Date shall be no
     lower than Level III plus 1/10 of 1% per annum.

     3. If on any day and for each day after the initial six-month period
     referred to in note 2 above the Effective Amount of all Revolving Loans
     plus the Effective Amount of all Swingline Loans plus the Effective Amount
     of all L/C Obligations (as such terms are defined in the U.S. Credit
     Agreement) exceeds 50% of the Aggregate Commitment (as also defined
     therein) then in effect under the U.S. Credit Agreement, (a) the Applicable
     Margin with respect to LIBOR Loans shall be increased by 1/10 of 1% per
     annum for each such day and (b) a supplemental BA Stamping Fee shall be
     payable for each such day in respect of each Bankers' Acceptance
     outstanding on each such day, payable on the date such Bankers' Acceptance
     matures, in an amount determined by (i) multiplying the undiscounted face
     amount of such Bankers' Acceptance by 1/10 of 1% and (ii) dividing the
     result by 365 or 366, as the case may be.
