                  NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                  ------------------------------------------
                                        

1.  Financial Statement Presentation
    --------------------------------

Conectiv's consolidated condensed interim financial statements contained herein
include the accounts of Conectiv and its majority-owned subsidiaries and reflect
all adjustments necessary in the opinion of management for a fair presentation
of interim results.  In accordance with regulations of the Securities and
Exchange Commission, disclosures which would substantially duplicate the
disclosures in Conectiv's 1998 Report on Form 10-K have been omitted.
Accordingly, Conectiv's consolidated condensed interim financial statements
contained herein should be read in conjunction with Conectiv's 1998 Report on
Form 10-K and Part II of this Report on Form 10-Q for additional relevant
information.

On March 1, 1998, Conectiv became a holding company that owns Delmarva Power &
Light Company (DPL), Atlantic City Electric Company (ACE) and other subsidiaries
(the Merger).  Under the purchase method of accounting, with DPL as the acquirer
of Atlantic Energy, Inc. (Atlantic) and its subsidiaries, the Consolidated
Statement of Income for the three months ended March 31, 1998 includes one month
of results of operations for ACE and nonutility subsidiaries formerly owned by
Atlantic.  For additional information about the Merger, see Note 4 to the
Consolidated Financial Statements included in Conectiv's 1998 Report on Form 10-
K.  See Note 4 to the Consolidated Financial Statements of this report for
comparative pro forma information.

2.  Investment Income
    -----------------

ATE Investment, Inc. (ATE), a wholly-owned Conectiv subsidiary, holds a 94%
limited partner interest in Enertech Capital Partners, L.P. (Enertech).
Enertech is a venture capital fund which invests in energy-related technology
and service companies.  Enertech records its investments at fair value and
includes gains and losses on changes in the fair value of its investments in
income in accordance with industry practice.  Conectiv accounts for ATE's
investment in Enertech on the equity method of accounting.  Conectiv's equity in
pre-tax earnings of Enertech for the first quarter of 1999 was $16.0 million
($9.4 million after-income taxes or $0.09 per common share).  The pre-tax
earnings of $16.0 million are reported as "Other income" within the Consolidated
Statement of Income for the first quarter of 1999.  Conectiv's equity in
earnings of Enertech was not significant in 1998.  Due to the nature of
Enertech's investments, which include internet service companies, its earnings
may be volatile from period to period.

3.  Employee Separation and Other Merger-Related Costs
    --------------------------------------------------

In the first quarter of 1998, enhanced retirement offers and other employee
separation programs were utilized to reduce the workforces of DPL, ACE, and
other Conectiv subsidiaries.  The costs for separated DPL employees and other
Merger-related costs expensed in the first quarter of 1998 were $40.6 million
before taxes, reducing net income and earnings per common share by  $24.6
million and $0.33, respectively.  The $40.6 million charge to expense was net of
a $32.5 million gain from curtailments and settlements of pension and other
postretirement benefits, based on actual settlements through March 31, 1998.

Employee separation, relocation, and other Merger-related costs for Atlantic and
its former subsidiaries were capitalized as costs of the Merger.

4.  Pro Forma Information (unaudited)
    ---------------------------------

Actual unadjusted operating results for the first quarter of 1999 and pro forma
unaudited financial information for the first quarter of 1998, giving effect to
the Merger as if it had occurred on January 1, 1998, are presented below.  The
first quarter 1998 pro forma information has not been adjusted to exclude the
charge to earnings for employee separation and other Merger-related costs
incurred by DPL which reduced operating income, net income, earnings applicable
to common stock and earnings per average Conectiv common share by $40.6 million,
$24.6 million, $24.6 million, and $0.33, respectively.  The pro forma
information presented below is not necessarily indicative of the results that
would have occurred, or that will occur in the future.

5.  Rate Matters
    ------------

The following information updates the disclosures previously made in Note 6,
Rate Matters, to Conectiv's Consolidated 1998 Financial Statements included in
Conectiv's 1998 Report on Form 10-K.

Asset Impairments and Charges to Earnings

Management has made a preliminary estimate of the amount of stranded costs not
expected to be recovered through regulated electricity delivery rates after the
restructuring of the electric utility industry in the states in which ACE and
DPL operate.  The New Jersey, Delaware, and Maryland public utility regulatory
commissions are expected to issue restructuring orders for ACE and DPL which
specify the amount and timing of stranded cost recovery by the following
expected dates: New Jersey--by June 30, 1999; Delaware--by August 31, 1999;
Maryland--by October 1, 1999.  After the orders are received, the financial
impact of the restructurings, including charges to earnings, will be finalized
and recorded.  When the restructuring orders become effective, the electricity
supply businesses of ACE and DPL will no longer be subject to the requirements
of Statement of Financial Accounting Standards (SFAS) No. 71, "Accounting for
the Effects of Certain Types of Regulation."  The discussion below describes the
primary immediate expected effect on the results of operations of discontinuing
the application of SFAS No. 71 to these electricity supply businesses.

                                      -6-
<PAGE>
 
To estimate the impairment of electric generating plants of DPL and ACE in
accordance with generally accepted accounting principles (GAAP), the book value
of each generating plant is first compared to the estimated future net operating
cash flows of each generating plant. Any electric generating plant with
undiscounted future net cash flows less than book value is considered impaired,
and the plant's net future cash flows are discounted. The amount by which the
book value of the impaired electric generating plants exceeds their discounted
cash flows (or other estimate of fair value) is the estimated impairment amount.

DPL has purchased power contracts expected to be uneconomic when customer choice
begins, and the stranded cost amount is estimated to be the net present value of
the contracts' costs less the forecasted revenues from sales of the purchased
power.  ACE's purchased power contracts with independent power producers are not
expected to result in stranded costs because management expects the New Jersey
Board of Public Utilities' (NJBPU) restructuring order will provide for recovery
of costs incurred under these contracts.

The total amount that could be charged to earnings, on a consolidated basis,
includes (a) the impairment amount for the electric generating plants of DPL and
ACE, (b) the stranded cost amount for DPL's purchased power contracts, and (c)
regulatory assets of DPL and ACE related to their electric generation
businesses. The charge to earnings is reduced by the estimated cost recovery
through regulated electricity delivery rates. Based on this methodology, (giving
effect to estimated cost recoveries) management currently estimates future
charges to earnings, after taxes, as a result of electric utility industry
restructuring could be as follows:

<TABLE> 
<S>                         <C> 
DPL                          $300 million to $425 million
ACE                          $ 50 million to $ 75 million
                             ----------------------------
Consolidated Conectiv        $350 million to $500 million
                             ============================
</TABLE> 

Expected Sales of Electric Generating Plants

Management also expects to sell some or all of the electric generating plants of
DPL and ACE. After electric generating plants that are impaired as a result of
electric utility industry restructuring are written down to fair value, any
sales of the impaired electric generating plants are not expected to result in
significant gains or losses. Some of the electric generating plants which are
not impaired may be sold at a gain. Under GAAP, the write-down of impaired
assets is not reduced by expected future gains on sales of assets which are not
impaired by electric utility industry restructuring; the gain on the sale of an
asset is recognized when the sale occurs.

Under New Jersey electric utility restructuring legislation, any gains on sales
of ACE's electric generating plants reduce stranded cost recovery, which results
in no earnings effect when the gain is realized.  DPL's agreements with some
participants in restructuring proceedings expected to be conducted by the
Delaware Public Service Commission (DPSC) and with some of the participants in
the proceedings being conducted by the Maryland Public service commission (MPSC)
provide that electric rates will not be changed in the event DPL sells or
transfers assets. Accordingly, subject to DPSC and MPSC approval of these
agreements, the Delaware and Maryland portions of any gains, or losses, realized
on the sale of DPL electric generating plants would affect future earnings.
There can be no assurances, however, that DPL or ACE will elect or be able to
sell any such electric generating plants, or that any gains will be realized
from such sales of electric generating plants.

After the sale of electric generating plants is completed, management estimates 
that the net impact on retained earnings of asset impairments, stranded costs, 
and asset sales to be a charge of approximately $300 million to $400 million.

New Jersey Electric Utility Restructuring Legislation

As previously reported, the Electric Discount and Energy Competition Act (the
New Jersey Act) was signed into law by the Governor of New Jersey on February 9,
1999.  The New Jersey Act requires electric utilities to reduce their rates by
at least 5% at the start of retail choice (scheduled for August 1, 1999) and by
a total of 10% within 36 months of the start of choice.  Assuming that the rate 
reduction had been effective as of January 1, 1998, management estimates that 
the impact on revenue of ACE from the initial rate reduction of 5% would have 
been to decrease revenue during the fiscal year ended December 31, 1998 by 
approximately $38 million.

                                      -7-
<PAGE>
 
Settlement discussions in the NJBPU restructuring proceeding for ACE are 
ongoing.

Delaware Electric Utility Restructuring Legislation

As previously reported, the Delaware General Assembly passed the Electric
Utility Restructuring Act of 1999 (the Delaware Act) on March 25, 1999. On March
31, 1999, the Governor of Delaware signed the Delaware Act. Assuming that a 7.5%
rate reduction, as required by the Delaware Act, had been effective as of
January 1, 1998, management estimates that the impact on revenue of DPL would
have been to decrease revenue during the fiscal year ended December 31, 1998 by
approximately $17 million. The Delaware Act makes DPL the provider of default
service to customers who do not choose an alternative supplier for a period of 3
or 4 years for non-residential and residential customers, respectively.
Thereafter, the DPSC may conduct a bidding process to select the default
supplier(s) for such customers. The DPSC also has the authority under the
Delaware Act to order DPL to divest its generating assets, as a last resort, to
remedy any adverse effects of electricity supply market power. The DPSC also is
authorized to establish licensing standards for electricity suppliers. Unless
DPL asks the DPSC to makes these functions competitive earlier, and the DPSC so
orders, metering functions will be performed by DPL for 3 or 4 years after they
may choose their electricity suppliers, for non-residential customers and
residential customers, respectively. Among other matters, unbundled rates to be
charged by DPL during the "rate freeze" periods prescribed by the Delaware Act
have been agreed upon by a number of the participants in the restructuring
proceeding contemplated by the Delaware Act. Included within the agreement on
unbundled rates, which is subject to DPSC approval, DPL would recover $16
million (Delaware retail basis) of stranded costs, and electric rates would not
be changed in the event DPL sells or transfers generating assets.

Maryland Electric Utility Restructuring Legislation

On April 2, 1999, the Maryland General Assembly passed the Electric Utility
Industry Restructuring Act of 1999 (the Maryland Act).  On April 8, 1999, the
Governor of Maryland signed the Maryland Act.  The major elements of the
Maryland Act include the following:

(A) Phase-in of retail choice beginning in July 2000, with full choice for all
customers by July 2003;

(B) Rate reductions of 3% to 7.5% for residential customers with rates then held
constant for four years;

(C) The deregulation of generating assets sold to a non-affiliate or transferred
to an affiliate prior to January 1, 2001;

(D) Recovery of stranded costs and other costs associated with the transition to
retail choice through a method to be determined by the Maryland Public Service
Commission (MPSC);

(E) Imposition by the MPSC of an environmental surcharge on each kilowatt-hour 
distributed in Maryland;

(F) The creation of a statewide fund for low-income assistance.

On May 5, 1999, DPL filed a proposed settlement with the MPSC in DPL's pending
restructuring proceeding.  The proposed settlement is with some parties,
including the MPSC Staff and the Office of People's Counsel, but not all parties
to the proceeding.  Included in the proposed settlement are the following
provisions:  (i) effective July 1, 2000, all of DPL's Maryland-retail customers
will be eligible to select an alternative electricity supplier; (ii) for a
period of at least 3 years thereafter, DPL will remain the supplier of "standard
offer service" for customers who do not select an alternative electricity
supplier; (iii) agreed-upon unbundled rates (including nuclear decommissioning
costs and funding for low income energy assistance programs at an estimated
level of between $2 and $3 million per year); (iv) the deregulation of DPL's
generating facilities, such that electric rates would not be changed in the
event DPL sells or transfers generating assets (v) authorization to transfer DPL
generating assets to one or more affiliates at net book value; (vi) the recovery
of an estimated $8 million (Maryland retail basis) in stranded costs from non-

                                      -8-
<PAGE>
 
residential customers; (vii) a 7.5% reduction in residential rates effective
July 1, 2000 (representing a revenue reduction of approximately $12.5 million,
assuming fiscal year 1998 sales and revenue levels; and (viii) effective July 1,
2000, "rate freezes" for 4 years for residential customers and 3 years for non-
residential customers, subject to certain adjustments. In addition, under the
proposed settlement, effective July 1, 2000, DPL customers with loads in excess
of 300 kilowatts (kW) may elect to have meters installed and read by an
alternative supplier. Prior to that date, another MPSC proceeding will be
initiated to determine the level of and recovery mechanism for any DPL stranded
metering costs. Other DPL customers will be eligible for competitive metering on
April 1, 2002 as set forth in the Maryland Act.

The MPSC is expected to issue an order with respect to the proposed settlement
by October 1, 1999.

Virginia Electric Utility Industry Restructuring Legislation

As previously reported, electric utility restructuring legislation was
introduced in the Virginia General Assembly on January 21, 1999.  The Virginia
General Assembly passed the Virginia Electric Utility Restructuring Act (the
Virginia Act) on March 25, 1999. On March 29, 1999, the Governor of Virginia
signed the Virginia Act.

6.  Conectiv Class A Common Stock
    -----------------------------

Earnings applicable to Conectiv Class A common stock are equal to 30% of the net
of (1) earnings attributable to ACE's regulated electric utility business, as
the business existed on August 9, 1996, less (2) $40 million per year.  Earnings
applicable to Conectiv common stock are the consolidated earnings of Conectiv
less earnings applicable to Conectiv Class A common stock.

Summarized ACE financial information and the calculation of earnings applicable
to Conectiv Class A common stock are presented below and on the following page.
Under purchase method accounting, the Consolidated Conectiv Statement of Income
for the three months ended March 31, 1998 includes ACE's operating results for
the month of March 1998.

       were capitalized as costs of the Merger.


7.  Contingencies
    -------------

Environmental Matters
- ---------------------
Conectiv's subsidiaries are subject to regulation with respect to the
environmental effects of their operations, including air and water quality
control, solid and hazardous waste disposal, and limitations on land use by
various federal, regional, state, and local authorities.  Federal and state
statutes authorize governmental agencies to compel responsible parties to clean
up certain abandoned or uncontrolled hazardous waste sites.  Costs may be
incurred to clean up facilities found to be contaminated due to past disposal
practices.  Conectiv's current liabilities include $3.0 million as of March 31,
1999 and December 31, 1998, respectively, for potential clean-up and other costs
related to sites at which a Conectiv subsidiary is a potentially responsible
party or alleged to be a third party contributor.  Conectiv does not expect such
future costs to have a material effect on its financial position or results of
operations.

Nuclear Insurance
- -----------------
In conjunction with the  ownership interests of DPL and ACE in Peach Bottom
Atomic Power Station (Peach Bottom), Salem Nuclear Generating Station (Salem),
and Hope Creek Nuclear Generating Station (Hope Creek), DPL and ACE could be
assessed for a portion of any third-party claims associated with an incident at
any commercial nuclear power plant in the United States.  Under the provisions
of the Price Anderson Act, if third-party claims relating to such an incident
exceed $200 million (the amount of primary insurance), DPL and ACE could be
assessed up to $57.0 million on an aggregate basis for such third-party claims.
In addition, Congress could impose a revenue-raising measure on the nuclear
industry to pay such claims.

                                      -10-
<PAGE>
 
The co-owners of Peach Bottom, Salem, and Hope Creek maintain property insurance
coverage of approximately $2.8 billion for each unit for loss or damage to the
units, including coverage for decontamination expense and premature
decommissioning.  In addition, Conectiv is a member of an industry mutual
insurance company, which provides replacement power cost coverage in the event
of a major accidental outage at a nuclear power plant.  Under these coverages,
Conectiv is subject to potential retrospective loss experience assessments of up
to $9.4 million on an aggregate basis.

9.  Business Segments
    -----------------

The following information is presented in accordance with SFAS No. 131,
"Disclosures about Segments of an Enterprise and Related Information."
Conectiv's business segments under SFAS No. 131 are as follows: Generation--
produces electricity and operates power plants; Merchant--purchases and sells
bulk energy; Power Delivery--delivers electricity and gas to customers at
regulated prices over transmission and distribution systems; All Other--includes
heating, ventilation, and air conditioning (HVAC), plumbing, telephone and other
services provided to homes and businesses; thermal heating and cooling systems
for large commercial and industrial customers; and various other businesses
which are not subject to price regulation.

Billings to electric and gas customers under regulated tariffs include amounts
for services provided by the Generation, Merchant, and Power Delivery business
segments.  These revenues are allocated directly to the business segments based
on the cost of services provided.  The Merchant business segment also earns
revenues from bulk energy sales to off-system customers in markets not subject
to price regulation.

The operating results for each business segment are evaluated based on a profit
measure called "contribution to corporate," which is equal to operating revenues
and other income less operating expenses other than corporate expenses.  All
Other business segments' contribution to corporate for the three months ended
March 31, 1999 includes $16.0 million from ATE's investment in Enertech as
discussed in Note 2 to the Consolidated Financial Statements.

For the three months ended March 31, 1998, the business segment's revenues and
contribution to corporate include the January and February 1998 operating
results of the former Atlantic-owned companies and exclude Merger-related costs
charged to expense.

                 OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS
                 ------------------------------------------------
                                        
Earnings Summary
- ----------------

Conectiv's consolidated operating results for the first quarter of 1999 include
three months of operating results for ACE and the nonutility businesses formerly
owned by Atlantic, whereas consolidated operating results for the first quarter
of 1998 include one month (March 1998) of operating results for these
businesses, in accordance with the purchase method of accounting.

Reported earnings applicable to Conectiv common stock were $47.4 million, or
$0.47 per average common share (100,532,000 average common shares) for the first
quarter of 1999, compared to a loss of $4.1 million, or $0.06 per average common
share (74,684,000 average common shares) in the first quarter of 1998.  The
earnings per share dilution resulting from Conectiv common shares issued to
Atlantic stockholders on March 1, 1998 was offset by the additional two months
of net earnings contributed in the first quarter of 1999 by the former Atlantic-
owned companies.

First quarter 1999 earnings include equity in earnings of a limited partnership
investment of $0.09 per common share, and first quarter 1998 earnings reflect a
charge of $0.33 per common share for DPL employee separation costs and other
Merger-related costs.  Excluding these two items, earnings per share of Conectiv
common stock were $0.38 for the first quarter of 1999 compared to $0.27 for the
first quarter of 1998.  The $0.11 increase in earnings per common share (as
adjusted) was primarily attributed to (a) higher regulated retail electric and
gas sales, which increased mainly due to colder winter weather than last year,
and (b) lower utility operating and maintenance expenses exclusive of the two
additional months of ACE's operations, which decreased mainly due to Merger-
related reductions in the number of employees.  The operations of Conectiv's
telecommunications business, HVAC business, and competitive retail energy
business resulted in a net after-tax loss of $9.2 million ($0.09 per common
share) in the first quarter of 1999 compared to a net after-tax loss of $6.6
million ($0.09 per common share) in the first quarter of 1998.

Earnings available for Conectiv Class A common stock were $1.3 million or $0.20
per Class A common share for the first quarter of 1999 compared to $0.2 million
or $0.02 per Class A common share for the first quarter of 1998.  The increase
in Conectiv Class A common stock earnings was primarily attributed to the two
additional months of ACE's earnings.  Average shares outstanding of Conectiv
Class A common stock were 6,560,612 in the first quarter of 1999 and 1998.  For
additional information, see Note 6 to the Consolidated Financial Statements.

Electric Utility Industry Restructuring
- ---------------------------------------

Effect on Revenues

As previously reported, provisions for customer rate reductions included in
electric utility industry restructuring legislation become effective when
customer choice begins this year in New Jersey and Delaware, and next year in
Maryland.  Without reflecting other factors, the initial reduction in Conectiv's
annual electric revenues due to the restructuring legislation rate reductions
implemented in 1999 and 2000 is estimated to be up to $68 million in total.
Management expects to offset substantially all of the revenue reductions with,
among other things, a productivity improvement and cost reduction program.
There can be no assurances, however, that Conectiv will be able to achieve its
productivity improvement and cost reduction goals under the program, or that
such productivity improvements and cost reductions as are achieved, will be
sufficient to offset these revenue reductions.

                                      -13-
<PAGE>
 
Asset Impairments and Charges to Earnings

Management has made a preliminary estimate of the amount of stranded costs not
expected to be recovered through regulated electricity delivery rates after the
restructuring of the electric utility industry in the states in which ACE and
DPL operate.  The New Jersey, Delaware, and Maryland public utility regulatory
commissions are expected to issue restructuring orders for ACE and DPL which
specify the amount and timing of stranded cost recovery by the following
expected dates: New Jersey--by June 30, 1999; Delaware--by August 31, 1999;
Maryland--by October 1, 1999.  After the orders are received, the financial
impact of the restructurings, including charges to earnings, will be finalized
and recorded.  When the restructuring orders become effective, the electricity
supply businesses of ACE and DPL will no longer be subject to the requirements
of SFAS No. 71.  The discussion below describes the primary immediate expected
effect on the results of operations of discontinuing the application of SFAS No.
71 to these electricity supply businesses.

To estimate the impairment of the electric generating plants of DPL and ACE in
accordance with GAAP, the book value of each generating plant is first compared
to the estimated future net operating cash flows of each generating plant. Any
electric generating plant with undiscounted future net cash flows less than book
value is considered impaired, and the plant's net future cash flows are
discounted. The amount by which the book value of the impaired electric
generating plants exceeds their discounted cash flows (or other estimate of fair
value) is the estimated impairment amount.

DPL has purchased power contracts expected to be uneconomic when customer choice
begins, and the stranded cost amount is estimated to be the net present value of
the contracts' costs less the forecasted revenues from sales of the purchased
power.  ACE's purchased power contracts with independent power producers are not
expected to result in stranded costs because management expects the New Jersey
Board of Public Utilities' (NJBPU) restructuring order will provide for recovery
of costs incurred under these contracts.

The total amount that could be charged to earnings, on a consolidated basis,
includes (a) the impairment amount for the electric generating plants of DPL and
ACE, (b) the stranded cost amount for DPL's purchased power contracts, and (c)
regulatory assets of DPL and ACE related to their electric generation
businesses. The charge to earnings is reduced by the estimated cost recovery
through regulated electricity delivery rates. Based on this methodology, (giving
effect to estimated cost recoveries) management currently estimates future
charges to earnings, after taxes, as a result of electric utility industry
restructuring could be as follows:
 
<TABLE> 
<S>                       <C> 
DPL                        $300 million to $425 million
ACE                        $ 50 million to $ 75 million
                           ----------------------------
Consolidated Conectiv      $350 million to $500 million
                           ============================
</TABLE> 
Expected Sales of Electric Generating Plants

Management also expects to sell some or all of the electric generating plants of
DPL and ACE. After electric generating plants that are impaired as a result of
electric utility industry restructuring are written down to fair value, any
sales of the impaired electric generating plants are not expected to result in
significant gains or losses. Some of the electric generating plants which are
not impaired may be sold at a gain. Under GAAP, the write-down of impaired
assets is not reduced by expected future gains on sales of assets which are not
impaired by electric utility industry restructuring; the gain on the sale of an
asset is recognized when the sale occurs.

                                      -14-
<PAGE>
 
Under New Jersey electric utility restructuring legislation, any gains on sales
of ACE's electric generating plants reduce stranded cost recovery, which results
in no earnings effect when the gain is realized.  DPL's agreements with some
participants in restructuring proceedings expected to be conducted by the DPSC
and with some of the participants in the proceedings being conducted by the 
Maryland Public Service Commission (MPSC) provide that electric rates will not
be changed in the event DPL sells or transfers assets. Accordingly, subject to
DPSC and MPSC approval of these agreements, the Delaware and Maryland portions
of any gains, or losses, realized on the sale of DPL electric generating plants
would affect future earnings. There can be no assurances, however, that DPL or
ACE will elect or be able to sell any such electric generating plants, or that
any gains will be realized from such sales of electric generating plants.

After the sale of electric generating plants is completed, management estimates
that the net impact on retained earnings of asset impairment, stranded costs, 
and asset sales to be a charge of approximately $300 million to $400 million.

Intent to Renegotiate Purchased Power Contracts

ACE has four NJBPU-approved long-term power purchase contracts with independent 
power producers. ACE continues to negotiate buyouts and buydowns of these 
contracts, which would be subjec to NJBPU and other approvals, including NJBPU 
authorization to recover any contract buyout and buydown costs through the 
issuance of transition bonds, as permitted by the New Jersey Act. The financial 
commitments associated with such buyouts and buydowns could be substantial. 
Management cannot currently predict the outcome of contract buyout and buydown 
negotiations or the costs associated with such efforts. There can be no 
assurances, moreover, that the NJBPU will approve the issance of transition 
bonds for such costs or that ACE will be able to issue and sell any such bonds.

On May 7, 1999, ACE and an independent power producer, with which ACE has a 
long-term power purchase contract, signed a letter of intent ("LOI") relating to
a transaction which could ultimately result in the termination of such existing 
contract. The LOI calls for the negotiation of a definitive agreement and the 
establishment of necessary arrangements associated with the termination. Upon 
receipt of corporate and regulatory approvals (including NJBPU approval), the 
agreement would require, among other things, a substantial payment to the 
independent power producer (estimated to be in excess of $100 million). 
Management cannot predict whether the LOI will result in the negotiation of a 
definitive agreement or if such an agreement would receive the necessary 
approvals.

New Jersey Electric Utility Industry Restructuring Legislation

As previously reported, the Electric Discount and Energy Competition Act (the
New Jersey Act) was signed into law by the Governor of New Jersey on February 9,
1999. The New Jersey Act requires electric utilities to reduce their rates by at
least 5% at the start of retail choice (scheduled for August 1, 1999) and by a
total of 10% within 36 months of the start of choice. Assuming that the rate
reduction had been effective as of January 1, 1998, management estimates that
the impact on revenue of ACE from the initial rate reduction of 5% would have
been to decrease revenue during the fiscal year ended December 31, 1998 by
approximately $38 million. Settlement discussions in the NJBPU restructuring 
proceeding for ACE are ongoing.

Delaware Electric Utility Industry Restructuring Legislation

As previously reported, the Delaware General Assembly passed the Electric
Utility Restructuring Act of 1999 (the Delaware Act) on March 25, 1999. On 
March 31, 1999, the Governor of Delaware signed the Delaware Act. Assuming that
a 7.5% rate reduction, as required by the Delaware Act, had been effective as of
January 1, 1998, management estimates that the impact on revenue of DPL would
have been to decrease revenue during the fiscal year ended December 31, 1998 by
approximtely $17 million. The Delaware Act makes DPL the provider of default 
service to customers who do not choose an alternative supplier for a period of 3
or 4 years for non-residential and residential customers, respectively. 
Thereafter, the DPSC may conduct a bidding process to select the default 
supplier(s) for such customers. The DPSC also has the authority under the 
Delaware Act to order DPL to divest its generating assets, as a last resort, to 
remedy any adverse effects of electricity supply market power. The DPSC also is 
authorized to establish licensing standards for electricity suppliers. Unless 
DPL asks the DPSC to makes these functions competitive earlier, and the DPSC so 
orders, metering functions will be performed by DPL for 3 or 4 years after they 
may choose their electricity suppliers, 

                                      -15-
<PAGE>
 
for non-residential customers and residential customers, respectively. Among
other matters, unbundled rates to be charged by DPL during the "rate freeze"
periods prescribed by the Delaware Act have been agreed upon by a number of the
participants in the restructuring proceeding contemplated by the Delaware Act.
Included within the agreement on unbundled rates which is subject to DPSC
approval, DPL would recover $16 million (Delaware retail basis) of stranded
costs, and electric rates would not be changed in the event DPL sells or
transfers generating assets.

Maryland Electric Utility Industry Restructuring Legislation

On April 2, 1999, the Maryland General Assembly passed legislation to
restructure the electric utility industry (the Maryland Act).  On April 8, 1999,
the Governor of Maryland signed the Maryland Act.  The major elements of the
Maryland Act include the following:

(A) Phase-in of retail choice beginning in July 2000, with full choice for all
customers by July 2003;

(B) Rate reductions of 3% to 7.5% for residential customers, with rates then 
held constant for four years;

(C) The deregulation of generating assets sold to a non-affiliate or transferred
to an affiliate prior to January 1, 2001;

(D) Recovery of stranded costs and other costs associated with the transition to
retail choice through a method to be determined by the MPSC;

(E) Imposition by the MPSC of an environmental surcharge on each kilowatt-hour 
distributed in Maryland;

(F) The creation of a statewide fund for low-income assistance.

On May 5, 1999, DPL filed a proposed settlement with the MPSC in DPL's pending
restructuring proceeding.  The proposed settlement is with some parties,
including the MPSC Staff and the Office of People's Counsel, but not all parties
to the proceeding.  Included in the proposed settlement are the following
provisions:  (i) effective July 1, 2000, all of DPL's Maryland-retail customers
will be eligible to select an alternative electricity supplier; (ii) for a
period of at least 3 years thereafter, DPL will remain the supplier of "standard
offer service" for customers who do not select an alternative electricity
supplier; (iii) agreed-upon unbundled rates (including nuclear decommissioning
costs and funding for low income energy assistance programs at an estimated
level of between $2 and $3 million per year); (iv) the deregulation of DPL's
generating facilities, such that electric rates would not be changed in the
event DPL sells or transfers generating assets (v) authorization to transfer DPL
generating assets to one or more affiliates at net book value; (vi) the recovery
of an estimated $8 million (Maryland retail basis) in stranded costs from non-
residential customers; (vii) a 7.5% reduction in residential rates effective
July 1, 2000 (representing a revenue reduction of approximately $12.5 million,
assuming fiscal year 1998 sales and revenue levels; and (viii) effective July 1,
2000, "rate freezes" for 4 years for residential customers and 3 years for non-
residential customers, subject to certain adjustments. In addition, under the
proposed settlement, effective July 1, 2000, DPL customers with loads in excess
of 300 kilowatts (kW) may elect to have meters installed and read by an
alternative supplier. Prior to that date, another MPSC proceeding will be
initiated to determine the level of and recovery mechanism for any DPL stranded
metering costs. Other DPL customers will be eligible for competitive metering on
April 1, 2002 as set forth in the Maryland Act.

The MPSC is expected to issue an order with respect to the proposed settlement
by October 1, 1999.

Virginia Electric Utility Industry Restructuring Legislation

As previously reported, electric utility restructuring legislation was
introduced in the Virginia General Assembly on January 21, 1999.  The Virginia
General Assembly passed the Virginia Electric Utility Restructuring Act (the
Virginia Act) on March 25, 1999.  On March 29, 1999, the Governor of Virginia
signed the Virginia Act.  In 1998, revenues from DPL's Virginia customers
comprised less than 2% of consolidated Conectiv electric revenues earned from
regulated electricity sales.

Notes to Restructuring Legislation Summary Chart

(1) Represents the dates on which electric customers can choose their
    electricity supplier according to the schedules established by the
    restructuring legislation, which are subject to change. (kW represents
    kilowatt.)

(2) Represents the percentage reductions in customers' electric rates required
    by the restructuring legislation. The proposed settlement filed in Maryland
    provides for a 7.5% residential rate reduction.

(3) Represents the estimated decrease in annual electric revenues which will
    occur when customer rates are reduced by the initial percentages required by
    the restructuring legislation.

(4) Represents the "rate freeze" period, which begins when customer choice
    becomes effective and after restructuring rate reductions are effective,
    during which customer rates remain unchanged.

(5) (a) The New Jersey Act authorizes the NJBPU to permit electric utilities to
    recover the full amount of their stranded costs through a non-bypassable
    market transition charge, as long as mandated rate reductions are achieved.
    The NJBPU is expected to issue a restructuring order for ACE by June 30,
    1999. There can be no assurances, however, that the NJBPU will permit ACE to
    recover the full amount of such stranded costs.

    (b) DPL's settlement with some participants in restructuring proceedings
    expected to be conducted by the DPSC provides for DPL's recovery of $16
    million (on a Delaware retail basis) of stranded costs from non-residential
    customers. There can be no assurances, however, that the DPSC will permit
    DPL to recover such standed costs.

    (c) Recovery of stranded costs and other costs associated with the
    transition to retail choice is permitted through a method to be determined
    by the MPSC. The proposed settlement provides for the recovery of an
    estimated $8 million (Maryland retail basis) in stranded costs from non-
    residential customers. There can be no assurances, however, that the MPSC
    will permit DPL to recover such stranded costs.

(6) The sale of electric generating plants is not required by electric utility
    restructuring legislation in New Jersey, Delaware, or Maryland.  New
    Jersey's regulatory treatment of a utility-initiated divestiture of
    generation assets is indicated in the chart.

(7) "Securitization" refers to the issuance of debt securitized by the cash
    flows collected from customers for stranded cost recovery.  The New Jersey
    Act and the Maryland Act provide for securitization; the Delaware Act does
    not.

Delaware Retail Gas Pilot Program

On April 27, 1999, the DPSC approved DPL's plan for a Natural Gas Choice
Program.  Beginning on July 15, 1999, 15,000 current DPL residential natural gas
customers and 1,500 current DPL commercial natural gas customers will be able to
choose a natural gas supplier other than DPL.  DPL's large commercial and
industrial customers already have the ability to choose their natural gas
suppliers.

Electric Revenues
- -----------------

Details of the changes in the various components of electric revenues for the
first quarter of 1999 compared to the first quarter of 1998 are shown below
(dollars in millions):

                                            ======     ======   =====
</TABLE>

Consolidated electric revenues increased by $209.2 million, from $354.1 million
for the first quarter of 1998 to $563.3 million for the first quarter of 1999.
Merger-related customer base rate decreases reduced the increase in non-energy
(or base rate) revenues by approximately $2.4 million.  As shown in the table
above, ACE's electric revenues included in consolidated Conectiv electric
revenues increased $166.7 million, primarily due to inclusion of two additional
months of ACE's operating results in the current period.  On a pro forma basis,
as though Conectiv's operating results included ACE's operations beginning
January 1, 1998, regulated electric retail kilowatt-hour (kWh) sales and
customers increased 5.8% and 1.4%, respectively.  The pro forma sales increase
was primarily due to colder winter weather, which caused greater kWh usage than
last year for heating.

Currently, energy and interchange delivery revenues generally do not affect net
income due to energy adjustment clauses.  After restructuring becomes effective,
gross margins from supplying electricity (energy supply revenues less energy
costs) to current DPL customers are expected to affect earnings.  The New Jersey
energy adjustment clause is expected to be superseded by provisions contained in
the New Jersey Act which permit Basic Generation Service (BGS) suppliers full
and timely recovery of their costs.  The Act also authorizes the NJBPU to allow
the deferral and subsequent recovery of BGS costs if necessary for attainment of
the rate reductions required by the New Jersey Act.  Regulations governing BGS
are expected to be promulgated by the NJBPU prior to beginning retail choice of
electricity suppliers in New Jersey.

Revenues from electric sales not subject to price regulation increased $19.4
million, mainly due to more output sold off-system through DPL's Merchant
business.  Gross margin percentages earned in markets not subject to price
regulation are generally lower than the gross margin percentages earned in
regulated retail markets due to product differences, greater volume per
customer, and unregulated pricing.

Gas Revenues
- ------------

Total gas revenues increased by $176.1 million, from $115.8 million to $291.9
million.  Details of the changes in the various components of gas revenues for
the first quarter of 1999 compared to the first quarter of 1998 are shown below
(dollars in millions):

<TABLE>

          Energy revenues                       5.3
          Revenues from sales not subject
           to price regulation                168.5
                                             ------
            Total                            $176.1
                                             ======
</TABLE>

The increases shown above for non-energy and energy gas revenues were primarily
due to a 15.1% increase in residential gas sales (based on cubic feet sold) due
to colder winter weather which caused more cubic feet of gas to be used to
operate heating systems.  Gas energy revenues generally do not affect net income
due the energy adjustment clause, as discussed in Conectiv's 1998 report on Form
10-K, under "Gas Regulatory Matters" on page I-13.

Gas revenues from sales not subject to price regulation increased $168.5 million
mainly due to higher volumes of bulk gas sales.  The margin earned from non-
price regulated gas sales in excess of related purchased gas costs is relatively
small mainly due to the competitive nature of bulk commodity sales.

Other Services Revenues
- -----------------------

Other service revenues were comprised of the following:

(1) Refer to page I-3 of Conectiv's 1998 Report on Form 10-K for a description 
    of this business.

As shown in the preceding table, other services revenues increased to $91.4
million in the first quarter of 1999, from $33.7 million in the first quarter of
1998.  The $57.7 million revenue increase was mainly due to $37.5 million of
first quarter 1999 revenues from a business which sells fuel oil and gasoline
and was acquired by Conectiv late in the first quarter of 1998.  Revenues also
increased due to additional acquisitions of HVAC businesses, expansion of
Conectiv's telecommunications and energy solutions businesses, and two
additional months of operating results from the district heating and cooling
business of Conectiv Thermal Systems, Inc.  Conectiv Communications, Inc. had
sold about 42,000 access line equivalents as of March 31, 1999 in comparison to
32,000 access line equivalents as of December 31, 1998.

Operating Expenses
- ------------------

Electric Fuel and Purchased Energy

Electric fuel and purchased energy increased $92.9 million in the first quarter
of 1999, with the additional two months of ACE's operations in the current
period accounting for $50.3 million of the total increase.  The remaining $42.6
million of the increase was primarily due to more energy supplied for greater
volumes of electricity sold off-system and within DPL's and ACE's service
territories.

Gas Purchased

Gas purchased increased from $98.6 million to $271.6 million mainly due to
larger volumes of gas purchased for resale off-system and to satisfy higher on-
system sales demand due to the colder winter weather.

Other Services Cost of Sales
 
Other services cost of sales increased by $50.2 million primarily due to the
business acquisitions and expansions discussed under "Other Services Revenues."

Purchased Electric Capacity

Purchased electric capacity costs increased $27.5 million due to inclusion of
the two additional months of ACE's operations in the first quarter 1999.

Employee Separation and Other Merger-Related Costs

The costs for separated DPL employees and other Merger-related costs expensed in
the first quarter of 1998 were $40.6 million before taxes, reducing net income
and earnings per common share by $24.6 million and $0.33, respectively.
Employee separation, relocation, and other Merger-related costs for Atlantic's
former subsidiaries were capitalized as costs of the Merger.

Operation and Maintenance Expenses

After excluding the $35.5 million of operation and maintenance expenses
attributed to the two additional months of ACE's operations included in the
first quarter of 1999, operation and maintenance expenses decreased by $4.8
million.  This decrease resulted from a $15.1 million decrease for utility
operations, which was substantially offset by a $10.3 million increase for
nonutility operations.  Utility operations benefited from fewer employees, cost
control measures, and other Merger synergies.  The increase for nonutility
operations was primarily due to expansion of the telecommunications business and
also reflects higher expenses due to acquisitions and other business growth.

Depreciation and Taxes Other than Income Taxes

Depreciation and taxes other than income taxes increased principally due to
inclusion of the two additional months of operating results of ACE and other
former Atlantic-owned businesses in the first quarter of 1999.

                                      -21-
<PAGE>
 
Other Income
- ------------

Other income reflects a $16.0 million increase due to ATE's equity in earnings
of an investment partnership (Enertech).  This investment contributed $9.4
million to net income and $0.09 to earnings per common share.  Due to the nature
of Enertech's investments, which include internet service companies, its
earnings may be volatile from period to period.

Financing Costs
- ---------------

Financing costs reflected in the Consolidated Statements of Income include
interest charges, allowance for funds used during construction (AFUDC), and
preferred stock dividend requirements of subsidiaries.  Financing costs
increased $14.3 million primarily due to inclusion of two additional months of
operating results of ACE and other former Atlantic-owned businesses in the first
quarter of 1999.

Year 2000
- ----------

The Year 2000 issue is the result of computer programs and embedded systems
using a two-digit format, as opposed to four digits, to indicate the year.
Computer and embedded systems with this characteristic may be unable to
interpret dates during and beyond the year 1999, which could cause a system
failure or other computer errors, leading to disruption of operations.  A
project team, originally started in 1996 by ACE, is managing Conectiv's response
to this situation.  A Conectiv corporate officer, reporting directly to the
Chief Executive Officer, is coordinating all Year 2000 activities.  There are
substantial challenges in identifying and correcting the computer and embedded
systems critical to generating and delivering power, delivering natural gas and
providing other services to customers.

The project team is using a phased approach to managing its activities.  The
first phase is inventory and assessment of all systems, equipment, and
processes.  Each identified item was given a criticality rating of high, medium
or low.  Those items rated as high or medium are then subject to the second
phase of the project.  The second phase is determining and implementing
corrective action for the systems, equipment and processes, and concludes with a
test of the unit being remediated.  The third phase is system testing and
compliance certification.  Additionally, the project team is updating existing
outage contingency plans to address Year 2000 issues.

Overall, Conectiv's Year 2000 Project covers approximately 140 different systems
(some with numerous components) that had been originally identified as high or
medium in criticality.  However, only 21 of those 140 systems are essential for
Conectiv to provide electric and gas service to its customers.  The Year 2000
Project team is focusing on these 21 systems, with additional work on the other
systems continuing based on their relative importance to Conectiv's businesses.

The following chart sets forth the current estimated completion percentage of
the 140 different systems in the Year 2000 Project by major business group, and
for the information technology systems used in managing Conectiv's business.
Conectiv expects to continue to see significant progress in remediation and
testing over the next quarter based on work that is in process and material that
has been ordered or already received.

Conectiv is also contacting vendors and service providers to review remediation
of their Year 2000 issues. Many aspects of Conectiv's businesses are dependent
on third parties.  For example, fuel suppliers must be able to provide coal or
gas to allow Conectiv's subsidiaries to generate electricity.

Distribution of electricity is dependent on the overall reliability of the
electric grid.  ACE and DPL are cooperating with the North American Electric
Reliability Council (NERC) and the PJM Interconnection in Year 2000 remediation
and contingency planning efforts.  Recent reports issued by NERC indicate a
diminished risk of disruption to the electric grid caused by Year 2000 issues.
Conectiv's Year 2000 Project timeline is generally in-line with the
recommendations of those groups.  Two small DPL generating units for which
remediation will be complete by June, 1999, are scheduled for testing in
September to coincide with a previously scheduled outage.  These units represent
about 4% of Conectiv's generating capacity and will be tested earlier if an
appropriate outage occurs.  Testing that has already taken place at similar
units that have been remediated indicated no Year 2000 problems.

In addition, Conectiv participated in the first of two NERC drills on April 9,
1999; a small number of manageable issues were identified and are being
addressed.  The Company will also participate in the second NERC drill set for
September 9, 1999 and will conduct its own drill.

Conectiv has incurred approximately $5.7 million in costs for the Year 2000
Project.  Current estimates of the costs for the Year 2000 Project range from
$10 million to $15 million.  These estimates could change significantly as the
Year 2000 Project progresses.  The costs set forth above do not include several
significant expenditures covering new systems, such as Conectiv's SAP business,
financial and human resources management system and an Energy Control System.
While these new systems effectively remediated Year 2000 problems in the systems
they replaced, Conectiv is not reporting the expenditures on these systems in
its costs for the Year 2000 Project, because the new systems were installed
principally for other reasons.

Since the project team is still in the process of assessing and correcting
impacted systems, equipment and processes, Conectiv cannot with certainty
determine whether the Year 2000 issue might cause disruptions to its operations
and impact related costs and revenues.  Conectiv assesses the status of the Year
2000 Project on at least a monthly basis to determine the likelihood of
disruption.  Based on its own Year 2000 program, as well as reports from NERC
and other utilities, Conectiv's management believes it is unlikely that
significant Year 2000 related disruption will occur.  However, any substantial
disruption to Conectiv's operations could negatively impact Conectiv's revenues,
significantly impact its customers and could generate legal claims against
Conectiv.  Conectiv's results of operations and financial position would likely
suffer an adverse impact if other entities, such as suppliers, customers and
service providers do not effectively address their Year 2000 issues.

Liquidity and Capital Resources
- -------------------------------

Cash and cash equivalents increased by $36.2 million during the first quarter of
1999.  Operating activities provided $149.0 million of net cash which was used
primarily to pay for $58.9 million of capital expenditures and $43.7 million of
common dividends.

Net cash provided by operating activities for the first quarter of 1999
increased by $55.9 million from the first quarter of 1998.  The increase was
primarily due to the two additional months of ACE's operations included in the
consolidated financial statements, cost reductions, and higher electric and gas
revenues, net of amounts paid for related energy costs.

Primarily due to over-collections of energy costs from utility customers,
Conectiv's consolidated liability for deferred energy costs was $51.6 million as
of March 31, 1999.  These over-collections of energy costs will be returned to
customers via lower energy rates, which will reduce net cash provided by
operating activities as the energy businesses of DPL and ACE are restructured.

Capital expenditures for the first quarter of 1999 were $58.9 million compared
to $28.4 million for the first quarter of 1998.  The $30.5 million increase in
capital expenditures was primarily due to construction of a new customer service
center, higher expenditures for other shared infrastructure assets, and
expansion of Conectiv Communications, Inc.'s telecommunications system.  The
$10.3 million of "Investments in partnerships" reflects Conectiv Thermal
Systems' share of funding for construction of the "Venetian" project in Las
Vegas, Nevada, and investments in Enertech by ATE.

Common dividends paid increased from $23.6 million for the first quarter of 1998
to $43.7 million for the first quarter of 1999, mainly due to the additional
shares of common stock outstanding in the first quarter of 1999 due to the
Merger.

Conectiv's capital structure as of March 31, 1999 and December 31, 1998,
expressed as a percentage of total capitalization is shown below.

Long-term debt and variable rate demand bonds         46.1%          46.8%
</TABLE>

Current maturities of long-term debt increased $45.9 million primarily due to
scheduled maturities of ACE's Medium Term Notes.

Conectiv, the holding company, increased its credit lines with banks from $500
million as of December 31, 1998, to $800 million as of March 31, 1999.  Two
credit agreements provide the $800 million of borrowing capability as follows:
(a) a $300 million credit agreement which has a five-year term that expires in
February 2003; and (b) a $500 million credit agreement which has a one-year term
that expires in February 2000.

Item 5.  Other Information
- --------------------------

The following information updates the disclosure regarding Air Quality
Regulations on page I-15 of Conectiv's 1998 Report on Form 10-K.

On March 1, 1999, the State of Delaware Department of Natural Resources and
Environmental Control (DNREC) re-issued final "post-RACT" NOx control
regulations requiring attainment of summer seasonal emission reductions of up to
65% below 1990 levels by May 1999 through reduced emissions or the procurement
of NOx emission allowances.  DPL is working toward compliance with the
regulations by installing control technology and trying to secure NOx
allowances.  The short time period between initial proposal of the regulations
in October 1997 and the May 1999 compliance date, uncertainty regarding the
successful implementation of control technologies in the short term, inadequate
time for development of an allowance trading market and the regulations'
stringent penalties for non-compliance, have prompted DPL to challenge the
regulations before the Environmental Appeals Board and in Delaware Superior
Court.  Management cannot predict the outcome of this litigation.

Similar post-RACT regulations issued in Maryland were vacated in February 1999
by the Maryland Circuit Court for Baltimore City in response to a challenge by
other Maryland utilities.  Accordingly, DPL's Maryland units are not required to
comply with post-RACT requirements during the 1999 summer ozone season.

     debt of either ACE or Delmarva. For purposes of the foregoing, (i) if

     be in the business of rating corporate debt obligations, the Borrower and
     the Lenders shall negotiate in good faith to amend this definition to
     reflect such changed rating system or the unavailability of ratings from
     such Rating Agency, and, pending the effectiveness of

made on the effective date thereof, (a) the aggregate principal amount of the
Loans then outstanding, when added to the then outstanding L/C Obligations,
would exceed the Commitments then in effect or (b) the Aggregate Availability
would be less than zero.  Any such reduction shall be in an amount equal to

any such account, or any error therein, shall not in any manner affect the
obligation of the Borrower to repay (with applicable interest) the Loans made to
such Borrower by such Lender in accordance with the terms of this Agreement.

          (e)  The Borrower agrees that, upon the request to the Administrative
Agent by any Lender, the Borrower will execute and deliver to such Lender a
promissory note of the Borrower evidencing the Loans of such Lender,
substantially in the form of Exhibit A with appropriate insertions as to date
and principal amount (a "Note").
                         ----   

          2.6  Optional Prepayments.  The Borrower may at any time and from time
               --------------------                                             
to time prepay the Loans, in whole or in part, without premium or penalty, upon
at least three Business Days' irrevocable notice to the Administrative Agent,
specifying the date and amount of prepayment and whether the prepayment is of
Eurodollar Loans, C/D Rate Loans, ABR Loans or a combination thereof, and, if of
a combination thereof, the amount allocable to each.  Upon receipt of any such
notice the Administrative Agent shall promptly notify each Lender thereof.  If
any such notice is given, the amount specified in such notice shall be due and
payable on the date specified therein, together with any amounts payable
pursuant to subsection 2.16 and accrued 

                                       18
<PAGE>
 
interest to such date on the amount prepaid. Partial prepayments shall be in an
aggregate principal amount of $5,000,000 or a whole multiple of $1,000,000 in
excess thereof.

          2.7  Conversion and Continuation Options. (a)  The Borrower may elect
               -----------------------------------                             
from time to time to convert Eurodollar Loans or C/D Rate Loans to ABR Loans,
and/or to convert Eurodollar Loans or ABR Loans to C/D Rate Loans, by giving the
Administrative Agent at least two Business Days' prior irrevocable notice of
such election, provided that any such conversion of Eurodollar Loans or C/D Rate
               --------                                                         
Loans may only be made on the last day of an Interest Period with respect
thereto.  The Borrower may elect from time to time to convert ABR Loans or C/D
Rate Loans to Eurodollar Loans by giving the Administrative Agent at least three
Business Days' prior irrevocable notice of such election, provided that any such
                                                          --------              
conversion of C/D Rate Loans may, subject to the third succeeding sentence, only
be made on the last day of an Interest Period with respect thereto.  Any such
notice of conversion to Eurodollar Loans or C/D Rate Loans shall specify the
length of the initial Interest Period or Interest Periods therefor.  Upon
receipt of any such notice the Administrative Agent shall promptly notify each
Lender thereof.  If the last day of the then current Interest Period with
respect to C/D Rate Loans that are to be converted to Eurodollar Loans is not a
Business Day, such conversion shall be made on the next succeeding Business Day,
and during the period from such last day to such succeeding Business Day such
Loans shall bear interest as if they were ABR Loans.  All or any part of
outstanding Eurodollar Loans, ABR Loans and C/D Rate Loans may be converted as
provided herein, provided that (i) no Loan may be converted into a Eurodollar
                 --------                                                    
Loan or a C/D Rate Loan when any Event of Default has occurred and is continuing
and the Administrative Agent has or the Majority Lenders have determined that
such a conversion is not appropriate and (ii) no Loan may be converted into a
Eurodollar Loan or a C/D Rate Loan after the date that is one month or 30 days,
respectively, prior to the Termination Date.

          (b)  Any Eurodollar Loans or C/D Rate Loans may be continued as such
upon the expiration of the then current Interest Period with respect thereto by
the Borrower giving notice to the Administrative Agent, in accordance with the
applicable provisions of the term "Interest Period" set forth in subsection 1.1,
of the length of the next Interest Period to be applicable to such Loans,
                                                                         
provided that no Eurodollar Loan or C/D Rate Loan may be continued as such (i)
- --------                                                                      
when any Event of Default has occurred and is continuing and the Administrative
Agent has or the Majority Lenders have determined that such a continuation is
not appropriate or (ii) after the date that is one month or 30 days prior to,
respectively, the Termination Date and provided, further, that if the Borrower
                                       --------  -------                      
shall fail to give such notice or if such continuation is not permitted such
Loans shall be automatically converted to ABR Loans on the last day of such then
expiring Interest Period.

          2.8  Minimum Amounts and Maximum Number of Tranches.  All borrowings,
               ----------------------------------------------                  
conversions and continuations of Loans hereunder and all selections of Interest
Periods hereunder shall be in such amounts and be made pursuant to such
elections so that, after giving effect thereto, the aggregate principal amount
of the Loans comprising (i) each Eurodollar Tranche shall be equal to $5,000,000
or a whole multiple of $1,000,000 in excess thereof and (ii) 

                                       19
<PAGE>
 
each C/D Rate Tranche shall be equal to $5,000,000 or a whole multiple of
$1,000,000 in excess thereof. In no event shall there be more than 16 Eurodollar
Tranches or 16 C/D Rate Tranches outstanding at any time.

          2.9  Interest Rates and Payment Dates.  (a)  Each Eurodollar Loan
               --------------------------------                            
shall bear interest for each day during each Interest Period with respect
thereto at a rate per annum equal to the Eurodollar Rate determined for such day
plus the Applicable Margin.

          (b)  Each ABR Loan shall bear interest at a rate per annum equal to
the ABR plus the Applicable Margin.

          (c)  Each C/D Rate Loan shall bear interest for each day during each
Interest Period with respect thereto at a rate per annum equal to the C/D Rate
determined for such day plus the Applicable Margin.

          (d)  If all or a portion of (i) any principal of any Loan, (ii) any
interest payable thereon, (iii) any commitment fee, (iv) any other amount
payable hereunder shall not be paid when due (whether at the stated maturity, by
acceleration or otherwise) or (v) any other Event of Default shall have occurred
and be continuing, the principal of the Loans and any such overdue interest,
commitment fee or other amount shall bear interest at a rate per annum which is
(x) in the case of principal, the rate that would otherwise be applicable
thereto pursuant to the foregoing provisions of this subsection plus 2% or (y)
in the case of any such overdue interest, commitment fee or other amount, the
rate described in paragraph (b) of this subsection plus 2%, in each case from
the date of such non-payment until such overdue principal, interest, commitment
fee or other amount is paid in full (as well after as before judgment).

          (e)  Interest shall be payable in arrears on each Interest Payment
Date and on the Termination Date, provided that interest accruing pursuant to
                                  --------                                   
paragraph (d) of this subsection shall be payable from time to time on demand.

          2.10  Computation of Interest and Fees.  (a) Commitment fees and,
                --------------------------------                           
whenever it is calculated on the basis of the Corporate Base Rate, interest
shall be calculated on the basis of a 365- (or 366-, as the case may be) day
year for the actual days elapsed; and, otherwise, interest shall be calculated
on the basis of a 360-day year for the actual days elapsed.  The Administrative
Agent shall as soon as practicable notify the Borrower and the Lenders of each
determination of a Eurodollar Rate or of a C/D Rate.  Any change in the interest
rate on a Loan resulting from a change in the ABR, the Eurocurrency Reserve
Requirements, the C/D Assessment Rate or the C/D Reserve Percentage shall become
effective as of the opening of business on the day on which such change becomes
effective.  The Administrative Agent shall as soon as practicable notify the
Borrower and the Lenders of the effective date and the amount of each such
change in interest rate.

                                       20
<PAGE>
 
          (b)  Each determination of an interest rate by the Administrative
Agent pursuant to any provision of this Agreement shall be conclusive and
binding on the Borrower and the Lenders in the absence of manifest error. The
Administrative Agent shall, at the request of the Borrower, deliver to the
Borrower a written statement showing the quotations used by the Administrative
Agent in determining any interest rate pursuant to subsection 2.9(a) or (c).

          2.11  Inability to Determine Interest Rate.  If prior to the first day
                ------------------------------------                            
of any Interest Period:

          (a)  the Administrative Agent shall have determined (which
     determination shall be conclusive and binding upon the Borrower) that, by
     reason of circumstances affecting the relevant market, adequate and
     reasonable means do not exist for ascertaining the Eurodollar Rate or the
     C/D Rate for such Interest Period, or

          (b)  the Administrative Agent shall have received notice from the
     Majority Lenders that the Eurodollar Rate or the C/D Rate determined or to
     be determined for such Interest Period will not adequately and fairly
     reflect the cost to such Lenders (as conclusively certified by such
     Lenders) of making or maintaining their affected Loans during such Interest
     Period,

the Administrative Agent shall give telecopy or telephonic notice thereof to the
Borrower and the Lenders as soon as practicable thereafter.  If such notice is
given (x) any Eurodollar Loans or C/D Rate Loans, as the case may be, requested
to be made on the first day of such Interest Period shall be made as ABR Loans,
(y) any Loans that were to have been converted on the first day of such Interest
Period to Eurodollar Loans or C/D Rate Loans, as the case may be, shall be
converted to or continued as ABR Loans and (z) any outstanding Eurodollar Loans
or C/D Rate Loans, as the case may be, that were to have been continued as such
on such first day shall be converted on such day to ABR Loans.  Until such
notice has been withdrawn by the Administrative Agent, no further Eurodollar
Loans or C/D Rate Loans, as the case may be, shall be made or continued as such,
nor shall the Borrower have the right to convert Loans to Eurodollar Loans or
C/D Rate Loans, as the case may be.

          2.12  Pro Rata Treatment and Payments.  (a)  Each borrowing by the
                -------------------------------                             
Borrower from the Lenders hereunder, each payment by the Borrower on account of
any commitment fee hereunder and any reduction of the Commitments of the Lenders
shall be made pro rata according to the respective Commitment Percentages of the
Lenders.  Each payment (including each prepayment) by the Borrower on account of
principal of and interest on the Loans shall be made pro rata according to the
respective outstanding principal amounts of the Loans then held by the Lenders.
All payments (including prepayments) to be made by the Borrower hereunder,
whether on account of principal, interest, fees or otherwise, shall be made
without set off, counterclaim or other deduction and shall be made prior to
12:00 Noon, Chicago time, on the due date thereof to the Administrative Agent,
for the account of the Lenders, at the Administrative Agent's office specified
in subsection 10.2, in Dollars and in immediately available funds.  The 

                                       21
<PAGE>
 
Administrative Agent shall distribute such payments to the Lenders promptly upon
receipt in like funds as received.  If any payment hereunder becomes due and
payable on a day other than a Business Day, such payment shall be extended to
the next succeeding Business Day, and, with respect to payments of principal,
interest thereon shall be payable at the then applicable rate during such
extension.

          (b)  Unless the Administrative Agent shall have been notified in
writing by any Lender prior to a borrowing that such Lender will not make the
amount that would constitute its Commitment Percentage of such borrowing
available to the Administrative Agent, the Administrative Agent may assume that
such Lender is making such amount available to the Administrative Agent, and the
Administrative Agent may, in reliance upon such assumption, make available to
the Borrower a corresponding amount.  If such amount is not made available to
the Administrative Agent by the required time on the Borrowing Date therefor,
such Lender shall pay to the Administrative Agent, on demand, such amount with
interest thereon at a rate equal to the daily average Federal Funds Effective
Rate for the period until such Lender makes such amount immediately available to
the Administrative Agent.  A certificate of the Administrative Agent submitted
to any Lender with respect to any amounts owing under this subsection shall be
conclusive in the absence of manifest error.  If such Lender's Commitment
Percentage of such borrowing is not made available to the Administrative Agent
by such Lender within three Business Days of such Borrowing Date, the
Administrative Agent shall also be entitled to recover such amount with interest
thereon at the rate per annum applicable to ABR Loans hereunder, on demand, from
the Borrower.

          2.13  Illegality.  Notwithstanding any other provision herein, if the
                ----------                                                     
adoption of or any change in any Requirement of Law or in the interpretation or
application thereof shall make it unlawful for any Lender to make or maintain
Eurodollar Loans as contemplated by this Agreement, (a) the commitment of such
Lender hereunder to make Eurodollar Loans, continue Eurodollar Loans as such and
convert Domestic Dollar Loans to Eurodollar Loans shall forthwith be canceled
and (b) such Lender's Loans then outstanding as Eurodollar Loans, if any, shall
be converted automatically to ABR Loans on the respective last days of the then
current Interest Periods with respect to such Loans or within such earlier
period as required by law.  If any such conversion of a Eurodollar Loan occurs
on a day which is not the last day of the then current Interest Period with
respect thereto, the Borrower shall pay to such Lender such amounts, if any, as
may be required pursuant to subsection 2.16.

          2.14  Requirements of Law.  (a)  If the adoption of or any change in
                -------------------                                           
any Requirement of Law or in the interpretation or application thereof or
compliance by any Lender with any request or directive (whether or not having
the force of law) from any central bank or other Governmental Authority made
subsequent to the date hereof:

          (i)  shall subject any Lender to any tax of any kind whatsoever with
     respect to this Agreement, any Note, any Letter of Credit, any Application
     or any Eurodollar Loan or C/D Rate Loan made by it, or change the basis of
     taxation of payments to such Lender in 

                                       22
<PAGE>
 
     respect thereof (except for Non-Excluded Taxes covered by subsection 2.15
     and changes in the rate of tax on the overall net income of such Lender);

               (ii)  shall impose, modify or hold applicable any reserve,
     special deposit, compulsory loan or similar requirement against assets held
     by, deposits or other liabilities in or for the account of, advances, loans
     or other extensions of credit by, or any other acquisition of funds by, any
     office of such Lender which is not otherwise included in the determination
     of the Eurodollar Rate or the C/D Rate hereunder; or

               (iii) shall impose on such Lender any other condition;

and the result of any of the foregoing is to increase the cost to such Lender,
by an amount which such Lender deems to be material, of making, converting into,
continuing or maintaining Eurodollar Loans or C/D Rate Loans or issuing or
participating in Letters of Credit or to reduce any amount receivable hereunder
in respect thereof, then, in any such case, the Borrower shall pay such Lender
such additional amount or amounts as will compensate such Lender for such
increased cost or reduced amount receivable within 15 days following
notification of such increased cost or reduced amount receivable pursuant to
subsection 2.14(c) below, provided that such increased cost or reduced amount
                          --------                                           
receivable shall be compensated only to the extent incurred during the 90 day
period prior to the notification of the Borrower by such Lender of such
increased cost or reduced amount receivable.

          (b)  If any Lender shall have determined that the adoption of or any
change in any Requirement of Law regarding capital adequacy or in the
interpretation or application thereof or compliance by such Lender or any
corporation controlling such Lender with any request or directive regarding
capital adequacy (whether or not having the force of law) from any Governmental
Authority made subsequent to the date hereof shall have the effect of reducing
the rate of return on such Lender's or such corporation's capital as a
consequence of its obligations hereunder or under any Letter of Credit to a
level below that which such Lender or such corporation could have achieved but
for such adoption, change or compliance (taking into consideration such Lender's
or such corporation's policies with respect to capital adequacy) by an amount
deemed by such Lender to be material, then from time to time, the Borrower shall
pay to such Lender such additional amount or amounts as will compensate such
Lender for such reduction within 15 days following notification of such
reduction pursuant to subsection 2.14(c) below, provided that such reduction
                                                --------                    
shall be compensated only to the extent incurred during the 90 day period prior
to the notification of the Borrower by such Lender of such reduction.

          (c) If any Lender becomes entitled to claim any additional amounts
pursuant to this subsection, it shall promptly notify the Borrower (with a copy
to the Administrative Agent) of the event by reason of which it has become so
entitled.  A certificate as to any additional amounts payable pursuant to this
subsection submitted by such Lender to the Borrower (with a copy to the
Administrative Agent) shall be conclusive in the absence of 

                                       23
<PAGE>
 
manifest error. The agreements in this subsection shall survive the termination
of this Agreement and the payment of the Loans and all other amounts payable
hereunder.

          2.15  Taxes.  (a)  All payments made by the Borrower under this
                -----                                                    
Agreement and any Notes shall be made free and clear of, and without deduction
or withholding for or on account of, any present or future income, stamp or
other taxes, levies, imposts, duties, charges, fees, deductions or withholdings,
now or hereafter imposed, levied, collected, withheld or assessed by any
Governmental Authority, excluding net income taxes and franchise taxes (imposed
in lieu of net income taxes) imposed on the Administrative Agent or any Lender
as a result of a present or former connection between the Administrative Agent
or such Lender and the jurisdiction of the Governmental Authority imposing such
tax or any political subdivision or taxing authority thereof or therein (other
than any such connection arising solely from the Administrative Agent or such
Lender having executed, delivered or performed its obligations or received a
payment under, or enforced, this Agreement or any Note).  If any such non-
excluded taxes, levies, imposts, duties, charges, fees deductions or
withholdings ("Non-Excluded Taxes") are required to be withheld from any amounts
               ------------------                                               
payable to the Administrative Agent or any Lender hereunder or under any Note,
the amounts so payable to the Administrative Agent or such Lender shall be
increased to the extent necessary to yield to the Administrative Agent or such
Lender (after payment of all Non-Excluded Taxes) interest or any such other
amounts payable hereunder at the rates or in the amounts specified in this
Agreement, provided, however, that the Borrower shall not be required to
           --------  -------                                            
increase any such amounts payable to any Lender that is not organized under the
laws of the United States of America or a state thereof if such Lender fails to
comply with the requirements of paragraph (b) of this subsection.  Whenever any
Non-Excluded Taxes are payable by the Borrower, as promptly as possible
thereafter the Borrower shall send to the Administrative Agent for its own
account or for the account of such Lender, as the case may be, a certified copy
of an original official receipt received by the Borrower showing payment
thereof.  If the Borrower fails to pay any Non-Excluded Taxes when due to the
appropriate taxing authority or fails to remit to the Administrative Agent the
required receipts or other required documentary evidence, the Borrower shall
indemnify the Administrative Agent and the Lenders for any incremental taxes,
interest or penalties that may become payable by the Administrative Agent or any
Lender as a result of any such failure.  The agreements in this subsection shall
survive the termination of this Agreement and the payment of the Loans and all
other amounts payable hereunder.

          (b)  Each Lender that is not incorporated under the laws of the United
States of America or a state thereof shall:

          (i)  deliver to the Borrower and the Administrative Agent (A) two duly
     completed copies of United States Internal Revenue Service Form 1001 or
     4224, or successor applicable form, as the case may be, and (B) an Internal
     Revenue Service Form W-8 or W-9, or successor applicable form, as the case
     may be;

                                       24
<PAGE>
 
               (ii)  deliver to the Borrower and the Administrative Agent two
     further copies of any such form or certification on or before the date that
     any such form or certification expires or becomes obsolete and after the
     occurrence of any event requiring a change in the most recent form
     previously delivered by it to the Borrower; and

               (iii) obtain such extensions of time for filing and complete
     such forms or certifications as may reasonably be requested by the Borrower
     or the Administrative Agent;

unless in any such case an event (including, without limitation, any change in
treaty, law or regulation) has occurred prior to the date on which any such
delivery would otherwise be required which renders all such forms inapplicable
or which would prevent such Lender from duly completing and delivering any such
form with respect to it and such Lender so advises the Borrower and the
Administrative Agent.  Such Lender shall certify (i) in the case of a Form 1001
or 4224, that it is entitled to receive payments under this Agreement without
deduction or withholding of any United States federal income taxes and (ii) in
the case of a Form W-8 or W-9, that it is entitled to an exemption from United
States backup withholding tax.  Each Person that shall become a Lender or a
Participant pursuant to subsection 9.6 shall, upon the effectiveness of the
related transfer, be required to provide all of the forms and statements
required pursuant to this subsection, provided that in the case of a Participant
such Participant shall furnish all such required forms and statements to the
Lender from which the related participation shall have been purchased.

          2.16  Indemnity.  The Borrower agrees to indemnify each Lender and to
                ---------                                                      
hold each Lender harmless from any loss or expense which such Lender may sustain
or incur as a consequence of (a) default by the Borrower in making a borrowing
of, conversion into or continuation of Eurodollar Loans or C/D Rate Loans after
the Borrower has given a notice requesting the same in accordance with the
provisions of this Agreement, (b) default by the Borrower in making any
prepayment after the Borrower has given a notice thereof in accordance with the
provisions of this Agreement or (c) the making of a prepayment of Eurodollar
Loans or C/D Rate Loans on a day which is not the last day of an Interest Period
with respect thereto.  Such indemnification may include an amount equal to the
excess, if any, of (i) the amount of interest which would have accrued on the
amount so prepaid, or not so borrowed, converted or continued, for the period
from the date of such prepayment or of such failure to borrow, convert or
continue to the last day of such Interest Period (or, in the case of a failure
to borrow, convert or continue, the Interest Period that would have commenced on
the date of such failure) in each case at the applicable rate of interest for
such Loans provided for herein (excluding, however, the Applicable Margin
included therein, if any) over (ii) the amount of interest (as reasonably
determined by such Lender) which would have accrued to such Lender on such
amount by placing such amount on deposit for a comparable period with leading
banks in the interbank eurodollar market.  This covenant shall survive the
termination of this Agreement and the payment of the Loans and all other amounts
payable hereunder.

          2.17  Change of Lending Office.  Each Lender agrees that if it makes
                ------------------------                                      
any demand for payment under subsection 2.14 or 2.15(a), or if any adoption or
change of the type described in subsection 2.13 shall occur with respect to it,
it will use reasonable efforts (consistent with its internal policy and legal
and regulatory restrictions and so long as such efforts would not be
disadvantageous to it, as determined in its sole discretion) to designate a
different lending office if the making of such a designation would reduce or
obviate the need for the Borrower to make payments under subsection 2.14 or
2.15(a), or would eliminate or reduce the effect of any adoption or change
described in subsection 2.13.

          2.18  Extension of Maturity Date.  (a)  Not less than 60 days and not
                --------------------------                                     
more than 90 days prior to the Termination Date then in effect, provided that no
Event of Default shall have occurred and be continuing, the Borrower may request
an extension of such Termination Date by submitting to the Administrative Agent
an Extension Request containing the information in respect of such extension
specified in Exhibit B, which the Administrative Agent shall promptly furnish to
each Lender.  Each Lender shall, not less than 30 days and not more than 45 days
prior to the Termination Date then in effect, notify the Borrower and the
Administrative Agent of its election to extend or not extend the Termination
Date as requested in such Extension Request.  Notwithstanding any provision of
this Agreement to the contrary, any notice by any Lender of its willingness to
extend the Termination Date shall be revocable by such Lender in its sole and
absolute discretion at any time prior to the date which is 30 days prior to the
Termination Date then in effect.  If the then Majority Lenders shall approve in
writing the extension of the Termination Date requested in such Extension
Request, the Termination Date shall automatically and without any further action
by any Person be extended for the period specified in such Extension Request;
provided that (i) each extension pursuant to this subsection shall be for a
- --------                                                                   
maximum of 364 days and (ii) the Commitment of any Lender that does not consent
in writing to such extension not less than 30 days and not more than 45 days
prior to the Termination Date then in effect (an "Objecting Lender") shall,
                                                  ----------------         
unless earlier terminated in accordance with this Agreement, expire on the
Termination Date in effect on the date of such Extension Request (such
Termination Date, if any, referred to as the "Commitment Expiration Date" with
                                              --------------------------      
respect to such Objecting Lender).  If, not less than 30 days and not more than
45 days prior to the Termination Date then in effect, the then Majority Lenders
shall not approve in writing the extension of the Termination Date requested in
an Extension Request, the Termination Date shall not be extended pursuant to
such Extension Request.  The Administrative Agent shall promptly notify (y) the
Lenders and the Borrower of any extension of the Termination Date pursuant to
this subsection and (z) the Borrower and each other Lender of any Lender which
becomes an Objecting Lender.

          (b)  Loans owing to any Objecting Lender on the Commitment Expiration
Date with respect to such Lender shall be repaid in full on or before such
Commitment Expiration Date.

          (c)  The Borrower may, at its sole expense and effort, upon notice to
any Objecting Lender or any Lender who is an "Objecting Lender" as defined in
the Other Credit Agreement (an "Other Objecting Lender") and the Administrative
                                ----------------------                         
Agent, require such Objecting

<PAGE>
 
Lender or Other Objecting Lender, as the case may be, to assign and delegate,
without recourse (in accordance with and subject to the restrictions contained
in subsection 10.6), all its interests, rights and obligations under this
Agreement to an assignee that shall assume such obligations (which assignee may
be another Lender, if a Lender accepts such assignment); provided that (i) the
                                                         --------
Borrower shall have received the prior written consent of the Administrative
Agent and the Issuing Bank (unless such Objecting Lender or Other Objecting
Lender is the Administrative Agent or an Issuing Bank, in which case its consent
shall not be required), which consents shall not unreasonably be withheld, (ii)
such Objecting Lender or Other Objecting Lender, as the case may be, shall have
received payment of an amount equal to the outstanding principal of its Loans
and participations in Letter of Credit disbursements, accrued interest thereon,
accrued fees and all other amounts payable to it hereunder, from the assignee
(to the extent of such outstanding principal and accrued interest and fees) or
the Borrower (in the case of all other amounts).

          (d)  For a period of 90 days following any extension of the
Termination Date pursuant to this subsection 2.18, the Borrower may, at its sole
expense and effort, upon notice to the Administrative Agent, cause additional
banks or other financial institutions to become parties hereto as Lenders to
replace the Commitments of Objecting Lenders no longer parties hereto, provided
                                                                       --------
that the aggregate Commitments shall not exceed the aggregate Commitments
existing prior to such extension.  Such additional banks or other financial
institutions shall be subject to the approval of the Administrative Agent and
the Issuing Bank (the consent of which will not be unreasonably withheld) and
shall become parties hereto by executing such supplements hereto as shall be
satisfactory to the Borrower and the Administrative Agent.  Upon any such bank
or other financial institution so becoming a Lender the Borrower will effect
such borrowings and prepayments as are necessary to cause all then outstanding
Loans to be held ratably by all the Lenders.

          2.19  Telephonic Notices.  The Borrower hereby authorizes the Lenders
                ------------------
and the Administrative Agent to extend, convert or continue Loans, effect
selections of Types of Loans and to transfer funds based on telephonic notices
made by any person or persons the Administrative Agent or any Lender in good
faith believes to be a Responsible Officer or manager of corporate markets
acting on behalf of the Borrower. The Borrower agrees to deliver promptly to the
Administrative Agent a written confirmation, if such confirmation is requested
by the Administrative Agent or any Lender, of each telephonic notice signed by a
Responsible Officer. If the written confirmation differs in any material respect
from the action taken by the Administrative Agent and the Lenders, the records
of the Administrative Agent and the Lenders shall govern absent manifest error.


                         SECTION 3.  LETTERS OF CREDIT

          3.1  L/C Commitment.
               -------------- 

                                       27
<PAGE>
 
          (a   Subject to the terms and conditions hereof, the Issuing Bank, in
reliance on the agreements of the other Lenders set forth in subsection 3.4(a),
agrees to issue letters of credit ("Letters of Credit") for the account of the
                                    -----------------                         
Borrower on any Business Day during the Commitment Period in such form as may be
approved from time to time by the Issuing Bank; provided that the Issuing Bank
                                                --------                      
shall have no obligation to issue any Letter of Credit if, after giving effect
to such issuance, (i) the L/C Obligations would exceed the L/C Commitment or
(ii) the Available Commitment of any Lender would be less than zero.

          (b   Each Letter of Credit shall:

          (i0  be denominated in Dollars and shall be a standby letter of credit
                                                        ------------------------
     issued to support obligations of the Borrower or any Subsidiary, contingent
     or otherwise, and

          (ii0  expire no later than the earlier of (A) the date that is 364
     days from the date of issue of such Letter of Credit and (B) the date which
     is ten days prior to the Termination Date.

          (c   Each Letter of Credit shall be subject to the Uniform Customs or
The International Standby Practices (ISP98) and, to the extent not inconsistent
therewith, the laws of the State of New York.

          (d)  The Issuing Bank shall not at any time be obligated to issue any
Letter of Credit hereunder if such issuance would conflict with, or cause the
Issuing Bank or any L/C Participant to exceed any limits imposed by, any
applicable Requirement of Law.

          3.2  Procedure for Issuance of Letters of Credit.
               ------------------------------------------- 

          The Borrower may from time to time request that the Issuing Bank issue
a Letter of Credit by delivering to the Issuing Bank at its address for notices
specified herein an Application therefor, completed to the satisfaction of the
Issuing Bank, and such other certificates, documents and other papers and
information as the Issuing Bank may request. Upon receipt of any Application,
the Issuing Bank will process such Application and the certificates, documents
and other papers and information delivered to it in connection therewith in
accordance with its customary procedures and shall promptly issue the Letter of
Credit requested thereby (but in no event shall the Issuing Bank be required to
issue any Letter of Credit earlier than three Business Days after its receipt of
the Application therefor and all such other certificates, documents and other
papers and information relating thereto) by issuing the original of such Letter
of Credit to the beneficiary thereof or as otherwise may be agreed by the
Issuing Bank and the Borrower. The Issuing Bank shall furnish a copy of such
Letter of Credit to the Borrower promptly following the issuance thereof.

          3.3  Fees and Other Charges.  (a)  The Borrower will pay a fee on the
               ----------------------                                          
maximum amount available from time to time for drawing under all outstanding
Letters of Credit at a rate 

                                       28
<PAGE>
 
per annum (calculated for actual days elapsed on the basis of a year of 360
days) equal to the Applicable Margin then in effect for Eurodollar Loans
hereunder. Such fee shall be payable to the Administrative Agent, to be shared
ratably among the L/C Participants, quarterly in arrears on each L/C Fee Payment
Date after the issuance date. In addition, the Borrower shall pay to the Issuing
Bank for its own account a fronting fee with respect to each Letter of Credit as
set forth in that certain letter agreement between the Borrower and the Issuing
Bank dated February 11, 1999 or as otherwise agreed from time to time.

          (b   In addition to the foregoing fees and commissions, the Borrower
shall pay or reimburse the Issuing Bank for such normal and customary costs and
expenses as are incurred or charged by the Issuing Bank in issuing, negotiating,
effecting payment under, amending or otherwise administering any Letter of
Credit.

          3.4  L/C Participations.
               ------------------ 

          (a   The Issuing Bank irrevocably agrees to grant and hereby grants to
each L/C Participant, and, to induce the Issuing Bank to issue Letters of Credit
hereunder, each L/C Participant irrevocably agrees to accept and purchase and
hereby accepts and purchases from the Issuing Bank, on the terms and conditions
hereinafter stated, for such L/C Participant's own account and risk an undivided
interest equal to such L/C Participant's Commitment Percentage in the Issuing
Bank's obligations and rights under each Letter of Credit issued hereunder and
the amount of each draft paid by the Issuing Bank thereunder. Each L/C
Participant unconditionally and irrevocably agrees with the Issuing Bank that,
if a draft is paid under any Letter of Credit for which the Issuing Bank is not
reimbursed in full by the Borrower in accordance with the terms of this
Agreement, such L/C Participant shall pay to the Issuing Bank upon demand at the
Issuing Bank's address for notices specified herein an amount equal to such L/C
Participant's Commitment Percentage of the amount of such draft, or any part
thereof, which is not so reimbursed.  Each L/C Participant acknowledges and
agrees that its obligation to acquire participations pursuant to this paragraph
in respect of Letters of Credit is absolute and unconditional and shall not be
affected by any circumstances whatsoever, including the occurrence and
continuance of a Default or an Event of Default or the termination of the
Commitments, and that each such payment shall be made without any offset,
abatement, withholding or reduction whatsoever.

          (b   If any amount required to be paid by any L/C Participant to the
Issuing Bank pursuant to subsection 3.4(a) in respect of any unreimbursed
portion of any payment made by the Issuing Bank under any Letter of Credit is
not paid to the Issuing Bank when due but is paid to the Issuing Bank within
three Business Days after the date such payment is due, such L/C Participant
shall pay to the Issuing Bank on demand an amount equal to the product of (i)
such amount, times (ii) the daily average Federal funds rate, as quoted by the
Issuing Bank, during the period from and including the date such payment is
required to the date on which such payment is immediately available to the
Issuing Bank, times (iii) a fraction the numerator of which is the number of
days that elapse during such period and the denominator of which is 360. If any
such 

                                       29
<PAGE>
 
amount required to be paid by any L/C Participant pursuant to subsection 3.4(a)
is not in fact made available to the Issuing Bank by such L/C Participant within
three Business Days after the date such payment is due, the Issuing Bank shall
be entitled to recover from such L/C Participant, on demand, such amount with
interest thereon calculated from such due date at the rate per annum applicable
to ABR Loans hereunder. A certificate of the Issuing Bank submitted to any L/C
Participant with respect to any amounts owing under this subsection shall be
conclusive in the absence of manifest error.

          (c   Whenever, at any time after the Issuing Bank has made payment
under any Letter of Credit and has received from any L/C Participant its pro
rata share of such payment in accordance with subsection 3.4(a), the Issuing
Bank receives any payment related to such Letter of Credit (whether directly
from the Borrower or otherwise, including proceeds of collateral applied thereto
by the Issuing Bank), or any payment of interest on account thereof, the Issuing
Bank will distribute to such L/C Participant its pro rata share thereof;
provided, however, that in the event that any such payment received by the
- --------  -------                                                         
Issuing Bank shall be required to be returned by the Issuing Bank, such L/C
Participant shall return to the Issuing Bank the portion thereof previously
distributed by the Issuing Bank to it.

          3.5  Reimbursement Obligation of the Borrower.
               ---------------------------------------- 

          (a   The Borrower agrees to reimburse the Issuing Bank on each date on
which the Issuing Bank notifies the Borrower of the date and amount of a draft
presented under any Letter of Credit and paid by the Issuing Bank for the amount
of (i) such draft so paid and (ii) any taxes, fees, charges or other costs or
expenses incurred by the Issuing Bank in connection with such payment. Each such
payment shall be made to the Issuing Bank at its address for notices specified
herein in Dollars and in immediately available funds.

          (b   Interest shall be payable on any and all amounts remaining unpaid
by the Borrower under this subsection from the date such amounts become payable
(whether at stated maturity, by acceleration or otherwise) until payment in full
at the rate which would be payable on any outstanding ABR Loans which were then
overdue.

          (c   Each drawing under any Letter of Credit shall constitute a
request by the Borrower to the Administrative Agent for a borrowing pursuant to
subsection 2.2 of ABR Loans in the amount of such drawing. The Borrowing Date
with respect to such borrowing shall be the date of such drawing.

          3.6  Obligations Absolute.
               -------------------- 

          (a   The Borrower's obligations under this Section 3 shall be absolute
and unconditional under any and all circumstances and irrespective of any set-
off, counterclaim or defense to payment which the Borrower may have or have had
against the Issuing Bank or any beneficiary of a Letter of Credit.

                                       30
<PAGE>
 
          (b   The Borrower also agrees with the Issuing Bank that the Issuing
Bank shall not be responsible for, and the Borrower's Reimbursement Obligations
under subsection 3.5(a) shall not be affected by, among other things, (i) the
validity or genuineness of documents or of any endorsements thereon, even though
such documents shall in fact prove to be invalid, fraudulent or forged (subject,
however, to the provisions of subsection 3.6(d)), or (ii) any dispute between or
among the Borrower and any beneficiary of any Letter of Credit or any other
party to which such Letter of Credit may be transferred or (iii) any claims
whatsoever of the Borrower against any beneficiary of such Letter of Credit or
any such transferee.

          (c   The Issuing Bank shall not be liable for any error, omission,
interruption or delay in transmission, dispatch or delivery of any message or
advice, however transmitted, in connection with any Letter of Credit, except for
errors or omissions caused by the Issuing Bank's gross negligence or willful
misconduct.

          (d   The Borrower agrees that any action taken or omitted by the
Issuing Bank under or in connection with any Letter of Credit or the related
drafts or documents, if done in the absence of gross negligence or willful
misconduct and in accordance with the standards of care specified in the Uniform
Commercial Code of the State of New York, shall be binding on the Borrower and
shall not result in any liability of the Issuing Bank to the Borrower.

          3.7  Letter of Credit Payments.
               ------------------------- 

          If any draft shall be presented for payment under any Letter of
Credit, the Issuing Bank shall promptly notify the Borrower of the date and
amount thereof. The responsibility of the Issuing Bank to the Borrower in
connection with any draft presented for payment under any Letter of Credit
shall, in addition to any payment obligation expressly provided for in such
Letter of Credit, be limited to determining that the documents (including each
draft) delivered under such Letter of Credit in connection with such presentment
are in conformity with such Letter of Credit.

          3.8  Application.
               ----------- 

          To the extent that any provision of any Application related to any
Letter of Credit is inconsistent with the provisions of this Section 3, the
provisions of this Section 3 shall apply.


                  SECTION 4.  REPRESENTATIONS AND WARRANTIES

          To induce the Lenders to enter into this Agreement and to make the
Loans and issue or participate in the Letters of Credit, the Borrower hereby
represents and warrants to the Administrative Agent and each Lender that:

                                       31
<PAGE>
 
          4.1  Financial Condition.  The unaudited consolidated balance sheet of
               -------------------                                              
the Borrower, ACE and Delmarva and their respective consolidated Subsidiaries as
at September 30, 1998 and the related unaudited consolidated statements of
income and of cash flows for the nine-month period then ended, certified by a
Responsible Officer, copies of which have heretofore been furnished to each
Lender, are complete and correct and present fairly the consolidated financial
condition of the Borrower, ACE and Delmarva and their respective consolidated
Subsidiaries as at such date, and the consolidated results of their operations
and their consolidated cash flows for the period then ended (subject to normal
year-end audit adjustments).  All such financial statements, including the
related schedules and notes thereto, have been prepared in accordance with GAAP
applied consistently throughout the periods involved (except as approved by such
accountants or Responsible Officer, as the case may be, and as disclosed
therein).  Neither the Borrower, ACE and Delmarva nor any of their respective
consolidated Subsidiaries had, at the date of the most recent balance sheet
referred to above, any material Guarantee Obligation, contingent liability or
liability for taxes, or any long-term lease or unusual forward or long-term
commitment, including, without limitation, any interest rate or foreign currency
swap or exchange transaction, which is not reflected in the foregoing statements
or in the notes thereto.

          4.2  No Change.  Since September 30, 1998 there has been no
               ---------

standing under the laws of the jurisdiction of its organization, (b) has the
corporate power and authority, and the legal right, to own and operate its
property, to lease the property it operates as lessee and to conduct the
business in which it is currently engaged, (c) is duly qualified as a foreign
corporation and in good standing under the laws of each jurisdiction where its
ownership, lease or operation of property or the conduct of its business
requires such qualification and (d) is in compliance with all Requirements of
Law, except to the extent that the failure to comply with clauses (a) through
(d) above would not, in the aggregate, reasonably be expected to have a Material
Adverse Effect.

          4.4  Corporate Power; Authorization; Enforceable Obligations.  (a)
               -------------------------------------------------------       
The Borrower has the corporate power and authority, and the legal right, to
make, deliver and perform this Agreement and each other Loan Document and to
borrow hereunder and has taken all necessary corporate action to authorize the
borrowings on the terms and conditions of this Agreement and each other Loan
Document and to authorize the execution, delivery and performance of this
Agreement, the Notes and the Applications and each other Loan Document to which
it is a party.

          (b  Except for the consent from the Securities and Exchange
Commission, a copy of which is attached as Schedule 4.4, no consent or
authorization of, approval by, notice to, filing with or other act by or in
respect of, any Governmental Authority (including, without limitation, the
United States Securities and Exchange Commission under the Public Utility
Holding Company Act of 1935, as amended) or any other Person is required in
connection with the 

                                       32
<PAGE>
 
borrowings hereunder or with the execution, delivery, performance, validity or
enforceability of this Agreement or any other Loan Document.

          (c   This Agreement has been, and each other Loan Document will be,
duly executed and delivered on behalf of the Borrower.

          (d  This Agreement constitutes, and each other Loan Document when
executed and delivered will constitute, a legal, valid and binding obligation of
the Borrower enforceable against the Borrower in accordance with its terms,
except as affected by bankruptcy, insolvency, fraudulent conveyance,
reorganization, moratorium and other similar laws relating to the enforcement of
creditors' rights generally and general equitable principles (whether considered
in a proceeding in equity or at law).

          4.5  No Legal Bar.  The execution, delivery and performance of this
               ------------                                                  
Agreement, any Applications and any Notes, the borrowings hereunder and the use
of the proceeds thereof will not violate any Requirement of Law or material
Contractual Obligation of the Borrower or of any of its Subsidiaries and will
not result in, or require, the creation or imposition of any Lien on any of its
or their respective properties or revenues pursuant to any such Requirement of
Law or Contractual Obligation.

          4.6  No Material Litigation.  Except as heretofore disclosed to the
               ----------------------                                        
Lenders by the Borrower (a) in its financial statements referred to in
subsection 4.1 or (b) in quarterly or other periodic reports filed with the
United States Securities and Exchange Commission copies of which have been
delivered to the Lenders prior to the date hereof, no litigation, investigation
or proceeding of or before any arbitrator or Governmental Authority is pending
or, to the knowledge of the Borrower, threatened by or against the Borrower or
any of its Subsidiaries or against any of its or their respective properties or
revenues which could reasonably be expected to have a Material Adverse Effect.

          4.7  Ownership of Property; Liens.  Each of the Borrower and its
               ----------------------------                               
Subsidiaries has good record and marketable title in fee simple to, or a valid
leasehold interest in, all its real property, and good title to, or a valid
leasehold interest in, all its other property, except to the extent that the
failure to have such title or leasehold interest could not, in the aggregate,
reasonably be expected to have a Material Adverse Effect, and none of such
property is subject to any Lien except as permitted by subsection 7.2.

          4.8  Taxes.  Each of the Borrower and its Subsidiaries has filed or
               -----                                                         
caused to be filed all tax returns which, to the knowledge of the Borrower, are
required to be filed and has paid all taxes shown to be due and payable on said
returns or on any assessments made against it or any of its property and all
other taxes, fees or other charges imposed on it or any of its property by any
Governmental Authority (other than any the amount or validity of which are
currently being contested in good faith by appropriate proceedings and with
respect to which reserves in conformity with GAAP have been provided on the
books of the Borrower or its 

                                       33
<PAGE>
 
Subsidiaries, as the case may be), except to the extent that the failure to file
such tax returns or pay such taxes, fees and other charges would not, in the
aggregate, reasonably be expected to have a Material Adverse Effect.

          4.9  Federal Regulations.  No part of the proceeds of any Loans will
               -------------------                                            
be used in any manner that would result in a violation of Regulation G or
Regulation U of the Board of Governors of the Federal Reserve System as now and

          4.10  ERISA.  Neither a Reportable Event nor an "accumulated funding
                -----                                                         
deficiency" (within the meaning of Section 412 of the Code or Section 302 of
ERISA) has occurred during the five-year period prior to the date on which this
representation is made or deemed made with respect to any Plan, and each Plan
has complied in all material respects with the applicable provisions of ERISA
and the Code.  No termination of a Single Employer Plan has occurred, and no
Lien in favor of the PBGC or a Plan has arisen, during such five-year period.
The present value of all accrued benefits under each Single Employer Plan (based
on those assumptions used to fund such Plans) did not, as of the last annual
valuation date prior to the date on which this representation is made or deemed
made, exceed the value of the assets of such Plan allocable to such accrued
benefits.  Neither the Borrower nor any Commonly Controlled Entity has had a
complete or partial withdrawal from any Multiemployer Plan, and neither the
Borrower nor any Commonly Controlled Entity would become subject to any
liability under ERISA if the Borrower or any such Commonly Controlled Entity
were to withdraw completely from all Multiemployer Plans as of the valuation
date most closely preceding the date on which this representation is made or
deemed made.  No such Multiemployer Plan is in Reorganization or Insolvent.

          4.11  Investment Company Act.  The Borrower is not an "investment
                ----------------------                                     
company", or a company "controlled" by an "investment company", within the
meaning of the Investment Company Act of 1940, as amended.

          4.12  Purpose of Loans.  The proceeds of the Loans shall be used by
                ----------------                                             
the Borrower for general corporate purposes.

          4.13  Environmental Matters.  In the ordinary course of its business,
                ---------------------                                          
the officers of the Borrower consider the effect of Environmental Laws on the
business of the Borrower and its Subsidiaries, in the course of which they
identify and evaluate potential risks and liabilities accruing to the Borrower
due to Environmental Laws.  On the basis of this consideration, the Borrower has
reasonably concluded that Environmental Laws cannot reasonably be expected to
have a Material Adverse Effect.  Neither the Borrower nor any Subsidiary has
received any notice to the effect that its operations are not in material
compliance with any of the requirements of applicable Environmental Laws or are
the subject of any federal or state investigation evaluating whether any
remedial action is needed to respond to a release of any toxic or hazardous
waste or substance into the environment, which non-compliance or remedial action
could reasonably be expected to have a Material Adverse Effect.

affected by, and have developed and are implementing a program (the "Year 2000

or are planning to make appropriate inquiries as to the effect the Year 2000
Problem will have on their material suppliers and customers.  Based on such
review, program and inquiries, the Borrower reasonably believes that the Year
2000 Problem will not have a Material Adverse Effect.

Credit shall have presented the documents required thereunder) and any Notes
shall immediately become due and payable, and (B) if such event is any other

collateral to secure all obligations of the Borrower under this Agreement and
the other Loan Documents. Amounts held in such cash collateral account shall be
applied by the Administrative Agent to the payment of drafts drawn under such
Letters of Credit, and the unused portion thereof after all such Letters of
Credit shall have expired or been fully drawn upon, if any, shall be applied to
repay other obligations of the Borrower hereunder and under any Notes. After all
such Letters of Credit shall have expired or been fully drawn upon, all
Reimbursement Obligations shall have been satisfied and all other obligations of
the Borrower hereunder and under any Notes shall have been paid in full, the

collateral account.

     Except as expressly provided above in this Section, presentment, demand,
protest and all other notices of any kind are hereby expressly waived.


                            SECTION 9.  THE AGENTS

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

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

          9.3  General Immunity.  Neither the Administrative Agent nor any of
               ----------------                                              
its directors, officers, agents or employees shall be liable to the Borrower,
the Lenders or any Lender for any action taken or omitted to be taken by it or
them hereunder or under any other Loan Document or in connection herewith or
therewith except to the extent such action or inaction is determined in a 

                                       47
<PAGE>
 
final non-appealable judgment by a court of competent jurisdiction to have
arisen from the gross negligence or willful misconduct of such Person.

          9.4  No Responsibility for Loans, Recitals, etc.  Neither the
               -------------------------------------------             
Administrative Agent nor any of its directors, officers, agents or employees
shall be responsible for or have any duty to ascertain, inquire into, or verify
(a) any statement, warranty or representation made in connection with any Loan
Document or any borrowing hereunder; (b) the performance or observance of any of
the covenants or agreements of any obligor under any Loan Document, including,
without limitation, any agreement by an obligor to furnish information directly
to each Lender; (c) the satisfaction of any condition specified in Section 5,
except receipt of items required to be delivered solely to the Administrative
Agent; (d) the existence or possible existence of any Default or Event of
Default; (e) the validity, enforceability, effectiveness, sufficiency or
genuineness of any Loan Document or any other instrument or writing furnished in
connection therewith (except as may relate to the execution by the
Administrative Agent of any Loan Document); (f) the value, sufficiency,
creation, perfection or priority of any Lien in any collateral security; or (g)
the financial condition of the Borrower or any guarantor of any of the
Obligations or of any of the Borrower's or any such guarantor's respective
Subsidiaries.  The Administrative Agent shall have no duty to disclose to the
Lenders information that is not required to be furnished by the Borrower to the
Administrative Agent at such time, but is voluntarily furnished by the Borrower
to the Administrative Agent (either in its capacity as Administrative Agent or
in its individual capacity).

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

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

          9.8  Administrative Agent's Reimbursement and Indemnification'.  The
               ---------------------------------------------------------      
Lenders agree to reimburse and indemnify the Administrative Agent ratably in
proportion to their respective Commitments (or, if the Commitments have been
terminated, in proportion to their Commitments immediately prior to such
termination) (i) for any amounts not reimbursed by the Borrower for which the
Administrative Agent is entitled to reimbursement by the Borrower under the Loan
Documents, (ii) for any other expenses incurred by the Administrative Agent on
behalf of the Lenders, in connection with the preparation, execution, delivery,

limitation, for any expenses incurred by the Administrative Agent in connection
with any dispute between the Administrative Agent and any Lender or between two
or more of the Lenders) and (iii) for any liabilities, obligations, losses,
damages, penalties, actions, judgments, suits, costs, expenses or disbursements
of any kind and nature whatsoever which may be imposed on, incurred by or
asserted against the Administrative Agent in any way relating to or arising out
of the Loan Documents or any other document delivered in connection therewith or

such amounts incurred by or asserted against the Administrative Agent in
connection with any dispute between the Administrative Agent and any Lender or
between two or more of the Lenders), or the enforcement of any of the terms of
the Loan Documents or of any such other documents, provided that no Lender shall
                                                   --------                     
be liable for any of the foregoing to the extent any of the foregoing is found
in a final non-appealable judgment by a court of competent jurisdiction to have
resulted from the gross negligence or willful misconduct of the Administrative
Agent.  The obligations of the Lenders under this subsection 9.8 shall survive
payment of the Obligations and termination of this Agreement.

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

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

                                       49
<PAGE>
 
other Loan Document, with the Borrower or any of its Subsidiaries in which the
Borrower or such Subsidiary is not restricted hereby from engaging with any
other Person. The Administrative Agent, in its individual capacity, is not
obligated to remain a Lender.

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

          9.12  Successor Administrative Agent.  The Administrative Agent may
                ------------------------------                               
resign at any time by giving written notice thereof to the Lenders and the
Borrower, such resignation to be effective upon the appointment of a successor
Administrative Agent or, if no successor Administrative Agent has been
appointed, forty-five days after the retiring Administrative Agent gives notice
of its intention to resign.  The Administrative Agent may be removed at any time
with or without cause by written notice received by the Administrative Agent
from the Majority Lenders, such removal to be effective on the date specified by
the Majority Lenders.  Upon any such resignation or removal, the Majority
Lenders shall have the right to appoint, on behalf of the Borrower and the
Lenders, a successor Administrative Agent.  If no successor Administrative Agent
shall have been so appointed by the Majority Lenders within thirty days after
the resigning Administrative Agent's giving notice of its intention to resign,
then the resigning Administrative Agent may appoint, on behalf of the Borrower
and the Lenders, a successor Administrative Agent.  Notwithstanding the previous
sentence, the Administrative Agent may at any time without the consent of the
Borrower or any Lender, appoint any of its Affiliates which is a commercial bank
as a successor Administrative Agent hereunder.  If the Administrative Agent has
resigned or been removed and no successor Administrative Agent has been
appointed, the Lenders may perform all the duties of the Administrative Agent
hereunder and the Borrower shall make all payments in respect of the Obligations
to the applicable Lender and for all other purposes shall deal directly with the
Lenders.  No successor Administrative Agent shall be deemed to be appointed
hereunder until such successor Administrative Agent has accepted the
appointment.  Any such successor Administrative Agent shall be a commercial bank
having capital and retained earnings of at least $100,000,000.  Upon the
acceptance of any appointment as Administrative Agent hereunder by a successor
Administrative Agent, such successor Administrative Agent shall thereupon
succeed to and become vested with all the rights, powers, privileges and duties
of the resigning or removed Administrative Agent.  Upon the effectiveness of the
resignation or removal of the Administrative Agent, the resigning or removed
Administrative Agent shall be discharged from any future duties and obligations
hereunder and under the Loan Documents.  After the effectiveness of the
resignation or removal of an Administrative Agent, the provisions of this
Section 9 shall continue in effect for the benefit of 

                                       50
<PAGE>
 
such Administrative Agent in respect of any actions taken or omitted to be taken
by it while it was acting as the Administrative Agent hereunder and under the
other Loan Documents.

          9.13  Administrative Agent's Fee.'  The Borrower agrees to pay to the
                -------------------------- -                                   
Administrative Agent, for its own account, the fees agreed to by the Borrower
and the Administrative Agent pursuant to the term sheet referred to in the
commitment letter among the Borrower, First Chicago and First Chicago Capital
Markets, Inc. dated January 15, 1999 or as otherwise agreed in writing from time
to time.

          9.14  Delegation to Affiliates.  The Borrower and the Lenders agree
                ------------------------                                     
that the Administrative Agent may delegate any of its duties under this
Agreement to any of its Affiliates.  Any such Affiliate (and such Affiliate's
directors, officers, agents and employees) which performs duties in connection
with this Agreement shall be entitled to the same benefits of the
indemnification, waiver and other protective provisions to which the
Administrative Agent is entitled under Sections 9 and 10.

          9.15 The Syndication Agent, the Documentation Agent and the Arranger.
               ---------------------------------------------------------------  
None of the Syndication Agent, the Documentation Agent or the Arranger, in such
capacities, shall have any duties, responsibilities, obligations, liabilities or
functions under this Agreement or the other Loan Documents.  Each Lender
acknowledges that it has not relied, and will not rely, on any of the
Syndication Agent, the Documentation Agent or the Arranger in deciding to enter
into this Agreement or in taking or refraining from taking any action hereunder
or pursuant hereto.

Loan Document, nor any terms hereof or thereof may be amended, supplemented or

Documents for the purpose of adding any provisions to this Agreement or the
other Loan Documents or changing in any manner the rights of the Lenders or of
the Borrower hereunder or thereunder or (b) waive, on such terms and conditions
as the Majority Lenders or the Administrative Agent, as the case may be, may
specify in such instrument, any of the requirements of this Agreement or the
other Loan Documents or any Default or Event of Default and its consequences;

maturity of any Loan or of any installment thereof or any Reimbursement
Obligation with respect to any Letter of Credit, or reduce the stated rate of
any interest or fee payable hereunder or extend the scheduled date of any
payment thereof or increase the amount or extend the expiration date of any
Lender's Commitment, in each case without the consent of each Lender affected
thereby, or (ii) amend, modify or waive any provision of this subsection or
reduce the percentage specified in the definition of Majority Lenders, or
consent to the assignment or transfer by the Borrower of any of its rights and
obligations under this Agreement and the other Loan Documents, in each case
without the written consent of all the Lenders, or (iii) amend any provision of
Section 3 or any Application without the written consent of the Issuing Bank, or
(iv) amend, modify or waive any provision of Section 9 or any other provision
relating to the Administrative Agent without the written consent of the then
Administrative Agent.  Any such waiver and any such amendment, supplement or
modification shall apply equally to each of the Lenders and shall be binding
upon the Borrower, the Lenders, the Administrative Agent and all future holders
of the Loans.  In the case of any waiver, the Borrower, the Lenders and the
Administrative Agent shall be restored to their former positions and rights
hereunder and under the other Loan Documents, and any Default or Event of
Default waived shall be deemed to be cured and not continuing; no such waiver
shall extend to any subsequent or other Default or Event of Default or impair
any right consequent thereon.

          10.6  Successors and Assigns; Participations and Assignments.  (a)
                ------------------------------------------------------       
This Agreement shall be binding upon and inure to the benefit of the Borrower,
the Lenders, the Administrative Agent and their respective successors and
assigns, except that the Borrower may not assign or transfer any of its rights
or obligations under this Agreement without the prior written consent of each
Lender.

          (b)  Any Lender may, in the ordinary course of its commercial banking
business and in accordance with applicable law, at any time sell to one or more
banks or other entities ("Participants") participating interests in any Loan
                          ------------                                      
owing to such Lender, any Commitment of such Lender or any other interest of
such Lender hereunder and under the other Loan Documents; provided that, in the
                                                          --------             
case of any such sale of a participating interest, the aggregate amount of the
L/C Obligations and the aggregate amount of the Available Commitment being
assigned is not less than $5,000,000 (or such lesser amount as may be agreed to
by the Administrative Agent).  In the event of any such sale by a Lender of a
participating interest to a Participant, such Lender's obligations under this
Agreement to the other parties to this Agreement shall remain unchanged, such
Lender shall remain solely responsible for the performance thereof, such Lender
shall remain the holder of any such Loan for all purposes under this Agreement
and the other Loan Documents, and the Borrower and the Administrative Agent
shall continue to deal solely and directly with such Lender in connection with
such Lender's rights and obligations under this Agreement and the other Loan
Documents.  No Lender shall be entitled to create in favor of any Participant,
in the participation agreement pursuant to which such Participant's
participating interest shall be created or otherwise, any right to vote on,
consent to or approve any matter relating to this Agreement or any other Loan
Document except for those specified in clauses (i) 

                                       54
<PAGE>
 
and (ii) of the proviso to subsection 10.1. The Borrower agrees that if amounts
outstanding under this Agreement are due or unpaid, or shall have been declared
or shall have become due and payable upon the occurrence of an Event of Default,
each Participant shall, to the maximum extent permitted by applicable law, be
deemed to have the right of setoff 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 Lender under this
Agreement, provided that, in purchasing such participating interest, such
           --------
Participant shall be deemed to have agreed to share with the Lenders the
proceeds thereof as provided in subsection 10.7(a) as fully as if it were a
Lender hereunder. The Borrower also agrees that each Participant shall be
entitled to the benefits of subsections 2.14, 2.15 and 2.16 with respect to its
participation in the Commitments and the Loans outstanding from time to time as
if it was a Lender; provided that, in the case of subsection 2.15, such
                    --------
Participant shall have complied with the requirements of said subsection and
provided, further, that no Participant shall be entitled to receive any greater
- --------  -------
amount pursuant to any such subsection than the transferor Lender would have
been entitled to receive in respect of the amount of the participation
transferred by such transferor Lender to such Participant had no such transfer
occurred.

          (c)  Any Lender may, in the ordinary course of its commercial banking
business and in accordance with applicable law, at any time and from time to
time assign to any Lender or any Affiliate thereof or, with the consent of the
Borrower, each Issuing Bank and the Administrative Agent (which in each case
shall not be unreasonably withheld), to an additional bank or financial
institution (an "Assignee") all or any part of its rights and obligations under
                 --------                                                      
this Agreement and the other Loan Documents pursuant to an Assignment and
Acceptance, substantially in the form of Exhibit D, executed by such Assignee,
such assigning Lender (and, in the case of an Assignee that is not then a Lender
or an Affiliate thereof, by the Borrower, each Issuing Bank and the
Administrative Agent) and delivered to the Administrative Agent for its
acceptance and recording in the Register, provided that, in the case of any such
                                          --------                              
assignment to an additional bank or financial institution, the sum of the
aggregate principal amount of the Loans, the aggregate amount of the L/C
Obligations and the aggregate amount of the Available Commitment being assigned
is not less than $5,000,000 (or such lesser amount as may be agreed to by the
Borrower and the Administrative Agent) or all of such Lender's Loans, rights and
obligations hereunder.  Upon such execution, delivery, acceptance and recording,
from and after the effective date determined pursuant to such Assignment and
Acceptance, (x) the Assignee thereunder shall be a party hereto and, to the
extent provided in such Assignment and Acceptance, have the rights and
obligations of a Lender hereunder with a Commitment as set forth therein, and
(y) the assigning Lender thereunder shall, to the extent provided in such
Assignment and Acceptance, be released from its obligations under this Agreement
(and, in the case of an Assignment and Acceptance covering all or the remaining
portion of an assigning Lender's rights and obligations under this Agreement,
such assigning Lender shall cease to be a party hereto).  Notwithstanding any
provision of this paragraph (c) and paragraph (e) of this subsection, the
consent of the Borrower shall not be required, and, unless requested by the
Assignee and/or the assigning Lender, new Notes shall not be required to be
executed and 

                                       55
<PAGE>
 
delivered by the Borrower, for any assignment which occurs at any time when any
Event of Default shall have occurred and be continuing.

          (d)  The Administrative Agent, on behalf of the Borrower, shall
maintain at the address of the Administrative Agent referred to in subsection
10.2 a copy of each Assignment and Acceptance delivered to it and a register
(the "Register") for the recordation of the names and addresses of the Lenders
      --------                                                                
and the Commitment of, and principal amounts of the Loans owing to, each Lender
from time to time.  The entries in the Register shall be conclusive, in the
absence of manifest error, and the Borrower, the Administrative Agent and the
Lenders may (and, in the case of any Loan or other obligation hereunder not
evidenced by a Note, shall) treat each Person whose name is recorded in the
Register as the owner of a Loan or other obligation hereunder as the owner
thereof for all purposes of this Agreement and the other Loan Documents,
notwithstanding any notice to the contrary.  Any assignment of any Loan or other
obligation hereunder not evidenced by a Note shall be effective only upon
appropriate entries with respect thereto being made in the Register.

          (e)  Upon its receipt of an Assignment and Acceptance executed by an
assigning Lender and an Assignee (and, in the case of an Assignee that is not
then a Lender or an Affiliate thereof, by the Borrower and the Administrative
Agent) together with payment to the Administrative Agent of a registration and
processing fee of $3,000, the Administrative Agent shall (i) promptly accept
such Assignment and Acceptance and (ii) on the effective date determined
pursuant thereto record the information contained therein in the Register and
give notice of such acceptance and recordation to the Lenders and the Borrower.

          (f)  The Borrower authorizes each Lender to disclose to any
Participant or Assignee (each, a "Transferee") and any prospective Transferee,
                                  ----------                                  
subject to the provisions of subsection 10.15, any and all financial information
in such Lender's possession concerning the Borrower and its Affiliates which has
been delivered to such Lender by or on behalf of the Borrower pursuant to this
Agreement or which has been delivered to such Lender by or on behalf of the
Borrower in connection with such Lender's credit evaluation of the Borrower and
its Affiliates prior to becoming a party to this Agreement.

          (g) For avoidance of doubt, the parties to this Agreement acknowledge
that the provisions of this subsection concerning assignments of Loans and Notes
relate only to absolute assignments and that such provisions do not prohibit
assignments creating security interests, including, without limitation, any
pledge or assignment by a Lender of any Loan or Note to any Federal Reserve Bank
in accordance with applicable law.

          (h) Notwithstanding anything to the contrary contained herein, any
Lender (a "Granting Lender") may grant to a special purpose funding vehicle (a
           ---------------                                                    
"SPC"), identified as such in writing from time to time by the Granting Lender
 ---                                                                          
to the Administrative Agent and the Borrower, the option to provide to the
Borrower all or any part of any Loan that such Granting Lender would otherwise
be obligated to make to the Borrower pursuant to this Agreement; 

                                       56

provided that (i) nothing herein shall constitute a commitment by any SPC to
- --------
make any Loan and (ii) if an SPC elects not to exercise such option or otherwise
fails to provide all or any part of such Loan, the Granting Lender shall be
obligated to make such Loan pursuant to the terms hereof. The making of a Loan
by an SPC hereunder shall utilize the Commitment of the Granting Lender to the
same extent, and as if, such Loan were made by such Granting Lender. Each party
hereto agrees that no SPC shall be liable for any indemnity or similar payment
obligation under this Agreement (all liability for which shall remain with the
Granting Lender). In furtherance of the foregoing, each party hereto agrees
(which agreement shall survive the termination of this Agreement) that, prior to
the date that is one year and one day after the payment in full of all
outstanding commercial paper or other senior indebtedness of any SPC, it will
not institute against, or join any other person in instituting against, such SPC
any bankruptcy, reorganization, arrangement, insolvency or liquidation
proceeding under the laws of the United States or any State thereof. In
addition, notwithstanding anything to the contrary contained in this subsection
10.6, any SPC may (i) with notice to, but without the prior written consent of,
the Borrower and the Administrative Agent and without paying any processing fee
therefor, assign all or a portion of its interests in any Loans to the Granting
Lender or to any financial institutions (consented to by the Borrower and
Administrative Agent) providing liquidity and/or credit support to or for the
account of such SPC to support the funding or maintenance of Loans and (ii)
disclose on a confidential basis any non-public information relating to its
Loans to any rating agency, commercial paper dealer or provider of any surety,
guarantee or credit or liquidity enhancement to such SPC.

          10.7  Adjustments; Set-off-.  (a)  If any Lender (a "benefitted
                ---------------------                          ----------
Lender") at any time shall receive any payment of all or part of its Loans or
- ------
the Reimbursement Obligations owing to it, or interest thereon, or receive any
collateral in respect thereof (whether voluntarily or involuntarily, by set-off,
pursuant to events or proceedings of the nature referred to in Section 8(f) or
otherwise), in a greater proportion than any such payment to or collateral
received by any other Lender, if any, in respect of such other Lender's Loans or
the Reimbursement Obligations owing to it, or interest thereon, such benefitted
Lender shall purchase for cash from the other Lenders such portion of each such
other Lender's Loan or the Reimbursement Obligations owing to it, or shall
provide such other Lenders with the benefits of any such collateral, or the
proceeds thereof, as shall be necessary to cause such benefitted Lender to share
the excess payment or benefits of such collateral or proceeds ratably with each
of the Lenders; provided, however, that if all or any portion of such excess
                --------  -------                                           
payment or benefits is thereafter recovered from such benefitted Lender, such
purchase shall be rescinded, and the purchase price and benefits returned, to
the extent of such recovery, but without interest. The Borrower agrees that each
Lender so purchasing a portion of another Lender's Loan may exercise all rights
of payment (including, without limitation, rights of set-off) with respect to
such portion as fully as if such Lender were the direct holder of such portion.

          (b)  In addition to any rights and remedies of the Lenders provided by
law, each Lender shall have the right, without prior notice to the Borrower, any
such notice being expressly waived by the Borrower to the extent permitted by
applicable law, upon any amount becoming 

                                       57
<PAGE>
 
due and payable by the Borrower hereunder (whether at the stated maturity, by
acceleration or otherwise) to set-off and appropriate and apply against such
amount any and all deposits (general or special, time or demand, provisional or
final), in any currency, and any other credits, indebtedness or claims, in any
currency, in each case whether direct or indirect, absolute or contingent,
matured or unmatured, at any time held or owing by such Lender or any branch or
agency or Affiliate thereof to or for the credit or the account of the Borrower.
Each Lender agrees promptly to notify the Borrower and the Administrative Agent
after any such set-off and application made by such Lender, provided that the
                                                            --------
failure to give such notice not affect the validity of such set-off
and application.

          10.8  Counterparts.  This Agreement may be executed by one or more of
                ------------                                                   
the parties to this Agreement on any number of separate counterparts (including
by facsimile transmission), and all of said counterparts taken together shall be
deemed to constitute one and the same instrument.  A set of the copies of this
Agreement signed by all the parties shall be lodged with the Borrower and the
Administrative Agent.

          10.9  Severability.  Any provision of this Agreement which is
                ------------                                           
prohibited or unenforceable in any jurisdiction shall, as to such jurisdiction,
be ineffective to the extent of such prohibition or unenforceability without
invalidating the remaining provisions hereof, and any such prohibition or
unenforceability in any jurisdiction shall not invalidate or render
unenforceable such provision in any other jurisdiction.

          10.10  Integration.  This Agreement and the other Loan Documents
                 -----------                                              
represent the entire agreement of the Borrower, the Administrative Agent and the
Lenders with respect to the subject matter hereof and supersedes all prior
agreements, understandings, negotiations and discussions, whether oral or
written, of the parties hereto relating to the subject matter hereof, and there
are no promises, undertakings, representations or warranties by the
Administrative Agent or any Lender relative to subject matter hereof not
expressly set forth or referred to herein or in the other Loan Documents.

OF THE PARTIES HEREUNDER SHALL BE GOVERNED BY, AND CONSTRUED AND INTERPRETED IN
ACCORDANCE WITH, THE INTERNAL SUBSTANTIVE LAW OF THE STATE OF NEW YORK WITHOUT
REGARD TO CONFLICTS OF LAWS PRINCIPLES.

          10.12  Submission To Jurisdiction; Waivers.  The Borrower hereby
                 -----------------------------------                      
irrevocably and unconditionally:

          (a)  submits for itself and its property in any legal action or
     proceeding relating to this Agreement and the other Loan Documents to which
     it is a party, or for recognition and enforcement of any judgement in
     respect thereof, to the non-exclusive general 

                                       58

     jurisdiction of the Courts of the State of New York, the courts of the
     United States of America for the Southern District of New York, and
     appellate courts from any thereof;

          (b)  consents that any such action or proceeding may be brought in
     such courts and waives any objection that it may now or hereafter have to
     the venue of any such action or proceeding in any such court or that such
     action or proceeding was brought in an inconvenient court and agrees not to
     plead or claim the same;

          (c)  agrees that service of process in any such action or proceeding
     may be effected by mailing a copy thereof by registered or certified mail
     (or any substantially similar form of mail), postage prepaid, to the
     Borrower at its address set forth in subsection 10.2 or at such other
     address of which the Administrative Agent shall have been notified pursuant
     thereto;

          (d)  agrees that nothing herein shall affect the right to effect
     service of process in any other manner permitted by law or shall limit the
     right to sue in any other jurisdiction; and

          (e)  waives, to the maximum extent not prohibited by law, any right it
     may have to claim or recover in any legal action or proceeding referred to
     in this subsection any special, exemplary, punitive or consequential
     damages.

          10.13  Nonliability of Lenders.  The relationship between the Borrower

on the one hand and the Lenders and the Administrative Agent on the other hand
shall be solely that of borrower and lender.  None of the Administrative Agent,
the Syndication Agent, the Documentation Agent, the Arranger or any Lender shall
have any fiduciary responsibilities to the Borrower.  None of the Administrative
Agent, the Syndication Agent, the Documentation Agent, the Arranger or any
Lender undertakes any responsibility to the Borrower to review or inform the
Borrower of any matter in connection with any phase of the Borrower's business
or operations.  The Borrower agrees that none of the Administrative Agent, the
Syndication Agent, the Documentation Agent, the Arranger or any Lender shall
have liability to the Borrower (whether sounding in tort, contract or otherwise)
for losses suffered by the Borrower in connection with, arising out of, or in
any way related to, the transactions contemplated and the relationship
established by the Loan Documents, or any act, omission or event occurring in
connection therewith, unless it is determined in a final non-appealable judgment
by a court of competent jurisdiction that such losses resulted from the gross
negligence or willful misconduct of the party from which recovery is sought.

          10.14  WAIVERS OF JURY TRIAL.  THE BORROWER, THE ADMINISTRATIVE AGENT
                 ---------------------

hereunder.

          10.16  Termination of Existing Credit Agreement.  Lenders which are
                 ----------------------------------------                    
parties to the Existing Credit Agreement (and which constitute "Majority
Lenders" under and as defined in the Existing Credit Agreement) hereby waive the
five Business Days' notice requirement set forth in Section 2.4 of the Existing
Credit Agreement for terminating the commitments under the Existing Credit

by applicable law, be prima facie evidence of the existence and amounts of the

notify each Lender thereof. If any such notice is given, the amount specified in
such notice shall be due and payable on the date specified therein, together

promptly notify each Lender thereof. If the last day of the then current
Interest Period with respect to C/D Rate Loans that are to be converted to
Eurodollar Loans is not a Business Day, such conversion shall be made on the
next succeeding Business Day, and during the period from such last day to such
succeeding Business Day such

continuation is not appropriate or (ii) after the date that is one month or 30
days prior to, respectively, the Termination Date and provided, further, that if
                                                      --------
the Borrower shall fail to give such notice or if such continuation is not
permitted such Loans shall be automatically converted to ABR Loans on the last
day of such then expiring Interest Period.

                  2.8 Minimum Amounts and Maximum Number of Tranches. All
                      ----------------------------------------------
borrowings, conversions and continuations of Loans hereunder and all selections
of Interest Periods hereunder shall be in such amounts and be made pursuant to
such elections so that, after giving effect thereto, the aggregate principal
amount of the Loans comprising (i) each Eurodollar Tranche shall be equal to
$5,000,000 or a whole multiple of $1,000,000 in excess thereof and (ii) each C/D
Rate Tranche shall be equal to $5,000,000 or a whole multiple of $1,000,000 in
excess thereof. In no event shall there be more than 16 Eurodollar Tranches or
16 C/D Rate Tranches outstanding at any time.

                  2.9 Interest Rates and Payment Dates. (a) Each Eurodollar Loan
                      --------------------------------
shall bear interest for each day during each Interest Period with respect
thereto at a rate per annum equal to the Eurodollar Rate determined for such day
plus the Applicable Margin.

                  (b) Each ABR Loan shall bear interest at a rate per annum
equal to the ABR plus the Applicable Margin.

                  (c) Each C/D Rate Loan shall bear interest for each day during
each Interest Period with respect thereto at a rate per annum equal to the C/D
Rate determined for such day plus the Applicable Margin.

                  (d) If all or a portion of (i) any principal of any Loan, (ii)
any interest payable thereon, (iii) any commitment fee, (iv) any other amount
payable hereunder shall not be paid when due (whether at the stated maturity, by
acceleration or otherwise) or (v) any other Event of Default shall have occurred
and be continuing, the principal of the Loans and any such overdue interest,
commitment fee or other amount shall bear interest at a rate per annum which is
(x) in the case of principal, the rate that would otherwise be applicable
thereto pursuant to the foregoing provisions of this subsection plus 2% or (y)
in the case of any such overdue interest,

                                       18
<PAGE>
 
commitment fee or other amount, the rate described in paragraph (b) of this
subsection plus 2%, in each case from the date of such non-payment until such
overdue principal, interest, commitment fee or other amount is paid in full (as
well after as before judgment).

     (e) Interest shall be payable in arrears on each Interest Payment Date and
on the Termination Date, provided that interest accruing pursuant to paragraph
                         --------
(d) of this subsection shall be payable from time to time on demand.

     2.10 Computation of Interest and Fees. (a) Commitment fees and, whenever it
          --------------------------------
is calculated on the basis of the Corporate Base Rate, interest shall be
calculated on the basis of a 365- (or 366-, as the case may be) day year for the
actual days elapsed; and, otherwise, interest shall be calculated on the basis
of a 360-day year for the actual days elapsed. The Administrative Agent shall as
soon as practicable notify the Borrower and the Lenders of each determination of
a Eurodollar Rate or of a C/D Rate. Any change in the interest rate on a Loan
resulting from a change in the ABR, the Eurocurrency Reserve Requirements, the
C/D Assessment Rate or the C/D Reserve Percentage shall become effective as of
the opening of business on the day on which such change becomes effective. The
Administrative Agent shall as soon as practicable notify the Borrower and the
Lenders of the effective date and the amount of each such change in interest
rate.

     (b) Each determination of an interest rate by the Administrative Agent
pursuant to any provision of this Agreement shall be conclusive and binding on
the Borrower and the Lenders in the absence of manifest error. The
Administrative Agent shall, at the request of the Borrower, deliver to the
Borrower a written statement showing the quotations used by the Administrative
Agent in determining any interest rate pursuant to subsection 2.9(a) or (c).

     (c) If any Reference Lender shall for any reason no longer have a
Commitment or any Loans, such Reference Lender shall thereupon cease to be a
Reference Lender, and if, as a result, there shall only be one Reference Lender
remaining, the Administrative Agent (after consultation with the Lenders and
with the approval of the Borrower) shall, by notice to the Borrower and the
Lenders, designate another Lender as a Reference Lender so that there shall at
all times be at least two Reference Lenders.

     (d) Each Reference Lender shall use its best efforts to furnish quotations
of rates to the Administrative Agent as contemplated hereby. If any of the
Reference Lenders shall be unable or shall otherwise fail to supply such rates
to the Administrative Agent upon its request, the rate of interest shall,
subject to the provisions of subsection 2.11, be determined on the basis of the
quotations of the remaining Reference Lenders or Reference Lender.

     2.11 Inability to Determine Interest Rate. If prior to the first day of 
          ------------------------------------
any Interest Period:

     (a) the Administrative Agent shall have determined (which determination
  shall be conclusive and binding upon the Borrower) that, by reason of
  circumstances affecting the relevant market, adequate and reasonable means do
  not exist for ascertaining the Eurodollar Rate or the C/D Rate for such
  Interest Period, or

                                       19
<PAGE>
 
          (b) the Administrative Agent shall have received notice from the
     Majority Lenders that the Eurodollar Rate or the C/D Rate determined or to
     be determined for such Interest Period will not adequately and fairly
     reflect the cost to such Lenders (as conclusively certified by such
     Lenders) of making or maintaining their affected Loans during such Interest
     Period,

the Administrative Agent shall give telecopy or telephonic notice thereof to the
Borrower and the Lenders as soon as practicable thereafter. If such notice is
given (x) any Eurodollar Loans or C/D Rate Loans, as the case may be, requested
to be made on the first day of such Interest Period shall be made as ABR Loans,
(y) any Loans that were to have been converted on the first day of such Interest
Period to Eurodollar Loans or C/D Rate Loans, as the case may be, shall be
converted to or continued as ABR Loans and (z) any outstanding Eurodollar Loans
or C/D Rate Loans, as the case may be, that were to have been continued as such
on such first day shall be converted on such day to ABR Loans. Until such notice
has been withdrawn by the Administrative Agent, no further Eurodollar Loans or
C/D Rate Loans, as the case may be, shall be made or continued as such, nor
shall the Borrower have the right to convert Loans to Eurodollar Loans or C/D
Rate Loans, as the case may be.

          2.12 Pro Rata Treatment and Payments. (a) Each borrowing by the
               -------------------------------
Borrower from the Lenders hereunder, each payment by the Borrower on account of
any commitment fee hereunder and any reduction of the Commitments of the Lenders
shall be made pro rata according to the respective Commitment Percentages of the
Lenders. Each payment (including each prepayment) by the Borrower on account of
principal of and interest on the Loans shall be made pro rata according to the
respective outstanding principal amounts of the Loans then held by the Lenders.
All payments (including prepayments) to be made by the Borrower hereunder,
whether on account of principal, interest, fees or otherwise, shall be made
without set off, counterclaim or other deduction and shall be made prior to
12:00 Noon, Chicago time, on the due date thereof to the Administrative Agent,
for the account of the Lenders, at the Administrative Agent's office specified
in subsection 10.2, in Dollars and in immediately available funds. The
Administrative Agent shall distribute such payments to the Lenders promptly upon
receipt in like funds as received. If any payment hereunder becomes due and
payable on a day other than a Business Day, such payment shall be extended to
the next succeeding Business Day, and, with respect to payments of principal,
interest thereon shall be payable at the then applicable rate during such
extension.

          (b) Unless the Administrative Agent shall have been notified in
writing by any Lender prior to a borrowing that such Lender will not make the
amount that would constitute its Commitment Percentage of such borrowing
available to the Administrative Agent, the Administrative Agent may assume that
such Lender is making such amount available to the Administrative Agent, and the
Administrative Agent may, in reliance upon such assumption, make available to
the Borrower a corresponding amount. If such amount is not made available to the
Administrative Agent by the required time on the Borrowing Date therefor, such
Lender shall pay to the Administrative Agent, on demand, such amount with
interest thereon at a rate equal to the daily average Federal Funds Effective
Rate for the period until such Lender makes such amount immediately available to
the Administrative Agent. A certificate of the Administrative Agent submitted to
any Lender with respect to any amounts owing under this subsection shall be
conclusive in the absence of manifest error. If such Lender's Commitment
Percentage of such borrowing is not made available to the Administrative Agent
by such Lender within three 

                                       20
<PAGE>
 
Business Days of such Borrowing Date, the Administrative Agent shall also be
entitled to recover such amount with interest thereon at the rate per annum
applicable to ABR Loans hereunder, on demand, from the Borrower.

          2.13 Illegality. Notwithstanding any other provision herein, if the
               ----------
adoption of or any change in any Requirement of Law or in the interpretation or
application thereof shall make it unlawful for any Lender to make or maintain
Eurodollar Loans as contemplated by this Agreement, (a) the commitment of such
Lender hereunder to make Eurodollar Loans, continue Eurodollar Loans as such and
convert Domestic Dollar Loans to Eurodollar Loans shall forthwith be cancelled
and (b) such Lender's Loans then outstanding as Eurodollar Loans, if any, shall
be converted automatically to ABR Loans on the respective last days of the then
current Interest Periods with respect to such Loans or within such earlier
period as required by law. If any such conversion of a Eurodollar Loan occurs on
a day which is not the last day of the then current Interest Period with respect
thereto, the Borrower shall pay to such Lender such amounts, if any, as may be
required pursuant to subsection 2.16.

          2.14 Requirements of Law. (a) If the adoption of or any change in any
               -------------------
Requirement of Law or in the interpretation or application thereof or compliance
by any Lender with any request or directive (whether or not having the force of
law) from any central bank or other Governmental Authority made subsequent to
the date hereof:

          (i) shall subject any Lender to any tax of any kind whatsoever with
     respect to this Agreement, any Note, any Letter of Credit, any Application
     or any Eurodollar Loan or C/D Rate Loan made by it, or change the basis of
     taxation of payments to such Lender in respect thereof (except for
     Non-Excluded Taxes covered by subsection 2.15 and changes in the rate of
     tax on the overall net income of such Lender);

          (ii) shall impose, modify or hold applicable any reserve, special
     deposit, compulsory loan or similar requirement against assets held by,
     deposits or other liabilities in or for the account of, advances, loans or
     other extensions of credit by, or any other acquisition of funds by, any
     office of such Lender which is not otherwise included in the determination
     of the Eurodollar Rate or the C/D Rate hereunder; or

          (iii) shall impose on such Lender any other condition;

and the result of any of the foregoing is to increase the cost to such Lender,
by an amount which such Lender deems to be material, of making, converting into,
continuing or maintaining Eurodollar Loans or C/D Rate Loans or issuing or
participating in Letters of Credit or to reduce any amount receivable hereunder
in respect thereof, then, in any such case, the Borrower shall pay such Lender
such additional amount or amounts as will compensate such Lender for such
increased cost or reduced amount receivable within 15 days following
notification of such increased cost or reduced amount receivable pursuant to
subsection 2.14(c) below, provided that such increased cost or reduced amount
                          --------
receivable shall be compensated only to the extent incurred during the 90 day
period prior to the notification of the Borrower by such Lender of such
increased cost or reduced amount receivable.

                                       21
<PAGE>
 
     (b) If any Lender shall have determined that the adoption of or any change
in any Requirement of Law regarding capital adequacy or in the interpretation or
application thereof or compliance by such Lender or any corporation controlling
such Lender with any request or directive regarding capital adequacy (whether or
not having the force of law) from any Governmental Authority made subsequent to
the date hereof shall have the effect of reducing the rate of return on such
Lender's or such corporation's capital as a consequence of its obligations
hereunder or under any Letter of Credit to a level below that which such Lender
or such corporation could have achieved but for such adoption, change or
compliance (taking into consideration such Lender's or such corporation's
policies with respect to capital adequacy) by an amount deemed by such Lender to
be material, then from time to time, the Borrower shall pay to such Lender such
additional amount or amounts as will compensate such Lender for such reduction
within 15 days following notification of such reduction pursuant to subsection
2.14(c) below, provided that such reduction shall be compensated only to the
               --------
extent incurred during the 90 day period prior to the notification of the
Borrower by such Lender of such reduction.

     (c) If any Lender becomes entitled to claim any additional amounts pursuant
to this subsection, it shall promptly notify the Borrower (with a copy to the
Administrative Agent) of the event by reason of which it has become so entitled.
A certificate as to any additional amounts payable pursuant to this subsection
submitted by such Lender to the Borrower (with a copy to the Administrative
Agent) shall be conclusive in the absence of manifest error. The agreements in
this subsection shall survive the termination of this Agreement and the payment
of the Loans and all other amounts payable hereunder.

     2.15 Taxes. (a) All payments made by the Borrower under this Agreement and
          -----
any Notes shall be made free and clear of, and without deduction or withholding
for or on account of, any present or future income, stamp or other taxes,
levies, imposts, duties, charges, fees, deductions or withholdings, now or
hereafter imposed, levied, collected, withheld or assessed by any Governmental
Authority, excluding net income taxes and franchise taxes (imposed in lieu of
net income taxes) imposed on the Administrative Agent or any Lender as a result
of a present or former connection between the Administrative Agent or such
Lender and the jurisdiction of the Governmental Authority imposing such tax or
any political subdivision or taxing authority thereof or therein (other than any
such connection arising solely from the Administrative Agent or such Lender
having executed, delivered or performed its obligations or received a payment
under, or enforced, this Agreement or any Note). If any such non-excluded taxes,
levies, imposts, duties, charges, fees deductions or withholdings ("Non-Excluded
                                                                    ------------
Taxes") are required to be withheld from any amounts payable to the
- -----
Administrative Agent or any Lender hereunder or under any Note, the amounts so
payable to the Administrative Agent or such Lender shall be increased to the
extent necessary to yield to the Administrative Agent or such Lender (after
payment of all Non-Excluded Taxes) interest or any such other amounts payable
hereunder at the rates or in the amounts specified in this Agreement, provided,
                                                                       -------
however, that the Borrower shall not be required to increase any such amounts
- -------
payable to any Lender that is not organized under the laws of the United States
of America or a state thereof if such Lender fails to comply with the
requirements of paragraph (b) of this subsection. Whenever any Non-Excluded
Taxes are payable by the Borrower, as promptly as possible thereafter the
Borrower shall send to the Administrative Agent for its own account or for the
account of such Lender, as the case may be, a certified copy of an original
official receipt received by the Borrower showing payment thereof. If the
Borrower fails to pay any Non-Excluded Taxes when due to the appropriate taxing

                                       22
<PAGE>
 
authority or fails to remit to the Administrative Agent the required receipts or
other required documentary evidence, the Borrower shall indemnify the
Administrative Agent and the Lenders for any incremental taxes, interest or
penalties that may become payable by the Administrative Agent or any Lender as a
result of any such failure. The agreements in this subsection shall survive the
termination of this Agreement and the payment of the Loans and all other amounts
payable hereunder.

          (b) Each Lender that is not incorporated under the laws of the United
States of America or a state thereof shall:

          (i) deliver to the Borrower and the Administrative Agent (A) two duly
     completed copies of United States Internal Revenue Service Form 1001 or
     4224, or successor applicable form, as the case may be, and (B) an Internal
     Revenue Service Form W-8 or W-9, or successor applicable form, as the case
     may be;

          (ii) deliver to the Borrower and the Administrative Agent two further
     copies of any such form or certification on or before the date that any
     such form or certification expires or becomes obsolete and after the
     occurrence of any event requiring a change in the most recent form
     previously delivered by it to the Borrower; and

          (iii) obtain such extensions of time for filing and complete such
     forms or certifications as may reasonably be requested by the Borrower or
     the Administrative Agent;

unless in any such case an event (including, without limitation, any change in
treaty, law or regulation) has occurred prior to the date on which any such
delivery would otherwise be required which renders all such forms inapplicable
or which would prevent such Lender from duly completing and delivering any such
form with respect to it and such Lender so advises the Borrower and the
Administrative Agent. Such Lender shall certify (i) in the case of a Form 1001
or 4224, that it is entitled to receive payments under this Agreement without
deduction or withholding of any United States federal income taxes and (ii) in
the case of a Form W-8 or W-9, that it is entitled to an exemption from United
States backup withholding tax. Each Person that shall become a Lender or a
Participant pursuant to subsection 9.6 shall, upon the effectiveness of the
related transfer, be required to provide all of the forms and statements
required pursuant to this subsection, provided that in the case of a Participant
such Participant shall furnish all such required forms and statements to the
Lender from which the related participation shall have been purchased.

     2.16 Indemnity. The Borrower agrees to indemnify each Lender and to hold
          ---------
each Lender harmless from any loss or expense which such Lender may sustain or
incur as a consequence of (a) default by the Borrower in making a borrowing of,
conversion into or continuation of Eurodollar Loans or C/D Rate Loans after the
Borrower has given a notice requesting the same in accordance with the
provisions of this Agreement, (b) default by the Borrower in making any
prepayment after the Borrower has given a notice thereof in accordance with the
provisions of this Agreement or (c) the making of a prepayment of Eurodollar
Loans or C/D Rate Loans on a day which is not the last day of an Interest Period
with respect thereto. Such indemnification may include an amount equal to the
excess, if any, of (i) the amount of 

                                       23
<PAGE>
 
interest which would have accrued on the amount so prepaid, or not so borrowed,
converted or continued, for the period from the date of such prepayment or of
such failure to borrow, convert or continue to the last day of such Interest
Period (or, in the case of a failure to borrow, convert or continue, the
Interest Period that would have commenced on the date of such failure) in each
case at the applicable rate of interest for such Loans provided for herein
(excluding, however, the Applicable Margin included therein, if any) over (ii)
the amount of interest (as reasonably determined by such Lender) which would
have accrued to such Bank on such amount by placing such amount on deposit for a
comparable period with leading banks in the interbank eurodollar market. This
covenant shall survive the termination of this Agreement and the payment of the
Loans and all other amounts payable hereunder.

     2.17 Change of Lending Office. Each Lender agrees that if it makes any
          ------------------------
demand for payment under subsection 2.14 or 2.15(a), or if any adoption or
change of the type described in subsection 2.13 shall occur with respect to it,
it will use reasonable efforts (consistent with its internal policy and legal
and regulatory restrictions and so long as such efforts would not be
disadvantageous to it, as determined in its sole discretion) to designate a
different lending office if the making of such a designation would reduce or
obviate the need for the Borrower to make payments under subsection 2.14 or
2.15(a), or would eliminate or reduce the effect of any adoption or change
described in subsection 2.13.

     2.18 Extension of Maturity Date. (a) Not less than 60 days and not more
          --------------------------
than 90 days prior to the date that is one year prior to the Termination Date
then in effect, provided that no Event of Default shall have occurred and be
continuing, the Borrower may request an extension of such Termination Date by
submitting to the Administrative Agent an Extension Request containing the
information in respect of such extension specified in Exhibit B, which the
Administrative Agent shall promptly furnish to each Lender. Each Lender shall,
not less than 30 days and not more than 45 days prior to the date that is one
year prior to the Termination Date then in effect, notify the Borrower and the
Administrative Agent of its election to extend or not extend the Termination
Date as requested in such Extension Request. Notwithstanding any provision of
this Agreement to the contrary, any notice by any Lender of its willingness to
extend the Termination Date shall be revocable by such Lender in its sole and
absolute discretion at any time prior to the date which is 30 days prior to the
date that is one year prior to the Termination Date then in effect. If the then
Majority Lenders shall approve in writing the extension of the Termination Date
requested in such Extension Request, the Termination Date shall automatically
and without any further action by any Person be extended for the period
specified in such Extension Request; provided that (i) each extension pursuant
                                     --------
to this subsection shall be for a maximum of one year and (ii) the Commitment of
any Lender that does not consent in writing to such extension not less than 30
days and not more than 45 days prior to the date that is one year prior to the
Termination Date then in effect (an "Objecting Lender") shall, unless earlier
                                     ----------------
terminated in accordance with this Agreement, expire on the Termination Date in
effect on the date of such Extension Request (such Termination Date, if any,
referred to as the "Commitment Expiration Date" with respect to such Objecting
                    --------------------------
Lender). If, not less than 30 days and not more than 45 days prior to the date
that is one year prior to the Termination Date then in effect, the then Majority
Lenders shall not approve in writing the extension of the Termination Date
requested in an Extension Request, the Termination Date shall not be extended
pursuant to such Extension Request. The Administrative Agent shall promptly
notify (y) the Lenders and the 

                                       24
<PAGE>
 
Borrower of any extension of the Termination Date pursuant to this subsection
and (z) the Borrower and each other Lender of any Lender which becomes an
Objecting Lender.

     (b) Loans owing to any Objecting Lender on the Commitment Expiration Date
with respect to such Lender shall be repaid in full on or before such Commitment
Expiration Date.

     (c) The Borrower may, at its sole expense and effort, upon notice to any
Objecting Lender or any Lender who is an "Objecting Lender" as defined in the
Other Credit Agreement (an "Other Objecting Lender") and the Administrative
                            ----------------------
Agent, require such Objecting Lender or Other Objecting Lender, as the case may
be, to assign and delegate, without recourse (in accordance with and subject to
the restrictions contained in subsection 10.6), all its interests, rights and
obligations under this Agreement to an assignee that shall assume such
obligations (which assignee may be another Lender, if a Lender accepts such
assignment); provided that (i) the Borrower shall have received the prior
             --------
written consent of the Administrative Agent and the Issuing Banks (unless such
Objecting Lender or Other Objecting Lender is the Administrative Agent or an
Issuing Bank, in which case its consent shall not be required), which consents
shall not unreasonably be withheld, (ii) such Objecting Lender or Other
Objecting Lender, as the case may be, shall have received payment of an amount
equal to the outstanding principal of its Loans and participations in Letter of
Credit disbursements, accrued interest thereon, accrued fees and all other
amounts payable to it hereunder, from the assignee (to the extent of such
outstanding principal and accrued interest and fees) or the Borrower (in the
case of all other amounts).

     (d) For a period of 90 days following any extension of the Termination Date
pursuant to this subsection 2.18, the Borrower may, at its sole expense and
effort, upon notice to the Administrative Agent, cause additional banks or other
financial institutions to become parties hereto as Lenders to replace the
Commitments of Objecting Lenders no longer parties hereto, provided that the
                                                           --------
aggregate Commitments shall not exceed the aggregate Commitments existing prior
to such extension. Such additional banks or other financial institutions shall
be subject to the approval of the Administrative Agent and the Issuing Banks
(the consent of which will not be unreasonably withheld) and shall become
parties hereto by executing such supplements hereto as shall be satisfactory to
the Borrower and the Administrative Agent. Upon any such bank or other financial
institution so becoming a Lender the Borrower will effect such borrowings and
prepayments as are necessary to cause all then outstanding Loans to be held
ratably by all the Lenders.

     2.19 Telephonic Notices. The Borrower hereby authorizes the Lenders and the
          ------------------
Administrative Agent to extend, convert or continue Loans, effect selections of
Types of Loans and to transfer funds based on telephonic notices made by any
person or persons the Administrative Agent or any Lender in good faith believes
to be a Responsible Officer or manager of corporate markets acting on behalf of
the Borrower. The Borrower agrees to deliver promptly to the Administrative
Agent a written confirmation, if such confirmation is requested by the
Administrative Agent or any Lender, of each telephonic notice signed by a
Responsible Officer. If the written confirmation differs in any material respect
from the action taken by the Administrative Agent and the Lenders, the records
of the Administrative Agent and the Lenders shall govern absent manifest error.

                         SECTION 3. LETTERS OF CREDIT

     3.1 L/C Commitment.
         --------------

     (a) Subject to the terms and conditions hereof, the Issuing Bank, in
reliance on the agreements of the other Lenders set forth in subsection 3.4(a),
agrees to issue letters of credit ("Letters of Credit") for the account of the
                                    -----------------
Borrower on any Business Day during the Commitment Period in such form as may be
approved from time to time by the Issuing Bank; provided that the Issuing Bank
                                                --------
shall have no obligation to issue any Letter of Credit if, after giving effect
to such issuance, (i) the L/C Obligations would exceed the L/C Commitment or
(ii) the Available Commitment of any Lender would be less than zero.

     (b Each Letter of Credit shall:

     (i be denominated in Dollars and shall be a standby letter of credit
   issued to support obligations of the Borrower or any Subsidiary, contingent
   or otherwise, and

     (ii expire no later than the earlier of (A) the date that is two years
   from the date of issue of such Letter of Credit and (B) the date which is
   ten days prior to the Termination Date.

     (c Anything in this Agreement to the contrary notwithstanding, the Existing
L/Cs shall be deemed Letters of Credit issued hereunder on the Closing Date,
unless such Existing L/Cs shall have been terminated prior to the Closing Date.

     (d Each Letter of Credit shall be subject to the Uniform Customs and, to
the extent not inconsistent therewith, the laws of the State of New York.

     (e) The Issuing Bank shall not at any time be obligated to issue any Letter
of Credit hereunder if such issuance would conflict with, or cause the Issuing
Bank or any L/C Participant to exceed any limits imposed by, any applicable
Requirement of Law.

     3.2 Procedure for Issuance of Letters of Credit.
         -------------------------------------------

     The Borrower may from time to time request that the Issuing Bank issue a
Letter of Credit by delivering to the Issuing Bank at its address for notices
specified herein an Application therefor, completed to the satisfaction of the
Issuing Bank, and such other certificates, documents and other papers and
information as the Issuing Bank may request. Upon receipt of any Application,
the Issuing Bank will process such Application and the certificates, documents
and other papers and information delivered to it in connection therewith in
accordance with its customary procedures and shall promptly issue the Letter of
Credit requested thereby (but in no event shall the Issuing Bank be required to
issue any Letter of Credit earlier than three Business Days after its receipt of
the Application therefor and all such other certificates, documents and other
papers and information relating thereto) by issuing the original of such Letter
of Credit to the beneficiary thereof or as otherwise may be agreed by the
Issuing Bank and the Borrower. The Issuing Bank shall furnish a copy of such
Letter of Credit to the Borrower promptly following the issuance thereof.

     3.3 Fees and Other Charges. (a) The Borrower will pay a fee on all
         ----------------------
outstanding Letters of Credit at a per annum rate equal to the Applicable Margin
then in effect with respect to Eurodollar Loans hereunder which fee shall be
payable to the Administrative Agent, to be shared ratably among the L/C
Participants and to be payable quarterly in arrears on each L/C Fee Payment Date
after the issuance date. In addition, the Borrower shall pay to each Issuing
Bank for its own account an issuing fee with respect to each Letter of Credit
issued by such Issuing Bank as set forth in that certain letter agreement among
the Borrower, CIBC, First Chicago and First Chicago Capital Markets, Inc. dated
November 17, 1997, or as otherwise agreed from time to time, on all outstanding
letters of credit, payable quarterly in arrears on each L/C Fee Payment Date
after the issuance date.

     (b In addition to the foregoing fees and commissions, the Borrower shall
pay or reimburse the Issuing Bank for such normal and customary costs and
expenses as are incurred or charged by the Issuing Bank in issuing, negotiating,
effecting payment under, amending or otherwise administering any Letter of
Credit.

     3.4 L/C Participations.
         ------------------

     (a The Issuing Bank irrevocably agrees to grant and hereby grants to each
L/C Participant, and, to induce the Issuing Bank to issue Letters of Credit
hereunder, each L/C Participant irrevocably agrees to accept and purchase and
hereby accepts and purchases from the Issuing Bank, on the terms and conditions
hereinafter stated, for such L/C Participant's own account and risk an undivided
interest equal to such L/C Participant's Commitment Percentage in the Issuing
Bank's obligations and rights under each Letter of Credit issued hereunder and
the amount of each draft paid by the Issuing Bank thereunder. Each L/C
Participant unconditionally and irrevocably agrees with the Issuing Bank that,
if a draft is paid under any Letter of Credit for which the Issuing Bank is not
reimbursed in full by the Borrower in accordance with the terms of this
Agreement, such L/C Participant shall pay to the Issuing Bank upon demand at the
Issuing Bank's address for notices specified herein an amount equal to such L/C
Participant's Commitment Percentage of the amount of such draft, or any part
thereof, which is not so reimbursed. Each L/C Participant acknowledges and
agrees that its obligation to acquire 

                                       27
<PAGE>
 
participations pursuant to this paragraph in respect of Letters of Credit is
absolute and unconditional and shall not be affected by any circumstances
whatsoever, including the occurrence and continuance of a Default or an Event of
Default or the termination of the Commitments, and that each such payment shall
be made without any offset, abatement, withholding or reduction whatsoever.

     (b If any amount required to be paid by any L/C Participant to the Issuing
Bank pursuant to subsection 3.4(a) in respect of any unreimbursed portion of any
payment made by the Issuing Bank under any Letter of Credit is not paid to the
Issuing Bank when due but is paid to the Issuing Bank within three Business Days
after the date such payment is due, such L/C Participant shall pay to the
Issuing Bank on demand an amount equal to the product of (i) such amount, times
(ii) the daily average Federal funds rate, as quoted by the Issuing Bank, during
the period from and including the date such payment is required to the date on
which such payment is immediately available to the Issuing Bank, times (iii) a
fraction the numerator of which is the number of days that elapse during such
period and the denominator of which is 360. If any such amount required to be
paid by any L/C Participant pursuant to subsection 3.4(a) is not in fact made
available to the Issuing Bank by such L/C Participant within three Business Days
after the date such payment is due, the Issuing Bank shall be entitled to
recover from such L/C Participant, on demand, such amount with interest thereon
calculated from such due date at the rate per annum applicable to ABR Loans
hereunder. A certificate of the Issuing Bank submitted to any L/C Participant
with respect to any amounts owing under this subsection shall be conclusive in
the absence of manifest error.

     (c Whenever, at any time after the Issuing Bank has made payment under any
Letter of Credit and has received from any L/C Participant its pro rata share of
such payment in accordance with subsection 3.4(a), the Issuing Bank receives any
payment related to such Letter of Credit (whether directly from the Borrower or
otherwise, including proceeds of collateral applied thereto by the Issuing
Bank), or any payment of interest on account thereof, the Issuing Bank will
distribute to such L/C Participant its pro rata share thereof; provided,
                                                               --------
however, that in the event that any such payment received by the Issuing Bank
- -------
shall be required to be returned by the Issuing Bank, such L/C Participant shall
return to the Issuing Bank the portion thereof previously distributed by the
Issuing Bank to it.

     3.5 Reimbursement Obligation of the Borrower.
         ----------------------------------------

     (a The Borrower agrees to reimburse the Issuing Bank on each date on which
the Issuing Bank notifies the Borrower of the date and amount of a draft
presented under any Letter of Credit and paid by the Issuing Bank for the amount
of (i) such draft so paid and (ii) any taxes, fees, charges or other costs or
expenses incurred by the Issuing Bank in connection with such payment. Each such
payment shall be made to the Issuing Bank at its address for notices specified
herein in Dollars and in immediately available funds.

     (b Interest shall be payable on any and all amounts remaining unpaid by the
Borrower under this subsection from the date such amounts become payable
(whether at stated maturity, by acceleration or otherwise) until payment in full
at the rate which would be payable on any outstanding ABR Loans which were then
overdue.

                                       28
<PAGE>
 
     (c Each drawing under any Letter of Credit shall constitute a request by
the Borrower to the Administrative Agent for a borrowing pursuant to subsection
2.2 of ABR Loans in the amount of such drawing. The Borrowing Date with respect
to such borrowing shall be the date of such drawing.

     3.6 Obligations Absolute.
         --------------------

     (a The Borrower's obligations under this Section 3 shall be absolute and
unconditional under any and all circumstances and irrespective of any set-off,
counterclaim or defense to payment which the Borrower may have or have had
against the Issuing Bank or any beneficiary of a Letter of Credit.

     (b The Borrower also agrees with the Issuing Bank that the Issuing Bank
shall not be responsible for, and the Borrower's Reimbursement Obligations under
subsection 3.5(a) shall not be affected by, among other things, (i) the validity
or genuineness of documents or of any endorsements thereon, even though such
documents shall in fact prove to be invalid, fraudulent or forged (subject,
however, to the provisions of subsection 3.6(d)), or (ii) any dispute between or
among the Borrower and any beneficiary of any Letter of Credit or any other
party to which such Letter of Credit may be transferred or (iii) any claims
whatsoever of the Borrower against any beneficiary of such Letter of Credit or
any such transferee.

     (c The Issuing Bank shall not be liable for any error, omission,
interruption or delay in transmission, dispatch or delivery of any message or
advice, however transmitted, in connection with any Letter of Credit, except for
errors or omissions caused by the Issuing Bank's gross negligence or willful
misconduct.

     (d The Borrower agrees that any action taken or omitted by the Issuing Bank
under or in connection with any Letter of Credit or the related drafts or
documents, if done in the absence of gross negligence or willful misconduct and
in accordance with the standards of care specified in the Uniform Commercial
Code of the State of New York, shall be binding on the Borrower and shall not
result in any liability of the Issuing Bank to the Borrower.

     3.7 Letter of Credit Payments.
         -------------------------

     If any draft shall be presented for payment under any Letter of Credit, the
Issuing Bank shall promptly notify the Borrower of the date and amount thereof.
The responsibility of the Issuing Bank to the Borrower in connection with any
draft presented for payment under any Letter of Credit shall, in addition to any
payment obligation expressly provided for in such Letter of Credit, be limited
to determining that the documents (including each draft) delivered under such
Letter of Credit in connection with such presentment are in conformity with such
Letter of Credit.

     3.8 Application.
         -----------

     To the extent that any provision of any Application related to any Letter
of Credit is inconsistent with the provisions of this Section 3, the provisions
of this Section 3 shall apply.

                   SECTION 4. REPRESENTATIONS AND WARRANTIES

     To induce the Lenders to enter into this Agreement and to make the Loans
and issue or participate in the Letters of Credit, the Borrower hereby
represents and warrants to the Administrative Agent and each Lender that:

     4.1 Financial Condition. (a)(i) The consolidated balance sheet of AEI and
         -------------------
its consolidated Subsidiaries as at December 31, 1996 and the related
consolidated statements of income and of cash flows for the fiscal year ended on
such date, reported on by Deloitte & Touche LLP, copies of which have heretofore
been furnished to each Lender, are complete and correct and present fairly the
consolidated financial condition of AEI and its consolidated Subsidiaries as at
such date, and the consolidated results of their operations and their
consolidated cash flows for the fiscal year then ended. The unaudited
consolidated balance sheet of AEI and its consolidated Subsidiaries as at
September 30, 1997 and the related unaudited consolidated statements of income
and of cash flows for the nine-month period ended on such date, certified by a
Responsible Officer, copies of which have heretofore been furnished to each
Lender, are complete and correct and present fairly the consolidated financial
condition of AEI and its consolidated Subsidiaries as at such date, and the
consolidated results of their operations and their consolidated cash flows for
the nine-month period then ended (subject to normal year-end audit adjustments).
All such financial statements, including the related schedules and notes
thereto, have been prepared in accordance with GAAP applied consistently
throughout the periods involved (except as approved by such accountants or
Responsible Officer, as the case may be, and as disclosed therein). Neither AEI
nor any of its consolidated Subsidiaries had, at the date of the most recent
balance sheet referred to above, any material Guarantee Obligation, contingent
liability or liability for taxes, or any long-term lease or unusual forward or
long-term commitment, including, without limitation, any interest rate or
foreign currency swap or exchange transaction, which is not reflected in the
foregoing statements or in the notes thereto. During the period from December
31, 1996 to and including the date hereof there has been no sale, transfer or
other disposition by AEI or any of its consolidated Subsidiaries of any material
part of its business or property and no purchase or other acquisition of any
business or property (including any capital stock of any other Person) material
in relation to the consolidated financial condition of AEI and its consolidated
Subsidiaries at December 31, 1996. (ii) The consolidated balance sheet of
Delmarva and its consolidated Subsidiaries as at December 31, 1996 and the
related consolidated statements of income and of cash flows for the fiscal year
ended on such date, reported on by Coopers & Lybrand L.L.P., copies of which
have heretofore been furnished to each Lender, are complete and correct and
present fairly the consolidated financial condition of Delmarva and its
consolidated Subsidiaries as at such date, and the consolidated results of their
operations and their consolidated cash flows for the fiscal year then ended. The
unaudited consolidated balance sheet of Delmarva and its consolidated
Subsidiaries as at September 30, 1997 and the related unaudited consolidated
statements of income and of cash flows for the nine-month period ended on such
date, certified by a Responsible Officer, copies of which have heretofore been
furnished to each Lender, are complete and correct and present fairly the
consolidated financial condition of Delmarva and its consolidated Subsidiaries
as at such date, and the consolidated results of their operations and their
consolidated cash flows for the nine-month period then ended (subject to normal
year-end audit adjustments). All such financial statements, including the
related schedules and notes thereto, have been prepared in accordance with GAAP
applied consistently throughout the periods involved (except as approved by such

                                       30
<PAGE>
 
accountants or Responsible Officer, as the case may be, and as disclosed
therein). Neither Delmarva nor any of its consolidated Subsidiaries had, at the
date of the most recent balance sheet referred to above, any material Guarantee
Obligation, contingent liability or liability for taxes, or any long-term lease
or unusual forward or long-term commitment, including, without limitation, any
interest rate or foreign currency swap or exchange transaction, which is not
reflected in the foregoing statements or in the notes thereto. During the period
from December 31, 1996 to and including the date hereof there has been no sale,
transfer or other disposition by Delmarva or any of its consolidated
Subsidiaries of any material part of its business or property and no purchase or
other acquisition of any business or property (including any capital stock of
any other Person) material in relation to the consolidated financial condition
of Delmarva and its consolidated Subsidiaries at December 31, 1996.

     (b The unaudited pro forma balance sheets of the Borrower and its
                      ---------
consolidated Subsidiaries as at September 30, 1997, certified by a Responsible
Officer of the Borrower (collectively, the "Pro Forma Balance Sheet"), copies of
                                            ----------------------- 
which have been furnished to each Lender, is the unaudited consolidated balance
sheet of the Borrower and its consolidated Subsidiaries, adjusted to give effect
(as if such events had occurred on such date) to the Merger and the incurrence
of the Loans hereunder. The Pro Forma Balance Sheet, together with the notes
thereto, was prepared in accordance with GAAP and reflects on a pro forma basis
the financial position of the Borrower and its consolidated Subsidiaries as at
January 1, 1998, as adjusted as described above, assuming that the events
specified in the preceding sentence had actually occurred at such date.

     (c The projections, certified by a Responsible Officer of the Borrower, by
the Borrower of the operating budget and cash flow budget of the Borrower and
its Subsidiaries for the five fiscal years following the consummation of the
Merger, copies of which have heretofore been furnished to each Lender
(collectively, the "Five-Year Projections"), have been prepared on the basis of
                    ---------------------
sound financial planning practice and the Borrower has no reason to believe they
are incorrect or misleading in any material respect.

     4.2 No Change. Since September 30, 1997 there has been no development or
         ---------
event which has had or could reasonably be expected to have a Material Adverse
Effect.

     4.3 Corporate Existence; Compliance with Law. Each of the Borrower and its
         ----------------------------------------
Subsidiaries (a) is duly organized, validly existing and in good standing under
the laws of the jurisdiction of its organization, (b) has the corporate power
and authority, and the legal right, to own and operate its property, to lease
the property it operates as lessee and to conduct the business in which it is
currently engaged, (c) is duly qualified as a foreign corporation and in good
standing under the laws of each jurisdiction where its ownership, lease or
operation of property or the conduct of its business requires such qualification
and (d) is in compliance with all Requirements of Law, except to the extent that
the failure to comply with clauses (a) through (d) above would not, in the
aggregate, reasonably be expected to have a Material Adverse Effect.

     4.4 Corporate Power; Authorization; Enforceable Obligations. (a) The
         -------------------------------------------------------
Borrower has the corporate power and authority, and the legal right, to make,
deliver and perform this Agreement and each other Loan Document and to borrow
hereunder and has taken all necessary corporate action to authorize the
borrowings on the terms and conditions of this Agreement and

                                       31
<PAGE>
 
each other Loan Document and to authorize the execution, delivery and
performance of this Agreement, the Notes and the Applications and each other
Loan Document to which it is a party.

     (b Except for consents, authorizations, approvals, notices and filings
described on Schedule 4.4, all of which have been obtained, made or waived, no
consent or authorization of, approval by, notice to, filing with or other act by
or in respect of, any Governmental Authority (including, without limitation, the
United States Securities and Exchange Commission under the Public Utility
Holding Company Act of 1935, as amended) or any other Person is required in
connection with the borrowings hereunder or with the execution, delivery,
performance, validity or enforceability of this Agreement or any other Loan
Document.

     (c This Agreement has been, and each other Loan Document will be, duly
executed and delivered on behalf of the Borrower.

     (d This Agreement constitutes, and each other Loan Document when executed
and delivered will constitute, a legal, valid and binding obligation of the
Borrower enforceable against the Borrower in accordance with its terms, except
as affected by bankruptcy, insolvency, fraudulent conveyance, reorganization,
moratorium and other similar laws relating to the enforcement of creditors'
rights generally and general equitable principles (whether considered in a
proceeding in equity or at law).

     4.5 No Legal Bar. The execution, delivery and performance of this
         ------------
Agreement, any Applications and any Notes, the borrowings hereunder and the use
of the proceeds thereof will not violate any Requirement of Law or material
Contractual Obligation of the Borrower or of any of its Subsidiaries and will
not result in, or require, the creation or imposition of any Lien on any of its
or their respective properties or revenues pursuant to any such Requirement of
Law or Contractual Obligation.

     4.6 No Material Litigation. Except as heretofore disclosed to the Lenders
         ----------------------
by the Borrower (a) in its financial statements referred to in subsection 4.1 or
(b) in quarterly or other periodic reports filed with the United States
Securities and Exchange Commission copies of which have been delivered to the
Lenders prior to the date hereof, no litigation, investigation or proceeding of
or before any arbitrator or Governmental Authority is pending or, to the
knowledge of the Borrower, threatened by or against the Borrower or any of its
Subsidiaries or against any of its or their respective properties or revenues
which could reasonably be expected to have a Material Adverse Effect.

     4.7 Ownership of Property; Liens. Each of the Borrower and its Subsidiaries
         ----------------------------
has good record and marketable title in fee simple to, or a valid leasehold
interest in, all its real property, and good title to, or a valid leasehold
interest in, all its other property, except to the extent that the failure to
have such title or leasehold interest could not, in the aggregate, reasonably be
expected to have a Material Adverse Effect, and none of such property is subject
to any Lien except as permitted by subsection 7.2.

     4.8 Taxes. Each of the Borrower and its Subsidiaries has filed or caused to
         -----
be filed all tax returns which, to the knowledge of the Borrower, are required
to be filed and has paid all taxes shown to be due and payable on said returns
or on any assessments made against it

                                       32
<PAGE>
 
or any of its property and all other taxes, fees or other charges imposed on it
or any of its property by any Governmental Authority (other than any the amount
or validity of which are currently being contested in good faith by appropriate
proceedings and with respect to which reserves in conformity with GAAP have been
provided on the books of the Borrower or its Subsidiaries, as the case may be),
except to the extent that the failure to file such tax returns or pay such
taxes, fees and other charges would not, in the aggregate, reasonably be
expected to have a Material Adverse Effect.

     4.9 Federal Regulations. No part of the proceeds of any Loans will be used
         -------------------
in any manner that would result in a violation of Regulation G or Regulation U
of the Board of Governors of the Federal Reserve System as now and from time to
time hereafter in effect.

     4.10 ERISA. Neither a Reportable Event nor an "accumulated funding
          -----
deficiency" (within the meaning of Section 412 of the Code or Section 302 of
ERISA) has occurred during the five-year period prior to the date on which this
representation is made or deemed made with respect to any Plan, and each Plan
has complied in all material respects with the applicable provisions of ERISA
and the Code. No termination of a Single Employer Plan has occurred, and no Lien
in favor of the PBGC or a Plan has arisen, during such five-year period. The
present value of all accrued benefits under each Single Employer Plan (based on
those assumptions used to fund such Plans) did not, as of the last annual
valuation date prior to the date on which this representation is made or deemed
made, exceed the value of the assets of such Plan allocable to such accrued
benefits. Neither the Borrower nor any Commonly Controlled Entity has had a
complete or partial withdrawal from any Multiemployer Plan, and neither the
Borrower nor any Commonly Controlled Entity would become subject to any
liability under ERISA if the Borrower or any such Commonly Controlled Entity
were to withdraw completely from all Multiemployer Plans as of the valuation
date most closely preceding the date on which this representation is made or
deemed made. No such Multiemployer Plan is in Reorganization or Insolvent.

     4.11 Investment Company Act. The Borrower is not an "investment company",
          ----------------------
or a company "controlled" by an "investment company", within the meaning of the
Investment Company Act of 1940, as amended.

     4.12 Purpose of Loans. The proceeds of the Loans shall be used by the
          ----------------
Borrower for general corporate purposes.

     4.13 Environmental Matters. In the ordinary course of its business, the
          ---------------------
officers of the Borrower consider the effect of Environmental Laws on the
business of the Borrower and its Subsidiaries, in the course of which they
identify and evaluate potential risks and liabilities accruing to the Borrower
due to Environmental Laws. On the basis of this consideration, the Borrower has
reasonably concluded that Environmental Laws cannot reasonably be expected to
have a Material Adverse Effect. Neither the Borrower nor any Subsidiary has
received any notice to the effect that its operations are not in material
compliance with any of the requirements of applicable Environmental Laws or are
the subject of any federal or state investigation evaluating whether any
remedial action is needed to respond to a release of any toxic or hazardous
waste or substance into the environment, which non-compliance or remedial action
could reasonably be expected to have a Material Adverse Effect.

     Borrower on the Closing Date and each other director, if such other

     Borrower is recommended by a majority of the then Continuing Directors;

then, and in any such event, (A) if such event is an Event of Default specified
in clause (i) or (ii) of paragraph (f) of this Section with respect to the
Borrower, automatically the Commitments shall immediately terminate and the
Loans hereunder (with accrued interest thereon) and all other amounts owing
under this Agreement (including, without limitation, all amounts of L/C
Obligations, whether or not the beneficiaries of the then outstanding Letters of
Credit shall have presented the documents required thereunder) and any Notes
shall immediately become due and payable, and (B) if such event is any other
Event of Default, either or both of the following actions may be taken: (i) with
the consent of the Majority Lenders, the Administrative Agent may, or upon the
request of the Majority Lenders, the Administrative Agent shall, by notice to
the Borrower declare the Commitments to be terminated forthwith, whereupon the
Commitments shall immediately terminate; and (ii) with the consent of the
Majority Lenders, the Administrative Agent may, or upon the request of the
Majority Lenders, the Administrative Agent shall, by notice of default to the

the aggregate then undrawn and unexpired amount of such Letters of Credit. The
Borrower hereby grants to the Administrative Agent, for the benefit of the
Issuing Bank and the L/C Participants, a security interest in such cash
collateral to secure all obligations of the Borrower under this Agreement and
the other Loan Documents. Amounts held in such cash collateral account shall be
applied by the Administrative Agent to the payment of drafts drawn under such
Letters of Credit, and the unused portion thereof after all such Letters of
Credit shall have expired or been fully drawn upon, if any, shall be applied to
repay other obligations of the Borrower hereunder and under any Notes. After all
such Letters of Credit shall have expired or been fully drawn upon, all
Reimbursement Obligations shall have been satisfied and all other obligations of
the Borrower hereunder and under any Notes shall have been paid in full, the
balance, if any, in such cash collateral account shall be returned to the
Borrower. The Borrower shall execute and deliver to the Administrative Agent,
for the account of the Issuing Bank and

Administrative Agent may request to evidence the creation and perfection of the
within security interest in such cash collateral account.

          Except as expressly provided above in this Section, presentment,
demand, protest and all other notices of any kind are hereby expressly waived.


                              SECTION 9. THE AGENTS

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

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

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

             9.4 No Responsibility for Loans, Recitals, etc. Neither the
                 ------------------------------------------
Administrative Agent nor any of its directors, officers, agents or employees
shall be responsible for or have any duty to ascertain, inquire into, or verify
(a) any statement, warranty or representation made in connection 

                                       45
<PAGE>
 
with any Loan Document or any borrowing hereunder; (b) the performance or
observance of any of the covenants or agreements of any obligor under any Loan
Document, including, without limitation, any agreement by an obligor to furnish
information directly to each Lender; (c) the satisfaction of any condition
specified in Section 5, except receipt of items required to be delivered solely
to the Administrative Agent; (d) the existence or possible existence of any
Default or Event of Default; (e) the validity, enforceability, effectiveness,
sufficiency or genuineness of any Loan Document or any other instrument or
writing furnished in connection therewith (except as may relate to the execution
by the Administrative Agent of any Loan Document); (f) the value, sufficiency,
creation, perfection or priority of any Lien in any collateral security; or (g)
the financial condition of the Borrower or any guarantor of any of the
Obligations or of any of the Borrower's or any such guarantor's respective
Subsidiaries. The Administrative Agent shall have no duty to disclose to the
Lenders information that is not required to be furnished by the Borrower to the
Administrative Agent at such time, but is voluntarily furnished by the Borrower
to the Administrative Agent (either in its capacity as Administrative Agent or
in its individual capacity).

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

             9.6 Employment of Administrative Agents and Counsel. The
                 -----------------------------------------------
Administrative Agent may execute any of its duties as Administrative Agent
hereunder and under any other Loan Document by or through employees, agents, and

or securities received by it or its authorized agents, for the default or
misconduct of any such agents or attorneys-in-fact selected by it with
reasonable care. The Administrative Agent shall be entitled to advice of counsel
concerning the contractual arrangement between the Administrative Agent and the
Lenders and all matters pertaining to the Administrative Agent's duties
hereunder and under any other Loan Document.

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

             9.8 Administrative Agent's Reimbursement and Indemnification. The
                 --------------------------------------------------------
Lenders agree to reimburse and indemnify the Administrative Agent ratably in
proportion to their respective Commitments (or, if the Commitments have been
terminated, in proportion to their Commitments immediately prior to such
termination) (i) for any amounts not reimbursed by the 

                                       46
<PAGE>
 
Borrower for which the Administrative Agent is entitled to reimbursement by the
Borrower under the Loan Documents, (ii) for any other expenses incurred by the
Administrative Agent on behalf of the Lenders, in connection with the
preparation, execution, delivery, administration and enforcement of the Loan
Documents (including, without limitation, for any expenses incurred by the
Administrative Agent in connection with any dispute between the Administrative
Agent and any Lender or between two or more of the Lenders) and (iii) for any
liabilities, obligations, losses, damages, penalties, actions, judgments, suits,
costs, expenses or disbursements of any kind and nature whatsoever which may be
imposed on, incurred by or asserted against the Administrative Agent in any way
relating to or arising out of the Loan Documents or any other document delivered
in connection therewith or the transactions contemplated thereby (including,
without limitation, for any such amounts incurred by or asserted against the
Administrative Agent in connection with any dispute between the Administrative
Agent and any Lender or between two or more of the Lenders), or the enforcement
of any of the terms of the Loan Documents or of any such other documents,
provided that no Lender shall be liable for any of the foregoing to the extent
- --------
any of the foregoing is found in a final non-appealable judgment by a court of
competent jurisdiction to have resulted from the gross negligence or willful
misconduct of the Administrative Agent. The obligations of the Lenders under
this subsection 9.8 shall survive payment of the Obligations and termination of
this Agreement.

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

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

Syndication Agent, the Documentation Agent, the Arrangers or any other Lender
and based on the financial statements prepared by the Borrower and such other
documents and information as it has deemed appropriate, made its own credit
analysis and decision to enter into this Agreement and the other Loan Documents.
Each Lender also acknowledges that it will, independently and without reliance
upon the Administrative Agent, the Syndication Agent, the Documentation Agent,
the Arrangers or any other Lender and based on such documents and information as
it shall deem 

                                       47
<PAGE>
 
appropriate at the time, continue to make its own credit decisions in taking or
not taking action under this Agreement and the other Loan Documents.

             9.12 Successor Administrative Agent. The Administrative Agent may
                  ------------------------------
resign at any time by giving written notice thereof to the Lenders and the
Borrower, such resignation to be effective upon the appointment of a successor
Administrative Agent or, if no successor Administrative Agent has been
appointed, forty-five days after the retiring Administrative Agent gives notice
of its intention to resign. The Administrative Agent may be removed at any time
with or without cause by written notice received by the Administrative Agent
from the Majority Lenders, such removal to be effective on the date specified by
the Majority Lenders. Upon any such resignation or removal, the Majority Lenders
shall have the right to appoint, on behalf of the Borrower and the Lenders, a
successor Administrative Agent. If no successor Administrative Agent shall have
been so appointed by the Majority Lenders within thirty days after the resigning
Administrative Agent's giving notice of its intention to resign, then the
resigning Administrative Agent may appoint, on behalf of the Borrower and the
Lenders, a successor Administrative Agent. Notwithstanding the previous
sentence, the Administrative Agent may at any time without the consent of the
Borrower or any Lender, appoint any of its Affiliates which is a commercial bank
as a successor Administrative Agent hereunder. If the Administrative Agent has
resigned or been removed and no successor Administrative Agent has been
appointed, the Lenders may perform all the duties of the Administrative Agent
hereunder and the Borrower shall make all payments in respect of the Obligations
to the applicable Lender and for all other purposes shall deal directly with the
Lenders. No successor Administrative Agent shall be deemed to be appointed
hereunder until such successor Administrative Agent has accepted the
appointment. Any such successor Administrative Agent shall be a commercial bank
having capital and retained earnings of at least $100,000,000. Upon the
acceptance of any appointment as Administrative Agent hereunder by a successor
Administrative Agent, such successor Administrative Agent shall thereupon
succeed to and become vested with all the rights, powers, privileges and duties
of the resigning or removed Administrative Agent. Upon the effectiveness of the
resignation or removal of the Administrative Agent, the resigning or removed
Administrative Agent shall be discharged from any future duties and obligations
hereunder and under the Loan Documents. After the effectiveness of the
resignation or removal of an Administrative Agent, the provisions of this
Section 9 shall continue in effect for the benefit of such Administrative Agent
in respect of any actions taken or omitted to be taken by it while it was acting
as the Administrative Agent hereunder and under the other Loan Documents.

             9.13 Administrative Agent's Fee. The Borrower agrees to pay to the

             9.14 Delegation to Affiliates. The Borrower and the Lenders agree
                  ------------------------
that the Administrative Agent may delegate any of its duties under this
Agreement to any of its Affiliates. Any such Affiliate (and such Affiliate's
directors, officers, agents and employees) which performs duties in connection
with this Agreement shall be entitled to the same benefits of the
indemnification, waiver and other protective provisions to which the
Administrative Agent is entitled under Sections 9 and 10.

counsel to each of the Arrangers, the Syndication Agent, and the Administrative
Agent, (b) to pay or reimburse each Lender, each of the Arrangers, the
Syndication Agent, and the Administrative Agent for all its costs and expenses
incurred in connection with the enforcement or preservation of any rights under
this Agreement, the other Loan Documents and any such other documents,
including, without limitation, the fees and disbursements of counsel (including
the allocated fees and expenses of in-house counsel) to each Lender and of
counsel to each of the Arrangers, the Syndication Agent, and the Administrative

and each of the Arrangers, the Syndication Agent, and the Administrative Agent
harmless from, any and all recording and filing fees and any and all liabilities
with respect to, or resulting from any delay in paying, stamp, excise and other
taxes, if any, which may be payable or determined to be payable in connection
with the execution and delivery of, or consummation or administration of any of
the transactions contemplated by, or any amendment, supplement or modification
of, or any waiver or consent under or in respect of, this Agreement, the other
Loan Documents and any such other documents, and (d) to pay, indemnify, and hold
each Lender, and each of the Arrangers, the Syndication Agent, and the
Administrative Agent harmless from and against any and all other liabilities,
obligations, losses, damages, penalties, actions, judgments, suits, costs,
expenses or disbursements of any kind or nature whatsoever with respect to the
execution, delivery, enforcement, performance and administration of this
Agreement, the other Loan Documents or the use of the proceeds of the Loans,
including, without limitation, any of the foregoing relating to the violation
of, noncompliance with or liability under, any Environmental Law applicable to
the operations of the Borrower, any of its Subsidiaries or any of the Properties
(all the foregoing in this clause (d), collectively, the "indemnified
liabilities"), provided that the Borrower shall have no obligation hereunder to
the Administrative Agent, the Syndication Agent, the Arrangers or any Lender
with respect to indemnified liabilities arising from the gross negligence or
willful misconduct of the Administrative Agent, the Syndication Agent, the
Arrangers or any such Lender, as applicable. The agreements in this subsection
shall survive repayment of the Loans and all other amounts payable hereunder.

             10.6 Successors and Assigns; Participations and Assignments. (a)
                  ------------------------------------------------------
This Agreement shall be binding upon and inure to the benefit of the Borrower,
the Lenders, the Administrative Agent and their respective successors and
assigns, except that the Borrower may not assign or transfer any of its rights
or obligations under this Agreement without the prior written consent of each
Lender.

             (b) Any Lender may, in the ordinary course of its commercial
banking business and in accordance with applicable law, at any time sell to one
or more banks or other entities ("Participants") participating interests in any
                                  ------------
Loan owing to such Lender, any Commitment of such Lender or any other interest
of such Lender hereunder and under the other Loan Documents; provided that, in
                                                             --------
the case of any such sale of a participating interest, the aggregate amount of
the L/C Obligations and the aggregate amount of the Available Commitment being
assigned is not less than $5,000,000 (or such lesser amount as may be agreed to
by the Administrative Agent). In the event of any such sale by a Lender of a
participating interest to a Participant, such Lender's obligations under this
Agreement to the other parties to this Agreement shall remain unchanged, such
Lender shall remain solely responsible for the performance thereof, such Lender
shall remain the holder of any such Loan for all purposes under this Agreement
and the other Loan Documents, and the Borrower and the Administrative Agent
shall continue to deal solely and directly with such Lender in connection with
such Lender's rights and obligations under this Agreement and the other Loan
Documents. No Lender shall be entitled to create in favor of any Participant, in
the participation agreement pursuant to which such Participant's participating
interest shall be created or otherwise, any right to vote on, consent to or
approve any matter relating to this Agreement or any other Loan Document except
for those specified in clauses (i) and (ii) of the proviso to subsection 10.1.
The Borrower agrees that if amounts outstanding under this Agreement are due or
unpaid, or shall have been declared or shall have become due and payable upon
the occurrence of an Event of Default, each Participant shall, to the maximum

                                       51
<PAGE>
 
extent permitted by applicable law, be deemed to have the right of setoff 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 Lender under this Agreement, provided that, in purchasing
                                                 --------
such participating interest, such Participant shall be deemed to have agreed to
share with the Lenders the proceeds thereof as provided in subsection 10.7(a) as
fully as if it were a Lender hereunder. The Borrower also agrees that each
Participant shall be entitled to the benefits of subsections 2.14, 2.15 and 2.16
with respect to its participation in the Commitments and the Loans outstanding
from time to time as if it was a Lender; provided that, in the case of
                                         --------
subsection 2.15, such Participant shall have complied with the requirements of
said subsection and provided, further, that no Participant shall be entitled to
                    --------  -------
receive any greater amount pursuant to any such subsection than the transferor
Lender would have been entitled to receive in respect of the amount of the
participation transferred by such transferor Lender to such Participant had no
such transfer occurred.

             (c) Any Lender may, in the ordinary course of its commercial
banking business and in accordance with applicable law, at any time and from
time to time assign to any Lender or any Affiliate thereof or, with the consent
of the Borrower, each Issuing Bank and the Administrative Agent (which in each
case shall not be unreasonably withheld), to an additional bank or financial
institution (an "Assignee") all or any part of its rights and obligations under
                 --------
this Agreement and the other Loan Documents pursuant to an Assignment and
Acceptance, substantially in the form of Exhibit D, executed by such Assignee,
such assigning Lender (and, in the case of an Assignee that is not then a Lender
or an Affiliate thereof, by the Borrower, each Issuing Bank and the
Administrative Agent) and delivered to the Administrative Agent for its
acceptance and recording in the Register, provided that, in the case of any such
                                          --------
assignment to an additional bank or financial institution, the sum of the
aggregate principal amount of the Loans, the aggregate amount of the L/C
Obligations and the aggregate amount of the Available Commitment being assigned
is not less than $5,000,000 (or such lesser amount as may be agreed to by the
Borrower and the Administrative Agent). Upon such execution, delivery,
acceptance and recording, from and after the effective date determined pursuant
to such Assignment and Acceptance, (x) the Assignee thereunder shall be a party
hereto and, to the extent provided in such Assignment and Acceptance, have the
rights and obligations of a Lender hereunder with a Commitment as set forth
therein, and (y) the assigning Lender thereunder shall, to the extent provided
in such Assignment and Acceptance, be released from its obligations under this
Agreement (and, in the case of an Assignment and Acceptance covering all or the
remaining portion of an assigning Lender's rights and obligations under this
Agreement, such assigning Lender shall cease to be a party hereto).
Notwithstanding any provision of this paragraph (c) and paragraph (e) of this
subsection, the consent of the Borrower shall not be required, and, unless
requested by the Assignee and/or the assigning Lender, new Notes shall not be
required to be executed and delivered by the Borrower, for any assignment which
occurs at any time when any Event of Default shall have occurred and be
continuing.

             (d) The Administrative Agent, on behalf of the Borrower, shall
maintain at the address of the Administrative Agent referred to in subsection
10.2 a copy of each Assignment and Acceptance delivered to it and a register
(the "Register") for the recordation of the names and addresses of the Lenders
      --------
and the Commitment of, and principal amounts of the Loans owing to, each Lender
from time to time. The entries in the Register shall be conclusive, in the
absence of manifest error, and the Borrower, the Administrative Agent and the
Lenders may (and, in the 

                                       52
<PAGE>
 
case of any Loan or other obligation hereunder not evidenced by a Note, shall)
treat each Person whose name is recorded in the Register as the owner of a Loan
or other obligation hereunder as the owner thereof for all purposes of this
Agreement and the other Loan Documents, notwithstanding any notice to the
contrary. Any assignment of any Loan or other obligation hereunder not evidenced
by a Note shall be effective only upon appropriate entries with respect thereto
being made in the Register.

             (e) Upon its receipt of an Assignment and Acceptance executed by an
assigning Lender and an Assignee (and, in the case of an Assignee that is not
then a Lender or an Affiliate thereof, by the Borrower and the Administrative
Agent) together with payment to the Administrative Agent of a registration and
processing fee of $3,000, the Administrative Agent shall (i) promptly accept
such Assignment and Acceptance and (ii) on the effective date determined
pursuant thereto record the information contained therein in the Register and
give notice of such acceptance and recordation to the Lenders and the Borrower.

             (f) The Borrower authorizes each Lender to disclose to any
Participant or Assignee (each, a "Transferee") and any prospective Transferee,
                                  ----------
subject to the provisions of subsection 10.15, any and all financial information
in such Lender's possession concerning the Borrower and its Affiliates which has
been delivered to such Lender by or on behalf of the Borrower pursuant to this
Agreement or which has been delivered to such Lender by or on behalf of the
Borrower in connection with such Lender's credit evaluation of the Borrower and
its Affiliates prior to becoming a party to this Agreement.

             (g) For avoidance of doubt, the parties to this Agreement
acknowledge that the provisions of this subsection concerning assignments of
Loans and Notes relate only to absolute assignments and that such provisions do
not prohibit assignments creating security interests, including, without
limitation, any pledge or assignment by a Lender of any Loan or Note to any
Federal Reserve Bank in accordance with applicable law.

             10.7 Adjustments; Set-off. (a) If any Lender (a "benefitted
                  --------------------                        ----------
Lender") at any time shall receive any payment of all or part of its Loans or
- ------
the Reimbursement Obligations owing to it, or interest thereon, or receive any
collateral in respect thereof (whether voluntarily or involuntarily, by set-off,
pursuant to events or proceedings of the nature referred to in Section 8(f) or
otherwise), in a greater proportion than any such payment to or collateral
received by any other Lender, if any, in respect of such other Lender's Loans or
the Reimbursement Obligations owing to it, or interest thereon, such benefitted
Lender shall purchase for cash from the other Lenders such portion of each such
other Lender's Loan or the Reimbursement Obligations owing to it, or shall
provide such other Lenders with the benefits of any such collateral, or the
proceeds thereof, as shall be necessary to cause such benefitted Lender to share
the excess payment or benefits of such collateral or proceeds ratably with each
of the Lenders; provided, however, that if all or any portion of such excess
                --------  -------
payment or benefits is thereafter recovered from such benefitted Lender, such
purchase shall be rescinded, and the purchase price and benefits returned, to
the extent of such recovery, but without interest. The Borrower agrees that each
Lender so purchasing a portion of another Lender's Loan may exercise all rights
of payment (including, without limitation, rights of set-off) with respect to
such portion as fully as if such Lender were the direct holder of such portion.

                                       53
<PAGE>
 
             (b) In addition to any rights and remedies of the Lenders provided
by law, each Lender shall have the right, without prior notice to the Borrower,
any such notice being expressly waived by the Borrower to the extent permitted
by applicable law, upon any amount becoming due and payable by the Borrower
hereunder (whether at the stated maturity, by acceleration or otherwise) to
set-off and appropriate and apply against such amount any and all deposits
(general or special, time or demand, provisional or final), in any currency, and
any other credits, indebtedness or claims, in any currency, in each case whether
direct or indirect, absolute or contingent, matured or unmatured, at any time
held or owing by such Lender or any branch or agency or Affiliate thereof to or
for the credit or the account of the Borrower. Each Lender agrees promptly to
notify the Borrower and the Administrative Agent after any such set-off and
application made by such Lender, provided that the failure to give such notice
                                 --------
shall not affect the validity of such set-off and application.

             10.8 Counterparts. This Agreement may be executed by one or more of
                  ------------
the parties to this Agreement on any number of separate counterparts (including
by facsimile transmission), and all of said counterparts taken together shall be
deemed to constitute one and the same instrument. A set of the copies of this
Agreement signed by all the parties shall be lodged with the Borrower and the
Administrative Agent.

             10.9 Severability. Any provision of this Agreement which is
                  ------------
prohibited or unenforceable in any jurisdiction shall, as to such jurisdiction,
be ineffective to the extent of such prohibition or unenforceability without
invalidating the remaining provisions hereof, and any such prohibition or
unenforceability in any jurisdiction shall not invalidate or render
unenforceable such provision in any other jurisdiction.

             10.10 Integration. This Agreement and the other Loan Documents
                   -----------
represent the entire agreement of the Borrower, the Administrative Agent and the
Lenders with respect to the subject matter hereof and supersedes all prior
agreements, understandings, negotiations and discussions, whether oral or
written, of the parties hereto relating to the subject matter hereof, and there
are no promises, undertakings, representations or warranties by the
Administrative Agent or any Lender relative to subject matter hereof not
expressly set forth or referred to herein or in the other Loan Documents.

             10.11 GOVERNING LAW. THIS AGREEMENT AND THE RIGHTS AND OBLIGATIONS
                   -------------
OF THE PARTIES HEREUNDER SHALL BE GOVERNED BY, AND CONSTRUED AND INTERPRETED IN
ACCORDANCE WITH, THE INTERNAL SUBSTANTIVE LAW OF THE STATE OF NEW YORK WITHOUT
REGARD TO CONFLICTS OF LAWS PRINCIPLES.

             10.12 Submission To Jurisdiction; Waivers. The Borrower hereby
                   -----------------------------------
irrevocably and unconditionally:

             (a) submits for itself and its property in any legal action or
       proceeding relating to this Agreement and the other Loan Documents to
       which it is a party, or for recognition and enforcement of any judgement
       in respect thereof, to the non-exclusive general jurisdiction of the
       Courts of the State of New York, the courts of the United States of
       America for the Southern District of New York, and appellate courts from
       any thereof;

                                       54
<PAGE>
 
             (b) consents that any such action or proceeding may be brought in
       such courts and waives any objection that it may now or hereafter have to
       the venue of any such action or proceeding in any such court or that such
       action or proceeding was brought in an inconvenient court and agrees not
       to plead or claim the same;

             (c) agrees that service of process in any such action or
       proceeding may be effected by mailing a copy thereof by registered or
       certified mail (or any substantially similar form of mail), postage
       prepaid, to the Borrower at its address set forth in subsection 10.2 or
       at such other address of which the Administrative Agent shall have been
       notified pursuant thereto;

             (d) agrees that nothing herein shall affect the right to effect
       service of process in any other manner permitted by law or shall limit
       the right to sue in any other jurisdiction; and

             (e) waives, to the maximum extent not prohibited by law, any right
       it may have to claim or recover in any legal action or proceeding
       referred to in this subsection any special, exemplary, punitive or
       consequential damages.

             10.13 Nonliability of Lenders. The relationship between the
                   -----------------------
Borrower on the one hand and the Lenders and the Administrative Agent and the
Syndication Agent on the other hand shall be solely that of borrower and lender.
Neither the Administrative Agent, the Syndication Agent, the Arrangers nor any
Lender shall have any fiduciary responsibilities to the Borrower. Neither the
Administrative Agent, the Syndication Agent, the Arrangers nor any Lender
undertakes any responsibility to the Borrower to review or inform the Borrower
of any matter in connection with any phase of the Borrower's business or
operations. The Borrower agrees that neither the Administrative Agent, the
Syndication Agent, the Arrangers nor any Lender shall have liability to the
Borrower (whether sounding in tort, contract or otherwise) for losses suffered
by the Borrower in connection with, arising out of, or in any way related to,
the transactions contemplated and the relationship established by the Loan
Documents, or any act, omission or event occurring in connection therewith,
unless it is determined in a final non-appealable judgment by a court of
competent jurisdiction that such losses resulted from the gross negligence or
willful misconduct of the party from which recovery is sought.

             10.14 WAIVERS OF JURY TRIAL. THE BORROWER, THE ADMINISTRATIVE AGENT
                   ---------------------
AND THE LENDERS HEREBY IRREVOCABLY AND UNCONDITIONALLY WAIVE TRIAL BY JURY IN
ANY LEGAL ACTION OR PROCEEDING RELATING TO THIS AGREEMENT OR ANY OTHER LOAN
DOCUMENT AND FOR ANY COUNTERCLAIM THEREIN.

             10.15 Confidentiality. Each Lender agrees to keep confidential all
                   ---------------
non-public information provided to it by the Borrower pursuant to this Agreement
that is known to be or is designated by the Borrower in writing as confidential;
provided that nothing herein shall prevent any Lender from disclosing any such
- --------
information (i) to the Administrative Agent or any other Lender, (ii) to any
Transferee or prospective Transferee which agrees to comply in a binding written
agreement (which may be in a form similar to Exhibit E hereto) with the
provisions of this subsection, (iii) to its employees, directors, agents,
attorneys, accountants and other 

                                       55
<PAGE>
 
professional advisors that need to know such information, (iv) upon the request
or demand of any Governmental Authority having jurisdiction over such Lender,
(v) in response to any order of any court or other Governmental Authority or as
may otherwise be required pursuant to any Requirement of Law, (vi) which has
been publicly disclosed other than in breach of this Agreement, or (vii) in
connection with any legal proceeding brought in connection with the exercise of
any remedy hereunder.

</TABLE> 

For purposes of computing the ratio, earnings are net income plus income taxes
and fixed charges, less nonutility capitalized interest.  Fixed charges consist
of interest on long- and short-term debt, amortization of debt discount,
premium, and expense, preferred stock dividend requirements of subsidiaries, and
interest on leases.  Preferred dividend requirements for purposes of computing
the ratio have been increased to an amount representing the pre-tax earnings
which would be required to cover such dividend requirements.
