              NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
                               September 30, 1999

                                   (Unaudited)


(1)  SIGNIFICANT ACCOUNTING POLICIES

         We, the management of Health Care Property Investors, Inc., believe
that the unaudited financial information contained in this report reflects all
adjustments that are necessary to state fairly the financial position, the
results of operations, and cash flows of the Company. Unless the context
otherwise indicates, the Company or HCPI means Health Care Property Investors,
Inc. and its affiliated subsidiaries and joint ventures. We presume that users
of this interim financial information have read or have access to the audited
financial statements and Management's Discussion and Analysis of Financial
Condition and Results of Operations for the preceding fiscal year ended December
31, 1998. Therefore, notes to the financial statements and other disclosures
that would repeat the disclosures contained in our most recent annual report to
security holders have been omitted. This interim financial information does not
necessarily represent a full year's operations for various reasons including
acquisitions and dispositions, changes in rents and interest rates, and the
timing of debt and equity financings.

Facility Operations:

         Since November 1997, we have purchased ownership interests (ranging
from 50 to 100 percent) in 42 medical office buildings ("MOBs") that are
operated by independent property management companies on our behalf. We lease
these facilities to multiple tenants. Amounts recovered from tenants as
reimbursements of operating costs incurred under such leases are recorded as
Tenant Reimbursements. Expenses related to the operation of these facilities are
recorded as Facility Operating Expenses.

Reclassifications:

         We have made reclassifications, where necessary, for comparative
financial statement presentations.

(2)  MAJOR OPERATORS

         As of September 30, 1999, we owned properties in 42 states operated by
85 operators. In addition, approximately 250 tenants conducted business in our
multi-tenant buildings. Listed below are our major operators, the number of
facilities operated by these operators, the annualized revenue as of September
30, 1999 and the percentage of annualized revenue, in each case, for the nine
months ended September 30, 1999, from these operators and their subsidiaries:

     Certain facilities leased to operators listed above have been subleased to
other operators with the original lessees remaining liable on the leases. The
number of facilities, annualized revenue, and percentages of our total
annualized revenue applicable to these sublessees are not included above. The
percentage of our total annualized revenue on facilities leased to Vencor and
subleased to other operators was 2.5% as of September 30, 1999. As discussed in
more detail below, we have recourse to Tenet and Ventas, Inc. for rent
obligations under most Vencor leases.

         All these major operators are subject to the informational filing
requirements of the Securities Exchange Act of 1934 and accordingly file
periodic financial statements on Form 10-K and Form 10-Q with the Securities and
Exchange Commission.

Vencor

         On May 1, 1998, Vencor completed a spin-off transaction. As a result,
it became two publicly held entities--Ventas, Inc., a real estate company which
intends to qualify as a REIT, and Vencor, a health care company which at
September 30, 1999 leased 36 of HCPI's properties of which 14 are subleased to
other operators. On September 13, 1999, Vencor, Inc. filed for bankruptcy
protection. The Company has recourse to Ventas, Inc. and Tenet Healthcare
Corporation (see discussion under Tenet below) for most of the rents payable by
Vencor under its leases. All rents due to the Company subsequent to the filing
have been received.

         Vencor has an obligation to pay rents due to the Company prior to
filing for bankruptcy protection. However, Vencor has the right to assume or
reject its leases with us. If Vencor assumes a lease it must do so pursuant to
the original contract terms, must cure all pre-petition and post-petition
defaults under the lease and provide adequate assurances of future performance.
If Vencor rejects a lease, it may stop paying rent and we may lease the property
to another operator. As of November 10, 1999, Vencor had made no proposals to
reject any of their current leases with the Company. We expect to collect
pre-bankruptcy receivables of $993,000 and future rents. However, we cannot
assure you that as a result of Vencor's bankruptcy filing we would be able to
recover all amounts due under our leases with Vencor, that we would be able to
promptly recover the premises or lease the property to another lessee or that
the rent we would receive from another lessee would equal amounts due under the
Vencor leases. We have recourse to Tenet for rents under all but five of the
Vencor leases, and on some leases we are receiving direct payment by sublessees
of Vencor, which may reduce the risk to us of not being able to collect on those
leases. However, we cannot assure you that the bankruptcy filing of Vencor would
not have a material adverse effect on our Net Income, Funds From Operations or
the market value

of our common stock.

Tenet

         Tenet is one of the nation's largest health care services companies,
providing a broad range of services through the ownership and management of
health care facilities. Tenet has historically guaranteed Vencor's leases.
During 1997 we reached an agreement with Tenet whereby Tenet agreed to forbear
or waive some renewal and purchase options and related rights of first refusal
on facilities leased to Vencor. As part of that same agreement, we only have
recourse to Tenet for the rent payments on the Vencor leases until the end of
their base term. Of the 36 leases for which we have recourse to Tenet, at
December 31, 1998, five expired during the nine months ended September 30, 1999.
The remaining 31 guaranteed leases expire during the next two years.

(3)      REAL ESTATE INVESTMENTS AND DISPOSITIONS

         During the nine months ended September 30, 1999, we acquired seven
clinics, one assisted living facility, 4 MOBs and an ownership interest in 15
additional MOBs for an aggregate investment of approximately $170,000,000.

         During the nine months ended September 30, 1999, we sold six facilities
and ownership interests in four facilities, resulting in a net gain of
$10,303,000.

(5)  EARNINGS PER COMMON SHARE

         The Company adopted Statement of Financial Accounting Standards No.
128, Earnings Per Share, effective December 15, 1997. As a result, both basic
and diluted earnings per common share are presented for each of the quarters and
nine months ended September 30, 1999 and 1998. Prior to 1997, only basic
earnings per common share were disclosed. Basic earnings per common share is
computed



                                      -7-
<PAGE>   9



by dividing Net Income applicable to common shares by the weighted average
number of shares of common stock outstanding during the period. Diluted earnings
per common share is calculated including the effect of dilutive securities.
Options to purchase shares of common stock that had an exercise price in excess
of the average market price of the common stock during the period were not
included because they are not dilutive.

(6)  FUNDS FROM OPERATIONS

         Effective in 1998, the Statement of Financial Accounting Standards No.
131, Disclosures about Segments of an Enterprise, requires that we report
information about our operations on the same basis that is used internally to
measure performance.

          We believe that Funds From Operations ("FFO") is our most important
internal supplemental measure of operating performance. Because the historical
cost accounting convention used for real estate assets requires straight-line
depreciation (except on land) such accounting presentation implies that the
value of real estate assets diminishes predictably over time. Because real
estate values instead have historically risen and fallen with market conditions,
presentations of operating results for a real estate investment trust that uses
historical cost accounting for depreciation could be less informative. The term
FFO was designed by the real estate investment trust industry to address this
problem.

         The Company adopted the definition of FFO prescribed by the National
Association of Real Estate Investment Trusts ("NAREIT"). FFO is defined as Net
Income applicable to common shares (computed in accordance with generally
accepted accounting principles), excluding gains (or losses) from debt
restructuring and sales of property, plus real estate depreciation and real
estate related



                                      -8-
<PAGE>   10

amortization, and after adjustments for unconsolidated partnerships and joint
ventures. Adjustments for unconsolidated partnerships and joint ventures are
calculated to reflect FFO on the same basis.

         FFO does not represent cash generated from operating activities in
accordance with generally accepted accounting principles, is not necessarily
indicative of cash available to fund cash needs and should not be considered as
an alternative to Net Income. FFO, as defined by the Company, may not be
comparable to similarly entitled items reported by other real estate investment
trusts that do not define it exactly as the NAREIT definition.

         Below are summaries of the calculation of FFO (all amounts in
thousands):

(7)  COMMITMENTS

         As of November 10, 1999, the Company has acquired real estate
properties and has outstanding commitments to fund development of health care
facilities of approximately $37,000,000.

         The Company is also committed to acquire approximately $15,000,000 of
existing health care real estate. The Company expects that a significant portion
of these commitments will be funded; however, experience suggests that some
committed transactions will not close. The letters of intent representing such
commitments permit either party to elect not to go forward with the transaction
under various circumstances. We may not close committed transactions for various
reasons including unsatisfied pre-closing conditions, competitive financing
sources, final negotiation differences or the operator's inability to obtain
required internal or governmental approvals.

(8)  NEW PRONOUNCEMENTS

         In June 1998, the Financial Accounting Standards Board issued Statement
of Financial Accounting Standards No. 133, Accounting for Derivative Instruments
and Hedging Activities. The Statement establishes accounting and reporting
standards requiring that every derivative instrument (including certain
derivative instruments embedded in other contracts) be recorded in the balance
sheet as either an asset or liability measured at its fair value. The Statement
requires that changes in the derivative's fair value be recognized currently in
earnings unless specific hedge accounting criteria are met. Statement 133 is
effective for fiscal years beginning after June 15, 2000, although earlier
implementation is allowed.

         We have not yet quantified the impact of adopting Statement 133 on our
financial statements and have not determined the timing or method of our
adoption of Statement 133. However, the effect is not expected to be material.

(9)  SUBSEQUENT EVENTS

         On November 4, 1999, American Health Properties, Inc. ("AHE") merged
with and into HCPI ("the Merger") in a stock-for-stock transaction, approved by
the stockholders of both companies, with Health Care Property Investors being
the surviving corporation. AHE was a real estate investment trust specializing
in health care facilities with a portfolio of 68 health care properties in 22
states. Under the terms of the merger agreement, each share of AHE common stock
was converted into the right to receive 0.78 share of HCPI's common stock and
each outstanding share of AHE's 8.60% cumulative redeemable preferred stock,
Series B (represented by depository shares) was converted as discussed below
into shares of HCPI 8.60% Series C cumulative redeemable preferred stock (also
represented by depository shares) redeemable at HCPI's option on and after
October 27, 2002. The Merger resulted in the issuance of approximately
19,491,735 shares of HCPI's common stock and 40,000 shares of HCPI's Series C
cumulative redeemable preferred stock with a liquidation preference of $100
million. Additionally, HCPI assumed $325 million of AHE's debt upon consummation
of the Merger. The transaction will be treated as a purchase for financial
accounting purposes. As a result of the Merger, HCPI owns interests in 424
health care properties in 43 states.

         On November 2, 1999, HCPI obtained new senior revolving credit
facilities totaling $310,000,000. The new credit facilities became effective on
November 4, 1999 upon consummation of the Merger. These facilities include a
$207,000,000 line which expires after four years and a $103,000,000 line which
expires November 2000. A portion of the proceeds of these facilities was used to
refinance the Company's existing revolving credit facility of $90,000,000 and
$71,000,000 of AHE's revolving credit facilities outstanding immediately prior
to the Merger. As of November 10, 1999, the Company had $133,500,000 in
available borrowings under the new revolving credit facilities.

         On October 8, 1999 the Board of Directors declared a quarterly dividend
of $0.71 per common share payable on November 19, 1999, to shareholders of
record on the close of business on October 21, 1999.

         The Board of Directors also declared a cash dividend of $0.492188 per
share on its Series A cumulative preferred stock and $0.54375 per share on its
Series B cumulative preferred stock. These dividends will be paid on December
31, 1999 to shareholders of record as of the close of business on December 15,
1999.

         On November 3, 1999, the Board of Directors declared a cash dividend,
effective upon the consummation of the merger with American Health Properties,
Inc., of $53.75 per share (representing dividends from August 30, 1999 to
November 30, 1999) for every share of the Company's 8.60% Series C cumulative
redeemable preferred stock ($.5375 per depositary share representing 1/100th of
a share of Series C preferred stock) to be issued in connection with the merger.
This dividend is payable on November 30, 1999 to holders of record of the Series
C preferred stock on November 15, 1999. Also on November 3, 1999, the Board of
Directors declared a cash dividend, effective upon the consummation of the
merger, of $17.9167 per share (representing dividends from December 1 to
December 31, 1999) for every share of the Series C preferred stock ($.179167 per
depositary share representing 1/100th of a share of Series C preferred stock).
This dividend is payable on December 31, 1999 to holders of record of the Series
C preferred stock on December 15, 1999.

                      HEALTH CARE PROPERTY INVESTORS, INC.
           MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION
                            AND RESULTS OF OPERATIONS


GENERAL

         The Company is in the business of acquiring health care facilities that
we lease on a long-term basis to health care providers. On a more limited basis,
we have provided mortgage financing on health care facilities. As of September
30, 1999, the Company's portfolio of properties, including equity investments,
consisted of 352 facilities located in 42 states. These facilities are comprised
of 157 long-term care facilities, 80 congregate care and assisted living
facilities, 46 physician group practice clinics, 54 medical office buildings,
eight acute care hospitals, six freestanding rehabilitation facilities and one
psychiatric care facility. The gross investment in the properties, which
includes joint venture acquisitions, was approximately $1.7 billion at September
30, 1999.

         We have commitments to purchase and construct health care facilities
totaling approximately $52,000,000 which are expected to fund during 1999 and
2000. We expect that a significant portion of these commitments will be funded
but that a portion may not be funded (see Note (7) to the Condensed Consolidated
Financial Statements).

         On November 4, 1999, the Company completed a merger with American
Health Properties in a stock-for-stock transaction (see Note (9) to the
Condensed Consolidated Financial Statements).

RESULTS OF OPERATIONS

         Net Income applicable to common shares for the three and nine months
ended September 30, 1999 totaled $26,064,000 and $56,899,000 or $0.81 and $1.80
of basic earnings per share on revenue of $52,218,000 and $153,651,000,
respectively. This compares to $22,836,000 and $55,679,000 or $0.74 and $1.82 of
basic earnings per share on revenue of $42,166,000 and $116,448,000 for the same
periods in 1998. Net Income applicable to common shares for the three months
ended September 30, 1999 and September 30, 1998 included a $10,151,000 or $0.32
per share and $6,230,000 or $0.20 per share gain on the sale of real estate
properties, respectively, and the nine months ended September 30, 1999 and 1998
included a $10,303,000 or $0.33 per share and $6,742,000 or $0.22 per share gain
on sale of real estate properties, respectively.

         Rental Income and Tenant Reimbursements for the three and nine months
ended September 30, 1999 increased $10,371,000 and $36,214,000 to $45,582,000
and $134,639,000, respectively, as compared to the same period in the prior
year. The majority of the increase in Rental Income was generated by new
investments of approximately $147,000,000 and $458,000,000 made during 1999 and
1998. Interest and Other Income for the three and nine months ended September
30, 1999 decreased $319,000 and increased $989,000 to $6,636,000 and
$19,012,000, respectively, primarily from growth in the lending portfolio offset
but the divestiture of certain partnership interests during the three months
ended September 30, 1999. There were $4,136,000 and $11,894,000 in related
Facility Operating Expenses during the three and nine months ended September 30,
1999 compared to $1,466,000 and $3,211,000 during the three and nine months
ended September 30, 1998 resulting from additional multi-tenant leases under
which the Company is responsible for operating expenses of the leased facility.



                                      -11-
<PAGE>   13

         Interest Expense for the three and nine months ended September 30, 1999
increased $3,462,000 and $12,769,000, respectively. The increase is primarily
the result of an increase in short-term borrowings used to fund the acquisitions
made during the fourth quarter of 1998 and the nine months ended September 30,
1999 and interest related to the MOPPRS senior debt issuance during June 1998.
The increase in Depreciation/Non Cash Charges for the three and nine months
ended September 30, 1999 of $2,629,000 and $8,309,000 to $10,995,000 and
$32,059,000, respectively, is the direct result of the new investments made
during 1999 and 1998.

         We believe that FFO is an important supplemental measure of operating
performance. FFO for the nine months ended September 30, 1999 increased
$2,239,000 to $26,546,000 as compared to the same period in the prior year. The
increase is attributable to increases in Rental Income, and Interest and Other
Income, as offset by increases in Interest Expense and Facility Operating
Expenses, which are discussed above.

         FFO does not represent cash generated from operating activities in
accordance with generally accepted accounting principles, is not necessarily
indicative of cash available to fund cash needs and should not be considered as
an alternative to Net Income. FFO, as we defined it, may not be comparable to
similarly entitled items reported by other real estate investment trusts that do
not use the NAREIT definition.

LIQUIDITY AND CAPITAL RESOURCES

         The Company has financed acquisitions through the sale of common and
preferred stock, issuance of long-term debt, assumption of mortgage debt, use of
short-term bank lines and through internally generated cash flows. Facilities
under construction are generally financed by means of cash on hand or short-term
borrowings under our existing bank lines. At the completion of construction and
commencement of the lease, short-term borrowings used in the construction phase
are generally refinanced with new long-term debt, including Medium Term Notes
("MTNs"), or with equity offerings.

SENIOR DEBT OFFERINGS

         During June 1998, the Company issued $200 million of 6.875% MandatOry
Par Put Remarketed Securities ("MOPPRS") due June 8, 2015 which are subject to
mandatory tender on June 8, 2005. We



                                      -12-

received total proceeds of approximately $203,000,000 (including the present
value of a put option associated with the debt) which was used to repay
borrowings under our revolving lines of credit. The weighted average cost of the
debt including the amortization of the option and offering expenses is 6.77%.
The MOPPRS are senior, unsecured obligations of the Company.

</TABLE>


         HCPI used the net proceeds from the equity offerings to pay down or pay
off short-term borrowings under its revolving lines of credit. HCPI invested any
excess funds in short-term investments until they were needed for acquisitions
or development.

         At September 30, 1999, stockholders' equity totaled $617,875,000 and
the debt to equity ratio was 1.31 to 1.00. For the nine months ended September
30, 1999, FFO (before interest expense) covered Interest Expense 3.0 to 1.0.

AVAILABLE FINANCING SOURCES

         During June 1998, the Company registered $600,000,000 of debt and
equity securities under a shelf registration statement filed with the Securities
and Exchange Commission. As of November 10, 1999 we had approximately
$397,000,000 remaining on shelf filings for future financings. Of that amount,
we had approximately $110,000,000 available under our MTN senior debt programs.
We may issue securities under our universal shelf, including under our MTN
programs, up to these amounts from time to time in the future based on Company
needs and then existing market conditions. As of November 10, 1999, the Company
had $133,500,000 in available borrowings under its new $310,000,000 revolving
credit facility (See Note (9) to the Condensed Consolidated Financial
Statements). Since 1986 the debt rating agencies have rated our Senior Notes and
Convertible Subordinated Notes investment grade. Current ratings are as follows:

         Since inception in May 1985, the Company has recorded approximately
$768,077,000 in cumulative FFO. Of this amount, we have distributed a total of
$644,520,000 to stockholders as dividends on common stock. We have retained the
balance of $123,557,000 and used it as an additional source of capital.




                                      -14-

         At November 10, 1999, the Company held approximately $42,900,000 in
irrevocable letters of credit from commercial banks to secure the obligations of
many lessees' lease and borrowers' loan obligations. We may draw upon the
letters of credit if there are any defaults under the leases and/or loans.
Amounts available under letters of credit could change based upon facility
operating conditions and other factors and such changes may be material.

         We paid the third quarter 1999 dividend of $0.70 per common share or
$22,400,000 in the aggregate on August 20, 1999. Total dividends paid during the
nine months ended September 30, 1999, as a percentage of FFO was 85%. The
Company declared a fourth quarter dividend of $0.71 per common share or
approximately $22,750,000 in the aggregate, payable on November 19, 1999.

         Management believes that HCPI's liquidity and sources of capital are
adequate to finance its operations as well as its future investments in
additional facilities.

FACILITY ROLLOVERS

         HCPI has concluded a significant number of "facility rollover"
transactions since 1995 on properties that have been under long-term leases and
mortgages. Facility rollover transactions principally include lease renewals and
renegotiations, exchanges, sales of properties, and, to a lesser extent, payoffs
on mortgage receivables. The annualized impact was to increase FFO in 1995 by
$900,000 and decrease FFO in each of the years 1996 through 1999 by $1,200,000,
$1,600,000, $3,100,000 and $3,200,000, respectively. Total rollovers were 20
facilities, 20 facilities, 12 facilities, 44 facilities and 21 facilities in
each of the years 1995 - 1999.

         Between November 10, 1999 and December 31, 2000, HCPI has nine
facilities that are subject to lease expiration and mortgage maturities. The
facilities remaining which are subject to lease expiration and mortgage
maturities during the remaining period in 1999 and  2000 aggregate 2.8% of
annualized revenue.

         During 1997, HCPI reached agreement with Tenet (the holder of
substantially all of the option rights of the Vencor leases) whereby Tenet
agreed to waive renewal and purchase options, and related rights of first
refusal, on up to 51 facilities. As part of these agreements, HCPI has the right
to continue to own the facilities. HCPI paid Tenet $5,000,000 in cash,
accelerated the purchase option on two acute care hospitals leased to Tenet, and
reduced Tenet's guarantees on the facilities leased to Vencor. Leases on 20 of
those 51 facilities had expiration dates through December 31, 2000. HCPI has
increased rents on five of the facilities with leases that have already expired
during 1998, and believes it will be able to increase rents on other facilities
whose lease terms expire through 2001. However, there can be no assurance that
HCPI will be able to realize any increased rents on future rollovers.

INTERNAL GROWTH

         For the three and nine months ended September 30, 1999, the Company had
internal same facility rent growth of approximately $518,000 and $1,412,000
or 2.5% of prior period rents in its portfolio, respectively.

TENANT ISSUES

         We have discussed issues regarding Vencor in Note (2) to the financial
statements. In addition, a number of other nursing home operators have also
been adversely affected by the decrease in Medicare reimbursements following the
adoption of the Prospective Payment System. As discussed in our Annual Report on
Form 10K for the year ended December 31, 1998, during the first quarter of 1999
certain of




                                      -15-
<PAGE>   17

these operators were put on credit watch with negative implications.
Subsequently, three of our operators (other than Vencor discussed separately)
have filed for bankruptcy protection: Texas Health Enterprises, Inc. filed on
August 3, 1999; Sun Healthcare Group filed on October 14, 1999; and Lenox
Healthcare, Inc. filed on November 3, 1999. Collectively, these operators
represented less than 4.8% of our annualized revenues for the period ended
September 30, 1999 and no one of these operators represented more than 1.8% of
annualized revenues for that same period. Giving effect to our merger with
American Health Properties, these operators represented less than 3.0% of
annualized revenue on a pro forma basis for the period ended September 30, 1999.
In addition, because facilities operated by these operators are performing well,
we believe the financial impact to HCPI of the bankruptcies by these tenants
will be minimal.


YEAR 2000 ISSUE

         The Year 2000 issue is the result of widely used computer programs that
identify the year by two digits, rather than by four. It is believed that
continued use of these programs may result in widespread computer-generated
malfunctions and miscalculations beginning in the year 2000, when the digits
"00" are interpreted as "1900." Those miscalculations could cause disruption of
operations including the temporary inability to process transactions such as
invoices for payment. Those computer programs that identify the year based on
all four digits are considered "Year 2000 compliant." The statements in the
following section include "Year 2000 readiness disclosure" within the meaning of
the Year 2000 Information and Readiness Disclosure Act of 1998.

Status of Year 2000 Issues with HCPI's Own Information Technology Systems and
Non-IT Systems

         Our primary use of information technology ("IT") is in our financial
accounting systems, billing and collection systems and other information
management software. We have been working with our computer consultants to test
and continually upgrade our management information systems. We have reasonable
assurance from our vendors, outside computer consultants and through our own
testing that our financial and other information systems are Year 2000
compliant. During 1998 and 1999, we inventoried our information technology
systems (including workstations, servers and software applications) and have
obtained the latest upgrades and patches from our vendors that would result in
all of our systems being Year 2000 compliant. The cost to bring the management
information systems into Year 2000 compliance has not been material. By
September 30, 1999, we had completed Y2K testing of our financial accounting
system. The test included mirroring the current environment, posting December
1999 transactions, closing of the year 1999, posting January 2000 transactions
and posting transactions in the leap year February 29, 2000. Upon completion of
the testing, we found no Y2K issues.

         Our operations are conducted out of our corporate offices in Newport
Beach, California where we use and are exposed to non-IT systems such as those
contained in embedded micro-processors in telephone and voicemail systems,
elevators, heating, ventilation and air conditioning (HVAC) systems, lighting
timers, security systems, and other property operational control systems. We
believe that we do not have significant exposure to Year 2000 issues with
respect to our non-IT systems contained in embedded chips used in our corporate
offices. While any disruption in services at our corporate offices due to
failure of non-IT systems may be inconvenient and disruptive to normal
day-to-day activities, it is not expected to have a materially adverse effect on
our financial performance or operations.



                                      -16-
<PAGE>   18

Exposure to Third Parties' Year 2000 Issues

         Because we believe our own accounting and information systems are Year
2000 compliant, we do not feel there will be material disruption to our
transaction processing on January 1, 2000. However, we depend upon our tenants
for rents and cash flows, our financial institutions for availability of working
capital and capital markets financing and our transfer agent to maintain and
track investor information. As health care providers, our operators, lessees and
mortgagors rely on critical clinical systems, medical devices and equipment in
the delivery of patient care; failures in those systems as a result of Year 2000
issues could have a material adverse effect on their results of operations or
expose them to liability. Furthermore, our operators, lessees and mortgagors are
dependent on a variety of third parties, including insurance companies, HMOs and
other private payors, governmental agencies that administer Medicaid and
Medicare claims processing and reimbursement, utilities that provide
electricity, water, natural gas and communications services and vendors of
medical supplies, pharmaceuticals, medical devices and equipment, all of whom
must also adequately address the Year 2000 issue. If our primary lessees and
mortgagors are not Year 2000 compliant, or if they face disruptions in their
cash flows due to Year 2000 issues, we could face significant temporary
disruptions in our cash flows after that date. These disruptions could be
exacerbated if the commercial banks that process our cash receipts and
disbursements and our lending institutions are not Year 2000 compliant.
Furthermore, to the extent there are broad market disruptions as a result of
widespread Year 2000 issues, our access to the capital markets to raise cash for
investing activity could be impaired.

         To address this concern, during the second quarter of 1998, we
commenced a written survey of all of our major tenants, Bank of New York in its
capacity as agent under our credit facilities, and as common stock Transfer
Agent and Trustee under our senior debt indenture, each other lender under our
credit facility, our primary investment banker for our capital raising
activities, and our independent public accountants and primary outside legal
counsel. The survey asked each respondent to assess its exposure to Year 2000
issues and asked what preparations each has made to deal with the Year 2000
issue with respect to both information technology and non-IT systems. In
addition, we asked each respondent to inform us about their exposure to third
party vendors, customers and payers who may not be Year 2000 compliant.

         Through this process we have been informed in writing by approximately
95% of those surveyed that they believe that they have computer systems that are
or will be Year 2000 compliant by the end of 1999. All continue to assess their
own exposure to the issue. However neither we nor our lessees and mortgagors can
be assured that the third parties upon which our operators, lessees and
mortgagors depend will accomplish adequate remediation of their Year 2000
issues, nor that the federal and state governments, upon which they rely for
Medicare and Medicaid revenue, will be in compliance in a timely manner.

         We are in the process of assessing our exposure to failures of embedded
microprocessors contained in elevators, electrical and HVAC systems, security
systems and the breakdown of other non-IT systems due to the Year 2000 issue at
the properties operated by our tenants. Under a significant portion of our
leases, we are not responsible for the cost to repair such items and are
indemnified by the tenants for losses caused by their operations on the
property. For the managed medical office buildings where we are responsible for
the building operations, we had the management companies inventory and assess
the building systems and our IT systems. The management companies represented to
us that they have implemented extensive Y2K compliance programs; as such, we
believe that the costs of repairs will



                                      -17-
<PAGE>   19

be immaterial and any such costs will be expensed as incurred. We believe that
these buildings will beY2K compliant by the end of 1999.

Risks of Year 2000 Issues

         Our exposure to the Year 2000 issue depends primarily on the readiness
of our significant tenants and commercial banks, who in turn, are dependent upon
suppliers, payers and other external parties, all of which is outside our
control. We believe the most reasonably likely worst case scenario faced by us
as a result of the Year 2000 issue is the possibility that reimbursement delays
caused by a failure of federal and state welfare programs responsible for
Medicare and Medicaid could adversely affect our tenants' cash flow, resulting
in their temporary inability to meet their obligations under our leases.
Depending upon the severity of any reimbursement delays and the financial
strength of any particular operator, the operations of our tenants could be
materially adversely affected, which in turn could have a material adverse
effect on our results of operations.

         In September 1998, the General Accounting Office reported that the
Health Care Financing Administration, which runs Medicare, is behind schedule in
taking steps to deal with the Year 2000 issue and that it is highly unlikely
that all of the Medicare systems will be compliant in time to ensure the
delivery of uninterrupted benefits and services into the year 2000. The General
Accounting Office also reported in November 1998 that, based upon its survey of
the states, the District of Columbia and three territories, less than 16% of the
automated systems used by state and local government to administer Medicaid are
reported to be Year 2000 compliant. We do not know at this time whether there
will in fact be a disruption of Medicare or Medicaid reimbursements to our
lessees and mortgagors and we are therefore unable to determine at this time
whether the Year 2000 issue will have a material adverse effect on us or its
future operations.

Merger Properties

         As of November 4, 1999, the merger with American Health Properties was
completed. The operations of that company will be transferred to our own systems
prior to December 31, 1999. (See Status of Year 2000 Issues with HCPI's Own
Information Technology Systems and Non-IT Systems for a discussion of our Y2K
readiness.)

         American Health Properties had conducted Year 2000 compliance of their
lessees and operators and concluded that their lessees would be compliant. In
addition, the management companies that manage their multi-tenant medical office
buildings represented to them that they had implemented extensive Year 2000
compliance programs. To the best of our knowledge, we believe that such lessees
and multi-tenant buildings will be Year 2000 compliant.

Contingency Plans

         If there are severe disruptions in our cash flow as a result of
disruptions in our tenants' or mortgagors' cash flow, we may be forced to slow
our investment activity, or seek additional liquidity from our lenders.

         Readers are cautioned that most of the statements contained in the
"Year 2000 Issue" paragraphs are forward looking and should be read in
conjunction with HCPI's disclosures under the heading "Cautionary Language
Regarding Forward Looking Statements" set forth below.

Cautionary Language Regarding Forward Looking Statements

         Statements in this Quarterly Report that are not historical factual
statements are "forward looking statements" within the meaning of the Private
Securities Litigation Reform Act of 1995. The statements include, among other
things, statements regarding the intent, belief or expectations of HCPI and its
officers and can be identified by the use of terminology such as "may", "will",
"expect", "believe", "intend", "plan", "estimate", "should" and other comparable
terms or the negative thereof. In addition, HCPI, through its senior management,
from time to time makes forward looking oral and written public statements
concerning HCPI's expected future operations and other developments.
Shareholders and investors are cautioned that, while forward looking statements
reflect HCPI's good faith beliefs and best judgment based upon current
information, they are not guarantees of future performance and are subject to
known and unknown risks and uncertainties. Actual results may differ materially
from the expectations contained in the forward looking statements as a result of
various factors. Such factors include:

   (a)    Legislative, regulatory, or other changes in the healthcare industry
          at the local, state or federal level which increase the costs of or
          otherwise affect the operations of HCPI's lessees;

   (b)    Changes in the reimbursement available to HCPI's lessees and
          mortgagors by governmental or private payors, including changes in
          Medicare and Medicaid payment levels, availability and cost of third
          party insurance coverage; such as those contained in the Balanced
          Budget Act of 1997, which contains extensive changes to the Medicare
          and Medicaid programs intended to significantly reduce the projected
          amount of increase in Medicare spending. In particular, the Budget
          Act's limitation on reimbursable costs and reductions in payment
          incentives and capital related payments as well as the recently
          implemented prospective payment system, which is expected to decrease
          reimbursements to skilled nursing homes, may have an adverse effect on
          the operator revenues at the Company's rehabilitation and long-term
          acute care facilities;

   (c)    Competition for lessees and mortgagors, including with respect to new
          leases and mortgages and the renewal or rollover of existing leases;

   (d)    Competition for the acquisition and financing of health care
          facilities;

   (e)    The ability of HCPI's lessees and mortgagors to operate HCPI's
          properties in a manner sufficient to maintain or increase revenues and
          to generate sufficient income to make rent and loan payments;

   (f)    Risks associated with HCPI's multi-tenant medical office buildings,
          such as lower than expected occupancy levels, a downturn in market
          lease rates for medical office space or higher than expected costs
          associated with the maintenance and operation of the such facilities;

   (g)    Changes in national or regional economic conditions, including changes
          in interest rates and the availability and cost of capital to HCPI;
          and

   (h)    General uncertainty inherent in the Year 2000 issue, particularly the
          uncertainty of the Year 2000 readiness of third parties who are
          material to HCPI's business, such as public or private healthcare
          reimbursers, over whom HCPI has no control with the result that HCPI
          cannot ensure its ability to timely and cost-effectively avert or
          resolve problems associated with the Year 2000 issue that may affect
          its operations and business.

DISCLOSURES ABOUT MARKET RISK



                                      -19-
<PAGE>   21

         HCPI is exposed to market risks related to fluctuations in interest
rates on its mortgage loans receivable and on its debt instruments. The
following discussion and table presented below are provided to address the risks
associated with potential changes in HCPI's interest rate environment.

         HCPI provides mortgage loans to operators of healthcare facilities in
the normal course of business. All of the mortgage loans receivable have fixed
interest rates or interest rates with periodic fixed increases. Therefore, the
mortgage loans receivable are all considered to be fixed rate loans, and the
current interest rate (the lowest rate) is used in the computation of market
risk provided in the table below if material.

         HCPI generally borrows on its short-term bank lines of credit to
complete acquisition transactions. These borrowings are then repaid using
proceeds from subsequent long-term debt and equity offerings. HCPI may also
assume mortgage notes payable already in place as part of an acquisition
transaction. As of September 30, 1999, HCPI has two mortgage notes payable with
variable interest rates and the remaining mortgage notes payable have fixed
interest rates or interest rates with fixed periodic increases. HCPI's senior
notes and convertible debt are at fixed rates. The variable rate loans are at
interest rates at or below the current prime rate of 8.25%, and fluctuations are
tied to the prime rate or to a rate currently below the prime rate.

         Fluctuation in the interest rate environment will not impact HCPI's
future earnings and cash flows on its fixed rate debt until that debt matures
and must be replaced or refinanced. Interest rate changes will affect the fair
value of the fixed rate instruments. Conversely, changes in interest rates on
variable rate debt would change the future earnings and cash flows of HCPI, but
not affect the fair value on those instruments. Assuming a one percentage point
increase in the interest rate related to the variable rate debt including the
mortgage notes payable and the bank lines of credit, and assuming no change in
the outstanding balance as of September 30, 1999, interest expense for the
coming year would increase by approximately $1,229,000. Approximately 20% of the
increase in interest expense related to the bank lines of credit, or $246,000,
would be capitalized into construction projects.

         The principal amount and the average interest rates for the mortgage
loans receivable and debt categorized by the final maturity dates are presented
in the table below. Certain of the mortgage loans receivable and certain of the
debt securities, excluding the convertible debentures, require periodic
principal payments prior to the final maturity date. The fair value estimates
for the mortgage loans receivable are based on the estimates of management and
on rates currently prevailing for comparable loans. The fair market value
estimates for debt securities are based on discounting future cash flows
utilizing current rates offered to HCPI for debt of the same type and remaining
maturity.

                         DIRECTORS STOCK INCENTIVE PLAN


        Health Care Property Investors, Inc., a Maryland corporation (the
"Company"), had adopted by written consent the Second Amended and Restated
Directors Stock Incentive Plan (the "Plan"), effective as of April 23, 1997.

        In order to amend the Plan to reflect certain changes with respect to
the exercisability of options subsequent to a Change of Control, this Amendment
to the Plan has been adopted by a written consent of the Board of Directors of
the Company, effective as of November 3, 1999.

        1.     Section 6(e) of the Plan shall be amended and restated in its
entirety as follows:

               "(e) Options which have been granted but have not yet otherwise
become exercisable shall become exercisable immediately if, after a Change of
Control, a Director is (a) removed from the Board during the Director's term of
election that included the date of a Change of Control, or (b) not re-elected
immediately following expiration of the term that included the date of a Change
of Control. In addition, notwithstanding any other provision of this Plan, (i)
with respect to grants of Options on or after November 3, 1999 which are
outstanding on the date of a Change of Control, such Options, to the extent then
exercisable (including Options which become exercisable by a Change of Control),
shall not expire until the later of the date specified in the Director's stock
option agreement or the third anniversary after the date the Director ceases to
be a Director and (ii) with respect to Options which are outstanding as of

                               SECOND AMENDMENT TO
                    THE HEALTH CARE PROPERTY INVESTORS, INC.
                           SECOND AMENDED AND RESTATED
                       DIRECTOR DEFERRED COMPENSATION PLAN


        Health Care Property Investors, Inc., a Maryland corporation (the
"Company"), had adopted by written consent the Second Amended and Restated
Director Deferred Compensation Plan (the "Plan") and the First Amendment to the
Plan, both effective as of the termination of the Retirement Plan for Outside
Directors (the "Retirement Plan").

        In order to clarify certain provisions of the Plan and to expressly
provide for the administration of the Plan by the Compensation Committee of the
Board of Directors (the "Committee"), this Amendment to the Plan has been
adopted by a written consent of the Committee, effective as of November 3, 1999.

        1.     Section 3(f)(ii) shall be amended and restated as follows:

               "(ii) Participants may at any time file with the Company an
election to reallocate all or any portion of amounts credited to Plan Accounts
from Interest Rate Accounts to Stock Credit Accounts or vice versa. Such
reallocation shall be made by the delivery to the Company by the Participant of
a written election, substantially in the form of Exhibit A-3 attached, executed
by the Participant which shall become effective (1) only upon the approval of
the Committee in its sole discretion and (2) as of the first day of the fiscal
quarter beginning immediately following the date on which the Committee approves
such election or the beginning of such later fiscal quarter as may be designated
in the notice. In reallocating any amounts from Interest Rate Accounts to Stock
Credit Accounts or vice versa, the number of Common Stock units and the value of
the Common Stock units to be reallocated shall be determined based upon the
Average Closing Price of the Common Stock determined as of the effective date of
the reallocation."

        2.     Section 9 shall be renumbered Section 10 and a new Section 9
shall be added as follows:

               "9.  Administration.

               (a)  Committee Duties and Powers. The Committee shall conduct the
general administration of the Plan in accordance with the Plan and shall have
all necessary power and authority to carry out that function. Among its
necessary powers and duties are the following:

                    (i)       To delegate all or part of its function to others
        and to revoke any such delegation.


<PAGE>   2

                    (ii)      To interpret the Plan for purpose of the
        administration and application of the Plan, in a manner not inconsistent
        with the Plan or applicable law and to amend or revoke any such
        interpretation.

                    (iii)     To determine questions of eligibility of
        Participants and their entitlement to benefits.

               (b)  Limitations Upon Powers. The Plan shall be uniformly and
consistently administered, interpreted and applied with regard to all
Participants in similar circumstances. The Plan shall be administered,
interpreted and applied fairly and equitably and in accordance with the
specified purposes of the Plan.

               (c)  Indemnification. The Company shall pay or reimburse
Committee members for all expenses incurred by such Committee members in, and
shall indemnify and hold them harmless from, all claims, liabilities and costs
(including reasonable attorneys' fees) arising out of the good faith performance
of their duties under the Plan."

                               FIRST AMENDMENT TO
                    THE HEALTH CARE PROPERTY INVESTORS, INC.
                           SECOND AMENDED AND RESTATED
                              STOCK INCENTIVE PLAN


        Health Care Property Investors, Inc., a Maryland corporation (the
"Company"), had adopted by written consent the Second Amended and Restated Stock
Incentive Plan (the "Plan"), effective as of April 23, 1997.

        In order to amend the Plan to reflect certain changes with respect to
the exercisability of options subsequent to a Change in Control, this Amendment
to the Plan has been adopted by a written consent of the Compensation Committee
of the Board of Directors of the Company, effective as of November 3, 1999.


        1.     Section 8(b) of the Plan shall be amended by replacing the first
sentence with the following sentences:

               "Despite the provisions of Section 8(a), upon a Change in Control
(as defined below) all Incentive Awards then outstanding under the Plan will be
fully vested and exercisable and all restrictions will immediately cease, unless
provisions are made in connection with such transaction for the continuance of
the Plan and the assumption or the substitution for such Incentive Awards of new
incentive awards covering the stock of a successor employer corporation, or a
parent or subsidiary thereof, with appropriate adjustments as to the number and
kind of shares and prices. In addition, (i) subject to the preceding sentence
with respect to grants of Options on or after November 3, 1999 which are
outstanding on the date of a Change in Control, such Options, to the extent then
exercisable (including Options which become exercisable by a Change in Control),
shall not expire until the later of the date specified in the Participant's
stock option agreement or the third anniversary after the date of the
Participant's termination of employment with the Company and (ii) all Options
outstanding as of November 3, 1999 with an exercise price which equals or
exceeds the Fair Market Value of the Common Stock as of November 3, 1999 shall
be amended, and are hereby amended, to provide that such Options continue to be
exercisable after a Change of Control pursuant to the terms set forth in the
preceding clause; provided, however, that in no event shall such Options be
exercisable more than ten (10) years from the Date of Grant. Furthermore, with
respect to Options granted before November 3, 1999 with an exercise price which
is less than the Fair Market Value of the Common Stock as of November 3, 1999,
the Committee may, in its sole discretion, amend any or all of such Options to
provide that the Options continue to be exercisable after a Change in Control
pursuant to the terms set forth in this Section 6(e)."

                           REVOLVING CREDIT AGREEMENT


               REVOLVING CREDIT AGREEMENT, dated as of November 3, 1999 (this
"Agreement"), among Health Care Property Investors, Inc., a Maryland corporation
(the "Company"), each of the banks identified on the signature pages hereof
(each, a "Bank" and, collectively, the "Banks"), The Bank of New York, as Agent
for the Banks (the "Agent") and as Issuing Bank, and Bank of America, N.A. and
Wells Fargo Bank, N.A., as Co-Documentation Agents, with BNY Capital Markets,
Inc., as Lead Arranger and Book Manager:

                              W I T N E S S E T H:

               WHEREAS, the Company has requested the Banks to lend up to
$207,000,000 to the Company on a revolving basis to refinance certain existing
indebtedness, to finance the acquisition of American Health Properties, Inc., a
Delaware corporation ("AHPI"), and for other general corporate purposes;

               NOW, THEREFORE, the parties hereby agree as follows:

                                   ARTICLE I.

                                   DEFINITIONS

        Section 1.1. Definitions.


               (a) Terms Generally. The definitions ascribed to terms in this
SECTION and elsewhere in this Agreement shall apply equally to both the singular
and plural forms of the terms defined. Whenever the context may require, any
pronoun shall include the corresponding masculine, feminine and neuter forms.
The words "include", "includes" and "including" shall be deemed to be followed
by the phrase "without limitation". The words "hereby", "herein", "hereof",
"hereunder" and words of similar import refer to this Agreement as a whole
(including any exhibits and schedules hereto) and not merely to the specific
section, paragraph or clause in which such word appears. All references herein
to Articles, Sections, Exhibits and Schedules shall be deemed references to
Articles and Sections of, and Exhibits and Schedules to, this Agreement unless
the context shall otherwise require. Except as otherwise expressly provided
herein, (i) all references to "dollars" or "$" shall be deemed references to the
lawful money of the United States of America, and (ii) any definition of or
reference to any agreement, instrument or other document herein shall be
construed as referring to such agreement, instrument or other document as from
time to time amended, supplemented or otherwise modified (subject to any
restrictions on such amendments, supplements or other modifications set forth
herein).

               (b) Accounting Terms. Except as otherwise expressly provided
herein, all terms of an accounting or financial nature shall be construed in
accordance with GAAP, as in effect from time to time; provided, however, that,
for purposes of determining compliance with any covenant set forth in SECTION
8.2(a), 8.2(b), 8.2(c), 8.2(d) or 8.3 which requires financial computations, if
any such change in GAAP would have a material effect on such computations, then
such terms shall be construed in accordance with GAAP as in effect on the date
of this

<PAGE>   6

Agreement applied on a basis consistent with the construction thereof applied in
preparing the Company's audited financial statements referred to in SECTION
6.1(h). In the event there shall occur a change in GAAP which but for the
foregoing proviso would affect the computation used to determine compliance with
any covenant set forth in SECTION 8.2(a), 8.2(b), 8.2(c) or 8.3 which requires
financial computations, the Company and the Banks agree to negotiate in good
faith in an effort to agree upon an amendment to this Agreement that will permit
compliance with such covenant to be determined by reference to GAAP as so
changed while affording the Banks the protection afforded by such covenant prior
to such change (it being understood, however, that such covenant shall remain in
full force and effect in accordance with its existing terms pending the
execution by the Company and the Banks of any such amendment).

               (c) Other Terms. The following terms shall have the meanings
ascribed to them below or in the Sections of this Agreement indicated below:

               "ABR Loans" shall mean Committed Loans which bear interest at a
rate based upon the Base Rate and in the manner set forth in SECTION 4.2.

               "Adverse Environmental Condition" shall mean any of the matters
referred to in clauses (i) or (ii) of the definition of Environmental Claim.

               "Affiliate" shall mean, with respect to any Person, any other
Person directly or indirectly controlling, controlled by, or under direct or
indirect common control with such Person. A Person shall be deemed to control
another Person if such first Person possesses, directly or indirectly, the power
to direct or cause the direction of the management and policies of such other
Person, whether through ownership of stock, by contract or otherwise.

               "Agent" shall have the meaning given to such term in the preamble
of this Agreement and shall also include any successor agent hereunder.

               "Agreement" shall have the meaning given to such term in the
preamble.

               "AHPI" shall have the meaning given to such term in the preamble.

               "AHPI Merger Documents" shall mean the Agreement and Plan of
Merger, dated as of August 4, 1999, between the Company and AHPI, and each
agreement, instrument or other document executed or delivered in connection
therewith.

               "Applicable Margin" shall mean the margin set forth in the
following chart applicable to the Pricing Level then in effect:

each of the conditions contained in SECTION 7.2, each of the Banks, severally

aggregate principal amount of outstanding Negotiated Rate Loans, (iii) the
aggregate principal amount of outstanding Competitive Bid Loans and (iv) the
aggregate Face Amount of issued and outstanding Letters of Credit may not exceed

<PAGE>   19

Bank shall make available to the Agent in immediately available funds at the
office of the Agent at its address set forth on the signature pages hereof, such
Bank's Pro Rata Share of the requested Committed Loans.

               (c) Upon receipt by the Agent of all such funds the Agent shall
disburse to the Company on the requested Borrowing Date the Committed Loans
requested in such Committed Loan Request. The Agent may, but shall not be
required to, advance on behalf of any Bank such Bank's Pro Rata Share of the
Committed Loans on a Borrowing Date unless such Bank shall have notified the
Agent prior to such Borrowing Date that it does not intend to make available its
Pro Rata Share of such Committed Loans on such date. If the Agent makes such
advance, the Agent shall be entitled to recover such amount on demand from the
Bank on whose behalf such advance was made, and if such Bank does not pay the
Agent the amount of such advance on demand, the Company shall promptly repay
such amount to the Agent. Until such amount is repaid to the Agent by such Bank

by the Agent. The Agent shall be entitled to recover from the Bank or the
Company, as the case may be, interest on the amount advanced by it for each day
from the Borrowing Date therefor until repaid to the Agent, at a rate per annum
equal to (i) in the case of the Bank, (1) the Federal Funds Rate, for the

        Section 2.3. Committed Notes. The Company's obligation to repay the
Committed Loans shall be evidenced by Committed Notes, one such Committed Note

initial Committed Loan and (iii) be stated to mature on the Termination Date as
such date may be extended hereunder and bear interest from its date until
maturity on the principal balance (from time to time outstanding thereunder)
payable at the rates and in the manner provided herein. Each Bank is authorized
to indicate upon the grid attached to its Committed Note all Committed Loans
made by it pursuant to this Agreement, interest elections and payments of
principal and interest thereon. Such notations shall be presumptive as to the
aggregate unpaid principal amount of all Committed Loans made by such Bank, and
interest due thereon, but the failure by any Bank to make such notations or the
inaccuracy or incompleteness of any such notations shall not affect the
obligations of the Company hereunder or under the Committed Notes.

        Section 2.4. Cancellation or Reduction of the Commitment. The Company
shall have the right, upon not less than three Business Days' written notice to
the Agent and upon payment of the Facility Fees accrued through the date of such
cancellation or reduction, with respect to the amount of the cancellation or
reduction, to cancel the Total Commitment in full or to reduce the amount

long as


                                       15
<PAGE>   20

any Loan or Letter of Credit remains outstanding or any Reimbursement Obligation
remains unpaid; and provided, further, that the amount of any partial reduction
in the Total Commitment shall not exceed the remainder of (i) the Total
Commitment on such date minus (ii) the sum of the aggregate outstanding
principal amount of all Committed Loans, Negotiated Rate Loans and Competitive
Bid Loans on such date plus (ii) the aggregate Face Amount of all issued and
outstanding Letters of Credit on such date. Partial reductions of the Total
Commitment shall be in the amount of $5,000,000 or in integral multiples of
$1,000,000 in excess thereof (or, if the aggregate outstanding amount of all
Loans is less than $5,000,000, then all of such lesser amount). All such
cancellations or reductions shall be permanent.

        Section 2.5. Negotiated Rate Loans. On the terms and subject to the
conditions of this Agreement, each Bank, severally and for itself alone, may
(but is not obligated to) make one or more Negotiated Rate Loans to the Company

Termination Date in amounts determined as indicated in the Negotiated Rate
Confirmation and for a term that, for each Negotiated Rate Loan, is not less
than one day nor more than 270 days from the date of funding of such Negotiated
Rate Loan as provided in SECTION 2.7; provided that the sum of (i) the aggregate
principal amount of all outstanding Loans plus (ii) the aggregate Face Amount of
all issued and outstanding Letters of Credit shall not at any time exceed the
then Total Commitment.

        Section 2.6. Procedure for Negotiated Rate Loans. The Company may, from
time to time, approach one or more of the Banks to determine whether such Bank
or Banks will make one or more Negotiated Rate Loans. The Company and any Bank
or Banks shall, if each of them in their sole discretion elects to do so, agree
to enter into one or more Negotiated Rate Loans as part of such proposed
Negotiated Rate Borrowing on mutually agreed-upon terms and notify the Agent by
delivering a written Negotiated Rate Confirmation from the Company and the Bank
or Banks proposing to make Negotiated Rate Loans before 12:30 p.m. (New York
City time) on the date of the funding of such Negotiated Rate Loan, which shall
be a Business Day (the "Negotiated Rate Funding Date"). Such Negotiated Rate
Confirmation shall specify the amount of each Negotiated Rate Loan that such
Bank or Banks will make as part of such proposed Negotiated Rate Borrowing
(which amounts may, subject to the proviso in SECTION 2.5, exceed each such
Bank's Commitment), the Negotiated Rate Funding Date, the date or dates of
maturity thereof, which date or dates may not occur after the Termination Date,
the rate or rates of interest applicable thereto and all other terms thereof.
Each Negotiated Rate Loan shall be made pursuant to a Negotiated Rate
Confirmation. In lieu of delivering the written Negotiated Rate Confirmation
described above, the Company may give the Agent telephonic notice of any
Negotiated Rate Borrowing by the time required under this clause (a), provided
that such telephonic notice shall be confirmed by delivery of a written
Negotiated Rate Confirmation to the Agent by no later than 2:00 p.m., New York
City time, on the date of such telephonic notice.

        Section 2.7. Funding of Negotiated Rate Loans. No later than 2:00 p.m.

of the Agent at its address set forth on the signature pages hereof the
Negotiated Rate Loan, if any, to be made by such Bank as part of the Negotiated
Rate Borrowing to be made on such date in the manner provided above. Upon
receipt by the Agent of all such funds, the Agent shall disburse to the Company
on such date such Negotiated Rate Loan in like funds at the Company's account
specified in the relevant


                                       16
<PAGE>   21

Negotiated Rate Confirmation. The Agent may, but shall not be required to,
advance on behalf of any Bank such Bank's Negotiated Rate Loan on a Borrowing
Date unless such Bank shall have notified the Agent prior to such Borrowing Date
that it does not intend to make available such Negotiated Rate Loan on such
date. If the Agent makes such advance, the Agent shall be entitled to recover
such amount on demand from the Bank on whose behalf such advance was made, and
if such Bank does not pay the Agent the amount of such advance on demand, the
Company shall promptly repay such amount to the Agent. Until such amount is
repaid to the Agent by such Bank or the Company, such advance shall be deemed
for all purposes to be a Negotiated Rate Loan made by the Agent. The Agent shall
be entitled to recover from the Bank or the Company, as the case may be,
interest on the amount advanced by it for each day from the Borrowing Date
therefor until repaid to the Agent, at a rate per annum equal to (i) in the case
of the Bank, (1) the Federal Funds Rate, for the five-day period beginning on
the Borrowing Date, and (2) the applicable rate on the Loans made on the
Borrowing Date, for the period beginning on the sixth day after the Borrowing
Date, and (ii) in the case of the Company, the applicable rate on the Loans made
on the Borrowing Date.

        Section 2.8. Negotiated Rate Notes. The Negotiated Rate Loans of each
Bank shall be evidenced by a Negotiated Rate Note payable to the order of each
Bank. The Negotiated Rate Note of each Bank shall (i) be in the principal amount
of $207,000,000, or such amount less than $207,000,000 as the Company and such
Bank may agree, (ii) be dated not later than the date of the initial Negotiated
Rate Confirmation relating to a Negotiated Rate Loan made by such Bank and (iii)
be stated to mature on the Termination Date as such date may be extended
hereunder and bear interest from its date until maturity on the principal
balance (from time to time outstanding thereunder) payable at the rates and in
the manner provided herein and in the applicable Negotiated Rate Confirmations.
Each Bank is authorized to indicate upon the grid attached to its Negotiated
Rate Note all Negotiated Rate Loans made by it pursuant to this Agreement,
interest elections and payments of principal and interest thereon. Such
notations shall be presumptive as to the aggregate unpaid principal amount of
all Negotiated Rate Loans made by such Bank, and interest due thereon, but the
failure by any Bank to make such notations or the inaccuracy or incompleteness
of any such notations shall not affect the obligations of the Company hereunder
or under the Negotiated Rate Notes.

        Section 2.9. Competitive Bid Loans. On the terms and subject to the
conditions of this Agreement, from time to time on or after the Effective Date
and prior to the Termination Date, the Company may (but is not obligated to)
make requests for Competitive Bids for Competitive Bid Loans and may (but is not

Bid Loan.

               (c) Acceptance/Rejections of Competitive Bids. The Agent shall

Loan unless such Competitive Bid Loan is in the amount of $5,000,000 or in
integral multiples of $1,000,000 in excess thereof; provided, further, that if a
Competitive Bid Loan must be in an amount less than $5,000,000 because of the
provisions of clause (iv) above, such Competitive Bid Loan may be for an amount
of $1,000,000 or any integral multiple in excess thereof, and in calculating the
pro rata allocation of acceptances of portions of multiple Competitive Bids at a
particular Competitive Bid Rate pursuant to clause (iv) the amounts shall be
rounded to integral multiples of $1,000,000 in a manner determined by the
Company. A notice given by the Company pursuant to this paragraph shall be
irrevocable.

               (d) Competitive Bid Confirmation. The Agent shall promptly notify
each bidding Bank by facsimile whether or not its Competitive Bid has been
accepted (and, if so, the amount and Competitive Bid Rate so accepted), and each
successful bidder will thereupon become bound, on the terms and subject to the
conditions of this Agreement, to make the Competitive Bid Loan in respect of
which its Competitive Bid has been accepted.

               (e) Competitive Bids by the Agent. If the Agent shall elect to
submit a Competitive Bid in its capacity as a Bank, it shall submit such
Competitive Bid directly to the Company at least one quarter of an hour earlier
than the time by which the other Banks are required to submit their Competitive
Bids to the Agent pursuant to paragraph (b) of this SECTION.

        Section 2.11. Funding of Competitive Bid Loans. No later than 2:00 p.m.,
New York City time, on the relevant Borrowing Date, each Bank will make
available to the Agent in dollars and immediately available funds at the office
of the Agent at its address set forth on the signature pages hereof, each
Competitive Bid Loan, if any, to be made by such Bank as part of the Competitive
Bid Borrowing to be made on such date in the manner provided above. Upon receipt
by the Agent of all such funds, the Agent shall disburse to the Company on such
date such Competitive Bid Loan in like funds at the Company's account specified
in the relevant Competitive Bid Request. The Agent may, but shall not be
required to, advance on behalf of any Bank such Bank's Competitive Bid Loan on a
Borrowing Date unless such Bank shall have notified the Agent prior to such
Borrowing Date that it does not intend to make available such Competitive Bid
Loan on such date. If the Agent makes such advance, the Agent shall be entitled
to recover such amount on demand from the Bank on whose behalf such advance was
made, and if such Bank does not pay the Agent the amount of such advance on
demand, the Company shall promptly repay such amount to the Agent. Until such
amount is repaid to the Agent by such Bank or the Company, such advance shall be
deemed for all purposes to be a Competitive Bid Loan made by the Agent. The
Agent shall be entitled to recover from the Bank or the Company, as the case may
be, interest on the amount advanced by it for each day from the Borrowing Date
therefor until repaid to the Agent, at a rate per annum equal to (i) in the case
of the Bank, (1) the Federal Funds Rate, for the five-day period beginning on
the Borrowing Date, and (2) the applicable rate on the Loans made on the
Borrowing Date, for the period beginning on the sixth day after the Borrowing
Date, and (ii) in the case of the Company, the applicable rate on the Loans made
on the Borrowing Date.

        Section 2.12. Competitive Bid Notes. The Competitive Bid Loans of each
Bank shall be evidenced by a Competitive Bid Note payable to the order of each
Bank. The Competitive Bid Note of each Bank shall (i) be in the principal amount
of $207,000,000, (ii) be dated not later


                                       19
<PAGE>   24

than the date of the initial Competitive Bid Loan made by such Bank and (iii) be
stated to mature on the Termination Date as such date may be extended hereunder
and bear interest from its date until maturity on the principal balance (from
time to time outstanding thereunder) payable at the rates and in the manner
provided herein. Each Bank is authorized to indicate upon the grid attached to
its Competitive Bid Note all Competitive Bid Loans made by it pursuant to this
Agreement, interest elections and payments of principal and interest thereon.
Such notations shall be presumptive as to the aggregate unpaid principal amount
of all Competitive Bid Loans made by such Bank, and interest due thereon, but
the failure by any Bank to make such notations or the inaccuracy or
incompleteness of any such notations shall not affect the obligations of the
Company hereunder or under the Competitive Bid Notes.

        Section 2.13. Certain Fees. (a) The Company shall pay to the Agent for
the pro rata account of the Banks during the period from and including the
Effective Date through but excluding the Termination Date a fee (the "Facility
Fee") equal to the Facility Fee Rate per annum (on the basis of a 360-day year
for the actual number of days involved) on the daily average amount of the Total
Commitment during the quarter with respect to which such Facility Fee is being
paid. Such fee shall be payable in arrears on the last day of each calendar
quarter, commencing on the first such date after the Effective Date, on any date
that the Total Commitment is canceled or reduced pursuant to SECTION 2.4 (but
only with respect to the amount of such cancellation or reduction) and on the
Termination Date.

               (b) The Company shall pay to the Agent for the pro rata account
of the Banks during the period from and including the Effective Date through but
excluding the Termination Date, a fee (the "Utilization Fee") equal to (i)
0.125% per annum (on the basis of a 360-day year for the actual number of days
involved) on the daily amount during such period of the sum of (1) the aggregate
unpaid principal amount of all Committed Loans and the aggregate Face Amount of
all issued and outstanding Letters of Credit plus (2) the aggregate unpaid
principal amount of all committed loans under the 364-Day Revolving Credit
Agreement, dated as of November 3, 1999, among the Borrower, the banks named
therein and The Bank of New York, as agent, provided that such sum is greater
than 50% of the sum of the Total Commitments on such day and the total
commitments to make committed or similar loans under such 364-Day Revolving
Credit Agreement on such day, multiplied by (ii) a fraction, the numerator of
which is the sum of the aggregate unpaid principal amount on such day of all
Committed Loans and the aggregate Face Amount on such day of all issued and
outstanding Letters of Credit and the denominator of which is the sum of items
(1) and (2) above. Such fee shall be payable in arrears on the last day of each
calendar quarter, commencing on the first such date after the date hereof, and
on the Termination Date.

               (c) The Company shall pay to each of the Agent and the Banks, for
its account, fees payable in the amounts and at the times separately agreed upon
between the Company and the Agent or such Bank, as the case may be.

        Section 2.14. Optional Prepayment. The Company shall have the right, on
not less than three Business Days' written notice to the Agent, in the case of
Eurodollar Loans, and on not less than one Business Day's written notice to the
Agent, in the case of ABR Loans, Negotiated Rate Loans and Competitive Bid
Loans, to prepay Loans that, in the case of all Loans other than Negotiated Rate
Loans, bear interest on the same basis and having the same Interest Periods, if


                                       20
<PAGE>   25

any, or terms, as the case may be, in whole or in part, without premium or
penalty, in the aggregate principal amount of $1,000,000 or in integral
multiples of $250,000 in excess thereof (or, if the unpaid principal amount of
such Loan is less than $1,000,000, then all of such lesser amount), together
with accrued interest on the principal being prepaid to the date of prepayment,
the amounts required by SECTION 5.3 and, in the case of Negotiated Rate Loans,
such other compensation as may be agreed to by the Company and the Bank making
such Negotiated Rate Loan and as to which the Company and such Bank shall have
promptly notified the Agent; provided that the Company shall not have the right
to prepay any Negotiated Rate Loan or any Competitive Bid Loan without the prior
written consent of the Bank making such Negotiated Rate Loan or such Competitive
Bid Loan, as the case may be. Subject to the terms and conditions hereof,
prepaid Loans may be reborrowed.

                                  ARTICLE III.

                                LETTERS OF CREDIT

        Section 3.1. Letters of Credit. Subject to the terms and conditions
hereof, the Issuing Bank shall issue letters of credit (each, a "Letter of
Credit") for the account of the Company.

               (a) The commitment hereunder of the Issuing Bank to issue or
renew Letters of Credit (the "Letter of Credit Commitment") shall be equal to
the lesser of (i) $50,000,000 and (ii) the difference between the Total
Commitment less the sum of the aggregate outstanding principal amount of all
Loans on such date.

               (b) The Letters of Credit (i) shall have an aggregate Face Amount
not in excess of the Letter of Credit Commitment, (ii) may, at the sole option
of the Issuing Bank, be renewable if so requested by the Company using the form
for such request then in general use by the Issuing Bank and (iii) shall have an
expiration date no later than the earlier of (1) 365 days after the date of
issuance thereof and (2) five Business Days prior to the Termination Date.

               (c) The Company shall, no later than 2:00 p.m., New York City
time, on the date not less than three Business Days (or such lesser period to
which the Issuing Bank may agree in writing) before the date on which issuance
or renewal of a Letter of Credit is desired, give the Agent written notice
substantially in the form of EXHIBIT L (effective upon receipt) (a "Letter of
Credit Notice") specifying the date on which each Letter of Credit is to be
issued or renewed, the requested expiration date thereof and the stated amount
thereof, and attaching a proposed form of such letter of credit or other
applicable form accompanied by a completed form of application for issuance or
renewal of a letter of credit, using such standard form as shall then be in
general use by the Issuing Bank. Upon receipt of such notice, the Agent shall
notify the Issuing Bank and each Bank of the contents thereof. Notwithstanding
the foregoing, in lieu of delivering the written notice described above, the
Company may give the Agent and the Issuing Bank telephonic notice of any request
for the issuance or renewal of a Letter of Credit by the time required under
this clause (c), provided, further, that such telephonic notice shall be
confirmed by delivery of a written Letter of Credit Notice to the Agent and the
Issuing Bank by no later than 4:00 p.m., New York City time, on the date of such
telephonic notice.


                                       21
<PAGE>   26

               (d) Upon the date of issuance or renewal of each Letter of
Credit, the Issuing Bank shall be deemed, without further action by any party
hereto, to have sold to each Bank, and each Bank hereby irrevocably agrees to
purchase, and each Bank shall be deemed, without further action by any party
hereto, to have purchased, from the Issuing Bank, an undivided and continuing
participation in such Letter of Credit, in accordance with such Bank's Pro Rata
Share.

               (e) Upon receipt from the beneficiary of any Letter of Credit or
any demand for payment under such Letter of Credit, the Issuing Bank shall
promptly notify the Company and the Agent as to the amount paid or to be paid as
a result of such demand and the respective payment date.

               (f) Each Bank shall, upon request by the Issuing Bank (with a
copy to the Agent), remit to the Issuing Bank, through the Agent, such Bank's
share (as determined in accordance with SECTION 3.1(d) above) of the payment
made by the Issuing Bank together with interest thereon for each day from the
day of demand through the day of payment at a rate equal to the Federal Funds
Rate, changing as and when said rate shall change, plus, for each day from the
day three Business Days after such demand through the day of payment, two
percent. If the Issuing Bank shall have made such request to any Bank prior to
12:00 noon, New York City time, on a Business Day, such payment shall be made by
each Bank no later than 2:00 p.m., New York City time, on such Business Day,
otherwise such payment shall be made no later than 2:00 p.m., New York City
time, on the next Business Day.

               (g) The Company shall, not later than 2:00 p.m., New York City
time, on the date of payment of each drawing, reimburse the Issuing Bank,
through the Agent, for any amounts paid by the Issuing Bank under any Letter of
Credit. The Issuing Bank shall promptly remit to each Bank, through the Agent,
such Bank's share (as determined in accordance with SECTION 3.1(d)) of any
payment received by the Issuing Bank to the extent that such Bank has reimbursed
the Issuing Bank in accordance with SECTION 3.1(f). To the extent that the
Company does not reimburse the Issuing Bank, by means of payment pursuant to
this clause (g) or by means of Loans issued pursuant to SECTION 3.1(h), for any
payment by the Issuing Bank under any Letter of Credit on the date of such
payment, such amounts not reimbursed shall accrue interest, payable on demand,
at the rate per annum (on the basis of a 365-day year for the actual number of
days involved) equal to the sum of (i) 2% per annum and (ii) the rate of
interest then applicable to ABR Loans, changing as and when said rate shall
change.

               (h) The Company may request that the Banks make a Committed Loan
in order to pay its Reimbursement Obligation in respect of any payment of each
drawing under any Letter of Credit. To the extent that the Company has not
otherwise paid such Reimbursement Obligation on the date of any such drawing,
the Company shall be deemed to have given a timely notice of request for Loans
to be made on such day as ABR Loans in an aggregate amount of such Reimbursement
Obligation; such Loans, if made consistently with the provisions of this
Agreement, shall be deemed to have been made on the date of such drawing. On the
day that Loans are to be made in order to pay such Reimbursement Obligation,
each Bank shall, subject to and in accordance with the terms and conditions of
this Agreement (including satisfaction of the conditions set forth in ARTICLE
VII hereof), make a Loan, the proceeds of which shall be applied to such
Reimbursement Obligation; provided, however, that such Loan may be in amounts
less than the minimum aggregate principal amount or in amounts other than in
multiples of $100,000


                                       22
<PAGE>   27

in excess thereof as required by SECTION 2.2(a); and provided, further, that,
with respect to such Loan, such Bank shall be required to make available to the
Issuing Bank under SECTION 2.2(b) only an amount equal to the difference, if
any, between the amount of such Loan and the amount remitted through the Agent
to the Issuing Bank pursuant to SECTION 3.1(f). Nothing in this paragraph (h)
shall limit each Bank's irrevocable obligations with respect to participations
in each Letter of Credit pursuant to this SECTION.

               (i) The Company shall pay to the Agent for the account of each
Bank a letter of credit fee (the "Letter of Credit Fee") on such Bank's share
(as determined in accordance with SECTION 3.1(d)) of each Letter of Credit in
the daily average undrawn Face Amount of such Letter of Credit for the period
from and including the date of issuance thereof to and including the date of
expiration or termination thereof at a rate per annum (on the basis of a 360-day
year for the actual number of days involved) equal to the Applicable Margin,
such fee shall be payable in arrears on the last day of each calendar quarter
and on the date of expiration of such Letter of Credit; provided that if any
such day is not a Business Day, such fee shall be payable on the next preceding
Business Day.

               (j) The obligations of the Company under this SECTION shall be
unconditional and irrevocable and shall be paid strictly in accordance with the
terms of this Agreement under all circumstances, including circumstances such
as: (i) any lack of validity or enforceability of any Letter of Credit or any
other Credit Document; (ii) the existence of any claim, set-off, defense or
other right that the Company or any other Person may have at any time against
any beneficiary or transferee of any Letter of Credit (or any Persons for whom
any such beneficiary or transferee may be acting), the Issuing Bank, any Bank or
any other Person, whether in connection with this Agreement, the transactions
contemplated hereby or any unrelated transaction; (iii) any draft, certificate,
statement or other document presented under any Letter of Credit proving to be
forged, fraudulent, invalid or insufficient in any respect of any statement
therein being untrue or inaccurate in any respect; (iv) payment to the
beneficiary of such Letter of Credit by the Issuing Bank under any Letter of
Credit against presentation of a draft or certificate that does not comply with
the terms of such Letter of Credit, or payment to the beneficiary of such Letter
of Credit by the Issuing Bank under the Letter of Credit in any other
circumstances in which conditions to payment are not met, except any such
payment resulting solely from the gross negligence or willful misconduct of the
Issuing Bank; or (v) any other event, condition or circumstance whatever,
whether or not similar to any of the foregoing. The Company bears the risk of,
and none of the Issuing Bank, any of its directors, officers, employees or
agents, the Agent or any Bank shall be liable or responsible for, any of the
foregoing matters, the use that may be made of any Letter of Credit or acts or
omissions of the beneficiary or any transferee in connection therewith.

               (k) On each day during the period commencing with the issuance by
the Issuing Bank of any Letter of Credit and until such Letter of Credit shall
have expired or been terminated, the Commitment of each Bank shall be deemed to
be utilized for all purposes hereof (including SECTION 2.4) in an amount equal
to such Bank's share (as determined in accordance with SECTION 3.1(d)) of the
then Face Amount of such Letter of Credit; provided, however, that for the
purpose of determining whether any requested Loan or Letter of Credit would
exceed the Total Commitment if made, on each day during the period commencing
with the giving of notice by the Company to the Agent and the Issuing Bank of a
requested Letter of Credit pursuant to


                                       23
<PAGE>   28

SECTION 3.1(c), the Commitment of each Bank shall be deemed to be utilized in an
amount equal to such Bank's Commitment with respect to the then Face Amount of
such Letter of Credit.

               (l) The issuance and renewal by the Issuing Bank of each Letter
of Credit shall, in addition to the conditions set forth in ARTICLE VII, be
subject to the conditions precedent that such Letter of Credit shall be in such
form as shall be satisfactory to the Issuing Bank in its reasonable discretion
and that the Company shall have executed and delivered such other agreements,
instruments and other documents relating to such Letter of Credit as the Issuing
Bank shall have reasonably requested.

               (m) If, at any time, after the Issuing Bank has made payment on a
demand under a Letter of Credit and has received from any Bank such Bank's share
of such payment, and the Issuing Bank receives any payment or makes any
application of funds on account of the Company's Reimbursement Obligations under
such Letter of Credit arising from such payment, the Issuing Bank will pay to
the Agent, for the account of such Bank, such Bank's share (as determined in
accordance with SECTION 3.1(d)) of such payment.

               (n) If any amount received by the Issuing Bank on account of any
Letter of Credit or any Reimbursement Obligation shall be avoided, rescinded or
otherwise returned or paid over by the Issuing Bank for any reason at any time,
whether before or after the termination of this Agreement (or the Issuing Bank
believes in good faith that such avoidance, rescission, return or payment is
required, whether or not such matter has been adjudicated), each Bank shall,
promptly upon notice from the Issuing Bank, pay over to the Agent for the
account of the Issuing Bank its share (as determined in accordance with SECTION
3.1(d)) of such amount, together with its Pro Rata Share of any interest or
penalties payable with respect thereto.

               (o) In the event that the obligations of any Bank to make Loans
or of the Issuing Bank to issue or renew Letters of Credit terminates upon the
occurrence of an Event of Default or otherwise, upon such termination, the
Company shall, prior to the Termination Date, either (i) cause all Letters of
Credit to be returned to the Issuing Bank for cancellation or (ii) deposit with
the Issuing Bank an amount of cash equal to the sum of the Face Amount of all
Letters of Credit not so returned to the Issuing Bank upon such termination. The
Issuing Bank shall hold funds so deposited for the ratable benefit of the Banks
as collateral against the obligation of the Banks to pay such Letters of Credit
in the event of any draw with respect hereto and the obligation of the Company
to pay such Reimbursement Obligations. The Issuing Bank shall return to the
Company any amounts deposited with it pursuant to this clause (o) promptly upon
the expiration or cancellation of each Letter of Credit and the payment of each
Reimbursement Obligation with respect to which such funds were deposited.

               (p) Notwithstanding any other provision hereof, each Bank hereby
agrees that its obligation to participate in each Letter of Credit issued or
renewed in accordance herewith, its obligation to make the payments specified in
this SECTION, and the right of the Issuing Bank to receive such payments in the
manner specified therein are each absolute, irrevocable and unconditional and
shall not be affected by any event, condition or circumstance whatsoever. The
failure of any Bank to make any such payment shall not relieve any other Bank of
its funding obligation hereunder on the date due, but no Bank shall be
responsible for the failure of any other Bank to meet its funding obligations
hereunder.

                  INTEREST, METHOD OF PAYMENT, CONVERSION, ETC.

        Section 4.1. Procedure for Interest Rate Determination. (a) Unless the
Company shall request in a Committed Loan Request or in a Conversion/Continuance
Request that the Committed Loans (or portions thereof) bear interest as
Eurodollar Loans, the Committed Loans shall bear interest as ABR Loans.

               (b) Each Negotiated Rate Loan shall bear interest at the rate per
annum and subject to change or adjustment, if any, as agreed to by the Company
and the Bank making such Negotiated Rate Loan and as set forth in a Negotiated
Rate Confirmation.

               (c) Each Competitive Bid Loan shall bear interest at the
Competitive Bid Rate applicable to such Competitive Bid Loan.

        Section 4.2. Interest on ABR Loans and Competitive Bid Loans. (a)
Interest on ABR Loans. Each ABR Loan shall bear interest from the date of such
ABR Loan until maturity thereof or until such ABR Loan is repaid, or the
beginning of any relevant Interest Period, as the case may be, payable in
arrears on the last day of each calendar quarter of each year, commencing with
the first such date after the date hereof, and on the date such ABR Loan is
repaid, at a rate per annum (on the basis of a 365- or 366-day year for the
actual number of days involved in the case of ABR Loans which accrue interest
based upon the Prime Rate and on the basis of a 360-day year for the actual
number of days involved in the case of ABR Loans which accrue interest based
upon the Federal Funds Rate) equal to the Base Rate in effect from time to time,
which rate shall change as and when said Base Rate shall change.

               (b) Interest on Competitive Bid Loans. Each Competitive Bid Loan
shall bear interest from the date of such Competitive Bid Loan until maturity
thereof or until such Competitive Bid Loan is repaid, payable in arrears, with
respect to a term of 90 days or less, on the maturity date of such Competitive
Bid Loan, and with respect to a term of more than 90 days, on the day which is
90 days after the date of such Competitive Bid Loan and the last day of each
subsequent 90-day period thereafter or, if sooner, the maturity date of such
Competitive Bid Loan, at a rate per annum (on the basis of a 360-day year for
the actual number of days involved) equal to the Competitive Bid Rate applicable
to such Competitive Bid Loan.

        Section 4.3. Interest on Eurodollar Loans. (a) Each Eurodollar Loan
shall bear interest from the date of such Eurodollar Loan until maturity thereof
or until such Loan is repaid, payable in arrears, with respect to Interest
Periods of three months or less, on the last day of such Interest Period, and
with respect to Interest Periods longer than three months, on the day which is
three months after the commencement of such Interest Period, and on the last day
of such Interest Period, at a rate per annum (on the basis of a 360-day year for
the actual number of days involved), determined by the Agent with respect to
each Interest Period with respect to Eurodollar Loans, equal to the sum of (i)
the Applicable Margin and (ii) LIBOR.

               (b) The Interest Period for each Eurodollar Loan shall be
selected by the Company at least three Business Days prior to the beginning of
such Interest Period. If the


                                       25
<PAGE>   30

Company fails to notify the Agent of the Interest Period for a subsequent
Eurodollar Loan at least three Business Days prior to the last day of the then
current Interest Period of an outstanding Eurodollar Loan, then such outstanding
Eurodollar Loan shall become an ABR Loan at the end of such current Interest
Period.

               (c) Notwithstanding the foregoing: (i) if any Interest Period for
a Eurodollar Loan would otherwise end on a day which is not a Business Day, such
Interest Period shall be extended to the next succeeding Business Day unless the
result of such extension would be to carry such Interest Period into another
calendar month, in which event such Interest Period shall end on the immediately
preceding Business Day; (ii) any Interest Period that begins on the last
Business Day of a calendar month (or on a day for which there is no numerically
corresponding day in the calendar month at the end of such Interest Period)
shall end on the last Business Day of a calendar month; and (iii) no Interest
Period for a Eurodollar Loan may extend beyond the Termination Date.

               (d) Eurodollar Loans shall be made by each Bank from its branch
or affiliate identified as its Eurodollar Lending Office on the signature page
hereto, or such other branch or affiliate (with respect to such Bank, its
"Eurodollar Lending Office") as it may hereafter designate to the Company and
the Agent as its Eurodollar Lending Office. A Bank shall not change its
Eurodollar Lending Office designation if it, at the time of the making of such
change, increases the amounts that would have been payable by the Company to
such Bank under this Agreement in the absence of such a change.

        Section 4.4. Conversion/Continuance. (a) The Company may request, by
delivery to the Agent of a written Conversion/Continuance Request not less than
three Business Days prior to a requested Conversion/Continuance Date, that all
or portions of the outstanding Committed Loans, in the aggregate amount of
$1,000,000 or in integral multiples of $100,000 in excess thereof (or, if the
aggregate amount of outstanding Loans is less than $1,000,000, then all such
lesser amount), to bear interest from and after the Conversion/Continuance Date
as either ABR Loans or Eurodollar Loans.

               (b) Upon receipt of any such Conversion/Continuance Request from
the Company, the Agent shall forthwith give notice to each Bank of the substance
thereof. Effective on such Conversion/Continuance Date and upon payment by the
Company of the amounts, if any, required by SECTION 5.3, the Committed Loans or
portions thereof as to which the Conversion/Continuance Request was made shall
commence to accrue interest as set forth in this ARTICLE for the interest rate
selected by the Company.

               (c) In lieu of delivering the above described notice, the Company
may give the Agent telephonic notice hereunder by the required time under this
SECTION; provided that such telephonic notice shall be confirmed by delivery of
a written notice to the Agent by no later than 4:00 p.m., New York City time,
the date of such telephonic notice.

        Section 4.5. Post Default Interest. Upon the occurrence and during the
continuation of an Event of Default, all Loans and any unpaid installment of
interest thereon shall bear interest at a rate per annum (on the basis of a
360-day year for the actual number of days involved) equal to the sum of (i) 2%
and (ii) with respect to ABR Loans, the rate of interest then applicable to ABR


                                       26
<PAGE>   31

Loans, changing as and when said rate shall change; with respect to Eurodollar
Loans, the rate of interest applicable to each such Eurodollar Loan; with
respect to Competitive Bid Loans, the Competitive Bid Rate applicable to each
such Competitive Bid Loan; and, with respect to Negotiated Rate Loans, the
agreed-upon rate of interest applicable to each such Negotiated Rate Loan,
changing as and when said rate shall change if such rate shall be subject to
change. Interest payable pursuant to this SECTION shall be payable on demand.

        Section 4.6. Maximum Interest Rate. (a) Nothing in this Agreement or the
Notes shall require the Company to pay interest at a rate exceeding the maximum
rate permitted by applicable law. Neither this SECTION nor SECTION 12.1 is
intended to limit the rate of interest payable for the account of any Bank to
the maximum rate permitted by the laws of the State of New York (or any other
applicable law) if a higher rate is permitted with respect to such Bank by
supervening provisions of U.S. Federal law.

               (b) If the amount of interest payable for the account of any Bank
on any interest payment date in respect of the immediately preceding interest
computation period, computed pursuant to this ARTICLE, would exceed the maximum
amount permitted by applicable law to be charged by such Bank, the amount of
interest payable for its account on such interest payment date shall
automatically be reduced to such maximum permissible amount.

                                   ARTICLE V.

                            DISBURSEMENT AND PAYMENT

        Section 5.1. Pro Rata Treatment. Each payment of the Facility Fee and
the Utilization Fee and each reduction of the Total Commitment shall be
apportioned among the Banks in proportion to each Bank's Pro Rata Share. Except
as provided in SECTION 5.4 or 5.5, the Committed Notes or portions thereof as to
which a Conversion/Continuance Request has been made pursuant to SECTION 4.4
shall at all times bear interest on the same basis (as ABR Loans and Eurodollar
Loans), and the Interest Periods applicable thereto, if any, shall be of the
same duration.

        Section 5.2. Method of Payment. All payments by the Company hereunder
and under the Committed Notes, the Negotiated Rate Notes and the Competitive Bid
Notes or in connection with the Letters of Credit shall be made to the Agent,
for its account or for the account of the Bank or Banks entitled thereto, as the
case may be, in lawful money of the United States and in immediately available
funds at the office of the Agent on the date when due without set-off,
counterclaim or other deduction.

        Section 5.3. Compensation for Losses.

               (a) Compensation. In the event that (i) the Company makes a
prepayment under SECTION 2.14 on a day other than the last day of the Interest
Period for the amount so prepaid, in the case of Eurodollar Loans, or the
scheduled maturity date of the amount so prepaid, in the case of Negotiated Rate
Loans or Competitive Bid Loans, (ii) a Conversion/Continuance Date selected
pursuant to SECTION 4.4 falls on a day other than the last day of the Interest
Period for the amount as to which a conversion is made, (iii) the Company


                                       27
<PAGE>   32

revokes any notice given under SECTION 2.2 requesting Eurodollar Loans, (iv)
Eurodollar Loans are converted into ABR Loans pursuant to SECTION 5.5 on a day
other than the last day of the Interest Period for the Eurodollar Loans so
converted, (v) Eurodollar Loans, Negotiated Rate Loans or Competitive Bid Loans
shall be declared to be due and payable prior to the scheduled maturity thereof
pursuant to SECTION 9.1, or (vi) the Company shall fail to borrow any
Competitive Bid Loan after accepting the Competitive Bid to make such
Competitive Bid Loan or shall fail to borrow any Negotiated Rate Loan after
delivering the Negotiated Rate Confirmation for such Negotiated Rate Loan in
accordance with SECTION 2.6, the Company shall pay to the Agent for the account
of each Bank promptly after demand by such Bank (with notice to the Agent) an
amount which will compensate such Bank for any costs and losses incurred by such
Bank as a result of such prepayment, revocation of notice, conversion,
declaration or failure to borrow in respect of funds obtained for the purpose of
making or maintaining such Bank's Eurodollar Loans, Negotiated Rate Loans or
Competitive Bid Loans, as the case may be, or any part thereof. Such
compensation shall include an amount equal to the excess, if any, of (i) the
amount of interest which would have accrued on the amount so paid or prepaid,
declared due and payable, converted, or not borrowed, for the period from the
date of such payment or prepayment or declaration or conversion or failure to
borrow to the last day of the relevant Interest Period or scheduled maturity
date, as the case may be, (or, in the case of a failure to borrow, the Interest
Period that would have commenced on the date of such failure to borrow or the
maturity date that would have been scheduled for the relevant Negotiated Rate
Loan or Competitive Bid Loan, as the case may be) in each case at the applicable
rate of interest for the relevant Loan provided for herein (excluding, however,
the Applicable Margin included therein) over (ii) the amount of interest (as
reasonably determined by such Bank) 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 London interbank market, in the case of Eurodollar Loans,
or the rate of interest (as reasonably determined by such Bank) which would have
been quoted by such Bank with respect to such amount for a comparable period, in
all other cases.

               (b) Certificate, Etc. Each Bank shall promptly notify the
Company, with a copy to the Agent, upon becoming aware that the Company may be
required to make any payment pursuant to this SECTION. When requesting payment
pursuant to this SECTION, each Bank shall provide to the Company, with a copy to
the Agent, a certificate, signed by an officer of such Bank, setting forth the
amount required to be paid by the Company to such Bank and the computations made
by such Bank to determine such amount. In the absence of manifest error, such
certificate shall be conclusive and binding on the Company as to the amount so
required to be paid by the Company to such Bank.

               (c) Participants. Subject to SECTION 12.8(e), each Participant
shall be deemed a "Bank" for the purposes of this SECTION.

        Section 5.4. Withholding, Additional Costs and Capital Adequacy.

               (a) Withholding. To the extent permitted by law, all payments
under this Agreement and under the Notes (including payments of principal and
interest) shall be payable to each Bank free and clear of any and all present
and future taxes, levies, imposts, duties, deductions, withholdings, fees,
liabilities and similar charges (collectively, the "Taxes"); provided that
"Taxes" shall not include taxes imposed on or measured by the overall net income


                                       28
<PAGE>   33

of any Bank by the United States of America or any political subdivision or
taxing authority thereof or therein, or taxes on or measured by the overall net
income of any foreign office, branch or subsidiary of such Bank by any foreign
country or subdivision thereof in which such office, branch or subsidiary is
doing business. If any Taxes are required to be withheld or deducted from any
amount payable under this Agreement or any Note, then the amount payable under
this Agreement or such Note shall be increased to the amount which, after
deduction from such increased amount of all Taxes required to be withheld or
deducted therefrom, will yield to such Bank the amount stated to be payable
under this Agreement or such Note. The Company shall execute and deliver to any
Bank upon its request such further instruments as may be necessary or desirable
to give full force and effect to any such increase, including a new Note of the
Company to be issued in exchange for any Note theretofore issued. If any of the
Taxes specified in this SECTION are paid by any Bank, the Company shall, not
later than 10 days after demand of such Bank (with a copy to the Agent) make
payment to the Agent for the account of such Bank to reimburse such Bank for
such payments, together with any interest, penalties and expenses incurred in
connection therewith, plus interest thereon commencing 10 days after such demand
at a rate per annum (based on a 360-day year for the actual number of days
involved) equal to the sum of 2% and the interest rate then applicable to ABR
Loans, changing as and when such rate shall change, from the date such payment
or payments are made by such Bank to the date of reimbursement by the Company;
provided, however, that the Company shall not be required to indemnify any Bank
or Participant for penalties and expenses that result from the gross negligence
or willful misconduct of such Bank or Participant. The Company shall deliver to
the Agent certificates or other valid vouchers for all Taxes or other charges
deducted from or paid with respect to payments made by the Company hereunder.
Notwithstanding the foregoing, the Company shall be entitled, to the extent it
is required to do so by law, to deduct or withhold (and shall not be required to
make payments as otherwise required in this SECTION on account of such
deductions or withholdings) income or other similar taxes imposed by the United
States of America from interest, fees or other amounts payable hereunder for the
account of any Bank other than a Bank (i) who is a U.S. Person for U.S. Federal
income tax purposes or (ii) who has the Prescribed Forms on file with the
Company for the applicable year to the extent deduction or withholding of such
taxes is not required as a result of such filing of such Prescribed Forms;
provided that if the Company shall so deduct or withhold any such taxes, it
shall provide a statement to the Agent and such Bank, setting forth the amount
of such taxes so deducted or withheld, the applicable rate and any other
information or documentation which such Bank may reasonably request for
assisting such Bank to obtain any allowable credits or deductions for the taxes
so deducted or withheld in the jurisdiction or jurisdictions in which such Bank
is subject to tax.

               (b) Additional Costs. If, after the date hereof, any change in
any law or regulation or in the interpretation thereof by any court or
administrative or governmental authority charged with the administration thereof
or the enactment of any law or regulation shall either (i) impose, modify or
deem applicable any reserve, special deposit or similar requirement against the
Banks' Commitments or the Loans or (ii) impose on any Bank any other condition
regarding this Agreement, the Notes, its Commitment or the Loans and the result
of any event referred to in subclause (i) or (ii) of this clause (b) shall be to
increase the cost to any Bank of maintaining its Commitment or the Loans (which
increase in cost shall be calculated in accordance with each Bank's reasonable
averaging and attribution methods) by an amount which any such Bank deems to be
material, then, upon written demand by such Bank (with a copy to


                                       29
<PAGE>   34

the Agent), the Company shall pay to the Agent for the account of such Bank
within 10 days of such written demand an amount equal to such increase in cost;
provided that in respect of any Loan, no such compensation shall be payable to
the extent that, in the reasonable opinion of such Bank, the interest rate on
the Loans has been adjusted to account for such increased cost. Such amount
shall bear interest, commencing 10 days after receipt by the Company of such
demand until payment in full thereof, at a rate per annum (based on a 360-day
year, for the actual number of days involved) equal to the sum of 2% and the
interest rate then applicable to ABR Loans, changing as and when such rate shall
change.

               (c) Capital Adequacy. If any Bank shall have determined that the
adoption of any applicable law, rule, regulation or guideline regarding capital
adequacy, or any change therein, or any change in the interpretation or
administration thereof by any governmental authority, central bank or comparable
agency charged with the interpretation or administration thereof (including any
such adoption or change made prior to the date hereof but not effective until
after the date hereof), or compliance by any Bank with any request or directive
regarding capital adequacy (whether or not having the force of law) of any such
authority, central bank or comparable agency, has or would have the effect of
reducing the rate of return on capital for any such Bank or any corporation
controlling such Bank as a consequence of its obligations under this Agreement
to a level below that which such Bank or such corporation could have achieved
but for such adoption, change or compliance (taking into consideration such
Bank's or such corporation's policies with respect to capital adequacy), then
from time to time, not later than 10 days after written demand by such Bank
(with a copy to the Agent), the Company shall pay to the Agent for the account
of such Bank such additional amount or amounts as will compensate such Bank or
such corporation for such reduction, plus interest thereon commencing 10 days
after receipt by the Company of such written demand at a rate per annum (based
on a 360-day year, for the actual number of days involved) equal to the sum of
2% and the interest rate then applicable to ABR Loans, changing as and when such
rate shall change, from the date of such demand by such Bank to the date of
payment by the Company.

               (d) Lending Office Designations. Before giving any notice to the
Company pursuant to this SECTION, each Bank shall, if possible, designate a
different lending office if such designation will avoid the need for giving such
notice and will not, in the judgment of such Bank, be otherwise disadvantageous
to such Bank.

               (e) Certificate, Etc. Each Bank shall promptly notify the
Company, with a copy to the Agent, upon becoming aware that the Company may be
required to make any payment pursuant to this SECTION. When requesting payment
pursuant to this SECTION, each Bank shall provide to the Company, with a copy to
the Agent, a certificate, signed by an officer of such Bank, setting forth the
amount required to be paid by the Company to such Bank and the computations made
by such Bank to determine such amount. Determinations and allocations by such
Bank for purposes of this SECTION shall be conclusive, provided that such
determinations and allocations are made on a reasonable basis and are
mathematically accurate. Allocations shall not be deemed reasonable unless made
ratably, to the extent practical, to all of the affected Bank's or controlling
corporation's assets, commitments, activities or other relevant aspects of such
Bank's or controlling corporation's business. In the absence of manifest error,
such certificate shall be conclusive and binding on the Company as to the amount
so required to be paid by the Company to such Bank.


                                       30
<PAGE>   35

               (f) Participants. Subject to SECTION 12.8(e), each Participant
shall be deemed a "Bank" for the purposes of this SECTION.

        Section 5.5. Unavailability. If at any time any Bank shall have
determined in good faith (which determination shall be conclusive) that the
making or maintenance of all or any part of such Bank's Eurodollar Loans has
been made impracticable or unlawful because of compliance by such Bank in good
faith with any law or guideline or interpretation or administration thereof by
any official body charged with the interpretation or administration thereof or
with any request or directive of such body (whether or not having the effect of
law), because U.S. dollar deposits in the amount and requested maturity of such
Eurodollar Loans are not available to the Bank in the London Eurodollar
interbank market, or because of any other reason, then the Agent, upon
notification to it of such determination by such Bank, shall forthwith advise
the other Banks and the Company thereof. Upon such date as shall be specified in
such notice and until such time as the Agent, upon notification to it by such
Bank, shall notify the Company and the other Banks that the circumstances
specified by it in such notice no longer apply, (i) notwithstanding any other
provision of this Agreement, such Eurodollar Loans shall automatically and
without requirement of notice by the Company be converted to ABR Loans and (ii)
the obligation of only such Bank to allow borrowing, elections and renewals of
Eurodollar Loans shall be suspended, and, if the Company shall request in a
Committed Loan Request or Conversion/Continuance Request that such Bank make a
Eurodollar Loan, the loan requested to be made by such Bank shall instead be
made as an ABR Loan.

        Section 5.6. Additional Costs in Respect of Letters of Credit. (a)
Except in the case of increased costs attributable to the imposition of taxes as
to which the Company's liability is governed by SECTION 5.4(a), if as a result
of any change after the date hereof in applicable law or regulation or in the
interpretation thereof by any Governmental Authority there shall be imposed,
modified or deemed applicable any reserve, special deposit, capital adequacy
requirement or other requirements against or with respect to or measured by
reference to Letters of Credit issued or to be issued by the Issuing Bank
hereunder and the result shall be to increase the cost to the Issuing Bank (or,
as appropriate, any corporation controlling the Issuing Bank) of issuing or
maintaining any Letter of Credit hereunder, or reduce any amount receivable by
the Issuing Bank hereunder in respect of any Letter of Credit (which increase in
cost, or reduction in amount receivable shall be the result of the Issuing
Bank's (or such corporation's) reasonable allocation of the aggregate of such
increases or reductions resulting from such event), the Company shall, upon
demand by the Issuing Bank, pay to the Issuing Bank within 10 days of such
written demand such additional amounts as the Issuing Bank from time to time
specifies as necessary to compensate the Issuing Bank (or such corporation) for
such increased costs or reductions in amounts receivable plus interest thereon
commencing 10 days after such demand at a rate per annum (based on a 360-day
year for the actual number of days involved) equal to the sum of 2% and the
interest rate then applicable to ABR Loans, changing as and when such rate shall
change, from the date of such demand to the date of reimbursement by the
Company.

               (b) Certificate, Etc. The Issuing Bank shall promptly notify the
Company, with a copy to the Agent, upon becoming aware that the Company may be
required to make any payment pursuant to this SECTION. When requesting payment
pursuant to this SECTION, the Issuing Bank shall provide to the Company, with a
copy to the Agent, a certificate, signed by an officer of the Issuing Bank,
setting forth the amount required to be paid by the Company to the


                                       31
<PAGE>   36

Issuing Bank and the computations made by the Issuing Bank to determine such
amount. Determinations and allocations by the Issuing Bank for purposes of this
SECTION shall be conclusive, provided that such determinations and allocations
are made on a reasonable basis and are mathematically accurate. Allocations
shall not be deemed reasonable unless made ratably, to the extent practical, to
all the Issuing Bank's (or the relevant controlling corporation's) assets,
commitments, activities and other relevant aspects of the Issuing Bank's (or
such corporation's) business. In the absence of manifest error, such certificate
shall be conclusive and binding on the Company as to the amount so required to
be paid by the Company to the Issuing Bank. Notwithstanding anything to the
contrary contained herein, the Company shall not be required to make any payment
to the Issuing Bank pursuant to this SECTION with respect to costs, reductions
or other amounts relating to any time which is greater than 30 days prior to the
Issuing Bank's request therefor.

        Section 5.7. Commercial Practices in Respect of Letters of Credit.
Without affecting any rights the Banks may have under applicable law (including
under the Uniform Customs and Practices for Documentary Credits (1993
Revisions), International Chamber of Commerce Publication No. 500, as the same
may be amended and in effect from time to time), the Company agrees that none of
the Banks, the Issuing Bank or the Agent nor any of their respective officers or
directors shall be liable or responsible for, and the obligations of the Company
to the Banks, the Issuing Bank and the Agent hereunder shall not in any manner
be affected by: (i) the use that may be made of any Letter of Credit or the
proceeds thereof by the beneficiary thereof or any other Person; (ii) the
validity, sufficiency or genuineness of documents other than Letters of Credit,
or of any endorsement(s) thereon, even if such documents should, in fact, prove
to be in any or all respects invalid, insufficient, fraudulent or forged; or
(iii) any other circumstances whatsoever in making or failing to make payment
under any Letter of Credit; provided that the foregoing shall not operate to bar
a claim against a Bank or the Issuing Bank to the extent, but only to the
extent, of any direct, as opposed to consequential, damages suffered by the
Company that are caused by such Bank's or Issuing Bank's willful misconduct or
gross negligence in determining whether documents presented under any Letter of
Credit complied with the terms of such Letter of Credit or such Bank's or
Issuing Bank's failure to pay under such Letter of Credit after the presentation
to it of documents strictly complying with the terms and conditions of such
Letter of Credit. In furtherance and not in limitation of the foregoing, any
Bank or the Issuing Bank may accept documents that appear on their face to be in
order without responsibility for further investigation.

                                   ARTICLE VI.

                         REPRESENTATIONS AND WARRANTIES

and is duly qualified to do business and is in good standing in each
jurisdiction in which the character of the properties owned or leased by it
therein or in which the transaction of its business makes such qualification

Effect. Each of the corporate Subsidiaries are corporations, each duly organized
and validly existing under the laws of the jurisdiction of its incorporation;
each other Subsidiary is an entity duly organized and validly existing under the
laws of the jurisdiction of its organization; and each Subsidiary has the power

the transaction of its business makes such qualification necessary, except where

individually or in the aggregate, would not have a Material Adverse Effect.

               (c) Corporate Authority. The Company has full corporate power and
authority to execute, deliver and perform its obligations under each of the
Credit Documents to make the borrowings contemplated hereby, and to execute and
deliver the Notes and to incur the obligations provided for herein and therein,

transfer, reorganization, moratorium and similar laws of general applicability
relating to or affecting creditors' rights and to general equity principles.

               (f) Litigation. There are no proceedings pending or, so far as
the officers of the Company know, proceedings or investigations threatened
before any court or arbitrator or before or by any Governmental Authority which,
in any one case or in the aggregate, if determined adversely to the interests of
the Company or any of the Subsidiaries, would have a Material Adverse Effect or
relates to any Credit Document or the lending transactions contemplated hereby
and by the other Credit Documents.

               (g) No Conflicts. There is no statute, regulation, rule, order or
judgment, and no provision of any material agreement or instrument binding on
the Company or any of the Subsidiaries, or affecting their respective properties
and no provision of the certificate of incorporation, by-laws, governing

the Subsidiaries, which would prohibit, conflict with or in any way prevent the
execution, delivery, or performance of the terms of the Credit Documents or the
lending


                                       33
<PAGE>   38

transactions contemplated hereby and by the other Credit Documents, or the
incurrence of the obligations provided for in the Credit Documents, or result in
or require the creation or imposition of any Lien on any of the Company's or the
Subsidiaries' properties as a consequence of the execution, delivery and
performance of any Credit Document or the lending transactions contemplated
hereby and by the other Credit Documents.

               (h)  Financial Condition. (i) The consolidated balance sheet of

               (i) Taxes. Each of the Company and the Subsidiaries has filed or
caused to be filed all tax returns which are required to be filed and has paid
all taxes required to be shown to be due and payable on said returns or on any
assessment made against it or any of its property and all other taxes,
assessments, fees, liabilities, penalties or other charges imposed on it or any
of its property by any Governmental Authority, except for any taxes,
assessments, fees, liabilities, penalties or other charges (1) which are being
contested in good faith and for which adequate reserves (in accordance with
GAAP) have been established or (2) of which the failure to file or pay would
not, individually or in the aggregate, be material and adverse to the Company
and the Subsidiaries, taken as a whole.

               (j) Use of Proceeds. The proceeds of the Loans will be used by
the Company to consummate the Initial Transactions and for other general
corporate purposes.

               (k) Margin Regulations. No part of the proceeds of any Loan will
be used to purchase or carry, or to reduce or retire or refinance any credit
incurred to purchase or carry, or extend credit to others for the purpose of
purchasing or carrying, any "margin stock" as defined in Regulation U of the
Board of Governors of the Federal Reserve System.

               (l) No Material Misstatements. All written information relating

Property while such Property was owned or operated by the Company, (x) none of

               (t) Insurance. All of the properties (other than properties
leased to other Persons) and operations of the Company and the Subsidiaries of a

same or a similar business similarly situated are adequately insured, by
financially sound and reputable insurers, against loss or damage of the kinds
and in amounts customarily insured against by such Persons, and the Company and
the Subsidiaries carry, with such insurers in customary amounts, such other

Subsidiaries required as a result of the Year 2000 Issue to permit the proper
functioning of such computer systems and other equipment and the testing of such
systems and equipment, as so reprogrammed, other than action for which the
failure to complete would not have a Material Adverse Effect. The Company and
the Subsidiaries are undertaking reasonable efforts to assess the efforts of its
investment banks, commercial banks, primary lessees and major vendors to deal
with the Year 2000 Issue. The costs to the Company and the Subsidiaries of any
reprogramming required as a result of the Year 2000 Issue to permit the proper
functioning of the systems and equipment of the Company and the Subsidiaries and
the proper processing of data and the testing of such reprogramming are not
reasonably expected to result in an Event of Default or to have a Material
Adverse Effect on the business, properties, condition (financial or otherwise)
or operations of the Company and the Subsidiaries, taken as a whole. The "Year
2000 Issue" shall mean the failure of computer software, hardware and firmware
systems and equipment containing embedded computer chips to properly receive,
transmit, process, manipulate, store, retrieve, retransmit or in any other way
utilize data and information due to the occurrence of the year 2000 or the
inclusion of dates on or after January 1, 2000.

               (v) AHPI Acquisition Documents. As of the Effective Date, all the
representations, warranties and certifications contained in each AHPI
Acquisition Document shall be true and correct in all material respects with the
same effect as though such representations, warranties and certifications had
been made on the Effective Date.

                             THE AGENT AND THE BANKS

        Section 10.1. The Agency and Co-Documentation Agency. (a) Each Bank
appoints The Bank of New York as its Agent hereunder and irrevocably authorizes
the Agent to take such action on its behalf and to exercise such powers
hereunder as are specifically delegated to the Agent by the terms hereof,
together with such powers as are reasonably incidental hereto, and the Agent
hereby accepts such appointment subject to the terms hereof. The relationship
between the Agent and the Banks shall be that of agent and principal only and
nothing herein shall be construed to constitute the Agent a trustee for any Bank
nor to impose on the Agent duties or obligations other than those expressly
provided for herein.

               (b) Each Bank appoints each of Bank of America, N.A. and Wells
Fargo Bank, N.A. as a Co-Documentation Agent hereunder, and each
Co-Documentation Agent hereby accepts such appointment subject to the terms
hereof. Each Co-Documentation Agent, as such, shall have no duties or
obligations whatsoever under this Agreement or any Loan Document or any other
document or any matter related hereto or thereto, but shall nevertheless be
entitled to all of the indemnities and other protection afforded to the
Administrative Agent under this ARTICLE.


                                       48
<PAGE>   53

        Section 10.2. The Agent's Duties. The Agent shall promptly forward to
each Bank copies, or notify each Bank as to the contents, of all notices and
other communications received from the Company pursuant to the terms of this
Agreement and the Notes and, in the event that the Company fails to pay when due
the principal of or interest on any Loan, the Agent shall promptly give notice
thereof to the Banks. As to any other matter not expressly provided for herein
or therein, the Agent shall have no duty to act or refrain from acting with
respect to the Company, except upon the instructions of the Required Banks. The
Agent shall not be bound by any waiver, amendment, supplement, or modification
of this Agreement or any Note which affects its duties hereunder and thereunder,
unless it shall have given its prior written consent thereto. The Agent shall
have no duty to ascertain or inquire as to the performance or observance of any
of the terms, conditions, covenants or agreements binding on the Company
pursuant to this Agreement or any Note nor shall it be deemed to have knowledge
of the occurrence of any Default or Event of Default (other than a failure of
the Company to pay when due the principal or interest on any Loan), unless it
shall have received written notice from the Company or a Bank specifying such
Default or Event of Default and stating that such notice is a "Notice of
Default", and promptly after its receipt of any such written notice, the Agent
shall give the Company and each Bank a copy thereof.

        Section 10.3. Sharing of Payment and Expenses. All funds for the account
of the Banks received by the Agent in respect of payments made by the Company
pursuant to, or from any Person on account of, this Agreement or any Note shall
be distributed forthwith by the Agent among the Banks, in like currency and
funds as received, ratably in proportion to their respective interests therein.
In the event that any Bank shall receive from the Company or any other source
any payment of, on account of, or for or under this Agreement or any Note
(whether received pursuant to the exercise of any right of set-off, banker's
lien, realization upon any security held for or appropriated to such obligation
or otherwise as permitted by law) other than in proportion to its Pro Rata
Share, then such Bank shall purchase from each other Bank so much of its
interest in obligations of the Company as shall be necessary in order that each
Bank shall share such payment with each of the other Banks in proportion to each
Bank's Pro Rata Share; provided that no Bank shall purchase any interest of any
Bank that does not, to the extent that it may lawfully do so, set-off against
the balance of any deposit accounts maintained with it the obligations due to it
under this Agreement. In the event that any purchasing Bank shall be required to
return any excess payment received by it, the purchase shall be rescinded and
the purchase price restored to the extent of such return, but without interest.
In the case of any payment allocable to more than one party hereto that are made
with respect to obligations pursuant to this Agreement or any Note incurred
prior to the date hereof, such payments shall be apportioned, as applicable and
to the extent that such payment is attributable to the period prior to the date
hereof, according to each such party's Commitment or other rights hereunder as
they existed prior to such date.

        Section 10.4. The Agent's Liabilities. Each of the Banks and the Company
agrees that (i) neither the Agent in such capacity nor any of its officers or
employees shall be liable for any action taken or omitted to be taken by any of
them hereunder except for its or their own gross negligence or willful
misconduct, (ii) neither the Agent in such capacity nor any of its officers or
employees shall be liable for any action taken or omitted to be taken by any of
them in good faith in reliance upon the advice of counsel, independent public
accountants or other experts selected by the Agent, (iii) the Agent in such
capacity shall be entitled to rely upon any notice, consent, certificate,
statement or other document (including any telegram, cable, telex, facsimile or


                                       49
<PAGE>   54

telephone transmission) believed by it to be genuine and correct and to have
been signed and/or sent by the proper Persons, and (iv) the Agent in such
capacity shall be entitled to rely upon any statement made to it orally or by
telephone and believed by it to have been made by the proper Persons.

        Section 10.5. The Agent as a Bank. The Agent shall have the same rights
and powers hereunder as any other Bank and may exercise the same as though it
were not the Agent, and the terms "Bank" or "Banks", unless the context
otherwise indicated, include the Agent in its individual capacity. The Agent
may, without any liability to account, maintain deposits or credit balances for,
invest in, lend money to and generally engage in any kind of banking business
with the Company or any Subsidiary or affiliate of the Company as if it were any
other Bank and without any duty to account therefor to the other Banks.

        Section 10.6. Bank Credit Decision. Neither the Agent nor any of its
officers or employees has any responsibility for, gives any guaranty in respect
of, nor makes any representation to the Banks as to, (i) the condition,
financial or otherwise, of the Company or any Subsidiary thereof or the truth of
any representation or warranty given or made herein or in any other Credit
Document, or in connection herewith or therewith, or (ii) the validity,
execution, sufficiency, effectiveness, construction, adequacy, enforceability or
value of this Agreement or any other Credit Document or any other document or
instrument related hereto or thereto. Except as specifically provided herein and
in the other Credit Documents to which the Agent is a party, the Agent shall
have no duty or responsibility, either initially or on a continuing basis, to
provide any Bank with any credit or other information with respect to the
operations, business, property, condition or creditworthiness of the Company or
any of the Subsidiaries, whether such information comes into the Agent's
possession on or before the date hereof or at any time thereafter. Each Bank
acknowledges that it has, independently and without reliance upon the Agent or
any other Bank, based on such documents and information as it has deemed
appropriate, made its own credit analysis and decision to enter into this
Agreement. Each Bank also acknowledges that it will independently and without
reliance upon the Agent or any other Bank, 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 or any
Note.

        Section 10.7. Indemnification. Each Bank agrees (which agreement shall
survive payment of the Loans, the Reimbursement Obligations and the Notes) to
indemnify the Agent, to the extent not reimbursed by the Company, ratably in
accordance with their respective Commitments, from and against any and all
liabilities, obligations, losses, claims, damages, penalties, actions,
judgments, suits, costs, expenses or disbursements of any kind or nature
whatsoever which may be imposed on, incurred by, or asserted against the Agent
in any way relating to or arising out of this Agreement or any other Credit
Document, or any action taken or omitted to be taken by the Agent hereunder or
thereunder; provided that no Bank shall be liable for any portion of such
liabilities, obligations, losses, damages, penalties, actions, judgments, suits,
costs, expenses or disbursements resulting from the gross negligence or willful
misconduct of the Agent or any of its officers or employees. Without limiting
the foregoing, each Bank agrees to reimburse the Agent promptly upon demand for
its ratable share of any out-of-pocket expenses (including counsel fees)
incurred by the Agent in such capacity in connection with the preparation,
execution or enforcement of, or legal advice in respect of rights or
responsibilities


                                       50
<PAGE>   55

under, this Agreement or any Note or any amendments or supplements hereto or
thereto, to the extent that the Agent is not reimbursed for such expenses by the
Company.

        Section 10.8. Successor Agent. The Agent may resign at any time by
giving written notice thereof to the Banks and the Company. Upon any such
resignation, the Required Banks shall have the right to appoint a successor
Agent. If no successor Agent shall have been so appointed by the Required Banks
and shall have accepted such appointment within 30 days after the resigning
Agent's giving of notice of resignation, or the Required Banks' giving notice of
removal, as the case may be, the resigning Agent may, on behalf of the Banks,
appoint a successor Agent, which shall be a commercial bank organized under the
laws of the United States of America or of any State thereof and having a
combined capital and surplus of at least $250,000,000. Upon the acceptance of
any appointment as Agent hereunder by a successor Agent, such successor Agent
shall thereupon succeed to and become vested with all the rights, powers,
privileges and duties of the resigned or removed Agent, and the resigned or
removed Agent shall be discharged from its duties and obligations under this
Agreement. After any Agent's resignation hereunder as Agent, the provisions of
this ARTICLE shall inure to its benefit as to any actions taken or omitted to be
taken by it while it was Agent under this Agreement.

                                   ARTICLE XI.

                             CONSENT TO JURISDICTION

        Section 11.1. Consent to Jurisdiction. The Company hereby irrevocably
submits to the non-exclusive jurisdiction of the State of New York for the
purpose of any suit, action, proceeding or judgment relating to or arising out
of this Agreement and each Note. The Company hereby appoints CT Corporation
System, Inc., with offices on the date hereof at 1633 Broadway, New York, New
York 10019, as its authorized agent on whom process may be served in any action
which may be instituted against it by the Agent or the Banks in any state or
federal court in the Borough of Manhattan, The City of New York, arising out of
or relating to any Loan or this Agreement and each Note. Service of process upon
such authorized agent and written notice of such service to the Company shall be
deemed in every respect effective service of process upon the Company, and the
Company hereby irrevocably consents to the jurisdiction of any such court in any
such action and to the laying of venue in the Borough of Manhattan, The City of
New York. The Company hereby irrevocably waives any objection to the laying of
the venue of any such suit, action or proceeding brought in the aforesaid courts
and hereby irrevocably waives any claim that any such suit, action or proceeding
brought in any such court has been brought in an inconvenient forum.
Notwithstanding the foregoing, nothing herein shall in any way affect the right
of the Agent or any Bank to bring any action arising out of or relating to the
Loans or this Agreement and each Note in any competent court elsewhere having
jurisdiction over the Company or its property.

Governmental Authority by reason of the execution and delivery of this Agreement

        Section 12.4. Amendments. Any provision of this Agreement or the Notes
may be amended or waived if, but only if, such amendment or waiver is in writing
and is signed by the Company and the Required Banks (and, if the rights or
duties of the Agent or the Issuing Bank are affected thereby, by the Agent or
the Issuing Bank, respectively); provided that no such amendment, waiver or
modification shall, unless signed by all the Banks, (i) except as otherwise
provided in SECTIONS 2.4, 12.12 and 12.13, increase or decrease the Commitment

exercised from time to time. No failure on the part of the Agent or any Bank to
exercise, and no delay in exercising, any right will operate as a waiver
thereof, nor will any single or partial exercise by the Agent or any Bank of any
right preclude any other or future exercise thereof or the exercise of any other
right.

Unless otherwise provided to the contrary herein, any notice which is required

        Section 12.7. Separability. In case any one or more of the provisions
contained in this Agreement shall be invalid, illegal or unenforceable in any
respect under any law, the validity, legality and enforceability of the
remaining provisions contained herein shall not in any way be affected or
impaired thereby.

        Section 12.8. Assignments and Participations. (a) This Agreement shall
be binding upon and inure to the benefit of the Company and the Banks and their
respective successors and assigns, except that the Company may not assign any of
its rights hereunder without the prior written consent of the Banks.

               (b) Any Bank may at any time grant to one or more banks or other
institutions (each, a "Participant") participating interests in its Commitment
or any or all of its Loans. Each Bank agrees to give to the Company, with a copy
to the Agent, prior written notice of any grant of a participating interest
hereunder, which notice shall include the name of the Participant and the amount
of the interest being granted. In the event of any such grant by a Bank of a
participating interest to a Participant, whether or not upon notice to the
Company and the Agent, such Bank shall remain responsible for the performance of
its obligations hereunder, and the Company, the Issuing Bank and the Agent shall
continue to deal solely and directly with such Bank in connection with such
Bank's rights and obligations under this Agreement. Any


                                       53
<PAGE>   58

agreement pursuant to which any Bank may grant such a participating interest
shall provide that such Bank shall retain the sole right and responsibility to
enforce the obligations of the Company hereunder including the right to approve
any amendment, modification or waiver of any provision of this Agreement;
provided that such participation agreement may provide that such Bank will not
agree to any modification, amendment or waiver of this Agreement described in
clauses (i) through (v), inclusive, of SECTION 12.4 without the consent of the
Participant. Subject to SECTION 12.8(e), the Company agrees that each
Participant shall be entitled to the benefits of SECTIONS 5.3, 5.4 and 12.3(ii)
with respect to its participating interest. An assignment or other transfer
which is not permitted by clause (c) below shall be given effect for purposes of
this Agreement only to the extent of a participating interest granted in
accordance with this clause (b).

               (c) Any Bank may at any time assign to one or more banks or other
institutions (each, an "Assignee") all, or a proportionate part of all, of its
rights and obligations under this Agreement and the Notes, and such Assignee
shall assume such rights and obligations, pursuant to an instrument executed by
such Assignee and such transferor Bank, with (and subject to) the signed consent
of the Company and the Agent (which consent shall not be unreasonably withheld);
provided, however, any such assignment shall be in the minimum aggregate amount
of $10,000,000; provided, further, that the foregoing consent requirement shall
not be applicable (i) in the case of, and this subsection (c) shall not
restrict, an assignment or other transfer by any Bank to an affiliate of such
Bank or to a Federal Reserve Bank or (ii) if any event specified in SECTION
9.1(a), 9.1(g), 9.1(h), 9.1(l) or 9.1(m) has occurred and is continuing. Upon
(1) execution and delivery of such an instrument, (2) payment by such Assignee
to such transferor Bank of an amount equal to the purchase price agreed between
such transferor Bank and such Assignee and (3) payment by the transferee Bank or
transferor Bank to the Agent of an administrative fee in the amount of $3,500,
such Assignee shall be a Bank party to this Agreement and shall have all the
rights and obligations of a Bank with a Commitment as set forth in such
instrument of assumption, and the transferor Bank shall be released from its
obligations hereunder to a corresponding extent, and no further consent or
action by any party shall be required. Upon the consummation of any assignment
pursuant to this subsection (c), the transferor Bank, the Agent and the Company
shall make appropriate arrangements so that, if required, new Notes are issued
to the Assignee.

               (d) No Assignee, Participant or other transferee of any Bank's
rights shall be entitled to receive any greater payment under SECTION 5.3 or 5.4
than such Bank would have been entitled to receive with respect to the rights
transferred, unless such transfer is made with the Company's prior written
consent or by reason of the provisions of SECTION 5.4 requiring such Bank to
designate a different lending office under certain circumstances or at a time
when the circumstances giving rise to such payment did not exist.

               (e) No Participant of any Bank shall be entitled to receive any
greater payment under SECTION 5.3, 5.4 or 12.3(ii) than such Bank would have
been entitled to receive if it had not granted a participation to such
Participant.

        SECTION 12.9. WAIVER OF JURY TRIAL. THE COMPANY, THE AGENT AND EACH OF
THE BANKS HEREBY WAIVE TRIAL BY JURY IN ANY JUDICIAL PROCEEDING INVOLVING,
DIRECTLY OR INDIRECTLY, ANY MATTER


                                       54
<PAGE>   59

(WHETHER SOUNDING IN TORT, CONTRACT OR OTHERWISE) IN ANY WAY ARISING OUT OF,
RELATED TO, OR CONNECTED WITH THIS AGREEMENT, THE NOTES OR THE RELATIONSHIPS
ESTABLISHED HEREUNDER.

        Section 12.10. Confidentiality. Except as may be required to enforce the
rights and duties established hereunder, the parties hereto shall preserve in a
confidential manner all information received from the other pursuant to this
Agreement, the Notes and the transactions contemplated hereunder and thereunder,
and shall not disclose such information except to those persons with which a
confidential relationship is maintained (including regulators, affiliates, legal
counsel, accountants, or designated agents), or where required by law.

        Section 12.11. Indemnity. The Company agrees to indemnify the Agent and
each of the Banks and their respective directors, officers, employees and agents
(each such person being called an "Indemnitee") against, and to hold each
Indemnitee harmless from, any and all losses, claims, damages and liabilities of
any party other than the Company and related expenses, including reasonable
counsel fees and expenses incurred by or asserted against any Indemnitee arising
out of, in any way connected with, or as a result of (i) the execution or
delivery of this Agreement or any Note or any agreement or instrument
contemplated hereby or thereby, the performance by the parties thereto of their
respective obligations hereunder or thereunder or the consummation of the
transactions and the other transactions contemplated hereby or thereby, (ii) the
use of the proceeds of the Loans or the Letters of Credit or (iii) any claim,
litigation, investigation, or proceeding relating to any of the foregoing,
whether or not any Indemnitee is a party thereto and notwithstanding that any
claim, proceeding, investigation or litigation relating to any such losses,
claims, damages, liabilities or expenses is or was brought by a shareholder,
creditor, employee or officer of the Company; provided that such indemnity shall
not, as to any Indemnitee, be available to the extent that such losses, claims,
damages, liabilities or related expenses are determined by a court of competent
jurisdiction by final and nonappealable judgment to have resulted from the gross
negligence or willful misconduct of any Indemnitee. The provisions of this
SECTION shall remain operative and in full force and effect regardless of the
expiration of the term of this Agreement or any Letter of Credit, the
consummation of the transactions contemplated hereby, the repayment of any of
the Loans or any of the Reimbursement Obligations, the reduction or cancellation
of the Commitment, the invalidity or unenforceability of any term or provision
of any Credit Document, or any investigation made by or on behalf of the Banks.
All amounts due under this SECTION shall be payable in immediately available
funds upon written demand therefor.

        Section 12.12. Extension of Termination Dates; Removal of Banks;
Substitutions of Banks. (a) The Company may at its option, request all the Banks
then party to this Agreement to extend their scheduled Termination Dates by one
calendar year by means of a letter, in substantially the form of EXHIBIT K,
delivered to each such Bank and the Agent not earlier than 60 days prior to such
scheduled Termination Dates. Not later than 30 days after receipt of the request
to extend the Termination Dates, each such Bank electing (in its sole
discretion) so to extend its scheduled Termination Date shall execute and
deliver counterparts of such letter to the Company and the Agent, whereupon
(unless Banks with an aggregate percentage of the Total Commitment in excess of
25% decline to extend their respective scheduled Termination Dates, in which
event the Agent shall notify all the Banks thereof) such Bank's scheduled
Termination Date shall be extended by 364 calendar days so as to fall in October
of the year immediately


                                       55
<PAGE>   60

succeeding such Bank's then-current scheduled Termination Date. Any Bank failing
to respond to the extension request letter shall be deemed to have declined to
extend such Bank's scheduled Termination Date.

               (b) With respect to any Bank which has declined to extend such
Bank's scheduled Termination Date, the Company may (unless Banks with an
aggregate percentage of the Total Commitment not in excess of 25% have declined
to extend their respective scheduled Termination Dates), in its discretion, upon
not less than 30 days' prior written notice to the Agent and each Bank, remove
such Bank as a party hereto. Each such notice shall specify the date of such
removal (which shall be a Business Day), which shall thereupon become the
scheduled Termination Date for such Bank.

               (c) In the event that any Bank does not extend its scheduled
Termination Date pursuant to subsection (a) above, whether or not it is the
subject of a notice of removal pursuant to subsection (b) above, then, at any
time prior to the Termination Date for such Bank (a "Terminating Bank"), the
Company may, at its option, arrange to have one or more other financial
institutions acceptable to the Agent (which may be a Bank or Banks and each of
which shall herein be called a "Successor Bank") succeed to all or a percentage
of the Terminating Bank's outstanding Loans, if any, and rights under this
Agreement and assume all or a like percentage (as the case may be) of such
Terminating Bank's Commitment and other obligations hereunder, as if (i) in the
case of any Terminating Bank that is not the subject of a notice of removal
pursuant to subsection (a) above, such Successor Bank had extended its scheduled
Termination Date pursuant to such subsection (a) and (ii) in the case of any
Terminating Bank that is the subject of a notice of removal pursuant to
subsection (b) above, no such notice of removal had been given by the Company.
Such succession and assumption shall be effected by means of one or more
agreements supplemental to this Agreement among the Terminating Bank, the
Successor Bank, the Company and the Agent. On and as of the effective date of
each such supplemental agreement, each Successor Bank party thereto shall be and
become a Bank for all purposes of this Agreement and to the same extent as any
other Bank hereunder) and shall be bound by and entitled to the benefits of this
Agreement in the same manner as any other Bank.

               (d) On the Termination Date for any Terminating Bank, such
Terminating Bank's Commitment shall terminate and, except to the extent assigned
pursuant to subsection (c) above, the Company shall pay in full all of such
Terminating Bank's Loans and all other amounts payable to such Bank hereunder,
including any amounts payable pursuant to SECTIONS 5.3, 5.4, 12.3 and 12.11 on
account of such payment.

               (e) To the extent that all or a portion of any Terminating Bank's
obligations are not assumed pursuant to subsection (c) above, the Total
Commitment shall be reduced on the applicable Termination Date and each Bank's
percentage of the reduced Total Commitment shall be revised pro rata to reflect
such Terminating Bank's absence.

        Section 12.13. Increase of Commitments. At any time and from time to
time, the Company may, at its option, arrange for one or more Banks or one or
more other financial institutions acceptable to the Agent (an "Increasing Bank")
to increase their respective Commitments (or, in the case of such other
financial institutions, extend new Commitments hereunder) in an aggregate amount
not to exceed $26,708,000. Such increase or extension shall


                                       56
<PAGE>   61

be effected by means of one or more agreements or other documents supplemental
to this Agreement among the Increasing Banks, the Company and the Agent. In the
event that immediately after giving effect to such increase or extension
Committed Loans shall then be outstanding, then simultaneously with such
increase or extension the Banks (including the Increasing Banks) shall, subject
to the terms and conditions of this Agreement, make new Committed Loans in
accordance with their respective Commitments (immediately after giving effect to
such increase or extension) as shall be necessary to pay in full such
outstanding Committed Loans, provided that (i) the making of such new Committed
Loans and the payment in full of such outstanding Committed Loans shall be
deemed to have been made simultaneously and shall be effected in a manner
reasonably determined by the Agent through means of one or more advances and/or
payments made directly among the Banks on a netted basis through the Agent and
(ii) upon the consummation thereof, the Banks, the Agent and the Company shall
make appropriate arrangements so that, if required, new Notes are issued to the
Banks. On and as of the effective date of each such increase or extension, each
Increasing Bank shall be and become a Bank for all purposes of this Agreement
(to the same extent as any other Bank hereunder) and shall be bound by and
entitled to the benefits of this Agreement in the same manner as any other Bank.

        Section 12.14 Knowledge of the Company. As used in this Agreement,
knowledge of the Company shall mean to the best of any officer's knowledge,
after a reasonable investigation.

        Section 12.15. Execution in Counterparts. This Agreement may be executed
in any number of counterparts and by the different parties hereto on separate
counterparts, each of which when so executed and delivered shall be an original,
but all the counterparts shall together constitute one and the same instrument.

                       364-DAY REVOLVING CREDIT AGREEMENT


               364-DAY REVOLVING CREDIT AGREEMENT, dated as of November 3, 1999
(this "Agreement"), among Health Care Property Investors, Inc., a Maryland
corporation (the "Company"), each of the banks identified on the signature pages
hereof (each, a "Bank" and, collectively, the "Banks"), The Bank of New York, as
Agent for the Banks (the "Agent"), and Bank of America, N.A. and Wells Fargo
Bank, N.A., as Co-Documentation Agents, with BNY Capital Markets, Inc., as Lead
Arranger and Book Manager:

                              W I T N E S S E T H:

               WHEREAS, the Company has requested the Banks to lend up to
$103,000,000 to the Company on a revolving basis to refinance certain existing
indebtedness, to finance the acquisition of American Health Properties, Inc., a
Delaware corporation ("AHPI"), and for other general corporate purposes;

               NOW, THEREFORE, the parties hereby agree as follows:

                                   ARTICLE I.

                                   DEFINITIONS

       Section 1.1. Definitions.


               (a)  Terms Generally. The definitions ascribed to terms in this
SECTION and elsewhere in this Agreement shall apply equally to both the singular
and plural forms of the terms defined. Whenever the context may require, any
pronoun shall include the corresponding masculine, feminine and neuter forms.
The words "include", "includes" and "including" shall be deemed to be followed
by the phrase "without limitation". The words "hereby", "herein", "hereof",
"hereunder" and words of similar import refer to this Agreement as a whole
(including any exhibits and schedules hereto) and not merely to the specific
section, paragraph or clause in which such word appears. All references herein
to Articles, Sections, Exhibits and Schedules shall be deemed references to
Articles and Sections of, and Exhibits and Schedules to, this Agreement unless
the context shall otherwise require. Except as otherwise expressly provided
herein, (i) all references to "dollars" or "$" shall be deemed references to the
lawful money of the United States of America, and (ii) any definition of or
reference to any agreement, instrument or other document herein shall be
construed as referring to such agreement, instrument or other document as from
time to time amended, supplemented or otherwise modified (subject to any
restrictions on such amendments, supplements or other modifications set forth
herein).

               (b)  Accounting Terms. Except as otherwise expressly provided
herein, all terms of an accounting or financial nature shall be construed in
accordance with GAAP, as in effect from time to time; provided, however, that,
for purposes of determining compliance with any covenant set forth in SECTION
7.2(a), 7.2(b), 7.2(c), 7.2(d) or 7.3 which requires financial computations, if
any such change in GAAP would have a material effect on such computations, then
such terms shall be construed in accordance with GAAP as in effect on the date
of this


<PAGE>   6

Agreement applied on a basis consistent with the construction thereof applied in
preparing the Company's audited financial statements referred to in SECTION
5.1(h). In the event there shall occur a change in GAAP which but for the
foregoing proviso would affect the computation used to determine compliance with
any covenant set forth in SECTION 7.2(a), 7.2(b), 7.2(c) or 7.3 which requires
financial computations, the Company and the Banks agree to negotiate in good
faith in an effort to agree upon an amendment to this Agreement that will permit
compliance with such covenant to be determined by reference to GAAP as so
changed while affording the Banks the protection afforded by such covenant prior
to such change (it being understood, however, that such covenant shall remain in
full force and effect in accordance with its existing terms pending the
execution by the Company and the Banks of any such amendment).

               (c) Other Terms. The following terms shall have the meanings
ascribed to them below or in the Sections of this Agreement indicated below:

               "ABR Loans" shall mean Committed Loans which bear interest at a
rate based upon the Base Rate and in the manner set forth in SECTION 3.2.

               "Adverse Environmental Condition" shall mean any of the matters
referred to in clauses (i) or (ii) of the definition of Environmental Claim.

               "Affiliate" shall mean, with respect to any Person, any other
Person directly or indirectly controlling, controlled by, or under direct or
indirect common control with such Person. A Person shall be deemed to control
another Person if such first Person possesses, directly or indirectly, the power
to direct or cause the direction of the management and policies of such other
Person, whether through ownership of stock, by contract or otherwise.

               "Agent" shall have the meaning given to such term in the preamble
of this Agreement and shall also include any successor agent hereunder.

               "Agreement" shall have the meaning given to such term in the
preamble.

               "AHPI" shall have the meaning given to such term in the preamble.

               "AHPI Merger Documents" shall mean the Agreement and Plan of
Merger, dated as of August 4, 1999, between the Company and AHPI, and each
agreement, instrument or other document executed or delivered in connection
therewith.

               "Applicable Margin" shall mean the margin set forth in the
following chart applicable to the Pricing Level then in effect:

Subject to clauses (i), (ii) and (iii) below, "Pricing Level I" shall be
applicable for so long as the rating of the Company's unsecured (non-credit
enhanced) senior long term debt ("Senior Debt Rating") is greater than or equal
to A by Standard & Poor's Ratings Services, a division of The McGraw Hill
Companies, Inc., or any successor thereto ("S&P"), or greater than or equal to
A2 by Moody's Investors Service, Inc., or any successor thereto ("Moody's");
"Pricing Level II" shall be applicable for so long as the Senior Debt Rating is
greater than or equal to A- by S&P or greater than or equal to A3 by Moody's and
Pricing Level I is not applicable; "Pricing Level III" shall be applicable for
so long as the Senior Debt Rating is greater than or equal to BBB+ by S&P or
greater than or equal to Baa1 by Moody's and neither Pricing Level I nor II is
applicable; "Pricing Level IV" shall be applicable for so long as the Senior
Debt Rating is greater than or equal to BBB by S&P or greater than or equal to
Baa2 by Moody's and none of Pricing Level I, II or III is applicable; "Pricing
Level V" shall be applicable for so long as the Senior Debt Rating is greater
than or equal to BBB- by S&P or greater than or equal to Baa3 by Moody's and
none of Pricing Level I, II, III or IV is applicable; and "Pricing Level VI"
shall be applicable for so long as none of Pricing Level I, II, III, IV or V is
applicable.

               Notwithstanding the foregoing, (i) in the event of a split rating
as between S&P and Moody's by more than one equivalent rating level, then the
Pricing Level shall be determined by a rating that is one rating higher than the
lower of the two ratings; (ii) in the event that no Senior Debt Rating is made
available by S&P and Moody's and the Company's senior subordinated unsecured
debt rating is made available by S&P or Moody's, then for purposes of the
foregoing determinations the Senior Debt Rating shall be deemed to be one rating
higher than such subordinated unsecured debt rating (e.g., if such subordinated
unsecured debt rating by S&P is A-, then the Senior Debt Rating by S&P shall be
deemed to be A); and (iii) in the event that no Senior Debt Rating and no such
subordinated unsecured debt rating are made available by S&P and Moody's, then
Pricing Level VI above shall apply.

               "Assignee" shall have the meaning given to such term in SECTION
11.8(c).

                                    THE LOANS

       Section 2.1. Committed Loans. Prior to the Termination Date, and subject
to the terms and conditions of this Agreement, upon the request of the Company,
and upon the satisfaction by the Company or the waiver by each of the Banks of
each of the conditions contained in SECTION 6.2, each of the Banks, severally
and not jointly with the other Banks, agrees to make one or more Committed Loans
to the Company from time to time in an aggregate principal amount at any one
time outstanding not to exceed its Commitment; provided, however, that the sum
of (i) the aggregate principal amount of outstanding Committed Loans, (ii) the
aggregate principal amount of outstanding Negotiated Rate Loans and (iii) the
aggregate principal amount of outstanding Competitive Bid Loans may not exceed
the Total Commitment.

       Section 2.2. Procedure for Committed Loans. (a) The Company may borrow
Committed Loans by delivering a written Committed Loan Request to the Agent (i)
at or before 11:00 a.m., New York City time, on the requested Borrowing Date
therefor, in the case of ABR Loans, or (ii) at or before 12:00 noon, New York
City time, on the date not less than three Business Days prior to the requested
Borrowing Date therefor, in the case of Eurodollar Loans. Committed Loans shall
be in the minimum aggregate amount of $1,000,000 or in integral multiples of
$100,000 in excess thereof.

               (b) Upon receipt of any Committed Loan Request from the Company,
the Agent shall forthwith give notice to each Bank of the substance thereof. Not
later than 2:00 p.m., New York City time, on the Borrowing Date specified in
such Committed Loan Request, each Bank shall make available to the Agent in
immediately available funds at the office of the Agent at its address set forth
on the signature pages hereof, such Bank's Pro Rata Share of the requested
Committed Loans.

               (c) Upon receipt by the Agent of all such funds, the Agent shall
disburse to the Company on the requested Borrowing Date the Committed Loans
requested in such Committed Loan Request. The Agent may, but shall not be
required to, advance on behalf of any Bank such Bank's Pro Rata Share of the
Committed Loans on a Borrowing Date unless such Bank shall have notified the
Agent prior to such Borrowing Date that it does not intend to make available its
Pro Rata Share of such Committed Loans on such date. If the Agent makes such
advance, the Agent shall be entitled to recover such amount on demand from the
Bank on whose behalf such advance was made, and if such Bank does not pay the
Agent the amount of such advance on demand, the Company shall promptly repay
such amount to the Agent. Until such amount is repaid to the Agent by such Bank
or the Company, such advance shall be deemed for all purposes to be a Loan made
by the Agent. The Agent shall be entitled to recover from the Bank or the
Company, as the case may be, interest on the amount advanced by it for each day
from the Borrowing Date therefor until repaid to the Agent, at a rate per annum
equal to (i) in the case of the Bank, (1) the Federal Funds Rate, for the
five-day period beginning on the Borrowing Date, and (2) the applicable rate on
the Loans made on the Borrowing Date, for the period beginning on the sixth day
after the Borrowing Date, and (ii) in the case of the Company, the applicable
rate on the Loans made on the Borrowing Date.

               (d) In lieu of delivering the written notice described above, the
Company may give the Agent telephonic notice of any request for borrowing by the
time required under this SECTION; provided that such telephonic notice shall be
confirmed by delivery of a written Committed Loan Request to the Agent by no
later than 3:00 p.m., New York City time, on the date of such telephonic notice.

       Section 2.3. Committed Notes. The Company's obligation to repay the
Committed Loans shall be evidenced by Committed Notes, one such Committed Note
payable to the order of each Bank. The Committed Note of each Bank shall (i) be
in the principal amount of such Bank's Commitment, (ii) be dated the date of the
initial Committed Loan and (iii) be stated to mature on the Termination Date as
such date may be extended hereunder and bear interest from its date until
maturity on the principal balance (from time to time outstanding thereunder)
payable at the rates and in the manner provided herein. Each Bank is authorized
to indicate upon the grid attached to its Committed Note all Committed Loans
made by it pursuant to this Agreement, interest elections and payments of
principal and interest thereon. Such notations shall be presumptive as to the
aggregate unpaid principal amount of all Committed Loans made by such Bank, and
interest due thereon, but the failure by any Bank to make such notations or the
inaccuracy or incompleteness of any such notations shall not affect the
obligations of the Company hereunder or under the Committed Notes.

       Section 2.4. Cancellation or Reduction of the Commitment. The Company
shall have the right, upon not less than three Business Days' written notice to
the Agent and upon payment of the Facility Fees accrued through the date of such
cancellation or reduction, with respect to the amount of the cancellation or
reduction, to cancel the Total Commitment in full or to reduce the amount
thereof; provided, however, that the Total Commitment may not be canceled so
long as any Loan remains outstanding; and provided, further, that the amount of
any partial reduction in the Total Commitment shall not exceed the remainder of
(i) the Total Commitment on such date minus (ii) the aggregate outstanding
principal amount of all Committed Loans, Negotiated Rate Loans and Competitive
Bid Loans on such date. Partial reductions of the Total Commitment shall be in
the amount of $5,000,000 or in integral multiples of $1,000,000 in excess
thereof (or, if the aggregate outstanding amount of all Loans is less than
$5,000,000, then all of such lesser amount). All such cancellations or
reductions shall be permanent.

       Section 2.5. Negotiated Rate Loans. On the terms and subject to the
conditions of this Agreement, each Bank, severally and for itself alone, may
(but is not obligated to) make one or more Negotiated Rate Loans to the Company
from time to time on or after the Effective Date and prior to such Bank's
Termination Date in amounts determined as indicated in the Negotiated Rate
Confirmation and for a term that, for each Negotiated Rate Loan, is not less
than one day nor more than 270 days from the date of funding of such Negotiated
Rate Loan as provided in SECTION 2.7; provided that the aggregate principal
amount of all outstanding Loans shall not at any time exceed the then Total
Commitment.

       Section 2.6. Procedure for Negotiated Rate Loans. The Company may, from
time to time, approach one or more of the Banks to determine whether such Bank
or Banks will make one or more Negotiated Rate Loans. The Company and any Bank
or Banks shall, if each of them in their sole discretion elects to do so, agree
to enter into one or more Negotiated Rate Loans as part of such proposed
Negotiated Rate Borrowing on mutually agreed-upon terms and notify the


                                       15
<PAGE>   20

Agent by delivering a written Negotiated Rate Confirmation from the Company and
the Bank or Banks proposing to make Negotiated Rate Loans before 12:30 p.m. (New
York City time) on the date of the funding of such Negotiated Rate Loan, which
shall be a Business Day (the "Negotiated Rate Funding Date"). Such Negotiated
Rate Confirmation shall specify the amount of each Negotiated Rate Loan that
such Bank or Banks will make as part of such proposed Negotiated Rate Borrowing
(which amounts may, subject to the proviso in SECTION 2.5, exceed each such
Bank's Commitment), the Negotiated Rate Funding Date, the date or dates of
maturity thereof, which date or dates may not occur after the Termination Date,
the rate or rates of interest applicable thereto and all other terms thereof.
Each Negotiated Rate Loan shall be made pursuant to a Negotiated Rate
Confirmation. In lieu of delivering the written Negotiated Rate Confirmation
described above, the Company may give the Agent telephonic notice of any
Negotiated Rate Borrowing by the time required under this clause (a), provided
that such telephonic notice shall be confirmed by delivery of a written
Negotiated Rate Confirmation to the Agent by no later than 2:00 p.m., New York
City time, on the date of such telephonic notice.

       Section 2.7. Funding of Negotiated Rate Loans. No later than 2:00 p.m.
(New York City time) on the Negotiated Rate Funding Date, each Bank will make
available to the Agent in dollars and immediately available funds at the office
of the Agent at its address set forth on the signature pages hereof the
Negotiated Rate Loan, if any, to be made by such Bank as part of the Negotiated
Rate Borrowing to be made on such date in the manner provided above. Upon
receipt by the Agent of all such funds, the Agent shall disburse to the Company
on such date such Negotiated Rate Loan in like funds at the Company's account
specified in the relevant Negotiated Rate Confirmation. The Agent may, but shall
not be required to, advance on behalf of any Bank such Bank's Negotiated Rate
Loan on a Borrowing Date unless such Bank shall have notified the Agent prior to
such Borrowing Date that it does not intend to make available such Negotiated
Rate Loan on such date. If the Agent makes such advance, the Agent shall be
entitled to recover such amount on demand from the Bank on whose behalf such
advance was made, and if such Bank does not pay the Agent the amount of such
advance on demand, the Company shall promptly repay such amount to the Agent.
Until such amount is repaid to the Agent by such Bank or the Company, such
advance shall be deemed for all purposes to be a Negotiated Rate Loan made by
the Agent. The Agent shall be entitled to recover from the Bank or the Company,
as the case may be, interest on the amount advanced by it for each day from the
Borrowing Date therefor until repaid to the Agent, at a rate per annum equal to
(i) in the case of the Bank, (1) the Federal Funds Rate, for the five-day period
beginning on the Borrowing Date, and (2) the applicable rate on the Loans made
on the Borrowing Date, for the period beginning on the sixth day after the
Borrowing Date, and (ii) in the case of the Company, the applicable rate on the
Loans made on the Borrowing Date.

       Section 2.8. Negotiated Rate Notes. The Negotiated Rate Loans of each
Bank shall be evidenced by a Negotiated Rate Note payable to the order of each
Bank. The Negotiated Rate Note of each Bank shall (i) be in the principal amount
of $103,000,000, or such amount less than $103,000,000 as the Company and such
Bank may agree, (ii) be dated not later than the date of the initial Negotiated
Rate Confirmation relating to a Negotiated Rate Loan made by such Bank and (iii)
be stated to mature on the Termination Date as such date may be extended
hereunder and bear interest from its date until maturity on the principal
balance (from time to time outstanding thereunder) payable at the rates and in
the manner provided herein and in the applicable Negotiated Rate Confirmations.
Each Bank is authorized to indicate upon the grid


                                       16
<PAGE>   21

attached to its Negotiated Rate Note all Negotiated Rate Loans made by it
pursuant to this Agreement, interest elections and payments of principal and
interest thereon. Such notations shall be presumptive as to the aggregate unpaid
principal amount of all Negotiated Rate Loans made by such Bank, and interest
due thereon, but the failure by any Bank to make such notations or the
inaccuracy or incompleteness of any such notations shall not affect the
obligations of the Company hereunder or under the Negotiated Rate Notes.

       Section 2.9. Competitive Bid Loans. On the terms and subject to the
conditions of this Agreement, from time to time on or after the Effective Date
and prior to the Termination Date, the Company may (but is not obligated to)
make requests for Competitive Bids for Competitive Bid Loans and may (but is not
obligated to) accept Competitive Bids and borrow Competitive Bid Loans for a
term that, for each Competitive Bid Loan, is not less than seven days nor more
than 270 days from the Borrowing Date of such Competitive Bid Loan; provided
that the aggregate principal amount of all outstanding Loans shall not at any
time exceed the then Total Commitment.

       Section 2.10. Procedure for Competitive Bid Loans.

               (a) Competitive Bid Requests. To request Competitive Bids, the
Company shall deliver a written Competitive Bid Request to the Agent not later
than 1:00 p.m., New York City time, on the date not less than one Business Day
prior to the Borrowing Date of the proposed Competitive Bid Borrowing; provided
that (i) the Company may not submit more than one Competitive Bid Request on the
same day and (ii) in lieu of delivering the written Competitive Bid Request
described above, the Company may give the Agent telephonic notice of any request
for Competitive Bids by the time required under this clause (a), provided,
further, that such telephonic notice shall be confirmed by delivery of a written
Competitive Bid Request to the Agent by no later than 3:00 p.m., New York City
time, on the date of such telephonic notice. Each such Competitive Bid Request
shall specify the aggregate amount of the requested Competitive Bid Borrowing,
the proposed Borrowing Date of such Competitive Bid Borrowing, which shall be a
Business Day, the date of maturity of the Competitive Bid Loans that are
requested to be made as part of such Competitive Bid Borrowing, which date shall
be a Business Day occurring on or before the Termination Date, and the Company's
account to which funds are to be disbursed. Promptly following receipt of a
Competitive Bid Request in accordance with this SECTION, the Agent shall notify
the Banks of the details thereof by facsimile, inviting the Banks to submit
Competitive Bids.

               (b) Competitive Bids. Each Bank may in its sole and absolute
discretion make one or more Competitive Bids to the Company in response to a
Competitive Bid Request. Each Competitive Bid by a Bank must be substantially in
the form of EXHIBIT G and must be received by the Agent by facsimile not later
than 11:30 a.m., New York City time, on the proposed Borrowing Date of such
Competitive Bid Borrowing. Competitive Bids that do not conform substantially to
the form of EXHIBIT G may be rejected by the Agent, and the Agent shall notify
the applicable Bank as promptly as practicable. Each Competitive Bid shall
specify (i) the principal amount (which shall be the amount of $5,000,000 or in
integral multiples of $1,000,000 in excess thereof and which may equal the
entire principal amount of the Competitive Bid Borrowing requested by the
Company) of the Competitive Bid Loan or Loans that the Bank is willing to make,
(ii) the rate of interest (the "Competitive Bid Rate") at which the Bank is


                                       17
<PAGE>   22

prepared to make such Loan (expressed as a percentage rate per annum in the form
of a decimal to no more than four decimal places) and (iii) the term applicable
to each such Competitive Bid Loan and the date of maturity of such Competitive
Bid Loan.

               (c) Acceptance/Rejections of Competitive Bids. The Agent shall
promptly notify the Company by facsimile of the Competitive Bid Rate and the
principal amount specified in each Competitive Bid and the identity of the Bank
that shall have made such Competitive Bid. Subject only to the provisions of
this paragraph, the Company may in its sole and absolute discretion accept or
reject any Competitive Bid. The Company shall notify the Agent by telephone,
confirmed by facsimile in a form approved by the Agent, whether and to what
extent it has decided to accept or reject each Competitive Bid not later than
12:30 p.m., New York City time, on the proposed Borrowing Date of the
Competitive Bid Borrowing; provided that (i) the failure of the Company to give
such notice shall be deemed to be a rejection of each Competitive Bid, (ii) the
Company shall not accept a Competitive Bid made at a particular Competitive Bid
Rate if the Company rejects a Competitive Bid made at a lower Competitive Bid
Rate, (iii) the aggregate amount of the Competitive Bids accepted by the Company
shall not exceed the aggregate amount of the requested Competitive Bid Borrowing
specified in the related Competitive Bid Request, (iv) to the extent necessary
to comply with clause (iii) above, the Company may accept Competitive Bids at
the same Competitive Bid Rate in part, which acceptance, in the case of multiple
Competitive Bids at such Competitive Bid Rate, shall be made pro rata in
accordance with the amount of each Competitive Bid and (v) except pursuant to
clause (iv) above, no Competitive Bid shall be accepted for a Competitive Bid
Loan unless such Competitive Bid Loan is in the amount of $5,000,000 or in
integral multiples of $1,000,000 in excess thereof; provided, further, that if a
Competitive Bid Loan must be in an amount less than $5,000,000 because of the
provisions of clause (iv) above, such Competitive Bid Loan may be for an amount
of $1,000,000 or any integral multiple in excess thereof, and in calculating the
pro rata allocation of acceptances of portions of multiple Competitive Bids at a
particular Competitive Bid Rate pursuant to clause (iv) the amounts shall be
rounded to integral multiples of $1,000,000 in a manner determined by the
Company. A notice given by the Company pursuant to this paragraph shall be
irrevocable.

               (d) Competitive Bid Confirmation. The Agent shall promptly notify
each bidding Bank by facsimile whether or not its Competitive Bid has been
accepted (and, if so, the amount and Competitive Bid Rate so accepted), and each
successful bidder will thereupon become bound, on the terms and subject to the
conditions of this Agreement, to make the Competitive Bid Loan in respect of
which its Competitive Bid has been accepted.

               (e) Competitive Bids by the Agent. If the Agent shall elect to
submit a Competitive Bid in its capacity as a Bank, it shall submit such
Competitive Bid directly to the Company at least one quarter of an hour earlier
than the time by which the other Banks are required to submit their Competitive
Bids to the Agent pursuant to paragraph (b) of this SECTION.

       Section 2.11. Funding of Competitive Bid Loans. No later than 2:00 p.m.,
New York City time, on the relevant Borrowing Date, each Bank will make
available to the Agent in dollars and immediately available funds at the office
of the Agent at its address set forth on the signature pages hereof, each
Competitive Bid Loan, if any, to be made by such Bank as part of the Competitive
Bid Borrowing to be made on such date in the manner provided above. Upon


                                       18
<PAGE>   23

receipt by the Agent of all such funds, the Agent shall disburse to the Company
on such date such Competitive Bid Loan in like funds at the Company's account
specified in the relevant Competitive Bid Request. The Agent may, but shall not
be required to, advance on behalf of any Bank such Bank's Competitive Bid Loan
on a Borrowing Date unless such Bank shall have notified the Agent prior to such
Borrowing Date that it does not intend to make available such Competitive Bid
Loan on such date. If the Agent makes such advance, the Agent shall be entitled
to recover such amount on demand from the Bank on whose behalf such advance was
made, and if such Bank does not pay the Agent the amount of such advance on
demand, the Company shall promptly repay such amount to the Agent. Until such
amount is repaid to the Agent by such Bank or the Company, such advance shall be
deemed for all purposes to be a Competitive Bid Loan made by the Agent. The
Agent shall be entitled to recover from the Bank or the Company, as the case may
be, interest on the amount advanced by it for each day from the Borrowing Date
therefor until repaid to the Agent, at a rate per annum equal to (i) in the case
of the Bank, (1) the Federal Funds Rate, for the five-day period beginning on
the Borrowing Date, and (2) the applicable rate on the Loans made on the
Borrowing Date, for the period beginning on the sixth day after the Borrowing
Date, and (ii) in the case of the Company, the applicable rate on the Loans made
on the Borrowing Date.

       Section 2.12. Competitive Bid Notes. The Competitive Bid Loans of each
Bank shall be evidenced by a Competitive Bid Note payable to the order of each
Bank. The Competitive Bid Note of each Bank shall (i) be in the principal amount
of $103,000,000, (ii) be dated not later than the date of the initial
Competitive Bid Loan made by such Bank and (iii) be stated to mature on the
Termination Date as such date may be extended hereunder and bear interest from
its date until maturity on the principal balance (from time to time outstanding
thereunder) payable at the rates and in the manner provided herein. Each Bank is
authorized to indicate upon the grid attached to its Competitive Bid Note all
Competitive Bid Loans made by it pursuant to this Agreement, interest elections
and payments of principal and interest thereon. Such notations shall be
presumptive as to the aggregate unpaid principal amount of all Competitive Bid
Loans made by such Bank, and interest due thereon, but the failure by any Bank
to make such notations or the inaccuracy or incompleteness of any such notations
shall not affect the obligations of the Company hereunder or under the
Competitive Bid Notes.

       Section 2.13. Certain Fees. (a) The Company shall pay to the Agent for
the pro rata account of the Banks during the period from and including the
Effective Date through but excluding the Termination Date a fee (the "Facility
Fee") equal to the Facility Fee Rate per annum (on the basis of a 360-day year
for the actual number of days involved) on the daily average amount of the Total
Commitment during the quarter with respect to which such Facility Fee is being
paid. Such fee shall be payable in arrears on the last day of each calendar
quarter, commencing on the first such date after the Effective Date, on any date
that the Total Commitment is canceled or reduced pursuant to SECTION 2.4 (but
only with respect to the amount of such cancellation or reduction) and on the
Termination Date.

               (b) The Company shall pay to the Agent for the pro rata account
of the Banks during the period from and including the Effective Date through but
excluding the Termination Date a fee (the "Utilization Fee") equal to (i) 0.125%
per annum (on the basis of a 360-day year for the actual number of days
involved) on the daily amount during such period of the sum of (1) the aggregate
unpaid principal amount of all Committed Loans plus (2) the aggregate unpaid


                                       19
<PAGE>   24

principal amount of all committed loans and the maximum amount available to be
drawn under all issued and outstanding letters of credit (together with the
aggregate amount of all payments made by the issuing bank thereunder that have
not yet been reimbursed by or on behalf of the Company), in each case under the
Revolving Credit Agreement, dated as of November 3, 1999, among the Borrower,
the banks named therein and The Bank of New York, as agent and issuing bank,
provided that such sum is greater than 50% of the sum of the Total Commitments
on such day and the total commitments to make committed or similar loans under
such Revolving Credit Agreement on such day, multiplied by (ii) a fraction, the
numerator of which is the aggregate unpaid principal amount on such day of all
Committed Loans and the denominator of which is the sum of items (1) and (2)
above. Such fee shall be payable in arrears on the last day of each calendar
quarter, commencing on the first such date after the date hereof, and on the
Termination Date.

               (c) The Company shall pay to each of the Agent and the Banks, for
its account, fees payable in the amounts and at the times separately agreed upon
between the Company and the Agent or such Bank, as the case may be.

       Section 2.14. Optional Prepayment. The Company shall have the right, on
not less than three Business Days' written notice to the Agent, in the case of
Eurodollar Loans, and on not less than one Business Day's written notice to the
Agent, in the case of ABR Loans, Negotiated Rate Loans and Competitive Bid
Loans, to prepay Loans that, in the case of all Loans other than Negotiated Rate
Loans, bear interest on the same basis and having the same Interest Periods, if
any, or terms, as the case may be, in whole or in part, without premium or
penalty, in the aggregate principal amount of $1,000,000 or in integral
multiples of $250,000 in excess thereof (or, if the unpaid principal amount of
such Loan is less than $1,000,000, then all of such lesser amount), together
with accrued interest on the principal being prepaid to the date of prepayment,
the amounts required by SECTION 4.3 and, in the case of Negotiated Rate Loans,
such other compensation as may be agreed to by the Company and the Bank making
such Negotiated Rate Loan and as to which the Company and such Bank shall have
promptly notified the Agent; provided that the Company shall not have the right
to prepay any Negotiated Rate Loan or any Competitive Bid Loan without the prior
written consent of the Bank making such Negotiated Rate Loan or such Competitive
Bid Loan, as the case may be. Subject to the terms and conditions hereof,
prepaid Loans may be reborrowed.

                  INTEREST, METHOD OF PAYMENT, CONVERSION, ETC.

       Section 3.1. Procedure for Interest Rate Determination. (a) Unless the
Company shall request in a Committed Loan Request or in a Conversion/Continuance
Request that the Committed Loans (or portions thereof) bear interest as
Eurodollar Loans, the Committed Loans shall bear interest as ABR Loans.

               (b) Each Negotiated Rate Loan shall bear interest at the rate per
annum and subject to change or adjustment, if any, as agreed to by the Company
and the Bank making such Negotiated Rate Loan and as set forth in a Negotiated
Rate Confirmation.


                                       20
<PAGE>   25

               (c) Each Competitive Bid Loan shall bear interest at the
Competitive Bid Rate applicable to such Competitive Bid Loan.

       Section 3.2. Interest on ABR Loans and Competitive Bid Loans. (a)
Interest on ABR Loans. Each ABR Loan shall bear interest from the date of such
ABR Loan until maturity thereof or until such ABR Loan is repaid, or the
beginning of any relevant Interest Period, as the case may be, payable in
arrears on the last day of each calendar quarter of each year, commencing with
the first such date after the date hereof, and on the date such ABR Loan is
repaid, at a rate per annum (on the basis of a 365- or 366-day year for the
actual number of days involved in the case of ABR Loans which accrue interest
based upon the Prime Rate and on the basis of a 360-day year for the actual
number of days involved in the case of ABR Loans which accrue interest based
upon the Federal Funds Rate) equal to the Base Rate in effect from time to time,
which rate shall change as and when said Base Rate shall change.

               (b) Interest on Competitive Bid Loans. Each Competitive Bid Loan
shall bear interest from the date of such Competitive Bid Loan until maturity
thereof or until such Competitive Bid Loan is repaid, payable in arrears, with
respect to a term of 90 days or less, on the maturity date of such Competitive
Bid Loan, and with respect to a term of more than 90 days, on the day which is
90 days after the date of such Competitive Bid Loan and the last day of each
subsequent 90-day period thereafter or, if sooner, the maturity date of such
Competitive Bid Loan, at a rate per annum (on the basis of a 360-day year for
the actual number of days involved) equal to the Competitive Bid Rate applicable
to such Competitive Bid Loan.

       Section 3.3. Interest on Eurodollar Loans. (a) Each Eurodollar Loan shall
bear interest from the date of such Eurodollar Loan until maturity thereof or
until such Loan is repaid, payable in arrears, with respect to Interest Periods
of three months or less, on the last day of such Interest Period, and with
respect to Interest Periods longer than three months, on the day which is three
months after the commencement of such Interest Period, and on the last day of
such Interest Period, at a rate per annum (on the basis of a 360-day year for
the actual number of days involved), determined by the Agent with respect to
each Interest Period with respect to Eurodollar Loans, equal to the sum of (i)
the Applicable Margin and (ii) LIBOR.

               (b) The Interest Period for each Eurodollar Loan shall be
selected by the Company at least three Business Days prior to the beginning of
such Interest Period. If the Company fails to notify the Agent of the Interest
Period for a subsequent Eurodollar Loan at least three Business Days prior to
the last day of the then current Interest Period of an outstanding Eurodollar
Loan, then such outstanding Eurodollar Loan shall become an ABR Loan at the end
of such current Interest Period.

               (c) Notwithstanding the foregoing: (i) if any Interest Period for
a Eurodollar Loan would otherwise end on a day which is not a Business Day, such
Interest Period shall be extended to the next succeeding Business Day unless the
result of such extension would be to carry such Interest Period into another
calendar month, in which event such Interest Period shall end on the immediately
preceding Business Day; (ii) any Interest Period that begins on the last
Business Day of a calendar month (or on a day for which there is no numerically
corresponding day in the calendar month at the end of such Interest Period)
shall end on the last Business Day


                                       21
<PAGE>   26

of a calendar month; and (iii) no Interest Period for a Eurodollar Loan may
extend beyond the Termination Date.

               (d) Eurodollar Loans shall be made by each Bank from its branch
or affiliate identified as its Eurodollar Lending Office on the signature page
hereto, or such other branch or affiliate (with respect to such Bank, its
"Eurodollar Lending Office") as it may hereafter designate to the Company and
the Agent as its Eurodollar Lending Office. A Bank shall not change its
Eurodollar Lending Office designation if it, at the time of the making of such
change, increases the amounts that would have been payable by the Company to
such Bank under this Agreement in the absence of such a change.

       Section 3.4. Conversion/Continuance. (a) The Company may request, by
delivery to the Agent of a written Conversion/Continuance Request not less than
three Business Days prior to a requested Conversion/Continuance Date, that all
or portions of the outstanding Committed Loans, in the aggregate amount of
$1,000,000 or in integral multiples of $100,000 in excess thereof (or, if the
aggregate amount of outstanding Loans is less than $1,000,000, then all such
lesser amount), to bear interest from and after the Conversion/Continuance Date
as either ABR Loans or Eurodollar Loans.

               (b) Upon receipt of any such Conversion/Continuance Request from
the Company, the Agent shall forthwith give notice to each Bank of the substance
thereof. Effective on such Conversion/Continuance Date and upon payment by the
Company of the amounts, if any, required by SECTION 4.3, the Committed Loans or
portions thereof as to which the Conversion/Continuance Request was made shall
commence to accrue interest as set forth in this ARTICLE for the interest rate
selected by the Company.

               (c) In lieu of delivering the above described notice, the Company
may give the Agent telephonic notice hereunder by the required time under this
SECTION; provided that such telephonic notice shall be confirmed by delivery of
a written notice to the Agent by no later than 4:00 p.m., New York City time,
the date of such telephonic notice.

       Section 3.5. Post Default Interest. Upon the occurrence and during the
continuation of an Event of Default, all Loans and any unpaid installment of
interest thereon shall bear interest at a rate per annum (on the basis of a
360-day year for the actual number of days involved) equal to the sum of (i) 2%
and (ii) with respect to ABR Loans, the rate of interest then applicable to ABR
Loans, changing as and when said rate shall change; with respect to Eurodollar
Loans, the rate of interest applicable to each such Eurodollar Loan; with
respect to Competitive Bid Loans, the Competitive Bid Rate applicable to each
such Competitive Bid Loan; and, with respect to Negotiated Rate Loans, the
agreed-upon rate of interest applicable to each such Negotiated Rate Loan,
changing as and when said rate shall change if such rate shall be subject to
change. Interest payable pursuant to this SECTION shall be payable on demand.

       Section 3.6. Maximum Interest Rate. (a) Nothing in this Agreement or the
Notes shall require the Company to pay interest at a rate exceeding the maximum
rate permitted by applicable law. Neither this SECTION nor SECTION 11.1 is
intended to limit the rate of interest payable for the account of any Bank to
the maximum rate permitted by the laws of the State of


                                       22
<PAGE>   27

New York (or any other applicable law) if a higher rate is permitted with
respect to such Bank by supervening provisions of U.S. Federal law.

               (b) If the amount of interest payable for the account of any Bank
on any interest payment date in respect of the immediately preceding interest
computation period, computed pursuant to this ARTICLE, would exceed the maximum
amount permitted by applicable law to be charged by such Bank, the amount of
interest payable for its account on such interest payment date shall
automatically be reduced to such maximum permissible amount.

                                   ARTICLE IV.

                            DISBURSEMENT AND PAYMENT

       Section 4.1. Pro Rata Treatment. Each payment of the Facility Fee and the
Utilization Fee and each reduction of the Total Commitment shall be apportioned
among the Banks in proportion to each Bank's Pro Rata Share. Except as provided
in SECTION 4.4 or 4.5, the Committed Notes or portions thereof as to which a
Conversion/Continuance Request has been made pursuant to SECTION 3.4 shall at
all times bear interest on the same basis (as ABR Loans and Eurodollar Loans),
and the Interest Periods applicable thereto, if any, shall be of the same
duration.

       Section 4.2. Method of Payment. All payments by the Company hereunder and
under the Committed Notes, the Negotiated Rate Notes and the Competitive Bid
Notes shall be made to the Agent, for its account or for the account of the Bank
or Banks entitled thereto, as the case may be, in lawful money of the United
States and in immediately available funds at the office of the Agent on the date
when due without set-off, counterclaim or other deduction.

       Section 4.3. Compensation for Losses.

               (a) Compensation. In the event that (i) the Company makes a
prepayment under SECTION 2.14 on a day other than the last day of the Interest
Period for the amount so prepaid, in the case of Eurodollar Loans, or the
scheduled maturity date of the amount so prepaid, in the case of Negotiated Rate
Loans or Competitive Bid Loans, (ii) a Conversion/Continuance Date selected
pursuant to SECTION 3.4 falls on a day other than the last day of the Interest
Period for the amount as to which a conversion is made, (iii) the Company
revokes any notice given under SECTION 2.2 requesting Eurodollar Loans, (iv)
Eurodollar Loans are converted into ABR Loans pursuant to SECTION 4.5 on a day
other than the last day of the Interest Period for the Eurodollar Loans so
converted, (v) Eurodollar Loans, Negotiated Rate Loans or Competitive Bid Loans
shall be declared to be due and payable prior to the scheduled maturity thereof
pursuant to SECTION 8.1, or (vi) the Company shall fail to borrow any
Competitive Bid Loan after accepting the Competitive Bid to make such
Competitive Bid Loan or shall fail to borrow any Negotiated Rate Loan after
delivering the Negotiated Rate Confirmation for such Negotiated Rate Loan in
accordance with SECTION 2.6, the Company shall pay to the Agent for the account
of each Bank promptly after demand by such Bank (with notice to the Agent) an
amount which will compensate such Bank for any costs and losses incurred by such
Bank as a result of such prepayment, revocation of notice, conversion,
declaration or failure to borrow in respect of funds obtained for the purpose of
making or maintaining such Bank's


                                       23
<PAGE>   28

Eurodollar Loans, Negotiated Rate Loans or Competitive Bid Loans, as the case
may be, or any part thereof. Such compensation shall include an amount equal to
the excess, if any, of (i) the amount of interest which would have accrued on
the amount so paid or prepaid, declared due and payable, converted, or not
borrowed, for the period from the date of such payment or prepayment or
declaration or conversion or failure to borrow to the last day of the relevant
Interest Period or scheduled maturity date, as the case may be, (or, in the case
of a failure to borrow, the Interest Period that would have commenced on the
date of such failure to borrow or the maturity date that would have been
scheduled for the relevant Negotiated Rate Loan or Competitive Bid Loan, as the
case may be) in each case at the applicable rate of interest for the relevant
Loan provided for herein (excluding, however, the Applicable Margin included
therein) over (ii) the amount of interest (as reasonably determined by such
Bank) 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 London
interbank market, in the case of Eurodollar Loans, or the rate of interest (as
reasonably determined by such Bank) which would have been quoted by such Bank
with respect to such amount for a comparable period, in all other cases.

               (b) Certificate, Etc. Each Bank shall promptly notify the
Company, with a copy to the Agent, upon becoming aware that the Company may be
required to make any payment pursuant to this SECTION. When requesting payment
pursuant to this SECTION, each Bank shall provide to the Company, with a copy to
the Agent, a certificate, signed by an officer of such Bank, setting forth the
amount required to be paid by the Company to such Bank and the computations made
by such Bank to determine such amount. In the absence of manifest error, such
certificate shall be conclusive and binding on the Company as to the amount so
required to be paid by the Company to such Bank.

               (c) Participants. Subject to SECTION 11.8(e), each Participant
shall be deemed a "Bank" for the purposes of this SECTION.

       Section 4.4. Withholding, Additional Costs and Capital Adequacy

               (a) Withholding. To the extent permitted by law, all payments
under this Agreement and under the Notes (including payments of principal and
interest) shall be payable to each Bank free and clear of any and all present
and future taxes, levies, imposts, duties, deductions, withholdings, fees,
liabilities and similar charges (collectively, the "Taxes"); provided that
"Taxes" shall not include taxes imposed on or measured by the overall net income
of any Bank by the United States of America or any political subdivision or
taxing authority thereof or therein, or taxes on or measured by the overall net
income of any foreign office, branch or subsidiary of such Bank by any foreign
country or subdivision thereof in which such office, branch or subsidiary is
doing business. If any Taxes are required to be withheld or deducted from any
amount payable under this Agreement or any Note, then the amount payable under
this Agreement or such Note shall be increased to the amount which, after
deduction from such increased amount of all Taxes required to be withheld or
deducted therefrom, will yield to such Bank the amount stated to be payable
under this Agreement or such Note. The Company shall execute and deliver to any
Bank upon its request such further instruments as may be necessary or desirable
to give full force and effect to any such increase, including a new Note of the
Company to be issued in exchange for any Note theretofore issued. If any of the
Taxes specified in this SECTION are paid by any Bank, the Company shall, not
later than 10 days after


                                       24
<PAGE>   29

demand of such Bank (with a copy to the Agent), make payment to the Agent for
the account of such Bank to reimburse such Bank for such payments, together with
any interest, penalties and expenses incurred in connection therewith, plus
interest thereon commencing 10 days after such demand at a rate per annum (based
on a 360-day year for the actual number of days involved) equal to the sum of 2%
and the interest rate then applicable to ABR Loans, changing as and when such
rate shall change, from the date such payment or payments are made by such Bank
to the date of reimbursement by the Company; provided, however, that the Company
shall not be required to indemnify any Bank or Participant for penalties and
expenses that result from the gross negligence or willful misconduct of such
Bank or Participant. The Company shall deliver to the Agent certificates or
other valid vouchers for all Taxes or other charges deducted from or paid with
respect to payments made by the Company hereunder. Notwithstanding the
foregoing, the Company shall be entitled, to the extent it is required to do so
by law, to deduct or withhold (and shall not be required to make payments as
otherwise required in this SECTION on account of such deductions or
withholdings) income or other similar taxes imposed by the United States of
America from interest, fees or other amounts payable hereunder for the account
of any Bank other than a Bank (i) who is a U.S. Person for U.S. Federal income
tax purposes or (ii) who has the Prescribed Forms on file with the Company for
the applicable year to the extent deduction or withholding of such taxes is not
required as a result of such filing of such Prescribed Forms; provided that if
the Company shall so deduct or withhold any such taxes, it shall provide a
statement to the Agent and such Bank, setting forth the amount of such taxes so
deducted or withheld, the applicable rate and any other information or
documentation which such Bank may reasonably request for assisting such Bank to
obtain any allowable credits or deductions for the taxes so deducted or withheld
in the jurisdiction or jurisdictions in which such Bank is subject to tax.

               (b) Additional Costs. If, after the date hereof, any change in
any law or regulation or in the interpretation thereof by any court or
administrative or governmental authority charged with the administration thereof
or the enactment of any law or regulation shall either (i) impose, modify or
deem applicable any reserve, special deposit or similar requirement against the
Banks' Commitments or the Loans or (ii) impose on any Bank any other condition
regarding this Agreement, the Notes, its Commitment or the Loans and the result
of any event referred to in subclause (i) or (ii) of this clause (b) shall be to
increase the cost to any Bank of maintaining its Commitment or the Loans (which
increase in cost shall be calculated in accordance with each Bank's reasonable
averaging and attribution methods) by an amount which any such Bank deems to be
material, then, upon written demand by such Bank (with a copy to the Agent), the
Company shall pay to the Agent for the account of such Bank within 10 days of
such written demand an amount equal to such increase in cost; provided that in
respect of any Loan, no such compensation shall be payable to the extent that,
in the reasonable opinion of such Bank, the interest rate on the Loans has been
adjusted to account for such increased cost. Such amount shall bear interest,
commencing 10 days after receipt by the Company of such demand until payment in
full thereof, at a rate per annum (based on a 360-day year, for the actual
number of days involved) equal to the sum of 2% and the interest rate then
applicable to ABR Loans, changing as and when such rate shall change.

               (c) Capital Adequacy. If any Bank shall have determined that the
adoption of any applicable law, rule, regulation or guideline regarding capital
adequacy, or any change therein, or any change in the interpretation or
administration thereof by any governmental


                                       25
<PAGE>   30

authority, central bank or comparable agency charged with the interpretation or
administration thereof (including any such adoption or change made prior to the
date hereof but not effective until after the date hereof), or compliance by any
Bank with any request or directive regarding capital adequacy (whether or not
having the force of law) of any such authority, central bank or comparable
agency, has or would have the effect of reducing the rate of return on capital
for any such Bank or any corporation controlling such Bank as a consequence of
its obligations under this Agreement to a level below that which such Bank or
such corporation could have achieved but for such adoption, change or compliance
(taking into consideration such Bank's or such corporation's policies with
respect to capital adequacy), then from time to time, not later than 10 days
after written demand by such Bank (with a copy to the Agent), the Company shall
pay to the Agent for the account of such Bank such additional amount or amounts
as will compensate such Bank or such corporation for such reduction, plus
interest thereon commencing 10 days after receipt by the Company of such written
demand at a rate per annum (based on a 360-day year, for the actual number of
days involved) equal to the sum of 2% and the interest rate then applicable to
ABR Loans, changing as and when such rate shall change, from the date of such
demand by such Bank to the date of payment by the Company.

               (d) Lending Office Designations. Before giving any notice to the
Company pursuant to this SECTION, each Bank shall, if possible, designate a
different lending office if such designation will avoid the need for giving such
notice and will not, in the judgment of such Bank, be otherwise disadvantageous
to such Bank.

               (e) Certificate, Etc. Each Bank shall promptly notify the
Company, with a copy to the Agent, upon becoming aware that the Company may be
required to make any payment pursuant to this SECTION. When requesting payment
pursuant to this SECTION, each Bank shall provide to the Company, with a copy to
the Agent, a certificate, signed by an officer of such Bank, setting forth the
amount required to be paid by the Company to such Bank and the computations made
by such Bank to determine such amount. Determinations and allocations by such
Bank for purposes of this SECTION shall be conclusive, provided that such
determinations and allocations are made on a reasonable basis and are
mathematically accurate. Allocations shall not be deemed reasonable unless made
ratably, to the extent practical, to all of the affected Bank's or controlling
corporation's assets, commitments, activities or other relevant aspects of such
Bank's or controlling corporation's business. In the absence of manifest error,
such certificate shall be conclusive and binding on the Company as to the amount
so required to be paid by the Company to such Bank.

               (f) Participants. Subject to SECTION 11.8(e), each Participant
shall be deemed a "Bank" for the purposes of this SECTION.

       Section 4.5. Unavailability. If at any time any Bank shall have
determined in good faith (which determination shall be conclusive) that the
making or maintenance of all or any part of such Bank's Eurodollar Loans has
been made impracticable or unlawful because of compliance by such Bank in good
faith with any law or guideline or interpretation or administration thereof by
any official body charged with the interpretation or administration thereof or
with any request or directive of such body (whether or not having the effect of
law), because U.S. dollar deposits in the amount and requested maturity of such
Eurodollar Loans are not available to the Bank in the London Eurodollar
interbank market, or because of any other


                                       26
<PAGE>   31

reason, then the Agent, upon notification to it of such determination by such
Bank, shall forthwith advise the other Banks and the Company thereof. Upon such
date as shall be specified in such notice and until such time as the Agent, upon
notification to it by such Bank, shall notify the Company and the other Banks
that the circumstances specified by it in such notice no longer apply, (i)
notwithstanding any other provision of this Agreement, such Eurodollar Loans
shall automatically and without requirement of notice by the Company be
converted to ABR Loans and (ii) the obligation of only such Bank to allow
borrowing, elections and renewals of Eurodollar Loans shall be suspended, and,
if the Company shall request in a Committed Loan Request or
Conversion/Continuance Request that such Bank make a Eurodollar Loan, the loan
requested to be made by such Bank shall instead be made as an ABR Loan.

                                   ARTICLE V.

                         REPRESENTATIONS AND WARRANTIES

as now being conducted and is duly qualified to do business and is in good
standing in each jurisdiction in which the character of the properties owned or
leased by it therein or in which the transaction of its business makes such

Credit Documents, to make the borrowings contemplated hereby, and to execute and
deliver the Notes and to incur the obligations provided for herein and therein,

transfer, reorganization, moratorium and similar laws of general applicability
relating to or affecting creditors' rights and to general equity principles.

               (f)  Litigation. There are no proceedings pending or, so far as
the officers of the Company know, proceedings or investigations threatened

or judgment, and no provision of any material agreement or instrument binding on
the Company or any of the Subsidiaries, or affecting their respective properties
and no provision of the certificate of incorporation, by-laws, governing
partnership agreement or other organizational document of the Company or any of
the Subsidiaries, which would prohibit, conflict with or in any way prevent the
execution, delivery, or performance of the terms of the Credit Documents or the
lending transactions contemplated hereby and by the other Credit Documents, or
the incurrence of the obligations provided for in the Credit Documents, or
result in or require the creation or imposition of any Lien on any of the
Company's or the Subsidiaries' properties as a consequence of the execution,
delivery and performance of any Credit Document or the lending transactions
contemplated hereby and by the other Credit Documents.

               (h)  Financial Condition. (i) The consolidated balance sheet of

assessments, fees, liabilities, penalties or other charges imposed on it or any
of its property by any Governmental Authority, except for any taxes,
assessments, fees, liabilities, penalties or other charges (1) which are being
contested in good faith and for which adequate reserves (in accordance with
GAAP) have been established or (2) of which the failure to file or pay would
not, individually or in the aggregate, be material and adverse to the Company

been disposed of in the ordinary course of business or as would have been
permitted by this Agreement if then in effect since the date of such financial
statements, (ii) minor defects in title that do not interfere with the ability
of the Company or any of such Subsidiaries to conduct its business as now
conducted and (iii) such other items as would not, individually or in the
aggregate, be material and adverse to the Company and the Subsidiaries, taken as
a whole. All such assets and properties are free and clear of all Liens, except
Liens permitted pursuant to this Agreement.

               (n)  Leases. Except as could not, in any one case individually or
all cases in the aggregate, have a Material Adverse Effect, (i) there are no
renewal or extension options applicable to any lease to which the Company or any
Subsidiary is a party; (ii) to the Company's knowledge, no condition exists
which, with the giving of notice or the passage of time, or both, would permit
any lessee to cancel its obligations under any lease to which the Company or any
Subsidiary is a party; (iii) the Company has received no notice that any lessee
intends to cease operations at any leased property prior to the expiration of
the term of the applicable lease (other than temporarily due to casualty,

franchises, licenses and permits with or from Governmental Authorities and other
Persons as are required or necessary for them to own their properties and
conduct their business as now conducted, except for any authorizations,
consents, approvals, registrations, franchises, licenses and permits, of which
the failure to hold would not, individually or in the aggregate, be material and
adverse to the Company and the Subsidiaries, taken as a whole.

               (p)  Compliance with Laws and Charter Documents. Neither the
Company nor any Subsidiary thereof is in violation of (a) any law, statute,
rule, regulation or order of any Governmental Authority (including Environmental
Laws) applicable to it or its properties or assets or (b) its certificate of
incorporation, by-laws, governing partnership agreement or other organizational
document, except for any such violation as would not, individually or in the
aggregate, be material and adverse to the Company and the Subsidiaries, taken as
a whole.

engaged in a non-exempt prohibited transaction (as defined in Section 4975 of

       in the aggregate, be material and adverse to the Company and the
       Subsidiaries, taken as a whole, no Single-Employer Plan had an
       accumulated funding deficiency, whether or not waived, as of the last day
       of the most recent fiscal year of such Plan ended prior to the Effective
       Date and neither the Company nor any ERISA Affiliate is (1) required to
       give security to any Single-Employer Plan pursuant to Section 401(a)(29)

                    (iii)     Except those items that would not, individually or
       in the aggregate, be material to the Company and the Subsidiaries, taken
       as a whole, no liability under Section 4062, 4063, 4064 or 4069 of ERISA
       has been or is expected by the Company to be incurred by the Company or
       any ERISA Affiliate with respect to any Single-Employer Plan and neither
       the Company nor any ERISA Affiliate has incurred or expects to incur any
       withdrawal liability with respect to any Plan which is a multiemployer
       plan (as defined in Section 4001(a)(3) of ERISA).

                    (iv)      Except those items that would not, individually or
       in the aggregate, be material to the Company and the Subsidiaries, taken
       as a whole, under each Single-Employer Plan, as of the last day of the
       most recent plan year ended prior to the Effective Date, the actuarially
       determined present value of all benefit liabilities (as determined on the
       basis of the actuarial assumptions contained in the Plan's most recent
       actuarial valuation) did not exceed the fair market value of the asset of
       such Plan by more than $1,000,000, and there has been no material change
       in the financial condition of the Plan since the last day of the most
       recent plan year.

                    (v)       Insofar as the representations and warranties of
       the Company and its ERISA Affiliates contained in clauses (i) and (ii)
       above relate to any Plan which is a multiemployer plan, such
       representations and warranties are made to the best knowledge of the

the Subsidiaries is or, after giving effect to the transactions contemplated
hereby will be, an "investment company" or a company "controlled" by an
"investment company" within the meaning of the Investment Company Act of 1940,
as amended.

with respect to Properties formerly owned or operated by the Company or any
Subsidiary, such representation is limited to the period the Company or such
Subsidiary owned or operated such Properties), (iii) the Company has not
received any notices, demand letters or request for information from any
Federal, state, local or foreign governmental entity or any third


                                       31
<PAGE>   36

party indicating that the Company may be in violation of any Environmental Law
in connection with the ownership or operation of the Company's businesses, (iv)
there are no civil, criminal or administrative actions, suits, demands, claims,
hearings, investigations or proceedings pending or, to the Company's knowledge,
threatened against the Company or any Subsidiary with respect to the Company or
any Subsidiary or the Properties relating to any violation, or alleged
violation, of, or liability under, any Environmental Law, (v) no reports have
been filed, or, to the Company's knowledge, are required to be filed, by the
Company or any Subsidiary concerning the release of any Hazardous Substance or
the threatened or actual violation of any Environmental Law on or at the
Properties, (vi) to the Company's knowledge, no Hazardous Substance has been
disposed of, transferred, released or transported from any of the Properties
during the time such Property was owned or operated by the Company or the
Subsidiaries in violation of applicable Environmental Law as in effect at the
time of said activities, (vii) there have been no environmental investigations,
studies, audits, tests, reviews or other analyses conducted by or which are in
the possession of the Company relating to the Company or any Subsidiary or the
Properties which have not been delivered to the Banks prior to the Effective

(viii) are limited to the period the Company owned or operated such Properties),
(ix) there is no friable asbestos present in any Property presently owned or
operated by the Company or any Subsidiary, and no asbestos has been removed from
any Property while such Property was owned or operated by the Company, (x) none

               (t)  Insurance. All of the properties (other than properties
leased to other Persons) and operations of the Company and the Subsidiaries of a
character usually insured by companies of established reputation engaged in the
same or a similar business similarly situated are adequately insured, by
financially sound and reputable insurers, against loss or damage of the kinds
and in amounts customarily insured against by such Persons, and the Company and
the Subsidiaries carry, with such insurers in customary amounts, such other
insurance as is usually carried by companies of established reputation engaged
in the same or a similar business similarly situated.

               (u)  Year 2000. The Company and each of the Subsidiaries have
taken all necessary action to complete in all material respects the
reprogramming of computer software, hardware and firmware systems and equipment
containing embedded microchips owned or operated by or for the Company and the
Subsidiaries required as a result of the Year 2000 Issue to permit the proper
functioning of such computer systems and other equipment and the testing of such
systems and equipment, as so reprogrammed, other than action for which the
failure to complete would not have a Material Adverse Effect. The Company and
the Subsidiaries are undertaking reasonable efforts to assess the efforts of its
investment banks, commercial banks, primary lessees and major vendors to deal
with the Year 2000 Issue. The costs to the Company


                                       32
<PAGE>   37

and the Subsidiaries of any reprogramming required as a result of the Year 2000
Issue to permit the proper functioning of the systems and equipment of the
Company and the Subsidiaries and the proper processing of data and the testing
of such reprogramming are not reasonably expected to result in an Event of
Default or to have a Material Adverse Effect on the business, properties,
condition (financial or otherwise) or operations of the Company and the
Subsidiaries, taken as a whole. The "Year 2000 Issue" shall mean the failure of
computer software, hardware and firmware systems and equipment containing
embedded computer chips to properly receive, transmit, process, manipulate,
store, retrieve, retransmit or in any other way utilize data and information due
to the occurrence of the year 2000 or the inclusion of dates on or after January
1, 2000.

as though such representations, warranties and certifications had been made on
the Effective Date.

statement signed by a senior officer of the Company describing such event in
reasonable detail and the action, if any, proposed to be taken with respect
thereto. The events referred to in the preceding sentence are, with respect to

require security to be given to the Plan pursuant to Section 401(a)(29) of the
Code or Section 307 of ERISA; and (vii) failure by the Company or any ERISA
Affiliate to make payment to a Single-Employer Plan which would give rise to a

ERISA.

               (i) Environmental Matters. (i) Comply, and cause the Subsidiaries

                             THE AGENT AND THE BANKS

       Section 9.1. The Agency and Co-Documentation Agency. (a) Each Bank
appoints The Bank of New York as its Agent hereunder and irrevocably authorizes
the Agent to take such action on its behalf and to exercise such powers
hereunder as are specifically delegated to the Agent by the terms hereof,
together with such powers as are reasonably incidental hereto, and the Agent
hereby accepts such appointment subject to the terms hereof. The relationship
between the Agent and the Banks shall be that of agent and principal only and
nothing herein shall be construed to constitute the Agent a trustee for any Bank
nor to impose on the Agent duties or obligations other than those expressly
provided for herein.


                                       42
<PAGE>   47

               (b)  Each Bank appoints each of Bank of America, N.A. and Wells
Fargo Bank, N.A. as a Co-Documentation Agent hereunder, and each
Co-Documentation Agent hereby accepts such appointment subject to the terms
hereof. Each Co-Documentation Agent, as such, shall have no duties or
obligations whatsoever under this Agreement or any Loan Document or any other
document or any matter related hereto or thereto, but shall nevertheless be
entitled to all of the indemnities and other protection afforded to the
Administrative Agent under this Article.

       Section 9.2. The Agent's Duties. The Agent shall promptly forward to each
Bank copies, or notify each Bank as to the contents, of all notices and other
communications received from the Company pursuant to the terms of this Agreement
and the Notes and, in the event that the Company fails to pay when due the
principal of or interest on any Loan, the Agent shall promptly give notice
thereof to the Banks. As to any other matter not expressly provided for herein
or therein, the Agent shall have no duty to act or refrain from acting with
respect to the Company, except upon the instructions of the Required Banks. The
Agent shall not be bound by any waiver, amendment, supplement, or modification
of this Agreement or any Note which affects its duties hereunder and thereunder,
unless it shall have given its prior written consent thereto. The Agent shall
have no duty to ascertain or inquire as to the performance or observance of any
of the terms, conditions, covenants or agreements binding on the Company
pursuant to this Agreement or any Note nor shall it be deemed to have knowledge
of the occurrence of any Default or Event of Default (other than a failure of
the Company to pay when due the principal or interest on any Loan), unless it
shall have received written notice from the Company or a Bank specifying such
Default or Event of Default and stating that such notice is a "Notice of
Default", and promptly after its receipt of any such written notice, the Agent
shall give the Company and each Bank a copy thereof.

       Section 9.3. Sharing of Payment and Expenses. All funds for the account
of the Banks received by the Agent in respect of payments made by the Company
pursuant to, or from any Person on account of, this Agreement or any Note shall
be distributed forthwith by the Agent among the Banks, in like currency and
funds as received, ratably in proportion to their respective interests therein.
In the event that any Bank shall receive from the Company or any other source
any payment of, on account of, or for or under this Agreement or any Note
(whether received pursuant to the exercise of any right of set-off, banker's
lien, realization upon any security held for or appropriated to such obligation
or otherwise as permitted by law) other than in proportion to its Pro Rata
Share, then such Bank shall purchase from each other Bank so much of its
interest in obligations of the Company as shall be necessary in order that each
Bank shall share such payment with each of the other Banks in proportion to each
Bank's Pro Rata Share; provided that no Bank shall purchase any interest of any
Bank that does not, to the extent that it may lawfully do so, set-off against
the balance of any deposit accounts maintained with it the obligations due to it
under this Agreement. In the event that any purchasing Bank shall be required to
return any excess payment received by it, the purchase shall be rescinded and
the purchase price restored to the extent of such return, but without interest.
In the case of any payment allocable to more than one party hereto that are made
with respect to obligations pursuant to this Agreement or any Note incurred
prior to the date hereof, such payments shall be apportioned, as applicable and
to the extent that such payment is attributable to the period prior to the date
hereof, according to each such party's Commitment or other rights hereunder as
they existed prior to such date.

<PAGE>   48

       Section 9.4. The Agent's Liabilities. Each of the Banks and the Company
agrees that (i) neither the Agent in such capacity nor any of its officers or
employees shall be liable for any action taken or omitted to be taken by any of
them hereunder except for its or their own gross negligence or willful
misconduct, (ii) neither the Agent in such capacity nor any of its officers or
employees shall be liable for any action taken or omitted to be taken by any of
them in good faith in reliance upon the advice of counsel, independent public
accountants or other experts selected by the Agent, (iii) the Agent in such
capacity shall be entitled to rely upon any notice, consent, certificate,
statement or other document (including any telegram, cable, telex, facsimile or
telephone transmission) believed by it to be genuine and correct and to have
been signed and/or sent by the proper Persons, and (iv) the Agent in such
capacity shall be entitled to rely upon any statement made to it orally or by
telephone and believed by it to have been made by the proper Persons.

       Section 9.5. The Agent as a Bank. The Agent shall have the same rights
and powers hereunder as any other Bank and may exercise the same as though it
were not the Agent, and the terms "Bank" or "Banks", unless the context
otherwise indicated, include the Agent in its individual capacity. The Agent
may, without any liability to account, maintain deposits or credit balances for,
invest in, lend money to and generally engage in any kind of banking business
with the Company or any Subsidiary or affiliate of the Company as if it were any
other Bank and without any duty to account therefor to the other Banks.

       Section 9.6. Bank Credit Decision. Neither the Agent nor any of its
officers or employees has any responsibility for, gives any guaranty in respect
of, nor makes any representation to the Banks as to, (i) the condition,
financial or otherwise, of the Company or any Subsidiary thereof or the truth of
any representation or warranty given or made herein or in any other Credit
Document, or in connection herewith or therewith, or (ii) the validity,
execution, sufficiency, effectiveness, construction, adequacy, enforceability or
value of this Agreement or any other Credit Document or any other document or
instrument related hereto or thereto. Except as specifically provided herein and
in the other Credit Documents to which the Agent is a party, the Agent shall
have no duty or responsibility, either initially or on a continuing basis, to
provide any Bank with any credit or other information with respect to the
operations, business, property, condition or creditworthiness of the Company or
any of the Subsidiaries, whether such information comes into the Agent's
possession on or before the date hereof or at any time thereafter. Each Bank
acknowledges that it has, independently and without reliance upon the Agent or
any other Bank, based on such documents and information as it has deemed
appropriate, made its own credit analysis and decision to enter into this
Agreement. Each Bank also acknowledges that it will independently and without
reliance upon the Agent or any other Bank, 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 or any
Note.

       Section 9.7. Indemnification. Each Bank agrees (which agreement shall
survive payment of the Loans and the Notes) to indemnify the Agent, to the
extent not reimbursed by the Company, ratably in accordance with their
respective Commitments, from and against any and all liabilities, obligations,
losses, claims, damages, penalties, actions, judgments, suits, costs, expenses
or disbursements of any kind or nature whatsoever which may be imposed on,
incurred by, or asserted against the Agent in any way relating to or arising out
of this Agreement or any


                                       44
<PAGE>   49

other Credit Document, or any action taken or omitted to be taken by the Agent
hereunder or thereunder; provided that no Bank shall be liable for any portion
of such liabilities, obligations, losses, damages, penalties, actions,
judgments, suits, costs, expenses or disbursements resulting from the gross
negligence or willful misconduct of the Agent or any of its officers or
employees. Without limiting the foregoing, each Bank agrees to reimburse the
Agent promptly upon demand for its ratable share of any out-of-pocket expenses
(including counsel fees) incurred by the Agent in such capacity in connection
with the preparation, execution or enforcement of, or legal advice in respect of
rights or responsibilities under, this Agreement or any Note or any amendments
or supplements hereto or thereto, to the extent that the Agent is not reimbursed
for such expenses by the Company.

       Section 9.8. Successor Agent. The Agent may resign at any time by giving
written notice thereof to the Banks and the Company. Upon any such resignation,
the Required Banks shall have the right to appoint a successor Agent. If no
successor Agent shall have been so appointed by the Required Banks and shall
have accepted such appointment within 30 days after the resigning Agent's giving
of notice of resignation, or the Required Banks' giving notice of removal, as
the case may be, the resigning Agent may, on behalf of the Banks, appoint a
successor Agent, which shall be a commercial bank organized under the laws of
the United States of America or of any State thereof and having a combined
capital and surplus of at least $250,000,000. Upon the acceptance of any
appointment as Agent hereunder by a successor Agent, such successor Agent shall
thereupon succeed to and become vested with all the rights, powers, privileges
and duties of the resigned or removed Agent, and the resigned or removed Agent
shall be discharged from its duties and obligations under this Agreement. After
any Agent's resignation hereunder as Agent, the provisions of this ARTICLE shall
inure to its benefit as to any actions taken or omitted to be taken by it while
it was Agent under this Agreement.

                                   ARTICLE X.

                             CONSENT TO JURISDICTION

       Section 10.1. Consent to Jurisdiction. The Company hereby irrevocably
submits to the non-exclusive jurisdiction of the State of New York for the
purpose of any suit, action, proceeding or judgment relating to or arising out
of this Agreement and each Note. The Company hereby appoints CT Corporation
System, Inc., with offices on the date hereof at 1633 Broadway, New York, New
York 10019, as its authorized agent on whom process may be served in any action
which may be instituted against it by the Agent or the Banks in any state or
federal court in the Borough of Manhattan, The City of New York, arising out of
or relating to any Loan or this Agreement and each Note. Service of process upon
such authorized agent and written notice of such service to the Company shall be
deemed in every respect effective service of process upon the Company, and the
Company hereby irrevocably consents to the jurisdiction of any such court in any
such action and to the laying of venue in the Borough of Manhattan, The City of
New York. The Company hereby irrevocably waives any objection to the laying of
the venue of any such suit, action or proceeding brought in the aforesaid courts
and hereby irrevocably waives any claim that any such suit, action or proceeding
brought in any such court has been brought in an inconvenient forum.
Notwithstanding the foregoing, nothing herein shall in any way affect the right
of the Agent or any Bank to bring any action arising out of or relating


                                       45
<PAGE>   50

to the Loans or this Agreement and each Note in any competent court elsewhere
having jurisdiction over the Company or its property.

                                   ARTICLE XI.

                                  MISCELLANEOUS

granted to the Agent and the Banks hereunder or under any other document
delivered hereunder or in connection herewith, or allowed them by law or equity,
shall be cumulative and may be exercised from time to time. No failure on the
part of the Agent or any Bank to exercise, and no delay in exercising, any right
will operate as a waiver thereof, nor will any single or partial exercise by the

                          Attention: Glen B. Collyer.

Unless otherwise provided to the contrary herein, any notice which is required
to be given in writing pursuant to the terms of this Agreement may be given by
telex, telecopy or facsimile transmission.

       Section 11.7. Separability. In case any one or more of the provisions
contained in this Agreement shall be invalid, illegal or unenforceable in any
respect under any law, the validity, legality and enforceability of the
remaining provisions contained herein shall not in any way be affected or
impaired thereby.

       Section 11.8. Assignments and Participations. (a) This Agreement shall be
binding upon and inure to the benefit of the Company and the Banks and their
respective successors and assigns, except that the Company may not assign any of
its rights hereunder without the prior written consent of the Banks.

               (b) Any Bank may at any time grant to one or more banks or other
institutions (each, a "Participant") participating interests in its Commitment
or any or all of its Loans. Each Bank agrees to give to the Company, with a copy
to the Agent, prior written notice of any grant of a participating interest
hereunder, which notice shall include the name of the Participant and the amount
of the interest being granted. In the event of any such grant by a Bank of a
participating interest to a Participant, whether or not upon notice to the
Company and the Agent,


                                       47
<PAGE>   52

such Bank shall remain responsible for the performance of its obligations
hereunder, and the Company and the Agent shall continue to deal solely and
directly with such Bank in connection with such Bank's rights and obligations
under this Agreement. Any agreement pursuant to which any Bank may grant such a
participating interest shall provide that such Bank shall retain the sole right
and responsibility to enforce the obligations of the Company hereunder including
the right to approve any amendment, modification or waiver of any provision of
this Agreement; provided that such participation agreement may provide that such
Bank will not agree to any modification, amendment or waiver of this Agreement
described in clauses (i) through (v), inclusive, of SECTION 11.4 without the
consent of the Participant. Subject to SECTION 11.8(e), the Company agrees that
each Participant shall be entitled to the benefits of SECTIONS 4.3, 4.4 and
11.3(ii) with respect to its participating interest. An assignment or other
transfer which is not permitted by clause (c) below shall be given effect for
purposes of this Agreement only to the extent of a participating interest
granted in accordance with this clause (b).

               (c) Any Bank may at any time assign to one or more banks or other
institutions (each, an "Assignee") all, or a proportionate part of all, of its
rights and obligations under this Agreement and the Notes, and such Assignee
shall assume such rights and obligations, pursuant to an instrument executed by
such Assignee and such transferor Bank, with (and subject to) the signed consent
of the Company and the Agent (which consent shall not be unreasonably withheld);
provided, however, any such assignment shall be in the minimum aggregate amount
of $10,000,000; provided, further, that the foregoing consent requirement shall
not be applicable (i) in the case of, and this subsection (c) shall not
restrict, an assignment or other transfer by any Bank to an affiliate of such
Bank or to a Federal Reserve Bank or (ii) if any event specified in SECTION
8.1(a), 8.1(g), 8.1(h), 8.1(l) or 8.1(m) has occurred and is continuing. Upon
(1) execution and delivery of such an instrument, (2) payment by such Assignee
to such transferor Bank of an amount equal to the purchase price agreed between
such transferor Bank and such Assignee and (3) payment by the transferee Bank or
transferor Bank to the Agent of an administrative fee in the amount of $3,500,
such Assignee shall be a Bank party to this Agreement and shall have all the
rights and obligations of a Bank with a Commitment as set forth in such
instrument of assumption, and the transferor Bank shall be released from its
obligations hereunder to a corresponding extent, and no further consent or
action by any party shall be required. Upon the consummation of any assignment
pursuant to this subsection (c), the transferor Bank, the Agent and the Company
shall make appropriate arrangements so that, if required, new Notes are issued
to the Assignee.

               (d) No Assignee, Participant or other transferee of any Bank's
rights shall be entitled to receive any greater payment under SECTION 4.3 or 4.4
than such Bank would have been entitled to receive with respect to the rights
transferred, unless such transfer is made with the Company's prior written
consent or by reason of the provisions of SECTION 4.4 requiring such Bank to
designate a different lending office under certain circumstances or at a time
when the circumstances giving rise to such payment did not exist.

               (e) No Participant of any Bank shall be entitled to receive any
greater payment under SECTION 4.3, 4.4 or 11.3(ii) than such Bank would have
been entitled to receive if it had not granted a participation to such
Participant.

       SECTION 11.9. WAIVER OF JURY TRIAL. THE COMPANY, THE AGENT AND EACH OF
THE BANKS HEREBY WAIVE TRIAL BY JURY IN ANY JUDICIAL PROCEEDING INVOLVING,
DIRECTLY OR INDIRECTLY, ANY MATTER (WHETHER SOUNDING IN TORT, CONTRACT OR
OTHERWISE) IN ANY WAY ARISING OUT OF, RELATED TO, OR CONNECTED WITH THIS
AGREEMENT, THE NOTES OR THE RELATIONSHIPS ESTABLISHED HEREUNDER.

       Section 11.10. Confidentiality. Except as may be required to enforce the
rights and duties established hereunder, the parties hereto shall preserve in a
confidential manner all information received from the other pursuant to this
Agreement, the Notes and the transactions contemplated hereunder and thereunder,
and shall not disclose such information except to those persons with which a
confidential relationship is maintained (including regulators, affiliates, legal
counsel, accountants, or designated agents), or where required by law.

       Section 11.11. Indemnity. The Company agrees to indemnify the Agent and
each of the Banks and their respective directors, officers, employees and agents
(each such person being called an "Indemnitee") against, and to hold each
Indemnitee harmless from, any and all losses, claims, damages and liabilities of
any party other than the Company and related expenses, including reasonable
counsel fees and expenses incurred by or asserted against any Indemnitee arising
out of, in any way connected with, or as a result of (i) the execution or
delivery of this Agreement or any Note or any agreement or instrument
contemplated hereby or thereby, the performance by the parties thereto of their
respective obligations hereunder or thereunder or the consummation of the
transactions and the other transactions contemplated hereby or thereby, (ii) the
use of the proceeds of the Loans or (iii) any claim, litigation, investigation,
or proceeding relating to any of the foregoing, whether or not any Indemnitee is
a party thereto and notwithstanding that any claim, proceeding, investigation or
litigation relating to any such losses, claims, damages, liabilities or expenses
is or was brought by a shareholder, creditor, employee or officer of the
Company; provided that such indemnity shall not, as to any Indemnitee, be
available to the extent that such losses, claims, damages, liabilities or
related expenses are determined by a court of competent jurisdiction by final
and nonappealable judgment to have resulted from the gross negligence or willful
misconduct of any Indemnitee. The provisions of this SECTION shall remain
operative and in full force and effect regardless of the expiration of the term
of this Agreement, the consummation of the transactions contemplated hereby, the
repayment of any of the Loans, the reduction or cancellation of the Commitment,
the invalidity or unenforceability of any term or provision of this Agreement or
any Note, or any investigation made by or on behalf of the Banks. All amounts
due under this SECTION shall be payable in immediately available funds upon
written demand therefor.

       Section 11.12. Extension of Termination Dates; Removal of Banks;
Substitutions of Banks. (a) The Company may at its option, request all the Banks
then party to this Agreement to extend their scheduled Termination Dates by 364
calendar days by means of a letter, in substantially the form of EXHIBIT K,
delivered to each such Bank and the Agent not earlier than 60 days prior to such
scheduled Termination Dates. Not later than 30 days after receipt of the request
to extend the Termination Dates, each such Bank electing (in its sole
discretion) so to extend its scheduled Termination Date shall execute and
deliver counterparts of such letter to the Company and the Agent, whereupon
(unless Banks with an aggregate percentage of the Total Commitment in excess of
25% decline to extend their respective scheduled Termination Dates, in


                                       49
<PAGE>   54

which event the Agent shall notify all the Banks thereof) such Bank's scheduled
Termination Date shall be extended by 364 calendar days so as to fall in October
of the year immediately succeeding such Bank's then-current scheduled
Termination Date. Any Bank failing to respond to the extension request letter
shall be deemed to have declined to extend such Bank's scheduled Termination
Date.

               (b) With respect to any Bank which has declined to extend such
Bank's scheduled Termination Date, the Company may (unless Banks with an
aggregate percentage of the Total Commitment in excess of 25% have declined to
extend their respective scheduled Termination Dates), in its discretion, upon
not less than 30 days' prior written notice to the Agent and each Bank, remove
such Bank as a party hereto. Each such notice shall specify the date of such
removal (which shall be a Business Day), which shall thereupon become the
scheduled Termination Date for such Bank.

               (c) In the event that any Bank does not extend its scheduled
Termination Date pursuant to subsection (a) above, whether or not it is the
subject of a notice of removal pursuant to subsection (b) above, then, at any
time prior to the Termination Date for such Bank (a "Terminating Bank"), the
Company may, at its option, arrange to have one or more other financial
institutions acceptable to the Agent (which may be a Bank or Banks and each of
which shall herein be called a "Successor Bank") succeed to all or a percentage
of the Terminating Bank's outstanding Loans, if any, and rights under this
Agreement and assume all or a like percentage (as the case may be) of such
Terminating Bank's Commitment and other obligations hereunder, as if (i) in the
case of any Terminating Bank that is not the subject of a notice of removal
pursuant to subsection (b) above, such Successor Bank had extended its scheduled
Termination Date pursuant to such subsection (a) and (ii) in the case of any
Terminating Bank that is the subject of a notice of removal pursuant to
subsection (b) above, no such notice of removal had been given by the Company.
Such succession and assumption shall be effected by means of one or more
agreements supplemental to this Agreement among the Terminating Bank, the
Successor Bank, the Company and the Agent. On and as of the effective date of
each such supplemental agreement, each Successor Bank party thereto shall be and
become a Bank for all purposes of this Agreement (to the same extent as any
other Bank hereunder) and shall be bound by and entitled to the benefits of this
Agreement in the same manner as any other Bank.

               (d) On the Termination Date for any Terminating Bank, such
Terminating Bank's Commitment shall terminate and, except to the extent assigned
pursuant to subsection (c) above, the Company shall pay in full all of such
Terminating Bank's Loans and all other amounts payable to such Bank hereunder,
including any amounts payable pursuant to SECTIONS 4.3, 4.4, 11.3 and 11.11 on
account of such payment.

               (e) To the extent that all or a portion of any Terminating Bank's
obligations are not assumed pursuant to subsection (c) above, the Total
Commitment shall be reduced on the applicable Termination Date and each Bank's
percentage of the reduced Total Commitment shall be revised pro rata to reflect
such Terminating Bank's absence.

       Section 11.13. Increase of Commitments. At any time and from time to
time, the Company may, at its option, arrange for one or more Banks or one or
more other financial institutions acceptable to the Agent (an "Increasing Bank")
to increase their respective


                                       50
<PAGE>   55

Commitments (or, in the case of such other financial institutions, extend new
Commitments hereunder) in an aggregate amount not to exceed $13,292,000. Such
increase or extension shall be effected by means of one or more agreements or
other documents supplemental to this Agreement among the Increasing Banks, the
Company and the Agent. In the event that immediately after giving effect to such
increase or extension Committed Loans shall then be outstanding, then
simultaneously with such increase or extension the Banks (including the
Increasing Banks) shall, subject to the terms and conditions of this Agreement,
make new Committed Loans in accordance with their respective Commitments
(immediately after giving effect to such increase or extension) as shall be
necessary to pay in full such outstanding Committed Loans, provided that (i) the
making of such new Committed Loans and the payment in full of such outstanding
Committed Loans shall be deemed to have been made simultaneously and shall be
effected in a manner reasonably determined by the Agent through means of one or
more advances and/or payments made directly among the Banks on a netted basis
through the Agent and (ii) upon the consummation thereof, the Banks, the Agent
and the Company shall make appropriate arrangements so that, if required, new
Notes are issued to the Banks. On and as of the effective date of each such
increase or extension, each Increasing Bank shall be and become a Bank for all
purposes of this Agreement (to the same extent as any other Bank hereunder) and
shall be bound by and entitled to the benefits of this Agreement in the same
manner as any other Bank.

       Section 11.14. Knowledge of the Company. As used in this Agreement,
knowledge of the Company shall mean to the best of any officer's knowledge,
after a reasonable investigation.

       Section 11.15. Execution in Counterparts. This Agreement may be executed
in any number of counterparts and by the different parties hereto on separate
counterparts, each of which when so executed and delivered shall be an original,
but all the counterparts shall together constitute one and the same instrument.
