              NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

     1.   The information presented for the interim periods is unaudited, but
includes all adjustments (consisting only of normal recurring adjustments)
which, in the opinion of HPSC, Inc. (the "Company"), are necessary for a fair
presentation of the financial position, results of operations and cash flows for
the periods presented. The results for interim periods are not necessarily
indicative of results to be expected for the full fiscal year. Certain 1999
account balances have been reclassified to conform with 2000 presentation. Such
financial statements have been prepared in accordance with the instructions of
Form 10-Q pursuant to the rules and regulations of the Securities and Exchange
Commission. Certain information and footnote disclosures have been omitted
pursuant to such rules and regulations. As a result, these financial statements
should be read in conjunction with the audited consolidated financial statements
and related notes included in the Company's latest annual report on Form 10-K.

     2.   The Company computes and presents its earnings per share data in
accordance with Statement of Financial Accounting Standards ("SFAS") No. 128,
"Earnings per Share". The Company's basic net income per share calculation is
based on the weighted average number of common shares outstanding, which does
not include unallocated shares under the Company's Employee Stock Ownership Plan
("ESOP"), restricted shares issued under the Company's Incentive Stock Plans,
treasury stock, or any shares issuable upon the exercise of outstanding stock
options. Diluted net income per share includes the weighted average number of
stock options and contingently issuable restricted shares under the Company's
Incentive Stock Plans outstanding as calculated under the treasury stock method,
but not treasury stock or unallocated shares under the Company's ESOP.

     3.   In March 2000, the HPSC Bravo Funding Corp. ("Bravo") revolving credit
facility (the "Bravo Facility") was amended under substantially the same terms
and conditions, providing the Company with available borrowings of up to
$347,500,000. As of March 31, 2000, Bravo had a total of $207,611,000
outstanding under the loan and sale portions of the Bravo Facility ($145,871,000
in loans and $61,740,000 in sales). Bravo incurs interest at various rates in
the commercial paper market and enters into interest rate swap agreements to
assure fixed rate funding. In connection with these borrowing and sales, Bravo
had a total of 41 separate interest rate swap contracts with BankBoston with a
total notional value of $207,000,000 at March 31, 2000. These interest rate
swaps are matched swaps, and as such, are accounted for using settlement
accounting. Monthly cash settlements on the swap agreements are recognized in
income as they accrue. In the case where the notional value of the interest rate
swap agreements significantly exceeds the outstanding underlying debt, the
excess swap agreements would be marked-to-market through income until new
borrowings are incurred which would be subject to such swap agreements. All
interest rate swap agreements entered into by the Company are for other than
trading purposes.

     4.   In April 1999, the Company, along with its wholly-owned, special
purpose subsidiary, HPSC Capital Funding, Inc. ("Capital"), signed an amended
Lease Receivable Purchase Agreement with EagleFunding Capital Corporation
("Eagle"). Pursuant to the terms of the revolving credit facility (the "Capital
Facility"), Capital had a total of $122,068,000 outstanding in loans and sales
($77,956,000 in loans and $44,112,000 in sales) at March 31, 2000, and in
connection with these borrowings and sales, had 22 separate interest rate swap
agreements with BankBoston with a total notional value of $118,887,000. These
interest rate swaps are matched swaps, and as such, are accounted for using
settlement accounting. Monthly cash settlements on the swap agreements are
recognized in income as they accrue. In the case where the notional value of the
interest rate swap agreements significantly exceeds the outstanding underlying
debt, the excess swap agreements would be marked-to-market through income until
new borrowings are incurred which would be subject to such swap agreements. All
interest rate swap agreements entered into by the Company are for other than
trading purposes.

     5.   On March 31, 2000, the Company had restricted cash of $10,476,000
under the Bravo Facility and $5,636,000 under the Capital Facility. All such
restricted cash is reserved for debt service.

     6.   In February 2000, the Company entered into an additional secured,
fixed rate, fixed term loan agreement with Springfield Institution for Savings.
The Company borrowed $9,324,000 under that agreement, subject to certain
recourse and performance covenants.

     7.   The Financial Accounting Standards Board ("FASB") issued SFAS No. 130,
"Reporting Comprehensive Income". This statement, adopted January 1, 1998,
established standards for reporting and presenting comprehensive income and its
components. Comprehensive income equals net income for each of the three month
periods ended March 31, 2000 and March 31, 1999.

11% of the total portfolio of that segment. The licensed professional financing
segment relies on certain vendors to provide referrals to the Company. For the
three months ended March 31, 2000, no one vendor accounted for greater than 8%
of the Company's licensed professional financing originations.

     9.   In June 1998, SFAS No. 133, "Accounting for Derivative Instruments and
Hedging Activities" was issued. This Statement establishes new accounting and
reporting standards for derivative instruments and for hedging activities. It
requires that an entity recognize all derivatives as either assets or
liabilities in the statement of financial position and measure those instruments
at fair value. This statement will be effective for the first quarter of the
Company's year ended December 31, 2001. The Company is evaluating the impact of
this statement on its consolidated results of operations.

                     MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                  FINANCIAL CONDITION AND RESULTS OF OPERATIONS

RESULTS OF OPERATIONS

     Earned income from leases and notes for the three months ended March 31,
2000 was $11,492,000 (including approximately $1,220,000 from the Company's
commercial lending subsidiary, American Commercial Finance Corporation ("ACFC"))
as compared to $9,260,000 (including approximately $1,173,000 from ACFC) for the
three months ended March 31, 1999. The increase of 24% was due primarily to an
increase in the net investment in leases and notes in 2000 over 1999, resulting
in part from a higher level of originations in the first quarter of 2000 of
$57,253,000 compared to $40,277,000 for the same period in 1999. Gains on sales
of leases and notes were $1,154,000 in the three months ended March 31, 2000
compared to $1,165,000 for the quarter ended March 31, 1999. The decrease was
due to higher levels of asset sales activity in 2000 of $24,166,000 compared to
$10,921,000 in 1999, offset by lower margins generated by the current year asset
sales.

     Interest expense (net of interest income) for the first quarter of 2000 was
$5,339,000 (46% of earned income) compared to $4,119,000 (44% of earned income)
in the comparable 1999 period. The increase in net interest expense was
primarily due to a 35% increase in average debt levels from March 31, 1999 to
March 31, 2000. These higher average debt levels resulted primarily from
borrowings to finance a higher level of contract originations. The increase in
percentage was due to higher interest rate borrowing costs during the most
recent three month period as compared to borrowing costs during the first three
months of the Company's prior fiscal year.

     Net financing margin (earned income less net interest expense) for the
first quarter of 2000 was $6,153,000 (54% of earned income) compared to
$5,141,000 (56% of earned income) for the first quarter of 1999. The increase in
amount was due to higher earnings on a higher balance of earning assets. The
decrease in percentage was due to higher interest rate borrowing costs during
the most recent three month period as compared to borrowing costs during the
first three months of the Company's prior fiscal year.

     The provision for losses for the first quarter of 2000 was $1,357,000 (12%
of earned income) compared to $749,000 (8% of earned income) in the first
quarter of 1999. The increases in amount and percentage were due to growth in
the portfolio, along with the Company's continuing evaluation of its portfolio
quality, delinquencies, loss history and allowance for losses.

     The allowance for losses at March 31, 2000 was $9,532,000 (2.5% of net
investment in leases and notes) compared to $9,150,000 (2.5% of net investment
in leases and notes) at December 31, 1999. Net charge offs for the three months
ended March 31, 2000 were $975,000 compared to $534,000 for the same period in
1999.

     Selling, general and administrative expenses for the three months ended
March 31, 2000 were $4,770,000 (42% of earned income) compared to $4,547,000
(49% of earned income) in the comparable 1999 period. The increase in amount was
caused by increased administrative costs required to support higher levels of
owned and serviced assets. The decrease in percentage of earned income resulted
primarily from increased productivity and the Company's continuing efforts to
control its operating expense growth rate.

     The Company's income before income taxes for the quarter ended March 31,
2000 was $1,180,000 compared to $1,010,000 in the same period in 1999. The
provision for income taxes was $487,000 (41% of income before income taxes) for
the three months ended March 31, 2000 compared to $416,000 (41% of income before
income taxes) for the same period in 1999.

     The Company's net income for the three months ended March 31, 2000 was
$693,000 ($0.16 diluted net income per share) compared to $594,000 ($0.14
diluted net income per share) for the three months ended March 31, 1999. The
increase resulted from higher earned income on leases and notes, offset by
higher selling, general and administrative costs, higher net interest costs, and
a higher provision for losses.

LIQUIDITY AND CAPITAL RESOURCES

     At March 31, 2000, the Company had $18,265,000 in cash, cash equivalents
and restricted cash as compared to $16,280,000 at December 31, 1999. As
described in Note 5 to the Company's condensed consolidated financial statements
included in this report on Form 10-Q, $16,112,000 was restricted pursuant to
financing agreements as of March 31, 2000, compared to $14,924,000 at December
31, 1999.


                                       8

     Cash provided by operating activities was $2,870,000 for the three months
ended March 31, 2000 compared to $2,128,000 for the three months ended March 31,
1999. The significant components of cash provided by operating activities for
the three months ended March 31, 2000 as compared to the same period in 1999
were an increase in the provision for losses of $1,357,000 compared to $749,000
for the same period in 1999, offset by gains on sales of lease contracts and
notes receivable of $1,154,000 in 2000 compared to $1,165,000 for the same
period in 1999.

     Cash used in investing activities was $22,378,000 for the three months
ended March 31, 2000 compared to $6,891,000 for the three months ended March 31,
1999. The significant components of cash used in investing activities for the
first three months of 2000 compared to the same period in 1999 were an increase
in originations of lease contracts and notes receivable due in installments to
$66,651,000 from $39,813,000 and an increase in notes receivable of $975,000
compared to a decrease of $3,114,000 in the prior year, offset by an increase in
portfolio receipts to $23,451,000 from $20,006,000, along with an increase in
proceeds from sales of lease contracts and notes receivable of $21,544,000 in
2000 compared to $9,829,000 in the comparable period ended March 31, 1999.

     Cash provided by financing activities for the three months ended March 31,
2000 was $20,305,000 compared to $7,358,000 for the three months ended March 31,
1999. The significant components of cash provided by financing activities for
the first three months of 2000 as compared to the equivalent period in 1999 were
an increase in proceeds from issuance of senior notes, net of debt issuance
costs, to $40,099,000 from $33,069,000, and net proceeds from revolving credit
borrowings of $4,000,000 in the first three months of 2000 compared to net
repayments of revolving credit borrowings of $8,000,000 in the same period in
1999, offset by higher repayments of senior notes of $24,932,000 for the three
months ended March 31, 2000 compared to $18,337,000 for the three months ended
March 31, 1999.

     In May 1999, the Company executed the Third Amendment to the Third Amended
and Restated Revolving Credit Agreement with BankBoston as the Agent Bank (the
"Revolver Agreement"). The Third Amendment to the Revolver Agreement provides
availability to the Company of $90,000,000 through May 2000. Under the Revolver
Agreement, the Company may borrow at variable rates of prime and at LIBOR plus
1.35% to 1.50% respectively, depending upon certain performance covenants. At
March 31, 2000, the Company had $74,000,000 outstanding under this facility and
$16,000,000 available for borrowing, subject to borrowing base limitations. The
outstanding borrowings under the Revolver Agreement are not hedged and,
therefore, are exposed to upward movements in interest rates. In May 2000, the
Company executed the Fourth Amended and Restated Revolving Credit Agreement,
providing the Company with available borrowings up to $90,000,000 under
substantially the same terms and conditions.

     In March 1997, the Company issued $20,000,000 of unsecured senior
subordinated notes due in 2007 ("Senior Subordinated Notes") bearing interest at
a fixed rate of 11% (the "Note Offering"). The Company received approximately
$18,300,000 in net proceeds from the Note Offering and used such proceeds to
repay amounts outstanding under the Revolver Agreement. The Senior Subordinated
Notes are redeemable at the option of the Company, in whole or in part, other
than through the operation of a sinking fund, after April 1, 2002 at established
redemption prices, plus accrued but unpaid interest to the date of repurchase.
Beginning July 1, 2002, the Company is required to redeem through sinking fund
payments, on January 1, April 1, July 1, and October 1 of each year, a portion
of the aggregate principal amount of the Senior Subordinated Notes at a
redemption price equal to $1,000,000 plus accrued but unpaid interest to the
redemption date.

     In April 1999, the Company, along with its wholly-owned, special purpose
subsidiary, HPSC Capital Funding, Inc. ("Capital"), signed an amended Lease
Receivable Purchase Agreement with EagleFunding Capital Corporation ("Eagle").
This revolving credit facility (the "Capital Facility") provides the Company
with available borrowings up to $125,000,000. Under the terms of the Capital
Facility, Capital, to which the Company may sell or contribute certain of its
portfolio assets from time to time, pledges or sells its interests in these
assets to Eagle, a commercial paper conduit entity. Capital may borrow at
variable rates in the commercial paper market and may enter into interest rate
swap agreements to assure fixed rate funding. Monthly settlements of the
borrowing base and any applicable principal and interest payments are made from
collections of Capital's portfolio. The Company is the servicer of the Capital
portfolio subject to certain covenants. The required monthly payments of
principal and interest to purchasers of the commercial paper are guaranteed by
BankBoston pursuant to the terms of the facility. At March 31, 2000, the Company
had $44,112,000 outstanding from sales of receivables and $77,956,000 of
borrowings outstanding from loans under the Capital Facility. In connection with
this facility, the Company had 22 separate interest rate swap agreements with
BankBoston with a total notional value of $118,887,000.

     In June 1998, the Company, along with its wholly-owned, special-purpose
subsidiary HPSC Bravo Funding Corp. ("Bravo"), signed an amended revolving
credit facility (the "Bravo Facility") structured and guaranteed by MBIA, Inc.,
providing the Company with available borrowings up to $225,000,000. In March
2000, the Bravo Facility was amended on substantially the same terms and
conditions, providing the Company with available borrowings up to $347,500,000.
Under the terms of the Bravo Facility, Bravo, to


                                       9
<PAGE>   10


which the Company sells and may continue to sell or contribute certain of its
portfolio assets subject to certain covenants regarding Bravo's portfolio
performance and borrowing base calculations, pledges or sells its interests in
these assets to a commercial paper conduit entity. Bravo incurs interest at
variable rates in the commercial paper market and enters into interest rate swap
agreements to assure fixed rate funding. Monthly settlements of principal and
interest payments are made from the collection of payments on Bravo's portfolio.
The Company is the servicer of the Bravo portfolio, subject to meeting certain
covenants. The required monthly payments of principal and interest to purchasers
of the commercial paper are guaranteed by MBIA pursuant to the terms of the
facility. At March 31, 2000, Bravo had $61,740,000 outstanding from sales of
receivables under the sale accounting portion of the Bravo Facility and
$145,871,000 of indebtedness outstanding under the loan portion of the Bravo
Facility. In connection with this facility, the Company had 41 separate interest
rate swap agreements with BankBoston with a total notional value of
$207,000,000.

     In February 2000, the Company entered into an additional fixed rate, fixed
term loan agreement with Springfield Institution for Savings ("SIS"). The
Company borrowed $9,324,000, subject to certain recourse and performance
covenants. The Company had $14,112,000 outstanding under all loan agreements
with SIS at March 31, 2000.

     Management believes that the Company's liquidity, resulting from the
availability of credit under the Revolver Agreement, the Bravo Facility, the
Capital Facility, the Senior Subordinated Notes, and loans from various savings
banks, along with cash obtained from the sales of its financing contracts and
from internally generated revenues, is adequate to meet current obligations and
future projected levels of financings and to carry on normal operations. In
order to finance adequately its anticipated growth, the Company will continue to
seek to raise additional capital from bank and non-bank sources, make selective
use of asset sale transactions and use its current credit facilities. The
Company expects that it will be able to obtain additional capital at competitive
rates, but there can be no assurance it will be able to do so.

                                   ARTICLE II
                       AMOUNTS AND TERMS OF THE PURCHASES

          SECTION 2.01. AGREEMENT TO SELL AND CONTRIBUTE. On the terms and
conditions hereinafter set forth, the Seller hereby agrees, from time to time
until the Termination Date, to sell in part and to contribute in part to the
Buyer, and the Buyer hereby agrees, from time to time until the Termination
Date, to purchase and acquire from the Seller, all of the Seller's right, title
and interest in, to and under the Receivables, the Contracts, all Equipment, all
Related Security with respect to the foregoing, and all Collections and other
proceeds of the foregoing. Except as provided in the immediately succeeding
sentence, nothing contained in this Agreement is intended to, nor shall it be
deemed to, constitute a commitment on the part of the Seller or on the part of
the Buyer to consummate any Purchase hereunder, it being understood that all
such Purchases shall be made at the discretion of each such party but otherwise
subject to the terms and conditions set forth herein. Notwithstanding the
foregoing, the Buyer agrees, subject to the satisfaction of the conditions set
forth in SECTION 3.02, to consummate any Purchase requested by the Seller
pursuant to SECTION 2.02(b) for which the notice of purchase specifies that the
entire Purchase Price shall be paid as a contribution to the Buyer's capital and
not in cash. Nothing contained in this Agreement is intended to, nor shall it be
deemed to, constitute an assumption by the Buyer of any obligation under any
Contract, all of which obligations shall be retained by the Seller, and the
Seller hereby agrees to perform all such obligations.

          (a) It is the intent of the Seller and the Buyer that the transfer by
the Seller to the Buyer of the Transferred Assets constitute a sale, in part,
and a contribution to capital, in part, which sales and contributions are
absolute and irrevocable, without recourse except as otherwise provided in this
Agreement, and will provide the Buyer with full ownership of the Transferred
Assets. Each of Seller and the Buyer hereby agrees to treat such transfer as a
sale and a contribution for tax, reporting and accounting purposes (except to
the extent that such transfer is not recognized due to the reporting of taxes on
a consolidated basis where applicable and the application of consolidated
financial reporting principles under GAAP). The Seller agrees to respond to any
inquiries with respect to the transfer hereunder by confirming the sale and
contribution of the Receivables, Contracts and the Equipment to the Buyer, and
to note on its financial statements that such Receivables, Contracts and
Equipment have been sold and/or contributed to the Buyer.

          SECTION 2.02. PURCHASES FROM THE SELLER. On the Closing Date, the
Seller shall sell to the Buyer, and the Buyer shall purchase from the Seller,
all of the Transferred Assets arising under or in connection with the Contracts
described on EXHIBIT A hereto in consideration of which the Buyer will pay to
the Seller $8,000.000 in cash. The remaining portion of such Transferred Assets
shall be a contribution to the capital of the Buyer in return for 999 shares of
the capital stock of the Buyer.


                                       2

<PAGE>   7

          (a) Each Purchase subsequent to the Closing Date shall be made on a
Settlement Date upon not less than three Business Days' prior written notice to
the Buyer requesting such Purchase, which notice shall contain a supplemental
EXHIBIT A hereto setting forth a list of the Contracts to be transferred to the
Buyer on such Settlement Date. Each such notice of a proposed Purchase shall
accompany a Settlement Report and shall specify that portion of the Purchase
Price which is payable in cash for the Transferred Assets to be transferred.
Such notice shall be accompanied by a certification from the Seller that, after
giving effect to the Purchase proposed in such notice, the conditions set forth
in SECTION 3.02 hereto shall have been satisfied. The purchase price (the
"PURCHASE PRICE") for the new Transferred Assets included in any Purchase shall
be agreed to in writing by the Buyer and the Seller on or before the applicable
Settlement Date and shall be an amount not less than 95% nor more than 100%
TIMES the aggregate Discounted Receivables Balance of the Receivables included
in such Purchase.

          (b) Except as otherwise provided below in this SECTION 2.02, the
Purchase Price for the Transferred Assets sold by the Seller under this
Agreement shall be payable in full in cash by the Buyer, in each case on the
date of each such Purchase, except that the Buyer may, with respect to any
Purchase, offset against such Purchase Price any amounts owed by the Seller to
the Buyer hereunder and which remain unpaid. On the date of each Purchase, the
Buyer shall, upon satisfaction of the applicable conditions set forth in ARTICLE
III, make available to the Seller the portion of the Purchase Price payable in
cash referred to above in same day funds.

          (c) If, on any Settlement Date, the Buyer has insufficient funds to
pay in full the Purchase Price owed on such day, then the Buyer shall so notify
the Seller prior to consummating such Purchase and the Seller shall, by
accepting the cash proceeds tendered by the Buyer, be deemed to have contributed
to the capital of the Buyer Transferred Assets having a Purchase Price equal to
the otherwise unpaid portion of the total Purchase Price otherwise owed on such
day.

          (d) Promptly after each Purchase hereunder (including the initial
Purchase), the Seller will send to each Obligor under the Contracts included in
such Purchase, with the next invoice sent to such Obligor, a Notice of
Assignment, substantially in the form attached hereto as EXHIBIT B, which shall,
inter alia, advise such Obligor of the absolute transfer by the Seller to the
Buyer of that Obligor's Contract, including the Receivables due thereunder, and
any related Equipment.

          SECTION 2.03. SERVICING OF CONTRACTS AND EQUIPMENT. In connection with
the contribution, assignment, transfer, sale and conveyance of the Transferred
Assets to the Buyer, the Seller hereby agrees to service the Contracts and
Equipment for the benefit of the Buyer and its successors and assigns in
accordance with the terms and provisions of ARTICLE VI hereof.

          SECTION 2.04. TRANSFER OF RECORDS. (a) The transfer of Transferred
Assets hereunder shall include the transfer to the Buyer of all of the Seller's
right and title to and interest in the Records relating to such Transferred
Assets, which transfer shall be effected automatically


                                       3

<PAGE>   8


on the Purchase Date for such Transferred Assets without any further
documentation. In connection with such transfer, the Seller hereby grants to the
Buyer an irrevocable, non-exclusive license to use, without royalty or payment
of any kind, all software used by the Seller to account for the Receivables and
the Contracts, to the extent necessary to administer the Transferred Assets,
whether such software is owned by the Seller or is owned by others and used by
the Seller under license agreements with respect thereto, such use to be subject
to the terms and conditions of any such license agreements with third parties
where applicable. The license granted hereby shall be irrevocable, and shall
terminate on the date on which the aggregate Receivables Balance shall have been
reduced to zero.

          (b) The Seller shall take such action requested by the Buyer, from
time to time hereafter, that may be necessary or appropriate to ensure that the
Buyer and its assigns have (i) an enforceable ownership interest in the Records
relating to the Transferred Assets and (ii) an enforceable right (whether by
license or sublicense or otherwise) to use all of the computer software used to
account for the Transferred Assets and/or to recreate such Records, such use to
be subject to the terms and conditions of any license agreements with third
parties pursuant to which the Seller has the right to use the applicable
computer software.

          SECTION 2.05. COLLECTIONS; DEEMED COLLECTIONS. (a) Any Collections of
Receivables received (or deemed to have been received) by the Seller shall be
remitted directly to the Buyer by depositing such Collections in the Lock-box
Account within one Business Day of Seller's receipt.

(b) If on any day the Outstanding Balance of any Receivable is either (i)
reduced or adjusted as a result of any defective, rejected, returned,
repossessed or foreclosed merchandise, any defective or rejected services, any
cash discount or any other adjustment made or performed by the Seller or any
other Person (including, without limitation, those described in the definition
of "DILUTION FACTORS"), or (ii) reduced or cancelled as a result of a setoff in
respect of any claim by the Obligor thereof against the Seller or any other
Person (whether such claim arises out of the same or a related transaction or an
unrelated transaction), the Seller shall be deemed to have received on such day
a Collection of such Receivable in the amount of such reduction, cancellation or
adjustment. If on any day any of the representations or warranties in the first
sentence of SECTION 4.01(h) is no longer true with respect to a Receivable or if
the Seller has breached its obligations under SECTION 5.01(j), then the Seller
shall be deemed to have received on such day a Collection of such Receivable:
(x) if such representation, warranty or covenant relates to the non-existence of
any Adverse Claims, the Seller shall be deemed to have received a Collection of
such Receivable in the dollar amount of the Adverse Claims attaching thereto and
(y) if such representation or warranty relates to the validity or perfection of
the transfer of such Receivable under this Agreement or the perfection of the
Buyer's security interest in any Equipment as against the Obligor thereunder,
then the Seller be deemed to have received a Collection of such Receivable in an
amount equal to the Outstanding Balance thereof. To the extent that any such
deemed Collection reduces the Outstanding Balance of such Receivable to zero,
then, upon the Seller's payment to the Buyer of such deemed Collection, the
Buyer shall re-assign to the Seller all of its right, title and interest in and
to the relevant


                                       4

<PAGE>   9

Receivable, the Contract under which such Receivable arose and the Related
Security relating thereto. Prior to the 15th day of each month (or if such day
is not a Business Day, the immediately succeeding Business Day), the Seller
shall prepare and forward to the Buyer, a Settlement Report as of the close of
business of the Seller on the last day of the immediately preceding month, in
substantially the form set forth in EXHIBIT C.

          (c) Although the Seller and the Buyer agree that the Seller (except in
its capacity as Servicer pursuant to SECTION 6.02(a)), shall have no right to so
terminate, reject or not assume a Contract, if the Seller in its capacity as
Servicer (or its successor in interest, including a trustee appointed under the
Bankruptcy Code) terminates, rejects or does not assume a Contract, in whole or
in part, prior to the expiration of the original term of such Contract, whether
such rejection, termination or non-assumption is made pursuant to an equitable
cause, statute, regulation, judicial proceeding or other applicable law
(including, without limitation, Section 365 of the Bankruptcy Code), then (i)
the Seller shall be deemed to have received Collections with respect to
Receivables arising under such Contract in an amount equal to (A) in the event
of a prepayment or termination consented to by the Seller at the Obligor's
request, the excess, if any, of the Termination Amount over all amounts paid by
the Obligor on account of such termination or (B) in the event of any other
rejection or non-assumption, the amount, of the Outstanding Balance thereof that
has not been, or may not be paid as a result of such rejection, termination or
non-assumption. Upon the Seller's payment of any such deemed Collections
described in this SECTION 2.05(c), the Buyer shall re-assign to the Seller all
of its right, title and interest in and to the relevant Receivable or
Receivables, the Contracts under which such Receivable(s) arose and the Related
Security relating thereto.

          SECTION 2.06. PAYMENTS AND COMPUTATIONS, ETC. Except as otherwise
provided herein, all amounts to be paid or deposited by the Seller hereunder
shall be paid or deposited in accordance with the terms hereof no later than
11:00 A.M. (New York City time) on the day when due in lawful money of the
United States of America in immediately available funds to a special account in
the name of Buyer and maintained at Bank of Boston. The Seller shall, to the
extent permitted by law, pay to the Buyer interest on all amounts not paid or
deposited when due hereunder (whether owing by the Seller individually or as
Servicer) at 2% per annum above the Base Rate, payable on demand; PROVIDED,
HOWEVER, that such interest rate shall not at any time exceed the maximum rate
permitted by applicable law. All computations of interest and other fees
hereunder shall be made on the basis of a year of 360 days for the actual number
of days (including the first but excluding the last day) elapsed.

          SECTION 2.07. PERFECTION OF LIENS; FURTHER ASSURANCES. Upon the
request of the Buyer, the Seller shall, at its expense, promptly execute and
deliver all further instruments and documents, and take all further action
(including, without limitation, the execution and filing of such financing or
continuation statements, or amendments thereto or assignments thereof), that may
be necessary or desirable, or that the Buyer may request, in order to (i)
perfect and protect any security interest granted or purported to be granted by
an Obligor under any Contract and (ii) perfect and protect any ownership or
security interest granted or purported to be granted to the Buyer hereunder or
(iii) to enable the Buyer to exercise and enforce its rights and remedies


                                       5

<PAGE>   10


hereunder with respect to any Transferred Assets; PROVIDED that the Seller shall
not be required to file financing statements or to maintain the effectiveness of
previously filed financing statements with respect to any Receivables the
Outstanding Balance of which originally is or has thereafter been reduced below
$5,000, respectively, so long as the aggregate Outstanding Balance of
Receivables for which no such financing statements are in effect at any time
remains less than 7.5% of the Discounted Eligible Receivables Balance at such
time; PROVIDED that such seven and one-half percent limitation shall not apply
from and after the Termination Date unless and to the extent that the Buyer or
the Collateral Agent on its behalf specifically requests otherwise.

                                  ARTICLE III

PROVIDED, HOWEVER, that the Buyer shall not be deemed to have waived any claim
it may have under this Agreement for the failure by the Seller in fact to
satisfy any such condition precedent.

connection herewith constitute the legal, valid and binding obligations of the
Seller enforceable against the Seller in accordance with their respective terms,
except as enforceability may be limited by bankruptcy, insolvency or similar
laws relating to or affecting creditors' rights generally and by equitable
principles.

          (e) FINANCIAL STATEMENTS. (i) The consolidated balance sheets of the
Seller and its consolidated Subsidiaries as at December 31, 1998, and the

Deloitte & Touche, independent public accountants, and the unaudited interim
consolidated balance sheets of the Seller and its subsidiaries as of June 30,
1999 and September 30, 1999 and the related consolidated statements of income,
retained earnings and cash flows for the six months and nine months,
respectively, ending on such dates (the "Interim Financials"), in each case

consolidated Subsidiaries as at such dates and the consolidated results of the
operations of the Seller and its consolidated Subsidiaries for the period ended
on such dates, all in accordance with GAAP, and since December 31, 1998, there
has been no material adverse change in any such condition or operations, except

                                       8
<PAGE>   13

          (f) NO LITIGATION. There are no actions, suits or proceedings pending,
or to the knowledge of the Seller threatened, against or affecting the Seller or
any of its Subsidiaries, or the property of the Seller or any of its
Subsidiaries, in any court, or before any arbitrator of any kind, or before or
by any governmental body, which may materially adversely affect (i) the
business, properties, operations, prospects, profits or condition (financial or
otherwise) financial condition of the Seller or (ii) the ability of the Seller
to perform its obligations under this Agreement or the Certificate or (iii) the
collectibility of the Receivables. Neither the Seller nor any of its
Subsidiaries is in default with respect to any order of any court, arbitrator or
governmental body except for defaults with respect to orders of governmental
agencies which defaults are not material to the business or operations of the
Seller or any of its Subsidiaries or the Seller's ability to perform its
obligations hereunder.

          (g) USE OF PROCEEDS. No proceeds of any Purchase will be used by the
Seller to acquire any security in any transaction which is subject to Section 13
or 14 of the Securities Exchange Act of 1934, as amended.

          (h) PERFECTION OF INTEREST IN TRANSFERRED ASSETS. Prior to the Buyer's
Purchase and/or acquisition of each Transferred Asset hereunder, the Seller is
or will be the lawful owner of, and have good title to, such Transferred Asset
free and clear of any Adverse Claim and upon each Purchase and/or acquisition by
the Buyer of Transferred Assets hereunder, the Buyer shall acquire a valid and
perfected first priority ownership interest in each Receivable then existing or
thereafter arising and in the Related Security, the other Transferred Assets and
Collections and with respect thereto, in each case free and clear of any Adverse
Claim. All such Purchases of Receivables and related Transferred Assets
constitute true and valid sales, and all such Purchases and contributions of
Receivables and related Transferred Assets constitute true and valid transfers
and assignments of all of Seller's right, title and interest in, to and under
such Transferred Assets (and not merely a pledge of such Receivables and related
Transferred Assets for security purposes), enforceable against creditors of the
Seller and no such Transferred Assets shall constitute property of the Seller;
and no effective financing statement or other instrument similar in effect
covering any Receivable, the Related Security, Collections or the other
Transferred Assets shall at any time be on file in any recording office except
such as may be filed in favor of the Buyer (or its assignees) in accordance with
this Agreement.

          (i) ACCURACY OF INFORMATION. No Settlement Report (if prepared by the
Seller, or to the extent that information contained therein is supplied by the
Seller), information, exhibit, financial statement, document, book, record or
report (other than forecasts required to be delivered by the Seller hereunder)
furnished or to be furnished by the Seller to the Buyer in connection with this
Agreement is or shall be inaccurate in any material respect as of the date it is
or shall be dated or (except as otherwise disclosed to the Buyer, as the case
may be, at such time) as of the date so furnished, or contains or shall contain
any material misstatement of fact or omits or shall omit to state a material
fact or any fact necessary to make the statements contained therein not
materially misleading.

                                       9

<PAGE>   14

          (j) LOCATION OF CHIEF EXECUTIVE OFFICE AND RECORDS. The chief place of
business and chief executive office of the Seller are located at the address of
the Seller referred to in SECTION 9.02 hereof and the locations of the offices
where the Seller keeps all the Records are listed on EXHIBIT F (or at such other
locations, notified to the Buyer in accordance with SECTION 5.01(f), in
jurisdictions where all action required by SECTION 6.03 has been taken and
completed).

          (k) LOCK-BOX ACCOUNTS. Each Obligor under a Contract has, within one
month of the date of Purchase of such Contract, been instructed to remit payment
on the Receivables to a Post Office Box for remittance to a Lock-Box Account or
directly to a Lock-Box Account substantially in the form of EXHIBIT G. From and
after the Closing Date, the Seller will have no right, title and/or interest to
any of the Lock-Box Accounts and will maintain no lock-box accounts in its own
name for the collection of such Receivables. The Seller has delivered to the
Collateral Agent a duplicate key to each Post Office Box and has filed a
standing delivery order with the United States Postal Service authorizing the
Collateral Agent to receive mail delivered to each such Post Office Box. The
account numbers of all Lock-Box Accounts, together with the names and addresses
of all the Lock-Box Banks maintaining such Lock-Box Accounts and the related
Post Office Boxes, are specified in EXHIBIT H.

          (l) NO TRADE NAMES. Except as described in EXHIBIT I, the Seller has
no trade names, fictitious names, assumed names or "doing business as" names.


          (m) SEPARATE CORPORATE EXISTENCE. The Seller is entering into the
transactions contemplated by this Agreement in reliance on the Buyer's identity
as a separate legal entity from the Seller and each of its Affiliates other than
the Buyer, and acknowledges that the Buyer and the other parties to the Facility
Documents are similarly entering into the transactions contemplated by the other
Facility Documents in reliance on the Buyer's identity as a separate legal
entity from the Seller and each such other Affiliate.

          (n) TAXES. The Seller has filed or caused to be filed all Federal,
state and local tax returns which are required to be filed by it, and has paid
or caused to be paid all taxes shown to be due and payable on such returns or on
any assessments received by it, other than any taxes or assessments, the
validity of which are being contested in good faith by appropriate proceedings
and with respect to which the Seller has set aside adequate reserves on its
books in accordance with GAAP and which have not given rise to any Adverse
Claims.

          (o) SOLVENCY. The Seller (i) is not "insolvent" (as such term is
defined in ss.101(32)(A) of the Bankruptcy Code, (ii) is able to pay its debts
as they mature; and (iii) does not have unreasonably small capital for the
business in which it is engaged or for any business or transaction in which it
is about to engage.

          (p) NO FRAUDULENT CONVEYANCE. The transactions contemplated by this
Agreement and by each of the Facility Documents are being consummated by the
Seller in furtherance of the Seller's ordinary business, with no contemplation
of insolvency and with no intent to hinder, delay or defraud any of its present
or future creditors. By its receipt of the

                                       10

<PAGE>   15


Purchase Prices hereunder and its ownership of the capital stock of the Buyer,
the Seller shall have received reasonably equivalent value for the Transferred
Assets sold or otherwise conveyed to the Buyer under this Agreement.

          (q) SOFTWARE. Attached as EXHIBIT J is a list of all computer software
used by the Seller to administer the Receivables and other Transferred Assets.
Each of the Buyer and the Collateral Agent, as assignee of the Buyer, has (or
will have, concurrently with the effectiveness hereof) an enforceable right
(whether by license, sublicense or assignment) to use all of the computer
software used to account for the Transferred Assets to the extent necessary to
administer the Receivables and other Transferred Assets, such use to be subject
to the terms and conditions of any license agreement for such software between
the Seller and any third parties where applicable.

          (r) REPRESENTATIONS WITH RESPECT TO RECEIVABLES AND CONTRACTS. With
respect to each Receivable:

               (i) Each such Receivable, at the time of Purchase thereof, is an
               Eligible Receivable. Each Contract relating to a Receivable: (a)
               if it constitutes a Lease, is in substantially the form of
               EXHIBIT K-1 hereto; (b) if it constitutes a Finance Agreement, is
               in substantially the form of EXHIBIT K-2 hereto; (c) if it
               constitutes a Leasehold Improvement Note, is in substantially the
               form of EXHIBIT K-3 hereto; (d) if it constitutes a Practice
               Finance Loan, is in substantially the form of EXHIBIT K-4 hereto,
               and (e) if it constitutes a Non-Medical Contract, is in
               substantially the form of EXHIBIT K-1, EXHIBIT K-2, EXHIBIT K-3
               or EXHIBIT K-4 hereto.

               (ii) There are no facts or circumstances existing as of the
               Purchase Date thereof which give rise to any right of rescission,
               offset, counterclaim or defense, including the defense of usury,
               to the obligations of any Obligor, including the obligation of
               such Obligor to pay all amounts due thereunder, with respect to
               any Contract to which such Obligor is a party; and neither the
               operation of any of the terms of any Contract nor the exercise of
               any right thereunder will render such Contract unenforceable in
               whole or in part or subject to any right of rescission, offset,
               counterclaim or defense, including the defense of usury (other
               than limitations on enforcement which may subsequently arise as a
               result of bankruptcy, insolvency, reorganization or similar laws
               relating to or affecting the enforcement of creditors, rights
               generally and by general equitable principles), and no such right
               of rescission, offset, counterclaim or defense has been asserted
               with respect thereto.

               (iii) As of the Cut-Off Date, (i) the aggregate Discounted
               Receivables Balance of Contracts that are Leases is $5,239,644,
               (ii) the aggregate Discounted Receivables Balance of Contracts
               that are Finance Agreements


                                       11
<PAGE>   16


               pursuant to which the Buyer finances an Obligor's purchase of
               Equipment is $2,963,452, (iii) the aggregate Discounted
               Receivables Balance of Contracts that are Leasehold Improvement
               Notes is $1,439,116 and (iv) the aggregate discounted book value
               of anticipated residuals on the Equipment subject to Leases is,
               net of security deposits, $290,283.

               (iv) Each Lease requires the Obligor to assume all risk of loss
               or malfunction of the related Equipment. Each Lease and Finance
               Agreement pursuant to which the Buyer finances an Obligor's
               purchase of Equipment requires the Obligor to pay all sales, use,
               property, excise and other similar taxes imposed on or with
               respect to the related Equipment and permits the rights with
               respect to such Contract, and all collateral related thereto, to
               be assigned by the Seller without the consent of any Person. No
               Contract permits early termination or prepayment, unless the
               amount required to be paid by or on behalf of Obligor in respect
               thereof is equal to or greater than the applicable Termination
               Amount. No Contract provides for the substitution, exchange or
               addition of any Equipment subject thereto which would result in
               any reduction of the amount of payments or change the timing of
               payments due under such Contract.

               (v) Each Lease requires the related Obligor to maintain the
               related Equipment, if any, in good and workable order. Each Lease
               and Finance Agreement pursuant to which the Buyer finances an
               Obligor's purchase of Equipment requires the related Obligor to
               obtain and maintain physical damage insurance on the Equipment
               subject thereto and to name the lessor or lender thereunder as
               loss payee and an additional insured with respect thereto. The
               Collateral Agent is named as loss payee under all physical damage
               insurance on the Equipment that is carried by the Seller or the
               Buyer. To the best of Seller's knowledge, the Equipment was
               properly delivered to the Obligor in good repair, without defects
               and in satisfactory order and the related Equipment, if any, is
               in good operating condition and repair. To the best of the
               Seller's knowledge, the related Equipment was accepted by the
               Obligor after reasonable opportunity to inspect and test the same
               and no Obligor has informed the Seller of any defects therein.

               (vi) On each Purchase Date, after giving effect to the Purchases
               to be made on such date, the aggregate Discounted Receivables
               Balance of all Contracts with Obligors located in any one state
               does not exceed 30% of the Discounted Receivables Balance for all
               Contracts.

               (vii) On the Cut-Off Date, the Weighted Average Remaining Term of
               the Contracts included in the initial Purchase was 49 months. On
               each subsequent Purchase Date, after giving effect to the
               Purchases to be made


                                       12

<PAGE>   17

               on such date, the Weighted Average Remaining Term does not exceed
               57 months.

               (viii) On the Cut-Off Date, the lowest Outstanding Balance of the
               Receivables under any Contract included in the Purchases to be
               made on such date is no less than $224 and the highest
               Outstanding Balance of the Receivables under any Contract
               included in the Purchases to be made on such date is no greater
               than $130,667. As of each Purchase Date, after giving effect to
               the Purchases to be made on such date, the average Outstanding
               Balance of the Receivables is no greater than $30,000.

               (ix) As of the Purchase Date thereof, the Seller has delivered
               the Contract File for the related Contract to the Buyer or to the
               Custodian on the Buyer's behalf together with duly executed
               instruments of transfer or assignment in blank for each Contract
               constituting an instrument or chattel paper.

               (x) As of the Purchase Date thereof, the average original terms
               of the Contracts included in such Purchase does not exceed 4.75
               years.

               (xi) As of the Purchase Date thereof, the excess of (i) the
               average implicit interest rates being charged to Obligors in
               respect of the Receivables then being purchased OVER (ii) the
               Discount Rate applicable to such Receivables, shall not be
               greater than eight percent (8.0%).

          (s) OTHER INDEBTEDNESS. The Seller is not in default under any
material indenture, loan or credit agreement with respect to any Indebtedness,
the effect of which is to cause, or which would, with the giving of notice of
the lapse of time or both, permit the holder or holders thereof to cause, such
Indebtedness to become due prior to its stated maturity.

          (t) INVESTMENT COMPANY. The Seller is not an "investment company" or a
company controlled by an "investment company" within the meaning of the
Investment Company Act of 1940.

          (u) ERISA. Neither the Seller nor any of its ERISA Affiliates
maintains, contributes to or has any obligation to contribute to any Plan which
could reasonably be expected to, individually or in the aggregate, materially
adversely affect the ability of the Seller to perform its obligations under this
Agreement or any other Facility Document to which it is a party or which could
expose the Buyer to any material liability under ERISA. No accumulated or waived
funding deficiency (as defined in Section 302(a)(2) of ERISA or Section 412(a)
of the Internal Revenue Code) exists with respect to any Benefit Plan, and the
Seller has not failed to satisfy the minimum funding requirements under ERISA or
the Internal Revenue Code with respect to any Benefit Plan. Neither the Seller
nor any of its ERISA Affiliates has incurred any liability to or on account of a
Benefit Plan or Multiemployer Plan pursuant to Section 515, 4062, 4063, 4064,
4201 or 4204 of ERISA or expects to incur any liability under any of the
foregoing sections on

                                       13

<PAGE>   18

account of the termination of participation in or contributions to any such Plan
or Multiemployer Plan.

          (v) SELECTION OF RECEIVABLES. Each Receivable has been randomly
selected from the Originator's portfolio of receivables in accordance with its
normal standards and procedures used for all of its standard securitization
transactions and no selection procedures adverse to Triple-A have been employed
in such selections.

          (w) HISTORIC LOSS DATA. Attached hereto as a part of EXHIBIT D is a
summary of historical static loss data of the Originator suffered as a result of
charge-offs of the Originator's receivables, which summary is true and accurate
with respect to the periods described therein and does not omit any information
necessary to make such summary not misleading.

          (x) NON-MEDICAL CONTRACTS. On each Purchase Date, after giving effect
to the Purchases to be made on such date, the aggregate Discounted Receivables
Balance of all Non-Medical Contracts does not exceed 10% of the Discounted
Receivables Balance for all Contracts.

                                   ARTICLE V
                         GENERAL COVENANTS OF THE SELLER

corporate existence, rights, franchises and privileges in the jurisdiction of

(ii) the collectibility of any Receivable, (iii) the business, properties,
operations, prospects, profits or condition (financial or otherwise) condition
of the Seller or (iv) the ability of the Seller (individually or as Servicer) to

          (c) AUDITS. At any time and from time to time upon prior written
notice to the Seller and during regular business hours and on a quarterly basis

United States where all action required by SECTION 2.08 and by SECTION 6.04
shall have been taken and completed.

shall receive any Collections (including, without limitation, any Collections
deemed to have been received pursuant to SECTION 2.05), the Seller shall hold
such Collections in trust for the benefit of the Buyer and remit such
Collections to the Buyer by depositing such Collections into a Lock-Box Account
within one Business Day following Seller's identification thereof and in any
event within four Business Days following Seller's receipt thereof.

          (i) COMPLIANCE WITH ERISA. Establish, maintain and operate all Plans
to comply in all material respects with the provisions of ERISA, the IRC, and
all other applicable laws, and the regulations and interpretations thereunder.

          (j) PERFECTED SECURITY INTEREST UNDER CONTRACTS. Take such action with
respect to each Receivable as is necessary to ensure that the Buyer maintains,
as against the Obligor thereunder, a perfected security interest in any
Equipment relating thereto free and clear of Adverse Claims or, in the case of
any Lease, to ensure that the Buyer would maintain such a perfected priority
security interest in the event that a court or other Person were to determine
that such Lease purported to transfer to the Obligor an ownership (rather than a
leasehold) interest in the Equipment subject thereto; PROVIDED, that the Seller
shall not be required to file financing statements or to maintain the
effectiveness of previously filed financing statements with respect


                                       15
<PAGE>   20


to any Receivables the Outstanding Balance of which originally is or has
thereafter been reduced below $5,000, respectively, so long as the aggregate
Outstanding Balance of Receivables for which no such financing statements are in
effect at any time remains less than 7.5% of the Discounted Receivables Balance
of all Receivables at such time; PROVIDED that such seven and one-half percent
limitation shall not apply from and after the Termination Date unless and to the
extent that the Buyer or the Collateral Agent on its behalf specifically
requests otherwise.

          (k) MAINTENANCE OF INSURANCE. Maintain, or cause each Obligor to
maintain, with respect to the Contracts and the Equipment related thereto,
casualty and general liability insurance which provide at least the same
coverage as a fire and extended coverage insurance policy as is comparable for
other companies in related businesses. Such insurance policies (and
self-insurance where permitted) shall be maintained in an amount which is not
less than the Discounted Value for the Receivables arising under the relevant
Contracts. Each such casualty and liability policy if maintained by an Obligor,
shall name the Seller or the Buyer as loss payee and additional insured and the
Seller shall have assigned any such interest to the Buyer. The Seller shall
remit, or shall cause to be remitted, the proceeds of any such insurance policy
to a Lock-Box Account.

          (l) SEPARATE IDENTITY. Take all actions required to maintain the
Buyer's status as a separate legal entity, including, without limitation, (i)
not holding the Buyer out to third parties as other than an entity with assets
and liabilities distinct from the Seller and the Seller's other Subsidiaries;
(ii) not holding itself out to be responsible for the debts of the Buyer or,
other than by reason of owning capital stock of the Buyer, for any decisions or
actions relating to the business and affairs of the Buyer; (iii) causing any
financial statements consolidated with those of the Buyer to address (by
footnote or otherwise and in language reasonably satisfactory to the Buyer and
the Collateral Agent) the separate corporate existence of the Buyer and the
Buyer's ownership of the Receivables; (iv) taking such other actions as are
necessary on its part to ensure that all corporate procedures required by its
and the Buyer's respective certificates of incorporation and by-laws are duly
and validly taken; (v) keeping correct and complete records and books of account
and corporate minutes; (vi) not acting in any other matter that could
foreseeably mislead others with respect to the Buyer's separate identity; and
(vii) taking such other actions as may be necessary on its part to ensure that
the Buyer is in compliance at all times with SECTION 5.01(l) of the Credit
Agreement and SECTION 5.01(l) of the Triple-A Purchase Agreement.

          (m) TAXES. File or cause to be filed, and cause each of its
Subsidiaries with whom it shares consolidated tax liability to file, all
federal, state and local tax returns which are required to be filed by it,
except where the failure to file such returns could not reasonably be expected
to have a material adverse effect on the collectibility of the Transferred
Assets or the ability of the Seller to perform its obligations hereunder or
under any other Facility Document to which it is a party or which could
otherwise be reasonably expected to expose the Buyer to a material liability.
The Seller shall pay or cause to be paid all taxes shown to be due and payable
on such returns or on any assessments received by it, other than any taxes or
assessments, the validity of which are being contested in good faith by
appropriate proceedings and with respect

                                       16

<PAGE>   21


to which the Seller or the applicable subsidiary shall have set aside adequate
reserves on its books in accordance with GAAP and which proceedings could not
reasonably be expected to have a material adverse effect on the collectibility
of the Transferred Assets or the ability of the Seller to perform its
obligations hereunder or under any other Facility Document to which it is a
party or which could otherwise be reasonably expected to expose the Buyer to a
material liability.

          (n) SEGREGATION OF COLLECTIONS. Prevent the deposit into any of the
Lock-Box Accounts of any funds other than Collections in respect of the
Transferred Assets and, to the extent that any such funds are nevertheless
deposited into any of such Lock-Box Accounts, promptly identify any such funds
to the Servicer for segregation and remittance to the owner thereof.

          SECTION 5.02. REPORTING REQUIREMENTS OF THE SELLER. From the Closing
Date until the later of the Termination Date or the Collection Date, the Seller
will, unless the Buyer shall otherwise consent in writing, furnish to the Buyer:

officer or treasurer of the Seller setting forth details of such Event of
Termination or event and the action which the Seller proposes to take with
respect thereto;

          (f) promptly, from time to time, such other information, documents,
records or reports respecting the Receivables or the conditions or operations,

of the Buyer under or as contemplated by this Agreement; and

          (g) as soon as possible and in any event with five Business Days after
the occurrence thereof, notification of: (i) any material changes in the
Seller's bank agreements, indentures or other material agreements governing
Indebtedness and/or (ii) any event which constitutes (or which, with the giving
of notice or the passage of time or both, would constitute) a default under any
such agreement or permits or (iii) any other event which permits (or which, with
the giving of notice or the passage of time, would permit) the holder of such
Indebtedness to accelerate the maturity thereof.

          SECTION 5.03. NEGATIVE COVENANTS OF THE SELLER. From the Closing Date
until the later of the Termination Date or the Collection Date, the Seller will
not, without the written consent of the Buyer:

          (a) SALES, LIENS, ETC. AGAINST RECEIVABLES AND TRANSFERRED ASSETS.
Except as otherwise provided herein, sell, assign (by operation of law or
otherwise) or otherwise dispose of, or create or suffer to exist, any Adverse
Claim upon or with respect to, any Receivable, Related Security or Collections,
or any related Contract, or upon or with respect to any Lock-Box Account to
which any Collections of any Receivable are sent, or assign any right to receive
income in respect thereof, or upon any other Transferred Asset, except that the
Seller shall have no responsibility for any Adverse Claim created by an Obligor
upon or with respect to any Equipment owned by such Obligor so long as such
Adverse Claim is subordinate to the security interest of the Seller in such
Equipment.

          (b) EXTENSION OR AMENDMENT OF RECEIVABLES. Extend, amend or otherwise
modify, the terms of any Receivable, or amend, modify or waive, any term or
condition of any Contract related thereto, except to the extent that the Seller,
in its capacity as Servicer, may make such amendments in accordance with the
Credit and Collection Policy or as otherwise permitted under ARTICLE VI hereof.

          (c) CHANGE IN BUSINESS OR CREDIT AND COLLECTION POLICY. Without the
prior written consent of the Collateral Agent, make any material change in the
character of its business or make any change in the Credit and Collection
Policy, which change would, in either case, impair the collectibility of any
Transferred Asset.

          (d) CHANGE IN PAYMENT INSTRUCTIONS TO OBLIGORS. (i) After giving the
payment instructions described in the first sentence of SECTION 4.01(k), make
any change in such instructions to Obligors regarding payments to be made to the

bank as a Lock-Box Bank from those listed in


                                       18

date of such addition, termination or change, (x) executed copies of Lock-Box
Agreements executed by each new Lock-Box Bank and (y) copies of all agreements
and documents signed by the Seller or the respective Lock-Box Bank with respect
to any new Lock-Box Account.

          (e) MERGER ETC. (i) Merge with or into or consolidate with or into or
convey, transfer, lease or otherwise dispose of (whether in one transaction or
in a series of transactions) all or substantially all of its assets (whether now
owned or hereafter acquired) or acquire all or substantially all of the assets
or capital stock or other ownership interest of, any Person, or permit any
Subsidiary of Seller to do so, except that (A) any Subsidiary of Seller may
merge or consolidate with or transfer assets to or acquire assets from any other
Subsidiary of Seller, (B) any Subsidiary of Seller may merge into or transfer
assets to the Seller or any other Person and (C) the Seller or any Subsidiary of
the Seller may acquire the capital stock or assets of any other Person, provided

no Event of Termination or event which, with the giving of notice or lapse of
time, or both, would constitute an Event of Termination, would exist, and in the
case of any such merger to which the Seller is a party, the Seller is the
surviving corporation.

          (f) CHANGE IN CORPORATE NAME. Make any change to its corporate name or
use any trade names, fictitious names, assumed names or "doing business as"
names other than those described in EXHIBIT I, unless the Seller has given to
the Buyer at least thirty (30) days' prior written notice thereof and, prior to
the effective date of any such name change or use, Seller delivers to the Buyer
such Financing Statements (Form UCC-1 and UCC-3) executed by Seller which the
Buyer may reasonably request to reflect such name change or use, together with
such other documents and instruments that the Buyer may request in connection
therewith.

          (g) ERISA MATTERS. (i) Engage or permit any ERISA Affiliate to engage
in any prohibited transaction for which an exemption is not available or has not
previously been obtained from the DOL; (ii) permit to exist any accumulated
funding deficiency, as defined in Section 302(a) of ERISA and Section 412(a) of

(iv) terminate any Benefit Plan so as to result in any liability; or (v) permit
to exist any occurrence of any reportable event described in Title IV of ERISA
which represents a material risk of a liability of the Seller or any ERISA
Affiliate under ERISA or the IRC; PROVIDED, HOWEVER, the Seller and its ERISA
Affiliates may take or allow such prohibited transactions, accumulated funding
deficiencies, payments, terminations and reportable events described in clauses
(i) through (iv) above so long as such events occurring within any fiscal year
of the Seller, in the aggregate, involve a payment of money by or an incurrence
of liability of the Seller or any ERISA Affiliate (collectively, "ERISA
Liabilities") in an amount which does not exceed $500,000.

                                       19

<PAGE>   24


          (h) TERMINATE OR REJECT CONTRACTS. Without limiting SECTION 5.03(b)
and except as otherwise expressly permitted pursuant to SECTION 2.05, terminate
or reject any Contract prior to the term of such Contract, whether such
rejection or early termination is made pursuant to an equitable cause, statute,
regulation, judicial proceeding or other applicable law (including, without
limitation, Section 365 of the Bankruptcy Code), unless prior to such
termination or rejection, the Seller shall have paid to the Buyer an amount
equal to the Termination Amount thereof.

          (i) ACCOUNTING TREATMENT. Prepare any financial statements or other
statements which shall account for the transactions contemplated by this
Agreement in any manner other than as the sale of, or a capital contribution of,
the Transferred Assets by the Seller to the Buyer (it being understood that
non-recognition of such transaction due to the application of consolidated
financial reporting principles under GAAP or the filing of tax returns on a
consolidated basis shall not constitute a violation of this covenant).

          (j) CERTIFICATE OF INCORPORATION. Cause the Buyer to amend its
Certificate of Incorporation or By-laws in any manner which would require the
consent of the Buyer's independent director or directors, without the Collateral
Agent's prior written consent.

          SECTION 5.04. FINANCIAL COVENANTS OF THE SELLER. (a) From the Closing
Date until the later of the Termination Date or the Collection Date, the Seller
will not suffer or permit:

               (i) CONSOLIDATED TANGIBLE NET WORTH. The Seller will not permit
               "Consolidated Tangible Net Worth" (as defined below) as of the
               end of any fiscal quarter to be less than the sum of (i)
               $35,000,000 PLUS (ii) on a cumulative basis, 75% of positive
               "Consolidated Net Income" (as defined below) for each fiscal
               quarter beginning with the fiscal quarter commencing on or after
               October 1, 1999 PLUS (iii) 100% of the proceeds of any sale by
               the Seller or any of its Subsidiaries of (A) equity securities
               issued by the Seller or any of its Subsidiaries, or (B) warrants
               or subscription rights for equity securities issued by the Seller
               or any of its Subsidiaries.

               (ii) Indebtedness of the Seller and its Consolidated Subsidiaries
               at the end of any fiscal quarter to exceed seven-hundred percent
               (700%) of Consolidated Tangible Net Worth at the end of such
               fiscal quarter. For purposes of this SECTION 5.04(a)(ii), the
               following shall be considered liabilities when calculating
               "Consolidated Tangible Net Worth" as used herein:

     (A) any Indebtedness of the Seller and/or its Consolidated Subsidiaries
     that (i) is unsecured and expressly subordinate to the repayment of the
     obligations evidenced by the Facility Documents and (ii) matures after the
     date that is less than five years from the date on which "Consolidated
     Tangible Net Worth" is calculated hereunder, excluding, without


                                       20

<PAGE>   25

     limitation, the unsecured and expressly subordinate Indebtedness with an
     aggregate principal amount equal to $20,000,000 in existence on March 31,
     2000, and

     (B) any preferred stock or other equity interests in the Seller and/or its
     Consolidated Subsidiaries that are subject to acceleration or other
     mandatory repayment conditions and that mature in fewer than five years
     from the date on which "Consolidated Tangible Net Worth" is calculated as
     required hereunder (the Indebtedness described in clause (A) and the
     preferred stock or other equity interests described in clause (B), taken
     together, the "Sub Debt");

PROVIDED, that, on any date of calculation, in the event the aggregate amount of
the Sub Debt exceeds an amount equal to 45% of the sum of (a) "Consolidated
Tangible Net Worth" PLUS (b) Sub Debt PLUS (c) any other Indebtedness, preferred
stock or equity interest that does not constitute Sub Debt, then the amount of
such excess shall constitute a liability for purposes of calculating
"Consolidated Tangible Net Worth" hereunder.

               (iii) The ratio of (A) "Consolidated EBIT" (as defined below) to
               (B) "Total Interest Expense" (as defined below), as of the end of
               any fiscal quarter, to be less than (1) 1.15 to 1.0 for the four
               fiscal quarter period then ending.

               (iv) the Seller to have a credit line less than $50,000,000 under
               the terms of at least one committed credit facility not insured
               by MBIA Insurance Corporation where such facility is extended to
               the Seller by a financial institution (with the understanding
               that such financial institution may not offer such facility
               through a commercial paper conduit) and the terms and conditions
               of such facility are in form and substance similar to the terms
               and conditions set forth in the Third Amended and Restated Credit
               Agreement, dated as of March 16, 1998 (as the same may be
               amended, restated, supplemented or otherwise modified from time
               to time, the "1998 Credit Agreement") among HPSC, Inc., American
               Commercial Finance Company, and BankBoston, N.A.

following meanings:

                                   ARTICLE VI
                          ADMINISTRATION AND COLLECTION

          SECTION 6.01. DESIGNATION OF SERVICER. Consistent with the Buyer's
ownership of the Transferred Assets, the Buyer shall have as against the Seller
the sole right to service, administer and collect the Receivables, to assign
such right and to delegate such right. The servicing, administering and
collection of the Receivables and the other Transferred Assets shall be
conducted by the Person (the "SERVICER") so designated by the Buyer from time to
time in accordance with this SECTION 6.01. Until the Collateral Agent gives
notice to the Seller of the designation of a new Servicer, the Seller is hereby
designated as, and hereby agrees to perform the duties and obligations of, the
Servicer pursuant to the terms hereof. The Buyer may, at any time upon ten
Business Days prior written notice, designate as Servicer any Person to succeed
the Seller on the condition any such Person so designated shall agree to perform
the duties and obligations of the Servicer pursuant to the terms hereof and
shall be acceptable to the Collateral


                                       22

<PAGE>   27


Agent; PROVIDED that the Buyer's right to so designate a successor Servicer at
any time is personal to the Buyer and may not be assigned to any other Person
(including the Collateral Agent). The Collateral Agent may at any time from and
after a Servicing Termination Event designate as Servicer any other Person to
succeed the Seller or any Successor Servicer, on the condition in each case that
any such Person so designated shall agree to perform the duties and obligations
of the Servicer pursuant to the terms hereof. The Servicer may, with the prior
written consent of the Buyer and the Collateral Agent, subcontract with any
other Person for servicing, administering or collecting the Transferred Assets,
provided that the Servicer shall remain liable for the performance of the duties
and obligations of the Servicer pursuant to the terms hereof. The Servicer shall
use reasonable care in performing its duties as Servicer hereunder and, without
limiting the foregoing, shall service the Transferred Assets in accordance with
the Credit and Collection Policy. The Servicer acknowledges that the Buyer has
(a) pursuant to the Credit Agreement, granted to the Collateral Agent, for the
benefit of Triple-A and the Surety, a security interest in Pledged Assets and
has assigned to the Collateral Agent all of its rights under this Agreement with
respect to such Pledged Assets, including its rights with respect to the
Servicer under this ARTICLE VI, as more fully described in SECTION 9.04
hereunder, and (b) pursuant to the Triple-A Purchase Agreement, sold to Triple-A
Purchased Assets which will be serviced pursuant to ARTICLE VI of the Triple-A
Purchase Agreement.

          SECTION 6.02. DUTIES OF THE SERVICER. (a) The Servicer shall take or
cause to be taken all such actions as may be necessary or advisable to collect
each Transferred Asset from time to time, all in accordance with applicable
laws, rules and regulations, with reasonable care and diligence, and in
accordance with the Credit and Collection Policy. The Buyer hereby appoints as
its agent the Servicer, from time to time designated pursuant to Section 6.01,
to enforce its respective rights and interests in and under the Receivables, the
Related Security, the related Contracts and the other Transferred Assets. The
Servicer will at all times apply the same standards and follow the same
procedures with respect to the decision to commence, and in prosecuting and
litigating with respect to Receivables as it applies and follows with respect to
accounts, chattel paper and instruments which are not Transferred Assets. In no
event shall the Servicer be entitled to make the Collateral Agent or the Buyer a
party to any litigation without the Buyer's and the Collateral Agent's express
prior written consent. The Servicer shall segregate and set aside for the
account of the Buyer all Collections of Transferred Assets in accordance with
SECTION 2.05 hereof, SECTION 6.06 of the Credit Agreement and SECTION 6.06 of
the Triple-A Purchase Agreement and shall cause all such Collections to be
remitted to a Lock-Box Account and/or deposited directly into the Collection
Account within one Business Day after identification thereof by the Servicer and
in any event within four Business Days after the Servicer's receipt thereof. The
Servicer shall promptly review all checks and other instruments returned to it
by the Lock-Box Bank on account of restrictive endorsements, improper payees,
incorrect amounts or for any other reason and shall not deposit any such checks
or instruments in its own accounts unless it is determined to the Buyer's
satisfaction that such amounts do not constitute Collections; any such checks or
instruments which are determined to be Collections shall be promptly remitted to
the Lock-Box Account or the Collection Account as provided above. Provided that
the Termination Date shall not have occurred, the Seller, while it is Servicer,
may, in accordance with the Credit and Collection Policy, (i) amend, modify or
waive


                                       23

<PAGE>   28


any term or condition of any Contract to reflect any Permitted Extension, (ii)
adjust the Outstanding Balance of any Transferred Asset to reflect the
reductions, adjustments or cancellations described in the first sentence of
SECTION 2.05 of the Purchase Agreement, (iii) so long as such prepayment would
not cause an Event of Termination under SECTION 7.01(m) hereof and subject to
the payment of the Termination Amount, consent to the prepayment or early
termination of a Contract, and (iv) amend, modify or waive any provision of a
Delinquent Receivable or Defaulted Receivable so as to maximize the
collectibility thereof. The Seller shall deliver to the Servicer, and the
Servicer shall hold in trust for the Seller and the Buyer in accordance with
their respective interests, all Records. Notwithstanding anything to the
contrary contained herein, following the occurrence of an Event of Termination,
the Collateral Agent shall have the absolute and unlimited right to direct the
Servicer (whether the Servicer is the Seller or otherwise) to commence or settle
any legal action to enforce collection of any Receivable or other Transferred
Asset or to foreclose upon or repossess any Related Security.

          (b) The Servicer shall as soon as practicable following receipt turn
over to the Seller the collections of any receivable which is not a Transferred
Asset less, in the event the Seller is not the Servicer, all reasonable and
appropriate out-of-pocket costs and expenses of such Servicer of servicing,
collecting and administering such receivable.

          (c) Notwithstanding anything to the contrary contained in this
Agreement, the Servicer, if the Collateral Agent or its designee, shall have no
obligation to collect, enforce or take any other action described in this
ARTICLE VI with respect to any receivable that is not a Transferred Asset other
than to deliver to the Seller the Collections and documents with respect to any
such receivable as described in the first two sentences of SECTION 6.02(b) and
to exercise the same degree of care with respect to Collections and documents in
its possession as it would exercise with respect to its own property.

          (d) The Servicer will, at the Servicer's cost and expense and as agent
in the name of and on behalf of the Buyer, but subject at any time to the right
of the Buyer to direct and control, endeavor to collect, as and when the same
becomes due, all amounts owing on each Receivable. In the event of default by an
Obligor under any Receivable, the Servicer shall have the power and authority,
on behalf of the Buyer, to take such action in respect of the enforcement and
collection of such Receivable as the Servicer, in the absence of contrary
instructions from the Buyer, may deem advisable. In any such suit for
enforcement or collection, the Servicer shall be entitled to sue thereon in its
own name or as agent for the Buyer, in either case, for the account of the
Buyer.

          (e) In the event the Servicer accepts in payment of any Receivable the
taking of repossession of the Equipment the sale or lease of which gave rise to
such Receivable, the Servicer agrees to use its reasonable efforts to resell or
re-lease such Equipment for the account of the Buyer and shall remit to the
Buyer the gross sale proceeds thereof or, to the extent such Equipment is
re-leased, shall deliver to the Buyer the chattel paper or other documents
evidencing the rights to payment arising from such re-lease, all of which
documents shall constitute Contracts and which rights to payment shall
constitute Receivables, and all of which

                                       24

<PAGE>   29


Contracts and Receivables shall constitute part of the Transferred Assets.
Neither the Buyer nor the Collateral Agent shall have any obligation to take any
action or commence any proceedings to realize upon any Receivable or to enforce
any of its rights or remedies with respect thereto. Any moneys collected by the
Servicer pursuant to this SUBSECTION 6.02(e) shall be segregated by the
Servicer, held in trust by the Servicer for the Buyer and shall be remitted to a
Lock-Box Account or to the Collection Account within one Business Day after
identification thereof by the Servicer and in any event within four Business
Days after the Servicer's receipt thereof.

          (f) The Servicer shall maintain all books of account and other records
pertaining to the Receivables and the other Transferred Assets in such form as
will enable the Buyer or its designees to determine at any time the status
thereof. The Servicer will permit the Buyer, the Collateral Agent and any Person
designated by the Buyer or the Collateral Agent, during regular business hours,
to inspect, audit, check and make abstracts from all books, accounts, records,
or other papers pertaining to such Transferred Assets. From time to time, at the
request of the Buyer or the Collateral Agent, the Servicer, at its own expense,
will (i) deliver to the Buyer and the Collateral Agent and any Person designated
by the Buyer or the Collateral Agent any records and invoices pertaining to the
Transferred Assets and evidence thereof as the Buyer, the Collateral Agent or
such designee may deem necessary to enable it to enforce its rights thereunder
and (ii) mark each computer record relating to, and each invoice or other
evidence of, the Transferred Assets (whether or not such computer record or
other item is the property of the Buyer) as the Buyer or Collateral Agent may
direct to reflect the interests of the Buyer and the Collateral Agent in such
Transferred Assets. The Servicer will either (i) segregate, from all the
documents relating to other receivables then owned or being serviced by the
Servicer, all documents relating to the Transferred Assets or (ii) mark all such
documents relating to the Transferred Assets so as to make such documents
readily identifiable as property of the Buyer and with such legend as shall be
specified by the Collateral Agent, and will, in either such event, hold all such
documents in trust for the Buyer and safely keep such documents in filing
cabinets or other suitable containers marked to show the Buyer's interest.

          SECTION 6.03. Rights of the Buyer. At any time:

          (a) The Buyer may notify the Obligors of the Receivables, or any of
them, of the Buyer's ownership interest in Transferred Assets and direct such
Obligors, or any of them, that payment of all amounts payable under any
Receivable be made directly to the Buyer or its designee (including, without
limitation, the Collateral Agent).

          (b) The Seller shall, at the Collateral Agent's or Buyer's request and
at the Seller's expense, give notice of the Buyer's interest in the Transferred
Assets to each Obligor (in substantially the form of the Notice of Assignment)
and direct that payments be made directly to the Buyer or its designee
(including, without limitation, the Collateral Agent).

          (c) The Seller shall, at the Buyer's request, assemble all Records
which the Buyer reasonably believes are necessary or appropriate for the
administration and enforcement of the


                                       25

<PAGE>   30


Transferred Assets, and shall make the same available to the Buyer at a place
selected by the Buyer or its designee.

          (d) The Seller hereby authorizes the Buyer and the Collateral Agent to
take any and all steps in the Seller's name and on behalf of the Seller
necessary or desirable, in the determination of the Buyer and/or the Collateral
Agent, to collect all amounts due under any and all Transferred Assets or
related Receivables, including, without limitation, endorsing the Seller's name
on checks and other instruments representing Collections and enforcing such
Receivables and the related Contracts.

          SECTION 6.04. FURTHER ACTION EVIDENCING TRANSFERS. The Seller agrees
that from time to time, at its expense, it will promptly execute and deliver all
further instruments and documents, and take all further action that the Buyer
may reasonably request in order to perfect, protect or more fully evidence the
Buyer's interest in the Transferred Assets, or to enable the Buyer to exercise
or enforce any of its rights hereunder or under any related document. Without
limiting the generality of the foregoing, the Seller will mark its master data
processing records evidencing such Transferred Assets with a legend, acceptable
to the Buyer, evidencing that the Buyer has acquired an ownership interest
therein as provided in this Agreement and, upon the request of the Buyer, will
execute and file such financing or continuation statements, or amendments
thereto or assignments thereof, and such other instruments or notices, as may be
necessary or appropriate or as the Buyer may reasonably request. The Seller
hereby authorizes the Buyer to file one or more financing or continuation
statements, and amendments thereto and assignments thereof, relative to all or
any of the Transferred Assets now existing or hereafter arising without the
signature of the Seller where permitted by law. A carbon, photographic or other
reproduction of this Agreement or any financing statement covering the
Transferred Assets, or any part thereof, shall be sufficient as a financing
statement. If the Seller fails to perform any of its agreements or obligations
under this Agreement, the Buyer may (but shall not be required to) itself
perform, or cause performance of, such agreement or obligation, and the expenses
of the Buyer incurred in connection therewith shall be payable by the Seller
upon the Buyer's demand therefor; PROVIDED, HOWEVER, prior to taking any such
action, the Buyer shall give notice of such intention to the Seller and provide
the Seller with a reasonable opportunity to take such action itself.

          SECTION 6.05. RESPONSIBILITIES OF THE SELLER. Anything herein to the
contrary notwithstanding, the Seller shall (i) perform all of its obligations
under the Contracts to the same extent as if such Contracts had not been
transferred to the Buyer under the Purchase Agreement and the exercise by the
Buyer or its assigns of their respective rights hereunder shall not relieve
Seller from such obligations and (ii) pay when due any taxes, including without
limitation, sales, excise and personal property taxes payable in connection with
the Transferred Assets, unless the Seller is contesting the payment of such
taxes in good faith and by appropriate proceedings and with respect to which no
Adverse Claim has been asserted or filed.

          SECTION 6.06. ADMINISTRATION OF COLLECTIONS BY SERVICER. (a) The
Servicer shall identify on a timely basis all collections which are on account
of the Transferred Assets.


                                       26
<PAGE>   31


including all deposits to Lock Box Accounts. On each Business Day, all
Collections received in the Lock Box Accounts for the prior Business Day (and
such Business Day, if practicable) shall be transferred to the Collection
Account. If the Servicer receives any cash or checks, drafts, wire transfers or
other instruments for the payment of money on account or otherwise in respect of
the Transferred Assets, the Servicer shall segregate such cash and other items,
hold such cash and other items in trust for the benefit of the Buyer and the
Collateral Agent and shall cause such cash and other items (properly endorsed,
where required, so that such items may be collected by the Buyer) to be
deposited in a Lock Box Account or directly in the Collection Account
immediately after the date any such cash or other item shall have been
identified as being on account of a Transferred Asset.

          SECTION 6.07. APPLICATION OF COLLECTIONS. All Collections on account
of the Receivables of each Obligor shall be applied in the order of maturity
thereof unless specifically identified otherwise in writing by such Obligor or
directed by a court of competent jurisdiction. Any payment by an Obligor in
respect of any indebtedness or other obligations owed by such Obligor to the
Seller or the Servicer shall, except as otherwise specified by such Obligor or
otherwise required by law, be applied as a Collection of a Receivable of such
Obligor (in the order of the age by invoice date of such Receivables, starting
with the oldest such Receivable) to the extent of any amounts then due and
payable thereunder before being applied to any other indebtedness of such
Obligor to the Seller or the Servicer. The Servicer shall not influence or
instruct any Obligor who is indebted to the Seller in respect of any
indebtedness not included in the Transferred Assets to direct that its
remittances be applied to any such indebtedness prior to being applied to the
Transferred Assets.

          SECTION 6.08. SERVICING FEE. On each Settlement Date, as full
compensation for its servicing activities hereunder, the Servicer shall be
entitled to receive a fee (the "SERVICING FEE") in an amount equal to 1.0% TIMES
the Outstanding Balance of the Receivables as of the last day of the prior
calendar month TIMES a fraction, the numerator of which is the number of actual
days elapsed in such calendar month and the denominator of which equals 360.
Notwithstanding the foregoing, to the extent that Advances under the Liquidity
Agreement are used to fund or maintain Borrowings or Purchases, then the
Servicing Fee shall be .75% TIMES the Outstanding Balance of the Receivables as
of the last day of the prior calendar month TIMES a fraction, the numerator of
which is the number of actual days elapsed in such calendar month and the
denominator of which equals 360. In the event that the Buyer (or the Collateral
Agent) appoints a successor Servicer, the Servicing Fee may be adjusted as
required by such successor Servicer and as agreed to by the Buyer and the
Collateral Agent.

          SECTION 6.09. RESIGNATION; SUCCESSOR SERVICER. (a) The obligation of
the Servicer to service the Receivables is personal to the Servicer and the
parties recognize that another Person may not be qualified to perform such
obligations. Accordingly, the Servicer's obligation to service the Transferred
Assets hereunder shall be specifically enforceable and shall be absolute and
unconditional in all circumstances, including, without limitation, after the
occurrence and during the continuation of any Event of Termination or Servicing
Termination


                                       27

<PAGE>   32


Event hereunder; PROVIDED, HOWEVER, that a Successor Servicer may be appointed
pursuant to this SECTION 6.09.

          (b) Notwithstanding the foregoing, the Servicer may resign from the
obligations and duties hereby imposed on it as Servicer upon determination that
(i) the performance of its duties hereunder is no longer permissible under any
applicable law and (ii) there is no reasonable action which the Servicer could
take to make the performance of its duties hereunder permissible under any such
applicable law. Any determination permitting the resignation of the Servicer
shall be evidenced as to clause (i) above by an opinion of counsel to such
effect delivered to the Buyer and the Collateral Agent. Except to the extent
inconsistent with any such applicable law, no such resignation shall become
effective until a Successor Servicer shall have assumed the responsibilities and
obligations of the Servicer in accordance with the remaining provisions of this
SECTION 6.09.

          (c) The Collateral Agent shall, as promptly as possible after the
Servicer has given notice pursuant to SECTION 6.09(b) above or at any time after
the Buyer's or the Collateral Agent's designation of a successor Servicer
pursuant to SECTION 6.01, appoint a successor servicer (the "SUCCESSOR
SERVICER") and such Successor Servicer shall accept its appointment by a written
assumption in a form acceptable to the Collateral Agent. Upon its appointment,
the Successor Servicer shall be the successor in all respects to the Servicer
with respect to servicing functions under this Agreement and the Credit
Agreement shall be subject to all the responsibilities, duties and liabilities
relating thereto placed on the Servicer by the terms and provisions hereof and
thereof, and all references in this Agreement or any other Facility Documents to
the Servicer shall be deemed to refer to the Successor Servicer. The Servicer
agrees to cooperate with the Successor Servicer in effecting the transfer of its
responsibilities, duties, liabilities and rights hereunder, including, without
limitation, the execution and delivery of assignments of financing statements,
the transfer to the Successor Servicer of all cash amounts held by the Servicer
or thereafter received with respect to the Transferred Assets, the transfer of
electronic records relating to the Transferred Assets in such form as the
Successor Servicer may reasonably request and the transfer of all related
Records, correspondence and other documents relating to the Transferred Assets.

                              EVENTS OF TERMINATION

          SECTION 7.01. EVENTS OF TERMINATION. If any of the following events
("Events of Termination") shall occur:

          (a) (i) The Servicer (if the Seller or any Affiliate of the Seller)
shall fail to perform or observe any term, covenant or agreement hereunder
(other than as referred to in clause (ii) of this SECTION 7.01(a)) and such
failure shall remain unremedied for three Business Days after written notice
from the Buyer or (ii) either the Servicer (if the Seller or any Affiliate of
the Seller) or the Seller shall fail to make any payment or deposit to be made
by it hereunder when due and with respect to such payments which do not relate
to the remittance of Collections,

                                       28

<PAGE>   33

such failure shall remain unremedied for three Business Days after written
notice from the Buyer; or

          (b) The Seller shall fail to perform or observe any term, covenant or
agreement contained in ARTICLE VI and any such failure shall remain unremedied
for five Business Days after written notice from the Buyer; or

          (c) Any representation or warranty made or deemed to be made by the
Seller (or any of its officers) under or in connection with this Agreement, any
Settlement Report or other information or report delivered pursuant hereto shall
prove to have been false or incorrect in any material respect when made;
PROVIDED, HOWEVER, that (i) to the extent any breach of any such representation
or warranty may be cured within ten Business Days, the Seller shall have ten
Business Days after learning of such breach to make such representation and
warranty true and correct and (ii) if any such false or incorrect representation
or warranty has given rise to a deemed collection as provided under SECTION
2.05, then, upon the Seller's payment of such deemed Collection at the time and
in the manner required under this Agreement, the breach of such representation
or warranty shall not give rise to an Event of Termination under this subsection
(c); or

          (d) The Seller shall fail to perform or observe any other term,
covenant or agreement contained in this Agreement on its part to be performed or
observed and any such failure shall remain unremedied for ten Business Days
after written notice from the Buyer (it being understood that, if any such
failure gives rise to a deemed Collection as provided under SECTION 2.05, then
the payment of such deemed Collection at the time and in the manner required
under this Agreement shall be deemed a remedy of such failure); or

          (e) The Seller shall fail to pay any principal of or premium or
interest on any Indebtedness when the same becomes due and payable (whether by
scheduled maturity, required prepayment, acceleration, demand or otherwise) and
such failure shall continue after the applicable grace period, if any, specified
in the agreement or instrument relating to such Indebtedness; or any other
default under any agreement or instrument relating to any such Indebtedness of
the Seller or any other event, shall occur and shall continue after the
applicable grace period, if any, specified in such agreement or instrument if
the effect of such default or event is to accelerate, or to permit the
acceleration of, the maturity of such Indebtedness; or any such Indebtedness
shall be declared to be due and payable or required to be prepaid (other than by
a regularly scheduled required prepayment) prior to the stated maturity thereof;
or

          (f) Any Purchase or acquisition by the Buyer of Transferred Assets
shall for any reason, except to the extent permitted by the terms hereof, cease
to create a valid and perfected first priority interest in each Receivable, the
Related Security and the Equipment and Collections with respect thereto;
provided, HOWEVER, if any such failure results in a deemed Collection under
SECTION 2.05 hereof and the Seller satisfies in full its payment obligations
under such section, then such failure shall not give rise to an Event of
Termination under this subsection (f); or

                                       29

<PAGE>   34


          (g) (i) An Insolvency Event shall occur with respect to the Seller or
the Buyer or (ii) the Seller or the Buyer shall take any corporate action to
authorize the filing of any Insolvency Proceeding; or

          (h) There shall have been any material adverse change in the financial
condition or operations of the Seller since December 31, 1999 (except as
disclosed in the Interim Financials described in SECTION 4.01(e)), or there

          (j) As of the last day of any month, the "Default Ratio" for the
aggregate of Receivables subject to the terms of the Credit Agreement and
Receivables subject to the terms of the Triple-A Purchase Agreement shall be
greater than 3.5%; or

          (k) As of the last day of any month, the "Delinquency Ratio" for the
aggregate of Receivables subject to the terms of the Credit Agreement and
Receivables subject to the terms of the Triple-A Purchase Agreement shall be
greater than 3.5%; or

          Any "Wind-Down Event" shall occur under the Credit Agreement or any
"Wind-Down Event" shall occur under the Triple-A Purchase Agreement; or

then, and in any such event, the Buyer may by notice to the Seller declare the
Termination Date to have occurred, EXCEPT that, in the case of any event
described in clause (i) of subsection (g) above, the Termination Date shall be
deemed to have occurred automatically upon the occurrence of such event. Upon
any such declaration or automatic occurrence, the Buyer shall have, in addition
to all other rights and remedies under this Agreement or otherwise, all other
rights and remedies provided under the UCC of the applicable jurisdiction and
other applicable laws, which rights shall be cumulative.

                                  ARTICLE VIII
                                 INDEMNIFICATION

other rights which the Buyer may have hereunder or under applicable law, the
Seller hereby agrees to indemnify the Buyer and its permitted successors and

               free and clear of any Permitted Encumbrance except in favor of
               the Buyer or its assignees) whether existing at the time of the
               Purchase of such Receivable or at any time thereafter;

               (v) the failure to file, or any delay in filing (other than

               under the UCC of any applicable jurisdiction or other applicable
               laws against the Seller with respect to any Contract or

               in bankruptcy of the Obligor) of the Obligor to the payment of

               (x) the termination, rejection or non-assumption by the Seller of
               any Contract prior to the original term of such Contract, whether
               such rejection, early termination or non-assumption is made
               pursuant to an equitable cause, statute, regulation, judicial
               proceeding or other applicable laws (including, without
               limitation, Section 365 of the Bankruptcy Code);

          SECTION 9.01. AMENDMENTS, ETC. No amendment to or waiver of any
provision of this Agreement nor consent to any departure by the Seller, shall in
any event be effective unless the same shall be in writing and signed by (i) the
Seller and the Buyer (with respect to an amendment) or (ii) the Buyer (with
respect to a waiver or consent by it) or the Seller (with respect to a waiver or
consent by it), as the case may be, and then such waiver or consent shall be
effective only in the specific instance and for the specific purpose for which
given. This Agreement contains a final and complete integration of all prior
expressions by the parties hereto with respect to the subject matter hereof and
shall constitute the entire agreement (together with


                                       32
<PAGE>   37


the exhibits hereto) among the parties hereto with respect to the subject matter
hereof, superseding all prior oral or written understandings.

          SECTION 9.02. NOTICES, ETC. All notices and other communications
provided for hereunder shall, unless otherwise stated herein, be in writing
(including telex communication and communication by facsimile copy) and mailed,
telexed, transmitted or delivered, as to each party hereto, at its address set
forth under its name on the signature pages hereof or at such other address as
shall be designated by such party in a written notice to the other parties
hereto. All such notices and communications shall be effective, upon receipt, or
in the case of delivery by mail, five days after being deposited in the mails,
or, in the case of notice by telex, when telexed against receipt of answer back,
or in the case of notice by facsimile copy, when verbal communication of receipt
is obtained, in each case addressed as aforesaid, except that notices and
communications pursuant to Article II shall not be effective until received.

          SECTION 9.03. NO WAIVER; REMEDIES. No failure on the part of the Buyer
to exercise, and no delay in exercising, any right hereunder shall operate as a
waiver thereof; nor shall any single or partial exercise of any right hereunder
preclude any other or further exercise thereof or the exercise of any other
right. The remedies herein provided are cumulative and not exclusive of any
remedies provided by law.

          SECTION 9.04. BINDING EFFECT; ASSIGNABILITY. This Agreement shall be
binding upon and inure to the benefit of the Seller, the Buyer and their
respective successors and permitted assigns (which successors of the Seller
shall include a trustee in bankruptcy). The Seller may not assign any of its
rights and obligations hereunder or any interest herein without the prior
written consent of the Buyer and the Collateral Agent. The Buyer may assign at
any time its rights and obligations hereunder and interests herein to any other
Person without the consent of the Seller. Without limiting the foregoing, the
Seller acknowledges that the Buyer shall (i) assign to the Collateral Agent, for
the benefit of Triple-A and the Surety, as collateral security for its
obligations under the Credit Agreement, all of its rights, remedies, powers and
privileges hereunder with respect to Pledged Assets pledged to the Collateral
Agent thereunder and (ii) sell to Triple-A all of its right, remedies, powers
and privileges hereunder with respect to Purchased Assets (as defined in the
Triple-A Purchase Agreement), and that Triple-A and/or the Collateral Agent may
further assign such rights, remedies, powers and privileges to the extent
permitted in the Credit Agreement and the Triple-A Purchase Agreement. The
Seller agrees that the Collateral Agent, as the assignee of the Buyer, or
Triple-A, as appropriate, shall, subject to the terms of the Credit Agreement
and the Triple-A Purchase Agreement, have the right to enforce this Agreement
and to exercise directly all of the Buyer's rights and remedies under this
Agreement (including, without limitation, the rights and remedies under SECTIONS
6.01, 6.02, 6.03, 6.04 and 8.01) and the Seller agrees to cooperate fully with
the Collateral Agent and/or Triple-A in the exercise of such rights and
remedies. Without limiting the foregoing, the Seller hereby acknowledges that
the Buyer and Triple-A have agreed pursuant to the Credit Agreement, the
Triple-A Purchase Agreement and certain related agreements that, subject to the
restrictions set forth therein, the Collateral Agent and certain parties
providing credit enhancements and/or liquidity for Triple-A in connection with
the Credit Agreement and the Triple-A Purchase


                                       33
<PAGE>   38


Agreement shall be entitled to exercise the Buyer's rights under this Agreement.
The Seller hereby consents to the foregoing and agrees to cooperate with any
such Person electing to exercise the Buyer's rights under this Agreement. This
Agreement shall create and constitute the continuing obligations of the parties
hereto in accordance with its terms, and shall remain in full force and effect
until such time, after the Termination Date, as the Collection Date shall occur;
PROVIDED, HOWEVER, that the rights and remedies with respect to any breach of
any representation and warranty made by the Seller pursuant to ARTICLE IV and
the indemnification and payment provisions of ARTICLE VIII and ARTICLE X shall
be continuing and shall survive any termination of this Agreement.

          SECTION 9.05. GOVERNING LAW; WAIVER OF JURY TRIAL. THIS AGREEMENT
SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF
NEW YORK, EXCEPT TO THE EXTENT THAT THE VALIDITY OR PERFECTION OF THE INTERESTS
OF THE BUYER IN THE TRANSFERRED ASSETS OR REMEDIES HEREUNDER OR THEREUNDER, IN
RESPECT THEREOF, ARE GOVERNED BY THE LAWS OF A JURISDICTION OTHER THAN THE STATE
OF NEW YORK. THE SELLER HEREBY AGREES TO THE JURISDICTION OF ANY FEDERAL COURT
LOCATED WITHIN THE STATE OF NEW YORK, AND WAIVES PERSONAL SERVICE OF ANY AND ALL
PROCESS UPON IT AND CONSENTS THAT ALL SUCH SERVICE OF PROCESS BE MADE BY
REGISTERED MAIL DIRECTED TO THE SELLER AT THE ADDRESS SET FORTH ON THE SIGNATURE
PAGE HEREOF AND SERVICE SO MADE SHALL BE DEEMED TO BE COMPLETED FIVE (5) DAYS
AFTER THE SAME SHALL HAVE BEEN DEPOSITED IN THE U.S. MAILS, POSTAGE PREPAID, OR,
AT THE BUYER'S OPTION, BY SERVICE UPON CT CORPORATION SYSTEM, 1633 BROADWAY, NEW
YORK, NEW YORK 10019, WHICH THE SELLER HEREBY IRREVOCABLY APPOINTS AS ITS AGENT
FOR THE PURPOSE OF ACCEPTING SERVICE OF PROCESS. THE SELLER HEREBY WAIVES ANY
RIGHT TO HAVE A JURY PARTICIPATE IN RESOLVING ANY DISPUTE, WHETHER SOUNDING IN
CONTRACT, TORT, OR OTHERWISE BETWEEN THE SELLER AND THE BUYER ARISING OUT OF,
CONNECTED WITH, RELATED TO, OR INCIDENTAL TO THE RELATIONSHIP BETWEEN THEM IN
CONNECTION WITH THIS AGREEMENT. INSTEAD, ANY DISPUTE RESOLVED IN COURT WILL BE
RESOLVED IN A BENCH TRIAL WITHOUT A JURY. WITH RESPECT TO THE FOREGOING CONSENT
TO JURISDICTION, THE SELLER HEREBY WAIVES ANY OBJECTION BASED ON FORUM NON
CONVENIENS, AND ANY OBJECTION TO VENUE OF ANY ACTION INSTITUTED HEREUNDER AND
CONSENTS TO THE GRANTING OF SUCH LEGAL OR EQUITABLE RELIEF AS IS DEEMED
APPROPRIATE BY THE COURT. NOTHING IN THIS SECTION 9.05 SHALL AFFECT THE RIGHT OF
THE BUYER TO SERVE LEGAL PROCESS IN ANY OTHER MANNER PERMITTED BY LAW OR AFFECT
THE RIGHT OF THE BUYER TO BRING ANY ACTION OR PROCEEDING AGAINST THE SELLER OR
ITS PROPERTY IN THE COURTS OF ANY OTHER JURISDICTION.

          SECTION 9.06. COSTS, EXPENSES AND TAXES. (a) In addition to the rights
of indemnification under ARTICLE VIII hereof, the Seller agrees to pay on demand
all reasonable

                                       34

<PAGE>   39


costs and expenses in connection with the preparation, execution, delivery and
administration (including periodic auditing and any requested amendments,
waivers or consents) of this Agreement and the other documents to be delivered
hereunder, including, without limitation, the reasonable fees and out-of-pocket
expenses of counsel for the Buyer (and the Collateral Agent) with respect
thereto and with respect to advising the Buyer (and the Collateral Agent) as to
its rights and remedies under this Agreement, and the other agreements executed
pursuant hereto and all costs and expenses, if any (including reasonable counsel
fees and expenses), in connection with the enforcement of this Agreement and the
other agreements and documents to be delivered hereunder.

          (b) In addition, the Seller shall pay any and all stamp, sales, excise
and other taxes and fees payable or determined to be payable in connection with
the execution, delivery, filing and recording of this Agreement or the other
agreements and documents to be delivered hereunder, and agrees to indemnify the
Buyer and its assignees against any liabilities with respect to or resulting
from any delay in paying or omission to pay such taxes and fees.

          SECTION 9.07. EXECUTION IN COUNTERPARTS; SEVERABILITY. This Agreement
may be executed in any number of counterparts and by different parties hereto in
separate counterparts, each of which when so executed shall be deemed to be an
original and all of which when taken together shall constitute one and the same
agreement. In case any provision in or obligation under this Agreement or the
Certificate shall be invalid, illegal or unenforceable in any jurisdiction, the
validity, legality and enforceability of the remaining provisions or
obligations, or of such provision or obligation in any other jurisdiction, shall
not in any way be affected or impaired thereby.

          SECTION 9.08. REFERENCE TO AND EFFECT ON PRIOR PCA. Each of the
parties hereto ratifies the sales, conveyances, payments, representations,
warranties, covenants and indemnities made by such party in the Prior PCA and
agrees that such agreement is, as of the date hereof, in full force and effect.
From and after the effectiveness of the initial Receivables Purchase under this
Agreement in accordance with Section 3.01, (i) the terms and provisions of this
Agreement shall amend and supersede the terms and provisions of the Prior PCA in
its entirety, (ii) the continuing rights, remedies and obligations of the
parties with respect to any Receivables acquired under the Prior PCA shall be
governed by the terms and provisions of this Agreement to the same extent as if
such Receivables had been conveyed under this Agreement, and (iii) all
references in any other Facility Documents to the Prior PCA or Appendix A
thereto shall mean and be a reference to this Agreement and Appendix A hereto.
It is expressly understood and agreed that the execution and delivery of this
Agreement is not intended to be, and shall not be construed as, a novation of
the Prior PCA nor of any liens granted or indebtedness incurred thereunder.

                              AMENDED AND RESTATED

                      LEASE RECEIVABLES PURCHASE AGREEMENT

     THIS AMENDED AND RESTATED LEASE RECEIVABLES PURCHASE AGREEMENT, dated as of
March 31, 2000 (as the same may be amended, restated, supplemented or otherwise
modified from time to time, the "TRIPLE-A PURCHASE AGREEMENT"), is entered into
by and among HPSC BRAVO FUNDING CORP., a Delaware corporation, as Seller (the
"SELLER"), HPSC, INC., a Delaware corporation, as Servicer (the "SERVICER"),
TRIPLE-A ONE FUNDING CORPORATION, a Delaware corporation ("TRIPLE-A") and
CAPITAL MARKETS ASSURANCE CORPORATION, a New York stock insurance company
("CAPMAC"), as Collateral Agent and as Administrative Agent (in such capacities,
the "COLLATERAL AGENT" or the "ADMINISTRATIVE AGENT").

                              W I T N E S S E T H:

     WHEREAS, the Seller, the Servicer, Triple-A, and CapMAC are parties to that
certain Lease Receivables Purchase Agreement, dated as of October 18, 1996 (as
amended, the "Prior LRPA"); and

     WHEREAS, the Seller, the Servicer, Triple-A, and CapMAC desire to amend and
restate the Prior LRPA in certain respects;

     NOW, THEREFORE, the Seller, the Servicer, Triple-A, and CapMAC have agreed
to amend and restate the Prior LRPA in its entirety as follows:

                                    ARTICLE I

                                   DEFINITIONS

     SECTION 1.01 CERTAIN DEFINITIONS. As used in this Triple-A Purchase
Agreement or any certificate or other document made or delivered pursuant hereto
or thereto, the capitalized terms used herein and therein shall, unless
otherwise defined herein or therein, have the meanings assigned to them in the
Definitions List attached hereto as Appendix A, the terms of which are
incorporated herein by reference (the "DEFINITIONS LIST"). Any reference in the
Facility Documents to a note, instrument, or other agreement substantially in
the form of Exhibit K-1, K-2, K-3, or K-4 to the Purchase Agreement, as
applicable, shall mean and be a reference to a note, instrument or other
agreement in substantially one of the forms included in such Exhibit.

     SECTION 1.02. ACCOUNTING TERMS. As used herein and in any certificate or
other document made or delivered pursuant hereto and thereto, accounting terms
not defined in the Definitions List and accounting terms partly defined in the
Definitions List to the extent not defined, shall have the respective meanings
given to them under GAAP.

<PAGE>   6


     SECTION 1.03. OTHER TERMS. (a) All other undefined terms contained in this
Triple-A Purchase Agreement shall, unless the context indicates otherwise, have
the meanings provided for by the UCC to the extent the same are used or defined
therein.

     (b)  The words "hereof", "herein" and "hereunder" and words of similar
import when used in this Triple-A Purchase Agreement shall refer to this
Triple-A Purchase Agreement as a whole and not to any particular provision of
this Triple-A Purchase Agreement, and Section, subsection, Schedule and Exhibit
references are to this Triple-A Purchase Agreement unless otherwise specified.

     (c)  Capitalized terms used herein shall be equally applicable to both the
singular and plural forms of such terms.

     SECTION 1.04. COMPUTATION OF TIME PERIODS. In this Triple-A Purchase
Agreement, in the computation of periods of time from a specified date to a
later specified date, the word "from" shall mean "from and including" and the
words "to" and "until" shall each mean "to but excluding."

                                   ARTICLE II

                        AMOUNT AND TERMS OF THE PURCHASES

     SECTION 2.01. RECEIVABLES PURCHASE FACILITY. Triple-A shall subject to the
terms and conditions hereinafter set forth, make purchases of Receivables
("RECEIVABLES PURCHASES") from time to time on any Settlement Date (except that
the initial Receivables Purchase may be on a date other than a Settlement Date)
during the period from the date the conditions precedent in SECTION 3.01 are
satisfied to the Termination Date. Notwithstanding the foregoing, if, at any
time, two or more of the individuals who held the positions of Chief Executive
Officer, Chief Financial Officer and President of the Servicer as of April 30,
1998 no longer remain actively involved in the day-to-day management of the
Servicer, then Triple-A is no longer required to, but may, in its sole
discretion, make Receivables Purchases. Each Receivables Purchase shall
constitute an assignment and sale by the Seller, and a purchase and acquisition
by Triple-A of Purchased Assets, including, without limitation, Designated
Receivables identified as Eligible Receivables by the Seller, and Related
Security and Collections with respect thereto. Under no circumstances shall
Triple-A make any Receivables Purchase if, after giving effect to such
Receivables Purchase, the aggregate outstanding Capital hereunder would exceed
the least of (i) the Facility Limit, (ii) the Capital Limit, or (iii) the sum,
on such Receivables Purchase Date, of (a) the net proceeds from the sale of
Commercial Paper PLUS (b) the proceeds of Advances. The Capital Limit in effect
on any date shall be determined by reference to the most recent Settlement
Report delivered by the Seller to Triple-A in accordance with SECTION 5.02(f)
hereof (i) as adjusted on the most recent Settlement Date to reflect additional
Eligible Receivables sold on such Settlement Date since the delivery of such
Settlement Report and (ii) as adjusted on any other date of determination to
eliminate from the Discounted Eligible Receivables Balance any Receivables which
were Eligible Receivables as of the dates reflected in the Settlement Report but
which no longer satisfy the criteria for Eligible Receivables. It is the
intention of the parties hereto that each Receivables Purchase to be made


                                       2

<PAGE>   7

hereunder shall constitute either (i) a "sale of accounts or chattel paper", as
such term is used in Article 9 of the UCC, or (ii) a sale of "instruments", as
such term is used in Article 9 of the UCC. If at any time a court characterizes
the transactions hereunder as loans by Triple-A to the Seller, then the Seller
hereby pledges, grants a security interest in and assigns to the Collateral
Agent, for the benefit of Triple-A, all of the right and title to and interest
in the Purchased Assets, including the Purchased Receivables and the Related
Security, Collections and Equipment related thereto, as security for such loans
and for the payment and performance of all obligations of the Seller hereunder.

     SECTION 2.02. MAKING PURCHASES FROM THE SELLER.

     (a)  SALE NOTICE. Whenever the Seller wishes to sell Receivables hereunder,
it shall deliver to Triple-A a notice ("SALE NOTICE") in substantially the form
of EXHIBIT A hereto no later than 10:00 A.M. (New York City time) on the
Business Day immediately prior to the proposed Receivables Purchase Date;
PROVIDED that, in the case of any Capital funded as part of a Receivables
Purchase with respect to which Yield is to be calculated at the Eurodollar Rate,
such Sale Notice must be given not later than 10:00 A.M. (New York City time) at
least three (3) Business Days prior to the proposed Receivables Purchase Date.
Each Sale Notice shall be by telephone, telex, telecopy, cable or other
facsimile transmission (in the case of any such Sale Notice by telephone,
confirmed immediately in writing) and shall specify therein the (i) aggregate
initial Capital to be funded in connection with such Receivables Purchase, (ii)
the date of such Receivables Purchase and (iii) the duration of the initial
Fixed Period(s) for such Capital. In addition to the foregoing, the Seller shall
indicate which Receivables subject to such Sale Notice are Designated
Receivables and which Receivables subject to such Sale Notice are Non-Designated
Receivables.

     (b)  AMOUNT OF PURCHASED ASSETS; DEFERRED PURCHASE PRICE. The consideration
for each Receivables Purchase shall consist of the Capital funded under this
Agreement and the obligation of the Purchaser to remit to the Seller the
Deferred Purchase Price. The amount of the Deferred Purchase Price shall be
initially computed as of the opening of business of the Collection Agent on the
date of the initial Receivables Purchase hereunder. Thereafter until the
Termination Date, the amount of the Deferred Purchase Price shall be
automatically recomputed as of the close of business of the Collection Agent on
each day on which the aggregate Capital hereunder is increased or decreased or
on which any funds are remitted to the Seller in satisfaction thereof under
clause (v) of SECTION 6.11(b). From and after the Termination Date until the
Collection Date, the Deferred Purchase Price shall be automatically recomputed
on each Business Day to reflect any reductions in the amount hereof on account
of accrued Yield, Carrying Costs, or other amounts owed by (or paid on behalf
of) the Seller under this Agreement. The Purchased Assets shall become zero at
such time as Triple-A shall have recovered the aggregate outstanding Capital and
shall have received all other amounts payable to Triple-A pursuant to this
Triple-A Purchase Agreement and the Seller has received payment of the Deferred
Purchase Price. The Purchased Assets and the Deferred Purchase Price shall each
remain constant from the time as of which any such computation or recomputation
is made until the time as of which the next such recomputation, if any, shall be
made. Triple-A shall, in consideration of the sale of the Purchased Assets, from
and after the Collection Date, remit to the


                                       3

<PAGE>   8


Seller with the proceeds of Collections in respect of the Purchased Assets, in
satisfaction of the Deferred Purchase Price; PROVIDED that, from and after the
date that the Outstanding Balance of the Purchased Receivables is less than or
equal to 10% of the Outstanding Balance of the Purchased Receivables as of the
Termination Date, the Administrative Agent may, in lieu of continuing to make
such remittances, by at least three (3) Business Days' prior written notice to
the Seller, reassign to the Seller all of Triple-A's right, title and interest
in and to the Purchased Assets in full satisfaction of the Deferred Purchase
Price. It is expressly understood and agreed that the Deferred Purchase Price
shall be payable solely through Collections and other proceeds of the Purchased
Assets and that none of Triple-A, the Administrative Agent, the Collateral Agent
nor any Liquidity Bank shall have any personal liability for the payment of the
Deferred Purchase Price.

     (c)  SELECTION OF FIXED PERIODS. Promptly upon receiving each Sale Notice,
the Administrative Agent shall, following its review of the Seller's proposal,
select Fixed Periods for all Capital so that all outstanding Capital is at all
times allocated to a Fixed Period (it being understood that if the Seller does
not propose a specific Fixed Period, the Administrative Agent shall select such
Fixed Period in its discretion). The initial Fixed Period for any Capital shall
be specified in the Sale Notice described in SUBSECTION (A) hereof. At least one
Business Day prior to the last day of each Fixed Period for any Capital
allocated to such Fixed Period, the Seller shall request new Fixed Periods for
such Capital; PROVIDED that, in the case of any Fixed Period for Capital for
which Yield is to be determined by reference to the Eurodollar Rate, such
request shall be given not later than 10:00 A.M. (New York City time) at least
three (3) Business Days prior to the last day of the relevant Fixed Period. The
Administrative Agent shall, on the date of any Receivables Purchase hereunder
and, so long as any Capital related to such Receivables Purchase is outstanding,
on the first day of each successive Fixed Period for such Capital, notify the
Collateral Agent and the Seller of the duration of the relevant Fixed Period and
the Yield which will be applicable to the Capital during such Fixed Period. Any
Fixed Period that commences before the Termination Date and would otherwise end
on a date occurring after the Termination Date shall end on the Termination Date
and the duration of any Fixed Period that commences on or after the Termination
Date shall be of such duration as shall be selected by the Administrative Agent.
In addition, if a CP Disruption shall have occurred and be continuing, Triple-A,
or the Administrative Agent on its behalf, may, upon notice to the Originator
and the Seller, terminate any Fixed Period then in effect if Triple-A has funded
the Capital allocated to such Fixed Period by issuing Commercial Paper. All
outstanding Capital shall be assigned a Fixed Period at all times, which Fixed
Periods will be limited as set forth in the definition thereof.

     (d)  FUNDING. Triple-A shall, before 3:00 P.M. (New York City time) on the
proposed Receivables Purchase Date of each Receivables Purchase, subject to the
applicable conditions set forth in ARTICLE IV, make available to the Seller a
wire transfer of such funds to the Seller in accordance with the Seller's
written wire transfer instructions.

     SECTION 2.03. REDUCTION OF FACILITY LIMIT. The Seller shall have the right,
at any time upon at least three (3) Business Days' notice to Triple-A, to
terminate in whole or reduce in part the unused portion of the Facility Limit in
a minimum amount of $10,000,000 and


                                       4

<PAGE>   9


increments of $1,000,000 in excess thereof; PROVIDED that if the aggregate of
the simultaneous reductions in the Facility Limit hereunder and under the Credit
Agreement satisfy such test, the Seller may reduce the unused portion of the
Facility Limit hereunder in a minimum amount of $3,000,000 and increments of
$600,000 in excess thereof; PROVIDED, that in no event shall the Facility Limit
be reduced to less than the amount of Capital then outstanding. Any such
termination shall be without premium or penalty of any kind, except for any
indemnification which may be owed in connection with such termination pursuant
to SECTION 2.06 and SECTION 8.01.

          SECTION 2.04. SETTLEMENT PROCEDURES.

          (a)  Any Collections of Purchased Receivables received (or deemed to
have been received) by the Seller shall be remitted directly to Triple-A by
depositing such Collections in the Lock-Box Account within one Business Day of
Seller's receipt (or deemed receipt) thereof. On each Payment Date, the Seller
shall pay to Triple-A (i) Yield on all outstanding Capital the Fixed Period for
which ends on such date PLUS (ii) the CP Dealer Fees, if any, on any Commercial
Paper maturing on such date and raised to fund such Capital.

          (b)  On each Settlement Date to occur prior to the Designated
Termination Date, the Seller shall either:

          (i)  if Triple-A has consented thereto, sell additional Receivables
     hereunder in accordance with the procedures and subject to the conditions
     set forth in SECTION 2.01 such that, immediately following such Receivables
     Purchase, the Capital Limit equals or exceeds outstanding Capital, in which
     event the Collateral Agent shall, subject to the order of priority set
     forth in SECTION 6.11(b), remit the Collections so set aside to the Seller
     in consideration of the purchase price for such Receivables Purchase; or

          (ii) if Triple-A has not consented to such additional purchase, out of
     the Collections so set aside, direct the Collateral Agent to remit to the
     Administrative Agent, subject to the order of priority set forth in SECTION
     6.11, an amount of such Collections to be applied toward the reduction of
     outstanding Capital such that, following the application of such
     Collections to outstanding Capital, the Capital Limit equals or exceeds the
     outstanding Capital.

          (c)  On each Payment Date from and after the Designated Termination
Date, the Seller shall direct the Collateral Agent to distribute to the
Administrative Agent for the benefit of Triple-A, to be applied toward the
reduction of outstanding Capital, all Collections so set aside but not to exceed
the sum of (i) the Capital allocated to such Fixed Period, (ii) all accrued and
unpaid Yield thereon, and (iii) the aggregate of all other amounts owed
hereunder by the Seller to Triple-A and/or the Administrative Agent, all as more
fully set forth in SECTION 6.11.

          (d)  If on any day the Outstanding Balance of any Purchased Receivable
is either (i) reduced or adjusted as a result of any defective, rejected,
returned, repossessed or foreclosed merchandise, any defective or rejected
services, any cash discount or any other


                                       5

<PAGE>   10


adjustment made or performed by the Seller or any other Person (including,
without limitation, those described in the definition of "DILUTION FACTORS"), or
(ii) reduced or canceled as a result of a setoff in respect of any claim by the
Obligor thereof against the Seller or any other Person (whether such claim
arises out of the same or a related transaction or an unrelated transaction),
the Seller shall be deemed to have received on such day a Collection of such
Purchased Receivable in the amount of such reduction, cancellation or
adjustment. If on any day any of the representations or warranties in SECTION
4.01(g) is no longer true with respect to a Purchased Receivable or if the
Seller has breached its obligations under SECTION 5.01(j), then the Seller shall
be deemed to have received on such day a Collection of such Purchased
Receivable: (x) if such representation, warranty or covenant relates to the
non-existence of any Adverse Claims, the Seller shall be deemed to have received
a Collection of such Purchased Receivable in the dollar amount of the Adverse
Claims attaching thereto and (y) if such representation or warranty relates to
the validity or perfection of the transfer of such Purchased Receivable under
this Triple-A Purchase Agreement or the perfection of Triple-A's security
interest in any Equipment as against the Obligor thereunder, then the Seller be
deemed to have received a Collection of such Purchased Receivable in an amount
equal to the Outstanding Balance thereof. To the extent that any such deemed
Collection reduces the Outstanding Balance of such Purchased Receivable to zero,
then, upon the Seller's payment to the Collateral Agent of such deemed
Collection, the Collateral Agent shall re-assign to the Seller all of its right,
title and interest in and to the relevant Purchased Receivable, the Contract
under which such Purchased Receivable arose and the Related Security relating
thereto.

          (e)  Although the Originator, the Seller and Triple-A agree that the
Originator shall have no right to so terminate, reject or not assume a Contract,
if the Originator in its capacity as Servicer (or its successor in interest,
including a trustee appointed under the Bankruptcy Code) terminates, rejects or
does not assume a Contract, in whole or in part, prior to the expiration of the
original term of such Contract, whether such rejection, termination or
non-assumption is made pursuant to an equitable cause, statute, regulation,
judicial proceeding or other applicable law (including, without limitation,
Section 365 of the Bankruptcy Code), then (i) the Seller shall be deemed to have
received Collections with respect to Purchased Receivables arising under such
Contract in an amount equal to (A) in the event of a prepayment or termination
consented to by the Originator at the Obligor's request, the excess, if any, of
the Termination Amount over all amounts paid by the Obligor on account of such
termination or (B) in the event of any other rejection or non-assumption, the
amount, of the Outstanding Balance thereof that has not been, or may not be paid
as a result of such rejection, termination or non-assumption. Upon the Seller's
payment of any such deemed Collections described in this SECTION 2.05(e), the
Collateral Agent shall re-assign to the Seller all of its right, title and
interest in and to the relevant Purchased Receivable or Purchased Receivables,
the Contracts under which such Purchased Receivable(s) arose and the Related
Security relating thereto.

          SECTION 2.05. PAYMENTS AND COMPUTATIONS, ETC. All amounts to be paid
or deposited by the Seller hereunder shall be paid or deposited by the Seller in
immediately available funds to Triple-A not later than 1:00 P.M. (New York City
time) on the date on which payable. Payments received by Triple-A after such
time shall be deemed to have been received on the next Business Day. All
payments by the Seller under this Triple-A Purchase Agreement


                                       6

<PAGE>   11


shall be made without setoff, deduction or counterclaim and the Seller agrees to
pay on demand any present or future stamp or documentary taxes or any other
excise or property taxes, charges or similar levies which arise from any payment
made hereunder or from the execution, delivery or registration of, or otherwise
with respect to, this Triple-A Purchase Agreement. Whenever any payment to be
made hereunder shall be stated to be due on a day which is not a Business Day,
the due date thereof shall be extended to the next applicable Business Day and
interest shall be payable at the applicable rate during such extension;
PROVIDED, that if such extension would be inconsistent with one of the
provisions set forth in the definition of "Fixed Period", then such provision
shall control.

          SECTION 2.06. COMPENSATION. The Seller shall compensate Triple-A, upon
its written request, for all losses, expenses and liabilities, including,
without limitation, any indemnification payments owed by Triple-A pursuant to
the Liquidity Agreement, on account of any liquidation or reemployment of
deposits or other funds acquired by such party to make, fund or maintain Capital
hereunder, (i) if for any reason a Receivables Purchase does not occur on a date
specified therefor in the Sale Notice; (ii) if for any reason any payment,
prepayment or conversion of any Capital occurs on a date which is not the last
day of the Fixed Period for such Capital or (iii) as a consequence of any
required conversion of any Eurodollar Rate Advance prior to the last day of the
Fixed Period for the relevant Capital. Any request for compensation under this
SECTION 2.06 shall be accompanied by a copy of a statement from Triple-A setting
forth in reasonable detail the basis for requesting compensation and the
determination of the amount thereof in such statement shall be conclusive and
binding for all purposes, absent manifest error.

          SECTION 2.07. DIVIDING OR COMBINING OF CAPITAL AND FIXED PERIODS. The
Seller may, on notice to and with the consent of the Administrative Agent
received at least one Business Day prior to the last day of any Fixed Period,
either (a) divide such Capital so as to allocate such Capital to two or more
Fixed Periods, or (b) combine such Capital with other Capital originating on
such last day or having Fixed Periods ending on such last day so as to allocate
all such Capital to a single Fixed Period. On and after the Termination Date,
the Administrative Agent shall have the right to divide and/or combine Capital
for purposes of allocation to Fixed Periods in any manner which it may select in
its sole discretion.

          SECTION 2.08. INCREASED COSTS, CAPITAL ADEQUACY.

          (a)  If, after the date hereof due to either (i) the introduction of
or any change in or to the interpretation of any law or regulation by the
governmental authority that promulgated or administers compliance with such law
or regulation (other than laws or regulations with respect to income taxes or
any change by way of imposition or increase of reserve requirements included in
the Eurodollar Reserve Percentage) or (ii) the compliance with any guideline or
request from any central bank or other governmental authority or similar agency
(whether or not having the force of law), and taking into account the
obligations of the Liquidity Banks under the Liquidity Agreement and otherwise
in connection with Triple-A's asset-supported financing business, any reserve or
deposit or similar requirement shall be imposed, modified or deemed applicable
or, any basis of taxation shall be changed or any other



                                       7

<PAGE>   12


condition shall be imposed, and there shall be any increase in the cost to
Triple-A (either directly or indirectly through any increase in the costs to the
Liquidity Banks) of making, funding, or maintaining Receivables Purchases or in
the cost to Triple-A of agreeing to make, fund, or maintain Receivables
Purchases (including the reduction of any sum received or Receivable hereunder),
then the Seller shall from time to time, upon demand by Triple-A by the
submission of the certificate described below, pay to Triple-A additional
amounts sufficient to compensate Triple-A for such increased cost. A certificate
setting forth in reasonable detail the amount of such increased cost submitted
to the Seller by Triple-A shall be conclusive and binding for all purposes,
absent manifest error.

          (b)  If Triple-A or any Liquidity Bank determines that compliance with
any law or regulation or any guideline or request or any written interpretation
from any central bank or other governmental authority or similar agency (whether
or not having the force of law) which is introduced, implemented or received by
Triple-A or such Liquidity Bank after the date hereof, affects or would affect
capital adequacy or the amount of capital required or expected to be maintained
by Triple-A or such Liquidity Bank or any corporation controlling Triple-A or
such Liquidity Bank and that the amount of such capital is increased by or based
upon the Triple-A Loans or the existence of this Triple-A Purchase Agreement or
upon the Advances or such Liquidity Bank's commitment to lend under the
Liquidity Agreement and other commitments of that type, or has or would have the
effect of reducing the rate of return on capital, then, upon demand by Triple-A
by the submission of the certificate described below, the Seller shall pay to
Triple-A, from time to time as specified by Triple-A, additional amounts
sufficient to compensate Triple-A or such corporation in the light of such
circumstances, to the extent that Triple-A reasonably determines such increase
in capital to be allocable to the Receivables Purchases or the existence of this
Triple-A Purchase Agreement or to the extent that Triple-A owes compensation to
a Liquidity Bank in respect of or on account of such events. A certificate
setting forth in reasonable detail such amounts submitted to the Seller by
Triple-A shall be conclusive and binding for all purposes, absent manifest
error.

          (c)  In the event that Triple-A requests compensation for increased
costs on behalf of any Liquidity Bank under this SECTION 2.08 and such increased
costs are not being requested by the other Liquidity Banks generally or, if only
one Liquidity Bank exists, by Triple-A's liquidity providers for similar
transactions, then Triple-A shall, promptly following identification by the
Seller of an "Eligible Assignee" (as defined in the Liquidity Agreement) willing
to accept such commitment, cause the Liquidity Bank requesting such increased
costs to assign its outstanding Advances and commitments under the Liquidity
Agreement to such Eligible Assignee, all as more particularly described in
SECTION 8.06(g) of the Liquidity Agreement.

          SECTION 2.09. TAXES. (a) All payments made by the Seller under this
Triple-A Purchase Agreement shall be made free and clear of, and without
deduction or withholding for or on account of, any present or future taxes,
levies, imposts, duties, charges, fees, deductions or withholdings, now or
hereafter imposed, levied, collected, withheld or assessed by any governmental
authority having taxing authority, excluding net income taxes and franchise
taxes (imposed in lieu of income taxes) imposed on Triple-A, as a result of any
present or former


                                       8

<PAGE>   13


connection between the jurisdiction of the government or taxing authority
imposing such tax or any political subdivision or taxing authority thereof or
therein and Triple-A (excluding a connection arising solely from Triple-A having
executed, delivered or performed its obligations or received a payment under, or
enforced, this Triple-A Purchase Agreement) (all such non-excluded taxes,
levies, imposts, duties, charges, fees, deductions and withholdings being
hereinafter called "TAXES"). If any Taxes are required to be withheld from any
amounts payable by the Seller, (i) the sum payable shall be increased as may be
necessary so that, after making all required deductions (including deductions
applicable to additional sums payable under this SECTION 2.09), Triple-A
receives an amount equal to the sum it would have received had no such
deductions been made, (ii) the Seller shall make such deductions, and (iii) the
Seller shall pay the full amount deducted to the relevant taxation authority or
other authority in accordance with applicable law.

          (b)  In addition, the Seller agrees to pay any present or future stamp
or documentary taxes or any other excise or property taxes, charges, or similar
levies that arise from any payment made hereunder or from the execution,
delivery or registration of, or otherwise with respect to, this Triple-A
Purchase Agreement (hereinafter "OTHER TAXES").

          (c)  The Seller will indemnify Triple-A for the full amount of Taxes
or Other Taxes (including, without limitation, any Taxes or Other Taxes imposed
by any jurisdiction on amounts payable under this SECTION 2.09) paid by Triple-A
and any liability (including penalties, interest and expenses) arising therefrom
or with respect thereto. Whenever any Taxes are payable by the Seller, as
promptly as possible thereafter the Seller shall send to Triple-A, a certified
copy of an original official receipt received by the Seller showing payment
thereof. If the Seller fails to pay any Taxes when due to the appropriate taxing
authority or fails to remit to Triple-A the required receipts or other required
documentary evidence, the Seller shall indemnify Triple-A for any incremental
Taxes, interest or penalties that Triple-A is legally required to pay as a
result of any such failure. The agreements in this subsection shall survive the
termination of this Triple-A Purchase Agreement.

          SECTION 2.10. FEES. In further consideration of the Receivables
Purchases to be made hereunder, the Seller agrees to pay to the Administrative
Agent and Triple-A all fees specified in the Fee Letter of even date herewith,
which fees will be due and payable at the times and in the manner set forth in
such Fee Letter.

          SECTION 2.11. GRANT OF SECURITY INTEREST IN EQUIPMENT COLLATERAL. (a)
As security for the payment and performance of all the obligations of the Seller
hereunder and as additional enhancement to enable Triple-A, the Liquidity Banks
and CapMAC to fully recover Capital and accrued and unpaid Yield and fees, the
Seller hereby grants to the Collateral Agent, for the benefit of Triple-A, the
Liquidity Banks and CapMAC, a security interest in all of the Seller's right,
title and interest in and to the following, whether now owned or hereafter
acquired and whether now existing or hereafter arising (the "EQUIPMENT
COLLATERAL"): all Equipment which is the subject of a Contract for any Purchased
Receivable and substitutions therefor and products and proceeds thereof,
including, without limitation, all payments under insurance (whether or not the
Collateral Agent is the loss payee thereof) or any indemnity, warranty or



                                       9

<PAGE>   14

guaranty, payable by reason of loss or damage to or otherwise with respect to
any of the foregoing.

          (b)  The Seller shall, at its expense, promptly execute and deliver
all further instruments and documents, and take all further action (including,
without limitation, the execution and filing of such financing or continuation
statements, or amendments thereto and assignments thereof), that may reasonably
be necessary or desirable, or that the Administrative Agent may request, in
order to perfect and protect any security interest granted or purported to be
granted to the Collateral Agent hereunder or to enable the Collateral Agent to
exercise and enforce its rights and remedies hereunder with respect to any
Equipment Collateral. The Seller hereby authorizes the Collateral Agent to file
one or more financing or continuation statements, and amendments thereto and
assignments thereof, relative to all or any part of the Equipment Collateral now
existing or hereafter arising without the signature of the Seller where
permitted by law. A carbon, photographic or other reproduction of the Triple-A
Purchase Agreement of any financing statement covering the Equipment Collateral
or any part thereof shall be sufficient as a financing statement.

                         REPRESENTATIONS AND WARRANTIES

          SECTION 4.01. REPRESENTATIONS AND WARRANTIES OF THE SELLER. The Seller
represents and warrants to Triple-A that:

          (a)  DUE INCORPORATION AND GOOD STANDING. The Seller is a corporation
duly organized, validly existing and in good standing under the laws of its
jurisdiction of incorporation. The Seller is duly qualified to do business as a
foreign corporation and is in good standing in every jurisdiction in which the
nature of its business requires it to be so qualified or where the ownership of
its properties or the nature of its activities makes such qualification
necessary, except where the failure to be so qualified would not materially
adversely affect (i) the collectibility of the Purchased Assets, (ii) the
collectibility of any Receivable, (iii) the business, properties, operations,
prospects, profits or condition (financial or otherwise) of the Seller or (iv)
the ability of the Seller to perform its obligations hereunder and under the
other Facility Documents to which it is a party.

          (b)  DUE AUTHORIZATION AND NO CONFLICT. The execution, delivery and
performance by the Seller of this Triple-A Purchase Agreement and all other
Facility Documents and the transactions contemplated hereby and thereby,
including the acquisition of the Transferred Assets under the Purchase Agreement
and the purchases contemplated hereunder, are within the Seller's corporate
powers, have been duly authorized by all necessary corporate action, do not
contravene (i) the Seller's charter or by-laws, (ii) any law, rule or regulation
applicable to the Seller, (iii) any contractual restriction contained in any
indenture, loan or credit agreement, lease, mortgage, security agreement, bond,
note, or other agreement or instrument binding on or affecting the Seller or its
property or (iv) any order, writ, judgment, award, injunction or decree binding
on or affecting the Seller or its property, and do not result in or require the
creation of any Adverse Claim upon or with respect to any of its properties; and
no transaction contemplated hereby requires compliance with any bulk sales act
or similar law. This Triple-A Purchase Agreement and the other Facility
Documents to which the Seller is a party have been duly executed and delivered
on behalf of the Seller.

          (c)  GOVERNMENTAL AND OTHER CONSENTS. Except for the filing of
financing statements pursuant to the UCC required to perfect the security
interests granted hereunder or under the other Facility Documents and except for
consents under certain contractual agreements which have been obtained, no
authorization, consent, approval or other action by, and no registration,
qualification, designation, declaration, notice to or filing with, any
governmental authority or other Person is or will be necessary in connection
with the execution and delivery of this Triple-A Purchase Agreement or any other
Facility Document to which the Seller is a party or any of the other documents
contemplated hereby or thereby, consummation of the transactions herein or
therein contemplated, or performance of or compliance with the terms and
conditions hereof or thereof, to ensure the legality, validity or enforceability
hereof or thereof.

          (d)  ENFORCEABILITY OF FACILITY DOCUMENTS. This Triple-A Purchase
Agreement and each of the other Facility Documents to which the Seller is a
party have been duly and validly executed and delivered by the Seller and
constitute the legal, valid and binding obligation of the Seller enforceable in
accordance with their respective terms, except as enforceability may be limited
by bankruptcy, insolvency or similar laws relating to or affecting creditors'
rights generally and by equitable principles.

          (e)  NO LITIGATION. There are no actions, suits or proceedings at law
or in equity or by or before any governmental authority now pending or, to the
knowledge of the Seller, threatened against or affecting the Seller or any
property or rights of the Seller which purport to challenge the legality,
validity or enforceability of this Triple-A Purchase Agreement or any other
Facility Document or which may materially impair the ability of the Seller to
carry on business substantially as now being conducted or which may materially
adversely affect the condition (financial or otherwise), operations or
properties of the Seller.

          (f)  USE OF PROCEEDS. No proceeds of any Receivables Purchase will be
used by the Seller other than to fund a Purchase of Transferred Assets from the
Originator except that the Seller may net from the Purchase Price paid to the
Originator reasonable and necessary amounts for the funding of its operating
expenses.

          (g)  VALID TITLE AND PERFECTED INTEREST. Each Receivable, together
with the Contract related thereto, is owned by the Seller free and clear of any
Adverse Claim except as provided herein or in the Credit Agreement and, upon the
making of each Receivables Purchase, Triple-A shall acquire a valid and
perfected first priority undivided percentage ownership interest, to the extent
of the Purchased Assets, in each Purchased Receivable then existing or
thereafter arising and in the Related Security and Collections with respect
thereto, in each case free and clear of any Adverse Claim except as provided
hereunder or under the Credit Agreement, the Liquidity Agreement or the
Liquidity Security Agreement (except that the Collateral Agent will not have a
perfected security interest in any Collateral constituting Equipment which is
owned by the Seller and located in a state other than The Commonwealth of
Massachusetts); and no effective financing statement or other instrument similar
in effect covering any Purchased Receivable or the Related Security or
Collections with respect thereto shall at any time be filed except in favor of
the Collateral Agent in accordance with this Triple-A Purchase Agreement and the
Credit Agreement.

          (h)  ACCURACY OF INFORMATION. All certificates, reports, financial
statements and similar writings furnished by or on behalf of the Seller to
Triple-A, the Collateral Agent, or the Administrative Agent at any time pursuant
to any requirement of, or in response to any written request of any such party
under, this Triple-A Purchase Agreement or any other Facility Document or any
transaction contemplated hereby or thereby, have been, and all such
certificates, reports, financial statements and similar writings hereafter
furnished by the Seller to such parties will be, true and accurate in every
respect material to the transactions contemplated hereby on the date as of which
any such certificate, report, financial statement or similar writing was or will
be delivered, and shall not omit to state any material facts or any facts
necessary to make the statements contained therein not materially misleading.

          (i)  GOVERNMENTAL REGULATIONS. The Seller is not an "investment
company" or a company controlled by an "investment company" registered or
required to be registered under the Investment Company Act of 1940, as amended,
or otherwise subject to any other federal or state statute or regulation
limiting its ability to incur indebtedness.

          (j)  MARGIN REGULATIONS. The Seller is not engaged, principally or as
one of its important activities, in the business of extending credit for the
purpose of "purchasing" or "carrying" any "margin stock" (as each of the quoted
terms is defined or used in Regulation T, U or X). No part of the proceeds of
any Receivables Purchase has been used for so purchasing or carrying margin
stock or for any purpose which violates, or which would be inconsistent with,
the provisions of Regulation T, U or X.

          (k)  LOCATION OF CHIEF EXECUTIVE OFFICE AND RECORDS. The chief place
of business and chief executive office of the Seller are located at the address
referred to in EXHIBIT D hereof and the locations of the offices where the
Seller keeps all the Records are listed on EXHIBIT D (or at such other

completed).

          (l)  LOCK-BOX ACCOUNTS. Each Obligor under a Contract has, within one
month of the date of Purchase of such Contract, been instructed to remit payment
on the Receivables to a Post Office Box for remittance to a Lock-Box Account or

Purchase Agreement. From and after the initial Purchase Date, the Originator
will have no right, title and/or interest to any of the Lock-Box Accounts and
will maintain no lock-box accounts in its own name for the collection of such
Receivables. The Seller has caused the Originator to deliver to the Collateral
Agent a duplicate key to each Post Office Box and has filed a standing delivery
order with the United States Postal Service authorizing the Collateral Agent to
receive mail delivered to each such Post Office Box. The account numbers of all
Lock-Box Accounts, together with the names and addresses of all the Lock-Box
Banks maintaining such Lock-Box Accounts and the related Post Office Boxes, are
specified in EXHIBIT H to the Purchase Agreement. The Seller has no other
Lock-Box Accounts for the collection of the Transferred Assets except for the
Lock-Box Accounts.

own board of directors, (ii) has at least one director who is reasonably

manner which facilitates their identification and segregation from those of its
Affiliates, and has a separate telephone number from that of the Originator or

                                       15

<PAGE>   20


equipment are either owned by the Seller or leased pursuant to written leases,
(v) conducts all intercompany transactions with the Originator and each other
Subsidiary of the Originator on terms which the Seller reasonably believes to be
on an arm's-length basis, (vi) has not guaranteed any obligation of the
Originator or any other Subsidiary of the Originator, nor has it had any of its
obligations guaranteed by any such entities and has not held itself out as
responsible for debts of any such entity or for the decisions or actions with
respect to the business and affairs of any such entity, (vii) has not, except as
otherwise expressly acknowledged under the Facility Documents, permitted the
commingling or pooling of its funds or other assets with the assets of the

allocate among themselves shared corporate operating services and expenses which
are not reflected in the Servicing Fee (including, without limitation, the
services of shared employees, consultants and agents and reasonable legal and
auditing expenses) on the basis of actual use or the value of services rendered,
and otherwise on a basis reasonably related to actual use or the value of
services rendered, (xii) pays directly for its own account for accounting and
payroll services, rent, lease and other expenses and does not have such
operating expenses paid by the Originator or any other Subsidiary of the
Originator, (xiii) conducts all of its business (whether in writing or orally)
solely in its own name, (xiv) is not, directly or indirectly, named as a direct
or contingent beneficiary or loss payee on any insurance policy covering the
property of the Originator or any other Subsidiary of the Originator and has
entered into no agreement to be named as such a beneficiary or payee, (xv)
acknowledges that Triple-A, the Administrative Agent, the Surety and the
Liquidity Banks are entering into the transactions contemplated by this Triple-A
Purchase Agreement and the other Facility Documents in reliance on the Seller's
identity as a separate legal entity from the Originator and each other
Subsidiary of the Originator, and (xvi) practices and adheres to corporate
formalities such as complying with its By-laws and corporate resolutions and the
holding of regularly scheduled board of directors meetings.

          (o)  SUBSIDIARIES. The Seller has no Subsidiaries and does not own or
hold, directly or indirectly, any capital stock or equity security of, or any
equity interest in, any Person.

          (p)  FACILITY DOCUMENTS. The Purchase Agreement is the only agreement
pursuant to which the Seller purchases Receivables or other Transferred Assets.
The Seller has furnished to Triple-A true, correct and complete copies of each
Facility Document to which the Seller is a party, each of which is in full force
and effect. Neither the Seller nor any Affiliate thereof is in default of any of
its obligations thereunder in any material respect. Upon the Purchase of each
Receivable pursuant to the Purchase Agreement, the Seller shall be the lawful
owner of, and have good title to, such Receivable and all Transferred Assets
relating thereto, free and clear of any Adverse Claims. All such Transferred
Assets are purchased without recourse to the Originator except as described in
the Purchase Agreement. The Purchases of the Transferred Assets by the Seller
constitute valid and true sales and transfers for consideration (and not merely


                                       16

<PAGE>   21


a pledge of such Transferred Assets for security purposes), enforceable against
creditors of the Originator and no Transferred Assets shall constitute property
of the Originator.

          (q)  BUSINESS. Since its incorporation, the Seller has conducted no
business other than the execution, delivery and performance of the Facility
Documents contemplated hereby, the purchase and servicing of Transferred Assets
thereunder, and such other activities as are incidental to the foregoing. The
Seller has incurred no Indebtedness except that expressly incurred hereunder and
under the other Facility Documents.

          (r)  OWNERSHIP OF THE SELLER. One hundred percent (100%) of the
outstanding capital stock of the Seller is directly owned (both beneficially and
of record) by HPSC, Inc. Such stock is validly issued, fully paid and
nonassessable and there are no options, warrants or other rights to acquire
capital stock from the Seller.

          (s)  TAXES. The Seller has filed or caused to be filed all Federal,
state and local tax returns which are required to be filed by it, and has paid
or caused to be paid all taxes shown to be due and payable on such returns or on
any assessments received by it, other than any taxes or assessments, the
validity of which are being contested in good faith by appropriate proceedings
and with respect to which the Seller has set aside adequate reserves on its
books in accordance with GAAP and which proceedings have not given rise to any
Adverse Claim.

          (t)  SOLVENCY. The Seller, both prior to and after giving effect to
the initial Purchase on the initial Purchase Date, and after giving effect to
each subsequent Purchase, (i) is not "insolvent" (as such term is defined in
ss.101(31)(A) of the Bankruptcy Code); (ii) is able to pay its debts as they
become due; and (iii) does not have unreasonably small capital for the business
in which it is engaged or for any business or transaction in which it is about
to engage.

          (u)  DIVERSIFICATION. After giving effect to the initial Receivables
Purchase on the initial Receivables Purchase Date, the number of Contracts and
the number of Obligors associated with the Purchased Receivables shall equal or
exceed 300.

          (v)  AVERAGE OUTSTANDING BALANCE. After giving effect to the initial
Receivables Purchase on the initial Receivables Purchase Date, and immediately
after giving effect to each subsequent Receivables Purchase, the average
Outstanding Balance of all Purchased Receivables hereunder shall not be less
than 90% nor more than 110% of the average "Outstanding Balance" of "Pledged
Receivables" (as each term is defined in the Definitions List to the Credit
Agreement).

          (x)  IMPLICIT INTEREST RATE. As of the date of any Receivables
Purchase, the excess of (i) the average implicit interest rates being charged to
Obligors in respect of the Receivables then being purchased OVER (ii) the
Discount Rate applicable to such Receivables, shall not be greater than eight
percent (8.0%).

          (y)  SELECTION OF RECEIVABLES. Each Receivable has been randomly
selected from the Originator's portfolio of receivables in accordance with its
normal standards and procedures used for all of its standard securitization
transactions and no selection procedures


                                       17


<PAGE>   22


adverse to Triple-A have been employed in such selections. In addition, (i) the
designation of a Purchased Receivable as a Designated Receivable or a
Non-Designated Receivable and (ii) the repurchase of any Designated Receivable
pursuant to Section 8.02 shall be done on a basis which is not adverse to
Triple-A or CapMAC.

          (z)  HISTORIC LOSS DATA. Attached hereto as EXHIBIT F is a summary of
historical static loss data suffered by the Originator as a result of
charge-offs of the Originator's receivables, which summary is true and accurate
with respect to the periods described therein and does not omit any information
necessary to make such summary not misleading.

                                    ARTICLE V

                                GENERAL COVENANTS

          SECTION 5.01. AFFIRMATIVE COVENANTS OF THE SELLER. From the initial
Receivables Purchase Date until the later of the Termination Date or the
Collection Date, the Seller will, unless Triple-A shall otherwise consent in
writing:

          (a)  COMPLIANCE WITH LAWS, ETC. Comply in all material respects with
all applicable laws, rules, regulations and orders with respect to it, its
business and properties and all Receivables and related Contracts.

          (b)  PRESERVATION OF CORPORATE EXISTENCE. Preserve and maintain its
corporate existence, rights, franchises and privileges in the jurisdiction of
its incorporation, and qualify and remain qualified in good standing as a
foreign corporation in each jurisdiction except where the failure to preserve
and maintain such existence, rights, franchises, privileges and qualifications
would not materially adversely affect (i) the collectibility of the Purchased
Assets, (ii) the collectibility of any Receivable, (iii) the business,
properties, operations, prospects, profits or condition (financial or otherwise)
condition of the Seller or (iv) the ability of the Seller to perform its
obligations hereunder and under the other Facility Documents to which it is a
party.

          (c)  AUDITS. At any time and from time to time upon prior written
notice to the Seller during regular business hours and on a quarterly basis if
requested, permit the Collateral Agent, or its agents or representatives, (i) to
examine and make copies of and abstracts from all Records, and (ii) to visit the
offices and properties of the Seller for the purpose of examining such Records,
and to discuss matters relating to the Receivables or the Seller's performance
hereunder with any of the officers or employees of the Seller having knowledge
of such matters. Each such audit shall be at the sole expense of the Seller
(subject to the Seller's right under the Purchase Agreement to recover such
expenses from the Originator); PROVIDED, that, so long as no Wind-Down Event has
occurred during any calendar year, the annual audit expenses during such year
for which the Seller is responsible hereunder and under the Credit Agreement
shall not exceed $40,000 in the aggregate.

          (d)  KEEPING OF RECORDS AND BOOKS OF ACCOUNT. Maintain and implement
administrative and operating procedures (including, without limitation, an
ability to recreate records evidencing the Receivables in the event of the
destruction of the originals thereof) and


                                       18


<PAGE>   23


keep and maintain, all documents, books, records and other information
reasonably necessary or advisable for the collection of all Receivables
(including, without limitation, records adequate to permit the daily
identification of all collections of and adjustments to each Purchased
Receivable).

          (e)  PERFORMANCE AND COMPLIANCE WITH RECEIVABLES AND CONTRACTS. At its
expense timely and fully perform and comply, and cause the Originator to comply,
in all material respects, with all material provisions, covenants and other
promises required to be observed by it or the Originator under the Contracts.

          (f)  LOCATION OF RECORDS. Keep its chief place of business and chief
executive office, and the offices where it keeps the Records, at the address of
the Seller referred to in SECTION 4.01(j), or, in any such case, upon 30 days'
prior written notice to the Collateral Agent, at such other locations within the
United States where all action required by SECTION 6.04 shall have been taken
and completed.

          (g)  CREDIT AND COLLECTION POLICIES. Comply in all material respects
with the Credit and Collection Policy in regard to each Purchased Receivable and
the related Contract.

          (h)  COLLECTIONS. Instruct all Obligors to cause all Collections to be
deposited directly to a Post Office Box or Lock-Box Account and if the Seller
shall receive any Collections, the Seller shall hold such Collections in trust
for the benefit of the Collateral Agent and deposit such Collections into a
Lock-Box Account or the Collection Account within one Business Day following
Seller's receipt thereof.

          (i)  COMPLIANCE WITH ERISA. Comply in all material respects with the
provisions of ERISA, the IRC, and all other applicable laws, and the regulations
and interpretations thereunder.

          (j)  PERFECTED SECURITY INTEREST UNDER CONTRACTS. Take such action
with respect to each Purchased Receivable as is necessary to ensure that the
Seller maintains, as against the Obligor thereunder, a perfected security
interest in any Equipment relating thereto free and clear of Adverse Claims or,
in the case of any Lease, to ensure that the Seller would maintain such a
perfected priority security interest in the event that a court or other Person
were to determine that such Lease purported to transfer to the Obligor an
ownership (rather than a leasehold) interest in the Equipment subject thereto;
PROVIDED, that the Seller shall not be required to file financing statements or
to maintain the effectiveness of previously filed financing statements with
respect to any Eligible Receivables the Outstanding Balance of which originally
is or has thereafter been reduced below $5,000, respectively, so long as the
aggregate Outstanding Balance of Receivables hereunder for which no such
financing statements are in effect at any time remains less than 7.5% of the
Discounted Eligible Receivables Balance hereunder; provided that such seven and
one-half percent limitation shall not apply from and after the Termination Date
unless and to the extent that the Collateral Agent specifically requests
otherwise.

          (k)  MAINTENANCE OF INSURANCE. Maintain, or cause the Originator or
each Obligor to maintain, with respect to the Contracts and the Equipment
related thereto, casualty


                                       19


<PAGE>   24

and general liability insurance which provide at least the same coverage as a
fire and extended coverage insurance policy as is comparable for other companies
in related businesses. Such insurance policies (and self-insurance where
permitted) shall be maintained in an amount which is not less than the aggregate
Discounted Value of the Purchased Receivables hereunder arising under the
relevant Contracts hereunder. Each such casualty and liability policy if
maintained by an Obligor, shall name the Originator or the Seller as loss payee
and additional insured, and the Originator shall have assigned any such interest
to the Seller. The Seller shall remit, or shall cause to be remitted, the
proceeds of any such insurance policy to a Lock-Box Account or the Collection
Account.

          (l)  SEPARATE IDENTITY. Take all actions required to maintain the
Seller's status as a separate legal entity. Without limiting the foregoing, the
Seller shall:

          (i) conduct all of its business, and make all communications to third
     parties (including all invoices (if any), letters, checks and other
     instruments) solely in its own name (and not as a division of any other
     Person), and require that its employees, if any, when conducting its
     business identify themselves as such and not as employees of any other
     Affiliate of the Seller (including, without limitation, by means of
     providing appropriate employees with business or identification cards
     identifying such employees as the Seller's employees);

          (ii) compensate all employees, consultants and agents directly or
     indirectly through reimbursement of the Originator each calendar quarter,
     from the Seller's bank accounts, for services provided to the Seller by
     such employees, consultants and agents and, to the extent any employee,
     consultant or agent of the Seller is also an employee, consultant or agent
     of any Affiliate of the Seller, allocate the compensation of such employee,
     consultant or agent between the Seller and such Affiliate on a basis which
     reflects the services rendered to the Seller and such Affiliate;

          (iii) pay its own operating expenses and liabilities from its own
     funds, allocate all overhead expenses (including, without limitation,
     telephone and other utility charges) for items shared between the Seller
     and any Affiliate on the basis of actual use to the extent practicable and,
     to the extent such allocation is not practicable, on a basis reasonably
     related to actual use and allocate taxes on the basis of their respective
     incomes in accordance with applicable federal regulations;

          (iv) at all times have at least one "Independent Director", as defined
     in and as required under the Seller's Certificate of Incorporation and have
     at least one officer responsible for managing its day-to-day business and
     manage such business by or under the direction of its board of directors;

          (v) maintain its books and records separate from those of any
     Affiliate;

          (vi) prepare its financial statements separately from those of its
     other Affiliates and insure that any consolidated financial statements of
     the Originator have notes to the effect that the Seller is a separate
     corporate entity whose creditors have a claim on its


                                       20

<PAGE>   25

     assets prior to those assets becoming available to its equity holders and
     therefore to any creditors of the Originator;

          (vii) use its best efforts not to commingle its funds or other assets
     with those of any other Affiliate, and not to hold its assets in any manner
     that would create an appearance that such assets belong to any other
     Affiliate, and not maintain bank accounts or other depository accounts to
     which any Affiliate is an account party, into which any Affiliate makes
     deposits or from which any Affiliate has the power to make withdrawals;

          (viii) not permit any Affiliate to pay its operating expenses (except
     pursuant to allocation arrangements that comply with the requirements of
     SUBSECTION (II) or (III) of this SECTION 5.01(l) or pursuant to the terms
     of the Purchase Agreement);

          (ix) not guarantee any obligation of any Affiliate nor (to the extent
     that the Seller has the legal power to prevent such) have any of its
     obligations guaranteed by any such Affiliate, (either directly or by
     seeking credit based on the assets of such Affiliate) or otherwise hold
     itself out as responsible for the debts of any Affiliate;

          (x) maintain at all times stationery and a telephone number separate
     from that of any Affiliate and which telephone number will be answered in
     its own name, and have all its officers and employees conduct all of its
     business solely in its own name;

          (xi) hold regular meetings of its board of directors in accordance
     with the provisions of its Certificate of Incorporation and otherwise take
     such actions as are necessary on its part to ensure that all corporate
     procedures required by its Certificate of Incorporation and by-laws are
     duly and validly taken;

          (xii) maintain a separate office from the offices of any of its
     Affiliates and identify such office by a sign in its own name;

          (xiii) pay dividends only if (A) no other dividend has been paid
     during the calendar month in which such dividend is paid, (B) such dividend
     has been duly authorized by its board of directors in accordance with
     applicable law and (C) its net worth, determined immediately after giving
     effect to such dividend is at least $2,000,000; and

          (xiv) take such other actions as are necessary on its part to ensure
     that the facts and assumptions set forth in the opinion described in
     SECTION 3.01(x) remain true and correct at all times.

          (m)  TAXES. File or cause to be filed, and (to the extent it has legal
power to cause such) cause each of its Affiliates with whom it shares
consolidated tax liability to file, all federal, state and local tax returns
which are required to be filed by it, except where the failure to file such
returns could not reasonably be expected to have a material adverse effect on
the collectibility of the Transferred Assets or the ability of the Seller to
perform its obligations hereunder or under any other Facility Document to which
it is a party or which could otherwise


                                       21

be reasonably expected to expose the Seller to a material liability. The Seller
shall pay or cause to be paid all taxes shown to be due and payable on such
returns or on any assessments received by it, other than any taxes or
assessments, the validity of which are being contested in good faith by
appropriate proceedings and with respect to which the Seller or the applicable
subsidiary shall have set aside adequate reserves on its books in accordance
with GAAP and which proceedings could not reasonably be expected to have a
material adverse effect on the collectibility of the Transferred Assets or the
ability of the Seller to perform its obligations hereunder or under any other
Facility Document to which it is a party or which could otherwise be reasonably
expected to expose the Seller to a material liability.

          (n)  INTEREST RATE HEDGES. Concurrently with each Receivables
Purchase, enter into an Interest Rate Hedge with the Swap Provider as
contemplated in the definition of "Discount Rate", and transfer, assign and
otherwise convey to the Collateral Agent all of the Seller's rights in, to and
under such Interest Rate Hedge pursuant to an Interest Rate Hedge Assignment in
substantially in the form of EXHIBIT E hereto, together with a certificate
executed by the Swap Provider in substantially the form of Exhibit A to such
Interest Rate Hedge Assignment. The Seller shall thereafter maintain such
Interest Rate Hedges in full force and effect at all times until the Capital
associated with such Receivables Purchase has been recovered in full by
Triple-A, in a notional amount equal to no less than 96% and no more than 105%
of the sum of the outstanding Capital plus the principal amount of all "Triple-A
Loans" (as defined in the Credit Agreement) related thereto and based on an
amortization schedule which matches the amortization of the aggregate
Receivables then outstanding and the terms of which are otherwise reasonably
satisfactory to the Collateral Agent. The Seller acknowledges that Triple-A
and/or the Surety on behalf of Triple-A have guaranteed the Seller's performance
of its obligations under the Interest Rate Hedges. The Seller shall perform all
of its obligations under the Interest Rate Hedges to the same extent as if its
rights under the Interest Rate Hedges has not been assigned hereunder and shall
indemnify each of Triple-A and the Surety against any payments by either such
party on account of the Seller's failure to perform its obligations under the
Interest Rate Hedges, including, without limitation, any payments by the Surety
under the Swap Bond, which indemnity shall survive any termination of this
Triple-A Purchase Agreement or the Credit Agreement. The exercise by the
Collateral Agent of any of its rights hereunder or under the Interest Rate Hedge
Assignment shall not relieve the Seller from such obligations.

          (o)  FACILITY DOCUMENTS. Comply in all material respects with the
terms of and employ the procedures outlined in and enforce the obligations of
the Originator under the Purchase Agreement, and all of the other Facility
Documents to which it is a party, take all such action to such end as may be
from time to time reasonably requested by the Collateral Agent, maintain all
such Facility Documents in full force and effect and make to the Originator such
reasonable demands and requests for information and reports or for action as the
Seller is entitled to make thereunder and as may be from time to time reasonably
requested by the Collateral Agent.

          (p)  SEGREGATION OF COLLECTIONS. Prevent the deposit into any of the
Lock-Box Accounts of any funds other than Collections in respect of the
Transferred Assets and, to the extent that any such funds are nevertheless
deposited into any of such Lock-Box Accounts,



                                       22

<PAGE>   27

to the owner thereof.

records or reports respecting the Purchased Receivables or the conditions or
operations, financial or otherwise, of the Seller as the Collateral Agent may

Collateral Agent or of Triple-A under or as contemplated by this Triple-A
Purchase Agreement.

Obligor upon or with respect to any Equipment owned by such Obligor so long as
such Adverse Claim is subordinate to the security interest of the Seller in such
Equipment.

          (b)  EXTENSION OR AMENDMENT OF RECEIVABLES. Except for actions of the
Servicer otherwise permitted hereunder and in the Purchase Agreement, extend,
amend or otherwise modify, the terms of any Receivable, or amend, modify or

change in the character of its business or in the Credit and Collection Policy,

deficiencies, payments, terminations and reportable events described in clauses
(i) through (iv) above so long as such events occurring within any fiscal year
of the Seller, in the aggregate, involve a payment of money by or an incurrence
of liability of any such ERISA Affiliate in an amount which does not exceed
$500,000.

          (h)  TERMINATE OR REJECT CONTRACTS. Without limiting SECTION 5.03(b),
terminate or reject any Contract prior to the term of such Contract, whether
such rejection or early termination is made pursuant to an equitable cause,
statute, regulation, judicial proceeding or other applicable law (including,
without limitation, Section 365 of the Bankruptcy Code), unless prior to such
termination or rejection, the Seller pays the Collateral Agent, for the benefit
of Triple-A, an amount equal to the Termination Amount owed with respect

Collateral Agent, or any Liquidity Bank as provided for under this Triple-A
Purchase Agreement or under the Credit Agreement.

          (k)  LIMITATION ON TRANSACTIONS WITH AFFILIATES. Enter into, or be a
party to any transaction with any Affiliate, except for:


                                       25

<PAGE>   30

          (i) the transactions contemplated by the Purchase Agreement;

for certain actions to be taken "with the consent of the Buyer", "acceptable to

contemplated by or incidental to the performance of its obligations under the
Facility Documents.

          (o)  ACCOUNTING TREATMENT. Prepare any financial statements or other
statements (including any tax filings which are not consolidated with those of
the Originator) which shall account for the transactions contemplated by the
Purchase Agreement in any manner other than as the sale of, or a capital
contribution of, the Transferred Assets by the Originator to the Seller (it
being understood that non-recognition of such transaction due to the application
of consolidated financial reporting principles under GAAP or the filing of tax
returns on a consolidated basis shall not constitute a violation of this
covenant).

          (p)  LIMITATION ON INVESTMENTS. Make or suffer to exist any loans or
advances to, or extend any credit to, or make any investments (by way of
transfer of property, contributions to capital, purchase of stock or securities

aggregate outstanding Capital

                                       26

<PAGE>   31

hereunder is less than the Capital Limit then in effect, the acceptance of
investments in exchange for Defaulted Receivables in an effort to maximize the
recoveries thereon.

                                   ARTICLE VI

                          ADMINISTRATION AND COLLECTION

          SECTION 6.01. DESIGNATION OF SERVICER. The servicing, administering
and collection of the Purchased Receivables and the other Purchased Assets shall
be conducted by the Person (the "SERVICER") designated by the Collateral Agent
from time to time in accordance with this SECTION 6.01. Until the Collateral
Agent gives notice to the Originator of the designation of a new Servicer, the
Originator is hereby designated as, and hereby agrees to perform the duties and
obligations of, the Servicer pursuant to the terms hereof. The Collateral Agent
may at any time from and after a Servicing Termination Event, or earlier upon
the written request of the Seller, designate as Servicer any other Person to
succeed the Originator or any Successor Servicer, on the condition in each case
that any such Person so designated shall agree to perform the duties and
obligations of the Servicer pursuant to the terms hereof. The Servicer may, with
the prior written consent of Triple-A and the Collateral Agent, subcontract with
any other Person for servicing, administering or collecting the Purchased
Assets, provided that the Servicer shall remain liable for the performance of
the duties and obligations of the Servicer pursuant to the terms hereof. The
Servicer shall use reasonable care in performing its duties as Servicer
hereunder and, without limiting the foregoing, shall service the Purchased
Receivables in accordance with the Credit and Collection Policy.

          SECTION 6.02. DUTIES OF THE SERVICER. (a) The Servicer shall take or
cause to be taken all such actions as may be necessary or advisable to collect
each Purchased Receivables from time to time, all in accordance with applicable
laws, rules and regulations, with reasonable care and diligence, and in
accordance with the Credit and Collection Policy. Each of the Seller, Triple-A,
the Administrative Agent and the Collateral Agent hereby appoints as its agent
the Servicer, from time to time designated pursuant to SECTION 6.01, to enforce
its respective rights and interests in and under the Purchased Receivables, the
Related Security related thereto and the related Collections. The Servicer will
at all times apply the same standards and follow the same procedures with
respect to the decision to commence, and in prosecuting and litigating with
respect to Purchased Receivables as it applies and follows with respect to
accounts, chattel paper and instruments which are not Purchased Receivables. In
no event shall the Servicer be entitled to make the Collateral Agent, Triple-A
or the Administrative Agent a party to any litigation without the Collateral
Agent's, Triple-A's and the Administrative Agent's express prior written
consent. The Servicer shall segregate and set aside for the account of Triple-A
all Collections of the Purchased Receivables and Related Security in accordance
with SECTION 2.05 of the Purchase Agreement and SECTION 6.06 hereof and shall
cause all such Collections to be remitted to a Lock-Box Account and/or deposited
directly into the Collection Account within one Business Day after
identification thereof by the Servicer and in any event within four Business
Days after the Servicer's receipt thereof. The Servicer shall promptly review
all checks and other instruments returned to it by the Lock-Box Bank on account
of restrictive endorsements, improper payees, incorrect amounts or for any other
reason and shall not deposit any such checks or instruments in


                                       27

<PAGE>   32

its own accounts unless it is determined to the Collateral Agent's satisfaction
that such amounts do not constitute Collections; any such checks or instruments
which are determined to be Collections of the Purchased Receivables or Related
Security related thereto shall be promptly remitted to the Lock-Box Account or
the Collection Account as provided above. Provided that the Termination Date
shall not have occurred, the Originator, while it is Servicer, may, in
accordance with the Credit and Collection Policy, (i) amend, modify or waive any
term or condition of any Contract to reflect any Permitted Extension, (ii)
adjust the Outstanding Balance of any Purchased Receivable to reflect the
reductions, adjustments or cancellations described in the first sentence of
SECTION 2.04(d) of this Triple-A Purchase Agreement, (iii) so long as such
prepayment would not cause a Wind-Down Event under this Triple-A Purchase
Agreement or a "Wind-Down Event" under the Credit Agreement, and subject to the
payment of the Termination Amount, consent to the prepayment or early
termination of a Contract, and (iv) amend, modify or waive any provision of a
Delinquent Receivable or Defaulted Receivable so as to maximize the
collectibility thereof. The Servicer shall hold in trust for the Seller and
Triple-A in accordance with their respective interests, all Records.
Notwithstanding anything to the contrary contained herein, following the
occurrence of an Event of Termination, the Collateral Agent shall have the
absolute and unlimited right to direct the Servicer (whether the Servicer is the
Originator or otherwise) to commence or settle any legal action to enforce
collection of any Receivable or other Transferred Asset or to foreclose upon or
repossess any Related Security.

          (b)  The Servicer shall, as soon as practicable following receipt,
turn over (i) to the "Collateral Agent" under the Credit Agreement the
collections of any Transferred Asset which is not a Purchased Asset, and (ii) to
the Originator the collections of any receivable which is not a Transferred
Asset, in either case less, in the event the Originator is not the Servicer, all
reasonable and appropriate out-of-pocket costs and expenses of such Servicer of
servicing, collecting and administering such receivable.

          (c)  Notwithstanding anything to the contrary contained in this
Agreement, the Servicer, if the Collateral Agent or its designee, shall have no
obligation to collect, enforce or take any other action described in this
ARTICLE VI with respect to any receivable that is not a Purchased Receivable
other than to deliver to the Seller the Collections and documents with respect
to any such receivable as described in the first two sentences of SECTION
6.02(b) and to exercise the same degree of care with respect to Collections and
documents in its possession as it would exercise with respect to its own
property.

          (d)  In the event the Servicer accepts in payment of any Purchased
Receivable the taking of repossession of the Equipment the sale or lease of
which gave rise to such Purchased Receivable, the Servicer agrees to use its
reasonable efforts to resell or re-lease such Equipment for the account of
Triple-A and shall remit to the Collateral Agent the gross sale proceeds thereof
or, to the extent such Equipment is re-leased, shall deliver to the Collateral
Agent the chattel paper or other documents evidencing the rights to payment
arising from such re-lease, all of which documents shall constitute Contracts
and which rights to payment shall constitute Purchased Receivables, and all of
which Contracts and Purchased Receivables shall constitute part of the Purchased
Assets. Neither Triple-A nor the Collateral Agent shall have any obligation to
take any action or commence any proceedings to realize upon any Purchased


                                       28

<PAGE>   33


Receivable or to enforce any of its rights or remedies with respect thereto. Any
moneys collected by the Servicer pursuant to this SUBSECTION 6.02(D) shall be
segregated by the Servicer, held in trust by the Servicer for Triple-A and shall
be remitted to a Lock-Box Account or to the Collection Account within one
Business Day after identification thereof by the Servicer and in any event
within four Business Days after the Servicer's receipt thereof.

          (e)  The Servicer shall maintain all books of account and other
records pertaining to the Purchased Receivables and the other Purchased Assets
in such form as will enable Triple-A or its designees to determine at any time
the status thereof. The Servicer will permit Triple-A, the Collateral Agent and
any Person designated by Triple-A or the Collateral Agent, during regular
business hours, to inspect, audit, check and make abstracts from all books,
accounts, records, or other papers pertaining to such Purchased Assets. From
time to time, at the request of Triple-A or the Collateral Agent, the Servicer,
at its own expense, will (i) deliver to Triple-A and the Collateral Agent and
any Person designated by Triple-A or the Collateral Agent any records and
invoices pertaining to the Purchased Assets and evidence thereof as Triple-A,
the Collateral Agent or such designee may deem necessary to enable it to enforce
its rights thereunder and (ii) mark each computer record relating to, and each
invoice or other evidence of, the Purchased Assets (whether or not such computer
record or other item is the property of Triple-A) as Triple-A or the Collateral
Agent may direct to reflect the interests of Triple-A and the Collateral Agent
in such Purchased Assets. The Servicer will either (i) segregate, from all the
documents relating to other receivables then owned or being serviced by the
Servicer, all documents relating to the Purchased Assets or (ii) mark all such
documents relating to the Purchased Assets so as to make such documents readily
identifiable as property of Triple-A and with such legend as shall be specified
by the Collateral Agent, and will, in either such event, hold all such documents
in trust for Triple-A and safely keep such documents in filing cabinets or other
suitable containers marked to show Triple-A's interest.

          SECTION 6.03. RIGHTS OF THE COLLATERAL AGENT. At any time:

          (a)  The Collateral Agent may notify the Obligors of the Purchased
     Receivables, or any of them, of Triple-A's ownership interest in the
     Purchased Assets and direct such Obligors, or any of them, that payment of
     all amounts payable under any Purchased Receivable be made directly to
     Triple-A or its designee (including, without limitation, the Collateral
     Agent).

          (b)  The Seller shall, at the Collateral Agent's or Triple-A's request
     and at the Seller's expense, give notice of Triple-A's interest in the
     Purchased Assets to each Obligor (in substantially the form of the Notice
     of Assignment) and direct that payments be made directly to Triple-A or its
     designee (including, without limitation, the Collateral Agent).

          (c)  The Seller shall, at the Collateral Agent's request, assemble all
     Records which the Collateral Agent reasonably believes are necessary or
     appropriate for the administration and enforcement of the Purchased Assets,
     and


                                       29

<PAGE>   34


     shall make the same available to the Collateral Agent at a place selected
     by the Collateral Agent or its designee.

          (d)  Each of the Seller and Triple-A hereby authorize the Collateral
     Agent to take any and all steps in the Seller's name and on behalf of the
     Seller necessary or desirable, in the determination of the Collateral
     Agent, to collect all amounts due under any and all Purchased Receivables
     or Related Security related thereto, including, without limitation,
     endorsing the Seller's name on checks and other instruments representing
     Collections and enforcing such Purchased Receivables and the related
     Contracts.

          SECTION 6.04. FURTHER ACTION EVIDENCING TRANSFERS. (a) The Seller
agrees that from time to time, at its expense, it will promptly execute and
deliver all further instruments and documents, and take all further action that
Triple-A may reasonably request in order to protect or more fully evidence
Triple-A's ownership interest in the Purchased Receivables, the Related Security
and the Collections related thereto, or to enable Triple-A to exercise or
enforce any of its rights hereunder or under any related document. Without
limiting the generality of the foregoing, the Seller will mark its master data
processing records evidencing such Purchased Receivables, Related Security and
Collections related thereto with a legend, acceptable to Triple-A, evidencing
that Triple-A has acquired an ownership interest therein as provided in this
Agreement and, upon the request of Triple-A, will execute and file such
financing or continuation statements, or amendments thereto or assignments
thereof, and such other instruments or notices, as may be necessary or
appropriate or as Triple-A may reasonably request. The Seller hereby authorizes
Triple-A to file one or more financing or continuation statements, and
amendments thereto and assignments thereof, relative to all or any of the
Purchased Receivables, Related Security and Collections related thereto now
existing or hereafter arising without the signature of the Seller where
permitted by law. A carbon, photographic or other reproduction of this Agreement
or any financing statement covering the Purchased Receivables, Related Security
and Collections related thereto, or any part thereof, shall be sufficient as a
financing statement. If the Seller fails to perform any of its agreements or
obligations under this Agreement, Triple-A may (but shall not be required to)
itself perform, or cause performance of, such agreement or obligation, and the
expenses of Triple-A incurred in connection therewith shall be payable by the
Seller upon Triple-A's demand therefor; PROVIDED, HOWEVER, prior to taking any
such action, Triple-A shall give notice of such intention to the Seller and
provide the Seller with a reasonable opportunity to take such action itself.

          (b)  The Seller shall, on or prior to the date of each Receivables
Purchase hereunder, deliver or cause to be delivered the related Contract File
to the Custodian, in suitable form for transfer by delivery, or accompanied by
duly executed instruments of transfer or assignment in blank, all in form and
substance satisfactory to Triple-A. In the event that the Seller or the Servicer
receives any other instrument or any writing constituting chattel paper which,
in either event, evidences a Purchased Receivable or other Purchased Assets, the
Seller or the Servicer as applicable shall deliver such instrument or chattel
paper to the Custodian on behalf of Triple-A within three (3) Business Days
after receipt, in suitable form for transfer by


                                       30

<PAGE>   35


delivery, or accompanied by duly executed instruments of transfer or assignment
in blank, all in form and substance satisfactory to Triple-A.

          SECTION 6.05. RESPONSIBILITIES OF THE SELLER. Anything herein to the
contrary notwithstanding, the Seller shall (i) perform all of its obligations
under the Contracts to the same extent as if such Contracts had not been
transferred to Triple-A hereunder and the exercise by Triple-A or its assigns of
their respective rights hereunder shall not relieve Seller from such obligations
and (ii) pay when due any taxes, including without limitation, sales, excise and
personal property taxes payable in connection with the Purchased Assets, unless
the Seller is contesting the payment of such taxes in good faith and by
appropriate proceedings and with respect to which no Adverse Claim has been
asserted or filed.

          SECTION 6.06. ADMINISTRATION OF COLLECTIONS BY SERVICER. (a) The
Servicer shall identify on a timely basis all Collections which are on account
of the Purchased Assets, including all deposits to Lock Box Accounts. On each
Business Day, all Collections received in the Lock Box Accounts for the prior
Business Day (and such Business Day, if practicable) shall be transferred to the
Collection Account. If the Servicer receives any cash or checks, drafts, wire
transfers or other instruments for the payment of money on account or otherwise
in respect of the Purchased Assets, the Servicer shall segregate such cash and
other items, hold such cash and other items in trust for the benefit of Triple-A
and the Collateral Agent and shall cause such cash and other items (properly
endorsed, where required, so that such items may be collected by Triple-A) to be
deposited in a Lock Box Account or directly in the Collection Account
immediately after the date any such cash or other item shall have been
identified as being on account of a Purchased Assets.

          SECTION 6.07. APPLICATION OF COLLECTIONS. All Collections on account
of the Purchased Receivables of each Obligor shall be applied in the order of
maturity thereof unless specifically identified otherwise in writing by such
Obligor or directed by a court of competent jurisdiction. Any payment by an
Obligor in respect of any indebtedness or other obligations owed by such Obligor
to the Seller or the Servicer shall, except as otherwise specified by such
Obligor or otherwise required by law, be applied as a Collection of a Receivable
of such Obligor (in the order of the age by invoice date of such Receivables,
starting with the oldest such Receivable) to the extent of any amounts then due
and payable thereunder before being applied to any other indebtedness of such
Obligor to the Seller or the Servicer. The Servicer shall not influence or
instruct any Obligor who is indebted to the Seller in respect of any
indebtedness not included in the Purchased Assets to direct that its remittances
be applied to any such indebtedness prior to being applied to the Purchased
Assets.

          SECTION 6.08. SERVICING FEE. On each Settlement Date, as full
compensation for its servicing activities hereunder, the Servicer shall be
entitled to receive a fee (the "SERVICING FEE") in an amount equal to 1.0% TIMES
the Outstanding Balance of the Purchased Receivables as of the last day of the
prior calendar month TIMES a fraction, the numerator of which is the number of
actual days elapsed in such calendar month and the denominator of which equals
360, PROVIDED, THAT, if the Servicer hereunder is also the Servicer under the
Purchase Agreement, the Servicing Fee hereunder shall be deemed paid to the
extent of any payment by the Seller of the


                                       31

<PAGE>   36


"Servicing Fee" specified and defined in the Purchase Agreement. Notwithstanding
the foregoing, to the extent that Advances under the Liquidity Agreement are
used to fund or maintain Borrowings or Purchases, then the Servicing Fee shall
be .75% TIMES the Outstanding Balance of the Receivables as of the last day of
the prior calendar month TIMES a fraction, the numerator of which is the number
of actual days elapsed in such calendar month and the denominator of which
equals 360. In the event that Triple-A (or the Collateral Agent) appoints a
successor Servicer, the Servicing Fee may be adjusted as required by such
successor Servicer and as agreed to by Triple-A and the Collateral Agent.

          SECTION 6.09. RESIGNATION; SUCCESSOR SERVICER. (a) The obligation of
the Servicer to service the Purchased Receivables is personal to the Servicer
and the parties recognize that another Person may not be qualified to perform
such obligations. Accordingly, the Servicer's obligation to service the
Purchased Assets hereunder shall be specifically enforceable and shall be
absolute and unconditional in all circumstances, including, without limitation,
after the occurrence and during the continuation of any Event of Termination or
Servicing Termination Event hereunder; PROVIDED, HOWEVER, that a Successor
Servicer may be appointed pursuant to this SECTION 6.09.

          (b)  Notwithstanding the foregoing, the Servicer may resign from the
obligations and duties hereby imposed on it as Servicer upon determination that
(i) the performance of its duties hereunder is no longer permissible under any
applicable law and (ii) there is no reasonable action which the Servicer could
take to make the performance of its duties hereunder permissible under any such
applicable law. Any determination permitting the resignation of the Servicer
shall be evidenced as to clause (i) above by an opinion of counsel to such
effect delivered to Triple-A and the Collateral Agent. Except to the extent
inconsistent with any such applicable law, no such resignation shall become
effective until a Successor Servicer shall have assumed the responsibilities and
obligations of the Servicer in accordance with the remaining provisions of this
SECTION 6.09.

          (c)  The Collateral Agent shall, as promptly as possible after the
Servicer has given notice pursuant to SECTION 6.09(b) above or at any time after
the Collateral Agent's designation of a successor Servicer pursuant to SECTION
6.01, appoint a successor servicer (the "SUCCESSOR SERVICER") and such Successor
Servicer shall accept its appointment by a written assumption in a form
acceptable to the Collateral Agent. Upon its appointment, the Successor Servicer
shall be the successor in all respects to the Servicer with respect to servicing
functions under this Agreement shall be subject to all the responsibilities,
duties and liabilities relating thereto placed on the Servicer by the terms and
provisions hereof, and all references in this Agreement or any other Facility
Documents to the Servicer shall be deemed to refer to the Successor Servicer.
The Servicer agrees to cooperate with the Successor Servicer in effecting the
transfer of its responsibilities, duties, liabilities and rights hereunder,
including, without limitation, the execution and delivery of assignments of
financing statements, the transfer to the Successor Servicer of all cash amounts
held by the Servicer or thereafter received with respect to the Purchased
Assets, the transfer of electronic records relating to the Purchased Assets in
such form as the Successor Servicer may reasonably request and the transfer of
all related Records, correspondence and other documents relating to the
Purchased Assets.

          SECTION 6.10. LOCK-BOX ACCOUNTS; COLLECTION ACCOUNT. The Seller has
established and will maintain a system of operations, accounts and instructions
to the Lock-Box Banks and will establish and maintain the Collection Account as
provided in this SECTION 6.10. Pursuant to a Lock-Box Agreement, each Lock-Box
Account shall be irrevocably instructed to wire all funds to the Collection
Account, which Collection Account shall be maintained in the name of the
Collateral Agent. Neither the Seller, nor any Person claiming by, through or
under the Seller shall have any control over the use of, or any right to
withdraw any item or amount from, any Lock-Box Account or the Collection Account
except as expressly provided in the Lock-Box Agreements. The Collateral Agent on
behalf of Triple-A is hereby irrevocably authorized and empowered, as the
Seller's attorney-in-fact, to endorse any item deposited in a lock-box or
presented for deposit in any Lock-Box Account or the Collection Account
requiring the endorsement of the Seller, which authorization is coupled with an
interest.

          SECTION 6.11. COLLECTION ACCOUNT. (a) Pursuant to the Credit
Agreement, the Seller has established for the sole and exclusive benefit of the
Collateral Agent for the benefit of Triple-A, the Surety and their respective
assigns, a cash collateral account (the "COLLECTION ACCOUNT"). The Collection
Account shall be a special purpose segregated trust account maintained with Bank
of Boston but shall be under the sole dominion and control of, and in the name
of, the Collateral Agent. All funds held in the Collection Account, including
investment earnings thereon, shall be invested in Permitted Investments at the
direction of the Seller; PROVIDED, HOWEVER, that from and after the Termination
Date or otherwise upon the occurrence and during the continuance of any Event of
Termination, the Collateral Agent shall have the sole right to restrict the
maturities of any investments held in the Collection Account and to direct the
withdrawal of any such investments for the purposes of paying Capital, Yield and
any Obligations owed hereunder. The Collateral Agent shall have the sole and
exclusive right to withdraw or order a transfer of funds from the Collection
Account in accordance with the terms and provisions of this SECTION 6.11;
PROVIDED however, that the Collateral Agent agrees to turn over to the
Originator any funds which are deposited in the Collection Account and which do
not constitute Collections or other proceeds of Purchased Assets, less all
reasonable and appropriate out-of-pocket costs and expenses incurred by the
Collateral Agent in connection with such misdirected funds.

          (b)  All Collections and other proceeds of the Purchased Assets in the
Collection Account shall be held in trust for the benefit of Triple-A and the
Surety and, except as otherwise provided in SECTION 6.11(d) below with respect
to any Business Day from and after the Designated Termination Date, such
Collections and other proceeds shall be used solely for the following purposes
and in the following order of priority:

          (i)  To remit to the Seller any Collections representing sales or
     other taxes or insurance payments for the purpose of satisfying the
     Seller's obligations in respect of such taxes or insurance;

          (ii) To pay Yield and other Carrying Costs which are then due and
     payable;

          (iii) To repay Capital as provided in SECTION 2.04;


                                       33

<PAGE>   38


          (iv) To pay any other Obligations which may be due and owing at such
     time; and

          (v)  If such day is a Settlement Date, to be remitted to the Seller in
     consideration of the Deferred Purchase Price, PROVIDED, THAT if any
     "Obligations" under the Credit Agreement remain outstanding, such amounts
     shall be remitted to the Collateral Agent for application in accordance
     with the terms of the Credit Agreement to the extent of such Obligations;
     PROVIDED, further, that such funds shall only be remitted to the Seller to
     the extent that, after giving effect to such transfer of funds and such
     Purchases, the amount of Capital then outstanding does not exceed the
     Capital Limit then in effect.

The Seller, in making any request for funds to be withdrawn from the Collection
Account, shall certify to each of the Collateral Agent and the Collection
Account Bank that the funds will be used for one of the purposes described above
in this SECTION 6.11(b).

          If, on any Business Day prior to the Designated Termination Date, the
Collections of Purchased Assets on deposit in the Collection Account and
available for withdrawal under CLAUSE (II) above are less than the amount of the
obligations described in such CLAUSE, such available funds shall be allocated in
the priority set forth in SECTION 6.11(c) below; if, on any such Business Day,
the Collections of Purchased Assets on deposit in the Collection Account and
available for withdrawal under CLAUSE (IV) above are less than the amount of the
obligations described in such CLAUSE, such available funds shall be allocated to
the Persons to whom such obligations are owed ratably according to the
respective amounts owed.

          (c)  On each Business Day prior to the Designated Termination Date, to
the extent that the Collections of Purchased Assets on deposit in the Collection
Account and available under CLAUSE (II) of SECTION 6.11(b) are insufficient to
pay all Carrying Costs which are then due and payable, such funds shall be
applied to the Carrying Costs in the following order of priority:

          (i) To pay any accrued and unpaid Yield (either directly, by paying to
     the Swap Provider amounts owed under the Interest Rate Hedges or by
     reimbursing Triple-A and/or the Surety for payments made by either of them
     to the Swap Provider on account of amounts owed under the Interest Rate
     Hedges);

          (ii) To pay the pro-rata portion of any accrued and unpaid fees owing
     under the Fee Letter which are allocable to this Agreement;

          (iii) To pay the pro-rata portion of any accrued and unpaid expenses
     of the Collateral Agent which are allocable to this Agreement;

          (iv) To pay any accrued and unpaid Servicing Fee; and

          (v) To pay ordinary course expenses of the Seller to the extent the
     same are due or past due.


                                       34

<PAGE>   39


If, on any such Business Day, the Collections of Purchased Assets on deposit in
the Collection Account and available for withdrawal under either CLAUSE (II) or
(V) above are less than the amount of the obligations described in such CLAUSE,
such available funds shall be allocated to the Persons to whom such obligations
are owed ratably according to the respective amounts owed.

          (d)  On each Business Day from and after the Designated Termination
Date, Collections and other proceeds of Purchased Assets shall be withdrawn from
the Collection Account solely upon direction of the Collateral Agent to be
applied against the Obligations in the following order of priority;

          (i) To remit to the Seller any Collections representing sales or other
     taxes or insurance payments for the purpose of satisfying the Seller's
     obligations in respect of such taxes or insurance;

          (ii) To pay any accrued and unpaid Servicing Fee (if the Servicer is a
     party other than the Originator or an Affiliate thereof);

          (iii) To pay accrued and unpaid Yield (either directly or by paying to
     the Swap Provider amounts owed under the Interest Rate Hedges or by
     reimbursing Triple-A and/or the Surety for payments made by either of them
     to the Swap Provider on account of amounts owed under the Interest Rate
     Hedges);

          (iv) To pay the pro-rata portion of any accrued and unpaid fees owing
     under the Fee Letter which are allocable to this Agreement;

          (v) To repay all outstanding Capital;

          (vi) To pay the pro-rata portion of the accrued and unpaid expenses of
     the Collateral Agent which are allocable to this Agreement;

          (vii) To pay any other accrued and unpaid Obligations which have not
     been paid pursuant to clauses (i) through (v) above;

          (viii) To pay any other Carrying Costs which are due and owing but
     have not been paid pursuant to clauses (i) through (vi) above; and

          (ix) To pay any accrued and unpaid Servicing Fee owed to the
     Originator or an Affiliate thereof.

If, on any such Business Day, the funds on deposit in the Collection Account and
available for withdrawal under either CLAUSE (iv), (vi), (vii) or (viii) above
are less than the amount of the obligations described in such CLAUSE, such
available funds shall be allocated to the Persons to whom such obligations are
owed ratably according to the respective amounts owed. Any funds remaining in
the Collection Account after payment of the foregoing Obligations and other fees
and expenses shall be remitted to the Seller in consideration of the Deferred
Purchase Price, PROVIDED that if any "Obligations" under the Credit Agreement
remain outstanding, such funds


                                       35

<PAGE>   40


shall be remitted to the Collateral Agent for application in accordance with the
terms of the Credit Agreement to the extent of such "Obligations".

                                   ARTICLE VII

                           WIND-DOWN EVENTS; REMEDIES

          SECTION 7.01. WIND-DOWN EVENTS. Each of the following events shall
constitute a "WIND-DOWN EVENT" within the meaning of this Triple-A Purchase
Agreement:

          (a)  The occurrence of any Event of Termination under the Purchase
Agreement or any "Wind-Down Event" under the Credit Agreement;

          (b)  The Servicer (if the Seller or any Affiliate of the Seller) shall
fail to perform or observe any term, covenant or agreement hereunder (other than
as referred to in clause (ii) of this SECTION 7.01(b)) and such failure shall
remain unremedied for three Business Days after written notice from the
Collateral Agent or (ii) either the Servicer (if the Seller or any Affiliate of
the Seller) or the Seller shall fail to make any payment or deposit to be made
by it hereunder when due and, solely in the case of any such payments which do
not constitute payments of Capital or Yield, such failure shall remain
unremedied for three (3) Business Days after written notice from the Collateral
Agent; or

          (c)  The Seller shall fail to perform or observe any term, covenant or
agreement contained in SECTION 5.03 and any such failure shall remain unremedied
for five (5) Business Days after written notice from the Collateral Agent; or

          (d)  Any representation or warranty made or deemed to be made by the
Seller (or any of its officers) under or in connection with this Triple-A
Purchase Agreement, any Settlement Report or other information or report
delivered pursuant hereto shall prove to have been false or incorrect in any
material respect when made; PROVIDED, HOWEVER, that (i) to the extent any breach
of any such representation or warranty may be cured within ten (10) Business
Days, the Seller shall have ten (10) Business Days after learning of such breach
to make such representation and warranty true and correct and (ii) if any such
false or incorrect representation or warranty has given rise to a deemed
Collection as provided under SECTION 2.04 of this Triple-A Purchase Agreement,
then, upon the Seller's payment of such deemed Collection at the time and in the
manner required under this Triple-A Purchase Agreement, the breach of such
representation or warranty shall not give rise to a Wind-Down Event under this
subsection (d); or;

          (e)  The Seller shall fail to perform or observe any other term,
covenant or agreement contained in this Triple-A Purchase Agreement on its part
to be performed or observed and any such failure shall remain unremedied for ten
(10) Business Days after written notice from the Collateral Agent (it being
understood that if any such failure gives rise to a deemed Collection under
SECTION 2.04 of this Triple-A Purchase Agreement, then, the payment of such
deemed Collection at the time and in the manner required under this Triple-A
Purchase Agreement shall be deemed a remedy of such failure); or


                                       36

<PAGE>   41


          (f)  The interest of the Collateral Agent in the Purchased Assets
shall for any reason, except to the extent permitted by the terms hereof, cease
to create a valid and perfected first priority interest in such Purchased
Assets; PROVIDED, HOWEVER, if any such failure results in a deemed Collection
under SECTION 2.04 of this Triple-A Purchase Agreement and the Seller satisfies
in full its payment obligations under such section with respect to such deemed
Collection, then such failure shall not give rise to a Wind-Down Event under
this subsection (f); or

          (g)  (i) An Insolvency Event shall occur with respect to the Seller or
the Originator or (ii) the Seller or the Originator shall take any corporate
action to authorize the filing of any Insolvency Proceeding; or

          (h)  As of the close of business on any Settlement Date, the Capital
Limit shall be less than the aggregate outstanding Capital; or

          (i)  The Originator shall cease to own 100% of the issued and
outstanding stock of the Seller; or

          (j)  There shall have occurred, since the initial Receivables Purchase
Date, a material adverse change in the financial condition of the Seller or
there shall have occurred any event which materially and adversely affects the
collectibility or the Receivables generally or the ability of the Seller to
perform hereunder; or

          (k)  Triple-A or the Surety shall determine that continuation of this
Triple-A Purchase Agreement without exercise of remedies under Section 7.02 will
impose a material adverse regulatory impact on Triple-A or the Surety, as the
case may be.

          SECTION 7.02. REMEDIES. During the existence of a Wind-Down Event, the
Collateral Agent on behalf of Triple-A may, by written notice to the Seller,
take any or all of the following actions, at the same or different times: (i)
declare the Termination Date to have occurred; (ii) declare the Obligations to
be immediately due and payable; (iii) pursue any other remedy under this
Triple-A Purchase Agreement and the other Facility Documents and (iv) exercise
any rights and remedies of a secured party under Article 9 of the UCC, which
rights and remedies shall be cumulative to those provided for under this
Triple-A Purchase Agreement and the other Facility Documents; PROVIDED, HOWEVER,
that in the case of any event described in clause (i) of SUBSECTION 7.01(g)
above, then, automatically upon the occurrence of such event without
presentment, demand, protest or other notice of any kind, all of which are
hereby expressly waived by the Seller, anything contained herein to the contrary
notwithstanding, the Termination Date shall be deemed to have occurred
automatically and any Obligations owed hereunder shall be immediately due and
payable. The rights and remedies of a secured party which may be exercised by
the Collateral Agent pursuant to clause (iv) of this SECTION 7.02 shall include,
without limitation, the right to (y) identify and engage a Successor Servicer to
act as servicer for the Receivables in the event of a Servicing Termination
Event, and (z) without notice except as specified below solicit and accept bids
for and sell the Purchased Assets or any part thereof in one or more parcels at
a public or private sale, at any exchange, broker's board or at any of the
Collateral Agent's offices or elsewhere, for cash, on credit or for future
delivery, and


                                       37
<PAGE>   42


upon such other terms as the Collateral Agent may deem commercially reasonable.
The Seller agrees that, to the extent notice of sale shall be required by law,
10 Business Days' notice to the Seller of the time and place of any public sale
or the time after which any private sale is to be made shall constitute
reasonable notification and that it shall be commercially reasonable for the
Collateral Agent to sell the Purchased Assets on an as-is basis, without
representation or warranty of any kind. The Collateral Agent shall not be
obligated to make any sale of Purchased Assets regardless of notice of sale
having been given and may adjourn any public or private sale from time to time
by announcement at the time and place fixed therefor, and such sale may, without
further notice, be made at the time and place to which it was so adjourned.

                                  ARTICLE VIII

Surety) and their respective officers, directors, agents and employees (each, an
"INDEMNIFIED PARTY"), from and against any and all damages, losses, claims,

     Seller or the Originator pursuant hereto, which shall have been false or
     incorrect in any material respect when made or deemed made or delivered;

          (iii) the failure by the Seller or the Originator (individually or as
     Servicer) to comply with any term, provision or covenant contained in this
     Triple-A Purchase Agreement or the Purchase Agreement (other than any
     covenant contained in SECTION 5.04 of the Purchase Agreement, a breach of
     which shall constitute an Event of Termination but shall not give rise to
     indemnification under this SECTION 8.01), or any agreement executed in
     connection with this Triple-A Purchase Agreement or the Purchase Agreement
     or with any applicable law, rule or regulation with respect to any
     Purchased Receivable, the related Contract, the Related Security or the

     any Contract or Receivables which are, or are purported to be, Purchased
     Assets, whether at the time of any Purchase or at any subsequent time;

          (vi) any dispute, claim, offset or defense (other than discharge in
     bankruptcy of the Obligor) of the Obligor to the payment of any Purchased
     Receivable (including, without limitation, a defense based on such
     Purchased Receivable or the related Contract not being a legal, valid and
     binding obligation of such Obligor enforceable against it in accordance
     with its terms), or any other claim resulting from the sale or lease of the
     Equipment and/or services related thereto or the furnishing or failure to
     furnish such Equipment and/or services;

          (vii) any failure of the Seller or the Originator, as Servicer or

     equitable cause, statute, regulation, judicial proceeding or other
     applicable laws (including, without limitation, Section 365 of the
     Bankruptcy Code);

          (xi) the failure of the Seller, the Originator and the Obligors under

Days following the Indemnified Party's demand therefor.

          SECTION 8.02. REPURCHASES OF DESIGNATED RECEIVABLES. The following
rights are in addition to and not in limitation of any other rights or remedies
that Triple-A or CapMAC may have hereunder.

          (a)  The Seller may, at any time upon not less than five Business
Days' prior written notice to the Collateral Agent, elect to repurchase any
Designated Receivable and the Purchased Assets relating thereto, which purchase
shall take place on the first Settlement Date to occur after the Collateral
Agent's receipt of such notice, for the repurchase price specified in SUBSECTION
(b) of this SECTION 8.02.

          (b)  In the case of a repurchase from Triple-A by the Seller of a
Purchased Asset pursuant to this SECTION 8.02, the Seller shall, on the
Settlement Date coinciding with such repurchase pay to the Collateral Agent as a
reduction of Capital an amount equal to the Outstanding Balance of the related
Designated Receivable. The proceeds of any such repurchase shall be deemed to be
Collections of such Purchased Asset received by the Seller, and the amount of
each such Collection shall be applied as provided in SECTION 2.04. The
repurchase of any Purchased Asset shall not relieve the Seller of its obligation
under SECTION 2.04(a) to pay Yield on the Capital outstanding with respect to
such Purchased Asset through the Payment Date relating to such Capital. Any such
repurchase shall be made without recourse or warranty, express or implied (other
than a representation and warranty that such Asset is free and clear of any

final and complete integration of all prior expressions by the parties hereto
with respect to the subject matter hereof and shall constitute the entire

or the exercise of any other right. The remedies herein provided are cumulative
and not exclusive of any remedies provided by law.

          SECTION 9.04. BINDING EFFECT; ASSIGNABILITY. This Triple-A Purchase

PROVIDED, HOWEVER, that the rights and remedies with respect to any breach of
any representation and warranty made by the Seller pursuant to Article IV and

Triple-A Purchase Agreement.

          SECTION 9.05. GOVERNING LAW; WAIVER OF JURY TRIAL. THIS TRIPLE-A
PURCHASE AGREEMENT SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE
LAWS OF THE STATE OF NEW YORK, EXCEPT TO THE EXTENT THAT THE VALIDITY OR
PERFECTION OF THE INTERESTS OF THE COLLATERAL AGENT IN THE COLLATERAL OR

THE RELATIONSHIP BETWEEN THEM IN CONNECTION WITH THIS TRIPLE-A PURCHASE
AGREEMENT. INSTEAD, ANY DISPUTE RESOLVED IN COURT WILL BE RESOLVED IN A BENCH
TRIAL WITHOUT A JURY. WITH RESPECT TO THE FOREGOING CONSENT TO JURISDICTION, THE
SELLER HEREBY WAIVES ANY OBJECTION BASED ON FORUM NON CONVENIENS, AND ANY
OBJECTION TO VENUE OF ANY ACTION INSTITUTED HEREUNDER AND CONSENTS TO THE
GRANTING OF SUCH LEGAL OR EQUITABLE RELIEF AS IS DEEMED APPROPRIATE BY THE
COURT. NOTHING IN THIS SECTION 9.05 SHALL AFFECT THE RIGHT OF TRIPLE-A OR THE
COLLATERAL AGENT TO SERVE LEGAL PROCESS IN ANY OTHER MANNER PERMITTED BY LAW OR
AFFECT THE RIGHT OF TRIPLE-A OR THE COLLATERAL AGENT TO BRING ANY ACTION OR
PROCEEDING AGAINST THE SELLER OR ITS PROPERTY IN THE COURTS OF ANY OTHER
JURISDICTION.
