                         TERMS OF THE CONTRACT PURCHASES

     Section 2.1. Purchase and Sale of Contracts; Purchase Price.

          2.1(a) General Purchase Commitment. Subject to the terms and
     conditions of this Agreement, on such Purchase Date or Purchase Dates prior
     to the Contract Purchase Termination Date with respect to which one or both
     Sellers shall have given the Agent, on behalf of the Buyers, a timely
     Purchase Request pursuant to Section 2.2, the Related Seller will sell to
     the Buyers and the Buyers will severally purchase from the Related Seller
     undivided percentage ownership interests in all Eligible Contracts tendered
     by the Related Seller, together with all of the Related Seller's right,
     title and interest in and to any Related Security, any Related Security
     Documents and the proceeds of any of the foregoing; provided, however, that
     the Buyers will not be required to purchase any Contract that would cause:

               (a) the sum of (i) the aggregate principal amount outstanding
          under all Buyers' Contracts as of the relevant Purchase Date, plus
          (ii) the aggregate principal portion of all payments by Obligors under
          Buyers' Contracts that have not been remitted to the Agent for the
          benefit of the Buyers as of the relevant Purchase Date pursuant to
          Section 4.1(a),

     to exceed

               (b) the remainder of the Contract Purchase Commitment Amount,
          minus the aggregate unpaid principal amount of "Loans" then
          outstanding under the Credit Agreement,

     all determined as of the relevant Purchase Date; and

     provided further that the Buyers shall not be required to purchase any
     Contracts from a Seller unless the aggregate Purchase Price of the
     Contracts to be purchased from that Seller on that Purchase Date is
     $300,000 or more. Undivided percentage ownership interests in Eligible
     Contracts tendered by a Seller hereunder shall be purchased by the Buyers
     ratably in the proportion of their respective Individual Contract Purchase
     Commitment Amounts. The price to be paid by the Buyers to each Seller on
     each Purchase Date shall equal the


                                       15
<PAGE>

     aggregate Purchase Price of all Contracts tendered to the Buyers by that
     Seller and accepted by the Buyers on such Purchase Date. The sales of
     Contracts contemplated hereby shall be made pursuant to and in reliance
     upon the representations, warranties and agreements of the Sellers
     contained herein and in the documents delivered pursuant hereto, and shall
     be without recourse against the Sellers except as provided herein.

          2.1(b) New Buyers' Purchase of Interest in Existing Contracts. As of
     the Closing Date, the aggregate principal amount outstanding under all
     "Buyer's Contracts" (as defined in, and as previously purchased pursuant
     to, the Existing Purchase Agreement) (collectively, the "Existing Buyers'
     Contracts") is $74,275,858.21 and interest accrued under the Existing
     Buyers' Contracts at the Buyer's Rate is $0.00. On the Closing Date, Tokyo
     and Northern shall pay to the Agent, which shall in turn pay to each of the
     other Buyers, in Immediately Available Funds, the amount by which such
     other Buyer's share of such aggregate principal and interest amounts under
     the Existing Purchase Agreement exceeds its respective Buyer's Percentage
     of such aggregate principal and interest amounts. Effective upon receipt of
     such payments by U.S. Bank and M&I, each Buyer hereby sells, assigns and
     transfers, to the Agent for the benefit of the Buyers, its successors and
     assigns, all right, title and interest of such Buyer in, to and under (i)
     each Existing Buyers' Contract, (ii) all Related Security for such
     Contracts, (iii) all Related Security Documents, (iv) all rights against
     the Sellers with respect to any of the foregoing, and (v) all proceeds of
     any of the foregoing. Each of the several Buyers shall thereafter own an
     undivided percentage ownership interest in the Existing Buyers' Contracts
     in the amount of that Buyer's respective Buyer's Percentage thereof. Except
     as provided in the next sentence, THE FOREGOING ASSIGNMENT IS WITHOUT
     REPRESENTATION OR WARRANTY BY, OR RECOURSE TO, ANY BUYER. Each Buyer does
     represent and warrant that it has the requisite power and authority to make
     the foregoing assignment, and that the Existing Buyers' Contracts are free
     and clear of any Lien created by such Buyer. From and after the Closing
     Date, the Existing Buyers' Contracts shall be treated in every respect as
     though undivided percentage ownership interests therein had been purchased
     by the several Buyers from the Sellers hereunder, and shall be deemed to be
     Buyers' Contracts hereunder, and all representations and warranties made by
     the Sellers with respect thereto shall be deemed to have been made to and
     for the benefit of the Agent and the Buyers.

     Section 2.2. Procedures For Contract Purchases. Not less than five Business
Days before the date a Seller desires to sell Contracts to the Buyers hereunder,
that Seller shall deliver to the Agent a written request to buy Contracts in the
form of Exhibit D attached hereto or another form acceptable to the Majority
Buyers (a "Purchase Request"), setting forth (a) the proposed Purchase Date, (b)
the Contracts that Seller proposes to sell on such date, identified by the name
of the Obligor under, the principal amounts outstanding under, and the number of
months remaining until the final maturity date with respect to, each Contract,
and specifying which Contracts, if any, are Discounted Contracts and the
Seller's "book basis yield" with respect to each such Discounted Contract, and
(c) the Purchase Price for such


                                       16
<PAGE>

Contracts. The Agent shall promptly notify each other Buyer of the receipt of
such Purchase Request, the matters specified therein, and of such Buyer's
ratable share of the requested Purchase Price (which shall be that Buyer's
respective Buyer's Percentage thereof). The Agent and the Buyers shall have an
opportunity prior to each Purchase Date to inspect all documentation relating to
the Contracts tendered for sale and the Related Security as the Agent or the
Buyers shall request and shall in no event be obligated to purchase any Contract
that the Agent, in its reasonable discretion, determines is not an Eligible
Contract. On or before each Purchase Date:

          (i) the Related Seller shall deliver to the Agent an assignment in the
     form of Exhibit E hereto (including Schedule I thereto) (an "Assignment"),
     which will be effective to transfer to the Agent, for the benefit of the
     Buyers, as of such Purchase Date all of the Related Seller's right, title
     and interest in, to and under all Contracts tendered for purchase by that
     Related Seller and any Related Security and Related Security Documents (and
     such additional forms of assignment or conveyance concerning the Related
     Security and Related Security Documents as shall be necessary or
     appropriate, in the Agent's sole determination, to transfer of record the
     Related Seller's rights therein to the Buyer);

          (ii) the Related Seller shall deliver to the Agent the original
     executed Contracts tendered for purchase by that Related Seller; and

          (iii) the Related Seller shall place all records maintained by that
     Related Seller relating to such tendered Contracts in separate files with
     appropriate markings to indicate the Buyers' ownership thereof.

On each Purchase Date, each Buyer shall provide its Buyer's Percentage of the
requested Purchase Price to the Agent in Immediately Available Funds not later
than 3:00 p.m., Minneapolis time. Unless (i) the Agent determines that any
applicable condition specified in Article V has not been satisfied, or (ii) one
or more of the Buyers does not provide its Buyer's Percentage of the requested
Purchase Price in a timely fashion, the Agent will pay to each Seller, in
Immediately Available Funds, the Purchase Price of the Contracts (if any)
tendered by that Seller and accepted by the Buyers, such payment to be made at
the Agent's principal office in Minneapolis, Minnesota in immediately available
funds not later than 4:00 p.m. (Minneapolis time) on the requested Purchase
Date.

     Section 2.3. Optional Reduction of Contract Purchase Commitment Amount. The
Sellers may, at any time, upon not less than five Business Days prior written
notice to the Agent, executed by both Sellers, reduce the Contract Purchase
Commitment Amount, with any such reduction in a minimum amount of $1,000,000,
or, if more, in an integral multiple of $500,000; provided, however that the
Contract Purchase Commitment Amount may not be reduced to an amount less than
the principal amount outstanding under all Buyers' Contracts as of the date of
the reduction.


                                       17
<PAGE>

     Section 2.4. Commitment and Agent's Fee. If the Credit Agreement has been
terminated, or if the "Commitment" thereunder has been terminated or reduced,
the Sellers hereby jointly and severally agree to pay to the Buyers a commitment
fee (the "Commitment Fee") in an amount equal to the Applicable Commitment
Percentage per annum of the average daily Unused Contract Purchase Commitment
for the period from the date the Credit Agreement was terminated or the
"Commitment" thereunder was terminated or reduced to the Termination Date. Such
Commitment Fees are payable in arrears on each Quarterly Payment Date. The
Commitment Fees shall be computed on the basis of actual days elapsed and a year
of 360 days. If the Credit Agreement has been terminated, the Sellers hereby
jointly and severally agree to pay to the Agent on each anniversary of the
Closing Date, for the Agent's own account, a yearly agent's fee in the amount
provided in a fee letter of even date herewith from the Agent to PDC. No Buyer
(other than the Agent) shall be entitled to any portion of such fee.

     Section 2.5. Payments. Payments and prepayments of principal and interest
on the Contracts and all fees, expenses and other obligations under this
Agreement shall be made without setoff or counterclaim in Immediately Available
Funds (a) if to the Agent for the benefit of the Buyers or for its own account,
not later than 12:00 noon (Minneapolis time) on the dates called for under this
Agreement at its main office in Minneapolis, Minnesota, and (b) if to a Seller,
by deposit of the same into that Seller's operating account with the Agent not
later than 12:00 noon (Minneapolis time) on such date. Funds received after such
time shall be deemed to have been received on the next Business Day. Whenever
any payment to be made hereunder shall be stated to be due on a day which is not
a Business Day, such payment shall be made on the next succeeding Business Day
and such extension of time, in the case of a payment of principal, shall be
included in the computation of any interest on such principal payment. In the
event either Seller for any reason fails to pay or remit any amount or charge
due hereunder, such overdue amount shall bear interest from the due date thereof
until paid at the Reference Rate plus two percent (2%) per annum.

     Section 2.6. Security Interest. The Sellers and the Buyers intend that the
transactions contemplated hereby shall be treated as a purchase and sale of the
Contracts, Related Security, Related Security Documents and proceeds for all
purposes and not as a lending transaction. In the event the transactions
contemplated hereby are determined not to constitute purchases and sales despite
the intentions of the parties, (a) each Seller shall be deemed to have granted
to the Agent, for the benefit of the Buyers, and each Seller does hereby grant
to the Agent, for the benefit of the Buyers, a security interest in and to that
Seller's interest in each Contract identified in an Assignment or delivered to
the Agent, the Related Security, the Related Security Documents, any amounts in
the Holding Account, and all proceeds of all of the foregoing, to secure all of
that Seller's obligations under this Agreement, whether now existing or
hereafter created, the Servicer's obligations to remit proceeds of the Contracts
and make other payments to the Bank as provided in Article IV, that Seller's
obligations to repurchase the Contracts as provided in Article VII, and that


                                       18
<PAGE>

Seller's obligations under its Guaranty, and (b) the Financing Statements shall
perfect such security interest.

     Section 2.7 Continuation of Buyer's Rate. PDC may elect to fix the
Eurodollar Interbank Rate with respect to any portion of the outstanding
principal balance of the Buyers' Contracts (each such portion, a "Fixed Rate
Tranche") for a period of two, three, six or (if acceptable to all of the
Buyers, in their sole and absolute discretion) nine or twelve Interest Periods
(each a "Fixed Rate Period"), by giving the Agent notice, which may be by
telephone, given so as to be received by the Agent not later than 10:00 a.m.,
Minneapolis time, three Business Days prior to the first day of such Fixed Rate
Period (which must be a Settlement Date). No Fixed Rate Tranche may be elected
if, after giving effect thereto, the scheduled amortization of the Buyers'
Contracts would result in any portion of any Fixed Rate Tranche being repaid
before the end of the Fixed Rate Period applicable thereto. Fixed Rate Tranches
may only be elected in amounts of $500,000 or an integral multiple thereof. Each
such notice shall specify (i) the portion of the outstanding principal balance
of the Buyers' Contracts to be included in such Fixed Rate Tranche and (ii) the
number of Interest Periods to be included in such Fixed Rate Period. For all or
any portion of the outstanding principal balance of the Buyers' Contracts with
respect to which no election pursuant to this Section 2.7 is effective, the
Eurodollar Interbank Rate and the Eurodollar Rate (Reserve Adjusted) will be
determined for a single Interest Period. No election pursuant to this Section
2.7 may be made if a Termination Event or Unmatured Termination Event has
occurred and is continuing. No more than five Fixed Rate Tranches may be
outstanding at any one time.

     Section 2.8 Funding Losses; Fixed Rate Tranches. PDC shall compensate each
Buyer, upon its written request, for all losses, expenses and liabilities
(including any interest paid by such Buyer to lenders of funds borrowed by it to
make or carry Fixed Rate Tranches to the extent not recovered by such Buyer in
connection with the re-employment of such funds and including loss of
anticipated profits) which such Buyer may sustain if, for whatever reason, any
principal amount of a Fixed Rate Tranche is paid, or the rate payable thereon is
converted pursuant to Section 12.3, on any day prior to the last day of the
Fixed Rate Period applicable thereto. A Buyer's request for compensation shall
set forth the basis for the amount requested and shall be final, conclusive and
binding, absent error.

                            COLLECTIONS AND SERVICING

     Section 3.1. Servicing Agency. Until such time, if any, as the Agent shall
notify Seller in writing pursuant to Section 3.4 hereof of the revocation of
such power and authority, PDC shall, as agent for the Buyers, at PDC's expense,
and for the consideration described in Section 4.4, collect or cause to be
collected, for and on behalf of the Buyers, from the Obligors under all Buyers'
Contracts (whether purchased from PDC or PDSI), Related Security and Related
Security Documents, all amounts as and when due and owing thereunder. The
Servicer shall convert all checks and other instruments received on account


                                       19
<PAGE>

reasonable. All such immediately available funds collected by the Servicer shall
be deposited as promptly as practicable (not later than the Business Day after
the date such amounts are received) into the "Collection Account" (as defined in
the next sentence). The Collection Account shall be an escrow account in the
name of the Agent, for the benefit of the Buyers, at U.S. Bank Trust National
Association under that certain Escrow Agreement dated as of June 20, 1997
between PDC, PDSI, the Agent and U.S. Bank Trust National Association. On each
Settlement Date, the Servicer shall withdraw such portion of the funds in the
Collection Account as is necessary to make any payments due to the Buyers on
such Settlement Date, under Sections 4.1, 4.2 or any other section hereof, and
to pay PDC or itself the amount of any Positive Interest Differentials and any
accrued, unpaid earnings on the Collection Account pursuant to Section 4.6. At
any time after the occurrence of a Termination Event, the Agent may withdraw any
amounts in the Collection Account to pay any amounts due under Sections 4.1, 4.2
or any other section hereof at any time, without instructions from the Servicer.
Any amounts withdrawn by the Agent shall be applied first to amounts payable to
the Buyers under Sections 4.1 and 4.2, next to any other obligations owed to the
Buyers under this Agreement, and any surplus shall be paid pursuant to Section
4.6.

     Section 3.2. Standard of Care. The Servicer shall, as part of its
administrative and servicing obligations hereunder, be responsible for all
administration, servicing and collection of all Buyers' Contracts, Related
Security and Related Security Documents. In performing such functions, the
Servicer agrees to exercise the same degree of skill and care and apply the same
standards, policies and procedures that it applies to the performance of the
same functions with respect to Contracts, Related Security and Related Security
Documents and rights of recourse owned by it (or, if it no longer owns any
Contracts, in accordance with its practices when it did own Contracts).

     Section 3.3. Sellers' Obligations to Obligors. Anything herein to the
contrary notwithstanding, (a) the Related Seller shall remain liable under the
Contracts and the Related Security Documents to the extent set forth therein to
perform all of its duties and obligations thereunder to the same extent as if
this Agreement had not been executed and the Contracts had not been sold to the
Buyers, (b) the exercise by the Agent or any Buyer of any of the rights
hereunder shall not release the Related Seller from any of its duties or
obligations under the Contracts and the Related Security Documents, and (c) the
Agent and the Buyer shall have no obligation or liability under the Contracts
and the Related Security Documents by reason of this Agreement, nor shall the
Agent or the Buyer be obligated to perform any of the obligations or duties of
the Related Seller thereunder or to take any action to collect or enforce any
claim for payment assigned hereunder. The Related Seller will at all times
observe and perform, or cause to be observed and performed, all contractual
undertakings of the Related Seller to the Obligor under each Contract and the
Related Security Documents.

     Section 3.4. Termination of Servicing Agency. Notwithstanding the other
provisions of this Article III, if the Agent reasonably determines at any time,
in its sole discretion, that (i) the Servicer has failed to perform its
servicing and collection functions hereunder and has not corrected such failure
within ten (10) days of Agent's notifying the Servicer of such failure, (ii) a
Termination Event has occurred and is continuing, or (iii) there has been a
material adverse change in PDC's financial condition, the Agent may terminate
PDC's agency hereunder by delivering written notice of the Agent's revocation of
PDC's power and authority to service the Buyers' Contracts. After delivering
written notice pursuant to the preceding sentence, the Agent may directly
service the Buyers' Contracts and Related Security (or engage a third party to
do so on the Buyers' behalf). In such event, the Agent shall have the right,
without limitation, and notwithstanding Section 4.4 hereof, to collect and
retain all payments (excluding Positive Interest Differentials) received from
Obligors and shall be entitled to reimbursement (not to exceed the amounts from
time to time collected constituting Positive Interest Differentials and earnings
on the Collection Account) from PDC on demand for all reasonable expenses
incurred by the Agent (including but not limited to any fees and expenses of any
successor servicer and fees, service charges and disbursements of legal counsel)
in connection with such servicing activities (and the Agent may deduct such
expenses from collected amounts constituting Positive Interest Differentials and
earnings on the Collection Account) as provided in Section 4.6. Nothing
contained in this paragraph shall be construed to limit or otherwise affect or
modify PDC's obligation to make up interest deficiencies as provided in Section
4.2 and, if the Agent assumes servicing and collection functions under this
Article III, the Agent may from time to time deduct the amount of such
deficiencies from amounts constituting Positive Interest Differentials.

     Section 3.5. Notices of Assignment to Obligors. On or before the Purchase
Date with respect to each Contract sold to the Buyer by PDSI, PDSI shall notify
the Obligor that the Servicer is authorized to service such Contract on behalf
of PDSI. Each Seller shall join in giving to any Obligor such notice as the
Agent may reasonably request of the Buyers' purchase of Contracts under this
Agreement. The Agent may give such notice at any time, in its sole and unlimited
discretion.

     Section 3.6. Books and Records. The Servicer will keep and maintain at its
own cost and expense, satisfactory and complete records of the Buyers'
Contracts, the Related Security Documents and the Related Security, including a
record of all payments received and credits granted with respect to all
Contracts.

     Section 3.7. Insurance; Notice of Loss. The Servicer shall enforce the
provisions of the Buyers' Contracts requiring the Obligors to maintain insurance
as described in Section 8.27, in accordance with the standard of care required
by Section 3.2. Each Seller will promptly notify the Agent of any loss of or
material damage to any Contract, Related Security Document or Related Security
or of any substantial adverse change, known to that Seller, in any Contract or
material item of Related Security or the prospect of payment or performance
thereof.

                                   SETTLEMENTS

     Section 4.1. Payments to Buyers. On each Settlement Date, the Servicer will
remit to the Agent, for the benefit of the Buyers:

          (a) the full amount of all principal payments (including, without
     limitation, scheduled principal payments, prepayments of principal, overdue
     principal, and principal payable on acceleration) received by the Servicer
     under the Buyers' Contracts during the preceding Collection Period;

          (b) all payments of interest received by the Servicer under the
     Buyers' Contracts during the preceding Collection Period, provided,
     however, that if the total of such interest payments received is greater
     than the Buyers' Interest Amount for the Interest Period ending on such
     Settlement Date, then the amount of interest to be remitted may be reduced
     by the amount of such excess (such reduction being herein called the
     "Positive Interest Differential"); and

          (c) all other amounts received by the Servicer in respect of the
     Buyers' Contracts during the preceding Collection Period, including without
     limitation, proceeds received from any life, disability or property
     insurance and any other proceeds of or from Related Security, provided,
     however that if PDC is not in default under Section 4.2, PDC may retain any
     late charges received by PDC.

     Section 4.2. Additional Payments to Buyer.

          (a) If the Servicer shall have released any Related Security, the
     Servicer shall make the payment required by Section 9.1 with respect
     thereto on the Settlement Date next succeeding such release.

          (b) Should the amount of all payments of interest received during a
     Collection Period be less than the Buyers' Interest Amount for the Interest
     Period ending on the first Settlement Date after such Collection Period,
     PDC shall advance to the Agent, for the benefit of the Buyers, on the next
     Settlement Date the difference between the total of all such payments of
     interest and the Buyer's Interest Amount. The obligations of PDC under the
     preceding sentence shall be absolute and irrevocable, and shall not be
     affected by the Agent's termination of PDC's servicing agency pursuant to
     Section 3.4 or by any other event.

     Section 4.3. Defaulted Contracts. If a Contract Default shall have occurred
with respect to any Buyers' Contract and such Contract is not repurchased by the
Related Seller hereunder, the Servicer shall take all reasonable actions, which
may include filing lawsuits, to collect such Contract and to enforce the Agent's
and the Buyers' rights under any Related Security


                                       22
<PAGE>

Document. The proceeds of any action to collect such a Contract or of a sale of
any Related Security for such Contract shall be applied first to the Servicer's
reasonable out-of-pocket costs and expenses (including the fees and
disbursements of its counsel) incurred in obtaining such proceeds, second, to
the Agent's and the Buyers' reasonable costs and expenses (including the fees
and disbursements of its counsel), third, at the Agent's option, to accrued,
unpaid interest on the Contract or to the outstanding principal balance of the
Contract, fourth, to accrued, unpaid interest on the Contract or the outstanding
principal balance of the Contract (whichever was not chosen by the Agent
pursuant to clause third above), and the remainder, if any, to any other Person
legally entitled thereto, including, without limitation, the Related Seller.

     Section 4.4. Consideration to PDC. As full consideration for all of the
Servicer's servicing and collection functions hereunder and for the Servicer's
obligation to advance such additional amounts as may from time to time be
required hereunder, until the Servicer's servicing agency is terminated pursuant
to Section 3.4, the Servicer shall be entitled to receive for its individual
account, out of any Positive Interest Differentials and all earnings on the
Collection Account, subject to Section 4.6 below, a fee (the "Servicing Fee") in
an amount equal to 1% per annum of the outstanding principal balance of the
Buyer's Contracts. As full consideration for PDC's obligations under Section
4.2(b) and Article XII, PDC shall be entitled to receive for its individual
account the portion of the Positive Interest Differentials and all earnings on
the Collection Account described in Section 4.6(d) (the "Guaranty Fee"). The
Servicing Fee and the Guaranty Fee shall accrue and be calculated for each
Collection Period and payable on each Settlement Date. All collections will,
notwithstanding the terms of this Section 4.4, be deposited in the Collection
Account no later than the Business Day following PDC's receipt of immediately
available funds with respect thereto.

     Section 4.5. Payments by the Agent. Any amounts paid or prepaid on account
of the Buyers' Contracts or the Sellers' obligations with respect thereto shall
be paid to the Agent for the account of each Buyer in proportion to its
undivided percentage ownership interest of outstanding Buyers' Contracts. The
Agent will promptly distribute in like funds to each Buyer its ratable share of
each payment of principal, interest or fees received by the Agent for the
account of the Buyer.

     Section 4.6. Application of Positive Interest Differentials and Earnings on
Collection Account. On each Settlement Date, the Positive Interest Differential,
if any, and all earnings on the Collection Account shall be distributed as
follows:

          (a) first, to the Agent and the Buyers, in an amount sufficient to pay
     or reimburse all amounts owed to them hereunder;


                                       23
<PAGE>

          (b) second, to the Servicer, to reimburse the Servicer for all
     advances made by it pursuant to Section 4.2, in an amount up to the
     unreimbursed amount of all such advances made;

          (c) third, to the Servicer, in an amount equal to all accrued, unpaid
     Servicing Fees; and

          (d) fourth, to PDC, as the Guaranty Fee.

     Neither the Servicer nor PDS shall have any claim for reimbursement of
advances made pursuant to Section 4.2, the Servicing Fee or the Guaranty Fee
except as provided in this Section 4.6.

     permits, water discharge permits, hazardous waste permits or other


                                       29

     permits held by either Seller or any Subsidiary which are material to the
     operations of either Seller or such Subsidiary, or (ii) which will or
     threatens to impose a material liability on either Seller or such
     Subsidiary to any Person or which will require a material expenditure by
     either Seller or such Subsidiary to cure any alleged problem or violation.

          6.2(i) From time to time, such other information regarding the
     business, operation and financial condition of the Sellers and the
     Subsidiaries as the Agent or any Buyer may reasonably request.

     Section 6.3. Inspection. Each Seller shall permit any Person designated by
the Agent or any Buyer to visit and inspect any of that Seller's properties,
corporate books and financial records, to examine and to make copies of that
Seller's books of accounts and other financial records, and to discuss the
affairs, finances and accounts of that Seller and the Subsidiaries with, and to
be advised as to the same by, its officers at such reasonable times and
intervals as the Agent or any Buyer may designate. So long as no Termination
Event exists, such visits, inspections and examinations shall be at the expense
of the Agent or Buyer conducting such visit, inspection or examination, but any
such visits, inspections and examinations made while any Termination Event is
continuing shall be at the expense of the Sellers.

     Section 6.4. Fiscal Periods. Each Seller will have the same fiscal year and
schedule of fiscal months, determined for each year on a basis consistent with
PDC's historical practices. The Sellers will deliver a schedule of fiscal months
and Settlement Dates for each fiscal year to the Agent on or before the end of
the preceding fiscal year.

                                   -----------
                   SELLERS' OBLIGATION TO REPURCHASE CONTRACTS

     Each Seller shall have an obligation to repurchase Contracts, as follows:

     Section 7.1. Sellers' Obligations to Repurchase.

          7.1(a) Repurchases Without Limit. Each Seller agrees to repurchase, on
     the Agent's demand, any Contract previously purchased by the Buyers from
     that Seller hereunder:

               (i) If such Contract was not, on the applicable Purchase Date, an
          Eligible Contract;

               (ii) If any representation or warranty by that Seller with
          respect to such Contract was not true and correct on the applicable
          Purchase Date;


                                       30
<PAGE>

               (iii) Upon any failure by that Seller, or by the Servicer, to
          comply with any of its covenants or other agreements hereunder with
          respect to such Contract; and

               (iv) If such Contract is or becomes subject to any Liens or other
          adverse claims created by or arising through that Seller.

          7.1(b) Limited Repurchases Following Contract Default. In addition to
     any repurchases required by Section 7.1(a), each Seller agrees to
     repurchase, on the Agent's demand, any Contract previously purchased by the
     Buyers from that Seller hereunder upon the occurrence of a Contract Default
     with respect to such Contract; provided, however that a Seller shall not be
     obligated to repurchase any Contract pursuant to this Section 7.1(b) if the
     principal amount outstanding under that Contract exceeds the remainder of
     that Seller's Individual Repurchase Commitment Amount as of the date of
     determination; and provided further that neither Seller shall be obligated
     to repurchase a Contract pursuant to this Section 7.1(b) if such repurchase
     would cause the portion of the aggregate Repurchase Price for all Contracts
     repurchased after the Closing Date under this Section 7.1(b) that is
     attributable to principal outstanding under such Contracts to exceed the
     Aggregate Repurchase Commitment Amount.

     Section 7.2. Seller's Option to Repurchase. If on any Settlement Date the
aggregate outstanding principal balance of the Buyers' Contracts is less than or
equal to $1,000,000, the Sellers may repurchase from the Buyers all but not less
than all of such Contracts for the Repurchase Price.

     Section 7.3. Terms of Repurchase. Repurchases of Contract(s) by a Seller
under the provisions of this Article VII shall be made by payment of the
Repurchase Price for such Contract(s) to the Agent for the benefit of the
Buyers. Each repurchase by a Seller from the Buyers under this Article VII shall
be made in Immediately Available Funds and shall be without recourse,
representation or warranty except as to the absence of encumbrances created by
the Buyers. In the event a Seller is obligated to repurchase a Contract under
the provisions of this Article VII, the Agent shall, at that Seller's expense
and after payment of the full Repurchase Price therefor, take such action as
that Seller may reasonably request in order to reassign to that Seller the
Contract, all Related Security Documents and all Related Security for such
Contract. Notwithstanding any other provision hereof, following the repurchase
of a Contract by a Seller and payment of the full Repurchase Price therefor, the
Agent and the Buyers shall have no further rights therein and all collections on
such repurchased Contract shall be the sole property of that Seller.

                                  ARTICLE VIII
                                  ------------
                     SELLERS' REPRESENTATIONS AND WARRANTIES

     In order to induce the Agent and the Buyers to execute this Agreement and
to purchase Contracts hereunder, the Sellers make the following representations
and warranties to the Agent and the Buyers, each of which shall survive the
execution and delivery of this Agreement and shall be deemed given as of the
date hereof and as of each Purchase Date:

     Section 8.1 Organization; Standing, Etc. PDC and each of its corporate
Subsidiaries, including PDSI, are corporations duly incorporated and validly
existing and in good standing under the laws of the jurisdiction of their
respective incorporation and have all requisite corporate power and authority to
carry on their respective businesses as now conducted and to (in the instance of
the Sellers) enter into this Agreement, the Guaranties and the Assignments and
to perform their obligations under this Agreement, the Guaranties and the
Assignments. PDC and each of its Subsidiaries, including PDSI, are duly
qualified and in good standing as a foreign corporation in each jurisdiction in
which the character of the properties owned, leased or operated by it or the
business conducted by it makes such qualification necessary and where failure to
so qualify or to maintain such good standing would constitute an Adverse Event.

     Section 8.2. Authorization and Validity. The execution, delivery and
performance by the Sellers of this Agreement, the Guaranties and the Assignments
have been duly authorized by all necessary corporate action by the Sellers, and
this Agreement, the Guaranties and the Assignments constitute the legal, valid
and binding obligations of the Sellers, enforceable against the Sellers in
accordance with their respective terms, subject to limitations as to
enforceability which might result from bankruptcy, insolvency, moratorium and
other similar laws affecting creditors' rights generally and subject to
limitations on the availability of equitable remedies.

     Section 8.3. No Conflict; No Default. The execution, delivery and
performance by the Sellers of this Agreement, the Guaranties and the Assignments
will not (a) violate any provision of any law, statute, rule or regulation or
any order, writ, judgement, injunction, decree, determination or award of any
court, governmental agency or arbitrator presently in effect having
applicability to either Seller, (b) violate or contravene any provisions of the
Articles (or Certificate) of Incorporation or by-laws of either Seller, or (c)
result in a breach of or constitute a default under any indenture, loan or
credit agreement or any other agreement, lease or instrument to which either
Seller is a party or by which it or any of its properties may be bound or result
in the creation of any Lien on any asset of either Seller or any Subsidiary.
Neither a Seller nor any Subsidiary is in default under or in violation of any
such law, statute, rule or regulation, order, writ, judgment, injunction,
decree, determination or award or any such indenture, loan or credit agreement
or other agreement, lease or instrument in any case in which the consequences of
such default or violation could constitute an Adverse Event.


                                       32
<PAGE>

     Section 8.4. Government Consent. No order, consent, approval, license,
authorization or validation of, or filing, recording or registration with, or
exemption by, any governmental or public body or authority is required on the
part of either Seller to authorize, or is required in connection with the
execution, delivery and performance of, or the legality, validity, binding
effect or enforceability of, this Agreement, the Guaranties and the Assignments.

     Section 8.5. Financial Statements and Condition. PDC's audited consolidated
financial statements as at April 24, 1999 and its unaudited consolidated
financial statements as at January 21, 2000, as heretofore furnished to the
Agent, have been prepared in accordance with GAAP on a consistent basis and
fairly present the financial condition of PDC and its Subsidiaries as at such
dates and the results of their operations and changes in financial position for
the respective periods then ended. As of the dates of such financial statements,
neither a Seller nor any Subsidiary had any material obligation, contingent
liability, liability for taxes or long-term lease obligation which is not
reflected in such financial statements or in the notes thereto. Since April 24,
1999, no Adverse Event has occurred.

     Section 8.6. Litigation and Contingent Liabilities. Except as previously
disclosed to the Buyers in writing, there are no actions, suits or proceedings
pending or, to the knowledge of either Seller, threatened against or affecting
either Seller or any Subsidiary or any of their properties before any court or
arbitrator, or any governmental department, board, agency or other
instrumentality which, if determined adversely to either Seller or such
Subsidiary, could constitute an Adverse Event.

     Section 8.7. Compliance. PDC and its Subsidiaries, including PDSI, are in
material compliance with all statutes and governmental rules and regulations
applicable to them.

     Section 8.8. Environmental, Health and Safety Laws. There does not exist
any violation by either Seller or any Subsidiary of any applicable federal,
state or local law, rule or regulation or order of any government, governmental
department, board, agency or other instrumentality relating to environmental,
pollution, health or safety matters which will or threatens to impose a material
liability on either Seller or a Subsidiary or which would require a material
expenditure by either Seller or such Subsidiary to cure. Neither a Seller nor
any Subsidiary has received any notice to the effect that any part of its
operations or properties is not in material compliance with any such law, rule,
regulation or order or notice that it or its property is the subject of any
governmental investigation evaluating whether any remedial action is needed to
respond to any release of any toxic or hazardous waste or substance into the
environment, the consequences of which non-compliance or remedial action could
constitute an Adverse Event.

     Section 8.9. ERISA. Each Plan complies with all material applicable
requirements of ERISA and the Code and with all material applicable rulings and
regulations issued under the provisions of ERISA and the Code setting forth
those requirements. No Reportable Event,


                                       33
<PAGE>

other than a Reportable Event for which the reporting requirements have been
waived by regulations of the PBGC, has occurred and is continuing with respect
to any Plan. All of the minimum funding standards applicable to such Plans have
been satisfied and there exists no event or condition which would permit the
institution of proceedings to terminate any Plan under Section 4042 of ERISA.
The current value of the Plans' benefits guaranteed under Title IV of ERISA does
not exceed the current value of the Plans' assets allocable to such benefits.

     Section 8.10. Regulation U. Neither Seller is engaged in the business of
extending credit for the purpose of purchasing or carrying margin stock (as
defined in Regulation U of the Board of Governors of the Federal Reserve System)
and no part of the proceeds of any purchase of Contracts by the Buyers hereunder
will be used to purchase or carry margin stock or for any other purpose which
would violate any of the margin requirements of the Board of Governors of the
Federal Reserve System.

     Section 8.11. Liens. None of the Accounts or Inventory of either Seller or
any Subsidiaries is subject to a Lien, except for Permitted Liens.

     Section 8.12. Taxes. Each of the Sellers and the Subsidiaries has filed all
federal, state and local tax returns required to be filed and has paid or made
provision for the payment of all taxes due and payable pursuant to such returns
and pursuant to any assessments made against it or any of its property and all
other taxes, fees and other charges imposed on it or any of its property by any
governmental authority (other than taxes, fees or charges the amount or validity
of which is currently being contested in good faith by appropriate proceedings
and with respect to which reserves in accordance with GAAP have been provided on
the books of PDC). No tax Liens have been filed and no material claims are being
asserted with respect to any such taxes, fees or charges. The charges, accruals
and reserves on the books of the Sellers in respect of taxes and other
governmental charges are adequate.

     Section 8.13. Investment Company Act. Neither a Seller nor any Subsidiary
is an "investment company" or a company "controlled" by an investment company
within the meaning of the Investment Company Act of 1940, as amended.

     Section 8.14. Public Utility Holding Company Act. Neither a Seller nor any
Subsidiary is a "holding company" or a "subsidiary company" of a holding company
or an "affiliate" of a holding company or of a subsidiary company of a holding
company within the meaning of the Public Utility Holding Company Act of 1935, as
amended.

     Section 8.15. Subsidiaries. Exhibit H sets forth as of the date of this
Agreement a list of all Subsidiaries and the number and percentage of the shares
of each class of capital stock owned beneficially or of record by the Seller or
any Subsidiary therein, and the jurisdiction of incorporation of each
Subsidiary. PDSI is a wholly owned Subsidiary of PDC.


                                       34

     Section 8.16. Partnerships and Joint Ventures. Neither a Seller nor any
Subsidiary is currently a partner (limited or general) or joint venturer in any
partnership or joint venture.

     Section 8.17. Enforceability of Agreements and Assignments. This Agreement
has been duly executed and delivered by each Seller and is a valid and binding
agreement of each Seller enforceable in accordance with its terms. Each
Assignment, upon delivery to the Agent, will have been duly executed and
delivered by the Related Seller with respect to the Contracts subject to that
Assignment and will constitute a valid and binding assignment by the Related
Seller enforceable against the Related Seller in accordance with its terms. Each
Seller has full right, power and authority to sell the Contracts, the Related
Security, the Related Security Documents and proceeds hereunder and has the
ability to fulfill completely its obligations to the Obligors with respect to
the Contracts.

     Section 8.18. Sale of Contracts. On each Purchase Date the Related Seller
will be the owner of all right, title and interest in and to the Contracts to be
sold to the Buyers on such Purchase Date, all Related Security Agreements and
the Related Seller's interest in the Related Security and upon the delivery of
the Assignment to the Buyer on such Purchase Date, such ownership interest will
be vested in the Buyer. Each Contract offered to and/or purchased by the Buyers
hereunder, all Related Security Agreements and the Related Seller's interest in
the Related Security will be, when offered and/or purchased, owned by the
Related Seller free and clear of all Liens and rights of others excepting the
rights in favor of the Agent and the Buyers created or to be created pursuant to
this Agreement. Except in connection with the sale of Contracts hereunder,
neither Seller has sold, pledged, transferred, assigned or granted any Lien in
any Contracts sold or to be sold to the Buyers hereunder, any Related Security
or the Related Security Documents. No financing statement describing or
referring to any Contract (other than any financing statement naming the Agent
as secured party) is on file in any public office, except for financing
statements in favor of U.S. Bank and BA Credit Corporation. There is only one
original executed copy of each Contract, and such original executed copy of each
Contract purchased by the Buyers will be delivered to the Agent on the relevant
Purchase Date.

     Section 8.19. Related Security. Immediately prior to the purchase of any
Contract on a Purchase Date, the Related Seller will have a perfected first
priority Lien on all Related Security for such Contract. Following the
assignment of each Contract to the Agent for the benefit of the Buyers, the
Buyers will have a valid and perfected and enforceable first priority security
interest in each Contract and the Related Security. With respect to each
Contract, the dental equipment included in the Related Security is located in a
state in which the filing of a financing statement under the UCC is required to
perfect a security interest in goods of the type including such dental
equipment; such filings have been duly made and show the Related Seller as
secured party; and the Agent has the same rights as the secured party of record
would have (if such secured party were still the owner of the Contract) against
all Persons (including the Related Seller and any trustee in bankruptcy of the
Related Seller) claiming an interest in such dental equipment included in the
Related Security.

     Section 8.20. Eligibility and Enforceability of Contracts; Accuracy of
Information; Compliance. As of the relevant Purchase Date, each Contract sold to
the Buyers by a Seller hereunder is an Eligible Contract. Each Contract sold to
the Buyers by a Seller hereunder, and all Related Security Documents, will
constitute the legal, valid and binding obligation of the Obligor(s) thereof,
enforceable in accordance with their respective terms. Each such Contract will
accurately reflect the name(s) and residence or business address of the
Obligor(s), the signature(s) of the Obligor(s) on each Contract are genuine and
all parties to each Contract had full legal capacity to execute that Contract.
At the date of origination of each Contract, and on the Purchase Date with
respect thereto, all requirements of any federal and state laws, rules and
regulations applicable to the Contract, including, without limitation, usury,
truth in lending and equal credit opportunity laws, have been complied with, and
the Related Seller shall for at least the period of this Agreement, maintain in
its possession, available for the Agent's and the Buyers' inspection, and shall
deliver to the Agent upon demand, evidence of compliance with all such
requirements. Such compliance is not affected by the Buyers' ownership of the
Contracts.

     Section 8.21. Contract Defaults. As of the relevant Purchase Date: (i) each
Contract sold to the Buyers by a Seller hereunder will be current, or no more
than 60 days past due; (ii) there will be no default, breach, violation or event
permitting acceleration existing under the Contract and no event which, with
notice and the expiration of any grace or cure period, would constitute such a
default, breach, violation or event permitting acceleration under such Contract
(except payment delinquencies permitted by clause (i) above); (iii) neither the
Related Seller nor the Servicer will have waived any such default, breach,
violation or event permitting acceleration except payment delinquencies
permitted by clause (i) above; (iv) the Related Security will be free of damage
and in good repair; (v) each Contract will not have had its terms of payment
extended or modified in a manner inconsistent with the Related Seller's normal
credit policies; (vi) each Contract has not been satisfied or subordinated in
whole or in part or rescinded, and the Related Security securing each Contract
has not been released from the lien of the Contract in whole or in part. Neither
Seller has changed its credit and collection policies in any material respect or
taken any action which would materially impair the collectability of any
Contract.

     Section 8.22. Goods Sold. Immediately prior to the date on which title to
any goods sold to an Obligor by a Seller and financed by indebtedness evidenced
by a Contract or Contracts passes to the Obligor thereof, the Related Seller
shall have been the owner of such goods free and clear of all mortgages, deeds
of trust, pledges, liens, security interests and other charges or encumbrances.
As of the Purchase Date with respect to each Contract, there will be no liens or
claims filed for work, labor or materials affecting the Related Security
securing the Contract which are or may be liens prior to, or equal or coordinate
with, the lien of the Contract.

     Section 8.23. Financing Statements. Appropriate Uniform Commercial Code
financing statements relating to the sale of Contracts hereunder have been filed
in all offices


                                       36
<PAGE>

where such filing is necessary to give the Agent on behalf of the Buyers a prior
perfected security interest in the Buyers' Contracts, the Related Security
Documents and any Related Security superior to any other interest therein. The
Buyers' Contracts, the Related Security Documents and any Related Security are
or will be sufficiently described in the Assignments and such financing
statements in order to perfect and protect Buyers' interest in the Buyers'
Contracts, the Related Security Documents and any Related Security against all
other Persons. All filing fees and taxes, if any, necessary to make the
foregoing filing effective have been paid in full.

     Section 8.24. Records. Both Sellers' chief executive office and the place
where they maintain the books and records relating to the Contracts and any
Related Security is located at 1031 Mendota Heights Road, St. Paul, Minnesota
55120.

     Section 8.25. Licenses. All import and exchange licenses, if required under
applicable law or regulations for the exportation, importation and payment of
the purchase price and related costs of goods underlying the Contracts or the
shipment thereof, have been obtained.

     Section 8.26. No Defenses or Waivers. As of the Purchase Date with respect
to each Contract: (i) the Contract is not subject to any right of rescission,
setoff, counterclaim or defense, including the defense of usury; (ii) the
operation of any of the terms of the Contract or the exercise of any right
thereunder will not render the Contract unenforceable in whole or in part or
subject to any right of rescission, setoff, counterclaim or defense, including
the defense of usury; (iii) no such right of rescission, setoff, counterclaim or
defense has been asserted with respect thereto; and (iv) the terms of the
Contract have not been waived, altered or modified in any respect, except by
instruments or documents identified in the exhibits to the relevant Assignment.

     Section 8.27.Insurance Coverage. The Obligor under each Contract is
contractually obligated to maintain all risk physical damage insurance upon the
equipment securing such Contract in an amount at least equal to the lesser of
the principal amount of such Contract or the replacement cost of such equipment,
which insurance policy must name the Related Seller as loss payee and additional
insured and require at least 10 days' prior written notice to the Related Seller
before cancellation. In the case of any Contract as to which the unpaid
principal balance as of the Purchase Date with respect to such Contract exceeds
$100,000, the Related Seller has obtained written proof of such insurance.

     Section 8.28. Origination. Each Contract was originated by the Related
Seller in the ordinary course of its business. No Contract was originated in or
is subject to the laws of any jurisdiction whose laws would make the transfer of
the Contract pursuant to this Agreement, or the ownership of the Contract by the
Buyers, unlawful or render the Contract unenforceable as a result thereof.


                                       37
<PAGE>

     Section 8.29. Retirement Benefits. Except as required under Section 4980B
of the Code, Section 601 of ERISA or applicable state law, neither a Seller nor
any Subsidiary is obligated to provide post-retirement medical or insurance
benefits with respect to employees or former employees.

     Section 8.30. Full Disclosure. Subject to the following sentence, neither
the financial statements referred to in Sections 6.2 or 8.5 nor any other
certificate, written statement, exhibit or report furnished by or on behalf of
either Seller in connection with or pursuant to this Agreement contains any
untrue statement of a material fact or omits to state any material fact
necessary in order to make the statements contained therein not misleading.
Certificates or statements furnished by or on behalf of either Seller to the
Agent or the Buyers consisting of projections or forecasts of future results or
events have been prepared in good faith and based on good faith estimates and
assumptions of the management of that Seller, and the Sellers have no reason to
believe that such projections or forecasts are not reasonable.


                                   ARTICLE IX
                                   ----------
                        SELLERS' AGREEMENTS WITH RESPECT
                        TO CONTRACTS AND RELATED SECURITY

     In order to induce the Agent and the Buyers to execute this Agreement and
to purchase Contracts hereunder, the Sellers jointly and severally agree that,
with respect to each Buyers' Contract, for as long as such Contract or any
amount thereunder remains outstanding, and whether or not the Agent has
terminated PDC as Servicer of such Contract under Section 3.4:

     Section 9.1. Modification of Contracts. Except as provided in the remainder
of this Section 9.1, neither Seller nor the Servicer will, as agent of the Agent
and the Buyers or otherwise, extend or otherwise compromise or modify the terms
of any Buyers' Contract or the terms of any Related Security Documents without
the prior written approval of the Agent, release any Related Security or alter
or amend in any material respect its credit policies with respect to Contracts,
Related Security Documents and Related Security as in effect on the date hereof.
The foregoing shall not prohibit the Servicer, as long as the Agent has not
terminated PDC's power to act as Servicer pursuant to Section 3.4, from
modifying the terms of any Buyers' Contract in a manner consistent with the the
Servicer's credit polices as they exist as of the date of this Agreement,
provided that (a) notice of such modification is included in each settlement
statement delivered to the Agent pursuant to Section 6.1 with respect to the
Collection Period during which such modification occurred, (b) the Servicer does
not permit more than one such modification to the amortization schedule with
respect to any Contract, (c) no modification extends the date for final payment
under a Contract beyond the Final Maturity Date, (d) if any modification
releases any Related Security, the Servicer pays to the Agent for the benefit of
the Buyers on the next Settlement Date an amount equal to the portion of the
principal amount outstanding under the modified Contract that is attributable to
the released Related Security, (e) no modification may reduce the interest rate


                                       38
<PAGE>

payable on a Contract (other than a Discounted Contract) below the Buyers' Rate
in effect as of the date of the modification, (f) no modification may reduce the
principal amount outstanding under a Contract without the Buyers' prior consent,
and (g) no Contract may be modified pursuant to this Section 9.1 that would
cause the aggregate Purchase Price of all Contracts that have been modified by
the Servicer under this Section 9.1 to be ten percent (10%) or more of the
aggregate Purchase Price of all Buyers' Contracts.

     Section 9.2. Assignments. Each Assignment executed and delivered in
connection with any purchase and sale of Contracts will vest in the Agent on
behalf of the Buyers all of the Related Seller's right, title and interest in
and to such Contracts, any Related Security, any Related Security Documents and
the proceeds thereof.

     Section 9.3. Adverse Interests. Neither Seller will, as agent for the
Agent, the Buyers or otherwise, pledge, hypothecate, convey or otherwise
transfer, or grant any security or other interest in, any Buyers' Contract or
any Related Security or Related Security Document.

     Section 9.4. Continuation of Related Security. The Servicer shall maintain
in full force and effect, in the name of the Related Seller (unless assigned to
the Agent for the benefit of the Buyers by the Seller's execution and delivery
to the Agent of a UCC assignment), all Liens constituting Related Security for
Buyers' Contracts sold by that Seller, with the priority such Liens had on the
applicable Purchase Date, until all amounts owing under the related Contract
have been paid in full.

     Section 9.5. Taxes and Claims. Each Seller will promptly pay all taxes and
other governmental charges levied or assessed upon or against any of the Buyers'
Contracts sold by that Seller and the Related Security or upon or against the
creation, perfection or continuance of the Buyers' interest therein, as well as
all other claims of any kind (including claims for labor, material and supplies)
against or with respect to any such Contract or Related Security, except to the
extent (a) such taxes, charges or claims are being contested in good faith by
appropriate proceedings, (b) such proceedings do not involve any material danger
of the sale, forfeiture or loss of any of the Buyers' Contracts or Related
Security or any interest therein and (c) such taxes, charges or claims are
adequately reserved against on the Seller's books in accordance with generally
accepted accounting principles.

     Section 9.6. Further Assurances.

          9.6(a) Each Seller and the Servicer 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 may be necessary or that
     the Agent or a Buyer may reasonably request, in order to perfect and
     protect the sale of the Buyers' Contracts, the Related Security, the
     Related Security Documents and proceeds hereunder or to enable the Agent or
     a Buyer to exercise and enforce its rights and remedies hereunder with
     respect to any of such Contracts, Related Security, Related Security
     Documents

     and proceeds (but any failure to request or assure that a Seller execute
     and deliver such instrument or documents or to take such action shall not
     affect or impair the validity, sufficiency or enforceability of this
     Agreement and the sale of the Contracts hereunder, regardless of whether
     any such item was or was not executed and delivered or action taken in a
     similar context or on a prior occasion). Without limiting the generality of
     the foregoing, each Seller will, promptly and from time to time at the
     request of the Agent, execute and file such financing statements or
     continuation statements in respect thereof, or amendments thereto, and such
     other instruments or notices, as the Agent may reasonably request, in order
     to perfect, preserve, and enhance the sale of the Buyers' Contracts sold by
     that Seller, the Related Security, the Related Security Documents and
     proceeds hereunder and attempt to obtain waivers, in form satisfactory to
     the Agent, of any claim to any such Contracts, Related Security or Related
     Security Documents from any other party claiming or in a position to claim
     an interest therein.

          9.6(b) Each Seller hereby authorizes the Agent to file one or more
     financing statements or continuation statements in respect thereof, and
     amendments thereto, relating to all or any part of the Buyers' Contracts
     sold by that Seller, the Related Security, the Related Security Documents
     and proceeds without the signature of the Seller where permitted by law. A
     photocopy or other reproduction of this Agreement or any financing
     statement covering the Contracts, Related Security, Related Security
     Documents and proceeds or any part thereof shall be sufficient as a
     financing statement where permitted by law.

          9.6(c) The Servicer will furnish to the Agent from time to time
     statements and schedules further identifying and describing the Buyers'
     Contracts or Related Security and such other reports in connection with the
     Buyers' Contracts or Related Security as the Agent may reasonably request,
     all in reasonable detail and in form and substance reasonably satisfactory
     to the Agent.

          9.6(d) Each Seller shall, at the request of the Agent, deliver or
     cause the Servicer to deliver the originals of all Related Security
     Documents to the Agent, and allow the Agent to verify that the Sellers or
     the Servicer marked all of its relevant records to show the Buyers'
     ownership of the Buyers' Contracts, Related Security and Related Security
     Documents by labeling the same "Property of U.S. Bank National Association,
     as agent for the benefit of the 'Buyers' as defined in that certain Second
     Amended and Restated Contract Purchase Agreement dated as of April 28, 2000
     by and between Patterson Dental Company, Patterson Dental Supply, Inc.,
     U.S. Bank National Association, individually and as agent, The Bank of
     Tokyo - Mitsubishi, Ltd., M&I Marshall & Ilsley Bank and The Northern Trust
     Company."

     Section 9.7. Secured Party Subsidiaries. If any Subsidiary of PDC at any
time becomes a secured party or creditor with respect to any Obligor, PDC shall
cause such


                                       40
<PAGE>

Subsidiary to conduct its business with such Obligor in a manner such that no
defense to such Obligor's obligations under any Buyers' Contract arise from the
Obligor's relationship with such Subsidiary.

                                GENERAL COVENANTS

     In order to induce the Agent and the Buyers to execute this Agreement and
to purchase Contracts hereunder, the Sellers jointly and severally agree that,
until the Contract Purchase Commitment shall have expired or been terminated and
all Buyers' Contracts have been paid in full, unless the Majority Banks shall
otherwise consent in writing:

     Section 10.1. Corporate Existence. Subject to Section 10.9 in the instance
of a Subsidiary, each of the Sellers and each Subsidiary will maintain its
corporate existence in good standing under the laws of its jurisdiction of
incorporation and its qualification to transact business in each jurisdiction in
which the character of the properties owned, leased or operated by it or the
business conducted by it makes such qualification necessary and where the
failure so to qualify or to maintain such good standing would constitute an
Adverse Event.

     Section 10.2. Insurance. Each of the Sellers and each Subsidiary will
maintain with financially sound and reputable insurance companies such insurance
as may be required by law and such other insurance in such amounts and against
such hazards as is customary in the case of reputable corporations engaged in
the same or similar business and similarly situated.

     Section 10.3. Payment of Taxes and Claims. Each of the Sellers and each
Subsidiary will file all tax returns and reports which are required by law to be
filed by it and pay before they become delinquent all taxes, assessments and
governmental charges and levies imposed upon it or its property and all claims
or demands of any kind (including, without limitation, those of suppliers,
mechanics, carriers, warehouses, landlords and other like Persons) which, if
unpaid, might result in the creation of a Lien upon its property; provided that
the foregoing items need not be paid if they are being contested in good faith
by appropriate proceedings, and as long as the Seller's or such Subsidiary's
title to its property is not materially adversely affected, its use of such
property in the ordinary course of its business is not materially interfered
with and adequate reserves with respect thereto have been set aside on the
Seller's or such Subsidiary's books in accordance with GAAP.

     Section 10.4. Maintenance of Properties. Each of the Sellers and each
Subsidiary will maintain its properties used or useful in the conduct of its
business in good condition, repair and working order, and supplied with all
necessary equipment, and make all necessary repairs, renewals, replacements,
betterments and improvements thereto, all as may be necessary so that the
business carried on in connection therewith may be properly and advantageously
conducted at all times.

     Section 10.5. Books and Records. Each of the Sellers and each Subsidiary
will keep adequate and proper records and books of account in which full and
correct entries will be made of its dealings, business and affairs.

     Section 10.6. Compliance. Each of the Sellers and each Subsidiary will
comply in all material respects with all laws, rules, regulations, orders,
writs, judgments, injunctions, decrees or awards to which it may be subject.

     Section 10.7. ERISA. Each of the Sellers and each Subsidiary will maintain
each Plan in compliance with all material applicable requirements of ERISA and
of the Code and with all material applicable rulings and regulations issued
under the provisions of ERISA and of the Code.

     Section 10.8. Environmental Matters. Each of the Sellers and each
Subsidiary will observe and comply with all laws, rules, regulations and orders
of any government or government agency relating to health, safety, pollution,
hazardous materials or other environmental matters to the extent non-compliance
could result in a material liability or otherwise constitute an Adverse Event.

     Section 10.9. Merger. Neither a Seller nor any Subsidiary will merge or
consolidate or enter into any analogous reorganization or transaction with any
Person, unless PDC shall be the surviving corporation and no Default or Event of
Default shall exist before and after giving effect to such merger,
consolidation, reorganization, or transaction; provided, however, any
wholly-owned Subsidiary may be merged with or liquidated into a Seller (if the
Seller is the surviving corporation) or any other wholly-owned Subsidiary.

     Section 10.10. Sale of Assets. Neither a Seller nor any Subsidiary will
sell, transfer, lease or otherwise convey all or any substantial part of its
assets except for sales and leases of inventory in the ordinary course of
business and except for sales or other transfers by a wholly-owned Subsidiary to
the Seller or another wholly-owned Subsidiary; provided, however, that the
foregoing shall not prohibit the Permitted Account Sales or the capitalization
of PDSI by a contribution of the distribution centers, warehouses, sales offices
and related assets owned by PDC if and only if PDSI is a wholly-owned Subsidiary
of PDC (and any such capitalization and contribution shall not be deemed to be a
change in the nature of PDC's or PDSI's business in violation of Section 10.12).

     Section 10.11. Plans. Neither a Seller nor any Subsidiary will permit any
condition to exist in connection with any Plan which might constitute grounds
for the PBGC to institute proceedings to have such Plan terminated or a trustee
appointed to administer such Plan, permit any Plan to terminate under any
circumstances which would cause the lien provided for in Section 4068 of ERISA
to attach to any property, revenue or asset of a Seller or any Subsidiary or
permit the underfunded amount of Plan benefits guaranteed under Title IV of
ERISA to exceed $500,000.

Subsidiary will make any material change in the nature of the business of the
Seller or such Subsidiary, as carried on at the date hereof.

     Section 10.13. Liens. Neither a Seller nor any Subsidiary will create,
incur, assume or suffer to exist any Lien on any Account or Inventory, except
for Permitted Liens.

     Section 10.14. Use of Proceeds. Neither a Seller nor any Subsidiary will
permit any proceeds of the sales of the Contracts to be used, either directly or
indirectly, for the purpose, whether immediate, incidental or ultimate, of
"purchasing or carrying any margin stock" within the meaning of Regulation U of
the Federal Reserve Board, as amended from time to time, and each Seller will
furnish to the Buyer, upon its request, a statement in conformity with the
requirements of Federal Reserve Form U-1 referred to in Regulation U.

     Section 10.15. Current Ratio. PDC will not permit the ratio of its
consolidated current assets to its consolidated current liabilities plus,

Agreement) outstanding (whether or not current liabilities) to be less than
1.50:1.00 at any time.

     Section 10.16. Tangible Net Worth. PDC will not permit its Consolidated
Tangible Net Worth at any time to be less than the sum of (a) $75,000,000, plus
(b) 75% of the cumulative net income for all periods following the fiscal
quarter of PDC ending July 27, 1996 (without taking into account any net loss in
any such period), plus (c) 90% of the net proceeds of any issuance after July
27, 1996 of common or preferred stock, convertible debentures, or any other
equity interests in PDC.

     Section 10.17. Leverage Ratio. PDC will not permit the ratio of its
consolidated total liabilities plus "Deferred Credits" (as defined in the Credit
Agreement) to Consolidated Tangible Net Worth to be more than 1.50:1.00 at any
time.

     Section 10.18. Accounting Changes. The Sellers will not, and will not
permit any Subsidiary to, make any change in accounting treatment or reporting
practices, except as required by GAAP, that would have a significant effect on
any determination made or required to be made hereunder, or change their fiscal
year or the fiscal year of any Subsidiary.

     Section 10.19. Changes in Name or Location. Neither Seller will at any time
change its name, identity, address of its chief executive office or corporate
structure in any manner which would, could or might make any financing or
continuation statement filed hereunder seriously misleading within the meaning
of ss. 9-402(7) (or similar section) of any applicable enactment of the Uniform
Commercial Code or transact any business with respect to Contracts under a name
other than its present corporate title unless in either case it shall have given
the Agent at least sixty (60) days prior written notice thereof and shall have
made and cause to be filed such amendments to the financing statements filed
hereunder or such


                                       43
<PAGE>

financing statements as are necessary to maintain the perfection and priority of
the Buyers' security interest or as may be requested by the Agent.

     Section 10.20. Indemnity. The Sellers hereby agree, jointly and severally,
to indemnify and defend the Agent and the Buyers against all losses, damages,
costs, expenses, claims and liabilities (including, without limitation, the
Agent's and the Buyers' reasonable out-of-pocket expenses and reasonable fees
and expenses of counsel):

          10.20(a) arising out of or resulting from (i) the use, ownership,
     operation, sale or consumption by any Obligor, or any agent, employee or
     customer of any Obligor, of any product distributed by a Seller or which at
     any time was or shall have been related to any financing transaction from
     which a Buyers' Contract arises, or (ii) any breach of warranty or alleged
     breach of warranty by a Seller or any other Person, or (iii) any failure of
     any Buyers' Contract or Related Security Document at any time to comply
     with any legal requirement;

          10.20(b) arising from the assertion by an Obligor of any right to
     set-off against amounts owing under any Contract or Related Security any
     claim of whatsoever nature against a Seller or its employees or agents;

          10.20(c) relating to license and registration fees, duties or other
     similar charges (including without limitation, any charges related to doing
     business in a particular jurisdiction), or taxes, imposed or assessed
     (including without limitation, any penalties, fees, additions to tax or
     interest thereon, but excluding taxes imposed on the overall net income of
     a Buyer by the United States or the jurisdiction in which the Buyer has its
     principal office) by any government or taxing authority upon or with
     respect to amounts received as collections on the Contracts solely as a
     result of the Buyers' ownership of any Contract;

          10.20(d) actually incurred by the Agent or a Buyer by reason of the
     existence of any lien or encumbrance (other than those in favor of or
     created by the Agent or a Buyer) on any Buyers' Contract, Related Security
     Document or Related Security;

          10.20(e) arising by reason of, relating to or in connection with the
     execution, delivery, performance or enforcement of this Agreement, any
     Assignment or any transaction contemplated hereby or thereby; and

          10.20(f) arising by reason of, relating to or in connection with the
     purchase of any Contracts, Related Security, Related Security Documents and
     proceeds hereunder, or any act done or omitted by any Person with respect
     thereto or the exercise of any rights or remedies thereunder (other than
     nonpayment by an Obligor, or any other Contract Default, not attributable
     to or caused by the failure of the Contract to


                                       44
<PAGE>

     constitute an Eligible Contract or the actions or failure to act of the
     Sellers or the Servicer).

provided, however, that the Sellers shall not be liable to the Agent or a Buyer
for any portion of such losses, damages, costs, expenses, claims and liabilities
resulting from: (i) such Person's gross negligence or willful misconduct, or
(ii) the acts or omissions of any Person appointed by the Agent (after the
removal of PDC as Servicer) as the successor servicer for the Buyers' Contracts.
In the event this indemnity is unenforceable as a matter of law as to a
particular matter or consequence referred to herein, it shall be enforceable to
the full extent permitted by law. The foregoing indemnifications shall survive
full payment, any repurchase by or assignment to a Seller of any Contract and
the termination of this Agreement as provided in Section 13.14 hereof. The
Sellers will jointly and severally indemnify the Agent and the Buyers and save
them harmless from and against any claims, actions, damages, losses or expenses
(including reasonable attorneys' fees and court costs) awarded against or
incurred by the Agent or a Buyer as a result of any breach of this covenant.

     Section 10.21. Filing Fees. Each Seller shall pay all filing fees and other
expenses incurred by the Agent to validate, perfect, continue or otherwise
protect the Buyers' interest in the Contracts sold by that Seller, any Related
Security and any Related Security Documents, including appropriate filings under
the Uniform Commercial Code.

     Section 10.22. Guaranties. When so requested by the Agent from time to
time, each Guarantor will execute and deliver to the Agent reaffirmations of
their respective Guaranties in such form as the Agent may require.

     Section 10.23 Year 2000 Compliance. The Sellers have reviewed and assessed
their business operations and computer systems and applications to address the
"year 2000 problem" (that is, that computer applications and equipment used by
the Sellers, directly or indirectly through third-parties may have been or may
be unable to properly perform date-sensitive functions before, during and after
January 1, 2000). The Sellers represent and warrant that the year 2000 problem
has not resulted in and will not result in a material adverse change in the
Sellers' business condition (financial or otherwise), operations, properties or
prospects, or ability to pay the Buyers. The Sellers agree that this
representation shall be true and correct on and shall be deemed made by the
Sellers on each date the Sellers request any purchase under this Agreement or
deliver any information to the Buyers. The Sellers will promptly deliver to the
Buyers such information relating to this representation and warranty as the
Buyers request from time to time.

     terminated, whereupon the Contract Purchase Commitment shall terminate, and
     (B) demand that each Seller pay into the Holding Account an amount equal to
     its Individual Repurchase Commitment Amount as of such date. If a Seller
     makes any deposit in the Holding Account, then, upon any reduction in the
     aggregate unpaid principal amount of all outstanding Buyers' Contracts
     purchased from that Seller resulting from (y) the Buyers' receipt of
     principal payments thereon or (z) that Seller's repurchase thereof, the
     Buyer shall withdraw from the Holding Account the amount (if any) by which
     the amount on deposit in the Holding Account exceeds such aggregate unpaid
     principal amount plus accrued, unpaid interest thereon at the Buyer's Rate,
     and pay such amount to that Seller.

          11.2(b) Upon the occurrence of any Termination Event:

          Buyers' Contracts to one or more Obligors and may, in the Agent's
          name, in the Buyers' name or in the Related Seller's name, demand, sue
          for, collect or receive any money or property at any time payable or
          receivable on account of,


                                       48
<PAGE>

          or securing, any of the Buyers' Contracts or the Related Security or
          grant any extension to, make any compromise or settlement with or
          otherwise agree to waive, modify, amend or change the obligation of
          any Obligor. If any payments on any of the Buyers' Contracts or the
          Related Security are received by a Seller after a Termination Event
          has occurred, such payments shall be held in trust by that Seller as
          the property of the Buyers and shall not be commingled with any funds
          or property of that Seller and shall be forthwith remitted to the
          Agent for the benefit of the Buyers;

               (iii) the Agent may require each Seller to, and each Seller
          hereby agrees that it will, at its expense and upon request of the
          Agent forthwith, assemble all of the Contracts, Related Security
          Documents and records related thereto (to the extent not already in
          the Agent's possession) as directed by the Agent and make them
          available to the Agent at a place or places to be designated by the
          Agent; and

               (iv) the Agent may exercise or enforce any and all other rights
          or remedies available by law or agreement against the Buyers'
          Contracts and the Related Security, against a Seller (including under
          the Guaranties), or against any other Person or property.

     If notice to a Seller of any intended disposition of the Contracts and the
     Related Security or any other intended action is required by law in a
     particular instance, such notice shall be deemed commercially reasonable if
     given in the manner specified for the giving of notice in Section 13.3 at
     least ten calendar days prior to the date of intended disposition or other
     action. In addition to the other remedies set forth in this Section 11.2,
     upon the occurrence of any Termination Event and thereafter while the same
     be continuing, each Seller hereby irrevocably authorizes each Buyer to set
     off any obligations of that Seller hereunder to such Buyer, or to make
     deposits into the Holding Account, against all deposits and credits of that
     Seller with, and any and all claims of that Seller against, such Buyer.
     Such right shall exist whether or not such Buyer shall have made any demand
     hereunder, whether or not the deposits and credits held for the account of
     that Seller is or are matured or unmatured, and regardless of the existence
     or adequacy of any security, right or remedy available to such Buyer. Each
     Buyer agrees that, as promptly as is reasonably possible after the exercise
     of any such setoff right, it shall notify the affected Seller of its
     exercise of such setoff right; provided, however, that the failure of a
     Buyer to provide such notice shall not affect the validity of the exercise
     of such setoff rights.

                             CHANGE IN CIRCUMSTANCES

     Section 12.1. Increased Costs. If, as a result of any law, rule,
regulation, treaty or directive, or any change therein or in the interpretation
or administration thereof, or compliance by a Buyer with any request or
directive (whether or not having the force of law) from any court, central bank,
governmental authority, agency or instrumentality, or comparable agency:

          (a) any tax, duty or other charge with respect to the Buyers'
     Contracts or the Buyers' obligation to purchase Contracts is imposed,
     modified or deemed applicable, or the basis of taxation of payments to any
     Buyer of interest or principal on the Contracts or any amounts due under
     this Agreement (other than taxes imposed on the overall net income of a
     Buyer by the United States and the jurisdiction in which the Buyer has its
     principal office) is changed;

          (b) any reserve, special deposit, special assessment or similar
     requirement against assets of, deposits with or for the account of, or
     credit extended by, any Buyer is imposed, modified or deemed applicable; or

          (c) any other condition affecting this Agreement, the Buyers'
     Contracts or the Buyers' obligation to purchase the Contracts is imposed on
     any Buyer or the relevant funding markets;

and any Buyer determines that, by reason thereof, the cost to that Buyer of
purchasing or maintaining the Contracts or the Buyers' obligation to purchase
Contracts is increased, or the amount of any sum receivable by that Buyer
hereunder or under this Agreement or any Contract is reduced;

then, PDC shall pay to such Buyer upon demand by such Buyer (with a copy to the
Agent) such additional amount or amounts as will compensate such Buyer (or the
controlling Person in the instance of (c) above) for such additional costs or
reduction (provided that the Buyer has not been compensated for such additional
cost or reduction in the calculation of the Eurodollar Reserve Rate). Each Buyer
will promptly notify PDC of any event of which such Buyer has knowledge,
occurring after the date hereof, which will entitle such Buyer to compensation
pursuant to this Section. If a Buyer fails to give such notice within 45 days
after it obtains knowledge of such an event, such Buyer shall, with respect to
compensation payable pursuant to this Section, only be entitled to payment under
this Section for costs incurred from and after the date 45 days prior to the
date that such Buyer does give such notice. A certificate of a Buyer claiming
compensation under this Section, setting forth the additional amount or amounts
to be paid to it hereunder and stating in reasonable detail the basis for the
charge and the method of computation, shall be conclusive in the absence of
manifest error. In determining such amount, each Buyer may use any reasonable
averaging and attribution methods. Failure on the part of a Buyer to demand
compensation for any increased costs or reduction in amounts received or
receivable with respect to any Interest Period shall not constitute a waiver of
that Buyer's rights to demand compensation for any


                                       50
<PAGE>

increased costs or reduction in amounts received or receivable in any subsequent
Interest Period (subject to the limitation contained in the third preceding
sentence).

     Section 12.2. Deposits Unavailable or Interest Rate Unascertainable or
Inadequate; Impracticability. If any Buyer reasonably determines (which
determination shall be conclusive and binding on the parties hereto) that:

          (a) deposits of the necessary amount for the relevant Interest Period
     or Fixed Rate Period elected by PDC pursuant to Section 2.7 are not
     available to that Buyer in the relevant markets or that, by reason of
     circumstances affecting such market, adequate and reasonable means do not
     exist for ascertaining the Eurodollar Rate for such Interest Period or
     Fixed Rate Period;

          (b) the use of the Eurodollar Rate (Reserve Adjusted) as the basis for
     the Buyers' Rate will not adequately and fairly reflect the cost to that
     Buyer of purchasing or maintaining the Buyers' Contracts for a relevant
     Interest Period or Fixed Rate Period; or

          (c) the use of the Eurodollar Rate (Reserve Adjusted) as the basis for
     the Buyers' Rate has become impracticable as a result of any event
     occurring after the date of this Agreement which, in the opinion of that
     Buyer, materially and adversely affects the Buyers' Contracts or the
     Buyers' obligation to purchase Contracts or the relevant market;

such Buyer shall promptly give notice of such determination to PDC, with a copy
to the Agent, and the Buyers' Rate with respect to the Buyer's Percentage of
that Buyer of the principal amount outstanding under the Buyers' Contracts shall
be the Reference Rate for as long as such condition persists; provided, however,
that if at the time of any such determination the affected Buyer is using a
reserve-adjusted certificate of deposit rate or similar rate as a basis for
pricing, and if PDC so requests and enters into such amendments to this
Agreement as the Agent and the Buyers may reasonably request in order to
incorporate appropriate definitions and other terms typically included in the
affected Buyer's documentation with respect to such rates, then the Buyers' Rate
for the Buyer's Percentage of the affected Buyer of the Buyers' Contracts shall
be the sum of (i) such reserve-adjusted certificate of deposit or similar rate,
(ii) the Applicable Margin, and (iii) one eighth of one percent (0.125%).

     Section 12.3. Illegality. If at any time due to the adoption of any law,
rule, regulation, treaty or directive, or any change therein or in the
interpretation or administration thereof by any court, central bank,
governmental authority, agency or instrumentality, or comparable agency charged
with the interpretation or administration thereof, or for any other reason
arising subsequent to the date of this Agreement, it shall become unlawful or
impossible for a Buyer to purchase Contracts at a rate based on the Eurodollar
Rate (Reserve


                                       51
<PAGE>

Adjusted), the obligation of such Buyer to purchase Contracts shall, upon the
happening of such event, forthwith be suspended for the duration of such
illegality or impossibility. If any such event shall make it unlawful or
impossible for a Buyer to maintain any Buyers' Contracts previously purchased by
it hereunder, such Buyer shall, upon the happening of such event, notify PDC
thereof in writing, and the Buyers' Rate with respect to the Buyer's Percentage
of that Buyer of the principal amount outstanding under the Buyers' Contracts
shall thereafter be the Reference Rate.

     Section 12.4. Capital Adequacy. In the event that any change in any law,
rule, regulation, treaty or directive, or any change therein or in the
interpretation or administration thereof by any court, central bank,
governmental authority, agency or instrumentality, or comparable agency (a
"Governmental Agency") charged with the interpretation or administration
thereof, or compliance by any Bank with any request or directive (whether or not
having the force of law) of any such Governmental Agency, reduces or shall have
the effect of reducing the rate of return on any Buyer's capital or the capital
of its parent corporation (by an amount such Buyer deems material) as a
consequence of its Individual Contract Purchase Commitment Amount and/or its
undivided percentage ownership interest in the Buyers' Contracts to a level
below that which such Buyer or its parent corporation could have achieved but
for such change (taking into account such Buyer's policies and the policies of
its parent corporation with respect to capital adequacy), then PDC shall, within
30 days after written notice and demand from such Buyer (with a copy to the
Agent), pay to such Buyer additional amounts sufficient to compensate such Buyer
or its parent corporation for such reduction. Any determination by such Buyer
under this Section and any certificate as to the amount of such reduction given
to PDC by such Buyer shall be final, conclusive and binding for all purposes,
absent error. Each Buyer will promptly notify PDC of any event of which such
Buyer has knowledge, occurring after the date hereof, which will entitle such
Buyer to compensation pursuant to this Section. If a Buyer fails to give such
notice within 45 days after it obtains knowledge of such an event, such Buyer
shall, with respect to compensation payable pursuant to this Section, only be
entitled to payment under this Section for costs incurred from and after the
date 45 days prior to the date that such Buyer does give such notice.

                                  MISCELLANEOUS

     Section 13.1. Waiver and Amendment. No failure on the part of the Agent or
any Buyer to exercise and no delay in exercising any power or right hereunder or
under any Assignment shall operate as a waiver thereof; nor shall any single or
partial exercise of any power or right preclude any other or further exercise
thereof or the exercise of any other power or right. The remedies herein and in
any other instrument, document or agreement delivered or to be delivered to the
Agent or the Buyers hereunder or in connection herewith are cumulative and not
exclusive of any remedies provided by law. No notice to or demand on a Seller
not required hereunder or under an Assignment shall in any event entitle either


                                       52
<PAGE>

Seller to any other or further notice or demand in similar or other
circumstances or constitute a waiver of the right of the Agent or the Buyers to
any other or further action in any circumstances without notice or demand. No
amendment, modification or waiver of any provision of this Agreement or consent
to any departure by a Seller therefrom shall be effective unless the same shall
be in writing and signed by the Agent and the Majority Buyers, and then such
amendment, modifications, waiver or consent shall be effective only in the
specific instances and for the specific purpose for which given. Notwithstanding
the foregoing, no such amendment, modification, waiver or consent shall:

          13.1(a) Reduce the rate or extend the time of payment of interest
     thereon, or reduce the amount of the principal thereof, modify any of the
     provisions of any Buyers' Contract with respect to the payment or repayment
     thereof, release any Guaranty, modify any repurchase or other payment
     obligation of the Sellers, or transfer title to (or release any security
     interest that the Agent may be deemed to hold, pursuant to Section 2.6, in)
     any Buyers' Contract, without the consent of each Buyer; or

          13.1(b) Increase the amount or extend the time of any Individual
     Contract Purchase Commitment Amount of any Buyer, without the consent of
     such Buyer; or

          13.1(c) Reduce the rate or extend the time of payment of any fee
     payable to a Buyer, without the consent of the Buyer affected; or

          13.1(d) Amend the definition of Majority Buyers or otherwise reduce
     the percentage of the Buyers required to approve or effectuate any such
     amendment, modification, waiver, or consent, without the consent of all the
     Buyers; or

          13.1(e) Amend any of the foregoing Sections 13.1 (a) through (d) or
     this Section 13.1 (e) without the consent of all the Buyers; or

          13.1(f) Amend any provision of this Agreement relating to the Agent in
     its capacity as Agent without the consent of the Agent.

     Section 13.2. Expenses. Whether or not any Contract is purchased hereunder,
the Sellers jointly and severally agree to reimburse the Agent upon demand for
all reasonable expenses paid or incurred by the Agent (including filing and
recording costs and fees and expenses of legal counsel, who may be employees of
the Agent) in connection with the preparation, negotiation, execution, delivery,
amendment, modification and interpretation of this Agreement, the Assignments
and the Guaranties. The Sellers also jointly and severally agree to reimburse
the Agent and each Buyer upon demand for all reasonable out-of-pocket expenses
(including expenses of legal counsel) paid or incurred by the Agent or any Buyer
in connection with the collection and enforcement of this Agreement, the
Assignments, the Guaranties, the Buyers' Contracts and the Related Security
Documents. The Sellers jointly


                                       53
<PAGE>

and severally agree to indemnify and hold the Agent and the Buyers harmless from
any loss or expense which may arise or be created by the acceptance of
telephonic or other instructions for purchasing Contracts or disbursing the
proceeds thereof. The obligations of the Sellers under this Section 13.2 shall
survive any termination of this Agreement.

     Section 13.3. Notices. Except when telephonic notice is expressly
authorized by this Agreement, any notice or other communication to any party in
connection with this Agreement shall be in writing and shall be sent by manual
delivery, telegram, telex, facsimile transmission, overnight courier or United
States mail (postage prepaid) addressed to such party at the address specified
on the signature page hereof, or at such other address as such party shall have
specified to the other party hereto in writing. All periods of notice shall be
measured from the date of delivery thereof if manually delivered, from the date
of sending thereof if sent by telegram, telex or facsimile transmission, from
the first Business Day after the date of sending if sent by overnight courier,
or from four days after the date of mailing if mailed; provided, however, that
any notice to the Agent or any Buyer under Article II hereof shall be deemed to
have been given only when received by the Agent or that Buyer.

     Section 13.4. Successors and Assigns; Disposition of Interests in Buyers'
Contracts; Transferees.

          13.4(a) This Agreement shall be binding upon and inure to the benefit
     of the Sellers, the Buyers, the Agent, and their respective successors and
     assigns, except that the Sellers may not assign or transfer any of their
     rights or obligations under this Agreement without the prior written
     consent of each Buyer.

          13.4(b) Any Buyer may, in the ordinary course of its business and in
     accordance with applicable law, at any time sell to one or more banks or
     other entities ("Participants") participating interests in such Buyer's
     undivided percentage ownership interest in the Buyers' Contracts, and the
     Individual Contract Purchase Commitment Amount of such Buyer, or any other
     interest of such Buyer hereunder. In the event of any such sale by a Buyer
     of participating interests to a Participant, (i) such Buyer's obligations
     under this Agreement to the other parties to this Agreement shall remain
     unchanged, (ii) such Buyer shall remain solely responsible for the
     performance thereof, (iii) such Buyer shall remain the owner of such
     Buyer's undivided percentage ownership interest in the Buyers' Contracts
     for all purposes under this Agreement, (iv) the Sellers and the Agent shall
     continue to deal solely and directly with such Buyer in connection with
     such Buyer's rights and obligations under this Agreement and (v) the
     agreement pursuant to which such Participant acquires its participating
     interest herein shall provide that such Buyer shall retain the sole right
     and responsibility to enforce its rights hereunder and with respect to the
     Buyers' Contracts, including, without limitation the right to consent or
     agree to any amendment, modification, consent or waiver with respect to
     this Agreement or any other Buyers' Contract, provided that such agreement
     may provide that such Buyer


                                       54
<PAGE>

     will not consent or agree to any such amendment, modification, consent or
     waiver with respect to the matters set forth in Sections 13.1(a) - (c)
     without the prior consent of such Participant. The Sellers agree that if
     amounts outstanding under this Agreement are due and unpaid, or shall have
     been declared or shall have become due and payable upon the occurrence of a
     Termination Event, each Participant shall be deemed to have, to the extent
     permitted by applicable law, the right of setoff in respect of its
     participating interest in amounts owing under this Agreement to the same
     extent as if the amount of its participating interest were owing directly
     to it as a Buyer under this Agreement; provided, that such right of setoff
     shall be subject to the obligation of such Participant to share with the
     Buyers, and the Buyers agree to share with such Participant, as provided in
     subsection 14.11. The Sellers also agree that each Participant shall be
     entitled to the benefits of subsections 10.20, 11.2(b)(v), 12.1, 12.2, 12.3
     and 13.2 with respect to its participation in the Commitments and Loans;
     provided, that no Participant shall be entitled to receive any greater
     amount pursuant to such subsections than the transferor Buyer would have
     been entitled to receive in respect of the amount of the participation
     transferred by such transferor Buyer to such Participant had no such
     transfer occurred.

          13.4(c) Each Buyer may, from time to time, with the consent of the
     Agent (which consent shall not be unreasonably withheld), assign to other
     Persons ("Assignees") part of such Buyer's undivided percentage ownership
     interest in the Buyers' Contracts, together with equivalent proportions of
     its Individual Contract Purchase Commitment Amount and its Buyer's
     Percentage, and of such Buyer's "Loans" and "Commitment" (as defined in the
     Credit Agreement) pursuant to written agreements executed by such assigning
     Buyer, such Assignee(s) and the Agent in substantially the form of Exhibit
     I, which agreements shall specify in each instance the portion of the
     Buyer's Percentage and its undivided percentage ownership interest in the
     Buyers' Contracts which is to be assigned to each Assignee and the portion
     of the Individual Contract Purchase Commitment Amount of such Buyer to be
     assumed by each Assignee (each, an "Assignment Agreement"); provided,
     however, that the assigning Buyer must pay to the Agent a processing and
     recordation fee of $3,500 and that each Assignment must be for an aggregate
     amount of $15,000,000 or more (or the entire amount of the assigning
     Buyer's Individual Contract Purchase Commitment Amount, if lesser). Upon
     the execution of each Assignment Agreement by the assigning Buyer, the
     relevant Assignee, the Sellers and the Agent, payment to the assigning
     Buyer by such Assignee of the purchase price for the portion of the
     assigning Buyer's undivided percentage ownership interest in the Buyers'
     Contracts being acquired by the Assignee and receipt by the Sellers of a
     copy of the relevant Assignment Agreement, (x) such Assignee lender shall
     thereupon become a "Buyer" for all purposes of this Agreement with an
     Individual Contract Purchase Commitment Amount in the amount set forth in
     such Assignment Agreement and with all the rights, powers and obligations
     afforded a Buyer under this Agreement, (y) such assigning Buyer shall have
     no further liability for funding the portion of its Individual


                                       55
<PAGE>

     Contract Purchase Commitment Amount assumed by such Assignee and (z) the
     address for notices to such Assignee shall be as specified in the
     Assignment Agreement executed by it.

          13.4(d) The Sellers shall not be liable for any costs incurred by the
     Buyers in effecting any participation or assignment.

          13.4(e) Each Buyer may disclose to any Assignee or Participant and to
     any prospective Assignee or Participant any and all financial information
     in such Buyer's possession concerning the Sellers or any of their
     Subsidiaries which has been delivered to such Buyer by or on behalf of the
     Sellers or any of their Subsidiaries pursuant to this Agreement or which
     has been delivered to such Buyer by or on behalf of the Sellers or any of
     its Subsidiaries in connection with such Buyer's credit evaluation of the
     Sellers or any of their Subsidiaries prior to entering into this Agreement,
     provided that prior to disclosing such information, such Buyer shall first
     obtain the agreement of such prospective Assignee or Participant to comply
     with the provisions of Section 13.13.

     Section 13.5. Severability. Any provision of this Agreement or any
Assignment which is prohibited or unenforceable in any jurisdiction shall, as to
such jurisdiction, be ineffective to the extent of such prohibition or
unenforceability without invalidating the remaining provisions hereof or
affecting the validity or enforceability of such provision in any other
jurisdiction.

     Section 13.6. Subsidiary References. The provisions of this Agreement
relating to Subsidiaries shall apply only during such times as the Seller has
one or more Subsidiaries.

     Section 13.7. Captions. The captions or headings herein and any table of
contents hereto are for convenience only and in no way define, limit or describe
the scope or intent of any provision of this Agreement.

     Section 13.8. Entire Agreement. This Agreement, the Guaranties and the
Assignments embody the entire agreement and understanding between the Sellers,
the Agent and the Buyers with respect to the subject matter hereof and thereof.
This Agreement, the Guaranties and the Assignments supersede all prior
agreements and understandings relating to the subject matter hereof.

     Section 13.9. Counterparts. This Agreement may be executed in any number of
counterparts, all of which taken together shall constitute one and the same
instrument, and either of the parties hereto may execute this Agreement by
signing any such counterpart.

     Section 13.10. Governing Law. THE VALIDITY, CONSTRUCTION AND ENFORCEABILITY
OF THIS AGREEMENT AND THE NOTE SHALL BE GOVERNED


                                       56
<PAGE>

BY THE INTERNAL LAWS OF THE STATE OF MINNESOTA, WITHOUT GIVING EFFECT TO
CONFLICT OF LAWS PRINCIPLES THEREOF, BUT GIVING EFFECT TO FEDERAL LAWS OF THE
UNITED STATES APPLICABLE TO NATIONAL BANKS.

     Section 13.11. Consent to Jurisdiction. AT THE OPTION OF THE AGENT, THIS
AGREEMENT AND THE ASSIGNMENTS MAY BE ENFORCED IN ANY FEDERAL COURT OR MINNESOTA
STATE COURT SITTING IN MINNEAPOLIS OR ST. PAUL, MINNESOTA; AND THE SELLERS
CONSENT TO THE JURISDICTION AND VENUE OF ANY SUCH COURT AND WAIVE ANY ARGUMENT
THAT VENUE IN SUCH FORUMS IS NOT CONVENIENT. IN THE EVENT A SELLER COMMENCES ANY
ACTION IN ANOTHER JURISDICTION OR VENUE UNDER ANY TORT OR CONTRACT THEORY
ARISING DIRECTLY OR INDIRECTLY FROM THE RELATIONSHIP CREATED BY THIS AGREEMENT,
THE AGENT AT ITS OPTION SHALL BE ENTITLED TO HAVE THE CASE TRANSFERRED TO ONE OF
THE JURISDICTIONS AND VENUES ABOVE-DESCRIBED, OR IF SUCH TRANSFER CANNOT BE
ACCOMPLISHED UNDER APPLICABLE LAW, TO HAVE SUCH CASE DISMISSED WITHOUT
PREJUDICE.

     Section 13.12. Waiver of Jury Trial. EACH OF THE SELLERS, THE AGENT AND THE
BUYERS IRREVOCABLY WAIVES ANY RIGHT TO A TRIAL BY JURY IN ANY ACTION OR
PROCEEDING TO ENFORCE OR DEFEND ANY RIGHTS (a) UNDER THIS AGREEMENT OR UNDER ANY
AMENDMENT, INSTRUMENT, DOCUMENT OR AGREEMENT DELIVERED OR WHICH MAY IN THE
FUTURE BE DELIVERED IN CONNECTION HEREWITH OR (b) ARISING FROM ANY RELATIONSHIP
EXISTING IN CONNECTION WITH THIS AGREEMENT, AND AGREES THAT ANY SUCH ACTION OR
PROCEEDING SHALL BE TRIED BEFORE A COURT AND NOT BEFORE A JURY.

     Section 13.13. Confidentiality of Information. The Agent and the Buyers
shall use reasonable efforts to assure that information about the Sellers and
their operations, affairs and financial condition, not generally disclosed to
the public or to trade and other creditors, which is furnished to the Agent or
the Buyers pursuant to the provisions hereof is used only for the purposes of
this Agreement and any other relationship between the Agent or a Buyer and the
Sellers and shall not be divulged to any Person other than the Agents, the
Buyers, their Affiliates and their respective officers, directors, employees and
agents, except: (a) to their attorneys and accountants, (b) in connection with
the enforcement of the rights of the Agent or the Buyer hereunder or otherwise
in connection with applicable litigation, (c) in connection with assignments and
participations and the solicitation of prospective assignees and participants
referred to in Section 13.4 and (d) as may otherwise be required or requested by
any regulatory authority having jurisdiction over the Agent or a Buyer or by any
applicable law, rule, regulation or judicial process, the opinion of the Agent's
or Buyer's counsel concerning the making of such disclosure to be binding on the
parties hereto. The Agent and


                                       57
<PAGE>

the Buyers shall not incur any liability to the Sellers by reason of any
disclosure permitted by this Section 13.13.

     Section 13.14. Survival of Agreement. All representations, warranties,
covenants and agreement made by the Sellers herein and in the certificates or
other instruments prepared or delivered in connection with or pursuant to this
Agreement shall be deemed to have been relied upon by the Agent and the Buyers,
regardless of any investigation made by or on behalf of the Agent or the Buyers,
and shall continue in full force and effect as long as any Contract is
outstanding and unpaid and so long as the Contract Purchase Commitment has not
been terminated; provided, however, that the obligations of the Sellers under
Sections 10.20 and 13.2 shall survive payment in full of the Contracts and the
termination of the Contract Purchase Commitment.

     Section 13.15 Withholding Taxes.

          (a) Buyers to Submit Forms. Each Buyer represents to the Sellers and
     the Agent that, as of the date it becomes a Buyer and at all times
     thereafter, it is either (i) a corporation organized under the laws of the
     United States or any State thereof or (ii) entitled to complete exemption
     from United States withholding tax imposed on or with respect to any
     payments, including fees, to be made pursuant to this Agreement (x) under
     an applicable provision of a tax convention to which the United States is a
     party or (y) because it is acting through a branch, agency or office in the
     United States and any payment to be received by it hereunder is effectively
     connected with a trade or business in the United States. Each Buyer that is
     not a United States person (as such term is defined in Section 7701(a)(30)
     of the Code) shall submit to the Sellers and the Agent, on or before the
     later of the date hereof or the day on which such Buyer becomes a Buyer,
     duly completed and signed copies of either Form 1001 (relating to such
     Buyer and entitling it to a complete exemption from withholding on all
     payments to be received by such Buyer hereunder) or Form 4224 (relating to
     all payments to be received by such Buyer hereunder) of the United States
     Internal Revenue Service. Thereafter and from time to time, each such Buyer
     shall submit to the Sellers and the Agent such additional duly completed
     and signed copies of one or the other of such Forms (or such successor
     Forms as shall be adopted from time to time by the relevant United States
     taxing authorities) as may be (i) reasonably requested by the Sellers or
     the Agent and (ii) required and permitted under then- current United States
     law or regulations to avoid United States withholding taxes on payments in
     respect of all payments to be received by such Buyer hereunder. Upon the
     request of the Sellers or the Agent, each Buyer that is a United States
     person (as such term is defined in Section 7701(a)(30) of the Code) shall
     submit to the Sellers and the Agent a certificate in such form as is
     reasonably satisfactory to the Sellers and the Agent to the effect that it
     is such a United States person.

          (b) Inability of a Buyer. If any Buyer that is not a United States
     person (as such term is defined in Section 7701(a)(30) of the Code)
     determines that, as a result of any change in law or regulation or the
     interpretation thereof, any Seller or Obligor, or the Agent, is required by
     law or regulation to make any deduction, withholding or backup withholding
     (in which case either Seller or the Agent is hereby authorized to make such
     deduction, withholding or backup withholding) of any taxes, levies,
     imposts, duties, fees, liabilities or similar charges of the United States
     of America, any possession or territory of the United States of America
     (including the Commonwealth of Puerto Rico) or any area subject to the
     jurisdiction of the United States of America ("U.S. Taxes") from any
     payments to a Buyer pursuant to this Agreement in respect of the
     obligations payable to such Buyer then or thereafter outstanding under this
     Agreement or any Buyers' Contract, the Sellers will pay to such Buyer an
     amount which, after deduction from such increased amount of all U.S. Taxes
     required to be withheld or deducted therefrom, will yield the amount
     required under this Agreement or the Buyers' Contract to be paid with
     respect thereto; provided, that the Sellers shall not be required to pay
     any additional amount pursuant to this Section 13.15(b) to any Buyer (i)
     that is not, either on the date this Agreement is executed by such Buyer or
     on the date such Buyer becomes such under Section 13.4(c), either (x)
     entitled to submit Form 1001 (relating to such Buyer and entitling it to a
     complete exemption from withholding on all payments to be received by such
     Buyer hereunder) or Form 4224 (relating to all payments to be received by
     such Buyer hereunder) or (y) a United States person (as such term is
     defined in Section 7701(a)(30) of the Code), or (ii) that has failed to
     submit any form or certificate that it was required to file pursuant to
     subsection (a) and entitled to file under applicable law or (iii) arising
     from such Buyer's failure to comply with any certification, identification
     or other similar requirement under United States income tax laws or
     regulations (including backup withholding) to establish entitlement to
     exemption from such U.S. Taxes; and provided, further, that if a Buyer, as
     a result of any amount paid by the Sellers to such Buyer pursuant to this
     Section 13.15, shall realize a tax credit or refund, which tax credit or
     refund would not have been realized but for the Sellers' payment of such
     amount, such Buyer shall pay to the Sellers an amount equal to such tax
     credit or refund. Each Buyer may determine the portion, if any, of any tax
     credit or refund attributable to the Sellers' payments using such
     attribution and accounting methods as such Buyer reasonably selects, and
     such Buyer's determination of the portion of any tax credit or refund
     attributable to the Sellers' payments shall be conclusive in the absence of
     manifest error. The obligation of the Sellers under this Section 13.15(b)
     shall survive the payment in full of the Obligations and the termination of
     the Commitments of such Buyer.

          (c) Substitution of Buyer. In the event the Sellers are required
     pursuant to this Section 13.15 to pay any additional amount to any Buyer,
     such Buyer shall, if no Event of Default has occurred and is continuing,
     upon the request of the Sellers to such Buyer and the Agent, assign,
     pursuant to and in accordance with the provisions


                                       59
<PAGE>

     of Section 13.4, all of its rights and obligations under this Agreement and
     with respect to the Buyers' Contracts to another Buyer or an assignee
     selected by the Sellers and reasonably satisfactory to the Agent, in
     consideration for (i) the payment by such assignee to the assigning Buyer
     of the Buyer's Percentage of the assigning Buyer of the principal
     outstanding under, and interest accrued at the Buyers' Rate on, the Buyers'
     Contracts, (ii) the payment by the Sellers to the assigning Buyer of any
     and all other amounts owing to such Buyer under any provision of this
     Agreement accrued and unpaid to the date of such assignment and (iii) the
     Sellers' release of the assigning Buyer from any further obligation or
     liability under this Agreement. Notwithstanding anything to the contrary in
     this Section 13.15(c), in no event shall the replacement of any Buyer
     result in a decrease in the aggregate Contract Purchase Commitments without
     the written consent of the Majority Buyers.


                                   ARTICLE XIV
                                   -----------
                                    THE AGENT

     The following provisions shall govern the relationship of the Agent with
the Buyers.

     Section 14.1 Appointment and Authorization. Each Buyer appoints and
authorizes the Agent to take such action as agent on its behalf and to exercise
such respective powers under this Agreement and with respect to the Buyers'
Contracts as are delegated to the Agent by the terms thereof, together with such
powers as are reasonably incidental thereto. Neither the Agent nor any of its
directors, officers or employees shall be liable for any action taken or omitted
to be taken by it under or in connection with this Agreement and with respect to
the Buyers' Contracts, except for its own gross negligence or willful
misconduct. The Agent shall act as an independent contractor in performing its
obligations as Agent hereunder and nothing herein contained shall be deemed to
create any fiduciary relationship among or between the Agent, the Sellers or the
Buyers.

     Section 14.2 Buyers. The Agent may treat each Buyer as the owner of its
respective Buyer's Percentage until written notice of transfer shall have been
filed with it, signed by such Buyer and in the form of Exhibit I.

     Section 14.3 Consultation With Counsel. The Agent may consult with legal
counsel selected by it and shall not be liable for any action taken or suffered
in good faith by it in accordance with the advice of such counsel.

     Section 14.4 Validity of Agreement and Buyers' Contracts. The Agent shall
not be under a duty to examine or pass upon the validity, effectiveness,
genuineness or value of any of this Agreement or the Buyers' Contracts or any
other instrument or document furnished pursuant thereto, and the Agent shall be
entitled to assume that the same are valid, effective and genuine and what they
purport to be.


                                       60

     Section 14.5 U.S. Bank and Affiliates. With respect to its Individual
Contract Purchase Commitment Amount and the undivided percentage ownership
interest in the Buyers' Contracts purchased by it, U.S. Bank shall have the same
rights and powers under this Agreement and with respect to the Buyers' Contracts
as any other Buyer and may exercise the same as though it were not the Agent
consistent with the terms thereof, and U.S. Bank and its Affiliates may accept
deposits from, lend money to and generally engage in any kind of business with
the Sellers as if it were not the Agent.

     Section 14.6 Action by Agent. Except as may otherwise be expressly stated
in this Agreement, the Agent shall be entitled to use its discretion with
respect to exercising or refraining from exercising any rights which may be
vested in it by, or with respect to taking or refraining from taking any action
or actions which it may be able to take under or in respect of, this Agreement
and the Buyers' Contracts. The Agent shall be required to act or to refrain from
acting (and shall be fully protected in so acting or refraining from acting)
upon the instructions of the Majority Buyers, and such instructions shall be
binding upon all owners of undivided percentage ownership interests in the
Buyers' Contracts; provided, however, that the Agent shall not be required to
take any action which exposes the Agent to personal liability or which is
contrary to this Agreement, the Buyers' Contracts or applicable law. The Agent
shall incur no liability under or in respect of any of this Agreement or the
Buyers' Contracts by acting upon any notice, consent, certificate, warranty or
other paper or instrument believed by it to be genuine or authentic or to be
signed by the proper party or parties and to be consistent with the terms of
this Agreement.

     Section 14.7 Credit Analysis. Each Buyer has made, and shall continue to
make, its own independent investigation or evaluation of the operations,
business, property and condition, financial and otherwise, of the Sellers in
connection with entering into this Agreement and has made its own appraisal of
the creditworthiness of the Sellers. Except as explicitly provided herein, the
Agent has no duty or responsibility, either initially or on a continuing basis,
to provide any Buyer with any credit or other information with respect to such
operations, business, property, condition or creditworthiness, whether such
information comes into its possession on or before the first Termination Event
or at any time thereafter.

     Section 14.8 Notices of Termination Event, Etc. In the event that the Agent
shall have acquired actual knowledge of any Termination Event or Unmatured
Termination Event, the Agent shall promptly give notice thereof to the Buyers.

     Section 14.9 Indemnification. Each Buyer agrees to indemnify the Agent, as
Agent (to the extent not reimbursed by the Sellers), ratably according to such
Buyer's Individual Contract Purchase Commitment Amount, from and against any and
all liabilities, obligations, losses, damages, penalties, actions, judgments,
suits, costs, expenses or disbursements of any kind or nature whatsoever which
may be imposed on or incurred by the Agent in any way relating to or arising out
of this Agreement or the Buyers' Contracts or any action taken or omitted by the
Agent under this Agreement or with respect to the Buyers' Contracts, provided


                                       61
<PAGE>

that no Buyer shall be liable for any portion of such liabilities, obligations,
losses, damages, penalties, actions, judgments, suits, costs, expenses or
disbursements resulting from the Agent's gross negligence or willful misconduct.
No payment by any Buyer under this Section shall relieve the Sellers of any of
their obligations under this Agreement.

     Section 14.10 Payments and Collections. All funds received by the Agent in
respect of any payments made by the Sellers under this Agreement shall be
distributed forthwith by the Agent among the Buyers, in like currency and funds
as received, ratably according to each Bank's Individual Contract Purchase
Commitment Amount. After any Event of Default has occurred, all funds received
by the Agent, whether as payments by the Sellers or as realization on any
collateral or on any guaranties, shall (except as may otherwise be required by
law) be distributed by the Agent in the following order: (a) first to the Agent
or any Buyer who has incurred unreimbursed costs of collection with respect to
any amount payable hereunder, ratably to the Agent and each Buyer in the
proportion that the costs incurred by the Agent or such Buyer bear to the total
of all such costs incurred by the Agent and all Buyers; (b) next to the Agent
for the account of the Buyers (in accordance with their respective Individual
Contract Purchase Commitment Amounts) for application on the amounts owing
hereunder; and (c) last to the Agent for application to any unpaid agent's fees.

     Section 14.11 Sharing of Payments. If any Buyer shall receive and retain
any payment, voluntary or involuntary, whether by setoff, application of deposit
balance or security, or otherwise, in respect of Indebtedness under this
Agreement in excess of such Buyer's share thereof as determined under this
Agreement, then such Buyer shall purchase from the other Buyers for cash and at
face value and without recourse, such participation in the percentage ownership
interests in the Buyers' Contracts held by such other Buyers as shall be
necessary to cause such excess payment to be shared ratably as aforesaid with
such other Buyers; provided, that if such excess payment or part thereof is
thereafter recovered from such purchasing Buyer, the related purchases from the
other Buyers shall be rescinded ratably and the purchase price restored as to
the portion of such excess payment so recovered, but without interest. Subject
to the participation purchase obligation above, each Buyer agrees to exercise
any and all rights of setoff, counterclaim or banker's lien first fully against
any indebtedness of the Sellers to such Buyer arising under or pursuant to this
Agreement or the Credit Agreement and to any participations held by such Buyer
in indebtedness of the Sellers arising under or pursuant to this Agreement and
the Credit Agreement, and only then to any other indebtedness of the Sellers to
such Buyer.

     Section 14.12 Advice to Buyers. The Agent shall forward to the Buyers
copies of all notices, financial reports and other communications received
hereunder from the Sellers by it as Agent, excluding, however, notices, reports
and communications which by the terms hereof are to be furnished by the Sellers
directly to each Buyer.

     Section 14.13 Resignation. If at any time U.S. Bank shall deem it
advisable, in its sole discretion, it may submit to each of the Buyers and the
Sellers a written notification of


                                       62
<PAGE>

its resignation as Agent under this Agreement, such resignation to be effective
upon the appointment of a successor Agent, but in no event later than 30 days
from the date of such notice. Upon submission of such notice, the Majority
Buyers may appoint a successor Agent.
