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 with respect to such Contract, the Related Security Documents with

(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.

                                   ARTICLE III
                            COLLECTIONS AND SERVICING

         Section 3.1 Servicing Agency; Holding of Buyers' Contracts.

         (a) Contract Collections. 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 PDSI or Webster), 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 of
such amounts into immediately available funds as soon as is commercially
reasonable. All such immediately available funds collected by the Servicer shall
be deposited as promptly as practicable (not later than the

                                      -18-



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 National Association under that certain Escrow Agreement dated as of June
20, 1997, as amended by a First Amendment to Escrow Agreement dated as of June
19, 2002, between PDC, PDSI, the Agent and U.S. Bank 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 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.

         (b) Manner of Holding Buyers' Contracts. The Servicer shall hold in
trust, for the benefit of the Agent and the Buyers, the Buyers' Contracts, until
its status as Servicer is terminated as set forth herein. The Servicer shall not
release, deliver, sell, pledge or grant a security interest in or authorize the
release, delivery, sale, pledge or the granting of a security interest in, any
Buyers' Contract to any other entity or person, or take any other action with
respect to any Buyers' Contract which could cause the sale to the Buyers to
become unperfected or which could otherwise jeopardize the perfected sale of any
Buyers' Contract. The Servicer shall physically segregate all Buyers' Contracts
from all other contracts or documents of PDC or
         any Seller, and shall adequately designate such area as an area
containing only Buyers' Contracts. The Servicer shall review Buyers' Contracts
for compliance with the legending requirements set forth in Section 2.2(ii)
hereof. Upon receipt of written notice from the Agent, the Servicer shall
deliver the Buyers' Contracts immediately to the Agent. The Servicer shall not
honor any requests or instructions from any Person other than the Agent relating
to any Buyers' Contract.

         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

                                       -19-



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 Buyers, PDSI or Webster,
as the case may be, shall notify the Obligor that the Servicer is authorized to
service such Contract on behalf of PDSI or Webster, as the case may be. 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

                                       -20-



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.

                                   ARTICLE IV
                                   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 the Servicer is not in default under Section
         4.2, the Servicer may retain any late charges received by the Servicer.

         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
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-

                                       -21-



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
Buyers' 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 the Servicer'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;

                 (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.

                                       -22-



         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.

     matters (i) in which an adverse determination or result could result in the
     revocation of or have a material adverse effect on any operating permits,
     air emission permits, water discharge permits, hazardous waste permits or
     other permits held by PDC, 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 PDC, either
     Seller or such Subsidiary to any Person or which will require a material
     expenditure by PDC, either Seller or such Subsidiary to cure any alleged
     problem or violation.

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

     Section 6.3 Inspection. PDC and each Seller shall permit any Person

the affairs, finances and accounts of such Person's and the Subsidiaries with,

such visits, inspections and examinations made while any Termination Event is
continuing shall be at the expense of the Sellers.

                                   ARTICLE VII
                   SELLERS' OBLIGATION TO REPURCHASE CONTRACTS

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

                                      -28-



     Section 7.1 Sellers' Obligations to Repurchase.

             (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;

                 (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 PDC or that
             Seller.

             (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

                                      -29-



further rights therein and all collections on such repurchased Contract shall be
the sole property of that Seller.

                                  ARTICLE VIII
                PDC'S AND SELLERS' REPRESENTATIONS AND WARRANTIES

     In order to induce the Agent and the Buyers to execute this Agreement and
to purchase Contracts hereunder, PDC and 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 and Webster, 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 enter
into the Transaction Documents executed by it and to perform its obligations
under the Transaction Documents executed by it. PDC and each of its
Subsidiaries, including PDSI and Webster, 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 PDC and the Sellers of the Transaction Documents executed by it
have been duly authorized by all necessary corporate action by PDC and the
Sellers, and the Transaction Documents executed by it constitute the respective
legal, valid and binding obligations of PDC and the Sellers, enforceable against
PDC and 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 PDC and the Sellers of the Transaction Documents executed by it
will not (a) violate any provision of any law, statute, rule or regulation or
any order, writ, judgment, injunction, decree, determination or award of any
court, governmental agency or arbitrator presently in effect having
applicability to PDC or either Seller, (b) violate or contravene any provisions
of the Articles (or Certificate) of Incorporation or by-laws of PDC or 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 PDC or 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 PDC or either
Seller or any Subsidiary. Neither PDC or nor either 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.

                                      -30-



         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 PDC or 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, the Transaction Documents executed by it.

         Section 8.5  Financial Statements and Condition. PDC's audited
consolidated financial statements as at April 28, 2001 and its unaudited
consolidated financial statements as at January 26, 2002, 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 28, 2001, 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 PDC or either Seller, threatened
against or affecting either PDC or 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 PDC or
either Seller or such Subsidiary, could constitute an Adverse Event.

         Section 8.7  Compliance. PDC and its Subsidiaries, including PDSI and
Webster, 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 PDC or 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 PDC or either Seller or a Subsidiary or which
would require a material expenditure by PDC or either Seller or such Subsidiary
to cure. Neither PDC nor either 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 8.10 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, 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

                                       -31-



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. None of PDC or either 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 PDC or either
Seller or any Subsidiaries is subject to a Lien, except for Permitted Liens.

         Section 8.12 Taxes. Each of PDC, 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 PDC and the Sellers in respect of
taxes and other governmental charges are adequate.

         Section 8.13 Investment Company Act. None of PDC, either Seller or 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. None of PDC, either
Seller or 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 G 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.

         Section 8.16 Partnerships and Joint Ventures. None of PDC, nor either
Seller or any Subsidiary is currently a partner (limited or general) or joint
venturer in any partnership or joint venture, except for Webster Management, LP,
100% of the equity in which is owned by Webster and PDSI.

         Section 8.17 Enforceability of Agreements and Assignments. This
Agreement has been duly executed and delivered by PDC and each Seller and is a
valid and binding agreement of each PDC and 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

                                       -32-



Related Seller enforceable against the Related Seller in accordance with its
terms. Each Seller has full right, power and authority to sell the Buyers'
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 Buyers' 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
Documents 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 Documents 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 financing statements evidencing
Permitted Account Sales. There is only one original executed copy of each
Contract, and on the relevant Purchase Date such original executed copy of each
Contract purchased by the Buyers will be legended in accordance with Section
2.2(ii) and be delivered to the Servicer to be held for the benefit of the
Buyers in accordance with Section 3 hereof.

         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 any 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 such Buyers' Contract and the Related Security. With respect to each
Buyers' 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

                                       -33-



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 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. PDC and 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,

shipment thereof, have been obtained.

                                       -34-



         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.

         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 PDC or 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 PDC or 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 PDC or that Seller, and PDC or 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'

                                       -35-



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
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
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. None of PDC or either 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

                                       -36-



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.

          (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.

          (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 Buyers' Contracts, Related Security, Related
     Security Documents and proceeds or any part thereof shall be sufficient as
     a financing statement where permitted by law.

          (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.

                                      -37-



          (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 Third
     Amended and Restated Contract Purchase Agreement dated as of June 19, 2002
     (as amended) between Patterson Dental Company, Patterson Dental Supply,
     Inc., Webster Veterinary Supply, Inc., U.S. Bank National Association,
     individually and as agent, and the Buyers named therein from time to time."

     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 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.

                                    ARTICLE X
                                GENERAL COVENANTS

     Section 10.1 Corporate Existence. Subject to Section 10.9 in the instance
of a Subsidiary, PDC, 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. PDC, 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

     Section 10.3 Payment of Taxes and Claims. PDC, 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 PDC and 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

                                       -38-



materially interfered with and adequate reserves with respect thereto have been
set aside on PDC, the Seller's or such Subsidiary's books in accordance with
GAAP.

     Section 10.4  Maintenance of Properties. PDC, 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

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. None of PDC, either Seller or 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. None of PDC, either Seller or any Subsidiary
will sell, transfer, lease or otherwise convey all or any substantial part of
its assets except for (a) sales and leases of inventory in the ordinary course
of business, (b) Permitted Account Sales and (c) sales by PDC or a Subsidiary of
PDC to PDC or a Subsidiary of PDC.

     Section 10.11 Plans. None of PDC, either Seller or 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 PDC, either Seller or any
Subsidiary or permit the underfunded amount of Plan benefits guaranteed under
Title IV of ERISA to exceed $500,000.

                                      -39-

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

     Section 10.13 Liens. None of PDC, either Seller or 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. None of PDC, either Seller or 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 PDC
or 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 Accounting Changes. PDC or the Sellers will not, and will not
permit any Subsidiary to, make any change in accounting treatment or reporting

any determination made or required to be made hereunder, or change their fiscal
year or the fiscal year of any Subsidiary.

     Section 10.16 Changes in Name or Location. None of PDC nor either Seller
will at any time change its name, identity, address of its chief executive
office or corporate structure (including without limitation changing its
jurisdiction of organization) in any manner which would, could or might make any
financing or continuation statement filed hereunder seriously misleading within
the meaning of ss. 9-503 or ss. 9-507 (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 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 10.17 Indemnity. PDC and each Seller 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):

          (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;

          (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;

                                      -40-



          (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;

          (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;

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

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

provided, however, that PDC and 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.

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 10.19 Guaranties. When so requested by the Agent from time to time,
PDC will execute and deliver to the Agent reaffirmations of the PDC Guaranty in
such form as the Agent may require.

                                      -41-

     to terminate any Plan if in order to effectuate such termination, PDC, the

     of $2,000,000, or the institution by the PBGC of steps to terminate any

     Seller or a Subsidiary shall fail to pay any such indebtedness in such
     amount when due or, in the case of such indebtedness payable on demand,
     when demanded, or any event shall occur or condition shall exist and shall
     continue for more than the period of grace, if any, applicable thereto and
     shall have the effect of causing, or permitting the holder of any such
     indebtedness or any trustee or other Person acting on behalf of such holder
     to cause, such indebtedness in such amount to become due prior to its
     stated maturity or to realize upon any collateral given as security
     therefor;

          (j)  Any Person, or group of Persons acting in concert, that owned
     less than 5% of the shares of any voting class of stock of PDC shall have
     acquired more than 50% of the shares of such voting stock;

          (k)  This Agreement or the PDC Guaranty shall, at any time after the
     execution and delivery hereof, cease to be in full force and effect or
     shall be declared to be null and void, or the validity or enforceability
     thereof shall be contested by PDC or any Seller, or PDC or any Seller shall
     deny that it has any or further liability or obligation under this
     Agreement or PDC's Guaranty;

          (l)  Any execution or attachment shall be issued whereby any
     substantial part of the property of PDC, a Seller or any Subsidiary shall
     be taken or attempted to be taken and the same shall not have been vacated
     or stayed within 30 days after the issuance thereof; or

          (m)  PDSI or Webster shall cease to be a wholly-owned Subsidiary of
     PDC; or

          (n)  That certain Escrow Agreement among PDC, PDSI, the Agent and U.S.
     Bank National Association shall be terminated, amended or otherwise

     and not be replaced with a substitute escrow agent satisfactory to the
     Majority Buyers; or

          (o)  The Intercreditor Agreement shall, at any time after the
     execution and delivery thereof, be breached by any Seller or Bank One, NA,
     cease to be in full force

                                      -43-



     and effect or shall be declared to be null and void, or the validity or
     enforceability thereof shall be contested by any Seller or Bank One, NA, or
     any Seller or Bank One, NA, shall deny that it has any or further liability
     or obligation under the Intercreditor Agreement.

     Section 11.2 Remedies.

          (a)     If (i) any Termination Event described in Sections 11.1(e),
     (f) or (g) shall occur with respect to PDC, a Seller, the Contract Purchase
     Commitment shall automatically terminate and each Seller shall without
     demand pay into the Holding Account an amount equal to its Individual
     Repurchase Commitment Amount as of such date; or (ii) any other Termination
     Event shall occur and be continuing, then the Agent may, and at the request
     of the Majority Buyers shall, (A) declare the Contract Purchase Commitment
     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.

          (b)     Upon the occurrence of any Termination Event:

                  (i)  the Agent may exercise and enforce any and all rights and
          remedies available upon default to a secured party under the Uniform
          Commercial Code;

                  (ii) the Agent may deliver notice of the Buyers' purchase of
          the 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, 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

                                      -44-



          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 PDC and each Seller to, and PDC
          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 PDC and a Seller
          (including under PDC Guaranty), 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.

                                   ARTICLE XII
                             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

                                      -45-



     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 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;

                                      -46-



          (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 Prime 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 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 Prime 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

                                      -47-



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.

                                  ARTICLE XIII
                                  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 PDC or a
Seller not required hereunder or under an Assignment shall in any event entitle
PDC or either 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 PDC or 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:

          (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

          (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

          (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

          (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

                                      -48-



          (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

          (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 the Transaction Documents. PDC and
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 the Transaction Documents, the Buyers'
Contracts and the Related Security Documents. PDC and the Sellers jointly 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 PDC and 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.

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

          (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

                                      -49-



          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) PDC,
          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 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. PDC and 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.

               (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, pursuant to written agreements executed by
          such assigning Buyer, such Assignee(s) and the Agent in substantially
          the form of Exhibit H, 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, PDC, 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
          PDC and 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 Contract Purchase
          Commitment Amount assumed by such

                                      -50-



     Assignee and (z) the address for notices to such Assignee shall be as

     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

                                       -53-



     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 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,


                                       -54-



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 H.

     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.

     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

                                      -55-



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 PDC or 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 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 PDC or 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 PDC or 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 PDC or the Sellers to such Buyer arising under or pursuant
to this Agreement and to any participations held by such

                                       -56-



Buyer in indebtedness of PDC or the Sellers arising under or pursuant to this,
and only then to any other indebtedness of PDC or 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 PDC or the Sellers by it as Agent, excluding, however, notices,
reports and communications which by the terms hereof are to be furnished by PDC
or 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, the
Sellers and PDC a written notification of 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.

                                      -57-



         IN WITNESS WHEREOF, the parties hereto have caused this Agreement to be
executed as of the date first above.
