                             PRELIMINARY STATEMENTS

                  Each Originator now owns, and from time to time hereafter will
         own, Originated Receivables. Each Originator wishes to sell and assign
         to Buyer, and Buyer wishes to purchase from such Originator, all of
         such Originator's right, title and interest in and to certain of such
         Originated Receivables, together with the Related Security and
         Collections with respect thereto.

                  Each Originator and Buyer intend the transactions contemplated
         hereby to be true sales of the Receivables from such Originator to
         Buyer, providing Buyer with the full benefits of ownership of the
         Receivables, and neither of the Originators nor Buyer intends these
         transactions to be, or for any purpose to be characterized as, loans
         from Buyer to any Originator.

                  Following each purchase of Receivables from the Originators,
         Buyer will sell undivided interests therein and in the associated
         Related Security and Collections pursuant to that certain Receivables
         Purchase Agreement dated as of May 10, 2002 (as the same may from time
         to time hereafter be amended, supplemented, restated or otherwise
         modified, the "Purchase Agreement") among Buyer, the Servicer (as
         defined therein), the Conduit (as defined therein), the financial
         institutions from time to time party thereto as "Financial
         Institutions" and Bank One, NA (Main Office Chicago), as agent for the
         Conduit and Financial Institutions or any successor agent appointed
         pursuant to the terms of the Purchase Agreement (in such capacity, the
         "Agent").

                                    AGREEMENT

                  NOW, THEREFORE, in consideration of the foregoing premises and
the mutual agreements herein contained and other good and valuable
consideration, the receipt and adequacy of which are hereby acknowledged, the
parties hereto agree as follows:

                                                      RECEIVABLES SALE AGREEMENT

                                    ARTICLE I
                        AMOUNTS AND TERMS OF THE PURCHASE

                  Section 1.1 Purchases of Receivables.

                          (a) Agreement to Sell and Purchase. (i) Upon the terms
and subject to the conditions set forth herein, each Originator may, at its
option from time to time, sell, assign, transfer and convey to Buyer, without
recourse (except to the extent expressly provided herein), and Buyer may, at its
option, purchase from such Originator, all of Originator's right, title and
interest in, to and under certain Originated Receivables owned by such
Originator, together, in each case, with all Related Security and Collections
with respect thereto. In connection with the payment of the Purchase Price for
any Receivables, Buyer may request that Originator selling such Receivables
deliver, and such Originator shall deliver, such approvals, opinions,
information, reports or documents as Buyer may reasonably request.

                              (ii) Not less than two Business Days prior to each
date on which any Originator proposes to sell Originated Receivables to Buyer,
such Originator shall deliver to Buyer (i) a notice that such Originator
proposes to sell to Buyer, on the specified Purchase Date, Originated
Receivables, and (ii) an executed Sale Assignment, to which shall be attached a
schedule of the Originated Receivables to be sold on such Purchase Date,
identified at least by contract number, Obligor and principal amount outstanding
as of such Purchase Date or any other date identified in such Sale Assignment.
Effective upon Buyer's acceptance of such Sale Assignment, such Originator does
hereby sell to Buyer without recourse (except to the extent expressly provided
herein), and Buyer does hereby purchase or acquire, from such Originator, all of
Originator's right, title and interest in and to the Originated Receivables
identified in such Sale Assignment. The schedule attached to the first Sale
Assignment delivered pursuant to this Section 1.1(a)(ii) shall be deemed to be
Schedule B to this Agreement (and this Agreement shall be deemed, automatically
and without further action by any Person, supplemented and modified thereby) and
each schedule attached to any Sale Assignment thereafter delivered pursuant to
this Section 1.1(a)(ii) shall be deemed to amend and supplement Schedule B
hereto. Buyer shall be obligated to pay the Purchase Price for the Receivables
purchased hereunder in accordance with Section 1.2.

                          (b) It is the intention of the parties hereto that
each Purchase of Receivables made hereunder shall constitute a sale, which sale
is absolute and irrevocable and provides Buyer with the full benefits of
ownership of the Receivables. Except for the Purchase Price Credits owed
pursuant to Section 1.3, each sale of Receivables hereunder is made without
recourse to any Originator; provided, however, that (i) each Originator shall be
liable to Buyer for all representations, warranties, covenants and indemnities
made by such Originator pursuant to the terms of the Transaction Documents to
which such Origina-

tor is a party, and (ii) such sale does not constitute and is not intended to
result in an assumption by Buyer or any assignee thereof of any obligation of
any Originator or any other Person arising in connection with the Receivables,
the related Contracts and/or other Related Security or any other obligations of
any Originator. In view of the intention of the parties hereto that the
Purchases of Receivables made hereunder shall constitute sales of such
Receivables rather than loans secured thereby, each Originator agrees that it
will, on or prior to the date hereof and in accordance with Section 4.1(e)(ii),
mark its master data processing records relating to the Receivables with a
legend acceptable to Buyer and to the Agent (as Buyer's assignee), evidencing
that Buyer has purchased such Receivables as provided in this Agreement and to
note in its financial statements that its Receivables have been sold to Buyer.
Upon the request of Buyer or the Agent (as Buyer's assignee), each Originator
will execute and file such financing or continuation statements, or amendments
thereto or assignments thereof, and such other instruments or notices, as may be
necessary or appropriate to perfect and maintain the perfection of Buyer's
ownership interest in the Receivables and the Related Security and Collections
with respect thereto, or as Buyer or the Agent (as Buyer's assignee) may
reasonably request.

                  Section 1.2 Payment for the Purchase.

                          (a) The Purchase Price for any Purchase of Receivables
hereunder shall be payable in full by Buyer to the Originator of such
Receivables in accordance with Section 1.2(b), and shall be paid to such
Originator in the following manner:

                                       (i)  by delivery of immediately available
         funds, to the extent of funds made available to Buyer in connection
         with its subsequent sale of an interest in such Receivables to the
         Purchasers under the Purchase Agreement or other cash on hand; and

                                       (ii) the balance, by delivery of the
         proceeds of a subordinated revolving loan from such Originator to Buyer
         (a "Subordinated Loan") in an amount not to exceed the least of (A) the
         remaining unpaid portion of such Purchase Price, (B) the maximum
         Subordinated Loan that could be borrowed without rendering Buyer's Net
         Worth less than the Required Capital Amount and (C) the maximum
         Subordinated Loan that could be borrowed without rendering the Net
         Value less than the aggregate outstanding principal balance of the
         Subordinated Loans (including the Subordinated Loan proposed to be made
         on such date). Each Originator is hereby authorized by Buyer to endorse
         on the schedule attached to its Subordinated Note an appropriate
         notation evidencing the date and amount of each advance thereunder, as
         well as the date of each payment with respect thereto, provided that
         the failure to make such notation shall not affect any obligation of
         Buyer thereunder.

<PAGE>

                                                      RECEIVABLES SALE AGREEMENT

Subject to the limitations set forth in Section 1.2(a)(ii), each Originator
irrevocably agrees to advance each Subordinated Loan requested by Buyer on or
prior to the Termination Date. The Subordinated Loans shall be evidenced by, and
shall be payable in accordance with the terms and provisions of the Subordinated
Notes and shall be payable solely from funds which Buyer is not required under
the Purchase Agreement to set aside for the benefit of, or otherwise pay over
to, the Purchasers.

                        (b)  The Purchase Price for each Receivable purchased
hereunder shall be due and payable in full by Buyer to the Originator of such
Receivable on the Purchase Date for such Receivable, provided that settlement of
the Purchase Price between Buyer and each Originator shall be effected on the
next occurring Settlement Date (or, if the Purchase Date is a Settlement Date,
on such Settlement Date). In addition, increases or decreases in the amount
owing under the Subordinated Notes made pursuant to Section 1.2(a) shall be
deemed to have occurred and shall be effective as of the next Settlement Date to
occur after such increase or decrease.

                Section 1.3  Purchase Price Credit Adjustments. If on any day:

                        (a)  the Outstanding Balance of a Receivable is:

                                   (i)  reduced as a result of any defective or
         rejected or returned goods or services, any discount or any adjustment
         or otherwise by the Originator of such Receivable (other than cash
         Collections on account of the Receivables),

                                   (ii) reduced or canceled as a result of a
         setoff in respect of any claim by any Person (whether such claim arises
         out of the same or a related transaction or an unrelated transaction),
         or

                        (b)  any of the representations and warranties set forth
in Article II are not true when made or deemed made with respect to any
Receivable, or

                        (c)  the Related Equipment for any Receivable is
Repossessed and sold for less than the fair market value of such Related
Equipment,

then, in such event, Buyer shall be entitled to a credit (each, a "Purchase
Price Credit") against the Purchase Price otherwise payable hereunder to the
Originator of such Receivable equal to (i) in the case of clause (a) above, the
amount of such reduction or cancellation, (ii) in the case of clause (b) above,
the Outstanding Balance of such Receivable and in the case of clause (c) above,
the difference between the fair market value of the Repossessed Related
Equipment and the gross proceeds received upon the sale of such Repossessed
Related

                                        4

                                                      RECEIVABLES SALE AGREEMENT

Equipment. If such Purchase Price Credit exceeds the Purchase Price on any day,
then such Originator shall pay the remaining amount of such Purchase Price
Credit in cash immediately, provided that if the Termination Date has not
occurred, such Originator shall be allowed to deduct the remaining amount of
such Purchase Price Credit from any indebtedness owed to it under such
Originator's Subordinated Note.

                  Section 1.4 Payments and Computations, Etc. All amounts to be
paid or deposited by Buyer hereunder shall be paid or deposited in accordance
with the terms hereof on the day when due in immediately available funds to the
account of the applicable Originator as designated from time to time by such
Originator or as otherwise directed by such Originator. In the event that any
payment owed by any Person hereunder becomes due on a day that is not a Business
Day, then such payment shall be made on the next succeeding Business Day. If any
Person fails to pay any amount hereunder when due, such Person agrees to pay, on
demand, the Default Fee in respect thereof until paid in full; provided,
however, that such Default Fee shall not at any time exceed the maximum rate
permitted by applicable law. All computations of interest payable hereunder
shall be made on the basis of a year of 360 days for the actual number of days
(including the first but excluding the last day) elapsed.

                  Section 1.5 Transfer of Records.

                          (a) In connection with each Purchase of Receivables
hereunder, each Originator hereby sells, transfers, assigns and otherwise
conveys to Buyer all of such Originator's right and title to and interest in the
Records relating to all Receivables sold hereunder, without the need for any
further documentation in connection with the Purchase. In connection with such
transfer, each Originator hereby grants to each of Buyer, the Agent and the
Servicer an irrevocable, non-exclusive license to use, without royalty or
payment of any kind, all software used by such Originator to account for its
Receivables, to the extent necessary to administer such Receivables, whether
such software is owned by such Originator or is owned by others and used by such
Originator under license agreements with respect thereto, provided that should
the consent of any licensor of such software be required for the grant of the
license described herein, to be effective, such Originator hereby agrees that
upon the request of Buyer (or Buyer's assignee), such Originator will use its
reasonable efforts to obtain the consent of such third-party licensor. The
license granted hereby shall be irrevocable until the indefeasible payment in
full of the Aggregate Unpaids, and shall terminate on the date this Agreement
terminates in accordance with its terms.

                          (b) Each Originator (i) shall take such action
requested by Buyer and/or the Agent (as Buyer's assignee), from time to time
hereafter, that may be necessary or appropriate to ensure that Buyer and its
assigns under the Purchase Agreement have an enforceable ownership interest in
the Records relating to the Receivables purchased from such Originator
hereunder, and (ii) shall use its reasonable efforts to ensure that Buyer, the

                                        5

                                                      RECEIVABLES SALE AGREEMENT

Agent and the Servicer each has an enforceable right (whether by license or
sublicense or otherwise) to use all of the computer software used to account for
the Receivables and/or to recreate such Records.

                  Section 1.6 Characterization. If, notwithstanding the
intention of the parties expressed in Section 1.1(b), any sale by any Originator
to Buyer of Receivables hereunder shall be characterized as a secured loan and
not a sale or such sale shall for any reason be ineffective or unenforceable,
then this Agreement shall be deemed to constitute a security agreement under the
UCC and other applicable law. For this purpose and without being in derogation
of the parties' intention that the sale of Receivables hereunder shall
constitute a true sale thereof, each Originator hereby grants to Buyer a duly
perfected security interest in all of such Originator's right, title and
interest in, to and under all Receivables now existing and hereafter arising,
all Collections and Related Security with respect thereto, each Lock-Box, P.O.
Box and Collection Account, all other rights and payments relating to such
Originator's Receivables and all proceeds of the foregoing to secure the prompt
and complete payment of a loan deemed to have been made in an amount equal to
the aggregate Purchase Price of the Receivables together with all other
obligations of such Originator hereunder, which security interest shall be prior
to all other Adverse Claims thereto. Buyer and its assigns shall have, in
addition to the rights and remedies which they may have under this Agreement,
all other rights and remedies provided to a secured creditor under the UCC and
other applicable law, which rights and remedies shall be cumulative.

                                   ARTICLE II
                         REPRESENTATIONS AND WARRANTIES

                  Section 2.1 Representations and Warranties of Originator.
Each Originator hereby represents and warrants to Buyer on the date hereof and
on the date of each Purchase that:

                          (a) Corporate Existence and Power. Such Originator is
a corporation, duly organized and validly existing and in good standing under
the laws of its state of incorporation. Each such Originator is duly qualified
to do business and is in good standing as a foreign corporation, and has and
holds all corporate power and all governmental licenses, authorizations,
consents and approvals required to carry on its business in each jurisdiction in
which its business is conducted, except where the failure to be so qualified or
to have and hold such governmental licenses, authorizations, consents and
approvals could not reasonably be expected to have a Material Adverse Effect.

                          (b) Power and Authority; Due Authorization, Execution
and Delivery. The execution and delivery by such Originator of this Agreement
and each other Transaction Document to which it is a party, and the performance
of its obligations

hereunder and thereunder and such Originator's use of the proceeds of each
Purchase from such Originator made hereunder, are within its corporate powers
and authority, and have been duly authorized by all necessary corporate action
on its part. This Agreement and each other Transaction Document to which such
Originator is a party has been duly executed and delivered by such Originator.

                  (c) No Conflict. The execution and delivery by such Originator
of this Agreement and each other Transaction Document to which it is a party,
and the performance of its obligations hereunder and thereunder do not
contravene or violate (i) its certificate or articles of incorporation or
by-laws (or equivalent organizational documents) or any shareholder agreements,
voting trusts or similar arrangements applicable to any of its authorized
shares, (ii) any law, rule or regulation applicable to it, (iii) any
restrictions under any agreement, contract or instrument to which it is a party
or by which it or any of its property is bound, or (iv) any order, writ,
judgment, award, injunction or decree binding on or affecting it or its
property, and do not result in the creation or imposition of any Adverse Claim
on assets of such Originator or its Subsidiaries (except as created hereunder).
No transaction contemplated hereby requires compliance with any bulk sales act
or similar law.

                  (d) Governmental Authorization. Other than the filing of the
financing statements required hereunder, no authorization or approval or other
action by, and no notice to or filing with, any governmental authority or
regulatory body is required for the due execution and delivery by such
Originator of this Agreement and each other Transaction Document to which it is
a party and the performance of its obligations hereunder and thereunder.

                  (e) Actions, Suits. There are no actions, suits or proceedings
pending, or to the best of such Originator's knowledge, threatened, against or
affecting such Originator, or any of its properties, in or before any court,
arbitrator or other body, that could reasonably be expected to have a Material
Adverse Effect. Such Originator is not in default with respect to any order of
any court, arbitrator or governmental body.

                  (f) Binding Effect. This Agreement and each other Transaction
Document to which such Originator is a party constitute the legal, valid and
binding obligations of such Originator enforceable against such Originator in
accordance with their respective terms, except as such enforcement may be
limited by applicable bankruptcy, insolvency, reorganization or other similar
laws relating to or limiting creditors' rights generally and by general
principles of equity (regardless of whether enforcement is sought in a
proceeding in equity or at law).

                  (g) Accuracy of Information. All information heretofore
furnished by such Originator or any of its Affiliates to Buyer (or its assigns)
for purposes of or in connection with this Agreement, any of the other
Transaction Documents or any

transaction contemplated hereby or thereby is, and all such information
hereafter furnished by such Originator or any of its Affiliates to Buyer (or its
assigns) will be, true and accurate in every material respect on the date such
information is stated or certified and does not and will not contain any
material misstatement of fact or omit to state a material fact or any fact
necessary to make the statements contained therein not materially misleading.

                  (h) Use of Proceeds. No proceeds of any Purchase hereunder
will be used (i) for a purpose that violates, or would be inconsistent with, any
law, rule or regulation applicable to such Originator or (ii) to acquire any
security in any transaction which is subject to Section 12, 13 or 14 of the
Securities Exchange Act of 1934, as amended.

                  (i) Good Title. Immediately prior to each Purchase hereunder,
such Originator (i) is the legal and beneficial owner of the Receivables to be
sold by such Originator hereunder, and (ii) is the legal and beneficial owner of
the Related Security with respect thereto or possesses a valid and perfected
security interest therein, in each case, free and clear of any Adverse Claim,
except as created by the Transaction Documents. There have been duly filed all
financing statements or other similar instruments or documents necessary under
the UCC (or any comparable law) of all appropriate jurisdictions to perfect such
Originator's ownership interest in each Receivable, its Collections and the
Related Security.

                  (j) Perfection. This Agreement, together with the filing of
the financing statements contemplated hereby and the executed Sale Assignments,
is effective to transfer to Buyer (and Buyer shall acquire from such Originator)
(i) legal and equitable title to, with the right to sell and encumber, each
Receivable existing or hereafter arising, together with the Collections with
respect thereto, and (ii) all of such Originator's right, title and interest in
the Related Security associated with each Receivable, in each case, free and
clear of any Adverse Claim, except as created by the Transactions Documents.
There have been duly filed all financing statements or other similar instruments
or documents necessary under the UCC (or any comparable law) of all appropriate
jurisdictions to perfect Buyer's ownership interest in the Receivables, the
Related Security and the Collections.

                  (k) Jurisdiction of Organization; Places of Business; etc.

organization, Federal Employer's Identification Number and State Organizational
Identification Number. Such Originator's principal places of business and chief
executive office and the offices where it keeps all of its Records are located
at the address(es) listed on Exhibit II or such other locations of which Buyer
has been notified in accordance with Section 4.2(a) in jurisdictions where all
action required by Section 4.1(g) or Section 7.3(a) has been taken and

date hereof, (i) changed the location of its principal place of business or
chief executive office or,

Minnesota) or (iv) changed its jurisdiction of organization. Such Originator is
a "registered organization" (within the meaning of Section 9-102 of the UCC as

                  (l) Collections. The conditions and requirements set forth in
Section 4.1(i) have at all times been satisfied and duly performed. The names
and addresses of all Collection Banks, together with the account numbers of the
Collection Accounts at each Collection Bank and the post office box number of
each Lock-Box or P.O. Box, are listed on Exhibit III. Such Originator has not
granted any Person, other than Buyer (and its assigns) dominion and control or
"control" (within the meaning of Section 9-104 of the UCC of all applicable
jurisdictions) of any Lock-Box, P.O. Box or Collection Account, or the right to
take dominion and control or "control" (within the meaning of Section 9-104 of
the UCC of all applicable jurisdictions) of any such Lock-Box, P.O. Box or
Collection Account at a future time or upon the occurrence of a future event.
Such Originator has taken all steps necessary to ensure that Buyer (or its
assigns) has "control" (within the meaning of Section 9-104 of the UCC of all
applicable jurisdictions) over all Collection Accounts. Such Originator has the
ability to identify, within one Business Day of deposit, all amounts that are
deposited to any First-Tier Account as constituting Collections or
non-Collections.

                  (m) Material Adverse Effect. Since January 26, 2002, no event
has occurred that would have a Material Adverse Effect.

                  (n) Names. In the past five (5) years, such Originator has not
used any corporate or other names, trade names or assumed names other than as
listed on Exhibit II.

                  (o) Ownership of Buyer. PDCo owns 100% of the issued and
outstanding membership units of Buyer, free and clear of any Adverse Claim. Such
membership units are validly issued, fully paid and nonassessable, and there are
no options, warrants or other rights to acquire securities of Buyer.

                  (p) Not a Holding Company or an Investment Company. Such
Originator is not a "holding company" or a "subsidiary holding company" of a
"holding company" within the meaning of the Public Utility Holding Company Act
of 1935, as amended, or any successor statute. Such Originator is not and, after
giving effect to the transactions contemplated hereby, will not be required to
be registered as, an "investment company" within the meaning of the Investment
Company Act of 1940, as amended, or any successor statute.

                  (q) Compliance with Law. Such Originator has complied in all
respects with all applicable laws, rules, regulations, orders, writs, judgments,
injunctions, decrees or awards to which it may be subject, except where the
failure to so comply could not reasonably be expected to have a Material Adverse
Effect. Each Receivable, together with any Contract related thereto, does not
contravene any laws, rules or regulations applicable thereto (including, without
limitation, laws, rules and regulations relating to truth in lending, fair
credit billing, fair credit reporting, equal credit opportunity, fair debt
collection practices and privacy), and no part of such Contract is in violation
of any such law, rule or regulation.

                  (r) Compliance with Credit and Collection Policies. Such
Originator has complied in all material respects with such Originator's Credit
and Collection Policy with regard to each Receivable and any related Contract,
and has not made any material change to such Credit and Collection Policy,
except such material change as to which Buyer (or its assigns) has been notified
in accordance with Section 4.1(a)(vii).

                  (s) Payments to Originator. With respect to each Receivable
transferred to Buyer by such Originator hereunder, the Purchase Price received
by such Originator constitutes reasonably equivalent value in consideration
therefor and such transfer was not made for or on account of an antecedent debt.
No transfer by such Originator of any Receivable hereunder is or may be voidable
under any section of the Federal Bankruptcy Code.

                  (t) Enforceability of Contracts. Each Contract with respect to
each Receivable sold by such Originator hereunder is effective to create, and
has created, a legal, valid and binding obligation of the related Obligor to pay
the Outstanding Balance of the Receivable created thereunder and any accrued
interest thereon, enforceable against the Obligor in accordance with its terms,
except as such enforcement may be limited by applicable bankruptcy, insolvency,
reorganization or other similar laws relating to or limiting creditors' rights
generally and by general principles of equity (regardless of whether enforcement
is sought in a proceeding in equity or at law).

                  (u) Eligible Receivables. Each Receivable sold by such
Originator hereunder and included at any time in the Net Receivables Balance as
an Eligible Receivable was, on its Purchase Date, an Eligible Receivable.

                  (v) Accounting. The manner in which such Originator accounts
for the transactions contemplated by this Agreement does not jeopardize the
characterization of the transactions contemplated herein as being true sales.

                  (w) No Adverse Selection. To the extent that such Originator
has retained Originated Receivables that would be Eligible Receivables but which
have not been

transferred to Buyer hereunder, such Originator has not selected those
Originated receivables to be transferred hereunder in any manner that materially
adversely affects Buyer.

                                   ARTICLE III
                             CONDITIONS OF PURCHASE

               Section 3.1 Conditions Precedent to Purchase. The initial
Purchase under this Agreement is subject to the conditions precedent that (a)
Buyer shall have received on or before the date of such Purchase those documents
listed on Schedule A and (b) all of the conditions precedent to the initial
Incremental Purchase under the Purchase Agreement shall have been satisfied or
waived in accordance with the terms thereof.

               Section 3.2 Conditions Precedent to Subsequent Payments. Buyer's
obligation to pay for Receivables on any Purchase Date shall be subject to the
further conditions precedent that (a) the Facility Termination Date shall not
have occurred; (b) Buyer (or its assigns) shall have received the notice
required pursuant to Section 1.1(a)(ii), an executed Sale Assignment and such
other approvals, opinions or documents as it may reasonably request and (c) on
the Purchase Date for such Receivables, the following statements shall be true
(and acceptance of the proceeds by any Originator of any payment for such
Receivable shall be deemed a representation and warranty by such Originator that
such statements are then true):

                         (i) the representations and warranties of such
     Originator set forth in Article II are true and correct on and as of such
     Purchase Date (and after giving effect to the Purchase consummated thereon)
     as though made on and as of such date; and

                         (ii) no event has occurred and is continuing that will
     constitute a Termination Event or a Potential Termination Event.

Notwithstanding the foregoing conditions precedent, upon payment of the Purchase
Price for any Receivable (whether by payment of cash, through an increase in the
amounts outstanding under the Subordinated Notes and/or by offset of amounts
owed to Buyer), title to such Receivable and the Related Security and
Collections with respect thereto shall vest in Buyer, whether or not the
conditions precedent to Buyer's obligation to pay for such Receivable were in
fact satisfied. The failure of any Originator to satisfy any of the foregoing
conditions precedent, however, shall give rise to a right of Buyer to rescind
the related purchase and direct such Originator to pay to Buyer an amount equal
to the Purchase Price that shall have been paid with respect to any Receivables
related thereto.

of such Originator and the Collections and (B) all of such Originator's right,

or documents necessary under the UCC (or any comparable law) of all appropriate
jurisdictions to perfect Buyer's interest in such Receivables, Related Security

after the date of execution and delivery of this Agreement, such Originator will
take all reasonable steps including, without limitation, all steps that Buyer or
any assignee of Buyer may from time to time reasonably request to maintain
Buyer's identity as a separate legal entity and to make it manifest to third
parties that Buyer is an entity with assets and liabilities distinct from those
of such Originator and any Affiliates thereof and not just a division of such
Originator or any such Affiliate. Without limiting the generality of the
foregoing and in addition to the other covenants set forth herein, such
Originator (i) will not hold itself out to third parties as liable for the debts
of Buyer nor purport to own the Receivables and other assets acquired by Buyer,
(ii) will take all other actions necessary on its part to ensure that Buyer is
at all times in compliance with the covenants set forth in Section 7.1(i) of the
Purchase Agreement and (iii) will cause all tax liabilities arising in
connection with the transactions contemplated herein or otherwise to be
allocated between such Originator and Buyer on an arm's-length basis and in a
manner consistent with the procedures set forth in U.S. Treasury Regulations
"1.1502-33(d) and 1.1552-1.

Account, (2) all Collections deposited to any First-Tier Account to be
electronically swept or otherwise transferred to the Second-Tier Account within
1 Business Day after deposit to such First-Tier Account, and (3) each Lock-Box,
P.O. Box and Collection Account to be subject at all times to a Collection
Account Agreement that is in full force and effect. In the event any payments
relating to Receivables are remitted directly to such Originator or any
Affiliate of such Originator, such Originator will remit such payments (or will
cause all such payments to be remitted) directly to a Collection Bank for
deposit into a Collection Account within one (1) Business Day following receipt
thereof and, at all times prior to such remittance, such Originator will itself
hold such payments or, if applicable, will cause such payments to be held, in
trust for the exclusive benefit of Buyer

and its assigns. Such Originator will transfer exclusive ownership, dominion and
control (including "control" within the meaning of Section 9-104 of the UCC of
all applicable jurisdictions) of each Lock-Box, P.O. Box and Collection Account
to Buyer and will not grant the right to take dominion and control or grant
"control" (within the meaning of Section 9-104 of the UCC of all applicable
jurisdictions) of any Lock-Box, P.O. Box or Collection Account at a future time
or upon the occurrence of a future event to any Person, except to Buyer (or its
assigns) as contemplated by this Agreement and the Purchase Agreement.

                    (j) Taxes. Such Originator will file all tax returns and
reports required by law to be filed by it and promptly pay all taxes and
governmental charges at any time owing. Such Originator will pay when due any
taxes payable in connection with the Receivables of such Originator, exclusive
of taxes on or measured by income or gross receipts of Buyer and its assigns.

                    (k) Insurance. Such Originator will maintain in effect, or
cause to be maintained in effect, at such Originator's own expense, such
casualty and liability insurance as such Originator deems appropriate in its
good faith business judgment. Buyer and the Agent, for the benefit of the
Purchasers, shall be named as additional insureds with respect to all such
liability insurance maintained by such Originator. Such Originator will pay, or
cause to be paid, the premiums therefor and deliver to Buyer and the Agent
evidence satisfactory to Buyer and the Agent of such insurance coverage. Copies
of each policy shall be furnished to Buyer, the Agent and any Purchaser in
certificated form upon Buyer's, the Agent's or such Purchaser's request.

          Section 4.2   Negative Covenants of the Originators. Until the date on
which this Agreement terminates in accordance with its terms, each Originator
hereby covenants that:

                    (a) Name Change, Jurisdiction of Organization, Offices and
Books of Account. Such Originator will not change its name, jurisdiction of
organization, identity, corporate or other organizational structure (within the
meaning of Sections 9-503 and/or 9-507 of the UCC of all applicable
jurisdictions) or relocate its chief executive office, principal place of
business or any office where Records are kept unless it shall have: (i) given
Buyer (or its assigns) at least forty-five(45) days' prior written notice
thereof and (ii) delivered to Buyer (or its assigns) all financing statements,
instruments and other documents requested by Buyer (or its assigns) in
connection with such change or relocation acceptable to the Agent.

                    (b) Change in Payment Instructions to Obligors. Such
Originator will not add or terminate any bank as a Collection Bank, or make any
change in the instructions to Obligors regarding payments to be made to any Lock
Box, P.O. Box or

Collection Account Agreement with respect to the new Collection Account or
Lock-Box or P.O. Box; provided, however, that such Originator may make changes
in instructions to Obligors regarding payments if such new instructions require
such Obligor to make payments to another existing Collection Account.

                    (c) Modifications to Contracts and Credit and Collection
Policy. Such Originator will not make any change to its Credit and Collection
Policy that could adversely affect the collectibility of the Receivables of such
Originator, or decrease the credit quality of any newly created Receivables of
such Originator. Except as otherwise permitted in its capacity as sub-Servicer
pursuant to Article VIII of the Purchase Agreement, such Originator will not
extend, amend or otherwise modify the terms of any Receivable or the Contract
related thereto other than in accordance with such Originator's Credit and
Collection Policy.

operation of law or otherwise) or otherwise dispose of, or grant any option with
respect to, or create or suffer to exist any Adverse Claim upon (including,
without limitation, the filing of any financing statement) or with respect to,
any Receivable of such Originator or any Related Security or Collections, or
upon or with respect to the Contract under which any Receivable of such
Originator arises, or any Lock-Box, P.O. Box or Collection Account, or assign
any right to receive income with respect thereto (other than, in each case, the
creation of the interests therein in favor of Buyer provided for herein), and
such Originator will defend the right, title and interest of Buyer in, to and
under any of the foregoing property, against all claims of third parties
claiming through or under such Originator. Such Originator shall not create or
suffer to exist any mortgage, pledge, security interest, encumbrance, lien,
charge or other similar arrangement on any of its inventory the financing or
lease of which gives rise to any Receivable of such Originator.

                    (e) No Adverse Selection. To the extent that such Originator
has retained Originated Receivables that would be Eligible Receivables but which
have not been transferred to Buyer hereunder, such Originator will not select
those Originated Receivables to be transferred hereunder in any manner that
materially adversely affects Buyer.

                    (f) Accounting for Purchase. Such Originator will not, and
will not permit any Affiliate to, account for or treat (whether in financial
statements or otherwise) the transactions contemplated hereby in any manner
other than the sale of the Receivables of such Originator and the Related
Security by such Originator to Buyer or in any other respect account for or

recognized on account of consolidated financial reporting in accordance with

otherwise credit, or cause or permit to be so deposited or credited, to the
Second-Tier Account, cash or cash proceeds other than Collections. Such
Originator will not deposit or otherwise credit, or cause or permit to be so
deposited or credited, any Collections or proceeds thereof to any lock-box

deemed made.

                    (c) Failure of any Originator to pay any Indebtedness when
due in excess of $1,000,000; or the default by such Originator in the
performance of any term, provision or condition contained in any agreement under
which any such Indebtedness was created or is governed, the effect of which is
to cause, or to permit the holder or holders of such Indebtedness to cause, such
Indebtedness to become due prior to its stated maturity; or any such
Indebtedness of such Originator shall be declared to be due and payable or
required to be prepaid (other than by a regularly scheduled payment) prior to
the date of maturity thereof.

                    (d) (i) Any Originator or any of its Subsidiaries shall
generally not pay its debts as such debts become due or shall admit in writing
its inability to pay its debts generally or shall make a general assignment for
the benefit of creditors; or (ii) any proceeding shall be instituted by or
against any Originator or any of its Subsidiaries seeking to adjudicate it
bankrupt or insolvent, or seeking liquidation, winding up, reorganization,
arrangement, adjustment, protection, relief or composition of it or its debts
under any law relating to bankruptcy, insolvency or reorganization or relief of
debtors, or seeking the entry

similar official for it or any substantial part of its property and, solely in
the case of a proceeding instituted against (and not by) such Originator, such
proceeding is not dismissed within 60 days; or (iii) any Originator or any of
its Subsidiaries shall take any corporate action to authorize any of the actions
set forth in the foregoing clauses (i) or (ii) of this subsection (d).

                    (e) A Change of Control shall occur.

                    (f) One or more final judgments for the payment of money in
an amount in excess of $1,000,000, individually or in the aggregate, shall be
entered against any Originator on claims not covered by insurance or as to which
the insurance carrier has denied its responsibility, and such judgment shall
continue unsatisfied and in effect for fifteen (15) consecutive days without a
stay of execution.

          Section 5.2 Remedies. Upon the occurrence and during the continuation
of a Termination Event, Buyer may take any of the following actions: (i) declare
the Termination Date to have occurred, whereupon the Termination Date shall
forthwith occur, without demand, protest or further notice of any kind, all of
which are hereby expressly waived by each Originator; provided, however, that
upon the occurrence of a Termination Event described in Section 5.1(d), or of an
actual or deemed entry of an order for relief with respect to any Originator
under the Federal Bankruptcy Code or under any other applicable bankruptcy,
insolvency, arrangement, moratorium or similar laws of any other jurisdiction
(foreign or domestic), the Termination Date shall automatically occur, without
demand, protest or any notice of any kind, all of which are hereby expressly
waived by each Originator and (ii) to the fullest extent permitted by applicable
law, declare that the Default Fee shall accrue with respect to any amounts then

provision of this Agreement, by operation of law, at equity or otherwise, all of
which are hereby expressly preserved, including, without limitation, all rights
and remedies provided under the UCC, all of which rights shall be cumulative.

          Section 6.1 Indemnities by the Originators. Without limiting any other
rights that Buyer may have hereunder or under applicable law, each Originator
hereby agrees to indemnify (and pay upon demand to) Buyer and its assigns (and

"Indemnified Party") from and against any and all damages, losses, claims,
taxes, liabilities, costs, expenses and for all other amounts payable, including

by any of them arising out of or as a result of this Agreement or the
acquisition, either directly or indirectly, by Buyer of an interest in the
Receivables of such Originator, excluding, however:

                    (x)  Indemnified Amounts to the extent a final judgment of a
     court of competent jurisdiction holds that such Indemnified Amounts

     Indemnified Party seeking indemnification;

                    (y)  Indemnified Amounts to the extent the same includes
     losses in respect of Receivables that are uncollectible on account of the

     Indemnified Party's principal executive office is located, on or measured
     by the overall net income of such Indemnified Party to the extent that the
     computation of such taxes is consistent with the characterization for
     income tax purposes of the acquisition by the Purchasers of Purchaser
     Interests under the Purchase Agreement as a loan or loans by the Purchasers
     to Buyer secured by, among other things, the Receivables, the Related
     Security and the Collections;

provided, however, that nothing contained in this sentence shall limit the
liability of any Originator or limit the recourse of Buyer to any Originator for
amounts otherwise specifically provided to be paid by such Originator under the
terms of this Agreement. Without limiting the generality of the foregoing
indemnification, each Originator shall indemnify Buyer for Indemnified Amounts
(including, without limitation, losses in respect of uncollectible receivables,
regardless of whether reimbursement therefor would constitute recourse to
Originator) relating to or resulting from:

                         (i)  any representation or warranty made by such
     Originator (or any officers of such Originator) under or in connection with
     this Agreement, any other Transaction Document or any other information or
     report delivered by such Originator pursuant hereto or thereto that shall
     have been false or incorrect when made or deemed made;

                         (ii) the failure by such Originator, to comply with any
     applicable law, rule or regulation with respect to any Receivable or
     Contract related thereto, or the nonconformity of any Receivable or
     Contract included therein with any such applicable law, rule or regulation
     or any failure of such Originator to keep or perform any of its

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

     related to or arising from this Agreement or any other Transaction
     Document, the transactions contemplated hereby, the use of the proceeds of
     any Purchase, the ownership of the Receivables of such Originator or any
     other investigation, litigation or proceeding relating to such Originator
     in which any Indemnified Party becomes involved as a result of any of the
     transactions contemplated hereby;

                         (viii) any inability to litigate any claim against any
     Obligor in respect of any Receivable of such Originator as a result of such
     Obligor being immune from civil and commercial law and suit on the grounds
     of sovereignty or otherwise from any legal action, suit or proceeding;

                         (ix)   any Termination Event described in
     Section 5.1(d);

                         (x)    any failure to vest and maintain vested in

     at the time of the Purchase or at any subsequent time;

                         (xii)  any action or omission by such Originator which

assigns) as its attorney(ies)-in-fact, to act on behalf of such Originator (i)
to authorize and/or execute on behalf of such Originator as debtor and to file

Receivables. This appointment is coupled with an interest and is irrevocable.

          Section 7.10  Integration; Binding Effect; Survival of Terms.

                    (a) This Agreement and each other Transaction Document
contain the final and complete integration of all prior expressions by the
parties hereto with respect to the subject matter hereof and shall constitute
the entire agreement among the parties hereto with respect to the subject matter
hereof superseding all prior oral or written understandings.

                    (b) This Agreement shall be binding upon and inure to the
benefit of each Originator and Buyer, and their respective successors and
permitted assigns (including any trustee in bankruptcy). No Originator may
assign any of its rights and obligations hereunder or any interest herein
without the prior written consent of Buyer. Buyer may assign at any time its
rights and obligations hereunder and interests herein to any other Person
without the consent of any Originator. Without limiting the foregoing, each
Originator acknowledges that Buyer, pursuant to the Purchase Agreement, may
assign to the Agent, for the benefit of the Purchasers, its rights, remedies,
powers and privileges hereunder and that the Agent may further assign such
rights, remedies, powers and privileges to the extent permitted in the Purchase
Agreement. Each Originator agrees that the Agent, as the assignee of Buyer,
shall, subject to the terms of the Purchase Agreement, have the right to enforce
this Agreement and to exercise directly all of Buyer's rights and remedies under
this Agreement (including, without limitation, the right to give or withhold any
consents or approvals of Buyer to be given or withheld hereunder) and each
Originator agrees to cooperate fully with the Agent in the exercise of such
rights and remedies. This Agreement shall create and constitute the continuing
obligations of the parties hereto in accordance with its terms and shall remain
in full force and effect until terminated in accordance with its terms;
provided, however, that the rights and remedies with respect to (i) any breach
of any representation and warranty made by the Originators pursuant to Article
II; (ii) the indemnification and payment provisions of Article VI; and (iii)
Section 7.5 shall be continuing and shall survive any termination of this
Agreement.

          Section 7.11  Counterparts; Severability; Section References. This
Agreement may be executed in any number of counterparts and by different parties
hereto in separate counterparts, each of which when so executed shall be deemed
to be an original and all of which when taken together shall constitute one and
the same Agreement. Any provisions of this Agreement which are prohibited or
unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective
to the extent of such prohibition or unenforceability without invalidating the
remaining provisions hereof, and any such prohibition or unenforceability in any
jurisdiction shall not invalidate or render unenforceable such provision in any
other jurisdiction. Unless otherwise expressly

receive, and Buyer shall make, any and all payments relating to any

Agent or any Purchaser under the Purchase Agreement.

1. Purpose

The purpose of the Patterson Dental Company 2001 Non-Employee Directors' Stock

increased Common Stock ownership by the members of the Board of Directors ("the
Board") of the Company who are Eligible Directors as defined in the Plan.

2. Administration

The Plan shall be administered by the Board. The Board shall have all the powers
vested in it by the terms of the Plan, such powers to include authority (within
the limitations described herein) to prescribe the form of the agreement
embodying awards of stock options made under the Plan ("Options"). The Board
shall, subject to the provisions of the Plan, grant Options under the Plan and
shall have the power to construe the Plan, to determine all questions arising
thereunder and to adopt and amend such rules and regulations for the
administration of the Plan as it may deem desirable. Any decision of the Board
in the administration of the Plan, as described herein, shall be final and
conclusive. The Board may act only by a majority of its members in office,
except that the members thereof may authorize any one or more of their number or
the Secretary or any other officer of the Company to execute and deliver
documents on behalf of the Board. No member of the Board shall be liable for
anything done or omitted to be done by such member or by any other member of the

400,000 shares, subject to adjustment as provided in Paragraph 6 below. In the
event that Options granted under the Plan shall terminate or expire without
being exercised in whole or in part, new Options may be granted covering the
shares not purchased under such lapsed Options.

4. Eligible Directors

The members of the Board who are eligible to participate in the Plan are persons
who serve as directors of the Company on or after the effective date of the Plan
and who are not current employees of the Company or any affiliate or subsidiary
of the Company.

5. Terms and Conditions of Options

Each Option granted under the Plan shall be evidenced by an agreement in such
form as the Board shall prescribe from time to time in accordance with the Plan
and shall comply with the following terms and conditions:

     (a)  The Option exercise price shall be the fair market value of the Common
          Stock shares subject to such Option on the date the Option is granted.

          follows:

          (i)  if the Common Stock is listed on a national securities exchange
               or admitted to unlisted trading privileges on such exchange, the
               fair market value on any

<PAGE>

                given day shall be the average of the high and the low sales
                price of a Common Stock share on such day or, if such exchange
                is closed on that date, on the last preceding date on which such
                exchange was open for trading;

          (ii)  if the Common Stock is not listed on a national securities
                exchange, the fair market value on any given day shall be the
                average of the high and the low sales prices of a Common Stock
                share on the Nasdaq National Market on such day or, if the
                Nasdaq National Market is closed on that date, on the last
                preceding date on which the Nasdaq National Market was open for
                trading;

          (iii) if the Common Stock is not listed on a national securities
                exchange, is not admitted to unlisted trading privileges on any
                such exchange, and is not eligible for inclusion on the Nasdaq
                National Market, the fair market value on any given day shall be
                the average of the closing representative bid and asked prices
                on such day, as reported on the Nasdaq National Market, and if
                not reported on such Market, then as reported by the National
                Quotation Bureau, Inc. or such other publicly available
                compilation of the bid and asked prices of the Common Stock in
                any over-the-counter market on which the Common Stock is traded;
                or

          (iv)  if there exists no public trading market for the Common Stock,
                the fair market value on any given day shall be an amount
                determined by the Board in such manner as it may reasonably
                determine in its discretion, provided that such amount shall not
                be less than the book value per share as reasonably determined
                by the Board as of the date of determination nor less than the
                par value of the Stock.

     (b)  Each year, as of the date of the annual meeting of shareholders of the
          Company, commencing with the 2002 annual meeting of the shareholders
          of the Company, each Eligible Director who has been elected or
          reelected or who is continuing as a member of the Board as of the
          adjournment of the annual meeting, shall automatically receive an
          Option award. The number of shares to be covered by an Option award to
          an Eligible Director who is elected to the Board for the first time,
          either by the shareholders of the Company or by the Board to fill a
          vacancy thereon, shall be 12,000 shares (an "Initial Grant"). The date
          of an Option award to a person first elected to the Board to fill a
          vacancy thereon shall be the date of such election. The number of
          shares to be covered by an Option award to an Eligible Director who is
          reelected to the Board or whose Board Membership is continuing
          following such annual meeting shall be 6,000 shares (an "Annual
          Grant"). The number of shares of any Option award shall be subject to
          adjustment as provided in Section 6. An Initial Grant shall also be
          awarded to an Eligible Director who is first elected to the Board
          prior to the Company's 2002 annual meeting, and who has not received
          the grant of a stock option under any other plan of the Company;
          provided, however, that if an Initial Grant is made within six months
          of an Annual Grant to which an Eligible Director would be entitled to
          receive, such Initial Grant shall be in lieu of the next succeeding
          Annual Grant.

     (c)  In addition to any Options received pursuant to Section 5(b), each
          Eligible Director shall automatically be granted the right to elect to
          receive additional Options in lieu of the amount of the director's
          annual fee such Eligible Director is entitled to receive ("Annual
          Retainer"), or a portion thereof, for the year following election or
          reelection to, or continuation on, the Board. Such election to receive
          additional Options shall be irrevocable and must be made in writing
          prior to the commencement of the period

                                       2

<PAGE>

          prior to which the Annual Retainer is to be earned. Options granted
          subject to such election shall be granted on the first day of the
          Company's fiscal year in which such Annual Retainer is earned. The
          number of additional Options such Eligible Director can obtain
          pursuant to this Section shall be determined pursuant to the following
          formula:

          Amount of Annual
          Retainer to be Converted          =   Options Granted in Lieu of
          Stock Price per share on Date of      Cash
          Grant x Valuation Discount

          The Valuation Discount shall be based upon the Black-Scholes formula
          or upon such other discount as the Board determines to be appropriate.

     (d)  No Option granted under the Plan shall be transferable by the optionee
          other than by will or by the laws of descent and distribution, and
          such Option shall be exercisable, during the optionee's lifetime, only
          by the optionee. Notwithstanding the foregoing, the Board may set
          forth in a stock option agreement, at the time of grant or thereafter,
          that Options may be transferred to trusts solely for the benefit of
          such immediate family members and to partnerships in which such family
          members and/or trusts are the only partners. For this purpose,
          immediate family means the optionee's spouse, parents, children,
          stepchildren, grandchildren and legal dependants. Any transfer of
          Options made under this provision will not be effective until notice
          of such transfer is delivered to the Company.

     (e)  No Option or any part of an Option shall be exercisable:

          (i)   except as provided in Section 5(h) and Section 6(b), before the
                Eligible Director has served one term-year as a member of the
                Board since the date the Option was granted (as used herein, the
                term "term-year" means that period from one Annual Meeting to
                the subsequent Annual Meeting),

          (ii)  after the expiration of ten years from the date the Option was
                granted, or after the expiration of one year following the date
                on which the Eligible Director to whom the Option was granted
                ceased to be an Eligible Director for any reason.

          (iii) unless written notice of the exercise is delivered to the
                Company specifying the number of shares to be purchased and
                payment in full is made for the shares of Common Stock being
                acquired thereunder at the time of exercise, such payment shall
                be made:

                (A) in United States dollars by certified check, or bank draft,
                    or

                (B) by tendering to the Company Common Stock shares owned by the
                    person exercising the Option and having a fair market value
                    equal to the cash exercise price applicable to such Option,
                    such fair market value to be the average of the high and low
                    sales prices of a Common Stock share on the date of exercise
                    as reported on the Nasdaq National Market or, if the Nasdaq
                    National Market is closed on that date, on the last
                    preceding date on which the Nasdaq National Market was open
                    for trading, or

                                       3

<PAGE>

               (C)  by a combination of United States dollars and Common Stock
                    shares as aforesaid, and

          (iv) unless the person exercising the Option has been, at all times
               during the period beginning with the date of grant of the Option
               and ending on the date of such exercise, an Eligible Director of
               the Company, except that if such person shall cease to be such an
               Eligible Director, for any reason, while holding an Option that
               has not expired and has not been fully exercised, such person, or
               in the case of death, the executors, administrators, legatees or
               distributes, as the case may be, at any time within one year
               after the date such person ceases to be such an Eligible Director
               (but in no event after the Option has expired under the
               provisions of subparagraph 5(e)(ii) above), may exercise the
               Option with respect to any Common Stock shares as to which such
               person has not exercised the Option on the date the person ceased
               to be such an Eligible Director.

               In the event any Option is exercised by the executors,
               administrators, legatees or distributees of the estate of a
               deceased optionee, the Company shall be under no obligation to
               issue stock thereunder unless and until the Company is satisfied
               that the person or persons exercising the Option are the duly
               appointed legal representatives of the deceased optionee's estate
               or the proper legatees or distributees thereof.

     (f)  Subject to subparagraph 5(e) above, an Option shall become exercisable
          in full beginning on the earlier of (a) the first anniversary date of
          the grant of the Option or (b) the completion of one term-year
          following the grant of the Option.

     (g)  Notwithstanding anything to the contrary herein, if an Option has been
          transferred in accordance with Section 5(d), the Option shall be
          exercisable solely by the transferee. The Option shall remain subject
          to the provisions of the Plan, including that it will be exercisable
          only to the extent that the optionee or optionee's estate would have
          been entitled to exercise it if the optionee had not transferred the
          Option. In the event of the death of the transferee prior to the
          expiration of the right to exercise the Option, the Option shall be
          exercisable by the executors, administrators, legatees and
          distributees of the transferee's estate, as the case may be, for a
          period of one year following the date of the transferee's death but in
          no event be exercisable after the expiration of the Option period set
          forth in the Stock Option Agreement. The Option shall be subject to
          such other rules or terms as the Board shall determine.

     (h)  In the case of an Initial Grant, one-third of such Option shall become
          exercisable on the first, second and third anniversaries of the date
          of grant, respectively.

6. Adjustment Upon Certain Events

     (a)  In the event of changes in the outstanding Common Stock of the Company
          by reason of any stock dividend, recapitalization, merger,
          consolidation, split-up, combination, exchange of shares, rights
          offering to purchase stock at a price substantially below market
          value, or the like, the aggregate number and kind of shares available
          under the Plan, and the number, kind and price of shares subject to
          outstanding Options, shall be appropriately adjusted by the Board,
          whose determination shall be conclusive.

                                       4

<PAGE>

     (b)  Upon the occurrence of a Change of Control, (i) all outstanding
          Options granted pursuant to the Plan, to the extent not theretofore
          exercised or canceled, shall become exercisable in full for the
          remainder of the applicable term of such Options, and (ii) all
          restrictions applicable to all outstanding Options granted pursuant to
          the Plan shall be deemed to have been satisfied and such Options shall
          immediately vest in full.

     (c)  Except as otherwise provided in an Option agreement, upon the
          occurrence of a Change of Control (as defined in Section 6(d)), the
          Board may, in its sole discretion, provide for (i) the payment of a
          cash amount in exchange for the cancellation of an Option which may
          equal the excess, if any, of the fair market value of the shares
          subject to such Option, as defined in Section 5(a), over the aggregate
          exercise price of such Options or (ii) the issuance of substitute
          Option awards that will substantially preserve the value, rights and
          benefits of any affected Options previously granted hereunder.

     (d)  "Change of Control" means any one of the following:

          (i)  Individuals who, as of September 10, 2001, constitute the Board
               of Directors of the Company (the "Incumbent Board"), cease for
               any reason to constitute at least a majority of such Board;
               provided, however, that any individual becoming a director
               subsequent to the date hereof, whose election, or nomination for
               election by the Company's shareholders, was approved by a vote of
               at least a majority of the Incumbent Board shall be considered as
               though such individual were a member of the Incumbent Board, but
               excluding, for this purpose, any such individual whose initial
               assumption of the office occurs as a result of an actual or
               threatened election contest with respect to the election or
               removal of directors or other actual or threatened solicitation
               of proxies or consents by or on behalf of a "person" (as such
               term is defined in Section 13(d) or 14(d) of the Securities
               Exchange Act of 1934, as amended from time to time) other than
               the Incumbent Board; or

          (ii) Consummation by the Company of a reorganization, merger or
               consolidation or sale or other disposition of all or
               substantially all of the assets of the Company (a "Business
               Combination"), in each case, unless, following such Business
               Combination, (A) all or substantially all of the individuals and
               entities who were the beneficial owners, respectively, of the
               then outstanding Shares of the Company (or its successor by
               merger, consolidation or purchase of all or substantially all of
               its assets) (the "Outstanding Common Stock") and the combined
               voting power of the then outstanding voting securities of the
               Company (or its successor by merger, consolidation or purchase of
               all or substantially all of its assets) entitled to vote
               generally in the election of directors (the "Outstanding Voting
               Securities") immediately prior to such Business Combination
               beneficially own, directly or indirectly, more than 50% of,
               respectively, the then Outstanding Common Stock and the combined
               voting power of the then Outstanding Voting Securities, as the
               case may be, of the corporation resulting from such Business
               Combination (including, without limitation, a corporation which
               as a result of such transaction owns the Company or all or
               substantially all of the Company's assets either directly or
               through one or more subsidiaries) in substantially the same
               proportions as their ownership immediately prior to such Business
               Combination of the Outstanding Common Stock and Outstanding
               Voting Securities, as the case may be, and (B) at least a
               majority of the members of the board of directors of the

                                       5

<PAGE>

                corporation resulting from such Business Combination were
                members of the Incumbent Board at the time of the execution of
                the initial agreement or of the action of such Incumbent Board
                providing for such Business Combination; or

          (iii) Approval by the shareholders of the Company of a complete
                liquidation or dissolution of the Company.

7. Miscellaneous Provisions

     (a)  Except as expressly provided for in the Plan, no Eligible Director or
          other person shall have any claim or right to be granted an Option
          under the Plan. Neither the Plan nor any action taken hereunder shall
          be construed as giving any Eligible Director any right to be retained
          in the service of the Company.

     (b)  Except as provided for under Section 5(d), an optionee's rights and
          interest under the Plan may not be assigned or transferred in whole or
          in part either directly or by operation of law or otherwise (except in
          the event of an optionee's death, by will or the laws of descent and
          distribution), including, but not by way of limitations, execution,
          levy, garnishment, attachment, pledge, bankruptcy or in any other
          manner, and no such right or interest of any participant in the Plan
          shall be subject to any obligation or liability of such participant.
          Any Options held by such assignee or transferee shall be subject to
          the terms of this Plan and the agreement pursuant to which such
          Options were granted.

     (c)  No Common Stock shares shall be issued hereunder unless counsel for
          the Company shall be satisfied that such issuance will be in
          compliance with applicable federal, state and other securities laws
          and regulations.

     (d)  It shall be a condition to the obligation of the Company to issue
          Common Stock shares upon exercise of an Option, that the optionee (or
          any beneficiary or person entitled to act under subparagraph 5(e)(iv)
          above) pay to the Company, upon its demand, such amount as may be
          requested by the Company for the purpose of satisfying any liability
          or obligation of the Company to withhold federal, state, local or
          foreign income or other taxes. If the amount requested is not paid,
          the Company may refuse to issue Common Stock shares.

     (e)  The expenses of the Plan shall be borne by the Company.

     (f)  The Plan shall be unfunded. The Company shall not be required to
          establish any special or separate fund or to make any other
          segregation of assets to assure the issuance of shares upon exercise
          of any Option under the Plan and issuance of shares upon exercise of
          Options shall be subordinate to the claims of the Company's general
          creditors.

     (g)  By accepting any Option or other benefit under the Plan, each optionee
          and each person claiming under or through such person shall be
          conclusively deemed to have indicated his acceptance and ratification
          of, and consent to, any action taken under the Plan by the Company or
          the Board.

                                       6

8. Amendment

The Plan may be amended at any time and from time to time by the Board as the
Board shall deem advisable, including, but not limited to amendments necessary
to qualify for any exemption or to comply with applicable law or regulations
provided, however, that except as provided in Paragraph 6 above, the Board may
not, without further approval by the shareholders of the Company in accordance
with Paragraph 10 below, increase the maximum number of shares of Common Stock
as to which Options may be granted under the Plan, increase the number of shares
subject to an Option, reduce the minimum Option exercise price described in
subparagraph 5(a) above, extend the period during which Options may be granted
or exercised under the Plan or change the class of persons eligible to receive
Options under the Plan. No amendment of the Plan shall materially and adversely
affect any right of any optionee with respect to any Option theretofore granted
without such optionee's written consent.

9. Termination

This Plan shall terminate upon the earlier of the following dates or events to
occur:

     (a)  upon the adoption of a resolution of the Board terminating the Plan;
