PRINCETON DENTAL MANAGEMENT CORPORATION

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

Under the terms of the transaction, the Company issued a warrant to
purchase 100 shares of Series B Preferred Stock. The Series B Preferred
Stock entitles Amsterdam Equities Limited (Amsterdam), after the
occurrence of an event of default, to elect a Class B director who would
have super-majority voting powers on the Company's Board of Directors.

The Convertible Debt and Preferred Stock may be converted into common
stock of the Company, at the sole option of the Investor Group, at
various conversion rates as set forth in the conversion formula
contained in the Financing Arrangements. Conversion pursuant to such
conversion formula would result in a conversion price per share of the
Company's common stock significantly below present market levels.

In addition, pursuant to the terms of the Financing Arrangements, the
Company issued to the holders of the Convertible Debt and the Preferred
Stock warrants to purchase shares of common stock at an exercise price
of $.50 per share (subsequently reduced to $.05 per share, subject to
adjustment, under the terms of the Modification Agreement). The Investor
Group may exercise the warrants only upon the occurrence of an event of
default under the terms of certain minimum financial goals, as defined
in the Financing Arrangements. As of December 31, 1997, the Company was
in default under the Financing Agreement and the stated financial goals
were not met, and, accordingly, the default warrants are exercisable by
the Investor Group upon payment of the exercise price. Should the
Company cure the default and meet the minimum financial goals, the
default warrants would not be exercisable. The cumulative effect of the
issuance of shares pursuant to the default warrant and conversion of all
Convertible Debt and Preferred Stock could result in ownership by the
Investor Group of approximately 85% of the Company's total issued and
outstanding common stock. To date, the Investor Group has taken no steps
to exercise these default warrants.

In August 1996, the Company entered into a Letter Agreement by and among
the Company, ▇▇. ▇▇▇▇▇▇▇ ▇. ▇▇▇▇▇▇▇▇, a former President of the Company;
the former Consultants to the Company, certain directors of the Company
and the Investor Group. Under the Letter Agreement, the Series B
Preferred Stock was amended to be immediately effective and Class B
Preferred Stock was issued to Amsterdam. The Class B Preferred Stock
entitled Amsterdam to elect a Director to the Board of Directors of the
Company who would have super majority voting powers. In effect, the
Class B director appointed by Amsterdam shall have the number of votes
on the Board of Directors as the current Board currently holds, plus one
vote. The amendment and activation of the Class B Preferred Stock
occurred upon the satisfaction of the following two conditions: (i)
delivery to the Company of a notice, pursuant to which the Investor
Group would convert an aggregate amount of $700,000 of currently
outstanding Convertible Debt and Preferred Stock into the Company's
Common Stock in accordance with the contractual terms of the Financing
Arrangements and (ii) upon the advance to the Company of an additional
$200,000 pursuant to the Financing Arrangements.

PRINCETON DENTAL MANAGEMENT CORPORATION

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

In connection with the issuance of the Class B Preferred Stock, the
provision of additional funding and conversion of debt, the Consultants
and certain directors of the Company agreed to forfeit, on a pro rata
basis, an aggregate amount of 60,000 options and warrants to purchase
the Company's Common Stock.

Pursuant to a Modification Agreement (Modified Agreement) entered into
between the Investor Group and the Company dated July 1, 1997, the
Investor Group agreed, conditioned upon continued listing by the Company
on the Nasdaq SmallCap Market and similar concessions by another
significant Company creditor, to waive all accumulated and ongoing
interest and/or dividends on the Convertible Debt/Preferred Stock for
the period from January 1, 1997 through December 31, 1997.

The Convertible Debt is secured by substantially all assets of the
Company and requires the Company to comply with certain financial and
non-financial debt covenants.

At December 31, 1997, the Company was in violation of certain debt
covenants. As such, the Company has classified the Convertible Debt as a
current liability. To date, the Investor Group has not made formal claim
under the debt covenant violation.

(15) GOING CONCERN

As shown in the accompanying consolidated financial statements, the
Company has incurred minimal profit and recurring losses from operations
resulting in cash flow problems. Additionally, the Company is in default
with regards to the Convertible Debt. To date, the Investor Group has
not demanded payment. These factors raise doubt about the Company's
ability to continue as a going concern.

Management has instituted a cost reduction program, has sold
economically inefficient practices and is emphasizing operational
efficiencies. In addition, the Financing Arrangements (Note 14), could,
at the discretion of the Investor Group, provide adequate funds for
working capital, debt refinancing and future acquisitions. Additional
funding from the Investor Group, however, cannot be assured.

(16) SUBSEQUENT EVENT

During fiscal year 1997, the Company failed to meet certain financial
covenants related to the Financing Arrangements which has resulted in
the ability of the Investor Group to exercise warrants to purchase
approximately 1,000,000 shares of common stock at approximately $.05 per
share effective January 1, 1998 (Note 14). To date, the Investor Group
has not formally indicated an intent to exercise these warrants.

RECITALS

AGREEMENTS

NOW, THEREFORE, for good and valuable consideration, the receipt and

1. Unless otherwise defined herein, all capitalized terms used

▇▇▇▇▇▇▇▇ ▇▇▇▇▇▇ ▇▇▇▇▇▇ Dollars (US $150,000.00). In full and final consideration
for such reduction and forgiveness of debt, PDMC agrees to proceed to
immediately issue 53,381 shares of PDMC Common Stock (the "Stock") to the
Constituent Shareholders. The Stock shall not be registered under the Securities
Act of 1933 or any state securities laws, and shall be restricted stock issued
pursuant to an applicable exemption from registration. The Stock shall be an
aggregate of 53,381 shares, but shall otherwise be issued to such individuals

during the Waiver Period and interest shall not accrue during the Waiver Period.
Provided, however, that the parties acknowledge that this Amendment is being
entered into, in part, in consideration of a waiver, subject to certain terms
and conditions, of accrued and ongoing interest by Amsterdam Equities Limited

period from January 1, 1997 through December 31, 1997 ("Group Interest Waiver"),
and, in the event that the Group Interest Waiver fails to occur, than, in such
event, the Holder may, upon thirty (30) days written notice to the Maker,
declare this Amendment terminated effective as of the effective date of such
notice."

Except as specifically amended by this Amendment, the Acquisition
Promissory Note shall remain in full force and effect.

This Amendment may be executed in counterparts.

IN WITNESS WHEREOF, the parties have executed this Allonge and Fifth
Amendment to Acquisition Promissory Note as of the date first written above.

AGREEMENT OF PURCHASE AND SALE

THIS AGREEMENT made as of the 1st day of May, 1997 by and between
Princeton Medical Management Northeast, Inc., a Florida corporation (the
"Seller"), and Valley Forge Dental Associates, Inc., a Delaware corporation (the
"Purchaser").

W I T N E S S E T H:

WHEREAS, the Seller, together with Century Dental Center, P.C., a
Pennsylvania professional corporation ("Century Dental"), is engaged in the
business of operating and managing a dental practice under the name "Century
Dental Center" which provides dental services and related activities at one (1)
facility in the city of Springfield in the Commonwealth of Pennsylvania (such
activities being hereinafter referred to as the "Business"); and

WHEREAS, the Purchaser (or its designee) desires to acquire from the
Seller certain assets of the Seller described in Section I(C)(i) hereof (the
"Assets") and to assume certain liabilities and contractual obligations of the
Seller as described in Section I(C)(ii) hereof (the "Assumed Liabilities"), and
the Seller desires to sell or assign the Assets and to assign the Assumed
Liabilities to the Purchaser (or its designee), on the terms and subject to the
conditions hereinafter set forth.

NOW, THEREFORE, in consideration of the premises and the mutual
covenants and agreements hereinafter set forth, and intending to be legally
bound, the parties hereto hereby agree as follows:

SECTION I

PURCHASE AND SALE OF THE ASSETS

A. Purchase and Sale of the Assets. Subject to the terms and
conditions of this Agreement and on the basis of the representations,
warranties, covenants and agreements herein contained, at the Closing (as
hereinafter defined):

(i) The Seller agrees to sell, assign and convey to the
Purchaser (or its designee), and the Purchaser (or its designee) agrees to
purchase, acquire and accept from the Seller, the Assets.
10
2

(ii) The Seller agrees to assign to the Purchaser (or its
designee) and the Purchaser (or its designee) agrees to accept and assume from
the Seller, the Assumed Liabilities. The Purchaser (and its designee) shall not
assume and shall have no responsibility with respect to, and shall be
indemnified by the Seller against any and all liabilities or obligations of the
Seller, other than the Assumed Liabilities.

B.Purchase Price. The purchase price (the "Purchase Price")
for the Assets is (i) $355,109.38 and (ii) the contingent payments, if earned
(the "Contingent Payments"), provided for in Section I(D) hereof. The Purchase
Price payable at the Closing shall be made by (a) delivery to the Seller of
$234,585.87 in immediately available funds by means of a wire transfer to an
account designated by the Seller, (b) at the direction of the Seller, delivery
to First Republic Bank ("First Republic") of $61,655.25 in immediately available
funds by means of a wire transfer to an account designated by First Republic,
(c) at the direction of the Seller, delivery to ▇▇▇▇▇▇▇▇ ▇. ▇▇▇▇, D.D.S., P.C.
f/k/a Century Dental Center I, P.C. ("Century") of $29,434.13 in immediately
available funds by means of a wire transfer to an account designated by Century
and (d) delivery of an 8% promissory note of the Purchaser in the principal
amount of $29,434.13 in the form of Exhibit A attached hereto.

C. Assets; Assumed Liabilities.

(i) The Assets shall consist of all assets, business,
contract rights, patient records, financial books and financial records, other
books and records and good will, of every kind and nature, real, personal, and
mixed, tangible and intangible, wherever located, of the Seller used in or in
any way related to the Business as conducted by the Seller, including, but not
limited to, inventory and supplies, prepaid expenses, deposits, tradenames,
trademarks, patents, copyrights, inventions, books and records, patient files,
and all other agreements and arrangements necessary for the uninterrupted and
continuing operation of the Business, except for the assets listed in Schedule I
hereto (the "Excluded Assets").

(ii) The Assumed Liabilities shall consist of and shall be
limited solely to the obligations and liabilities of the Seller incurred in
connection with the Business listed in Schedule II hereto. The Purchaser (and
its designee) shall not assume, shall have no responsibility with respect to,
and shall be indemnified, by the Seller against any liabilities or obligations
of the Seller or the
11
3

Business, except for the Assumed Liabilities set forth in Schedule II hereto.
The Seller shall remain liable for, and shall pay when due, any and all
obligations and liabilities of the Seller and the Business other than the
Assumed Liabilities.

(iii) It is specifically understood and agreed that the
Assumed Liabilities shall not include (a) liabilities of the Seller or the
Business for expenses incurred or accrued, at any time, in connection with the
transactions contemplated by this Agreement or in any other connection not in
the ordinary course of business, (b) liabilities of the Seller or the Business
for federal, state and municipal income, sales, franchise and other taxes,
including any interest, penalties and assessments thereon, and (c) liabilities
of the Seller or the Business arising out of or relating to any governmental or
private payor claims, returns, invoices, cost reports, late filings or billing
practices which relate to any period prior to the date of Closing. Neither the
Purchaser nor any designee of the Purchaser assuming the Assumed Liabilities
shall assume any liabilities of the Seller or the Business in connection with
any understanding or agreement, whether written or oral, with respect to any
retirement plan, including, but not limited to, any profit sharing, 401(k) or
defined benefit plan (as defined in Section 414(j) of the Internal Revenue Code
of 1986, as amended (the "Code").

D. Contingent Payments. Each of the Seller and the Purchaser
acknowledges and agrees that since the Business has a short operating history,
the full value of the Business on the date of the Closing is difficult to
ascertain with any degree of certainty on the date of Closing. Accordingly, the
parties to this Agreement agree that it is appropriate to provide for the
Contingent Payments set forth in this Section I(D) to reflect more accurately
the full value of the Business on the date of Closing. Subject to the conditions
set forth herein and in Schedule III hereto, within thirty (30) days after May
31, 1997 and, May 31, 1998, the Purchaser shall deliver to the Seller, the
Contingent Payments, if any, payable with respect to the twelve-month periods
ending May 31, 1997 and May 31, 1998, respectively. The amount of the Contingent
Payments payable to the Seller with respect to each such twelve-month period
(each, a "Contingent Period") (i) shall be based upon the achievement by the
Contingent Payment Business (as hereinafter defined) of targeted "net operating
revenues" (as hereinafter defined) during such Contingent Period and (ii) shall
be determined in accordance with the provisions hereof and Schedule III hereto.
Each of the Contingent Payments, if earned, shall be made by delivery to
12
4

the Seller of bank checks payable to the order of the Seller in such amounts of
cash as is determined in accordance with Schedule III hereto.

E. Computation of Net Operating Revenues. The Purchaser shall,
within thirty (30) days after the end of each Contingent Period, compute the
amount of the net operating revenues of the Contingent Payment Business for such
Contingent Period. The amount so computed shall be the net operating revenues
for purposes of determining whether or not Contingent Payments shall be due and
payable. Notwithstanding the determination of net operating revenues for any
applicable period by the Purchaser, the Seller shall receive the information
upon which such determination was made, and shall, in the event of a dispute as
to the amount or method of calculation of such net operating revenues have the
right to review all work papers relating to the determination of net operating
revenues. For purposes of this Agreement, (i) "net operating revenues" of the
Contingent Payment Business shall mean gross charges billed for all services
provided by the Contingent Payment Business, including capitation revenues
pursuant to prepaid dental plans (or, in the event that all or substantially all
of the assets and business of the Contingent Payment Business, shall have been
transferred to another entity or entities, the allocable portion of the gross
charges of such other entity or entities attributable to the Contingent Payment
Business) during the applicable Contingent Period less any necessary adjustments
to reflect patient refunds and amounts which are determined to be uncollectible
at the time of billing (contractual allowances) or in the future (billing
errors) as determined in accordance with generally accepted accounting
principles consistent with the Purchaser's accounting practices.

For purposes of Sections I(D) and I(E) hereof and Schedule III
hereto, the term "Contingent Payment Business" shall mean the operations,
services and activities of the Business as operated by the Purchaser (or its
designee) combined with the operations of any related professional corporation
managed by the Purchaser (or its designee) as such operations relate to the
Business.

F. Allocation. The Purchase Price (including the Assumed
Liabilities) shall be allocated as set forth in Schedule IV hereto. The parties
hereto agree that the allocation of the Purchase Price is intended to comply
with the allocation method required by Section 1060 of the Code. The parties
shall cooperate to comply with all substantive and procedural requirements of
Section 1060 of the Code and any regulations thereunder, and the allocation
shall be
13
5

adjusted if, and to the extent, necessary to comply with the requirements of
Section 1060 of the Code. Neither the Purchaser nor the Seller will take or
permit any affiliated person to take, for federal, state or local income tax
purposes, any position inconsistent with the allocation set forth in Schedule IV
hereto, or, if applicable, such adjusted allocation. Each of the Purchaser and
the Seller agrees that each of them shall attach to its tax returns for the tax
year in which the Closing shall occur an information statement on Form 8594,
which shall be completed in accordance with allocations set forth in Schedule IV
hereto.

G. Assignment. The parties hereto agree that the Purchaser may
designate one or more direct or indirect wholly owned subsidiaries of the
Purchaser to acquire the Assets and to assume the Assumed Liabilities; provided,
however, that the Purchaser's payment obligations hereunder shall not be
affected by any such designations by the Purchaser.

SECTION II

REPRESENTATIONS, WARRANTIES, COVENANTS
AND AGREEMENTS OF THE SELLER

The Seller hereby represents and warrants to, and covenants
and agrees with, the Purchaser, as of the date hereof and as of the date of the
Closing, that:

A. Organization and Qualification. The Seller is duly
organized, validly existing and in good standing under the laws of the State of
Florida, is duly qualified to do business in the Commonwealth of Pennsylvania,
and has full corporate power and authority to own its properties and to conduct
the Business. The Seller has full power, authority and legal right and all
necessary approvals, permits, licenses and authorizations to own its properties
and to conduct the Business and to enter into and consummate the transactions
contemplated under this Agreement, except for such approvals, permits, licenses
and authorizations, the absence of which would not have a material adverse
effect on the business, financial condition, operations or prospects of the
Business taken as a whole (a "Material Adverse Effect"). The copies of the
certificate of incorporation and by-laws of the Seller which have been delivered
to the Purchaser are complete and correct.

B. Authority. The execution and delivery of this Agreement by
the Seller, the performance by the Seller of its covenants and agreements
hereunder and the
14
6

consummation by the Seller of the transactions contemplated hereby have been
duly authorized by all necessary corporate action. This Agreement constitutes a
valid and legally binding obligation of the Seller, enforceable against the
Seller in accordance with its terms, except as enforceability may be limited by
bankruptcy, insolvency, reorganization or other similar laws affecting
creditors' rights generally or by general principles of equity.

C. No Legal Bar; Conflicts. Neither the execution and delivery
of this Agreement, nor the consummation of the transactions contemplated hereby,
violates any provision of the certificate of incorporation or by-laws of the
Seller or any statute, ordinance, regulation, order, judgment or decree of any
court or governmental agency or board, or conflicts with or will result in any
breach of any of the terms of or constitute a default under or result in the
termination of or the creation of any lien pursuant to the terms of any contract
or agreement to which the Seller is a party or by which the Seller or any of the
Assets is bound, except where such violation, conflict, breach, default,
termination, or lien creation would not have a Material Adverse Effect. No
consents, approvals or authorizations of, or filings with, any governmental
authority or any other person or entity are required in connection with the
execution and delivery of this Agreement, the consummation of the transactions
contemplated hereby and the operation of the Business by the Purchaser (or its
designee) subsequent to the Closing, except for required consents, if any, to
assignment of contracts, leases and other agreements as set forth in Exhibit B.

D. Financial Statements; No Undisclosed Liabilities. The
Seller has delivered to the Purchaser the balance sheets of the Business as of
December 31, 1995 and December 31, 1994, and the income statements for the
six-month period ended March 31, 1997, the nine-month period ended September 30,
1996, and the twelve-month period ended December 31, 1995 and December 31, 1994,
which financial statements (collectively, the "Financial Statements") were
internally prepared. The Financial Statements are true and correct in all
material respects and have been prepared in accordance with generally accepted
accounting principles applied consistently throughout the periods involved. The
Financial Statements fully and fairly present the financial condition of the
Business as at the dates thereof and the results of the operations of the
Business for the periods indicated. Except to the extent set forth in or
provided for in the Financial Statements or as identified in Exhibit B, and
except for current liabilities incurred in
15
7

the ordinary course of business consistent with past practices (and not
materially different in type or amount), the Seller, with respect to the
Business, has no liabilities or obligations of any nature, whether accrued,
absolute, contingent or otherwise, whether due or to become due, whether
properly reflected under generally accepted accounting principles as a liability
or a charge or reserve against an asset or equity account, and whether the
amount thereof is readily ascertainable or not. The Seller is not aware of any
material omissions in the Financial Statements. A true and correct copy of the
Financial Statements is attached hereto as Exhibit C.

E. Absence of Certain Changes. Except as set forth in Exhibit
B, subsequent to March 31, 1997, there has not been any (i) adverse or
prospective adverse change in the condition of the Business, financial or
otherwise, or in the results of the operations of the Seller, in connection with
the Business which has or could reasonably be expected to result in a Material
Adverse Effect; (ii) damage or destruction (whether or not insured) affecting
the properties or business operations of the Seller, in connection with the
Business, or the Assets; (iii) labor dispute or, to the best of the knowledge of
the Seller, threatened labor dispute involving any of the employees of the
Business, or any resignations, or to the best of the knowledge of the Seller,
threatened resignations of dentists, orthodontists, or other professional
employees, or notice that dentists, orthodontists, or other professional
employees intend to take leaves of absence, with or without pay; (iv) actual or,
to the best of the knowledge of the Seller, threatened disputes pertaining to
the Business with any major accounts or referral sources of the Business, or
actual or, to the best of the knowledge of the Seller, threatened loss of
business from any of the major accounts or referral sources of the Business,
except where such disputes or losses would not have a Material Adverse Effect;
(v) changes in the methods or procedures for billing or collection of customer
accounts or recording of customer accounts receivable or reserves for doubtful
accounts with respect to the Business; or (vi) other event or condition, known
to the Seller or which in the exercise of reasonable diligence should be known
to the Seller, not disclosed in this Agreement pertaining to and adversely
affecting the Assets or the Business.

F. No Dividends, Loans, Etc. Except as set forth in Exhibit B,
subsequent to March 31, 1997, the Seller has not, except in the normal course of
business, paid or discharged any outstanding indebtedness. Subsequent to March
31, 1997, the Seller, in connection with the Business,
16
8

has paid all normal and recurring installments (i) of bank indebtedness, (ii)
under leases and contractual obligations and (iii) of other amounts due and
payable to any persons. Subsequent to March 31, 1997, the Seller has not, in the
conduct of the Business, incurred any bank indebtedness, entered into any
leases, loan agreements or contracts, obligations or arrangements for the
payment of money or property to any person, or permitted any liens or
encumbrances to attach to any of its assets.

G. Real Property Owned or Leased. A list and brief description
of all real property owned by or leased to or by the Seller in connection with
the Business or in which the Sellers in the conduct of the Business, has any
interest is set forth in Exhibit B. All such leased real property is held
subject to written leases or other agreements (a description of which, including
the expiration date of all leases, is set forth in Exhibit B) which are valid
and effective in accordance with their respective terms, and there are no
existing defaults or events of default, or events which with notice or lapse of
time or both would constitute defaults, thereunder on the part of the Seller in
the conduct of the Business, except for such defaults, if any, which would not
have a Material Adverse Effect. The Seller has no knowledge of any default or
claimed or purported or alleged default or state of facts which with notice or
lapse of time or both would constitute a default on the part of any other party
in the performance of any obligation to be performed or paid by such other party
under any lease referred to in Exhibit B, except where the failure to have good
and valid title would not have a Material Adverse Effect. The Seller has not
received any written or oral notice to the effect that any lease will not be
renewed at the termination of the term thereof or that any such lease will be
renewed only at a substantially higher rent.
17
9

H. Title to Assets; Condition of Property. The Seller has good
and valid title to the Assets owned by it (in the case of owned real property
and the improvements thereon, good and marketable title in fee simple)
including, without limitation, the properties and assets reflected in the
Financial Statements (except for assets leased under leases set forth in Exhibit
B, inventory and other assets sold or retired and accounts receivable collected
upon, since March 31, 1997 in the ordinary course of business consistent with
past practices), free and clear of all liens, charges, encumbrances, security
interests or claims whatsoever, except as set forth in Exhibit B. The Seller has

covenants and conditions of this Agreement to be complied with and performed by

SECTION VIII

INDEMNIFICATION

A. Indemnification by the Seller. The Seller shall indemnify
and hold harmless the Purchaser from and against all losses, claims, taxes,
assessments, demands, damages, liabilities, obligations, costs and/or expenses
(hereinafter referred to collectively as the "Purchaser's Damages"), including,
without limitation, Purchaser's Counsel Expenses (as hereinafter defined),
sustained or incurred by the Purchaser (or its designee) in any action, claim or
proceeding (i) between the Purchaser and the Seller or (ii) between the
Purchaser and any third party or (iii) otherwise (a) arising out of or relating
to the breach of any of the obligations, covenants or provisions of, or the
inaccuracy of any of the representations or warranties made by the Seller herein
or (b) arising out of or relating to any liabilities or obligations of the
Seller which are not Assumed Liabilities including, without limitation, any and
all sales, use, transfer, corporate, payroll, and/or business and mercantile
taxes, penalties, and interest, owed to the Commonwealth of Pennsylvania and/or
▇▇▇▇▇▇ Township, and any and all fees incurred in connection with the Assignment
of Lease. For purposes hereof, "Purchaser's Counsel Expenses" shall mean
reasonable fees and disbursements of counsel howsoever sustained or incurred by
the Purchaser (or its designee), including, without limitation, in any action or
proceeding between the Purchaser and any third party. In addition to the right
of the Purchaser to indemnification hereunder, the Purchaser shall have the
right from time to time to set off the amount of any of the Purchaser's Damages
that the Purchaser is entitled to indemnification thereof against any Contingent
Payments. In the event that the Purchaser exercises its right under this Section
VIII(A) to set off the amount of any of the Purchaser's Damages against any
Contingent Payment and the Seller disputes the validity of the Purchaser's
Damages, the Purchaser agrees to place such disputed amount in an escrow account
to be held by ▇▇▇▇▇▇ & ▇▇▇▇▇▇ until the dispute is resolved pursuant to the
terms of this Section VIII(A) and Section XI(F) hereof. Any amounts set off by
the Purchaser which are later awarded to the Seller in accordance with Section
XI(F) hereof shall accrue interest at a rate of 8% per annum from the time of
any such set off and shall include reasonable fees and disbursements of counsel
incurred by the Seller.
38
30

B. Indemnification by the Purchaser. The Purchaser shall
indemnify and hold harmless the Seller from and against any and all losses,
claims, assessments, demands, damages, liabilities, obligations, costs and/or
expenses (hereinafter referred to collectively as the "Seller's Damages"; the
Seller's Damages and the Purchaser's Damages are sometimes referred to herein as
the "Damages"), including, without limitation, Seller's Counsel Expenses (as
hereinafter defined) sustained or incurred by the Seller in any action or
proceeding between (i) the Seller and the Purchaser or (ii) the Seller and any
third party or (iii) otherwise (a) by reason of the breach of any of the
obligations, covenants or provisions of, or the inaccuracy of any of the
representations or warranties made by, the Purchaser herein, or (b) arising out
of or relating to any liabilities or obligations which are Assumed Liabilities.
For purposes hereof, "Seller's Counsel Expenses" shall mean reasonable fees and
disbursements of counsel howsoever sustained or incurred by the Seller,
including, without limitation, in any action or proceeding between the Seller
and the Purchaser or in any action or proceeding between the Seller and a third
party.

C. Procedure for Indemnification. In the event that any party
hereto shall incur (or anticipates that it may incur in the case of third party
claims) any Damages in respect of which indemnity may be sought by such party
pursuant to this Section VIII, the party indemnified hereunder (the
"Indemnitee") shall notify the party or parties providing indemnification (the
"Indemnitor") promptly; in the case of third party claims, such notice shall in
any event be given within thirty (30) days of the filing or assertion of any
claim against the Indemnitee stating the nature and basis of such claim;
provided, however, that any delay or failure to notify any Indemnitor of any
claim shall not relieve it from any liability except to the extent that the
Indemnitor demonstrates that the defense of such action is materially prejudiced
by such delay or failure to notify. In the case of third party claims, the
Indemnitor shall, within ten (10) days of receipt of notice of such claim,
notify the Indemnitee of its intention to assume the defense of such claim at
its own expense. If the Indemnitor shall not assume the defense of any such
claim or litigation resulting therefrom, the Indemnitee may defend against any
such claim or litigation in such manner as it may deem appropriate and the
Indemnitee may settle such claim or litigation on such terms as it may deem
appropriate. In the event that a dispute arises concerning the obligation of the
Indemnitor to assume the defense of a claim, or a dispute arises concerning a
claim hereunder which does not involve a third party claim, or in
39
31

the event that there is any other dispute relating to indemnification, the
parties shall submit any such dispute to arbitration pursuant to Section XI(F)
hereof; provided, however, that the parties agree to negotiate in good faith for
a period of at least sixty (60) days prior to initiating arbitration to resolve
any dispute. If it shall be finally determined that the Indemnitor failed to
assume the defense of any claim for which the Indemnitor is liable to the
Indemnitee for Damages, then the expense of defending the claim shall be borne
by the Indemnitor. Payment of the Damages shall be made within ten (10) days of
a final determination of a claim.

A final determination of a claim shall be (i) a judgment of
any court determining the validity of a disputed claim, if no appeal is pending
from such judgment or if the time to appeal therefrom has elapsed, (ii) an award
of any arbitration determining the validity of such disputed claim, it there is
not pending any motion to set aside such award or if the time within which to
move to set such award aside has elapsed, (iii) a written termination of the
dispute with respect to such claim signed by all of the parties thereto or their
attorneys, (iv) a written acknowledgement of the Indemnitor that he or it no
longer disputes the validity of such claim, or (v) such other evidence of final
determination of a claim as shall be acceptable to the parties.

to take promptly all necessary steps (as set forth in such notice) to carry out

Agreement, the balance of which shall continue to be binding upon the parties
hereto with any such modification to become a part hereof and treated as though
