Note 1 - SIGNIFICANT ACCOUNTING POLICIES

The accounting policies followed by Princeton Dental Management Corporation
(the Company) for quarterly financial reporting purposes are the same as those
disclosed in the Company's annual financial statements.  In the opinion of
management, the accompanying condensed consolidated financial statements
reflect all adjustments necessary for a fair presentation of the information
presented.

The quarterly condensed consolidated financial statements herein have been
prepared by the Company without audit. Certain information and footnote
disclosures included in financial statements prepared in accordance with
generally accepted accounting principles have been condensed or omitted.
Although the Company's management believes the disclosures are adequate to make
the information not misleading, it is suggested that these quarterly condensed
financial statements be read in conjunction with the audited annual financial
statements and footnotes thereto.

Note 2 - RECLASSIFICATIONS

The accompanying condensed consolidated financial statements contain certain
reclassifications of previously reported information.  The reclassifications
have been made to more appropriately reflect the operating results of the
Company.

Note 3 - FINANCING AGREEMENT

1. On April 22, 1996, the Company entered into a financing arrangement pursuant
to which the Company issued Convertible Debt (the Convertible Debt) to
Amsterdam Equities Limited in the amount of $2,483,620 and 3,599.77 shares of
Series A 11.75% Cumulative Convertible Preferred Stock (the Preferred Stock) to
Amsterdam Equities Limited (195 shares), Frank Leonard Laport (1,904.77
shares), and Beverly Trust Company, as custodian for the Frank Leonard Laport
Rollover Individual Retirement Account No. 75-49990 (1,500 shares)
(collectively, the Investor Group).  The Convertible Debt and Preferred Stock
replaced indebtedness of the Company at April 22, 1996, in the amount of
$1,976,700 incurred under that certain letter agreement dated December 7, 1994
(the Letter Agreement) and that certain Secured Revolving Demand Note dated
January 27, 1995 (the Secured Note). Under the terms of the Convertible Debt
and Preferred Stock Agreements (also referred to herein collectively as the
Financing Arrangement) the Investor Group may lend additional funds, in
increments to be determined solely by the Investor Group. The Convertible Debt
and Preferred Stock were initially to bear interest and have a coupon rate,
respectively of 11.75%, plus the payment of any withholding taxes which might
be due and owing with respect to any person which is a foreign entity.
Payments on the Convertible Debt/Preferred Stock were interest only due in
quarterly installments which were to begin in September 1996.  The Convertible
Debt/Preferred Stock originally had a maturity of seven years from the date of
closing, subject to acceleration in the event of a default.  Subsequent to
September 30, 1996 the Company was unable to pay the interest only requirements
of the Convertible Debt and Preferred Stock Agreements, therefore, effective
October 1, 1996 until the accrued interest is paid, interest began to accrue at
the default rate of 21.75%. The accrued interest on the Convertible
Debt/Preferred Stock totaled approximately $563,112 at June 30, 1997.

Pursuant to that certain Modification Agreement ("Modification Agreement")
entered into between the Investor Group and the Company and dated as of July 1,
1997, the Investor Group has 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 (see Item 5 and Exhibit 10.55).

                    PRINCETON DENTAL MANAGEMENT CORPORATION
                 Notes to the Consolidated Financial Statements
                                 June 30, 1997
                                  (Unaudited)



Assuming this waiver continues through December 31, 1997, this waiver on the
part of the Investor Group will result in a total savings to the Company in
excess of $700,000.

In addition to the amounts owed under the Letter Agreement and the Secured
Note, the terms of the Convertible Debt and Preferred Stock Agreements called
for the conversion of 291,667 shares of the Company's Regulation D stock held
by the Investor Group into $350,000 of Convertible Debt and Preferred Stock.
The shares of common stock redeemed are being held in treasury at June 30,
1997.

An additional provision of the Convertible Debt and Preferred Stock Agreements
included the payment of $300,000 as a closing fee and required the Company to
reimburse the legal fees and costs and expenses of the Investor Group in
connection with the negotiation and the closing of the transaction which
totaled $216,897. The closing fees and reimbursement of the costs and expenses
were payable in the form of Convertible Debt and Preferred Stock. In total, the
Company incurred costs of $544,716 in connection with the refinancing which has
been capitalized and will be amortized over a period of seven years or until
the Convertible Debt/Preferred Stock is called.

The terms of the Convertible Debt and Preferred Stock Agreements provided the
Investor Group with certain rights pertaining to the registration of any common
stock to which the Investor Group may convert from Convertible Debt or
Preferred Stock, certain anti-dilution rights, and a right of first refusal on
any future offering of Company securities.

Under the terms of the transaction, the Company also issued a warrant to
purchase 100 shares of Series B Preferred Stock. The Series B Preferred Stock
entitled Amsterdam Equities Limited, 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 the 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 Convertible Debt
and Preferred Stock Agreements. Conversion pursuant to such conversion formula
would result in a conversion price per share of the Company's common stock
below present market levels.  If the Investor Group were to convert all
outstanding Convertible Debt and Preferred Stock at the present time, the
conversion would result in the issuance to the Investor Group of a majority
interest representing in excess of Fifty Percent (50.0%) of the issued and
outstanding shares of the Company's common stock (assuming full conversion and
anti-dilution).

In addition, pursuant to the terms of the Financing Arrangement, the Company
issued to the holders of the Convertible Debt and the Preferred Stock a series
of default warrants to purchase an aggregate of 4,125,000 shares of common
stock at an exercise price of $0.10 per share.  The Investor Group could
exercise the warrants only upon the occurrence of an event of default under the
terms of the Financing Arrangement or upon the failure by the Company to
achieve certain minimum financial goals of net income of at least one dollar in
the fiscal year ending December 31, 1996, and net income at least equal to 60%
of the dollar amount of Convertible Debt of the Company outstanding at the end
of 1997 for the fiscal year ending December 31, 1997, increased by 10% each
year thereafter, compounded, plus 60% of the additional Convertible debt
outstanding at the end of such year over the immediately preceding year. The
Company has been in ongoing default under the Financing Arrangement and the
stated financial goals have not been met, and, accordingly, these default
warrants have been capable of being exercised by the Investor Group upon
payment of the exercise price of $412,500 in the aggregate since January 1,
1997. The cumulative effect of the issuance of shares pursuant to the default
warrants to the Investor Group and the conversion of the outstanding
Convertible Debt/Preferred Stock could result in ownership by the Investor
Group of up to 75% of the Company's total issued and outstanding common stock.
To date, the Investor Group has taken no steps to exercise these default
warrants.

Pursuant to the Modification Agreement, and as an absolute pre-condition to the
waiver by the Investor Group of all accumulated and ongoing interest and/or
dividends on the Convertible Debt/Preferred Stock

                 Notes to the Consolidated Financial Statements
                                 June 30, 1997
                                  (Unaudited)


for the period from January 1, 1997 through December 31, 1997 (see Item 5 and
Exhibit 10.55), the Company agreed to reduce the exercise price of the default
warrants from $0.10 per share to $0.01 per share effective as of July 1, 1997.
This modification effectively reduces the aggregate exercise price of $412,000
for the default warrants to an aggregate exercise price of $41,200 (not
accounting for any adjustments due to changes in the total issued and
outstanding shares of the Company's common stock).

2. In August 1996, the Company entered into a Letter Agreement by and among the 
Company; Dr. Charles R. Mitchell, a former President of the Company; Stratum
Management, Inc., a former consultant to the Company; John H. Hagan, a former
director of the Company; Dr. Seymour Kessler, a former director of the Company;
and Amsterdam Equities Limited, Frank Leonard Laport, and Beverly Trust
Company, as Custodian of the Frank Leonard Laport Rollover Individual
Retirement Account No. 75-49990, each members of the Investor Group.  Under the
Letter Agreement, which became effective on August 9, 1996, the Series B
Preferred Stock previously referred to in the Convertible Debt Agreement
executed by the Company on April 22, 1996 was amended to be immediately
effective and Class B Preferred Stock was immediately 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 U.S. $700,000 of currently outstanding Convertible
Debt/Preferred Stock into the Company's Common Stock in accordance with the
contractual terms of the Convertible Debt and Preferred Stock Agreements
executed on April 22, 1996 and (ii) upon the advance to the Company of an
additional $200,000.00 pursuant to the Convertible Debt and the Preferred Stock
Agreements executed April 22, 1996.  As of August 9, 1996, the Investor Group
had satisfied these two conditions and the Class B Preferred Stock was issued
to Amsterdam. Frank Leonard Laport, Chairman and CEO of the Company, was 
elected as the Series B Director effective as of August 9, 1996. The Series B 
Director has not voted on any matters to date or taken any action whatsoever 
to date.

In connection with the activation of the Class B Preferred Stock, the provision
of additional funding and conversion of debt, Stratum, Hagan and Kessler agreed
to forfeit, on a pro rata basis, an aggregate amount of 300,000
options/warrants to purchase the Company's Common Stock of the Company.

ITEM 2  MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION
        AND RESULTS OF OPERATIONS

The following discussion should be read in conjunction with the attached
condensed consolidated financial statements and notes thereto, and with the
Company's audited financial statements and notes thereto for the year ended
December 31, 1996.

Results of Operations

Revenue for the six month period ended June 30, 1997 was $7,750,811 compared
with $9,427,504 for the six month period ended June 30, 1996, a decrease of
$1,676,693.  The change in revenue is due primarily to the sale of three dental
practices and one dental laboratory.  Operating expenses decreased $2,710,352
to $7,575,821 for the six month period ended June 30, 1997 from $10,286,173 for
the six month period ended June 30, 1996.  This decrease is due in large part
to the sales of the practices and dental laboratory, as well as several cost
cutting measures related to compensation, benefits, and various other practice
expenses.

                    PRINCETON DENTAL MANAGEMENT CORPORATION
                 Notes to the Consolidated Financial Statements
                                 June 30, 1997
                                  (Unaudited)



Interest expense increased $138,953 to $448,439 for the six month period ended
June 30, 1997 versus $309,486 incurred in the comparable three month period
last year.  The increase is primarily the result of interest accruing on the
Convertible Debt and Preferred Stock Agreements at the default rate.  As
indicated in Item 5, it is anticipated that the Modification Agreement and the
Allonge (see Exhibits 10.55 and 10.56) will have an ongoing material positive
effect upon the Company's interest expense.

The net loss decreased by $1,103,396 from $1,142,965 for the six month period
ended June 30, 1996, to $39,569 for the six month period ended June 30, 1997.
The net loss for the six month period ended June 30,1997 of $39,569 shows
substantial improvement over the prior year six month period ended June 30,
1996, primarily as a result of significant improvement in operations, the gain
from the sale of Century Dental Center, Mason Dental Southeast / Renaissance
Dental Studio, a reduction of the depreciation based on the sales of three
dental practices, and a dental laboratory, and a reduction of the monthly
amortization based on the write down of goodwill at December 31, 1996.  Losses
from operations are attributable to an increase in the overall cost of
providing dental services and expanding the patient base to include more
specialty services as well as the production cost within the laboratory
division.

Financial Condition

Changes in the Company's financial condition at June 30, 1997 as compared with
December 31, 1996 resulted primarily from a general improvement in operations
and the sale of three dental practices and a dental laboratory during the six
month period ended June 30, 1997.  During the six months ended June 30, 1997, 
the Company realized significant proceeds from the sale of Fairfield Dental, 
Center Century Dental Center, and Mason Dental Southeast / Renaissance
Dental Studio.  The sale of the Dental Team of Delray Beach was exclusively
forgiveness of debt.  The Company recognized no cash from the sale of the
Delray Beach practice.

During the first and second quarters of 1997, the Company arranged payment
terms with several of its suppliers.  Those suppliers have once again begun
extending standard credit terms, and orders are no longer shipped on a C.O.D.
basis.  One of the Company's largest suppliers has begun shipping supplies and
providing services based on a mutually agreed upon plan that has been put into
place to reduce the outstanding balances.

The Company is currently in the process of developing revenue enhancement
programs in both the dental practice segment as well as the laboratory segment.
In addition, the Company is also working to improve the operating results of
the various operations by reducing the costs of patient services including the
reduction in payroll.  The Company has begun steps to reduce general and
administrative expenses. However, the Company can make no assurances in regards
to the results of these programs.

In addition, the Company has sold its dental practices in Pennsylvania and its
dental laboratory in Florida.  These sales are consistent with the Company's
long-term business plans and should generally have a positive impact upon
operations.  No additional sales have been contemplated at this time.

During the first and second quarters of 1996, the Company did not deposit
certain state payroll tax liabilities totaling approximately $53,000.  The
Company filed the state payroll tax returns for the first and second quarters
of 1996 during the first quarter of 1997.  Management is currently negotiating
with the State to abate penalties associated with the late payment.  These
negotiations are under review by state authorities.

In addition, during 1994 the Company did not make certain federal payroll tax
deposits on a timely basis. The payroll deposits and all outstanding payroll
tax returns have been filed as of January, 1997.

                 Notes to the Consolidated Financial Statements
                                 June 30, 1997
                                  (Unaudited)


Management has provided a reserve of approximately $60,000 for the state tax
penalties and $70,000 to cover any IRS penalties.  Management believes these
reserves are sufficient to cover these obligations.


Liquidity and Capital Resources

As of June 30, 1997, the Company had a working capital deficit of $4,008,335
and a financial accumulated deficit of $13,770,302.  Goodwill and other
intangibles comprise approximately 62% of total assets, leaving tangible assets
of approximately $3,531,452 and negative tangible net worth of approximately
$4,713,830.

During the six month period ended June 30, 1997, the Company's cash and cash
equivalents increased $327,603.  Cash used in operations was $52,063, resulting
primarily from the Company's decrease in accounts receivable, which can be
attributed to the sale of the dental practices, accounts payable, and accrued
expenses.  These operations were partially offset by depreciation and
amortization of $363,325.

Investing activities provided $688,457 of cash, primarily related to the sale
of the dental practices and laboratory.  Cash of $308,791 was used in financing
activities, primarily as a result of the extinguishment of debt and principal
payments on capital lease obligations and notes payable in the amount of
$21,715.

As disclosed in Note 3, the Company's primary source of outside financing is
from the Investor Group.  Given the Company's working capital deficit and
negative tangible net worth, the Company is heavily reliant on the Investor
Group's financing to continue the Company's expansion plans and to a larger
extent, provide working capital to fund the operations.  As indicated in Item
5, the Company has reached agreement with the Investor Group as to a temporary
waiver of interest.

PART II - OTHER INFORMATION

Item 1.  Legal Proceedings

      a)   On October 16, 1996, the Company was sued for $160,000 by
           Romajo Partners Limited Partnership, a Partnership controlled by Dr.
           Seymour Kessler, a former director of the Company.  The Company
           intends to vigorously contest the suit and, in connection with this
           litigation, has brought various counterclaims against Dr. Kessler
           and has joined certain other individuals as parties to such
           litigation, including Dr. Charles Mitchell, a former officer and
           director of the Company.

      b)   The Company is involved in a number of other legal
           proceedings related to malpractice, worker's compensation, general
           employment and contract disputes all in various stages of
           proceedings, most of which will be covered by insurance.


Item 5.  Other Information

      1.   Effective as of August 4, 1997, the Board of Directors
           approved an extension of the expiration date of those warrants
           issued pursuant to that certain Warrant Agreement dated April 15,
           1992 between Princeton Dental Management Corporation and Continental
           Stock Transfer & Trust Company for a period of twelve (12) months,
           from October 13, 1997 through October 12, 1998.

      2.   Effective as of July 1, 1997, the Company entered into that
           certain Modification Agreement with the Investor Group.  Pursuant to
           the Modification Agreement, 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 (see Exhibit 10.55).  Assuming this
           waiver continues through December 31, 1997, this waiver on the part
           of the Investor Group will result in a total savings to the Company
           of in excess of $700,000.  Pursuant to the Modification Agreement,
           and as an absolute pre-condition to the waiver by the Investor Group
           of 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 (see Exhibit 10.55), the Company agreed to
           reduce the exercise price of the default warrants from $0.10 per
           share to $0.01 per share effective as of July 1, 1997.  This
           Modification effectively reduces the exercise price for the default
           warrants from an aggregate exercise price of $412,000 to an
           aggregate exercise price of $41,200 (not accounting for any
           adjustments due to changes in the total issued and outstanding
           shares of the Company's common stock).

      3.    Effective as of July 1, 1997, the Company, Mason Dental Midwest,
            Inc. and the constituent shareholders ("Constituent Shareholders")
            of the Delaware corporation formally known as Mason Dental, Inc.
            entered into that certain Allonge and Fourth Amendment to
            Acquisition Promissory Note ("Allonge").  Pursuant to the Allonge,
            the Constituent Shareholders agreed, conditioned upon continued
            listing by the Company on the Nasdaq SmallCap Market and similar
            concessions by the Investor Group (see Exhibit 10.55 and 10.56), to
            waive all ongoing interest that might be due pursuant to the
            Acquisition Promissory Note (as such term is defined in the
            Allonge) for the period from July 1, 1997 through June 30, 1998
            (see Exhibit 10.56).  Assuming this waiver continues

                 Notes to the Consolidated Financial Statements

                                  (Unaudited)


           through June 30, 1998, this waiver on the part of the Constituent
           Shareholders will result in a total savings to the Company of in
           excess of $120,000.

      4.   Previously, the Board of Directors of the Company had
           announced that, effective as of June 1, 1997, the Company had sold
           the assets comprising the Mason Dental Southeast, Inc. / Renaissance
           Dental Studio to Mr. Lawrence Ceraulo, individually and doing
           business as Certex Dental Studio.  The Mason Dental Southeast, Inc.
           / Renaissance Dental Studio, with 1996 revenues of approximately
           $390,000, represented approximately 2.2% of the total revenue of the
           Company, and has represented a loss in 1996 to the company.  The
           Mason Dental Southeast, Inc. / Renaissance Dental Studio was sold
           for $92,096 in the form of a short-term note; an additional
           short-term note payable to purchase supplies in the amount of
           $9,847; and an assumption of an existing note payable of $18,372.
           The sale of Mason Dental Southeast, Inc. / Renaissance Dental Studio
           was a profitable transaction for the Company, in the amount of
           approximately $49,000.
           
           Pursuant to the terms of the Company's agreement with Mr. Lawrence
           Ceraulo, individually and d/b/a Certex Dental Studio, Mr. Ceraulo
           was required to make payment in full of all amounts due and owing
           under the acquisition notes as of July 15, 1997.  Mr. Ceraulo has
           made payments of approximately $9,200, but approximately $100,000
           remains due and owing from Mr. Ceraulo.  The Company has agreed to
           extend the term of the acquisition notes through July, 1998, on
           terms advantageous to the Company (see Exhibit 10.57).
           
      5.   On November 6, 1996, NASDAQ approved, subject to public
           comment, certain modifications to the listing criteria on the NASDAQ
           System. These proposed modifications were extensive, and included a
           proposal that a company whose minimum bid price fell below $1.00 for
           a period of time could, in certain circumstances, be delisted. These
           proposed modifications are currently in the process of examination
           by the Securities and Exchange Commission for final approval. The
           Company's minimum bid price is currently below $1.00, and the
           Company can make absolutely no assurances regarding the final
           outcome of these proposed modifications to the listing criteria on
           the NASDAQ System or the impact which such modifications could have
           on the Company's continued listing on the NASDAQ System.  The
           Company has been advised that it is presently not in compliance with
           NASDAQ listing requirements, and, absent changes in Company
           operations, may, under certain circumstances, be delisted from the
           Nasdaq SmallCap Market.

     b.     Reports on Form 8-K

            The Registrant filed the following Form 8-Ks during the period from
            January 1, 1997 through June 30, 1997:

            1)    On January 16, 1997 the Registrant filed with
                  the Securities and Exchange Commission a current report on
                  Form 8-K regarding the sale of the assets of the Fairfield
                  Dental Center practice to Drs. Barfield and Payne. The
                  Fairfield practice, with 1995 revenues of approximately
                  $2,000,000, represented approximately 11.9% of the total
                  revenue of the Company. The Fairfield practice was sold for a
                  purchase price of approximately $885,000, of which
                  approximately $410,000 represented forgiveness of debt.

            2)    On February 11, 1997, the Registrant filed with
                  the Securities and Exchange Commission a current report on
                  Form 8-K regarding the sale of the assets of the Dental Team
                  of Delray Beach practice to Dr. Richard Staller. The Delray
                  Beach practice, with 1995 revenues of approximately $859,135,
                  represented approximately 5.1% of the total revenue of the
                  Company. The Delray Beach practice was sold for a purchase
                  price of approximately $200,000 in the form of forgiveness of
                  debt.

            3)    On May 23, 1997, the Registrant filed with the

                  8-K regarding the sale of the assets comprising the Century
                  Dental Center to Valley Forge Dental Associates, P.C.  The
                  Century Dental practice, with 1996 revenues of approximately
                  $965,000, represented approximately 5.3% of the total revenue
                  of PDMC.  The Century practice was sold for $585,000.  The
                  sales

             Renaissance Dental Studio to Mr. Lawrence Ceraulo, individually
             and doing business as Certex Dental Studio.  The Mason Dental
             Southeast, Inc. / Renaissance Dental Studio, with 1996 revenues of
             approximately $390,000, represented approximately 2.2% of the
             total revenue of PDMC, and has represented a loss in 1996 to the
             company.  The Mason Dental Southeast, Inc. / Renaissance Dental
             Studio was sold for $92,096 in the form of a short-term note; an
             additional short-term note payable to purchase supplies in the
             amount of $9,847; and an assumption of an existing note payable of
             $18,372. The sale of Mason Dental Southeast, Inc. / Renaissance
             Dental Studio was a profitable transaction for PDMC, in the amount
             of approximately $49,000.

                         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)

                        (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")

        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

                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
        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").





<PAGE>   5
                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 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





<PAGE>   6





        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 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 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,





<PAGE>   7





        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 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

        Assets; (iii) labor dispute or, to the best of the knowledge of the
        Seller, threatened labor dispute involving any of the employees of the

        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

<PAGE>   8





        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, 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.





<PAGE>   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
        the right, power and authority to sell and transfer the Assets owned by
        it to the Purchaser (or its designee), and upon such transfer the
        Purchaser (or its designee) will acquire good and marketable title to
        the Assets, free and clear of all liens, charges, encumbrances,
        security interests or claims whatsoever, except as set forth in Exhibit
        B.  The properties and assets of the Seller include all properties and
        assets used in the operations of the Business as currently conducted. 
        All such properties and assets of the Seller are in good condition and
        repair, consistent with their respective ages, and have been maintained
        and serviced in accordance with the normal practices of the Seller.
        None of such properties or assets is subject to any liens, charges,
        encumbrances or security interests, except as set forth in Exhibit B. 
        None of such properties or assets (including the Assets) (or uses to
        which they are put) fails to conform with any applicable agreement,
        law, ordinance or regulation in a manner which could reasonably be
        expected to have a Material Adverse Effect or is likely to be material
        to the operation of the Business.

                I. Taxes.  The Seller has filed or caused to be filed on a
        timely basis, all federal, state, local, foreign and other tax returns,
        reports and declarations (collectively, "Tax Returns") required to be
        filed by the Seller in connection with the Business except for those
        Tax Returns required to be filed for the taxable year ending December
        31, 1996 for which the Seller has timely filed an extension request. 
        All Tax Returns filed by the Seller on behalf of the Business are true,
        complete and correct in all material respects. The Seller has paid all
        income, estimated, excise, franchise, gross receipts, capital stock,
        profits, stamp, occupation, sales, use, transfer, value added, property
        (whether real, personal or mixed), employment, unemployment,
        disability, withholding, social security, workers' compensation and
        other taxes, and interest, penalties, fines, costs and assessments
        (collectively, "Taxes"), due and payable with respect to the periods
        covered by such Tax Returns (whether or not reflected thereon).  There
        are no tax liens on any of the properties or assets, real, personal or
        mixed, tangible or intangible, of the Seller in connection with the
        Business.  Since March 31, 1997, the Seller in connection with the
        Business has not incurred any tax liability other than in the ordinary
        course of business.  Except as set forth in Exhibit B, no Tax Return of
        the Seller in connection with the Business has ever been audited.  No
        deficiency in Taxes for any period has been asserted by any taxing
        authority which remains unpaid at the date hereof (the results of any
        settlement being set forth on Exhibit B hereto), no written inquiries
        or notices have been received by the Seller in connection with the
        Business from any taxing authority with respect to possible claims for
        Taxes and the Seller knows of no reason to believe that such an inquiry
        or notice is pending or threatened, and there is no basis for any
        additional claims or assessments for Taxes.  The Seller in connection
        with the Business has not agreed to the extension of the statute of
        limitations with respect to any Tax Return or tax period.  The Seller
        has delivered to the Purchaser copies of the federal and state income
        or





<PAGE>   10

        franchise or other type of Tax Returns filed by the Seller in
        connection with the Business for the past three years and for all other
        past periods as to which the appropriate statute of limitations has not
        lapsed.

                J. Permits; Compliance with Applicable Law.

                        (i) General.  The Seller is not in default under any, 
        and has complied with all, statutes, including the Americans with
        Disabilities Act, ordinances, regulations, orders, judgments and
        decrees of any court or governmental entity or agency, relating to the
        Business or the Assets as to which a default or failure to comply might
        have a Material Adverse Effect on the Business or the Assets.  The
        Seller has no knowledge of any basis for assertion of any violation of
        the foregoing or for any claim for compensation or damages or otherwise
        arising out of any violation of the foregoing.  The Seller has not
        received any notification of any asserted present or past failure to
        comply with any of the foregoing which has not been satisfactorily
        responded to in the time period required thereunder.

                        (ii) Permits.  Set forth in Exhibit B is a complete and
        accurate list of all permits, licenses, approvals, franchises and
        authorizations issued by governmental entities or other regulatory
        authorities, federal, state or local (collectively the "Permits"),
        held by the Seller in connection with the Business.  The Permits set
        forth in Exhibit B are all the Permits required for the conduct of the
        Business.  All the Permits set forth in Exhibit B are in full force and
        effect, and the Seller has not engaged in any activity which would
        cause or permit revocation or suspension of any such Permit, and no
        action or proceeding looking to or contemplating the revocation or
        suspension of any such Permit is pending or, to the best of the
        knowledge of the Seller, threatened.  There are no existing defaults or
        events of default or events or state of facts which with notice or
        lapse of time or both would constitute a material default by the Seller
        under any such Permit.  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 party in the performance of any obligation to be performed or
        paid by any party under any Permit set forth in Exhibit B.  Except as
        set forth in Exhibit B, the consummation of the transactions
        contemplated hereby will in no way affect the continuation, validity or
        effectiveness of the Permits set forth in Exhibit B or require the
        consent of any person.

                        (iii) Environmental.  (a) To the best of the knowledge
        of the Seller, the Seller in connection with the Business, has duly
        complied with, and the real estate owned by it or subject to the
        leases listed in Exhibit B and the improvements thereon, and all other
        real estate leased by the Seller in connection with the Business, and
        the improvements thereon (all such owned or leased real estate
        hereinafter referred to collectively as the "Premises") are in
        compliance with, the provisions of all federal, state and local
        environmental, health and safety laws, codes and ordinances and all
        rules and regulations promulgated thereunder, except where the failure
        to so comply would not have a Material Adverse Effect.

                                (b) To the best of the knowledge of the Seller,
        the Seller in connection with the Business has been issued, and will
        maintain until the date of the  Closing, all required federal, state
        and local permits, licenses, certificates and approvals relating to (i)
        air emissions, (ii) discharges to surface water or ground water,





<PAGE>   11





        (iii) noise emissions, (iv) solid or liquid waste disposal, (v) the
        use, generation, storage, transportation or disposal of toxic or
        hazardous substances or wastes (intended hereby and hereafter to
        include any and all such materials listed in any federal, state or
        local law, code or ordinance and all rules and regulations promulgated
        thereunder, as hazardous or potentially hazardous), or (vi) other
        environmental, health and safety matters.

                                (c) The Seller has not received any notice of,
        and knows of no facts which might constitute violations of, any
        federal, state or local environmental, health or safety laws, codes or
        ordinances, and any rules or regulations promulgated thereunder,
        which relate to the use, ownership or occupancy of any of the Premises
        owned, leased or occupied by the Seller in connection with the
        Business.  The Seller is not in violation of any rights-of-way or
        restrictions affecting any of the Premises or any rights appurtenant
        thereto.

                (iv)  Medicare, Medicaid and CHAMPUS.  The Business has
        had no net revenues from the Medicare, Medicaid and CHAMPUS programs 
        during the calendar years 1994, 1995, 1996, and the first four (4) 
        months of 1997.

                K. Licenses.  The Seller does not produce or distribute any 
        product nor does it perform any service under a proprietary license
        granted by another entity and it has not licensed its rights in
        any current or planned products, designs or services to any other
        entities.  The Seller has the right to use all computer software,
        including all property rights constituting part of that computer
        software, used in connection with the Business (the "Computer
        Software").  A list of all written licenses pertaining to the Computer
        Software is set forth in Exhibit B (the "Licenses").  The Seller does
        not have any knowledge that any of the Licenses may not be valid or
        enforceable by the Seller or that the use of the Computer Software or
        any of the Licenses may infringe upon or conflict with the rights of
        any third party.  The Seller has not granted any licenses to use the
        Computer Software or any sub-licenses with respect to any of the
        Licenses.

                L. Inventories.  The inventories and equipment of the Seller 
        in connection with the Business are in all material respects 
        merchantable and fully usable in the ordinary course of business.

                M. Contractual and Other Obligations.  Set forth in Exhibit B
        is a list and brief description of all (i) contracts, agreements,
        licenses, leases, arrangements (written or oral) and other documents to
        which the Seller in connection with the Business is a party or by which
        the Seller in connection with the Business is bound (including, in the
        case of loan agreements, a description of the amounts of any
        outstanding borrowings thereunder and the collateral, if any, for such
        borrowings); (ii) obligations and liabilities of the Seller in
        connection with the Business pursuant to uncompleted orders for the
        purchase of materials, supplies, equipment and services for the
        requirements of the Business with respect to which the remaining
        obligation of the Seller in connection with the Business is in excess
        of $7,500; and (iii) material contingent obligations and liabilities of
        the Seller in connection with the Business (all of the foregoing being
        hereinafter referred to as the "Contracts.")  The Seller is not in
        material default in the performance of any covenant or condition under
        any Contract and no claim of such a default has been made and, to the
        best of the knowledge of the Seller, no event has occurred which with
        the giving of notice or the lapse of time would





<PAGE>   12

        constitute a default under any covenant or condition under any
        Contract, except where such default would not have a Material Adverse
        Effect.  The Seller is not a party to any Contract which would
        terminate or be adversely affected by the consummation of the
        transactions contemplated by this Agreement.  The Seller in connection
        with the Business is not a party to any Contract expected to be
        performed at a loss.  Originals or true, correct and complete copies of
        all written Contracts have been provided to the Purchaser.

                N. Compensation.  Set forth in Exhibit D attached hereto is a
        list of all written or oral agreements between the Business and each
        person employed by or independently contracting with the Business with
        regard to compensation, whether individually or collectively, and set
        forth in Exhibit D is a list of all employees or independent
        contractors of the Business entitled to receive annual compensation in
        excess of $35,000 and their respective positions, job categories and
        salaries.  The transactions contemplated by this Agreement will not
        result in any liability for severance pay to any employee or
        independent contractor of the Business.  The Business has not informed
        any employee or independent contractor providing services to the
        Business that such person will receive any increase in compensation or
        benefits or any ownership interest in the Business.

                O. Employee Benefit Plans.  Except as set forth in Exhibit E
        attached hereto, neither the Seller nor its parent corporation (the
        "Parent") maintains or sponsors, nor are they required to make
        contributions to, any pension, profit-sharing, savings, bonus,
        incentive or deferred compensation, severance pay, medical, life
        insurance, welfare or other employee benefit plan.  All pension,
        profit-sharing, savings, bonus, incentive or deferred compensation,
        severance pay, medical, life insurance, welfare or other employee
        benefit plans within the meaning of Section 3(3) of the Employee
        Retirement Income Security Act of 1974, as amended (hereinafter
        referred to as "ERISA"), in which the employees of the Business
        participate (such plans and related trusts, insurance and annuity
        contracts, funding media and related agreements and arrangements being
        hereinafter referred to as the "Benefit Plans") comply with all
        requirements of the Department of Labor (the "DOL") and the Internal
        Revenue Service, and with all other applicable law, and neither the
        Seller nor the Parent has taken or failed to take any action with
        respect to the Benefit Plans which might create any liability on the
        part of the Seller or the Purchaser. Each "fiduciary" (within the
        meaning of Section 3(21)(A) of ERISA) as to each Benefit Plan has
        complied in all respects with the requirements of ERISA and all other
        applicable laws in respect of each such Benefit Plan.  The Seller has
        furnished to the Purchaser copies or accurate summaries of all Benefit
        Plans and all financial statements, actuarial reports and annual
        reports and returns filed with the Internal Revenue Service with
        respect to such Benefit Plans for a period of three years prior to the
        date hereof.  Such financial statements, actuarial reports and annual
        reports and returns are true and correct in all respects, and none of
        the actuarial assumptions underlying such documents have changed since
        the respective dates thereof.  In addition:

                        (i) Each Benefit Plan intended to qualify under Section
                401(a) of the Code has received a favorable determination 
                letter from the Internal Revenue Service as to its 
                qualification under Section 401(a) of the Code;






<PAGE>   13

                        (ii) Neither the Seller nor the Parent maintains, 
                sponsors or contributes to (nor are required to contribute to)
                and has never withdrawn from, maintained, sponsored or
                contributed to (nor has ever been required to contribute to)
                a "defined benefit plan" (within the meaning of Section 3(35)
                of ERISA), or a "multiemployer plan" (within the meaning of
                Section 3(37) of ERISA);

                        (iii) Neither the execution and delivery of this 
                Agreement nor the consummation of the transactions contemplated
                herein will result in the withdrawal (partially or totally
                within the meaning of ERISA) from any Benefit Plan, or in any
                withdrawal or other liability of any nature to the Seller, the
                Parent or the Purchaser under any Benefit Plan;

                        (iv) No "prohibited transaction" (within the meaning of
                Section 406 of ERISA or Section 4975(c) of the Code) has
                occurred with respect to any Benefit Plan;

                        (v) No provision of any Benefit Plan or of any
                agreement, and no act or omission of the Seller or the Parent
                in any way limits, impairs, modifies or otherwise affects the
                right of the Seller or the Parent to amend any Benefit Plan,
                subject to the requirements of applicable law;

                        (vi) There are no contributions which are or hereafter
                will be required to have been made to trusts on behalf of the
                employees of the Business in connection with any Benefit Plan
                that would constitute a "defined contribution plan" (within the
                meaning of Section 3(34) of ERISA);

                        (vii) Other than claims in the ordinary course for
                benefits with respect to the Benefit Plans, there are no
                actions, suits or claims (including claims for income Taxes,
                interest, penalties, fines or excise Taxes with respect
                thereto) pending with respect to any Benefit Plan, or any
                circumstances which might give rise to any such action, suit or
                claim (including claims for income Taxes, interest, penalties,
                fines or excise Taxes with respect thereto);

                        (viii) All reports, returns and similar documents with
                respect to the Benefit Plans required to be filed with any
                governmental agency have been so filed; and

                        (ix) Neither the Seller nor the Parent has any
                obligation to provide health or other welfare benefits to
                former, retired or terminated employees, except as specifically
                required under Section 4980B of the Code or Section 601 of
                ERISA.  The Seller and the Parent has complied with the notice
                and continuation requirements of Section 4980B of the Code and

                        The Seller agrees that it will or cause the Parent to,

        federal, state or local statutes, laws, ordinances, rules, regulations,
        orders or directives with respect to the employment of individuals by,
        or the employment practices or work conditions of the Business, or with
        respect to the terms and conditions of employment, wages and hours,
        which violations would have, either individually or in the aggregate, a
        Material Adverse Effect.  The Business is not engaged in any unfair
        labor practice or other unlawful employment practice and there are no
        charges of unfair labor practices or other employee-related complaints
        pending or, to the best of the knowledge of the Seller, threatened
        against the Business or before the National Labor Relations Board, the
        Equal Employment Opportunity Commission, the Occupational Safety and
        Health Review Commission, the Department of Labor or any other federal,
        state, local or other governmental authority.  There is no strike,
        picketing, slowdown or work stoppage or organizational attempt pending
        or, to the best of the knowledge of the Seller, threatened against or
        involving the Business.  No issue with respect to union representation
        is pending or, to the best of the knowledge of the Seller, threatened
        with respect to the employees of the Business.  No union or collective
        bargaining unit or other labor organization has ever been certified or
        recognized by Business as the representative of any of the employees of
        the Business.

                Q. Increases in Compensation or Benefits.  Except as set forth
        in Exhibit D, subsequent to March 31, 1997, there have been no
        increases in the compensation payable or to become payable to any of
        the employees involved in the Business and there have been no payments  
        or provisions for any awards, bonuses, stock options, loans, profit
        sharing, pension, retirement or welfare plans or similar or other
        disbursements or arrangements for or on behalf of such employees (or
        related parties thereof), in each case, other than pursuant to
        currently existing plans or arrangements, if any, set forth in Exhibit
        E; provided, however, that in no event was any such increase in
        compensation or any such payment or provision made with respect to any
        employees earning in excess of $20,000 per annum.  All commissions
        heretofore earned and all bonuses heretofore granted to employees
        involved in the Business have been paid in full to such employees.  The
        vacation policy of the Business is set forth in Exhibit E.  Except as
        set forth in Exhibit D, no employee involved in the Business is
        entitled to vacation time in excess of three weeks during the current
        calendar year and no employee involved in the Business has any accrued
        vacation or sick time with respect to any prior period. 

                R. Insurance.  The Seller maintains insurance policies covering
        all of its assets and properties and the various occurrences which may
        arise in connection with the operation of the Business.  Such policies
        are in full force and effect and all premiums due thereon prior to or
        on the date of the Closing have been paid in full.  The Seller has
        complied in all respects with all the provisions of such policies.  A
        complete list of the insurance policies maintained by the Seller with
        regard to the Business is set forth in Exhibit B.  There are no notices
        of any pending or, to the best of the knowledge of the Seller,
        threatened termination or premium increases with respect to any of such
        policies.  The Seller has not had any material casualty loss or
        occurrence which may give rise to any claim of any kind not covered by
        insurance and the Seller is not aware of any occurrence which may give
        rise to any claim of any kind not covered by insurance.  To the best of
        the knowledge of the Seller, no third party has filed any claim against
        the Seller for personal injury or property damage of a kind for which
        liability insurance is generally available which is not fully insured,
        subject only to the standard





<PAGE>   15
        deductible.  All claims against or involving the Business covered by 
        insurance have been reported to the insurance carrier on a timely basis.

                S. Conduct of Business.  The Seller is not restricted from
        conducting the Business in any location by agreement or court decree.

                T. Allowances.  The Seller has no obligation to make allowances
        to any of its customers or patients, except allowances which are
        consistent with its past practices.

                U. Patents, Trademarks, etc.  Set forth in Exhibit F attached
        hereto is a list and brief description of all of the patents,
        registered and common law trademarks, service marks, tradenames,
        copyrights, licenses and other similar rights of the Seller in
        connection with the Business and applications for each of the
        foregoing.  The Seller owns all right, title and interest in and to all
        such proprietary rights.  To the best of the knowledge of the Seller,
        the proprietary rights listed are all such rights necessary to the
        conduct of the Business as currently conducted by the Seller; no
        adverse claims have been made and no dispute has arisen with respect to
        any of the said proprietary rights; and the operations of the Business
        and the use by the Seller of such proprietary rights do not involve
        infringement or claimed infringement of any patent, trademark, service
        mark, tradename, copyright, license or similar right.

                V. Power of Attorney.  The Seller in connection with the
        Business has not granted any power of attorney (revocable or
        irrevocable) to any person, firm or corporation for any purpose
        whatsoever.

                W. Use of Names.  All names under which the Business is
        currently conducted are listed in Exhibit F.  Except for Century Dental
        Center I, P.C. and Century Dental Center II, P.C., there are no other
        persons or businesses conducting businesses similar to those of the
        Seller in the Commonwealth of Pennsylvania having the right to use or
        using any of the names set forth in Exhibit F or any variants of such
        names; and no other person or business has ever attempted to restrain
        the Seller from using such names or any variants thereof.

                X. Accounts Payable, Indebtedness, Etc.  The accounts and notes
        payable and accrued expenses reflected in the Financial Statements, and
        the accounts and notes payable and accrued expenses incurred by the
        Seller in connection with the Business subsequent to the date of the
        Financial Statements, are in all respects valid claims that arose in
        the ordinary course of business.  Since March 31, 1997, the accounts
        and notes payable, accrued expenses and debt of the Seller in
        connection with the Business have been paid in a  manner consistent
        with past practice.

                Y. No Foreign Person.  The Seller is not a foreign person 
        within the meaning of Section 1445(b)(2) of the Code.

                Z. Licensure, etc.  Each individual employed or contracted with
        by the Seller in connection with the Business to provide professional
        services is licensed to provide such services and is otherwise in
        compliance with all federal, state and local laws, rules and
        regulations relating to such professional licensure.  Each individual
        now or formerly employed or contracted with by the Seller in connection
        with the Business to





<PAGE>   16

        provide professional services was duly licensed to provide such
        services during all periods prior to the Closing when such employee or
        independent contractor provided such services on behalf of the Seller. 
        The Seller in connection with the Business is in compliance with all
        relevant state laws and precedents relating to the corporate practice
        of the learned or licensed professions, and there are no material
        claims, disputes, actions, suits, proceedings or investigations
        currently pending, or, to the best of the knowledge of the Seller,
        threatened or filed or commenced against or affecting the Business or
        any such licensed professional providing services to the Seller on the
        date of the Closing relating to such laws and precedents, and no such
        material claim, dispute, action, suit, proceeding or investigation has
        been filed or commenced during the five-year period preceding the date
        of this Agreement, and the Seller is not aware of any basis for such a
        valid claim.  To the best of the knowledge of the Seller, the
        acquisition of the Assets by the Purchaser (or its designee) as
        contemplated by this Agreement will not affect the ability of the
        Purchaser to operate the Business as heretofore operated in compliance
        with all applicable laws provided that the Purchaser complies with all
        applicable laws regarding the corporate practice of dentistry.

                AA. Books and Records.  The books and records of the Business
        are in all material respects complete and correct, have been maintained
        in accordance with good business practices and accurately reflect the
        basis for the financial position and results of operations of the
        Business set forth in the Financial Statements.  All of such books and
        records, including true and complete copies of all material written
        Contracts, have been made available for inspection by the Purchaser and
        its representatives.

                BB. Litigation; Disputes.  Except as set forth in Exhibit B,
        there are no claims, disputes, actions, suits, investigations or
        proceedings pending or, to the best of the knowledge of the Seller,
        threatened against or affecting the Business or the Assets.  Except as
        set forth in Exhibit B, no such claim, dispute, action, suit,
        proceeding or investigation has been pending or, to the best of the
        knowledge of the Seller, threatened during the five-year period
        preceding the date of this Agreement.  There is no basis for any such
        claim, dispute, action, suit, investigation or proceeding.  The Seller
        has no knowledge of any default under any such action, suit or
        proceeding.  The Seller in the conduct of the Business is not in
        default in respect of any judgment, order, writ, injunction or decree
        of any court or of any federal, state, municipal or other government
        department, commission, bureau, agency or instrumentality or any
        arbitrator.

                CC. Location of Seller and Assets.  Set forth in Exhibit B is
        each location (specifying state, county and city) where the Seller in
        connection with the Business, (i) has a place of business, (ii) owns or
        leases real property and (iii) owns or leases any other property,
        including inventory, equipment and furniture.

                DD. Bank Accounts.  Set forth in Exhibit G attached
                    hereto is a list of all bank accounts maintained in the
                    name of the Seller in connection with the Business, and a
                    brief description of the persons having power to sign
                    with respect to each such account.

                EE. Disclosure.  No representation or warranty made
                    under any Section hereof and none of the information
                    furnished by the Seller set forth herein, in the exhibits
                    hereto or in any document





<PAGE>   17
                    delivered by the Seller to the Purchaser, or any authorized
                    representative of the Purchaser, pursuant to this Agreement
                    contains any untrue statement of a material fact or omits
                    to state a material fact necessary to make the statements
                    herein or therein not misleading.

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


                A. Organization and Qualification.  The Purchaser is duly
        organized, validly existing and in good standing under the laws of the
        State of Delaware and has full corporate power and authority to
        purchase the Assets.

                B. Authority.  The execution and delivery of this Agreement by
        the Purchaser, the performance by the Purchaser of its covenants and
        agreements hereunder and the consummation by the Purchaser 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 Purchaser, enforceable against it in
        accordance with its terms.

                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 Purchaser 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 Purchaser is a party or by which the
        Purchaser or any of its assets is bound.

                                   SECTION IV

                          ADDITIONAL COVENANTS OF THE
                            SELLER AND THE PURCHASER

                A. Correspondence, Etc.  The Seller covenants and agrees that,
        subsequent to the Closing, it will deliver to the Purchaser, promptly
        after the receipt thereof, all inquiries, correspondence and other
        materials received by it from any person or entity relating to the
        Business.

                B. Books and Records.  Each of the Purchaser and the Seller
        covenants and agrees that, subsequent to the Closing, it shall give the
        other party reasonable access to the historical financial books and
        records and patient files of the Business (subject to applicable laws
        regarding confidentiality of such patient files), to the extent such
        books and records and files are not included in the Assets, for a
        period of five years from the date of the Closing.  Each of the
        Purchaser and the Seller shall retain all such books and records and
        files in substantially their condition at the time of





<PAGE>   18

        the Closing.  None of such books and records and files shall be
        destroyed without the prior written approval of the other party
        or without first offering such books and records and files to the other
        party.

                C. Discharge of Obligations.  The Seller covenants and agrees,
        subsequent to the Closing, to pay promptly and to otherwise fulfill and
        discharge all obligations and liabilities of the Seller in connection
        with the Business which are not Assumed Liabilities hereunder when due
        and payable and otherwise prior to the time at which any of such
        obligations or liabilities could in any way result in or give rise to a
        claim against the Assets, the Business or the Purchaser, result in the
        imposition of any lien, charge or encumbrance on any of the Assets, or
        adversely affect the Purchaser's title to or use of any of the Assets
        including, without limitation, any and all sales, use, transfer,
        corporate, payroll and/or business and mercantile taxes, penalties and
        interest owned to the Commonwealth of Pennsylvania and/or Marple
        Township, and processing fees required by that certain Real Property
        Lease (the "Lease") listed under "Real Property" in Exhibit B hereto
        for the facility located at 400 South State Road, Springfield,
        Pennsylvania, (the "Facility") in connection with the Assignment of
        Lease to be entered into between the Purchaser and the Seller on the
        date of the Closing for the Facility (the "Assignment of Lease").

                D. Delivery of Funds.  Subsequent to the Closing, the Seller
        shall deliver on a daily basis any funds and any checks except for
        those checks which relate to pre-closing receivables (as hereinafter
        defined), notes, drafts and other instruments for the payment of money,
        duly endorsed to the Purchaser, received by the Seller comprising
        payment of any amounts due from customers of the Business or others for
        services rendered by the Business, including pursuant to any provider
        agreements constituting part of the Assets.

                E. Collection of Accounts Receivable.  The Purchaser covenants
        and agrees to act as collection agent on behalf of the Seller with
        respect to the accounts receivable of the Business which were
        outstanding on the date of the Closing (the "pre-closing receivables")
        and the Purchaser further covenants and agrees to use its reasonable
        best efforts to collect such pre-closing receivables for a reasonable
        period of time not to exceed one (1) year from the date hereof or such
        shorter time upon the mutual agreement of the Seller and the Purchaser.

                The Seller covenants and agrees to pay to the Purchaser a fee
        equal to ten percent (10%) of the pre-closing receivables collected by
        the Purchaser to compensate the Purchaser for the services rendered
        with respect to the collection of the pre-closing receivables by the
        Purchaser.

                F. Post-Closing Third Party Consents.  In the event that any
        third party consents which the Seller is required to obtain (including
        consent to the Assignment of Lease) are not obtained prior to Closing
        and the Closing nonetheless occurs, the Seller hereby covenants to use
        such party's best efforts to obtain such consents within 30 days
        following the Closing.

                G. Pass Through of Rights and Obligations.  In the event that
        the Seller is unable to obtain the necessary consents set forth in
        Exhibit B hereto prior to the Closing and the Closing nevertheless
        occurs, the Seller agrees that until such time





<PAGE>   19

        as such consents are obtained or in the event the Seller is unable to
        obtain such consents, the Seller shall pass through to the Purchaser
        the benefits and the obligations arising under the agreements
        listed under "Real Property", "Contracts" and "Provider Source
        Contracts" in Exhibit B hereto as if such agreements were assigned to
        the Purchaser (or its designee) pursuant to this Agreement.  The
        Purchaser agrees that such pass through of rights and obligations shall
        satisfy all obligations of the Seller to obtain the necessary consents
        set forth in Exhibit B.

                H. Assignment of Lease.  The Purchaser covenants and agrees
        that within ten (10) business days of receiving written notice from
        Marple XYZ Associates (the "Landlord") that the Landlord consents to
        the Assignment of Lease, the Purchaser shall pay to the Seller (i)
        $7,542 in immediately available funds, which amount shall represent the
        security deposit under the Lease, less fifteen percent (15%), and (ii)
        the Purchaser's pro rata share (from the date of the Closing) of the
        rental payment under the Lease for the month of May, 1997.  In the
        event that the Landlord's consent is not granted on or before May 31,
        1997, the Purchaser may elect to pay to the Seller the rental payment
        for the month of June, and, in such event, the Seller covenants and
        agrees to timely pay to the Landlord the monthly rental payment for the
        month of June.  In the event that the Landlord does not consent to the
        Assignment of Lease, each of the Purchaser and the Seller covenants and
        agrees that the Purchaser (or its designee) and the Seller shall enter
        into a sublease for the Facility.

                                   SECTION V

        upon by the parties.

                B. Delivery of Assets.  Delivery of the Assets shall be made by
        the Seller to the Purchaser (or its designee) at the Closing by
        delivering such deeds, bills of sale, assignments and other instruments
        of conveyance and transfer, and such powers of attorney, as shall be
        effective to vest in the Purchaser (or its designee) title to or other
        interest in, and the right to full custody and control of, the Assets,
        free and clear of all liens, charges, encumbrances and security
        interests whatsoever.

                C. Tax Matters.  All transfer, documentary, stamp,
        registration, value added, sales, use and other such taxes and fees
        (including any penalties and interest) incurred in connection with this
        Agreement shall be borne and paid by the Seller when due, and the
        Seller will, at its own expense, file all necessary tax returns and
        other documentation with respect to all such taxes and fees.

                D. Assumption of Liabilities.  At the Closing, the Purchaser

                                  SECTION VII

               CONDITIONS TO THE PURCHASER'S OBLIGATION TO CLOSE

                The obligation of the Purchaser to purchase the Assets and
        otherwise consummate the transactions contemplated by this Agreement at
        the Closing is subject to the following conditions precedent, any or
        all of which may be waived by the Purchaser in its sole discretion, and
        each of which the Seller hereby agree to use its best efforts to
        satisfy at or prior to the Closing:

                A. Opinion of Counsel.  The Purchaser shall have received an
        opinion of Brooks & Cahill, Attorneys at Law, counsel for the Seller,
        delivered to the Purchaser pursuant to the instructions of the Seller,
        dated the date of the Closing, in form and substance satisfactory to
        the Purchaser and its counsel, Messrs. Haythe & Curley, to the effect
        that:

                        (i) The Seller is a corporation duly organized, validly
                existing and in good standing under the laws of the State of
                Florida, and is duly qualified to do business in the
                Commonwealth of Pennsylvania.  The Seller has full corporate
                power and authority to own its properties and to conduct the
                businesses in which it is now engaged.

                        (ii) This Agreement has been duly authorized, executed
                and delivered by the Seller and constitutes the 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.

                        (iii) Neither the execution and delivery of this
                Agreement, nor the consummation of the transactions
                contemplated hereby, violates any provision of the articles of
                incorporation or by-laws of the Seller.  To the knowledge of
                such counsel, based solely upon a representation from the
                Seller, neither the execution and delivery of this Agreement,
                nor the consummation of the transactions contemplated thereby,
                violates any statute, ordinance, regulation, order, judgment or
                decree of any court or governmental agency 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
                (related to the Business) to which the Seller is a party or by
                which the Seller or the Assets (as such term is defined in the
                Agreement) is bound.

                        (iv) The deeds, bills of sale, assignments and other
                instruments of transfer of ownership delivered by the Seller
                have been duly executed and delivered and are valid and binding
                in accordance with their terms.  To the knowledge of such
                counsel, based solely upon a representation of the Seller, the
                deeds, bills of sale, assignments and other instruments of
                transfer of ownership delivered by the Seller are sufficient to
                convey to the Purchaser (or





<PAGE>   22

                its designee) all the right, title and interest of the Seller
                in and to the Assets, free and clear of any liens, charges, 
                security interest or claims whatsoever except for those liens 
                set forth in Exhibit B.

                        (v) To the knowledge of such counsel, based solely upon
                representation of the Seller there are no claims, disputes,
                actions, suits or proceedings pending or threatened against the
                Seller with regard to the Business or the Assets.

                B. No Litigation.  No action, suit or proceeding against the
        Seller or the Purchaser relating to the consummation of any of the
        transactions contemplated by this Agreement nor any governmental action
        seeking to delay or enjoin any such transactions shall be pending or
        threatened.

                C. Representations and Warranties.  The representations and
        warranties made by the Seller herein shall be correct as of the date of
        the Closing in all respects with the same force and effect as though
        such representations and warranties had been made as of the date of the
        Closing, and on the date of the Closing, the Seller shall deliver to
        the Purchaser a certificate dated the date of the Closing to such
        effect.  All the terms, covenants and conditions of this Agreement to
        be complied with and performed by the Seller on or before the date of
        the Closing shall have been duly complied with and performed in all
        respects, and on the date of the Closing, the Seller shall deliver to
        the Purchaser a certificate dated the date of the Closing to such
        effect.

                D. Other Certificates.  The Purchaser shall have received such
        other certificates, instruments and other documents, in form and
        substance satisfactory to the Purchaser and counsel for the Purchaser,
        as it shall have reasonably requested in connection with the
        transactions contemplated hereby.

                E. Sale of All the Assets.  All of the Assets of the Business,
        with the exception of the Excluded Assets, shall be sold to the
        Purchaser (or its designee) at the Closing.

                F. Third Party Consents.  The Purchaser shall have received all
        necessary consents of third parties under the contracts, agreements,
        leases and other instruments of the Business, which consents shall not
        provide for the acceleration of any liabilities or any other detriment
        to the Purchaser or the Business.

                G. Malpractice Insurance.  The Seller shall present evidence
        satisfactory to the Purchaser that each professional employed by the
        Business shall have malpractice insurance in such amounts as are
        necessary and customary for such professionals.

                H. Employment Agreement and Modification Agreement.  The
        Purchaser (or its designee) and Nash shall have entered into the
        Employment Agreement and Modification Agreement.

                I. Governmental Licenses and Permits.  The Purchaser (and its
        designee) have obtained all required authorizations, permits and
        licenses required for it to operate the Business.





<PAGE>   23

                J. Assignment of Lease.  The Purchaser (or its designee) and
        the Seller shall have entered into the Assignment of Lease.

                                  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 Marple 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 Haythe
        & Curley 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.

                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





<PAGE>   24

        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 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.






<PAGE>   25

                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.

                                   SECTION IX

                              BROKERS AND FINDERS

                A. The Seller's Obligations.  The Purchaser shall not have any
        obligation to pay any fee or other compensation to any person, firm or
        corporation dealt with by the Seller in connection with this Agreement
        and the transactions contemplated hereby and the Seller hereby agrees
        to indemnify and save the Purchaser (or its designee) harmless from any
        liability, damage, cost or expense arising from any claim for any such
        fee or other compensation.






<PAGE>   26

                B. The Purchaser's Obligations.  The Seller shall not have any
        obligation to pay any fee or other compensation to any person, firm or
        corporation dealt with by the Purchaser in connection with this
        Agreement and the transactions contemplated hereby and the Purchaser
        agrees to indemnify and save the Seller harmless from any liability,
        damage, cost or expense arising from any claim for any such fee or
        other compensation. 

                                  SECTION X

                              TRANSFER OF NAME

                At the Closing, the Seller shall deliver to the Purchaser a
        written consent duly executed by the Seller evidencing its consent to
        the use by the Purchaser and any subsidiaries, affiliated companies or
        assigns of the Purchaser of the name "Century Dental" and all variants
        thereof.

                                 SECTION XI

        take promptly all necessary steps (as set forth in such notice) to
        carry out such restructuring.  The expenses related to such
        restructuring shall be borne by the Purchaser.

                H. Invalidity.  Should any provision of this Agreement be held
        by a court or arbitration panel of competent jurisdiction to be
        enforceable only if modified, such holding shall not affect the
        validity of the remainder of this 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 originally
        set forth in this Agreement.  The parties further agree that any such
        court or arbitration panel is expressly authorized to modify any such
        unenforceable provision of this Agreement in lieu of severing such
        unenforceable provision from this Agreement in its entirety, whether by
        rewriting the offending provision, deleting any or all of the offending
        provision, adding additional language to this Agreement, or by making
        such other modifications as it deems warranted to carry out the intent
        and agreement of the parties as embodied herein to the maximum extent
        permitted by law.  The parties expressly agree that this Agreement as
        modified by such court or arbitration panel shall be binding upon and
        enforceable against each of them. In any event, should one or more of
        the provisions of this Agreement be held to be invalid, illegal or
        unenforceable in any respect, such invalidity, illegality or
        unenforceability shall not affect any other provisions hereof, and if
        such provision or provisions are not modified as provided above, this
        Agreement shall be construed as if such invalid, illegal or
        unenforceable provisions had never been set forth herein.

                I. Successors and Assigns.  This Agreement shall be binding
        upon and inure to the benefit of the successors and assigns of the
        Seller and the Purchaser, respectively.

                J. Governing Law.  The validity of this Agreement and of any of
        its terms or provisions, as well as the rights and duties of the
        parties under this Agreement, shall be construed pursuant to and in
        accordance with the laws of the Commonwealth of Pennsylvania.

                K. Counterparts.  This Agreement may be executed in
        counterparts, each of which shall be deemed an original, but all of
        which taken together shall constitute one and the same instrument.

                              CONTINGENT PAYMENTS

                The Target 100% net operating revenues and Contingent Payments
are as follows:

        (1)     Contingent Period Ending May 31, 1997:

                Target 100% net operating
                      revenues                                  $500,000

                Target 100% Contingent Payments  $90,000

        (2)     Contingent Period Ending May 31, 1998:

                Target 100% net operating
                      revenues                                  $550,000

                Target 100% Contingent Payments  $50,000


                The aggregate amount of the Contingent Payments payable
to the Seller shall be determined by multiplying the Target 100%        
Contingent Payments for the applicable Contingent Period by the Contingent
Multiplier (as hereinafter defined) for such Contingent Period.

                The "Contingent Multiplier" shall be equal to the lesser of (i)
100%, and (ii) a fraction, expressed as a percentage, the numerator of which
shall be the net operating revenues of the Company for the applicable
Contingent Period calculated in accordance with Sections I(D) and (E) and the
denominator of which shall be the "Target 100% net operating revenues" set
forth above for such Contingent Period.

                Notwithstanding anything else in this Agreement to the contrary,
the Purchaser shall have no obligation to make the Contingent Payments provided
for in Section I(D) with respect to any Contingent Period if the net operating
revenues of the Company are less than 90% of the Contingent Target 100% 
therefor for any such Contingent Period.  The maximum Contingent Payments for 
any Contingent Period shall be 100% of the Target 100% Contingent Payments for
such Contingent Period.

however, that at the sole option of Mason Southeast, Mason Southeast may
elect to allow Certex to pay the full amount of the purchase price in the form
of a Forty-Five (45) day secured note in form and substance acceptable to Mason
Southeast. The purchase price with respect to Renaissance would be the
assumption of the Promissory Note included within the Renaissance Agreements.

        5. Accounts Receivable.  Mason Southeast and Renaissance accounts
receivable for work/services rendered in the ordinary course of business prior
to the date of closing would be the property of, and would accrue to the
benefit of, Mason Southeast. Mason Southeast and Renaissance accounts

of, Certex.

        6. Work in Progress. Mason Southeast and Renaissance work in progress
created in the ordinary course of business prior to the date of closing would
be the property of, and would accrue to the benefit of, Mason Southeast.

        7. Liabilities. Mason Southeast and Renaissance accounts payable 
incurred in the ordinary course of business prior to the date of closing would
be the responsibility of Mason Southeast. Any and all liabilities incurred
post-closing in connection with the ongoing operation of Mason Southeast and
Renaissance including, without limitation, the employment and payment of
benefits (including, without limitation, any accrued vacation time) to the
individuals listed on Exhibit A attached hereto and incorporated herein
(collectively, the "Mason Southeast and Renaissance Employees"), shall be
solely Certex's responsibility.





<PAGE>   3
        8. Ongoing Contractual Relationship. Certex agrees that, for a period of
three (3) years from the closing date, it shall, at the sole option of the
Florida Dental Team, P.A., continue to provide dental laboratory services as
may be required to members of The Florida Dental Team, P.A. at the same price
and on the same terms as are presently provided by Mason Southeast and/or
Renaissance to The Florida Dental Team, P.A. The parties acknowledge that it is
essential that Certex be able to meet all volume and quality requirements of
The Florida Dental Team, P.A., and Certex represents and warrants that Certex
will be able to meet or exceed such requirements. The parties further
acknowledge that this agreement was an essential inducement for Mason Southeast
to enter into this agreement with Certex, and the parties agree that Mason
Southeast, and/or The Florida Dental Team, P.A., shall be entitled to
injunctive relief, in addition to any suit for damages, in the event that
Certex violates this agreement.

        9. Certain Taxes.  Mason Southeast would pay current as of the date of
closing, all state and federal payroll taxes relating to Mason Southeast and

Security on the Mason Southeast and Renaissance Employees.

        In addition, both parties acknowledge that it may be necessary for a

compensation insurance (if any) relating to the Mason Southeast and Renaissance
Employees.

        11. Building Leases.  All amounts due under the building leases 
currently in existence for Mason Southeast and Renaissance would be paid 
current through the date of closing. The parties acknowledge that, at present,
no amounts are  due from Mason Southeast in this regard other than currently
pending monthly lease payments. Post closing, all responsibilities under such
leases would be the sole responsibility of Certex. The parties agree to use
their very best efforts to obtain the consent of the landlord for the
assignment and assumption of that certain Lease Agreement dated February 26,
1993 regarding the Pompano Square Dental Lab location; provided, however, that,
in the event that such consent is delayed or otherwise not obtained, the
parties shall enter into a pass-through arrangement whereby Certex shall be
solely responsible for any and all obligations pursuant to such Lease
Agreement.

        12. Record Keeping. Certex would agree to maintain in the ordinary 
course of business all prior business records of Mason Southeast and 
Renaissance and to provide reasonable access to such records to Mason Southeast

the Board of Directors of Mason Southeast and Mason Midwest, but otherwise
constitutes a legally binding obligation on the parties hereto without the need
for any additional documentation; provided, however, that the parties mutually
agree to enter into any other documentation which may be deemed reasonably
necessary by counsel solely in order to properly effectuate the transactions
contemplated herein.  All parties shall bear their own costs in this regard,
including those of legal counsel.

        If these terms are acceptable to you, please indicate your acceptance by
initialling each page, signing this letter below and returning it to us via
telecopy and overnight mail. This letter agreement may be signed in individual
counterparts, each of which together shall constitute a legal, valid and
binding agreement among the parties.

                             MODIFICATION AGREEMENT

     This Modification Agreement ("Agreement") is entered into as of July 1,
1997 by and among Amsterdam Equities Limited ("Amsterdam"), Frank Leonard
Laport ("Laport"), Beverly Trust Company, as Custodian of the Frank Leonard
Laport Rollover IRA #75-49990 ("Laport IRA", and, collectively with Amsterdam
and Laport, the "Investor Group"), and Princeton Dental Management Corporation
("PDMC").

     WHEREAS, Amsterdam and PDMC have previously entered into that certain
Convertible Debt Agreement dated as of April 22, 1996 ("Convertible Debt
Agreement"), pursuant to which PDMC delivered to Amsterdam that certain
$13,050,000 Convertible Secured Note ("Convertible Note"), and that certain
Warrant to Purchase up to 3,588,750 shares of common stock of PDMC ("Amsterdam
Default Warrant").

     WHEREAS, Amsterdam, Laport, Laport IRA and PDMC have previously entered
into that certain Series A 11.75% Cumulative Convertible Preferred Stock
Purchase Agreement dated as of April 22, 1996 ("Series A Agreement"), pursuant
to which PDMC delivered to Laport that certain Warrant to Purchase up to
134,063 shares of common stock of PDMC ("Laport Default Warrant"), and pursuant
to which PDMC delivered to Laport IRA that certain Warrant to Purchase up to
134,062 shares of common stock of PDMC ("Laport IRA Default Warrant"), and
pursuant to which PDMC delivered to Amsterdam that certain Warrant to Purchase
up to 268,125 shares of common stock of PDMC ("Amsterdam Series A Default
Warrant").

     WHEREAS, PDMC has been advised by The Nasdaq Stock Market, Inc. that PDMC
does not currently meet the listing standards required for continued listing on
the Nasdaq SmallCap Market ("Nasdaq SmallCap").

     WHEREAS, PDMC has advised the Investor Group that, in an effort to meet
the listing requirements of the Nasdaq SmallCap and remain listed on the Nasdaq
SmallCap, PDMC is requesting that the Investor Group agree to certain
modifications of the Convertible Debt Agreement, the Convertible Debt Note and
the Series A Agreement.

     WHEREAS, PDMC acknowledges that the Convertible Debt Agreement, the
Convertible Debt Note and the Series A Agreement are each currently in a state
of default, and any and all amounts due and owing under such agreements are due
upon demand.

     NOW, THEREFORE, for good and valuable consideration, the receipt and
sufficiency of which are hereby acknowledged, the parties hereto agree as
follows:

     1. Convertible Debt Agreement. Amsterdam agrees to waive any and all
accrued and ongoing interest payments as may be due to Amsterdam pursuant to
the Convertible Debt Agreement and/or the Convertible Debt Note for the period
from January 1, 1997 through December 31, 1997 (the "Waiver Period"). Amsterdam
agrees that interest will not accrue during the Waiver Period and that interest
will not begin to accrue until January 1, 1998, at which point interest will
again begin to accrue in strict accordance with the terms of the Convertible
Debt Agreement. Provided, however, that the parties acknowledge that this
Agreement is being entered into, in part, in consideration of (i) a waiver of
any accrued and





<PAGE>   2
ongoing interest as may be due for the period from July 1, 1997 though June 30,
1998 pursuant to that certain Acquisition Promissory Note in the initial
principal amount of $1,350,000 executed by PDMC in favor of the constituent
shareholders of Mason Dental, Inc. and dated as of December 31, 1993 ("Island
Group Waiver"), and (ii) the continued listing of PDMC on the Nasdaq SmallCap
Market ("Nasdaq Listing"), and, in the event that either the Island Group
Waiver or the Nasdaq Listing terminate for any reason whatsoever during the
Waiver Period, then, in such event, Amsterdam may, at its sole and exclusive
option, immediately deem this Modification Agreement void ab initio and of no
force and effect.

     2. Series A Agreement. The Investor Group, and each of them,  agree to
waive any and all accrued and ongoing dividend payments as may be due to any of
the Investor Group pursuant to the Series A Agreement for the Waiver Period.
The Investor Group, and each of them, agree that dividend payments will not
accrue during the Waiver Period and that dividend payments will not begin to
accrue until January 1, 1998, at which point dividend payments will again begin
to accrue in strict accordance with the terms of the Series A Agreement.
Provided, however, that the parties acknowledge that this Agreement is being
entered into, in part, in consideration of (i) the Island Group Waiver, and
(ii) the Nasdaq Listing, and, in the event that either the Island Group Waiver
or the Nasdaq Listing terminate for any reason whatsoever during the Waiver
Period, then, in such event, the Investor Group, or any of them, may, at their
sole and exclusive option, immediately deem this Modification Agreement void ab
initio and of no force and effect.

     3. Default Warrants. PDMC agrees and acknowledges that each of the
Amsterdam Default Warrant, the Amsterdam Series A Default Warrant, the Laport
Default Warrant and the Laport IRA Default Warrant (collectively, the "Default
Warrants") has been effective since January 1, 1997 and that no further action
whatsoever is required in order to render the Default Warrants, or any of them,
effective. PDMC further agrees that, effective immediately and without need for
further action, the "Exercise Price", as such term is defined in each of the
Default Warrants, is reduced from Ten United States Cents ($0.10) per Share (as
such term is defined in the Default Warrants) to One United States Cent ($0.01)
per Share. The parties agree and acknowledge that this reduction in the
Exercise Price of the Default Warrants was an absolute precondition of the
waiver of interest and dividends on the part of the Investor Group, and that
the Investor Group would in no event have agreed to any such waiver without
such a reduction.

     Consistent with the terms of Section 8 of each of the Default Warrants,
PDMC also agrees and reaffirms that it shall be solely liable for any and all
United States, state, local or any other taxes as may be due and owing as a
result of or in any way connected to (i) the issuance of the Default Warrants,
or any of them, (ii) the exercise of the Default Warrants, or any of them,
and/or (iii) the reduction in the Exercise Price of each of the Default
Warrants, or any of them, pursuant to this Agreement.

     Except to the extent and as specifically modified by this Agreement, the
Convertible Debt Agreement, the Convertible Note, the Series A Agreement, the
Default Warrants and any and all other documents entered into in connection
with such documents (the "Investor Group





<PAGE>   3
Documents") remain unchanged and are hereby ratified and reaffirmed in their
entirety. Except as specifically set forth in this Agreement, the terms which
are used in this Agreement shall have the meanings given to them in the
Investor Group Documents and the terms and conditions of the Investor Group
Documents are incorporated into this Agreement in their entirety.

     The parties hereto agree that no further action is required in order to
effectuate the agreements set forth in this Agreement, but, in the event that
counsel for the Investor Group or PDMC reasonably determines that any such
additional documentation is required in order to properly effectuate such
agreements, each of the parties agree to cooperate in this regard and to
immediately execute any additional required documentation.

     This Agreement may be executed in 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 taken together shall constitute one and the
same agreement.

                            NOTE AND LOAN AGREEMENT

Bridgeview, Illinois                                  Date:  As of July 15, 1997


     FOR VALUE RECEIVED the undersigned, Lawrence Ceraulo and Victor Texidor,
and Certex Dental Studio, Inc. (the "Makers") promise to pay to the order of
Mason Dental Southeast, Inc., together with any successors or assigns (the
"Holder"), at 7421 W. 100th Place, Bridgeview, Illinois 60455-2442 or such
other place as Holder may designate from time to time hereafter (hereinafter
referred to as the "Location"), the principal sum of Ninety-Six Thousand Three
Hundred Fifty-Seven and 38/100 Dollars ($96,357.38) - hereinafter referred to
as the "Principal Obligation".

     The Principal Obligation unpaid from time to time shall bear interest from
July 15, 1997 until paid, computed at a daily rate equal to the daily rate
equivalent of Fourteen and three-quarters percent (14.75%) per annum
(hereinafter referred to as the "Stated Rate") computed on the basis of a
360-day year and actual days elapsed, (the Principal Obligation and interest
due at the Stated Rate are hereinafter referred to as the "Makers Primary
Indebtedness").  Makers' Primary Indebtedness shall be payable in accordance
with the amortization schedule attached hereto as Exhibit A, which has been
initiated by the Makers and is incorporated herein and made a part hereof.  All
payments on account of Makers Primary Indebtedness shall be applied first to
accrued and unpaid interest and the remainder to principal. Each date that a
payment is due hereunder, as is set forth on Exhibit A, is hereinafter referred
to as the "Due Date".  Any accrued but unpaid principal and interest still due
and owing shall be paid in full on July 14, 1998.  If this Note, or any
obligation hereunder, is not paid to the Holder when due, then the Principal
Obligation unpaid from time to time shall bear interest from the Due Date until
paid at the highest interest rate permitted by law on the Due Date (hereinafter
referred to as the "Adjusted Stated Rate").  The foregoing notwithstanding, the
Adjusted Stated Rate shall be capped at a rate of ten percent (10%) over the
Stated Rate; and, if by operation of the immediately preceding sentence, the
Adjusted Stated Rate exceeds a rate of ten percent (10%) over the Stated Rate,
the  Adjusted Stated Rate shall be reduced to a rate equal to ten percent (10%)
over the Stated Rate.  The Makers' Primary Indebtedness and interest due at the
Adjusted Stated Rate is hereinafter referred to as "Makers' Secondary
Obligation".

     Interest shall be payable by Makers to Holder with the Principal
Obligation of Makers' Primary Indebtedness, as applicable by the terms hereof,
or as billed by Holder to Makers, at the Location.

     To secure this Note, the Makers hereby grant to the Holder a security
interest in all of the assets, inventory, accounts receivable and accounts of
the Makers and any sole proprietorship, partnership, corporation and other
entity in which and to the extent of which they have an interest therein and
their affiliates, whether now owned or hereafter acquired, and all immediate
and remote proceeds thereof.  Such security interest shall only be subject to
presently existing, secured debt of the Makers.  The Makers agree to
immediately take all necessary actions, and to execute any necessary filings,
to secure such security interest, and to provide the Holder with proof thereof.
The Makers hereby acknowledge that they have




<PAGE>   2
induced the Holder to accept this Note by their specific representation to the
Holder that they, neither individually or collectively, shall ever cause the
security by which this Note is to be secured, currently and in the future, to
be impaired in any way including, by way of illustration and not limitation, by
sale, assignment, concealment, removal and /or otherwise.  Should the security
by which this Note is to be secure, currently and in the future, become
impaired, the Makers agree that such impairment shall constitute an Event of
Default, hereinafter defined.

     Makers warrant and represent to Holder that the debt represented by this
Note was incurred solely for proper business purposes, and consistently with
all applicable laws and statutes.

     The occurrence of any one of the following events shall constitute and
default by Makers (hereinafter referred to as the "Event of Default") under
this Note: (a) if Makers fail to pay Makers' Primary Indebtedness when due and
payable; or (b) if Makers fail to perform, keep or observe any term, provision,
condition, covenant, warranty or representation contained in the Note which is
required to be performed, kept or observed by Makers.

     The Holder shall be entitled to receive payment in full of all interest
accruing hereon subsequent to the filing of a petition or the taking of any
other action commencing a bankruptcy or other similar proceeding or which would
accrue but for such proceeding or action of the under signed.

     Upon an Event of Default hereunder, without notice by Holder to or demand
by Holder of Makers, subject to the Holder's sole and absolute election, all of
Makers' Primary Indebtedness shall be due and payable forthwith hereunder and
all remedies, including the remedies provided herein and any others by law and
equity, shall be available to the Holder.  The acceptance by Holder of any
partial payment make hereunder after the time when any of Makers' Primary
Indebtedness become due and payable will not establish a custom, or waive any
rights of Holder to enforce prompt payment hereof: presentment, protest,
default, non0peyment, maturity, release, compromise, settlement, extension,
renewal of this Note and all other notices except as herein specifically
provided.

     Makers agree to pay, upon Holder's demand therefor, any and all costs,
fees and expenses (including, solely by the way of illustration and not
limitation, attorneys' fees, costs and expenses) incurred in enforcing any of
Holder's rights, hereunder, and to the extent not paid the same shall become
part of Makers' Primary Indebtedness hereunder.

     Makers hereby authorize, irrevocably, any attorney of any Court of Record
in any state or territory of the United States where the same is allowed by
law, in term time or vacation, at any time after occurrence of an Event of
Default hereunder, to appear for Makers, to waive the issuance and service of
process, and confess a judgement against the Makers for the amount of Makers'
Secondary Obligation due hereunder, including all casts, fees and expenses as
provided herein, further authorizing said attorney to waive and release all
errors which may intervene in any such proceeding and waive all right of appeal
and consent to immediate execution upon such judgement, hereby agreeing that no
writ of error or appeal will be prosecuted from such judgement, nor any bill in
equity filed to retrain the operation of said judgment, or any execution
thereon, and hereby ratifying and confirming all that said attorney may do by
virtue hereof.  If this provision or any other provision of this Note or the
application thereof to any party or circumstance is held invalid or
unenforceable, the remainder of this
