                    PRINCETON DENTAL MANAGEMENT CORPORATION
            NOTES TO THE CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
                               SEPTEMBER 30, 1998
                                  (UNAUDITED)


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.

         The Company had a one-to-five reverse stock split of its common stock
effective August 18, 1997.  All share information and per share information in
these consolidated financial  statements have been retroactively restated to
reflect the reverse stock split.

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 could choose to 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 interest began to accrue at the default rate of 21.75%.

         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 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.  That waiver ended on January 1,
1998, and interest and dividends have again been accruing.

                                  (UNAUDITED)



         The waiver of interest and dividends during 1997 on the part of the
Investor Group resulted 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 58,333 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 were held in treasury after the redemption.

         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 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, and
exercise the default warrants (see below), the conversion would result in the
issuance to the Investor Group of a majority interest of the issued and
outstanding shares of Company's common stock (after conversion and 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 number of shares of common
stock equivalent to fifty percent (50.0%) of the issued and outstanding Common
Stock of the Company at an exercise price of $0.10 per share (subsequently
reduced to $0.01 per share under the terms of the Modification Agreement). This
modification effectively reduced the aggregate exercise price of approximately
$412,500 for the default warrants to an aggregate exercise price of
approximately $41,250 (not accounting for any adjustments due to the
anti-dilution provision of the Warrants and due to changes in the total issued
and outstanding shares of the Company's common stock).  Initially, 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 various net income tests
in subsequent years. 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 a minimal exercise price 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 outstanding Convertible Debt/Preferred
Stock could result in ownership by

the Investor Group of a majority of the Company's total issued and outstanding
common stock after such conversion and exercise.

         Effective as of November 4, 1998, the Company was advised that (i)
Amsterdam Equities Limited had transferred any and all interest which they had
in the default warrants to Frank Leonard Laport, and (ii) that Mr. Laport had
proceeded to exercise such default warrants.  Exercise of all of the default
warrants for the stated exercise price will result in Mr. Laport receiving
approximately 1,065,483 additional shares of Company 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 has 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.  Effective as of August 9, 1996, the Investor Group 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.

            NOTES TO THE CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

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 period ended
December 31, 1997.

Results of Operations

     Revenue for the nine month period ended September 30, 1998 was $9,028,798
compared with $11,028,039 for the nine month period ended September 30, 1997, a
decrease of $1,999,241 (18.13%).  The change in revenue is due primarily to the
sale of three dental practices and one dental laboratory during 1997 and a
reduction of production at the dental practices.  Operating expenses decreased
$1,625,714 (a decrease of 14.84%) to $9,327,362 for  the  nine  month  period
ended  September 30, 1998  from $10,953,076  for  the  nine  month period ended
September 30, 1997. This decrease is due in large part to the sales of the
practices and the dental laboratory, as well as several cost cutting measures
related to compensation, benefits, and various other practice expenses.

     Interest expense increased $458,107 to $651,293 for the nine month period
ended September 30, 1998 versus $193,186 incurred in the comparable nine month
period last year.  The increase is primarily the result of the Modification
Agreement and the Allonge (see Exhibits 10.55 and 10.56) having a material
positive effect upon the Company's interest expense in 1997.

     The net loss for the nine month period ended September 30, 1998 was
$934,010. The net loss increased by $1,143,364 when compared with the nine month
period ended September 30, 1997.  This increase in the net loss is primarily due
to the elimination of the practice sales gain, reduced production, increased
amortization and the Modification Agreement and the Allonge having a positive
effect upon the Company's interest expense in 1997.  (See Exhibits 10.55 and
10.56).


Financial Condition

     The Company continues 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 a
significant 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 the past the Company did not pay certain state tax liabilities in the
State of Michigan.  Currently the Company is in the process of negotiating with
the State to abate penalties with respect to the late payment.  The Company
estimates its total liability in this regard to be $175,000.

     Given the Company's recurring losses from operations, the significant
working capital deficits and  the uncertainty in obtaining additional funding to
provide working capital in the short term,  a substantial doubt has been raised
as to the Company's ability to continue as a going concern absent significant
improvement in operations or significant additional funding.

            NOTES TO THE CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
                               SEPTEMBER 30, 1998
                                  (UNAUDITED)



Liquidity and Capital Resources

     As of September 30, 1998, the Company had a working capital deficit of
$4,385,138 and a financial accumulated deficit of $14,656,701.  Goodwill and
other intangibles comprise approximately 69% of total assets, leaving tangible
assets of approximately $2,248,939 and negative tangible net worth of
approximately $4,793,074.

     During the nine month period ended September 30, 1998, the Company's cash
and cash equivalents increased $235,551.  Cash generated from depreciation and
amortization was $626,631.

     Many computer systems in use today were designed and developed using two
digits, rather than four to specify the year.  As a result, such systems may
recognize the year 2000 as 00.  This could cause many computer applications to
fail completely or to create erroneous results unless corrective measures are
taken.   The Company utilizes software and related computer technologies
essential to its operations that may be affected by the Year 2000 issue.  The
Company has reviewed the Year 2000 problem as it relates to the Company's
internal system and does not believe at this time that it will have a material
impact upon its business, operations or financial condition.  However, the
Company's review is continuing and the Company can make no absolute assurances
in this regard.

     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.  The Company has not needed to obtain additional material amounts of
funding from the Investor Group during the past year but remains in an ongoing
state of default under the terms of the Financing Arrangement.  If the Investor
Group was to call a formal default on the Preferred Stock/Convertible Debt
issued by the Company, the Company would have no means of curing such default.


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.  While the
              Company is appealing this decision, the Company received an
              adverse judgement in that suit in October, 1997 and has paid
              Romajo Partners Limited Partnership $162,627 as the judgement
              amount.

         b)   On June 12, 1998, the Company sued Dr. Charles Mitchell, a former
              officer and director of the Company, and Stratum Management, Inc.
              an affiliate of Dr. Mitchell and a former consultant to the
              Company, for breach of contract and breach of fiduciary duty.
              That lawsuit is still pending.

         c)   In October,  1998,  the  Company  obtained  judgement in  a
              lawsuit  brought,  in April 1998,  against Dr. Richard Sokol, a
              former officer and director of the company, and Lawrence Ceraulo
              and Primecast Dental, former contractors for the Company, for
              breach of contract and breach of fiduciary duty.  The Company is
              in the process of seeking to enforce such judgement.

         d)   The Company is the defendant in several pending employee
              discrimination and vendor/creditor law suits in which it is the
              defendant.  Such law suits include law suits bought against the
              Company  by (i) J.F. Jelenko & Co. claiming $90,338 owed; (ii)
              Office Max/Office Depot claiming $25,000 owed; (iii) Chuhak &
              Tecson claiming  approximately $50,000; (iv) a class action
              discrimination suit bought against the Company in Michigan seeking
              unspecified damages; and (v) a sexual discrimination suit bought
              against the Company in Florida seeking unspecified damages.  The
              Company is vigorously defending these lawsuits.

                                  (UNAUDITED)



         e)   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 2.  Changes in Securities

         a)   Effective August 18, 1997, the Company's shareholders approved a
              one-to-five reverse Stock split of the company's common stock.

         b)   Sales of Unregistered Securities.

              1.   Effective as of July 13, 1998, the Company issued 45,000
                   shares of unregistered restricted common stock of the Company
                   to Mr. Ronald J. Frank for a total consideration of $48,750
                   in a private  placement exempt from registration pursuant to
                   Section 4(2) of the Securities Act of 1933.

              2.   Effective as of July 28, 1998, the Company issued 45,000
                   shares of unregistered restricted common stock of the Company
                   to Mr. Len J. Shapiro for a total consideration of $48,728.34
                   in a private placement exempt from registration pursuant to
                   Section 4(2) of the Securities Act of 1933.

              3.   Effective as of November 4, 1998, the Company was advised
                   that (i) Amsterdam Equities Limited had transferred any and 
                   all interest which they had in certain default warrants (See
                   Note 3 above) to Frank Leonard Laport, and (ii) that Mr.
                   Laport had proceeded to exercise such default warrants.  The
                   default warrants in question have been outstanding since
                   April, 1996 and were issued in connection with debt
                   outstanding since December, 1994.  The exercise of such
                   default warrants will result in Mr. Laport receiving
                   approximately 1,065,483 shares of unregistered restricted
                   common stock of the Company for an aggregate exercise price
                   of $41,250.  The issuance of the Common Stock is exempt from
                   registration requirements pursuant to Section 4(2) of the
                   Securities Act of 1933.

Item 3.  Defaults Upon Senior Securities

         a)   While no formal default has been called to date by the Investor
              Group (See Note 3 above), the Company has failed to pay any of the
              interest and/or dividend payments called for under the Financing
              Arrangement (See Note 3 above) and could be considered in a state
              of ongoing default with respect to the Financing Arrangement.  If
              the Investor Group was to call a formal default with respect to
              the Preferred Stock/Convertible Debt issued by the Company to the
              Investor Group, the Company would have no means of curing such a
              default.

Item 5.  Other Information

         a)   Effective as of July 1, 1998 the Company entered into that certain
              Allonge and Amendment to Balloon Promissory Note and All Related
              Agreements with Dr. Glenn C. Lehr and certain related entities.
              This Agreement serves to restructure the debt owed by the Company
              in connection with the Amdent practices.  (See Exhibit 10.61).

         b)   Effective as of October 15, 1998, the Company was informed by The
              Nasdaq Stock Market,Inc. ("Nasdaq") that the Company's securities
              would be delisted from the Nasdaq SmallCap Market effective at the
              close of business on October 15, 1998 due to the inability of the
              Company to meet the Nasdaq listing requirement that the Company
              maintain at least $2,000,000 in net tangible assets.

         c)   Effective as of November 4, 1998, the Company was advised that (i)
              Amsterdam Equities Limited had transferred any and all interest 
              which they had in the default warrants to Frank Leonard Laport,
              and (ii) that Mr. Laport had proceeded to exercise such default
              warrants. Exercise of all of default warrants for the stated
              exercise price will result in Mr. Laport receiving approximately
              1,065,483 additional shares of Company Common Stock.

(b) Reports on Form 8-K    The Registrant filed the following Form 8-K's during
the  period  from January 1, 1998 through November 1, 1998:


         1)   Effective as of July 14, 1998, PDMC announced that it had entered
              into a Financial Consulting Agreement with BullsEye Marketing,
              Inc.

              The Agreement anticipated that BullsEye Marketing, Inc. would
              assist PDMC in generally building market awareness of PDMC.  As
              specified in the Agreement, (see Exhibit 10.60), PDMC would pay
              the consultant $1,000 per month plus reasonable expenses and issue
              250,000 warrants to the consultant.  The warrants would be
              exercisable at the same exercise price as the current publicly
              held warrants.


         2)   Effective as of September 18, 1998, PDMC announced that the Board
              of Directors of Princeton Dental Management Corporation ("PDMC")
              had announced that the expiration date of those certain warrants
              issued pursuant to that certain Warrant Agreement dated April 15,

              from the Nasdaq SmallCap Market effective at the close of business
              on October 15, 1998 due to the inability of the Company to meet

              $2,000,000 in net tangible assets.
