anti-dilution, and a right of first refusal on any future offering of the
Company's securities.

Under the terms of the transaction, the Company has issued a warrant to
purchase 100 shares of Series B Preferred Stock.  The Series B Preferred Stock
entitles Amsterdam Equities Limited, after the occurrence of an event of
default, to elect a Class B director who will 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, as the sole option of
the Group, at various conversion rates as set forth in the conversion formula
contained in the Convertible Debt and Preferred Stock Agreement.  Conversion
pursuant to such conversion formula would result in a conversion price per
share of the Company's common stock significantly below present market levels.
If the Group were to convert the Convertible Debt and Preferred Stock at the
present time, the conversion would result in the issuance to the Group of
approximately 9,600,000 shares of the Company's common stock, representing
approximately forty-two percent (42%) 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
has issued to the holders of the Convertible Debt and the Preferred Stock a
warrant to purchase shares of common stock at an exercise price of $.10 per
share.  The Group may exercise the warrant only upon the occurrence of an event
of default under the terms of the 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 can make no assurances that such financial goals
can be achieved by the Company.  The cumulative effect of the issuance of
shares pursuant to the default warrant to the Group could result in ownership
by the Group of up to 75% of the Company's total issued and outstanding common
stock.

Note 4 - CONSULTING AGREEMENT

The Company had entered into an agreement with Stratum Management, Inc. and
certain individual consultants (collectively, the "Consultants") for consulting
services, terminable by either party at any time.  The Consultants were to
provide the Company with operations management, provider relations, systems
development, standardization and development of operations manuals, marketing
analysis and development, strategic alliances development and re-acquisition
evaluation services. The board of directors of the Company had final approval
of all actions of the Consultants.  In addition to consulting fees
approximating $41,000 per month in 1996, the Consultants were issued warrants
to purchase up to 600,000 shares of the Company's common stock at an exercise
price of $1 per share expiring December 31, 1998.  Subsequently, in July 1996
the Warrants Agreement was amended to reduce the number of warrants available
from 600,000 to 388,000 as a condition of the financing agreement disclosed in
Note 5.  This consulting agreement was terminated by the Company effective
August 1, 1996.

Dr. Charles R. Mitchell, who was appointed as President of the Company
effective October 26, 1995, was originally affiliated with the consultants.
While Dr. Mitchell has reported to have severed all direct ties with the
Consultants in conjunction with his appointment as President of the Company and
has reported to have received no compensation from the Consultants, Dr.
Mitchell's wife remains a shareholder in, and an employee of, Stratum
Management, Inc., which is directly affiliated with the Consultants.  As a
condition of the financing agreement disclosed in Note 5, Dr. Mitchell resigned
as President and CEO of the company and is performing limited functions as a
consultant.

Note 5 - SUBSEQUENT EVENTS

Subsequent to June 30, 1996, the Company entered into a Letter Agreement by and
among the Company;  Dr. Charles R.  Mitchell, the President of the Company;
Stratum Management, Inc. ("Stratum"), a consultant to the Company;  John H.
Hagan, a director of the Company;  Dr. Seymour Kessler, a director of the
Company; and Amsterdam Equities, Ltd.  ("Amsterdam"), Frank Leonard Laport, and
Beverly Trust Company, as Custodian of the Frank Leonard Laport Rollover
Individual Retirement Account No. 75-49990, each member of the investment group
(the "Investor Group").  Under the Letter Agreement, which became effective on
August 9, 1996, the Series B Preferred Stock referred to in the Convertible
Debt Agreement executed by the Company on April 22, 1996 (see Note 3) was to be
amended to be immediately effective and Class B Preferred Stock was
immediately issued to Amsterdam.

Note 5 - SUBSEQUENT EVENTS (Cont'd)

The Class B Preferred Stock entitled Amsterdam to elect a Director to the Board
of Directors of the Company who shall 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 on a
pro rate basis, 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 U.S. $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 has satisfied these two conditions and the Class B Preferred
Stock has been issued to Amsterdam.

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

In connection with the above, Dr. Mitchell has resigned as President of the
Company, but will continue to assist the Company in the transition to a new
management team.  Dr. Mitchell, Dr. Kessler, and John Hagan will stay as
directors until the Company's annual meeting.  Gary Lockwood, Dr. Richard
Staller, Frank Leonard Laport, Esq. and George Collins, Esq., who also acts as
attorney in fact for Amsterdam Equities Limited, have been appointed to the
Board to fill vacancies created by an increase in the number of directors.

Gary Lockwood, President of Mason Dental Laboratories, a subsidiary of the
Company, has been appointed as President of the Company.  Frank Leonard Laport
has been elected as Chairman of the Board of Directors of the Company.  Frank
Leonard Laport has also been elected as the Series B director by Amsterdam
Equities Limited.

Effective September 16, 1996, the Company relocated its corporate offices to
7421 West 100th Place, Bridgeview, Illinois.

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, 1995.

Results of Operations

Revenue for the six month period ended June 30, 1996 was $9,427,504 compared
with $8,712,159 for the six month period ended June 30, 1995, an increase of
$715,345.  The change in revenue is due to an increase in production throughout
the Company.





                                       10

                    PRINCETON DENTAL MANAGEMENT CORPORATION
              NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

                                 JUNE 30, 1996
                                  (UNAUDITED)


Operating expenses increased $1,786,376 to $10,286,173 for the six month period
ended June 30, 1996 from $8,499,797.  This increase is attributable primarily
to the increased production previously mentioned.

Interest expense increased $93,855 to $309,486 for the six month period ended
June 30, 1996 versus $215,631 incurred in the comparable six month period last
year.  The increase is primarily the result of additional advances during 1995
under the Revolving Demand Note which was subsequently rolled into the
Convertible Debt and Preferred Stock Agreement.


The net loss for the six month period ended June 30,1996 of $1,142,965 is
primarily the result of the increase in payroll cost to provide patient
services as well as costs incurred for outside consulting services.

The Company is currently in the process of developing revenue enhancement
programs for the practices and laboratories.  The Company is also working to
improve the operating results of the various operations by reducing costs of
patient services and laboratory costs.  The Company has begun steps to reduce
general and administrative expenses by eliminating substantially all outside
consulting arrangements which totaled approximately $302,000 for the six months
ended June 30, 1996.   However, the Company can make no assurances in regards
to the results of these programs.

Financial Condition

Changes in the Company's financial condition at June 30, 1996 as compared with
December 31, 1995 resulted primarily from the Company's results of operations
for the six month period ended June 30, 1996.

During the first and second quarters of 1996, the Company did not deposit
certain state payroll tax liabilities totaling approximately $53,000. The
company is currently negotiating with the State to pay the payroll obligations
in monthly installments and to abate penalties associated with the late
payment.  In addition, during 1994 the Company did not make certain federal
payroll tax deposits on a timely basis and is in the process of negotiating
with the IRS to abate penalties associated with these late filings.  Management
has provided a reserve of approximately $60,000 for the state tax liability and
penalties and $70,000 to cover the IRS penalties should the IRS ruling be
unfavorable.  Management believes these reserves are sufficient to cover these
obligations.

Liquidity and Capital Resources

As of June 30, 1996, the Company has a working capital deficit of $4,544,654
and a financial accumulated deficit of $9,124,551.  Goodwill and other
intangibles comprise approximately 80% of total assets, leaving tangible assets
of approximately $2,916,536 and negative tangible net worth of ($6,346,719).

              NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

                                 JUNE 30, 1996
                                  (UNAUDITED)


During the six month period ended June 30, 1996, the Company's cash and cash
equivalents decreased $90,699.  Cash provided by operations was $217,291
resulting primarily from the Company's increase in accounts payable and accrued
expenses for the period of $996,569 of which this increase was partially offset
by depreciation and amortization of $487,251, $88,979 of costs associated with
the issuance and redemption of the Company's common stock, and a net increase
in accounts receivable of $235,364.

Investing activities utilized $145,094 of cash primarily related to the
acquisition of property and equipment for $117,275 and debt issuance costs of
$27,819.  Cash of $162,896 was used by financing activities primarily as a
result of debt principal payments of $194,722, net of proceeds from issuance of
debt of $31,826.

As disclosed in Note 3 and Note 5, the Company's primary source of outside
financing is from the Investor Group, which has agreed to lend up to $15
million if certain conditions are met.  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
some extent, provide working capital to fund the operations.  The Company can
make no assurances the Company will be able to meet the requirements to obtain
the additional financing in the increments required.


PART II - OTHER INFORMATION

Item 1.   Legal Proceedings

          a.   On June 14, 1995, the Company filed a complaint for declaratory
relief against Messrs. Terry D. Gingle and Oscar L. Hausdorff (the "Gingle
Group"), certain former members of senior management, regarding an alleged
pledge of shares of Company Common Stock to the Group.  While the Gingle Group
is contesting such pledge, the Company and the Gingle Group have entered into a
temporary standstill agreement whereby neither party will take any immediate
action while attempting to negotiate settlement with respect to this issue.

         b.   The Company is involved in a number of 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.  Management believes settlements, if any, in excess of insurance
coverage would be immaterial.

arrangement pursuant to which the Company issued Convertible Debt (the

The amendment and activation of the Class B Preferred Stock was to occur upon
the satisfaction of the following two conditions:  (i) delivery to the Company
of a notice, pursuant to which the Investment Group would convert on a pro rate
basis, an aggregate amount of U.S. $700,000.00 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 U.S. $200,000.00 pursuant to the Convertible Debt and the
Preferred Stock Agreements executed April 22, 1996.  As of August 9, 1996, the
Investment Group has satisfied these two conditions and the Class B Preferred
Stock has been issued to Amsterdam.

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

In connection with the above, Dr. Mitchell has resigned as Chief Executive
Officer and President of the Company, but will continue to assist the Company
in the transition to a new management team.  Dr. Mitchell will stay on as a
director until the Company's next annual meeting is held, which is scheduled to
take place on September 27, 1996.  Hagan and Kessler would also continue to
serve as directors until the Company's next annual meeting.  Gary Lockwood, Dr.
Richard Staller, Frank Leonard Laport, Esq.  and George Collins, Esq. have been
appointed to the Board to fill vacancies created by an increase in the number
of directors.

Gary Lockwood, President of Mason Dental Laboratories, a subsidiary of the
Company, has been appointed as President of the Company.  Mr. Lockwood will
continue to serve in his role as President of Mason Dental in addition to his
new duties as President of the Company.  Frank Leonard Laport has been elected
as Chairman of the Board of Directors of the Company.

In connection with the letter agreement transaction, the Company shall relocate
its principal offices to another location in the Chicago metropolitan area on
or about September 30, 1996.

                 (a)      Salary.  The Company shall pay to Employee as
                          compensation for all services rendered by Employee
                          under this Agreement during the Term, a base salary
                          ("Salary") of Ninety-Six Thousand Dollars ($96,000)

                 (b)      Stock.  The Company shall issue to Employee,
                          effective upon the signing of this Agreement, 50,000
                          shares of Company stock under the Company's 1993
                          Incentive Stock Plan.

                 (c)      Fringe Benefits.  Employee, (including Employee's
                          spouse and minor children) shall be entitled to

                          insurance plan coverage.  If Employee chooses not to
                          participate in the Company's life insurance or
                          medical plans, the Company shall reimburse Employee
                          for his cost in obtaining such coverage; provided
                          that the reimbursement of such costs shall not exceed
                          the amount paid on behalf of Employees participating
                          in such plans.

                 course of employment duties and paid by Employee on behalf of
                 the Company; such reimbursement shall not be deemed to be
                 compensation.  Reimbursement shall be made following
                 submission by Employee to the Company of such vouchers as may
                 be reasonably satisfactory to the Company.  In the event
                 Employee is issued a Company credit card, Employee agrees to
                 use same for Company business only, and not for any other
                 business or personal use.  Employee shall complete a report of
                 accounting on a timely basis with respect to any and all of
                 the charges incurred under such credit card. In the event
                 Employee breaches this Agreement and uses a Company credit
                 card for personal use, Company shall have the right to
                 withhold such amount directly from Employee's paycheck or any
                 other amounts due and payable to Employee, in cash or in kind.

         5.      VACATION.

                 of this Agreement, the number of continuous days of vacation
                 shall not exceed ten (10) days.

          6.     RESTRICTIVE COVENANT; PROPRIETARY RIGHTS; CONFIDENTIALITY

                          any other entity, which, whether directly or
                          indirectly, competes with the Company in any fashion

                          construed to prohibit or limit in any way Employee
                          from investing in the Company or any class of

                 (b)      Employee shall not, directly or indirectly, upon the
                          termination of Employee's employment hereunder and
                          (i) for a period of two (2) years after such
                          termination, solicit the patients, employees, agents,

                          Company in the Area, or (ii) for a period of six (6)
                          months after such termination, become a consultant,
                          partner, member, employee, agent, advisor or

                          that nothing in this paragraph or this Agreement
                          shall be construed to prohibit or limit in any way

                          percent of any class of securities of such

                 (d)      Employee acknowledges the Company's exclusive 
                          ownership of all information useful in the Company's
                          business (including it's dealings with suppliers,
                          customers, and other third parties, whether or not a
                          true "trade secret"), which at the time are not
                          generally known to persons engaged in businesses
                          similar to those conducted by the Company, and which
                          has been or is from time to time disclosed to, or
                          otherwise known by Employee as a consequence of
                          employment at any time by the Company (collectively,
                          "Confidential Information").

                 (e)      Employee further acknowledges the Company's exclusive
                          ownership of all business records, documents,
                          drawings, writings, software, programs, and other
                          tangible things which were or are created or received
                          by or for the Company in furtherance of its business,
                          including, but not limited to, those which contain
                          Confidential Information (collectively, "Proprietary
                          Materials").  While some of the information contained
                          in Proprietary Materials may have been known to
                          Employee prior to employment with the Company, or now
                          or in the future be in the public domain, Employ
                          acknowledges that the compilation of that information
                          in Proprietary Materials has or will cost the Company
                          a great effort and expense, and affords persons with
                          whom Proprietary Materials are disclosed, including
                          Employee, a competitive advantage over persons who do
                          not know the information or have the compilation of
                          the Proprietary Materials.


                 (f)      Employee shall during the Term and thereafter for the
                          longest time permitted by applicable law ensure that
                          the Confidentiality Information and Proprietary
                          Materials of the Company are not disclosed to any
                          person, except as permitted by policies and
                          procedures adopted by the Board of Directors of the
                          Company.

                 (g)      Upon the expiration of the Term or termination for
                          whatever reasons, Employee (or in the event of death,
                          Employee's personal representative) shall promptly
                          surrender the Company the original and all copies of
                          Proprietary Materials (including all notes, memoranda
                          and the like concerning it derived therefore) whether
                          prepared by Employee or others, which are then in
                          Employee's possession or control.  Records of
                          payments made by the Company to or for the benefit of
                          Employee, Employee's copy of this Agreement and other
                          such things, lawfully possessed by Employee which
                          relate solely to taxes payable by Employee, employee
                          benefits due to Employee or the terms of Employee's
                          employment with the Company, shall not be deemed
                          Proprietary Materials for purposes of this section.

                 (h)      Consultants understand that the Company would not
                          have an adequate remedy at law for the breach or
                          threatened breach by the Employee of any one or more
                          of the covenants set forth in Section 6 of this
                          Agreement, and agree that, in the event of such a
                          breach or threatened

                          breach, whether before or after the expiration or
                          termination of this Agreement, the Company may, in
                          addition to any other remedies which it may have
                          available to it, at its option (a) enjoin Employee
                          from breach or threatened breach of such covenants,

mean information of any nature and in any form:

                          (i)     which is the property of or used by the

                                  businesses similar to those conducted by the
                                  Company (other than by reason of the act or
                                  acts of any person or entity not authorized
                                  by the Company to disclose such information).

Consultants), of all books, records, computer data, notes, materials, memoranda
and other data pertaining to information of a secret or confidential nature,
which are in his possession at the time of termination of this Agreement or

Company for any business purpose currently competitive with the business of the
Company in the Area, or (ii) for a period of six (6) months after such
termination, become a consultant, partner, member, employee, agent, advisor or
investor, or participate in any manner, with or in any sole proprietorship,
partnership, corporation or any other entity, which, whether directly or
indirectly, makes any such solicitations in any fashion whatsoever in the Area;
provided, however, that this restrictive covenant shall not be construed to
prohibit any activity of a Consultant described on Exhibit C attached hereto,

shall be construed to prohibit or limit in any way any Consultant from
investing in the Company or any class of securities of any corporation that are
listed on a national securities exchange or registered pursuant to Section

market, if such

from time to time hereafter (but only time after the expiration or termination
of Stratum's engagement hereunder by Stratum (other than pursuant to Section

execute and deliver all applications, papers, assignments, conveyances,
instruments or other documents and shall perform or cause to be performed such
other acts as the Company deems necessary or desirable to implement any of the

the Company would not have an adequate remedy at law for the breach or
threatened breach by the Consultants of any one or more of the covenants set
forth in this Section 9, and agree that, in the event of such a breach or
threatened breach, whether before or after the expiration or termination of
this Agreement, the Company may, in addition to any other remedies which it may
have available to it, at its option (a) enjoin any Consultant from breach or
threatened breach of such covenants, or (b) seek damages from any Consultant.

of the termination of the Consulting Agreement or December 31, 1996.  If this
Warrant is exercised in respect of less than all of the shares of Common Stock
at the time purchasable hereunder, the holder hereof shall be entitled to
receive a new Warrant covering the number of shares in respect





                                 Page 14 of 23
<PAGE>   16
of which this Warrant shall not have been exercised; provided, however, that
this Warrant and all rights and options hereunder shall expire at the close of
business on December 31, 1998.  This Warrant and all options and rights
hereunder shall be wholly void to the extent that this Warrant is not exercised
before it expires.

         3.      Reservation of Common Stock.  The Corporation covenants and
agrees that during the period within which the rights represented by this
Warrant may be exercised, the Corporation will at all times have authorized,
and in reserve, a sufficient number of shares of its Common Stock to provide
for the exercise of the rights represented by this Warrant.

         4.      Protection Against Dilution.  The Number of Warrant Shares
deliverable hereunder shall be adjusted as hereinafter set forth:

                 A.       Stock Dividends, Subdivisions and Combinations.  In
         case after the date hereof the Corporation shall:

                          (1)     take a record of the holders of its Common
                 Stock for the purpose of entitling them to receive a dividend
                 payable in, or other distribution of, Common Stock, or

                          (2)     subdivide its outstanding shares of Common
                 Stock into a larger number of shares of Common Stock, or

                          (3)     combine its outstanding shares of Common
                 Stock into a smaller number of shares of Common Stock,

         then the number of Warrant Shares shall be adjusted to that Number of
         Warrant Shares determined by multiplying the Number of Warrant Shares
         which could be purchased hereunder immediately prior to such event by
         a fraction (i) the numerator of which shall be the total number of
         outstanding shares of Common Stock of the Corporation immediately
         after such event, and (ii) the denominator of which shall be the total
         number of outstanding shares of Common Stock of the Corporation
         immediately prior to such event.

                 B.       Other Provisions, Applicable to Adjustments Under
         this Section.  The following provisions shall be applicable to the
         making of adjustments in the Number of Warrant Shares hereinbefore
         provided in this paragraph:

                          (1)     Record Date.  If the Corporation takes a
                 record of the holders of common Stock for the purpose of
                 entitling them (i) to receive a dividend or other distribution
                 payable in Common Stock, or (ii) to subscribe for or purchase
                 Common Stock, then for purposes of this paragraph such record
                 date will be deemed to be the date of the issue or sale of the
                 shares of Common Stock deemed to have been issued or sold upon
                 the declaration of such dividend or upon the making of such
                 other distribution or the date of the granting of such right
                 of subscription or purchase, as the case may be.  If
                 thereafter the





                                 Page 15 of 23
<PAGE>   17
                 Corporation shall have legally abandoned its plan to make such
                 dividend or distribution without having made such dividend or
                 distribution, then the number of shares of Common Stock deemed
                 to have been issued and outstanding shall no longer be computed
                 as set forth in Paragraph 4A above and the Number of Warrant
                 Shares shall forthwith be readjusted and thereafter be the 
                 Number of Warrant Shares which it would have been had the 
                 adjustment of the Number of Warrant Shares been made upon the
                 issuance of such stock dividend rather than the taking of the
                 record of holders with respect thereto.

                          (2)     Treasury Shares.  The number of shares of
                 Common Stock outstanding at any given time does not include
                 shares owned or held by or for the account of the Corporation
                 or any subsidiary, and the disposition of any shares so owned
                 or held will be considered an issue or sale of Common Stock.

                 C.       Adjustment of Purchase Price.  Whenever the Number of
         Warrant Shares hereunder shall be adjusted as set forth in this
         Paragraph 4, the Purchase Price shall be correspondingly adjusted by
         multiplying the Purchase Price then in effect by a fraction, (i) the
         numerator of which shall be the total number of outstanding shares of
         Common Stock of the Corporation prior to such adjustment, and (ii) the
         denominator of which shall be the total number of outstanding shares
         of Common Stock of the Corporation immediately after such adjustment.

                 D.       Notice of Adjustments.  Whenever the Number of
         Warrant Shares purchasable and the Purchase Price shall be required to
         be adjusted pursuant to this Paragraph 4, the Corporation shall
         promptly prepare a certificate signed by the President or a Vice
         President and by the Chief Financial Officer setting forth, in
         reasonable detail, the event requiring the adjustment, the amount of
         the adjustment, the method by which such adjustment was calculated
         (including a description of the basis on which the Board of Directors
         of the Corporation made any determination hereunder), and shall
         promptly cause  copies of such certificate to be mailed (by first
         class mail postage prepaid) to each of the holders of the Warrants.

         5.      Mergers, Consolidations, Sales.  In the case of any
consolidation or merger of the Corporation with another entity, or the sale of
all or substantially all of its assets to another entity, or any reorganization
or reclassification of the Common Stock or other equity securities of the
Corporation (except  a subdivision or combination of the Common Stock provision
for which is made in Paragraph 4A), then, as a condition of such consolidation,
merger, sale, reorganization or reclassification, lawful and adequate provision
shall be made whereby the holders of the Warrants shall thereafter have the
right to receive upon the basis and upon the terms and conditions specified
herein and in lieu of the shares of Common Stock immediately theretofore
purchasable hereunder, such shares of stock, securities or assets as may (by
virtue of such consolidation, merger, sale, reorganization or reclassification)
be issued or payable with respect to or in exchange for a number  of
outstanding shares of Common Stock equal to the number of shares of Common
Stock immediately theretofore so purchasable hereunder had such consolidation,
merger, sale, reorganization or reclassification not taken place, and in any
such case appropriate





                                 Page 16 of 23
<PAGE>   18
provisions shall be made with respect to the rights and interests of the
holders of the Warrants to the end that the provisions hereof (including, but
not limited to, provisions for adjustment of the Number of Warrant Shares and
Purchase Price) shall thereafter be applicable as nearly as may be, in relation
to any shares of stock, securities or assets thereafter deliverable upon
exercise of this Warrant.  The Corporation shall not affect any such
consolidation, merger or sale, unless prior to or simultaneously with the
consummation thereof, the successor entity (if other than the Corporation)
resulting from such consolidation or merger or the entity purchasing such
assets shall assume by written instrument executed and mailed or delivered to
each holder of the Warrants, the obligation to deliver to such holder such
shares of stock, securities or assets as, in accordance with the foregoing
provisions, such holder may be entitled to receive.

         6.      Dissolution or Liquidation.  In the event of any proposed
distribution of the assets of the Corporation in dissolution or liquidation
(except under circumstances when the foregoing Paragraph 5 shall be applicable)
the Corporation shall mail notice thereof to the holders of the Warrants and
shall make no distribution to stockholders until the expiration of 30 days from
the date of mailing of the aforesaid notice and, in any such case, the holders
of the Warrants may exercise the conversion rights with respect to the Warrants
within 30 days from the date of mailing such notice and all rights herein
granted not so exercised within such 30 day period shall thereafter become null
and void.

         7.      Notice of Extraordinary Dividends.  If the Board of Directors
of the Corporation shall declare any dividend or other distribution on its
common Stock except out of earned surplus or by way of a stock dividend payable
on its Common Stock, the Corporation shall mail notice thereof to the holders
of the Warrants not less than 30 days prior to the record date fixed for
determining stockholders entitled to participate in such dividend or other
distribution or be entitled to any rights on account or as a result thereof
unless and to the extent that the Warrants are exercised prior to such record
date.

         8.      Fractional Shares.  Fractional shares shall not be issued upon
the exercise of this Warrant but in any case where the holder hereof would,
except for the provisions of this paragraph, be entitled under the terms hereof
to receive a fractional share upon the complete exercise of this Warrant, the
Corporation shall, upon the exercise of this Warrant for the largest number of
whole shares then called for, pay a sum in cash equal to the Market Price of
such fractional share.

         9.      Fully Paid Stock; Taxes. The Corporation covenants and agrees
that the shares of stock represented by each and every certificate for its
Common Stock to be delivered on the exercise of the conversion rights herein
provided for shall, at the time of such delivery, be validly issued and
outstanding and be fully paid and nonassessable.  The Corporation further
covenants and agrees that it will pay when due and payable any and all federal
and state taxes (other than Income taxes) which may be payable in respect of
the Warrants or any Common Stock or certificates therefor upon the exercise of
the conversion rights herein provided for pursuant to the provisions hereof.





                                 Page 17 of 23
<PAGE>   19
         10.     Closing of Transfer Books.  The right to exercise any Warrant
shall not be suspended during any period while the stock transfer books of the
Corporation for its Common Stock may be closed.  The Corporation shall not be
required, however, to deliver certificates of its Common Stock upon such
exercise while such books are duly closed for any purpose, but the Corporation
may postpone the delivery of the certificates for such Common Stock until the
opening of such books, and they shall, in such case, be delivered forthwith
upon the opening thereof, or as soon as practicable thereafter.

         11.     Restrictions on Transferability of Warrants and Common Stock;
Compliance with Laws.  This Warrant and the Common Stock issued upon the
exercise hereof shall not be transferable except upon the conditions
hereinafter specified, which conditions are intended to insure compliance with
the provisions of the Securities Act of 1933 (or any similar federal statute at
the time in effect) in respect of the transfer of any Warrant or any such
Common Stock.

                 A.       Restrictive Legends.  Each Warrant shall bear on the
         face thereof a legend substantially in the form of the notice endorsed
         on the first page of this Warrant.  Each certificate for shares of
         Common Stock initially issued upon the exercise of any Warrant and
         each certificate for shares of Common Stock issued to a subsequent
         transferee of such certificate shall, unless otherwise permitted by
         the provisions of this paragraph, bear on the face thereof a legend
         reading substantially as follows:

                          "The shares represented by this certificate have not
                 been registered under the Securities Act of 1933, as amended,
                 and may not be offered, sold or transferred in the absence of
                 such registration or an exemption therefrom under said Act,
                 and are transferable only upon the conditions specified in the
                 Warrant pursuant to which such shares were issued."

                 B.       Removal of Legend.  In the event that a registration
         statement covering the Underlying Shares or the Restricted Stock shall
         become effective under the Securities Act or in the event that the
         Corporation shall receive an opinion of its counsel that, in the
         opinion of such counsel, such legend is not, or is no longer,
         necessary or required (including, but not limited to, because of the
         availability of the exemption afforded by Rule 144 of the General
         Rules and Regulations of the Commission), the Corporation shall, or
         shall instruct its transfer agents and registrars to, remove such
         legend from the certificates evidencing the Restricted Stock or issue
         new certificates without such legend in lieu thereof.  Upon the
         written request of the holder or holders of any Warrant or any
         Restricted Stock the Corporation covenants and agrees forthwith to
         request its counsel to render an opinion with respect to the matters
         covered by this paragraph and to bear all expenses in connection with
         the same.

         12.     Registration Rights.





                                 Page 18 of 23
<PAGE>   20
                 A.      Right to Piggyback.  Whenever securities of
         the Corporation are to be registered under the Securities Act, and the
         registration form to be used may be used for the registration of
         Registrable Shares (a "Piggyback Registration"), the Corporation will
         give prompt written notice (and in any event within three business
         days after its receipt of notice of any exercise of demand
         registration rights by holders of the Corporation's securities other
         than the Registrable Shares) to all Holders of Registrable Shares of
         its intention to effect such a registration and will include in such
         registration all Registrable Shares with respect to which the
         Corporation has received written requests for inclusion therein within
         21 days after the Corporation's notice has been given.

                 B.       Priority on Primary Registrations.   If a Piggyback
         Registration is an underwritten primary registration on behalf of the  
         Corporation, and the managing underwriters advise the Corporation in
         writing that in their opinion the number of securities requested to be
         included in such offering in the registration creates a substantial
         risk that the price per share of Common Stock will be reduced, the
         Corporation will include in such registration (i) first, the
         securities the Corporation proposes to sell, (ii) second, the
         Registrable Shares requested to be included in such registration which
         in the opinion of such underwriters can be sold in such offering
         without creating such a risk, pro rata among the Holders of such
         Registrable Shares on the basis of the number of Registrable Shares
         owned by such holders, with further successive pro rata allocations
         among the Holders of Registrable Shares if any such holder has
         requested the registration of less than all the Registrable Shares
         such Person is entitled to register, and (iii) third, other securities
         requested to be included in such registration.

                 C.       Priority on Secondary Registrations.   If a Piggyback
         Registration is an underwritten secondary registration on behalf of
         holders of the Corporation's securities, and the managing
         underwriters advise the Corporation in writing that in their opinion
         the inclusion of the number of securities requested to be included in
         such offering creates a substantial risk that the price per share of
         Common Stock will be reduced, the Corporation will include in such
         registration the Registrable Shares requested to be included in such
         registration and the securities requested to be included therein by
         the holders of the Corporation's securities requesting such
         registration (all such Registrable Shares and other securities
         requesting such registration being collectively referred to as the
         "Secondary Shares") which in the opinion of such underwriters can be
         sold in such offering without creating such a risk, pro rata among the
         holders of such Secondary Shares on the basis of the number of
         Secondary Shares owned or deemed to be owned by such holders, with
         further successive pro rata allocations among the holders of Secondary
         Shares if any such holder of Secondary Shares has requested the
         registration of less than all such Secondary Shares such Person is
         entitled to register.

                 D.       Other Registrations.   If the Corporation has
         previously filed a registration statement which includes Registrable
         Shares, and if such previous registration has not been withdrawn or 
         abandoned, the Corporation will not file or cause to be effected any 
         other registration of any of its equity securities or securities 
         convertible or exchangeable into or exercisable for its equity 
         securities under the Securities Act (except on Form S-4 or Form S-8),
         whether on its own behalf or at the request of any holder or holders 
         of such securities, 

                                 Page 19 of 23

<PAGE>   21
         until a period of 90 days has elapsed from the effective date of such
         previous registration.

                 E.       Limitations on Registrations.   The Corporation shall
         not register any of its securities for sale for its own account (other
         than securities issued to employees of the Corporation under an
         employee benefit plan or securities issued to effect a business
         combination pursuant to Rule 145 promulgated under the Securities Act
         and other than a registration on Form S-3) except as a firm commitment
         underwriting.

                 F.       Compliance with Rule 144 and Rule 144A.   At any time
         and from time to time after (a) the Corporation registers a class of
         securities under Section 12 of the Securities Exchange Act, or (b)
         the expiration of 90 days following the close of business on the
         earlier of such date as the Corporation commences to file reports under
         Section 13 or Section 15(d) of the Securities Exchange Act, then at the
         request of any holder who proposes to sell securities in compliance
         with Rule 144 promulgated by the Commission, the Corporation will (i)
         forthwith furnish to such holder a written statement of compliance with
         the filing requirements of the Commission as set forth in Rule 144 as
         such rule may be amended form time to time and (ii) make available to
         the public and such holders such information as will enable the Holders
         to make sales pursuant to Rule 144.  Unless the Corporation is subject
         to Section 13 or Section 15(d) of the Securities Exchange Act, the
         Corporation will provide to any Holder of Registrable Shares and to any
         prospective purchaser of Registrable Shares under Rule 144 promulgated
         by the Commission, the information described in Rule 144A(d)(4)
         promulgated by the Commission.

                 G.       Registration Expenses.

                 (1)      All expenses incident to the Corporation's
         performance of or compliance with this Agreement, including, but not
         limited to, all registration and filing fees, fees and expenses
         of compliance with federal, state and foreign securities laws, printing
         expenses, messenger and delivery expenses, and fees and disbursements
         of counsel for the Corporation and its independent certified public
         accountants, underwriters (excluding discounts and commissions
         attributable to the Registrable Shares included in such registration)
         and other Persons retained by the Corporation (all such expenses being
         herein called "Registration Expenses"), will be borne by the
         Corporation.  In addition, the Corporation will pay its internal
         expenses (including, but not limited to, all salaries and expenses of
         its officers and employees performing legal or accounting duties), the
         expense of any annual audit or quarterly review, the expense of any
         liability insurance obtained by the Corporation and the expenses and
         fees for listing the securities to be registered on each securities
         exchange.

                 (2)      In connection with any registration statement in
         which Registrable Shares are included, the Corporation will reimburse
         the Holders of Registrable Shares covered by such registration for
         the reasonable cost and expenses incurred by such holders in connection
         with such registration, including, but not limited to, reasonable fees
         and disbursements of one counsel chosen by the Holders of a majority of
         such Registrable Shares.





                                 Page 20 of 23
<PAGE>   22
                 H.       Holdback Agreements.  Each of the Holders of
         Registrable Shares agrees not to effect any public sale of equity
         securities of the Corporation, or any securities convertible into or
         exchangeable or exercisable for such securities, during the seven days
         prior to and the 90-day period beginning on the effective date of any
         underwritten Demand Registration (except as part of such underwritten
         registration), unless the underwriters managing the registered public
         offering otherwise agree.

         13.     Partial Exercise and Partial Assignment.  If this Warrant is
exercised in part only, the holder hereof shall be entitled to receive a new
Warrant covering the number of shares in respect of which this Warrant shall
not have been exercised as provided in Paragraph 2 hereof.  If this Warrant is
partially assigned, this Warrant shall be surrendered at the principal office
of the Corporation in Schaumburg, Illinois, and thereupon a new Warrant shall
be issued to the holder hereof covering the number of shares not assigned.  The
assignee of such partial assignment of this Warrant shall also be entitled to
receive a new Warrant covering the number of shares so assigned.

         14.     Warrant Denominations.  Warrants are issuable or transferable
in the denomination of 100 shares or any integral multiple thereof (as nearly
as may be practicable and subject to required adjustments hereunder), and the
Warrants of each denomination are interchangeable upon surrender thereof at the
office of the Corporation for Warrants of other denominations, but aggregating
the same number of shares as the Warrants so surrendered.  All Warrants will be
dated the same date as this Warrant.

         15.     Lost, Stolen, destroyed or Mutilated Warrants.  In case any
Warrant shall be mutilated, lost, stolen or destroyed, the Corporation may
issue a new Warrant of like date, tenor and denomination and deliver the same
in exchange and substitution for and upon surrender and cancellation of any
mutilated Warrant, or in lieu of any Warrant lost, stolen or destroyed, upon
receipt of evidence satisfactory to the Corporation of the loss, theft or
destruction of such Warrant, and upon receipt of indemnity satisfactory to the
Corporation.

         16.     Warrant Holder Not Stockholder.  This Warrant does not confer
upon the holder hereof any right to vote or to consent or to receive notice as
a stockholder of the Corporation, as such, in respect of any matters
whatsoever, or any other rights or liabilities as a stockholder, prior to the
exercise hereof as hereinbefore provided.

         17.     Severability.  Should any part of this Warrant for any reason
be declared invalid, such decision shall not affect the validity of any
remaining portion, which remaining portion shall remain in full force and
effect as if this Warrant had been executed with the invalid portion thereof
eliminated, and it is hereby declared the intention of the parties hereto that
they would have executed and accepted the remaining portion of this Warrant
without including therein any such part, parts or portion which may, for any
reason, be hereafter declared invalid.

         IN WITNESS WHEREOF, PRINCETON DENTAL MANAGEMENT CORPORATION has caused
this Warrant to be signed by its President or one of its Vice Presidents and

attested by its Secretary or one of its Assistant Secretaries and this Warrant
to be dated as of January 1, 1996.

                         AMENDMENT OF WARRANT AGREEMENT

         THIS FIRST AMENDMENT, made this 17th day of July, 1996 (this
"Amendment"), is made to the Stratum Warrant dated March 4, 1996 (the "Stratum
Warrant" or "Warrant Agreement") by and between PRINCETON DENTAL MANAGEMENT
CORPORATION, a Delaware corporation ("Princeton") and STRATUM MANAGEMENT, INC.

                                   RECITALS:

         A.  Princeton has issued the Stratum Warrant to Stratum giving
Stratum the right to purchase up to 600,000 shares of Princeton common stock.

         B.  Certain lenders of Princeton have required that Stratum forfeit
its rights to certain of the Warrants as a condition of a certain Letter
Agreement.

         NOW, THEREFORE, for the reasons stated above and for other good and
valuable consideration, the receipt and sufficiency of which are hereby
acknowledged, the Bank and the Borrower hereby agree as follows.

                                  AGREEMENTS:

         SECTION 1 Amendments to Stratum Warrant.  The Stratum Warrant shall be
amended by striking the term "600,000 shares" wherever it appears and
substituting in its place the term "388,000 shares."  Stratum acknowledges and
agrees that the Warrant shall remain in effect except that it shall only have
the right to purchase 388,000 shares upon the terms and conditions stated
therein.  Stratum agrees to execute a replacement Warrant Agreement and cancel
the existing Warrant Agreement upon the request of Princeton.

exchanges on which such security may at the time be listed, or, if there has
been no sale on any such exchange on any day, the average of the highest bid

the Options (a) if no adjustments have theretofore been made pursuant to the
provisions of Paragraph 4 hereof, the Original Number of Option Shares and (b)
if any one or more such adjustments have been so made, the amount to which the

terms of this Option, in each case reduced appropriately by the Number of
Option Shares theretofore purchased pursuant to the exercise of the Options.

         "Option Shares" shall mean shares of Common Stock purchased or
purchasable by the holder of this Option upon the exercise hereof.

         "Subsidiary" means any Person of which securities or other ownership
interests representing more than fifty percent (50%) of the ordinary voting
power are, at the time as of which any determination is being made, owned or
controlled by the Corporation or one or more Subsidiaries of the Corporation or

         "Underlying Shares" shall mean the shares of Common Stock issuable
upon exercise of any of the Options.

         2.      Accrual of Options; Exercise of Option.  This Option and all
rights and options hereunder shall expire at the close of business on March 20,
1999.  This Option and all options and rights hereunder shall be wholly void to
the extent that this Option is not exercised before it expires.

         3.      Reservation of Common Stock.  The Corporation covenants and
agrees that during the period within which the rights represented by this
Option may be exercised, the Corporation will at all times have authorized, and
in reserve, a sufficient number of shares of its Common Stock to provide for
the exercise of the rights represented by this Option.

         4.      Protection Against Dilution.  The Number of Option Shares
deliverable hereunder shall be adjusted as hereinafter set forth:

                 A.       Stock Dividends, Subdivisions and Combinations.  In
         case after the date hereof the Corporation shall:

                          (1)     take a record of the holders of its Common
                 Stock for the purpose of entitling them to receive a dividend
                 payable in, or other distribution of, Common Stock, or

                          (2)     subdivide its outstanding shares of Common
                 Stock into a larger number of shares of Common Stock, or

                          (3)     combine its outstanding shares of Common
                 Stock into a smaller number of shares of Common Stock,

         then the number of Option Shares shall be adjusted to that Number of
         Option Shares determined by multiplying the Number of Option Shares
         which could be purchased hereunder immediately prior to such event by
         a fraction (i) the numerator of which shall be the total number of
         outstanding shares of Common Stock of the Corporation immediately
         after such event, and (ii) the denominator of which shall be the total
         number of outstanding shares of Common Stock of the Corporation
         immediately prior to such event.

                 B.      Other Provisions, Applicable to Adjustments
         Under this Section.  The following provisions shall be
         applicable to the making of adjustments in the Number of
         Option Shares hereinbefore provided in this paragraph:




                                 Page 3 of 11
<PAGE>   4

                          (1)     Record Date.  If the Corporation takes a
                 record of the holders of Common Stock for the purpose of
                 entitling them (i) to receive a dividend or other distribution
                 payable in Common Stock, or (ii) to subscribe for or purchase
                 Common Stock, then for purposes of this paragraph such record
                 date will be deemed to be the date of the issue or sale of the
                 shares of Common Stock deemed to have been issued or sold upon
                 the declaration of such dividend or upon the making of such
                 other distribution or the date of the granting of such right
                 of subscription or purchase, as the case may be.  If
                 thereafter the Corporation shall have legally abandoned its
                 plan to make such dividend or distribution without having made
                 such dividend or distribution, then the number of shares of
                 Common Stock deemed to have been issued and outstanding shall
                 no longer be computed as set forth in Paragraph 4A above and
                 the Number of Option Shares shall forthwith be readjusted and
                 thereafter be the Number of Option Shares which it would have
                 been had the adjustment of the Number of Option Shares been
                 made upon the issuance of such stock dividend rather than the
                 taking of the record of holders with respect thereto.

                          (2)     Treasury Shares.  The number of shares of
                 Common Stock outstanding at any given time does not include
                 shares owned or held by or for the account of the Corporation
                 or any subsidiary, and the disposition of any shares so owned
                 or held will be considered an issue or sale of Common Stock.

                 C.       Adjustment of Purchase Price.  Whenever the Number of
         Option Shares hereunder shall be adjusted as set forth in this
         Paragraph 4, the Purchase Price shall be correspondingly adjusted by
         multiplying the Purchase Price then in effect by a fraction, (i) the
         numerator of which shall be the total number of outstanding shares of
         Common Stock of the Corporation prior to such adjustment, and (ii) the
         denominator of which shall be the total number of outstanding shares
         of Common Stock of the Corporation immediately after such adjustment.

                 D.       Notice of Adjustments.  Whenever the Number of Option
         Shares purchasable and the Purchase Price shall be required to be
         adjusted pursuant to this Paragraph 4, the Corporation shall promptly
         prepare a certificate signed by the President or a Vice President and
         by the Chief Financial Officer setting forth, in reasonable detail,
         the event requiring the adjustment, the amount of the adjustment, the
         method by which such adjustment was calculated (including a
         description of the basis on which the Board of Directors of the
         Corporation made any determination hereunder), and shall promptly
         cause  copies of such certificate to be mailed (by first class mail
         postage prepaid) to each of the holders of the Options.

        5.      Mergers, Consolidations, Sales.  In the case of any
consolidation or merger of the Corporation with another entity, or the sale of
all or substantially all of its assets to another entity, or any reorganization
or reclassification of the Common Stock or other equity securities of the
Corporation (except  a subdivision or combination of the Common Stock provision
for which is made in Paragraph 4A), then, as a condition of such consolidation,
merger, sale, reorganization or reclassification, lawful and adequate provision
shall be made 





                                 Page 4 of 11
<PAGE>   5
whereby the holders of the Options shall thereafter have the right to
receive upon the basis and upon the terms and conditions specified herein and
in lieu of the shares of Common Stock immediately theretofore purchasable
hereunder, such shares of stock, securities or assets as may (by virtue of such
consolidation, merger, sale, reorganization or reclassification) be issued or
payable with respect to or in exchange for a number  of outstanding shares of
Common Stock equal to the number of shares of Common Stock immediately
theretofore so purchasable hereunder had such consolidation, merger, sale,
reorganization or reclassification not taken place, and in any such case
appropriate provisions shall be made with respect to the rights and interests
of the holders of the Options to the end that the provisions hereof (including,
but not limited to, provisions for adjustment of the Number of Option Shares
and Purchase Price) shall thereafter be applicable as nearly as may be, in
relation to any shares of stock, securities or assets thereafter deliverable
upon exercise of this Option.  The Corporation shall not affect any such
consolidation, merger or sale, unless prior to or simultaneously with the
consummation thereof, the successor entity (if other than the Corporation)
resulting from such consolidation or merger or the entity purchasing such
assets shall assume by written instrument executed and mailed or delivered to
each holder of the Options, the obligation to deliver to such holder such
shares of stock, securities or assets as, in accordance with the foregoing
provisions, such holder may be entitled to receive.

         6.      Dissolution or Liquidation.  In the event of any proposed
distribution of the assets of the Corporation in dissolution or liquidation
(except under circumstances when the foregoing Paragraph 5 shall be applicable)
the Corporation shall mail notice thereof to the holders of the Options and
shall make no distribution to stockholders until the expiration of 30 days from
the date of mailing of the aforesaid notice and, in any such case, the holders
of the Options may exercise the conversion rights with respect to the Options
within 30 days from the date of mailing such notice and all rights herein
granted not so exercised within such 30 day period shall thereafter become null
and void.

         7.      Notice of Extraordinary Dividends.  If the Board of Directors
of the Corporation shall declare any dividend or other distribution on its
common Stock except out of earned surplus or by way of a stock dividend payable
on its Common Stock, the Corporation shall mail notice thereof to the holders
of the Options not less than 30 days prior to the record date fixed for
determining stockholders entitled to participate in such dividend or other
distribution or be entitled to any rights on account or as a result thereof
unless and to the extent that the Options are exercised prior to such record
date.

         8.      Fractional Shares.  Fractional shares shall not be issued upon
the exercise of this Option but in any case where the holder hereof would,
except for the provisions of this paragraph, be entitled under the terms hereof
to receive a fractional share upon the complete exercise of this Option, the
Corporation shall, upon the exercise of this Option for the largest
number of whole shares then called for, pay a sum in cash equal to the Market
Price of such fractional share.

         9.      Fully Paid Stock; Taxes. The Corporation covenants and agrees
that the shares of stock represented by each and every certificate for its
Common Stock to be delivered on 




                                 Page 5 of 11
<PAGE>   6
the exercise of the conversion rights herein provided for shall, at the
time of such delivery, be validly issued and outstanding and be fully paid and
nonassessable.  The Corporation further covenants and agrees that it will pay
when due and payable any and all federal and state taxes (other than Income
taxes) which may be payable in respect of the Options or any Common Stock or
certificates therefor upon the exercise of the conversion rights herein
provided for pursuant to the provisions hereof.

         10.     Closing of Transfer Books.  The right to exercise any Option
shall not be suspended during any period while the stock transfer books of the
Corporation for its Common Stock may be closed.  The Corporation shall not be
required, however, to deliver certificates of its Common Stock upon such
exercise while such books are duly closed for any purpose, but the Corporation
may postpone the delivery of the certificates for such Common Stock until the
opening of such books, and they shall, in such case, be delivered forthwith
upon the opening thereof, or as soon as practicable thereafter.

         11.     Restrictions on Transferability of Options and Common Stock;
Compliance with Laws.  This Option and the Common Stock issued upon the
exercise hereof shall not be transferable except upon the conditions
hereinafter specified, which conditions are intended to insure compliance with
the provisions of the Securities Act of 1933 (or any similar federal statute at
the time in effect) in respect of the transfer of any Option or any such Common
Stock.

                 A.       Restrictive Legends.  Each Option shall bear on the
         face thereof a legend substantially in the form of the notice endorsed
         on the first page of this Option.  Each certificate for shares of
         Common Stock initially issued upon the exercise of any Option and each
         certificate for shares of Common Stock issued to a subsequent
         transferee of such certificate shall, unless otherwise permitted by
         the provisions of this paragraph, bear on the face thereof a legend
         reading substantially as follows:

                          "The shares represented by this certificate have not
                 been registered under the Securities Act of 1933, as amended,
                 and may not be offered, sold or transferred in the absence of
                 such registration or an exemption therefrom under said Act,
                 and are transferable only upon the conditions specified in the
                 Option pursuant to which such shares were issued."

                 B.       Removal of Legend.  In the event that a registration
         statement covering the Underlying Shares or the Restricted
         Stock shall become effective under the Securities Act or in the event
         that the Corporation shall receive an opinion of its counsel that, in
         the opinion of such counsel, such legend is not, or is no longer,
         necessary or required (including, but not limited to, because of the
         availability of the exemption afforded by Rule 144 of the General
         Rules and Regulations of the Commission), the Corporation shall, or
         shall instruct its transfer agents and registrars to, remove such
         legend from the certificates evidencing the Restricted Stock or issue
         new certificates without such legend in lieu thereof.  Upon the
         written request of the holder or holders of any Option or any
         Restricted Stock the Corporation covenants and 




                                 Page 6 of 11
<PAGE>   7
         agrees forthwith to request its counsel to render an
         opinion with respect to the matters covered by this paragraph and to
         bear all expenses in connection with the same.

         12.     Registration Rights.

                 A.       Right to Piggyback.  Whenever securities of the
Corporation are to be registered under the Securities Act, and the registration
form to be used may be used for the registration of Registrable Shares (a
"Piggyback Registration"), the Corporation will give prompt written notice (and
in any event within three business days after its receipt of notice of any
exercise of demand registration rights by holders of the Corporation's
securities other than the Registrable Shares) to all Holders of Registrable
Shares of its intention to effect such a registration and will include in such
registration all Registrable Shares with respect to which the Corporation has
received written requests for inclusion therein within 21 days after the
Corporation's notice has been given.

                 B.       Priority on Primary Registrations.   If a Piggyback
Registration is an underwritten primary registration on behalf of the
Corporation, and the managing underwriters advise the Corporation in writing
that in their opinion the number of securities requested to be included in such
offering in the registration creates a substantial risk that the price per
share of Common Stock will be reduced, the Corporation will include in such
registration (i) first, the securities the Corporation proposes to sell, (ii)
second, the Registrable Shares requested to be included in such registration
which in the opinion of such underwriters can be sold in such offering without
creating such a risk, pro rata among the Holders of such Registrable Shares on
the basis of the number of Registrable Shares owned by such holders, with
further successive pro rata allocations among the Holders of Registrable Shares
if any such holder has requested the registration of less than all the
Registrable Shares such Person is entitled to register, and (iii) third, other
securities requested to be included in such registration.

                 C.       Priority on Secondary Registrations.   If a Piggyback
Registration is an underwritten secondary registration on behalf of holders of
the Corporation's securities, and the managing underwriters advise the
Corporation in writing that in their opinion the inclusion of the number of
securities requested to be included in such offering creates a substantial risk
that the price per share of Common Stock will be reduced, the Corporation will
include in such registration the Registrable Shares requested to be included in
such registration and the securities requested to be included therein by the
holders of the Corporation's securities requesting such registration (all such
Registrable Shares and other securities requesting such registration being
collectively referred to as the "Secondary Shares") which in the opinion of
such underwriters can be sold in such offering without creating such a risk,
pro rata among the holders of such Secondary Shares on the basis of the number
of Secondary Shares owned or deemed to be owned by such holders, with further
successive pro rata allocations among the holders of Secondary Shares if any
such holder of Secondary Shares has requested the registration of less than all
such Secondary Shares such Person is entitled to register.

                 D.       Other Registrations.   If the Corporation has
previously filed a registration statement which includes Registrable Shares,
and if such previous registration has not been withdrawn or abandoned, the
Corporation will not file or cause to be effected any other registration of any
of its equity securities or securities convertible or exchangeable into or
exercisable for its equity securities under the Securities Act (except on Form
S-4 or Form S-8), whether on its own behalf or at the request of any holder or
holders of such securities, until a period of 90 days has elapsed from the
effective date of such previous registration.

                 E.       Limitations on Registrations.   The Corporation shall
not register any of its securities for sale for its own account (other than
securities issued to employees of the Corporation under an employee benefit
plan or securities issued to effect a business combination pursuant to Rule 145
promulgated under the Securities Act and other than a registration on Form S-3)
except as a firm commitment underwriting.

                 F.       Compliance with Rule 144 and Rule 144A.   At any time
and from time to time after (a) the Corporation registers a class of securities
under Section 12 of the Securities Exchange Act, or (b) the expiration of 90
days following the close of business on the earlier of such date as the
Corporation commences to file reports under Section 13 or Section 15(d) of the
Securities Exchange Act, then at the request of any holder who proposes to sell
securities in compliance with Rule 144 promulgated by the Commission, the
Corporation will (i) forthwith furnish to such holder a written statement of
compliance with the filing requirements of the Commission as set forth in Rule
144 as such rule may be amended form time to time and (ii) make available to
the public and such holders such information as will enable the Holders to make
sales pursuant to Rule 144.  Unless the Corporation is subject to Section 13 or
Section 15(d) of the Securities Exchange Act, the Corporation will provide to
any Holder of Registrable Shares and to any prospective purchaser of
Registrable Shares under Rule 144 promulgated by the Commission, the
information described in Rule 144A(d)(4) promulgated by the Commission.

                 G.       Registration Expenses.

                 (1)      All expenses incident to the Corporation's
performance of or compliance with this Agreement, including, but not limited
to, all registration and filing fees, fees and expenses of compliance with
federal, state and foreign securities laws, printing expenses, messenger and
delivery expenses, and fees and disbursements of counsel for the Corporation
and its independent certified public accountants, underwriters (excluding
discounts and commissions attributable to the Registrable Shares included in
such registration) and other Persons retained by the Corporation (all such
expenses being herein called "Registration Expenses"), will be borne by the
Corporation.  In addition, the Corporation will pay its internal expenses
(including, but not limited to, all salaries and expenses of its officers and
employees performing legal or accounting duties), the expense of any annual
audit or quarterly review, the expense of any liability insurance obtained by
the Corporation and the expenses and fees for listing the securities to be
registered on each securities exchange.

<PAGE>   9

                 (2)      In connection with any registration statement in
which Registrable Shares are included, the Corporation will reimburse the
Holders of Registrable Shares covered by such registration for the reasonable
cost and expenses incurred by such holders in connection with such
registration, including, but not limited to, reasonable fees and disbursements
of one counsel chosen by the Holders of a majority of such Registrable Shares.

                 H.       Holdback Agreements.  Each of the Holders of
Registrable Shares agrees not to effect any public sale of equity securities of
the Corporation, or any securities convertible into or exchangeable or
exercisable for such securities, during the seven days prior to and the 90-day
period beginning on the effective date of any underwritten Demand Registration
(except as part of such underwritten registration), unless the underwriters
managing the registered public offering otherwise agree.

         13.     Partial Exercise and Partial Assignment.  If this Option is
exercised in part only, the holder hereof shall be entitled to receive a new
Option covering the number of shares in respect of which this Option shall not
have been exercised as provided in Paragraph 2 hereof.

         14.     Option Denominations.  Options are issuable or transferable in
the denomination of 100 shares or any integral multiple thereof (as nearly as
may be practicable and subject to required adjustments hereunder), and the
Options of each denomination are interchangeable upon surrender thereof at the
office of the Corporation for Options of other denominations, but aggregating
the same number of shares as the Options so surrendered.  All Options will be
dated the same date as this Option.

         15.     Lost, Stolen, destroyed or Mutilated Options.  In case any
Option shall be mutilated, lost, stolen or destroyed, the Corporation may issue
a new Option of like date, tenor and denomination and deliver the same in
exchange and substitution for and upon surrender and cancellation of any
mutilated Option, or in lieu of any Option lost, stolen or destroyed, upon
receipt of evidence satisfactory to the Corporation of the loss, theft or
destruction of such Option, and upon receipt of indemnity satisfactory to the
Corporation.

         16.     Option Holder Not Stockholder.  This Option does not confer
upon the holder hereof any right to vote or to consent or to receive notice as
a stockholder of the Corporation, as such, in respect of any matters
whatsoever, or any other rights or liabilities as a stockholder, prior to the
exercise hereof as hereinbefore provided.

         17.     Severability.  Should any part of this Option for any reason
be declared invalid, such decision shall not affect the validity of any
remaining portion, which remaining portion shall remain in full force and
effect as if this Option had been executed with the invalid portion thereof
eliminated, and it is hereby declared the intention of the parties hereto that
they would have executed and accepted the remaining portion of this Option
without including therein any such part, parts or portion which may, for any
reason, be hereafter declared invalid.

in reserve, a sufficient number of shares of its Common Stock to provide for

deliverable hereunder shall be adjusted as hereinafter set forth:

                 A.       Stock Dividends, Subdivisions and Combinations.  In
         case after the date hereof the Corporation shall:

                          (1)     take a record of the holders of its Common
                 Stock for the purpose of entitling them to receive a dividend
                 payable in, or other distribution of, Common Stock, or

                          (2)     subdivide its outstanding shares of Common
                 Stock into a larger number of shares of Common Stock, or

                          (3)     combine its outstanding shares of Common
                 Stock into a smaller number of shares of Common Stock,

         then the number of Option Shares shall be adjusted to that Number of
         Option Shares determined by multiplying the Number of Option Shares
         which could be purchased hereunder immediately prior to such event by
         a fraction (i) the numerator of which shall be the total number of
         outstanding shares of Common Stock of the Corporation immediately
         after such event, and (ii) the denominator of which shall be the total
         number of outstanding shares of Common Stock of the Corporation
         immediately prior to such event.





                                 Page 3 of 11
<PAGE>   4
                 B.       Other Provisions, Applicable to Adjustments Under this
         Section.  The following provisions shall be applicable to the making
         of adjustments in the Number of Option Shares hereinbefore provided in
         this paragraph:

                          (1)     Record Date.  If the Corporation takes a
                 record of the holders of common Stock for the purpose of
                 entitling them (i) to receive a dividend or other distribution
                 payable in Common Stock, or (ii) to subscribe for or purchase
                 Common Stock, then for purposes of this paragraph such record
                 date will be deemed to be the date of the issue or sale of the
                 shares of Common Stock deemed to have been issued or sold upon
                 the declaration of such dividend or upon the making of such
                 other distribution or the date of the granting of such right
                 of subscription or purchase, as the case may be.  If
                 thereafter the Corporation shall have legally abandoned its
                 plan to make such dividend or distribution without having made
                 such dividend or distribution, then the number of shares of
                 Common Stock deemed to have been issued and outstanding shall
                 no longer be computed as set forth in Paragraph 4A above and
                 the Number of Option Shares shall forthwith be readjusted and
                 thereafter be the Number of Option Shares which it would have
                 been had the adjustment of the Number of Option Shares been
                 made upon the issuance of such stock dividend rather than the
                 taking of the record of holders with respect thereto.

                          (2)     Treasury Shares.  The number of shares of
                 Common Stock outstanding at any given time does not include
                 shares owned or held by or for the account of the Corporation
                 or any subsidiary, and the disposition of any shares so owned
                 or held will be considered an issue or sale of Common Stock.

                 C.       Adjustment of Purchase Price.  Whenever the Number of
         Option Shares hereunder shall be adjusted as set forth in this
         Paragraph 4, the Purchase Price shall be correspondingly adjusted by
         multiplying the Purchase Price then in effect by a fraction, (i) the
         numerator of which shall be the total number of outstanding shares of
         Common Stock of the Corporation prior to such adjustment, and (ii) the
         denominator of which shall be the total number of outstanding shares
         of Common Stock of the Corporation immediately after such adjustment.

                 D.       Notice of Adjustments.  Whenever the Number of Option
         Shares purchasable and the Purchase Price shall be required to be
         adjusted pursuant to this Paragraph 4, the Corporation shall promptly
         prepare a certificate signed by the President or a Vice President and
         by the Chief Financial Officer setting forth, in reasonable detail,
         the event requiring the adjustment, the amount of the adjustment, the
         method by which such adjustment was calculated (including a
         description of the basis on which the Board of Directors of the
         Corporation made any determination hereunder), and shall promptly
         cause copies of such certificate to be mailed (by first class mail
         postage prepaid) to each of the holders of the Options.

         5.      Mergers, Consolidations, Sales.  In the case of any
consolidation or merger of the Corporation with another entity, or the sale of
all or substantially all of its assets to





                                 Page 4 of 11
<PAGE>   5
another entity, or any reorganization or reclassification of the
Common Stock or other equity securities of the Corporation (except  a
subdivision or combination of the Common Stock provision for which is
made in Paragraph 4A), then, as a condition of such consolidation,
merger, sale, reorganization or reclassification, lawful and adequate
provision shall be made whereby the holders of the Options shall
thereafter have the right to receive upon the basis and upon the terms
and conditions specified herein and in lieu of the shares of Common
Stock immediately theretofore purchasable hereunder, such shares of
stock, securities or assets as may (by virtue of such consolidation,
merger, sale, reorganization or reclassification) be issued or payable
with respect to or in exchange for a number  of outstanding shares of
Common Stock equal to the number of shares of Common Stock immediately
theretofore so purchasable hereunder had such consolidation, merger,
sale, reorganization or reclassification not taken place, and in any
such case appropriate provisions shall be made with respect to the
rights and interests of the holders of the Options to the end that the
provisions hereof (including, but not limited to, provisions for
adjustment of the Number of Option Shares and Purchase Price) shall
thereafter be applicable as nearly as may be, in relation to any
shares of stock, securities or assets thereafter deliverable upon
exercise of this Option.  The Corporation shall not affect any such
consolidation, merger or sale, unless prior to or simultaneously with
the consummation thereof, the successor entity (if other than the
Corporation) resulting from such consolidation or merger or the entity
purchasing such assets shall assume by written instrument executed and
mailed or delivered to each holder of the Options, the obligation to
deliver to such holder such shares of stock, securities or assets as,
in accordance with the foregoing provisions, such holder may be
entitled to receive.

         6.      Dissolution or Liquidation.  In the event of any proposed
distribution of the assets of the Corporation in dissolution or liquidation
(except under circumstances when the foregoing Paragraph 5 shall be applicable)
the Corporation shall mail notice thereof to the holders of the Options and
shall make no distribution to stockholders until the expiration of 30 days from
the date of mailing of the aforesaid notice and, in any such case, the holders
of the Options may exercise the conversion rights with respect to the Options
within 30 days from the date of mailing such notice and all rights herein
granted not so exercised within such 30 day period shall thereafter become null
and void.

         7.      Notice of Extraordinary Dividends.  If the Board of Directors
of the Corporation shall declare any dividend or other distribution on its
common Stock except out of earned surplus or by way of a stock dividend payable
on its Common Stock, the Corporation shall mail notice thereof to the holders
of the Options not less than 30 days prior to the record date fixed for
determining stockholders entitled to participate in such dividend or other
distribution or be entitled to any rights on account or as a result thereof
unless and to the extent that the Options are exercised prior to such record
date.

         8.      Fractional Shares.  Fractional shares shall not be issued upon
the exercise of this Option but in any case where the holder hereof would,
except for the provisions of this paragraph, be entitled under the terms hereof
to receive a fractional share upon the complete exercise of this Option, the
Corporation shall, upon the exercise of this Option for the largest





                                 Page 5 of 11
<PAGE>   6
number of whole shares then called for, pay a sum in cash equal to the Market
Price of such fractional share.

         9.      Fully Paid Stock; Taxes. The Corporation covenants and agrees
that the shares of stock represented by each and every certificate for its
Common Stock to be delivered on the exercise of the conversion rights herein
provided for shall, at the time of such delivery, be validly issued and
outstanding and be fully paid and nonassessable.  The Corporation further
covenants and agrees that it will pay when due and payable any and all federal
and state taxes (other than Income taxes) which may be payable in respect of
the Options or any Common Stock or certificates therefor upon the exercise of
the conversion rights herein provided for pursuant to the provisions hereof.

         10.     Closing of Transfer Books.  The right to exercise any Option
shall not be suspended during any period while the stock transfer books of the
Corporation for its Common Stock may be closed.  The Corporation shall not be
required, however, to deliver certificates of its Common Stock upon such
exercise while such books are duly closed for any purpose, but the Corporation
may postpone the delivery of the certificates for such Common Stock until the
opening of such books, and they shall, in such case, be delivered forthwith
upon the opening thereof, or as soon as practicable thereafter.

         11.     Restrictions on Transferability of Options and Common Stock;
Compliance with Laws.  This Option and the Common Stock issued upon the
exercise hereof shall not be transferable except upon the conditions
hereinafter specified, which conditions are intended to insure compliance with
the provisions of the Securities Act of 1933 (or any similar federal statute at
the time in effect) in respect of the transfer of any Option or any such Common
Stock.

                 A.       Restrictive Legends.  Each Option shall bear on the
         face thereof a legend substantially in the form of the notice endorsed
         on the first page of this Option.  Each certificate for shares of
         Common Stock initially issued upon the exercise of any Option and each
         certificate for shares of Common Stock issued to a subsequent
         transferee of such certificate shall, unless otherwise permitted by
         the provisions of this paragraph, bear on the face thereof a legend
         reading substantially as follows:

                          "The shares represented by this certificate have not
                 been registered under the Securities Act of 1933, as amended,
                 and may not be offered, sold or transferred in the absence of
                 such registration or an exemption therefrom under said Act,
                 and are transferable only upon the conditions specified in the
                 Option pursuant to which such shares were issued."

                 B.       Removal of Legend.  In the event that a registration
         statement covering the Underlying Shares or the Restricted Stock shall
         become effective under the Securities Act or in the event that the
         Corporation shall receive an opinion of its counsel that, in the
         opinion of such counsel, such legend is not, or is no longer,
         necessary or required (including, but not limited to, because of the
         availability of the





                                 Page 6 of 11
<PAGE>   7
exemption afforded by Rule 144 of the General Rules and Regulations of
the Commission), the Corporation shall, or shall instruct its transfer
agents and registrars to, remove such legend from the certificates
evidencing the Restricted Stock or issue new certificates without such
legend in lieu thereof.  Upon the written request of the holder or
holders of any Option or any Restricted Stock the Corporation
covenants and agrees forthwith to request its counsel to render an
opinion with respect to the matters covered by this paragraph and to
bear all expenses in connection with the same.

         12.     Registration Rights.

                 A.       Right to Piggyback.  Whenever securities of the
Corporation are to be registered under the Securities Act, and the registration
form to be used may be used for the registration of Registrable Shares (a
"Piggyback Registration"), the Corporation will give prompt written notice (and
in any event within three business days after its receipt of notice of any
exercise of demand registration rights by holders of the Corporation's
securities other than the Registrable Shares) to all Holders of Registrable
Shares of its intention to effect such a registration and will include in such
registration all Registrable Shares with respect to which the Corporation has
received written requests for inclusion therein within 21 days after the
Corporation's notice has been given.

                 B.       Priority on Primary Registrations.   If a Piggyback
Registration is an underwritten primary registration on behalf of the
Corporation, and the managing underwriters advise the Corporation in writing
that in their opinion the number of securities requested to be included in such
offering in the registration creates a substantial risk that the price per
share of Common Stock will be reduced, the Corporation will include in such
registration (i) first, the securities the Corporation proposes to sell, (ii)
second, the Registrable Shares requested to be included in such registration
which in the opinion of such underwriters can be sold in such offering without
creating such a risk, pro rata among the Holders of such Registrable Shares on
the basis of the number of Registrable Shares owned by such holders, with
further successive pro rata allocations among the Holders of Registrable Shares
if any such holder has requested the registration of less than all the
Registrable Shares such Person is entitled to register, and (iii) third, other
securities requested to be included in such registration.

                 C.       Priority on Secondary Registrations.   If a Piggyback
Registration is an underwritten secondary registration on behalf of holders of
the Corporation's securities, and the managing underwriters advise the
Corporation in writing that in their opinion the inclusion of the number of
securities requested to be included in such offering creates a substantial risk
that the price per share of Common Stock will be reduced, the Corporation will
include in such registration the Registrable Shares requested to be included in
such registration and the securities requested to be included therein by the
holders of the Corporation's securities requesting such registration (all such
Registrable Shares and other securities requesting such registration being
collectively referred to as the "Secondary Shares") which in the opinion of
such underwriters can be sold in such offering without creating such a risk,
pro rata among the holders of such Secondary Shares on the basis of the number
of Secondary Shares owned or deemed to be owned by such holders, with further
successive pro rata





                                 Page 7 of 11
<PAGE>   8
allocations among the holders of Secondary Shares if any such holder of
Secondary Shares has requested the registration of less than all such Secondary
Shares such Person is entitled to register.

                 D.       Other Registrations.   If the Corporation has
previously filed a registration statement which includes Registrable Shares,
and if such previous registration has not been withdrawn or abandoned, the
Corporation will not file or cause to be effected any other registration of any
of its equity securities or securities convertible or exchangeable into or
exercisable for its equity securities under the Securities Act (except on Form
S-4 or Form S-8), whether on its own behalf or at the request of any holder or
holders of such securities, until a period of 90 days has elapsed from the
effective date of such previous registration.

                 E.       Limitations on Registrations.   The Corporation shall
not register any of its securities for sale for its own account (other than
securities issued to employees of the Corporation under an employee benefit
plan or securities issued to effect a business combination pursuant to Rule 145
promulgated under the Securities Act and other than a registration on Form S-3)
except as a firm commitment underwriting.

                 F.       Compliance with Rule 144 and Rule 144A.   At any time
and from time to time after (a) the Corporation registers a class of securities
under Section 12 of the Securities Exchange Act, or (b) the expiration of 90
days following the close of business on the earlier of such date as the
Corporation commences to file reports under Section 13 or Section 15(d) of the
Securities Exchange Act, then at the request of any holder who proposes to sell
securities in compliance with Rule 144 promulgated by the Commission, the
Corporation will (i) forthwith furnish to such holder a written statement of
compliance with the filing requirements of the Commission as set forth in Rule
144 as such rule may be amended form time to time and (ii) make available to
the public and such holders such information as will enable the Holders to make
sales pursuant to Rule 144.  Unless the Corporation is subject to Section 13 or
Section 15(d) of the Securities Exchange Act, the Corporation will provide to
any Holder of Registrable Shares and to any prospective purchaser of
Registrable Shares under Rule 144 promulgated by the Commission, the
information described in Rule 144A(d)(4) promulgated by the Commission.

                 G.       Registration Expenses.

                 (1)      All expenses incident to the Corporation's
performance of or compliance with this Agreement, including, but not limited
to, all registration and filing fees, fees and expenses of compliance with
federal, state and foreign securities laws, printing expenses, messenger and
delivery expenses, and fees and disbursements of counsel for the Corporation
and its independent certified public accountants, underwriters (excluding
discounts and commissions attributable to the Registrable Shares included in
such registration) and other Persons retained by the Corporation (all such
expenses being herein called "Registration Expenses"), will be borne by the
Corporation.  In addition, the Corporation will pay its internal expenses
(including, but not limited to, all salaries and expenses of its officers and
employees performing legal or accounting duties), the expense of any annual
audit or quarterly review, the expense of any liability insurance obtained by
the





                                 Page 8 of 11
<PAGE>   9
Corporation and the expenses and fees for listing the securities to be
registered on each securities exchange.

                 (2)      In connection with any registration statement in
which Registrable Shares are included, the Corporation will reimburse the
Holders of Registrable Shares covered by such registration for the reasonable
cost and expenses incurred by such holders in connection with such
registration, including, but not limited to, reasonable fees and disbursements
of one counsel chosen by the Holders of a majority of such Registrable Shares.

                 H.       Holdback Agreements.  Each of the Holders of
Registrable Shares agrees not to effect any public sale of equity securities of
the Corporation, or any securities convertible into or exchangeable or
exercisable for such securities, during the seven days prior to and the 90-day
period beginning on the effective date of any underwritten Demand Registration
(except as part of such underwritten registration), unless the underwriters
managing the registered public offering otherwise agree.

         13.     Partial Exercise and Partial Assignment.  If this Option is
exercised in part only, the holder hereof shall be entitled to receive a new
Option covering the number of shares in respect of which this Option shall not
have been exercised as provided in Paragraph 2 hereof.

         14.     Option Denominations.  Options are issuable or transferable in
the denomination of 100 shares or any integral multiple thereof (as nearly as
may be practicable and subject to required adjustments hereunder), and the
Options of each denomination are interchangeable upon surrender thereof at the
office of the Corporation for Options of other denominations, but aggregating
the same number of shares as the Options so surrendered.  All Options will be
dated the same date as this Option.

         15.     Lost, Stolen, destroyed or Mutilated Options.  In case any
Option shall be mutilated, lost, stolen or destroyed, the Corporation may issue
a new Option of like date, tenor and denomination and deliver the same in
exchange and substitution for and upon surrender and cancellation of any
mutilated Option, or in lieu of any Option lost, stolen or destroyed, upon
receipt of evidence satisfactory to the Corporation of the loss, theft or
destruction of such Option, and upon receipt of indemnity satisfactory to the
Corporation.

         16.     Option Holder Not Stockholder.  This Option does not confer
upon the holder hereof any right to vote or to consent or to receive notice as
a stockholder of the Corporation, as such, in respect of any matters
whatsoever, or any other rights or liabilities as a stockholder, prior to the
exercise hereof as hereinbefore provided.

         17.     Severability.  Should any part of this Option for any reason
be declared invalid, such decision shall not affect the validity of any
remaining portion, which remaining portion shall remain in full force and
effect as if this Option had been executed with the invalid portion thereof
eliminated, and it is hereby declared the intention of the parties hereto that
they would





                                 Page 9 of 11
<PAGE>   10
have executed and accepted the remaining portion of this Option without
including therein any such part, parts or portion which may, for any reason, be
hereafter declared invalid.

         IN WITNESS WHEREOF, PRINCETON DENTAL MANAGEMENT CORPORATION has caused
this Option to be signed by its President or one of its Vice Presidents and
this Option to be dated as of March 21, 1996.

         pursuant to an offer made under this Section 2.3.1 upon less than 30
         Business Days' prior notice by the Company, the Company shall pay the
         Purchasers an aggregate fee equal to 2.5% of the Purchase Price times
         the number of Preferred Shares purchased, which fee may be deducted
         from the Purchase Price.  The offer to sell Preferred Shares must be
         made in writing by an Authorized Representative pursuant to the notice
         provisions of Section 10.2 hereof, and shall specify the number of
         Preferred Shares offered and the date on which such shares are to be
         sold.  Any such offer which the Purchasers believe to come from an
         Authorized Representative shall be irrevocable and binding on the
         Company.  Before 10:00 a.m. Chicago time on the date the Preferred
         Shares are to be sold, the Company shall deliver to Purchasers a duly

certificate are effectively registered under the Securities Act of 1933, as
amended ("Securities Act") or (b) the holder of Preferred Shares delivers to

         "The securities represented by this certificate have not been
         registered under the Securities Act of 1933, as amended, and thus may
         not be transferred unless so registered or unless an exemption from
         registration is available."

         as such debts become due, shall admit in writing its inability to pay
         its debts generally, or shall make a general assignment for the

         either such proceeding shall remain undismissed or unstayed for a 
         period of 30 days or any of the actions sought in such proceeding 
         (including, without limitation, the entry of an order for relief 
         against it or the appointment of a receiver, trustee, custodian or 
         other similar official for it or for any substantial part of its 
         property) shall occur; or the Company shall take any action to 
         authorize any of the actions set forth above in this Section 7.1.7; or

              13.1.8      any Person entitled to take the actions described in
         this Section 7.1.8, after the occurrence of any default or event of
         default under any agreement, mortgage, indenture or instrument
         evidencing any Indebtedness of the Company which is outstanding in a
         principal amount of at least $10,000.00 in the aggregate, shall notify
         the Company of the intended sale or disposition of any assets of the
         Company that have been pledged to or for the benefit of such Person to
         secure such Indebtedness or shall commence proceedings or take any
         action (including by way of set-off) to retain in satisfaction of any
         such Indebtedness, or to collect on, seize, dispose of, or apply, any
         assets of the Company (including funds on deposit or held pursuant to
         lock box and other similar arrangements), pursuant to the terms of any
         agreement or instrument evidencing any such Indebtedness or in

         decrees against the Company, any Subsidiary or any guarantor of any of
         the Liabilities involving an aggregate liability of $25,000.00 or more
         (other than a money judgment covered by insurance, but only if the
         insurer has admitted, in writing, liability with respect to such
         judgment); or

              13.1.10     if any of the present executive officers of the
         Company are no longer personally and actively involved in the
         management and supervision of the Company or any of its Subsidiaries,
         at least substantially to the same extent as of the date hereof,
         except that, if any of them is no longer so involved due to his death
         or disability, such event shall not be an Event of Default if he is
         replaced within 45 days by another person acceptable to Lender in its
         Sole and Exclusive Discretion (which must be evidenced in writing by
         Lender).

         Notwithstanding the foregoing, the mere failure to pay interest under
the Convertible Secured Notes which is due in June 1996 or September 1996 or
the mere failure to pay dividends on the

Preferred Shares which is due on june 30, 1996 or September 30, 1996 shall not
be an Event of Default for any purpose hereunder, except that (1) such failure
to pay in September 1996 shall trigger interest at the Default Rate under the
Convertible Debt Agreement and dividents at the Default Rate under the 
Certificate of Designation, and (2) interest which is unpaid in June 1996 shall
be added to principal.

         13.2    Remedies.  If an Event of Default (other than an Event of
Default specified in Section 7.1.7) occurs and is continuing, Lender may, by
notice to the Company (the "Default Notice"), demand immediate redemption of
the outstanding Preferred Shares.  If an Event of Default specified in Section
7.1.7 occurs, the Company shall be immediately obligated to redeem the
outstanding Preferred Shares ipso facto and without any demand or other action
on the part of Lender.  The redemption price to be paid to the Purchasers for
such Preferred Shares shall be the aggregate Liquidation Value (as defined in
the Certificate of Designation) thereof, plus all unpaid, accumulated dividends
thereon.  Lender by notice to the Company may rescind any demand for redemption
and its consequences if the rescission would not conflict with any judgment or
decree and if all existing Events of Default hereunder have been cured or
waived except nonpayment of the amounts that has become due solely because of
the demand for redemption.

                                   THE AGENT


         15.1    Appointment.  Purchasers may appoint an Agent to act as escrow
agent hereunder and under the Certification of Designation by written notice to
the Company.  In the event of such appointment, the Agent shall be authorized
to take such action on behalf of Purchasers and the Company under the
provisions of this Agreement and the Certificate of Designation, the Related
Documents and any other instruments and agreements referred to herein or
therein and to exercise such powers and to perform such duties hereunder and
thereunder as are specifically delegated to or required of the Agent by the
terms hereof and thereof and such other powers as are reasonably incidental
thereto.  The Agent may perform any of its duties hereunder by or through its
officers, directors, agents or employees.

         15.2    Nature of Duties.  The Agent shall not have any duties or
responsibilities except those expressly set forth in this Agreement.  Neither
the Agent nor any of its officers, directors, agents or employees shall be
liable for any action taken or omitted by it or them hereunder or under any
Related Document or in connection herewith or therewith, unless caused by its
or their gross negligence or willful misconduct.  The duties of the Agent shall
be mechanical and administrative in nature; the Agent shall not have by reason
of this Agreement or any Related Document a fiduciary relationship in respect
of the Purchasers or the Company and nothing in this Agreement or any Related
Document, expressed or implied, is intended to or shall be so construed as to
impose upon the Agent any obligations in respect of this Agreement or any
Related Document except as expressly set forth herein.

         15.3    Lack of Reliance on the Agent.  In acting as Agent hereunder,
the Agent shall not be responsible to the Purchasers or the Company for any
recitals, statements, information, representations or warranties herein or in
any document, certificate or other writing delivered in connection herewith or
for the execution, effectiveness, genuineness, validity, enforceability,
perfection, collectibility, priority or sufficiency of this Agreement or any
Related Document or the financial condition of the Company or any of its
Subsidiaries or be required to make any inquiry concerning either the
performance or observance of any of the terms, provisions or conditions of this
Agreement or any Related Document, or the financial condition of the Company or
any of its Subsidiaries or the existence or possible existence of any Default
or Event of Default.

         15.4    Certain Rights of the Agent.  The Agent shall act only in
accordance with (a) the terms of this Agreement, (b) the written instructions
executed by both the Company and the Purchasers, or (c) an order of a court
which is no longer subject to appeal and which Agent is advised by counsel is
binding upon it.  If the Agent shall request instructions from the Purchasers
and the Company with respect to any act or action (including failure to act) in
connection with this Agreement or any Related Document which is not expressly
provided for herein, the Agent shall be entitled to refrain from such act or
taking such action unless and until the Agent shall have received instructions
from the Purchasers, the Company and the Agent shall not incur any liability to
any Person by reason of so refraining.  Without limiting the foregoing, neither
the Purchasers nor the Company shall have any right of action whatsoever
against the Agent as a result of the Agent acting or refraining from acting
hereunder or under any Related Document in accordance with the instructions of
the Purchasers and the Company.

<PAGE>   29
         15.5    Reliance.  The Agent shall be entitled to rely, and shall be
fully protected in relying, upon any note, writing, resolution, notice,
statement, certificate, telex, telecopier message, cablegram, radiogram, order
or other document or telephone message signed, sent or made by any Person that
the Agent believed to be the proper Person and, with respect to all legal
matters pertaining to this Agreement and any Related Document and its duties
hereunder and thereunder, upon advice of counsel selected by it in good faith.

         15.6    Indemnification.  The Company will reimburse and indemnify the
Agent for and against any and all liabilities, obligations, losses, damages,
penalties, actions, judgments, suits, costs, expenses or disbursements of any
kind or nature whatsoever which may be imposed on, incurred by or asserted
against the Agent in performing its duties hereunder (except to the extent
based upon acts or omissions constituting gross negligence or willful
misconduct in the performance of such duties) in his capacity as Agent or under
any Related Document, in any way relating to or arising out of this Agreement
or any Related Document.

         15.7    Holders.  The Agent may deem and treat the holders of any
Preferred Shares as the owner thereof for all purposes hereof unless and until
a written notice of the assignment, transfer or endorsement thereof, as the
case may be, shall have been filed with the Agent.  Any request, authority or
consent of any Person or entity who, at the time of making such request or
giving such authority or consent is the holder of any Preferred Shares shall be
conclusive and binding on any subsequent holder, transferee, assignee or
indorsee, as the case may be, of such Preferred Share or of any Preferred
Shares issued in exchange therefor.

         15.8    Resignation.

                 (a)      The Agent may resign from the performance of all its
         functions and duties hereunder and/or under the Related Documents at
         any time by giving 15 Business Days' prior written notice to the
         Company and the Purchasers.  Each such resignation shall take effect
         upon the expiration of such 15-day period, provided that the
         resignation of the last remaining Agent shall take effect upon the
         appointment of a successor Agent, pursuant to clauses (b) and (c)
         below or as otherwise provided below.

                 (b)      Upon any such notice of resignation of the last
         remaining Agent, the Purchasers shall appoint a successor Agent.

                 (c)      Following any notice of resignation by any Agent, if
         a successor Agent shall not have been so appointed within said 15
         Business Days, such Agent shall then appoint a successor Agent who
         shall serve as Agent hereunder or thereunder until such time, if any,
         as the Purchasers appoint a successor Agent as provided above.

                 (d)      If no successor Agent has been appointed pursuant to
         clause (b) or (c) above by the 29th Business Day after the date such
         notice of resignation was given by the Agent, Agent's resignation
         shall become effective and the Purchasers shall thereafter perform all
         the duties of the Agent hereunder and/or under any Related Document
         until such time, if any, as the Purchasers appoint a successor Agent 
         as provided above.

                                 MISCELLANEOUS

         16.1    Amendments, Etc.  No amendment or waiver of any provision of

         16.3    No Waiver; Remedies.  No failure on the part of Purchasers to
exercise, and no delay in exercising, any right hereunder or under the Related
Documents shall operate as a waiver thereof; nor shall any single or partial

or the exercise of any other right.  The remedies herein provided are
cumulative and not exclusive of any remedies provided by law.

         16.4    Costs and Expenses; Indemnity.

              16.4.1        Company shall pay on demand (i) all reasonable
         costs and expenses of Purchasers in connection with the preparation,
         execution, delivery, administration, modification and amendment of
         this Agreement and the Related Documents, including, without
         limitation, the fees and out-of-pocket expenses of counsel for
         Purchasers with respect thereto and other legal counsel advising any
         successors or assigns of Purchasers as to their respective rights and
         responsibilities under this Agreement, and due diligence,
         transportation, lodging, meals, computer, duplication, appraisal,
         audit, insurance, consultant, search and filing fees, costs and
         expenses of Purchasers, and (ii) all reasonable costs and expenses, if
         any, of Purchasers and any Assignees (including, without limitation,
         counsel fees and expenses), in connection with the enforcement
         (whether through negotiations, legal proceedings or otherwise) of
         their respective rights under this Agreement and the Related Documents
         or as shareholders of the Company.

              16.4.2        Company shall idemnify and hold harmless Purchasers
         and any Assignees and their respective Affiliates (each such Person 
         being an "Indemnified Party") from and against any and all losses, 
         claims, damages, liabilities and expenses (including, without 
         limitation, fees and



                                Page 30 of 37
<PAGE>   31
         disbursements of counsel and out of pocket expenses of Purchasers and
         their agents), which may be incurred by or asserted or awarded against
         any Indemnified Party, in each case in connection with, relating to or
         arising out of or by reason of, or in connection with the preparation 
         for or defense of, joint or several, any investigation, inquiry,  
         litigation or proceeding (i) relating to or arising out of the 
         transactions contemplated herein or the execution, delivery, 
         enforcement and performance of this Agreement or the Related 
         Documents, (ii) any claim of a party (other than an Indemnified Party)
         relating to any act, omission or obligation of the Company or its 
         stockholders, directors, officers, agents, employees, creditors or 
         Affiliates or (iii) any breach of any written obligation of the 
         Company or its Affiliates to Purchasers, whether or not such
         Indemnified Party is a party thereto and whether or not the
         transactions contemplated herein are consummated.  The Company will
         not be liable to any Indemnified Party under the foregoing
         indemnification provision to the extent that any loss, claim, damage,
         liability or expense incurred by or asserted or awarded against such
         Indemnified Party is found to have resulted from the willful
         misconduct or gross negligence of such Indemnified Party as determined
         by a final judgment of a court of competent jurisdiction.  The
         agreements in this Section 10.4.2 shall survive the Final Maturity
         Date.

         16.5    Right of Set-off.  Subject to Article VII, upon the occurrence
and during the continuance of any Event of Default, Purchasers and any
Assignees are hereby authorized at any time and from time to time, to the
fullest extent permitted by law, to set off and apply any and all deposits
(general or special, time or demand, provisional or final) at any time held and
other Indebtedness at any time owing by Purchasers and any Assignees and
Participants to or for the credit or the account of the Company against any and
all of the Liabilities irrespective of whether or not the Purchasers and any
such Assignees shall have made any demand under this Agreement or the Preferred
Shares and although such obligations may be unmatured.  Purchasers and any
Assignees agree promptly to notify the Company after any such set-off and
application made by Purchasers or any Assignees, provided that the failure to
give such notice shall not affect the validity of such set-off and application.
The rights of Purchasers or any Assignee under this Section 10.5 are in
addition to other rights and remedies (including, without limitation, other
rights of set-off) which such Purchasers or such Assignee may have hereunder,
under the Related Documents, or pursuant to applicable law.

         16.6    Construction.  The use of the singular or plural or masculine
or neuter gender shall not be given an exclusionary meaning and, where
applicable, shall be intended to include the appropriate number or gender, as
the case may be.  The failure of this Agreement to use the term "Sole and
Exclusive Discretion" in connection with any act or failure to act of the
Purchasers hereunder shall not be deemed to imply any obligation on the part of
Purchasers to act or fail to act except in their Sole and Exclusive Discretion.

         16.7    Execution in Counterparts.  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.

         16.8    Binding Effect; Governing Law. This Agreement shall be binding
upon and inure to the benefit of the Company and Purchasers and their
respective successors and assigns, except that the Company shall not have the
right to assign its rights hereunder or any interest herein without the prior






                                Page 31 of 37
<PAGE>   32
written consent of Purchasers.  This Agreement shall be governed by, and
construed in accordance with, the laws of the State of Illinois without regard
to its principles of conflicts of law.

         16.9    Severability.  The invalidity of any provision of this
Agreement or portion of a provision shall not affect the validity of any other
portion of this Agreement or the remaining portion of the applicable provision.

         16.10   Submission to Jurisdiction.  THE COMPANY HEREBY IRREVOCABLY
SUBMITS TO THE JURISDICTION AND EXCLUSIVE VENUE OF ANY STATE OR FEDERAL COURT
LOCATED IN CHICAGO, ILLINOIS, OVER ANY ACTION OR PROCEEDING (i) TO ENFORCE OR
DEFEND ANY RIGHT UNDER THIS AGREEMENT, THE RELATED DOCUMENTS, OR UNDER ANY
AMENDMENT, INSTRUMENT, DOCUMENT, OR AGREEMENT DELIVERED, OR THAT MAY IN THE

        (a)      General Obligation.  When, as and if declared by the Board and
to the extent legally permissible and contractually available therefor, the
Corporation will pay dividends as provided in this Section 5 to the holders of
the Preferred Stock.  Except as otherwise provided herein, dividends on each
share of Preferred Stock will accrue cumulatively, based upon a three-hundred
sixty (360) day year for the actual number of days occurring in the appropriate
Dividend Period, from and including the corresponding Issue Date for the
Initial Dividend Period and for each Dividend Period thereafter, at the Stated
Rate of the Liquidation Value thereof; provided, however, that, if the
Corporation fails to pay dividends on the Preferred Stock within five (5) days
of a Dividend Payment Date ("Dividend Default"), dividends shall accrue at the
Default Rate from the date on which such amount is due until the date on which 
such is paid in full or such Dividend Default is otherwise cured or waived






                                 Page 5 of 17

by the Preferred Stockholders in their Sole and Exclusive Discretion.  Such
dividends will accrue and accumulate whether or not they have been declared and
whether or not there are profits, surplus or other funds of the Corporation
legally available for the payment of dividends.  Dividends will be payable on
each Dividend Payment Date to holders of record as they appear on the stock
books of the Corporation on the corresponding Dividend Payment Record Date.
Dividends on the Preferred Stock shall be paid before any dividends or
distribution is made in respect of any Junior Securities.

                 (b)      Distribution of Partial Dividend Payments.  If at any
         time the Corporation declares less than the total amount of dividends
         then accrued with respect to the Preferred Stock as to dividends, such
         dividends will be payable to the holders of the Preferred Stock,
         ratably per share in proportion to the full per share amounts to which
         they respectively are entitled.

         SECTION 6.       BOARD OF DIRECTORS.  For so long as a Preferred
Stockholder or its Affiliates continue to hold any Preferred Stock or Shares,
the Preferred Stockholders shall be entitled to advance written notice of any
and all meetings of any kind or nature of the Board of Directors of the
Corporation as follows:  (a) 60 days' advance notice in the case of meetings to
be held outside of Cook County, Illinois, (b) 14 days' advance notice in the
case of meetings to be held in Cook County, Illinois, and (c) such lesser
notice as may be required as a result of an emergency, but in no event less
than five days' advance notice.  In addition, any Preferred Stockholder, at its
sole option, shall be entitled to attend, or to have its agents or designees
attend, any or all such meetings in order to ensure continuing compliance with
the terms and conditions contained herein and in the other Related Documents.
The Corporation shall be responsible for paying all fees and expenses
(including, without limitation, travel, lodging, meals and other related
expenses) incurred in connection with attending meetings of the Board of
Directors by any of the above-referenced agents, designees or members of the
Board of Directors designated by the Preferred Stockholders pursuant to this
Section 7, who shall in addition be paid by the Corporation compensation equal
to that paid by the Corporation to Directors who are officers of the
Corporation but who are not paid an annual salary by the Corporation.

         SECTION 7.       CONVERSION.  The Preferred Stock shall be converted
into Shares as follows:

                 (a)      Conversion Right.  Subject to the terms and
         conditions of this Section 7, shares of Preferred Stock owned by
         Preferred Stockholders shall be automatically converted into Shares
         (with full voting rights no less than those of any other Shares) as
         follows:

                          (i)     The total convertible amount represented by
                 the aggregate Purchase Price of the Preferred Stock ("Total
                 Convertible Amount") shall automatically be converted into
                 Shares upon the conversion of the Convertible Secured Notes
                 pursuant to the Convertible Debt Agreement;

                          (ii)    for the purpose of determining the number of
                 Shares into which the Total Convertible Amount may be
                 converted, the principal owed and any other Liabilities
                 (excluding contingent Liabilities the amount of which are not
                 reasonably

        to be held in escrow to be delivered in accordance with Section 7(c) 
        hereof.  For convenience, the conversion of any portion of the Total 
        Convertible Amount represented by the Preferred Stock into Shares is 
        hereinafter sometimes referred to as the "conversion" of the Preferred
        Stock; and

                 (c)      Not later than ten (10) Business Days after the
         surrender of the Preferred Stock for conversion, the Corporation shall
         issue in the name of such Preferred Stockholder and deliver to Agent a
         certificate or certificates for the number of Shares issuable upon the
         conversion in the name of the then registered holder of the Preferred
         Stock.  Such conversion shall be deemed to have been effected as of
         the start of business on the date the conversion of the Convertible
         Secured Notes is effective pursuant to the Convertible Debt Agreement
         (the "Conversion Date") and the Preferred Stock shall have been
         surrendered for conversion as aforesaid, and at such time the Person
         in whose name or names any certificate or certificates for Shares
         shall be issuable upon such conversion shall be deemed to have become
         at such time the holder or holders of record of the Shares represented
         thereby.  In the event that only a portion of shares of Preferred
         Stock held by a Preferred Stockholder is converted, the Corporation
         shall execute and deliver to the Agent, at the expense of the
         Corporation, a reissued Preferred Stock certificate in the name of the
         Preferred Stockholders equal to the number of unconverted shares of
         Preferred Stock.  Upon receipt of such Shares, the original
         certificate for the Preferred Stock and the reissued certificate, if
         any, Agent shall deliver to the Corporation for cancellation the
         original certificate and shall deliver to the holder of the converted
         Preferred Stock such Shares and the reissued certificate, if any.

                 (d)      Reservation.  The Corporation will at all times
         reserve and keep available such number of authorized Shares, solely
         for the purpose of issue upon the conversion of the Preferred Stock as
         herein provided for and the exercise of the conversion rights pursuant
         to the Convertible Debt Agreement, as may at any time be issuable
         (based upon the number of Shares outstanding at any such time) upon
         the conversion of Preferred Stock and the conversion of any
         Convertible Secured Notes, and such Shares issuable upon the exercise
         of the conversion rights of the Preferred Stock and the Convertible
         Secured Notes shall at no time have an aggregate par value which is in
         excess of the portion of the Total Convertible Amount that will be
         converted into one Share upon the conversion of the Preferred Stock
         and the conversion of any Convertible Secured Notes.

                 Notwithstanding the foregoing, the Corporation and Preferred
         Stockholders acknowledge that as of the Closing Date, the Corporation
         has 16,880,130 authorized Shares available for the purpose of issuing
         upon the conversion of the Preferred Stock and the Convertible Secured
         Notes.  Based on the Corporation's representation that there are
         13,493,205 Fully Diluted Shares, the 16,880,130 Shares available for
         issue upon the conversion described in the previous sentence may be
         issued in exchange for approximately $4,508,234.00 of the Total
         Convertible Amount represented by the Preferred Stock and the
         Convertible Secured Notes.  If the Total Convertible Amount
         represented by the Preferred Stock and the Convertible Secured Notes
         rises above said amount, and if the Preferred Stock




                                 Page 10 of 17
<PAGE>   48
         or the Convertible Secured Notes are converted, or the Corporation
         otherwise issues additional Shares, then unless additional Shares have
         been authorized, the Preferred Stockholders would be unable to effect
         the conversion of all of their shares of Preferred Stock and Lender
         would be unable to effect the conversion of the total amount of the
         convertible secured notes issued pursuant to the Convertible Debt
         Agreement.  In such an event, the Corporation will take all actions
         necessary to increase the number of its authorized Shares in an amount
         sufficient to issue all Shares issuable upon the conversion of the
         Preferred Stock and the Convertible Secured Notes and, to the extent
         that approval of the stockholders of the Corporation is required for
         such increase, will use its best efforts to secure such approval.
         Furthermore, in the event that there are insufficient authorized
         Shares, the Corporation will not issue or commit to issue any Shares
         other than pursuant to the conversion of Preferred Stock pursuant to
         this Section 7 and pursuant to the conversion of the Convertible
         Secured Notes until a sufficient number of Shares are authorized.

                 (e)      Mergers, Consolidations, Sales.  In the case of any
         consolidation or merger of the Corporation with another entity, or the
         sale of all or substantially all of its assets to another entity, or
         any reorganization or reclassification of the Shares or other equity
         securities of the Corporation, then, as a condition of such
         consolidation, merger, sale, reorganization or reclassification,
         lawful and adequate provision shall be made whereby the Preferred
         Stockholders shall thereafter have the right to receive upon the basis
         and upon the terms and conditions specified herein and in lieu of the
         Shares that theretofore would have been received upon conversion of
         the Preferred Stock, such shares of stock, securities or assets as may
         be (by virtue of such consolidation, merger, sale, reorganization or
         reclassification) be issued or payable with respect to or in exchange
         for a number of outstanding Shares equal to the number of Shares
         immediately theretofore so purchasable by conversion hereunder had
         such consolidation, merger, sale, reorganization or reclassification
         not taken place, and in any such case appropriate provisions shall be
         made with respect to the rights and interests of the Preferred
         Stockholders to the end that the provisions hereof shall thereafter be
         applicable, as nearly as may be, in relation to any shares of stock,
         securities or assets thereafter deliverable upon exercise of the
         conversion rights of the Preferred Stock.  The Corporation shall not
         effect any such consolidation, merger or sale, unless prior to or
         simultaneously with the consummation thereof, the successor entity (if
         other than the Corporation) resulting from such consolidation or
         merger or the entity purchasing such assets shall assume by written
         instrument executed and mailed or delivered to the Preferred
         Stockholders, the obligation to deliver to such holder such shares of
         stock, securities or assets as, in accordance with the foregoing
         provisions, such holder may be entitled to receive.  Nothing contained
         in this Section 7(e) shall permit the Corporation to take any action
         or enter into any transaction which is prevented or prohibited by any
         other provision of this Certificate of Designation, the Preferred
         Stock Purchase Agreement or the other Related Documents.

                 (f)      Dissolution or Liquidation.  In the event of any
         proposed distribution of the assets of the Corporation in complete
         dissolution or liquidation except under circumstances when the
         foregoing Section 7(e) shall be applicable, the Corporation shall give
         notice thereof to the Preferred Stockholders and shall make no
         distribution to shareholders until the expiration of one-hundred
         twenty (120) days from the date of giving of the aforesaid notice and,
         in any such case, the Preferred Stockholders may exercise the
         conversion rights, if and when the holders of the Convertible Secured
         Notes have exercised their conversion rights, with respect to
         Preferred Stock within one-hundred (120) days from the date of giving
         such notice and, upon the timely completion of such distribution or
         liquidation, all conversion rights herein granted not so exercised
         within such 120-day period shall thereafter become null and void.

                 (g)      Notice of Dividends.  If the Board of Directors of
         the Corporation shall declare any dividend or other distribution on
         the Shares, the Corporation shall give notice thereof to the Preferred
         Stockholders not less than one-hundred twenty (120) days prior to the
         record date fixed for determining shareholders entitled to participate
         in such dividend or other distribution and the Preferred Stockholders
         may exercise the conversion rights of the Preferred Stock, if and when
         the holders of the Convertible Secured Notes have exercised their
         conversion rights.  The provisions of this section shall not apply to
         distributions made in connection with transactions covered by Section
         7(e).

                 (h)      Fractional Shares.  Fractional Shares may be issued
         upon the exercise of the conversion rights of the Preferred Stock in
         any case where the holder hereof would be entitled to receive a
         fractional Share upon the exercise of the conversion rights of the
         Preferred Stock in order to receive the appropriate percentage of
         Fully Diluted Shares; provided, that at its election, any holder may
         elect to receive in lieu of any fractional Share that it would
         otherwise receive cash in the amount of such fraction of the fair
         market value of a Share.

                 (i)      Fully Paid Stock; Taxes.  The Corporation covenants
         and agrees that the shares of stock represented by each and every
         certificate for Shares to be delivered on the exercise of the
         conversion rights herein provided for shall, at the time of such
         delivery, be validly issued and outstanding and be fully paid and
         nonassessable.  The Corporation further covenants and agrees that it
         will pay when due and payable any and all federal and state taxes
         (other than income taxes) which may be payable in respect of the
         exercise of conversion rights by Preferred Stockholders or any Shares
         or certificates therefor upon the exercise of the conversion rights
         herein provided for pursuant to the provisions hereof.

         SECTION 8.       LIMITED CALL RIGHT.  During the period commencing on
the date that the sum of (a) the aggregate Purchase Price paid for Preferred
Stock purchased pursuant to the Preferred Stock Purchase Agreement and (b) the
aggregate initial principal amount of Convertible Secured Notes issued pursuant
to the Convertible Debt Agreement amounts to One Dollar ($1.00) or more and
ending on the earlier to occur of one (1) year after the Closing Date under the
Preferred Stock Purchase Agreement or when no Preferred Stock remains
outstanding and no Indebtedness remains outstanding under the Convertible
Secured Notes, the Corporation may give the Preferred Stockholders (or their
transferees) notice of its intention to purchase and redeem ("Call") all (but
not



                                      
                                Page 12 of 17
<PAGE>   50
less than all) of the outstanding shares of Preferred Stock (collectively, the
"Called Stock") if the conditions described in Section 8(a) hereof have been
complied with at and prior to the time of the Corporation's exercise of the
Call, and thereupon Preferred Stockholders (or its transferees) shall sell to
the Company the Called Stock as provided in this Section 8.

                 (a)      CONDITIONS TO CALL.  The Call may be exercised and
         consummated only if:  (i) no Event of Default has occurred and is
         continuing nor any Event of Default would occur, after giving effect
         to the exercise of the Call, with the passage of time, the giving of
         notice, or both; (ii) the exercise of the Call is not prohibited by
         applicable corporate or other law or pursuant to the terms or
         covenants of any loan agreement, note, security agreement or other
         instrument binding upon the Company; (iii) concurrently therewith, the
         Corporation calls for redemption that portion of the Convertible
         Secured Notes (the "Called Debt") which bears the same percentage of
         the total outstanding indebtedness under the Convertible Secured Notes
         as the Called Stock bears to the total outstanding shares of Preferred
         Stock; (iv) all accumulated dividends on the Preferred Stock have been
         paid; (v) concurrently therewith, the Corporation either (A) deposits
         in escrow with Agent an amount in cash equal to five percent of the
         Call Price (the "Deposit") or (B) delivers to the Preferred
         Stockholders a written, unconditional commitment from a third party to
         provide funds sufficient to consummate the Call and evidence
         satisfactory to the holders of a majority of the Preferred Stock that
         such third party has sufficient liquid assets available for that
         purpose; and (vi) the Preferred Stockholders do not exercise their
         right to convert the Called Stock within ninety (90) Business Days
         after the Call is made.  At the closing of the Call, the Deposit, if
         made under clause (A) above, shall be paid by Agent to the Preferred
         Stockholders and applied against the Call Price.  If the Call fails to
         close in accordance with or within the time period provided in Section
         8(d) (other than due to the Preferred Stockholders' default or to the
         conversion of the Called Stock), the Deposit, if made under clause (A)
         above, shall be paid by Agent to the Preferred Stockholders as
         liquidated damages, such failure to close shall constitute an Event of
         Default and the Corporation shall not be entitled to close the Call or
         to make any subsequent Call.

                 (b)      [INTENTIONALLY DELETED].

                 (c)      CALL PRICE.  The purchase price ("Call Price") of the
         Called Stock shall be equal to the Liquidation Value thereof plus (a)
         if the Call is made within one-hundred eighty (180) days after the
         Closing Date, a premium of $375,000, (b) if the Call is made more than
         one-hundred eighty (180) days but within two-hundred seventy (270)
         days after the Closing Date, a premium of $500,000, and (c) if the
         call is made more than two-hundred seventy (270) days but within
         three-hundred sixty (360) days after the Closing Date, a premium of
         $750,000.  The portion of the Call Price determined under clause (a),
         (b) or (c) of the preceding sentence (the "Premium") shall be
         allocated among the Preferred Stockholders and the holders of the
         Convertible Secured Notes in proportion to the ratio that the
         Liquidation Value of the Called Stock bears to the amount of the
         Indebtedness (as defined in the Convertible Debt Agreement)
         represented by the Called Debt.  The portion of the Premium allocable
         to the Preferred Stockholders shall be allocated among the Preferred
         Stockholders in accordance with the amount of Preferred Stock of each
         Preferred Stockholder being Called.

<PAGE>   51
                 (d)      EXERCISE OF CALL.  The Corporation may exercise the
         Call (subject to the terms and conditions hereinabove set forth) by
         delivery to the Preferred Stockholders during the period of the
         effectiveness of the Call of written notice of exercise of the Call,
         which notice shall specify the number of shares of the Preferred Stock
         which the Corporation elects to Call and shall contain a statement,
         certified by the Chief Executive Officer of the Corporation, that each
         of the conditions to the exercise and to the closing of the Call
         hereinabove set forth has been fulfilled.  The closing of the Call
         shall take place at the principal offices of the Preferred
         Stockholders on or before one-hundred ten (110) Business Days after
         the exercise of the Call and shall take place concurrently with the
         redemption of the Called Debt; provided, however, that if any
         Preferred Stockholder agrees by written notice to the Corporation to
         accept the Call as to any portion of the Called Stock and to waive its
         right to convert such portion of the Called Stock prior to the
         expiration of such conversion right, the closing of the Call as to
         such portion of the Called Stock shall take place within 20 Business
         Days after such notice is given.  At the closing, Agent (a) shall
         receive from the Corporation by wire transfer immediately available
         funds in an amount equal to the Call Price, plus all unpaid,
         accumulated dividends thereon, and (b) shall receive from the
         Preferred Stockholders the stock certificate for the Preferred Stock
         Called duly endorsed or assigned to the Corporation.  Upon receipt of
         all of such items, Agent shall deliver to the Corporation the stock
         certificate for the Called Stock for cancellation and shall deliver to
         the Preferred Stockholders the above funds.

                 (e)      NO OTHER CALL RIGHTS.  Except as permitted in this
         Section 8, the Corporation shall not be entitled to call the
         outstanding Preferred Stock.

         SECTION 9.       PREEMPTIVE RIGHTS UPON THE ISSUANCE OF CAPITAL STOCK
BY COMPANY.  At any time that shares of Preferred Stock are outstanding or a
Preferred Stockholder or its transferees own any Shares or other securities in
the Corporation, if the Corporation proposes to issue any Shares or any
security or obligation which by its terms is convertible into Shares or any
warrant, option or other subscription or purchase right with respect to Shares
other than pursuant to the Warrant, Other Warrant, or pursuant to the
conversion rights granted under the Convertible Debt Agreement or the Preferred
Stock, the Corporation shall first deliver to the Preferred Stockholder a
notice with respect to such proposed issuance which sets forth the price and
number of Shares or other such securities which it proposes to issue.  The
Preferred Stockholders shall have the right to purchase such offered securities
at the proposed issuance price (or, if such securities are to be issued in
consideration of services rendered or upon the conversion or exercise of
convertible securities, warrants or options heretofore issued by the
Corporation, a sufficient amount of newly issued securities such that the
Preferred Stockholders would suffer no dilution, at an amount equal to the fair
value of such services or the actual consideration received by the Corporation
upon such conversion or exercise), which right shall be exercisable by the
Preferred Stockholders by written notice to the Corporation given on or before
ninety (90) days after receipt by Preferred Stockholders of written notice of
such proposed issuance.  Such right shall accrue to Lender and all holders of
the Preferred Stock.  If only the Preferred Stockholders exercise such right,
they may exercise such right as to any or all of such Shares or other
securities.  If Lender and one or more Preferred Stockholders exercise such
right, such Preferred Stockholders shall have the right to purchase that
portion of the Shares or other securities purchasable under this section as the
aggregate Purchase Price of the Preferred Stock held by all holders exercising
such right bears to the sum of the unpaid principal amount of Lender's
Convertible Secured Notes and the aggregate purchase price of Preferred Stock
held by all holders exercising such right (unless Lender and such exercising
holders





                                Page 14 of 17
<PAGE>   52
agree otherwise). In the event Preferred Stockholders do not exercise the 
option under this Section 9, the Corporation may issue the offered securities 
in the amount and at the price set forth in such notice to the Preferred 
Stockholders within one-hundred eighty (180) days of the date of such notice. 
The closing of any purchase by the Preferred Stockholders under this Section 9
shall be held at the principal office of the Preferred Stockholders at 
11:00 a.m. local time on the one-hundred fiftieth (150th) day after the date 
on which the Preferred Stockholders first shall have received notice of the 
proposed issuance, or at such other time and place as the parties to the
transaction may agree.  Notwithstanding the foregoing, nothing contained in 
this Section 9 will waive the Preferred Stockholders' right to prevent or 
object to the issuance of Shares or any other securities by the Corporation or
its Subsidiaries.

         SECTION 10.  REGISTRATION OF TRANSFER.  The Corporation will keep at
its principal office a register for the registration of Preferred Stock.  Upon
the surrender of any certificate representing Preferred Stock at such place,
the Corporation will, at the request of the record holder of such certificate,
execute and deliver (at the Corporation's expense) a new certificate or
certificates in exchange therefor representing in the aggregate the number of
shares represented by the surrendered certificate.  Each such new certificate
will be registered in such name and will represent such number of shares as is
requested by the holder of the surrendered certificate and will be
substantially identical in form to the surrendered certificate, and dividends
will accrue on the Preferred Stock represented by such new certificate from the
date to which dividends have been fully paid on such Preferred Stock
represented by the surrendered certificate.

         SECTION 11.  REPLACEMENT.  Upon receipt of the evidence reasonably
satisfactory to the Corporation (an affidavit of the registered holder will be
satisfactory) of the ownership and the loss, theft, destruction or mutilation
of any certificate evidencing shares of Preferred Stock, and in the case of any
such loss, theft or destruction, upon receipt of indemnity reasonably
satisfactory to the Corporation, or, in the case of any such mutilation upon
surrender of such certificate, the Corporation will (at its expense) execute
and deliver in lieu of such certificate a new certificate of like kind
representing the number of shares represented by such lost, stolen, or
destroyed or mutilated certificate and dated the date of such lost, stolen,
destroyed or mutilated certificate, and dividends will accrue on the Preferred
Stock represented by such new certificate from the date to which dividends have
been fully paid on such lost, stolen, destroyed or mutilated certificate.

         SECTION 12.  AMENDMENT.  No amendment, modification or waiver will be
binding or effective with respect to any provision of this Certificate of
Designation without the prior written consent of the holders of at least a
majority of the then outstanding shares of Preferred Stock. The Corporation
shall not take any action which may have the effect of diluting the rights of
the Preferred Stockholders, including, without limitation, authorizing a stock
split or combination with respect to the Preferred Stock, changing the number
of shares of Preferred Stock authorized or issuing Preferred Stock to any
person or entity other than the purchasers under the Preferred Stock Purchase
Agreement, without the prior written consent of the holders of at least a
majority of the then outstanding shares of Preferred Stock. 

         SECTION 13.  NOTICE. All notices, requests and other communications
provided for hereunder shall be in writing and sent by first class mail
registered or certified, postage prepaid and return receipt requested or
delivered personally or by courier against written acknowledgement of receipt
(i) if to the Corporation, at 2358 Hassell Road, Hoffman Estates, Illinois
60195, with a copy to John F. Mahoney,

Esq., Chuhak & Tecson, P.C., 225 West Washington Street, Suite 1300, Chicago, 
Illinois, 60606, (ii) if to a Preferred Stockholder, at such holder's address 
as it appears in the stock records of the Corporation (unless otherwise 
indicated by such holder).  All such notices and other communications shall be
effective on the date of delivery to the party receiving such notice, as 
evidenced by the date set forth on the receipt signed by the party receiving 
such notice.

         SECTION 14.  OBLIGATION TO SELL PREFERRED STOCK.  If at any time the
holders of a majority of the Indebtedness evidenced by the Convertible Secured
Notes receive a bona fide, arm's length written offer from a party which is not
an Affiliate of such holders to purchase all of the Convertible Secured Notes
for monetary consideration, and wish to accept such offer, (a) they shall give
prompt written notice of such offer to the Preferred Stockholders, including a
copy of all documents relating thereto, (b) they shall not accept such offer
unless the offeror agrees, simultaneously with such sale, to purchase all of
the outstanding Preferred Stock on the same terms and conditions and at the
same proportional price as is being paid for the Convertible Secured Notes, and
(c) the Preferred Stockholders shall be required to sell their Preferred Stock
on such terms and conditions.  Any Preferred Stockholder in breach of this
Section shall pay the holders of the Convertible Secured Notes, on demand, all
costs and expenses, including attorneys' fees, incurred by such holders in
enforcing their rights under this section.

         1.      Definitions.  Unless defined otherwise, any term used herein
which has the first letters thereof capitalized, exclusive of prepositions and
articles, shall be defined as such capitalized term is defined in that certain
Series A 11.75% Cumulative Convertible Preferred Stock Purchase Agreement,
dated as of April 22, 1996 ("Purchase Agreement"), by and between the Parties
(which such Purchase Agreement is hereby incorporated herein and made a part
hereof by this reference thereto).

         2.      Exercise of Warrant.  The Holder of this Warrant shall be
entitled to purchase such numbers of Shares at any time over approximately a
ten (10) year period commencing on the effective date of this Warrant and
ending at 6:01 P.M. Eastern Standard Time on the date ten (10) years after such

         In case the Holder of this Warrant shall desire from time to time to

                                 Page 1 of 8
<PAGE>   56
exercise notice marked Exhibit B, which is attached hereto, incorporated herein
and made a part hereof by this reference thereto, duly executed by the Holder
(said exercise notice shall bear an original signature of the Holder), to the
Company, accompanied by payment of the Exercise Price.

         This Warrant may be exercised in whole or in part but not for
fractional Shares.  In case of the exercise in part only, the Company shall
immediately deliver to the Holder a new Warrant of like tenor for the remaining
Shares.  This Warrant, at any time prior to the exercise hereof, upon
presentation and surrender to the Company may be exchanged for another Warrant
or other Warrants of like tenor in the name of such Holder exercisable for the
same aggregate number of Shares as the Warrant or Warrants surrendered.

         3.      No Voting Rights.  This Warrant shall not entitle the Holder
hereof to any voting right (except as required by law) or to other rights as a
shareholder of the Company.  However, Holders of Shares received upon exercise
of this Warrant shall have such voting rights and all other rights as other
shareholders of the Company.

         4.      Covenants of the Company.  The Company hereby covenants and
agrees that prior to the expiration of this Warrant by exercise or by its
terms:

                 a.       The Company will not by amendment of its Certificate
of Incorporation or through reorganization, consolidation, merger, dissolution,
or sale of assets, or by any other voluntary act or deed, avoid or seek to
avoid the observance or performance of any of the covenants, stipulations or
conditions to be observed or performed hereunder by the Company, but will at
all times in good faith assist in the carrying out of all provisions of this
Warrant and in the taking of all other actions that may be necessary in order
to protect the rights of the Holder against dilution.

                 b.       The Company shall not issue any shares of common
stock or any other equity of the Company without the prior written consent of
Holder, and upon any such issuance, this Warrant shall be modified so that the
number of shares issuable hereunder shall represent the same percentage of the
fully diluted equity of the Company as before such issuance.

                 c.       The Company shall at all times reserve and keep
available, out of its authorized and unissued share capital, solely for the
purpose of providing for the exercise of the Warrant, forthwith upon the
request of the Holder of the Warrants then outstanding and in effect, such
numbers of Shares as shall, from time to time, be sufficient for the exercise
in full of the Warrants.  The Company shall, from time to time, in accordance
with the laws of the State of Delaware, increase the authorized amount of its
share capital if at any time the number of Shares remaining unissued and
unreserved for other purposes shall not be sufficient to permit the exercise of
the Warrants then outstanding and in effect.

         Notwithstanding the foregoing, the Company and the Holder acknowledge
that as of the date of this Warrant, the Company has 16,880,130 shares of
authorized and unissued shares of its common




                                 Page 2 of 8
<PAGE>   57
stock available for the purpose of issue upon (1) the exercise, in whole, of
the conversion rights of the Series A 11.75% Cumulative Convertible Preferred
Stock of the Company (the "Series A Preferred Stock") and the convertible
secured notes issued pursuant to that certain Convertible Debt Agreement dated
as of April 22, 1996 by and between the Company and Amsterdam Equities Limited
("Convertible Debt Agreement") and (2) the exercise, in whole, of this Warrant,
the FLL Warrant, Laport Warrant and the Amsterdam Warrant No. 1 (collectively,
the "Other Warrants").  If the amount, of shares authorized and unissued is
insufficient, to effect, in whole, the conversion and/or exercise in whole, of
the Preferred Stock, the convertible secured notes issued pursuant to the
Convertible Debt Agreement, this Warrant and the Other Warrants, (2) then, upon
the request of the Holder, the Company shall take all actions necessary to
increase the number of authorized shares in an amount sufficient to issue all
shares issuable pursuant to the conversion rights represented by the
Convertible Secured Notes, the Series A Preferred Stock, and the exercise of
this Warrant and the Other Warrants.

         5.      Loss, Theft, Destruction or Mutilation.  In case this Warrant
shall become mutilated or defaced or be destroyed, lost or stolen, the Company
shall execute and deliver a new Warrant in exchange for and upon surrender and
cancellation of such mutilated or defaced Warrant or in lieu of and
substitution for such Warrant so destroyed, lost or stolen, upon the Holder of
such Warrant filing with the Company such reasonable evidence (an affidavit
shall suffice) that such Warrant has been so mutilated, defaced, destroyed,
lost or stolen and of the ownership thereof by the Holder; provided, however,
that the Company shall be entitled, as a condition to the execution and
delivery of such new Warrant, to demand reasonable indemnity and payment of
expenses and charges incurred in connection with the delivery of such new
Warrant, and may, if reasonable under the circumstances, request a bond from
the Holder.  All Warrants so surrendered to the Company shall be canceled.

         6.      Record Owner.  At the time of the surrender of this Warrant,
together with the payment of the Exercise Price, the person exercising this
Warrant shall be deemed to be the Holder of record of the Warrants deliverable
upon such exercise, in whole or in part, notwithstanding that the stock
transfer books of the Company shall then be closed or that certificates
representing such securities shall not then be actually delivered to such
person.

         7.      Fractional Securities.  No fractional Shares, fractional
warrants, fractional shares or scrip representing fractional shares shall be
issued upon the exercise of this Warrant.  With respect to any fraction of a
share called for on such exercise, the Holder may elect to remit to the Company
an amount in cash equal to the difference between such fraction and one,
multiplied by the Exercise Price, and the Company will issue the Holder one
Share in addition to the number of whole shares required by the exercise of the
Warrant.

         8.      Original Issue Taxes.  The Company shall pay all United
States, state, local and any other original issue taxes, if any, upon the
issuance of this Warrant or the Shares deliverable upon exercise hereof.

         3.      No Voting Rights.  This Warrant shall not entitle the Holder
hereof to any voting right (except as required by law) or to other rights as a

         4.      Covenants of the Company.  The Company hereby covenants and
agrees that prior to the expiration of this Warrant by exercise or by its

                 c.       The Company shall at all times reserve and keep
available, out of its authorized and unissued share capital, solely for the
purpose of providing for the exercise of the Warrant, forthwith upon the
request of the Holder of the Warrants then outstanding and in effect, such
numbers of Shares as shall, from time to time, be sufficient for the exercise
in full of the Warrants.  The Company shall, from time to time, in accordance

<PAGE>   65
         Notwithstanding the foregoing, the Company and the Holder acknowledge

the Company and Amsterdam Equities Limited ("Convertible Debt Agreement") and
(2) the exercise, in whole, of this Warrant, the Laport Warrant, the Amsterdam
Warrant No. 1 and the Amsterdam Warrant No. 2 (collectively, the "Other
Warrants").  If the amount, of shares authorized and unissued is insufficient,
to effect, in whole, the conversion and/or exercise in whole, of the Preferred
Stock, the convertible secured notes issued pursuant to the Convertible Debt
Agreement, this Warrant and the Other Warrants, (2) then, upon the request of
the Holder, the Company shall take all actions necessary to increase the number

such Warrant filing with the Company such reasonable evidence (an affidavit
shall suffice) that such Warrant has been so mutilated, defaced, destroyed,

         6.      Record Owner.  At the time of the surrender of this Warrant,
together with the payment of the Exercise Price, the person exercising this

warrants, fractional shares or scrip representing fractional shares shall be
issued upon the exercise of this Warrant.  With respect to any fraction of a
share called for on such exercise, the Holder may elect to remit to the Company
an amount in cash equal to the difference between such fraction and one,
multiplied by the Exercise Price, and the Company will issue the Holder one
Share in addition to the number of whole shares required by the exercise of the
Warrant.

         THE TERMS OF THIS WARRANT.


                           WARRANT TO PURCHASE UP TO
                 134,062 UNREGISTERED SHARES OF COMMON STOCK OF
                    PRINCETON DENTAL MANAGEMENT CORPORATION

NO. __


         FOR VALUE RECEIVED, Princeton Dental Management Corporation, a
Delaware corporation located at 2358 Hassell Road, Hoffman Estates, Illinois
60195 (the "Company"), promises to issue in the name of, and sell and deliver
to the party identified on Exhibit A attached hereto and incorporated herein,
together with its successors, transferees and assigns (the "Holder") (when the
context requires, the Company and the Holder shall be collectively referred to
as the "Parties"), a certificate or certificates for an aggregate of One
Hundred Thirty Four Thousand Sixty Two (134,062) unregistered shares of Common
Stock, One Ten Thousandth of One United States Dollar (U.S.$.0001) par value
per share (the "Shares"), of the Company, upon payment therefor of Ten United
States Cents ($0.10) per Share in lawful funds of the United States of America
(the "Exercise Price") pursuant to the terms hereof.

         1.      Definitions.  Unless defined otherwise, any term used herein
which has the first letters thereof capitalized, exclusive of prepositions and
articles, shall be defined as such capitalized term is defined in that certain
Series A 11.75% Cumulative Convertible Preferred Stock Purchase Agreement,
dated as of April 22, 1996 ("Purchase Agreement"), by and between the Parties
(which such Purchase Agreement is hereby incorporated herein and made a part
hereof by this reference thereto).

         2.      Exercise of Warrant.  The Holder of this Warrant shall be
entitled to purchase such numbers of Shares at any time over approximately a
ten (10) year period commencing on the effective date of this Warrant and
ending at 6:01 P.M. Eastern Standard Time on the date ten (10) years after such
date.

         In case the Holder of this Warrant shall desire from time to time to
exercise this Warrant in whole or in part, the Holder shall surrender a copy of
this Warrant, with a copy of the form





 
                                      
                                 Page 1 of 8
<PAGE>   72
of exercise notice marked Exhibit B, which is attached hereto, incorporated
herein and made a part hereof by this reference thereto, duly executed by the
Holder (said exercise notice shall bear an original signature of the Holder),
to the Company, accompanied by payment of the Exercise Price.

         This Warrant may be exercised in whole or in part but not for
fractional Shares.  In case of the exercise in part only, the Company shall
immediately deliver to the Holder a new Warrant of like tenor for the remaining
Shares.  This Warrant, at any time prior to the exercise hereof, upon
presentation and surrender to the Company may be exchanged for another Warrant
or other Warrants of like tenor in the name of such Holder exercisable for the
same aggregate number of Shares as the Warrant or Warrants surrendered.

         3.      No Voting Rights.  This Warrant shall not entitle the Holder
hereof to any voting right (except as required by law) or to other rights as a
shareholder of the Company.  However, Holders of Shares received upon exercise
of this Warrant shall have such voting rights and all other rights as other
shareholders of the Company.

         4.      Covenants of the Company.  The Company hereby covenants and
agrees that prior to the expiration of this Warrant by exercise or by its
terms:

                 a.       The Company will not by amendment of its Certificate
of Incorporation or through reorganization, consolidation, merger, dissolution,
or sale of assets, or by any other voluntary act or deed, avoid or seek to
avoid the observance or performance of any of the covenants, stipulations or
conditions to be observed or performed hereunder by the Company, but will at
all times in good faith assist in the carrying out of all provisions of this
Warrant and in the taking of all other actions that may be necessary in order
to protect the rights of the Holder against dilution.

                 b.       The Company shall not issue any shares of common
stock or any other equity of the Company without the prior written consent of
Holder, and upon any such issuance, this Warrant shall be modified so that the
number of shares issuable hereunder shall represent the same percentage of the
fully diluted equity of the Company as before such issuance.

                 c.       The Company shall at all times reserve and keep
available, out of its authorized and unissued share capital, solely for the
purpose of providing for the exercise of the Warrant, forthwith upon the
request of the Holder of the Warrants then outstanding and in effect, such
numbers of Shares as shall, from time to time, be sufficient for the exercise
in full of the Warrants.  The Company shall, from time to time, in accordance
with the laws of the State of Delaware, increase the authorized amount of its
share capital if at any time the number of Shares remaining unissued and
unreserved for other purposes shall not be sufficient to permit the exercise of
the Warrants then outstanding and in effect.





 

                                 Page 2 of 8
<PAGE>   73
         Notwithstanding the foregoing, the Company and the Holder acknowledge
that as of the date of this Warrant, the Company has 16,880,130 shares of
authorized and unissued shares of its common stock available for the purpose of
issue upon (1) the exercise, in whole, of the conversion rights of the Series A
11.75% Cumulative Convertible Preferred Stock of the Company (the "Series A
Preferred Stock") and the convertible secured notes issued pursuant to that
certain Convertible Debt Agreement dated as of April 22, 1996 by and between
the Company and Amsterdam Equities Limited ("Convertible Debt Agreement") and
(2) the exercise, in whole, of this Warrant, the FLL Warrant, the Amsterdam
Warrant No. 1 and the Amsterdam Warrant No. 2 (collectively, the "Other
Warrants").  If the amount, of shares authorized and unissued is insufficient,
to effect, in whole, the conversion and/or exercise in whole, of the Preferred
Stock, the convertible secured notes issued pursuant to the Convertible Debt
Agreement, this Warrant and the Other Warrants, (2) then, upon the request of
the Holder, the Company shall take all actions necessary to increase the number
of authorized shares in an amount sufficient to issue all shares issuable
pursuant to the conversion rights represented by the Convertible Secured Notes,
the Series A Preferred Stock, and the exercise of this Warrant and the Other
Warrants.

         5.      Loss, Theft, Destruction or Mutilation.  In case this Warrant
shall become mutilated or defaced or be destroyed, lost or stolen, the Company
shall execute and deliver a new Warrant in exchange for and upon surrender and
cancellation of such mutilated or defaced Warrant or in lieu of and
substitution for such Warrant so destroyed, lost or stolen, upon the Holder of
such Warrant filing with the Company such reasonable evidence (an affidavit
shall suffice) that such Warrant has been so mutilated, defaced, destroyed,
lost or stolen and of the ownership thereof by the Holder; provided, however,
that the Company shall be entitled, as a condition to the execution and
delivery of such new Warrant, to demand reasonable indemnity and payment of
expenses and charges incurred in connection with the delivery of such new
Warrant, and may, if reasonable under the circumstances, request a bond from
the Holder.  All Warrants so surrendered to the Company shall be canceled.

         6.      Record Owner.  At the time of the surrender of this Warrant,
together with the payment of the Exercise Price, the person exercising this
Warrant shall be deemed to be the Holder of record of the Warrants deliverable
upon such exercise, in whole or in part, notwithstanding that the stock
transfer books of the Company shall then be closed or that certificates
representing such securities shall not then be actually delivered to such
person.

         7.      Fractional Securities.  No fractional Shares, fractional
warrants, fractional shares or scrip representing fractional shares shall be
issued upon the exercise of this Warrant.  With respect to any fraction of a
share called for on such exercise, the Holder may elect to remit to the Company
an amount in cash equal to the difference between such fraction and one,
multiplied by the Exercise Price, and the Company will issue the Holder one
Share in addition to the number of whole shares required by the exercise of the
Warrant.

         8.      Original Issue Taxes.  The Company shall pay all United
States, state, local and any other original issue taxes, if any, upon the
issuance of this Warrant or the Shares deliverable upon exercise hereof.

of 1933, as amended, or applicable state securities laws.

                          (d)     Registrable Securities:  The term
                 "Registrable Securities" shall be defined as: (i) any and all
                 shares of Common Stock of the Company issued pursuant to the
                 terms of the Purchase Agreement including, without limitation,
                 (A) all shares of Common Stock of the Company obtained as a
                 result of the conversion of the Preferred Stock pursuant to
                 Section 7 of the Certificate of Designation of the Preferred

                 Unregistered Shares, 134,063 Unregistered Shares and 134,062
                 Unregistered Shares (respectively) Of Common Stock Of
                 Princeton Dental Management Corporation dated as of April 22,
                 1996 issued to Amsterdam, FLL and Laport IRA, respectively,
                 and (iii) any securities issued or issuable in respect to
                 securities included in foregoing items (i)-(ii) (the "Primary
                 Securities") by way of any distribution of securities or
                 pursuant to any stock dividend, stock split or combination,
                 recapitalization, merger, consolidation, or other
                 reorganization of the Company affecting the Primary
                 Securities.  For purposes of this Agreement, a Person will be
                 deemed to be a holder of Registrable Securities whenever such
                 Person has the right to acquire such Registrable Securities
                 (upon conversion or exercise in connection with a transfer of
                 securities or otherwise, but disregarding any restrictions or
                 limitations upon the exercise of such right), whether or not
                 such acquisition has actually been effected.

         2.      Registration Rights.  At any time and from time to time after
the date hereof, the Company shall file and use its best efforts to cause to
become effective a registration statement to register any and all Registrable
Securities under the Act (a "Demand Registration") when and as directed by the
then holders of a majority of the Amsterdam Registrable Securities.  Each
written request for a registration shall specify the approximate number of
Registrable Securities requested to be registered, the identity of the holders
of Registrable Securities demanding such registration, the form such
registration is to be effected on and the anticipated per share price range for
such offering.  Within ten (10) days after receipt of notice of registration,
the Company shall give written notice of such demand to all other holders of
Registrable Securities.  The Company will include in such registration all
Registrable Securities with respect to which the Company has received written
requests for inclusion therein within twenty (20) days after the date of the
Company's notice of the registration to holders of Registrable Securities.  The
Company shall file and use its best efforts to cause to become effective a
registration statement covering all Registrable Securities to be so registered
under the Act no later than the ninetieth (90th) calendar day from the date of
the original notice to the Company.  If the Company is unable to so register
such Registrable Securities within ninety (90) calendar days, then the Company
shall issue pro rata to each holder of Registrable Securities who had requested
such registration additional shares of Common Stock (which shall be Registrable
Securities) in the amount equal to the product of (i) the number of Registrable
Securities requested to be registered by such holder, and (ii) the difference
between the fair market value of a share of Common Stock on the business day
immediately following the ninetieth (90th) calendar day after which the notice
to register was delivered (as determined by the average of the NASDAQ high and
low sales price on such business day (or whatever market quotation as may be
relevant at the time)) and the fair market value of a share of Common Stock on
the business day immediately following the effective date of the registration
statement (as defined in Section 3(l)) covering such shares of Common Stock (as
determined by the average of the NASDAQ high and low sales price per share on 
such day (or whatever market quotation as may be relevant at the time)); 
provided, however, that if the fair market value of such a share has, in such





                                 Page 2 of 13
<PAGE>   81
         instance, increased, the Company shall not be required to grant
         to the holders of Registrable Securities then registering their shares
         any additional shares of Common Stock; further, provided, that in no
         event shall any holder of Registrable Securities ever be required to
         return any shares of Common Stock to the Company pursuant to the terms
         hereof.  Once any registration pursuant to this Section 2 is
         commenced, the Company shall use its best efforts to complete such
         registration as expeditiously as possible.  All expenses incurred in
         connection with such registration shall be paid by the Company as
         provided in Section 4 herein.

                 In the event any securities to be sold by holders of
Registrable Securities pursuant to a registration under this Section 2 are not
sold in accordance with the plan of distribution set forth in the registration
statement within nine (9) months after the effective date of the registration
statement, then such shares shall be deemed not to have been registered
pursuant to Section 2 and shall remain Registrable Securities.

                 Nothing in this Agreement shall be deemed to require any
holder of Registrable Securities to exercise its rights of conversion with
respect to, or its rights to acquire, any Registrable Securities, either as a
condition to demanding or requesting registration hereunder or at any other
time.

         3.      Registration Procedures.  No later than the applicable date
referenced in Section 2 herein for registration of the Registrable Securities,
the Company shall register such Registrable Securities in accordance with the
intended method of disposition thereof and pursuant thereto the Company shall:

                 (a)      prepare and file with the Securities and Exchange
         Commission ("SEC") a registration statement on such form as the
         holders of a majority of the Registrable Securities shall specify and
         which the Company shall be permitted to use with respect to such
         Registrable Securities and use its best efforts to cause such
         registration statement to become effective (provided that before
         filing a registration statement or prospectus or any amendments or
         supplements thereto, the Company shall furnish to the counsel selected
         by the holders of a majority of the Registrable Securities copies of
         all such documents proposed to be filed a reasonable time prior to
         filing, which documents shall be subject to the review and comment of
         such counsel and the inclusion of such material as such counsel may
         reasonably request);

                 (b)      prepare and file with the SEC such amendments and
         supplements to such registration statement and the prospectus used in
         connection therewith as may be necessary to (i) keep such registration
         statement effective for a period of not less than nine (9) calendar
         months and (ii) comply with the provisions of the Act with respect to
         the disposition of all securities covered by such registration
         statement during such period in accordance with the intended methods
         of disposition by the sellers thereof set forth in such registration
         statement; 


                 (c)     furnish to each holder of Registrable Securities and
         the underwriters, if any, such number of copies of such registration
         statement, each amendment and supplement thereto, the prospectus
         included in such registration statement (including each preliminary
         prospectus) and such other documents as such holder may request in
         order to facilitate the disposition of the Registrable Securities
         owned by such holder;






                                 Page 3 of 13
<PAGE>   82
                 (d)      use its best efforts to register or qualify such
         Registrable Securities under such other securities or blue sky laws of
         such jurisdictions as any holder requests and do any and all other
         acts and things which may be reasonably necessary or advisable to
         enable such holder to consummate the disposition in such jurisdictions
         of the Registrable Securities owned by such holder (provided that the
         Company will not be required to (i) qualify generally to do business
         in any jurisdiction where it would not otherwise be required to
         qualify but for this subparagraph, (ii) subject itself to taxation in
         any such jurisdiction or (iii) consent to general service of process
         in any such jurisdiction);

                 (e)      notify each holder of such Registrable Securities, at
         any time when a prospectus relating thereto is required to be
         delivered under the Act, of the receipt by the Company of any
         notifications with respect to suspension of the qualification of the
         Registrable Securities for sale in any jurisdiction or the initiation
         or threatening of any proceeding for such purpose or of the happening
         of any event known to the Company as a result of which the prospectus
         included in such registration statement contains an untrue statement
         of a material fact or omits any material fact necessary to make the
         statements therein not misleading, and, at the request of any such
         holder, the Company shall prepare a supplement or amendment to such
         prospectus so that, as thereafter delivered to the purchasers of such
         Registrable Securities, such prospectus shall not contain an untrue
         statement of a material fact or omit to state any material fact
         necessary to make the statements therein not misleading;

                 (f)      cause all such Registrable Securities to be listed on
         each securities exchange or quoted on each interdealer quotation
         system on which similar securities issued by the Company are then
         listed or quoted, or if similar securities are not then listed or
         quoted, to cause such securities to become listed or quoted prior to
         the sale of Registrable Securities pursuant to the registration
         hereunder;

                 (g)      provide a transfer agent and registrar for all such
         Registrable Securities not later than the effective date of such
         registration statement and facilitate the timely preparation and
         delivery of certificates representing the Registrable Securities to be
         sold under the registration statement, in such denominations and
         registered in such names as the managing underwriter or underwriters,
         if any, or the holders of Registrable Securities may request;

                 (h)      enter into such customary and reasonable agreements
         (including underwriting agreements in customary and reasonable form)
         and take all such other actions as the holders of a majority of the
         Registrable Securities, or the underwriters, if any, reasonably
         request in order to expedite or facilitate the disposition of such
         Registrable Securities (including, without limitation, effecting a
         stock split or a combination of shares);


                 (i)     make available for inspection by any holder of
         Registrable Securities, any underwriter participating in any
         disposition pursuant to such registration statement, and any attorney,
         accountant or other agent retained by any such holder or underwriter,
         all financial and other records, pertinent corporate documents and
         properties of the Company as may be reasonably requested, and cause
         the Company's officers, directors, employees and independent
         accountants to supply all information reasonably requested by any such
         holder, underwriter, attorney, accountant or agent in connection with
         such registration statement;




                                 Page 4 of 13
<PAGE>   83
                 (j)      use its best efforts to cause such Registrable
         Securities covered by such registration statement to be registered
         with or approved by such other governmental agencies or authorities as
         may be reasonably necessary to enable the holders thereof to
         consummate the disposition of such Registrable Securities;

                 (k)      obtain for the benefit of the holders of Registrable
         Securities and the underwriters, if any, a comfort letter from the
         Company's independent public accountants and a legal opinion from the
         Company's counsel, each in customary and reasonable form and covering
         such matters of the type customarily and reasonably covered by comfort
         letters and legal opinions as the holders of a majority of the
         Registrable Securities reasonably request;

                 (l)      otherwise use its reasonable efforts to comply in all
         material respects with all applicable rules and regulations of the
         SEC, and make available to its security holders, as soon as reasonably
         practicable, an earnings statement covering the period of at least
         twelve (12) months beginning with the first month after the "effective
         date of the registration statement" (as determined in accordance with
         the provisions of Rule 158(c) of the Act), which earnings statement
         shall satisfy the provisions of Section 11(a) of the Act and Rule 158
         thereunder;

                 (m)      permit any holder of Registrable Securities which
         holder, in its sole and exclusive judgment, might be deemed to be an
         underwriter or a controlling person of the Company, to participate in
         the preparation of such registration or comparable statement and to
         require the insertion therein of material, furnished to the Company in
         writing, which in the reasonable judgment of such holder and its
         counsel should be included; and

                 (n)      in the event of the issuance of any stop order
         suspending the effectiveness of a registration statement, or of any
         order suspending or preventing the use of any related prospectus or
         suspending the qualification of any Registrable Securities included in
         such registration statement for sale in any jurisdiction, the Company
         will use its reasonable efforts promptly to obtain the withdrawal of
         such order.

If any such registration or comparable statement refers to any holder
of Registrable Securities by name or otherwise as the holder of any securities
of the Company and if in its sole and exclusive judgment, such holder is or
might be deemed to be a controlling person of the Company, such holder shall
have the right to require the insertion therein of language, in form and
substance satisfactory to such holder and presented to the Company in writing,
to the effect that the holding by such holder of such securities is not to be
construed as a recommendation by such holder of the investment quality of the
Company's securities covered thereby and that such holding does not imply that
such holder will assist in meeting any future financial requirements of the
Company.


         4.      Registration Expenses.  All expenses incident to the Company's
performance of or compliance with this Agreement, including without limitation
all registration and filing fees, fees and expenses of compliance with
securities or blue sky laws, printing expenses, messenger and delivery
expenses, and fees and disbursements of counsel for the Company and all
independent certified public accountants, underwriters (excluding discounts and
commissions) and other persons retained by the Company (all such expenses being
herein called "Registration Expenses"), shall be borne in their entirety by the
Company; provided, that the Company shall, in addition, pay its internal
expenses (including,



                                 Page 5 of 13
<PAGE>   84
without limitation, all salaries and expenses of its officers and
employees performing legal or accounting duties), the expense of any annual
audit or quarterly review, the expense of any liability insurance (relating
exclusively to any such liability insurance in effect as of the date hereof)
and the expenses and fees for listing the securities to be registered on each
securities exchange or interdealer quotation system on which similar securities
issued by the Company are then listed.

         5.      Indemnification.

                 (a)      The Company agrees to indemnify each holder of
         Registrable Securities covered by such registration statement, its
         officers, directors, partners, stockholders, employees, agents,
         trustees and each Person who controls such holder (within the meaning
         of the Act) against all losses, claims, damages, liabilities and
         expenses or amounts paid in settlement caused by (i) any violation or
         alleged violation of federal or state securities laws caused by the
         execution or implementation of this Agreement and (ii) any untrue or
         alleged untrue statement of material fact contained in any
         registration statement, prospectus or preliminary prospectus or any
         amendment thereof or supplement thereto or any omission or alleged
         omission of a material fact required to be stated therein or necessary
         to make the statements therein not misleading, except insofar as the
         same are caused by or contained in any information furnished in
         writing to the Company by such holder expressly for use therein or by
         such holder's failure to deliver a copy of the registration statement
         or prospectus or any amendments or supplements thereto after the
         Company has furnished such holder with sufficient number of copies of
         the same.  In connection with an underwritten offering, the Company
         will indemnify such underwriters, their officers and directors and
         each Person who controls such underwriters (within the meaning of the
         Act) to the same extent as provided above with respect to the
         indemnification of the holders of Registrable Securities.  The
         payments required by this Section 5(a) will be made periodically
         during the course of the investigation or defense, when and as bills
         are received or expenses incurred.

                 (b)      In connection with any registration statement in
         which a holder of Registrable Securities is participating, each such
         holder will furnish to the Company in writing such information and
         affidavits as the Company reasonably requests for use in connection
         with any such registration statement or prospectus and, to the extent
         permitted by law, will indemnify the Company, its director and
         officers and each person who controls the Company (within the meaning
         of the Securities Act) against any losses, claims, damages,
         liabilities and expenses resulting from any untrue or alleged untrue
         statement of material fact contained in the registration statement,
         prospectus or preliminary prospectus or any amendment thereof or
         supplement thereto, or any omission or alleged omission of a material
         fact required to be stated therein or necessary to make the statements
         therein not misleading, but only to the extent that such untrue
         statement or omission is contained in any information or affidavit so
         furnished in writing by such holder; provided that such obligation to
         indemnify will be several, not joint and several, among such holders
         of Registrable Securities and the liability of each such holder will
         be in proportion to and limited to the net amount received by such
         holder from the sale of Registrable Securities pursuant to such
         registration statement.

                 (c)      Any Person (an "Indemnified Person") entitled to
         indemnification hereunder will (i) give prompt written notice to the
         party against whom indemnification is sought (the "Indemnifying
         Person") of any claim with respect to which it seeks indemnification
         (but the


                                 Page 6 of 13
<PAGE>   85
         failure to provide such notice shall not release the Indemnifying 
         Person of its indemnification obligations hereunder, unless the 
         Indemnifying Person has been prejudiced by such failure to provide such
         notice and then only to the extent of such prejudice) and (ii) unless
         in such Indemnified Person's reasonable judgment, a conflict of 
         interest between such Indemnified Person and the Indemnifying Person 
         may exist with respect to such claim, permit the Indemnifying Person 
         to assume the defense of such claim with counsel reasonably 
         satisfactory to the Indemnified Person, provided that the Indemnifying
         Person does so diligently and in good faith.  If such  defense is
         assumed, the Indemnifying Person will not be subject to any liability
         for any settlement made by the Indemnified Person without the
         Indemnifying Person's consent (but such consent will not be
         unreasonably withheld).  An Indemnifying Person who is not entitled to,
         or elects not to, assume the defense of a claim will not be obligated
         to pay the fees and expenses of more than one (1) counsel for all
         parties indemnified by the Indemnifying Person with respect to such
         claim, unless in the reasonable judgment of any Indemnified Person, a
         conflict of interest may exist between such Indemnified Person and any
         other Indemnified Person with respect to such claim.

                 (d)      The indemnification provided for under this Agreement
         shall remain in full force and effect regardless of any investigation
         made by or on behalf of the indemnified party or any officer,
         director, shareholder or controlling person of such indemnified party
         and shall survive the transfer of securities.

                 (e)      The Company also agrees to make such provisions, as
         are reasonably requested by any indemnified party, for contribution to
         such party in the event the Company's indemnification is unavailable
         for any reason.

         6.      Selection of Underwriters.  The holders of a majority of the
Registrable Securities included in any registration shall have the right to
select the investment banker(s) and manager(s) to administer the offering,
subject to the Company's approval which will not be unreasonably withheld.

         7.      Participation in Underwritten Registrations.  No person may
participate in any registration hereunder which is underwritten unless such
person (a) agrees to sell such person's securities on the basis provided in any
underwriting arrangements reasonably suggested by the Company's underwriters
and (b) completes and executes all questionnaires, powers of attorney,
indemnities, underwriting agreements and other documents reasonably required
under the terms of such underwriting arrangements not inconsistent with this
Agreement. The provisions of this Section shall in no way limit any holders of
Registrable Securities rights pursuant to this Agreement to registration 
hereunder in a non-underwritten registration.

         8.      Priority on Demand Registrations.  The Company will not
include in any registration hereunder any securities which are not Registrable
Securities without the prior written consent of the holders of a majority of
the Registrable Securities included in such registration.  If a registration
hereunder is an underwritten offering and the managing underwriters advise the
Company in writing that in their opinion the number of Registrable Securities
and, if permitted hereunder, other securities requested to be included in such
offering exceeds the number of Registrable Securities and other securities, if
any, which can be sold in such offering, without adversely affecting the
marketability of the offering, the Company will include in such registration in
the case of a registration requested by the





                                 Page 7 of 13
<PAGE>   86
holders of a majority of the Registrable Securities, (x) first, the     
Registrable Securities requested to be included in such registration, (y)
second, other securities issued pursuant to the terms and provisions of the
Preferred Stock Purchase Agreement which the Other Stockholder requests to be
included in such registration, and (z) third, other securities requested to be
included in such registration.

Unless otherwise agreed by the Company, any Persons other than holders of
Registrable Securities who participate in Demand Registrations must pay their
share of the Registration Expenses as provided in Section 4.

         9.      Security Issuance, Other Registration Rights.  Except as
provided in this Agreement, the Convertible Debt Agreement, or the Preferred
Stock Purchase Agreement, the Company will not (i) issue or sell any of its
securities of any kind, (ii) register any of its securities for sale under the
Act or any state securities law or (iii) grant to any Persons the right to
request or require the Company to register any equity securities of the
Company, or any securities convertible or exchangeable into or exercisable for
such securities, without the prior written consent of the holders of a majority
of Registrable Securities; provided that the Company may grant rights to other
Persons to (i) participate in Piggyback Registrations so long as such rights
are subordinate to the rights of the holders of Registrable Securities with
respect to such Piggyback Registrations and (ii) request registrations so long
as the holders of Registrable Securities are entitled to participate in any
such registrations with such Persons pro rata on the basis of the number of
shares owned by each such holder and any such registration is subject to the
approval of the holders of a majority of the Registrable Securities.

         10.     Piggyback Registrations.

                 (a)      Right to Piggyback.  Whenever the Company proposes to
         register any of its securities under the Act (other than pursuant to a
         registration hereunder) as permitted by Section 9 and the registration
         form to be used may be used for the registration of Registrable
         Securities (a "Piggyback Registration"), the Company will give prompt
         written notice to all holders of Registrable Securities of its
         intention to effect such a registration at least thirty (30) days
         prior to the anticipated filing date of the registration statement
         relating to such registration.  Such notice will offer the holders of
         Registrable Securities the opportunity to include in such registration
         statement such Registrable Securities as each holder may request in
         writing within twenty (20) days after the receipt of the Company's
         notice.  Except as provided in paragraphs 10(c), 10(d) and 10(e) below,
         the Company shall include in any such registration statement all such
         Registrable Securities requested to be included.

                 (b)      Piggyback Expenses.  The Registration Expenses of the
         holders of Registrable Securities will be paid by the Company in all
         Piggyback Registrations.

                 (c)      Priority on Primary Registrations.  If a Piggyback
         Registration is an underwritten primary registration on behalf of the
         Company, and the managing underwriters advise the Company in writing
         that in their opinion the number of securities requested to be
         included in such registration exceeds the number which can be sold in
         such offering without adversely affecting the marketability of the
         offering, the Company will include in such registration (i) first, the
         securities the Company proposes to sell, (ii) second, the Registrable
         Securities requested to 



                                 Page 8 of 13
<PAGE>   87
         be included in such registration and (iii) third, other
         securities requested to be included in such registration.

                 (d)      Priority on Secondary Registrations.  Except as
         otherwise provided in Section 8 hereof, if a Piggyback Registration is
         an underwritten primary registration other than on behalf of the
         Company, and the managing underwriters advise the Company in writing
         that in their opinion the number of securities requested to be
         included in such registration exceeds the number which can be sold in
         such offering without adversely affecting the marketability of the
         offering, the Company will include in such registration the securities
         requested to be included in such registration reduced pro rata in
         accordance with the original number of securities requested to be
         included.

                 (e)      Withdrawal by Company.  If, at any time after giving
         written notice of its intention to register any of its securities as
         set forth in Section 10(a) and prior to the effective date of the
         registration statement filed in connection with such registration, the
         Company shall determine for any reason not to register such
         securities, the Company may, at its election, given written notice of
         such determination to each holder of Registrable Securities and
         thereupon shall be relieved of its obligation to register any
         Registrable Securities in connection with such registration (but not
         from its obligation to pay the Registration Expenses in connection
         therewith as provided herein).

         11.     Other Registrations.  If the Company has previously filed a
registration statement with respect to Registrable Securities pursuant to
Section 2 or Section 10, and if such previous registration has not been
withdrawn or abandoned, the Company will not file or cause to be effected any
other registration of any of its equity securities or securities convertible or
exchangeable into or exercisable for its equity securities under the Act
(except on Form S-8 or any successor form), whether on its own behalf or at the
request of any holder or holders of such securities, until a period of at least
nine (9) months has elapsed from the effective date of such previous
registration, unless a shorter period of time is approved by the holders of a
majority of Registrable Securities included in such registration.

         12.     Holdback Agreements.  Notwithstanding the provisions of
Section 9, the Company agrees (i) not to effect any public sale or distribution
of its equity securities, or any securities convertible into or exchangeable or
exercisable for such securities, during the thirty (30) days prior to and during
the 270-day period beginning on the effective date of any underwritten
registration hereunder or any underwritten Piggyback Registration (except as
part of such underwritten registration or pursuant to registrations on Form S-8
or any successor form), unless the underwriters managing the registered public
offering otherwise agree, and (ii) to cause each holder of at least 5% (on a
fully-diluted basis) of its Common Stock, or any securities convertible into or
exchangeable or exercisable for Common Stock, purchased from the Company at any
time after the date of this Agreement (other than in a registered public
offering) to agree not to effect any public sale or distribution (including
sales pursuant to Rule 144) of any such securities during such period (except as
part of such underwritten registration, if otherwise permitted), unless the
underwriters managing the registered public offering otherwise agree.




                                 Page 9 of 13
<PAGE>   88
         13.     Creditor Standstill.  During the 270-day period beginning on
the effective date of any underwritten registration pursuant to Section 2
hereof, the Stockholders shall not make any demands for registration pursuant
to Section 2 hereof.  During the 180-day period beginning on the effective date
of any underwritten registration pursuant to Section 2 of the Other
Registration Agreement, the Stockholders shall not make any demand for
registration pursuant to Section 2 hereof.

         14.     Stock Legends.  When and to the extent permitted by the Act,
the Company shall provide to the holders of Registrable Securities, at no cost
or expense to such holders, equivalent stock certificates without restrictive
legends of any kind to evidence that their shares of the Company's Common Stock
are not restricted securities under the Act.

         15.     Current Public Information.  The Company shall use its best
efforts to file the reports required to be filed by it under the Act and the
Securities Exchange Act of 1934, as amended, and the rules and regulations
promulgated thereunder, (or, if the Company is not required to file such
reports, it shall, upon the request of the holders of a majority of the
Registrable Securities, use its best efforts to make publicly available
sufficient information, for so long as necessary, to permit sales under Rule
144 under the Act), and it shall use its best efforts to take such further
action as the holders of a majority of the Registrable Securities may
reasonably request, all to the extent required from time to time to enable the
holders of a majority of the Registrable Securities to sell the Registrable
Securities, without registration under the Act within the limitation of the
exemptions provided by (a) Rule 144 under the Act, as such Rule may be amended
from time to time, or (b) any similar rule or regulation hereafter adopted by
the SEC.   Upon the request of the holders of a majority of the Registrable
Securities, the Company will deliver to the holders of a majority of the
Registrable Securities a written statement as to whether it has complied with
such requirements.

         16.     Miscellaneous.

                 (a)      Remedies.  Any person having rights under any
         provision of this Agreement shall be entitled to enforce such rights
         specifically, to recover damages caused by reason of any breach of any
         provision of this Agreement and to exercise all other rights granted
         by law.

                 (b)      Amendments and Waivers.  The Company may agree to an
         amendment of the provisions of this Agreement and the Company may take
         any action herein prohibited, or omit to perform any act herein
         required to be performed by it, only if the Company has obtained the
         written consent of holders of at least a majority of the Registrable
         Securities.

                 (c)      Successors and Assigns.  All covenants and agreements
         in this Agreement by or on behalf of any of the Parties shall bind and
         inure to the benefit of the respective successors and assigns of the
         Parties whether so expressed or not.

                 (d)      Notices.  Any notice provided for in this Agreement
         must be in writing and must be either personally delivered or by
         courier against written acknowledgment of receipt or mailed by
         registered mail, postage prepaid and return receipt requested, to the
         Company at Princeton Dental Management Corporation, 2358 Hassell Road,
         Hoffman Estates, Illinois 60195, and to the Stockholders at their
         respective business addresses provided by the Stockholders in the
         Purchase Agreement, or, if changed by a Stockholder hereafter by
         notice from such Stockholder



                                Page 10 of 13
<PAGE>   89
         to the Company in accordance with the provisions set forth
         herein, at said new address provided by such Stockholder to the
         Company.  Notice pursuant to this Section shall be deemed received on
         the date of delivery to the party receiving such notice as evidenced
         by the date set forth on the receipt signed by the party receiving
         such notice.

                 (e)      Governing Law.  All questions concerning the
         construction, validity and interpretation of this Agreement will be
         governed and controlled by the laws of the State of Illinois as to
         interpretation, enforcement, validity, construction, effect, choice of
         law, without giving effect to principles of conflicts of laws, and in
         all other respects. The Parties agree that all actions and proceedings
         in any way, manner or respect arising out of or from or related to
         this Agreement shall be litigated in courts having situs within the
         County of Cook, State of Illinois, and the Parties hereby covenant and
         submit to the jurisdiction of any local, state or federal court
         located within said county and state.

                 (f)      Severability.      If any provision of this Agreement
         is held to be invalid, illegal or unenforceable in any respect under
         applicable jurisdiction, such invalidity, illegality or
         unenforceability will not affect any other provision, but this
         Agreement will be deemed reformed, construed and enforced as if such
         invalid, illegal or unenforceable provision had never been contained
         herein.

                 (g)      Authorization.  Those persons signing on behalf of
         the Company have been duly authorized by the Company to execute this
         Agreement, and any related agreements between the Company and the
         Stockholders, the signatures of the undersigned are binding upon the
         Company, and their execution of this Agreement does not constitute a
         breach of any existing agreement to which the Company is a party.

                 (h)      Entire Agreement and Modification.  The Company and
         the Stockholders hereby represent and warrant that, except for the
         provisions of the Purchase Agreement and the Warrants (all of which
         are hereby incorporated herein and made a part hereof by these
         references thereto) this Agreement is intended to and does contain and
         embody all of the understandings and agreements, both written and
         oral, of the Parties with respect to the subject matter of this
         Agreement, and that there exists no oral agreement or understanding,
         express or implied, whereby the absolute, final and unconditional
         character and nature of this Agreement shall be in any way
         invalidated, empowered or affected.  A modification or waiver of any
         of the terms, conditions or provisions of this Agreement shall be
         effective only if made in writing and executed with the same formality
         as this Agreement.

Stock having a purchase price equal to 14.94253% of the amount requested under
this 



 

                                Page 13 of 56

Agreement, and if Borrower fails to so request such amount, such request shall
be automatically deemed to be made by Borrower under the Preferred Stock
Purchase Agreement.  Each request by Borrower and each advance by Lender under 
this Section 2.1 shall only be made upon the satisfaction of all the conditions
contained in this Agreement and shall be paid by wire transfer of immediately
available funds, in such account or accounts as Borrower may, from time to
time, designate in a notice to be delivered to Lender no later than seven (7)
Business Days prior to its effectiveness (the "Wire Transfer Instructions");
provided, however, that the making of an advance hereunder shall not be deemed
to be an acknowledgment by Lender that any of the conditions contained in this
Agreement have been satisfied.  The indebtedness of Borrower pursuant 
to each advance under this Section 2.1 shall be evidenced by a Convertible
Secured Note in form attached hereto as Exhibit B, with appropriate insertions,
dated the Closing Date and payable to the order of the Lender in the principal
amount of Thirteen Million Fifty Thousand and 00/100 dollars ($13,050,000.00). 
The date and amount of each advance made by the Lender to Borrower and of each
repayment of principal thereon received by the Lender shall be recorded by the
Lender in its records.  The aggregate unpaid principal amount so recorded shall
be presumptive evidence of the Principal amount owing and unpaid on such
Convertible Secure Note subject only to manifest error.  The failure so to
record any such amount or any error in so recording any such amount, however,
shall not limit or otherwise affect Borrower's obligations hereunder or under
any Convertible Secured Note to repay the principal amount of the Convertible
Loan made to or for the account of such Borrower, together with all interest
accruing thereon.  The Convertible Loan shall be due and payable upon the
earlier of (A) the Maturity Date and (B) the acceleration of the liabilities. 
Borrower agrees that if at any time the Indebtedness under the Convertible Loan
exceeds the Maximum Facility, Borrower shall promptly pay the Lender such
amount as is necessary to eliminate such excess.  The principal amount of the
convertible Loan may not be paid or prepaid except in accordance with and to
the extent permitted under Article 10.  Once Called Debt is Called in
accordance with Article 10, it may not be reborrowed.

        2.2.     Initial Convertible Loan.  Upon Borrower's execution of this
Agreement, the Existing Amsterdam Indebtedness presently owed by borrower to
Lender as evidenced by the Secured Revolving Demand Note (the "Initial
Principal Amount") shall be deemed to be an advance under the Convertible Loan
(the "Initial Convertible Loan") and shall be re-evidenced by the Convertible
Secured Note.  The Convertible Secured Note shall be an amendment and
restatement of the Secured Revolving Demand Note and shall continue to be
secured pursuant to the provisions of the Collateral Documents, as amended and
restated by the Security Agreement.  The amounts owed under the Initial
Convertible Loan shall be deemed to be a portion of and shall be subject to all
of the other rights and obligations applicable to a Convertible Loan made by
the Lender to Borrower pursuant to Section 2.1 hereof.

         2.3.    Conditions of Advances.  Notwithstanding any other provisions
contained in this Agreement, the making of any advance provided for in this
Agreement shall be conditioned upon each of the following:

                 2.3.1  Borrowing Request.  Borrower shall provide the Lender
         an irrevocable borrowing request not later than 10:00 a.m.  Chicago
         time on the date 30 Business Days' prior to the 
 

                                Page 14 of 56
<PAGE>   15

         proposed borrowing date (which must be a Business Day) of each 
         borrowing under the Convertible Loan facility.  Each borrowing request
         shall be in an amount of not less than $50,000.00.  If in its Sole and
         Exclusive Discretion Lender agrees to make an advance to Borrower
         hereunder on less than 30 Business Days' prior notice by Borrower,
         Borrower shall pay Lender a fee equal to 2.5% of the amount advanced,
         which may be deducted from the amount advanced.  Such borrowing notice
         must be made in writing by an Authorized Representative pursuant to
         Section 13.2 hereof, and shall specify the requested amount and
         borrowing date of the Convertible Loan.  Any such borrowing request
         which the Lender believes to come from an Authorized Representative
         shall be irrevocable and binding on Borrower.  Before 10:00 a.m.
         Chicago time on the requested borrowing date Borrower shall deliver to
         the Lender a duly executed and completed Convertible Loan Request
         Certificate, in the form attached hereto as Exhibit C, specifying the
         requested borrowing date and amount of the Convertible Loan, and
         containing a certification by an Authorized Representative on behalf
         of Borrower, in form and substance satisfactory to the Lender, that
         prior to and after giving effect to the requested borrowing under the
         Convertible Loan,  Borrower is and will be in compliance with the
         terms and conditions of this  Agreement, that no Default does or will
         exist hereunder, that all of the  representations and warranties
         contained in this Agreement shall be true and  correct as of the date
         the request for the borrowing under the Convertible Loan is made.

                 2.3.2.   Financial Condition.  No material adverse change, as
         determined by the Lender in its Sole and Exclusive Discretion, in the
         financial condition or operations of Borrower or its Subsidiaries
         shall have occurred at any time or times subsequent to the most recent
         Financial Statements provided pursuant to Section 8.1.1 of this
         Agreement.

                 2.3.3.   No Default.  No Default shall have occurred and be
         continuing.

                 2.3.4.   Other Requirements.  The Lender shall have received,
         in form and substance satisfactory to the Lender in its Sole and
         Exclusive Discretion, all certificates, orders, authorities, consents,
         affidavits, schedules, instruments, security agreements, financing
         statements, mortgages and other documents which are provided for
         hereunder, or which the Lender may at any time reasonably request.

                 2.3.5.   Representations and Warranties.  All of the
         representations and warranties contained in this Agreement and in the
         other Loan Documents shall be true and correct as of the date the
         request for the Convertible Loan is made, and as of the date the
         advance thereunder is made, as though made on and as of such date.

                 2.3.6.   Lender's Sole and Exclusive Discretion.  The Lender
         shall have determined in its Sole and Exclusive Discretion that it
         desires to make the requested advance, it being understood that Lender
         has absolutely no obligation under any circumstance to make any such
         advance.

         2.4.    Maturity Date.




 

                                          Page 15 of 56

                2.4.1.   Unless otherwise accelerated in accordance with the
         provisions hereof, the Convertible Loan and the Convertible Secured
         Notes issued pursuant to this Agreement will mature on the Maturity
         Date.  On or before 10:00 a.m. (Nassau, Bahamas time) on the Maturity
         Date, Borrower shall pay, and Lender shall receive notice of receipt
         thereof from Lender's correspondent U.S. bank, by wire transfer of
         immediately available funds in United States dollars, the then
         outstanding principal amount of the Convertible Secured Notes plus any
         then unpaid interest or fees due on the Convertible Secured Notes to
         the holders of the Convertible Secured Notes for immediate credit
         pursuant to wiring instructions which Borrower will obtain from the
         Lender, or, at the election of the Lender, by certified check or
         cashier's check to each holder at its address or addresses referred to
         in Section 13.2 of this Agreement or at such other address as Lender
         may specify by written notice to Borrower.  No payment shall be deemed
         made until good funds are received by Lender.

         2.5.    Interest on the Convertible Secured Notes.  Borrower shall pay
interest on the unpaid principal amount of the Convertible Secured Notes from
the issuance date of the applicable Convertible Secured Note until such
principal amount shall be paid in full, at a rate equal to the Stated Rate,
payable in accordance with Section 2.6 of this Agreement; provided, however,
that, upon the occurrence of a Payment Event of Default, the unpaid principal
amount of the Convertible Secured Notes together with accrued interest thereon
and any other Liabilities then outstanding shall bear interest from the date on
which such amount is due until the date on which such amount is paid in full or
such Payment Event of Default is otherwise cured or waived by the Lender in its
Sole and Exclusive Discretion, payable on demand, at a rate equal to the
Default Rate.  Interest which is not paid when due shall bear interest at the
Default Rate from the date on which such interest is due until the date on
which such interest is paid in full.

         2.6     Payments and Computations.  All computations of interest under
the Convertible Secured Notes shall be made by Lender on the basis of a year of
360 days for the actual number of days (determined in accordance with Section
1.4 hereof) occurring in the period for which such interest is payable.  Except
as otherwise specifically provided, all interest to be paid under the
Convertible Secured Notes shall be paid quarterly in arrears on the last
Business Day of March, June, September and December of each calendar year
beginning with June, 1996.

         2.7.    Payment on Non-Business Days.  Whenever any payment to be made
hereunder or under the Convertible Secured Notes shall be stated to be due on
any day other than a Business Day, such payment may be made on the next
succeeding Business Day, and such extension of time shall in such case be added
to the time period and, thereby, included in the computation of interest due on
such date.

         2.8.    Use of Proceeds.  Borrower agrees that the proceeds of the
Convertible Secured Notes shall be used only for the purpose of (i) paying
related fees and expenses incurred in connection therewith and herewith, (ii)
for working capital purposes, and (iii) as otherwise specifically permitted in
writing by Lender.


 

                                Page 16 of 56
<PAGE>   17
         2.9.    Fee.  Borrower hereby agrees to pay to Lender, upon the
execution of this Agreement, a fee in the amount of $261,000.00, which fee
shall be deemed to be an advance under the Convertible Loan, as if Lender had
advanced said sum on the Closing Date, and shall be evidenced by a Convertible
Secured Note dated as of the Closing Date and delivered to Lender upon the
execution of this Agreement.

         2.10    Registration of Transfer and Exchange of Convertible Secured
Notes.

         Borrower shall maintain at its office in Hoffman Estates, Illinois, or
at its designated agent, a register ("Register") in which, subject to such
reasonable regulations as it or Lender may prescribe, Borrower shall provide
for the registration of Convertible Secured Notes and of transfers and
exchanges of Convertible Secured Notes as herein provided.

         The Convertible Secured Notes have not been registered or qualified
under the Securities Act or any state securities laws.  No transfer, sale,
pledge or other disposition of any Convertible Secured Note shall be made
unless that disposition is made pursuant to an effective registration statement
under the Securities Act and effective registration or qualification under
applicable state securities laws, or is made in a transaction which does not
require such registration or qualification.  In the event that a disposition is
to be made without registration or qualification, Borrower may require, in
order to assure compliance with such laws, that the holder of a Convertible
Secured Note desiring to effect the disposition, and the prospective
transferee, represent and warrant to Borrower in writing, the facts surrounding
the disposition.  In the event that such representation and warranty of facts
does not on its face establish that registration or qualification is not
required, Borrower may require an opinion of counsel reasonably satisfactory to
it that the disposition may be made without such registration or qualification.
Any such opinion of counsel shall be an expense of Borrower.  Borrower is not
obligated to register or qualify the Convertible Secured Notes under the
Securities Act or any other securities law or to take any action not otherwise
required under this Agreement to permit the disposition of the Convertible
Secured Notes without registration or qualification.

         Subject to the preceding paragraphs, upon surrender for registration
or transfer of any Convertible Secured Note to Borrower, Borrower shall execute
in the name of the designated transferee or transferees, one or more new
Convertible Secured Notes in the same aggregate principal amount of the
surrendered Convertible Secured Note and dated the date to which interest shall
have been paid thereon.  Borrower shall reflect such transfer on the Register.

         All Convertible Secured Notes surrendered for transfer and exchange
shall be destroyed by Borrower upon issuance of the new Convertible Secured
Notes applicable thereto.

         2.11    Mutilated, Destroyed, Lost or Stolen Convertible Secured Note.
 
         If any mutilated Convertible Secured Note is surrendered to Borrower,
or Borrower receives evidence to its reasonable satisfaction (an affidavit of
the Lender shall be deemed satisfactory) of the



 

                                          Page 17 of 56
<PAGE>   18
destruction, loss or theft of any Convertible Secured Note then, in the
absence of actual notice to Borrower that such Convertible Secured Note has
been acquired by a bona fide purchaser, the Borrower shall execute and Borrower
shall deliver, in exchange for or in lieu of such mutilated, destroyed, lost or
stolen Convertible Secured Note, a new Convertible Secured Note in the same
principal amount as the such mutilated, destroyed, lost or stolen Convertible
Secured Note.  Any duplicate Convertible Secured Note issued pursuant to this
Section 2.11 shall constitute complete and indefeasible evidence of ownership
of the Convertible Secured Note, as if originally issued, whether or not the
mutilated, destroyed, lost or stolen Convertible Secured Note shall be found at
any time.

         2.12    Persons Deemed Owners.

         Prior to due presentation of a Convertible Secured Note for
registration of transfer, the Borrower shall treat the person in whose name the
Convertible Secured Note is registered as the owner of such Convertible Secured
Note for all purposes and the Borrower shall not be affected by knowledge or
notice to the contrary.

 
                                  ARTICLE III

                    CONVERSION OF CONVERTIBLE SECURED NOTES


         3.1.    Conversion.  The holder of a Convertible Secured Note shall
have the following conversion rights:

                 3.1.1.   Conversion Right.  Subject to the terms and
         conditions of this Section 3.1, the holders of Convertible Secured
         Notes shall have the right, at their option, to convert the
         outstanding principal owed and any other Liabilities (excluding
         contingent Liabilities the amount of which are not reasonably
         ascertainable) (the "Total Convertible Amount") under their
         Convertible Secured Notes or any portion thereof into Shares (with
         full voting rights no less than those of any other Shares) as follows:

                          (a)     The conversion rights provided for in this
                 Article 3 shall be exercisable at any time or from time to
                 time (whether before or after an Event of Default,
                 acceleration or other demand for payment) prior to the payment
                 in full of the Convertible Secured Notes and any other
                 Liabilities thereunder in accordance with the terms of this
                 Agreement.



                          (b)     For the purpose of determining under this
                 Article 3 the number of Shares into which the Total
                 Convertible Amount of the Convertible Secured Notes may be
                 converted, the purchase price of and any other Liabilities
                 under the Preferred Stock issued pursuant to the Preferred
                 Stock Purchase Agreement shall

<PAGE>   19
                 be deemed to be included in the Total Convertible
                 Amount owed under Convertible Secured Notes (unless otherwise
                 required by the context), the outstanding principal amounts
                 owed under the Convertible Secured Notes shall be deemed
                 advanced on the date such funds are received by Borrower, and
                 the balance of the Total Convertible Amount under the
                 Convertible Secured Notes shall be deemed advanced on the date
                 that the Lender notifies Borrower that it desires to convert
                 such amounts pursuant to the provisions of this Article 3;

                        (c)     The Lender and the holders of the Preferred
                 Stock shall be entitled to convert the Total Convertible
                 Amount represented by such Convertible Secured Notes and
                 Preferred Stock based on the following formula:  (i)  Every
                 one dollar of Total Convertible Amount through and including
                 One Million Five Hundred Thousand dollars ($1,500,000.00)
                 shall be directly convertible into Shares representing 0.0018
                 percent of the Fully Diluted Shares with the result that, in
                 the instance of the issuance of One Million Five Hundred
                 Thousand dollars ($1,500,000.00) of Total Convertible Amount
                 and upon the conversion thereof into Shares, the holder
                 thereof shall own twenty-seven percent (27%) of the Fully

                 instance of the issuance of Four Million Five Hundred Thousand
                 dollars ($4,500,000.00) of Total Convertible Amount and upon

                 Four Million Five Hundred Thousand dollars ($4,500,000.00)
                 through and including Eight Million dollars ($8,000,000.00)

                 (75.001%) of the Fully Diluted Shares ((.000018 X
                 $1,500,000.00 = 27%) + (.0000108333333 X $1,500,000.00 =

                        Solely for the purposes of clarification and without 
                 limiting the immediately preceding paragraph in any fashion and
                 assuming that Borrower has 12,200,000 outstanding Shares on a
                 fully diluted basis, each One dollar ($1.00) of Total
                 Convertible Amount shall be convertible into Shares as follows:

                 Convertible Amount through and including One Million Five

                 subsection 3.1.1(c)(i) shall be directly convertible into a
                 number of Shares on a pro-rata basis, assuming that, for the
                 purposes of such pro-ration, in the instance of the issuance of
                 One Million Five Hundred Thousand dollars ($1,500,000.00) of
                 Total Convertible Amount and upon the conversion thereof into
                 Shares, the holder thereof shall own 4,512,329 Shares, i.e.

         the issuance of Four Million Five Hundred Thousand dollars
         ($4,500,000.00) of Total Convertible Amount and upon the conversion
         thereof into Shares, the holder thereof shall own 13,757,447 Shares,

         .53(25,957,447) = 13,757,447 Shares; (d) each and every States dollar
         ($1.00) of Total Convertible Amount above Four Million Five Hundred
         Thousand dollars ($4,500,000.00) through and including Eight Million
         dollars ($8,000,000.00) converted pursuant to subsection 3.1.1(c)(iv)

         Total Convertible Amount and upon the conversion thereof into Shares,
         the holder thereof shall own 21,689,360 Shares, i.e. (1.00 -.640005)X

                 ($15,000,000.00) converted pursuant to subsection 3.1.1(c)(vi)
                 shall be directly convertible into a number of Shares on a
                 pro-rata basis, assuming that, for the purposes of such
                 pro-ration, in the instance of the issuance of Fifteen Million
                 dollars ($15,000,000.00) of Total Convertible Amount and upon
                 the conversion thereof into Shares, the holder thereof shall
                 own 36,601,952 Shares, i.e. (1.00 - .75001)X = 12,200,000,

                 36,601,952 Shares;

                          Each holder of Convertible Secured Notes and
                 Preferred Stock shall be entitled to receive upon conversion
                 thereof that portion of the Fully Diluted Shares issuable
                 under each of the applicable subsections (i) through (vi) of
                 the first paragraph of this Section 3.1.1(c) which is equal to
                 a fraction (a) of which the numerator is the Total Convertible
                 Amount represented by the Convertible Secured Notes and
                 Preferred Stock held by such holder immediately prior to such
                 conversion and (b) of which the denominator is the Total
                 Convertible Amount represented by the Convertible Secured
                 Notes and Preferred Stock held by all holders of Convertible
                 Secured Notes and Preferred Stock immediately prior to such
                 conversion;

                          (d)     Such rights of conversion shall be exercised
                 by Lender (if Lender is then a holder of a Convertible Secured
                 Note) or by the holders of a majority of the Indebtedness
                 evidenced by the Convertible Secured Notes by giving written
                 notice to Borrower in the form attached as Exhibit D hereto
                 that such holder elects to convert the stated portion of the
                 Total Convertible Amount, as well as the portions of the
                 outstanding principal and the other Liabilities under the
                 Convertible Secured Note which are being converted and if (but
                 only if) the entire principal amount thereof is being
                 converted, surrendering such Convertible Secured Note to
                 Agent, to be held in escrow to be delivered in accordance with
                 Section 3.1.1.(e) hereof.  The exercise of such right of
                 conversion terminates and supersedes any right of Borrower to
                 repay the Convertible Secured Notes being so converted.  For
                 convenience, the conversion of any portion of the principal
                 amount of a Convertible Secured Note into Shares is
                 hereinafter sometimes referred to as the "conversion" of a
                 Convertible Secured Note; and

                          (e)      Not later than ten Business Days after the
                 receipt of the written notice referred to in Section 3.1.1(d),
                 and (if applicable) surrender of the Convertible Secured Note
                 for conversion, Borrower shall issue in the name of Lender and
                 deliver to Lender (or, if the Convertible Secured Note is
                 being surrendered for conversion, to Agent) a certificate or
                 certificates for the number of Shares issuable upon the
                 conversion in the name of the then registered

                          holder of the Convertible Secured Note.
                          Such conversion shall be deemed to have been effected
                          as of the start of business on the date such written
                          notice shall have been received by Borrower pursuant
                          to Section 13.2 of this Agreement (the "Conversion
                          Date"), and (if applicable) the Convertible Secured
                          Note shall have been surrendered for conversion as
                          aforesaid, and at such time the Person in whose name
                          or names any certificate or certificates for Shares
                          shall be issuable upon such conversion shall be
                          deemed to have become at such time the holder or
                          holders of record of the Shares represented thereby.
                          In the event that only a portion of a Convertible
                          Secured Note is converted, Lender shall record in its
                          records as a repayment of principal the amount equal
                          to the converted portion of the Convertible Secured
                          Note.  In the event the entire principal amount of a
                          Convertible Secured Note is converted, the holder
                          shall surrender its Convertible Secured Note
                          accompanied by a written instrument(s) of transfer in
                          the form attached hereto as Exhibit K, duly executed
                          by the holder to Agent.  Upon receipt by Agent of the
                          Shares issuable upon conversion and the original
                          Convertible Secured Note, if applicable, Agent shall
                          deliver to Borrower for cancellation the original
                          Convertible Secured Note, if applicable, and shall
                          deliver to the holder of the converted Convertible
                          Secured Note such Shares.

                   3.1.2.   Reservation.  Borrower will at all times reserve 
         and keep available such number of authorized Shares, solely for the
         purpose of issue upon the exercise of the conversion rights
         represented by the Convertible Secured Notes as herein provided for
         and the conversion rights pursuant to the Preferred Stock Purchase
         Agreement, as may at any time be issuable (based upon the number of
         Shares outstanding at any such time) upon the conversion of such
         Convertible Secured Notes and the conversion of any Preferred Stock
         issued pursuant to the Preferred Stock Purchase Agreement, and such
         Shares issuable upon the exercise of the conversion rights under the
         Convertible Secured Notes and the conversion of any Preferred Stock
         issued pursuant to the Preferred Stock Purchase Agreement shall at no
         time have an aggregate par value which is in excess of the portion of
         the Total Convertible Amount that will be converted into one Share
         upon the conversion of the Convertible Secured Note and the conversion
         of any Preferred Stock issued pursuant to the Preferred Stock Purchase
         Agreement.   

                 Notwithstanding the foregoing, Borrower and Lender acknowledge
         that as of the Closing Date, Borrower has 16,880,130 authorized Shares
         available for the purpose of issue upon the exercise of the conversion
         rights represented by the Convertible Secured Notes and the conversion
         rights provisions of the Preferred Stock issued pursuant to the
         Preferred Stock Purchase Agreement.  Based on Borrower's
         representation that there are 13,493,205 Fully Diluted Shares, the
         16,880,130 Shares available for issue upon the exercise of conversion
         rights described in the previous sentence may be issued in exchange
         for approximately $4,508,234 of the Total Convertible Amount
         represented by the Convertible Secured Notes and the Preferred      



 

                                Page 23 of 56

         Stock issued pursuant to the Preferred Stock Purchase Agreement.  If
         the Total Convertible Amount of the Convertible Secured Notes and the
         Preferred Stock issued pursuant to the terms and provisions of the
         Preferred Stock Purchase Agreement rises above said amount, and if
         Lender or any holder of Preferred Stock exercises its conversion
         rights with respect to the Convertible Secured Notes or the Preferred
         Stock issued pursuant to the terms and provisions of the Preferred
         Stock Purchase Agreement, or Borrower otherwise issues additional
         Shares, then unless additional Shares have been authorized, the Lender
         would be unable to effect the conversion of the total amount of
         Convertible Secured Notes or the Preferred Stock issued pursuant to
         the terms and provisions of the Preferred Stock Purchase Agreement. 
         In such an event, Borrower will take all actions necessary to increase
         the number of its authorized Shares in an amount sufficient to issue
         all Shares issuable upon the exercise of the conversion rights
         represented by the Convertible Secured Notes and the Preferred Stock
         issued pursuant to the Preferred Stock Purchase Agreement and, to the
         extent that approval of the stockholders of Borrower is required for
         such increase, will use its best efforts to secure such approval. 
         Furthermore, in the event that there are insufficient authorized
         Shares, Borrower will not issue or commit to issue any Shares other
         than pursuant to the conversion of Convertible Secured Notes pursuant
         to this Article 3 and pursuant to the exercise of the conversion
         rights pursuant to the Preferred Stock Purchase Agreement until a
         sufficient number of Shares are authorized.

                3.1.3.   Mergers, Consolidations, Sales.  In the case of any
         consolidation or merger of Borrower with another entity, or the sale
         of all or substantially all of its assets to another entity, or any
         reorganization or reclassification of the Shares or other equity
         securities of Borrower, then, as a condition of such consolidation,
         merger, sale, reorganization or reclassification, lawful and adequate
         provision shall be made whereby the holder of the Convertible Secured
         Notes shall thereafter have the right to receive upon the basis and
         upon the terms and conditions specified herein and in lieu of the
         Shares that theretofore would have been received upon conversion of
         the Convertible Secured Notes, such shares of stock, securities or
         assets as may be (by virtue of such consolidation, merger, sale,
         reorganization or reclassification) issued or payable with respect to
         or in exchange for a number of outstanding Shares equal to the number
         of Shares immediately theretofore so purchasable by conversion
         hereunder had such consolidation, merger, sale, reorganization or
         reclassification not taken place, and in any such case appropriate
         provisions shall be made with respect to the rights and interests of
         the holder of the Convertible Secured Notes to the end that the
         provisions hereof shall thereafter be applicable, as nearly as may be,
         in relation to any shares of stock, securities or assets thereafter
         deliverable upon exercise of the Convertible Secured Notes.  Borrower
         shall not effect any such consolidation, merger or sale, unless prior
         to or simultaneously with the consummation thereof, the successor
         entity (if other than Borrower) resulting from such consolidation or
         merger or the entity purchasing such assets shall assume by written
         instrument executed and mailed or delivered to the holder of the
         Convertible Secured Notes, the obligation to deliver to such holder
         such shares of stock, securities or assets as, in accordance with the
         foregoing provisions, such holder may be entitled to receive.  Nothing
         contained in this Section 3.1.3 shall permit Borrower to take any
         action or 





 

                                          Page 24 of 56

         enter into any transaction which is prevented or prohibited by
         any other provision of this Agreement or the other Loan Documents.

                   3.1.4.   Dissolution or Liquidation.  In the event of any
         proposed distribution of the assets of Borrower in complete
         dissolution or liquidation except under circumstances when the
         foregoing Section 3.1.3 shall be applicable, Borrower shall give
         notice thereof to the holders of the Convertible Secured Notes and
         shall make no distribution to shareholders until the expiration of 120
         days from the date of giving of the aforesaid notice and, in any such
         case, the holder of the Convertible Secured Notes may exercise the
         conversion rights with respect to the Convertible Secured Notes within
         120 days from the date of giving such notice and, upon the timely
         completion of such distribution or liquidation, all conversion rights
         herein granted not so exercised within such 120-day period shall
         thereafter become null and void.

                   3.1.5.   Notice of Dividends.  If the Board of Directors of
         Borrower shall declare any dividend or other distribution on the
         Shares, Borrower shall give notice thereof to the holder of the
         Convertible Secured Notes not less than 120 days prior to the record
         date fixed for determining shareholders entitled to participate in
         such dividend or other distribution and the holder of the Convertible
         Secured Notes shall not participate in such dividend or other
         distribution or be entitled to any rights on account or as a result
         thereof except to the extent that the conversion rights under the
         Convertible Secured Notes are exercised prior to such record date.
         The provisions of this section shall not apply to distributions made
         in connection with transactions covered by Section 3.1.3.

                   3.1.6.   Fractional Shares.  Fractional Shares may be issued
         upon the exercise of the Convertible Secured Notes in any case where
         the holder hereof would be entitled to receive a fractional Share upon
         the exercise of the Convertible Secured Notes in order to receive the
         appropriate percentage of Fully Diluted Shares; provided, that at its
         election, any holder may elect to receive in lieu of any fractional
         Share that it would otherwise receive cash in the amount of such
         fraction of the fair market value of a Share.


                   3.1.7.  Fully Paid Stock; Taxes.  Borrower covenants
         and agrees that the shares of stock represented by each and every
         certificate for Shares to be delivered on the exercise of the
         conversion rights herein provided for shall, at the time of such
         delivery, be validly issued and outstanding and be fully paid and

         Non-U.S. Person, but not including other income taxes) which may be
         payable in respect of the exercise of conversion rights by holders of

                                   ARTICLE VI

                         REPRESENTATIONS AND WARRANTIES


         As of the Closing Date, each date a request for the Convertible Loan
is made and each date an advance thereunder is made, Borrower represents and
warrants to Lender that, except as specifically and fairly disclosed in
Borrower's Annual Report on Form 10-K for its fiscal year ended December 31,
1994 and its Quarterly Reports on Form 10-Q for its quarters ended September
30, 1995 or in a schedule specifically referred to herein:

formed, validly existing and in good standing in the jurisdiction of
its formation, and has all powers and all governmental licenses,
authorizations, consents and approvals required to carry on its business as now
conducted and as proposed to be conducted, except where the failure to do any
of the above could not, singly or in the aggregate, reasonably be expected to
have a Material Adverse Effect and (b) duly qualified and authorized to do
business and in good standing in all jurisdictions where the failure to do so

Adverse Effect.

         6.2.    Subsidiaries.  Each Subsidiary of Borrower is (a) a

and authorized to do business and in good standing in all jurisdictions where
the failure to do so could, singly or in the aggregate, reasonably be expected
to have a Material Adverse Effect.

         6.3.    Authority, Execution, Delivery and Enforceability.  Borrower

the execution, delivery and performance of the Loan Documents to which it is a
party, and any other documents related thereto.  The Loan Documents to which
each Subsidiary of Borrower is a party are (or, when duly executed and
delivered will be) the legal, valid, and binding obligations of such
Subsidiary, enforceable against such Subsidiary in accordance with their
respective terms.

         6.5.    No Conflicts.  Neither the execution, delivery or performance
by Borrower of this Agreement, the other Loan Documents to which it is
a party, and any other documents related thereto nor the compliance by Borrower
with any of its obligations thereunder, nor the consummation of any of the
transactions contemplated thereby will (i) conflict with the Certificate of
Incorporation or the By-laws of Borrower or any Subsidiary or (ii) conflict
with or result in a breach of, or constitute a default under, or result in the
creation or imposition of, any Lien upon any of Borrower's or its Subsidiaries'
property or assets under (a) any indenture, mortgage, deed of trust or other
instrument or agreement (other than the Security Agreement) to which Borrower
or its Subsidiaries may be or become bound or to which any of Borrower's
property or assets may be or become subject or (b) any applicable law, rule,

         6.7.    No Consents.  No order, license, consent, authorization or
approval of, or exception by, or notice to or registration with, any
Governmental Authority or any other Person, and no filing, recording,
publication or registration of any kind, is necessary or advisable in

Subsidiaries of this Agreement or the Loan Documents or for the legality,
validity, binding effect or enforceability thereof.

         6.9.    Financial Matters.  All financial information heretofore or
contemporaneously furnished by or on behalf of Borrower, and all other such
information hereafter furnished by or on behalf of Borrower to Lender will be,
correct and complete in all material respects on the date as of which such
information is dated or certified (except for any projections included therein,
which projections shall have provided reasonable estimations of future
performance for the periods covered thereby based on assumptions which are
reasonable when made, subject to the uncertainty and approximation inherent in
any projections) and fairly present or will fairly present the financial
condition, results of operations and cash flows of Borrower and its
Subsidiaries, as applicable, in accordance with GAAP and without omitting
anything necessary to make such information not misleading at such time.

         6.10.   Representations and Warranties in Other Agreements.  There
have been delivered to Lender complete and correct copies of each of Borrower
Transaction Documents, as amended to the date hereof, and all exhibits and
schedules delivered in connection therewith.  The terms of each of Borrower
Transaction Documents have not changed in any material respect from the terms
reflected in the copies thereof delivered to Lender on or before the date of
this Agreement.  Each of the representations and warranties given by Borrower
or its Subsidiaries, and the other parties to such agreements in such documents
were true and correct in all material respects as of the date made and on the

returns and all other tax returns and reports, domestic and foreign, required
to be filed by it and has paid all taxes, assessments, fees and other
governmental charges payable by it which have become due, other than those not
yet delinquent or those which in the aggregate (including all fees and
penalties associated therewith) do not exceed $5,000.00.  Borrower and each of
its Subsidiaries has paid, or has provided adequate reserves for the payment
of, all federal, state and foreign income taxes applicable for all prior fiscal
years and for the current fiscal year to the date hereof.  There is no proposed
tax assessment against Borrower or against any of its Subsidiaries which, if
the assessment were made, could, singly or in the aggregate, reasonably be
expected to have a Material Adverse Effect.

         6.12.   Litigation and Adverse Facts.  Except as set forth in Schedule
6.12, there is no claim, action, suit, proceeding, investigation or
administrative proceeding or arbitration by any Governmental Authority or other
Person (including, without limitation, derivative actions) pending or known by
Borrower to be threatened with respect to Borrower, any of its Subsidiaries, or
any of its Affiliates or assets of any of the foregoing, or any officer,
director or other person who would be entitled to be indemnified by Borrower or
any Subsidiary, or any of the transactions contemplated hereby which could,
singly or in the aggregate, reasonably be expected to have a Material Adverse
Effect and there is no basis for such action, suit, proceeding, investigation
or arbitration and there has occurred no development in any action, suit,
proceeding, investigation or arbitration previously disclosed to Lender, which
could, singly or in the aggregate, reasonably be expected to have a Material
Adverse Effect



 

                                Page 31 of 56
<PAGE>   32

         6.13.   [Intentionally omitted.]

         6.14.   No Defaults.  Except as set forth on Schedule 6.14, there does
not exist (i) any event of default, or any event that with notice or lapse of
time or both would constitute an event of default, under any agreement or
obligation of Borrower or its Subsidiaries, including, without limitation: (a)
Borrower Transaction Documents or (b) any mortgage, deed of trust, indenture or
other instrument or agreement to which Borrower is a party or by which Borrower
may be bound or any of its property or assets may be subject which, in either
clause (a) or (b) above, would have a Material Adverse Effect, or (ii) any
Unmatured Event of Default.

         6.15.   Capitalization.  Since July 7, 1994, except as provided in
Schedule 6.15, Borrower has not offered, placed or sold, or caused to
be offered, placed or sold, any securities or other obligations.  Except for
Shares which may be issued pursuant to this Agreement, the Warrant, the
Preferred Stock Purchase Agreement or the Other Warrant, immediately after the
Closing Date, Borrower will have no more than 13,493,205 Fully Diluted Shares
(including all Shares issuable at any time upon the conversion, exercise or
exchange of all options or convertible securities outstanding or to be issued
on the Closing Date).  The number of Fully Diluted Shares held by each record
holder of Fully Diluted Shares is set forth in Schedule 6.15.

         6.16.   Good Title to Properties.  Borrower and each Subsidiary has
good and marketable title to all its material properties and assets free and
clear of all Liens (except for Permitted Liens).

         6.17.   ERISA.  Neither Borrower nor any ERISA Affiliate maintains or
contributes to or has or could have any liability under, any Plan which is
subject to Title IV of ERISA or Section 412 of the Code.  Neither Borrower nor
any ERISA Affiliate maintains or contributes to or has any liability under, any
Welfare Plan which provides, or has any liability under, benefits to employees
after termination of employment other than as required by Section 601 of ERISA
or state compensation coverage laws, which liability could, singly or in the
aggregate, reasonably be expected to have a Material Adverse Effect.  Neither
Borrower nor any ERISA Affiliate has breached any of the responsibilities,
obligations or duties imposed on it by ERISA, the Code or any other applicable
federal or state law or regulations promulgated thereunder with respect to a
Plan or any Welfare Plan in any manner which could, singly or in the aggregate,
reasonably be expected to result in a Material Adverse Effect.  Neither
Borrower nor any ERISA Affiliate nor any fiduciary of a Plan or any Welfare
Plan has engaged in a nonexempt prohibited transaction described in Sections
406 of ERISA or 4975 of the Code in any manner which could, singly or in the
aggregate, reasonably be expected to result in a Material Adverse Effect.

         6.18.   Insurance.  Borrower has previously delivered to Lender a
summary of the property, casualty and liability insurance program carried by
Borrower and its Subsidiaries (including, without limitation, dental
malpractice, products liability and director's and officer's liability
insurance) and such summary is complete and accurate in all material respects.
Borrower has caused Lender to be named jointly with the purchaser(s) under the
Preferred Stock Purchase Agreement as additional insureds and loss payees under
any or all of Borrower's insurance policies.  Borrower and its Subsidiaries are






 

                                Page 32 of 56
<PAGE>   33
adequately insured for their benefit under such policies.  No notice of
any pending or threatened cancellation or premium increase has been received by
Borrower with respect to any of such insurance policies.  Borrower and its
Subsidiaries are in substantial compliance with all conditions contained in
such insurance policies.

         6.19.   Compliance with Laws.  Neither Borrower nor the Subsidiaries
are in violation of any law, ordinance, rule, regulation, order,
policy, guideline or other requirement of any Governmental Authority, which
violation could, singly or in the aggregate, reasonably be expected to subject
Borrower or the Subsidiaries or any of their officers to criminal liability or
have a Material Adverse Effect on Borrower and no such violation has been
alleged, and Borrower and the Subsidiaries (i) have filed in a timely manner
all reports, documents and other materials required to be filed by it with any
Governmental Authority and the information contained in each of such filings is
true, correct and complete in all respects, except where failure to make such
filings could not reasonably be expected to have a Material Adverse Effect and
(ii) have retained all records and documentary evidence required to be retained
by it pursuant to any law, ordinance, rule, regulation, order, policy,
guideline or other requirement of any Governmental Authority, except where
failure to retain such records could not reasonably be expected to subject
Borrower or any of its officers to criminal liability or have a Material
Adverse Effect.

         6.20.   Absence of Default.  Unless consistent with past practices or
disclosed on Schedule 6.20, Borrower or its Subsidiaries is not in material
default under any material contract or contracts (a) to which it is a party or
by which it is bound, and (b) (i) pursuant to which Borrower or its
Subsidiaries provides goods or material services to a customer which
contributed more than $10,000.00 of gross revenue during the prior fiscal year
of Borrower, (ii) pursuant to which Borrower or its Subsidiaries incurs lease

         6.21.   Securities Laws.  Neither Borrower nor any Affiliate, nor
anyone acting on behalf of any such Person, has directly or indirectly offered
any interest in the Convertible Secured Notes or solicited any offer to acquire
any such interest from, or has taken any action that would subject the issuance
or sale of the Convertible Secured Notes or the issuance of the Shares issuable
upon their conversion to registration under the Securities Act of 1933, as
amended (the "Securities Act") or registration or qualification under the Blue
Sky laws of any state ("Blue Sky Laws").

         6.22.   Employees and Labor.  There is no unfair labor practice
complaint against Borrower or its Subsidiaries pending before the National
Labor Relations Board or any state or local agency nor is there a labor strike
or other labor dispute, pending or, to the best of Borrower's knowledge after
due inquiry, threatened, affecting any of the foregoing which if adversely
resolved could, singly or in the aggregate, reasonably be expected to have a
Material Adverse Effect; to the best knowledge of Borrower after due inquiry,
there is no existing representation question respecting the employees of
Borrower or its Subsidiaries, nor are there organizational attempts affecting
any of the employees of any of the foregoing which could, singly or in the
aggregate, reasonably be expected to have a Material

Adverse Effect; there is no grievance pending or, to the best of
Borrower's knowledge after due inquiry, threatened affecting Borrower or its
Subsidiaries which singularly or in the aggregate with other grievances could,
singly or in the aggregate, reasonably be expected to have a Material Adverse
Effect; and no labor disputes or work stoppages involving Borrower or its
Subsidiaries, to the best of Borrower's knowledge after due inquiry, are
pending or threatened which could, singly or in the aggregate, reasonably be
expected to  have a Material Adverse Effect. To the best of Borrower's
knowledge after due inquiry, no customer or supplier of Borrower or its
Subsidiaries is involved in, or threatened with or affected by, any labor
dispute, arbitration, lawsuit or administrative proceeding which could, singly
or in the aggregate, reasonably be expected to have a Material Adverse Effect.


         6.23.   Finder's Fees.  Except for fees payable under the Letter of
Agreement or hereunder, no agent, broker, investment banker, Person, or firm
acting on behalf of Borrower or any Affiliate of Borrower, or under the
authority of any such Person, is or will be entitled to any broker's or
finder's fee or any other similar commission or similar fee, directly or
indirectly, from any of the parties hereto in connection with any of the
transactions contemplated herein.

         6.24.   Material Adverse Effect.  There is nothing of which Borrower

a Material Adverse Effect which has not been disclosed to Lender in a schedule

                     LENDER REPRESENTATIONS AND WARRANTIES


         7.1.    Acquisition for Investment.  Lender represents and warrants to
Borrower that Lender (i) is acquiring the Convertible Secured Notes for its own
account for investment purposes with no present intention of offering, selling,
transferring or otherwise disposing of the same, any part thereof, or any
interest therein, unless such offer, sale, transfer or other disposition would
not result in a violation of the Securities Act and all applicable Blue Sky
Laws, (ii) has no reason to anticipate any particular occasion or event which
would cause, necessitate or require them to offer, sell, transfer or otherwise
dispose of the Convertible Secured Notes or any interest therein (other than
pursuant to this Agreement) and is able to financially bear the risks of the
investments, and (iii) has no need for liquidity in this investment.

         7.2.    Withholding Certificates.  If any deduction or withholding is
required under federal or state tax laws with respect to any payments to or for
the account of holders of Convertible Secured Notes pursuant to this Agreement,
Borrower shall (i) promptly notify each affected holder in writing of such
requirement, (ii) pay the full amount required to be deducted or withheld to
the applicable taxing authority on a timely basis, (iii) promptly furnish an
official receipt (and such other documentation as may be requested by the
holder) evidencing the payment to such taxing authority.  Each holder agrees
that it will deliver to Borrower, upon reasonably written demand therefor and
at the expense of Borrower, any form or document it can lawfully provide that
may be reasonably requested in writing by Borrower in order to allow Borrower
or any paying agent to make payments to such holder without deduction or
withholding for or on account of such federal or state taxes or with such
deduction or withholding at a reduced rate.

                 the effect that no event of default, or event which with the

                 default under Borrower Transaction Documents.

                       (vii)      Concurrently with the delivery of the

         of compliance therewith is contested in good faith by appropriate
         proceedings or the failure to comply with which could not, singly or
         in the aggregate, reasonably be expected to have a Material Adverse
         Effect.

                 8.1.4.   Keeping of Books.  Keep proper books of record and

         of Borrower or any of its Subsidiaries or upon its property and
         (ii) all lawful claims that, if unpaid, might by law become a Lien
         upon each of Borrower's or its Subsidiaries' property; provided,

                 8.1.8.   [Intentionally Omitted].

         extent that it may lawfully do so, refrain at all times from insisting
         upon, or pleading, or in any manner whatsoever claiming, and resist
         any and all efforts to be compelled to take the benefit or advantage

         contemplated herein, wherever enacted, now or at any time hereafter in
         force; and (to the extent, now or at any time hereafter in force; and

                                Page 38 of 56

         hereby expressly waives all benefit or advantage of any such law, and
         covenants that it will not hinder, delay or impede the execution of
         any right herein granted to Lender, but will suffer and permit the
         execution of every such right as though no such law had been enacted.

                 8.1.10.  Covenants in Agreement.   (i) Comply in all material
         respects and take such actions to have its Subsidiaries comply in all
         material respects with its obligations under this Agreement, the other
         Loan Documents and Borrower Transaction Documents to which they are a
         party (waivers from compliance by any party with the obligations
         specified in this Agreement, the other Loan Documents and Borrower
         Transaction Documents shall not be effective as waivers hereunder
         unless consented to in writing by the Lender), and (ii) refrain from
         entering into any amendment of Borrower Transaction Documents or this
         Agreement or the other Loan Documents without the consent of the
         Lender.

         8.2.    Negative Covenants.  So long as Borrower has any Liabilities

Subsidiaries to, without the written consent of the Lender:

                 8.2.1.   [Intentionally Omitted]

                 8.2.2.   [Intentionally Omitted]

                 8.2.3.   Additional Debt. Incur any Indebtedness or other
         additional debt or obligation of any kind other than that specifically
         permitted pursuant to this Agreement; provided, however, that if
         Borrower makes a borrowing request under Section 2.3.1 and Lender
         fails to make an advance hereunder in response to said request within
         the 30 Business Day period referred to in said section, Borrower may
         borrow the sum requested from another source provided that (a) the
         proceeds of said borrowing are used solely for normal operations
         (excluding the acquisition of dental practices or the prepayment of
         indebtedness), (b) such borrowings do not exceed $750,000 in the
         aggregate or $150,000 in any one instance, (c) such borrowing does not
         violate any other provision of this Agreement, and (d) such borrowing
         is not senior to the Indebtedness due under the Convertible Secured
         Notes and ranks in pari passu with such Indebtedness for security
         purposes.  Lender agrees to execute such documents as are reasonably
         requested by Borrower to acknowledge that such borrowings are pari
         passu with Indebtedness under the Convertible Secured Note for
         security purposes.

                 8.2.4.  Acquisition or Sale of Business; Merger or
         Reorganization.  Purchase or otherwise acquire the stock, shares, or
         other securities, or the assets or business of any Person or other
         entity; or liquidate, dissolve, merge, consolidate, reorganize,
         recapitalize or otherwise alter its legal status or commence any
         proceedings therefor, or sell, lease, transfer or dispose of, in any
         way, any personal or real property assets, except assets sold or
         leased in the ordinary and normal course of business; or assign or
         transfer any substantial part of its intangible business rights
         necessary for the continuation of its business as now conducted or
         planned.

         specifically required pursuant to this Agreement), solicit any offer
         to buy any shares or other securities of Borrower or any Subsidiary,
         or otherwise approach or negotiate in respect thereof with any Person
         in a manner which constitutes a material violation of the Securities
         Act or any other federal, state or other securities law or in such
         circumstances or in such manner as to bring the issue and sale of the
         Shares pursuant to this Agreement or the other Loan Documents into
         material violation of the Securities Act or any other federal, state
         or other securities law.

         such time as Borrower and Subsidiaries collectively generate positive
         net income, determined in accordance with GAAP, for a period of at
         least one (1) year.

         8.3.    Board of Directors.  For so long as the Lender or its
Affiliates or Participants continue to hold any Convertible Secured Notes or
Shares, the Lender shall be entitled to advance written notice of any and all
meetings of any kind or nature of the Board of Directors of Borrower as
follows: (a) sixty (60) days' advance notice in the case of meetings to be held
outside of Cook County, Illinois, (b) fourteen (14) days' advance notice in the
case of meetings to be held in Cook County, Illinois, and (c) such lesser
notice as may be required as a result of an emergency, but in no event less
than five (5) days.  In addition, at the Lender's sole option, it shall be
entitled to attend, or to have its agents or designees attend, any or all such
meetings in order to ensure continuing compliance with the terms and conditions
contained herein and in the other Loan Documents.  Borrower shall be
responsible for paying all fees and expenses (including, without limitation,
travel, lodging, meals and other related expenses) incurred in connection with
attending meetings of the Board of Directors by any of the above-referenced
agents, designees or members of the Board of Directors designated by the Lender
pursuant to this Section 8.3, who shall in addition be paid by Borrower
compensation equal to that paid by Borrower to Directors who are officers of
Borrower but who are not paid an annual salary by Borrower.

         8.4     Preemptive Rights Upon the Issuance of Capital Stock by
Borrower.  At any time that the Convertible Secured Notes are outstanding or
the Lender or its transferees own any Shares or other securities in Borrower,   
if Borrower proposes to issue any Shares or any security or obligation which by
its terms is convertible into Shares or any warrant, option or other
subscription or purchase right with respect to Shares other than pursuant to
the Warrant or pursuant to the Convertible Secured Notes or the Preferred
Stock, Borrower shall first deliver to the Lender a notice with respect to such
proposed issuance which sets forth the price and number of Shares or other such
securities which it proposes to issue.  The Lender shall have the right to
purchase such offered securities at the proposed issuance price (or, if such
securities are to be issued in consideration of services rendered or upon the
conversion or exercise of convertible securities, warrants or options
heretofore issued by Borrower, a sufficient amount of newly issued securities
such that Lender would suffer no dilution, at an amount equal to the fair value
of such services or the actual consideration received by Borrower upon such
conversion or exercise), which right shall be exercisable by the Lender by
written notice to Borrower given on or before ninety (90) days after receipt by
Lender of written notice of such proposed issuance.  Such right shall accrue to
Lender and all holders of the Preferred Stock.  If only Lender exercises such
right, Lender may exercise such right as to any or all of such Shares or other
securities.  If Lender and one or more holders of the Preferred Stock exercise
such right, Lender shall have the right to purchase that portion of the Shares
or other securities purchasable under this section as the unpaid principal
amount of Lender's Convertible Secured Notes bears to the sum of the unpaid
principal amount of Lender's Convertible Secured Notes and the aggregate
purchase price of Preferred Stock held by all holders exercising such right. 
In the event Lender does not exercise its option under this Section 8.4,
Borrower may issue the 



 

                                Page 41 of 56
<PAGE>   42
         offered securities in the amount and at the price set forth in
         such notice to the Lender within one-hundred eighty (180) days of the
         date of such notice.  The closing of any purchase by the Lender under
         this Section 8.4 shall be held at the principal office of the Lender
         at 11:00 a.m. local time on the one-hundred fiftieth (150th) day after
         the date on which the Lender first shall have received notice of the
         proposed issuance, or at such other time and place as the parties to
         the transaction may agree.  Notwithstanding the foregoing, nothing
         contained in this Section 8.4 will waive Lender's right to prevent or
         object to the issuance of Shares or any other securities by Borrower
         or its Subsidiaries.

                                   ARTICLE IX

                               EVENTS OF DEFAULT

         9.1.    Events of Default.  Each of the following events shall
constitute an "Event of Default" hereunder (whatever the reason for such Event
of Default and whether it shall be voluntary or involuntary or be effected by
operation of law or pursuant to any judgment, decree, order, rule or regulation
of any Governmental Authority or otherwise):

                 9.1.1.   Borrower shall (i) fail to pay when due any principal
         amount of, or (ii) fail to pay within five (5) days after due any
         other Liabilities, including interest or any other amount owed under,
         the Convertible Secured Notes or under this Agreement or any other
         Loan Document; or

                 9.1.2.   any representation or warranty by Borrower (or any of
         its officers) under this Agreement or any of the other Loan Documents
         or Borrower Transaction Documents shall prove to have been incorrect
         in any material respect when made; or

                 9.1.3.   Borrower shall fail to perform or observe any of the
         terms, covenants or agreements contained in this Agreement or any of
         the other Loan Documents on its part to be performed or observed if,
         in the case of the covenants in Sections 8.1.1, 8.1.2 and 8.1.4 only,  
         or if, in the case of an inadvertent violation of Section 8.1.3 or
         8.2.7, such failure or violation shall remain unremedied for a period
         of twenty (20) days after written notice thereof shall have been given
         to Borrower by Lender; or

                 9.1.4.   an event of default occurs and is continuing under
         Borrower Transaction Documents if (i) such event of default, after any
         applicable grace period, is an actual payment default on principal or
         interest of any Indebtedness, (ii) as a result of such event of
         default the maturity of such Indebtedness has been accelerated prior
         to its expressed maturity or (iii) such default could reasonably be
         expected to materially impair the ability of Borrower or its
         Subsidiaries to enforce Borrower Transaction Documents in accordance
         with their terms; or

                 9.1.5.   an event of default occurs and is continuing under
         the Preferred Stock Purchase Agreement; or







 

                                Page 42 of 56
<PAGE>   43
                 9.1.6.   Borrower shall generally fail to pay its debts as
         such debts become due, shall admit in writing its inability to pay its
         debts generally, or shall make a general assignment for the benefit of
         its creditors; or any proceeding shall be instituted by or against
         Borrower seeking to adjudicate it bankrupt or insolvent, or seeking
         liquidation, winding up, reorganization, arrangement, adjustment,
         protection, relief or composition of it or its debts under any law
         relating to bankruptcy, insolvency, reorganization or relief of
         debtors, or seeking the entry of an order for relief or the
         appointment of a receiver, trustee or other similar official for it or
         for any substantial part of its property and, in the case of any such
         proceeding instituted against it (but not instituted by it), either
         such proceeding shall remain undismissed or unstayed for a period of
         30 days or any of the actions sought in such proceeding (including,
         without limitation, the entry of an order for relief against it or the
         appointment of a receiver, trustee, custodian or other similar
         official for it or for any substantial part of its property) shall
         occur; or Borrower shall take any action to authorize any of the
         actions set forth above in this Section 9.1.6; or

                 9.1.7.   any Person entitled to take the actions described in
         this Section 9.1.7, after the occurrence of any default or event of
         default under any agreement, mortgage, indenture or instrument
         evidencing any Indebtedness of Borrower which is outstanding in a
         principal amount of at least $10,000.00 in the aggregate, shall notify
         Borrower of the intended sale or disposition of any assets of Borrower
         that have been pledged to or for the benefit of such Person to secure
         such Indebtedness or shall commence proceedings or take any action
         (including by way of set-off) to retain in satisfaction of any such
         Indebtedness, or to collect on, seize, dispose of, or apply, any
         assets of Borrower (including funds on deposit or held pursuant to
         lock box and other similar arrangements), pursuant to the terms of any
         agreement or instrument evidencing any such Indebtedness or in
         accordance with applicable law; or

                 9.1.8.   there remains unpaid and unstayed pending appeals for
         more than thirty (30) consecutive days, one or more judgments or
         decrees against Borrower, any Subsidiary or any guarantor of any of
         the Liabilities involving an aggregate liability of $25,000.00 or
         more (other than a money judgment covered by insurance, but only if
         the insurer has admitted, in writing, liability with respect to such
         judgment); or

                 9.1.9.   if any of the present executive officers of Borrower
         are no longer personally and actively involved in the management and
         supervision of Borrower or any of its Subsidiaries, at least
         substantially to the same extent as of the date hereof, except that,
         if any of them is no longer so involved due to his death or
         disability, such event shall not be an Event of Default if he is
         replaced within 45 days by another person acceptable to the Lender in
         its Sole and Exclusive Discretion (which must be evidenced in writing
         by Lender).

         Notwithstanding the foregoing, the mere failure to pay interest under
the Convertible Secured Notes which is due in June 1996 or September 1996 or
the mere failure to pay dividends on the Preferred Shares which is due on June
30, 1996 or September 30, 1996 shall not be an Event of Default for any purpose
hereunder, except that (1) such failure to pay in September 1996 shall trigger
interest 





 

                                Page 43 of 56
<PAGE>   44
at the Default Rate under the Convertible Debt Agreement and dividends
at the Default Rate under the Certificate of Designation, and (2) interest
which is unpaid in June 1996 shall be added to principal.

         9.2.    Remedies.  If an Event of Default (other than an Event of
Default specified in Section 9.1.6) occurs and is continuing, Lender may, by
notice to Borrower (the "Default Notice"), declare the then-outstanding
principal amount and accrued interest on the Convertible Secured Notes to be
immediately due and payable.  In the event of a declaration of acceleration
because an Event of Default specified under Section 9.1.4(ii) (whether or not
it also results in an Event of Default under Section 9.1.4(i)) has occurred and
is continuing, such declaration of acceleration shall be automatically annulled
if the underlying event(s) causing such Event of Default is cured or
permanently waived or the holders of the Indebtedness which is the subject of
such underlying event(s) have rescinded their declaration of acceleration in
respect of such Indebtedness within 90 days thereof and Lender has received
written notice of such cure, permanent waiver or rescission and no other Event
of Default has occurred during such period which has not been cured or waived.
If an Event of Default specified in Section 9.1.6 occurs, the amounts referred
to in the first sentence of this Section 9.2 shall ipso facto become and be
immediately due and payable without any declaration or other action on the part
of Lender.  The Lender by notice to Borrower may rescind any acceleration and
its consequences if the rescission would not conflict with any judgment or
decree and if all existing Events of Default hereunder have been cured or
waived except nonpayment of principal or interest that has become due solely
because of the acceleration.

                              LIMITED CALL RIGHTS



         10.1.   Limited Call Right.  During the period commencing on the date
that Lender has provided Convertible Loans and the purchasers under the
Preferred Stock Purchase Agreement have purchased Preferred Stock in the
initial aggregate principal amount of One dollar ($1.00) or more and ending on
the earlier to occur of one year after the Closing Date or when no Indebtedness
remains outstanding under the Convertible Secured Notes and no Preferred Stock
remains outstanding, Borrower may give Lender (or its transferees) notice of
its intention to purchase and redeem ("Call") all (but not less than all) of
the Indebtedness then outstanding under the Convertible Secured Notes
(collectively, the "Called Debt") if the conditions described in Section 10.2
hereof have been complied with at and prior to the time of Borrower's exercise
of the Call, and thereupon Lender (or its transferees) shall sell to the
Company the Called Debt as provided in this Article 10.

         10.2.   Conditions to Call.  The Call may be exercised and consummated
only if:  (i) no Event of Default has occurred and is continuing nor any Event
of Default would occur, after giving effect to the exercise of the Call, with
the passage of time, the giving of notice, or both; (ii) the exercise of the
Call (and the resulting partial prepayment of the Convertible Secured Note) is
not prohibited by


 

                                Page 44 of 56
<PAGE>   45
applicable corporate or other law or pursuant to the terms or
covenants of any loan agreement, note, security agreement or other instrument
binding upon the Company, (iii) concurrently therewith, Borrower calls for
redemption that portion of the Preferred Stock (the "Called Preferred Stock")
which bears the same percentage of the total outstanding Preferred Stock as the
Called Debt bears to the total outstanding indebtedness under the Convertible
Secured Notes, (iv) concurrently therewith, Borrower either (A) deposits in
escrow with Agent (or, if no Agent has been appointed, with Lender) an amount
in cash equal to five (5) percent of the Call Price (the "Deposit") or (B)
delivers to Lender a written, unconditional commitment from a third party to
provide funds sufficient to consummate the Call and evidence satisfactory to
Lender that such third party has sufficient liquid assets available for that
purpose, and (v) Lender does not exercise its right to convert the Called Debt
within 90 Business Days after the Call is made.  At the closing of the Call,
the Deposit shall, if made under Clause (A) above, be paid by Agent to Lender
and applied against the Call Price.  If the Call fails to close in accordance
with or within the time period provided in Section 10.5 (other than due to
Lender's default or to the conversion of the Called Debt), the Deposit shall,
if made under clause (A) above, be paid by Agent to Lender as liquidated
damages, such failure to close shall constitute an Event of Default and
Borrower shall not be entitled to close the Call or to make any subsequent
Call.

         10.3.   [Intentionally Omitted]

         10.4.   Call Price.  The purchase price ("Call Price") of the Called
Debt shall be the amount of such Indebtedness plus (a) if the Call is made
within 180 days after the Closing Date, a premium of $375,000, (b) if the Call
is made more than 180 days but within 270 days after the Closing Date,


a premium of $500,000, and (c) if the Call is made more than 270 days but
within 360 days after the Closing Date, a premium of $750,000.  The portion of
the Call Price determined under clause (a), (b) or (c) of the preceding
sentence (the "Premium") shall be allocated among the holders of the Preferred
Stock and Lender in proportion to the ratio that the Liquidation Value (as
defined in the Certificate of Designation) of the Called Stock bears to the
amount of the Indebtedness represented by the Called Debt.

         10.5.   Exercise of Call.  Borrower may exercise the Call (subject to
the terms and conditions hereinabove set forth) by delivery to Lender during
the period of the effectiveness of the Call of written notice of exercise of
the Call, which notice shall specify the amount of the Convertible Secured
Notes which Borrower elects to Call and shall contain a statement, certified by
the Chief Executive Officer of Borrower, that each of the conditions to the
exercise and to the closing of the Call hereinabove set forth has been
fulfilled.  The closing of the Call shall take place at the principal offices
of the Lender, or where Lender designates, on or before 110 Business Days after
the exercise of the Call, and shall take place concurrently with the redemption
of the Called Preferred Stock; provided, however, that if Lender agrees by
written notice to Borrower to accept the Call as to any portion of the Called
Debt and to waive its right to convert such portion of the Called Debt prior to
the expiration of such conversion right, the closing of the Call as to such
portion shall take place within 20 Business Days after such notice is given.
At the closing, Agent (a) shall receive from Borrower by wire transfer
immediately available funds in an amount equal to the Call Price, plus all
accrued but unpaid interest in respect of the Called


 

                                          Page 45 of 56
<PAGE>   46
Debt, and (b) shall receive from Lender the Convertible Secured Note
being Called.  Upon receipt of all of such items, Agent shall deliver to
Borrower the Called Convertible Secured Note for cancellation and shall deliver
to Lender the above funds.

         10.6.   No Other Call or Prepayment Rights.  Except as permitted in
this Article X, the Borrower shall not be entitled to call or prepay the
outstanding Convertible Secured Notes.

                                   ARTICLE XI

                         ASSIGNMENTS AND PARTICIPATIONS


         11.1    Assignments.  Assignments or participations by Lender of its
rights and obligations arising under and with respect to this Agreement and the
other Loan Documents shall be subject to the following terms and conditions:

                    11.1.1.  The Lender may assign and delegate (the 
         "Assignment") to one or more assignees (the "Assignees") all or a 
         portion of its rights and obligations under this Agreement or the Loan
         Documents (including, without limitation, all or any portion of the
         Convertible Loan and its interest in the Convertible Secured Notes)
         subject only to the conditions set forth in Section 11.1.2.  After any
         Assignment  permitted under this Section 11.1.1, Lender shall have no
         further  obligations with respect to the portion of its rights and
         obligations so assigned arising after the date of such Assignment.

                    11.1.2.  Any Assignment shall identify the party to whom the
         Convertible Loan is being assigned and the amount of the Convertible
         Loan being assigned.  Unless such Assignment is to a Controlled
         Affiliate of Lender, such Assignment shall also require the prior
         written consent of one of the holders of the Preferred Stock.

         11.2.   Participations.  Participations by any Lender of its rights
and obligations arising under and with respect to this Agreement shall be
subject to the following terms and conditions:

                    11.2.1.  The Lender may sell participations (the 
         "Participations") to one or more participants (the "Participants") in
         or to all or any portion of its rights and obligations under this
         Agreement (including, without limitation, all or any portion of the
         Convertible Loan and its interest in the Convertible Secured Notes or
         the other Loan Documents) subject to such terms and conditions as
         Lender may agree to with such Participants.  After any such sale
         permitted under this Section 11.2, Lender shall have no further
         obligations with respect to the portion of its rights and obligations
         so sold arising after the date of such sale.

                    11.2.2.  Borrower agrees that if amounts outstanding under
         this Agreement and the Convertible Secured Notes are due and unpaid,
         or shall have been declared due and payable,





 

                                          Page 46 of 56
<PAGE>   47
         then, to the extent permitted by applicable law, the
         Participant shall be deemed to have the right to set-off in respect of
         its participating interest in amounts owing under this Agreement and
         the Convertible Secured Notes to the same extent as if the amount of
         its participating interest were owing directly to it under this
         Agreement or such Convertible Secured Notes; provided, that any
         Participant exercising such right shall be obligated to share with the
         Lender the amount of any such set-off.

                    11.2.3.  The Lender may, in connection with any Assignment
         or Participation or proposed Assignment or Participation pursuant to
         Sections 11.1 and 11.2, disclose to the Assignee or Participant or
         proposed Assignee or Participant any information relating to Borrower
         furnished to such Lender by or on behalf of Borrower.

                    11.2.4.  Borrower hereby irrevocably authorizes Amsterdam
         Equities Limited to act, and Amsterdam Equities Limited hereby agrees
         to act, as agent for any Assignee or Participant and to exercise all
         rights and discharge all obligations of Lender hereunder on behalf of
         such Participants or Assignees and Borrower agrees to recognize, be
         bound by and consent to such agency relationship as Lender may enter
         into in connection with a Participation or Assignment.  Each Assignee
         and Participant agrees to be bound by any actions taken by said agent
         on its behalf and to take no actions independently of said agent.


                    11.2.5.  Unless such Participants are Controlled Affiliates
         of Lender, such Participation shall require the prior written consent
         of one of the holders of the Preferred Stock.


                                  ARTICLE XII

                                   THE AGENT


         12.1.   Appointment.  Lender may appoint an Agent to act as escrow
agent hereunder by written notice to Borrower.  In the event of such
appointment, the Agent shall be authorized to take such action on behalf of
Lender and Borrower under the provisions of this Agreement, the other Loan
Documents and any other instruments and agreements referred to herein or
therein and to exercise such powers and to perform such duties hereunder and
thereunder as are specifically delegated to or required of the Agent by the
terms hereof and thereof and such other powers as are reasonably incidental
thereto.  The Agent may perform any of its duties hereunder by or through its
officers, directors, agents or employees.

         12.2.   Nature of Duties.  The Agent shall not have any duties or
responsibilities except those expressly set forth in this Agreement.  Neither
the Agent nor any of its officers, directors, agents or employees shall be
liable for any action taken or omitted by it or them hereunder or under any
other Loan Document or in connection herewith or therewith, unless caused by
its or their gross negligence or willful misconduct.  However, the Agent will
use reasonable care in the custody of funds deposited


 

                                Page 47 of 56
<PAGE>   48
with it hereunder.  The duties of the Agent shall be mechanical and
administrative in nature; the Agent shall not have by reason of this Agreement
or any other Loan Document a fiduciary relationship in respect of the Lender or
Borrower and nothing in this Agreement or any other Loan Document, expressed or
implied, is intended to or shall be so construed as to impose upon the Agent
any obligations in respect of this Agreement or any other Loan Document except
as expressly set forth herein.

                                      
         12.3.   Lack of Reliance on the Agent.  In acting as Agent hereunder,
the Agent shall not be responsible to the Lender or Borrower for any recitals,
statements, information, representations or warranties herein or in any
document, certificate or other writing delivered in connection herewith or for
the execution, effectiveness, genuineness, validity, enforceability,
perfection, collectibility, priority or sufficiency of this Agreement or any
other Loan Document or the financial condition of Borrower or any of its
Subsidiaries or be required to make any inquiry concerning either the
performance or observance of any of the terms, provisions or conditions of this
Agreement or any other Loan Document, or the financial condition of Borrower or
any of its Subsidiaries or the existence or possible existence of any Default
or Event of Default.


         12.4.    Certain Rights of the Agent.  The Agent shall act only in
accordance with (a) the terms of this Agreement, (b) written instructions
executed by both Lender and Borrower, or (c) an order of a court which is no
longer subject to appeal and which Agent is advised by counsel is binding upon
it.  If the Agent shall request instructions from the Lender and Borrower with
respect to any act or action (including failure to act) in connection with this
Agreement or any other Loan Document which is not expressly provided for
herein, the Agent shall be entitled to refrain from such act or taking such
action unless and until the Agent shall have received instructions from the
Lender and Borrower, and the Agent shall not incur any liability to any Person
by reason of so refraining.  Without limiting the foregoing, neither the Lender
nor Borrower shall have any right of action whatsoever against the Agent as a
result of the Agent acting or refraining from acting hereunder or under any

         12.7.   Holders.  The Agent may deem and treat the payee of any
Convertible Secured Note as the owner thereof for all purposes hereof unless
and until a written notice of the assignment, transfer or endorsement thereof,
as the case may be, shall have been filed with the Agent.  Any request,
authority or consent of any Person or entity who, at the time of making such
request or giving such authority or consent is the holder of any Convertible
Secured Note shall be conclusive and binding on any subsequent holder,
transferee, assignee or indorsee, as the case may be, of such Convertible
Secured Note or of any Convertible Secured Note or Convertible Secured Notes

         12.8.   Resignation.

                 (a)      The Agent may resign from the performance of all its
         functions and duties hereunder and/or under the other Loan Documents
         at any time by giving 15 Business Days' prior written notice to
         Borrower and the Lender.  Each such resignation shall take effect upon
         the expiration of such 15-day period, provided that the resignation of
         the last remaining Agent shall take effect upon the appointment of a
         successor Agent, pursuant to clauses (b) and (c) below or as otherwise
         provided below.

                 (b)      Upon any such notice of resignation of the last
         remaining Agent, the Lender shall appoint a successor Agent.

                 (c)      Following any notice of resignation by any Agent, if
         a successor Agent shall not have been so appointed within said 15
         Business Days, such Agent shall then appoint a successor Agent who
         shall serve as Agent hereunder or thereunder until such time, if any,
         as the Lender appoints a successor Agent as provided above.

                 (d)      If no successor Agent has been appointed pursuant to
         clause (b) or (c) above by the 20th Business Day after the date such
         notice of resignation was given by the Agent, Agent's resignation
         shall become effective and the Lender shall thereafter perform all the
         duties of the Agent hereunder and/or under any other Loan Document
         until such time, if any, as the Lender appoints a successor Agent as
         provided above.

         13.3.    No Waiver; Remedies.  No failure on the part of Lender to     
exercise, and no delay in exercising, any right hereunder or under the other

right.  The remedies herein provided are cumulative and not exclusive of any

         13.4.   Costs and Expenses; Indemnity.

                 13.4.1.  Borrower shall pay on demand (i) all reasonable costs

         delivery, administration, modification and amendment of this Agreement
         and the Loan Documents, including, without limitation, the fees and
         out-of-pocket expenses of counsel for Lender with respect thereto and
         other legal counsel advising any successors or assigns of Lender as to
         their respective rights and responsibilities under this Agreement, and
         due diligence, transportation, lodging, meals, computer, duplication,
         appraisal, audit, insurance, consultant, search and filing fees, costs
         and expenses of Lender, and (ii) all reasonable costs and expenses, if

         enforcement (whether through negotiations, legal proceedings or
         otherwise) of their respective rights under this Agreement and the
         Loan Documents.

                 13.4.2.  Borrower shall indemnify and hold harmless Lender and
         any Assignees and Participants and their respective Affiliates (each
         such Person being an "Indemnified Party") from and against any and all
         losses, claims, damages, liabilities and expenses (including, without
         limitation, fees and disbursements of counsel and out of pocket

         any investigation, inquiry, litigation or proceeding (i) relating to

<PAGE>   51
                party (other than an Indemnified Party) relating to any act,
         omission or obligation of Borrower or its stockholders, directors,
         officers, agents, employees, creditors or Affiliates or (iii) any
         breach of any written obligation of Borrower or its Affiliates to
         Lender, whether or not such Indemnified Party is a party thereto and
         whether or not the transactions contemplated herein are consummated. 
         Borrower will not be liable to any Indemnified Party under the
         foregoing indemnification provision to the extent that any loss,
         claim, damage, liability or expense incurred by or asserted or awarded
         against such Indemnified Party is found to have resulted from the
         willful misconduct or gross negligence of such Indemnified Party as
         determined by a final judgment of a court of competent jurisdiction. 
         The agreements in this Section 13.4.2 shall survive repayment of the

(general or special, time or demand, provisional or final) at any time held and
other Indebtedness at any time owing by Lender and any Assignees and
Participants to or for the credit or the account of Borrower against any and
all of the Liabilities irrespective of whether or not the Lender and any such
Assignees and Participants shall have made any demand under this Agreement or
the Convertible Secured Notes and although such obligations may be unmatured. 
Lender and any Assignees and Participants agree promptly to notify Borrower
after any such set-off and application made by Lender or any Assignees or
Participants, provided that the failure to give such notice shall not affect
the validity of such set-off and application.  The rights of Lender or any
Assignee or Participants under this Section 13.5 are in addition to other
rights and remedies (including, without limitation, other rights of set-off)
which such Purchaser or such Assignee or Participants may have hereunder, under
the Loan Documents, or pursuant to applicable law.

         13.6.   Construction.  The use of the singular or plural or masculine
or neuter gender shall not be given an exclusionary meaning and, where
applicable, shall be intended to include the appropriate number or gender, as
the case may be.  The failure of this Agreement to use the term "Sole and
Exclusive Discretion" in connection with any act or failure to act of Lender
hereunder shall not be deemed to imply any obligation on the part of Lender to
act or fail to act except in its Sole and Exclusive Discretion.

         13.7.   Execution in Counterparts.  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.

written consent

governed by, and construed in accordance with, the laws of the State of
Illinois, without regard to its principles of conflicts of law.

         13.9.   Severability.  The invalidity of any provision of this
Agreement or portion of a provision shall not affect the validity of any other
portion of this Agreement or the remaining portion of the applicable provision.

         13.10.  Submission to Jurisdiction.  BORROWER HEREBY IRREVOCABLY
SUBMITS TO THE JURISDICTION AND EXCLUSIVE VENUE OF ANY STATE OR FEDERAL

         existing Accounts as Secured Party shall request.

                 10.8     Notice Regarding Disputed Accounts.  Debtor shall
         give Secured Party prompt notice of (i) any Accounts individually in
         excess of two thousand five hundred dollars ($2,500) between any

         items of Collateral.  Debtor shall upon Secured Party's request,
         deliver to Secured Party evidence of its ownership of or interest in
         the Collateral.

         11.     PROTECTION OF COLLATERAL.  If Debtor fails to, in accordance
with the respective terms and provisions of this Security Agreement and the
Debt Agreement, (I) maintain in force and pay the premium with respect to any
insurance policy or bond which Debtor is required to maintain, (II) keep the

tear excepted, (III) keep the Collateral free from all Liens except for Liens
in favor of Secured Party and Permitted Liens, (IV) pay when due all taxes,
levies and assessments on or in respect of the Collateral, except as otherwise
permitted pursuant to the terms of SECTION 6 above, (V) make all payments and
perform all acts on the part of Debtor to be paid or performed with respect to
any of the Collateral, including, without limitation, all expenses of
protecting, storing, warehousing, insuring, handling and maintaining the
Collateral and (VI) keep fully and perform promptly any other of the
obligations of Debtor under this Security Agreement, the Debt Agreement or any
of the Loan Documents, then Secured Party, at its option, may (but shall not be
required to), procure and pay for such insurance policy or bond, place such
Collateral in good repair and operating condition, pay, contest or settle such
Liens or taxes or any judgments based thereon or otherwise make good any other
aforesaid failure of Debtor and Secured Party may direct any insurer of the
Collateral to make any payments to Secured Party that would otherwise be paid
to Debtor.  Debtor shall reimburse Secured Party immediately upon demand for
all sums paid or advanced on behalf of Debtor for any such purpose, together
with costs and expenses (including reasonable attorneys' fees) paid or incurred
by Secured Party in connection therewith and interest on all sums advanced from
the date of advancement until repaid at the Default Rate.  All such






                                 Page 7 of 16
<PAGE>   68
sums advanced by Secured Party, with interest thereon, immediately upon 
advancement thereof, shall constitute Liabilities secured hereby.

         12.     FINANCING STATEMENT, FURTHER ASSURANCES.  Debtor, concurrently
with the execution of this Security Agreement, and from time to time hereafter
as requested by Secured Party, shall execute and deliver to Secured Party such
financing statements, continuation statements, termination statements and other
documents, in form satisfactory to Secured Party, as Secured Party may require
to perfect and continue in effect the Lien granted pursuant to this Security
Agreement, to carry out the purposes of this Security Agreement, and to protect
the rights of Secured Party hereunder.  Debtor, upon demand, shall pay the cost
of filing all such financing statements, continuation statements, termination
statements and other documents.

         13.     REMEDIES UPON DEFAULT.  If an Event of Default shall have
                 occurred and be continuing:

                 13.1  Secured Party may exercise in respect of the Collateral,
         in addition to all other rights and remedies provided for herein, all
         of the rights and remedies of a secured party on default under the
         Code (and whether or not the Code applies to the affected Collateral)
         and all other rights and remedies accorded to Secured Party at law or
         in equity, including, without limitation, the right to apply for and
         have a receiver appointed by a court of competent jurisdiction to
         manage, protect and preserve all or any part of the Collateral,
         continue the operation of Debtor's business and to collect all
         revenues therefrom and profits thereof. Debtor acknowledges that any
         notice of sale or other disposition of Collateral given not less than
         five (5) days prior to such proposed action shall constitute
         reasonable and fair notice of such action.  Secured Party may postpone
         or adjourn any such sale from time to time by announcement at the time
         and place of sale stated in the notice of sale or by announcement of
         any adjourned sale, without being required to give a further notice of
         sale.  Any such sale may be for cash or, unless prohibited by
         applicable law, upon such credit or installment terms as Secured Party
         shall determine.  Debtor shall be credited with the net proceeds of
         such sale only when such proceeds actually are received by Secured
         Party.  Despite the consummation of any such sale, Debtor shall remain
         liable for any deficiency on Borrower's Obligations which remains
         outstanding following any such sale.

                 13.2  Upon the request of Secured Party, Debtor shall assemble
         and make the Collateral available to Secured Party at a place
         designated by Secured Party.

                 13.3  Upon the request of Secured Party, Debtor, at its own
         expense, shall execute all applications and other documents and take
         all other action requested by Secured Party to (I) enable Secured
         Party or its designee to obtain from any Governmental Authority or
         other entities any required special temporary authority necessary to
         operate Debtor's business and/or (II) to the extent permitted by law,
         obtain an approvals of any Governmental Authority or other entities to
         the transfer of or granting to Secured Party the temporary right to
         utilize all licenses, franchises, trademarks, trade names and permits
         issued to Debtor in connection with the operation of Debtor's
         business.

                 13.4  All proceeds collected by Debtor from any
                 obligor or account debtor with respect to any account,
                 contract right, chattel paper or general intangible shall be
                 held by Debtor in trust for Secured Party and immediately
                 delivered to Secured Party in the exact form in which such
                 proceeds were received.

                 13.5  Secured Party at its election, and without notice to
                 Debtor, may:

                 (A)      terminate the right of Debtor to collect the proceeds
                          described in SUBSECTION 13.4,

                 (B)      notify the obligors under any instruments and the
                          account debtors of any account, contract right,
                          chattel paper or general intangible to make all
                          payments directly to Secured Party,

                 (C)      demand, sue for, collect or receive, in the name of
                          Debtor or Secured Party, any money or property
                          payable or receivable on any item of Collateral,

                 (D)      settle, release, compromise, adjust, sue upon or
                          otherwise enforce any item of Collateral as the
                          Collateral may determine, and

                 (E)      for the purpose of enforcing Secured Party's rights
                          under this Security Agreement, Secured Party may
                          receive and open mail addressed to Debtor, and
                          endorse notes, checks, drafts, money orders,
                          documents of title or other forms of payment on
                          behalf and in the name of Debtor.

All cash proceeds received by Secured Party in respect of any sale of,
collection from, or other realization upon all or any part of the Collateral
may, in the discretion of Secured Party, be held by Secured Party as collateral
for, and/or then or at any time thereafter be applied in whole or in part by
Secured Party against, all or any part of the Liabilities in such order as
Secured Party shall elect.  Any surplus of such cash or cash proceeds held by
Secured Party and remaining after payment and satisfaction in full of all of
the Liabilities shall be paid over to the Debtor or to whomsoever may be
lawfully entitled to receive such surplus.

         14.     POWER OF ATTORNEY.  To effectuate the rights and remedies of
Secured Party under this Security Agreement, Debtor hereby irrevocably appoints
Secured Party as its attorney-in-fact, with full power of substitution and with
full authority in the place and stead of Debtor and in the name of the Debtor
or otherwise:

                 (I)      to execute and file from time to time financing
         statements, continuation statements, termination statements and
         amendments thereto, covering the Collateral, in form satisfactory to
         Secured Party; and

                 (II)     upon the occurrence of an Event of Default to take
         all action and execute all documents referred to in SECTION 12 above,
         to the extent permitted by law.





                                 Page 9 of 16
<PAGE>   70
The power of attorney granted pursuant to this SECTION 14 is coupled with an 
interest and shall be irrevocable until all of Borrower's Obligations have 
been paid and performed in full.

         15.     WAIVERS.  Debtor hereby waives notice of the acceptance of
this Security Agreement and, all other notices, demands or protests to which
Debtor otherwise might be entitled by law (and which lawfully may be waived),
with respect to this Security Agreement, any of the Liabilities or the
Collateral.  Debtor agrees that Party (I) shall have no duty as to the
collection or protection of the Collateral or any income thereon, (II) may
exercise the rights and remedies of Secured Party with respect to the
Collateral without resort or regard to other security or sources for payment
and (III) shall not be deemed to have waived any of the rights or remedies
granted to Secured Party hereunder unless such waiver shall be in writing and
shall be signed by Secured Party.  No delay or omission on the part of Secured
Party in exercising any rights or remedies contained herein, in the Debt
Agreement or in any of the Loan Documents shall operate as a waiver of such
right or remedy or of any other right or remedy, and no single or partial
exercise of any right or remedy shall preclude any other or further exercise
thereof, or the exercise of any other right or remedy.  A waiver of any right
or remedy on any one occasion shall not be construed as a bar or waiver of any
right or remedy on future occasions, and no delay, omission, waiver or single
or partial exercise shall be deemed to establish a custom or course of dealing
or performance between the parties hereto.

         16.     RIGHTS CUMULATIVE.  All rights and remedies of Secured Party
pursuant to this Security Agreement, the Debt Agreement, any of the Loan
Documents or otherwise, shall be cumulative and non-exclusive, and may be
exercised singularly or concurrently.

         17.     SEVERABILITY.  If any provision of this Security Agreement is
deemed to be invalid by reason of the operation of any law, or by reason of the
interpretation placed thereon by any court or any Governmental Authority, this
Security Agreement shall be construed as not containing such provision and the
invalidity of such provision shall not affect the validity of any other
provisions hereof, and any and all other provisions hereof which otherwise are
lawful and valid shall remain in full force and effect.

         18.     NOTICES, ETC.  All notices, requests and other communications
provided for hereunder shall be in writing and sent by first class or
equivalent mail of the country of origin, registered or certified, postage
prepaid and return receipt requested or delivered personally or by courier

Party.  All such notices and other communications shall be effective on the
date of delivery to the party receiving such notice, as evidenced by the date
set forth on the receipt signed by the party receiving such notice.

         19.     CONTINUING SECURITY INTEREST; SUCCESSORS AND ASSIGNS.  This
Security Agreement shall create a continuing security interest in the
Collateral and shall (I) remain in full force and effect until payment and
satisfaction in full of all of the Liabilities , (II) be binding upon the

limiting the generality of the foregoing CLAUSE (III), Secured Party may assign
or otherwise transfer any promissory note or other instrument evidencing all or
any part of the Liabilities to any other person or entity, and such other
person or entity shall thereupon become vested with all of the benefits in
respect thereof granted to or for the benefit of Secured Party hereunder or
otherwise.  Debtor's successors  and assigns shall include, without limitation,
a receiver, trustee or debtor-in-possession of or for Debtor.  Upon the payment
and satisfaction in full of the Liabilities and termination of the Debt
Agreement pursuant to the respective terms and provisions thereof, the security
interest granted hereby shall terminate and all rights to the Collateral shall
revert to the Debtor.  Upon any such termination, Secured Party will, upon the
request and at the sole expense of the Debtor execute and deliver to the Debtor
such documents as the Debtor shall reasonably request to evidence such
termination.

         20.     GOVERNING LAW.  This Security Agreement shall be governed by,

HEREAFTER BE SELECTED BY DEBTOR WHICH IRREVOCABLY AGREE IN WRITING TO SO SERVE

RELATIONSHIP EXISTING IN CONNECTION WITH THIS SECURITY AGREEMENT, AND DEBTOR
AGREES THAT ANY SUCH ACTION OR PROCEEDING SHALL BE TRIED BEFORE A COURT AND NOT
BEFORE A JURY.

         23.     CAPTIONS.  The headings in this Security Agreement are for

                                                               APRIL __, 1996

         FOR VALUE RECEIVED, the undersigned, Princeton Dental Management
Corporation, a Delaware corporation "BORROWER", promises to pay to the order of
Amsterdam Equities Limited ("LENDER"), at such place or places as the Lender
may from time to time designate to such Borrower in writing, the principal
amount of THIRTEEN MILLION FIFTY 00/100 DOLLARS ($13,050,000), or so much
thereof as may have been disbursed by Lender, PLUS interest thereon as provided
below.  The principal amount of this Convertible Secured Note (this "NOTE")
shall be payable in the manner provided in the Convertible Debt Agreement of
even date herewith among the Borrower and Lender (such agreement, as amended,
extended, restated, supplemented or otherwise modified from time to time, the
"CONVERTIBLE DEBT AGREEMENT").  All terms used herein which are not otherwise
defined herein shall have the meanings ascribed to them in the Convertible Debt
Agreement.

         The liabilities and obligations of Borrowers to Lender under this Note
(the "Liabilities") which are outstanding and unpaid from time to time (other
than accrued but unpaid interest) shall bear interest at the rate and in
accordance with the Convertible Debt Agreement.  If any of the Liabilities are
not paid when due and payable or declared due and payable, interest shall
accrue thereon at the applicable Default Rate set forth in the Convertible Debt
Agreement.  Such amounts shall be part of the Liabilities, immediately due and
payable by Borrowers to Lender without notice by the Lender to or demand by the
Lender of the Borrower.

         Upon the occurrence of an Event of Default, without notice by the
Lender to or demand by Lender of the Borrower, all of the Liabilities shall be
due and payable, forthwith.  The acceptance by the Lender of any partial
payment made hereunder after the time any of the Liabilities becomes due and
payable will not establish a custom, or waive any rights of the Lender to
enforce prompt payment hereof.  Borrower and every endorser hereof waive
presentment, demand and protest and notice of presentment, protest, default,
non-payment, maturity, release, compromise, settlement, extension or renewal of
this Note.

         This Note and the Liabilities evidenced hereby are secured by the
Liens heretofore, now or hereafter granted to Lender, for its benefit, as
described in the Convertible Debt Agreement and the Loan Documents.

         If any provision of this Note or the application thereof to any party
or circumstance is held invalid or unenforceable, the remainder of this Note
and the application of such provision to other parties or circumstances will
not be affected thereby and the provisions of this Note shall be severable in
any such instance.

Illinois as to interpretation, enforcement, validity, construction, effect and
in all other respects.

         THIS WARRANT, AND THE SECURITIES ISSUABLE UPON THE EXERCISE OF THIS
         WARRANT, HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS
         AMENDED (THE "ACT"), OR THE SECURITIES LAWS OF ANY OTHER JURISDICTION
         AND ANY TRANSFER THEREOF IS SUBJECT TO COMPLIANCE WITH SUCH LAWS AND
         THE TERMS OF THIS WARRANT.


                           WARRANT TO PURCHASE UP TO
                3,588,750 UNREGISTERED SHARES OF COMMON STOCK OF
                    PRINCETON DENTAL MANAGEMENT CORPORATION

NO. __


         FOR VALUE RECEIVED, Princeton Dental Management Corporation, a
Delaware corporation located at 2358 Hassell Road, Hoffman Estates, Illinois
60195 (the "Company"), promises to issue in the name of, and sell and deliver
to the party identified on Exhibit A attached hereto and incorporated herein,
together with its successors, transferees and assigns (the "Holder") (when the
context requires, the Company and the Holder shall be collectively referred to
as the "Parties"), a certificate or certificates for an aggregate of Three
Million Five Hundred Eighty Eight Thousand Seven Hundred Fifty (3,588,750)
unregistered shares of Common Stock, One Ten Thousandth of One United States
Dollar (U.S.$.0001) par value per share (the "Shares"), of the Company, upon
payment therefor of Ten United States Cents ($0.10) per Share in lawful funds
of the United States of America (the "Exercise Price") pursuant to the terms
hereof.

         1.      Definitions.  Unless defined otherwise, any term used herein
which has the first letters thereof capitalized, exclusive of prepositions and
articles, shall be defined as such capitalized term is defined in that certain
Convertible Debt Agreement, dated as of April 22, 1996, by and between the
Parties (which such Convertible Debt Agreement is hereby incorporated herein
and made a part hereof by this reference thereto).

         2.      Exercise of Warrant.  The Holder of this Warrant shall be
entitled to purchase such numbers of Shares at any time over approximately a
ten (10) year period commencing on the effective date of this Warrant and
ending at 6:01 P.M. Eastern Standard Time on the date ten (10) years after such
date.

         In case the Holder of this Warrant shall desire from time to time to
exercise this Warrant in whole or in part, the Holder shall surrender a copy of
this Warrant, with a copy of the form of exercise notice marked Exhibit B,
which is attached hereto, incorporated herein and made a part hereof by this
reference thereto, duly executed by the Holder (said exercise notice shall bear
an original signature of the Holder), to the Company, accompanied by payment of
the Exercise Price.






                                 Page 1 of 9
<PAGE>   80
         This Warrant may be exercised in whole or in part but not for
fractional Shares.  In case of the exercise in part only, the Company shall 
immediately deliver to the Holder a new Warrant of like tenor for the remaining
Shares.  This Warrant, at any time prior to the exercise hereof, upon 
presentation and surrender to the Company may be exchanged for another Warrant
or other Warrants of like tenor in the name of such Holder exercisable for the
same aggregate number of Shares as the Warrant or Warrants surrendered.

         3.      No Voting Rights.  This Warrant shall not entitle the Holder
hereof to any voting right (except as required by law) or to other rights as a
shareholder of the Company.  However, Holders of Shares received upon exercise
of this Warrant shall have such voting rights and all other rights as other
shareholders of the Company.

         4.      Covenants of the Company.  The Company hereby covenants and
agrees that prior to the expiration of this Warrant by exercise or by its
terms:

                 a.       The Company will not by amendment of its Certificate
of Incorporation or through reorganization, consolidation, merger, dissolution,
or sale of assets, or by any other voluntary act or deed, avoid or seek to
avoid the observance or performance of any of the covenants, stipulations or
conditions to be observed or performed hereunder by the Company, but will at
all times in good faith assist in the carrying out of all provisions of this
Warrant and in the taking of all other actions that may be necessary in order
to protect the rights of the Holder against dilution.

                 b.       The Company shall not issue any shares of common
stock or any other equity of the Company without the prior written consent of
Holder, and upon any such issuance, this Warrant shall be modified so that the
number of shares issuable hereunder shall represent the same percentage of the
fully diluted equity of the Company as before such issuance.

                 c.       The Company shall at all times reserve and keep
available, out of its authorized and unissued share capital, solely for the
purpose of providing for the exercise of the Warrant, forthwith upon the
request of the Holder of the Warrants then outstanding and in effect, such
numbers of Shares as shall, from time to time, be sufficient for the exercise
in full of the Warrants.  The Company shall, from time to time, in accordance
with the laws of the State of Delaware, increase the authorized amount of its
share capital if at any time the number of Shares remaining unissued and
unreserved for other purposes shall not be sufficient to permit the exercise of
the Warrants then outstanding and in effect.

         Notwithstanding the foregoing, the Company and the Holder acknowledge
that as of the date of this Warrant, the Company has 16,880,130 shares of
authorized and unissued shares of its common stock available for the purpose of
issue upon (1) the exercise, in whole, of the conversion rights of the Series A
11.75% Cumulative Convertible Preferred Stock of the Company (the "Series A
Preferred Stock") and the convertible secured notes issued pursuant to the
Convertible Debt Agreement  and (2) the exercise, in whole, of this Warrant,
the FLL Warrant, the Laport Warrant and the Amsterdam Warrant No. 2
(collectively, the "Other Warrants").  If the amount, of shares authorized
and unissued is insufficient, to effect, in whole, the conversion and/or
exercise in whole, of the Preferred Stock, the convertible secured notes
issued pursuant to the Convertible Debt Agreement, this Warrant and the
                                                                




                                 Page 2 of 9
<PAGE>   81
Other Warrants, (2) then, upon the request of the Holder, the Company shall 
take all actions necessary to increase the number of authorized shares in an 
amount sufficient to issue all shares issuable pursuant to the conversion rights
represented by the Convertible Secured Notes, the Series A Preferred Stock, and
the exercise of this Warrant and the Other Warrants.

         5.      Loss, Theft, Destruction or Mutilation.  In case this Warrant
shall become mutilated or defaced or be destroyed, lost or stolen, the Company
shall execute and deliver a new Warrant in exchange for and upon surrender and
cancellation of such mutilated or defaced Warrant or in lieu of and
substitution for such Warrant so destroyed, lost or stolen, upon the Holder of
such Warrant filing with the Company such reasonable evidence (an affidavit
shall suffice) that such Warrant has been so mutilated, defaced, destroyed,
lost or stolen and of the ownership thereof by the Holder; provided, however,
that the Company shall be entitled, as a condition to the execution and
delivery of such new Warrant, to demand reasonable indemnity and payment of
expenses and charges incurred in connection with the delivery of such new
Warrant, and may, if reasonable under the circumstances, request a bond from
the Holder.  All Warrants so surrendered to the Company shall be canceled.

         6.      Record Owner.  At the time of the surrender of this Warrant,
together with the payment of the Exercise Price, the person exercising this
Warrant shall be deemed to be the Holder of record of the Warrants deliverable
upon such exercise, in whole or in part, notwithstanding that the stock
transfer books of the Company shall then be closed or that certificates
representing such securities shall not then be actually delivered to such
person.

         7.      Fractional Securities.  No fractional Shares, fractional
warrants, fractional shares or scrip representing fractional shares shall be
issued upon the exercise of this Warrant.  With respect to any fraction of a
share called for on such exercise, the Holder may elect to remit to the Company
an amount in cash equal to the difference between such fraction and one,
multiplied by the Exercise Price, and the Company will issue the Holder one
Share in addition to the number of whole shares required by the exercise of the
Warrant.

         8.      Original Issue Taxes.  The Company shall pay all United
States, state, local and any other original issue taxes, if any, upon the
issuance of this Warrant or the Shares deliverable upon exercise hereof.

         9.      Notices.  All notices, requests and other communications
provided for hereunder shall be in writing and sent by first class or
equivalent mail of the country of origin, registered or certified, postage
prepaid and return receipt requested or delivered personally or by courier
against written acknowledgement of receipt (i) if to the Company, at 2358
Hassell Road, Hoffman Estates, Illinois 60195, with a copy to John F. Mahoney,
Esq., Chuhak & Tecson, 225 West Washington Street, Suite 1300, Chicago,
Illinois, 60606, (ii) if to the Holder, at the address designated for such
Holder on Exhibit A (unless otherwise indicated by Holder).  All such notices

         10.     Restrictions on Transferability.  The Warrant and the Shares
issuable upon exercise of this Warrant may be transferred by the Holder
pursuant to any applicable exemption from registration under the Securities Act
of 1933, as amended, or applicable state securities laws.

         Further, this Warrant, and the Shares issuable upon exercise of this
Warrant, have not yet been registered under the Securities Act.  Accordingly,
this Warrant, all replacement Warrants and the stock certificates representing
the Shares shall, prior to registration pursuant to the Registration Agreement,
bear the following legend:

         THIS WARRANT, AND THE SECURITIES ISSUABLE UPON THE EXERCISE OF THIS
         WARRANT, HAVE NOT BEEN REGISTERED EITHER UNDER THE SECURITIES ACT OF
         1933 OR ANY STATE SECURITIES LAW AND ANY TRANSFER THEREOF IS SUBJECT
         TO COMPLIANCE WITH SUCH LAWS AND THE TERMS OF THIS WARRANT.


         11.     Entire Agreement and Modification.  The Company and the Holder
of this Warrant hereby represent and warrant that, except for the provisions of
the Convertible Debt Agreement and that certain Registration Agreement, dated
as of April 22, 1996 by and between the Company and the Holder (which such
Registration Agreement is hereby incorporated herein and made a part hereof by
this reference thereto) this Warrant is intended to and does contain and embody
all of the understandings and agreements, both written and oral, of the Parties
with respect to the subject matter of this Warrant, and that there exists no
oral agreement or understanding, express or implied, whereby the absolute,
final and unconditional character and nature of this Warrant shall be in any
way invalidated, empowered or affected.  A modification or waiver of any of the
terms, conditions or provisions of this Warrant shall be effective only if made
in writing and executed with the same formality as this Warrant.

         12.     Authorization.  The undersigned have been duly authorized by
the Company to execute this Warrant, and any related agreements between the
Company and the Holder, the signatures of the undersigned are binding upon the
Company, and their execution of this Warrant does not constitute a breach of
any existing agreement to which the Company is a party.

         13.     Effective Date.  Warrants granted hereunder shall become
effective immediately upon the earliest to occur, for any reason whatsoever, of
any one or more of the following events: (i) an Event of Default other than the

to pay dividends on the Series A Preferred Stock which is due on June 30, 1996
or September 30, 1996 (it being acknowledged that failure to pay interest on
the Convertible Secured Note due at any other time shall be deemed an Event
of Default hereunder and thereunder), (ii) the failure of net income of the
Company for 1996, determined in accordance with generally accepted 
accounting principles applied on a basis consistent with past periods, to be
at least One United States Dollar ($1.00), (iii) the failure of net income of

owed under the Convertible Secured Notes outstanding at the end of 1997, 
and/or (iv) for every year after 1997, the failure of net income of the 
Company, determined in accordance with generally accepted accounting principles
applied on a basis consistent with past periods, to increase no less than the 
total of Ten Percent (10.0%) per year, on a compounded basis, plus Sixty 
Percent (60.0%) of the increase in dollar amount of principal and interest owed
under the Convertible Secured Notes outstanding at the end of any such year 
over the immediately preceding year.  The Company must provide written notice
to the Holder of the occurrence of any of events set forth in the immediately 
preceding sentence no later that thirty (30) days after any such occurrence.  
The Warrants granted hereunder shall be wholly void and of no effect and the 
rights evidenced hereby will terminate unless exercised in accordance with the 
terms and provisions hereof before the date set forth in Section 2.

         3.      No Voting Rights.  This Warrant shall not entitle the Holder
hereof to any voting right (except as required by law) or to other rights as a

of Incorporation or through reorganization, consolidation, merger, dissolution,
or sale of assets, or by any other voluntary act or deed, avoid or seek to
avoid the observance or performance of any of the covenants, stipulations or
conditions to be observed or performed hereunder by the Company, but will at
all times in good faith assist in the carrying out of all provisions of this
Warrant and in the taking of all other actions that may be necessary in order
to protect the rights of the Holder against dilution.

                 b.       The Company shall at all times reserve and keep

purpose of providing for the exercise of the Warrant, forthwith upon the
request of the Holder of the Warrants then outstanding and in effect, such
numbers of Shares as shall, from time to time, be sufficient for the exercise
in full of this Warrant.  The Company shall, from time to time, in accordance
with the laws of the State of Delaware, increase the authorized amount of its
share capital if at any time the number of Shares remaining unissued and
unreserved for other purposes shall not be sufficient to permit the exercise of
this Warrant then outstanding and in effect.

         Notwithstanding the foregoing, the Company and the Holder acknowledge
that as of the date of this Warrant, the Company has 100 shares of authorized
and unissued shares of its Series B Preferred Stock available for the purpose

of such Warrant filing with the Company such reasonable evidence (an affidavit
shall suffice) that such Warrant has been so mutilated, defaced, destroyed,
lost or stolen and of the ownership thereof by the Holder; provided, however,
that the Company shall be entitled, as a condition to the execution and
delivery of such new Warrant, to demand reasonable indemnity and payment of
expenses and charges incurred in connection with the delivery of such new
Warrant, and may, if reasonable under the circumstances, request a bond from
the Holder.  All Warrants so surrendered to the Company shall be canceled.

         6.      Record Owner.  At the time of the surrender of this Warrant,
together with the payment of the Exercise Price, the person exercising this
Warrant shall be deemed to be the Holder of record of the Warrants deliverable
upon such exercise, in whole or in part, notwithstanding that the stock
transfer books of the Company shall then be closed or that certificates
representing such securities shall not then be actually delivered to such
person.

issuance of this Warrant or the Shares deliverable upon exercise hereof.

communications shall be effective on the date of delivery to the party
receiving such notice, as evidenced by the date set forth on the receipt signed
by the party receiving such notice.

         9.      Restrictions on Transferability.  The Warrant and the Shares
issuable upon exercise of this Warrant may be transferred by the Holder
pursuant to any applicable exemption from registration under the Securities Act
of 1933, as amended, or applicable state securities laws.

         Further, this Warrant, and the Shares issuable upon exercise of this
Warrant, have not yet been registered under the Securities Act.  Accordingly,

understandings and agreements, both written and oral, of the Parties with
respect to the subject matter of this Warrant, and that there exists no oral

Company, and their execution of this Warrant does not constitute a breach of
any existing agreement to which the Company is a party.

         12.     Effective Date.  Warrants granted hereunder shall become
effective immediately.  The Warrants granted hereunder shall be wholly void and
of no effect and the rights evidenced hereby will terminate unless exercised in
accordance with the terms and provisions hereof before the dates set forth in
Section 2.

                          (c)     Registrable Securities:  The term
                 "Registrable Securities" shall be defined as: (i) any and all
                 shares of Common Stock of the Company issued pursuant to the
                 terms of the Convertible Debt Agreement including, without
                 limitation, (A) all shares of Common Stock of the Company
                 obtained as a result of the conversion of convertible debt
                 pursuant to the terms of Section 3.1 of the Convertible Debt
                 Agreement, and (B) all shares of Common Stock of the Company
                 obtained as a result of the provisions set forth in Section
                 8.4 of the Convertible Debt Agreement; (ii) any shares of
                 Common Stock of the Company issued pursuant to the terms of
                 that certain Warrant To Purchase Up To 3,588,750 Unregistered
                 Shares Of Common Stock Of Princeton Dental Management
                 Corporation dated as of April 22, 1996; and (iii) any
                 securities issued or issuable in respect to securities
                 included in foregoing items (i)-(ii) (the "Primary
                 Securities") by way of any distribution of securities or
                 pursuant to any stock dividend, stock split or combination,
                 recapitalization, merger, consolidation, or other
                 reorganization of the Company affecting the Primary
                 Securities.  For purposes of this Agreement, a Person will be
                 deemed to be a holder of Registrable Securities whenever such
                 Person has the right to acquire such Registrable Securities
                 (upon conversion or exercise in connection with a transfer of
                 securities or otherwise, but disregarding any restrictions or
                 limitations upon the exercise of such right), whether or not
                 such acquisition has actually been effected.

         2.      Registration Rights.  At any time and from time to time after
the date hereof, the Company shall file and use its best efforts to
cause to become effective a registration statement to register any and all
Registrable Securities under the Act (a "Demand Registration") when and as
directed by the then holders of a majority of the Registrable Securities.  Each
written request for a registration shall specify the approximate number of
Registrable Securities requested to be registered, the identity of the holders
of Registrable Securities demanding such registration, the form such
registration is to be effected on and the anticipated per share price range for
such offering.  Within ten (10) days after receipt of notice of registration,
the Company shall give written notice of such demand to all other holders of
Registrable Securities.  The Company will include in such registration all
Registrable Securities with respect to which the Company has received written
requests for inclusion therein within twenty (20) days after the date of the
Company's notice of the registration to holders of Registrable Securities.  The
Company shall file and use its best efforts to cause to become effective a
registration statement covering all Registrable Securities to be so registered
under the Act no later than the ninetieth (90th) calendar day from the date of
the original notice to the Company.  If the Company is unable to so register
such Registrable Securities within ninety (90) calendar days, then the Company
shall issue pro rata to each holder of Registrable Securities who had requested
such registration additional shares of Common Stock (which shall be Registrable
Securities) in the amount equal to the product of (i) the number of Registrable
Securities requested to be registered by such holder, and (ii) the difference
between the fair market value of a share of Common Stock on the business day
immediately following the ninetieth (90th) calendar day after which the notice
to register was delivered (as determined by the average of the NASDAQ high and
low sales price on such business day (or whatever market quotation as may be
relevant at the time)) and the fair market value of a share of Common Stock on
the business day immediately following the effective date of the registration
statement (as defined in Section 3(l)) covering such shares of Common Stock (as
determined by the average of the NASDAQ high and low sales price per share on
such day (or whatever market quotation as may be relevant at the time));
provided, however, that if the fair market value of such a share has, in such
instance, increased, the Company shall not be required to grant to the holders
of Registrable Securities then registering their





                                 Page 2 of 13
<PAGE>   96
shares any additional shares of Common Stock; further, provided, that
in no event shall any holder of Registrable Securities ever be required to
return any shares of Common Stock to the Company pursuant to the terms hereof. 
Once any registration pursuant to this Section 2 is commenced, the Company
shall use its best efforts to complete such registration as expeditiously as
possible.  All expenses incurred in connection with such registration shall be
paid by the Company as provided in Section 4 herein.

                 In the event any securities to be sold by holders of
Registrable Securities pursuant to a registration under this Section 2 are not
sold in accordance with the plan of distribution set forth in the registration
statement within nine (9) months after the effective date of the registration
statement, then such shares shall be deemed not to have been registered
pursuant to Section 2 and shall remain Registrable Securities.

                 Nothing in this Agreement shall be deemed to require any
holder of Registrable Securities to exercise its rights of conversion with
respect to, or its rights to acquire, any Registrable Securities, either as a
condition to demanding or requesting registration hereunder or at any other
time.

         3.      Registration Procedures.  No later than the applicable date
referenced in Section 2 herein for registration of the Registrable Securities,
the Company shall register such Registrable Securities in accordance with the
intended method of disposition thereof and pursuant thereto the Company shall:

                 (a)      prepare and file with the Securities and Exchange
         Commission ("SEC") a registration statement on such form as the
         holders of a majority of the Registrable Securities shall specify and
         which the Company shall be permitted to use with respect to such
         Registrable Securities and use its best efforts to cause such
         registration statement to become effective (provided that before
         filing a registration statement or prospectus or any amendments or
         supplements thereto, the Company shall furnish to the counsel selected
         by the holders of a majority of the Registrable Securities copies of
         all such documents proposed to be filed a reasonable time prior to
         filing, which documents shall be subject to the review and comment of
         such counsel and the inclusion of such material as such counsel may
         reasonably request);

                 (b)      prepare and file with the SEC such amendments and
         supplements to such registration statement and the prospectus used in
         connection therewith as may be necessary to (i) keep such registration
         statement effective for a period of not less than nine (9) calendar
         months and (ii) comply with the provisions of the Act with respect to
         the disposition of all securities covered by such registration
         statement during such period in accordance with the intended methods
         of disposition by the sellers thereof set forth in such registration
         statement;
 
                 (c)     furnish to each holder of Registrable
         Securities and the underwriters, if any, such number of copies
         of such registration statement, each amendment and supplement thereto,
         the prospectus included in such registration statement (including each
         preliminary prospectus) and such other documents as such holder may
         request in order to facilitate the disposition of the Registrable
         Securities owned by such holder;

                (d)      use its best efforts to register or qualify such
         Registrable Securities under such other securities or blue sky laws of
         such jurisdictions as any holder requests and do any and all





                                 Page 3 of 13
<PAGE>   97
         other acts and things which may be reasonably necessary or advisable to
         enable such holder to consummate the disposition in such jurisdictions
         of the Registrable Securities owned by such holder (provided that the
         Company will not be required to (i) qualify generally to do business
         in any jurisdiction where it would not otherwise be required to
         qualify but for this subparagraph, (ii) subject itself to taxation in
         any such jurisdiction or (iii) consent to general service of process
         in any such jurisdiction);

                 (e)      notify each holder of such Registrable Securities, at
         any time when a prospectus relating thereto is required to be
         delivered under the Act, of the receipt by the Company of any
         notifications with respect to suspension of the qualification of the
         Registrable Securities for sale in any jurisdiction or the initiation
         or threatening of any proceeding for such purpose or of the happening
         of any event known to the Company as a result of which the prospectus
         included in such registration statement contains an untrue statement
         of a material fact or omits any material fact necessary to make the
         statements therein not misleading, and, at the request of any such
         holder, the Company shall prepare a supplement or amendment to such
         prospectus so that, as thereafter delivered to the purchasers of such
         Registrable Securities, such prospectus shall not contain an untrue
         statement of a material fact or omit to state any material fact
         necessary to make the statements therein not misleading;

                 (f)      cause all such Registrable Securities to be listed on
         each securities exchange or quoted on each interdealer quotation
         system on which similar securities issued by the Company are then
         listed or quoted, or if similar securities are not then listed or
         quoted, to cause such securities to become listed or quoted prior to
         the sale of Registrable Securities pursuant to the registration
         hereunder;

                 (g)      provide a transfer agent and registrar for all such
         Registrable Securities not later than the effective date of such
         registration statement and facilitate the timely preparation and
         delivery of certificates representing the Registrable Securities to be
         sold under the registration statement, in such denominations and
         registered in such names as the managing underwriter or underwriters,
         if any, or the holders of Registrable Securities may request;

                 (h)      enter into such customary and reasonable agreements
         (including underwriting agreements in customary and reasonable form)
         and take all such other actions as the holders of a majority of the
         Registrable Securities, or the underwriters, if any, reasonably
         request in order to expedite or facilitate the disposition of such
         Registrable Securities (including, without limitation, effecting a
         stock split or a combination of shares);

                 (i)     make available for inspection by any holder of
         Registrable Securities, any underwriter participating in any
         disposition pursuant to such registration statement, and any attorney,
         accountant or other agent retained by any such holder or underwriter,
         all financial and other records, pertinent corporate documents and
         properties of the Company as may be reasonably requested, and cause
         the Company's officers, directors, employees and independent
         accountants to supply all information reasonably requested by any such
         holder, underwriter, attorney, accountant or agent in connection with
         such registration statement;





                                 Page 4 of 13
<PAGE>   98
                 (j)      use its best efforts to cause such Registrable
         Securities covered by such registration statement to be registered
         with or approved by such other governmental agencies or authorities as
         may be reasonably necessary to enable the holders thereof to
         consummate the disposition of such Registrable Securities;

                 (k)      obtain for the benefit of the holders of Registrable
         Securities and the underwriters, if any, a comfort letter from the
         Company's independent public accountants and a legal opinion from the
         Company's counsel, each in customary and reasonable form and covering
         such matters of the type customarily and reasonably covered by comfort
         letters and legal opinions as the holders of a majority of the
         Registrable Securities reasonably request;

                 (l)      otherwise use its reasonable efforts to comply in all
         material respects with all applicable rules and regulations of the
         SEC, and make available to its security holders, as soon as reasonably
         practicable, an earnings statement covering the period of at least
         twelve (12) months beginning with the first month after the "effective
         date of the registration statement" (as determined in accordance with
         the provisions of Rule 158(c) of the Act), which earnings statement
         shall satisfy the provisions of Section 11(a) of the Act and Rule 158
         thereunder;

                 (m)      permit any holder of Registrable Securities which
         holder, in its sole and exclusive judgment, might be deemed to be an
         underwriter or a controlling person of the Company, to participate in
         the preparation of such registration or comparable statement and to
         require the insertion therein of material, furnished to the Company in
         writing, which in the reasonable judgment of such holder and its
         counsel should be included; and

                 (n)      in the event of the issuance of any stop order
         suspending the effectiveness of a registration statement, or of any
         order suspending or preventing the use of any related prospectus or
         suspending the qualification of any Registrable Securities included in
         such registration statement for sale in any jurisdiction, the Company
         will use its reasonable efforts promptly to obtain the withdrawal of
         such order.

        If any such registration or comparable statement refers to any holder
of Registrable Securities by name or otherwise as the holder of any securities
of the Company and if in its sole and exclusive judgment, such holder is or
might be deemed to be a controlling person of the Company, such holder shall
have the right to require the insertion therein of language, in form and
substance satisfactory to such holder and presented to the Company in writing,
to the effect that the holding by such holder of such securities is not to be
construed as a recommendation by such holder of the investment quality of the
Company's securities covered thereby and that such holding does not imply that
such holder will assist in meeting any future financial requirements of the
Company.

         4.      Registration Expenses.  All expenses incident to the Company's
performance of or compliance with this Agreement, including without limitation
all registration and filing fees, fees and expenses of compliance with
securities or blue sky laws, printing expenses, messenger and delivery
expenses, and fees and disbursements of counsel for the Company and all
independent certified public accountants, underwriters (excluding discounts and
commissions) and other persons retained by the Company (all such expenses being
herein called "Registration Expenses"), shall be borne in their entirety


                                 Page 5 of 13
<PAGE>   99
by the Company; provided, that the Company shall, in addition, pay its
internal expenses (including, without limitation, all salaries and expenses of
its officers and employees performing legal or accounting duties), the expense
of any annual audit or quarterly review, the expense of any liability insurance
(relating exclusively to any such liability insurance in effect as of the date
hereof) and the expenses and fees for listing the securities to be registered
on each securities exchange or interdealer quotation system on which similar
securities issued by the Company are then listed.

         5.      Indemnification.

                 (a)      The Company agrees to indemnify each holder of
         Registrable Securities covered by such registration statement, its
         officers, directors, partners, stockholders, employees, agents,
         trustees and each Person who controls such holder (within the meaning
         of the Act) against all losses, claims, damages, liabilities and
         expenses or amounts paid in settlement caused by (i) any violation or
         alleged violation of federal or state securities laws caused by the
         execution or implementation of this Agreement and (ii) any untrue or
         alleged untrue statement of material fact contained in any
         registration statement, prospectus or preliminary prospectus or any
         amendment thereof or supplement thereto or any omission or alleged
         omission of a material fact required to be stated therein or necessary
         to make the statements therein not misleading, except insofar as the
         same are caused by or contained in any information furnished in
         writing to the Company by such holder expressly for use therein or by
         such holder's failure to deliver a copy of the registration statement
         or prospectus or any amendments or supplements thereto after the
         Company has furnished such holder with sufficient number of copies of
         the same.  In connection with an underwritten offering, the Company
         will indemnify such underwriters, their officers and directors and
         each Person who controls such underwriters (within the meaning of the
         Act) to the same extent as provided above with respect to the
         indemnification of the holders of Registrable Securities.  The
         payments required by this Section 5(a) will be made periodically
         during the course of the investigation or defense, when and as bills
         are received or expenses incurred.

                 (b)      In connection with any registration statement in
         which a holder of Registrable Securities is participating, each
         such holder will furnish to the Company in writing such information
         and affidavits as the Company reasonably requests for use in
         connection with any such registration statement or prospectus and, to
         the extent permitted by law, will indemnify the Company, its director
         and officers and each person who controls the Company (within the
         meaning of the Securities Act) against any losses, claims, damages,
         liabilities and expenses resulting from any untrue or alleged untrue
         statement of material fact contained in the egistration statement,
         prospectus or preliminary prospectus or any amendment thereof or
         supplement thereto, or any omission or alleged omission of a material
         fact required to be stated therein or necessary to make the statements
         therein not misleading, but only to the extent that such untrue
         statement or omission is contained in any information or affidavit so
         furnished in writing by such holder; provided that such obligation to
         indemnify will be several, not joint and several, among such holders
         of Registrable Securities and the liability of each such holder will
         be in proportion to and limited to the net amount received by such
         holder from the sale of Registrable Securities pursuant to such
         registration statement.




                                 Page 6 of 13
<PAGE>   100
                 (c)      Any Person (an "Indemnified Person") entitled to
         indemnification hereunder will (i) give prompt written notice to the
         party against whom indemnification is sought (the "Indemnifying
         Person") of any claim with respect to which it seeks indemnification
         (but the failure to provide such notice shall not release the
         Indemnifying Person of its indemnification obligations hereunder,
         unless the Indemnifying Person has been prejudiced by such failure to
         provide such notice and then only to the extent of such prejudice) and
         (ii) unless in such Indemnified Person's reasonable judgment, a
         conflict of interest between such Indemnified Person and the
         Indemnifying Person may exist with respect to such claim, permit the
         Indemnifying Person to assume the defense of such claim with counsel
         reasonably satisfactory to the Indemnified Person, provided that the
         Indemnifying Person does so diligently and in good faith.  If such
         defense is assumed, the Indemnifying Person will not be subject to any
         liability for any settlement made by the Indemnified Person without
         the Indemnifying Person's consent (but such consent will not be
         unreasonably withheld).  An Indemnifying Person who is not entitled
         to, or elects not to, assume the defense of a claim will not be
         obligated to pay the fees and expenses of more than one (1) counsel
         for all parties indemnified by the Indemnifying Person with respect to
         such claim, unless in the reasonable judgment of any Indemnified
         Person, a conflict of interest may exist between such Indemnified
         Person and any other Indemnified Person with respect to such claim.

                 (d)      The indemnification provided for under this Agreement
         shall remain in full force and effect regardless of any investigation
         made by or on behalf of the indemnified party or any officer,
         director, shareholder or controlling person of such indemnified party
         and shall survive the transfer of securities.

                 (e)      The Company also agrees to make such provisions, as
         are reasonably requested by any indemnified party, for contribution to
         such party in the event the Company's indemnification is unavailable
         for any reason.

         6.      Selection of Underwriters.  The holders of a majority of the
Registrable Securities included in any registration shall have the right to
select the investment banker(s) and manager(s) to administer the offering,
subject to the Company's approval which will not be unreasonably withheld.

         7.      Participation in Underwritten Registrations.  No person may
participate in any registration hereunder which is underwritten unless
such person (a) agrees to sell such person's securities on the basis provided
in any underwriting arrangements reasonably suggested by the Company's
underwriters and (b) completes and executes all questionnaires, powers of
attorney, indemnities, underwriting agreements and other documents reasonably
required under the terms of such underwriting arrangements not inconsistent
with this Agreement. The provisions of this Section shall in no way limit any
holder's of Registrable Securities rights pursuant to this Agreement to
registration hereunder in a non-underwritten registration.

         8.      Priority on Demand Registrations.  The Company will not
include in any registration hereunder any securities which are not Registrable
Securities without the prior written consent of the holders of a majority of
the Registrable Securities included in such registration.  If a registration
hereunder is an underwritten offering and the managing underwriters advise the
Company in writing that





                                 Page 7 of 13
<PAGE>   101
in their opinion the number of Registrable Securities and, if permitted
hereunder, other securities requested to be included in such offering exceeds
the number of Registrable Securities and other securities, if any, which can be
sold in such offering, without adversely affecting the marketability of the
offering, the Company will include in such registration in the case of a
registration requested by the holders of a majority of the Registrable
Securities, (x) first, the Registrable Securities requested to be included in
such registration, (y) second, other securities issued pursuant to the terms
and provisions of the Preferred Stock Purchase Agreement which any of the Other
Stockholders requests to be included in such registration, and (z) third, other
securities requested to be included in such registration.

Unless otherwise agreed by the Company, any Persons other than holders of
Registrable Securities who participate in Demand Registrations must pay their
share of the Registration Expenses as provided in Section 4.

         9.      Security Issuance, Other Registration Rights.  Except as
provided in this Agreement, the Convertible Debt Agreement, or the Preferred
Stock Purchase Agreement, the Company will not (i) issue or sell any of its
securities of any kind, (ii) register any of its securities for sale under the
Act or any state securities law or (iii) grant to any Persons the right to
request or require the Company to register any equity securities of the
Company, or any securities convertible or exchangeable into or exercisable for
such securities, without the prior written consent of the holders of a majority
of Registrable Securities; provided that the Company may grant rights to other
Persons to (i) participate in Piggyback Registrations so long as such rights
are subordinate to the rights of the holders of Registrable Securities with
respect to such Piggyback Registrations and (ii) request registrations so long
as the holders of Registrable Securities are entitled to participate in any
such registrations with such Persons pro rata on the basis of the number of
shares owned by each such holder and any such registration is subject to the
approval of the holders of a majority of the Registrable Securities.

         10.     Piggyback Registrations.

                 (a)      Right to Piggyback.  Whenever the Company proposes to
         register any of its securities under the Act (other than
         pursuant to a registration hereunder) as permitted by Section 9 and
         the registration form to be used may be used for the registration of
         Registrable Securities (a "Piggyback Registration"), the Company will
         give prompt written notice to all holders of Registrable Securities of
         its intention to effect such a registration at least thirty (30) days
         prior to the anticipated filing date of the registration statement
         relating to such registration.  Such notice will offer the holders of
         Registrable Securities the opportunity to include in such registration
         statement such Registrable Securities as each holder may request in
         writing within twenty (20) days after the receipt of the Company's
         notice. Except as provided in paragraphs 10(c), 10(d) and 10(e) below,
         the Company shall include in any such registration statement all such
         Registrable Securities requested to be included.

                 (b)      Piggyback Expenses.  The Registration Expenses of the
         holders of Registrable Securities will be paid by the Company in all
         Piggyback Registrations.

                 (c)      Priority on Primary Registrations.  If a Piggyback
         Registration is an underwritten primary registration on behalf of the
         Company, and the managing underwriters advise the 






                                 Page 8 of 13
<PAGE>   102
         Company in writing that in their opinion the number of
         securities requested to be included in such registration exceeds the
         number which can be sold in such offering without adversely affecting
         the marketability of the offering, the Company will include in such
         registration (i) first, the securities the Company proposes to sell,
         (ii) second, the Registrable Securities requested to be included in
         such registration and (iii) third, other securities requested to be
         included in such registration.

                 (d)      Priority on Secondary Registrations.  Except as
         otherwise provided in Section 8 hereof, if a Piggyback Registration is
         an underwritten primary registration other than on behalf of the
         Company, and the managing underwriters advise the Company in writing
         that in their opinion the number of securities requested to be
         included in such registration exceeds the number which can be sold in
         such offering without adversely affecting the marketability of the
         offering, the Company will include in such registration the securities
         requested to be included in such registration reduced pro rata in
         accordance with the original number of securities requested to be
         included.

                 (e)      Withdrawal by Company.  If, at any time after giving
         written notice of its intention to register any of its securities as
         set forth in Section 10(a) and prior to the effective date of the
         registration statement filed in connection with such registration, the
         Company shall determine for any reason not to register such
         securities, the Company may, at its election, given written notice of
         such determination to each holder of Registrable Securities and
         thereupon shall be relieved of its obligation to register any
         Registrable Securities in connection with such registration (but not
         from its obligation to pay the Registration Expenses in connection
         therewith as provided herein).

         11.     Other Registrations.  If the Company has previously filed a
registration statement with respect to Registrable Securities pursuant to
Section 2 or Section 10, and if such previous registration has not been
withdrawn or abandoned, the Company will not file or cause to be effected any
other registration of any of its equity securities or securities convertible or
exchangeable into or exercisable for its equity securities under the Act
(except on Form S-8 or any successor form), whether on its own behalf or at the
request of any holder or holders of such securities, until a period of at least
nine (9) months has elapsed from the effective date of such previous
registration, unless a shorter period of time is approved by the holders of a
majority of Registrable Securities included in such registration.


         12.     Holdback Agreements.  Notwithstanding the provisions of
Section 9, the Company agrees (i) not to effect any public sale or distribution
of its equity securities, or any securities convertible into or exchangeable or
exercisable for such securities, during the thirty (30) days prior to and
during the 270-day period beginning on the effective date of any underwritten
registration hereunder or any underwritten Piggyback Registration (except as
part of such underwritten registration or pursuant to registrations on Form S-8
or any successor form), unless the underwriters managing the registered public
offering otherwise agree, and (ii) to cause each holder of at least 5% (on a
fully- diluted basis) of its Common Stock, or any securities convertible into
or exchangeable or exercisable for Common Stock, purchased from the Company at
any time after the date of this Agreement (other than in a registered public
offering) to agree not to effect any public sale or distribution (including
sales pursuant to Rule


                                 Page 9 of 13
<PAGE>   103
144) of any such securities during such period (except as part of such
underwritten registration, if otherwise permitted), unless the underwriters
managing the registered public offering otherwise agree.

         13.     Creditor Standstill.  During the 270-day period beginning on
the effective date of any underwritten registration pursuant to Section 2
hereof, the Stockholder shall not make any demands for registration pursuant to
Section 2 hereof.  During the 180-day period beginning on the effective date of
any underwritten registration pursuant to Section 2 of the Other Registration
Agreement, the Stockholder shall not make any demand for registration pursuant
to Section 2 hereof.

         14.     Stock Legends.  When and to the extent permitted by the Act,
the Company shall provide to the holders of Registrable Securities, at no cost
or expense to such holders, equivalent stock certificates without restrictive
legends of any kind to evidence that their shares of the Company's Common Stock
are not restricted securities under the Act.

         15.     Current Public Information.  The Company shall use its best
efforts to file the reports required to be filed by it under the Act and the
Securities Exchange Act of 1934, as amended, and the rules and regulations
promulgated thereunder, (or, if the Company is not required to file such
reports, it shall, upon the request of the holders of a majority of the
Registrable Securities, use its best efforts to make publicly available
sufficient information, for so long as necessary, to permit sales under Rule
144 under the Act), and it shall use its best efforts to take such further
action as the holders of a majority of the Registrable Securities may
reasonably request, all to the extent required from time to time to enable the
holders of a majority of the Registrable Securities to sell the Registrable
Securities, without registration under the Act within the limitation of the
exemptions provided by (a) Rule 144 under the Act, as such Rule may be amended
from time to time, or (b) any similar rule or regulation hereafter adopted by
the SEC.   Upon the request of the holders of a majority of the Registrable
Securities, the Company will deliver to the holders of a majority of the
Registrable Securities a written statement as to whether it has complied with
such requirements.

         16.     Miscellaneous.

                 (a)      Remedies.  Any person having rights under any
         provision of this Agreement shall be entitled to enforce such rights
         specifically, to recover damages caused by reason of any breach of any
         provision of this Agreement and to exercise all other rights granted
         by law.


                 (b)     Amendments and Waivers.  The Company may agree to an
         amendment of the provisions of this Agreement and the Company may take
         any action herein prohibited, or omit to perform any act herein
         required to be performed by it, only if the Company has obtained the
         written consent of holders of at least a majority of the Registrable
         Securities.

                 (c)      Successors and Assigns.  All covenants and agreements
         in this Agreement by or on behalf of any of the Parties shall bind and
         inure to the benefit of the respective successors and assigns of the
         Parties whether so expressed or not.

                 (d)      Notices.  Any notice provided for in this Agreement
         must be in writing and must be either personally delivered or by

                                Page 10 of 13
<PAGE>   104
         by registered mail, postage prepaid and return receipt
         requested, to the Company at Princeton Dental Management Corporation,

         Convertible Debt Agreement, or, if changed by the Stockholder
         hereafter by notice from such Stockholder to the Company in accordance
         with the provisions set forth herein, at said new address provided by
         such Stockholder to the Company.  Notice pursuant to this Section
         shall be deemed received on the date of delivery to the party
         receiving such notice as evidenced by the date set forth on the
         receipt signed by the party receiving such notice.

                 (e)      Governing Law.  All questions concerning the
         construction, validity and interpretation of this Agreement will be

assigned to such terms in the Debt Agreement.

         B.  It is a condition precedent to Lender's entering into the Debt

Mason Southeast, Midwest, Northeast and Southwest (each a "GUARANTOR" and,
collectively, the "GUARANTORS") execute and deliver this Guaranty.

         C.  Each Guarantor acknowledges that, in view of the business and
economic relationship that exists between Borrower and such Guarantor, (I) the

<PAGE>   110
         SECTION 1.  GUARANTY.  Guarantors unconditionally and absolutely,
jointly and severally, guarantee the full and prompt payment, performance and
observance when due, whether at maturity or earlier by reason of acceleration
or otherwise, and at all times thereafter, of all of the Liabilities
(including, without limitation, interest accruing thereon following the filing
by or against Borrower of any bankruptcy or similar insolvency proceedings,
whether or not allowed as a claim in any such proceeding).  At any time after
the occurrence of an Event of Default, and during the continuance thereof,
Guarantors shall jointly and severally pay to Lender, on demand and in
immediately available funds, the full amount of the Liabilities which are due
and payable at such time.  Guarantors, jointly and severally, further agree to
pay all costs and expenses, including, without limitation, all court costs and
reasonable attorneys' and paralegals' fees and expenses, paid or incurred by
Lender in endeavoring to collect all or any part of the Liabilities from, or in
prosecuting any action against, any Guarantor.  This Guaranty is an absolute
guaranty of payment and performance and not a guaranty of collection.

         SECTION 2.  GUARANTY ABSOLUTE.  Each Guarantor hereby agrees that its
obligations under this Guaranty shall be unconditional, irrespective of (I) the
validity or enforceability of all or any part of the Liabilities or of any
promissory note or other agreement, document or instrument evidencing all or
any part of the Liabilities, (II) the absence of any attempt to collect the
Liabilities from Borrower, any Guarantor or any other guarantor or other action
to enforce the same, (III) the waiver or consent by Lender with respect to any
provision of any instrument evidencing the Liabilities, or any part thereof, or
any other agreement or document now or hereafter executed by Borrower and
delivered to Lender, (IV) failure by Lender to take any steps to perfect and
maintain its security interest in, or to preserve its rights to, any collateral
security for the Liabilities, (V) Lender's election, in any proceeding
instituted under Chapter 11 of the United States Bankruptcy Code, as amended,
11 U.S.C. Section 101 et. seq. (the "BANKRUPTCY CODE") of the application of
Section 1111(b)(2) of the Bankruptcy Code, (VI) any borrowing or grant of a
security interest by Borrower, as a debtor-in-possession, under Section 364 of
the Bankruptcy Code, (VII) the disallowance, under Section 502 of the
Bankruptcy Code, of all or any portion of Lender's claim(s) for repayment of
the Liabilities, (VIII) the election of any remedy by, or on behalf of, Lender
with respect to all or any part of the Liabilities, (IX) any act or omission of
Lender which changes the scope of such Guarantor's risk, (X) any errors or
omissions in connection with Lender's administration of the Liabilities, or
(XI) any other circumstance which might otherwise constitute a legal or
equitable discharge or defense of a guarantor or surety of or for Borrower.

<PAGE>   111
         SECTION 3.       GRANT OF SECURITY.  To secure the prompt payment,
observance and performance of the Liabilities, each Guarantor hereby grants to
Lender a continuing security interest in and to the following property and
interests in property of such Guarantor, whether now owned and existing or
hereafter acquired or arising, and wheresoever located:  accounts, contract
rights, chattel paper, instruments, documents, inventory (including, without
limitation, work-in-process), general intangibles (including, without
limitation, general or limited partnership interests, inventions, designs,
patents, patent applications, trademarks, trademark applications, trade names,
trade secrets, goodwill, licenses, franchises, tax refund claims, guaranty
claims, rights and claims against shippers and carriers, and security interests
or other collateral security held by such Guarantor), tax refunds, rights to
other refunds and indemnification, equipment, machinery, tools, spare parts,
furniture and fixtures together with all accessions and additions to, products,
replacements and proceeds of (including, without limitation, proceeds of
insurance policies insuring the same), and substitutions for any of the
foregoing property and interests in property and all of such Guarantor's books
and records related to any of the foregoing property (all such property and
interests in property of any Guarantor being the "COLLATERAL" of such
Guarantor); provided, however, that, notwithstanding the foregoing, the
Collateral of each Guarantor shall not include any rights or interest of such
Guarantor Management Agreement (as defined below) if (and solely to the extent
and for so long as) such Management Agreement expressly prohibits such
Guarantor from granting to the Lender any Lien on any rights or interests of
such Guarantor thereunder.  For purposes hereof, "EXISTING MANAGEMENT
AGREEMENTS" means the agreements set forth on ANNEX 1 hereto.  The security
interest granted hereinabove by each Guarantor shall be a continuing security
interest in the Collateral of such Guarantor and shall remain in full force and
effect until indefeasible payment and satisfaction in full of the Liabilities
and termination of the Debt Agreement and this Guaranty pursuant to the
respective terms and provisions thereof and hereof.

         SECTION 4.  FURTHER ASSURANCES.  Each Guarantor hereby agrees to
execute and deliver to Lender such financing statements and amendments and
supplements thereto, and such other instruments as Lender may from time to time
request (and will pay all costs and expenses of recording the same) in order to
perfect, preserve, protect and maintain the security interest hereby granted by
such Guarantor.  Each Guarantor further agrees that a carbon, photographic,
photostatic or other reproduction of this Guaranty or of a financing statement
is sufficient as a financing statement with respect to the Collateral of such
Guarantor.





                                 Page 3 of 15
<PAGE>   112
         SECTION 5.  WAIVER; DISCHARGE ONLY BY COMPLETE PERFORMANCE;
ENFORCEMENT; APPLICATION OF PAYMENTS.  Each Guarantor hereby waives diligence,
presentment, demand of payment, filing of claims with a court in the event of
receivership or bankruptcy of Borrower, protest or notice with respect to the
Liabilities and all other demands whatsoever.  Each Guarantor also waives all
setoffs and counterclaims and all presentments, demands for performance,
notices of nonperformance, protests, notices of protest, notices of dishonor,
notices of acceptance of this Guaranty, and the benefits of all statutes of
limitation.  Each Guarantor further waives all notices of the existence,
creation or incurring of new or additional Liabilities, arising either from
additional loans extended to Borrower or otherwise, and also waives all notices
that the principal amount, or any portion thereof, and/or any interest on, any
instrument or document evidencing all or any part of the Liabilities is due,
notices of any and all proceedings to collect from the maker, any endorser or
any other guarantor of all or any part of the Liabilities, including any other
Guarantor, or from any other Person, and, to the extent permitted by law,
notices of exchange, sales, surrender or other handling of any collateral
security given to Lender to secure payment of all or any part of the
Liabilities.  Each Guarantor still further waives all defenses based on lack of
consideration, breach of warranty, statute of frauds, accord and satisfaction,
and usury.  EACH GUARANTOR COVENANTS AND EXPRESSLY AGREES THAT THIS GUARANTY
WILL NOT BE DISCHARGED, EXCEPT BY COMPLETE PAYMENT AND PERFORMANCE OF THE
OBLIGATIONS SET FORTH HEREIN.  Upon the occurrence and during the continuance
of an Event of Default, Lender may proceed directly and at once, without
notice, against any or all of the Guarantors to collect and recover the full
amount or any portion of the Liabilities, without first proceeding against
Borrower or any other Person, or against any collateral security for the
Liabilities.  Lender shall have the exclusive right to determine the
application of payments and credits, if any, from each Guarantor, Borrower or
from any other Person on account of the Liabilities or of any other liability
of Borrower or any Guarantor to Lender.

         SECTION 6.  COLLECTION FROM EACH GUARANTOR; SALE OF COLLATERAL.  Upon
the occurrence and during the continuance of an Event of Default, each
Guarantor shall be deemed to be in default hereunder and Lender shall have the
rights and remedies of a secured party under the Uniform Commercial Code in
effect on the date hereof in the State of Illinois ("CODE") with respect to the
Collateral of such Guarantor, which rights and remedies shall be cumulative and
not exclusive to the extent permitted by law.  Without notice, demand or legal  
process of any kind, Lender, and its nominee, designee or agent, may take
possession of any or all of the Collateral of any or all of the Guarantors (in
addition to the Collateral of any Guarantor of which it already has
possession), wherever it may be found, and for that purpose may pursue the same
wherever it may be found, and may, without a breach of the peace, enter onto
any premises of any Guarantor (with respect to each 





                                 Page 4 of 15
<PAGE>   113
Guarantor, such Guarantor's "PREMISES") where any of the Collateral of such
Guarantor is or may be located, and search for, and take possession of, any or
all of such Collateral until the same shall be sold or otherwise disposed of in
accordance with the Code.  Lender, its nominee, designee or agent, shall have
the right to remove any or all of the Collateral of any Guarantor from the
Premises of any Guarantor and/or to assemble and store such Collateral on such
Premises, and otherwise to operate, occupy and use such Premises, in connection
with public or private sales of Collateral of any Guarantor, all without cost
to Lender, its nominee, designee or agent.  If an Event of Default exists, at
Lender's request, each Guarantor will, at such Guarantor's expense, assemble
the Collateral at one or more places reasonably convenient to both parties,
where the Collateral may remain at such Guarantor's expense, pending sale or
other disposition thereof.  Each Guarantor acknowledges that any breach by such
Guarantor of any of the provisions of this paragraph will cause irreparable
injury to Lender and that there is no adequate remedy at law for a breach of
the provisions of this paragraph.  Each Guarantor agrees that Lender will have
the immediate right, upon such breach, to obtain injunctive and other equitable
relief in any court of competent jurisdiction without any requirement of
notice, and that the granting of any such relief shall not preclude Lender from
pursuing any other available relief or remedies for such breach.

         At any time after maturity of the Liabilities, by acceleration or
otherwise, Lender may without notice to any Guarantor and regardless of the
acceptance of any collateral security for the payment hereof, appropriate and
apply toward the payment of the Liabilities (I) any indebtedness due or to
become due from Lender to such Guarantor, and (II) any moneys, credits or other
property belonging to such Guarantor, at any time held by or coming into the
possession of Lender.

         Any notification required by law of intended sale, lease or other
disposition by or on behalf of Lender of any of the Collateral of any Guarantor
shall be deemed reasonably and properly given if mailed, postage prepaid, to
such Guarantor at such Guarantor's address set forth below such Guarantor's
signature hereon at least five (5) days before such sale, lease or other        
disposition.  Any proceeds of any sale, lease or other disposition by or on
behalf of Lender of any of the Collateral of any Guarantor may be applied by
Lender to the payment of expenses in connection with the acquisition,
possession, protection, custody, preparation for sale, lease or disposition and
sole, lease or disposition of such Collateral, including, without limitation,
reasonable attorneys' and paralegals' fees and expenses.  Any balance of such
proceeds shall be applied by Lender toward the payment of the Liabilities. 
Each Guarantor shall remain liable for any deficiency, and Lender shall account
for any surplus.

<PAGE>   114
         IN AN EVENT OF DEFAULT EXISTS AS AFORESAID, EACH GUARANTOR (PURSUANT
TO AUTHORITY GRANTED BY ITS BOARD OF DIRECTORS) HEREBY WAIVES ALL RIGHTS TO
NOTICE AND HEARING OF ANY KIND PRIOR TO THE EXERCISE BY LENDER OF ITS RIGHTS TO
REPOSSESS THE COLLATERAL OF SUCH GUARANTOR WITHOUT JUDICIAL PROCESS OR TO
REPLEVY, ATTACH OR LEVY UPON SUCH COLLATERAL WITHOUT PRIOR NOTICE OR HEARING.
EACH GUARANTOR ACKNOWLEDGES THAT IT HAS BEEN ADVISED BY COUNSEL OF ITS CHOICE
WITH RESPECT TO THIS TRANSACTION AND THIS AGREEMENT.

         SECTION 7.  AMENDMENTS, EXTENSIONS, MODIFICATIONS, PARTIAL PAYMENTS,
RELEASES, ETC.; FINANCIAL CONDITION OF BORROWER.  Lender is hereby authorized,
without notice or demand and without affecting the liability of any Guarantor
hereunder, to, from time to time, (I) renew, extend, accelerate or otherwise
change the time for payment of, or other terms relating to, the Liabilities, or
otherwise modify, amend or change the terms of any promissory note or other
agreement, document or instrument now or hereafter executed by Borrower or any
other Person and delivered to Lender; (II) accept partial payments on the
Liabilities; (III) take and hold collateral security for the payment of the
Liabilities guaranteed hereby, or for the payment of this Guaranty, or for the
payment of any other guaranties of the Liabilities or other liabilities of
Borrower, and exchange, enforce, waive and release any such collateral
security; (IV) apply such collateral security and direct the order or manner of
sale thereof as in its discretion it may determine; and (V) settle, release,
compromise, collect or otherwise liquidate any or all of the Liabilities, any
other guarantor of the Liabilities, including any Guarantor, and any collateral
security therefor in any manner, in each case without affecting or impairing
the obligations of any Guarantor hereunder.

         Each Guarantor hereby assumes responsibility for keeping itself
informed of the financial condition of Borrower, and any and all endorsers
and/or other guarantors of any instrument or document evidencing all or any
part of the Liabilities, including any other Guarantor, and of all other
circumstances bearing upon the risk of nonpayment of the Liabilities or any
part thereof that diligent inquiry would reveal, and each Guarantor hereby
agrees that Lender shall not have any duty to advise such Guarantor of
information known to Lender regarding such condition or any such circumstances.
In the event Lender, in its sole discretion, undertakes at any time or from
time to time to provide any such information to any Guarantor, Lender shall be
under no obligation (I) to undertake any investigation not a part of its regular
business routine, (II) to disclose any information which, pursuant to accepted
or reasonable business practices, Lender wishes to maintain confidential, or
(III) to make any other or future disclosures of such information or any other
information to such Guarantor.

<PAGE>   115
         SECTION 8.  NO OBLIGATION TO MARSHALL ASSETS; REVERSAL OF PAYMENTS.
Each Guarantor consents and agrees that Lender shall be under no obligation to
marshall any assets in favor of such Guarantor or against or in payment of any
or all of the Liabilities.  Each Guarantor further agrees that, to the extent
that Borrower make a payment or payments to Lender, or Lender receives any
proceeds of the Collateral, which payment or payments or any part thereof are
subsequently invalidated, declared to be fraudulent or preferential, set aside
and/or required to be repaid to Borrower, its estate, trustee, receiver or any
other Person, including, without limitation, any Guarantor, under any
bankruptcy law, state or federal law, common law or equitable cause, then to
the extent of such payment or repayment, the Liabilities or part thereof which
has been paid, reduced or satisfied by such amount shall be reinstated and
continued in full force and effect as if such initial payment, reduction or
satisfaction had not occurred.

         SECTION 9.  SUBROGATION, REIMBURSEMENT, CONTRIBUTION AND INDEMNITY;
SUBORDINATION.  Each Guarantor hereby waives all rights of subrogation (whether
contractual, under Section 509 of the Bankruptcy Code, or otherwise) to the
claims of Lender against Borrower and all contractual, statutory or common law
rights of reimbursement, contribution or indemnity which may arise in
connection with this Guaranty.  Each Guarantor further agrees that any and all
claims of such Guarantor against Borrower, any endorser or any other guarantor
of all or any part of the Liabilities, or against any of their respective
properties shall be subordinate and subject in right of payment to the prior
indefeasible payment and satisfaction in full of all Liabilities.

         SECTION 10.  WAIVER BY LENDER.  No delay on the part of Lender in the
exercise of any right or remedy shall operate as a waiver thereof, and no
single or partial exercise by Lender of any right or remedy shall preclude any
further exercise thereof; nor shall any modification or waiver of any of the
provisions of this Guaranty be binding upon Lender, except as expressly set
forth in a writing duly signed and delivered on Lender's behalf by an   
authorized officer or agent of Lender.  The failure of Lender at any time or
times hereafter to require strict performance by Borrower, any Guarantor or any
other guarantor of the Liabilities of any of the provisions, warranties, terms
and conditions contained in the Debt Agreement or any promissory note, security
agreement, agreement, guaranty, instrument or document now or at any time or
times hereafter executed by Borrower, any Guarantor or any other guarantor of
the Liabilities and delivered to Lender shall not waive, affect or diminish any
right of Lender at any time or times thereafter to demand strict performance
thereof and such right shall not be deemed to have been waived by any act or
knowledge of Lender, its agents, officers or employees, unless such waiver is
contained in an instrument in writing signed by an officer or agent of Lender
and directed to each Guarantor specifying such waiver.  No waiver by Lender of
any default shall operate as a waiver of any other default or the same default
on a future occasion, 





                                 Page 7 of 15
<PAGE>   116
and no action by Lender permitted hereunder shall in any way affect or
impair Lender's rights or the obligations of any Guarantor under this Guaranty. 
Any determination by a court of competent jurisdiction of the amount of any
principal and/or interest owing by Borrower to Lender shall be conclusive and
binding on each Guarantor irrespective of whether such Guarantor was a party to
the suit or action in which such determination was made.

         SECTION 11.  CONTINUING GUARANTY.  Each Guarantor agrees that this
Guaranty shall continue in full force and effect and may not be terminated or
otherwise revoked until all Liabilities shall have been indefeasibly paid and
satisfied in full and the financing arrangements between Borrower and Lender,
whether evidenced by the Debt Agreement, promissory notes, or any other
instrument or document executed by Borrower and delivered to Lender pursuant to
the terms of the Debt Agreement, have been terminated pursuant to the
respective terms and provisions thereof.  In the event that any Guarantor shall
have any right under applicable law to otherwise terminate or revoke this
Guaranty, which right cannot be waived, each Guarantor agrees that such
termination or revocation shall not be effective until a written notice of such
revocation or termination, specifically referring hereto, signed by each
Guarantor, is actually received by Lender.  Such notice shall not affect the
right and power of Lender to enforce rights arising prior to receipt thereof.
If, in reliance on this Guaranty, Lender grants loans or takes other action
after the termination or revocation by any Guarantor but prior to the receipt
by Lender of said written notice, the rights of Lender with respect thereto
shall be the same as if such termination or revocation had not occurred.

         SECTION 12.  SUCCESSORS AND ASSIGNS.  This Guaranty shall be binding
upon each Guarantor and upon the respective successors and assigns of such
Guarantor and shall inure to the benefit of Lender's respective successors and
assigns; all references herein to Borrower and to any Guarantor shall be deemed
to include their respective successors and assigns.  The respective successors
and assigns of Borrower and of each Guarantor shall include, without
limitation, a receiver, trustee or debtor-in-possession of or for such Person.
All references to the singular shall be deemed to include the plural where the
context so requires and vice-a-versa.

         SECTION 13.  AUTHORIZATION FOR OFFICERS TO ACT.  Each Guarantor hereby
certifies that it has all necessary power and authority to grant and execute
this Guaranty and to perform its respective obligations hereunder.  Each
Guarantor authorizes its Chairman, President and each of its Vice Presidents,
severally and not jointly, on behalf and in the name of such Guarantor from
time to time in the discretion of such officer, to take or omit to take any and
all actions and to execute and deliver any and all documents and instruments
which such officer may determine to be necessary or desirable in relation to,
and perform any obligations arising in connection with, this Guaranty and any




                                 Page 8 of 15
<PAGE>   117
of the transactions contemplated hereby, and, without limiting the generality
of the foregoing, hereby gives to each such officer severally the power and
right on behalf of such Guarantor, without notice to or assent by such
Guarantor, to do the following:  (I) to execute and deliver any amendment,
waiver, consent, supplement, other modification, or reaffirmation of this
Guaranty or any document covering any of the collateral security for this
Guaranty, and to perform any obligation arising in connection herewith or
therewith; (II) to sell, transfer, assign, encumber or otherwise deal in or
with the security for this Guaranty or any part hereof; (III) to grant liens,
security interests or other encumbrances on or in respect of any property or
assets of such Guarantor, whether now owned or hereafter acquired, in favor of
Lender; (IV) to send notices, directions, orders and other communications to
any Person relating to this Guaranty, any collateral security for this Guaranty
or to any document covering any security for this Guaranty; (V) to take or omit
to take any other action contemplated by or referred to in this Guaranty or any
document covering any of the collateral security for this Guaranty; and (VI) to
take or omit to take any other action with respect to this Guaranty, any of the
collateral security for this Guaranty or any document covering any of the
collateral security for this Guaranty, all as such officer may determine in
his/her sole discretion.

         SECTION 14.  GOVERNING LAW; CONSENT TO JURISDICTION; SERVICE OF
PROCESS.  THIS AGREEMENT AND THE CONVERTIBLE SECURED NOTES SHALL BE GOVERNED
BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF ILLINOIS,
WITHOUT REGARD TO ITS PRINCIPLES OF CONFLICTS OF LAW.  BORROWER HEREBY

OF ANY SUCH ACTION OR PROCEEDING.  BORROWER AGREES THAT A FINAL JUDGMENT IN ANY
SUCH ACTION OR PROCEEDING SHALL BE CONCLUSIVE AND MAY BE ENFORCED IN

RESPECT.  A COPY OF ANY SUCH PROCESS SO SERVED SHALL BE MAILED BY REGISTERED
MAIL TO EACH GUARANTOR AT ITS ADDRESS SET FORTH BELOW ITS SIGNATURE HEREON,
EXCEPT THAT UNLESS OTHERWISE PROVIDED BY APPLICABLE LAW, ANY FAILURE TO MAIL

         Reference is made to a Series A 11.75% Cumulative Convertible
Preferred Stock Purchase Agreement dated April 22, 1996 (the "Agreement").

         The undersigned are parties to the Agreement and wish to set forth
certain additional agreements that they have reached in connection with the
transactions contemplated by the Agreement.

         1.      The Agreement, as prepared, contemplated that it would be
entered into by Seymour Kessler ("Kessler") on behalf of Romajo Partners
Limited Partnership ("Romajo").  It is acknowledged by the undersigned parties
that Kessler, who was present at the closing of the above agreements and was
represented and accompanied by counsel, refused to enter into the Agreement or
to proceed with the transactions contemplated thereby.  The parties further
acknowledge that Laport (as defined in the Agreement) exercised his option
under Section 2.6 of the Agreement to be the sole Purchaser thereunder having
the rights and obligations of Romajo.  Laport hereby assigns his rights
thereunder to Amsterdam Equities Limited ("Amsterdam").  The parties agree, as
promptly as possible after the date hereof, to enter into revised documents to
reflect the foregoing and to eliminate the name of Romajo from the Agreement
and from any related agreements and documents, and to substitute therefor the
name of Amsterdam.

         2.      Laport hereby agrees to provide a summary break-down of all
expenses included in Section 3.1.5 of the Agreement to Princeton within thirty
(30) days following the date hereof. Laport further agrees to use reasonable
efforts to obtain a summary break-down of the expenses of Amsterdam set forth
in Section 4.1.5 of the Convertible Debt Agreement.

VIA TELECOPY

Dr. Charles R. Mitchell
President
Princeton Dental Management Corporation
2358 Hassell Road
Hoffman Estates, IL 60195

Re: PRINCETON DENTAL MANAGEMENT CORPORATION ("PDMC")

Dear Dr. Mitchell:

         The following represents an agreement by and among PDMC, Dr. Charles
R. Mitchell ("Mitchell"), Stratum Management, Inc. ("Stratum"), John H. Hagan
("Hagan"), Dr. Seymour Kessler ("Kessler"), Amsterdam Equities Limited
("Amsterdam"), Frank Leonard Laport ("Laport"), and Beverly Trust Company, as
Custodian of the Frank Leonard Laport Rollover Individual Retirement Account
Number 75-49990 ("Laport IRA").

         1. Series B Activation. Effective immediately, the PDMC Series B
Preferred Stock for which Amsterdam currently holds a Warrant to Purchase (the
"Series B Stock"), will be issued to Amsterdam and activated. PDMC will
immediately execute any documentation, including without limitation, amending
the Certificate of Designation of the Series B Stock filed with the Secretary
of State of Delaware, to ensure that the holder of the Series B Stock has the
immediate and unconditional right (subject only to the provisions of Item 8
hereof) to appoint the Series B Director called for by the Series B Certificate
of Designation.

         2. Orderly Transition. All parties agree to use their best efforts to
ensure that the transition in current management and the move of the PDMC
headquarters to another Chicagoland location will be as orderly as possible.
Towards this end, Hagan and Kessler would agree to stay on as PDMC Directors
until the next PDMC shareholder's meeting, which is scheduled to take place on
September 13, 1996. Mitchell would resign as President of PDMC, but would agree
to stay on as a PDMC Director and as an independent consultant until the next
PDMC shareholder's meeting, which is scheduled to take place on September 13,
1996. At PDMC's sole option, during such time period Mitchell would either (i)
continue to work full time for PDMC at his current compensation level, or (ii)
work part time for PDMC as PDMC shall deem necessary, in which case Mitchell's
compensation as a consultant would be reduced proportionately.

         3. Certification. Mitchell would, to the best of his knowledge based
upon investigation in his capacity as an officer and director of PDMC, certify
that the PDMC financial statements for the quarter ended June 30, 1996 were
true and accurate. In this regard, I would note that, as of yesterday,
Amsterdam had not yet received these financial statements.

         4. Option/Warrant Forfeiture. Stratum, Hagan and Kessler would
forfeit, on a pro-rata basis, an aggregate amount of 300,000 options/warrants
for PDMC stock, to PDMC, to be cancelled by PDMC or reallocated to the PDMC
employee stock option plan; provided, however, that if Kessler refuses to
execute this letter agreement, the aggregate number of options/warrants to be
forfeited by Stratum and Hagan shall be 200,000. Stratum, Hagan, Mitchell and
Kessler would agree to immediately execute any documentation which might be
required to effectuate the forfeiture of such options/warrants.

         5. Kessler Debt. Kessler shall agree that he will not call or demand
payment on any debt which may be due him or any affiliated entity by PDMC until
after the next PDMC shareholder's meeting. Kessler shall execute any required
documentation in this regard.

         6. Additional Funding. Contingent upon the actions contemplated in
Items 1 through 5 being completed, Amsterdam would agree to advance PDMC an
additional U.S.$200,000.00 pursuant to the convertible debt agreement, to be
used by PDMC solely for the payment of specifically designated PDMC accounts
payable which are critical to the continued and uninterrupted operation of
PDMC's dental practices and laboratory operations. Any such payments shall
require the prior, specific written authorization of Amsterdam or its
designated representative.

         7. Conversion. Contingent upon the actions contemplated in Items 1
through 5 being completed, Amsterdam, Laport and the Laport IRA would agree to
convert, on a pro-rata basis, an aggregate amount of U.S.$700,000.00 of
currently outstanding convertible debt/preferred stock into PDMC common stock
in accordance with the contractual terms of the convertible debt/preferred
stock.

         8. Timing. As we have repeatedly advised, time is absolutely of the
essence if this matter is to be resolved.  Accordingly, all of the actions
contemplated in Items 1 through 5 must take place as soon as possible and in no
event later than July 15, 1996.  Upon the timely completion of all of the
actions contemplated in Items 1 through 5, the actions contemplated in Items 6
and 7 would be completed no later than fourteen (14) business days

following such timely completion. If Amsterdam, Laport and Laport IRA fail to
take any action which is within their sole and exclusive control and is
reasonably required to be taken by them in order to effectuate the actions
contemplated in Items 6 and 7 within the above-referenced fourteen (14)
business days, and PDMC provides written notice of such failure to Amsterdam,
Laport and Laport IRA, Amsterdam agrees that it shall not exercise its right to
appoint a Series B Director until such actions have been taken, and if any such
actions are not taken by July 31, 1996, this letter of agreement shall be null
and void upon written notice by PDMC to Amsterdam on or before August 5, 1996.

         9. Litigation. There is no pending or, to the best knowledge of the
undersigned, threatened litigation against PDMC except as set forth on Exhibit
A attached hereto and incorporated herein.

         If this letter, which is intended to be a binding and enforceable
agreement among the parties signing hereto, reflects your understanding of the
agreement among the parties, please sign where indicated, and arrange to have
this agreement signed by Stratum, Hagan, and Kessler. Upon execution, please
return 5 original copies to my attention no later than the close of business on
July 15, 1996, and I will arrange for this agreement to be signed by Amsterdam,
Laport and the Laport IRA.

         This letter of agreement may be signed in counterparts. It is further
agreed that, irrespective of whether Kessler executes this letter agreement in
any capacity, this letter agreement shall be entirely binding upon the other
signing parties hereto.

                                   Sincerely,
