standing instruction, which it shall confirm upon request from time to time,
that all payments due to P.C. shall be remitted directly to Service Company as
its agent and attorney-in-fact hereunder.  To the extent that the foregoing

                            Services and such other payments or disbursements
                            as P.C. shall direct Service Company to make in

                     (ii)   Second, Service Company shall retain out of Net

amounts due under Section 5(b) by the end of the following month.  The Service
Fee shall be reviewed annually and at such other times as may be deemed
appropriate and adjusted in such manner as the parties may agree; in the
absence of such agreement, the Service Fee then in effect shall continue in
effect.

       6.     General Obligations of P.C. and Service Company.  P.C. and
Service Company each agrees to cooperate fully with the other in connection
with the carrying out of their respective obligations under this Agreement and
to employ their best efforts to resolve any dispute which may arise under or in
connection with the carrying out of this Agreement.

       7.     Term.  The term of this Agreement shall be for a period of 40

"Subleases") to P.C., for the purpose of conducting and operating a Dental
Center, the "Demised Premises," as described in each of the Leases listed on

              (c)    P.C. shall pay to Service Company as rent an amount equal
to the rent being paid by Service Company to landlord under the Leases.

              (d)    P.C. covenants that it will be bound by and will perform
and comply with all the obligations of tenant under the Leases, all of which
are incorporated herein by reference, and agrees that whenever appropriate, the
term "tenant" shall be deemed to refer to P.C. to the same extent as if P.C.
were a party to the Leases; provided, however, that P.C. shall have no rights
against landlord under the Leases and shall have only such rights against
Service Company as are set forth in this Agreement.

              (e)    Without limiting the foregoing provisions, P.C. shall not
have any right or obligation to enter into agreements directly with landlord;

term of any of the Subleases; and shall not have any right to sublet, without
the consent of Service Company, any of the Demised Premises under any Lease.

will, upon the request of Service Company, promptly execute such amendment of
Sublease as is necessary to conform the Sublease to the amended Leases.

              (f)    The rights of P.C. under the Subleases shall remain at all
times subject to the rights of Service Company under the Leases and in the
event any of the Leases is terminated for any reason, the respective Sublease

obligation to P.C. as a result of such termination.

       9.     Termination.  This Agreement may be terminated as follows:

              (b)    If either party fails to perform any of its obligations
under this Agreement and, after written notice from the other party demanding
that such failure be cured, the party on whom such notice is served shall fail
to cure such breach within 30 days after such notice or, if such breach will
reasonably require more than 30 days to cure, such party is not diligently
pursuing efforts to cure such breach; provided, however, that if the party on
whom such demand is made elects to submit such dispute to arbitration, no
action to terminate this Agreement can be taken until such arbitration has been
finally adjudicated and then only if the party guilty of such failure shall
fail to comply with the arbitration award within 60 days after its issuance.

              (c)    If any bankruptcy, insolvency or receivership proceedings
are instituted by or against the P.C. and not dismissed within sixty (60) days

equipment and furnishings provided by Service Company at the Dental Centers for
a purchase price equal to the appraised fair market value thereof.

       10.    Relationship of Parties. This Agreement is not intended to and
shall not be construed as creating the relationship of employer and employee,
partnership, joint venture or association between Service Company and P.C.
Since the dentists who perform services for the P.C. are not employees or
independent contractors of Service Company, Service Company shall not withhold
on their behalf any amounts for income tax, social security, unemployment
compensation, workers compensation or other similar withholding provisions and
all such withholding shall be the obligation of P.C.

       11.    Confidential Information.  Each of P.C. and Service Company
acknowledges that it will have access to information of proprietary nature
owned by the other including (i) information on the systems, policies and
procedures developed by Service Company in connection with the providing of
management services for dental centers and dental practices and (ii) patient
information.  P.C. acknowledges that Service Company has a proprietary interest
in such information, that such information constitutes trade secrets and that
P.C. does not, by reason of this Agreement, acquire any continuing right or
interest in such proprietary information or trade secrets.  P.C. will hold such
proprietary information and trade secrets in confidence and will not disclose
them, either during the term of this Agreement or thereafter, to any person or
entity other than employees or independent contractors of P.C. or Service
Company without the prior written consent of Service Company or as may be
required by law.  Service Company will preserve the confidentiality of all
files and records of P.C. including patient records and comply with all
federal, state and local laws, rules and regulations relating to the
confidentiality of P.C.'s files and records (including patient records).
Service Company will use the information in such records only for the limited
purposes necessary to perform the services of Service Company set forth herein
(including billing and collections) and shall not use patient names, addresses
or any other patient information for marketing or any other purpose except as
expressly permitted by this Agreement without the prior written consent of P.C.
Each of P.C. and Service Company acknowledges that it does not have an adequate
remedy at law for a breach of this Section 11, will suffer irreparable harm in
the event of such breach and that, therefore, the other party shall be entitled
to injunctive and other equitable relief for the enforcement of this Section
11. The provisions of this Section 11 shall survive termination of this
Agreement.

       12.    Miscellaneous.

              (a)    Assignment.  This Agreement shall not be assignable by
either party hereto without the express prior written consent of the other;
provided, however, that this Agreement shall be assignable by Service Company
to any of its affiliates or successors without the consent of P.C.

              (b)    Waiver.  Waiver of any agreement or obligation set forth
in this Agreement by either party shall not prevent that party from later
insisting upon full  performance of such agreement or obligation and no course
of dealing, partial exercise or any delay or failure on the part of any party
hereto in exercising any right, power, privilege, or remedy under this
Agreement or any related agreement or instrument shall impair or restrict any
such right, power, privilege or remedy or be construed as a waiver therefor.
