EXHIBIT 10.4

EMPLOYMENT AGREEMENT

This Employment Agreement ("Agreement") is made effective as of November 3,
1997 (the "Effective Date") by and between GENTLE DENTAL SERVICE CORPORATION, a
Washington corporation (the "Company"), and DANY Y. TSE, DMD ("Employee").

RECITALS

Pursuant to the Agreement and Plan of Merger dated October 30, 1997 (the
"Merger Agreement") between the Company and GMS Dental Group, Inc., a Delaware
corporation, the Company has agreed to employ Employee as its Co-Chairman,
Founder and President of Clinical Services Council. Employee wishes to accept
such position of employment with the Company.

AGREEMENT

In consideration of the promises, covenants, and representations below, the
parties agree as follows:

1. Compensation. From the Effective Date until December 31, 1997, the
------------
Company will pay Employee as compensation for Employee's services a base salary
("Base Salary") at an annual rate of $230,000. During 1998, the Company will
pay Employee a Base Salary no less than the greater of (i) 90% of the base
salary of the President and Chief Executive Officer of the Company or (ii)
$243,000, and with respect to bonus, stock options and all other items
considered as compensation for SEC disclosure purposes, the Company will provide
Employee 90% of the compensation paid to the President and Chief Executive
Officer. During the remaining term of employment, Base Salary and other
compensation shall be determined by the compensation committee of the Board of
Directors of the Company (the "Compensation Committee"). Employee's Base Salary
will be payable in accordance with the Company's standard payroll procedures.

2. Duties. Employee shall serve as Co-Chairman, Founder and President of
------
Clinical Services Council of the Company and shall perform such appropriate and
reasonable duties as may be delegated to Employee by the Board of Directors (the
"Board") or Chief Executive Officer of the Company. Employee shall be employed
on a full-time basis and shall devote all of Employee's working time, attention
and energies to the Company during the term of Employee's employment. Employee
shall be provided reasonable resources with which to perform his duties,
including but not limited to the support of a secretary and a national dental
officer. Notwithstanding the preceding, Employee will not be precluded from
engaging in appropriate professional, educational, civic, charitable or
religious activities or from devoting a reasonable amount of time to private
investments that do not interfere or conflict with
<PAGE>

Employee's responsibilities to the Company. Employee shall principally perform
Employee's duties hereunder at the executive offices of the Company located in
Vancouver, Washington.

3. Term of Employment. Employee's employment with the Company is for an
------------------
initial term (the "Initial Term") commencing on the date of this Agreement and
ending in approximately 4 1/2 years on April 30, 2002. During the Initial Term,
the Company may not terminate Employee's employment other than for "cause" (as
defined in Section 8(b) below). After the completion of the Initial Term,
Employee's employment with the Company will be "at-will" and, therefore, the
Company will thereafter be able to terminate Employee's employment at any time
for any reason, with or without cause.

4. Employee Benefits. During the term of Employee's employment, Employee
-----------------
will be eligible to participate in the employee benefit plans and executive
compensation programs (including any bonus plan(s) established by the
Compensation Committee) maintained from time to time for other senior executive
officers of the Company to the extent that other senior executive officers of
similar level and duties are eligible to participate in such programs and if
Employee qualifies for participation in any such programs. These benefits may
change from time to time.

5. Business Expenses. During the term of Employee's employment, the
-----------------
Company shall reimburse Employee for necessary and reasonable travel,
entertainment and other business expenses appropriately incurred by Employee in
connection with performing Employee's duties. The Company will reimburse
Employee for such expenses upon presentation of an itemized account and
appropriate supporting documentation, all in accordance with the Company's
generally applicable policies.

6. Proprietary Information Agreement. Employee will sign and abide by
---------------------------------
the terms of the Proprietary Information Agreement, the form of which is
attached as Exhibit A.
---------

7. Vacation and Holidays. Employee will be entitled to fully-paid
---------------------
vacation time and holidays consistent with the Company's policy as may be in
place from time to time.

8. Severance Compensation.
----------------------

(1) In the event that Employee's employment with the Company is terminated
by Employee for "good reason" (as defined below) during the initial three years
after the Effective Date hereof, and provided that Employee complies with the
provisions of Section 9 hereof, Employee will enter into a twelve-month
consulting agreement at Employee's Base Salary as of the date of the termination
of Employee's employment (the "Termination Date"). Following the termination of
such consulting agreement, Employee will receive severance payments from the
Company for 24 months at Employee's Base Salary as of the Termination Date,
payable in equal monthly installments. If Employee's employment is terminated
by Employee for "good reason" subsequent to the initial three years of
employment

2
<PAGE>

after the Effective Date hereof or if, after the expiration of the Initial Term,
Employee's employment is terminated by the Company for any reason other than
"cause" (as defined below), and provided in either case that Employee complies
with the provisions of Section 9 hereof, Employee will enter into a twelve-month
consulting agreement at Employee's Base Salary as of the Termination Date.
Following the termination of such consulting agreement, Employee will receive
severance payments from the Company for twelve months at Employee's Base Salary
as of the Termination Date, payable in equal monthly installments.

(2) For purposes of this Agreement, "cause" shall mean (i) Employee's
continuous and willful inattention to Employee's duties after at least one
written notice of same has been given to Employee and Employee has been given an
opportunity to cure the same within thirty days after such notice; (ii) any
breach by Employee of Section 9 of this Agreement; (iii) any act committed by
Employee with respect to the property or the business of the Company which
constitutes gross recklessness, willful or gross misconduct or fraud; or (iv)
criminal conduct which has caused material injury to the Company and which could
reasonably result in conviction of a felony which involves fraud, dishonesty or
moral turpitude, excluding from the definition of "cause," without limitation,
such events as are stated not to constitute "cause" in the following sentence.
Employee shall not be considered to have been terminated for "cause" if
terminated by the Company solely (a) as a result of Employee's bad judgment or
negligence, (b) because of any act or omission believed by Employee in good
faith to have been in or not opposed to the best interests of the Company
(without intent of gaining therefrom directly or indirectly a profit to which
Employee was not legally entitled) and reasonably believed by Employee not to
have been improper or unlawful, (c) because of an act or omission in respect of
which a determination could properly have been made by the Board that Employee
met the applicable standard of conduct prescribed for indemnification or
reimbursement under the bylaws or charter of the Company, or the laws of the
State of Washington, in each case in effect at the time of such acts or
omissions, or (d) because of any act or omission with respect to which notice of
termination is given more than twelve months after the earliest date on which a
non-employee director of the Company who is not a party to such act or omission
knew or should have known of such act or omission.

(3) For purposes of this Agreement, "good reason" shall mean termination of
Employee's employment by Employee within thirty days following (x) any
relocation of the Company's executive offices where Employee is employed on the
Effective Date to a new location which is in excess of 25 miles from its current
location, (y) a demotion in position from Co-Chairman and President of Clinical
Services Council of the Company, or (z) the assignment of duties and
responsibilities of materially lesser status, dignity and character, or a
substantial reduction in the nature or status of Employee's duties and
responsibilities.

<PAGE>

medical, life insurance, disability insurance and any other similar benefits to
the same extent as theretofore provided by the Company to Employee prior to the
Termination Date.

9. Restrictive Covenants and Confidentiality.
-----------------------------------------

(1) Non-Solicitation. Employee agrees that during the term of Employee's
----------------
employment and for a period of one year following any termination thereof (for
any reason), Employee shall not (either directly or indirectly) solicit, entice,
encourage or induce any person who at any time within one year prior to
Employee's termination of employment shall have been an employee of the Company
or any of its subsidiaries, or who is a dentist who is employed by or performing
professional services for any dental practice managed by the Company or one of
its subsidiaries, to become employed by or associated with any person, firm or
corporation other than the Company, and Employee shall not approach any such
employee or dentist for such purpose or encourage the taking of such actions by
any other person, firm or corporation or assist any such person, firm or
corporation in taking such action.

(2) Non-Compete. Employee agrees that during the term of Employee's
-----------
employment and during any period in which Employee is receiving severance
compensation pursuant to Section 8 hereof, Employee shall not, directly or
indirectly, within a 50 mile radius of any location where the Company or any of
its subsidiaries owns, manages, develops, or operates any dental practice or
assets, engage or participate or make any financial investments in, or become
employed by, or act as an agent or principal of, or render advisory or other
services to or for, any person, firm or corporation that is engaged, directly or
indirectly, in any line of business then engaged in, or planned to be engaged
in, by the Company (a "Competing Enterprise"). A Competing Enterprise shall not
include any practice of dentistry with or consulting to a group of 10 or fewer
dentists located outside of a five mile radius of any location where the Company
or any of its subsidiaries owns, manages, develops or operates any dental
practice or assets. Similarly, nothing herein contained shall restrict Employee
from engaging in the solo practice of dentistry outside of a five mile radius of
any location where the Company or any of its subsidiaries owns, manages,
develops or operates any dental practice or assets. Nothing herein contained
shall restrict Employee from holding investments in not more than three percent
of the voting securities of any Competing Enterprise whose stock is listed on a
national securities exchange or is actively traded on the National Association
of Securities Dealers Automated Quotation System, so long as in connection with
such investments Employee does not render services to a Competing Enterprise.

10. Survival. The provisions of this Agreement shall survive the
--------
termination of Employee's employment with the Company, irrespective of the
reason therefor.

11. Remedies. Employee acknowledges that the services to be rendered by
--------
Employee are of a special, unique and extraordinary character and, in connection
with such

4
<PAGE>

services, Employee will have access to confidential information vital to the
Company's and its subsidiaries' businesses. By reason of this access, Employee
consents and agrees that if Employee violates any of the provisions of this
Agreement, the Company and its subsidiaries shall be entitled, without the need
to show actual damages, to an injunction and a temporary restraining order from
any court of competent jurisdiction restraining Employee from committing or
continuing any such violation of this Agreement. Employee acknowledges that
damages at law would not be an adequate remedy for violation of this Agreement,
and Employee therefore agrees that the provisions of this Agreement may be
specifically enforced against Employee in any court of competent jurisdiction.
The rights, powers and remedies of the Company under this Agreement are
cumulative and not exclusive of any other right, power or remedy which the
Company may have under any other agreement or by law.

12. Miscellaneous.
-------------

(1) Successors and Assigns. This Agreement shall be binding on and inure
----------------------
to the benefit of the parties hereto and their heirs, executors, legal
representatives, successors and assigns. Neither party shall have the right to
assign its obligations, or all or any portion of their rights or interests under
this Agreement without the prior written consent of the other party hereto, and
any attempt to do so will be null and void.

(2) Governing Law. This Agreement is made and entered into and is to be
-------------
governed by the internal laws of the State of California, applicable to

of 18 months following the effective date of such termination (the "Termination
Date"), payable in equal monthly installments. In the event, after the

this Agreement, the Company and its subsidiaries shall be entitled, without the
need to show actual damages, to an injunction and a temporary restraining order
from any court of competent jurisdiction restraining Employee from committing or

-----------------------------------------------------------

GMS Dental Group, Inc.
180 N. Riverview Drive, Suite 255
Anaheim Hills, CA 92808

Gentlemen:

I recognize that GMS Dental Group, Inc., a Delaware corporation (the
"Company"), is engaged in a continuous program of research, development and
production with respect to its business, present and future.

I understand that:

A. As part of my employment by the Company I am expected to make new
contributions and inventions of value to the Company.

B. I understand that my employment creates a relationship of confidence
and trust between me and the Company with respect to any information:

(1) applicable to the business of the Company; or

(2) applicable to the business of any client or customer of the
Company,

which may be made known to me by the Company or by any client or customer of the
Company, or learned by me during the period of my employment.

C. The Company possesses and will continue to possess information that
has been created, discovered or developed, or has otherwise become known to the
Company (including without limitation information created, discovered, developed
or made known by or to me during the period of or arising out of my employment
by the Company), and/or in which property rights have been assigned or otherwise
conveyed to the Company, which information has commercial value in the business
in which the Company is engaged. All of the aforementioned information is
hereinafter called "Confidential Information." By way of illustration, but not
limitation, Confidential Information includes all data, compilations,
specifications, strategies, projections, processes, techniques, formulae, models
and patent disclosures; and all tangible and intangible embodiments thereof of
any kind whatsoever including, where appropriate and without limitation, all
compositions, machinery, apparatus, records, reports, drawings, patent
applications and documents.

In consideration of my employment or continued employment, as the case may
be, and the compensation received by me from the Company from time to time,
subject to Section 12 hereof, I hereby agree as follows:

<PAGE>

1. All Confidential Information shall be the sole property of the Company
and its assigns, and the Company and its assigns shall be the sole owner of all
patents and other rights in connection therewith. I hereby assign to the Company
any rights I may have or acquire in all Confidential Information. At all times
during my employment by the Company and at all times after termination of such
employment, I will keep in confidence and trust all Confidential Information,
and I will not disclose, sell, use, lecture upon or publish any Confidential
Information or anything relating to it without the written consent of the
Company, except as may be necessary in the ordinary course of performing my
duties as an employee of the Company.

2. I agree that during the period of my employment by the Company, I will
not, without the Company's express written consent, engage in any employment or
activity in any business competitive with the Company.

3. All documents, data, records, apparatus, equipment, chemicals,
molecules, organisms and other physical property, whether or not pertaining to
Confidential Information, furnished to me by the Company or produced by myself
or others in connection with my employment shall be and remain the sole property
of the Company and shall be returned promptly to the Company as and when
requested by the Company. Should the Company not so request, I shall return and
deliver all such property upon termination of my employment by me or by the
Company for any reason and I will not take with me any such property or any
reproduction of such property upon such termination.

4. [INTENTIONALLY OMITTED]

5. I will promptly disclose to the Company, or any persons designated by
it, all improvements, inventions, formulae, processes, techniques, know-how and
data, whether or not patentable, made or conceived or reduced to practice or
learned by me, either alone or jointly with others, during the period of my
employment which are related to or useful in the business of the Company, or
result from tasks assigned me by the Company, or result from use of premises
owned, leased or contracted for the Company (all said improvements, inventions,
formulae, processes, techniques, know-how and data shall be collectively
hereinafter called ("Inventions")); such disclosure shall continue for one year
after termination of the Agreement with respect to anything that would be an
Invention if made, conceived, reduced to practice or learned during the term
hereof.

6. I agree that all Inventions shall be the sole property of the Company
and its assigns, and the Company and its assigns shall be the sole owner of all
patents and other rights in connection therewith. I hereby assign to the Company
any rights I may have or acquire in all Inventions. I further agree as to all
Inven-

-2-
<PAGE>

tions to assist the Company in every proper way (but at the Company's expense)
to obtain and from time to time enforce patents on the Inventions in any and all
countries, and to that end I will execute all documents for use in applying for
and obtaining such patents thereon and enforcing same, as the Company may
desire, together with any assignments thereof to the Company or persons
designated by it. My obligation to assist the Company in obtaining and enforcing
patents for the Inventions in any and all countries shall continue beyond the
termination of my employment, but the Company shall compensate me at a
reasonable rate after such termination for time actually spent by me at the
Company's request on such assistance. In the event that the Company is unable
for any reason whatsoever to secure my signature to any lawful and necessary
document required to apply for or execute any patent application with respect to
Inventions (indicating renewals, extension, continuations, divisions or
continuations in part thereof), I hereby irrevocably designate and appoint the
Company and its duly authorized officers and agents, as my agents and
attorneys-in-fact to act for and in my behalf and instead of me, to execute and
file any such application and to do all other lawfully permitted acts to further
the prosecution and issuance of patents thereon with the same legal force and
effect as if executed by me.

7. As a matter of record I have attached hereto a complete list of all
inventions or improvements relevant to the subject matter of my employment by
the Company which have been made or conceived or first reduced to practice by me
alone or jointly with others prior to my employment by the Company which I
desire to remove from the operation of the Agreement; and I covenant that such
list is complete. If no such list is attached to the Agreement, I represent that
I have made no such inventions and improvements at the time of signing the
Agreement.

8. I represent that my performance of all the terms of the Agreement and
that my employment by the Company does not and will not breach any agreement to
keep in confidence proprietary information acquired by me in confidence or in
trust prior to, and continuing throughout, my employment by the Company. I have
not entered into, and I agree I will not enter into, any agreement either
written or oral in conflict herewith.

9. I understand, as part of the consideration for the offer of employment
extended to me by the Company and of my employment or continued employment by
the Company, that I have not brought and will not bring with me to the Company
or use in the performance of my responsibilities at the Company any equipment,
supplies, facility or trade secret information of any former employer which are
not generally available to the public, unless I have obtained written
authorization for their possession and use.

10. I also understand that, in my employment with the Company, I am not to
breach any obligation of confidentiality that

-3-
<PAGE>

I have to others, and I agree that I shall fulfill all such obligations during
my employment with the Company.

11. I agree that in addition to any other rights and remedies available to
the Company for any breach by me of my obligations hereunder, the Company shall
be entitled to enforcement of my obligations hereunder by court injunction.

12. If any provision of the Agreement shall be declared invalid, illegal
or unenforceable, such provision shall be severed and all remaining provisions
shall continue in full force and effect.

13. The Agreement does not apply to inventions which qualify fully for
protection under Section 2870 of the California Labor Code, which are ideas or
inventions for which no equipment, supplies, facility or trade secret
information of the Company was used and which were developed entirely on my own
time, and (1) which do not relate at the time of conception or reduction to
practice of the invention (a) to the business of the Company, or (b) to the

(b) Exercise of Options on Termination of Service. Each Stock Option
---------------------------------------------
Agreement shall set forth the extent to which the Optionee shall have the right
to exercise the Option following termination of the Optionee's Service with the
Company and its Subsidiaries. Such provisions shall be determined in the sole
discretion of the Committee, need not be uniform among all Options issued
pursuant to the Plan, and may reflect distinctions based on the reasons for
termination of employment. Notwithstanding the foregoing, to the extent
required by applicable law, each Option shall provide that the Optionee shall
have the right to exercise the vested portion of any Option held at termination
for at least 30 days following termination of Service with the Company for any
reason, and that the Optionee shall have the right to exercise the Option for at
least six months if the Optionee's Service terminates due to death or
Disability.

--------------------------
Optionee, shall have no rights as a shareholder with respect to any Shares

limitations of the Plan, the Committee may modify, extend or assume outstanding
Options or may accept the cancellation of outstanding Options (whether granted
by the Company or another issuer) in return for the grant of new Options for the
same or a different number of Shares and at the same or a different Exercise
Price.

----------------------------------
Option may not be sold or otherwise transferred or disposed of by the Optionee
during such period as may be specified by the Company or its underwriter on or
following the effective date of a registration statement covering securities of
the Company filed under the Securities Act of 1933.

-8-
<PAGE>

Subject to the preceding sentence, any Shares issued upon exercise of an
Option shall be subject to such rights of repurchase, rights of first refusal
and other transfer restrictions as the Committee may determine. Such
restrictions shall be set forth in the applicable Stock Option Agreement and
shall apply in addition to any restrictions that may apply to holders of Shares
generally.

------------
Plan shall be payable in lawful money of the United States of America at the

specified by the Committee and which are surrendered to the Company in good form
for transfer. Such Shares shall be valued at their Fair Market Value on the date
when the new Shares are purchased under the Plan.

note executed by the Optionee. The interest rate and other terms and conditions
of such note shall be determined by the Committee. The Committee may require
that the Optionee pledge his or her Shares to the Company for the purpose of
securing the payment of such note. In no event shall the stock certificate(s)
representing such Shares be released to the Optionee until such note is paid in
full.

(d) Cashless Exercise. To the extent that a Stock Option Agreement so
-----------------
provides and a public market for the Shares exists, payment may be made all or
in part by delivery (on a form prescribed by the Committee) of an irrevocable
direction to a securities broker to sell Shares and

-9-
<PAGE>

to deliver all or part of the sale proceeds to the Company in payment of the
aggregate Exercise Price.

SECTION 8. ADJUSTMENT OF SHARES.
- -------------------------------

(a) General. In the event of a subdivision of the outstanding Stock, a

in a form other than Shares in an amount that has a material effect on the value
of Shares, a combination or consolidation of the outstanding Stock into a lesser

other increase or decrease in the number of shares of stock of any class. Any
issue by the Company of shares of stock of any class, or securities convertible
into shares of stock of any class, shall not affect, and no adjustment by reason
thereof shall be made with respect to, the number or Exercise Price of Shares
subject to an Option. The grant of an Option pursuant to the Plan shall not
affect in any way the right or power of the Company to make adjustments,
reclassifications, reorganizations or changes of its

-10-
<PAGE>

capital or business structure, to merge or consolidate or to dissovle,
liquidate, sell or transfer all or any part of its business or assets.

SECURITY AGREEMENT

THIS AGREEMENT, entered into as of April 1, 1997, between GMS DENTAL GROUP,
INC., a Delaware corporation (the "Company"), and MICHAEL T. FIORE
("Purchaser").

W I T N E S S E T H:

WHEREAS, Purchaser has purchased from the Company 750,000 shares of the
Company's Common Stock (the "Shares"); and

WHEREAS, the Company has loaned to Purchaser the amount of $150,000.00
which Purchaser has used to pay the purchase price of the Shares; and

WHEREAS, Purchaser has executed and delivered to the Company a
full-recourse Promissory Note evidencing such loan (the "Note") and has agreed
to pledge all of the Shares to the Company as security for the payment of the
Note:

NOW, THEREFORE, it is agreed as follows:

1. Purchaser hereby delivers to the Company one or more certificates
representing the Shares, together with two Assignments Separate From Certificate
endorsed in blank by the Purchaser. Purchaser hereby pledges and grants a
security interest in the Shares, including any shares into which the Shares may
be converted and all proceeds of the Shares, as security for the timely payment
of all of Purchaser's obligations under the Note and for Purchaser's performance
of all of its obligations under this Agreement. In the event of a default in
payment of the Note, Purchaser hereby appoints the Company as his true and
lawful attorney to take such action as may be necessary or appropriate to cause
the Shares to be transferred into the name of the Company or any assignee of the
Company and to take any other action on behalf of Purchaser permitted hereunder
or under applicable law.

2. The Company agrees to hold the Shares as security for the timely
payment of all of Purchaser's obligations under the Note and for Purchaser's
performance of all of its obligations under this Agreement, as provided herein.
At no time shall the Company dispose of or encumber the Shares, except as
otherwise provided in this Agreement.

3. At all times while the Company is holding the Shares as security under
this Agreement, the Company shall:

(a) Collect any dividends that may be declared on the Shares and
credit such dividends against any accrued interest or unpaid principal under the
Note, as part payment;

(b) Collect and hold any shares that may be issued upon conversion of
the Shares; and
<PAGE>

Such shares and other securities or property shall be subject to the security
interest granted in Section 1 of this Agreement and shall be held by the Company
under this Agreement.

4. While the Shares are pledged to the Company, as security under
this Agreement, Purchaser shall have the right to vote the Shares at all
meetings of the Company's stockholders; provided that Purchaser is not in
default in the performance of any material term of this Agreement or in any
payment due under the Note. In the event of such a default, the Company shall
have the right to the extent permitted by law to vote and to give consents,
recertifications and waivers and take any other action with respect to the
Shares with the same force and effect as if the Company were the absolute and
sole owner of the Shares.

5. Upon payment of all or part of the outstanding principal balance
of the Note and any interest and other charges due under the Note, the Company
shall release from pledge and redeliver to Purchaser the certificate(s)
representing the Shares for which payment has been received and the Assignment
Separate From Certificate forms.

6. Following ten (10) days prior written notice of Purchaser's
failure to perform any material term of this Agreement or failure to make any
payment when due under the Note, and Purchaser has not cured such failure within
the 10-day period, the Company shall have all of the rights and remedies of a
creditor and secured party at law and in equity, including (without limitation)
through a public or private sale or at any broker's board or on any securities
exchange, for cash, upon credit or for future deliver. The Company is authorized
at any such sale, if it deems it advisable to do so, to restrict the prospective
bidders or purchasers of any of the Shares to persons who will represent and
agree that they are purchasing for their own account for investment, and not
with a view to the distribution or sale of any of the Shares, to restrict the
prospective bidders or purchasers and the use any purchaser may make of the
Shares and impose any other restriction or condition that the Company deems
necessary or advisable under the federal and state securities laws. Upon any
such sale the Company shall have the right to deliver, assign and transfer to
Purchaser thereof the Shares so sold. Each purchaser at any such sale shall hold
the Shares so sold absolute, free from any claim or right of any kind. In case
of any sale of any or all of the Shares on credit or for future delivery, the
Shares so sold may be retained by the Company until the selling price is paid by
Purchaser thereof, but the Company shall not incur any liability in case of the
failure of such purchaser to take up and pay for the Shares to sold and, in case
of any such failure, such Shares may again be sold under the terms of this
section. Purchaser hereby agrees that any disposition of any or all of the
Shares by way of a private placement or other method which is in the opinion of
the Company is required or advisable under Federal and state securities laws is
commercially reasonable. At any public sale, the Company may (if it is the
highest bidder) purchase all or any part of the Shares at such price as the
Company deems proper. Out of the proceeds of any sale, the Company may retain an
amount sufficient to pay all amounts then due under the Note, together with the
expenses of the sale an reasonable attorneys' fees. The Company shall pay

<PAGE>

the balance of such proceeds, if any, to Purchaser. Purchaser shall be liable
for any deficiency that remains after the Company has exercised its rights under
this Agreement.

7. This Agreement shall be governed by and construed in accordance
with the laws of the State of California. This Agreement shall inure to the
benefit of, and be binding upon, the Company and its successors and assigns and
be binding upon Purchaser and Purchaser's legal representative, heirs, legatees,
distributees, assigns and transferees by operation of law. This Agreement
contains the entire security agreement between the Company and Purchaser.
Purchaser will execute any additional agreements, assignments or documents or
take any other actions reasonably required by the Company to preserve and
perfect the security interest in the Shares granted to the Company herein and
otherwise to effectuate this Agreement.

IN WITNESS WHEREOF, the Company has caused this Agreement to be
executed on its behalf by its duly authorized officer, and Purchaser has
personally executed this Agreement.

FOUNDER STOCK PURCHASE AGREEMENT
--------------------------------

THIS FOUNDER STOCK PURCHASE AGREEMENT is made as of this 31 day of August,
1996, by and between GMS DENTAL GROUP, INC., a Delaware corporation (the
----------------------
"Company"), and GRANT M.SADLER (the "Purchaser").
--------------

1. Purchase of Shares.
------------------

1.1 Purchase. Purchaser hereby purchases, and the Company hereby sells
--------
to Purchaser, 957,041 shares of the Company's Common Stock (the "Shares") at a
purchase price of $95,704.10 or $0.10 per share (the "Purchase Price")

1.2 Payment. Concurrently with the execution of this Agreement,
-------
Purchaser shall pay the Purchase Price for the Shares by full recourse
promissory note, in which case cash shall be paid to the extent of the par value
of the shares purchased with such promissory note. Purchaser shall also deliver
to the Secretary of the Company a duly executed blank Assignment Separate from
Certificate (in the form attached hereto as Exhibit A) and any additional
---------
documents required by the Company as a condition for the purchase. When and as
shares vest pursuant to Section 5.3, Purchaser shall receive a bonus from the
Company in the amount sufficient so that after payment of all federal and state
income and employment taxes, Purchaser retains an amount sufficient to make a
payment on the promissory note in an amount sufficient to release the vested
shares from the Security Agreement.

1.3 Delivery of Certificates. The certificates representing the Shares
------------------------
purchased hereunder and subject to the Company's Repurchase Right under Article
5 hereof shall be held in escrow by the Secretary of the Company as provided in
Article 5 hereof.

2. Securities Law Compliance.
-------------------------

2.1 Exemption From Registration. The Shares have not been registered
---------------------------
under the Securities Act of 1933, as amended (the "1933 Act") and are being
issued to Purchaser in reliance upon the exemption from such registration
provided by Rule 701 of the Securities and Exchange Commission (the
"Commission") for stock issuances under compensatory benefit arrangements such
as this Agreement. Purchaser hereby acknowledges receipt of a copy of this
Agreement.

2.2 Restricted Securities.
---------------------
(a) Purchaser hereby confirms that Purchaser has been informed that the
Shares are "restricted securities" under the

-1-

<PAGE>

1933 Act and may not be resold or transferred unless the Shares are first
registered under the federal securities laws or unless an exemption from such
registration is available. Accordingly, Purchaser hereby acknowledges that
Purchaser is prepared to hold the Shares for an indefinite period and that
Purchaser is aware that Rule 144 of the commission issued under the 1933 Act is
not presently available to exempt the sale of the Shares from the registration
requirements of the 1933 Act.

(b) Purchaser is aware of the adoption of Rule 144 by the Commission,
promulgated under the 1933 Act, which permits limited public resales of
securities acquired in a nonpublic offering, subject to the satisfaction of
certain conditions. Purchaser understands that under Rule 144, the conditions
include, among other things: the availability of certain current public
information about the issuer, the resale occurring not fewer than two (2) years
from the date the party purchased and paid for the securities to be sold, the
sale being through a broker in an unsolicited "broker's transaction" and the
amount of securities being sold during any three (3) month period not exceeding
specified limitations. Purchaser acknowledges and understands that the Company
may not be satisfying the current public information requirements of Rule 144
or other conditions under Rule 144 which are required of the Company at the time
Purchaser wishes to sell the Shares. If so, Purchaser understands that he will
be precluded from selling the securities under Rule 144, even if the two (2)
year holding period requirement of said Rule has been satisfied. Prior to
acquisition of the Shares, Purchaser acquired sufficient information about the
Company to reach an informed knowledgeable decision to acquire the Shares.
Purchaser has such knowledge and experience in financial and business matters as
to make him capable of evaluating the risks of the prospective investment and to
make an informed investment decision. Purchaser is able to bear the economic
risk of his investment in the Shares.

2.3 Disposition of Shares. Purchaser hereby agrees that Purchaser shall
---------------------
make no disposition of the Shares (other than a permitted transfer under Section
4.1) unless and until:

(a) Purchaser shall have notified the Company of the proposed
disposition and provided a written summary of the terms and conditions of
the proposed disposition;

(b) Purchaser shall have complied with all requirements of this
Agreement applicable to the disposition of the Shares; and

(c) Purchaser shall have provided the Company an opinion of counsel
in form and substance satisfactory to the Company, that (i) the proposed
disposition does not require registration of the Shares under the 1933 Act
or (ii) all appropriate action necessary for

-2-
<PAGE>

compliance with the registration requirements of the 1933 Act or
of any exemption from registration available under the 1933 Act
(including Rule 144) has been taken.

The Company shall not be required (i) to transfer on its books any Shares
that have been sold or transferred in violation of the provisions of this
Article 2 nor (ii) to treat as the owner of the Shares, or otherwise to accord
voting or dividend rights to, any transferee to whom the Shares have been
transferred in contravention of this Agreement.

2.4 Restrictive Legends. In order to reflect the restrictions on the
-------------------
disposition of the Shares, the stock certificates for the Shares will be
endorsed with restrictive legends, including one or both of the following
legends:

(a) "The securities represented by this certificate have
not been registered or qualified under the Securities Act of 1933
or the securities laws of any state, and may be offered and sold
only if registered and qualified pursuant to federal and state
securities laws or if the Company is provided an opinion of
counsel satisfactory to the Company that registration and
qualification under federal and state securities laws is not
required."

(b) If required by the authorities of any state in
connection with the issuance of the Shares, the legend or legends
required by such state authorities shall also be endorsed on all
such certificates.

3. Special Provisions.
------------------

3.1 Stockholder Rights. Until such time as the Company actually exercises
------------------
its repurchase rights under this Agreement, Purchaser (or any successor in
interest) shall have all the rights of a stockholder (including voting and
dividend rights) with respect to the Shares, including the Shares held in escrow
under Article 7, which are not subject to the vesting provisions set forth in
clause (iv) of Section 5.3. All shares are subject, however, to the transfer
restrictions of Article 4. Purchaser shall have no dividend rights with respect
to the shares which are subject to the vesting provisions of clause (iv) of
Section 5.3

3.2 Section 83(b) Election. Purchaser understands that under section 83 of
----------------------
the Internal Revenue Code of 1986, as amended (the "Code"), the difference
between the Purchase Price paid for the Shares and their fair market value on
the date any forfeiture restrictions applicable to such Shares lapse will be
reportable as ordinary income at that time. For this purpose, the term
"forfeiture restriction" includes the right of the Company to repurchase the
Unvested Shares under Article 5 of

-3-

<PAGE>

this Agreement. Purchaser understands that he may elect to be taxed at the time
the Shares are acquired hereunder to the extent the fair market value of the
Shares differs from the Purchase Price rather than when such Shares cease to be
subject to such forfeiture restrictions, by filing an election under section 83
(b) of the Code with the I.R.S. within thirty (30) days after the date of
purchase hereunder. The form for making this election is attached as Exhibit B
---------
hereto. Purchaser understands that failure to make this filing within the thirty
(30) day period will result in the recognition of ordinary income by Purchaser
(in the event the fair market value of the Shares increases after the date of
purchase) as the forfeiture restrictions lapse. PURCHASER ACKNOWLEDGES THAT IT
IS PURCHASER'S SOLE RESPONSIBILITY, AND NOT THE COMPANY'S, TO FILE A TIMELY
ELECTION UNDER SECTION 83(b), EVEN IF PURCHASER REQUESTS THE COMPANY OR ITS
REPRESENTATIVES TO MAKE THIS FILING ON HIS/HER BEHALF. PURCHASER IS RELYING
SOLELY ON HIS OR HER ADVISORS WITH RESPECT TO THE DECISION AS TO WHETHER OR NOT
- ------
TO FILE AN 83(b) ELECTION.

3.3 Market Stand-Off.
----------------

(a) If requested by the Company and an underwriter of Common Stock (or
other securities) of the Company, the Purchaser shall not pledge, sell, offer to
sell, contract to sell, grant any option to purchase, make any short sale of any
Common Stock of the Company, or any options or warrants to purchase any shares
of the Common Stock of the Company or any securities convertible into or
exchangeable for shares of Common Stock of the Company, whether now owned or
hereinafter acquired, owned directly by the Purchaser or with respect to which
the Purchaser has beneficial ownership within the rules and regulations of the
Commission (collectively, the "Purchaser Shares"); otherwise than (a) as a bona
fide gift or gifts, provided that the donee or donees thereof agree to be bound
by the restrictions set forth herein, (b) a transfer to any trust for the direct
or indirect benefit of the Purchaser or his or her immediate family provided
that the trustee of the trust agrees to be bound by the restrictions set forth
herein, held by the Purchaser during the one hundred eighty (180) day period
following the effective date of a registration statement of the Company filed
under the 1933 Act.

(b) In the event of any stock dividend, stock split, recapitalization or
other change affecting the Company's outstanding common Stock effected without
receipt of consideration, then any new, substituted or additional securities
distributed with respect to the Shares shall be immediately subject to the
provisions of this Section 3.3, to the same extent the Shares are at such time
covered by such provisions.

For purposes of this Section 3.3, "immediate family" shall mean any
relationship by blood, marriage or adoption, not more

-4-
<PAGE>

remote than first cousin. The Purchaser also agrees and consents to the entry of
stop transfer instructions with the Company's transfer agent and registrar
against the transfer of the Purchaser Shares except in compliance with the
foregoing restrictions.

The obligations described in this Section 3.3 shall not apply to a
registration statement relating solely to employee benefit plans on Form S-1 or
Form S-8 or similar forms that may be promulgated in the future, or a
registration relating solely to a Commission Rule 145 transaction on Form S-4 or
similar forms that may be promulgated in the future.

3.4 Stop Transfer. In order to enforce the provisions of Section 3.3, the
-------------
Company may impose stop-transfer instructions with respect to the Shares until
the end of the applicable stand-off period.

4. Transfer Restrictions.
---------------------

4.1 Restriction on Transfer. Purchaser shall not transfer, assign,
-----------------------
encumber, or otherwise dispose of any of the Shares that are subject to the
Company's Repurchase Right under Article 5. In addition, Shares that are
released from the Repurchase Right shall not be transferred, assigned,
encumbered, or otherwise made the subject of disposition in contravention of the
Company's First Refusal Right under Article 6. Such restrictions on transfer,
however, shall not be applicable if Purchaser receives prior written consent
from the Company to (i) a gratuitous transfer of the Shares made to Purchaser's
spouse or issue, including adopted children, or to a trust for the exclusive
benefit of Purchaser or Purchaser's spouse or issue, (ii) a transfer of title to
the Shares effected pursuant to Purchaser's will or the laws of intestate
succession, or (iii) a transfer to the Company in pledge as security for any
purchase-money indebtedness incurred by Purchaser in connection with the
acquisition of the Shares.

4.2 Transferee Obligations. Each person (other than the Company) to whom
----------------------
the Shares are transferred by means of one of the permitted transfers
specified in Section 4.1 must, as a condition precedent to such transfer,
acknowledge in writing to the Company that such person is bound by the
provisions of this Agreement and that the transferred shares are subject to (i)
both the Company's Repurchase Right and the Company's First Refusal Right
granted hereunder and (ii) the market stand-off provisions of Section 3.3, to
the same extent such shares would be so subject if retained by Purchaser.

4.3 Definition of Owner. For purposes of Articles 5, 6 and 7 of this
-------------------
Agreement, the term "Owner" shall include Purchaser and all subsequent holders
of the Shares who derive their chain of ownership through a permitted transfer
from Purchaser in accordance with Section 4.1.

-5-

<PAGE>

5. Repurchase Right.
----------------

5.1 Grant. The Company is hereby granted the right (the "Repurchase
-----
Right"), exercisable below) at any time during the sixty (60) day period
following the date Purchaser ceases to be a "Service Provider", to repurchase at
the Purchase Price all or (at the discretion of the Company and with the consent
of Purchaser) any portion of the Shares in which Purchaser has not acquired a
vested interest in accordance with Section 5.3 (the "Unvested Shares"). For
purposes of this Agreement, Purchaser shall be deemed to be a "Service Provider"
of the Company for so long as Purchaser renders services to the Company or one
or more of its parent or subsidiary corporations as an employee.

5.2 Exercise of the Repurchase Right and Termination of the Repurchase
------------------------------------------------------------------
Right. The Repurchase Right shall be exercisable by written notice delivered to
- -----
the Owner of the Shares prior to the expiration of the sixty (60) day period
specified in Section 5.1 (or, in certain cases, Section 5.4(b)). The notice
shall indicate the number of Shares to be repurchased and the date on which the
repurchase is to be effected, such date to be not more than thirty (30) days
after the date of notice. To the extent one or more certificates representing
Shares may have been previously delivered out of escrow to the Owner, then the
Owner shall, prior to the close of business on the date specified for the
repurchase, deliver to the Secretary of the Company the certificates
representing the Shares to be repurchased, properly endorsed for transfer. The
Company shall, concurrently with the receipt of such stock certificates, pay to
the Owner in cash or cash equivalents (including the cancellation of any
purchase-money indebtedness), an amount equal to the Purchase Price previously
paid for the Unvested Shares that are to be repurchased. The Repurchase Right
shall terminate with respect to any Shares for which it is not timely exercised
under Section 5.2. All Shares as to which the Repurchase Right lapses shall,
however, continue to be subject to (i) the First Refusal Right under Article 6,
(ii) the market stand-off provisions of Section 3.3 and (i) the transfer
restrictions set forth in Articles 2 and 4.

5.3 Vesting of Shares.
-----------------

Provided Purchaser continues to be a Service Provider of the Company,
Purchaser shall acquire a vested interest (i) with respect to 105,882 Shares on
the date hereof, (ii) with respect to 79,406 Shares on the first anniversary of
the date hereof, (iii) with respect to 6,617 Shares at the end of each month
beginning on the first anniversary of the date hereof, and (iv) with respect to
the remaining 533,541 Shares upon the earlier of the satisfaction of the
conditions set forth in Exhibit C or nine years and nine months from the date
hereof.

5.4 Fractional Shares. No fractional shares shall be repurchased by the
-----------------
Company. Accordingly, should the Repurchase

-6-
<PAGE>

Right extend to a fractional share at the time Purchaser ceases to be a Service
Provider of the Company, then such fractional share shall be added to any
fractional share in which Purchaser is at such time vested in order to make one
whole vested share no longer subject to the Repurchase Right.

5.5 Additional Shares or Substituted Securities. In the event of any stock
-------------------------------------------
dividend, stock split, recapitalization or other change affecting the Company's
outstanding Common Stock as a class effected without receipt of consideration,
then any new, substituted or additional securities or other property (including
money paid other than as a regular cash dividend) which is by reason of any such
transaction distributed with respect to the Shares shall be immediately subject
to the Repurchase Right, but only to the extent the Shares are at the time
covered by such right. Appropriate adjustments to reflect the distribution of
such securities or property shall be made to the number of Shares hereunder and
to the price per share to be paid upon the exercise of the Repurchase Right in
order to reflect the effect of any such transaction upon the Company's capital
structure.

6. Right of First Refusal.
----------------------

6.1 Grant. The Company is hereby granted the right of first refusal (the
-----
"First Refusal Right"), exercisable in connection with any proposed sale or
other transfer of the Shares in which Purchaser has vested in accordance with
Article 5. For purposes of this Article 6, the term "transfer" shall include any
assignment, pledge, encumbrance or other disposition for value of the Shares
intended to be made by the Owner, but shall not include any of the permitted
transfers under Section 4.1.

6.2 Notice of Intended Disposition. In the event the Owner desires to
------------------------------
accept a bona fide third-party offer for any or all of the Shares (the shares
subject to such offer to be hereinafter called, for purposes of this Article 6,
the "Target Shares"), the Owner shall promptly (i) deliver to the Secretary of
the Company written notice (the "Disposition Notice") of the offer and the basic
terms and conditions thereof, including the proposed purchase price, and (ii)
provide satisfactory proof that the disposition of the Target Shares to the
third-party offeror would not contravene the provisions of Articles 2 and 3 of
this Agreement.

6.3 Exercise of Right. The Company (or its assignees) shall, for a period
-----------------
of sixty (60) days following receipt of the Disposition Notice, have the right
to repurchase all or a portion of the Target Shares specified in the Disposition
Notice upon substantially the same terms and conditions specified therein. Such
right shall be exercisable by written notice (the "Exercise Notice") delivered
to the Owner prior to the expiration of the thirty (30) day exercise period. If
such

-7-
<PAGE>

right is exercised with respect to all the Target Shares specified in the
Disposition Notice, then the Company (or its assignees) shall effect the
repurchase of the Target Shares, including payment of the purchase price, not
more than five (5) business days after delivery of the Exercise Notice; and at
such time the Owner shall deliver to the Company the certificates representing
the Target Shares to be repurchased, properly endorsed for transfer. If any of
the Target Shares are at the time held in escrow under Article 7, the
certificates for such shares shall automatically be released from escrow and
surrendered to the Company for cancellation. The Target Shares so purchased
shall thereupon be canceled and cease to be issued and outstanding shares of the
Company's Common Stock.

Should the purchase price specified in the Disposition Notice be payable in
property other than cash or evidences of indebtedness, the Company (or its
assignees) shall have the right to pay the purchase price in the form of cash
equal in amount to the value of such property. If the Owner and the Company (or
its assignees) cannot agree on such cash value within ten (10) days after the
Company's receipt of the Disposition Notice, the valuation shall be made by an
appraiser of recognized standing selected by the Owner and the Company ( or its
assignees), or, if they cannot agree on an appraiser within twenty (20) days
after the Company's receipt of the Disposition Notice, each shall select an
appraiser of recognized standing and the two appraisers shall designate a third
appraiser of recognized standing, whose appraisal shall be determinative of such
value. The cost of such appraisal shall be shared equally by the Owner and the
Company. The closing shall then be held on the latter of (i) the fifth business
day following delivery of the Exercise Notice or (ii) the 15th day after such
cash valuation shall have been made.

6.4 Non-Exercise of Right. In the event the Exercise Notice is not given to
---------------------
the Owner within thirty (30) days following the date of the Company's receipt of
the Disposition Notice, the Owner shall have a period of thirty (30) days
thereafter, in which to sell or otherwise dispose of any or all of the Target
Shares upon terms and conditions (including the purchase price) no more
favorable to the third-party purchaser than those specified in the Disposition
Notice; provided that any such sale or disposition must not contravene the
provisions of Article 2 of this Agreement. If any of the Target Shares are at
the time held in escrow under Article 7, the certificates for such shares shall
automatically be released from escrow and surrendered to the Owner. The third-
party purchaser shall acquire the Target Shares free and clear of all the terms
and provisions of this Agreement (including the Company's Repurchase Right under
Article 5 and the First Refusal Right hereunder). If the Owner does not sell or
otherwise dispose of the Target Shares within the specified thirty (30) day
period, the Company's First Refusal Right shall continue to apply to any
subsequent dispo-

sition of the Target Shares by the Owner until such right lapses in accordance
with Section 6.7.

6.5 Partial Exercise of Right. In the event the Company (or its assignees)
-------------------------
makes a timely exercise of the First Refusal Right with respect to a portion,
but not all, of the Target Shares specified in the Disposition Notice, the Owner
shall sell to the Company (or its assignees) the portion of the Target Shares
which the Company (or its assignees) has elected to purchase, such sale to be
effected in substantial conformity with the provisions of Section 6.3 and sell
the remaining Target Shares to a third party purchaser, if so desired by Owner.

6.6 Recapitalization. In the event of any stock dividend, stock split,
----------------
recapitalization or other transaction affecting the Company's outstanding Common
Stock as a class effected without receipt of consideration, then any new,
substituted or additional securities or other property which is by reason of
such transaction distributed with respect to the Shares shall be immediately
subject to the Company's First Refusal Right hereunder, but only to the extent
the Shares are at the time covered by such right.

6.7 Lapse. The First Refusal Right under this Article 6 shall lapse and
-----
cease to have effect upon the earliest to occur of (i) the determination by the
Company's Board of Directors that a public market exists for the outstanding
shares of the Company's Common Stock, or (ii) the closing of a Qualified IPO.

6.8 Legend. In addition to the legends required by Section 2.4, all
------
certificates representing Shares subject to the Company's Right of Repurchase

"THE SECURITIES REPRESENTED BY THIS CERTIFICATE MAY NOT BE SOLD,
TRANSFERRED, ENCUMBERED OR IN ANY MANNER DISPOSED OF, EXCEPT IN
COMPLIANCE WITH THE TERMS OF A WRITTEN AGREEMENT BETWEEN THE COMPANY
AND THE INITIAL HOLDER HEREOF. SUCH AGREEMENT PROVIDES FOR
CERTAIN RESTRICTIONS ON TRANSFER OF THE SECURITIES, INCLUDING RIGHTS OF
FIRST REFUSAL UPON AN ATTEMPTED TRANSFER OF THE SECURITIES AND CERTAIN
REPURCHASE RIGHTS IN FAVOR OF THE COMPANY UPON TERMINATION OF SERVICE
WITH THE COMPANY. THE SECRETARY OF THE COMPANY WILL UPON WRITTEN
REQUEST FURNISH A COPY OF SUCH AGREEMENT TO THE HOLDER HEREOF WITHOUT
CHARGE."

7. Escrow.
------

7.1 Deposit. Upon issuance, the certificates for the Shares shall be
-------
deposited in escrow with the Secretary of the Company to be held in accordance
with the provisions of this Article 7. Each deposited certificate shall be

---------
securities from time to time deposited with the Company pursuant to the
requirements of this Agreement, shall remain in escrow until such time or times
as the certificates (or other assets and securities) are to be released or
otherwise surrendered for cancellation in accordance with Section 7.3. Upon
delivery of the certificates (or other assets and securities) to the Company,
the Owner shall be issued an instrument of deposit acknowledging the number of
Shares (or other assets and securities) delivered in escrow to the Secretary of
the Company.

7.2 Recapitalization. All regular cash dividends on the Shares (or other
----------------
securities at the time held in escrow) shall be paid directly to the Owner and
shall not be held in escrow. However, in the event of any stock dividend, stock
split, recapitalization or other change affecting the Company's outstanding
Common Stock as a class effected without receipt of consideration, any new,
substituted or additional securities or other property which is by reason of
such transaction distributed with respect to the Shares shall be immediately
delivered to the Secretary of the Company to be held in escrow under this
Article 7, but only to the extent the Shares are at the time subject to the
escrow requirements of Section 7.1.

-----------------
securities held in escrow hereunder, shall be subject to the following terms and
conditions relating to their release from escrow or their surrender to the
Company for repurchase and cancellation:

(a) Should the Company exercise the Repurchase Right under Article 5 with
respect to any Shares, then the escrowed certificates for such Shares (together
with any other assets or securities issued with respect thereto) shall be
delivered to the Company for cancellation, concurrently with the payment to the
Owner, in cash or cash equivalent (including the cancellation of any purchase-
money indebtedness), of an amount equal to the aggregate Purchase Price for
Unvested Shares, and the Owner shall have no further rights with respect to such
Shares (or other assets or securities).

(b) Should the Company exercise its First Refusal Right under Article 6
with respect to any Target Shares held at the time in escrow hereunder, then the
escrowed certificates for such Target Shares (together with any other assets or
securities issued with respect thereto) shall, concurrently with the payment of
the Section 6.3 purchase price for such Target Shares to the Owner, be
surrendered to the Company for cancellation, and the Owner shall have no further
rights with respect to such Target Shares (or other assets or securities).

(c) Should the Company elect not to exercise its First Refusal Right under
Article 6 with respect to any Target Shares held at the time in escrow
hereunder, then the escrowed certifi-

-10-
<PAGE>

cates for such Target Shares (together with any other assets or securities
issued with respect thereto) shall be surrendered to the Owner for disposition
according to the provisions of Section 6.4.

(d) As the interest of Purchaser in the Shares (or any other assets or
securities issued with respect thereto) vests in accordance with the provisions
of Article 5, the certificates for such vested Shares (as well as all other
vested assets and securities) shall be released from escrow and delivered to the
Owner.

(e) All Shares (or other assets or securities) released from escrow in
accordance with the provisions of subparagraph (d) above shall nevertheless
remain subject to the First Refusal Right under Article 6 and the market
stand-off provisions of Section 3.3 until such provisions terminate in
accordance herewith.

----------
Article 5 and/or its First Refusal Right under Article 6 to any person or entity
selected by the Company's Boards of Directors, including one or more
stockholders of the Company.

If the assignee of the Repurchase Right is other than a parent or
subsidiary corporation of the Company, then such assignee must take a cash
payment to the Company, upon the assignment of the Repurchase Right, in an
amount equal to the excess (if any) of the fair market value of the Unvested
Shares at the time subject to the Repurchase Right (as determined by the
Company's Board of Directors) and the aggregate Repurchase Price payable for
such Unvested Shares.

8.2 Definitions. For purposes of this Agreement, the following provisions
-----------
shall be applicable in determining the parent and subsidiary corporations of the
Company:

possessing fifty percent (50%) or more of the total combined voting power of all
classes of stock in one of the other corporations in such chain.

(b) Each corporation (other than the Company) in an unbroken chain of
corporations beginning with the Company shall be considered to be a subsidiary

---------------------------------
confer upon Purchaser any right to continue in the service of the Company (or
any parent or subsidiary corporation of the Company) for any period of time or

---------
instance to exercise the Repurchase Rights granted under Article 5, or the
failure of the Company (or its assignees) in any instance to exercise the First
Refusal Right granted under Article 6, shall not constitute a waiver of any
other repurchase rights and/or rights of first refusal that may subsequently
arise under the provisions of this Agreement or any other agreement between the
Company and Purchaser. No waiver of any breach or condition of this Agreement
shall be deemed to be a waiver of any other or subsequent breach or condition,
whether of like of different nature.

----------------------
available, at the time and place and in the amount and form provided in this

SECURITY AGREEMENT

THIS AGREEMENT, entered into as of August 31, 1996, between GMS DENTAL
----------
GROUP, INC., a Delaware corporation (the "Company"), and GRANT M. SADLER (the
- ----------- ---------------
"Purchaser").

W I T N E S S E T H:

WHEREAS, the Purchaser has purchased from the Company 957,041 shares of the
Company's Common Stock (the "Shares"); and

WHEREAS, the Company has loaned to the Purchaser the amount of $94,747.06
which the Purchaser has used to pay a portion of the purchase price of the
Shares; and

WHEREAS, the Purchaser has executed and delivered to the Company a full-
recourse promissory note evidencing such loan (the "Note") and has agreed to
pledge all of the Shares to the Company as security for the payment of the Note:

NOW, THEREFORE, it is agreed as follows:

1. The Purchaser hereby delivers to the Company one or more certificates
representing the Shares, together with two Assignments Separate From Certificate
signed by the Purchaser. The Purchaser hereby pledges and grants a security
interest in the Shares, including any shares into which the Shares may be
converted and all proceeds of the Shares, as security for the timely payment of
all of the Purchaser's obligations under the Note and for the Purchaser's
performance of all of its obligations under this Agreement. In the event of a
default in payment of the Note, the Purchaser hereby appoints the Company as his
true and lawful attorney to take such action as may be necessary or appropriate
to cause the Shares to be transferred into the name of the Company or any
assignee of the Company and to take any other action on behalf of the Purchaser
permitted hereunder or under applicable law.

2. The Company agrees to hold the Shares as security for the timely
payment of all of the Purchaser's obligations under the Note and for the
Purchaser's performance of all of its obligations under this Agreement, as
provided herein. At no time shall the Company dispose of or encumber the Shares,
except as otherwise provided in this Agreement.

3. At all times while the Company is holding the Shares as security under
this Agreement, the Company shall:

(a) Collect any dividends that may be declared on the Shares and
credit such dividends against any accrued interest or unpaid principal
under the Note, as part payment;

-1-
<PAGE>

(b) Collect and hold any shares that may be issued upon conversion of
the Shares; and

Such shares and other securities or property shall be subject to the security
interest granted in Section 1 of this Agreement and shall be held by the company
under this Agreement.

4. While the Company holds the Shares as security under this Agreement,
the Purchaser shall have the right to vote the Shares at all meetings of the
Company's stockholders; provided that the Purchaser is not in default in the
performance of any term of this Agreement or in any payment due under the Note.
In the event of such a default, the Company shall have the right to the extent
permitted by law to vote and to give consents, ratifications and waivers and
take any other action with respect to the Shares with the same force and effect
as if the Company were the absolute and sole owner of the Shares.

5. Upon payment in full of the outstanding principal balance of the Note
and all interest and other charges due under the Note, the Company shall release
from pledge and redeliver to the Purchaser the certificate(s) representing the
Shares and the Assignment Separate From Certificate forms.

6. In the event that the Purchaser fails to perform any term of this
Agreement or fails to make any payment when due under the Note, the Company
shall have all of the rights and remedies of a creditor and secured party at law
and in equity, including (without limitation) the rights and remedies provided
under the California Uniform Commercial Code. Without limiting the foregoing,
the Company may, after giving ten (10) days' prior written notice to the
Purchaser by certified mail at his residence or business address, sell any or
all of the Shares in such manner and for such price as the Company may
determine, including (without limitation) through a public or private sale or at
any broker's board or on any securities exchange, for cash, upon credit or for
future delivery. The Company is authorized at any such sale, if it deems it
advisable to do so, to restrict the prospective bidders or purchasers of any of
the Shares to persons who will represent and agree that they are purchasing for
their own account for investment, and not with a view to the distribution or
sale of any of the Shares, to restrict the prospective bidders or purchasers and
the use any purchaser may make of the Shares and impose any other restriction or
condition that the Company deems necessary or advisable under the federal and
state securities laws. Upon any such sale the Company shall have the right to
deliver, assign and transfer to the purchaser thereof the Shares so sold. Each
purchaser at any such sale shall hold the Shares so sold absolute, free from any
claim or right of any kind. In case of any sale of any or all of the Shares on

-2-
<PAGE>

credit or for future delivery, the Shares so sold may be retained by the Company
until the selling price is paid by the purchaser thereof, but the Company shall
not incur any liability in case of the failure of such purchaser to take up and
pay for the Shares so sold and, in case of any such failure, such Shares may
again be sold under the terms of this section. The Purchaser hereby agrees that
any disposition of any or all of the Shares by way of a private placement or
other method which in the opinion of the Company is required or advisable under
Federal and state securities laws is commercially reasonable. At any public
sale, the Company may (if it is the highest bidder) purchase all or any part of
the Shares at such price as the Company deems proper. Out of the proceeds of any
sale, the Company may retain an amount sufficient to pay all amounts then due
under the Note, together with the expenses of the sale and reasonable attorneys'
fees. The Company shall pay the balance of such proceeds, if any, to the
Purchaser. The Purchaser shall be liable for any deficiency that remains after
the Company has exercised its rights under this Agreement.

7. This Agreement shall be governed by and construed in accordance with
the laws of the State of California. This Agreement shall inure to the benefit
of, and be binding upon, the Company and its successors and assigns and be
binding upon the purchaser and the Purchaser's legal representative, heirs,
legatees, distributees, assigns and transferees by operation of law. This
Agreement contains the entire security agreement between the Company and the
Purchaser. The Purchaser will execute any additional agreements, assignments or
documents or take any other actions reasonably required by the Company to
preserve and perfect the security interest in the Shares granted to the Company
herein and otherwise to effectuate this Agreement.

IN WITNESS WHEREOF, the Company has caused this Agreement to be executed on
its behalf by its duly authorized officer, and the Purchaser has personally
executed this Agreement.

two (2) year period described in Exhibit A attached hereto and made a part
hereof or (b) nine (9) years and nine (9) months from the date of issuance.

3. The Repurchase Right shall be exercised by written notice signed by an
officer of the Corporation and delivered or mailed as provided in Section 11 of

4. (a) To ensure the availability for delivery of Purchasers' shares upon

(b) Within ten (10) days after the last day of each full calendar year
after the Closing Date, if Purchaser so requests, the Escrow Agent will deliver
to Purchaser certificates representing the shares of vested Vesting Stock and
those shares of Repurchase Right Stock as are no longer subject to the
Repurchase Right (less such shares as have been previously delivered).

5. Escrow Agent shall be obligated only for the performance of such
duties as are specifically set forth herein and he or she may rely and shall be
protected in relying or refraining from acting on any instrument reasonably
believed by him or her to be genuine and to have been signed or presented by the

of Purchaser while acting in good faith and in the exercise of his or her own
good judgment, and any act done or omitted by him or her pursuant to the advice
of his or her own attorneys shall be conclusive evidence of such good faith. The
Escrow Agent's duties hereunder may be altered, amended, modified or revoked

6. The corporation shall not be required (a) to transfer on its books any
shares of Stock of the Corporation which shall have been sold or transferred in

property distributed, other than cash dividends on such shares, on account of
such stock, all of which shall be subject to the Escrow hereunder.

9. The parties agree to execute such further instruments and to take
such further action as may reasonably be necessary to carry out the intent of
this Agreement.

10. Any notice required or permitted hereunder shall be given in writing
and shall be deemed effectively given upon the earliest of personal delivery,
receipt or the third full day following deposit in the United States Post

address hereinafter shown below such party's signature or at such other address
as such party may designate by ten (10) days advance written notice to the other
party hereto.

11. This Agreement shall inure to the benefit of the successors and
assigns of the Corporation and, subject to the restrictions on transfer herein
set forth, be binding upon Purchasers and Purchasers heirs, executors,
administrators, successors and assigns. The failure of the Corporation in any
instance to exercise the Repurchase Right described herein shall not constitute
a waiver of any other Repurchase Option or right of first offer that may
subsequently arise under the provisions of this Agreement. No waiver of any
breach or condition of this Agreement shall be deemed to be a waiver of any
other or subsequent breach or condition, whether of a like or different nature.

12. This Agreement shall be governed by and construed in accordance with
the substantive laws of the State of California, except with respect to choice

notwithstanding anything to the contrary provided in the Founder Stock Purchase
Agreements, the Shares are subject to the Repurchase Rights as described in the
Escrow Agreement and to clarify that following the Merger, the shares of GDSC

495,431 and 266,770 Shares, respectively, for Mr. Sadler and Mr. Davis) shall be
governed by the Escrow Agreement, as modified by the Revised Milestones, and

Provider (as defined in the Founder Stock Purchase Agreements); provided,
however, the parties hereby acknowledge and agree that the Repurchase Rights
with respect to the Repurchase Rights Stock shall not become exercisable by the
Company unless and until there is a failure of the Company to achieve the

the Shareholders will receive in the Merger in exchange for the Shares will be
subject to the Repurchase Rights as clarified hereby.

computer programs (whether or not completed or in use) and any and all
operating manuals or similar materials which constitute the non-medical systems,
policies and procedures, and methods of doing business developed by or for the
operation of facilities managed by Manager. Dental Group acknowledges and
agrees that Manager has a proprietary interest in all such Proprietary
Information and that all such information constitutes confidential and
proprietary information and is the trade secret property of Manager. Dental
Group hereby waives any and all right, title and interest in and to such
Proprietary Information and agrees to return all copies thereof and Proprietary
Information related thereto to Manager, at Dental Group's expense, upon the
termination of this Agreement.

Dental Group further acknowledges and agrees that Manager is entitled to

consistent with the Annual Budget of the Practice (prepared as provided in
Section 3.6 hereof), the Management Fee as provided in Exhibit 7.1 hereto and

percent (1%) above the prime rate reported by the Wall Street Journal as
adjusted on a quarterly basis, compounded monthly until all such amounts of

------------------
hereunder and subject to applicable law, Group shall execute a Security
Agreement in substantially the form attached hereto as Exhibit 7.4 (the

performing its obligations pursuant to Article IV, Manager shall apply funds of
Group in the following order of priority:

a. payment of all Group Expenses;

b. payment of all Practice Expenses;

c. payment of the Management Fee; and

d. payment of amounts advanced to Group, and applicable
interest thereon (as contemplated in Section 7.3).

-------------------
business day of each month, Manager may purchase all or any portion the accounts
receivable of Group relating to Revenues arising during the previous month, by
payment of cash or other readily available funds into an account for Group or by
offset of amounts owed by Group to Manager. The consideration for the purchase
shall be an amount equal to all fees recorded each month (net of adjustments for
uncollectible accounts, professional courtesies and other such activities that
do not generate a collectible fee) less Management Fees due to Manager under
this Article VII. Manager's purchase shall be effective upon full payment of
the purchase price. In the event that such purchase shall be ineffective for
any reason, Group is concurrently herewith entering into the Security Agreement
to grant a security interest in the accounts receivable to Manager. In
addition, Group shall cooperate with Manager and execute all necessary documents
in connection with the pledge of such accounts receivable to Manager or at
Manager's option, its lenders. All collections in respect of such accounts
receivable shall be deposited in a bank account at a bank selected by mutual
agreement of Group and Manager. To the extent Group comes into possession of
any payments in respect of such accounts receivable, Group shall direct such
payments to Manager for deposit.

RESTRICTIVE COVENANTS
---------------------

10.1 Covenant Regarding Proprietary Information. In the course of the
------------------------------------------
relationship created pursuant to this Agreement, Group will have access to
certain methods, trade secrets, processes, ideas, systems, procedures,
inventions, discoveries, concepts, software in various stages of development,
designs, drawings, specifications, models, data, documents, diagrams, flow
charts, research, economic and financial analysis, developments, procedures,
know-how, policy manuals, form contracts, marketing and other techniques, plans,
materials, forms, copyrightable materials and trade information (all of which is
referred to in this Agreement as "Proprietary Information") regarding the
operations of Manager and/or of its Affiliates (collectively, the "Protected
Parties"). Group shall maintain all such Proprietary Information in strict
secrecy and shall not divulge such information to any third parties, except as
may be necessary for the discharge of their obligations under this Agreement.
Group shall take all necessary and proper precautions against disclosure of any
Proprietary Information to unauthorized persons by any of its employees or
agents. Group and all employees, and agents of Group who will have access to
all or any part of the Proprietary Information may be required to execute an
agreement, at the request of Manager, valid under the law of the jurisdiction in
which such agreement is executed, and in a form acceptable to Manager and its
counsel, committing themselves to maintain the Proprietary Information in strict
confidence and not to disclose it to any unauthorized person or entity. The
Protected Parties not party to this Agreement are hereby specifically made third
party beneficiaries of this Section, with the power to enforce the provisions
hereof. Upon termination of this Agreement for any reason, Group and each of
its Employee Providers and Subcontract Providers shall cease all use of any of
the Proprietary Information and, at the request of Manager, shall execute such
documents as may be necessary to evidence Group's abandonment of any claim
thereto. The parties recognize that a breach of this Section cannot be
adequately compensated in money damages and therefore agree that injunctive
relief shall be available to the Protected Parties as their respective interests
may appear.

The obligations of Group under this Section 10.1 shall not apply to
information: (i) which is a matter of public knowledge on or becomes a matter
of public knowledge after the Effective Date of this Agreement, other than as a
breach of the confidentiality terms of this Agreement or as a breach of the
confidentiality terms of any other agreement between Group and Manager or its
Affiliates; or (ii) which was lawfully obtained by Group on a nonconfidential
basis other than in the course of performance under this Agreement and from some
entity other than Manager or its Affiliates or from some person other than one
employed or engaged by Manager or its Affiliates, which entity or person has no
obligation of confidentiality to Manager or its Affiliates.

10.2 Covenants Not to Compete During the Term. The parties recognize
----------------------------------------
that the services to be provided by Manager shall be feasible only if Group
operates an active dental practice to which Group and Clinical Staff devote full
time and attention. To that end:

21.
<PAGE>

a. Restrictive Covenants by Group. During the term of this
------------------------------
Agreement, Group shall not (i) establish, operate or provide dental care
services at any dental office, clinic or other facility providing services
substantially similar to those provided by Group pursuant to this Agreement
anywhere other than at the Practice Sites and as may be approved in writing by
Manager; (ii) enter into any management or administrative services agreement or
other similar arrangement with any person or entity other than Manager without
Manager's prior written approval and (iii) operate or, directly or indirectly,
hold or own any type of ownership or other form of equity interest in, or serve
as a consultant to or otherwise perform services for any person or entity
engaged in the business of providing management and administrative services to
dental practices.

b. Restrictive Covenants by Providers. Unless otherwise agreed
----------------------------------
to in writing by Manager, Group shall use its best efforts to obtain and enforce
formal agreements with its Employee Providers and Subcontract Providers who are
dentists not to establish, operate or provide dental care services, during the
term of this Agreement and for a period of two (2) years after any termination
of employment with Group, at any dental office, clinic or facility located
within 20 miles of any Practice Site at which the Employee Provider or
Subcontract Provider has practiced. Any variation of such restrictive covenants
shall be approved in advance in writing by Manager.

10.3 Covenant Not to Solicit. For two (2) years following the
-----------------------
termination of this Agreement, Group shall not:

a. directly or indirectly solicit, recruit or hire, or induce
any party to solicit, recruit or hire any person who is an employee of, or who
has entered into an independent contractor arrangement with, Manager or any
Affiliate of Manager;

b. directly or indirectly, whether for himself or for any other
person or entity, call upon, solicit, divert or take away, or attempt to
solicit, call upon, divert or take away any of Manager's customers, business, or
clients; or

c. directly or indirectly solicit, or induce any party to
solicit, any of Manager's contractors or the contractors of any Affiliate of
Manager, to enter into the same or a similar type of contract with any other
party.

10.4 Enforcement. Manager and Group acknowledge and agree that since
-----------
a remedy at law for any breach or attempted breach of the provisions of this
Article X shall be inadequate, either party shall be entitled to specific
performance and injunctive or other equitable relief in case of any such breach
or attempted breach, in addition to whatever other remedies may exist by law.
All parties hereto also waive any requirement for the securing or posting of any
bond in connection with the obtaining of any such injunctive or other equitable

Group or by offset of amounts owed by Group to Manager. The consideration for
the purchase shall be an amount equal to all fees recorded each month (net of
adjustments for uncollectible accounts, professional courtesies and other such
activities that do not generate a collectible fee) less Management Fees due to
Manager under this Article VII. Manager's purchase shall be effective upon full

Group, at any dental office, clinic or facility located within a minimum of ten

performance and injunctive or other equitable relief in case of any such breach
or attempted breach, in addition to whatever other remedies may exist by law.

RESTRICTIVE COVENANTS

secrecy and shall not divulge such information to any third parties, except as
may be necessary for the discharge of their obligations under this Agreement.
Group shall take all necessary and proper precautions against disclosure of any

agreement, at the request of Manager, valid under the law of the jurisdiction in
which such agreement is executed, and in a form acceptable to Manager and its

confidence and not to disclose it to any unauthorized person or entity. The
Protected Parties not

17.
<PAGE>

party to this Agreement are hereby specifically made third party beneficiaries
of this Section, with the power to enforce the provisions hereof. Upon
termination of this Agreement for any reason, Group and each of its Employee
Providers and Subcontract Providers shall cease all use of any of the
Proprietary Information and, at the request of Manager, shall execute such
documents as may be necessary to evidence Group's abandonment of any claim
thereto. The parties recognize that a breach of this Section cannot be
adequately compensated in money damages and therefore agree that injunctive
relief shall be available to the Protected Parties as their respective interests
may appear.

Section 10.2 Covenants Not to Compete During the Term. The parties
----------------------------------------
recognize that the services to be provided by Manager shall be feasible only if
Group operates an active dental practice to which Group and Clinical Staff
devote full time and attention. To that end:

a. Restrictive Covenants by Group. During the term of this
------------------------------
Agreement and except as otherwise agreed to in writing by Manager, Group shall
not (i) establish, operate or provide dental care services at any dental office,
clinic or other facility providing services substantially similar to those
provided by Group pursuant to this Agreement anywhere other than at the Practice

management or administrative services agreement or other similar arrangement
with any person or entity other than Manager without Manager's prior written
approval and (iii) operate or, directly or indirectly, hold or own any type of
ownership or other form of equity interest in, or serve as a consultant to or
otherwise perform services for any person or entity engaged in the business of
providing management and administrative services to dental practices; provided,
however, that nothing in this Agreement shall prohibit Provider from
establishing, owning, organizing, opening, operating, participating in, working,
managing, advising, teaching, or from being in any way involved, affiliated or
associated with a dental school or with a dental hygienist school, whether now
existing or hereafter organized, public or private, so long as such activity by
Provider does not detract from Provider's obligations to perform services in
accordance with this Agreement, including, without limitation, the provision of
dental services for the number of hours described in Section 2.1 hereof.

b. Restrictive Covenants by Providers. Group shall use its
----------------------------------
best efforts to obtain and enforce formal agreements with its Employee Providers

caused by a material breach by Manager which shall remain uncured for a period
of sixty (60) days after receipt of notice in accordance with Section 11.4
hereof, or by nonpayment of a material amount owed by Manager to or to be paid
by Manager on behalf of Group), at any dental office, clinic or facility located
within 20 miles of any Practice Site at which the Employee Provider or
Subcontract Provider has practiced. Any variation of such restrictive covenants
shall be approved in advance in writing by Manager.

-----------------------
the termination of this Agreement, except for a valid termination by Group
pursuant to Section 6.2(b), Group shall not:

---------------
other proceeding is commenced, whether by Manager or Group concerning this
Agreement, the prevailing party shall recover form the losing party reasonable
attorneys' fees and costs and expenses, including those of appeal and not
limited to taxable costs, incurred by the prevailing party, in addition to all
other remedies to which the prevailing party may be entitled. If a claim or
claims asserted by a third party against Manager or Group or any of them arise
from an act or omission by the other, the party responsible for the act or
omission shall be the losing party, and the other party shall be the prevailing
party, for purposes of the foregoing sentence.

Section 11.6 Successors. Without limiting or otherwise affecting any

restrictions on assignments of this Agreement or rights or duties under this
Agreement, this Agreement shall be binding upon and inure to the benefit of the

Section 11.7 Entire Agreement. This Agreement sets forth the entire
----------------
agreement between Group and Manager and supersedes all prior negotiation and
agreements, written or oral, concerning or relating to the subject matter of
this Agreement, and this Agreement may not be modified except by a writing
executed by all parties and subject to the provisions thereof.

Section 11.8 Governing Law. This Agreement and the rights and
-------------
obligations of the parties hereto shall be governed by, and construed according
to, the laws of the State of California.

Section 11.9 Severability, Contract Modifications for Prospective
----------------------------------------------------
Legal Events. Nothing contained in this Agreement shall be construed to require
- ------------
the commission of an act contrary to law, and whenever there is any conflict
between any provision of this Agreement and any statute, law, ordinance or
regulation, the latter shall prevail. In such event, and in any case in which
any provision of this Agreement is determined to be in violation of a statute,
law, ordinance or regulation, the affected provision(s) shall be limited only to
the extent necessary to bring it within the requirements of the law and, insofar
as possible under the circumstances, to carry out the purposes of this
Agreement. The other provisions of this Agreement shall remain in full force and
effect, and the invalidity or unenforceability of any provision hereof shall not
affect the validity and enforceability of the other provisions of this
Agreement, nor the availability of all remedies in law or equity to the parties
with respect to such other provisions.

In the event any state or federal laws or regulations, now existing or
enacted or promulgated after the effective date of this Agreement, are
interpreted by judicial decision, a regulatory agency or legal counsel of both
parties in such a manner as to indicate that the structure of this Agreement may
be in violation of such laws or regulations, Group and Manager shall amend this
Agreement, to the maximum extent possible, to preserve the underlying economic
and financial arrangements between Group and Manager. In the event legal counsel
of both parties disagree as to whether the structure or any provision of this
Agreement may be in violation of applicable laws and regulations and one of the
parties therefore refuses to amend this Agreement in light of the reasonable
concerns of the other party and such party's legal counsel, then such party
refusing to amend shall indemnify and hold harmless the other party for any and
all harm and damages caused by or related to the offending provision. A party to
this

20.

Agreement may choose to, but shall not be required to, take any action or to
make any amendment to this Agreement if such action or amendment would put them
in a substantially and materially worse economic or financial position than that
contemplated by the terms of this Agreement. The parties acknowledge that such
amendment may require reorganization of Group or Manager, or both, and may
require either or both parties to obtain appropriate regulatory licenses and
approvals. If an amendment is not possible, either party shall have the right
to terminate this Agreement upon thirty (30) days notice to the other party.

or as of the last day of the applicable Interest Period, in the case of LIBOR
Loans, to convert any such Loans (or any part thereof in an amount not less than
$1,000,000, or that is in an integral multiple of $500,000 in excess thereof);
provided, however, that if at any time the aggregate amount of LIBOR Loans in
respect of any Borrowing is reduced, by payment, prepayment, or conversion of
part thereof to be less than $1,000,000, such LIBOR Loans shall automatically

into Prime Rate Loans effective as of the expiration date of such Interest

Loans with respect to which the notice was given held by each Bank.

of a Default or Event of Default, the Borrower may not elect to have a Loan be
made as or converted into or continued as a LIBOR Loan.

made on the effective date thereof, the then outstanding principal amount of the
Loans would exceed the amount of the Combined Commitments then in effect. Once
reduced in accordance with this Section 2.5, the Combined Commitments may not be
increased. Any reduction of the Combined Commitments shall be applied to each
Bank according to its Pro Rata Share. All accrued unused commitment fees due and

prepayment. If such notice is given by the Borrower, the Borrower shall make
such prepayment and the payment amount specified in such notice shall be due and
payable on the date specified therein, together with, in the case of LIBOR Loans
only, accrued interest to each such date on the amount prepaid and any amounts

amount thereof from the applicable Borrowing Date at a rate per annum equal to

Borrower's right to convert to other Types of Loans under Section 2.4), plus the
Applicable Margin.

(b) Interest on each Loan shall be paid in arrears on each Interest
Payment Date. Interest shall also be paid on the date of conversion to another
Type of Loan, on the date of any prepayment for the portion of the Loans so
prepaid and upon payment (including prepayment) in full thereof and, during the
existence of any Event of Default, interest shall be paid on demand of the Agent
at the request or with the consent of the Majority Banks.

(c) Notwithstanding Section (a) of this Section, while any Event of
Default exists or after acceleration, the Borrower shall pay interest (after as

principal amount of all outstanding Obligations, at a rate per annum which is
determined by adding 2% per annum, to the Applicable Margin then in effect for
such Loans; provided, however, that, on and after the expiration of any Interest
Period applicable to any LIBOR Loan outstanding on the date of occurrence of
such Event of Default or acceleration, the principal amount of such Loan shall,
during the continuation of such Event of Default or after acceleration, bear
interest at a rate per annum equal to the Prime Rate, plus Applicable Margin
plus 2%.

(d) Anything herein to the contrary notwithstanding, the obligations
of the Borrower to any Bank hereunder shall be subject to the limitation that
payments of interest shall not be required for any period for which interest is
computed hereunder, to the extent (but only to the extent) that contracting for
or receiving such payment by such Bank would be contrary to the provisions of
any law applicable to such Bank limiting the highest rate of interest that may
be lawfully contracted for, charged or received by such Bank, and in such event
the Borrower shall pay such Bank interest at the highest rate permitted by
applicable law.

time. Such commitment fee shall be payable in arrears on the last Business Day
of each calendar quarter and on the Revolving Termination Date.

accrue during each period during which interest or such fees are computed from
the first day thereof to the last day thereof.

(b) Each determination of an interest rate by the Agent shall be
conclusive and binding on the Borrower and the Banks in the absence of manifest

(c) Unless the Agent receives notice from the Borrower prior to the
date on which any payment is due to the Banks that the Borrower will not make
such payment in full as and when required, the Agent may assume that the
Borrower has made such payment in full to the Agent on such date in immediately
available funds and the Agent may (but shall not be so required), in reliance
upon such assumption, distribute to each Bank on such due date an amount equal
to the amount then due such Bank. If and to the extent the Borrower has not made
such payment in full to the Agent, each Bank, shall repay to the Agent on demand
such amount distributed to such Bank, together with interest thereon at the
Federal Funds Rate for each day from the date such amount is distributed to such
Bank until the date repaid.

2.12 Payments by the Banks to the Agent.

(a) Unless the Agent receives notice from a Bank on or prior to the
Closing Date or, with respect to any Borrowing after the Closing Date, at least
one Business Day prior to the date of such Borrowing, that such Bank will not
make available as and when required hereunder to the Agent for the account of
the Borrower the amount of that Bank's Pro Rata Share of the Borrowing, the
Agent may assume that each Bank has made such amount available to the Agent in
immediately available funds on the Borrowing Date and the Agent may (but shall
not be so required), in reliance upon such assumption, make available to the
Borrower on such date a corresponding amount. If and to the extent any Bank
shall not have made its full amount available to the Agent in immediately
available funds and the Agent in such circumstances has made available to the
Borrower such amount, such Bank and the Borrower severally agree to repay to the
Agent forthwith on demand such corresponding amount, together with interest
thereon, for each day from the date such amount is made available to the
Borrower until the date such amount is repaid to the Agent, (i) in the case of
the Borrower, at a rate per annum equal to the interest rate applicable at the
time to the Loans comprising such Borrowing and (ii) in the case of such Bank,
at the Federal Funds Rate for each day during such period. A notice of the Agent
submitted to any Bank and the Borrower with respect to amounts owing under this
Section 2.12(a) shall be conclusive, absent manifest error. If such Bank shall
repay to the Agent such corresponding amount, such payment so repaid shall
constitute such Bank's Loan as part of such Borrowing for all purposes of this
Agreement.

(b) The failure of any Bank to make any Loan on any Borrowing Date
shall not relieve any other Bank of any obligation hereunder to make a Loan on
such Borrowing Date, but no Bank shall be responsible for the failure of any
other Bank to make the Loan to be made by such other Bank on any Borrowing Date.
The Borrower reserves the right to seek compensation from any Bank wrongfully
failing to make a Loan on a Borrowing Date for any costs, losses and expenses
incurred by the Borrower resulting from such failure.
<PAGE>

2.13 Sharing of Payments, Etc. If, other than as expressly provided
elsewhere herein, any Bank shall obtain on account of the Loans made by it any
payment (whether voluntary, involuntary, through the exercise of any right of
set-off, or otherwise) in excess of its Pro Rata Share, such Bank shall
immediately (a) notify the Agent of such fact, and (b) purchase from the other
Banks such participations in the Loans made by them as shall be necessary to
cause such purchasing Bank to share the excess payment pro rata with each of
them; provided, however, that if all or any portion of such excess payment is
thereafter recovered from the purchasing Bank, such purchase shall to that
extent be rescinded and each other Bank shall repay to the purchasing Bank the
purchase price paid therefor, together with an amount equal to such paying
Bank's ratable share (according to the proportion of (i) the amount of such
paying Bank's required repayment to (ii) the total amount so recovered from the
purchasing Bank) of any interest or other amount paid or payable by the
purchasing Bank in respect of the total amount so recovered. The Borrower agrees
that any Bank so purchasing a participation from another Bank may, to the
fullest extent permitted by law, exercise all its rights of payment (including
the right of set-off, but subject to Section 10.10) with respect to such
participation as fully as if such Bank were the direct creditor of the Borrower
in the amount of such participation. The Agent will keep records (which shall be
conclusive and binding in the absence of manifest error) of participations
purchased under this Section and will in each case notify the Banks following
any such purchases or repayments.

2.14 Security Documents. The Obligations shall be (a) unconditionally
guaranteed as set forth in a Guaranty to be executed and delivered by GMS
Holding and each of its Subsidiaries (other than the Borrower) (as amended,
modified or supplemented from time to time, the "Guaranty") in the form of
Exhibit B attached hereto and (b) secured by a Security Agreement to be executed
and delivered by each of GMS Holding, the Borrower and by each of the other
Subsidiaries of GMS Holding (as amended, modified or supplemented from time to
time, the "Security Agreement") in the form of Exhibit C attached hereto.

ARTICLE III
TAXES, YIELD PROTECTION AND ILLEGALITY

3.1 Taxes. (a) Any and all payments by the Borrower to each Bank or the
Agent under this Agreement and any other Loan Document shall be made free and
clear of, and without deduction or withholding for any Taxes. In addition, the
Borrower shall pay all Other Taxes.

(b) The Borrower agrees to indemnify and hold harmless each Bank and
the Agent for the full amount of Taxes or Other Taxes (including any Taxes or
Other Taxes imposed by any
<PAGE>

jurisdiction on amounts payable under this Section) paid by the Bank or the
Agent and any liability (including penalties, interest, additions to tax and
expenses) arising therefrom or with respect thereto, whether or not such Taxes
or Other Taxes were correctly or legally asserted. Payment under this
indemnification shall be made within thirty (30) days after the date the Bank or
the Agent makes written demand therefor.

(c) If the Borrower shall be required by law to deduct or withhold
any Taxes or Other Taxes from or in respect of any sum payable hereunder to any
Bank or the Agent, then:

(i) the sum payable shall be increased as necessary so that
after making all required deductions and withholdings (including deductions and
withholdings applicable to additional sums payable under this Section) such Bank
or the Agent, as the case may be, receives an amount equal to the sum it would
have received had no such deductions or withholdings been made;

(ii) the Borrower shall make such deductions and withholdings;

(iii) the Borrower shall pay the full amount deducted or
withheld to the relevant taxing authority or other authority in accordance with
applicable law; and

(iv) the Borrower shall also pay to each Bank or the Agent for
the account of such Bank at the time interest is paid, all additional amounts
which the respective Bank specifies as necessary to preserve the after-tax yield
the Bank would have received if such Taxes or Other Taxes had not been imposed.

(d) Within thirty (30) days after the date of any payment by the
Borrower of Taxes or Other Taxes, the Borrower shall furnish the Agent the
original or a certified copy of a receipt evidencing payment thereof, or other
evidence of payment satisfactory to the Agent.

(e) If the Borrower is required to pay additional amounts to any
Bank or the Agent pursuant to subsection (c) of this Section, then such Bank
shall use reasonable efforts (consistent with legal and regulatory restrictions)
to change the jurisdiction of its Lending Office so as to eliminate any such
additional payment by the Borrower which may thereafter accrue, if such change
in the judgment of such Bank is not otherwise disadvantageous to such Bank.

3.2 Illegality.

(a) If any Bank determines that the introduction of any Requirement
of Law, or any change in any Requirement of Law, or in the interpretation or
administration of any Requirement of Law, has made it unlawful, or that any
central bank or other
<PAGE>

Governmental Authority has asserted that it is unlawful, for any Bank or its
applicable Lending Office to make LIBOR Loans, then, on notice thereof by the
Bank to the Borrower through the Agent, any obligation of that Bank to make
LIBOR Loans shall be suspended until the Bank notifies the Agent and the
Borrower that the circumstances giving rise to such determination no longer
exist.

(b) If a Bank determines that it is unlawful to maintain any LIBOR
Loan, the Borrower shall, upon its receipt of notice of such fact and demand
from such Bank (with a copy to the Agent), prepay in full such LIBOR Loans of
that Bank then outstanding, together with interest accrued thereon and amounts
required under Section 3.4, either on the last day of the Interest Period
thereof, if the Bank may lawfully continue to maintain such LIBOR Loans to such
day, or immediately, if the Bank may not lawfully continue to maintain such
LIBOR Loan. If the Borrower is required to so prepay any LIBOR Loan, then
concurrently with such prepayment, the Borrower shall borrow from the affected
Bank, in the amount of such repayment, a Prime Rate Loan.

(c) If the obligation of any Bank to make or maintain LIBOR Loans
has been so terminated or suspended, the Borrower may elect, by giving notice to
the Bank through the Agent that all Loans which would otherwise be made by the
Bank as LIBOR Loans shall be instead Prime Rate Committee Loans.

(d) Before giving any notice to the Agent under this Section, the
affected Bank shall designate a different Lending Office with respect to its
LIBOR Loans if such designation will avoid the need for giving such notice or
making such demand and will not, in the judgment of the Bank, be illegal or
otherwise disadvantageous to the Bank.

3.3 Increased Costs and Reduction of Return.

(a) If any Bank determines that, due to either (i) the introduction
of or any change in or in the interpretation of any law or regulation or (ii)
the compliance by that Bank with any guideline or request from any central bank
or other Governmental Authority (whether or not having the force of law), there
shall be any increase in the cost to such Bank of agreeing to make or making,
funding or maintaining any LIBOR Loans then, in any such case, such Bank shall
notify the Borrower of any such event of which it has knowledge and shall
deliver to the Agent and the Borrower a written statement specifying in
reasonable detail the losses or expenses sustained or incurred. The Borrower
shall within ten (10) days following demand therefor, pay the amount sufficient
to compensate such Bank for such increased costs.

(b) If any Bank shall have determined that (i) the introduction of
any Capital Adequacy Regulation, (ii) any change
<PAGE>

in any Capital Adequacy Regulation, (iii) any change in the interpretation or
administration of any Capital Adequacy Regulation by any central bank or other
Governmental Authority charged with the interpretation or administration
thereof, or (iv) compliance by the Bank (or its Lending Office) or any
corporation controlling the Bank with any Capital Adequacy Regulation, affects
or would affect the amount of capital required or expected to be maintained by
the Bank or any corporation controlling the Bank and (taking into consideration
such Bank's or such corporation's policies with respect to capital adequacy and
such Bank's desired return on capital) determines that the amount of such
capital is increased as a consequence of its Commitment, loans, credits or
obligations under this Agreement; then, in any such case, such Bank shall notify
the Borrower of any such event of which it has knowledge and shall deliver to
the Agent and the Borrower a written statement specifying in reasonable detail
the losses or expense sustained or incurred. The Borrower shall within ten (10)
days following demand therefor, pay the amount sufficient to compensate such
Bank for such increased costs.

3.4 Funding Losses. The Borrower shall reimburse each Bank and hold each
Bank harmless from any loss or expense which the Bank may sustain or incur as a
consequence of:

(a) the failure of the Borrower to make on a timely basis any
payment of principal of any LIBOR Loan;

(b) the failure of the Borrower to borrow, continue or convert a
Loan after the Borrower has given (or is deemed to have given) a Notice of
Borrowing or a Notice of Conversion/Continuation;

(c) the failure of the Borrower to make any prepayment of any Loan
in accordance with any notice delivered under Section 2.6;

(d) the prepayment (including pursuant to Section 2.6 or 3.7) or
other payment (including after acceleration thereof) of any LIBOR Loan on a day
that is not the last day of the relevant Interest Period; or

(e) the automatic conversion under Section 2.4(a) of any LIBOR Loan
to a Prime Rate Loan on a day that is not the last day of the relevant Interest
Period; including any such loss or expense arising from the liquidation or
reemployment of funds obtained by it to maintain its LIBOR Loans or from fees
payable to terminate the deposits from which such funds were obtained.

For purposes of calculating amounts payable by the Borrower to the Banks under
this Section and under subsection 3.3(a), each LIBOR Loan made by a Bank (and
each related reserve, special deposit or similar requirement) shall be
conclusively deemed to have been funded at the LIBOR Rate for such LIBOR Loan by
a
<PAGE>

matching deposit or other borrowing in the interbank eurodollar market for a
comparable amount and for a comparable period, whether or not such LIBOR Loan is
in fact so funded. Each Bank that claims compensation under this section shall
deliver to the Agent and the Borrower a written statement specifying in
reasonable detail any amounts due to the Banks as provided above.

3.5 Inability to Determine Rates. If the Agent determines that for any
reason adequate and reasonable means do not exist for determining the LIBOR Rate
for any requested Interest Period with respect to a proposed LIBOR Loan, or that
the LIBOR Rate for any requested Interest Period with respect to a proposed
LIBOR Loan does not adequately and fairly reflect the cost to the Banks of
funding such Loan, the Agent will promptly so notify the Borrower and each Bank.
Thereafter, the obligation of the Banks to make or maintain LIBOR Loans,
hereunder shall be suspended until the Agent revokes such notice in writing.
Upon receipt of such notice, the Borrower may revoke any Notice of Borrowing or
Notice of Conversion/Continuation then submitted by it. If the Borrower does not
revoke such Notice, the Banks shall make, convert or continue the Loans, as
proposed by the Borrower, in the amount specified in the applicable notice
submitted by the Borrower, but such Loans shall be made, converted or continued
as Prime Rate Loans instead of LIBOR Loans.

3.6 Certificates of Banks. Any Bank claiming reimbursement or
compensation under this Article III shall deliver to the Borrower (with a copy
to the Agent) a certificate setting forth in reasonable detail the amount
payable to the Bank hereunder and such certificate shall be conclusive and
binding on the Borrower in the absence of manifest error.

3.7 Survival. The agreements and obligations of the Borrower in this
Article III shall survive the payment of all other Obligations.

Credit Party's Subsidiaries, showing their respective jurisdictions of
incorporation or organization and, as of the Commitment Closing Date and the

or on notice, could reasonably be expected to result in such a material default

ARTICLE IX
THE AGENT

9.1 Appointment and Authorization. Each Bank hereby irrevocably (subject
to Section 9.9) appoints, designates and authorizes the Agent to take such
action on its behalf under the provisions of this Agreement and each other Loan
Document and to exercise such powers and perform such duties as are expressly
delegated to it by the terms of this Agreement or any other Loan Document,
together with such powers as are reasonably incidental thereto. Notwithstanding
any provision to the contrary contained elsewhere in this Agreement or in any
other Loan Document, the Agent shall not have any duties or responsibilities,
except those expressly set forth herein, nor shall the Agent have or be deemed
to have any fiduciary relationship with any Bank, and no implied covenants,
functions, responsibilities, duties, obligations or liabilities shall be read
into this Agreement or any other Loan Document or otherwise exist against the
Agent.

9.2 Delegation of Duties. The Agent may execute any of
<PAGE>

its duties under this Agreement or any other Loan Document by or through agents,
employees or attorneys-in-fact and shall be entitled to advice of counsel
concerning all matters pertaining to such duties. The Agent shall not be
responsible for the negligence or misconduct of any agent or attorney-in-fact
that it selects with reasonable care.

9.3 Liability of Agent. None of the Agent-Related Persons shall (a) be
liable for any action taken or omitted to be taken by any of them under or in
connection with this Agreement or any other Loan Document or the transactions
contemplated hereby (except for its own gross negligence or willful misconduct),
or (b) be responsible in any manner to any of the Banks for any recital,
statement, representation or warranty made by the Borrower or any Subsidiary or
Affiliate of the Borrower, or any officer thereof, contained in this Agreement
or in any other Loan Document, or in any certificate, report, statement or other
document referred to or provided for in, or received by the Agent under or in
connection with, this Agreement or any other Loan Document, or the validity,
effectiveness, genuineness, enforceability or sufficiency of this Agreement or
any other Loan Document, or for any failure of the Borrower or any other party
to any Loan Document to perform its obligations hereunder or thereunder. No
Agent-Related Person shall be under any obligation to any Bank to ascertain or
to inquire as to the observance or performance of any of the agreements
contained in, or conditions of, this Agreement or any other Loan Document, or to
inspect the properties, books or records of the Borrower or any of the
Borrower's Subsidiaries or Affiliates.
<PAGE>

9.4 Reliance by Agent.

(a) The Agent shall be entitled to rely, and shall be fully
protected in relying, upon any writing, resolution, notice, consent,
certificate, affidavit, letter, telegram, facsimile, telex or telephone message,
statement or other document or conversation believed by it to be genuine and
correct and to have been signed, sent or made by the proper Person or Persons,
and upon advice and statements of legal counsel (including counsel to the
Borrower), independent accountants and other experts selected by the Agent. The
Agent shall be fully justified in failing or refusing to take any action under
this Agreement or any other Loan Document unless it shall first receive such
advice or concurrence of the majority Banks as it deems appropriate and, if it
so requests, it shall first be indemnified to its satisfaction by the Banks
against any and all liability and expense which may be incurred by it by reason
of taking or continuing to take any such action. The Agent shall in all cases be
fully protected in acting, or in refraining from acting, under this Agreement or
any other Loan Document in accordance with a request or consent of the Majority
Banks and such request and any action taken or failure to act pursuant thereto
shall be binding upon all of the Banks.

(b) For purposes of determining compliance with the conditions
specified in Sections 4.1 and 4.2, each Bank that has executed this Agreement
shall be deemed to have consented to, approved or accepted or to be satisfied
with, each document or other matter either sent by the Agent to such Bank for
consent, approval, acceptance or satisfaction, or required thereunder to be
consented to or approved by or acceptable or satisfactory to the Bank.

9.5 Notice of Default. The Agent shall not be deemed to have knowledge
or notice of the occurrence of any Default or Event of Default, except with
respect to defaults in the payment of principal, interest and fees required to
be paid to the Agent for the account of the Banks, unless the Agent shall have
received written notice from a Bank or the Borrower referring to this Agreement,
describing such Default or Event of Default and stating that such notice is a
"notice of default". The Agent will notify the Banks of its receipt of any such
notice. The Agent shall take such action with respect to such Default or Event
of Default as may be requested by the Majority Banks in accordance with Article
VIII; provided, however, that unless and until the Agent has received any such
request, the Agent may (but shall not be obligated to) take such action, or
refrain from taking such action, with respect to such Default or Event of
Default as it shall deem advisable or in the best interest of the Banks.

:\D Credit Decision. Each Bank acknowledges that none of the Agent-
Related Persons has made any representation or warranty to it and that no act by
the Agent hereinafter taken, including
<PAGE>

any review of the affairs of the Borrower and its subsidiaries, shall be deemed
to constitute any representation or warranty by any Agent-Related Person to any
Bank. Each Bank represents to the Agent that it has, independently and without
reliance upon any Agent-Related Person and based on such documents and
information as it has deemed appropriate, made its own appraisal of and
investigation into the business, prospects, operations, property, financial and
other condition and credit worthiness of the Borrower and its Subsidiaries, and
all applicable bank regulatory laws relating to the transactions contemplated
hereby, and made its own decision to enter into this Agreement and to extend
credit to the Borrower hereunder. Each Bank also represents that it will,
independently and without reliance upon any Agent-Related Person and based on
such documents and information as it shall deem appropriate at the time,
continue to make its own credit analysis, appraisals and decisions in taking or
not taking action under this Agreement and the other Loan Documents, and to make
such investigations as it deems necessary to inform itself as to the business,
prospects, operations, property, financial and other condition and credit
worthiness of the Borrower. Except for notices, reports and other documents
expressly herein required to be furnished to the Banks by the Agent, the Agent
shall not have any duty or responsibility to provide any Bank with any credit or
other information concerning the business, prospects, operations, property,
financial and other condition or credit worthiness of the Borrower which may
come into the possession of any of the Agent-Related Persons.

9.7 Indemnification of Agent. Whether or not the transactions
contemplated hereby are consummated, the Banks shall indemnify upon demand the
Agent-Related Persons (to the extent not reimbursed by or on behalf of the
Borrower and without limiting the obligation of the Borrower to do so), pro
rata, from and against any and all Indemnified Liabilities; provided, however,
that no Bank shall be liable for the payment to the Agent-Related Persons of any
portion of such Indemnified Liabilities resulting solely from such Person's
gross negligence or willful misconduct. Without limitation of the foregoing,
each Bank shall reimburse the Agent upon demand for its ratable share of any
costs or out-of-pocket expenses (including Attorney Costs) incurred by the Agent
in connection with the preparation, execution, delivery, administration,
modification, amendment or enforcement (whether through negotiations, legal
proceedings or otherwise) of, or legal advice in respect of rights or
responsibilities under, this Agreement, any other Loan Document, or any document
contemplated by or referred to herein, to the extent that the Agent is not
reimbursed for such expenses by or on-behalf of the Borrower. The undertaking in
this Section 9.7 shall survive the payment of all Obligations hereunder and the
resignation or replacement of the Agent.

9.8 Agent in Individual Capacity. Imperial Bank and its Affiliates may
make loans to, issue letters of credit for the account of, accept deposits from,
acquire equity interests in and
<PAGE>

generally engage in any kind of banking, trust, financial advisory, underwriting
or other business with the Borrower and its Subsidiaries and Affiliates as
though Imperial Bank were not the Agent hereunder and without notice to or
consent of the Banks. The Banks acknowledge that, pursuant to such activities,
Imperial Bank or its Affiliates may receive information regarding the Borrower
or its Affiliates (including information that may be subject to confidentiality
obligations in favor of the Borrower or such Subsidiary) and acknowledge that
the Agent shall be under no obligation to provide such information to them. With
respect to its Loans, Imperial Bank shall have the same rights and powers under
this Agreement as any other Bank and may exercise the same as though it were not
the Agent, and the terms "Bank" and "Banks" include Imperial Bank in its
individual capacity.

9.9 Successor Agent. The Agent may, and at the request of the Majority
Banks shall, resign as Agent upon thirty (30) days, notice to the Banks and the
Borrower. If the Agent resigns under this Agreement, the Majority Banks shall
appoint from among the Banks a successor agent for the Banks. If no successor
agent is appointed prior to the effective date of the resignation of the Agent,
the Agent may appoint, after consulting with the Banks and the Borrower, a
successor agent from among the Banks. Upon the acceptance of its appointment as
successor agent hereunder, such successor agent shall succeed to all the rights,
powers and duties of the retiring Agent and the term "Agent" shall mean such
successor agent and the retiring Agent's appointment, powers and duties as Agent
shall be terminated. After any retiring Agent's resignation hereunder as Agent,
the provisions of this Article IX and Sections 10.4, 10.5 and 10.6 shall inure
to its benefit as to any actions taken or omitted to be taken by it while it was
Agent under this Agreement. If no successor agent has accepted appointment as
Agent by the date which is thirty (30) days following a retiring Agent's notice
of resignation, the retiring Agent's resignation shall nevertheless thereupon
become effective and the Banks shall perform all of the duties of the Agent
hereunder until such time, if any, as the Majority Banks appoint a successor
agent as provided for above.

9.10 Withholding Tax.

(a) If any Bank is a "foreign corporation, partnership or trust"
within the meaning of the Code and such Bank claims exemption from, or a
reduction of, U.S. withholding tax under Sections 1441 or 1442 of the Code, such
Bank agrees with and in favor of the Agent, to deliver to the Agent:

(i) if such Bank claims an exemption from, or a reduction of,
withholding tax under a United States tax treaty, properly completed IRS Forms
1001 and W-8 prior to the Closing Date and prior to the first day of each
calendar year thereafter;

(ii) if such Bank claims that interest paid under this
Agreement is exempt from United States withholding tax
<PAGE>

because it is effectively connected with a United States trade or business of
such Bank, two properly completed and executed copies of IRS Form 4224 prior to
the Closing Date and prior to the first day of each calendar year thereafter and
IRS Form W-9; and

(iii) such other form or forms as may be required under the
Code or other laws of the United States as a condition to exemption from, or
reduction of, United States withholding tax.

Such Bank agrees to promptly notify the Agent of any change in
circumstances which would modify or render invalid any claimed exemption or
reduction.

(b) If any Bank claims exemption from, or reduction of, withholding
tax under a United States tax treaty by providing IRS Form 1001 and such Bank
sells, assigns, grants a participation in, or otherwise transfers all or part of
the Obligations of the Borrower to such Bank, such Bank agrees to notify the
Agent of the percentage amount in which it is no longer the beneficial owner of
Obligations of the Borrower to such Bank. To the extent of such percentage
amount, the Agent will treat such Bank's IRS Form 1001 as no longer valid.

(c) If any Bank claiming exemption from United States withholding
tax by filing IRS Form 4224 with the Agent sells, assigns, grants a
participation in, or otherwise transfers all or part of the Obligations of the
Borrower to such Bank, such Bank agrees to undertake sole responsibility for
complying with the withholding tax requirements imposed by Sections 1441 and
1442 of the Code.

(d) If any Bank is entitled to a reduction in the applicable
withholding tax, the Agent may withhold from any interest payment to such Bank
an amount equivalent to the applicable withholding tax after taking into account
such reduction. If the forms or other documentation required by subsection (a)
of this Section are not delivered to the Agent, then the Agent may withhold from
any interest payment to such Bank not providing such forms or other
documentation an amount equivalent to the applicable withholding tax.

(e) If the IRS or any other Governmental Authority of the United
States or other jurisdiction asserts a claim that the Agent did not properly
withhold tax from amounts paid to or for the account of any Bank (because the
appropriate form was not delivered, was not properly executed, or because such
Bank failed to notify the Agent of a change in circumstances which rendered the
exemption from, or reduction of, withholding tax ineffective, or for any other
reason) such Bank shall indemnify the Agent fully for all amounts aid, directly
or indirectly, by the Agent as tax or otherwise, including penalties and
interest, and including any taxes imposed by any jurisdiction on the amounts
payable to the Agent under this Section, together with all costs
<PAGE>

and expenses (including Attorney Costs). The obligation of the Banks under this
subsection shall survive the payment of all Obligations and the resignation or
replacement of the Agent.

request of the Majority Banks) and the Borrower and acknowledged by the Agent,
and then any such waiver or consent shall be effective only in the specific
instance and for the specific purpose for which given; provided, however, that

Agreement or any other Loan Document, and (ii) the Fee Letter may be amended, or
rights or privileges thereunder waived, in a writing executed by the parties

certain notices by telephone or facsimile is solely for the convenience and at
the request of the Borrower. The Agent and the Banks shall be entitled to rely
on the authority of any Person purporting to be a Person authorized by the
Borrower to give such notice and the Agent and the Banks shall not have any
liability to the Borrower or other Person on account of any action taken or not
taken by the Agent or the Banks in reliance upon such telephonic or facsimile
notice. The obligation of the Borrower to repay the Loans shall not be affected
in any way or to any extent by any failure by the Agent and the Banks to receive
written confirmation of any telephonic or facsimile notice or the receipt by the
Agent and the Banks of a confirmation which is at variance with the terms
understood by the Agent and the Banks to be contained in the telephonic or
facsimile notice.

10.3 No Waiver; Cumulative Remedies. No failure to exercise and no delay
in exercising, on the part of the Agent or any Bank, any right, remedy, power or

partial exercise of any right, remedy, power or privilege hereunder preclude any
other or further exercise thereof or the exercise of any other right, remedy,
power or privilege.

case, whether or not consummated), this Agreement, any Loan Document and any
other documents prepared in connection herewith or therewith, and the
consummation of the transactions contemplated hereby and thereby, including
reasonable Attorney Costs incurred by the Agent with respect thereto; and

obligations, losses, damages, penalties, actions, judgments, suits, costs,
charges, expenses and disbursements (including Attorney Costs) of any kind or
nature whatsoever which may at any time (including at any time following
repayment of the Loans and the termination, resignation or replacement of the

any such Person in any way relating to or arising out of this Agreement or any
document contemplated by or referred to herein, or the transactions contemplated
hereby, or any action taken or omitted by any such Person under or in connection

provided, that the Borrower shall have no obligation hereunder to any
Indemnified Person with respect to Indemnified Liabilities resulting solely from
the gross negligence or willful misconduct of such Indemnified Person. The
agreements in this Section shall survive payment of all other Obligations.

10.6 Payments Set Aside. To the extent that the Borrower makes a payment
to the Agent or the Banks, or the Agent or the Banks exercise their right of
set-off, and such payment or the proceeds of such set-off or any part thereof
are subsequently invalidated, declared to be fraudulent or preferential, set
aside
<PAGE>

or required (including pursuant to any settlement entered into by the Agent or
such Bank in its discretion) to be repaid to a trustee, receiver or any other
party, in connection with any Insolvency Proceeding or otherwise, then (a) to
the extent of such recovery the obligation or part thereof originally intended
to be satisfied shall be revived and continued in full force and effect as if
such payment had not been made or such set-off had not occurred, and (b) each
Bank severally agrees to pay to the Agent upon demand its pro rata share of any
amount so recovered from or repaid by the Agent.

10.7 Successors and Assigns. The provisions of this Agreement shall be
binding upon and inure to the benefit of the parties hereto and their respective
successors and assigns, except that the Borrower may not assign or transfer any
of its rights or obligations under this Agreement without the prior written
consent of the Agent and each Bank.

10.8 Assignments, Participations, etc.

(a) Any Bank may, with the written consents of the Borrower and the
Agent, which consents shall be at the sole discretion of the Borrower and the
Agent, at any time assign and delegate to one or more Eligible Assignees
(provided that (i) no written consent of the Borrower shall be required during
the existence of an Event of Default after the Agent has declared the Commitment
of each Bank to make Loans to be terminated and (ii) no written consent of the
Borrower or the Agent shall be required in connection with any assignment and
delegation by a Bank to an Eligible Assignee that is an Affiliate of such Bank)
(each an "Assignee") all, or any ratable part of all, of the Loans, the Combined
Commitments and the other rights and obligations of such Bank hereunder, in a
minimum amount of $5,000,000; provided, however, that the Borrower and the Agent
may continue to deal solely and directly with such Bank in connection with the
interest so assigned to an Assignee until (i) written notice of such assignment,
together with payment instructions, addresses and related information with
respect to the Assignee, shall have been given to the Borrower and the Agent
such Bank and the Assignee; (ii) such Bank and its Assignee shall have delivered
to the Borrower and the Agent an Assignment and Acceptance in the form of
Exhibit J ("Assignment and Acceptance") together with any Note or Notes subject
to such assignment and (iii) the assignor Bank or Assignee has paid to the Agent
a processing fee in the amount of $2,500.

(b) From and after the date that the Agent notifies the assignor
Bank that it has received (and provided its consent with respect to) an executed
Assignment and Acceptance and payment of the above-referenced processing fee,
(i) the Assignee thereunder shall be a party hereto and, to the extent that
rights and obligations hereunder have been assigned to it pursuant to such
Assignment and Acceptance, shall have the rights and obligations of a Bank under
the Loan Documents, and (ii) the
<PAGE>

assignor Bank shall, to the extent that rights and obligations hereunder and
under the other Loan Documents have been assigned by it pursuant to such
Assignment and Acceptance, relinquish its rights and be released from its
obligations under the Loan Documents.

(c) Within five (5) Business Days after its receipt of notice by the
Agent that it has received an executed Assignment and Acceptance and payment of
the processing fee, (and provided that it consents to such assignment in
accordance with Section 10.8(a)), the Borrower shall execute and deliver to the
Agent, new Notes evidencing such Assignee's assigned Loans and Commitment and,
if the assignor Bank has retained a portion of its Loans and its Commitment,
replacement Notes in the principal amount of the Loans retained by the assignor
Bank (such Notes to be in exchange for, but not in payment of, the Notes held by
such Bank). Immediately upon each Assignee's making its processing fee payment
under the Assignment and Acceptance, this Agreement shall be deemed to be
amended to the extent, but only to the extent, necessary to reflect the addition
of the Assignee and the resulting adjustment of the Combined Commitments arising
therefrom. The Commitment allocated to each Assignee shall reduce such
Commitments of the assigning Bank pro tanto.

(d) Any Bank may at any time sell to one or more commercial banks or
other Persons not Affiliates of the Borrower (a "Participant") participating
interests in any Loans, the Commitment of that Bank and the other interests of
that Bank (the "Originator") hereunder and under the other Loan Documents;
provided, however, that (i) the Originator's obligations under this Agreement
shall remain unchanged, (ii) the Originator shall remain solely responsible for
the performance of such obligations, (iii) the Borrower and the Agent shall
continue to deal solely and directly with the Originator in connection with the
Originator's rights and obligations under this Agreement and the other Loan
Documents, and (iv) no Bank shall transfer or grant any participating interest
under which the Participant has rights to approve any amendment to, or any
consent or waiver with respect to, this Agreement or any other Loan Document,
except to waiver would require unanimous consent of the Banks as described in
the first proviso to Section 10.1. In the case of any such participation, the
Participant shall be entitled to the benefit of Sections 3.1, 3.3 and 10.5 as
though it were also a Bank hereunder, and if amounts outstanding under this
Agreement are due and unpaid, or shall have been declared or shall have become
due and payable upon the occurrence of an Event of Default, each Participant
shall be deemed to have the right of set-off in respect of its participating
interest in amounts owing under this Agreement to the same extent as if the
amount of its participating interest were owing directly to it as a Bank under
this Agreement.

(e) Notwithstanding any other provision in this Agreement, any Bank
may at any time assign all or any portion of
<PAGE>

its rights under and interest in this Agreement and the Note held by it for the
purpose of creating a security interest in favor of any Federal Reserve Bank in
accordance with Regulation A of the FRB or U.S. Treasury Regulation 31 CFR
203.14, and such Federal Reserve Bank may enforce such pledge or security
interest in any manner permitted under applicable law.

10.9 Confidentiality. Each Bank agrees to take and to cause its
Affiliates to take normal and reasonable precautions and exercise due care to
maintain the confidentiality of all information identified as "confidential" or
"secret" by the Borrower and provided to it by the Borrower or any Subsidiary,
or by the Agent on such Company's or Subsidiary's behalf, under this Agreement
or any other Loan Document, and neither it nor any of its Affiliates shall use
any such information other than in connection with or in enforcement of this
Agreement and the other Loan Documents or in connection with other business now
or hereafter existing or contemplated with the Borrower or any Subsidiary;
except to the extent such information (i) was or becomes generally available to
the public other than as a result of disclosure by the Bank, or (ii) was or
becomes available on a non-confidential basis from a source other than the
Borrower, provided that such source is not bound by a legal or contractual
obligation known to the Bank; provided, however, that any Bank may disclose such
information (A) at the request or pursuant to any requirement of any
Governmental Authority to which the Bank is subject or in connection with an
examination of such Bank by any such authority; (B) pursuant to subpoena or
other court process; (C) when required to do so in accordance with the
provisions of any applicable Requirement of Law; (D) to the extent reasonably
required in connection with any litigation or proceeding to which the Agent, any
Bank or their respective Affiliates may be party; (E) after the occurrence of a
Default, to the extent reasonably required in connection with the exercise of
any remedy hereunder or under any other Loan Document; (F) to such Bank's
independent auditors and other professional advisors; (G) to any Participant or
Assignee, actual or potential, provided that such Person agrees in writing to
keep such information confidential to the same extent required of the Banks
hereunder; (H) as to any Ban or its Affiliates, as expressly permitted under the
terms of any other document or agreement regarding confidentiality to which the
Borrower or any Subsidiary is party with such Bank or such Affiliate; and (I) to
its Affiliates; provided, however, that in the event any Bank is requested to
disclose confidential information pursuant to this Section 10.9 (A), (B), (C) or
(D), such Bank shall notify the Borrower promptly, if it may lawfully so do, so
that the Borrower may seek a protective order or other appropriate remedy.

10.10 Set-off. In addition to any rights and remedies of the Banks
provided by law, if an Event of Default exists or the Loans have been
accelerated, each Bank or any Affiliate, which is an Eligible Assignee, thereof
is authorized at any time and from time to time, without prior notice to the
Borrower, any such
<PAGE>

notice being waived by the Borrower 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 by, and other indebtedness at any time
owing by, such Bank to or for the credit or the account of the Borrower against
any and all Obligations owing to such Bank, now or hereafter existing,
irrespective of whether or not the Agent or such Bank shall have made demand
under this Agreement or any Loan Document and although such obligations may be
contingent or unmatured and each such Affiliate is hereby irrevocably authorized
to permit such set-off and appropriation. Each Bank agrees promptly to notify
the Borrower and the Agent after any such set-off and application made by such
Bank; provided, however, that the failure to give such notice shall not affect
the validity of such set-off and application.

10.11 Notification of Addresses, Lending Offices, Etc. Each Bank shall
notify the Agent in writing of any changes in the address to which notices to
the Bank should be directed, of addresses of any Lending Office, of payment
instructions in respect of all payments to be made to it hereunder and of such
other administrative information as the Agent shall reasonably request.

10.12 Counterparts. This Agreement may be executed in any number of
separate counterparts, each of which, when so executed, shall be deemed an
original, and all of said counterparts taken together shall be deemed to
constitute but one and the same instrument.

10.13 Severability. The illegality or unenforceability of any provision of
this Agreement or any instrument or agreement required hereunder shall not in
any way affect or impair the legality or enforceability of the remaining
provisions of this Agreement or any instrument or agreement required hereunder.

10.14 No Third Parties Benefited. This Agreement is made and entered into
for the sole protection and legal benefit of the Borrower, the Banks, the Agent
and the Agent-Related Persons, and successors and assigns and no other Person
shall be a direct or indirect legal beneficiary of, or have any direct or
indirect cause of action or claim in connection with, this Agreement or any of
the other Loan Documents.

10.15 Governing Law and Jurisdiction.

(a) THIS AGREEMENT AND THE NOTES SHALL BE GOVERNED BY, AND CONSTRUED
IN ACCORDANCE WITH, THE LAW OF THE STATE OF CALIFORNIA; PROVIDED THAT THE AGENT
AND THE BANKS SHALL RETAIN ALL RIGHTS ARISING UNDER FEDERAL LAW.

(b) ANY LEGAL ACTION OR PROCEEDING WITH RESPECT TO THIS AGREEMENT OR
ANY OTHER LOAN DOCUMENT MAY BE BROUGHT IN THE COURTS OF THE STATE OF CALIFORNIA
OR OF THE UNITED STATES FOR THE
<PAGE>

SOUTHERN DISTRICT OF CALIFORNIA, AND BY EXECUTION AND DELIVERY OF THIS
AGREEMENT, EACH OF The Borrower, THE AGENT AND THE BANKS CONSENTS, FOR ITSELF
AND IN RESPECT OF ITS PROPERTY, TO THE NON-EXCLUSIVE JURISDICTION OF THOSE
COURTS. EACH OF The Borrower, THE AGENT AND THE BANKS IRREVOCABLY WAIVES ANY
OBJECTION, INCLUDING ANY OBJECTION TO THE LAYING OF VENUE OR BASED ON THE
GROUNDS OF FORUM NON CONVENIENS, WHICH IT MAY NOW OR HEREAFTER HAVE TO THE
BRINGING OF ANY ACTION OR PROCEEDING IN SUCH JURISDICTION IN RESPECT OF THIS
AGREEMENT OR ANY DOCUMENT RELATED HERETO. The Borrower, THE AGENT AND THE BANKS
EACH WAIVE PERSONAL SERVICE OF ANY SUMMONS, COMPLAINT OR OTHER PROCESS, WHICH
MAY BE MADE BY ANY OTHER MEANS PERMITTED BY CALIFORNIA LAW.

10.16 Waiver of Jury Trial. THE CREDIT PARTIES, THE BANKS AND THE AGENT
EACH WAIVE THEIR RESPECTIVE RIGHTS TO A TRIAL BY JURY OF ANY CLAIM OR CAUSE OF
ACTION BASED UPON OR ARISING OUT OF OR RELATED TO THIS AGREEMENT, THE OTHER LOAN
DOCUMENTS, OR THE TRANSACTIONS CONTEMPLATED HEREBY OR THEREBY, IN ANY ACTION,
PROCEEDING OR OTHER LITIGATION OF ANY TYPE BROUGHT BY ANY OF THE PARTIES AGAINST
ANY OTHER PARTY OR ANY AGENT-RELATED PERSON, PARTICIPANT OR ASSIGNEE, WHETHER
WITH RESPECT TO CONTRACT CLAIMS, TORT CLAIMS, OR OTHERWISE. THE CREDIT PARTIES,
THE BANKS AND THE AGENT EACH AGREE THAT ANY SUCH CLAIM OR CAUSE OF ACTION SHALL
BE TRIED BY A COURT TRIAL WITHOUT A JURY. WITHOUT LIMITING THE FOREGOING, THE
PARTIES FURTHER AGREE THAT THEIR RESPECTIVE RIGHT TO A TRIAL BY JURY IS WAIVED
BY OPERATION OF THIS SECTION AS TO ANY ACTION, COUNTERCLAIM OR OTHER PROCEEDING
WHICH SEEKS, IN WHOLE OR IN PART, TO CHALLENGE THE VALIDITY OR ENFORCEABILITY OF
THIS AGREEMENT OR THE OTHER LOAN DOCUMENTS OR ANY PROVISION HEREOF OR THEREOF.
THIS WAIVER SHALL APPLY TO ANY SUBSEQUENT AMENDMENTS, RENEWALS, SUPPLEMENTS OR
MODIFICATIONS TO THIS AGREEMENT AND THE OTHER LOAN DOCUMENTS.

10.17 Entire Agreement. This Agreement, together with the other Loan
Documents, embodies the entire agreement and understanding among the Credit
Parties, the Banks and the Agent, and supersedes all prior or contemporaneous
agreements and understandings of such Persons, verbal or written, relating to
the subject matter hereof and thereof.

10.18 Additional Credit Parties. Upon the execution and delivery by any

"Credit Agreement Supplement"), such Person shall be referred to as an
"Additional Credit Party" and shall be and become a Credit Party, and each
reference in this Agreement to "Credit Party" shall also mean and be a reference
to such Additional Credit Party.

Recitals

A. The Credit Parties, the Banks and the Agent have entered into the
Credit Agreement, dated as of October 10, 1996 (the "Credit Agreement"). Terms
defined in the Credit Agreement and not otherwise defined herein have the same
respective meanings when used herein, and the rules of construction set forth in

B. The Credit Parties, the Banks and the Agent have agreed to amend the
Credit Agreement as hereinafter set forth.

of the Credit Agreement is hereby amended in full to read as follows:

"'Permitted Subordinated Indebtedness' means unsecured Indebtedness of
GMS Holding evidencing seller financing incurred in connection with a

Obligations upon substantially the terms set forth on Exhibit H attached
hereto or upon such other terms as may be satisfactory to the Agent and the
Majority Banks."
<PAGE>

(b) Section 6.12 of the Credit Agreement is hereby amended to read in full
as follows:

any Permitted Acquisition, the Borrower shall have delivered to the Agent

each Bank) the following: (i) at least thirty (30) days prior to the
consummation of such Permitted Acquisition, a brief summary of the
substantive terms thereof and the proposed execution copies of all material
agreements relating to such Permitted Acquisition, including, without
limitation, the acquisition agreement, the management agreement, the
promissory note evidencing Permitted Subordinated Indebtedness and copies
of business plans, financial projections and budgets relating to such
Permitted Acquisition and (ii) an officer's certificate, executed by a

payment or other distribution of assets, properties, cash, rights,
obligations or securities on account of any shares of any class of its

payments to GMS Holding from time to time in an amount not to exceed the
amount required to make the regularly scheduled payment of interest and
principal in respect of any Permitted Subordinated Indebtedness."

(d) Section 7.10 of the Credit Agreement is hereby amended to read in full
as follows:

Acquisition under Section 6.12(a) hereof."

SUPPORT SERVICES AGREEMENT
--------------------------

This Agreement is effective as of March 31, 1997 (the "Effective Date") by and
between Gentle Dental Service Corporation, a Washington corporation ("GDSC"),
and Arena Dental Corporation, a California professional corporation, d/b/a Blue
Oak Dental Group, a Dental Office of Dr. Mark Arena ("Group"), and is made with
reference to the following facts:

1. Group is a California professional corporation able to practice
dentistry in and pursuant to the laws of the State of California.

2. Group delivers dental services to enrolled members of health care plans
and to the public at large. Group's dental services are performed by employed
dentists, and by independent dentists under contract with Group.

3. Group employs dentists, hygienists, nurses and dental assistants only.
Group does not employ and is not desirous of employing administrative and
management staff or any other personnel. Group desires to confine its operations
to the delivery of dental care services free from concern over administrative
matters. Group therefore desires to contract with GDSC to provide business
support services which will enable Group to concentrate on the development and
management of the professional aspects of its dental practice.

4. Group wishes to lease or utilize certain offices and facilities,
equipment, furnishings and supplies which are owned or leased by GDSC and which
are necessary for Group to operate dental clinics.

5. GDSC has special expertise and experience in the operation and marketing
of dental clinics of the type intended to be operated by Group. GDSC has
developed and will continue to develop expertise in the non-dental aspects of
dental facilities where professional dental care has been and will be provided
at low cost because of efficiencies of scale and administrative expertise.

6. Group wishes to engage GDSC to provide Group with certain personnel and
all necessary and appropriate services relating to the development, marketing,
operations, and administration of all non-dental facets of Group's dental
clinics.

NOW, THEREFORE, Group hereby exclusively engages GDSC, and GDSC agrees with
Group, to provide Group the following described facilities, equipment, and
services so as to enable Group to deliver to its patients efficient and cost-
effective dental care, in accordance with the following terms and conditions:

D-3
<PAGE>

1. Facilities.

During the term of this Agreement, and all renewals and extensions hereof, GDSC
shall lease to Group, for Group's use, suitable facilities (hereafter referred
to individually as a "Clinic" and collectively as the "Clinics") for Group to
perform its dental care services. The Clinics will be provided in those
locations designated by Group and shall include those tenant improvements that
are reasonably required by Group. GDSC shall bear all development costs,
acquisition costs, or lease costs associated with the provision of these
facilities and shall assume the economic risk for, and shall otherwise be fully
liable under, all leases or property development agreements. Title to, or
rights of tenancy to, the Clinics shall remain in GDSC, and upon termination of
this Agreement, Group shall immediately surrender the Clinics to GDSC. Group
shall comply with all reasonable requirements concerning use of Clinics as may
be established by GDSC from time to time. Without limiting the generality of
the foregoing, Group shall not take or fail to take any action that would cause
a breach or default under the terms of any lease between GDSC and any third
party with respect to any Clinic.

2. Furniture, Fixtures and Equipment.

During the term of this Agreement, and all renewals and extensions hereof, GDSC
shall lease to Group, at each Clinic at which Group performs its dental care
services, the dental equipment, office equipment, furniture, fixtures,
furnishings and leasehold improvements reasonably necessary for Group to perform
its dental care services.

The use by Group of such furniture, fixtures, furnishings, and equipment shall
be subject to the following conditions:

1. Title to all such furniture fixtures, furnishings, and equipment
shall remain in GDSC and upon termination of this Agreement, Group
shall immediately return and surrender all such furniture, fixtures,
furnishings, and equipment to GDSC in as good condition as when
received, normal wear and tear excepted. Group expressly agrees to
execute any appropriate UCC-1 Financing Statement and UCC-1 Fixture
Filings, if so requested in writing by GDSC.

2. GDSC shall be fully and entirely responsible for all repairs and
maintenance of all such furniture, fixtures, furnishings, and
equipment; provided, however, that Group agrees that it will use its
best efforts to prevent damage, excessive wear, and breakdown of all
such furniture, fixtures, furnishings, and equipment and shall advise
GDSC of any and all needed repairs and equipment failures.

3. Administrative Services.

D-4
<PAGE>

During the term of this Agreement, and all renewals and extensions hereof, Group
hereby engages GDSC as the exclusive provider of all non-dental functions and
non-dentist services relating to the operation of the Clinics; and GDSC agrees
to furnish to Group all of the non-dental functions and services that may be
reasonably needed by Group in connection with the operation of the Clinics.
Such non-dental services and functions shall include the following:

1. Bookkeeping and Accounts.

GDSC shall provide all bookkeeping and accounting services reasonably
necessary or appropriate to support the Clinics, including, without
limitation, maintenance, custody and supervision of all of business records,
papers, documents, ledgers, journals and reports (the "Books and Records"),
the preparation, distribution and recording of all remittances by Group for
accounts payable or payroll, and the preparation, distribution and recording
of all bills and statements for professional services rendered by Group,
including the billing and completion of reports and forms required by
insurance companies, governmental agencies or other third-party payors (such
records, papers, documents, ledgers, journals and reports shall not be
deemed to include patient records and other records, reports and documents
which relate to patient treatment by Group's dentists). The Books and
Records at all times shall be materially correct and complete and contain
correct and timely entries made with respect to transactions entered into
pursuant hereto in accordance with generally accepted accounting principles
("GAAP") as in effect at such time.

It is understood, however, that all such business records, papers and
documents are the sole property of Group, shall be available for inspection
by Group at all times, and shall be delivered to Group upon termination of
this Agreement. Group shall provide GDSC with a complete copy of all such
documents, records, and papers at Group's expense upon termination of this
Agreement.

2. Contract Administration.

GDSC shall provide Group with administrative services reasonably necessary
to enable Group to perform on a timely basis all non-dental aspects of
prepaid dental care contracts and other dental care contracts of Group. Such
services shall include the preparation and analysis of reports to enable
Group to provide dentist staffing and supervision at the Clinics for the
rendering of efficient and appropriate dental care to patients.

3. Non-dentist Personnel.

GDSC shall employ and provide such support personnel to Group as may be
reasonably necessary to enable Group to perform its dental services at the
Clinics subject to the following:

D-5
<PAGE>

1. GDSC shall provide all personnel at the Clinics excluding dentists,
dental assistants, nurses and dental hygienists. This shall include,
but is not limited to, the provision of all receptionists,
secretaries, clerks, purchasing and marketing personnel, janitorial
and maintenance personnel, and nondentist supervisory personnel as
may be deemed reasonably necessary by GDSC for the proper and
efficient operation of the Clinics;

2. GDSC shall be responsible for hiring and firing all such support
personnel, and shall determine compensation for all such personnel,
including the determination of the salaries, fringe benefits,
bonuses, health and disability insurance, workers' compensation
insurance, and any other benefits that each such employee shall
receive; and

3. GDSC shall manage and supervise all licensed support personnel
employed on behalf of Group at the Clinics, including, but not
limited to all nurses, dental assistants, and dental hygienists,
regarding those aspects of their employment that do not involve
performance under the scope of their licensure; provided, however
that Group shall manage and supervise all activities of such
licensed support personnel performed under the scope of their
licensure. Group shall be solely responsible for management and
supervision of dentists.

Provision of dental services during extended hours of operation, generally
including at least 60 hours per week during which Clinics are open to the
public, is a central feature of Group's operations and competitive strategy.
GDSC agrees to provide staffing as reasonably required to permit operation
of the Clinics during extended hours of operation.

4. Supplies.

GDSC shall acquire and supply to Group all dental and other supplies of
every kind, name or nature, which may reasonably be required by Group for
the operation of the Clinics, provided that Group shall be responsible for
ordering, receiving and handling all pharmaceuticals and related supplies
for which state or federal certification, registration or licensure is
required.

5. Security and Maintenance.

GDSC shall provide to Group all services and personnel reasonably necessary
to provide Group with proper security, maintenance, and cleanliness of the
Clinics and the furniture, fixtures, equipment, and leasehold improvements
located thereat. Additionally, GDSC shall furnish to or obtain for Group all
laundry, linens, uniforms, printing, stationery,

D-6
<PAGE>

forms, telephone service, postage, duplication services, and any and all
other supplies and services of a similar nature which are reasonably
necessary in connection with the day-to-day operation of the Clinics.

6. Dentist Recruiting.

GDSC shall assist Group in recruiting and screening prospective dentists and
licensed support personnel as employees or contractors for Group. Group
shall be solely responsible for hiring, supervision, training, evaluation
and termination of dentists. Group shall be responsible for hiring and
termination of licensed support personnel and for all supervision, training
and evaluation of such personnel with respect to all activities performed
under the scope of their licensure.

7. Insurance.

GDSC shall use all reasonable efforts to obtain for Group and maintain in
full force and effect during the term of this Agreement, and all extensions
and renewals thereof, comprehensive commercial liability and property
insurance (with Group as a named insured) which GDSC reasonably determines
to be appropriate to protect against loss in the nature of fire, other
catastrophe, theft, business interruption, public liability, and non-dental
negligence, with minimum coverage limits of $1,000,000 per occurrence. GDSC
shall assist Group in obtaining dental malpractice insurance for Group and
its dentist employees.

8. Billing and Collection

In order to relieve Group of the administrative burden of handling the
billing and collection of sums due for the delivery of dental services, GDSC
shall be responsible, on behalf of and for Group and any contract dentists
or independent dentists or other organizations practicing dentistry for or
on behalf of Group, on their respective billheads as their agent, for
billing and collecting the charges with respect to all dental and other
services provided at the Clinics. Group hereby appoints GDSC as its true and
lawful agent for the term of this Agreement in Group's name and on its
behalf (i) to bill for services rendered by Group; (ii) to collect accounts
receivable generated by such billings; (iii) to receive payments for
services rendered by Group; and (iv) to deposit in the Accounts described in
subparagraph i. below any amounts received in payment of services rendered
by Group. Group agrees that it will keep and provide to GDSC all documents,
opinions, diagnosis, recommendations, and other evidence and records
necessary for the purpose of supporting the fees charged for all dental and
other services from time to time.

It is expressly understood that the extent to which GDSC will endeavor to
collect such charges, the methods of collecting, the settling of disputes
with respect to charges and the writing off of charges that may be or appear
to be uncollectible shall at all times be within

D-7
<PAGE>

the sole discretion of GDSC (but subject to all applicable governmental
regulations and the terms and conditions of applicable provider agreements)
and that GDSC does not guarantee the extent to which any charges billed will
be collected. Group may, on its own, continue collection efforts with
respect to any accounts which GDSC has determined to be uncollectible.

Group or its duly authorized agent shall have the right at all reasonable
times and upon the giving of reasonable notice to examine, inspect and copy
the records of GDSC pertaining to such fees, charges, billings, and
collections.

9. Bank Accounts and Disbursements.

During the term of this Agreement, GDSC shall establish and maintain bank
accounts in the name of Group (the "Accounts") for the deposit of all sums
received by Group from the provision of dental services or otherwise. Group
hereby authorizes GDSC to deposit checks and other funds received by Group
into the Accounts. GDSC and its authorized officers shall at all times
during the term of this Agreement have authority to sign checks and stop
payment on checks drawn on the Accounts. GDSC is hereby expressly authorized
to, and shall, disburse from the Accounts sums for the payment of Group's
expenses as described in Section 4, GDSC's compensation as described in
Section 7, and all other costs, expenses and disbursements which are
required or authorized by this Agreement.

10. Market Research and Activities.

GDSC shall conduct market research with respect to rates, charges,
competitive conditions, competition and business opportunities for GDSC and
Group. GDSC shall compile such information and provide marketing reports and
analyses to Group. Subject to prior approval of Group, GDSC shall develop
and distribute marketing materials (such as yellow page advertisements) that
communicate a philosophy of high quality customer-oriented dental care, as
GDSC determines to be appropriate. GDSC shall assist Group in improving
patient satisfaction in order to maintain existing patients, expand services
to existing patients and generate new referrals from existing patients. In
providing such marketing services, GDSC will act solely in its capacity as
administrator for Group. At no time shall GDSC hold itself out as providing
dental services on behalf of Group. All such marketing services shall be
conducted in accordance with the laws, rules, regulations and guidelines of
all applicable governmental and quasi-governmental agencies.

11. Contract Negotiations.

GDSC shall negotiate on Group's behalf contracts with health plans,
preferred provider organizations, other group plans, independent provider

final approval and authority with respect to such contracts, and Group shall
have the sole and absolute right not to enter into any such contracts.

12. Management and Planning Reports.

GDSC shall supply Group on a regular, periodic basis such internal reports
as may be necessary or appropriate for the parties to assist each other in
evaluating the non-dental aspects of the performance and productivity of
their respective employees and contractors as well as in evaluating the
efficiency and effectiveness of the rendition of their respective management
and other nonprofessional services. GDSC shall provide Group with data and
reports for Group's exclusive use in conducting Group's dental practice,
evaluating the performance of Group's dentists and for other purposes
related to maintaining and improving patient care quality and improving the
efficiency of Group's dentists.

4. Duties of Group

1. Conduct of Dental Practice.

Group shall be solely and exclusively in control of all aspects of the
practice of dentistry and the delivery of dental services at the Clinics.
The rendition of all dental professional services, including, but not
limited to, diagnosis, treatment, surgery, therapy and the prescription of
medicine and drugs, and the supervision of preparation of dental reports
shall be the responsibility of Group. Group shall have the sole right and
authority to hire, employ, train, supervise, terminate, and compensate all
of its dentist-contractors and dentist-employees, dental assistants, and
dental hygienists.

GDSC shall have no authority whatsoever with respect to such activities, and
shall have no authority with respect to the establishment of fees or charges
for the rendition of such services.

2. Staffing of Clinics

Group agrees to assign a dentist to act as Clinical Director at each Clinic.
Group will assure that each Clinic is adequately staffed during operating
hours, including extended hours of operation, with such dental personnel as
may be necessary to efficiently carry out the practice of dentistry at each
Clinic.

3. Professional Personnel.

Group shall ensure that dentists and other licensed personnel employed or
contracted by Group are properly licensed and trained. Group shall be
responsible for monitoring quality of care, responding to any patient
complaints concerning dental services and undertaking appropriate quality
improvement activities. Group shall arrange for continuing education

D-9
<PAGE>

for licensed personnel in accordance with all legal requirements and good
professional practice.

4. Wages, etc.

Group shall be solely responsible for payment of all wages, salaries,
bonuses and benefits of its employed licensed personnel, including all
payroll taxes, vacation and sick pay, insurance and pension or profit
sharing contributions.

Group shall be solely responsible for payment of all amounts due to
contracted licensed personnel under service contracts with Group. GDSC shall
provide payroll processing and accounts payable services as provided in this
Agreement.

5. Professional Expenses.

Group shall pay all professional dues and license fees, continuing education
costs and similar costs incurred by Group's employees. Group shall pay the
cost of all professional liability insurance maintained pursuant to
subsection 4.f.

6. Professional Liability Insurance.

Group shall continuously maintain throughout the term of this Agreement
professional liability (malpractice) insurance for all licensed personnel of
Group in amounts not less than $1,000,000 per incident and $3,000,000 annual
limit for each dentist and dental hygienist employed by Group. Group shall
purchase extended reporting endorsements ("tail coverage") for personnel
leaving employment with Group, or on change in insurance policies, if such
coverage is available at reasonable rates. Group shall require all
contracted dentists and dental hygienists to maintain similar coverages. The
minimum amounts of insurance required by this Agreement shall be increased
as necessary to reflect current standards for dental malpractice coverage.

5. Relationship of Parties.

The President of Group, or another licensed dentist designated by Group, shall
act as Group's liaison to GDSC. Group shall delegate to such person all
authority to make decisions on behalf of Group concerning day-to-day operations.
The person so designated shall consult with GDSC on operational matters as
requested. If approval by directors or shareholders of Group is required or
requested for any action recommended or referred for approval by GDSC, Group
shall take all reasonable steps to promptly refer the matter for decision to
Group's directors or shareholders, as appropriate.

Group designates GDSC's President, or his representative, as Group's Attorney-
In-Fact, with full right and authority, but in each instance at Group's express
direction, to execute contracts on

D-10
<PAGE>

behalf of Group, including, but not limited to health plan agreements and
employment agreements. As Attorney-In-Fact, GDSC's President shall have the
right to authorize expenditures on behalf of Group for all activities related to
its business.

Notwithstanding the above, this Agreement is a business support services
agreement only. GDSC shall have no control over Group, and Group shall retain
the sole and exclusive authority over all aspects of its dental practice
including, but not limited to, the authority to approve the locations of
Clinics, the types of improvements, furnishings, equipment and supplies to be
utilized, the manner of practice of dentistry or related ancillary services,
marketing approaches or advertisements, choice of dental personnel, treatment
decisions, assignment of patients to professionals, the content of dental
evaluation reports, fees charged, programs and services engaged in, and any
aspects of dental practice not listed that are the sole prerogative of a duly
licensed dentist under applicable state law.

In the performance of this Agreement, it is mutually understood and agreed that
all dentists, dental hygienists and dental assistants practicing at any of the
Clinics are at all times acting and performing as employees of Group or as
contractors with Group ("Group's Personnel") and not as employees or agents of
GDSC. GDSC shall neither have nor exercise any control or direction over the
methods by which Group or Group's Personnel shall practice dentistry.

Group and Group's Personnel shall have no claim under this Agreement or
otherwise against GDSC for workers' compensation, unemployment compensation,
sick leave, vacation pay, retirement benefits, Social Security benefits, or any
other employee benefits, all of which shall be the sole responsibility of Group.
Since Group's Personnel are not employees of GDSC, GDSC shall not withhold on
behalf of Group's Personnel pursuant to this Agreement any sums for income tax,
unemployment insurance, Social Security, or otherwise pursuant to any law or
requirement of any governmental agency, and all such withholding, if any is
required, shall be the sole responsibility of Group. Group shall indemnify and
hold harmless GDSC from any and all loss or liability arising with respect to
any of the foregoing benefits or withholding requirements.

Group shall require all dentists in its employ to execute non-competition
agreements in a form satisfactory to GDSC that prohibit such dentists from
providing dental services within five miles of a location at which they
provided dental services for Group for a period of two years after termination
of employment with Group. Group shall take all reasonable steps to enforce such
agreements in the event of any breach thereof.

All patient records, reports and information obtained, generated or encountered
relating to Clinics shall at all times be the property of Group and so long as
in the possession, use or control of either party, shall be kept in the
strictest confidence by both parties. GDSC shall instruct all of its personnel
to keep confidential any such information, as well as any financial,
statistical, personnel, and patient information obtained or encountered relating
to Group or to Group's operations.

D-11
<PAGE>

Group shall not solicit, employ or contract with any employee of GDSC or any
entity or person that employs or contracts with any employee of GDSC, for a
period of two years after any such employee ceases to be employed by GDSC.
Should Group breach this specific provision, Group acknowledges that the damages
to GDSC would be difficult to ascertain, and shall as reasonable compensation
and liquidated damages promptly pay GDSC the sum of $40,000.

6. Confidential Information and Trade Secrets.

Group recognizes that due to the nature of this Agreement, Group will have
access to information of a proprietary nature owned by GDSC including, but not
limited to, any and all computer programs, and any and all operating manuals or
similar materials which constitute the non-dental systems, policies, procedures,
and methods of doing business developed for the operation of facilities managed
by GDSC. Consequently, Group acknowledges and agrees that GDSC has a
proprietary interest in all such information and that all such information
constitutes confidential and proprietary information and trade secrets of GDSC.
Group hereby waives any and all right, title and interest in and to such trade
secrets and confidential information and agrees to return all copies of such
trade secrets and confidential information related thereto to GDSC, at Group's
expense, upon the termination of this Agreement.

Group further acknowledges and agrees that GDSC is entitled to prevent its
competitors from obtaining and utilizing its trade secrets and confidential
information. Therefore, Group agrees to hold GDSC's trade secrets and
confidential information in strictest confidence and not to disclose them or
allow them to be disclosed, directly or indirectly, to any person or entity
other than those persons or entities who are employed by or affiliated with GDSC
or Group, without the prior written consent of GDSC. Group shall not, either
during the term of this Agreement, or at any time after the expiration or sooner
termination of this Agreement, disclose to anyone other than persons or entities
who are employed by or affiliated with GDSC or Group any confidential or
proprietary information or trade secret information obtained by Group from GDSC,
except as otherwise required by law. Group agrees to require each independent
contractor and employee of the Group, and any such persons or entities to whom
such information is disclosed for the purpose of performance of GDSC's or
Group's obligations under this Agreement, to execute a "Confidentiality
Agreement" regarding such information in such form as from time-to-time may be
approved by Group and GDSC.

Group acknowledges and agrees that a breach of this Section 6 will result in
irreparable harm to GDSC which cannot be reasonably or adequately compensated in
damages, and therefore GDSC shall be entitled to injunctive and/or equitable
relief to prevent a breach and to secure enforcement thereof, in addition to any
other relief or award to which GDSC may be entitled.

7. GDSC's Compensation.

For its services hereunder, including lease of all facilities, furniture,
fixtures and equipment at the Clinics, provision of all employees of GDSC who
perform services at or for the Clinics, and

D-12
<PAGE>

provision of insurance, supplies and management support services contemplated
hereunder, Group shall pay GDSC the following service fee:

during the remainder of 1997, [*]% of Net Revenues,
during 1998, [*]% of Net Revenues,
during 1999 and for the remainder of the term of this Agreement and
any renewal term, [*]% of Net Revenues.

The service fee can be adjusted by mutual agreement from time to time. Monthly
accruals of service fees shall be made based on estimated Net Revenues year-to-
date; final adjustment of the fee shall be made based on the final Net Revenue
for the calendar year determined after the closing of Group's books for the
year. GDSC shall be entitled to collect the accrued service fees from Group by
deducting from Group's cash collections on a daily basis that percentage of such
collections equal to the current service fee percentage according to the
schedule set forth above. Such deductions shall be made from funds collected in
the Accounts as provided in subsection 4.i. above.

To secure payment of all amounts due to GDSC hereunder, Group hereby grants GDSC
a security interest in all of Group's accounts receivable and proceeds
therefrom. Group will execute a Security Agreement in the form attached hereto
as Annex I and such financing statements and other documents as GDSC may
reasonably request from time to time to evidence and perfect such security
interest.

8. Definitions.

Any accounting term used in this Agreement shall have, unless otherwise
specifically provided herein, the meaning customarily given in accordance with
generally accepted accounting principles ("GAAP"), and all financial
computations hereunder shall be computed unless otherwise specifically provided
herein, in accordance with GAAP as consistently applied and using the same
method of valuation as used in the preparation of GDSC's financial statements.

"Gross Revenues" means all billings by Group for services rendered during the
term of this Agreement, billed at Group's standard rates. For purposes of
capitated service contracts, "Gross Revenues" means the amount of revenue
received under the service contract for services rendered during the term of
this Agreement.

"Net Revenues" means all Gross Revenues net of allowances for contractual
discounts and bad debt. Bad debt allowances shall be determined in accordance
with GAAP. Contractual discount allowances shall be based on reasonable

such default so long as (i) the Guarantor or the Company (as the case may be)
diligently commences and pursues such cure and (ii) the extension of such cure
periods does not have a material adverse effect on Holder) or (B) that any of
the representations or warranties of the Guarantor or the Company made in
Guaranty or Security Agreement proves to have been false or misleading in any
material respect when made, unless the Guarantor or company, as the case may be,
remedies the same to the reasonable satisfaction of the Holder within thirty
(30) days of written notice of the same from the Holder (or such longer period
of time as may be reasonably necessary to cure the same so long as (i) the
Guarantor or the Company, as the case may be, diligently commences and pursues
such cure and (ii) the extension of such cure period does not have a material
adverse effect on Holder).

The Company acknowledges and agrees that its obligations under this Note
are absolute, unconditional and irrevocable, and the company shall have no
offset or other similar rights under this Note in any circumstances, including,
without limitation, an early termination of the Management Agreement for any
reason, except that the Company may offset against amounts coming due hereunder
------ ----
any amounts which are finally determined to be due and payable (and which are
not timely paid) by Holder to the Company pursuant to Section 8.1 of the Asset
Purchase Agreement, in accordance with the provisions of Article 8 of the Asset
Purchase Agreement.

<PAGE>

Notwithstanding the preceding paragraph, in the event that the Company
asserts a bona fide claim pursuant to Section 8.1 of the Asset Purchase
Agreement (a "Claim"), then, pending the final determination of the Company's
rights under Article 8 of the Asset Purchase Agreement in respect of such Claim,
the Company shall be entitled to withhold from amounts coming due under this
Note an aggregate amount up to the amount of any such Claim; provided that as a
condition to such withholding, the Company shall establish a joint bank account
(the "Separate Account") in the name of the Company and the Holder (which
account shall require signatures of representatives of both the Holder and the
Company for any withdrawals) and shall deposit all such withheld amounts
("Disputed Funds") into such account. The Disputed Funds shall be held in the
Separate Account until the Claim is finally settled. Holder shall take all
reasonable steps requested by the Company to facilitate the creation of the
Separate Account and the depositing therein of the Disputed Funds.

In the event the Company and/or its affiliates desire to incur an aggregate
principal amount of Senior Liabilities (as defined in the Intercreditor
Agreement) at any time in an amount exceeding Twelve Million Dollars
($12,000,000) (such aggregate desired amount, the "Desired Senior Liabilities
Amount"), then, as a condition thereto, the Company shall first provide written
notice (an "Increase Notice") to the Holder (along with financial statements of
the Company certified by an officer of the Company) evidencing in reasonable
detail that the Guarantor's Leverage Ratio (as defined below) for each of its
two (2) fiscal quarters immediately preceding the date of such notice was not
greater than 3.75 to 1. Upon receipt of an Increase Notice from Company, Holder
shall within five (5) business days provide a written notice to Company, with a
copy to the Agent (as defined in the Intercreditor Agreement) either (i)
confirming Holder's consent and agreement to the information contained in
Company's Increase Notice or (ii) explaining in reasonable detail any
disagreement with Company's Increase Notice. If Holder fails to so respond to an
Increase Notice within such five (5) business days, Holder shall be deemed to
have agreed to the increase in Senior Liabilities up to the Desired Senior
Liabilities Amount as described in the Increase Notice. For purposes hereof, the
Guarantor's Leverage Ratio shall be determined by taking a fraction (i) the
numerator of which equals the Desired Senior Liabilities Amount and (ii) the
denominator of which equals the earnings of the Guarantor and its subsidiaries
taken on a consolidated basis before accounting for interest, taxes,
depreciation and amortization (EBIDTA), determined on an annualized basis and
otherwise in accordance with GAAP. The Company shall be deemed to have committed
an Event of Default hereunder if the Company causes or permits the Senior
Liabilities to be so increased without first providing an Increase Notice and
obtaining prior approval of Holder as required hereunder.

For so long as amounts remain outstanding under this Note the Company will
provide the Holder with (i) unaudited quarterly financial statements of the
Guarantor within 60 days following the close of each of the Guarantor's fiscal
quarters and (ii) audited financial statements of the Guarantor within 120 days
following the close of the Guarantor's fiscal year.

At the end of each quarterly period during the term of this Note, an
appropriate officer of the Company shall send written notice to the Holder
certifying that no Event of Default exists under either this Note or the
outstanding Senior Indebtedness, unless such default exists, in which case the
Company shall follow the default notice provisions in this Note and the
Intercreditor Agreement.

<PAGE>

The Company reserves the right, subject to the prior written consent of
Imperial Bank, to prepay this Note, in whole or in part at any time or from time
to time without penalty or premium. Any prepayments shall be credited first to
accrued but unpaid interest and then to the latest maturity or maturities of
principal remaining unpaid. In the event of prepayment in part, a new note shall
be issued representing the unpaid amount.

Any portion of the principal amount of this Note which is paid before its
due date (whether by optional prepayment, acceleration or otherwise) shall be
discounted by computing the present value, as of the date of actual payment, and
using a discount rate of 8% per annum, compounded monthly, and based on the
maturity date of the amount prepaid.

If any payment required hereunder is not made when due, and if action is
instituted on this Note, the Company agrees to pay the Holder any and all costs
and expenses incurred in connection with the enforcement or collection of this
Note, including, without limitation, all reasonable attorneys' fees and
disbursements and court costs. Additionally, any portion of the principal amount
hereof not paid on or before the date due (whether at maturity, upon
acceleration or otherwise) shall accrue interest following the date due at the
lesser of (i) the "reference rate" announced from time to time by Bank of
America NT&SA plus four percent (4%) or (ii) the maximum rate permitted by law,
which interest shall be payable on demand.

Any notice required or permitted hereunder shall be given in the manner
provided in the Intercreditor Agreement.

This Note may be assigned by Holder at any time.

GUARANTY
--------

THIS AGREEMENT IS EXPRESSLY SUBJECT TO AND CONDITIONED UPON THE TERMS,
PROVISIONS AND CONDITIONS SET FORTH IN THAT CERTAIN INTERCREDITOR AGREEMENT
DATED AS OF THE DATE HEREOF. ANY TRANSFEREE OF THIS AGREEMENT SHALL BE BOUND BY
ALL OF THE TERMS OF SUCH INTERCREDITOR AGREEMENT.

This Guaranty, dated as of July 24, 1997, is made by GMS DENTAL GROUP, INC.,
a Delaware corporation ("GMS Holding" or the "Guarantor") in favor of FREMONT
----------- ---------
DENTAL GROUP, a California general partnership ("Fremont"), in its capacity
-------
as beneficiary of this Guaranty (together with its successors and permitted
assigns, including, without limitation, the successors and assigns referred to
in Section 5.6 hereof, individually and collectively, the "Beneficiary").
-----------

RECITALS

A. GMS Dental Group Management, Inc., a Delaware corporation (the "Debtor"),
------
is a wholly-owned subsidiary of GMS Holding.

B. The Debtor and GMS Holding are entering into that certain Asset Purchase
Agreement, dated as of the date hereof (the "Asset Purchase Agreement"), with
------------------------
Fremont pursuant to which Debtor is purchasing from Fremont, and Fremont is
selling, transferring, assigning, conveying and delivering to Debtor, all of
Fremont's right, title and interest in and to the Purchased Assets. Capitalized
terms defined in the Asset Purchase Agreement and not otherwise defined herein
have the same respective meanings when used herein.

C. In order to induce Fremont to enter into, and as conditions precedent to
the consummation of, the Asset Purchase Agreement and the transactions
contemplated thereunder, the Guarantor is executing and delivering this Guaranty
to the Beneficiary. The Guarantor acknowledges that it and the Debtor constitute
a common enterprise and that the Guarantor will benefit, directly and
indirectly, from the consummation of the transactions contemplated under the
Asset Purchase Agreement, the Note, the Earn-Out Agreement, the Security
Agreement and this Guaranty (collectively, the "Operative Documents").
-------------------
Accordingly, the Guarantor hereby agrees with the Beneficiary for its benefit as
set forth below.

ARTICLE I

GUARANTY

1.1 Guaranteed Obligations. The Guarantor hereby absolutely, irrevocably and
----------------------
unconditionally guarantees the punctual payment when due, whether at stated
maturity, by acceleration or otherwise, of all obligations of the Debtor now or
hereafter existing under, in respect of or in connection with each Operative
Document, including, without limitation, any

<PAGE>

extensions, modifications, substitutions, amendments and renewals thereof,
whether for principal, interest, fees, expenses, indemnification or otherwise
(all of such obligations hereby guaranteed by any Guarantor herein collectively
called the "Guaranteed Obligations").
----------------------

1.2 Expenses. The Guarantor agrees to pay, in addition, any and all
--------
expenses (including, without limitation, reasonable counsel fees and expenses)
incurred by the Beneficiary in enforcing any rights under this Guaranty with
respect to the Guarantor.

1.3 Guaranty of Payment. Without limiting the generality of the foregoing,
-------------------
this Guaranty guarantees, to the extent provided herein, the payment of all
amounts that constitute part of the Guaranteed Obligations and would be owed by
the Debtor to the Beneficiary under any Operative Document but for the fact that
they are unenforceable or not allowable due to the existence of a bankruptcy,
reorganization or similar proceeding involving the Debtor. This is a guaranty of
payment and not of collection.

1.4 Obligations Several. The obligations of the Guarantor under this
-------------------
Guaranty are several and independent of the Guaranteed Obligations, and a
separate action or actions may be brought and prosecuted against the Guarantor
to enforce this Guaranty, irrespective of whether any action is brought against
the Debtor or whether the Debtor is joined in any such action or actions.

ARTICLE II

GUARANTY ABSOLUTE

The Guarantor guarantees that the Guaranteed Obligations will be paid
strictly in accordance with the terms of the Operative Documents, regardless of
any requirement of law now or hereafter in effect in any jurisdiction affecting
any of such terms or the rights of the Beneficiary with respect thereto. The
liability of the Guarantor under this Guaranty shall be absolute, irrevocable,
and unconditional, irrespective of the following:

(a) any lack of validity or enforceability of, or any release or
discharge of the Debtor from liability under any Operative Document;

(b) any change in the time, manner or place of payment of, or in any
other term of, any or all of the Guaranteed Obligations or any other amendment
or waiver of, or any consent to departure from, any Operative Document;

(c) any taking, subordination, compromise, exchange, release,
nonperfection or liquidation of any collateral, or any release, amendment or
waiver of, or consent to departure from, any other guaranty, for any or all of
the Guaranteed Obligations;

(d) any manner of application of collateral, or proceeds thereof, to
any or all of the Guaranteed Obligations; or any manner of sale or other
disposition of any collateral or any other assets of the Debtor or the
Guarantor;

-2-
<PAGE>

(e) any change, restructuring or termination of the corporate structure or
existence of the Debtor, or any corresponding restructure of the Guaranteed
Obligations, or any other restructure of the Guaranteed Obligations or any
portion thereof;

(f) any exercise or nonexercise by the Beneficiary of any right or
privilege under this Guaranty or any of the other Operative Documents;

(g) any bankruptcy, insolvency, reorganization, composition, adjustment,
dissolution, liquidation or other like proceeding relating to the Guarantor,
the Debtor or any other guarantor of the Guaranteed Obligations, or any action
taken with respect to this Guaranty by any trustee, receiver or court in any
such proceeding, whether or not the Guarantor has had notice or knowledge of any
of the foregoing;

(h) any assignment or other transfer, in whole or in part, of this
Guaranty or any of the other Operative Documents (including, without limitation,
as referred to in Section 5.6 hereof);

(i) any acceptance of partial performance of the Guaranteed Obligations;
or

(j) any other circumstance (including, without limitation, any statute of
limitations) that might otherwise constitute a defense available to, or a
discharge of, the Debtor or any guarantor of the Guaranteed Obligations.

This Guaranty shall continue to be effective or be reinstated, as the case may
be, if at any time any payment of any of the Guaranteed Obligations is rescinded
or must otherwise be returned by the Beneficiary or other Person (as hereinafter
defined) upon the insolvency, bankruptcy or reorganization of the Debtor, the
Guarantor or otherwise, all as though such payment had not been made. The term
"Person" shall mean any individual, partnership, corporation, trust,
------
unincorporated association, limited liability company or other entity; and,
collectively, "Persons".
-------

ARTICLE III

WAIVERS

3.1 Waivers. The Guarantor irrevocably waives the following, to the
extent permitted by applicable law:

(a) promptness, diligence, notice of acceptance and any other notice
with respect to any of the Guaranteed Obligations or this Guaranty;

(b) any requirement that the Beneficiary or any other Person protect,
secure, perfect or insure any Lien (as hereinafter defined) or any property
subject thereto or exhaust any right or take any action against the Debtor, any
other Person or any collateral;

(c) any defense based upon an election of remedies by the Beneficiary
that in any manner impairs, reduces, releases or otherwise adversely affects
the Guarantor's subrogation,

-3-
<PAGE>

contribution or reimbursement rights or other rights to proceed against the
Debtor, any other Person or any collateral, including, without limitation, any
election to proceed by judicial or nonjudicial foreclosure of any Lien, whether
on real property or personal property, or by deed in lieu thereof, whether or
not every aspect of any foreclosure sale is commercially reasonable (including,
without limitation, any defense, right or benefit based on or arising out of any
of California Code of Civil Procedure Sections 580a, 580b, 580d and 726);

(d) any duty on the part of the Beneficiary to disclose to the
Guarantor any matter, fact or thing relating to the business, operation or
condition (including, without limitation, the financial condition) of the Debtor
or its assets now known or hereafter known by the Beneficiary; and

(e) without limiting the generality of the foregoing or any other
provision hereof, any rights and benefits that might otherwise be available to
the Guarantor under California Civil Code Section 2809, 2810, 2815, 2819, 2839,
2845, 2848, 2849, 2850, 2899 or 3433.

The term "Lien" on any asset shall mean any mortgage, deed of trust, lien,
----
pledge, charge, assignment, judgment, security interest, restrictive covenant or
easement or encumbrance of any kind in respect of such asset, whether or not
filed, recorded or otherwise perfected or effective under applicable law, as
well as the interest of a vendor or lessor under any conditional sale agreement,
capital lease or other title retention agreement relating to such asset.

3.2 Waiver of Defense to Deficiency Judgment. Without limiting the
----------------------------------------
generality of any other provision of this Guaranty, the Guarantor understands
that, if the Beneficiary conducts a nonjudicial foreclosure sale under any deed
of trust or mortgage encumbering any real property owned by the Debtor and which
secures the Guaranteed Obligations, the Guarantor would (but for the waivers set
forth herein) have a defense to a deficiency judgment under this Guaranty
because the nonjudicial foreclosure would eliminate the Guarantor's right of
subrogation. This defense arises, in part, because California Code of Civil
Procedure Section 580d provides that a nonjudicial foreclosure sale under a deed
of trust eliminates the right of the secured party to seek a deficiency judgment
on the obligation secured by that deed of trust. In addition to the other
waivers set forth in this Guaranty, the Guarantor specifically waives this
defense and agrees that the Guarantor will be liable for any deficiency
remaining after a nonjudicial foreclosure even though such nonjudicial
foreclosure would eliminate the Guarantor's right of subrogation.

ARTICLE IV

WAIVER OF SUBROGATION AND CONTRIBUTION

The Guarantor hereby irrevocably waives any claims and other rights that it
now has or may hereafter acquire against the Debtor or any guarantor that arise
from the existence, payment, performance or enforcement of the Guarantor's
obligations under this Guaranty or any other Operative Document, including any
right of subrogation, reimbursement, exoneration, contribution or
indemnification and any right to participate in any claim or remedy of the
Beneficiary against the Debtor, any guarantor or any collateral that the
Beneficiary now or

-4-
<PAGE>

hereafter acquires, whether or not such claim, remedy or right arises in equity
or under contract, statute or common law, including the right to take or receive
from the Debtor, directly or indirectly, in cash or other property, by setoff or
in any other manner, payment or security on account of any such claim or other
right. If any amount is paid to the Guarantor in violation of the preceding
sentence and the Guaranteed Obligations have not been paid in full, such amount
shall be deemed to have been paid to the Guarantor for the benefit of, and held
in trust for the benefit of, the Beneficiary and shall be forthwith paid to the
Beneficiary to be credited and applied upon the Guaranteed Obligations, whether
matured or unmatured, in accordance with the terms of the other Operative
Documents. The Guarantor acknowledges that it will receive direct and indirect
benefits from the transactions and arrangements contemplated by the Asset
Purchase Agreement, the Note, the Earn-Out Agreement and the other Operative
Documents and that the waiver set forth in this ARTICLE IV is knowingly made in
contemplation of such benefits.

ARTICLE V

MISCELLANEOUS

5.1 Representation and Covenant as to Ownership of Capital Securities. The
-----------------------------------------------------------------
Guarantor represents, warrants and covenants that all of the capital stock of
the Debtor (including, without limitation, any security convertible into, or any
option, warrant or other right to acquire, any share of such capital stock) is,
and shall remain, owned by the Guarantor.

5.2 Amendments, Etc. No amendment or waiver of any provision of this
---------------
Guaranty or consent to any departure by any Guarantor therefrom shall in any
event be effective unless the same is in writing and signed by the Beneficiary,
and then such waiver or consent shall be effective only in the specific instance
and for the specific purpose for which given.

5.3 Addresses for Notices. All notices and other communications provided
---------------------
for hereunder shall be given in accordance with, and with the effectiveness
specified in, Section 9.3 of the Asset Purchase Agreement.

5.4 No Waiver; Remedies. No failure on the part of the Beneficiary to
-------------------
exercise, and no delay in exercising, any right hereunder shall operate as a
waiver thereof, and no single or partial exercise of any right hereunder shall
preclude any other or further exercise thereof or the exercise of any other
right. The remedies provided herein are cumulative and not exclusive of any
remedies provided by law.

5.5 Right of Setoff. Upon the occurrence and during the continuance of any
---------------
Default (as hereinafter defined) or Event of Default (as defined in the Note),
the Beneficiary is 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 amounts at any
time held and other indebtedness at any time owing by the Beneficiary to or for
the credit or the account of the Guarantor against any and all of the
obligations of the Guarantor now or hereafter existing under this Guaranty,
irrespective of whether the Beneficiary has made any demand under this Guaranty
and although such obligations may be contingent and unmatured. The Beneficiary
agrees to notify the Guarantor promptly after

-5-

<PAGE>

any such setoff and application made by the Beneficiary; provided, however, that
-------- -------
the failure to give such notice shall not affect the validity of such setoff and
application. The rights of the Beneficiary under this Section 5.5 are in
addition to other rights and remedies (including, without limitation, other
rights of setoff) that the Beneficiary may have. The term "Default" shall mean
-------
any event which with the passing of time or the giving of notice or both would
become an Event of Default.

5.6 Continuing Guaranty; Assignments.
--------------------------------

(a) This Guaranty is a continuing guaranty and shall (i) remain in
full force and effect until the payment in full of the Guaranteed Obligations
and all other amounts payable under this Guaranty, (ii) be binding upon the
Guarantor and its successors and assigns and (iii) inure to the benefit of and
be enforceable by the Beneficiary and their respective successors, transferees
and assigns. Without limiting the generality of the foregoing clause (iii), the
Beneficiary may assign or otherwise transfer any or all of its rights and
obligations under the Operative Documents to any other Person, and such other
Person shall thereupon become vested with all of the benefits in respect thereof
granted to the Beneficiary herein or otherwise.

(b) Without limiting the generality of the foregoing clause (a), the
Guarantor acknowledges and agrees that (i) after the execution and delivery of
the Operative Documents, Fremont shall transfer and assign all of its rights and
obligations in, to and under certain of the Operative Documents, including,
without limitation, the Note, the Earn-Out Agreement, the Security Agreement and
this Guaranty (the "Operative Document Rights"), to the partners of Fremont (the
-------------------------
"Partners"), who will, in turn, transfer and assign the Operative Document
--------
Rights to a liquidation trust (the "Trust") created for the benefit of the
-----
Partners and certain other individuals and (ii) the Trust shall, as a result of
such transfers and assignments, thereupon become vested with all of the benefits
in respect thereof granted to the Beneficiary herein or otherwise.

5.7 Governing Law and Consent to Jurisdiction. The validity, construction
-----------------------------------------
and effect of this Guaranty shall be governed by laws of the State of
California, without regard to its laws regarding choice of applicable law. Any
judicial proceedings brought against the Guarantor with respect to this Guaranty
may be brought in any state or federal court of competent jurisdiction in the
State of California, and the Guarantor accepts for itself and its assets and
properties, generally and unconditionally, the nonexclusive jurisdiction of the
aforesaid courts. The Guarantor waives, to the fullest extent permitted by
applicable law, any objection (including, without limitation, any objection to
the laying of venue or based on the grounds of forum non conveniences) that it
may now or hereafter have to the bringing of any such action or proceeding in
any such jurisdiction. Nothing herein shall limit the right of the Beneficiary
to bring proceedings against the Guarantor in the court of any other
jurisdiction.

5.8 Counterparts. This Guaranty may be executed in any number of
------------
counterparts, each of which shall be an original with the same effect as if the
signatures thereto and hereto were upon the same instrument.

5.9 Headings. Captions, headings and the table of contents in this
--------
Guaranty are for convenience only and are not to be deemed part of this
Guaranty.

-6-

<PAGE>

5.10 Security Agreement. The obligations of the Guarantor under this
------------------
Guaranty are secured by the Security Agreement executed by the Guarantor and the
Debtor in favor of the Secured Party (as defined therein).

5.11 Waiver of Jury Trial. The Guarantor waives any right to trial by
--------------------
jury with regard to any action of any type or nature whatsoever under or
concerning this Guaranty or any of the other Operative Documents or in any way
related to the administration or enforcement thereof.
